Problems solved by technology

[0002] At present, the top edge beam of the traditional sheet metal body is welded by parts such as the inner side wall, the outer plate and the inner reinforcement plate. The mold structure of this structural part is complex, the cost is high, the welding and coating process is complicated, and the sealing and corrosion resistance is not good. Well, the weight is heavy, which is not conducive to the lightweight of the whole vehicle, and the impact on the battery life of new energy vehicles is particularly obvious

Abstract

The invention provides a top edge beam structure of a fuel cell hydrogen energy automobile. The top edge beam structure comprises a top edge beam, a top edge beam protection plate and a top cover; a seam allowance part is arranged at the upper part of the top edge beam; a bending part matched with the seam allowance part in shape is arranged at one end, connected with the top cover, of the top edge beam protection plate; the end face of the inner side of the bending part and the seam allowance part are bonded in a sealed mode through a sealing rubber strip, and the waterproof effect is achieved; a sealing strip is arranged between the outer side end surface of the bending part and the top cover, so that a waterproof effect is achieved; the interior of the top edge beam is hollow, a plurality of reinforcing ribs are arranged in a hollow cavity of the top edge beam, and the purpose of improving the bending and torsional rigidity of a vehicle body is achieved. The invention has the beneficial effects that the torsion and bending rigidity of a whole vehicle is effectively improved while the weight of the vehicle body is greatly reduced and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a roof side beam structure of a fuel cell hydrogen energy vehicle. Background technique [0002] At present, the top edge beam of the traditional sheet metal body is welded by parts such as the inner side wall, the outer plate and the inner reinforcement plate. The mold structure of this structural part is complex, the cost is high, the welding and coating process is complicated, and the sealing and corrosion resistance is not good. Well, the heavy weight is not conducive to the lightweight of the whole vehicle, and the impact on the battery life of new energy vehicles is particularly obvious. Contents of the invention [0003] In order to solve the above problems, the present invention provides a roof side beam structure of a fuel cell hydrogen energy vehicle, which is made of aluminum alloy and has an integrally formed structure, which can effectively improve the ...
