Abstract

The utility model provides a car protection thick stick, includes outer plywood, cushions energy -absorbing layer and security layer, outer plywood is the glass steel sheet, outer plywood, buffering energy -absorbing layer and security layer link into an integrated entity its characterized in that: the energy -absorbing district that buffering energy -absorbing layer includes opposite direction set, comprises wave energy -absorbing board more than two -layer the top and the below in energy -absorbing district are equipped with the flat board respectively. The utility model has the advantages of three laminar structures of this protection thick stick cushion and the energy -absorbing when the vehicle bumps in proper order, and the especially special energy -absorbing district that sets up can cushion and energy release by a relatively large margin, in case the impact force still can't be overcome by whole after the energy -absorbing is distinguished, then the impact force will be exerted on special -shaped absorption cell to fracture through the absorption cell is further released. The utility model has the advantages of simple structure, buffering inhale effectual, the low cost of shaking, security good it.

Description

A kind of bumper for automobile
Technical field
The utility model relates to technical field of automobile protection, especially relate to a kind of when there is good logical contingency, the bumper for automobile of driver and crew's safety in vehicle can be increased.
Background technology
Bumper for automobile is the safety device absorbing and cushion foreign impacts power, protection vehicle body front and rear part.Teacher's Bumper is based on metallic material, and the general thickness that adopts is that the steel plate stamping of more than 3 millimeters is pressed into U-lag steel, surface row chromium plating process support again, during installation and vehicle frame rivet or weld together.
Along with the development of auto-industry, modern automobile Bumper, except keeping original function, also needs the lightweight pursuing itself.Therefore, secondly material has changed plastic material bumper/spoiler into from initial steel plate, generally by outside plate, padded coaming and crossbeam three part form, wherein outside plate and padded coaming are plastic material, the outer cold-rolling thin plate of crossbeam, outside plate and padded coaming are attached on crossbeam, and crossbeam is connected with chassis side rail, can disassemble at any time.This kind of interlayer be the safety bar of individual layer padded coaming when Traffic Accidents occurs, to goers outside vehicle and unpowered vehicle injury comparatively large, and when clashing into serious because of its buffering energy-absorbing ability, really effectively cannot play safety protection function.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existed in prior art, the bumper for automobile of a kind of energy available protecting pedestrian and passenger when there is traffic accident is provided, this Bumper is due to the setting of its buffering energy-absorbing layer and security layer, effectively reduce shock and vibration when collision produces, improve vehicle safety, the technical scheme adopted is: a kind of bumper for automobile, comprise lamina rara externa, buffering energy-absorbing layer and security layer, described lamina rara externa is glass epoxy, described lamina rara externa, buffering energy-absorbing layer and security layer link into an integrated entity, it is characterized in that: described buffering energy-absorbing layer comprises subtend and arranges, the energy-absorbing district be made up of two-layer above waveform energy-absorbing plate, flat board is respectively equipped with above and below described energy-absorbing district.
Technical characteristic of the present utility model also has: straight pin is pinned by lock pin through after described lamina rara externa gentle suction ergosphere, and described straight pin is equipped with recoil spring.
Technical characteristic of the present utility model also has: between the flat board of described recoil spring above lamina rara externa and buffering energy-absorbing layer.
Technical characteristic of the present utility model also has: security layer one end is fixedly connected on the flat board of described buffering energy-absorbing layer, and other end bolt is connected on vehicle frame.
Technical characteristic of the present utility model also has: described security layer is made up of steel plate.
The beneficial effects of the utility model are: the three layers structure of this Bumper cushions and energy-absorbing successively when collision happens, especially the special energy-absorbing district arranged can cushion by a relatively large margin and release can, once impulsive force also cannot all be overcome behind energy-absorbing district, then impulsive force will be applied on special-shaped absorption cell, and be discharged further by the fracture of absorption cell.The utility model has the advantage that structure is simple, buffering shock attenuation result is good, with low cost, safety is good.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation, and accompanying drawing 2 is security Rotating fields schematic diagrams in accompanying drawing 1, and wherein, 1 is lamina rara externa, and 2 is waveform energy-absorbing plates, and 3 is straight pins, and 4 is lock pins, and 5 is recoil springs, and 6 is dull and stereotyped, and 7 is special-shaped absorption cells.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.The utility model discloses a kind of new automobile Bumper, this bumper for automobile comprises lamina rara externa 1, buffering energy-absorbing layer and security layer, and lamina rara externa 1 is glass epoxy, and lamina rara externa 1 makes required form as required, to increase the cosmetic look of bumper for automobile.Lamina rara externa 1, buffering energy-absorbing layer and security layer link into an integrated entity.
Buffering energy-absorbing floor comprises energy-absorbing district, and this energy-absorbing district is arranged by subtend, two-layer above waveform energy-absorbing plate 2 is formed, and so-called subtend is arranged, and refers to the height point of adjacent wave shape wave energy-absorbing plate 2 to high point, low spot to low spot, the effect of such guarantee buffering energy-absorbing." waveform ", in order to describe the shape of energy-absorbing plate, the spikes/low-points namely on plate is uniformly distributed, and is also respectively equipped with dull and stereotyped 6 above and below energy-absorbing district.Straight pin 3 is pinned by lock pin 4 through after the gentle suction ergosphere of lamina rara externa 1, and straight pin 3 is equipped with recoil spring 5.Between the flat board 6 of recoil spring 5 above lamina rara externa 1 and buffering energy-absorbing layer.
Security layer is special-shaped absorption cell 7, and " abnormity " refers to the out-of-shape of security layer, as long as its one end can be fixedly connected on the flat board of buffering energy-absorbing layer, other end bolt is connected on vehicle frame, and centre has at least one bends.In present embodiment, security layer is made up of steel plate.
Employ four recoil springs 5 in present embodiment, be arranged on respectively on four straight pins 3, and recoil spring 5 rotation direction is different, as one of them is left-handed recoil spring, then another is dextrorotation recoil spring.
During use, this bumper for automobile is in place, once collide in travelling, first lamina rara externa 1 is stressed, when the gentle suction ergosphere of lamina rara externa 1 all cannot overcome this impulsive force completely, the special-shaped absorption cell 7 of security layer absorbs impulsive force further by distortion own, and then the personnel that reduction accident may cause injure and vehicle deformation.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
