[0018] ​The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The terms "first" and "second" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise expressly specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

[0020] like Figure 1 and Figure 2 As shown, this application provides a vehicle body 10 for a vehicle equipped with a sunroof. The vehicle body 10 includes a top side beam 100, a crossbeam 200, and a connecting member 300. Along the vehicle's length direction x1, the crossbeam 200 has a first width; along the vehicle's length direction x1, the connecting member 300 has a second width, which is smaller than the first width. The connecting member 300 includes a first connecting end 310 and a second connecting end 320 disposed opposite each other along the vehicle's width direction x2. The first connecting end 310 is welded to the top side beam 100. The end of the crossbeam 200 is provided with a first connecting portion 210 adapted to the second connecting end 320, and the first connecting portion 210 overlaps the second connecting end 320 along the vehicle's height direction x3.

[0021] Specifically, existing vehicles equipped with sunroofs include models with and without a ceiling-mounted screen. The crossbeam 200 is a structural component providing stability support for the roof structure of the vehicle body 10. It possesses high structural strength; therefore, in vehicles equipped with a ceiling-mounted screen, the crossbeam 200 typically also serves as a structural support for connecting the ceiling-mounted screen. The first width is the minimum width required for the crossbeam 200 when a ceiling-mounted screen is installed, and the second width is the minimum width required for the crossbeam 200 to achieve optimal light transmission in the sunroof when no ceiling-mounted screen is installed. The crossbeam 200 with the first width is also called a wide crossbeam, and the corresponding overlapping piece 300 with the first width is a wide beam connector that matches the wide crossbeam. The crossbeam 200 with the second width is also called a narrow crossbeam, and the corresponding overlapping piece 300 with the second width is a narrow beam connector that matches the narrow crossbeam.

[0022] In the vehicle configured with the ceiling screen, the width of the wide cross beam is wide, and if not differentiated, the width of the cross beam 200 of the vehicle without the ceiling screen is also made wide, which will sacrifice the light transmission area of the sunroof of the vehicle without the ceiling screen, thereby affecting the user's vehicle experience. Therefore, in the prior art, the cross beam 200 and the lap joint 300 are usually matched parts, in other words, the wide cross beam is matched with the wide beam joint, and the narrow cross beam is matched with the narrow beam joint, which leads to a large difficulty in adapting the vehicle body 10 to different vehicle models, thereby increasing the development and production cost of the vehicle. In other words, in the manufacturing process, the lap joint 300 is part of the side wall assembly of the vehicle body 10, and the lap joint 300 needs to be welded to the top side beam in the manufacturing process of the side wall assembly. Therefore, if the cross beam 200 and the lap joint 300 are used as matched parts, the side wall assembly of the vehicle model with different configurations (such as the vehicle model configured with the ceiling screen and the vehicle model without the ceiling screen) cannot be shared. When the vehicle body 10 is adapted to the corresponding vehicle model, not only the side wall assembly needs to be optimized and adapted, but also the cross beam 200 needs to be optimized and adapted, which not only increases the difficulty of adapting the vehicle body 10 to different vehicle models, but also increases the development and production cost of the vehicle.

[0023] Unlike the prior art, as shown in Figure 1 and Figure 2 in the embodiment, the cross beam 200 is a wide cross beam, the lap joint 300 is a narrow beam joint, and the end of the cross beam 200 is provided with a first connecting part 210 adapted to the second connecting end 320 of the lap joint 300, so that the cross beam 200 can be connected to the lap joint 300 through the first connecting part 210, thereby meeting the connection requirement of the cross beam 200 and the top side beam 100, and effectively reducing the difficulty of adapting the vehicle body 10 to different vehicle models, thereby effectively reducing the development and production cost of the vehicle. In other words, in the embodiment, by configuring the first connecting part 210 adapted to the lap joint 300 at the end of the cross beam 200, the cross beam 200 can be connected to the top side beam 100 through the lap joint 300, so that the cross beam 200 can be used as a replacement part, and the lap joint 300 can be used as a universal part. When the vehicle body 10 is adapted to the vehicle model without the ceiling screen, only the wide cross beam needs to be replaced with the narrow cross beam, so that the vehicle body 10 can be adapted to the vehicle model without the ceiling screen, thereby effectively reducing the difficulty of adapting the vehicle body 10 to different vehicle models, and further effectively reducing the development and production cost of the vehicle.

The second connecting end 320 is connected with the first flat part 201, the second flat part 202 and the third flat part 203 respectively to realize the connection with the first connecting part 210.
