Abstract
The utility model discloses a car body buffer stop, including crossbeam, two energy -absorbing boxes and two energy -absorbing box welded plates, two energy -absorbing box welded plates on respectively the welding have an energy -absorbing box, the both ends of crossbeam weld respectively on two energy -absorbing boxes, energy -absorbing box welded plate be some styles of calligraphy, and be provided with a plurality of through -holes on the energy -absorbing box welded plate. The utility model discloses wellly adopted some styles of calligraphy welded plates, be provided with grooved surface on the outer terminal surface of crossbeam to adopt the energy -absorbing box structure that is provided with the energy -absorbing muscle, spent big the time when the impact, can play fine cushioning effect.
Description
Technical field
The utility model belongs to auto body security appliance field, is specifically related to a kind of auto body anticollision device.
Background technology
Current road traffic accident is increasing gradually, and it is one of the important quality index of modern automobile that the safety performance of automobile has become.How when automobile generation traffic dangerous state, safe, the damage that is that reduce automobile vitals of occupant is protected to be the directions of each motor plant research and development to greatest extent.The anticollision device of automobile be exactly device vehicle first time bearing impact, if some positions of car body receive shock, iff allowing this position go holding capacity, the protected effect so reached can be very poor.If when certain is a bit subject to power, allow whole skeleton structure go holding capacity, then can reduce the intensity of this power suffered by point to greatest extent, particularly, collision prevention girders just plays effect clearly here.
In front anti-collision beam design; need to consider many-sided requirements such as pedestrian protecting, low speed collision laws and regulations requirement, head-on crash, offset collision; but existing front Crashworthy plate structure; when satisfied signature each side requires; but correspondingly reduce the requirement absorbing more impact energys in an impact, thus bring very large potential safety hazard to driver and crew.
In the like product of existing anti-collision device for automobile, with the U-lag of cold-rolling steel-plate punch, be connected with chassis side rail, front anticollision beam assembly structure for automobile also exists and bears high, low speed impact resistance power out of reach laws and regulations requirement, do not ensure the safety to navigating mate, desirable strength buffering effect cannot be reached.
Utility model content
The utility model provides a kind of auto body anticollision device, and this device can reduce the infringement of impact to vehicle body effectively, and a few font welded plate can be good at playing energy-absorbing function.
The technical solution of the utility model is as follows: a kind of auto body anticollision device, comprise crossbeam, two energy-absorption boxes and two energy-absorption box welded plates, two described energy-absorption box welded plates are welded with energy-absorption box respectively, and the two ends of described crossbeam are welded on two energy-absorption boxes respectively; Described energy-absorption box welded plate is a few font, and energy-absorption box welded plate is provided with some through holes, by being bolted on vehicle body.
Preferably, described crossbeam is square hollow straight tube, and its cross-sectional plane is order font structure.
Preferably, the outer face of described crossbeam is provided with groove surface.
Preferably, described groove surface is made up of several oval-shaped grooves.
Preferably, described energy-absorption box is hollow tube, and its cross-sectional plane is square, just hexagonal or positive eight limit types.
Preferably, energy-absorbing muscle is provided with above all ribs of described energy-absorption box.
Preferably, described energy-absorbing muscle is a row, and it is arranged on the one end near energy-absorption box welded plate on energy-absorption box.
Preferably, described energy-absorbing muscle is two rows, is separately positioned on energy-absorption box near one end of energy-absorption box welded plate and the other end near crossbeam.
Have employed a few font welded plate in the utility model, can be good at playing energy-absorbing function.
On the outer face of crossbeam, be provided with groove surface in the utility model, the effect of buffering percussive force can be played.
Have employed energy-absorption box structure in the utility model, and the cross-sectional plane of energy-absorption box can be designed to some shapes, such as square, regular hexagon or octagon etc.Energy-absorbing muscle is provided with above the rib of energy-absorption box, when impact force is spent large time, can buffer portion impact.
Beneficial effect:
(1) have employed a few font welded plate in the utility model, on the outer face of crossbeam, be provided with groove surface, and have employed the energy-absorption box structure being provided with energy-absorbing muscle, when impact force is spent large time, good buffer action can be played, improve the overall performance of automobile.
(2) in high speed offset collision, impact on the left of vehicle body (or right side) can be delivered to right side (or left side) by actv. by anticollision device of the present utility model, allows whole car body go to absorb collision energy as far as possible.When there is low speed collision, collision prevention girders can avoid impact to the infringement before vehicle body, reduces maintenance cost.
