[0015] Beneficial effects of this application

[0016] The automotive roof-mounted sensor bracket of this application provides a centralized platform for the installation of multiple devices, avoiding the space waste caused by the scattered installation of multiple devices in other parts of the vehicle. This makes the layout of multiple devices more compact and reasonable, improving the utilization rate of roof space. Compared with existing installation methods, by opening multiple wiring harness holes on the roof bracket, the wiring harnesses of each device are isolated from the external environment, preventing the wiring harnesses of each device from being directly exposed to the roof and subject to corrosion from external factors. This reduces the risk of aging and damage to the wiring harnesses and extends the service life of each device. At the same time, the wiring harness holes on the roof-mounted sensor bracket provide a fixed routing channel for the wiring harnesses of each device, allowing the wiring harnesses of each device to be neatly arranged according to the designed path, avoiding the situation where the wiring harnesses of each device are tangled. When a device in the roof-mounted sensor bracket malfunctions, maintenance personnel can quickly locate the faulty device wiring harness through the wiring harness holes, without having to search through a messy exposed wiring harness, greatly improving the efficiency of fault diagnosis and reducing the difficulty of maintenance.

In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] This application proposes a sensor bracket for automotive rooftops, such as... Figures 1 to 7 As shown, it includes: a fixing plate 100, a first cover plate 300, and a second cover plate 500; the fixing plate 100 is suitable for installation on a roof rack; the top surface of the fixing plate 100 has a first mounting groove 110 and two second mounting grooves 120, the two second mounting grooves 120 are symmetrically arranged, the first mounting groove 110 is located between the two second mounting grooves 120, the first cover plate 300 is disposed in the first mounting groove 110, and the second cover plate 500 is fastened to the top of the first cover plate 300; the fixing plate 100 has a receiving chamber 150 on the side opposite to the first cover plate 300, the first mounting groove 110 of the fixing plate 100 has a first wire harness hole 111, the first wire harness hole 111 communicates with the receiving chamber 150, suitable for allowing the wire harness of the solid-state lidar to extend into the receiving chamber 150 through the first wire harness hole 111; each of the two second mounting grooves 120 has a first mounting groove 110. Two wire harness holes 121 are connected to the receiving chamber 150, allowing the wire harness of the signal receiver to extend into the receiving chamber 150 through the second wire harness holes 121; the first cover plate 300 has a cavity with one end open, the opening of the first cover plate 300 facing the first mounting groove 110, and a third wire harness hole 310 is provided on the top of the first cover plate 300, allowing the wire harness of the camera device to pass through the third wire harness hole 310 and the first wire harness hole 111 in sequence into the receiving chamber 150; the second cover plate 500 has a cavity with one end open, the opening of the second cover plate 500 facing the first cover plate 300; the top of the second cover plate 500 has a third mounting groove 510, suitable for mounting a mechanical lidar, and a fourth wire harness hole 511 is provided in the third mounting groove 510, which is connected to the cavity of the second cover plate 500.

[0032] It should be noted here that, as Figures 1 to 3As shown, the fixing plate 100 provides a stable mounting base for the entire device. The fixing plate 100 has a receiving chamber 150 on the side opposite to the first cover plate 300, providing a centralized storage space for the wiring harnesses of the devices within the automotive roof sensor bracket. This allows the wiring harnesses of each device to be hidden inside the automotive roof sensor bracket, avoiding aging and damage caused by natural factors such as wind, sun, and rain, thus extending the service life of each device. The first mounting slot 110 is suitable for providing an installation position for the solid-state LiDAR, ensuring the solid-state LiDAR is securely mounted. Mounted on the fixed plate 100, the first mounting slot 110 can also fix the solid-state lidar to a certain extent, restricting its movement during vehicle operation and improving the stability and reliability of the solid-state lidar during use. The first mounting slot 110 has a first wire harness hole 111, which allows the solid-state lidar wire harness to extend into the receiving chamber 150 through the first wire harness hole 111. This achieves the orderly arrangement and concealment of the solid-state lidar wire harness, avoids the safety hazards caused by the exposed solid-state lidar wire harness, and facilitates centralized management and maintenance of the solid-state lidar wire harness.

[0033] like Figures 1 to 4 As shown, when the first cover plate 300 is fixedly mounted on the first mounting groove 110, the solid-state LiDAR is located inside the cavity of the first cover plate 300. The design of the first cover plate 300 avoids direct exposure of the solid-state LiDAR to the external environment, extending its service life. Simultaneously, the top of the first cover plate 300 is suitable for providing a stable mounting platform for the camera device, ensuring its stability during use. A third wire harness hole 310 is provided on the top of the first cover plate 300. The third wire harness hole 310 communicates with the cavity of the first cover plate 300, and is correspondingly arranged with the first wire harness hole 111. Hole 310 provides a clear wiring channel for the camera device's wiring harness, allowing the harness to pass sequentially through the third wiring harness hole 310, the cavity of the first cover plate 300, and the first wiring harness hole 111 into the receiving chamber 150. This prevents the camera device's wiring harness from becoming tangled with the wiring harnesses of other devices, ensuring that the camera device's wiring harness is laid out in an orderly manner. This wiring method hides the camera device's wiring harness inside the first cover plate 300 and the receiving chamber 150, preventing the camera device's wiring harness from being exposed to the external environment, extending the lifespan of the camera device, and reducing equipment failures caused by wiring harness damage.

[0034] like Figure 1 , Figure 6As shown, when the second cover plate 100 is fastened to the top of the first cover plate 300, the camera device is located inside the cavity of the second cover plate 500. The design of the second cover plate 500 avoids direct exposure of the camera device to the external environment, extending the service life of the camera device. The third mounting slot 510 is suitable for providing an installation position for the mechanical lidar, ensuring that the mechanical lidar is stably installed on the top of the second cover plate 500. At the same time, the third mounting slot 510 can also play a certain role in fixing the mechanical lidar, limiting its movement during vehicle operation, and improving the stability and reliability of the mechanical lidar during use. A fourth wire harness hole 511 is opened in the third mounting slot 510, and the fourth wire harness hole 511 is connected to the first cover plate 300. The three wire harness holes 310 are correspondingly arranged, and the fourth wire harness hole 511 is connected to the cavity of the second cover plate 500 and the subsequent third wire harness hole 310 and first wire harness hole 111, providing a fixed wire harness channel for the mechanical lidar's wire harness. This allows the mechanical lidar's wire harness to be laid out in an orderly manner according to the designed path, avoiding the messy distribution of the mechanical lidar's wire harness and improving the standardization and neatness of the mechanical lidar's wire harness arrangement. At the same time, this wiring method hides the mechanical lidar's wire harness inside the roof bracket, preventing the mechanical lidar's wire harness from being exposed to the external environment, extending the mechanical lidar's service life, and reducing equipment failures caused by mechanical lidar damage.

[0035] like Figures 1 to 3 As shown, the second mounting slot 120 is suitable for providing an installation position for the signal receiver. The two second mounting slots 120 are symmetrically arranged on the fixing plate 100 to form a balanced layout structure, which helps to evenly distribute the weight of the roof equipment and avoid the fixing plate 100 from tilting due to uneven force caused by the concentrated installation of the equipment on one side. The second mounting slot 120 is provided with a second wire harness hole 121, so that the wire harness of the signal receiver can extend into the receiving chamber 150 through the second wire harness hole 121, realizing the orderly arrangement and concealment of the signal receiver wire harness and avoiding the safety hazards caused by the exposed signal receiver wire harness.

[0036] The automotive roof-mounted sensor bracket of this application provides a centralized platform for the installation of multiple devices, avoiding the space waste caused by the scattered installation of multiple devices in other parts of the vehicle. This allows for a more compact and rational layout of the devices, improving the utilization of roof space. Compared with existing installation methods, by opening multiple wiring harness holes on the roof bracket, the wiring harnesses of each device are isolated from the external environment, preventing them from being directly exposed to the roof and subject to external corrosion. This reduces the risk of aging and damage to the wiring harnesses and extends the service life of each device. Simultaneously, the wiring harness holes on the roof-mounted sensor bracket provide a fixed routing channel for the wiring harnesses of each device, allowing them to be neatly arranged according to the designed path, preventing them from becoming tangled. When a device within the roof-mounted sensor bracket malfunctions, maintenance personnel can quickly locate the faulty wiring harness through the wiring harness holes, eliminating the need to search through a messy array of exposed wiring, greatly improving troubleshooting efficiency and reducing maintenance difficulty.

[0037] In one possible implementation, such as Figures 1 to 6 As shown, a first detection hole 320 is provided on one side of the first cover plate 300; a second detection hole 520 is provided on the second cover plate 500, and the first detection hole 320 and the second detection hole 520 are located on the same side.

[0038] It should be noted that the first detection aperture 320 is matched with the detection end of the solid-state lidar. The first detection aperture 320 is designed to provide a specific opening for the detection end of the solid-state lidar, allowing it to emit and receive laser beams without obstruction, thereby ensuring accurate detection of the vehicle's surrounding environment. The second detection aperture 520 is matched with the acquisition end of the camera device. The second detection aperture 520 is designed to provide the camera device with a clear and unobstructed field of view, enabling it to accurately capture image information about the vehicle's surroundings. The design of the first detection aperture 320 and the second detection aperture 520 being located on the same side ensures that the solid-state lidar and the camera device have similar perspectives and directions when acquiring data, facilitating their collaborative work and thus providing a more accurate understanding of the vehicle's surroundings.

[0039] In one possible implementation, such as Figure 1 , Figure 4 , Figure 5 As shown, a fixing part 400 is provided in the cavity of the first cover plate 300; a first mounting hole 330 is provided on the outer side wall of the first cover plate 300, and a guide hole 410 is provided on the fixing part 400, and the first mounting hole 330 and the guide hole 410 are connected. The first bolt passes through the side wall of the first cover plate 300, the fixing part 400 and the fixing plate 100 in sequence.

[0040] It should be noted here that, as Figure 5 As shown, the main body of the fixing part 400 has a columnar structure. The fixing part 400 is fixedly connected to the first cover plate 300. The fixing part 400 has a guide hole 410, which is a through hole and communicates with the first mounting hole 330. The guide hole 410 provides accurate guidance for the installation of the first bolt, making it more convenient and faster for installers to install the first bolt, thus improving installation efficiency. Correspondingly, as... Figure 1 , Figure 2 As shown, a first fixing hole 130 is provided on the fixing plate 100. A first bolt passes through the first mounting hole 330 and the guide hole 410 of the fixing part 400 in sequence and connects with the first fixing hole 130 of the fixing plate 100. By setting the fixing part 400 in the cavity of the first cover plate 300 and fixing it with the first bolt, the stability of the connection between the first cover plate 300 and the fixing plate 100 is enhanced, so that the first cover plate 300 can be more stably installed on the fixing plate 100 during vehicle operation.

[0041] In one possible implementation, such as Figure 5 As shown, there are two or more fixing parts 400; the two or more fixing parts 400 are arranged symmetrically in pairs. It should be noted that the two or more fixing parts 400 can evenly distribute the external force on the first cover plate 300 to the fixing parts 400 and the fixing plate 100, avoiding stress concentration in a certain area, thereby improving the load-bearing capacity of the overall structure.

[0042] In one possible implementation, such as Figure 1 , Figure 4 , Figure 6 As shown, a third mounting hole 530 is provided on the side wall of the second cover plate 500, and a third fixing hole 340 is provided on the top of the first cover plate 300. The third screw passes through the third mounting hole 530 and connects with the third fixing hole 340, thereby realizing the second cover plate 500 being stably installed on the top of the first cover plate 300.

[0043] In one possible implementation, the bottom of the fixing plate 100 has two fixing grooves 160; the two fixing grooves 160 are arranged opposite each other and located on both sides of the length of the receiving chamber 150.

[0044] It should be noted here that, as Figures 1 to 3As shown, the cross-section of the fixing groove 160 is U-shaped. The length of the fixing groove 160 extends along the width of the fixing plate 100, and the fixing groove 160 matches the roof rack. The fixing plate 100 is snapped onto the roof rack through two fixing grooves 160. The design of the two fixing grooves 160 opposite each other forms a stable support structure, which can effectively distribute the weight of the roof rack evenly on the roof rack, and avoid the roof rack from shaking or tilting due to unstable center of gravity.

[0045] In one possible implementation, such as Figure 3 , Figure 7 As shown, it also includes a reinforcement member 200; a reinforcement groove is provided in the fixing groove 160, the reinforcement member 200 is located in the reinforcement groove, the main body of the reinforcement member 200 is U-shaped, and the opening faces the side away from the receiving chamber 150, and the second bolt passes through the fixing plate 100 and is connected to the reinforcement member 200.

[0046] It should be noted that a reinforcing groove is provided near the receiving chamber 150 in the fixing groove 160. The reinforcing groove matches the outer contour of the reinforcing member 200 and is suitable for providing a receiving space for the reinforcing member 200. The opening of the reinforcing member 200 matches the roof rack, and the roof rack is located in the opening of the reinforcing member 200. A second fixing hole 210 is provided on the reinforcing member 200. The axis of the second fixing hole 210 is perpendicular to the length direction of the reinforcing member 200. Correspondingly, a second mounting hole 140 is provided on the side wall of the fixing plate 100. The second bolt passes through the second mounting hole 140 on the fixing plate 100 and connects with the second fixing hole 210 on the reinforcing member 200. By setting the reinforcing member 200, the connection between the fixing plate 100 and the roof rack is more stable, effectively preventing the roof rack and the roof rack from loosening or shifting due to vibration, bumps and other factors during vehicle operation, thereby ensuring the stability of the entire roof rack system.

[0047] Furthermore, such as Figure 7 As shown, there are two or more second fixing holes 210, and the two or more second fixing holes 210 are equidistantly arranged along the length direction of the reinforcement 200.

[0048] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
