[0034] To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals represent the same or similar components or components with the same or similar functions from beginning to end. The described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0035] The embodiments of the present application provide a vehicle, which includes a vehicle body and a radar assembly 200, and the radar assembly 200 is installed on the vehicle body. Specifically, the radar assembly 200 includes a radar 210 and a radar housing 100. The radar housing 100 has an installation cavity 130, the radar 210 is arranged in the installation cavity 130, and the radar housing 100 is installed on the vehicle body.

[0036] Exemplarily, the vehicle can be an intelligent autonomous vehicle, or the vehicle can also be an ordinary human-driven vehicle. The vehicle can be a car, a truck, a trailer or a flatbed truck, etc. This is not limited in this embodiment.

[0037] In this embodiment, the installation position of the radar housing 100 is not limited and can be specifically set according to actual needs. Exemplarily, the radar housing 100 can be set at the front of the vehicle body; or, the radar housing 100 can be set at the rear of the vehicle body, and this embodiment does not limit this. In addition, the connection method between the radar housing 100 and the vehicle body is not limited. Exemplarily, the radar housing 100 and the vehicle body can be connected by screws; or, the radar housing 100 and the vehicle body can be connected by positioning pins and auxiliary pins. This embodiment does not limit this.

[0038] In this embodiment, the type of the radar 210 is not limited. Exemplarily, for autonomous vehicles, classified by the working principle of the radar, the commonly used radars currently mainly include lidar, millimeter-wave radar, and ultrasonic radar. According to the characteristics of each radar, in actual applications, a combination of multiple radars with complementary functions is often used for environmental perception.

[0039] In this embodiment, lidar is mainly used as an example of the above-mentioned radar for illustration.

[0040] Lidar is a radar system that detects the position, speed, and other characteristic quantities of a target by emitting laser beams. Its working principle is to emit a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal. After appropriate processing, relevant information about the target can be obtained, such as parameters of the target distance, azimuth, altitude, speed, attitude, and even shape, so as to detect, track, and identify targets such as airplanes and missiles. Lidar consists of a laser transmitter, an optical receiver, a turntable, and an information processing system, etc. The laser converts the electrical pulse into an optical pulse and emits it, and the optical receiver then restores the optical pulse reflected from the target into an electrical pulse and sends it to the display.

[0041] In addition, the number of radars is not further limited and can be specifically set according to the actual situation.

[0042] The structure of the radar housing provided by the embodiment of the present application will be described in detail below.

[0043] Refer to Figure 1 As shown, this embodiment provides a radar housing 100, which includes a bottom shell 110 and an upper cover 120. The upper cover 120 covers the bottom shell 110 and encloses an installation cavity 130 with the bottom shell 110, and the radar 210 is arranged in the installation cavity 130. In this way, the installation cavity 130 has a certain protection and sealing performance, which can protect the radar 210, prevent the radar 210 from being damaged, and thus help to extend the service life of the radar 210.

[0044] In this embodiment, there is no limitation on the material of the installation housing. Exemplarily, the material of the installation housing can be a metal material, such as aluminum alloy or steel material. Among them, aluminum alloy is suitable for the manufacture of the housing due to its high strength and corrosion resistance, while steel material is commonly used in the manufacture of support structures. Metal materials help to provide good electromagnetic shielding and mechanical strength. Exemplarily, the material of the installation housing can be plastic. Plastic is widely used in radar manufacturing due to its light weight, easy processing, and good electromagnetic properties.

[0045] In this embodiment, there is no limitation on the connection method between the bottom case 110 and the upper cover 120. Exemplarily, as shown in Figure 5 shown, the bottom case 110 and the upper cover 120 can be respectively provided with mounting ears 112, and connection holes are formed on the mounting ears 112. When the bottom case 110 and the upper cover 120 are assembled, the connecting member 101, such as a screw, sequentially passes through and connects the bottom case 110 and the upper cover 120. Exemplarily, one of the bottom case 110 and the upper cover 120 can be provided with a limiting post, and the other of the bottom case 110 and the upper cover 120 can be provided with a limiting hole, and the limiting post is correspondingly inserted into the limiting hole to connect the bottom case 110 and the upper cover 120. Exemplarily, the bottom case 110 and the upper cover 120 can also be connected by adhesive. This embodiment does not make a limitation on this.

[0046] Among them, in order to further improve the protection performance of the radar 210, in this embodiment, as shown in Figures 1 to 3 shown, a protection component 140 can be provided in the installation cavity 130. The bottom case 110 has a shell side wall 111, and at least part of the protection component 140 is disposed around between the side wall of the radar 210 and the shell side wall 111 of the bottom case 110.

[0047] The reason for such a setting is that when the bottom case 110 and the upper cover 120 are assembled, water stains, impurities, etc. are likely to penetrate into the connection part 131 between the bottom case and the upper cover. Therefore, disposing the protection component 140 around between the radar 210 and the shell side wall 111 of the bottom case 110 can effectively seal the connection part 131 between the bottom case and the upper cover, thereby effectively improving the protection effect on the radar 210.

[0048] In this embodiment, there is no limitation on the structure of the protection component 140. Exemplarily, the protection component 140 can be a sealing ring; or, the protection component 140 can be a waterproof rubber strip; or, the protection component 140 can be a waterproof coating. This embodiment does not make a limitation on this.

[0049] Exemplarily, when the protection component 140 is a sealing ring, the protection component 140 can be a rubber sealing ring. Among them, common rubber materials include nitrile rubber, fluororubber, silicone rubber, etc. This embodiment does not make a limitation on this.

[0050] In this embodiment, the installation position of the protection component 140 is not limited. Exemplarily, the protection component 140 can be installed on the bottom shell 110. For example, the protection component 140 can be connected to the bottom shell 110 by bonding; or, the protection component 140 can be installed on the upper cover 120. For example, the protection component 140 can be connected to the upper cover 120 by bonding. This embodiment does not limit this, and it can be specifically set according to actual needs.

[0051] In this embodiment, the shape of the protection component 140 is not limited. Exemplarily, the shape of the protection component 140 can be an annular structure, wherein the shape of the protection component 140 can be adapted to the shape of the radar 210. In this way, the protection effect on the radar 210 can be maximally improved.

[0052] Therefore, for the radar housing 100 provided in this embodiment, by providing the protection component 140, the protection and sealing effect on the radar 210 can be further improved, the radar 210 can be protected from damage, the risk of collision damage to the radar 210 can be reduced, so as to ensure the stable output of the radar 210 and contribute to extending the service life of the radar 210.

[0053] Among them, in this embodiment, the setting position of the protection component 140 is not further limited. For example, it can be set with reference to the following method:

[0054] In a possible implementation manner, as shown in Figure 2 , the protection component 140 can include a first protection piece 141, and the first protection piece 141 is an annular piece. The first protection piece 141 is disposed around between the side wall of the radar 210 and the shell side wall 111 of the bottom shell 110.

[0055] The orthographic projection of the first protection piece 141 on the shell bottom wall of the bottom shell 110 surrounds the outside of the orthographic projection of the radar 210 on the shell bottom wall of the bottom shell 110. In this way, the projection of the first protection piece 141 in the vertical direction is completely located outside the radar 210, which is beneficial to ensuring the protection of the radar 210 outside the radar 210 and improving the protection effect.

[0056] In this embodiment, the shape of the first protection piece 141 is not limited. Exemplarily, the first protection piece 141 can be a complete annular structure; or, the first protection piece 141 can be composed of two half rings. For example, the two half rings are connected by a riveting process. This embodiment does not further limit this.

[0057] In this embodiment, neither the size nor the installation position of the first protective member 141 is limited, and it can be specifically set according to actual needs. Additionally, the connection method of the first protective member 141 is not limited either. Exemplarily, the first protective member 141 can be adhered to the bottom case 110, or the first protective member 141 can be adhered to the upper cover 120. This embodiment does not limit this.

[0058] In a possible implementation, the end face of the first protective member 141 on the side close to the upper cover 120 can protrude from the end face of the radar 210 on the side close to the upper cover 120. It should be noted that in this embodiment, the protruding height of the first protective member 141 is not limited either, and it can be specifically set according to the actual situation.

[0059] Among them, in this embodiment, the end face of the first protective member 141 on the side close to the upper cover 120 can abut against the upper cover 120. In this way, the sealing performance between the bottom case 110 and the upper cover 120 can be guaranteed to the greatest extent, thereby maximizing the sealing protection effect on the radar 210.

[0060] Among them, in this embodiment, the end face of the first protective member 141 on the side close to the upper cover 120 can also be flush with the end face of the radar 210 on the side close to the upper cover 120. In this way, it is beneficial for processing, and it can also play a role in protecting the radar 210 and ensure the sealing protection effect of the radar 210.

[0061] It should be noted that the assembly method of the first protective member 141 includes but is not limited to the above methods, and this embodiment of the present application does not limit this. It should be noted that the first protective member 141 in this embodiment is a ring structure, and the shape of the first protective member 141 is adapted to the shape of the radar 210. In this way, the protection effect on the radar 210 can be maximized. Among them, in this embodiment, the dimensions such as the ring width of the first protective member 141 are not limited, and it can be specifically set according to actual needs.

[0062] In a possible implementation, there may be a gap between the end face of the radar 210 on the side close to the upper cover 120 and the upper cover 120. When there is a gap between the radar 210 and the upper cover 120, in this embodiment of the present application, referring to Figure 3 as shown, the protection assembly 140 may further include a second protective member 142, and the second protective member 142 may be a ring-shaped member.

[0063] Among them, the second protective member 142 is disposed around the end surface of the radar 210 close to the upper cover 120 and the upper cover 120. The orthographic projection of the second protective member 142 on the upper cover 120 surrounds the outside of the orthographic projection of the radar 210 on the upper cover 120. In this way, it is beneficial to further protect the radar 210 and seal the connection 131 between the bottom case and the upper cover to the greatest extent, thereby effectively improving the protection effect on the radar 210.

[0064] It should be noted that the orthographic projection of the second protective member 142 on the upper cover 120 surrounds the outside of the orthographic projection of the radar 210 on the upper cover 120. In this way, it will not affect the normal operation of the radar 210, and at the same time, it can improve the protection effect on the radar 210.

[0065] In this embodiment, the second protective member 142 and the first protective member 141 are connected. The second protective member 142 can be assembled on the upper cover 120, the first protective member 141 can be assembled on the bottom case 110 or the radar 210, and the second protective member 142 and the first protective member 141 are butt-connected. In this way, it is beneficial to reduce the docking difficulty between the upper cover 120 and the bottom case 110 during assembly and improve the assembly stability between the upper cover 120 and the bottom case 110.

[0066] Among them, the ring width of the second protective member 142 and the ring width of the first protective member 141 can be the same. In this way, it is beneficial to reduce the docking difficulty between the second protective member 142 and the first protective member 141 during assembly and improve the assembly stability of the first protective member 141 and the second protective member 142; or, the ring width of the second protective member 142 can be greater than the ring width of the first protective member 141; or, the ring width of the second protective member 142 can be less than the ring width of the first protective member 141. This embodiment does not make any limitations in this regard.

[0067] Exemplarily, the second protective member 142 can be disposed on the upper cover 120. Specifically, the second protective member 142 can be bonded to the upper cover 120; or, the second protective member 142 can be disposed on the radar 210. Specifically, the second protective member 142 can be bonded to the radar 210. This embodiment does not make any limitations in this regard.

[0068] Exemplarily, the second protective member 142 can be a sealing ring. This embodiment does not make any limitations in this regard.

[0069] In a possible implementation manner, as shown in reference to Figure 4 shown, a sealing member 102 can also be included; the sealing member 102 is disposed at the connection 131 between the bottom case and the upper cover. In this way, it helps to further improve the sealing performance of the connection 131 between the bottom case and the upper cover. Exemplarily, the sealing member 102 can be a sealing ring; or, the sealing member 102 can be a sealant. This embodiment does not make any limitations in this regard.

[0070] In this embodiment, with reference to Figure 5 as shown, the radar housing 100 may further include a waterproof and breathable component 150. There is no limitation on the installation position of the waterproof and breathable component 150. Exemplarily, the waterproof and breathable component 150 may be attached to the end face of the upper cover 120 close to the bottom shell; alternatively, the waterproof and breathable component 150 may be attached to the end face of the bottom shell close to the upper cover 120. This embodiment does not make a limitation on this.

[0071] Exemplarily, the waterproof and breathable component 150 may be a waterproof and breathable membrane. In this way, on the one hand, it helps to improve the dust and waterproof performance of the radar 210 and is beneficial to ensuring the ventilation and heat dissipation of the radar 210, preventing water from entering the radar housing 100 and damaging the circuit board or electronic components, etc.; on the other hand, it can dynamically balance the internal and external air pressures and perform the internal and external gas exchange well; on the further hand, it can protect the radar 210 from the influence of the weather. The waterproof and breathable membrane enables the radar 210 to withstand the immersion of water and other liquids for a certain period of time, keeping the radar 210 clean, thereby ensuring the working performance and service life of the radar 210; on the still further hand, the processed product of the waterproof and breathable membrane is thin and light, with good concealment, bringing convenience to the design and production of the product.

[0072] In a possible implementation manner, with reference to Figure 5 as shown, a baseband board 160, a shielding board 170, and an antenna board 180 are accommodated in the installation cavity 130; the shielding board 170 is connected between the baseband board 160 and the antenna board 180, and the antenna board 180 is located on the side of the shielding board 170 close to the upper cover 120.

[0073] The antenna board 180 is used for signal transmission and reception. For example, in a mobile communication system, the antenna board 180 is widely used for outdoor signal coverage; in addition, the antenna board 180 can also be used for signal transmission and reception between a base station and a terminal device. This embodiment does not make a limitation on this.

[0075] The shielding board is used to shield the electromagnetic interference between the baseband board 160 and the antenna board 180. In this way, it can prevent electromagnetic waves from being transmitted from the baseband board 160 to the antenna board 180, or from the antenna board 180 to the baseband board 160, thereby reducing or eliminating the electromagnetic interference between them.

[0076] In this embodiment, a heat sink may be connected between the baseband board 160 and the shielding board 170. In this way, it helps to improve the heat dissipation effect between the baseband board 160 and the shielding board 170, ensuring the normal operation of the baseband board 160 and the shielding board 170; or, a heat sink may be connected between the shielding board 170 and the antenna board 180, which helps to improve the heat dissipation effect between the shielding board 170 and the antenna board 180, ensuring the normal operation of the baseband board 160 and the shielding board 170. Thus, it can ensure to the greatest extent that the electronic components can work in a stable temperature environment, thereby improving the reliability and stability of the system.

Specifically, referring to Figure 4 as shown, the installation board 190 may be provided with an installation groove 191, and the baseband board 160 is located in the installation groove 191. In this way, it helps to avoid the problem that the baseband board 160 is easily damaged due to contact between the baseband board 160 and the bottom case 110, and helps to improve the assembly stability and connection strength between the baseband board 160 and the bottom case 110.

[0078] Exemplarily, the shapes of the installation board 190 and the baseband board 160 may be adapted to each other, which helps to reduce the docking difficulty between the installation board 190 and the baseband board 160 during the assembly process.
