Abstract

The utility model relates to an energy-absorption and collision-damping bumper for cars, which is the safety device of cars, being composed of a surface layer bar, a reinforced preventive bar and air bag collision-damping and energy-absorption blocks which are symmetrically arranged between the surface layer bar and the reinforced protective bar. Solid elastic filler is filled around each collision-damping and energy-absorption block to form into a whole. An energy dissipation body with a honeycomb structure is arranged in each collision-damping and energy-absorption block. The energy produced by the collision of the cars can be absorbed by using compressed air which can not leak out in each independent air gas column in the holes of the honeycomb structure as the damping medium. Thus the loss of the cars and the personal casualty can be reduced. The bumper is suitable for various cars.

Description

The slow bumper/spoiler that hits of automobile energy-absorbing

The utility model is related, and to be that a kind of automobile energy-absorbing is slow hit bumper/spoiler, and it is the safety guard of automobile.

The garage had become the backbone industry of China already at present, and existing automobile reaches up to ten million, and traffic accident is also risen gradually on the thing followed road.When auto against, whole impacts of accident vehicle are at first hit thing (car) with quilt rigid impact are taken place by bumper/spoiler, cause car crash.Reason is that the bumper/spoiler of installing on the existing automobile does not absorb the slow function of hitting of Impact energy.

The utility model purpose provides a kind of automobile energy-absorbing the slow bumper/spoiler that hits at above-mentioned deficiency, and it becomes flexible bump to the rigid impact of car collision, delays the effect of impact time, reduces instantaneous impact strength, thereby alleviates automobile loss and personal casualty.

The purpose of this utility model is to realize like this.

The slow bumper/spoiler that hits of automobile energy-absorbing, by the top layer thick stick, the slow energy absorbent block of hitting of reinforcement protection thick stick and air bag is formed, it is characterized in that the slow energy absorbent block of hitting of symmetric configuration air bag between top layer thick stick and the reinforcement protection thick stick, fill by the solid elastic weighting material around hitting energy absorbent block in that air bag is slow, air bag is slow hit energy absorbent block and top layer thick stick by the nut nut with reinforce bumper/spoiler and be linked as an integral body.

The former slow flexible air-bag inside of hitting energy absorbent block of gas is the rigidity air bag, the rigidity air bag strikes out the osed top housing by steel plate, hull outside is welded with bolt of rear end plate, the damping body that is made for the air cellular structure after metal or the non-metallic sheet punching press is housed in the rigidity air bag, and the both ends of the surface at peak nest structure damping body are sealed respectively by the elastomeric material carrier through the dipping adhesion agent simultaneously.

The top layer thick stick is to make the profile body by metal or the high synthetic resin material of intensity, and the reinforcement protection thick stick is the profile body of being made by the metallic material of better mechanical property; Their profile curve is according to the place ahead or rear car body model different designs and that be installed in automobile identically.

Description of drawings:

Fig. 1-the utility model structural representation;

The slow energy absorbent block structural representation that hits of Fig. 2-air bag.

In conjunction with the accompanying drawings the utility model structure is specified: the slow bumper/spoiler that hits of a kind of automobile energy-absorbing, it is by top layer thick stick 1, reinforcement protection thick stick 3, slow energy absorbent block 2 and solid elastic weighting material 4 formations of hitting of air bag, symmetric configuration the slow energy absorbent block 2 of hitting of several air bags between top layer thick stick 1 and reinforcement protection thick stick 3, is that the foamed plastic extending agent is filled by solid elastic weighting material 4 all around in the slow energy absorbent block of hitting of air bag.Air bag is slow to hit energy absorbent block 2 and reinforcement protection thick stick by nut 5, and packing ring 6 and captive nut 7 are linked as the same, and top layer thick stick 1 constitutes complete bumper/spoiler with reinforcement protection thick stick 3 by overbolt 8 and captive nut 9 simultaneously.Top layer thick stick 1 is the profile body of being made by metal or the high synthetic resin material of intensity, reinforcement protection thick stick 3 is profile bodies of being made by the metallic material of good mechanical property, their profile curve is according to the place ahead of different automobile types body or rear curved design, and is installed in the place ahead or the rear of car body.And the slow quantity of hitting energy absorbent block 2 symmetric configurations of the air bags in top layer thick stick 1 and the reinforcement protection thick stick 3 makes it constitute entity also according to different automotive type needs and layout is full of by solid elastic weighting material 4 in the space of bumper/spoiler.

Critical component of the present utility model is the slow energy absorbent block 2 of hitting of air bag, it is by flexible air-bag 10, rigidity air bag 11, the damping body 12 of air cellular structure and elastomeric material carrier 13 constitute, the inside of flexible air-bag 10 is rigidity air bags 11, the rigidity air bag is to seal the also housing of energy stored air by steel plate through striking out, and is welded with fixed-use bolt 5 in the outside, installation site.Metal or non-metallic sheet are housed in the inside of rigidity air bag 11 are made for air cellular structure damping body 13, constitute several independently honeycomb holes, two ends at honeycomb hole are sealed respectively by the elastomeric material carrier 13 through the dipping adhesion agent, and are simultaneously also bonding with the rigidity air sac sealing.Its contact surface is reached absolutely, and the stability that has strengthened air cellular structure damping body is again leaked at the promptly stifled air gas column two ends of having cut off, and plays omnibearing sealing function.When rigidity air bag 11 is made with steel plate strike out two in addition parts and weldering be one, its joint portion uses sealing to glued joint.The internal dimensions of rigidity air bag should be consistent with the outside dimension of air cellular structure damping body 12, to prevent the circulation of air bag inner air and to leak outside.The outside of rigidity air bag 11 is flexible air-bags 10, and it selects good toughness for use, and ageing-resistant high molecular compound material is made, and its airbag wall thickness is not less than 10 millimeters, and with rigidity air bag appearance mortise.

Because slow the hitting of automobile energy-absorbing is equipped with the slow energy absorbent block of hitting of air bag in the bumper/spoiler, and slow hitting storing separately independently in its hole of hole that energy absorbent block has honeycomb structure that the air gas column can not leak.Utilize pressurized air as buffering valency matter like this, absorb the energy that vehicle clashes into mutually, it becomes flexible bump by rigid impact, delays the effect of impact time, reduces instantaneous impact strength, thereby alleviates automobile loss and personal casualty.This bumper/spoiler is applicable to various automobiles.
