[0034] LiDAR is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of a target. Through LiDAR, the car projects real-time information about the vehicle's condition onto the display screen inside the vehicle, which can display vehicles or pedestrians passing by the car, increasing the safety of the car during driving. LiDAR can also assist in parking, improving the user experience.

[0035] In the related art, for the same vehicle model, if there are two configurations, one equipped with a laser radar and the other not equipped with a laser radar, different top cover assemblies need to be designed and produced for the two configurations respectively, resulting in an increase in the cost of the top cover mold.

[0036] The main purpose of the present invention is to propose a laser radar mounting structure, a vehicle body and a vehicle, aiming to at least solve the technical problem in the related art that, for the same vehicle model, if there are two configurations, one equipped with a laser radar and one not equipped with a laser radar, different top cover assemblies need to be designed and produced respectively for these two configurations, resulting in an increase in the cost of the top cover mold.

[0037] See also Figure 1 and Figure 2 In one embodiment of the present invention, the laser radar mounting structure 100 includes a top cover assembly 1 and a mounting bracket 2, the top cover assembly 1 includes a top cover outer plate 11 and a top cover cross beam 12 arranged on the inner side of the top cover outer plate 11, and an avoidance hole 111 is opened on the top cover outer plate 11; the mounting bracket 2 is used for the installation of the laser radar body 6, the mounting bracket 2 is arranged on the top cover cross beam 12 and is arranged opposite to the avoidance hole 111; wherein, the avoidance hole 111 is used for the laser radar body 6 installed on the mounting bracket 2 to pass through.

[0038] In the technical solution of the present invention, the top cover assembly 1 includes a top cover outer panel 11 and a top cover cross beam 12 arranged on the inner side of the top cover outer panel 11, the top cover outer panel 11 is provided with an avoidance hole 111, the mounting bracket 2 is arranged on the top cover cross beam 12 and is arranged opposite to the avoidance hole 111; in this way, when the laser radar body 6 is installed, it is installed on the top cover cross beam 12 through the mounting bracket 2, and only one avoidance hole 111 is required on the top cover outer panel 11 for the laser radar to pass through. With such a configuration, for different configurations of the same vehicle model with or without a laser radar, the same set of injection molds can be used for production, and only an additional avoidance hole 111 needs to be provided on the top cover outer panel 11 after injection molding, which reduces the production cost.

[0039] There are many ways to reduce the amount of external impurities and rainwater entering the vehicle through the avoidance hole 111, such as sealing the mounting bracket 2 and the inner side of the top cover outer plate 11 to block the avoidance hole 111. In the embodiment of the present invention, please refer to Figure 1 and Figure 2 The laser radar installation structure 100 also includes a decorative cover 3 covering the outside of the top cover outer panel 11, and the decorative cover 3 covers the avoidance hole 111. In this way, the avoidance hole 111 is covered by the decorative cover 3, thereby reducing the possibility of external impurities and rainwater entering the interior of the vehicle through the avoidance hole 111. At the same time, the decorative cover 3 can also make the appearance of the top cover assembly 1 more beautiful, and play a certain protective role on the laser radar body 6 installed on the mounting bracket 2.

[0040] Of course, the decorative cover 3 is partially transparent so that the laser radar body 6 can emit and receive lasers.

[0041] It is understandable that for the aesthetics of the vehicle, the decorative cover 3 needs to be installed centrally on the top cover outer panel 11, and some installation methods, such as fixing by glue, are difficult to ensure the installation position of the decorative cover 3. In order to more conveniently install the decorative cover 3 on the top cover outer panel 11, in an embodiment of the present invention, the laser radar installation structure 100 also includes a positioning component 4, and the positioning component 4 includes a positioning portion and a positioning matching portion respectively arranged on the decorative cover 3 and the top cover outer panel 11; in this way, the decorative cover 3 can be positioned and installed on the outer side of the top cover outer panel 11 through the action of the positioning portion and the positioning matching portion, which makes the installation more convenient and can ensure the installation position of the decorative cover 3.

[0042] There are many forms of the positioning part and the positioning matching part. In an embodiment of the present invention, one of the positioning part and the positioning matching part is set as a positioning hole 41, and the other is set as a positioning column. The positioning hole 41 and the positioning column are snap-fitted. In this way, the top cover outer panel 11 and the decorative cover 3 can be quickly positioned by the matching method of the positioning column and the positioning hole 41. At the same time, the positioning column and the positioning hole 41 can clamp the top cover outer panel 11 and the decorative cover 3, and there is no need to fix the decorative cover 3 by other fixing methods such as glue. The forms of the positioning part and the positioning matching part are not limited to this. For example, in one embodiment, the positioning part and the positioning matching part can also be positioned by magnetic matching.

[0043] The positioning hole 41 can be set on the top cover outer panel 11, or on the decorative cover 3, and the positioning column is correspondingly set on the other one of the top cover outer panel 11 and the decorative cover 3. It can be understood that for a vehicle model that is not equipped with a laser radar, there is no need to set the positioning column on the top cover outer panel 11 to affect the appearance, so the positioning column is welded or bonded separately after the top cover outer panel 11 is injection molded, which will make the overall production process more troublesome. Therefore, in an embodiment of the present invention, the positioning hole 41 is set on the top cover outer panel 11, and the positioning column is set on the inner side of the decorative cover 3. In this way, the positioning column and the decorative cover 3 can be set by integral injection molding, and the positioning hole 41 can be opened together with the avoidance hole 111 after the injection molding of the top cover outer panel 11 is completed, so that the overall production process is simpler.

[0044] It can be understood that the top cover outer plate 11 is usually thin, and the provision of the avoidance hole 111 will result in poor local strength of the top cover outer plate 11. The top cover outer plate 11 may deform around the avoidance hole 111 due to the gravity of the decorative cover 3, resulting in sealing failure. Therefore, in the embodiment of the present invention, the decorative cover 3 is supported by the mounting bracket 2; thus, the decorative cover 3 is supported by the mounting bracket 2, so that the top cover cross beam 12 can share the pressure of the decorative cover 3 on the top cover outer plate 11, reducing the possibility of deformation of the outer edge of the top cover.

[0045] The roof outer panel 11 and the roof cross beam 12 may have tolerances during manufacturing, and this manufacturing tolerance may cause the mounting bracket 2 to fail to support the decorative cover 3, thereby increasing the possibility of deformation of the roof outer panel 11, and may also cause the gap between the roof outer panel 11 and the decorative cover 3 to be too large, resulting in sealing failure. In the embodiments of the present invention, please refer to Figure 3 and Figure 4, the thickness direction of the top cover outer panel 11 is the first direction; the laser radar mounting structure 100 also includes at least one adjusting member 5, the mounting bracket 2 is arranged on the top cover cross beam 12 through the adjusting member 5, and the adjusting member 5 is used to adjust the distance between the mounting bracket 2 and the top cover cross beam 12 in the first direction.

[0046] In the technical solution of this embodiment, during installation, the distance between the mounting bracket 2 and the cover plate can be adjusted. If the distance between the decorative cover 3 and the top cover outer panel 11 is too large, the distance between the top cover cross beam 12 and the mounting bracket 2 can be reduced by the adjusting member 5, so that the decorative cover 3 is supported on the mounting bracket 2 while the decorative cover 3 and the top cover outer panel 11 can also be sealed together, thereby reducing the possibility that the gap between the decorative cover 3 and the top cover outer panel 11 is too large to affect the sealing performance; if the decorative cover 3 is not well supported on the mounting bracket 2, the distance between the mounting bracket 2 and the top cover cross beam 12 can be increased by the adjusting member 5, so that the decorative cover 3 can be supported on the mounting bracket 2 while maintaining a sealed fit with the top cover outer panel 11, thereby reducing the possibility that the decorative cover 3 excessively compresses the top cover outer panel 11 and causes deformation. In summary, setting the mounting bracket 2 on the top cover cross beam 12 through the adjusting member 5 can effectively absorb the manufacturing tolerance between the top cover outer panel 11 and the top cover cross beam 12, thereby reducing the possibility that the gap between the decorative cover 3 and the top cover outer panel 11 is too large to affect the sealing performance, and also reduces the possibility that the decorative cover 3 excessively presses the top cover outer panel 11 and causes deformation of the top cover outer panel 11.

[0047] Of course, the method of absorbing the manufacturing tolerance between the roof outer panel 11 and the roof cross beam 12 is not limited to adjusting the distance between the mounting bracket 2 and the roof cross beam 12. In another embodiment, the mounting bracket 2 and the roof cross beam 12 remain fixed, and the decorative cover 3 can be supported on the mounting bracket 2 by a retractable structure, and the manufacturing tolerance between the roof outer panel 11 and the roof cross beam 12 is absorbed by adjusting the distance between the decorative cover 3 and the mounting bracket 2. However, in comparison, the mounting bracket 2 itself requires a mounting structure to be installed on the roof cross beam 12, and an additional retractable structure needs to be provided on the decorative cover 3, which makes the overall structure more complicated; in this embodiment, the mounting bracket 2 is directly installed on the roof cross beam 12 through the adjusting member 5, which makes the overall structure simpler.

[0048] The adjusting member 5 has various forms. In this embodiment, the adjusting member 5 includes an adjusting portion 51 and an adjusting matching portion 52 respectively arranged on the mounting bracket 2 and the roof cross beam 12. One of the adjusting portion 51 and the adjusting matching portion 52 can be rotatably arranged, and the adjusting portion 51 and the adjusting matching portion 52 are threadedly matched. In this embodiment, the adjusting member 5 adopts the form of threaded adjustment. During actual adjustment, only one of the adjusting portion 51 and the adjusting matching portion 52 needs to be rotated to change the size of the entire adjusting member 5 in the first direction, thereby adjusting the distance between the roof cross beam 12 and the mounting bracket 2. In another embodiment, the adjusting member 5 can be in the form of a hydraulic rod. The adjusting member 5 only needs to be able to adjust the distance between the roof cross beam 12 and the mounting bracket 2.

[0049] The present invention also proposes a vehicle body, which includes a laser radar installation structure 100 and a laser radar body 6. The specific structure of the laser radar installation structure 100 refers to the above embodiment. Since the vehicle body adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the laser radar body 6 is installed on the mounting bracket 2 and passes through the avoidance hole 111 to the outside of the top cover outer plate 11.

[0050] In the technical solution of the present invention, when the laser radar body 6 is installed, it is installed on the top cover cross beam 12 through the mounting bracket 2, and only one avoidance hole 111 needs to be opened on the top cover outer panel 11 for the laser radar to pass through. With such an arrangement, for different configurations of the same vehicle model with or without a laser radar, the same set of injection molds can be used for production, and only one additional avoidance hole 111 needs to be opened on the top cover outer panel 11 after injection molding, which reduces the production cost.

[0051] The present invention also proposes a vehicle, which includes a body. The specific structure of the body refers to the above-mentioned embodiments. Since the vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0052] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
