Threshold beam structure of fuel cell hydrogen energy automobile

Abstract

The invention relates to a threshold beam structure of a fuel cell hydrogen energy automobile. The threshold beam structure comprises a threshold beam and a hydrogen cylinder frame installation limiting plate. A cavity penetrating through the whole threshold beam is formed in the threshold beam, and a plurality of reinforcing ribs are arranged in the cavity. A mounting limiting groove is formed inthe lower end of the threshold beam; the hydrogen cylinder frame mounting installation plate is adaptively inserted into an installation limiting groove for fixed mounting. The section of the threshold beam structure is a closed cavity, and the reinforcing ribs are arranged in the cavity, so that the bending and torsional rigidity of a vehicle body can be effectively improved; compared with a traditional steel plate material, the threshold beam is made of an aluminum alloy material and has the advantages of light weight, simple manufacturing process, low mold investment cost, simple and reliable connection mode, good sealing and corrosion resistance and the like; the aluminum alloy threshold beam is of an integrally-formed structure, on the premise that various performance requirements ofa vehicle body are met, the welding and coating process is greatly simplified, the welding precision of the vehicle body is improved, the production efficiency is improved, and the die has left-rightuniversality; according to the threshold beam, the hydrogen cylinder frame mounting structure for the aluminum alloy section with the closed section is ingeniously designed.

Description

technical field [0001] The invention relates to the field of sill beam design, in particular to a sill beam structure for a fuel cell hydrogen energy vehicle. Background technique [0002] At present, the sill beam of the traditional sheet metal body is welded by inner and outer sill bodies, sill reinforcement plates, and side outer panels. The corrosion resistance is not good and the weight is heavy, which is not conducive to the lightweight of the whole vehicle, and has a particularly obvious impact on the battery life of new energy vehicles. The door sill beam of the aluminum profile structure described in this scheme can effectively improve the torsional and bending rigidity of the whole vehicle while achieving a substantial weight reduction and cost reduction of the vehicle body. Contents of the invention [0003] In order to solve the technical problems in the prior art, the present invention provides a fuel cell hydrogen energy vehicle threshold beam structure, inc...
