At present, with the continuous development of new energy automobiles, hydrogen energy automobiles gradually become an important choice, and because the lightweight requirements of automobiles are higher and higher, aluminum alloy becomes a mainstream structural material and a main body bearing structure, but aluminum material has higher cost, and the weight is reduced and the cost is reduced as much as possible on the basis of ensuring the performance.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a hydrogen energy vapour car roof beam structure adopts section bar lip limit overlap joint at non-main load position to reduce weight and reduce cost.
The utility model provides a hydrogen energy automobile top cover beam structure, which comprises a beam body, wherein the beam body is arranged below the joint of an automobile body top cover and windshield glass;
the beam body comprises an upper surface and a lower surface, the upper surface and the lower surface form a cavity, and one end of the upper surface extends outwards to form a lip edge; the cavity is fixedly connected with the top cover of the vehicle body through first glass cement, and one side, close to the cavity, of the lip edge is fixedly connected with the windshield glass through second glass cement.
Further, the lower surface is composed of a vertical section, a horizontal section and a broken line section, a cavity formed by the lower surface and the upper surface is an inverted trapezoidal cavity, and the connection position of the upper surface and the broken line section of the lower surface extends outwards to form the lip edge.
Furthermore, the vehicle body top cover and the windshield glass are in interference sealing through a top cover rubber strip and a windshield rubber strip, and the lower edges of the top cover rubber strip and the windshield rubber strip are in lap joint with each other and are in interference sealing on the upper surface of the cross beam body.
Furthermore, the left end and the right end of the lip edge are respectively provided with a windshield positioning hole, and windshield positioning pins on the left side and the right side of the windshield glass are arranged in the windshield positioning holes.
The utility model also provides a hydrogen energy car, including above-mentioned hydrogen energy vapour car roof beam structure.
The utility model provides a beneficial effect that technical scheme brought is: the glue spreading and main bearing surface are lapped by a cavity, and the non-main bearing part is lapped by a lip edge to replace the traditional complete square cavity, thereby reducing the weight of the vehicle body and the cost.
