Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and more specifically, to a radar assembly, a vehicle body assembly and a vehicle. Background Art

[0002] With the development of intelligent driving technology, as one of the key sensors, the performance and integration method of lidar are crucial to the overall efficiency of the system. Currently, lidars on the market are mainly divided into standard products and customized development products. Due to the high cost of customized development, commonly used lidars are mostly standard products, and these products usually do not have a sealing structure.

[0003] In vehicle integration, lidars are often arranged on the roof of the vehicle. This not only makes it difficult to integrate with the body shape in terms of appearance design, but also in a high-temperature environment, the long-term high-temperature operation of the lidar may cause a high-temperature alarm, which in turn affects the normal operation of the entire intelligent driving system. To solve this problem, the industry has proposed a solution to partially sink the lidar inside the vehicle body and use the temperature inside the cockpit to assist in heat dissipation to maintain the efficient operation of the lidar.

[0004] Lidar manufacturers usually offer standard products and customized development products. Considering that some manufacturers often arrange lidars on the roof, in order to simplify the design, the manufacturer may provide a customized sealed housing. However, the standard product itself does not have a sealing structure, and when considering partially sinking it inside the vehicle cabin, the sealing problem becomes a technical challenge.

[0005] To reduce the installation difficulty, many intelligent driving companies choose to arrange standard lidars on the roof without sealing treatment. Although this design simplifies the installation process, the integration degree of the lidar and the vehicle body is poor, and it looks obtrusive in appearance. To improve the heat dissipation problem of the radar, some solutions use thick aluminum plates and other materials for heat conduction and dissipation, but this increases the weight of the roof, which is not friendly to the vehicle shape and the heat dissipation effect of the lidar. In addition, the increase in the weight of the roof kit also requires an increase in the fixing and supporting strength to meet the requirements of complex road conditions.

[0006] In summary, there are certain limitations in the roof integration, sealing, and heat dissipation of lidars in vehicles in the prior art, and further technical improvements and innovative solutions are needed to improve the performance and reliability of the intelligent driving system.

[0044] Specifically, the lidar 2 is connected to the housing 1 through multiple fasteners. The inside of the wire-passing rubber sleeve 3 is filled with waterproof sealant to ensure the sealing of the connection wire.

[0045] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the housing 1 includes: a first housing 110 and a second housing 120. The first housing 110 is located on the side of the second housing 120 away from the vehicle body to jointly enclose an installation cavity 11. Among them, an opening 12 and an adhesive application groove 14 are located on the first housing 110, and a wire-passing hole 13 is located on the second housing 120.

[0046] As Figure 7 shown, multiple first cylinders 116 are provided on the first housing 110, and fastener threaded holes are provided on each of the first cylinders 116.

[0051] As Figures 7 to 9As shown, the first housing 110 includes: a first main board body 111 for contacting the vehicle body, and a first through hole is provided on the first main board body 111; a top plate 112 disposed at the first through hole, a first side of the top plate 112 near the rear of the vehicle body is connected to the first main board body 111, and a second side of the top plate 112 near the front of the vehicle body and a third side and a fourth side of the top plate 112 spaced apart in the width direction of the vehicle body are all spaced apart from the first main board body 111 to form an accommodation space; a first side plate 113 disposed at the accommodation space and connected to both the top plate 112 and the first main board body 111; wherein, the shape of the lower surface of the first main board body 111 matches the shape of the outer surface of the vehicle body, an opening 12 is provided on the first side plate 113, and an adhesive application groove 14 is located on the first main board body 111.

[0052] Wherein, the shape of the lower surface of the first main board body 111 is a curved surface that matches the shape of the upper surface of the top of the vehicle body. The first main board body 111 includes a first plate segment and a second plate segment connected to each other. The first plate segment is used for being installed in contact with the top of the vehicle body, and the second plate segment is used for being in contact with the upper part of the installation frame of the front windshield of the vehicle body, so that the entire radar assembly is located at a relatively low position at the top of the vehicle body, reducing the installation height of the lidar 2, and thus reducing the height of the highest point of the vehicle equipped with the radar assembly.

[0053] Specifically, each first cylinder 116 is located on the top plate 112 and on the side of the top plate 112 near the vehicle body.

[0054] As Figures 10 to 12 shown, the second housing 120 includes: a second main board body 121 disposed at the first through hole and in contact with the first main board body 111. The second main board body 121 is located on the side of the top plate 112 near the vehicle body and is spaced apart from the top plate 112. A second through hole is provided on the second main board body 121; a plurality of bottom plates 122 are connected in sequence.

[0055] In this way, an avoidance hole for avoiding the second housing 120 is provided on the vehicle body, which can make the lidar 2 partially sink into the vehicle body, enable interaction with the temperature inside the vehicle body, and improve the heat dissipation effect of the lidar 2.

[0056] AsFigure 1 and Figure 8 As shown in Figure 8 , a drain hole 16 is provided on the housing 1. The drain hole 16 is located on the side of the opening 12 close to the vehicle body and communicates with the installation cavity 11.

[0057] Since the installation cavity 11 is not a sealed cavity, water will enter during rainy days. Therefore, the upper surface of the second housing 120 that forms the installation cavity 11 is set to a shape that gradually decreases in height along the direction towards the front of the vehicle body, which can cause moisture to accumulate on the front side of the installation cavity 11 and finally flow out to the outside through the drain hole 16. The remaining moisture will not enter the interior of the vehicle body but will be evaporated by the heat dissipated during the operation of the lidar 2.

[0058] Preferably, the number of drain holes 16 is multiple, and the multiple drain holes 16 are arranged at intervals on the first side plate 113 of the housing 1.

[0059] The utility model provides a vehicle body assembly, including a vehicle body and the above-mentioned radar assembly installed on the vehicle body.

[0060] The utility model also provides a vehicle, including the above-mentioned vehicle body assembly.

[0061] The installation process of the radar assembly of the utility model is as follows:

[0062] (1) First, fix the lidar 2 to the first housing 110 with multiple fasteners (such as M6 screws);

[0063] (2) Then, pass the end of the connection line connected to the lidar 2 through the wire passing rubber sleeve 3;

[0064] (3) Apply sealant in the annular fitting groove 114 of the first housing 110, and then insert the annular fitting protrusion 124 of the second housing 120 into the annular fitting groove 114;

[0065] (4) Open an avoidance hole on the top of the vehicle body, apply sealant in the glue application groove 14 of the first housing 110, and then press it tightly on the roof of the vehicle. Wait for the glue to cure, and the connection between the radar assembly and the vehicle body is completed.

[0066] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:
