Embodiment Construction
[0023] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the following description is only illustrative and exemplary.
[0024] figure 1 A schematic diagram of an embodiment of a reinforcement structure for a vehicle body roof according to the invention is shown. It can be seen from the figure that in this embodiment, the structure of the vehicle body includes the roof middle beam 10, the front pillar 20, the center pillar 30, the rear pillar 40, the side wall (that is, the roof beam) 50 and the floor beam 60, etc. Together with other columns, beams and other structures, they form the car body. The structure of the roof of the car body includes the middle beam 10 of the roof, the front pillar 20, the center pillar 30, the rear pillar 40 and the side wall 50, etc.; The side circumference is 50. The middle beam 10 crosses the roof of the vehicle along the width direction o...

The invention relates to a reinforcing structure of an automobile body top cover and an automobile with the reinforcing structure. The reinforcing structure comprises a middle transverse beam of the automobile body top cover and an enclosure of an automobile body, wherein the middle transverse beam goes across the automobile body top cover in the width direction of the automobile body top cover, the two ends of the middle transverse beam are respectively and fixedly connected with the enclosure of the automobile body, the cross section of the middle transverse beam at any position is a sealed cross section, and the connecting surface of the connecting part of the middle transverse beam and the enclosure of the automobile body is also provided with the sealed cross section. The automobile and the reinforcing structure of the automobile body top cover have the advantages that the side impact performance is better than the side impact performance in the linear transverse beam cross section design and connecting design of the prior art, so the lateral load transfer capability of the automobile body is effectively improved by the reinforcing structure; and meanwhile, the structure is simple, and the manufacturing cost is low.
Description
technical field [0001] The invention relates to the structural design of the automobile body; in particular, the invention relates to a reinforcement structure of the roof of the automobile body. [0002] Furthermore, the present invention also relates to an automobile comprising such a reinforcing structure. Background technique [0003] With the improvement of people's living standards, the application of small cars has gradually entered thousands of households; because of this, people's requirements for car safety are also getting higher and higher. The design of the pillars and beams of the automobile body is an important index affecting the safety of the automobile when it collides. For example, in a side collision, the connection structure between the middle beam and the side wall of the car body roof plays an important role in load transmission, and its design and manufacture are also particularly important. [0004] In the vehicle models of the prior art, the midd...
