A double platform filling structure with double protection

Abstract

The invention discloses a double platform filling structure with double protection. The double platform filling structure with double protection comprises at least four microcells. Each microcell is formed by combining two symmetrical concave triangular cell bodies. Each concave triangular cell body comprises a first energy absorbing part and a second absorbing parts same in structure. The top ends of the first energy absorbing part and the second absorbing part are connected through a connecting block. The first energy absorbing part comprises an upper horizontal connecting part, a first energy absorbing portion, a second energy absorbing portion, a force transfer portion, a third energy absorbing portion and a lower horizontal connecting portion. The microcells are successively arrangedand combined in X direction and Y direction and an octagonal energy absorbing area is formed between adjacent two microcells. The filling structure can be used for achieving bidirectional protection functions of human and an automobile by means of the octagonal energy absorbing areas.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to a double-protection double-platform filling structure. Background technique [0002] Anti-collision beams, energy-absorbing boxes and front longitudinal beams constitute the main energy-absorbing components of the front end of the car; among them, the energy-absorbing box plays a vital role in low-speed collisions. In recent years, there have been many patents and academic research on the performance improvement of the energy-absorbing box, which can be roughly divided into two forms: one is to optimize the cross-sectional shape of the energy-absorbing box, and the other is to fill the energy-absorbing box with lightweight energy absorbing material. Chinese patent CN209079843U discloses "a new multi-section energy-absorbing box", which realizes the stability of the energy-absorbing process through the change of the section. Chinese patent CN109532730A discloses "a new type...

Problems solved by technology

[0003] The purpose of the present invention is to provide a dual-platform filling structure with double protection, to solve the problem that the filling structures in the existing energy-absorbing boxes are all one-way protection, when the collision form is between a person or a cyclist and a car In the case of two-way protection, it is impossible to achieve the technical problem of reducing the damage of the car and protecting the safety of people at the same time
