[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0034] Please refer to the following: Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a vehicle 100 provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a partial cross-sectional view of the vehicle 100 in the first embodiment. Figure 3 yes Figure 1 The vehicle 100 shown is a cross-sectional structural schematic diagram from another angle in the first embodiment.

[0035] The vehicle 100 provided in the embodiments of this application may be, but is not limited to, a sedan, truck, pickup truck, commercial vehicle, bus, and SUV; this application makes no limitation thereto. The vehicle 100 includes a body 110, window glass 120, a lidar 130, a lidar bracket 170, a camera assembly 140, a shield 150, and a rearview mirror assembly 160. The body 110 serves to provide a safe, comfortable, and convenient driving environment for the occupants.

[0036] The vehicle window 120, LiDAR bracket 170, camera assembly 140, and shield 150 are all mounted on the vehicle body 110. The vehicle window 120 is installed at the opening of the vehicle body 110, and the vehicle body 110 and the vehicle window 120 together form the interior space of the vehicle. In this embodiment, the vehicle window 120 may be, but is not limited to, a windshield, rear windshield, side window, A-pillar glass, B-pillar glass, etc. For example, the vehicle window 120 may be a windshield. The LiDAR 130, LiDAR bracket 170, camera assembly 140, and shield 150 are all located within the vehicle interior space.

[0037] Both the LiDAR 130 and the camera assembly 140 are important sensors on the vehicle 100. The LiDAR 130 is mounted on the LiDAR bracket 170, facing the vehicle window 120. The detection signals emitted and received by the LiDAR 130 pass through the vehicle window 120. Specifically, the detection signals emitted by the LiDAR 130 can pass through the vehicle window 120 to detect the external environment of the vehicle 100. The portion of the detection signal reflected by objects in the external environment can pass through the vehicle window 120 again and be received by the LiDAR 130, thus enabling the LiDAR 130 to perceive information about the external environment of the vehicle 100. The wavelength of the detection signal of the LiDAR 130 can be, for example, 905nm or 1550nm. The camera assembly 140 is used to capture and identify information about the external environment of the vehicle 100, enabling functions such as vehicle recognition, pedestrian recognition, and lane line recognition. The cover 150 is used to cover the LiDAR bracket 170, LiDAR 130, and camera assembly 140 to improve the aesthetics of the interior of the vehicle 100. The rearview mirror assembly 160 is fixedly mounted on the visor 150. Passengers or drivers can obtain environmental information behind the vehicle 100 through the rearview mirror assembly 160.

[0038] In this embodiment, the lidar bracket 170 is made of metal or thermoplastic resin. The metal can be iron, zinc, aluminum, stainless steel, or other metallic or alloy materials. For example, the lidar bracket 170 is made of zinc alloy. The thermoplastic resin can be polybutylene terephthalate (PBT), nylon 66 (PA66), or thermoplastic elastomer (TPE), among other materials.

[0039] Please refer to the following: Figure 4 and Figure 5 , Figure 4 yes Figure 3 A schematic diagram of the structure of the lidar bracket 170 of the vehicle 100 shown. Figure 5 yes Figure 4 The top view of the lidar bracket 170 shown.

[0040] For ease of description, the forward direction of vehicle 100 is defined as the X-axis, the width direction of vehicle 100 as the Y-axis, and the height direction of vehicle 100 as the Z-axis. The X-axis, Y-axis, and Z-axis are mutually perpendicular. "Looking down" refers to observing the lidar bracket 170 along the negative Z-axis. After the lidar 130 is mounted on the lidar bracket 170, the lidar 130 faces the vehicle window 120 along the X-axis.

[0041] The lidar bracket 170 includes a base plate 21, a side plate 22, and a fixing plate 23, with the side plate 22 fixedly connected between the base plate 21 and the fixing plate 23. The side plate 22 is substantially perpendicular to the base plate 21, and the fixing plate 23 is substantially perpendicular to the side plate 22. Preferably, the base plate 21, side plate 22, and fixing plate 23 are integrally formed, i.e., integrally formed from a single metal plate through processes such as stamping or forging, or integrally formed using metal casting or resin injection molding.

[0042] exist Figure 4 In this configuration, one end of the side plate 22 is fixedly connected to the peripheral side of the base plate 21, and the side plate 22 and the base plate 21 enclose a box space (not shown in the figure). The lidar 130 is fixedly connected to the base plate 21 and located within the box space. Specifically, the bottom surface of the lidar 130 is fixed to the base plate 21, and the side surface of the lidar 130 can abut against the side plate 22. The base plate 21 and the side plate 22 achieve fixed installation of the lidar 130 and protect the lidar 130 from external damage.

[0043] In this embodiment, the substrate 21 includes a first surface 211, a second surface 212, and a peripheral surface (not shown in the figure). The first surface 211 and the second surface 212 are arranged opposite to each other along the thickness direction of the substrate 21 (the Z-axis direction in the figure). The first surface 211 is used to support the lidar 130. The ratio of the area of ​​the first surface 211 to the area of ​​the lidar 130 facing the first surface 211 is between 0.5 and 1.5 to ensure that the substrate 21 can stably support the lidar 130. The peripheral surface connects the first surface 211 and the second surface 212. The peripheral surface may include a first surface 215 and a second surface 216. For example, the second surface 216 is arranged adjacent to the first surface 215. In some other embodiments, the first surface 215 and the second surface 216 may also be spaced apart and arranged opposite to each other along the width direction of the substrate 21.

[0044] The substrate 21 also has at least three mounting through holes 213 and at least one damping through hole 214. Each mounting through hole 213 and damping through hole 214 penetrates the first surface 211 and the second surface 212 of the substrate 21 along the thickness direction (Z-axis direction in the figure). Each mounting through hole 213 and damping through hole 214 is spaced apart from each other. At least three mounting through holes 213 are arranged around the periphery of the substrate 21 and are spaced apart from each other. The damping through hole 214 is located in the middle of the substrate 21. It can be understood that, on the one hand, by providing the damping through hole 214 on the substrate 21, the weight of the lidar bracket 170 can be reduced; on the other hand, since the lidar 130 will generate vibrations of a certain frequency during operation, the damping through hole 214 on the substrate 21 can prevent the lidar 130 from resonating with the lidar bracket 170, thereby achieving the effect of vibration reduction and noise reduction.

[0045] In some embodiments, the ratio of the area of ​​the opening of the damping through-hole 214 to the area of ​​the first surface 211 of the substrate 21 is between 1 / 4 and 2 / 3. In this embodiment, the ratio of the area of ​​the opening of the damping through-hole 214 to the area of ​​the first surface 211 of the substrate 21 can be adjusted according to the NVH value of the lidar 130. Preferably, when the NVH value of the lidar 130 is equal to or greater than 25 dB, the ratio of the area of ​​the opening of the damping through-hole 214 to the area of ​​the first surface 211 of the substrate 21 is between 1 / 2 and 2 / 3. Preferably, when the NVH value of the lidar 130 is less than 25 dB, the ratio of the area of ​​the opening of the damping through-hole 214 to the area of ​​the first surface 211 of the substrate 21 is between 1 / 4 and 1 / 2. It should be noted that NVH is an abbreviation for Noise, Vibration, and Harshness. The NVH value of LiDAR 130 refers to the comprehensive value of various indicators such as noise, vibration and comfort.

[0046] Please refer to the following: Figures 6 to 8 , Figure 6 yes Figure 4 The front view of the lidar bracket 170 shown is shown. Figure 7 yes Figure 4 The right view of the lidar bracket 170 shown. Figure 8 yes Figure 4 The left view of the lidar bracket 170 shown.

[0047] One end of the side plate 22 is fixedly connected to the peripheral side surface of the substrate 21 and extends circumferentially along the substrate 21. The side plate 22 and the substrate 21 enclose a box space (not shown in the figure). The side plate 22 includes a first sub-side plate 221, a second sub-side plate 222, and a third sub-side plate 223. The first sub-side plate 221 is fixedly connected to the first side surface 215 of the substrate 21, and the second sub-side plate 222 is fixedly connected to the second side surface 216 of the substrate 21. The third sub-side plate 223 is fixedly connected between the first sub-side plate 221 and the second sub-side plate 222, and is spaced apart from the substrate 21. It is understood that because the third sub-side plate 223 is spaced apart from the substrate 21, the weight of the lidar bracket 170 can be reduced, and the lidar bracket 170 can be easily integrally manufactured.

[0048] A fixing plate 23 is fixedly connected to the other end of the side plate 22 away from the substrate 21. The fixing plate 23 extends in a direction away from the housing space. For example, along the thickness direction of the side plate 22, the fixing plate 23 extends in a direction away from the substrate 21. The fixing plate 23 is used to fixably connect to the inner side of the vehicle body 110 of the vehicle 100. The fixing plate 23 includes a first fixing plate 231 and a second fixing plate 232. The first fixing plate 231 is fixedly connected to the other end of the first sub-side plate 221 away from the substrate 21. The first fixing plate 231 extends in a direction away from the housing space. For example, along the thickness direction of the first sub-side plate 221 (the X-axis direction in the diagram), the first fixing plate 231 extends in a direction away from the first sub-side plate 221. The second fixing plate 232 is fixedly connected to the other end of the second sub-side plate 222 away from the substrate 21. The second fixing plate 232 extends in a direction away from the housing space. For example, along the thickness direction of the second sub-side plate 222 (Y-axis direction in the figure), the second fixing plate 232 extends in a direction away from the second sub-side plate 222.

[0049] The fixing plate 23 is also provided with a plurality of fixing holes 23a, which correspond one-to-one with a plurality of mating holes on the vehicle body 110. Specifically, the plurality of fixing holes 23a includes at least one first fixing hole 233 and at least two second fixing holes 234. At least one first fixing hole 233 is provided on the first fixing plate 231. Each first fixing hole 233 penetrates the first fixing plate 231 along its thickness direction (Z-axis direction in the figure). Each first fixing hole 233 communicates with a first mating hole on the vehicle body 110. For example, there are two first fixing holes 233. The two first fixing holes 233 are spaced apart along the length direction (Y-axis direction in the figure) of the first fixing plate 231. In some other embodiments, there may be one, three, or more than three first fixing holes 233.

[0050] At least one second fixing hole 234 is provided in the second sub-side plate 222. Each second fixing hole 234 penetrates the second fixing plate 232 along the thickness direction (Z-axis direction in the figure). Each second fixing hole 234 communicates with a second mating hole of the vehicle body 110. Exemplarily, there is one second fixing hole 234. In some other embodiments, there may be two or more second fixing holes 234.

[0051] Please refer to it again. Figure 2 and Figure 3When the lidar 130 is mounted on the lidar bracket 170, the lidar 130 is fixedly connected to the substrate 21 and located within the housing space. Specifically, the lidar 130 is fixedly connected to the first surface 211 of the substrate 21 and at least partially covers the shock-absorbing through-hole 214. Exemplarily, the lidar 130 is detachably mounted to the first surface 211 of the substrate 21. In this embodiment, the lidar 130 is generally rectangular, and its housing is made of metal. Exemplarily, the laser wavelength of the lidar 130 can be 1550nm or 905nm. Furthermore, the lidar 130 weighs 500 grams or more, and / or its volume is 300mm * 200mm * 50mm or more. The lidar 130 is used to detect external environmental information of the vehicle 100.

[0052] The lidar 130 has at least three mounting holes (not shown in the figure), which are arranged around the periphery of the lidar 130 and spaced apart from each other. Each mounting hole communicates with a first fixing hole 233 of the lidar bracket 170. For example, there are four mounting holes.

[0053] The vehicle 100 also includes at least three mounting members 130a for fixing the lidar 130 and the lidar bracket 170. Each mounting member 130a is mounted in a mounting through hole 213 on the base plate 21 and a mounting hole on the lidar 130. In this embodiment, the at least three mounting members 130a can be bolts or screws. It should be understood that both screw connections and bolt connections are threaded connections. In other words, the lidar 130 and the lidar bracket 170 can be fixed by a threaded connection. It is understood that threaded connections have advantages such as easy installation, convenient disassembly, and simple operation, which helps to achieve a detachable connection between the lidar 130 and the lidar bracket 170. For example, when the lidar 130 and the lidar bracket 170 are fixed by a bolt connection, a shock-absorbing bolt is usually used. It should be understood that a shock-absorbing bolt consists of two screws and a rubber post. The rubber post is located between the two screws, and the two screws are coaxially arranged. The screw has a screw head larger than its diameter, which is embedded in a rubber column. The end face of the screw head near the thread is flush with or slightly protruding from the end face of the rubber column. Furthermore, the rubber column can be sufficiently large or thick. Under external force, the rubber column undergoes plastic deformation, absorbing the energy of the force. The bolt has high strength and rigidity, capable of withstanding the deformation of the rubber column and external impacts, thus preventing resonance between the lidar 130 and the lidar bracket 170, thereby providing vibration damping.

[0054] In some other embodiments, the lidar 130 and the lidar bracket 170 can also be fixed by riveting, and the lidar bracket 170 and the vehicle body 110 can also be fixed by riveting. It should be understood that riveting is a method of fixing metal structural parts or assemblies together using rivets. Commonly used rivets include closed-head blind rivets, closed-head countersunk blind rivets, open-head blind rivets, and open-head countersunk blind rivets.

[0055] In this embodiment, after the lidar 130 is mounted on the lidar bracket 170 via the mounting member 130a, the lidar bracket 170 is fixedly mounted on a suitable location within the vehicle body 110 of the vehicle 100, for example, on the roof crossbeam. The first fixing plate 231 and the second fixing plate 232 of the lidar bracket 170 are both fixedly connected to the inner side of the vehicle body 110. For example, the first fixing plate 231 and the second fixing plate 232 of the lidar bracket 170 are both in contact with the roof crossbeam of the vehicle body 110.

[0056] In addition, the vehicle 100 also includes a plurality of fasteners 101. The plurality of fasteners 101 are used to secure the lidar bracket 170 to the vehicle body 110. Each fastener 101 is mounted in a mounting hole 23a of the lidar bracket 170. Specifically, each fastener 101 includes at least one first fastener 102 and at least one second fastener (not shown). For example, both the at least one first fastener 102 and the at least one second fastener can be bolts. Specifically, each first fastener 102 is mounted in a first mounting hole 233 of a first mounting plate 231, and each second fastener is mounted in a second mounting hole 234 of a second mounting plate 232.

[0057] Please continue reading. Figure 3 In this embodiment, the camera assembly 140 is located on at least one side of the lidar bracket 170 and is spaced apart from the lidar bracket 170. The camera assembly 140 includes a camera bracket 30 and a camera 40, with the camera 40 mounted on the camera bracket 30. The camera bracket 30 has a receiving cavity 31, which is used to accommodate the camera 40. The shape of the receiving cavity 31 can be determined according to the outer contour of the camera 40. The camera bracket 30 also has at least three mounting holes 32. Each mounting hole 32 communicates with a fastening hole in the vehicle body 110. For example, there are two camera assemblies 140, which are spaced apart on opposite sides of the lidar bracket 170. Specifically, the two camera brackets 30 are spaced apart on opposite sides of the lidar bracket 170. In some other embodiments, the camera bracket 30 may also be fixedly connected to the lidar bracket 170.

[0058] In this embodiment, the vehicle 100 also includes a plurality of fasteners 103. The plurality of fasteners 103 are used to secure the camera bracket 30 to the vehicle body 110, thereby fixing the camera assembly 140 to the vehicle body 110. For example, the plurality of fasteners 103 can be screws. Specifically, each fastener 103 is installed in a mounting hole 32 of the camera bracket 30. With this configuration, the LiDAR 130 and the camera assembly 140 can be assembled together, facilitating the use of the LiDAR 130 in conjunction with the camera 40, thereby enabling more comprehensive acquisition of information about the surrounding environment of the vehicle 100 and further improving the performance of the vehicle 100.

[0059] In this embodiment, the shield 150 can be made of plastics such as polypropylene (PP), polybutylene terephthalate (PBT), or nylon 66 (PA66). For example, the shield 150 is made of polypropylene (PP). The rearview mirror assembly 160 is fixedly installed on the side of the shield 150 facing away from the lidar bracket 170 and the camera assembly 140. Specifically, the rearview mirror assembly 160 includes a rearview mirror bracket 50 and a rearview mirror (not shown), with the rearview mirror mounted on the rearview mirror bracket 50. The rearview mirror bracket 50 is fixedly installed on the side of the shield 150 facing away from the lidar 130 and the camera assembly 140. For example, the rearview mirror bracket 50 is made of zinc alloy. The rearview mirror bracket 50 and the shield 150 can be fixed together using adhesive tape. In some other embodiments, the rearview mirror bracket 50 and the shield 150 can also be fixed together using threaded connections; this embodiment does not limit the scope of this application.

[0060] In some other embodiments, the rearview mirror assembly 160 is an electronic display screen. The electronic display screen is embedded in the visor 150. The electronic display screen can be used to display images and provide passengers or the driver with information about the environment behind the vehicle 100. In this configuration, the electronic display screen functions as a rearview mirror, eliminating the need for an additional rearview mirror inside the vehicle 100, thus saving installation space inside the vehicle 100.

[0061] Please see Figure 9 , Figure 9 yes Figure 1 The diagram shows a partial structural schematic of the vehicle 100 in the second embodiment.

[0062] The vehicle 100 shown in this embodiment differs from the vehicle 100 shown in the first embodiment above in that the rearview mirror assembly 160 further includes a mounting part 60, which is fixedly mounted on the lidar bracket 170. Specifically, the mounting part 60 is fixedly mounted on the second surface 212 of the base plate 21. In this embodiment, the mounting part 60 can be made of metal. For example, the material of the mounting part 60 is cast aluminum alloy. The mounting part 60 is used to mount the rearview mirror bracket 50. Specifically, the mounting part 60 includes two fixing parts 61 and an assembly part 62. The two fixing parts 61 are fixedly connected to the second surface 212 of the base plate 21 and are spaced apart on opposite sides of the shock-absorbing through hole 214 of the base plate 21. The assembly part 62 is fixedly connected between the two fixing parts 61.

[0063] In this embodiment, the shielding cover ( Figure 9 A clearance hole (not shown) is provided, penetrating the cover along its thickness and protruding from the assembly 60. The clearance hole is used to allow clearance for the rearview mirror bracket 50. The rearview mirror bracket 50 is fixedly mounted on the surface of the assembly 60 opposite to the lidar bracket 170. The rearview mirror bracket 50 passes through the clearance hole in the cover and extends out of the cover. Specifically, the rearview mirror bracket 50 is fixedly mounted on the second surface 212 of the assembly 60 opposite to the base plate 21. With this configuration, the rearview mirror assembly 160 can be integrated with the lidar bracket 170, reducing the length of the rearview mirror bracket 50 extending outside the cover, thereby saving installation space inside the vehicle 100.

[0064] The lidar bracket 170 provided in this application integrates the lidar 130 inside the vehicle 100 and is located inside the window glass 120, preventing external environmental factors such as dust and sand from affecting the detection of the lidar 130. This improves the detection accuracy of the lidar 130 and ensures better detection performance. Simultaneously, it reduces the operating noise and vibration of the lidar 130, meeting the overall NVH performance requirements of the vehicle 100. Furthermore, since the lidar bracket 170 is made of metal, and both the lidar 130's housing and the vehicle body 110 are also made of metal, heat accumulated inside the shield 150 can be conducted through the lidar 130's housing to the lidar bracket 170, then through the lidar bracket 170 to the vehicle body 110, and finally through the vehicle body 110 to the external environment. The heat is then carried away by airflow, thus enabling the lidar bracket 170 to achieve heat dissipation.
