Embodiment describes
The stagewise damping device of the application may apply to different field, for instance sporting goods, equipment, footwear take class or wearable device and accessory etc. need the product of shock attenuation needs in various degree。Further, the shock attenuation needs according to individual product, it is possible to select the material of different physical property, for instance plastics, nylon, expanded material or elastic metallic etc., assist to realize stagewise shock-absorbing function。Additionally, according to practical application, the damping device of the application can look actually used demand, adopt and cover comprehensively or be applied topically on the product of different area or volume, and be not limited to specific setting direction and form。Meanwhile, the surface structure form of stagewise damping device can be square, circle or other forms, for instance square, rectangle or 360 ° loop configuration etc., and not only terminate in specific single structure form。
As shown in Figure 1, the stagewise damping device 10 that the application first embodiment provides includes bottom 110, top layer 120 and multiple elastic arm 130, and wherein bottom 110, top layer 120 and each elastic arm 130 can be but be not limited to be made up of in integrated mode identical material；Or in damping device, at least elastic arm 130 is that the elastomeric material when stress with good elastic deformation force and elastic-restoring force is formed by plastics, nylon, expanded material or elastic metallic etc.。In the present embodiment, it is be formed in one structure as an example with stagewise damping device 10, but is not limited thereto。
Multiple elastic arms 130 of stagewise damping device 10 are connected between bottom 110 and top layer 120, and it is spaced along horizontal direction, top layer 120 is made to be arranged at the top of bottom 110, and can relative to bottom 110 shift reciprocately, namely top layer 120 can be oppressed elastic arm 130 and be produced elastic deformation and towards the direction displacement of bottom 110；Or be directed away from the direction displacement of bottom 110 by the elastic-restoring force after elastic arm 130 pressurized, and it is supported in original position by elastic arm 130。
In the present embodiment, each elastic arm 130 includes first pole the 131, second pole 132 and connecting rod 133, first pole 131 is connected to relative two ends of connecting rod 133 with the second pole 132, wherein one end of the first pole 131 is connected to top layer 120, the other end tilts to be connected to connecting rod 133, thus forming the point of inflexion 134 in the junction of the first pole 131 with connecting rod 133；And one end of the second pole 132 is connected to bottom 110, the other end tilts to be connected to connecting rod 133 along the parallel or rough direction being parallel to the first pole 131, thus forming the lower point of inflexion 135 in opposite direction with the upper point of inflexion 134 the second pole 132 with the junction of connecting rod 133, and the upper point of inflexion 134 lays respectively at relative two sides of elastic arm 130 with the lower point of inflexion 135, the mode of appearance of elastic arm 130 is made to present lightning shape structure。
In addition, the connecting rod 133 of elastic arm 130 tilts to be connected between the first pole 131 and the second pole 132 along the direction being different from the first pole 131 and the second pole 132, namely between the upper point of inflexion 134 and the lower point of inflexion 135, thus allow the point of inflexion 134 horizontal level normality higher than the horizontal level of the lower point of inflexion 135, that is, it is located close to the side of top layer 120 in the space that the upper point of inflexion 134 is constituted between bottom 110 and top layer 120, and the lower point of inflexion 135 is located close to the side of bottom 110。
What deserves to be explained is, when above-mentioned elastic arm 130 is subject to the extruding of longitudinal direction, such as, when extruding from the first pole 131 towards the direction of the second pole 132, the strength oppressed on the first pole 131 will force to promote connecting rod 133 to reverse along direction clockwise or counterclockwise by the upper point of inflexion 134, this depends on that the incline direction of original state lower link 133 is determined, the present embodiment is to reverse as an example in the counterclockwise direction with connecting rod 133, but is not limited thereto。When one end that connecting rod 133 is connected to the upper point of inflexion 134 rotates, connecting rod 133 is connected to one end of the lower point of inflexion 135 will pass through lever principle, raise 135 displacements in the counterclockwise direction of lower contrary flexure in the lump, thus allowing the lower point of inflexion 135 and the upper point of inflexion 134 respectively with the center of connecting rod 133 for axle center, and the relative displacement of the relative two ends generation horizontal levels at connecting rod 133 so that the first pole 131 and the second pole 132 are respectively facing the direction displacement of connecting rod 133 and mutually fold and draw close。
In above-mentioned loading process, connecting rod can store energy under the compressive state of elastic arm, and is discharged by stored energy when elastic arm is replied as original state from compressive state。Therefore, when connecting rod 133 be subject to the upper point of inflexion 134 promotion and from initial incline direction gradually when turning to horizontal direction, such as turn to 9 o'clock direction from 11 o'clock direction, the direction that first pole 131 and the second pole 132 are respectively facing bottom 110 and top layer 120 along with the torsion of connecting rod 133 is stretched, and allows connecting rod 133 retentivity in the horizontal direction balance。Then, when the downforce that top layer 120 applies overcomes the flexural stress of elastic arm 130, the upper point of inflexion 134 puts on the connecting rod 133 dynamic balance along the strength destruction horizontal direction of counterclockwise lasting rotation, and oppress connecting rod 133 and turn to another incline direction, thus driving the horizontal level of the upper point of inflexion 134 and the lower point of inflexion 135 to be respectively facing the direction displacement of bottom 110 and top layer 120 and mutually overturn, such as turn to 7 o'clock direction from 9 o'clock direction, the lower point of inflexion 135 is driven to be moving in a counterclockwise direction along with the rotation of connecting rod 133 with the upper point of inflexion 134 in the lump, the first pole 131 and the second pole 132 is made to be respectively facing the direction stretcher strain of bottom 110 and top layer 120, and be respectively facing connecting rod 133 and draw close。
Afterwards, when the extruding force putting on longitudinal direction releases, the first pole 131 and the second pole 132 can be respectively facing the direction contraction of top layer 120 and bottom 110 by the elastic-restoring force of itself, and drivening rod 133 reverses along clockwise direction in the lump。Now, the torsion when elastic-restoring force of elastic arm 130 contains the contractility of the first pole 131 and the second pole 132 and connecting rod 133 rotates, allow elastic arm 130 can reply the original form before into pressurized under the drive of these active forces rapidly。
Hereinafter the start principle of above-mentioned stagewise damping device 10 and the beneficial effect that can be generated by are described further。
Refer to Fig. 2 and Fig. 6, in application, when the impact force action from the external world is on the top layer 120 of stagewise damping device 10, be positioned at the elastic arm 130 below impulsive force can be subject to top layer 120 extruding and towards bottom 110 direction produce elastic deformation, such as, if stagewise damping device 10 is applied to footwear bottom, human foot is trampled in downforce produced by top layer 120, make the top layer 120 direction displacement towards bottom 110, and oppress elastic arm 130 and produce elastic deformation, especially the deflection being positioned at the elastic arm 130 immediately below impulsive force can more than the elastic arm 130 being distributed in surrounding。Wherein, at impact force action in the initial stage of top layer 120, top layer 120 is linearly distributed (position that the arrow a such as Fig. 6 indicates) towards the acceleration of gravity of bottom 110 displacement, now, owing to the connecting rod 133 of elastic arm 130 and the incline direction of the first pole 131 and the second pole 132 are different, and vertical direction is provided by connecting rod 133 or is parallel to the support force in impulsive force direction, so that elastic arm 130 only produces slightly to deform。
Refer to Fig. 3 and Fig. 6, increase along with impulsive force, when top layer 120 is moved to the first buffer position P1 towards bottom 110, the upper point of inflexion 134 of elastic arm 130 is subject to the compressing of top layer 120 and towards bottom 110 displacement, the connecting rod 133 promoting elastic arm 130 in the lump reverses to horizontal direction from original incline direction, and raises the lower point of inflexion 135 towards top layer 120 displacement。Now, by the torsion of the connecting rod 133 of elastic arm 130 so that the impulsive force of part is led to horizontal direction from vertical force direction, thus reducing the impact power acting on top layer 120, and the cushioning effect of first stage is reached。Furthermore, in elastic arm 130, along with the torsion counterclockwise of connecting rod 133 so that the first pole 131 is subject to pullling of connecting rod 133, and towards bottom 110 direction stretcher strain, thus being created towards the elastic-restoring force in top layer 120 direction；Similarly, second pole 132 is also affected by pullling of connecting rod 133, and towards top layer 120 direction stretcher strain, thus being created towards the elastic-restoring force in bottom 110 direction, thus, connecting rod 133 can be subject to the elastic-restoring force effect of the first pole 131 and the second pole 132 and produce the torsion reversed clockwise, make to cause the impulsive force of torsion to be counterclockwise subject to the opposing of this clockwise direction torsion and cut down on connecting rod 133, thus allowing top layer 120 slow down towards the acceleration of gravity moment of bottom 110 displacement, then again (position that the arrow b such as Fig. 6 indicates) is accelerated again, so, can effectively relax impact force action moment power on stagewise damping device 10。
Refer to Fig. 4 and Fig. 6, it is moved to the second buffer position P2 when top layer 120 is continued towards bottom 110, now act on the strength size of the impulsive force of top layer 120 to have surmounted the connecting rod 133 of elastic arm 130 and keep the limit stress of balance in the horizontal direction, when namely coming from the flexural stress that the downforce of top layer 120 overcomes elastic arm 130, cause the dynamic balance unstability (buckling) acting on connecting rod 133, and it is subject to the promotion of the upper point of inflexion 134, along counterclockwise reversing to another incline direction, drive the lower point of inflexion 135 and the upper point of inflexion 134 relative position in the horizontal direction mutually to overturn simultaneously, make the horizontal level horizontal level lower than the lower point of inflexion 135 of the point of inflexion 134。And, when impulsive force or acceleration of gravity reach maximum (position that the arrow c such as Fig. 6 indicates), the direction compression that first pole 131 of elastic arm 130 and the second pole 132 are respectively facing connecting rod 133 is folding, and play absorption, cut down the effect of impulsive force, thus providing the cushioning effect of second stage。
Refer to Fig. 5 and Fig. 6, afterwards, when the impact power acting on top layer 120 declines, such as, when human foot completes trample action on the ground by stagewise damping device 10, and when starting to lift foot, due to slowing down of impulsive force, make on connecting rod 133, cause the impulsive force reversed the counterclockwise clockwise direction torsion produced less than connecting rod 133 gradually by elastic-restoring force effect, so that top layer 120 is subject to the elastic-restoring force effect of elastic arm 130 and is first raised to the first buffer position P1, then removing along with impulsive force again, after making elastic arm 130 reply the configuration before for compression, just top layer 120 is raised back original position。In the process, when acceleration of gravity during due to top layer 120 away from bottom 110 displacement reaches certain numerical value, first pass through the dynamic balance effect that the connecting rod 133 of elastic arm 130 provides in the horizontal direction, the rebound velocity allowing elastic arm 130 somewhat slows down (transition location that the arrow d such as Fig. 6 indicates), then with certain rebound velocity, top layer 120 is raised back original position again。Thus, it is possible in more unified time interval, reply the energy stored, in this way, elastic arm 130 structure adopted in the stagewise damping device 10 of the application can allow efficient and unified energy reply at correct time point。
It is understood that in some embodiments of the application, it is possible to multiple elastic arms are symmetrical arranged in the horizontal direction, for instance, multiple elastic arms are arranged in equally spaced mode；Or by positive and negative staggered in the way of arrange。Wherein, if being disposed at equal intervals, the adjacent spacing between two elastic arms, can be when top layer is moved to the first buffer position, the upper point of inflexion of one of them and another the lower point of inflexion in adjacent two elastic arm is made mutually to support, so that the connecting rod of elastic arm is when upset is to horizontal direction, it is possible to have support force in the horizontal direction, and significantly more efficient horizontal direction that the impulsive force of vertical direction is directed to, in order to slow down impulsive force。Additionally, if during with positive and negative being crisscross arranged, two adjacent elastic arms in opposite direction, the upper point of inflexion or the lower point of inflexion of two namely adjacent elastic arms are arranged face-to-face, now, when top layer is moved to the first buffer position, the upper point of inflexion or the lower point of inflexion of two adjacent elastic arms can push against mutually, thus promoting connecting rod support force in the horizontal direction。
As shown in Figure 7, the application the second embodiment is structurally roughly the same with first embodiment, difference between the two is in that, in the stagewise damping device 20 that the second embodiment provides, first pole 231 of elastic arm 230 and the second pole 232 are respectively facing rightabout bending, and present arc structure or the configuration of 1/4 circle, the mode of appearance making elastic arm is S character form structure, thus forming the point of inflexion at the dome point of the first pole and forming the lower point of inflexion at the dome point of the second pole, such as it is respectively formed at the position of 1/2 length of the first pole 231 and the second pole 232。
Additionally, in this example, multiple elastic arms 230 can be arrange at equal intervals or positive and negative be crisscross arranged, it is preferable that multiple elastic arms 230 by positive and negative staggered in the way of arrange, and in pairs, and be symmetrical arranged, and be uniformly distributed。Wherein, the elastic arm 230 of every a pair includes elastic arm 230 and the oppositely arranged elastic arm 230 that a forward is arranged, the upper point of inflexion 234 making two elastic arms 230 is drawn close mutually, and the lower point of inflexion 235 is separated from each other, thus forming the lower cushion chamber 240 of hollow between the second pole 232 of two paired elastic arms 230, and between the first pole 231 of the elastic arm 230 of adjacent two pairs, form the upper cushion chamber 250 of hollow, make lower cushion chamber 240 and upper cushion chamber 250 be staggered along horizontal direction。
The effect hereinafter lower cushion chamber and upper cushion chamber played, the start principle of stagewise damping device 20 and the beneficial effect that can be generated by thereof are described further。
Refer to Fig. 8 and Figure 13, in application, when the impact force action from the external world is on the top layer 220 of stagewise damping device 20, be positioned at each elastic arm 230 below impulsive force can be subject to top layer 220 extruding and towards bottom 210 direction produce elastic deformation, the deflection being especially positioned at two pairs of elastic arms 230 immediately below impulsive force can more than all the other elastic arms 230 of stress point periphery。Further, due to the compression of elastic arm 230, make the curvature of the first pole 231 and the second pole 232 from the flexural deformation along with the first pole 231 and the second pole 232 gradually of the minima of original state and cumulative。In this stage, the acceleration of gravity that top layer 220 is moved to the first buffer position P1 towards bottom 210 is linearly distributed (position that the arrow a such as Figure 13 indicates), and the upper point of inflexion 234 making elastic arm 230 is subject to the compressing of top layer 220 and towards bottom 210 displacement, the connecting rod 233 promoting elastic arm 230 in the lump overturns to horizontal direction from original incline direction, and raises the lower point of inflexion 235 towards top layer 220 displacement。
The configuration mode to horizontal direction is overturn along with force by the connecting rod of elastic arm 230 233, allow elastic arm 230 except having support force in the vertical direction, the upset of connecting rod 233 can also be passed through, push towards horizontal direction, thus in the upper point of inflexion 234 of two paired elastic arms 230 towards in the process of bottom 210 direction displacement, relative two sides of the lower cushion chamber 240 of compressing are respectively in the horizontal direction towards the direction expansion being located remotely from each other；Similarly, in the lower point of inflexion 235 of two paired elastic arms 230 towards in the process of top layer 220 direction displacement, in compressing, relative two sides of cushion chamber 250 are respectively in the horizontal direction towards the direction expansion being located remotely from each other。Support and the function of buffering consequently, it is possible to elastic arm 230 also can be played in the horizontal direction。
Refer to Fig. 9, 10 and 13, increase along with impulsive force, when top layer 220 be continued towards bottom 210 be moved to the second buffer position P2 time, act on the strength size of the impulsive force of top layer 220 to have surmounted the connecting rod 233 of elastic arm 230 and keep the limit stress of balance in the horizontal direction, cause the dynamic balance unstability (buckling) acting on connecting rod 233, connecting rod is made to be subject to the promotion of the upper point of inflexion 234, and along overturning to another incline direction (angle) counterclockwise or clockwise, the lower point of inflexion 235 is driven mutually to reverse at relative two ends of connecting rod 233 with the upper point of inflexion 234 in the lump, make the horizontal level horizontal level lower than the lower point of inflexion 235 of the point of inflexion 234, the upper point of inflexion 234 of two wherein paired elastic arms 230 is placed in lower cushion chamber 240；And make the lower point of inflexion 235 of the elastic arm 230 of adjacent two pairs be placed in cushion chamber 250, the displacement stroke respectively go up point of inflexion 234 and the lower point of inflexion 235 thereby through lower cushion chamber 240 and upper cushion chamber 250 provides nargin, it is to avoid the upper point of inflexion 234 and the lower point of inflexion 235 direct collision bottom 210 and top layer 220 and produce the counteracting force in large force road。
Meanwhile, along with the upset of connecting rod 233, the first pole 231 is subject to one end of connecting rod 233 and pulls and towards bottom 210 direction stretcher strain, thus being created towards the elastic-restoring force in top layer 220 direction；Similarly, second pole 232 is subject to the other end of connecting rod 233 and pulls and towards top layer 220 direction stretcher strain, thus being created towards the elastic-restoring force in bottom 210 direction, thus, connecting rod 233 can be subject to the elastic-restoring force effect of the first pole 231 and the second pole 232 and produce the torsion overturn clockwise, the first pole 231 is made to draw close towards connecting rod 233 in relative two sides of connecting rod 233 respectively with the second pole 232 and mutually fold, and make to act on the torsion opposing causing the impulsive force of upset to be subject to rotating on connecting rod 233 in rightabout and moment cuts down, thus allowing top layer 220 stagnate towards speed moment of bottom 110 displacement, then (crest location that the arrow b such as Figure 13 indicates and the wave trough position that the arrow c of Figure 13 indicates) is again accelerated again, thus, at force of the breath produced by stagewise damping device 20, abirritation is provided for impulsive force。
Refer to Figure 11 and Figure 13, when impulsive force or acceleration of gravity reach maximum (position that the arrow d such as Figure 13 indicates), the relative bottom 210 of top layer 220 is moved to the 3rd buffer position P3, the upper point of inflexion 234 and the lower point of inflexion 235 that make elastic arm 230 reach minimum with the distance of bottom 210 and top layer 220 respectively, and allow lower cushion chamber 240 extend into maximum in the opposite direction with relative two sides of upper cushion chamber 250, thus in the process that lower cushion chamber 240 and upper cushion chamber 250 extend along horizontal direction, lasting for the impulsive force of vertical direction is dispersed to horizontal direction。Meanwhile, the first pole 231 of elastic arm 230 and the second pole 232 are respectively facing the direction compression of connecting rod 233 and fold into the limit, thus absorbing, having cut down the impulsive force of vertical direction。
Refer to Figure 12 and Figure 13, afterwards, when the impulsive force acting on top layer 220 declines, such as, when human foot starts to be lifted up, along with slowing down of impulsive force, connecting rod 233 is made to be subject to twisting force and begin turning, but, lower cushion chamber 240 shrinks along horizontal direction in the same time with relative two sides of upper cushion chamber 250, allow connecting rod 233 before upset to horizontal level or original obliquity, it is subject to the contraction of lower cushion chamber 240 and upper cushion chamber 250 and produces to hinder, thus when acceleration of gravity when allowing top layer 220 away from bottom 210 displacement reaches certain numerical value, can somewhat slow down (transition location that the arrow e such as Figure 13 indicates), then original position is raised back with certain speed again。
