Anti-collision buffer strengthened structure of passenger car front wall

Abstract

The invention discloses an anti-collision buffer strengthened structure of a passenger car front wall. The anti-collision buffer strengthened structure of the passenger car front wall comprises a buffer unit, a strengthen unit and a connecting bracket, wherein the buffer unit comprises a buffer baffle and a corrugated plate, the buffer baffle and the corrugated plate are alternately arranged to form a multi-layer structure; the strengthen unit comprises a plurality of honeycomb plates, and the honeycomb plates are parallelly arranged at intervals and connected by an insertion structure in an inserted mode; and the connecting bracket comprises an upper connecting beam and a lower connecting beam, and is welded to the inner side of a bus front wall frame and used for fixedly connecting the honeycomb plates, and the buffer unit is located in front of the strengthen unit and welded to the strengthen unit through a plurality of springs. According to the anti-collision buffer strengthened structure of the bus front wall, collision energy can be quickly absorbed when a passenger car is in front collision, the deformation degree of the car body structure is lowered, and thus the safety performance of the passenger car can be improved.

Description

Technical field [0001] The invention relates to the field of passenger car manufacturing, in particular to a collision-proof buffer reinforcement structure for the front wall of a passenger car. Background technique [0002] With the rapid development of society, the development of public transportation is getting faster and faster. Passenger cars occupy a dominant position in urban public transportation. The safety issues that follow are also paid attention to, in order to reduce the fatality rate and the degree of damage to passenger cars in traffic accidents. , It also puts forward higher requirements on the structure of passenger cars. [0003] When a passenger car is in a frontal collision, the impact is large, and the car body is often severely deformed, which is very dangerous. Therefore, it is necessary to design a structure that can absorb energy and strengthen the front wall of the passenger car during a collision. Summary of the invention [0004] The object of the prese...
