Description
Technical Field
[0001] This application relates to the field of vehicle sensor technology, and more particularly to a sensor assembly and a vehicle. Background Technology
[0002] With the development of technology, vehicle driver assistance technology has become increasingly mature, greatly improving driving safety and convenience. To achieve driver assistance functions, multiple onboard sensors need to be installed in the vehicle. Among them, the lidar module is an important sensor for realizing driver assistance functions, used to detect objects in the vehicle's surrounding environment.
[0003] LiDAR modules are typically mounted on the exterior of a vehicle (e.g., above the front crossbeam of the roof). However, this mounting method is not conducive to the protection of the LiDAR module and increases wind resistance during vehicle movement. To address this issue, a proposed solution involves mounting the LiDAR module inside the vehicle's windshield. The LiDAR module is fixed to the windshield via a bracket, thereby utilizing the windshield to protect the LiDAR module and reduce wind resistance during vehicle movement.
[0004] However, after the lidar module is installed inside the vehicle, its heat dissipation capacity is reduced. After prolonged use, the lidar module may overheat, affecting its normal operation and even causing damage. Utility Model Content
[0005] In view of this, the present application provides a sensor assembly and a vehicle. The present application is beneficial to improving the heat dissipation capacity of the lidar module installed inside the vehicle, ensuring the normal use of the lidar module, and reducing the risk of lidar module overheating and damage.
[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0007] This application provides a sensor assembly, including:
[0008] Windshield;
[0009] A first bracket is located on the side of the windshield facing the inside of the vehicle, and a first side of the first bracket is connected to the windshield.

[0013] In this embodiment, the LiDAR module is connected to the windshield via a first bracket and to the first bracket via a second bracket. The LiDAR module is mounted on the second bracket, thus placing it inside the windshield. This extends the module's lifespan and reduces wind resistance during vehicle operation. By providing heat dissipation holes on the second bracket, which correspond to the heat dissipation components on the LiDAR module, the heat dissipation capacity of the LiDAR module inside the vehicle is improved, ensuring normal operation and reducing the risk of overheating and damage. The heat dissipation holes on the second bracket also reduce its weight, contributing to vehicle weight reduction.
[0014] In one possible implementation of this application, the second bracket includes a mounting base, the lidar module is connected to the mounting base, and the heat dissipation holes are disposed on the mounting base.
[0015] This application embodiment improves the heat dissipation capacity of the lidar module inside the vehicle by setting the lidar module on the mounting base plate and opening heat dissipation holes on the mounting base plate, thereby ensuring the normal use of the lidar module and reducing the risk of overheating and damage to the lidar module.

[0018] The first fastener in this embodiment can be a bolt, screw, etc. After passing through the mounting base plate, the first fastener connects to the lidar module, thereby achieving a detachable connection between the lidar module and the second bracket, facilitating the installation and subsequent maintenance of the lidar module. By setting a first positioning post and a first positioning hole on the lidar module, the connection and positioning between the lidar module and the second bracket can be achieved through the connection and cooperation between the first positioning post and the first positioning hole, which helps to improve the assembly efficiency of the lidar module and the second bracket.

The ceiling decorative component is provided with ventilation holes, which correspond to the heat dissipation holes.

The ceiling trim piece has ventilation holes corresponding to the heat dissipation holes, ensuring that the heat dissipation of the LiDAR module is not affected. This guarantees the heat dissipation capacity of the LiDAR module within the vehicle, ensuring its normal operation and reducing the risk of overheating and damage.
[0021] In one possible implementation of this application, the second bracket further includes at least two sidewalls connected to the mounting base plate, and the two sidewalls are disposed opposite to each other; the second bracket further includes a flange disposed at one end of the sidewall away from the mounting base plate, and / or the flange disposed on one side of the mounting base plate, and the flange is connected to the first bracket.
[0022] The second bracket in this embodiment is connected to the first bracket via a flange, and the first bracket is connected to the windshield, thereby fixing the LiDAR module to the windshield of the vehicle, which helps to extend the service life of the LiDAR module and reduce wind resistance during vehicle operation.
[0023] In one possible implementation of this application, the flange is provided with at least one second mounting hole; the second side of the first bracket is provided with at least two fixing posts, each fixing post having a second fixing hole; the second fastener passes through the second mounting hole and connects to the second fixing hole.
[0024] The flange is also provided with at least one second positioning hole, and the second side of the first bracket is provided with at least one second positioning post, which passes through the second positioning hole.
[0025] The second fastener in this embodiment can be a bolt, screw, etc. After passing through the flange, the second fastener connects to the fixing post of the first bracket, thereby realizing a detachable connection between the first bracket and the second bracket, which facilitates the installation and subsequent maintenance and disassembly of the second bracket. By providing a second positioning hole on the second bracket and a second positioning post on the second side of the first bracket, the connection and positioning between the first bracket and the second bracket can be achieved through the connection and cooperation between the second positioning post and the second positioning hole, which helps to improve the assembly efficiency of the first bracket and the second bracket.
[0026] In one possible implementation of this application, a front-view camera is also included; the mounting base plate is further provided with a front-view camera mounting plate, and the front-view camera is detachably mounted on the front-view camera mounting plate.
[0027] This embodiment of the application mounts a forward-view camera onto a forward-view camera mounting plate on a second bracket, thereby providing the vehicle with accurate close-range environmental information through the forward-view camera, supporting precise operation.
[0028] In one possible implementation of this application, the first bracket has a fixing part and a mounting part on its first side. The fixing part is connected to the windshield, and the mounting part has a gap with the windshield. The mounting part has a first through hole and a second through hole. The lidar module passes through the first through hole, and the forward-looking camera passes through the second through hole.
[0029] In this embodiment of the application, the lidar module and the forward-looking camera are respectively installed in the first through hole and the second through hole on the mounting part, and a gap is formed between the mounting part and the windshield, so as to avoid interference between the lidar module and the forward-looking camera and the windshield.
[0030] In one possible implementation of this application, an interior rearview mirror and an interior rearview mirror adapter are also included. The interior rearview mirror and the interior rearview mirror adapter are located on the side of the headliner facing away from the first bracket. The interior rearview mirror is connected to the interior rearview mirror adapter, and the interior rearview mirror adapter is connected to the first bracket.

[0032] This application also provides a vehicle including any of the sensor components described above.
[0033] Because the vehicle in this embodiment uses the aforementioned sensor components, the LiDAR module can be placed inside the windshield, which helps extend the lifespan of the LiDAR module and reduce wind resistance during vehicle operation. By providing heat dissipation holes on the second bracket and aligning these holes with the heat dissipation components on the LiDAR module, the heat dissipation capacity of the LiDAR module inside the vehicle is improved, ensuring normal operation of the LiDAR module and reducing the risk of overheating and damage.

[0056] As described in the background section, when a LiDAR module is typically placed on the exterior of a vehicle, it can fully contact the outside air during vehicle operation, thus dissipating heat effectively. However, when the LiDAR module is placed inside the vehicle, its heat dissipation capacity is reduced, which may lead to overheating after prolonged use. This can affect the normal operation of the LiDAR module and, in severe cases, even cause damage to it.
[0057] In view of this, the embodiments of this application aim to provide a sensor assembly and a vehicle, which improves the heat dissipation capacity of the lidar module inside the vehicle by setting heat dissipation holes on the bracket and making the heat dissipation holes correspond to the heat dissipation components on the lidar module, thereby ensuring the normal use of the lidar module and reducing the risk of overheating and damage to the lidar module.
[0058] The embodiments of this application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0059] This application provides a sensor assembly for mounting sensors such as lidar. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles generally have wheels and a body. The body includes a windshield and a lidar module installed inside the windshield. The lidar module is used to detect objects in the vehicle's surrounding environment to achieve assisted driving functions.
[0060] Please refer to Figures 1-6 ,in Figure 1 The first-person perspective in the text is the viewpoint from the front of the vehicle looking towards the interior. Figure 2 The second perspective is the view from inside the vehicle looking at the side of the sensor assembly. This application embodiment provides a sensor assembly, including:
[0061] The windshield 100 can be fixed to the front of the cockpit by adhesive.
[0062] A first bracket 200 is located on the side of the windshield 100 facing the interior of the vehicle, and a first side of the first bracket 200 (i.e., the side facing the windshield 100) is connected to the windshield 100. For example, the first bracket 200 can be connected to the windshield 100 by means of adhesive bonding, snap-fitting, or other methods.
[0063] The second bracket 300 is located on the second side of the first bracket 200 (i.e., the side facing away from the windshield 100) and is connected to the first bracket 200. For example, the second bracket 300 can be connected and fixed to the first bracket 200 by means of snap-fit, bolt connection or other methods.
[0064] A lidar module 400 is mounted on a second bracket 300. For example, the lidar module 400 can be connected and fixed to the second bracket 300 by means of snap-fit, bolt connection, or other methods.
[0065] Please refer to Figures 3-5 The second bracket 300 in this embodiment of the application is provided with heat dissipation holes 311. The shape and size of the heat dissipation holes 311 can be set as needed. The heat dissipation holes 311 correspond to the heat dissipation components of the LiDAR module 400. It can be understood that the LiDAR module 400 can be directly covered on the heat dissipation holes 311. The heat dissipation components of the LiDAR module 400 (e.g., air-cooled or water-cooled components) can be partially or completely located within the heat dissipation holes 311. The heat generated by the LiDAR module 400 during use can be quickly dissipated to the vehicle interior through the heat dissipation holes 311, and then transferred to the outside of the vehicle through the vehicle's air conditioning system, thereby reducing the temperature of the LiDAR module 400 during use and ensuring that the LiDAR module 400 can work smoothly and normally.
[0066] As described above, in this embodiment, the first bracket 200 is connected to the windshield 100, and the second bracket 300 is connected to the first bracket 200. The lidar module 400 is mounted on the second bracket 300, thus placing the lidar module 400 inside the windshield 100. This helps extend the service life of the lidar module 400 and reduces wind resistance during vehicle operation. By providing heat dissipation holes 311 on the second bracket 300 and aligning these holes with the heat dissipation components on the lidar module 400, the heat dissipation capacity of the lidar module 400 inside the vehicle is improved, ensuring its normal operation and reducing the risk of overheating and damage. Furthermore, the heat dissipation holes 311 on the second bracket 300 also reduce its weight, contributing to vehicle weight reduction.
[0067] Please continue to refer to Figures 3-5 The second bracket 300 in this embodiment includes a mounting base plate 310, the lidar module 400 is connected to the mounting base plate 310, and heat dissipation holes 311 are provided on the mounting base plate 310.
[0068] In this embodiment, the lidar module 400 is mounted on the mounting base plate 310, and heat dissipation holes 311 are opened on the mounting base plate 310. This improves the heat dissipation capacity of the lidar module 400 inside the vehicle, ensures the normal use of the lidar module 400, and reduces the risk of overheating and damage to the lidar module 400.
[0069] Exemplarily, the mounting substrate 310 of this application embodiment is provided with a plurality of first mounting holes 312. The first mounting holes 312 can be through holes penetrating the mounting substrate 310, and the plurality of first mounting holes 312 are arranged around the heat dissipation hole 311. The lidar module 400 is provided with a plurality of first fixing holes (not shown in the figure). The first fixing holes can be threaded holes, and the plurality of first fixing holes correspond one-to-one with the plurality of first mounting holes 312. The first fastener (not shown in the figure) passes through the first mounting hole 312 and connects to the corresponding first fixing hole. Exemplarily, the projection of the mounting substrate 310 of this application embodiment is generally rectangular, and the mounting substrate 310 is provided with four first mounting holes 312, which are respectively arranged near the four corners of the mounting substrate 310. The lidar module 400 includes a housing, and four first fixing holes are provided on one side of the housing. The first fastener can be a bolt or a screw. The first fastener passes through the first mounting hole 312 and connects to the corresponding first fixing hole, thereby fixing the lidar module 400 to the mounting substrate 310.
[0070] Furthermore, the mounting substrate 310 is provided with at least one first positioning post 313, and the lidar module 400 is provided with at least one first positioning hole (not shown in the figure), with the first positioning post 313 passing through the first positioning hole. Exemplarily, the mounting substrate 310 of this embodiment may be provided with two first positioning posts 313, which are respectively positioned close to two first mounting holes 312 located diagonally opposite each other. The outer casing of the lidar module 400 is correspondingly provided with two first positioning holes, which are located diagonally opposite each other on one side of the casing.
[0071] In this embodiment, a first fastener passes through the mounting base plate 310 and connects to the lidar module 400, thereby achieving a detachable connection between the lidar module 400 and the second bracket 300, facilitating the installation and subsequent maintenance disassembly of the lidar module 400. By providing a first positioning post 313 and a first positioning hole on the lidar module 400, the connection and positioning between the lidar module 400 and the second bracket 300 can be achieved through the connection and cooperation between the first positioning post 313 and the first positioning hole, which helps to improve the assembly efficiency of the lidar module 400 and the second bracket 300.
[0072] Please continue to refer to Figure 1 and Figure 2 This application embodiment also includes a ceiling trim 500, which is detachably connected to the first bracket 200. For example, as... Figure 6As shown, in this embodiment of the application, the second side of the first bracket 200 may be provided with multiple slots 250, which are spaced apart circumferentially along the first bracket 200. The ceiling trim 500 may be provided with multiple buckles, which are then engaged and fixed to the multiple slots 250 one by one. After installation and fixing, the second bracket 300 is located between the first bracket 200 and the ceiling trim 500, and the ceiling trim 500 completely covers the first bracket 200, the second bracket 300, and the LiDAR module 400, which helps to improve the aesthetics of the vehicle interior. The ceiling trim 500 is provided with ventilation holes (not shown in the figure), which correspond to the heat dissipation holes 311.
[0073] This embodiment of the application uses a ceiling trim piece 500 to conceal the first bracket 200, the second bracket 300, and the LiDAR module 400, thereby improving the aesthetics of the vehicle interior. The ceiling trim piece 500 has ventilation holes corresponding to the heat dissipation holes 311, ensuring that the heat dissipation of the LiDAR module 400 is not affected. This guarantees the heat dissipation capacity of the LiDAR module 400 within the vehicle, ensuring its normal operation and reducing the risk of overheating and damage.
[0074] Please continue to refer to Figures 4-6 The second bracket 300 in this embodiment further includes at least two sidewalls 320, which are connected to the mounting substrate 310 and are disposed opposite to each other. The second bracket 300 also includes a flange 330, which is disposed at one end of the sidewall 320 away from the mounting substrate 310, and / or the flange 330 is disposed on one side of the mounting substrate 310, and is connected to the first bracket 200. For example, as... Figure 4 As shown, a flange 330 is provided on the left side wall 320, a flange 330 is provided on the right side wall 320, and a flange 330 is also provided on the right side of the mounting base 310.

[0075] In this embodiment, the second bracket 300 is connected to the first bracket 200 via a flange 330. The first bracket 200 is connected to the windshield 100, thereby fixing the lidar module 400 to the windshield 100 of the vehicle. This helps to extend the service life of the lidar module 400 and reduce wind resistance during vehicle operation.
[0076] Specifically, in this embodiment of the application, the flange 330 is provided with at least one second mounting hole 331, which can be a through hole. For example, as shown... Figure 4 and Figure 5As shown, each flange 330 in this embodiment of the application is provided with a second mounting hole 331. The second side of the first bracket 200 is provided with at least two fixing posts, each fixing post having a second fixing hole 210, which can be a threaded hole. For example, as... Figure 6 As shown, the second side of the first bracket 200 is provided with three fixing posts arranged in a triangle, and each fixing post has a second fixing hole 210. The second fastener 610 passes through the second mounting hole 331 and connects to the second fixing hole 210. The second fastener 610 can be a bolt or a screw.
[0077] In this embodiment, the flange 330 is further provided with at least one second positioning hole 332, and the second side of the first bracket 200 is provided with at least one second positioning post 220, which passes through the second positioning hole 332.

Figure 4 As shown in the embodiment of this application, a second positioning hole 332 is provided on the flange 330 of both sidewalls 320, that is, the second bracket 300 is provided with two second positioning holes 332. Correspondingly, as Figure 6 As shown, the first bracket 200 is also provided with two matching second positioning posts 220.
[0078] In this embodiment, the second fastener 610 passes through the flange 330 and connects to the fixing post of the first bracket 200, thereby achieving a detachable connection between the first bracket 200 and the second bracket 300, facilitating the installation and subsequent maintenance disassembly of the second bracket 300. By providing a second positioning hole 332 on the second bracket 300 and a second positioning post 220 on the second side of the first bracket 200, the connection and positioning between the first bracket 200 and the second bracket 300 can be achieved through the connection and cooperation between the second positioning post 220 and the second positioning hole 332, which helps to improve the assembly efficiency of the first bracket 200 and the second bracket 300.
[0079] Please continue to refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 This application embodiment also includes a front-view camera 700, and a front-view camera mounting plate 340 is further provided on the mounting base plate 310. Exemplarily, the front-view camera mounting plate 340 can be disposed on... Figure 4 The left-side flange 330 is shown between the mounting base plate 310. The front-view camera 700 is detachably mounted on the front-view camera mounting plate 340, which facilitates installation and subsequent maintenance removal.
[0080] In this embodiment, the forward-view camera 700 is mounted on the forward-view camera mounting plate 340 of the second bracket 300, thereby providing the vehicle with accurate close-range environmental information through the forward-view camera 700, supporting precise operation.
[0081] Specifically, such as Figure 4 and Figure 5 As shown, the front-view camera mounting plate 340 of this embodiment is provided with a front-view camera positioning hole 341, two third mounting holes 342, and two third positioning holes 343. The two third mounting holes 342 and the two third positioning holes 343 are arranged around the front-view camera positioning hole 341. The two third mounting holes 342 are arranged diagonally, and the two third positioning holes 343 are also arranged diagonally. The front-view camera 700 passes through the front-view camera positioning hole 341. Two corresponding third fixing holes and two third positioning posts can be provided on the housing of the front-view camera 700. The two third fixing holes and the two third positioning posts are also arranged diagonally. A third fastener passes through the third mounting hole 342 and connects to the corresponding third fixing hole. The third positioning post passes through the third positioning hole 343.
[0082] In this embodiment, a third fastener passes through the front-view camera mounting plate 340 and connects to the front-view camera 700, thereby achieving a detachable connection between the front-view camera 700 and the second bracket 300, facilitating the installation and subsequent maintenance of the front-view camera 700. By providing a third positioning hole 343 and a third positioning post on the front-view camera 700, the connection and positioning between the front-view camera 700 and the second bracket 300 can be achieved through the connection and cooperation between the third positioning hole 343 and the third positioning post, which helps to improve the assembly efficiency of the front-view camera 700 and the second bracket 300.
[0083] Please continue to refer to Figure 1 and Figure 6 In this embodiment, the first bracket 200 has a fixing part 230 and a mounting part 240 on its first side. The fixing part 230 is connected to the windshield 100. Exemplarily, the first bracket 200 in this embodiment can be a plastic bracket, and the fixing part 230 of the first bracket 200 can be bonded to the windshield 100 with adhesive. A gap is formed between the mounting part 240 and the windshield 100, and the specific size of this gap can be set as needed. Figure 6 As shown, the mounting portion 240 is provided with a first through hole 241 and a second through hole 242. The lidar module 400 passes through the first through hole 241, and the forward-looking camera 700 passes through the second through hole 242. It can be understood that the above-mentioned gaps allow the lidar module 400 and the forward-looking camera 700 to avoid interference with the windshield 100 and maintain a suitable distance.
[0084] In this embodiment of the application, the lidar module 400 and the forward-view camera 700 are respectively installed in the first through hole 241 and the second through hole 242 on the mounting part 240. A gap is formed between the mounting part 240 and the windshield 100, thereby avoiding interference between the lidar module 400 and the forward-view camera 700 and the windshield 100.
[0085] Please continue to refer to Figure 1 and Figure 2 This application embodiment also includes an interior rearview mirror 810 and an interior rearview mirror adapter 820, which are located on the side of the headliner 500 opposite to the first bracket 200.

[0086] For example, such as Figure 6 As shown, the first bracket 200 may be provided with multiple interior rearview mirror mounting holes 260, and the interior rearview mirror adapter 820 may be connected to the interior rearview mirror mounting holes 260 by fasteners. The interior rearview mirror 810 may be hinged to the interior rearview mirror adapter 820 by means of pins or other parts, thereby facilitating the adjustment of the angle of the interior rearview mirror 810.
[0087] The rearview mirror 810 of this application embodiment is connected to the first bracket 200 through the rearview mirror adapter 820, thereby enabling the sensor assembly to integrate the function of the rearview mirror 810, which helps to reduce the number of parts inside the vehicle.
[0088] Please continue to refer to Figure 1 In this embodiment of the application, a rain sensor 900 is also provided. The rain sensor 900 is mounted on the first bracket 200 and is attached to the windshield 100. The rain sensor 900 can sense the amount of rain on the windshield 100 and transmit the corresponding information to the vehicle controller. The vehicle controller can then control the wipers to swing at an appropriate speed.
[0089] This application also provides a vehicle including the aforementioned sensor assembly.
[0090] Because the vehicle in this embodiment uses the aforementioned sensor components, the LiDAR module can be placed inside the windshield, which helps extend the lifespan of the LiDAR module and reduce wind resistance during vehicle operation. By providing heat dissipation holes on the second bracket and aligning these holes with the heat dissipation components on the LiDAR module, the heat dissipation capacity of the LiDAR module inside the vehicle is improved, ensuring normal operation of the LiDAR module and reducing the risk of overheating and damage.
