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, lidar is an important sensor for realizing driver assistance functions, used to detect objects in the vehicle's surrounding environment.

[0003] LiDAR sensors 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 sensor and increases wind resistance during vehicle movement. To address this issue, a proposed solution involves mounting the LiDAR sensor inside the vehicle's windshield. The LiDAR sensor is fixed to the windshield via a bracket, thereby utilizing the windshield to protect the LiDAR sensor and reduce wind resistance during vehicle movement.

[0004] However, even with the aforementioned technologies, lidar may be affected by stray light from the external environment during use, which can impact its detection accuracy. Utility Model Content

[0005] In view of this, the present application provides a sensor component and a vehicle, which helps to reduce the interference of stray light in the external environment on the lidar module and improve the detection accuracy of the lidar module.

[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. The first side of the first bracket is provided with a fixing part and a mounting part, and the fixing part is connected to the windshield.

[0010] The second bracket is located on the second side of the first bracket and is connected to the first bracket;

[0011] A lidar module, wherein the lidar module is mounted on the second bracket;

[0012] The mounting section is also equipped with a light shield, which is used to reduce stray light entering the external environment of the lidar module.

[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. A sunshade on the first bracket blocks stray light from the external environment, preventing it from entering the LiDAR module and reducing interference from external light, thereby improving the module's detection accuracy.

[0014] In one possible implementation of this application, the mounting part forms a gap with the windshield, and the mounting part is provided with a first through hole and a second through hole; the lidar module includes a lidar and a camera, the lidar is disposed in the first through hole, and the camera is disposed in the second through hole; the light shield is disposed around the second through hole, and the light shield is used to reduce stray light from the external environment entering the camera.

[0015] In this embodiment of the lidar module, the lidar and camera are respectively disposed within the first and second through holes on the mounting portion. A gap is formed between the mounting portion and the windshield, thereby preventing interference between the lidar and camera and the windshield. By placing a light shield on the outer periphery of the camera, stray light can be prevented from entering the camera, thereby reducing interference from stray light in the external environment on the lidar module and improving the detection accuracy of the lidar module.

[0016] In one possible implementation of this application, the light shield includes a first light shield, a second light shield, and a third light shield. The first light shield is located on the side of the camera facing the fixing part, and the second and third light shields are both connected to the first light shield and are located on both sides of the camera, respectively.

[0017] This application embodiment uses a first light-shielding plate, a second light-shielding plate, and a third light-shielding plate that are interconnected to block stray light entering the camera from above and sides, allowing only laser signals at specific angles to enter the camera. This reduces the interference of stray light in the external environment on the lidar and improves the detection accuracy 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.

[0023] 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; at least one flange is provided at the end of the sidewall facing away from the mounting base plate, and at least one second mounting hole is provided on the flange;

[0025] 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.

[0026] The second fastener in this embodiment can be a bolt, screw, etc. After passing through the flange of the second bracket, the second fastener connects to the fixing post of the first bracket, thereby achieving a detachable connection between the first and second brackets, facilitating the installation and subsequent maintenance 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 and second brackets 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 and second brackets.

[0027] In one possible implementation of this application, a short-range camera is also included; a short-range camera mounting plate is further provided between the flange and the mounting base plate, and the short-range camera is detachably mounted on the short-range camera mounting plate;

[0028] The mounting part is also provided with a third through hole, through which the short-range camera is inserted.

[0029] This embodiment of the application mounts a short-range camera on a second bracket and passes the short-range camera through the first bracket, thereby providing the vehicle with accurate close-range environmental information through the short-range camera, supporting precise operation.

[0030] In one possible implementation of this application, the short-range camera mounting plate is provided with a plurality of third mounting holes and at least one third positioning hole;

[0031] The short-range camera is provided with multiple third fixing holes and at least one third positioning post, and the multiple third fixing holes correspond one-to-one with the multiple third mounting holes;

[0032] The third fastener passes through the third mounting hole and connects to the corresponding third fixing hole, and the third positioning pin passes through the third positioning hole.

[0033] The third fastener in this embodiment can be a bolt, screw, etc. After passing through the short-range camera mounting plate, the third fastener connects to the short-range camera, thus achieving a detachable connection between the short-range camera and the second bracket, facilitating the installation and subsequent maintenance of the short-range camera. By providing a third positioning post and a third positioning hole on the short-range camera mounting plate, the connection and positioning between the short-range camera and the second bracket can be achieved through the connection and cooperation between the third positioning post and the third positioning hole, which helps to improve the assembly efficiency of the short-range camera and the second bracket.

[0034] In one possible implementation of this application, the first side of the first bracket is further provided with an anti-light structure, the anti-light structure being located on the side of the lidar module and the short-range camera away from the fixing part, and the anti-light structure including a plurality of spaced protrusions.

[0035] This application embodiment provides an extinction structure on the side of the lidar module and short-range camera away from the fixed part. This extinction structure can further reduce stray light entering the external environment of the lidar module and short-range camera, which is beneficial to improving the detection accuracy and reliability of the lidar module and short-range camera.

[0036] This application also provides a vehicle including any of the sensor components described above.

[0037] 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. Furthermore, a sunshade can be used to block stray light from the external environment, preventing it from entering the lidar module and thus reducing interference from external light, thereby improving the detection accuracy of the lidar module.

[0063] As described in the background section, in related technologies, after the lidar is placed inside the windshield, the lidar may be affected by stray light from the external environment during use, which may affect the detection accuracy of the lidar.

[0064] In view of this, the present application aims to provide a sensor assembly and vehicle, which uses a light shield on a first bracket to block stray light in the external environment, thereby preventing stray light from entering the lidar module, reducing the interference of stray light in the external environment on the lidar module, and improving the detection accuracy of the lidar module.

[0065] 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.

[0066] 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 disposed inside the windshield. The lidar module is used to detect objects in the vehicle's surrounding environment to achieve assisted driving functions.

[0067] Please refer to Figures 1-12 ,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 viewpoint from inside the vehicle looking towards the front of the vehicle. This application provides a sensor assembly, including:

[0068] The windshield 100 can be fixed to the front of the cockpit by adhesive bonding.

[0069] The first bracket 200 is located on the side of the windshield 100 facing the interior of the vehicle. The first bracket 200 can be connected to the windshield 100 by means of adhesive bonding, snap-fitting, etc. The first side of the first bracket 200 (i.e. the side facing the windshield) is provided with a fixing part 210 and a mounting part 220, and the fixing part 210 is connected to the windshield 100.

[0070] The second bracket 300 is located on the second side of the first bracket 200 (i.e., the side facing away from the windshield) and is connected to the first bracket 200. The second bracket 300 can be connected and fixed to the first bracket 200, for example, by means of snap-fit ​​or bolt connection.

[0071] The lidar module 400 is mounted on the second bracket 300. The lidar module 400 can be connected and fixed to the second bracket 300 by means of snap-fit, bolt connection or other methods.

[0072] Please refer to Figure 5 In this embodiment, the mounting part 220 is also provided with a light shield 230, which is used to reduce stray light entering the external environment of the lidar module 400.

[0073] 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 a light shield 230 on the first bracket 200, stray light from the external environment is blocked, preventing it from entering the lidar module 400. This reduces interference from stray light in the external environment and improves the detection accuracy of the lidar module 400.

[0074] Specifically, in this embodiment of the application, the mounting portion 220 forms a gap with the windshield 100 (e.g., Figure 4 As shown, the specific size of this gap can be set as needed. This gap ensures that the lidar module does not interfere with the windshield 100 and maintains a suitable distance. The mounting part 220 is provided with a first through hole 221 and a second through hole 222.

[0075] The lidar module 400 includes a lidar 410 and a camera 420. The lidar 410 is used to emit and receive laser beams, and the camera 420 can collect image data of the exterior of the vehicle. The lidar 410 is inserted into a first through-hole 221, and the camera 420 is inserted into a second through-hole 222, so that the lidar 410 and the camera 420 can collect information through the windshield 100.

[0076] The light shield 230 is disposed around the second through hole 222. It can be understood that the light shield 230 protrudes from the mounting part 220, and the specific protrusion size can be set based on conditions such as the angle of light blocking. The light shield 230 can be disposed around the second through hole 222, or it can be disposed on only one or more sides of the second through hole 222.

[0077] In this embodiment, the lidar 410 and camera 420 of the lidar module 400 are respectively disposed within the first through hole 221 and the second through hole 222 on the mounting portion 220. A gap is formed between the mounting portion 220 and the windshield 100, thereby preventing interference between the lidar 410 and camera 420 of the lidar module 400 and the windshield 100. By placing the light shield 230 on the outer periphery of the camera 420, stray light can be prevented from entering the camera 420, thereby reducing the interference of stray light in the external environment on the lidar module 400 and improving the detection accuracy of the lidar module 400.

[0078] Please continue to refer to Figure 5The light shield 230 of this embodiment includes a first light shield 231, a second light shield 232, and a third light shield 233. The first light shield 231 is located on the side of the camera 420 facing the fixing part 210, that is, above the camera 420. The second light shield 232 and the third light shield 233 are both connected to the first light shield 231 and are located on both sides of the camera 420, that is, the second light shield 232 and the third light shield 233 are located on the left and right sides of the camera 420, respectively. The first light shield 231, the second light shield 232, and the third light shield 233 are used together to reduce stray light from the external environment entering the camera 420.

[0079] This embodiment of the application sets up a first light-shielding plate 231, a second light-shielding plate 232, and a third light-shielding plate 233 that are connected to each other, so as to block stray light entering the camera 420 from above and sides, and only allow laser signals at specific angles to enter the camera 420, thereby reducing the interference of stray light in the external environment on the lidar 410 and improving the detection accuracy of the lidar module 400.

[0080] In this embodiment, the fixing part 210 is bonded to the windshield 100, and the first bracket 200 and the second bracket 300 are detachably connected. Preferably, the first bracket 200 in this embodiment can be made of plastic, and the first bracket 200 and its structure, such as the sunshade 230, can be integrally molded by injection molding, thereby improving production efficiency. The fixing part 210 of the first bracket 200 can be bonded to the windshield 100 with adhesive. The second bracket 300 can also be made of plastic, and the second bracket 300 can also be integrally molded by injection molding. The second bracket 300 and the first bracket 200 can be detachably connected by snap-fit, bolt connection, or other methods.

[0081] The adhesive bonding method used in this embodiment connects the first bracket 200 and the windshield 100, which improves assembly efficiency. The detachable connection between the first bracket 200 and the second bracket 300 facilitates the installation and subsequent maintenance disassembly of the lidar module 400.

[0082] Please continue to refer to Figures 7-9The second bracket 300 in this embodiment includes a mounting base 310, which has a plurality of first mounting holes 311, each of which may be a through hole penetrating the mounting base 310. The lidar module 400 has a plurality of first fixing holes 430, which may be threaded holes, and each of the first fixing holes 430 corresponds one-to-one with the plurality of first mounting holes 311. A first fastener 510 passes through the first mounting hole 311 and connects to the corresponding first fixing hole 430. Exemplarily, the mounting base 310 in this embodiment has a generally rectangular projection, and four first mounting holes 311 are provided on the mounting base 310, respectively located near the four corners of the mounting base 310. The lidar module 400 includes a housing, and four first fixing holes 430 are correspondingly provided on one side of the housing. The first fastener 510 may be a bolt or a screw.

[0083] The mounting base plate 310 is further provided with at least one first positioning post 312, and the lidar module 400 is provided with at least one first positioning hole 440, with the first positioning post 312 passing through the first positioning hole 440. Exemplarily, the mounting base plate 310 of this embodiment may be provided with two first positioning posts 312, which are respectively positioned close to two first mounting holes 311 located diagonally opposite each other. The outer casing of the lidar module 400 is correspondingly provided with two first positioning holes 440, which are located diagonally opposite each other on one side of the outer casing.

[0084] In this embodiment, the first fastener 510 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 312 and a first positioning hole 440 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 312 and the first positioning hole 440, which helps to improve the assembly efficiency of the lidar module 400 and the second bracket 300.

[0085] Please continue to refer to Figure 7 , Figure 8 and Figure 10 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. At least one flange 330 is provided at the end of the sidewall 320 facing away from the mounting substrate 310, and at least one second mounting hole 331 is provided on the flange 330. The second mounting hole 331 can be a through hole. For example, as... Figure 8As shown, a flange 330 is provided on the left side wall 320 and two flanges 330 are provided on the right side wall 320. Each flange 330 is provided with a second mounting hole 331, that is, the second bracket 300 is provided with three second mounting holes 331, and the three second mounting holes 331 are arranged in a triangle.

[0086] The second side of the first bracket 200 is provided with at least two fixing posts 240, and the fixing posts 240 are provided with second fixing holes 241, which can be threaded holes. For example, as shown... Figure 11 As shown, the second side of the first bracket 200 is provided with three fixing posts 240 arranged in a triangle, and each fixing post 240 has a second fixing hole 241. The second fastener 520 passes through the second mounting hole 331 and connects to the second fixing hole 241. The second fastener 520 can be a bolt or a screw.

[0087] In this embodiment, the second fastener 520 passes through the flange 330 of the second bracket 300 and connects to the fixing post 240 of the first bracket 200, thereby realizing the detachable connection between the first bracket 200 and the second bracket 300, which facilitates the installation and subsequent maintenance and disassembly of the second bracket 300.

[0088] Furthermore, 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 250, which passes through the second positioning hole 332. For example, as shown... Figure 8 As shown in the figure, in this embodiment, a second positioning hole 332 is provided on the flange 330 on the left side of the figure, and a second positioning hole 332 is also provided on one of the two flanges 330 on the right side of the figure, that is, the second bracket 300 is provided with two second positioning holes 332. Correspondingly, as Figure 9 As shown, the first bracket 200 is also provided with two matching second positioning posts 250.

[0089] In this embodiment of the application, a second positioning hole 332 is provided on the second bracket 300, and a second positioning post 250 is provided 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 250 and the second positioning hole 332, which is beneficial to improving the assembly efficiency of the first bracket 200 and the second bracket 300.

[0090] Please continue to refer to Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 10This application embodiment also includes a short-range camera 600. A short-range camera mounting plate 340 is further provided between the flange 330 and the mounting substrate 310. Exemplarily, the short-range camera mounting plate 340 can be disposed... Figure 8 The left-side flange 330 is shown between the flange and the mounting base plate 310. The short-range camera 600 is detachably mounted on the short-range camera mounting plate 340, which facilitates installation and subsequent maintenance and disassembly.

[0091] The mounting section 220 is also provided with a third through hole 223, through which a short-range camera 600 is inserted, so that it can collect external environmental information through the windshield 100.

[0092] In this embodiment, by mounting the short-range camera 600 on the second bracket 300 and having the short-range camera 600 pass through the first bracket 200, the short-range camera 600 can provide the vehicle with accurate close-range environmental information, thus supporting precise operation.

[0093] Specifically, the short-range camera mounting plate 340 of this application embodiment is provided with a plurality of third mounting holes 341 and at least one third positioning hole 342.

[0094] The short-range camera 600 is provided with multiple third fixing holes 610 and at least one third positioning post 620, and the multiple third fixing holes 610 correspond one-to-one with the multiple third mounting holes 341.

[0095] For example, such as Figure 8 As shown, the short-range camera mounting plate 340 has two third mounting holes 341 and two third positioning holes 342. The two third mounting holes 341 are arranged diagonally, and the two third positioning holes 342 are also arranged diagonally. Figure 10 As shown, the short-range camera 600 is provided with two third fixing holes 610 and two third positioning posts 620. The two third fixing holes 610 are arranged diagonally, and the two third positioning posts 620 are also arranged diagonally. The third fastener passes through the third mounting hole 341 and connects to the corresponding third fixing hole 610. The third positioning post 620 passes through the third positioning hole 342.

[0096] The third fastener in this embodiment can be a bolt, screw, etc. After passing through the short-range camera mounting plate 340, the third fastener connects to the short-range camera 600, thereby achieving a detachable connection between the short-range camera 600 and the second bracket 300, facilitating the installation and subsequent maintenance disassembly of the short-range camera 600. By providing a third positioning hole 342 and a third positioning post 620 on the short-range camera 600, the connection and positioning between the short-range camera 600 and the second bracket 300 can be achieved through the connection and cooperation between the third positioning hole 342 and the third positioning post 620, which helps to improve the assembly efficiency of the short-range camera 600 and the second bracket 300.

[0097] Please continue to refer to Figure 5 and Figure 6 In this embodiment of the application, the first side of the first bracket 200 is also provided with a light-absorbing structure 260. The light-absorbing structure 260 is located on the side of the lidar module 400 and the short-range camera 600 away from the fixing part 210. The light-absorbing structure 260 includes a plurality of spaced protrusions, which can be dot-shaped or strip-shaped.

[0098] In this embodiment, an extinction structure 260 is provided on the side of the lidar module 400 and the short-range camera 600 away from the fixing part 210. This extinction structure 260 can further reduce stray light entering the external environment of the lidar module 400 and the short-range camera 600, which is beneficial to improving the detection accuracy and reliability of the lidar module 400 and the short-range camera 600.

[0099] Please refer to Figure 12 The sensor assembly of this application embodiment can be assembled in the following manner. First, the first bracket 200 is connected and fixed to the windshield 100; the lidar module 400 and the short-range camera 600 are connected and fixed to the second bracket 300, and then the first bracket 200 and the second bracket 300 are connected and fixed to form the sensor assembly of this application embodiment.

[0100] This application also provides a vehicle including the aforementioned sensor assembly.

[0101] 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. Furthermore, a sunshade can be used to block stray light from the external environment, preventing it from entering the LiDAR module's camera and thus reducing interference from external light, thereby improving the detection accuracy of the LiDAR module.
