The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0035] The lidar bracket 100 of the first aspect of the present invention is described below with reference to the accompanying drawings.

[0036] According to an embodiment of the present invention, a lidar bracket 100 is used to mount a lidar 200, such as... Figures 1-3As shown, the lidar bracket 100 is installed inside the windshield 2000 of a vehicle. The lidar bracket 100 includes a bracket body 1 and mounting feet 2 disposed on the bracket body 1. The bracket body 1 has a plate-like structure, and its upper surface is used to mount the lidar 200. The mounting feet 2 have mounting surfaces 2a, and the inner surface of the windshield 2000 has mounting mating surfaces 2000a that mate with the mounting surfaces 2a. The mounting surfaces 2a and the corresponding mounting mating surfaces 2000a are parallel to each other, and the mounting surfaces 2a and 2000a are in close contact, thereby allowing the bracket body 1 to extend horizontally.

[0037] The main body 1 of the bracket is a plate-shaped structure. The upper surface of the main body 1 is used to install the lidar 200. The upper surface of the main body 1 is flat, which can provide a flat installation reference for the lidar 200, making it easy to position and assemble the lidar 200.

[0038] Mounting feet 2 are mounted on the main body 1 of the bracket, with the mounting surface 2a of the mounting feet 2 facing the inner side of the windshield 2000. The main body 1 of the bracket is connected to the windshield 2000 via the mounting feet 2. The mounting feet 2 separate the main body 1 of the bracket from the windshield 2000, thus providing space for the placement of the lidar 200.

[0039] The inner surface of the windshield 2000 has a mounting mating surface 2000a that mates with the mounting surface 2a. The mounting surface 2a and the corresponding mounting mating surface 2000a are parallel to each other. That is, when there are multiple mounting feet 2, each mounting foot 2 corresponds to a different mounting mating surface 2000a. The mounting surface 2a of each mounting foot 2 is parallel to the inner surface of the windshield 2000 at the point where the mounting foot 2 is in contact with the windshield 2000. Thus, each mounting foot 2 can maintain a close contact with the windshield 2000.

[0040] Mounting surface 2a and mounting mating surface 2000a are closely connected and in contact with each other. On the one hand, the force borne by the bracket body 1 can be distributed to the windshield 2000 through mounting surface 2a, making the installation of the bracket body 1 more stable; on the other hand, mounting surface 2a and mounting mating surface 2000a can play a positioning role when they are in contact, which is beneficial to the rapid alignment of the lidar bracket 100 during assembly.

[0041] Since the mounting surface 2a and the corresponding mounting mating surface 2000a are parallel to each other and fit together, when the mounting leg 2 connects the bracket body 1 to the inner side of the windshield 2000, the mounting leg 2 simultaneously plays the role of positioning and installation, so that the bracket body 1 extends horizontally.

[0042] The bracket body 1 extends horizontally, and the upper surface for mounting the LiDAR 200 also remains horizontal. After the LiDAR 200 is mounted on the bracket body 1, the optical axis direction of the LiDAR 200 relative to the vehicle coordinate system is determined. This facilitates the LiDAR 200's detection field of view meeting design requirements and also facilitates its integration with other vehicle components. This reduces the workload of measuring and adjusting the attitude of each LiDAR 200 during the assembly stage and also reduces the amount of adjustment required in subsequent calibration work.

[0043] According to an embodiment of the present invention, the lidar bracket 100, by setting the mounting feet 2 on the bracket body 1 and making the mounting surface 2a of the mounting feet 2 parallel and closely connected to the mounting mating surface 2000a of the inner side of the windshield 2000, extends the bracket body 1 in the horizontal direction, thereby forming a horizontal mounting reference on the bracket body 1. This allows the mounting posture of the lidar 200 to be determined by the lidar bracket 100 itself during the assembly stage, which helps to reduce the workload of measurement, adjustment and calibration after assembly and can improve assembly efficiency.

[0044] In some embodiments of the present invention, such as Figure 2 As shown, there are at least two mounting feet 2, which are respectively placed on both sides of the bracket body 1 in the left and right directions.

[0045] It is worth noting that the left and right directions are based on the direction the vehicle is driving normally, with the direction the vehicle is moving forward as the front and the driver's perspective as the reference. The driver's left direction is the left direction, and the driver's right direction is the right direction.

[0046] The mounting legs 2 located on the left and right sides respectively support the bracket body 1 on both sides, distributing the load borne by the bracket body 1 to the mounting legs 2 on both sides. Compared to setting mounting legs 2 on only one side, setting mounting legs 2 on both sides of the bracket body 1 can improve assembly stability. Furthermore, the bracket body 1 is constrained in the left and right direction, and its rotation around the front and back direction is restricted, making it less likely for the bracket body 1 to tilt to one side.

[0047] It is worth noting that the mounting legs on the left and right sides can be arranged symmetrically or asymmetrically according to the internal space, as long as they can provide support for the left and right sides of the main body of the support frame 1.

[0048] By providing mounting feet 2 on both the left and right sides of the bracket body 1, the bracket body 1 is stably supported in the lateral direction, resulting in more accurate positioning and a more stable installation posture for the lidar 200. Simultaneously, the load borne by a single mounting foot 2 is reduced, and the connection between the mounting foot 2 and the windshield 2000 is less prone to loosening, thus improving installation stability.

[0049] In some embodiments of the present invention, such as Figure 2 As shown, the bracket body 1 has multiple mounting legs 2 on at least one side in the left-right direction, and the mounting legs 2 on the same side are spaced apart in the front-back direction.

[0050] Multiple mounting legs 2 on the same side are arranged at intervals in the front-to-back direction, with a gap between adjacent mounting legs 2. The bracket body 1 is supported at multiple positions in the front-to-back direction simultaneously. The gap between adjacent mounting legs 2 can be determined according to the size of the area on the bracket body 1 used for mounting other parts.

[0051] When the main body 1 of the bracket is subjected to vibration load in the front and rear directions, the two mounting legs 2 at the front and rear share the load, which can improve the installation stability of the lidar bracket 100.

[0052] Furthermore, by setting multiple mounting feet 2, the position of the bracket body 1 is determined by more contact parts, and the impact of deviation of a single contact part on the posture of the bracket body 1 is reduced accordingly. This further improves the positioning accuracy of the lidar bracket 100 and the consistency of the installation posture among different vehicles. In this way, the posture of the bracket body 1 in the front-rear direction is maintained, and the positioning of the lidar bracket 100 on the windshield 2000 is more accurate, which is conducive to maintaining the stability of the optical axis direction of the lidar 200.

[0053] In some embodiments of the present invention, multiple mounting feet 2 may be provided on both the left and right sides of the bracket body 1, that is, two or more mounting feet 2 spaced apart in the front-back direction are provided on the left and right sides of the bracket body 1 respectively.

[0054] In some embodiments of the present invention, such as Figures 1-3 As shown, the lidar bracket 100 is installed inside the windshield 2001 of the vehicle. There are four mounting feet 2. Two mounting feet 2 are respectively provided on the left and right sides of the bracket body 1. Among the mounting feet 2 on the same side, the angle between the mounting surface 2a of the mounting foot 2 on the front side and the horizontal plane is greater than the angle between the mounting surface 2a of the mounting foot 2 on the rear side and the horizontal plane.

[0055] The four mounting feet 2 are divided into two groups on the left and right sides of the bracket body 1. The two mounting feet 2 in the same group are spaced apart in the front and rear direction. The four mounting feet 2 form four support points on the inner side of the windshield 2001. The bracket body 1 is supported by the four support points. The position of the bracket body 1 is determined by the four mounting surfaces 2a.

[0056] This reduces the impact of deviations at individual contact points on the posture of the bracket body 1, further improving the positioning accuracy of the LiDAR bracket 100 and the consistency of installation posture across vehicles. The more accurate positioning of the LiDAR bracket 100 on the windshield 2001 helps maintain the stability of the LiDAR 200's optical axis. Furthermore, the force on the bracket body 1 is more evenly distributed in the front-rear direction, enhancing the stability of the LiDAR bracket 100 installation.

[0057] Understandably, the windshield 2001 is constructed as a curved surface in the longitudinal direction, and the angle of inclination of the sectional surface of the inner side of the windshield 2001 relative to the horizontal plane is not the same at different positions in the longitudinal direction. The angle between the mounting mating surface 2000a corresponding to the mounting bracket 2 on the front side and the horizontal plane is greater than the angle between the mounting mating surface 2000a corresponding to the mounting bracket 2 on the rear side and the horizontal plane.

[0058] Therefore, the angle between the mounting surfaces 2a of the two front mounting feet 2 and the horizontal plane is greater than the angle between the mounting surfaces 2a of the two rear mounting feet 2 and the horizontal plane. The angle between the mounting surfaces 2a and the horizontal plane is larger at the front and smaller at the rear. The four mounting surfaces 2a are parallel to the mounting mating surfaces 2000a of their respective windshields 2001, and all four mounting feet 2 can fit against the inner surface of the windshields 2001.

[0059] In other embodiments of the present invention, there may be two mounting legs 2, which are respectively placed on the left and right sides of the bracket body 1. The angles between the mounting surfaces 2a of the two mounting legs 2 and the horizontal plane may be the same or different. When there are two mounting legs 2, the dimensions of the mounting legs 2 in the front-rear direction can be increased to form a larger surface contact support at the mounting legs 2.

[0060] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the mounting leg 2 includes a connecting part 21 and a bending part 22. The connecting part 21 is connected to the bracket body 1 and extends in the vertical direction. The bending part 22 is connected to the top of the connecting part 21 and extends in a direction away from the bracket body 1. The upper surface of the bending part 22 defines the mounting surface 2a.

[0061] The connecting part 21 extends vertically, with its lower end connected to the main body 1 of the bracket and its upper end connected to the bent part 22. It is worth noting that the vertical direction of the connecting part 21 is a broad interpretation; it can extend vertically or at an angle relative to the vertical direction. The connecting part 21 is designed to support the bent part 22, allowing it to fit snugly against the inside of the windshield 2000, and to provide space between the main body 1 of the bracket and the windshield 2000 for the placement of components such as the lidar 200. Therefore, the extension direction and length of the connecting part 21 can be selected according to the interior layout of the vehicle.

[0062] The bent portion 22 is connected to the top of the connecting portion 21 and extends in a direction away from the bracket body 1. The connecting portion 21 and the bent portion 22 together form a bent structure. The upper surface of the bent portion 22 faces the windshield 2000, and the upper surface of the bent portion 22 defines the mounting surface 2a. The mounting surface 2a is directly formed by the upper surface of the bent portion 22, without the need to separately process an inclined mounting surface 2a on the mounting leg 2.

[0063] The mounting leg 2 can also have a transition structure at the connection between the connecting part 21 and the support body 1, such as a rounded corner or a thickened part at the junction of the connecting part 21 and the support body 1. The transition structure makes the material distribution at the connection between the mounting leg 2 and the support body 1 more reasonable, the load borne by the support body 1 is transmitted more smoothly at the mounting leg 2, and the stress concentration of the support body 1 at the mounting leg 2 is improved.

[0064] In some embodiments of the present invention, the connecting part 21 and the bending part 22 can be constructed as an integral structure, and the mounting leg 2 and the bracket body 1 can also be constructed as an integral structure. The mounting leg 2 does not need to be assembled with the bracket body 1 through additional connectors, thus reducing the number of parts and assembly steps. The simple structure of the mounting leg 2 helps to reduce the manufacturing and assembly difficulty of the lidar bracket 100.

[0065] In other embodiments of the present invention, the connecting portion 21 and the bending portion 22 can also be formed separately and then fixedly connected. For example, the top end of the connecting portion 21 and the bending portion 22 can be connected by welding, bonding or fasteners. When the connecting portion 21 and the bending portion 22 are separately provided, the mounting surface 2a of the bending portion 22 can be adjusted according to the actual tilt angle of the windshield 2001 during the assembly process, which is suitable for vehicle models where the tilt angle of the windshield 2001 varies.

[0066] In some embodiments of the present invention, such as Figure 5 As shown, a first connecting structure 23 is provided on the bent portion 22, which is used for positioning and connecting with the windshield 2001.

[0067] The first connecting structure 23 and the mounting surface 2a are located at the same part of the bending portion 22. The contact position and positioning position between the mounting leg 2 and the windshield 2001 are close to each other, which can improve assembly efficiency.

[0068] When assembling the lidar bracket 100 with the windshield 2001, the mounting leg 2 is first positioned and connected to the windshield 2001 through the first connecting structure 23, thus determining the position of the mounting leg 2 relative to the windshield 2001. Then, the mounting leg 2 is fixed to the windshield 2001, which can improve the reliability of the assembly.

[0069] In some embodiments of the present invention, such as Figure 5 As shown, the first connecting structure 23 includes a positioning boss 231 protruding from the mounting surface 2a, which is used for positioning and engaging with the windshield 2001. The first connecting structure 23 also includes a first connecting hole 232 formed on the mounting surface 2a, through which a first fastener passes to the first connecting hole 232 and a through hole on the windshield 2001 to fix the mounting leg 2 to the windshield 2001.

[0070] When assembling the lidar bracket 100 with the windshield 2001, the positioning boss 231 aligns and engages with the corresponding part on the windshield 2001. The position of the mounting leg 2 relative to the windshield 2001 within the mounting surface 2a is thus determined, allowing for rapid alignment of the mounting leg 2. For example, the windshield 2001 may have mounting holes corresponding to the positioning boss 231. The positioning boss 231 engages with the mounting holes, and the position of the mounting leg 2 relative to the windshield 2001 is determined by the engagement between the positioning boss 231 and the mounting holes.

[0071] Next, the first fastener passes through the first connecting hole 232 and the through hole on the windshield 2001 to fix the mounting leg 2 to the windshield 2001, thereby improving the connection stability between the mounting leg 2 and the windshield 2001.

[0072] When fixing, the positioning bosses 231 on the four mounting feet 2 can be positioned and engaged with the windshield 2001 respectively, and then the first fasteners at each mounting foot 2 can be tightened in sequence. Alternatively, the first fasteners can be tightened in a diagonal order so that the bracket body 1 gradually fits against the windshield 2001, and the bracket body 1 is less likely to deform due to local stress during the assembly process.

[0073] The positioning boss 231 and the first connecting hole 232 in the first connecting structure 23 are both provided on the mounting surface 2a. The positioning part and the fastening part between the mounting leg 2 and the windshield 2001 are both located on the mounting surface 2a. That is to say, the positioning reference, fitting reference and fastening point of the mounting leg 2 relative to the windshield 2001 are concentrated on the same surface.

[0074] In this way, the positioning, fitting and fastening of the mounting leg 2 are all completed at the mounting surface 2a. The mounting leg 2 is accurately positioned relative to the windshield 2001. The connection between the mounting leg 2 and the windshield 2001 is reliable and easy to disassemble, which helps to improve the assembly efficiency and maintenance convenience of the lidar bracket 100.

[0075] In some embodiments of the present invention, the angle between the mounting surface 2a and the horizontal plane is 10°-35°.

[0076] Mounting surface 2a is parallel to the corresponding mounting mating surface 2000a. The angle between mounting surface 2a and the horizontal plane is equal to the angle between mounting mating surface 2000a and the horizontal plane. The angle of mounting surface 2a matches the tilt angle of the inner side of the windshield 2001. The 10°-35° angle range covers the tilt angle range of the inner side of the windshield 2001 in common car models, ensuring that mounting surface 2a remains parallel and in close contact with the inner side of the windshield 2001.

[0077] Optionally, the angle between the mounting surface 2a and the horizontal plane can be 10°, 15°, 20°, 30° or 35°, etc.

[0078] The angle between the mounting surface 2a and the horizontal plane is determined when the mounting leg 2 is formed. The fitting angle between the mounting leg 2 and the inner side of the windshield 2001 is guaranteed during the forming stage. After the mounting leg 2 is installed on the windshield 2000, there is no need to adjust the mounting surface 2a. The assembly process of the lidar bracket 100 is reduced and the assembly efficiency is improved. At the same time, the consistency of the angle between the mounting surface 2a of each mounting leg 2 and the horizontal plane is good.

[0079] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the bracket body 1 has an installation area 1a, and the lidar 200 is installed in the installation area 1a. The installation area 1a is provided with a second connection structure 11, which is used to limit the lidar 200.

[0080] Mounting area 1a is the part on the bracket body 1 used to mount the lidar 200. The lidar 200 is mounted in mounting area 1a, with its bottom attached to and supported by the mounting area 1a. Mounting area 1a provides a mounting reference surface for the lidar 200.

[0081] The second connecting structure 11 is located in the installation area 1a and is used to limit the position of the lidar 200. After the lidar 200 is installed in the installation area 1a, the second connecting structure 11 constrains the lidar 200, restricting the position of the lidar 200 relative to the support body 1 in the left-right and front-back directions, thus determining the position of the lidar 200 within the installation area 1a.

[0082] It is worth noting that the installation area 1a is constructed as a plane, and the flatness of the installation area 1a can be determined according to the requirements of the lidar 200 for the installation reference surface. For example, the flatness of the installation area 1a is controlled within 1mm, and the installation area 1a can serve as the positioning reference surface of the lidar 200. The bottom of the lidar 200 fits well with the installation area 1a, which helps to improve the installation accuracy of the lidar 200.

[0083] In some embodiments of the present invention, such as Figure 4 , Figure 5 and Figure 6 As shown, the second connecting structure 11 includes a positioning pin 111, which is used for positioning and engaging with the lidar 200. The second connecting structure 11 also includes a second connecting hole 112, through which the second fastener 4 passes and connects to the lidar 200, thereby fixing the lidar 200 to the bracket body 1.

[0084] The positioning pin 111 extends upward from the mounting area 1a, and the bottom of the lidar 200 is provided with a positioning pin hole 201 corresponding to the positioning pin 111. During assembly, the positioning pin 111 first engages with the positioning pin hole 201 on the lidar 200, and the position of the lidar 200 relative to the bracket body 1 in the left-right and front-back directions is determined, thereby realizing the positioning of the lidar 200 within the mounting area 1a.

[0085] After positioning, the second fastener 4 passes through the second connecting hole 112 and connects to the threaded hole 202 on the lidar 200 and is tightened. For example, the second fastener 4 can be a Torx head bolt, the shank of which passes through the second connecting hole 112 and connects to the threaded hole 202 at the bottom of the lidar 200, thereby achieving a fixed connection between the lidar 200 and the bracket body 1.

[0086] The lidar 200 is positioned by the positioning pin 111 and then locked by the second fastener 4. The lidar 200 is positioned and then fixed relative to the bracket body 1, which improves assembly accuracy. The bottom of the lidar 200 fits into the installation area 1a, and a rigid connection is formed between the lidar 200 and the bracket body 1. The optical axis direction of the lidar 200 is determined relative to the vehicle coordinate system.

[0087] In some embodiments of the present invention, such as Figure 4 and Figure 6 As shown, there are two positioning pins 111, which are spaced apart in the left-right direction. There are four second connecting holes 112. The vertical projection shape of the mounting area 1a is rectangular, and the four second connecting holes 112 are respectively located at the corners of the mounting area 1a.

[0088] Two positioning pins 111 are spaced apart in the left-right direction, and each positioning pin 111 engages with two positioning pin holes 201 spaced apart in the left-right direction on the bottom of the lidar 200. The spaced positioning pins 111 restrict the movement of the lidar 200 relative to the support body 1 in both the left-right and front-back directions, and also restrict the rotation of the lidar 200 around the vertical direction, thereby stably confining the lidar 200 within the installation area 1a.

[0089] The vertical projection of the mounting area 1a is rectangular. Four second connecting holes 112 are respectively located at the four corners of the mounting area 1a, i.e., along the diagonal of the rectangle. Four second fasteners 4 apply a tightening force to the lidar 200 at the corners of the mounting area 1a. This ensures uniform force distribution on the bottom of the lidar 200, preventing localized warping and improving the installation stability of the lidar 200.

[0090] It is worth noting that the four second connecting holes 112 are arranged along the corners of the rectangular mounting area 1a. During assembly, the second fasteners 4 can be tightened in diagonal order, and the bottom of the lidar 200 gradually fits into the mounting area 1a, which helps to improve the fit between the lidar 200 and the bracket body 1.

[0091] In some specific embodiments of the present invention, the vertical projection shape of the mounting area 1a is rectangular, and two positioning pins 111 are respectively disposed at two opposite corners of the mounting area 1a.

[0092] The movement of the lidar 200 relative to the support body 1 in the left-right and front-back directions is restricted, and the rotation of the lidar 200 around the up-down direction is also restricted, thereby stably confining the lidar 200 within the installation area 1a.

[0093] In other embodiments of the present invention, there may be three or more positioning pins 111, and the multiple positioning pins 111 are arranged along the corners of the mounting area 1a.

[0094] In some embodiments of the present invention, such as Figure 5 As shown, the support body 1 has multiple heat dissipation holes 12, which penetrate the support body 1 in the vertical direction.

[0095] Multiple heat dissipation holes 12 penetrate the support body 1 in the vertical direction, forming multiple through channels inside the support body 1, thus increasing the contact area between the support body 1 and the air inside the cabin. At the same time, the heat dissipation holes 12 form channels for micro-air circulation on the support body 1, allowing air to flow within the heat dissipation holes 12.

[0096] The bottom of the lidar 200 contacts the mounting area 1a. The heat generated by the lidar 200 during operation is conducted through the metal shell at the bottom to the support body 1, and then dissipated into the surrounding air through the body of the support body 1 and the walls and edges of the heat dissipation holes 12. The heat generated by the lidar 200 during operation can be dissipated in a timely manner, which is conducive to the long-term stable operation of the lidar 200 inside the cabin.

[0097] Furthermore, the main body 1 of the bracket is connected to the windshield 2001 via the mounting feet 2, and some of the heat can be further conducted to the vehicle body through the windshield 2000, using the vehicle body as an auxiliary heat dissipation body.

[0098] By setting multiple heat dissipation holes 12 that run through the support body 1 in the vertical direction, heat dissipation function is achieved while removing some material from the support body 1, reducing the weight of the support body 1, thereby realizing the lightweight design of the lidar support 100, which is beneficial to saving manufacturing costs.

[0099] In some embodiments of the present invention, the heat dissipation holes 12 can be circular or square through holes, with a diameter of 4mm-8mm. Multiple heat dissipation holes 12 are arranged in an array around the periphery of the mounting area 1a and on the back of the bracket body 1. The diameter and spacing of the heat dissipation holes 12 can be determined based on the width of the bracket body 1. The positions of the heat dissipation holes 12 on the bracket body 1 avoid the mounting area 1a and the connection points between each mounting leg 2 and the bracket body 1.

[0100] In some embodiments of the present invention, heat dissipation ribs or thermal pads may also be provided on the support body 1 to further increase the contact area between the support body 1 and the air.

[0101] In some embodiments of the present invention, a thermally conductive interface material may be coated between the support body 1 and the bottom of the lidar 200 to reduce the contact thermal resistance between the two.

[0102] In this way, multiple heat dissipation paths work simultaneously, and the heat generated by the lidar 200 can be transferred in a timely manner, keeping the operating temperature of the lidar 200 within the cabin within a reasonable range.

[0103] In some embodiments of the present invention, the lidar bracket 100 is a metal part; and / or, the lidar bracket 100 is a one-piece molded part.

[0104] The lidar bracket 100 is made of metal, which has better thermal conductivity than plastic. The heat generated by the lidar 200 during operation can be quickly conducted to all parts of the bracket body 1 and dissipated into the surrounding air. Compared to plastic parts, metal parts do not require additional thermal interface material coating or heat dissipation fins to conduct heat. The lidar bracket 100 has fewer parts and fewer assembly steps.

[0105] The lidar bracket 100 is a one-piece molded part. The bracket body 1, the mounting legs 2, the mounting area 1a, and the various connecting structures can be molded in one piece. There is no need to assemble the parts with connectors, which can improve assembly efficiency. In addition, the lidar bracket 100 has good overall integrity, which can improve structural stability.

[0106] In some embodiments of the present invention, the lidar bracket 100 can be integrally formed from ADC12 aluminum alloy using a die-casting process. ADC12 aluminum alloy has a thermal conductivity of approximately 96 W / (m·K), a tensile strength of approximately 228 MPa, a yield strength of approximately 154 MPa, and a density of approximately 2.7 g / cm³, thus balancing structural strength, thermal conductivity, and lightweight requirements, while also being low in cost and suitable for mass production.

[0107] In other embodiments of the present invention, the lidar bracket 100 may also be made of other die-cast aluminum alloys, such as A380 aluminum alloy or AlSi10MnMg aluminum alloy, with a thermal conductivity of about 90W / (m·K) to 100W / (m·K), which also have good die-casting formability; among them, the tensile strength of A380 aluminum alloy is slightly higher than that of ADC12, which is suitable for vehicles with high strength requirements, while AlSi10MnMg aluminum alloy has better ductility and is suitable for scenarios that require a certain degree of plastic deformation.

[0108] In other embodiments of the present invention, the lidar bracket 100 may also be made of magnesium alloy, such as AZ91D magnesium alloy or AM60B magnesium alloy. Magnesium alloy has a density of approximately 1.8 g / cm³, is about 30% lighter than aluminum alloy, has higher specific stiffness, and a thermal conductivity of approximately 50 W / (m·K) to 70 W / (m·K). Using magnesium alloy can further reduce the weight of the lidar bracket 100 while maintaining structural rigidity. For example, compared to using ADC12 aluminum alloy, it can reduce weight by 20% to 25%, making it suitable for vehicle models where weight is a significant concern.

[0109] In some embodiments of the present invention, the support body 1 has multiple weight-reducing holes in non-critical load-bearing areas. The weight-reducing holes are elliptical or square through holes, and the multiple weight-reducing holes are arranged in an array on the support body 1. For example, the major axis of the elliptical weight-reducing hole is 15mm-25mm and the minor axis is 8mm-12mm, and the side length of the square weight-reducing hole is 16mm-20mm.

[0110] The weight-reducing holes are located in non-critical load-bearing areas of the support body 1. Material is retained in the load-bearing sections of the support body 1, while material is removed from the sections primarily used for connection and sealing. The weight-reducing holes are arranged in an array, ensuring the support body 1 maintains a complete load-bearing path even after the holes are created.

[0111] In this way, the weight of the main support body 1 is reduced while ensuring structural strength, and the load on the windshield 2001 and the windshield system is reduced.

[0112] In some embodiments of the present invention, the support body 1 is provided with a plurality of reinforcing ribs, the height of which is 3mm-5mm and the thickness is 1mm-1.5mm. The reinforcing ribs are placed on the parts of the support body 1 where the rigidity needs to be improved. Through the cooperation of the weight-reducing holes and the reinforcing ribs, the support body 1 maintains structural rigidity while removing redundant material.

[0113] For example, the weight of the bracket body 1 is reduced by about 10% compared to the structure without weight reduction holes; the first natural frequency of the bracket body 1 is not lower than 48Hz, which is higher than the low frequency vibration frequency commonly encountered during vehicle operation, so the bracket body 1 is less likely to experience low frequency resonance during vehicle operation; under a static load of 1g, the maximum deformation of the installation area 1a is less than 0.10mm, which meets the installation stiffness requirements of the lidar 200.

[0114] In this way, the lidar bracket 100 maintains structural rigidity and modal characteristics while being lightweight, which helps to ensure the stability of the lidar 200's installation posture during vehicle movement.

[0115] In some embodiments of the present invention, such as Figure 2 , Figure 8 and Figure 10 As shown, the lidar bracket 100 also includes a mounting structure 3. At least one of the upper surface, the rear end face, and the lower surface of the bracket body 1 is provided with the mounting structure 3. The mounting structure 3 is used to connect with the camera 300, the rearview mirror 500, or the overhead light 400.

[0116] The support body 1 extends along the front-to-back and left-to-right directions. The upper, rear, and lower surfaces of the support body 1 face different directions, providing installation positions for different parts. The lidar support 100 can be equipped with mounting structures 3 at one or more locations on the upper, rear, and lower surfaces of the support body 1, depending on the arrangement of the parts inside the cabin.

[0117] The camera 300, dome light 400, and interior rearview mirror 500 all use the bracket body 1 as their mounting carrier. The relative positions of each component are determined by the bracket body 1, eliminating the need for separate mounting points on the windshield 2000 or the vehicle body. During assembly, simply install the bracket body 1 onto the windshield 2000, and then assemble each component sequentially, reducing the overall vehicle assembly process. The compact arrangement of components in the front area of ​​the cabin facilitates a compact and concealed layout of these components, further reducing the complexity of the overall vehicle assembly.

[0118] In some embodiments of the present invention, such as Figure 1 and Figure 8 As shown, the mounting structure 3 includes a mounting cover 31 disposed at the front end of the upper surface of the bracket body 1. The mounting cover 31 defines a mounting groove 311 that opens to the front, and the camera 300 is mounted in the mounting groove 311.

[0119] Mounting cover 31 is located on the front right side of the upper surface of the bracket body 1. Mounting cover 31 protrudes upward from the bracket body 1 and defines a mounting groove 311, which opens forward. Camera 300 is inserted into the mounting groove 311 from the front, with the lens of camera 300 facing forward to collect image information of the road in front of the vehicle.

[0120] The contour of the mounting slot 311 is adapted to the shape of the camera 300. After the camera 300 is installed in the mounting slot 311, the center of the lens of the camera 300 and the field of view of the lidar 200 do not interfere with each other, that is, the center of the lens does not fall within the field of view of the lidar 200. For example, the optical axis of the camera 300 is parallel to the detection optical axis of the lidar 200, and their field of view does not overlap in the horizontal and vertical directions, so they are not likely to interfere with each other.

[0121] In some embodiments of the present invention, such as Figure 7 and Figure 9 As shown, the installation structure 3 includes a snap-fit ​​platform 32 located at the rear end of the bracket body 1. The ceiling light 400 is installed from top to bottom, and the ceiling light 400 is connected and fixed to the bracket body 1.

[0122] In some embodiments of the present invention, such as Figure 10 , Figure 11 and Figure 12 As shown, the mounting structure 3 includes a mounting base 33 disposed on the lower surface of the bracket body 1, the mounting base 33 having a sliding groove 331 extending in the left-right direction; and a slot 34 disposed on the lower surface of the bracket body 1.

[0123] The interior rearview mirror 500 includes a mirror body 510 and a mounting top 520. The mounting top 520 is located at the top of the mirror body 510. During assembly, the mounting top 520 is inserted into the slide groove 331 from the left and right directions. After the mounting top 520 slides into place in the slide groove 331, the interior rearview mirror 500 is suspended below the bracket body 1.

[0124] The rearview mirror 500 also includes a cover 530, which surrounds the mirror body 510. The upper surface of the cover 530 is provided with multiple elastic claws 531, which engage with slots 34 respectively. The cover 530 is fixed to the bracket body 1. The multiple elastic claws 531 engaging with the slots 34 increase the number of connection points between the cover 530 and the bracket body 1, reducing vibration and noise during vehicle operation. Furthermore, the snap-fit ​​connection method facilitates the assembly and disassembly of the cover 530, promoting rapid assembly and subsequent maintenance and replacement.

[0125] The structure and operation of a lidar bracket 100 according to a specific embodiment of the present invention are described below with reference to the accompanying drawings.

[0126] like Figure 1 and Figure 2As shown, the lidar bracket 100 is installed on the inner side of the vehicle's windshield 2001. The lidar bracket 100 includes a bracket body 1 and four mounting feet 2. The bracket body 1 has a plate-like structure, and its upper surface is used to mount the lidar 200. The central area of ​​the bracket body 1 is constructed as a mounting area 1a, which is provided with two positioning pins 111 and four second connecting holes 112. The two positioning pins 111 are spaced apart in the left-right direction. The vertical projection of the mounting area 1a is rectangular, and the four second connecting holes 112 are respectively located at the corners of the mounting area 1a. The four mounting feet 2 are located on the left and right sides of the bracket body 1, with two mounting feet 2 on each side. The mounting feet 2 on the same side are spaced apart in the front-back direction. The mounting leg 2 includes a connecting part 21 and a bending part 22. The connecting part 21 is connected to the bracket body 1 and extends in the vertical direction. The bending part 22 is connected to the top of the connecting part 21 and extends in a direction away from the bracket body 1. The upper surface of the bending part 22 defines a mounting surface 2a. A first connecting structure 23 is provided on the bending part 22. The first connecting structure 23 includes a positioning boss 231 and a first connecting hole 232. The bracket body 1 has a plurality of heat dissipation holes 12 that penetrate the bracket body 1 in the vertical direction. A mounting cover 31 is provided at the front end of the upper surface of the bracket body 1. The mounting cover 31 defines a mounting groove 311 that opens forward. A snap-fit ​​platform 32 is provided at the rear end of the bracket body 1. The snap-fit ​​platform 32 defines a snap-fit ​​groove that opens upward. A mounting seat 33 is provided on the lower surface of the bracket body 1. A sliding groove 331 extending in the left-right direction is provided on the mounting seat 33. A slot 34 is also formed on the lower surface of the bracket body 1.

[0127] During assembly, the lidar 200 is first placed in the mounting area 1a of the bracket body 1, so that the positioning pin hole 201 on the lidar 200 engages with the two positioning pins 111 to position the lidar 200 within the mounting area 1a. Then, the second fastener 4 passes through the four second connecting holes 112 and connects to the lidar 200, fixing the lidar 200 to the bracket body 1. Next, the lidar bracket 100 is inserted into the compartment, so that the mounting surfaces 2a of the four mounting legs 2 correspond to the mounting mating surfaces 2000a on the inner side of the windshield 2001. After the positioning boss 231 is positioned and engaged with the windshield 2001, the first fastener is passed through the first connecting hole 232 and the through hole on the windshield 2000 in sequence and tightened. The lidar bracket 100 is fixed to the inner side of the windshield 2001, and the lidar 200 extends horizontally along the bracket body 1. Subsequently, the camera 300 is installed into the mounting slot 311 of the mounting cover 31 and fixed at the camera mounting hole; the mounting top 520 of the interior rearview mirror 500 is installed into the sliding groove 331 of the mounting base 33 from the left and right directions; the elastic claw 531 of the protective cover 530 is engaged with the slot 34 on the lower surface of the bracket body 1; and the locking block 401 of the top light 400 is inserted from top to bottom into the locking slot of the locking platform 32.

[0128] During operation, the lidar 200 emits and receives laser pulses to detect road information in front of the vehicle; the camera 300 collects image information in front of the vehicle, and the data from both are fused and transmitted to the vehicle's controller. During vehicle movement, the support body 1 bears vibration loads. The positioning pin 111, the second connecting hole 112, and the mounting feet 2 on the support body 1 work together to maintain a fixed attitude of the lidar 200 relative to the vehicle coordinate system, ensuring the stability of the lidar 200's optical axis. Simultaneously, the heat generated by the lidar 200 is conducted through the support body 1 and dissipated into the cabin air through the heat dissipation holes 12, which is beneficial for the lidar 200's stable operation over long periods.

[0129] According to a second aspect of the present invention, a lidar assembly 1000 includes a lidar 200 and a lidar bracket 100 according to a first aspect of the present invention, wherein the lidar 200 is mounted on the bracket body 1.

[0130] The lidar assembly 1000 is a component mounted on a vehicle for detecting target information in front of the vehicle. It includes a lidar 200 and a lidar bracket 100 for mounting the lidar 200 onto the vehicle. The lidar 200 emits and receives laser pulses to detect target information on the road ahead of the vehicle. The detection performance of the lidar 200 is related to its mounting orientation on the vehicle; the optical axis direction of the lidar 200 needs to be determined relative to the vehicle's coordinate system.

[0131] The lidar 200 is mounted on the upper surface of the bracket body 1, and the lidar bracket 100 is mounted inside the windshield 2000 of the vehicle. The lidar 200 is mounted to the bracket body 1 via the second connecting structure 11 at the mounting area 1a. The bracket body 1 extends horizontally, and the optical axis direction of the lidar 200 is determined relative to the vehicle coordinate system.

[0132] The lidar 200 can be a forward-looking medium-long-range lidar. The forward-looking medium-long-range lidar is arranged inside the vehicle cabin, located on the inside of the windshield 2001. The road information detected by the lidar 200 and the image information collected by the camera 300 can be fused and transmitted to the vehicle controller to provide a basis for the vehicle's driving assistance functions.

[0133] According to the embodiment of the present invention, the lidar assembly 1000, by adopting the lidar bracket 100 described above, determines the optical axis direction of the lidar 200 relative to the vehicle coordinate system, which is beneficial for the lidar 200 to meet the design requirements in terms of detection field of view and can improve detection accuracy.

[0134] In some embodiments of the present invention, such as Figure 1 and Figure 8 As shown, the lidar assembly 1000 also includes a camera 300. A mounting cover 31 is provided at the front end of the upper surface of the bracket body 1. The mounting cover 31 defines a mounting groove 311 that opens to the front. The camera 300 is installed in the mounting groove 311.

[0135] Mounting cover 31 is located on the front right side of the upper surface of the bracket body 1. Mounting cover 31 protrudes upward from the bracket body 1 and defines a mounting groove 311, which opens forward. Camera 300 is inserted into the mounting groove 311 from the front, with the lens of camera 300 facing forward to collect image information of the road in front of the vehicle.

[0136] The contour of the mounting slot 311 is adapted to the shape of the camera 300. After the camera 300 is installed in the mounting slot 311, the center of the lens of the camera 300 and the field of view of the lidar 200 do not interfere with each other. For example, the optical axis of the camera 300 is parallel to the detection optical axis of the lidar 200, and their field of view does not overlap in the horizontal and vertical directions, so they are not likely to interfere with each other.

[0137] It is worth noting that the walls of the mounting slot 311 surround the camera 300, blocking sunlight, headlights, and other light rays directed at the camera 300, thus reducing the impact of stray light on the image captured by the camera 300. Furthermore, the mounting cover 31 and the camera 300 are centrally located at the front end of the support body 1, reducing the space occupied by the front components inside the cabin.

[0138] In some embodiments of the present invention, the depth of the mounting groove 311 is 15mm-25mm, and a camera mounting hole is provided at the bottom of the mounting groove 311. The camera 300 is fixed to the camera mounting hole by fasteners, and the assembly and disassembly of the camera 300 are relatively convenient.

[0139] In this way, the camera 300 and the lidar 200 are jointly arranged on the support body 1, and their detection fields of view do not interfere with each other, reducing the number of mounting structures 3 for the front parts inside the cabin.

[0140] In some embodiments of the present invention, such as Figure 2 and Figure 9 As shown, the lidar assembly 1000 also includes a top light 400. The rear end of the bracket body 1 is provided with a snap-fit ​​platform 32, which defines a snap-fit ​​groove that opens upwards. The top light 400 has a snap-fit ​​block 401, which is inserted into the snap-fit ​​groove.

[0141] The snap-fit ​​platform 32 is located at the rear end of the bracket body 1, with the snap-fit ​​groove facing upwards. The ceiling light 400 is installed from top to bottom, and the snap-fit ​​block 401 of the ceiling light 400 is inserted into the snap-fit ​​groove. The ceiling light 400 and the bracket body 1 are snap-fitted and fixed together by the snap-fit ​​block 401 and the snap-fit ​​groove.

[0142] It is worth noting that multiple snap-fit ​​platforms 32 can be set. For example, two snap-fit ​​platforms 32 are set at the rear end of the bracket body 1. The ceiling light 400 is snapped into multiple snap-fit ​​slots through multiple snap-fit ​​blocks 401, making the connection between the ceiling light 400 and the bracket body 1 more stable.

[0143] In this way, the dome light 400 is connected to the bracket body 1 via a snap-fit ​​connection. This snap-fit ​​connection facilitates the assembly and disassembly of the dome light 400, improving assembly efficiency. Furthermore, the dome light 400 does not require a separate mounting point on the vehicle body or roof, simplifying the structure.

[0144] In some embodiments of the present invention, such as Figure 10 and Figure 11 As shown, the lidar assembly 1000 also includes an interior rearview mirror 500. The interior rearview mirror 500 includes a mirror body 510 and a mounting top 520. The mounting top 520 is located at the top of the mirror body 510. A mounting seat 33 is provided on the lower surface of the bracket body 1. The mounting seat 33 has a sliding groove 331 extending in the left and right direction. The mounting top 520 is installed in the sliding groove 331.

[0145] Mounting base 33 is disposed on the lower surface of bracket body 1, and a sliding groove 331 extending in the left-right direction is provided on mounting base 33. Mounting top 520 of interior rearview mirror 500 is located at the top of mirror body 510. During assembly, mounting top 520 is inserted into sliding groove 331 from the left-right direction. After mounting top 520 slides into the sliding groove 331, interior rearview mirror 500 is suspended below bracket body 1.

[0146] The rearview mirror 500 is located below the bracket body 1, with the mirror body 510 facing inwards, allowing the driver to observe the situation behind the vehicle. The rearview mirror 500 is mounted via the bracket body 1, and the relative positions of the rearview mirror 500, the lidar 200, and the camera 300 are determined by the bracket body 1, eliminating the need to adjust the relative positions of each component individually during assembly.

[0147] The mounting bracket 520 and the sliding groove 331 are connected by a sliding fit. During assembly, the interior rearview mirror 500 slides into the sliding groove 331 to complete the positioning. After installation, the position of the interior rearview mirror 500 relative to the bracket body 1 is determined by the extension direction of the sliding groove 331, making it less likely for the interior rearview mirror 500 to wobble relative to the bracket body 1. The assembly operation of the interior rearview mirror 500 is simple, which helps to improve assembly efficiency.

[0148] In some embodiments of the present invention, such as Figure 10 and Figure 12 As shown, the interior rearview mirror 500 also includes a protective cover 530, which surrounds the mirror body 510. The upper surface of the protective cover 530 is provided with a plurality of elastic claws 531, and the lower surface of the bracket body 1 is formed with a slot 34, and the elastic claws 531 engage with the slot 34.

[0149] The protective cover 530 surrounds the outer periphery of the mirror body 510, providing shielding and protection for the mirror body 510, while also making the appearance of the rearview mirror 500 neater. The upper surface of the protective cover 530 is provided with multiple elastic claws 531 that extend upwards. The lower surface of the bracket body 1 forms a groove 34, and the multiple elastic claws 531 engage with the groove 34 respectively, thus fixing the protective cover 530 to the bracket body 1.

[0150] Multiple elastic claws 531 engage with the slot 34, increasing the number of connection points between the cover 530 and the bracket body 1, making the cover 530 less prone to vibration and noise during vehicle operation. Furthermore, the snap-fit ​​connection method facilitates the assembly and disassembly of the cover 530, enabling rapid assembly and subsequent maintenance and replacement.

[0151] By using the bracket body 1 as the mounting carrier for the camera 300, dome light 400, and interior rearview mirror 500, the relative positions of each component are determined by the bracket body 1.
