Therefore, the front cross member 20 and the first cavity 101 formed by the body 10 increase the deformation resistance of the top cover, i.e. improve the overall strength of the top cover.
With reference to fig. 4, in the present embodiment, the cross sections of the middle cross member 30 and the rear cross member 40 are "n" shaped, the inner walls of the middle cross member 30 and the rear cross member 40 both protrude towards the direction away from the inner wall of the body 10, the longitudinal front and rear ends of the middle cross member 30 and the rear cross member 40 both have flanges attached to the inner wall of the body 10, and the inner walls of the middle cross member 30 and the rear cross member 40 and a part of the inner wall of the body 10 both enclose a second cavity 102. The turned-over edges of the middle cross beam 30 and the rear cross beam 40 are fixedly connected with the body 10, the turned-over edges have a certain area, so that the fit parts between the middle cross beam 30 and the body 10 and between the rear cross beam 40 and the body 10 have a certain area, and the connection strength between the middle cross beam 30 and the body 10 and between the rear cross beam 40 and the body 10 is enhanced. And the flange itself also has a certain supporting function for the body 10. The second cavity 102 has a depth in the vertical direction, and the vertical direction has a large bending resistance, so that the second cavity 102 is not easily deformed and bent when being subjected to an external force. The second cavity 102 has a width in the horizontal direction, that is, the second cavity 102 has a larger thickness in the horizontal direction and a larger horizontal bending resistance, so that the second cavity 102 is not easily deformed and bent in the horizontal direction when an external force is applied.

With reference to fig. 5, in the present embodiment, the cross section of the longitudinal beam 50 is "n" shaped, the inner wall of the longitudinal beam 50 protrudes in a direction away from the inner wall of the body 10, both lateral ends of the longitudinal beam 50 have flanges attached to the inner wall of the body 10, and the inner wall of the longitudinal beam 50 and part of the inner wall of the body 10 enclose a third cavity 103. The flanging of the longitudinal beam 50 is fixedly connected with the body 10, and the flanging has a certain area, so that the joint part between the longitudinal beam 50 and the body 10 has a certain area, and the connection strength between the longitudinal beam 50 and the body 10 is enhanced. And the flange itself also has a certain supporting function for the body 10. The third cavity 103 has a depth in the vertical direction, and the vertical direction has a large bending resistance, so that the third cavity 103 is not easily deformed and bent when being subjected to an external force. The third cavity 103 has a width in the horizontal direction, that is, the third cavity 103 has a larger thickness in the horizontal direction and a larger horizontal bending resistance, and the third cavity 103 is not easily deformed in the horizontal direction when subjected to an external force. Therefore, the third cavity 103 formed by the longitudinal beam 50 and the body 10 increases the deformation resistance of the roof, i.e. improves the overall strength of the roof.
In this embodiment, the inner wall of the body 10 has a plurality of ribs 60 protruding outward in the longitudinal direction. Since the reinforcing ribs 60 protrude outward and have a depth in the vertical direction, that is, a thickness in the vertical direction of the reinforcing ribs 60, the bending resistance of the body 10 in the vertical direction can be increased, so that the body 10 is not easily bent when being subjected to a pressure in the vertical direction. Thus, the reinforcing ribs 60 increase the deformation resistance of the top cover, i.e., improve the overall strength of the top cover.
Further, at least one reinforcing rib 60 may be disposed opposite to the longitudinal beam 50, so that the depth of the formed third cavity 103 in the vertical direction is greater, and the deformation resistance of the third cavity 103 is further increased, that is, the overall strength of the roof is improved.

In order to mount the louver 80, the louver 80 needs to be opened in the projection 70. Of course, the roof may not have the louvers 80, because the louvers 80 may reduce the strength of the portion of the protrusion 70, and thus the roof without the louvers 80 may have higher strength as a whole.
In this embodiment, a portion of the body 10 adjacent to the front cross member 20 and disposed opposite to the front cross member 20 protrudes laterally toward both sides. Because this part body 10 is towards both sides protrusion, lead to the partial area in front of body 10 great, can increase the area of atress, reduce this part and receive the pressure intensity that produces behind the external force, be favorable to improving the bulk strength of top cap.

The proper width and depth can improve the strength of the top cover on the premise of reducing the material consumption as much as possible. In the embodiment, through simulation analysis, when the ratio of the width value to the depth value of the cross section of the cross beam is found to be in the range of 1:1-3:1, the middle cross beam 30 and the rear cross beam 40 with smaller sizes can be formed, so that the light weight is realized, meanwhile, the strength and the rigidity of the middle cross beam 30 and the rear cross beam 40 are also larger, and the strength of the top cover can be improved on the premise of reducing the material consumption as much as possible.
In this embodiment, the top cover body 10 is formed by integral deep drawing, which is a machining process for punching a flat blank of a certain shape obtained after blanking into various hollow parts with openings or reducing the diameter of the hollow blank with openings to increase the height. The top cover body 10 is formed by drawing, and has high overall strength.
