Above-mentioned head-on crash device, its characteristics are that described big energy-absorbing box is or/and described little energy-absorbing box is provided with the weakening processing part that is used to produce the axial compression degeneration.
Above-mentioned head-on crash device, its characteristics be, described local weakness handling part be arranged on described energy-absorbing box to the depressed part on beam and the web.
Above-mentioned head-on crash device, its characteristics are that described big energy-absorbing box port is provided with connecting panel and the supporting plate that has mounting hole, and described connecting panel is fixedly connected on the crossbeam of described front side member.
Above-mentioned head-on crash device, its characteristics be, the girder reinforcement is set below the longeron cover plate of described front side member, and/or in described front fork beam trough girder the front fork reinforcement is set.
By increasing crash energy absorption equipment at body forward structure, make the axial compression rigidity of this device will be lower than the axial compression rigidity of front side member, and its rigidity when being provided with crumple, this to have metastable numerical value, prevent sharply the descend appearance of situation of its rigidity; On this basis, in front side member and body forward structure crash energy absorption equipment to the processing that weakens accordingly of beam and web, the portion's of keeping away depression guiding longeron and the anterior crash energy absorption equipment generation of car axial compression degeneration, thus improve the energy-absorbing level of whole device.Simultaneously, vehicle front side member and girder and trinary beam root are strengthened, the front side member that make of reinforcement has enough bending stiffnesies and enough axial pressure rigidity, with the flexural deformation and the axial crushing deformation of control front side member.
By adopting said structure, make the tack Light-duty Vehicle in anti-the bumping property of structure with aspect occupant's protection, all have outstanding performance.
Further specify specific embodiment of the utility model below in conjunction with accompanying drawing.
