Abstract
Description
Technical Field
[0001] (Cross - reference to Related Applications) This disclosure claims the priority of a Chinese patent application with the application number 2023110077047 and the title "Vehicle, Laser Radar Mounting Bracket and Its Mounting Structure", which was filed with the China National Intellectual Property Administration on August 11, 2023, and all of its contents are incorporated into this disclosure by reference.
[0002] This application relates to the technical field of laser radar mounting, and particularly to vehicles, laser radar mounting brackets and their mounting structures.
Background Art
[0003] With the rapid development of autonomous driving technology, based on the "Automated Driving Level" standard classification, the autonomous driving levels are classified into L0 (Emergency Assistance), L1 (Partial Driving Assistance), L2 (Combined Driving Assistance), L3 (Conditional Autonomous Driving), L4 (High - level Autonomous Driving) and L5 (Full Autonomous Driving). Currently, as a development trend in the industry, vehicles at L2 level and above are equipped with multiple sensors such as cameras and lidar (LiDAR).
[0004] Lidar can emit laser beams at high speed and repeatedly to scan the surrounding environment and obtain "point cloud" data that reflects the shape, position and movement of one or more objects in the surrounding environment. The wavelengths of the lasers emitted by lidars used in vehicles are 905nm and 1550nm. The advantage of lasers is that they can be focused so as not to diverge even over long distances, but thereby they cannot bypass obstacles, and are greatly interfered with and even rendered inoperable under weather conditions such as rain, fog and sandstorms. Therefore, the market trend and needs are to fully integrate the lidar that was previously mounted outside the vehicle inside the vehicle, particularly on the inner surface of the front windshield.

[0029] To provide a clearer and easier understanding of the above-mentioned objectives, features, and advantages of the present application, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Many specific details are provided in the following description to facilitate a complete understanding of the present application. However, the present application can be implemented in many forms other than those described herein, and those skilled in the art can make similar improvements without preserving the spirit of the present application; therefore, the present application is not limited to the specific embodiments disclosed below.
[0030] In related technologies, there are many technical difficulties in completely integrating the laser radar, which was previously mounted externally to the vehicle, onto the interior side of the front window glass. Research by the inventor has shown that the cause of these problems is that, in conventional technologies, the laser radar is directly attached to the conventional front camera bracket. Compared to the onboard camera, the size and weight of the laser radar are both larger, making the mounting stability of the laser radar poor. Furthermore, when the laser radar is operating, the mirror scanning mechanism built into the laser radar vibrates at a high frequency, and high-frequency point wave waves are emitted through the high-frequency vibration of the mirror scanning mechanism. The laser radar then conducts vibration energy directly to the front camera bracket, thereby causing significant resonance noise.
[0031] For the reasons stated above, this invention provides a vehicle, laser radar mounting bracket, and mounting structure thereof that exhibit excellent vibration damping, improve torsional rigidity, and reduce noise.
[0032] Referring to Figures 1 to 5, Figure 1 shows a schematic diagram of the structure of a laser radar 30 according to one embodiment of the present application, installed on a laser radar mounting bracket. Figure 2 shows a cross-sectional diagram of the laser radar 30 according to one embodiment of the present application, installed on a laser radar mounting bracket. Figure 3 shows an enlarged schematic diagram of part A in Figure 2. Figure 4 shows an enlarged schematic diagram of part B in Figure 2. Figure 5 shows a schematic diagram of the mounting structure 10 of the laser radar mounting bracket according to one embodiment of the present application. The mounting structure 10 of the laser radar mounting bracket provided by one embodiment of the present application includes a rigid support part 11, an elastic support part 12, and a first connecting member 13. The rigid support part 11 is provided on the bracket body 20. The elastic support part 12 is fixed and connected to the rigid support part 11. The first connecting member 13 is for connecting to the laser radar 30, and the first connecting member 13 is fitted into the elastic support part 12.
[0033] The mounting structure 10 of the laser radar mounting bracket described above exhibits vibration and sound dampening effects when in use, because the first connecting member 13 is connected to the rigid support part 11 via the elastic support part 12. Furthermore, since the first connecting member 13 is fitted into the elastic support part 12 and the elastic support part 12 is fixed and connected to the rigid support part 11, torsional rigidity is also exhibited, resulting in good mounting stability of the laser radar 30 on the laser radar mounting bracket, and meeting the requirement that vibration noise when the laser radar is installed in the vehicle interior be 30 dB or less.
[0034] Referring to Figures 3 and 5, in some embodiments, the first connecting member 13 includes, but is not limited to, various mechanical parts such as nuts, bolts, screws, studs, pins, rivets, and engaging members. Furthermore, the first connecting member 13 may be a metal or non-metal part, and is flexibly adjusted and set according to actual requirements, and is not limited thereto.
[0035] Referring to Figures 8 to 11, Figure 8 shows a schematic diagram of a mounting structure 10 for a laser radar mounting bracket according to yet another embodiment of the present application. Figure 9 shows a cross-sectional structure diagram along the DD line in Figure 8. Figure 10 shows a schematic diagram of the structure of the rigid support portion 11 in the structure shown in Figure 8. Figure 11 shows a schematic diagram of the structure of the first connecting member 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 connecting member 13, and an elastic support portion 12 is installed circumferentially surrounding the outer wall of the first connecting member 13, and a second anti-slip portion 121 is provided on the inner wall of the elastic support portion 12 that matches the first anti-slip portion 131. Specifically, since the first anti-slip portion 131 is provided on the outer wall of the first connecting member 13, an elastic support portion 12 can be obtained by injection molding an elastic material onto the outside of the connecting member, and at the same time, a second anti-slip portion 121 that fits together with the first anti-slip portion 131 can be formed on the inner wall of the elastic support portion 12. In this way, when the first anti-slip portion 131 and the second anti-slip portion 121 fit together, the torsional rigidity of the first connecting member 13, i.e., the torsional rigidity of the laser radar 30, can be increased, and the mounting stability of the laser radar 30 on the laser radar mounting bracket can be improved.
[0036] In some embodiments, the first anti-slip portion 131 and the second anti-slip portion 121 can be mounted together via pre-manufactured, mutually matching shapes to achieve the objective of increasing torsional rigidity.
[0037] Selectively, the elastic support portion 12 and the first connecting member 13 are connected by bonding, for example, with an adhesive. Specifically, an adhesive material is applied to the contact surfaces of 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, and increasing the torsional rigidity of the first connecting member 13.
[0038] Selectively, the first anti-slip portion 131 includes, but is not limited to, a variety of regular structures such as multiple sawtooth teeth, protrusions, recessed holes, or other irregular structures sequentially installed around the outer wall of the first connecting member 13.
[0039] Of course, as one of several possible solutions, the outer wall of the first connecting member 13 may be set to a smooth surface, for example, and the inner wall of the elastic support portion 12 may be set to a smooth surface accordingly. In this case, torsional rigidity 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 which is injection molded to the outside of it.
[0040] Referring to Figures 8 to 11, in some embodiments, the first connecting member 13 is provided with a first anti-detachment portion 132. The first anti-detachment portion 132 is installed circumferentially, surrounding the outer wall of the first connecting member 13. In this way, the first anti-detachment portion 132 makes the connection between the first connecting member 13 and the elastic support portion 12 relatively strong, effectively preventing the first connecting member 13 from detaching from the laser radar mounting bracket when the laser radar 30 is subjected to an external force, thereby improving mounting stability.
[0041] Referring to Figures 8 to 11, in some embodiments, the first anti-detachment portion 132 includes, but is not limited to, various protruding structures such as flanges, ribs, and projections provided on the outer wall of the first connecting member 13. Furthermore, the first anti-detachment portion 132 can be flexibly adjusted and set at any position on the outer wall of the first connecting member 13, for example, at any end, center, or other part of the first connecting member 13, as required by practical needs. Of course, as one of several options, the first anti-detachment portion 132 on the outer wall of the first connecting member 13 may be omitted.
[0042] Referring 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 fitted into the elastic support portion 12 and is positioned at a distance from the first connecting member 13. This distance is filled with the elastic material of the elastic support portion 12, preventing the first connecting member 13 and the second connecting member 14 from directly coming into physical contact, thereby preventing the vibration energy of the laser radar 30 from being directly transmitted to the second connecting member 14 via the first connecting member 13, and thus providing vibration damping and sound dampening effects. Furthermore, 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 via 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.
[0043] Here, the specific structural form of the second connecting member 14 is similar to that of the first connecting member 13, and therefore will not be explained again here.
[0044] Referring to Figures 3 and 5, in one embodiment, the rigid support portion 11 is provided with a first mounting hole 111 and a third connecting member 15 fitted inside the first mounting hole 111, and the third connecting member 15 is detachably connected to the second connecting member 14.
[0045] Here, the specific structural form of the third connecting member 15 is similar to that of the first connecting member 13 and includes, but is not limited to, various mechanical parts such as nuts, bolts, screws, studs, pins, rivets, and engaging members, and how to specifically select them will not be explained again here. As one specific example, the second connecting member 14 is set to a bolt, and the third connecting member 15 is set to a nut that is compatible with the bolt, making it easy to attach, detach, replace, and repair the second connecting member 14 on the third connecting member 15.
[0046] Referring to Figures 3 and 5, in one embodiment, the third connecting member 15 is specifically, for example, injection-molded integrally with the rigid support portion 11. Furthermore, an anti-slip portion is provided on the outer wall of the third connecting member 15, and a corresponding anti-slip portion is provided on the inner wall of the rigid support portion 11 that contacts the third connecting member 15, so that the third connecting member 15 is stably installed in the rigid support portion 11 and the torsional rigidity is increased. The specific form of this anti-slip portion is similar to that of the first anti-slip portion 131 in the above-described embodiment and will not be described again here.
[0047] Referring to Figures 4, 6, and 7, in other embodiments, the second connecting member 14 is fitted into the rigid support portion 11 and is injection molded integrally 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 up as an integrated structure, which not only has excellent vibration damping and sound damping effects but also strong torsional rigidity. In specific manufacturing, first, the three components of the first connecting member 13, the second connecting member 14, and the elastic support portion 12 are integrally molded to obtain a vibration damping structure. Then, the second connecting member 14 of the vibration damping structure and the rigid material are integrally injection molded using a mold to obtain a rigid support portion 11 connected to the second connecting member 14. Furthermore, the second connecting member 14 is provided with a head portion 141 and a rod portion 142 connected to the head portion 141, the head portion 141 is fitted and fixed into the elastic support portion 12, and the rod portion 142 is fitted and fixed into the rigid support portion 11. The head portion 141 and the rod portion 142 are both structures that extend along the axial direction Z, for example, and their respective axial cross-sections are flexibly adjusted and set according to actual requirements, and include, but are not limited to, regular and irregular shapes such as circles, ellipses, and polygons. In this example, the axial cross-section of the rod portion 142 is, for example, a regular polygon, specifically, a regular hexagon, and has strong torsional rigidity.
[0048] 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 connecting member 13 is fitted into the first mounting portion 122, and the second mounting portion 123 is fitted into the rigid support portion 11. In this way, the second mounting portion 123 is fitted inside the rigid support portion 11 and stably connected to the rigid support portion 11, while the first mounting portion 122 is located outside the rigid support portion 11, exhibiting excellent vibration damping and noise damping effects when the laser radar 30 is in operation.
[0049] 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, and at least one pouring hole 1121 is provided in the positioning plate 112, and the positioning plate 112 is fitted and fixed in the second mounting portion 123. In this way, because the positioning plate 112 is fitted and fixed in the second mounting portion 123, it exhibits a fall prevention effect, and the second mounting portion 123 is stably connected and fixed in the rigid support portion 11, making it less likely to loosen.
[0050] Referring to Figures 8 to 11, in one embodiment, multiple injection holes 1121 are provided and are installed sequentially at intervals around the central axis of the rigid support portion 11. In this way, on the one hand, the flexible materials on both sides of the second mounting portion 123 and the rigid support portion 11 are pulled together to facilitate a strong connection. On the other hand, in the injection molding process, the more injection molding material is provided, the easier it is for the injection molding material to pass through the injection holes 1121 and fill the inside of the mold. This ensures that the injection molding material is present on both sides of the positioning plate 112 that are facing away from each other, allowing the second mounting portion 123 to completely enclose the outside of the positioning plate 112, thereby increasing the stability of the connection and improving the efficiency of the injection molding process.
[0051] Referring to Figures 8 to 11, in one embodiment, the positioning plate 112 is provided with a protrusion 1122, the outer wall of the protrusion 1122 is provided with a third anti-slip portion, the protrusion 1122 is fitted into the second mounting portion 123, and the second mounting portion 123 is provided with a fourth anti-slip portion that fits the third anti-slip portion. In this way, by fitting the third anti-slip portion and the fourth anti-slip portion together, the torsional rigidity between the elastic support portion 12 and the rigid support portion 11 is increased, and the requirement that the torsional rigidity of the connecting member be 2.5 N·M or more can be satisfied. Furthermore, the bonding area is increased, effectively preventing the second mounting portion 123 from detaching from the rigid support portion 11. In addition, the rigidity performance of the protrusion 1122 can be enhanced.
[0052] Specifically, the protrusion 1122 is installed, for example, in the center of the positioning plate 112 or at another location.
[0053] Similar to the first anti-slip portion 131, the third anti-slip portion includes, but is not limited to, a variety of regular structures such as multiple sawtooth teeth, protrusions, recessed holes, or other irregular structures sequentially installed around the outer wall of the first connecting member 13.
[0054] Referring to Figures 8 to 11, in one embodiment, the elastic support portion 12, the first connecting member 13, and the rigid support portion 11 are integrally injection molded.
[0055] Specifically, the elastic support portion 12 is injection molded using soft rubber, and the rigid support portion 11 is injection molded using hard rubber.
[0056] Referring to Figures 8 to 11, in one embodiment, the elastic support portion 12 includes but is not limited to rubber; specifically, it is, for example, natural rubber, and its hardness is set to, for example, 55HRC-70HRC.
[0057] Specifically, by setting the hardness of the elastic support part 12 to 55HRC-70HRC, the requirements for rigidity and sound insulation can be met simultaneously. If the hardness of the elastic support part 12 is less than 55HRC, the material is relatively soft, resulting in insufficient mounting support rigidity and failing to meet the requirement that the absolute value of the mounting error of the laser radar field of view must be less than 1°. If the hardness of the elastic support part 12 exceeds 70HRC, the material is too hard, resulting in insufficient vibration energy absorption performance, which causes the vibration noise level to exceed 30dB, making it impossible to meet the requirements for using the laser radar.
[0058] Furthermore, the rigid support portion 11 is made of PBT material, but is not limited to this. To avoid the occurrence of resonance, there is a frequency avoidance requirement for the material selection of the rigid support portion 11, specifically avoiding mode frequencies of 200Hz-400Hz. In some embodiments, the mode frequency range of the rigid support portion 11 is 70Hz-150Hz. In some embodiments, the mode frequency range of the rigid support portion 11 is 100Hz-180Hz. By adopting mode frequencies within the above ranges within the determined hardness range of the elastic support portion 12, the noise level can be controlled to within 30dB, meeting the requirements for use with laser radar.
[0059] 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 that fits the fifth anti-slip portion 1231 is provided on the inner wall of the rigid support portion 11. In this way, by fitting the fifth anti-slip portion 1231 and the sixth anti-slip portion 113 together, the torsional rigidity between the elastic support portion 12 and the rigid support portion 11 is increased, satisfying the requirement that the torsional rigidity of the connecting member be 2.5 N·M or more. Furthermore, the bonding area is increased, effectively preventing the second mounting portion 123 from detaching from the rigid support portion 11. In addition, the rigidity performance of the second mounting portion 123 and the rigid support portion 11 can be enhanced.
[0060] Selectively, the fifth anti-slip portion 1231 includes, but is not limited to, a variety of regular structures such as multiple sawtooth teeth, protrusions, recessed holes, or other irregular structures sequentially installed around the outer wall of the second mounting portion 123.
[0061] Referring to Figures 1 to 5, in one embodiment, the laser radar mounting bracket includes at least one mounting structure 10 of any of the above embodiments, and further includes a bracket body 20, the rigid support portion 11 is provided on the bracket body 20.
[0062] Furthermore, this "rigid support part 11" may be "a part of the bracket body 20," meaning that the "rigid support part 11" may be integrally molded and manufactured with "other parts of the bracket body 20," or it may be an independent component that can be separated from "other parts of the bracket body 20," meaning that the "rigid support part 11" may be manufactured independently and then combined with "other parts of the bracket body 20" to form a single whole.
[0063] The laser radar mounting bracket described above exhibits vibration and sound dampening effects because, during use, the first connecting member 13 is connected to the rigid support portion 11 via the elastic support portion 12. Furthermore, since the first connecting member 13 is integrally injection molded with the elastic support portion 12 and fitted into the elastic support portion 12, and the elastic support portion 12 is fixed and connected to the rigid support portion 11, torsional rigidity is also exhibited, resulting in good mounting stability of the laser radar 30 on the laser radar mounting bracket.
[0064] Referring to Figure 1, in some embodiments, multiple mounting structures 10 are provided, and these multiple mounting structures 10 are jointly connected to the laser radar 30, with spacing between the laser radar 30 and other positions of the laser radar mounting bracket. In this way, the connection method between the laser radar 30 and the laser radar mounting bracket is flexible, enabling excellent vibration and sound insulation effects.
[0065] Referring to Figures 1 to 5, in one embodiment, the vehicle includes a laser radar mounting bracket as in any of the embodiments described above, and further includes a laser radar 30 and a window glass (not shown). The laser radar mounting bracket is attached to the inner surface of the window glass (i.e., the side closer to the interior of the vehicle), the laser radar 30 is mounted on the laser radar mounting bracket, and the laser radar 30 is connected to the mounting structure 10.
[0066] In the aforementioned vehicle, the first connecting member 13 is connected to the rigid support portion 11 via the elastic support portion 12, thereby exhibiting vibration damping and sound dampening effects. Furthermore, since the first connecting member 13 is fitted into the elastic support portion 12, and the elastic support portion 12 is fixed and connected to the rigid support portion 11, torsional rigidity is also exhibited, resulting in good mounting stability of the laser radar 30 on the laser radar mounting bracket.
[0067] Here, the mounting surface of the bracket's vibration-damping BOSS mounting column is horizontal to the ground, ensuring that the laser radar 30's field of view (FOV) is effective. After installation, the mounting position error of the laser radar 30 in the vehicle coordinate system must be less than 5 mm, and the absolute value of the angular error must be less than 1°.
[0068] In one embodiment, the laser radar 30 is directed towards the window glass, and the detection signals emitted and received by the laser radar 30 pass through the window glass.
[0069] Referring to Figures 1 to 5, in one embodiment, at least three mounting structures 10 are provided, and each laser radar 30 is connected to one of the individual mounting structures 10. A gap is provided between the laser radar 30 and the area on the laser radar mounting bracket other than the mounting structures 10. In this way, the laser radar 30 is installed on the laser radar mounting bracket via at least three mounting structures 10, and the connection method to the laser radar mounting bracket is flexible, achieving excellent vibration and sound insulation effects.
[0070] Referring to Figures 1 to 5, in one embodiment, one side of the laser radar 30 is mounted on at least two mounting structures 10, and the other side of the laser radar 30 is mounted on at least one mounting structure 10. In this way, since both opposing sides of the laser radar 30 are attached to and supported by the mounting structures 10, the mounting stability on the laser radar mounting bracket is strong.
[0071] Referring to Figures 2 to 5, in one embodiment, the laser radar 30 is provided with a connecting portion 31 and a fastening member 32 that fastens and fixes the connecting portion 31 onto the first connecting member 13.
[0072] Referring to Figures 2 to 5, in one embodiment, the first connecting member 13 is set to a nut, for example, and the fastening member 32 is set to a bolt or threaded rod that fits the nut. Furthermore, the connecting portion 31 is provided with a second mounting hole 3111 corresponding to the fastening member 32, and the fastening member 32 is connected to the first connecting member 13 by passing through the second mounting hole 3111, thereby fastening and attaching the connecting portion 31 to the mounting structure 10.
[0073] Referring to Figures 2 to 5, in one embodiment, the connecting portion 31 is provided on the side of the laser radar 30, the connecting portion 31 includes a connecting bottom wall 311, the connecting bottom wall 311 is provided with a second mounting hole 3111, and the fastening member 32 passes through the second mounting hole 3111 and is connected to the first connecting member 13. The top end face of the first connecting member 13 and the connecting bottom wall 311 are in close contact with each other. In this way, the top end face of the first connecting member 13 and the connecting bottom wall 311 are in close contact with each other, thereby achieving positional restriction of the laser radar 30 along the Z-axis direction, and the fastening member 32 passes through the second mounting hole 3111 and is connected to the first connecting member 13, thereby stably connecting the laser radar 30 to the laser radar mounting bracket, preventing rigid contact between the laser radar 30 and the laser radar mounting bracket, and effectively reducing vibration and noise.
[0074] Referring to Figures 3, 12, and 13, in one embodiment, the connection portion 31 further includes a connection side wall 312 connected to the connection bottom wall 311. The connection side wall 312 is provided with at least one first limiting member 3121 and at least one second limiting member 3122, and the first limiting member 3121 and the second limiting member 3122 each abut against the outer wall of the elastic support portion 12. In this way, the at least one first limiting member 3121 abuts against the outer wall of the elastic support portion 12, thereby limiting the position of the laser radar 30 along the X-axis direction, and the at least one second limiting member 3122 abuts against the outer wall of the elastic support portion 12, thereby limiting the position of the laser radar 30 along the Y-axis direction. As a result, the laser radar 30 is stably connected to the laser radar mounting bracket, rigid contact between the laser radar 30 and the laser radar mounting bracket is prevented, and vibration noise can be effectively reduced.
[0075] Referring to Figures 3, 12, and 13, in one embodiment, the first limiting member 3121 and the second limiting member 3122 are limiting ribs, limiting projections, or limiting blocks provided on the connecting side wall 312.
[0076] In this embodiment, both the first limiting member 3121 and the second limiting member 3122 are, for example, limiting ribs, and the direction in which the limiting ribs extend is parallel to the central axis of the rigid support portion 11.
[0077] Referring to Figures 3, 12, and 13, in one embodiment, connection parts 31 are provided on both opposing sides of the laser radar 30, with at least two connection parts 31 located on one side of the laser radar 30 and at least one connection part 31 located on the other side of the laser radar 30.
[0078] Referring to Figures 3, 12, and 13, in one embodiment, the first limiting member 3121 and the second limiting member 3122 are each provided with an assembly gap between them and the outer wall of the elastic support part 12, the assembly gap being, for example, 0.2 mm, thereby preventing assembly difficulties on the mounting structure 10 of the laser radar 30 due to manufacturing deviations.
[0079] Referring to Figures 3 and 12, in one specific embodiment, on one side of the laser radar 30, i.e., the right side as shown in Figure 12, there are, for example, two connection parts 31, and two first limiting members 3121 and two second limiting members 3122 are provided on each connection part 31, and are used for the primary positioning of the laser radar 30. Specifically, the two first limiting members 3121 each abut against opposite sides of the elastic support part 12 to achieve position restriction in the X-axis, and the two second limiting members 3122 each abut against opposite sides of the elastic support part 12 to achieve position restriction in the Y-axis.
[0080] Referring to Figures 3 and 13, further, on the other side of the laser radar 30, i.e., the left side shown in Figure 13, there are, for example, one or two connection portions 31, and one first limiting member 3121 and two second limiting members 3122 are provided on the connection portion 31, which are used for sub-positioning of the laser radar 30. Specifically, the two second limiting members 3122 each abut against the opposite sides of the elastic support portion 12 to achieve positional limitation in the Y-axis, and one first limiting member 3121 abuts against the outer wall of the elastic support portion 12 to achieve compensation in the X-axis direction, thereby absorbing manufacturing deviations of the laser radar 30 and ensuring that the laser radar 30 is smoothly connected to the laser radar mounting bracket.
[0081] Referring to Figures 14 and 15, in one embodiment, the vehicle further includes a protective cover 40 provided on the bracket body 20, the protective cover covering the outside of the laser radar 30 and providing protection to the laser radar 30. Here, the method of connecting the protective cover on the laser radar 30 includes, but is not limited to, connections via fastening members such as engagements, screws, pins, and rivets, and may be flexibly adjusted and set according to actual needs.
[0082] In related technologies, after the laser radar 30 is mounted on the laser radar mounting bracket, vibrations from the laser radar 30 are transmitted through the laser radar mounting bracket. After the protective cover 40 and the bracket body 20 are connected, a gap inevitably forms. When the bracket body 20 vibrates, it causes the protective cover 40 to vibrate, thereby generating noise. Based on this, in this embodiment, an anti-vibration pad member 50 is provided at the connection point between the protective cover 40 and the bracket body 20. In this way, the protective cover 40 is connected to the bracket body 20 via the anti-vibration pad member 50, and the contact between the protective cover 40 and the bracket body 20 is flexible contact, not rigid contact. The anti-vibration pad member 50 exerts an anti-vibration effect, thereby effectively reducing vibration noise.
[0083] Referring to Figure 15, in one embodiment, the vibration-damping pad member 50 includes, but is not limited to, a 1 mm thick felt or TPE soft rubber, and fills the gap and provides flexible soft contact, absorbing vibration energy and achieving vibration damping and sound insulation effects.
[0084] Referring to Figures 14 and 15, in one embodiment, the connection method between the protective cover 40 and the bracket body 20 is, for example, engagement. Here, a first engagement portion 21 is provided on the bracket body 20, and a second engagement portion 41 is provided on the protective cover 40 that engages with the first engagement portion 21, and the first engagement portion 21 and the second engagement portion 41 are engaged and connected to each other. The vibration-damping pad member 50 is installed between the first engagement portion 21 and the second engagement portion 41.
