[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to a Chinese patent application filed with the China Patent Office on August 11, 2023, with application number 2023110077047 and titled “Vehicle, LiDAR Mounting Frame and Mounting Structure Thereof,” and the entire contents of the patent application are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of laser radar installation technology, and in particular to a vehicle, a laser radar mounting frame and an installation structure thereof. Background Art

[0004] With the rapid development of autonomous driving technology, according to the "Automotive Driving Automation Classification" standard classification, the autonomous driving levels are divided into L0 (emergency assistance), L1 (partial driving assistance), L2 (combined driving assistance), L3 (conditional autonomous driving), L4 (highly autonomous driving) and L5 (fully autonomous driving). The current industry development trend is that vehicles above L2 level are equipped with multiple sensors such as cameras and laser radar (LiDAR).

[0005] LiDAR scans the surrounding environment by rapidly and repeatedly emitting laser beams to obtain "point cloud" data reflecting the shape, position, and movement of one or more objects in the surrounding environment. The laser wavelengths emitted by LiDAR used on vehicles are 905nm and 1550nm. The advantage of lasers is that they are focused so that they do not diverge over long distances. However, this makes it impossible to bypass obstacles and can be greatly disturbed or even inoperable in rainy, foggy, windy, and sandy weather. Therefore, the market trend and demand is to fully integrate the LiDAR installed on the outside of the vehicle in related technologies into the vehicle interior, especially on the inner surface of the front windshield.

DETAILED DESCRIPTION

[0049] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0050] There are many technical difficulties in fully integrating the laser radar installed on the outside of the vehicle in the related technology into the interior surface of the front windshield glass. The inventors have found that the reason for this problem is that the conventional technical means is to directly install the laser radar on the traditional windshield camera bracket. Compared with the vehicle-mounted camera, the laser radar is larger in size and weight, which makes the installation stability of the laser radar poor. When the laser radar is working, the built-in galvanometer mechanism of the laser radar vibrates at a high frequency, and the high-frequency vibration of the galvanometer mechanism emits high-frequency point cloud waves. The laser radar will directly transmit the vibration energy to the windshield camera bracket, thereby causing a large resonance noise.

[0051] Based on the above reasons, the present application provides a vehicle, a laser radar mounting bracket and its mounting structure, which can play a better vibration reduction role, improve torsional strength, and reduce noise.

[0052] Referring to Figures 1 to 5, Figure 1 shows a schematic structural diagram of a laser radar 30 installed on a laser radar mounting frame according to an embodiment of the present application. Figure 2 shows a cross-sectional structural diagram of a laser radar 30 installed on a laser radar mounting frame according to an embodiment of the present application. Figure 3 shows an enlarged structural schematic diagram of Figure 2 at point A. Figure 4 shows an enlarged structural schematic diagram of Figure 2 at point B. Figure 5 shows a schematic diagram of the mounting structure 10 of the laser radar mounting frame according to an embodiment of the present application. An embodiment of the present application provides a mounting structure 10 of a laser radar mounting frame, and the mounting structure 10 of the laser radar mounting frame includes: a rigid support portion 11, an elastic support portion 12 and a first connecting member 13. The rigid support portion 11 is used to be arranged on the bracket body 20. The elastic support portion 12 is fixedly connected to the rigid support portion 11. The first connecting member 13 is used to be connected to the laser radar 30, and the first connecting member 13 is embedded in the elastic support portion 12.

[0053] The mounting structure 10 of the above-mentioned laser radar mounting frame, when in use, has the effect of reducing vibration and noise because the first connecting member 13 is connected to the rigid support part 11 through the elastic support part 12; in addition, since the first connecting member 13 and the elastic support part 12 are embedded in the elastic support part 12, the elastic support part 12 is fixedly connected to the rigid support part 11, and can also play an anti-torsion role, so that the installation stability of the laser radar 30 on the laser radar mounting frame is better, meeting the requirement that the vibration noise of the laser radar installed in the vehicle cabin is ≤30dB.

[0054] Referring to Figures 3 and 5 , in some embodiments, the first connector 13 includes, but is not limited to, various mechanical parts such as nuts, screws, bolts, pins, rivets, and clips. Furthermore, the first connector 13 can be either metal or non-metallic, and can be flexibly adjusted and configured based on actual needs, and is not limited herein.

[0055] Please refer to Figures 8 to 11. Figure 8 shows a schematic diagram of the mounting structure 10 of a laser radar mounting bracket according to another embodiment of the present application. Figure 9 shows a cross-sectional view of Figure 8 taken at position DD. Figure 10 shows a schematic diagram of the rigid support portion 11 in the structure shown in Figure 8. Figure 11 shows a schematic diagram of the first connector 13 in the structure shown in Figure 8. In some embodiments, a first anti-slip portion 131 is provided on the outer wall of the first connector 13, the elastic support portion 12 is circumferentially arranged around the outer wall of the first connector 13, and a second anti-slip portion 121 is provided on the inner wall of the elastic support portion 12 to mate with the first anti-slip portion 131. Specifically, since the first anti-slip portion 131 is provided on the outer wall of the first connector 13, while the elastic support portion 12 is formed by injection molding an elastic material onto the exterior of the connector to form the elastic support portion 12, a second anti-slip portion 121 can be formed on the inner wall of the elastic support portion 12 to mate with the first anti-slip portion 131. In this way, when the first anti-slip part 131 and the second anti-slip part 121 cooperate with each other, the torsional resistance of the first connecting member 13 can be increased, that is, the torsional resistance of the laser radar 30 is increased, and the installation stability of the laser radar 30 on the laser radar mounting frame is improved.

[0056] In some embodiments, the first anti-slip portion 131 and the second anti-slip portion 121 may also be assembled and matched with each other through pre-manufactured shapes to achieve the purpose of increasing the anti-torsion ability.

[0057] Optionally, the elastic support portion 12 is connected to the first connector 13 by adhesive bonding, for example. Specifically, an adhesive material is applied to the contact surface between the first anti-slip portion 131 and the second anti-slip portion 121, thereby stably connecting and fixing the first anti-slip portion 131 and the second anti-slip portion 121, thereby increasing the anti-torsion capability of the first connector 13.

[0058] Optionally, the first anti-slip portion 131 includes but is not limited to various regular structures or other irregular structures such as a plurality of serrations, protrusions, and recessed holes sequentially arranged around the outer wall of the first connecting member 13 .

[0059] Of course, as some optional solutions, the outer wall of the first connecting member 13 can be set as a smooth surface, and the inner wall of the elastic support portion 12 can be set as a corresponding smooth surface. In this case, the torsion resistance is achieved based on the bonding force between the outer wall material of the first connecting member 13 and the inner wall material of the elastic support portion 12 injection-molded on the outer surface thereof.

[0060] Referring to Figures 8 to 11 , in some embodiments, the first connector 13 is provided with a first anti-detachment portion 132. The first anti-detachment portion 132 is circumferentially disposed around the outer wall of the first connector 13. This ensures a more secure connection between the first connector 13 and the elastic support portion 12, effectively preventing the first connector 13 from falling off the LiDAR mounting bracket when the LiDAR 30 is driven by external forces, thereby improving installation stability.

[0061] Referring to Figures 8 to 11 , in some embodiments, the first anti-slip portion 132 includes, but is not limited to, various protruding structures such as flanges, ribs, and bumps disposed on the outer wall of the first connector 13. Furthermore, the first anti-slip portion 132 can be flexibly adjusted and disposed at any position on the outer wall of the first connector 13 according to actual needs, such as at any end, the middle, or other locations of the first connector 13. Of course, as an alternative, the first anti-slip portion 132 on the outer wall of the first connector 13 can be omitted.

[0062] Please refer to Figures 3 to 6. In some embodiments, the mounting structure 10 further includes a second connecting member 14. The second connecting member 14 is embedded in the elastic support portion 12 and is spaced apart from the first connecting member 13. The space is filled with the elastic material of the elastic support portion 12, so that the first connecting member 13 and the second connecting member 14 are not in direct physical contact, thereby preventing the vibration energy of the laser radar 30 from being directly transmitted to the second connecting member 14 through the first connecting member 13, thereby achieving a vibration reduction and noise reduction effect. In addition, the first connecting member 13, the second connecting member 14 and the elastic support portion 12 are integrally injection molded, and the elastic support portion 12 is connected to the rigid support portion 11 through the second connecting member 14. In this way, the second connecting member 14 can effectively connect the elastic support portion 12 and the rigid support portion 11 together.

[0063] The specific structure of the second connecting member 14 is similar to that of the first connecting member 13 and will not be described in detail here.

[0064] 3 and 5 , in one embodiment, the rigid support portion 11 defines a first mounting hole 111 and a third connecting member 15 embedded in the first mounting hole 111 . The third connecting member 15 is detachably connected to the second connecting member 14 .

[0065] The specific structure of the third connecting member 15 is similar to that of the first connecting member 13, and may include, but is not limited to, various mechanical parts such as nuts, screws, bolts, studs, pins, rivets, and clips. The specific selection of these parts is not detailed here. As a specific example, the second connecting member 14 is a screw, and the third connecting member 15 is a nut that adapts to the screw. This facilitates assembly and disassembly of the second connecting member 14 from the third connecting member 15, as well as replacement and maintenance.

[0066] Referring to Figures 3 and 5 , in one embodiment, the third connector 15 is specifically, for example, integrally injection-molded with the rigid support portion 11. Furthermore, an anti-slip portion is provided on the outer wall of the third connector 15, and a corresponding anti-slip portion is provided on the inner wall of the rigid support portion 11 where it contacts the third connector 15. This ensures that the third connector 15 is securely positioned within the rigid support portion 11, providing enhanced torsional resistance. The specific form of this anti-slip portion is similar to the first anti-slip portion 131 described in the aforementioned embodiment and will not be further described here.

[0067] Please refer to Figures 4, 6 and 7. In another embodiment, the second connecting member 14 is embedded in the rigid support portion 11 and is integrally injection molded with the rigid support portion 11. In this way, the first connecting member 13, the elastic support portion 12, the second connecting member 14 and the rigid support portion 11 are set as an integrated structure, which not only has a good vibration reduction and noise reduction effect, but also has a strong torsion resistance. Specifically, during production, the first connecting member 13, the second connecting member 14 and the elastic support portion 12 are firstly integrally molded to obtain a vibration reduction structure, and then the second connecting member 14 of the vibration reduction structure and the rigid material are integrally injection molded through a mold to obtain a rigid support portion 11 connected to the second connecting member 14. In addition, the second connecting member 14 is provided with a head 141 and a rod 142 connected to the head 141. The head 141 is embedded and fixed in the elastic support portion 12, and the rod 142 is embedded and fixed in the rigid support portion 11. Both the head portion 141 and the rod portion 142 are, for example, structures extending in the axial direction Z. Their respective axial cross-sections can be flexibly adjusted and configured according to actual needs, including but not limited to regular and irregular shapes such as circular, elliptical, and polygonal. In this example, the axial cross-section of the rod portion 142 is, for example, a regular polygon, specifically a regular hexagon, which has strong torsional resistance.

[0068] Referring to Figures 8 to 11 , in some embodiments, the elastic support portion 12 includes a first mounting portion 122 and a second mounting portion 123 connected to the first mounting portion 122. The first connector 13 is embedded in the first mounting portion 122, while the second mounting portion 123 is embedded in the rigid support portion 11. Thus, the second mounting portion 123 is embedded within the rigid support portion 11 and securely connected thereto; the first mounting portion 122 is located outside the rigid support portion 11, effectively reducing vibration and noise during operation of the laser radar 30.

[0069] Referring to Figures 8 to 11 , in one embodiment, a positioning plate 112 is provided on the inner wall of the rigid support portion 11. The positioning plate 112 is provided with at least one glue injection hole 1121. The positioning plate 112 is embedded and fixed in the second mounting portion 123. Thus, since the positioning plate 112 is embedded and fixed in the second mounting portion 123, it prevents the second mounting portion 123 from being stably connected and fixed to the rigid support portion 11, preventing it from becoming loose.

[0070] Referring to Figures 8 to 11 , in one embodiment, a plurality of injection holes 1121 are provided, spaced sequentially around the central axis of the rigid support portion 11. This, on the one hand, facilitates a secure connection between the second mounting portion 123 and the soft materials on both sides of the rigid support portion 11 by pulling against each other. On the other hand, during the injection molding process, the more injection holes 1121 are provided, the easier it is for the injection material to pass through the injection holes 1121 and fill the mold, so that both opposing sides of the positioning plate 112 are covered with injection material, allowing the second mounting portion 123 to be completely wrapped around the exterior of the positioning plate 112, thereby enhancing the connection stability and improving the efficiency of the injection molding process.

[0071] Referring to Figures 8 to 11 , in one embodiment, a protrusion 1122 is provided on the positioning plate 112. A third anti-slip portion is provided on the outer wall of the protrusion 1122. The protrusion 1122 is embedded in the second mounting portion 123, which is provided with a fourth anti-slip portion that is compatible with the third anti-slip portion. In this manner, the third and fourth anti-slip portions cooperate to increase the torsional resistance between the elastic support portion 12 and the rigid support portion 11, ensuring that the torsional resistance of the connector is no less than 2.5 N / M. Furthermore, the bond area is increased, effectively preventing the second mounting portion 123 from separating from the rigid support portion 11. Furthermore, the rigidity of the protrusion 1122 is enhanced.

[0072] Specifically, the protrusion 1122 is disposed at, for example, the middle portion or other positions of the positioning plate 112 .

[0073] Similar to the first anti-slip portion 131 , the third anti-slip portion includes but is not limited to various regular structures or other irregular structures such as multiple serrations, bumps, and recessed holes sequentially arranged on the outer wall of the first connecting member 13 .

[0074] Referring to FIG. 8 to FIG. 11 , in one embodiment, the elastic support portion 12 , the first connecting member 13 and the rigid support portion 11 are integrally formed by injection molding.

[0075] Specifically, the elastic support portion 12 is formed by soft plastic injection molding, and the rigid support portion 11 is formed by hard plastic injection molding.

[0076] Please refer to FIG. 8 to FIG. 11 . In one embodiment, the elastic support portion 12 includes but is not limited to rubber, specifically natural rubber, with a hardness of 55HRC-70HRC, for example.

[0077] Specifically, setting the hardness of the elastic support portion 12 to 55HRC-70HRC can achieve a balance between rigidity and noise reduction. When the hardness of the elastic support portion 12 is less than 55HRC, due to the relatively soft material, the mounting support rigidity is insufficient, failing to meet the requirement of an absolute value of the angular error of the installation positioning radar window of less than 1°. When the hardness of the elastic support portion 12 is greater than 70HRC, the excessive hardness of the material leads to insufficient vibration energy absorption, resulting in a vibration noise level exceeding 30dB, which cannot meet the requirements of LiDAR.

[0078] In addition, the rigid support portion 11 includes but is not limited to the use of PBT material. In order to avoid the occurrence of resonance, the material selection of the rigid support portion 11 has frequency avoidance modal requirements: specifically, avoiding the modal frequency of 200Hz-400Hz. In some embodiments, the modal frequency of the rigid support portion 11 ranges from 70Hz-150Hz. In some embodiments, the modal frequency of the rigid support portion 11 ranges from 100Hz-180Hz. Within the determined hardness range of the elastic support portion 12, the use of the modal frequency in the above range can control the noise level within 30dB to meet the use requirements of the lidar.

[0079] Referring to Figures 8 to 11 , in one embodiment, a fifth anti-slip portion 1231 is provided on the outer wall of the second mounting portion 123, and a sixth anti-slip portion 113 is provided on the inner wall of the rigid support portion 11 to accommodate the fifth anti-slip portion 1231. Thus, the interaction between the fifth anti-slip portion 1231 and the sixth anti-slip portion 113 increases the torsional resistance between the elastic support portion 12 and the rigid support portion 11, ensuring that the torsional resistance of the connector is no less than 2.5 N / M. Furthermore, the increased bonding area effectively prevents the second mounting portion 123 from separating from the rigid support portion 11, further enhancing the rigidity of the second mounting portion 123 and the rigid support portion 11.

[0080] Optionally, the fifth anti-slip portion 1231 includes but is not limited to various regular structures or other irregular structures such as multiple serrations, bumps, and recessed holes sequentially arranged on the outer wall of the second mounting portion 123 .

[0081] Please refer to Figures 1 to 5. In one embodiment, a laser radar mounting bracket includes at least one mounting structure 10 of any of the above embodiments, and also includes a bracket body 20. The rigid support portion 11 is provided on the bracket body 20.

[0082] It should be noted that the "rigid support part 11" can be a "part of the bracket body 20", that is, the "rigid support part 11" and the "other parts of the bracket body 20" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the bracket body 20", that is, the "rigid support part 11" can be manufactured independently and then combined with the "other parts of the bracket body 20" into a whole.

[0083] When the above-mentioned laser radar mounting frame is in use, the first connecting member 13 is connected to the rigid support part 11 through the elastic support part 12, which plays a role in reducing vibration and noise; in addition, since the first connecting member 13 and the elastic support part 12 are injection-molded as one piece and embedded in the elastic support part 12, the elastic support part 12 is fixedly connected to the rigid support part 11, and can also play an anti-torsion role, so that the installation stability of the laser radar 30 on the laser radar mounting frame is better.

[0084] Please refer to Figure 1. In some embodiments, there are multiple mounting structures 10, and the multiple mounting structures 10 are connected to the laser radar 30 together, and a gap is set between the laser radar 30 and other positions of the laser radar mounting frame. In this way, the connection between the laser radar 30 and the laser radar mounting frame is a flexible connection, which can achieve better vibration reduction and noise reduction effects.

[0085] Referring to Figures 1 to 5 , in one embodiment, a vehicle includes a laser radar mounting bracket according to any of the above embodiments, a laser radar 30, and a vehicle window glass (not shown). The laser radar mounting bracket is mounted on the inner side of the vehicle window glass (i.e., the side closer to the vehicle interior), and the laser radar 30 is mounted on the laser radar mounting bracket, which is connected to the mounting structure 10.

[0086] In the above-mentioned vehicle, since the first connecting member 13 is connected to the rigid support part 11 through the elastic support part 12, it plays a role in reducing vibration and noise; in addition, since the first connecting member 13 is embedded in the elastic support part 12, the elastic support part 12 is fixedly connected to the rigid support part 11, and it can also play an anti-torsion role, so that the installation stability of the laser radar 30 on the laser radar mounting frame is better.

[0087] Among them, the mounting surface of the vibration-damping BOSS mounting column of the bracket is designed to be level with the ground to ensure that the FOV window of the laser radar 30 is effective. After installation, the installation position error of the laser radar 30 in the vehicle body coordinate system should be less than 5mm, and the absolute value of the angle error should be less than 1°.

[0088] In one embodiment, the laser radar 30 faces the vehicle window glass, and the detection signals emitted and received by the laser radar 30 pass through the vehicle window glass.

Furthermore, the docking portion 31 is provided with a second mounting hole 3111 corresponding to the locking member 32. The locking member 32 passes through the second mounting hole 3111 and connects to the first connecting member 13, thereby locking the docking portion 31 to the mounting structure 10.

[0093] Please refer to Figures 2 to 5. In one embodiment, the docking portion 31 is provided on the side of the laser radar 30; the docking portion 31 includes a docking bottom wall 311, and the docking bottom wall 311 is provided with a second mounting hole 3111. The locking member 32 passes through the second mounting hole 3111 and is connected to the first connecting member 13. The top end surface of the first connecting member 13 is in contact with the docking bottom wall 311. In this way, the top end surface of the first connecting member 13 and the docking bottom wall 311 are in contact with each other to limit the laser radar 30 in the Z-axis direction. The locking member 32 passes through the second mounting hole 3111 and is connected to the first connecting member 13, which can achieve a stable connection between the laser radar 30 and the laser radar mounting frame, prevent rigid contact between the laser radar 30 and the laser radar mounting frame, and effectively reduce vibration noise.

[0102] In the related art, after the laser radar 30 is installed on the laser radar mounting frame, the vibration of the laser radar 30 is transmitted through the laser radar mounting frame. After the protective cover 40 is connected to the bracket body 20, a gap is inevitably left. When the bracket body 20 vibrates, the protective cover 40 will vibrate, causing noise. Based on this, in this embodiment, a vibration-damping pad 50 is provided at the connection between the protective cover 40 and the bracket body 20. In this way, the protective cover 40 is connected to the bracket body 20 through the vibration-damping pad 50. The contact between the protective cover 40 and the bracket body 20 is not rigid contact, but flexible contact. The vibration-damping pad 50 plays a vibration-damping role, thereby effectively reducing vibration noise.

[0103] Please refer to Figure 15. In one embodiment, the vibration-damping pad 50 includes but is not limited to felt or TPE soft rubber with a thickness of 1 mm, which fills the gap and has flexible soft contact to absorb vibration energy and achieve vibration reduction and noise reduction effects.

[0104] Referring to Figures 14 and 15 , in one embodiment, the protective cover 40 is connected to the bracket body 20 by a snap-fit ​​connection. The bracket body 20 is provided with a first snap-fit ​​portion 21, and the protective cover 40 is provided with a second snap-fit ​​portion 41 that cooperates with the first snap-fit ​​portion 21. The first snap-fit ​​portion 21 and the second snap-fit ​​portion 41 are snap-fitted to each other. A vibration-damping pad 50 is disposed between the first snap-fit ​​portion 21 and the second snap-fit ​​portion 41.
