Description
Technical field
The present invention relates to the bumper in a kind of automobile component, is propped up in particular to a kind of elasticity of bumper
Support arrangement and bumper.
Background technology
With the continuous progress of automotive engineering, people pay attention to injury problem of the vehicle to pedestrian more and more.Among these,
The injury of automobile bumper structure and installation form and pedestrian are in close relations, and automobile bumper mounting structure is really up to the mark, can cause to go
The fractured leg or ligament of people is broken, but vehicle is durable and reliability demand fender-guard mounting structure can not be excessively weak again.Therefore, OK
People's protective value and Automobile structure design certain contradiction be present, it is necessary to which automotive development person carries out lasting research.
Current automobile bumper structure, when shank collides, shank first bumps against grid, and its bridging arrangement can be extruded into raised knot
The front end of structure, the rigidity of structure is very big herein, deforms very little, causes the moment of flexure injury of the shin bone acceleration and shank of shank very big.
For the impact problem of bumper, Chinese patent 201521097674.4 proposes a kind of prestressing force car insurance
Thick stick, its by set the first elastic stretching part by the fore shell two of bumper it is lateral among stretch so that among it forward end and
Rear end deformation protrudes, and so as to provide a kind of prestressing force, is stretched the side shell of bumper to centre by the second elastic stretching part, from
And in-between forward end deformation is protruded, so as to provide a kind of prestressing force, when colliding, prestressing force can offsets one
Divide impact, so as to improve the power that bumper can bear.First elastic stretching part and the second elastic stretching part constitute it
Interior resilient supporting unit, the first elastic stretching part and the second elastic stretching part are all specifically by pull bar and elastic supporting member for supporting optical member structure
Into.The shortcomings that resilient supporting unit disclosed in the patent, essentially consists in：1) structure is complex, can cause manufacturing cost
Rise；2) horizontal space shared by pull bar is larger, can occupy most horizontal space in bumper, easily cause bumper portion
The increase of partial volume.
The content of the invention
