Description
Technical field
The utility model relates to automotive field, is a kind of collision of motor-driven vehicles buffer protection device specifically.
Background technology
Along with the increase of automobile pollution, people more and more pay attention to the safety of automobile.Bumper/spoiler is positioned at the place ahead of automobile, the ability in the time of can absorbing Vehicular impact, thereby protection automotive engine and passengers inside the car's safety.Existing safety lever adopts elastic energy absorbing device to absorb the kinetic energy that collision produces usually, also have and utilize the distortion of metal to carry out absorbing impact energy, as Chinese Patent Application No.: 201010003524.8 applyings date: 2010-01-12, name is called: bumper damper, the applicant: German Benteler Automobiltechnik GmbH discloses a kind of bumper damper for automobile, comprise one can be transverse to the fixing crossbeam of the longeron of automobile frame; That the cross-sectional configuration of crossbeam becomes U-shaped and there are a fishplate bar and two sides; The fishplate bar of crossbeam is towards automobile.In front side, crossbeam seals by reinforcing profile; Reinforcing profile is configured to hollow profile and has the cross-sectional plane of T shape.In addition, Chinese Patent Application No.: 200710151733.5, the applying date: 2007-09-27, name is called " bumper of vehicles ", applicant: Toyota Motor Corporation rep. also discloses a kind of bumper of vehicles.In described bumper of vehicles, by adopting assembly unit, replace adopting bolt, rear bumper energy disperser and the postbrachium of rear bumper are interconnected.In addition, adopt duct member to replace the rear bumper reinforcement feature, and described duct member is placed in the recess formed together with described rear bumper energy disperser.As a result, described rear bumper energy disperser and described duct member combine the energy absorption performance that provides higher.Use installation step to replace the bolt Connection Step, make fitting work simpler and easy.In addition, owing to no longer needing described rear bumper reinforcement feature, so lighter bumper/spoiler is provided.Similarly patent is many in addition, but they have a common ground, can't guarantee to clash into exactly the rebound effect of rear vehicle, just not saying utilize the shock absorber of elastic element, after elastic element absorbs and clashes into kinetic energy, the release of elastic potential energy must cause the bounce-back of vehicle; And there is Similar Problems too in the distortion of patent utilization metal construction above-mentioned, because metal all has elasticity, when occurring to clash into, after flow of metal, often only overlap, the resilient property of metal causes elastic potential energy to discharge, and can cause equally the bounce-back of vehicle; And the bounce-back of vehicle tends to cause passengers inside the car's head to produce whipping effect, that is: the little outshot at top due to quality and rigidity smaller, turnover moment back and forth at each, form larger speed, produce larger displacement, just the same with the point of whip, this phenomenon is called whipping effect.This be because, safety strap fetters the torso portion of human body, but head is free end, when auto against, torso portion is fettered by safety strap, speed is consistent with vehicle body speed, but head is the speed before collision, due to the torso portion cut, and be subject to the effect of screen resilience, torso portion stops backward direction of retreat motion, and head moves on, as whipping effect, the resilience that above-mentioned patent all produces torso portion when collision, do not solve the destructiveness infringement that whipping effect causes passenger's neck.

The specific embodiment
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Fig. 1-Fig. 6, comprise bumper/spoiler 1, stressed plate 23, gas compression cylinder 5, bracing frame 4, shear bolt 8, decompression exhaust valve 6; Described bumper/spoiler 1 back arranges stressed plate 23; Described stressed plate 23 is connected with the piston end of gas compression cylinder 5; The cylinder body bottom of described gas compression cylinder 5 arranges multi-step pressure reduction blow off valve 6; Described gas compression cylinder 5 is arranged in bracing frame 4; Support frame as described above 4 one ends and stressed plate 23 are fixing, and an other end is fixed on self-propelled vehicle main frame beam 9 by shearing bolt 8.
The impact transmitted for the assurance thick stick is consistent with the compression direction of gas compression cylinder 5 as much as possible, described bumper/spoiler 1,23 of stressed plates arrange stressed plate 1, the width of described stressed plate 1 is greater than the width of stressed plate 23, and 23 of described stressed plate 1 and stressed plates arrange spring 10.
As shown in Figure 5, but for saving the installing space of vehicle bumper back, and buffering percussive force, described gas compression cylinder 5 is multistage, and, from the second stage, the cylinder body of every one-level is the piston of next stage, except the cylinder body of the first order and afterbody, the bottom of other every grade cylinder body arranges air extractor vent 52.
For further guaranteeing the safety of self-propelled vehicle main frame beam 9, support frame as described above 4 arranges gas compression cylinder 5 with self-propelled vehicle main frame beam 9.
As shown in Figure 7; described shearing bolt 8 is many groups; and it is different from the gap of self-propelled vehicle main frame beam 9 that each group is sheared bolt 8; along the tailstock to headstock direction change from small to big (or from large to small); can guarantee so the progressively increase along with the degree of clashing into; shear bolt 8 and cut off by following, protected the vehicle main frame beam, also shock has been produced to buffer action.In Fig. 7, gap 91 is less than gap 92, guarantees at first to shear following shearing bolt, and then shears top shearing bolt.
As shown in Figure 6, for guaranteeing that the shock come by inclined-plane converts positive impulsive force to, described gas compression cylinder 5 piston head faces 51 are sphere, the impact on inclined-plane can resolve into positive impact and the impact of side like this, and the impact of side is absorbed by spring, positive impact is absorbed by device of the present utility model.
As shown in Figure 4, for further playing sorption, support frame as described above 4 is outwards heaved, and described position of heaving arranges gap 41, like this when clashing into generation, bracing frame 4 is outwards heaved, due to stress concentration effect, when impact is larger, from gap 41 places fracture, guarantee that gas compression cylinder 5 can compress fully, thereby absorb, clash into kinetic energy.
For protection self-propelled vehicle main frame beam and the further shock kinetic energy that absorbs, between described support frame as described above 4 and self-propelled vehicle main frame beam 9, multistage compression cylinder 5 is set.
Described multi-step pressure reduction blow off valve refers to a plurality of blows off valve of compressor cylinder bottom installation, and the startup exhaust gas pressure of setting each blow off valve does not wait, like this, increase gradually along with pressure, blow off valve also progressively starts thereupon, gas is discharged, thereby reach the purpose of decompression, by decompression exhaust step by step, make compressor cylinder not there is bounce-back in compression process.Described blow off valve can adopt commercially available prod.
