Vehicle lateral collision energy absorption structure

Abstract

The invention discloses a vehicle lateral collision energy absorption structure. A battery assembly framework is fixedly connected to the upper side of a vehicle framework. The two sides of the battery assembly framework are fixedly connected with energy absorption frameworks. Each energy absorption framework comprises an energy absorption supporting framework and energy absorption boxes, wherein the side, close to the battery assembly framework, of the energy absorption supporting framework is fixedly connected with the multiple energy absorption boxes. The energy absorption boxes are of a tubular structure, the cross section of each energy absorption box is of a rectangular cross section, a plurality of notches are formed in the edges of the rectangular structures, and the notches are triangular notches or circular arc notches or rectangular notches. One side of the battery assembly framework is fixedly connected with the energy absorption frameworks, the energy absorption frameworks comprise the energy absorption boxes and the energy absorption supporting frameworks for supporting the energy absorption boxes, the energy absorption boxes can buffer external collision force to protect the battery assembly framework, and furthermore, the safety of batteries and the physical safety of users on the battery assembly framework are ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle side door and door interior anti-collision energy-absorbing structure design, in particular to a vehicle side collision energy-absorbing structure. Background technique [0002] With the increase of vehicle penetration rate and the increase of vehicle types in the market, vehicle safety has become the top priority in the process of vehicle use. In the prior art, in order to improve the anti-collision ability of the side of the vehicle, usually high-strength steel stamping parts are used to strengthen the B-pillar, side sills and floor beams on the side of the vehicle to improve the anti-collision ability of the vehicle. This method improves the side collision avoidance capability of the vehicle to a certain extent, but the structure is complex and the manufacturing cost is high, so it is difficult to be implemented and applied in a low-cost vehicle frame structure body. [0003] It can be seen th...
