DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] With the rapid development of smart electric vehicles, in order to provide customers with a better driving experience, more possibilities can be given to vehicles, such as autonomous driving. Technologies such as autonomous driving require vehicles to be equipped with lidar, and use lidar to perceive the surrounding environment in order to avoid obstacles and adjust the driving route.

[0031] In the related technology, when assembling a vehicle, the top cover exterior panel is usually installed on the body first, and then the laser radar is installed on the vehicle. This production method is time-consuming and labor-intensive, and seriously affects the progress of assembly on the vehicle production line.

[0032] In view of this, if Figures 1 to 5 As shown, the embodiment of the present application provides a vehicle assembly method, comprising the following steps: S1, a first workstation is provided on an assembly branch line, and a laser radar body 1 and a laser radar bracket 2 are placed on a top cover outer panel 3 at the first workstation, and an external mechanical component connects the laser radar body 1, the laser radar bracket 2 and the top cover outer panel 3 together through a second fastener. The laser radar body 1 and the laser radar bracket 2 are placed on the top cover outer panel 3, and the laser radar bracket 2 and the laser radar body 1 are installed together on the assembly branch line to form a laser radar module, and the second fastener includes a second bolt 53 and a third bolt 54, as shown in FIG. Figure 1 and Figure 3As shown, the second bolt 53 is quickly passed through the laser radar body 1 and the laser radar bracket 2 by the machine on the production branch line on the assembly branch line to connect the two together, and the laser radar bracket 2, the laser radar body 1 and the top cover exterior panel 3 are assembled together on the assembly branch line to form a radar decorative panel module, and the third bolt 54 is quickly passed through the laser radar bracket 2 and the top cover exterior panel 3 by the machine on the production branch line on the assembly branch line to connect the two together.

[0033] S2, assemble the top cover outer panel 3 and the vehicle body top cover cross beam 4 together on the main assembly line, that is, the top cover outer panel 3 with the laser radar module installed is a whole (radar decorative panel module), and an assembly station is provided on the main line of the vehicle production line, and the radar decorative panel module is installed on the vehicle body top cover cross beam 4 as a whole at the assembly station. It can save installation time on the production line, the whole assembly process is fast, and it is suitable for vehicle production lines for batch assembly, improving production efficiency and saving production time.

[0034] like Figure 1 and Figure 2 As shown, considering the convenience and sealing performance when assembling the laser radar bracket 2 and the vehicle body roof cover cross beam 4, in some embodiments, in step S2, the laser radar bracket 2 has a first surface 23 and a second surface 24 relative to each other, and the first surface 23 faces the roof exterior panel 3. The first nut 52 is first bonded to the first surface 23. After the first nut 52 is bonded to the laser radar bracket 2, the sealing performance is good. Then, the roof exterior panel 3 and the laser radar bracket 2 are assembled together to form a radar decorative panel module. Finally, the second surface 24 is attached to the vehicle body roof cover cross beam 4. The first bolt 51 passes through the first surface 23 from the second surface 24 and is threadedly connected to the first bolt 51 to fix the laser radar bracket 2 to the vehicle body roof cover cross beam 4. Because it is difficult to connect the first nut 52 with the first bolt 51 between the first surface 23 and the top cover outer panel 3 after the top cover outer panel 3 and the laser radar bracket 2 are assembled together, the first nut 52 needs to be bonded to the corresponding position before the top cover outer panel 3 and the laser radar bracket 2 are assembled together to form the radar decorative panel module. This can not only realize the fixed connection between the laser radar bracket 2 and the vehicle body top cover cross beam 4, but also increase the sealing between the laser radar bracket 2 and the vehicle body top cover cross beam 4, and prevent rainwater and other liquids on the first surface 23 of the laser radar bracket 2 from entering the second surface 24 through the thread gap and flowing into the vehicle.

[0035] Another embodiment of the present application provides a laser radar integrated installation structure, including a laser radar body 1, a laser radar bracket 2 and a top cover outer panel 3, wherein the laser radar body 1 is fixedly connected to the laser radar bracket 2 to form a laser radar module, such as Figures 1 to 3As shown, the laser radar body 1 and the laser radar bracket 2 are connected together by a second bolt 53 to form a laser radar module, and the laser radar bracket 2 of the laser radar module and the top cover exterior panel 3 are connected together by a third bolt 54 to form a radar exterior panel module. The radar exterior panel module is used to be assembled with the vehicle body top cover crossbeam 4 on the vehicle production line.

[0036] The top cover exterior panel 3 with the laser radar module installed is a whole (radar decorative panel module). An assembly station is provided on the main line of the vehicle production line, and the radar decorative panel module is installed as a whole on the vehicle body top cover cross beam 4 at the assembly station. It can save installation time on the production line, the whole assembly process is fast, and it is suitable for vehicle production lines for batch assembly, improving production efficiency and saving production time.

[0037] In some embodiments, the roof outer panel 3 and the vehicle body roof cross beam 4 are stacked and a first recess 31 is formed on the connection surface of the roof outer panel 3 facing the vehicle body roof cross beam 4, which is recessed away from the vehicle body roof cross beam 4. Part of the laser radar module is located in the first recess 31, and the laser radar bracket 2 is fixedly connected to the roof outer panel 3. Figure 4 As shown, the side wall of the first recess 31 covers the laser radar module to protect it and prevent branches or sand from scratching the laser radar body 1. An opening 32 is provided on the first recess 31. The transmitting part of the laser radar body 1 is aligned with the opening 32, and the laser emitted / received by the transmitting part is emitted / injected into the opening 32.

[0038] In some embodiments, a plurality of connection portions 311 are formed on the side wall of the first recess 31, and the laser radar bracket 2 includes an intersecting horizontal plate 21 and a vertical plate 22, the horizontal plate 21 is connected to the laser radar body 1, and one end of the horizontal plate 21 away from the vertical plate 22 is connected to a partial connection portion 311, and the vertical plate 22 is connected to another partial connection portion 311. Because the side wall of the first recess 31 is arc-shaped and has an inclined wall surface, and the laser radar bracket 2 is a plate-like structure, the gap between the laser radar bracket 2 and the side wall of the first recess 31 is large and the gap distance is unequal. A plurality of connecting parts 311 are formed on the side of the side wall of the first recess 31 facing the laser radar bracket 2. The vertical plate 22 is located on the side with a larger gap between the laser radar bracket 2 and the side wall of the first recess 31. The vertical plate 22 and the connecting part 311 are connected together by a second bolt 53. The total width of the vertical plate 22 and the connecting part 311 is just equal to the gap at this position. After the vertical plate 22 is connected to the connecting part 311, the horizontal plate 21 will not bend due to the connection tension between the laser radar bracket 2 and the side wall of the first recess 31, and the laser radar body 1 will not be squeezed.

[0039] In some embodiments, a second recess 41 is formed on the mounting surface of the vehicle body roof cross beam 4 facing the roof exterior panel 3, which is recessed away from the roof exterior panel 3. Another part of the laser radar module is located in the second recess 41. The first recess 31 and the second recess 41 are enclosed to form a housing cavity for accommodating the laser radar module. Figure 4 As shown, the top cover exterior panel 3 is adjacent to the front windshield 6 and is distributed on the vehicle. The bottom surface of the second recess 41 is an inclined surface and is inclined downward toward the front of the vehicle. Rainwater and other liquids entering from the opening 32 on the side wall of the first recess 31 easily fall on the first surface 23 of the laser radar bracket 2. The laser radar bracket 2 is attached to the bottom surface of the second recess 41. The bottom surface of the second recess 41 is an inclined surface and is inclined downward toward the front of the vehicle. Rainwater and other liquids on the first surface 23 of the laser radar bracket 2 will flow along the bottom surface of the second recess 41 and be discharged from the vehicle.

[0040] In some embodiments, a gap is provided between the body roof cross beam 4 facing the front side of the vehicle and the roof outer trim panel 3 facing the front side of the vehicle, and liquid falling on the bottom surface of the second recess 41 can flow out through the gap. The gap just corresponds to the front windshield 6, and liquids such as rainwater can flow out through the gap into the drainage groove on the front windshield 6 and then be discharged.

[0041] In some embodiments, the laser radar bracket 2 is connected to the vehicle body roof cover cross beam 4 through a first fastener, and the first fastener includes a first bolt 51 and a first nut 52. The first bolt 51 passes through the vehicle body roof cover cross beam 4 and the laser radar bracket 2 and is connected to the first nut 52. The first nut 52 abuts against one end of the laser radar bracket 2 and extends radially to form a sealing edge. The sealing edge is bonded to the laser radar bracket 2 by sealant to prevent rainwater and other liquids on the laser radar bracket 2 from flowing into the vehicle through the threaded gap.

[0042] In some embodiments, a sealing gasket is provided between the first bolt 51 and the vehicle body roof cover cross beam 4, and the sealing gasket is clamped between the first bolt 51 and the vehicle body roof cover cross beam 4, further improving the sealing performance between the vehicle body roof cover cross beam 4 and the laser radar bracket 2, and preventing rainwater and other liquids on the laser radar bracket 2 from flowing into the vehicle through the threaded gap.
