Description
Technical field
The present invention relates to field of shock absorption, is specially a kind of annelidan bionical shock-damping structure of imitation.
Background technology
With the appearance of increasing precision instrument, the requirement for its protecting against shock damping is also more and more.It is and big
Most precision instruments are all high precision instruments, require high to operating environment, and a bit rocking also can produce shadow to detection structure
Ring.
Existing shock-damping structure is mostly the several types such as spring, hydraulic type, electromagnetic type, and spring utilizes spring itself
Deformation absorbs impact damping, but deformation is still along impact direction, and up-down vibration repeatedly occurs during damping,
The amplitude rate of decay is small, is unfavorable for the demand for meeting the damping of the equipment such as secret instrument；The shock-damping structure of hydraulic type then easily goes out
Existing oil leak, while manufacturing process is cumbersome, low production efficiency.Spring is more heavy with hydraulic type damper, installs mobile difficulty,
It is not suitable for the precision instrument of exquisiteness.Though electromagnetism can be made more compact, electromagnetic type itself carries electromagnetic field, influences accurate instrument
The operating of device itself.
The content of the invention
In view of the above-mentioned problems, the invention provides it is a kind of imitate annelid leech bionical shock-damping structure and structure, its
With damping efficiency is high, simple in construction, Maintenance free, easily manufactured and light various features such as reliable.
The technical solution adopted for the present invention to solve the technical problems is：
One kind imitates annelidan bionical shock-damping structure, including some folds equidistantly arranged and is disposed above
Cushion, be arranged at roller below, wherein the fold is stretchable with cushion.The shock-damping structure is bionical in link
Animal leech epidermis, for its V-type fold when running into vertical impact power, the extruding of longitudinal direction is changed into horizontal stretching, extension by V-type fold, is made
Catenary motion in impact is converted into transverse movement, while increasing time of contact the deformation of V-type fold can also absorb largely
Impact energy, play a part of damping.
As the improvement of above-mentioned technical proposal, the fold is V-type fold, and the cushion includes the different upper strata of hardness
Cushion pad and lower floor's cushion pad, the roller is flexible roller, and it is connected to below V-type fold by roller bearing.
As the improvement of above-mentioned technical proposal, the hardness of the upper strata cushion pad is less than lower floor's cushion pad hardness, i.e.,
Cushion includes softer upper strata cushion pad and harder lower floor's cushion pad.
The operation principle of the bionical shock-damping structure includes：
Step A, in impact process, flexible roller contacts ground at first, absorbs part impact itself producing deformation
While kinetic energy, also impulsive force is delivered on V-type fold, under external force, V-type fold stretches rapidly flat, the deformation
Further absorb impact kinetic energy；
Step B, the stretching, extension of V-type fold drive its lower flexible roller to outer rolling, ensure that fold will not can not because of friction
Stretching, extension, also softer upper strata cushion pad and harder lower floor's cushion pad are stretched, stretcher strain will absorb substantial amounts of impact kinetic energy；
The stretching of step C, softer upper strata cushion pad and harder lower floor's cushion pad can make the reduction of its longitudinal thickness, V-type
Fold deforms with softer upper strata cushion pad and harder lower floor's cushion pad, reduces longitudinal overall height, adds time of contact,
The substantial amounts of impact kinetic energy absorbed with reference to stretcher strain, the effect of damping is realized with this.
As the improvement of above-mentioned technical proposal, the V-type fold has certain modulus of elasticity, it is protected when without external force
Original state is held, the rapid cross directional stretch when there is external force.
As the improvement of above-mentioned technical proposal, the upper strata cushion pad has certain modulus of elasticity with lower floor's cushion pad,
Its modulus of elasticity is less than the modulus of elasticity of the V-type fold, and while stretching absorption impact kinetic energy, longitudinal thickness reduces, and increases
Add damping effect.
As the improvement of above-mentioned technical proposal, close phase between the upper strata cushion pad, lower floor's cushion pad and V-type fold
Even, original shape is kept during no external force, when having external force, the upper strata cushion pad, lower floor's cushion pad provide additionally for V-type fold
Lateral pull, more impact kinetic energies are absorbed, increase damping effect.
As the improvement of above-mentioned technical proposal, the flexible roller has certain modulus of elasticity, makes it absorbable one
Divide impact kinetic energy, increase damping effect.
The beneficial effect that the present invention is brought has：
1st, bionical shock-damping structure of the invention mainly utilizes the V-type fold for imitating annelid leech pair different from hardness
The stretchable cushion pad of layer realizes there is the characteristics of good damping effect, durable in use.
2nd, not only structure design is compact simple for bionical shock-damping structure of the invention, and production cost is low, the spy of Maintenance free
Point.
3rd, bionical shock-damping structure of the invention is not required to the damping auxiliary of oil, will not cause oil leak and environmental pollution, while
Without electromagnetic device, will not produce operating cost will not also produce electromagnetic field.
4th, the present invention is unique innovative design, in a sense departing from traditional shock-damping structure and mounted cast,
Compared to the damping device of existing most designs, will have and more be widely applied space.
