Abstract
The utility model provides a relate to the automobile manufacturing field, concretely relates to automotive anti -collision beam. It has solved the lower problem of current automotive anti -collision beam performance. This automotive anti -collision beam includes crashproof roof beam main part and mount pad, and crashproof roof beam main part is equipped with elastic construction and supporting fixing plate, and the elastic construction is combined closely with supporting fixing plate's, and the supporting fixing plate both ends are connected on the mount pad. The car upon impact, through top layer on with energy transfer to elastic construction, the supporting part of elastic construction is energy buffering, reduces the speed of energy transfer, compresses behind the cavity atress that elastic construction and supporting fixing plate formed, and with the air lock extrusion, gas speedily flows, and the energy reduces thereupon to the crashproof ability of car has been improved. In addition, the elastic construction can be through the crashproof requirement of deformation in order to satisfy different model cars, and the commonality is good.
Description
Technical field
This utility model is related to automobile manufacturing field and in particular to a kind of automobile buffer beam.
Background technology
Automobile uses and increasingly popularizes as a kind of transport and walking-replacing tool, but following vehicle accident is also gradually increasing
Plus, it is one of important quality index of Hyundai Motor that security performance has become as.How in collision scenario accident, maximum
The damage that is safe, reducing automobile vitals of limit ground protection occupant becomes the direction that each auto vendor makes great efforts.Low speed collision
Regulation is even more to auto-safety mechanism, and particularly collision prevention girders propose tightened up requirement.When automobile occurs positive collision, close
The front anti-collision beam structure of reason can reduce enging cabin and occupant area is impaired, also can reduce the caused body structure of collision and damage
Bad, reduce insurance premium.The collision prevention girders of automobile play the effect of protection automotive safety, and when automobile has an accident, collision prevention girders to the greatest extent may be used
Collision energy can be absorbed, reduce the extent of damage of vehicle body main body, to reduce the safety of maintenance cost and protection rider.
Automobile buffer beam is arranged on automotive front end for buffering the anterior infringement clashed into and vehicle body is caused, and then protects driving
Member and the personal safety of passenger.The two ends of existing collision prevention girders are connected with the longeron of car body both sides respectively, work as collision scenario
When, impact force is delivered on longeron after the buffering of collision prevention girders, makes longeron that collapse energy-absorption to occur, and then plays anticollision effect.
But, in actual head-on crash accident, automobile longitudinal girder and knocked object, all in certain angle of inclination, lead to longeron sending out
Certain flexural deformation is also had, thus reducing the energy-absorbing effect of longeron while raw crumple.
Content of the invention
For solving problem above, this utility model provides a kind of automobile buffer beam, and energy can be discharged by it, and reduction is touched
Hit the transmission of energy, thus reaching the dual-use function of protection vehicle and member.
The purpose of this utility model is achieved through the following technical solutions：A kind of automobile buffer beam, including arch collision prevention girders
Main body and mounting seat, described arch collision prevention girders main body include elastic construction and support fixed plate, support fixed plate edge with
Elastic construction connects formation cavity, and described support fixed plate two ends are fixed in mounting seat, and described support fixed plate includes side plate
And the base plate being connected with side plate, described base plate is provided with several bleeder ports, described elastic construction be provided with stress surface, bending section and
Junction surface.
As further scheme of the present utility model, described pore is provided with vent plug.
As further scheme of the present utility model, described side plate is closely connected with junction surface.
As further scheme of the present utility model, described support fixed plate is provided with charging valve.
As further scheme of the present utility model, described side plate is provided with lobe.
As further scheme of the present utility model, the face that described side plate is connected with joint portion is hair side.
Compared with prior art, the beneficial effects of the utility model are：When vehicle collides, elastic construction and support
Fixed plate combines setting and plays buffering and the effect releasing energy.After being blocked pore with vent plug, by charging valve to bullet
Property structure, support the cavity inflation that fixed plate formed, bend after the bending section stress of collision rift elastic construction, cavity pressed
Contracting, the energy of buffering collision.When cavity internal gas pressure reaches certain pressure value, vent plug is gone out, and gas is gone out from pore, will simultaneously
Energy discharges, and further increases the performance of cushion bumper.In addition collision prevention girders body setting domed, when car longeron with hit thing
When body is all in certain angle of inclination, elastic construction still can produce deformation, compaction cavum, buffers energy.When cavity compression
To a certain degree when vent plug also can go out, energy is gone out and is discharged with vent plug and gas, reduces collision to greatest extent right
The damage of automobile and the injury of personnel.
Additionally, elastic construction can produce deformation in order to meet the installation of different model automobile, versatility is good.And in vapour
Car not head-on crash when, elastic construction still can complete described process, also solve common collision prevention girders non-frontal collide
Collision prevention girders are led to fracture and ineffective problem.
