Multilayer buffering guiding car front bumper structure

Abstract

The invention discloses a multilayer buffering guiding car front bumper structure. The multilayer buffering guiding car front bumper structure sequentially comprises an outer frame, a first baffle, a wire net layer, locking blocks, a folding plate group and a main anti-collision beam from outerside to inside of a car body; the first baffle is closely connected to the inner side of the outer frame, the outer frame and the first baffle are bent together towards the inner side to form a section, the wire net layer is in intersected connection to the inner side of the first baffle at intervals, each section of the wire net layer is a wire net section, and the locking blocks are connected to the gap between every two adjacent wire net sections and the inner end of wire net layer through bolts; and the folding plate group comprises a plurality of sections of folding plates which are connected together, the folding plates are mutually connected to form a grid shape, connecting parts are formed in the position, on one sides of the locking blocks of the folding plate group, end parts are formed in the position, on one side of the main anti-collision beam, of the folding plate group, and the connecting parts and the end parts are correspondingly connected with the locking blocks and the main anti-collision beam. According to the multilayer buffering guiding car front bumper structure, all parts are interlocked, the maximized buffering and anti-collision effect can be achieved, the passive safety performance of a car front bumper is improved greatly, and unification of simplifying and high efficiency of structural design is achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a multi-layer buffer guide automobile front bumper structure. Background technique [0002] With the development of the automobile industry, the automobile bumper, as an important safety device, is also on the road of innovation. It is true that integrated steel or aluminum alloy bumpers have better safety performance for cars, but they are more harmful to pedestrians. Therefore, in addition to maintaining the original protection function, the current automobile bumper must also pursue harmony and unity with the body shape, pursue its own lightweight; use composite materials to expand application performance. [0003] The front end of the car includes structural components such as the front end shell and the anti-collision beam. In order to take into account the elegant decoration and the passive safety performance of collapse energy absorption, a multi-layer struc...

AI Technical Summary

Problems solved by technology

There is no buffer structure between the traditional car bumper and the body, and the impact toughness and mechanical structure have no buffer and insurance effect on the car body. Therefore, it is necessary to comprehensively improve the structure of the car bumper to meet the safety needs of the new situation.
