DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0040] Reference will be made below to Figure 1 - Figure 2 describe a radar mounting assembly 100 according to an embodiment of the present utility model.

[0041] The radar mounting assembly 100 according to an embodiment of the first aspect of the present utility model includes: a mounting bracket 10, a radar device 20, and a fastener 30.

[0042] The radar device 20 has a mounting lug 21, and the mounting lug 21 has a mounting hole 22. For example, the radar device 20 includes four mounting lugs 21, and the four mounting lugs 21 are distributed at four corners of the radar device 20, and each mounting lug 21 has a mounting hole 22, so that the radar device 20 is fixed more firmly.

[0043] The fastener 30 is used to install and fix the radar device 20 on the mounting bracket 10. The fastener 30 includes a bolt 31, a locking nut 34, and a vibration-damping pad 35. The bolt 31 includes a first rod segment 32 and a second rod segment 33 arranged along the length direction of the bolt 31. The vibration-damping pad 35 is formed in an annular shape and is sleeved on the outer peripheral side of the first rod segment 32 and together with the first rod segment 32, it forms a connecting portion 36. The outer peripheral wall of the second rod segment 33 is formed with a threaded structure. By making the fastener 30 include the vibration-damping pad 35, the vibration-damping pad 35 can be used as a buffer to play a role in vibration isolation, thereby preventing the vibration of the vehicle body from being transmitted to the laser radar through the fastening system, resulting in a reduction in the accuracy of the laser radar; at the same time, it can also prevent the vibration of the internal motor of the laser radar from being transmitted to the vehicle body through the fastening system and being conducted into the passenger compartment, affecting the customer experience, and reducing the impact on NVH performance.

[0044] By making the bolt 31 include the first rod segment 32, the vibration-damping pad 35 is formed into a ring shape and is sleeved on the outer peripheral side of the first rod segment 32 and together with the first rod segment 32 constitutes a connecting portion 36, so that when the assembler installs and fixes the radar device 20 on the mounting bracket 10, the vibration-damping pad 35 and the bolt 31 can be formed into a whole, and the whole can be connected to the radar device 20 and the mounting bracket 10, so that the radar device 20 is fixed on the mounting bracket 10, the installation operation steps are simplified, the assembly man-hours are reduced, and the assembly efficiency is improved.

[0045] The connecting portion 36 is connected to the mounting bracket 10 and at least part of the vibration-damping pad 35 is located between the first rod segment 32 and the mounting bracket 10. The second rod segment 33 is inserted into the mounting hole 22. The locking nut 34 is threadedly connected to the second rod segment 33 and is located on the side of the mounting lug 21 away from the vibration-damping pad 35. By making the bolt 31 include the second rod segment 33, the outer peripheral wall of the second rod segment 33 is formed with a threaded structure, and the locking nut 34 is threadedly connected to the second rod segment 33 and is located on the side of the mounting lug 21 away from the vibration-damping pad 35, the connection between the bolt 31 and the nut can be tightened, and the vibration-damping pad 35 and the mounting lug 21 can be fixed relative to the bolt 31 by the locking nut 34, so that the radar device 20 is installed and fixed more firmly.

[0046] According to the radar mounting assembly 100 of the embodiments of the present utility model, it includes a mounting bracket 10, a radar device 20 and a fastener 30. By making the fastener 30 include a bolt 31, a lock nut 34 and a vibration damping pad 35, and sleeving the vibration damping pad 35 on the bolt 31, during the process of installing and fixing the radar mounting assembly 100 by the assembler, the vibration damping pad 35 and the bolt 31 can be formed into an integral body, and this integral body is connected to the radar device 20 and the mounting bracket 10, so that the radar device 20 is fixed on the mounting bracket 10, simplifying the operation steps of installation, reducing the assembly man-hours, and thus improving the assembly efficiency.

[0047] According to some embodiments of the present utility model, referring to Figure 2 , the fastener 30 further includes a metal bushing 37. The metal bushing 37 is sleeved on the outer peripheral side of the first rod section 32, and the vibration damping pad 35 is sleeved on the outer peripheral side of the metal bushing 37. By arranging the metal bushing 37 on the outer peripheral side of the first rod section 32 and sleeving the vibration damping pad 35 on the outer peripheral side of the metal bushing 37, the metal bushing 37 can cooperate with other components of the bolt 31. The metal bushing 37 has a relatively large stiffness and is not easily deformed, which can avoid the reduction of installation accuracy due to the aging and deformation of the damping pad; moreover, the elasticity of the metal bushing 37 is smaller than that of the vibration damping pad 35, which can avoid problems such as connection failure caused by the attenuation of the fastening torque and loosening after fastening.

[0048] According to some embodiments of the present utility model, referring to Figure 2 , the first rod section 32 and the metal bushing 37 are in interference fit. By making the first rod section 32 and the metal bushing 37 in interference fit, the connection between the metal bushing 37 and the bolt 31 can be made more firm, avoiding the circumferential rotation of the metal bushing 37 relative to the bolt 31 along the circumference of the bolt 31 or the axial movement along the axis of the bolt 31.

[0049] According to some embodiments of the present utility model, referring to Figure 2 , a convex structure 38 is formed on the outer peripheral wall of the first rod section 32, and the convex structure 38 abuts against the metal bushing 37. For example, a convex structure 38 is formed on the outer peripheral wall of the first rod section 32. The convex structure 38 may include a plurality of ribs, the ribs may extend along the axial direction of the first rod section 32, and the plurality of ribs may be arranged at intervals along the circumferential direction of the first rod section 32. By arranging the convex structure 38 on the outer peripheral wall of the first rod section 32 and making the convex structure 38 abut against the metal bushing 37, the fixation of the metal bushing 37 relative to the bolt 31 can be made more reliable, avoiding the circumferential rotation of the metal bushing 37 relative to the bolt 31 along the circumference of the bolt 31 or the axial movement along the axis of the bolt 31; moreover, during assembly, the bolt 31, the vibration damping pad 35 and the metal bushing 37 can be formed into an integral body, and this integral body is assembled onto the metal bracket of the lidar, and then the lock nut 34 is tightened. When tightening the nut, only one hand operation is required, reducing the assembly man-hours and improving the assembly efficiency.

[0050] According to some embodiments of the present invention, referring to Figure 2 , the interference fit amount between the first rod segment 32 and the metal bushing 37 is E, and the value range of E is 0.1 mm - 0.3 mm. For example, the value of E can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, etc. By making the interference fit amount E between the first rod segment 32 and the metal bushing 37 not less than 0.1 mm, the fixing of the metal bushing 37 relative to the bolt 31 can be made more reliable; by making the interference fit amount E between the first rod segment 32 and the metal bushing 37 not greater than 0.3 mm, the metal bushing 37 can be more easily installed on the first rod segment 32.

[0051] According to some embodiments of the present invention, referring to Figure 2 , the metal bushing 37 is in interference fit with the damping pad 35. By making the metal bushing 37 in interference fit with the damping pad 35, the connection between the metal bushing 37 and the damping pad 35 can be made tighter, preventing the damping pad 35 from falling off the metal bushing 37.

[0052] According to some embodiments of the present invention, referring to Figure 2 , the metal bushing 37 includes a bushing body 39 and a bushing flange 40. The bushing body 39 is annular and sleeved on the outer peripheral side of the first rod segment 32. The bushing flange 40 is connected to one side of the bushing body 39 close to the mounting lug 21, and the bushing flange 40 abuts against the mounting lug 21 in the length direction of the bolt 31. By making the metal bushing 37 include the bushing body 39, and the bushing body 39 is annular and sleeved on the outer peripheral side of the first rod segment 32, the connection area between the metal bushing 37 and the bolt 31 can be increased, making the connection between the metal bushing 37 and the bolt 31 tighter; by making the metal bushing 37 include the bushing flange 40, and making the bushing flange 40 connected to one side of the bushing body 39 close to the mounting lug 21, and the bushing flange 40 abuts against the mounting lug 21 in the length direction of the bolt 31, the connection area between the bushing flange 40 and the mounting lug 21 can be increased, increasing the stability and reliability of the connection between the metal bushing 37 and the mounting lug 21.

[0053] According to some embodiments of the present invention, referring to Figure 2 , the bolt 31 includes a bolt head 41. One side of the bolt head 41 adjacent to the damping pad 35 has a first flange surface 42. The damping pad 35 is located between the first flange surface 42 and the bushing flange 40 and abuts against the first flange surface 42 and the bushing flange 40. By making the damping pad 35 abut against the first flange surface 42 and the bushing flange 40, the damping pad 35 can be fixed relative to the bolt 31 in the axial direction of the bolt 31, preventing the damping pad 35 from moving.

[0054] According to some embodiments of the present utility model, referring to Figure 2 , in the length direction of the bolt 31, the bushing body 39 is spaced apart from the first flange surface 42. By spacing apart the bushing body 39 from the first flange surface 42, a certain amount of compression can be reserved for the vibration damping pad 35. When the vibration damping pad 35 is subjected to vibration, there is sufficient space for compression or extension, thereby achieving the effect of vibration damping.

[0055] According to some embodiments of the present utility model, referring to Figure 2 , in the length direction of the bolt 31, the end surface of the bushing body 39 facing the first flange surface 42 is the bushing end surface 43, and the distance between the bushing end surface 43 and the first flange surface 42 is A. The range of A is 0.5 mm - 1 mm. For example, the value of A can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc. By making the distance A between the bushing end surface 43 and the first flange surface 42 not less than 0.5 mm, the reserved compression amount for the vibration damping pad 35 can be sufficient, so that the vibration damping pad 35 can fully achieve the vibration damping effect; by making the distance A between the bushing end surface 43 and the first flange surface 42 not greater than 1 mm, the overall length of the bolt 31 can be prevented from being too long and occupying space.

[0056] According to some embodiments of the present utility model, referring to Figure 2 , the second rod segment 33 is in clearance fit with the mounting hole 22, and the clearance amount between the second rod segment 33 and the mounting hole 22 is C. The value range of C is 1 mm - 2 mm. For example, the value of C can be 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2 mm, etc. By making the value of the clearance amount C between the second rod segment 33 and the mounting hole 22 not less than 1 mm, the radar device 20 and the second rod segment 33 can be more easily assembled; by making the value of the clearance amount C between the second rod segment 33 and the mounting hole 22 not greater than 2 mm, the fastener 30 can be effectively limited, and the fit between the fastener 30 and the mounting lug 21 is more stable, avoiding excessive clearance between the fastener 30 and the mounting lug 21 and causing the fastener 30 to easily sway significantly relative to the mounting lug 21.

[0057] According to some embodiments of the present utility model, referring to Figure 2, in the length direction of the bolt 31, the part of the bolt 31 located away from the mounting lug 21 of the locking nut 34 is the exposed section 44, and the length of the exposed section 44 is D, and D is greater than twice the pitch of the thread structure. The exposed section 44 can leave a certain allowance for the locking nut 34 to move away from the mounting lug 21, so that the locking nut 34 can still be located on the bolt 31 after loosening, thereby preventing the locking nut 34 from falling off the bolt 31 after loosening and causing connection failure. By making the length D of the exposed section 44 greater than twice the pitch of the thread structure, the allowance for the locking nut 34 to move away from the mounting lug 21 can be made more sufficient, thereby more effectively preventing the locking nut 34 from falling off.

[0058] According to some embodiments of the present invention, referring to Figure 2 , a second flange surface 45 is formed on the side of the locking nut 34 close to the mounting lug 21, and the second flange surface 45 abuts against the mounting lug 21. By making the second flange surface 45 abut against the mounting lug 21, the locking nut 34 and the mounting lug 21 can be relatively fixed in the axial direction of the bolt 31, preventing the mounting lug 21 from moving axially relative to the bolt 31.

[0059] According to some embodiments of the present invention, referring to Figure 2 , a chamfered inclined surface 46 is formed at one end of the locking nut 34 away from the mounting lug 21. The chamfered inclined surface 46 extends obliquely in the direction towards the central axis of the adjacent bolt 31 in the direction from the first rod section 32 to the second rod section 33. A plurality of locking points are arranged at intervals along the circumferential direction of the locking nut 34 on the chamfered inclined surface 46, and depressions are formed at the locking points towards the central axis direction of the second rod section 33, so as to form locking protrusions protruding towards the central axis direction close to the locking nut 34 on the inner circumferential surface of the locking nut 34. By forming locking protrusions protruding towards the central axis direction close to the locking nut 34 on the inner circumferential surface of the locking nut 34, the connection at the fastening point with the second rod section 33 can be made more firm, so that the locking nut 34 is difficult to move relative to the second rod section 33, making the locking nut 34 more fixed relative to the bolt 31 and reducing the risk of loosening or falling off of the locking nut 34.

[0060] For example, the method of setting the locking points and fastening points on the locking nut 34 includes: using a machine to press the locking points radially inwards on the chamfered inclined surface 46 of the locking nut 34, and then forming fastening points on the inner thread surface of the locking nut 34.

[0061] According to some embodiments of the present invention, the damping pad 35 is a rubber part. By making the damping pad 35 a rubber part, the damping pad 35 can not only meet the connection and support of the mounting bracket 10, but also have sufficient elasticity to reduce vibration and improve the NVH performance of the vehicle.

[0062] According to some embodiments of the present utility model, the hardness of the vibration damping pad 35 is HA30 - HA40. For example, the hardness of the vibration damping pad 35 can be HA30, HA32, HA34, HA36, HA38, HA40, etc. By comparing the vibration attenuation and isolation effects of rubber vibration damping pads under different hardnesses and selecting the most suitable hardness requirements, by making the hardness of the vibration damping pad 35 be HA30 - HA40, the vibration damping pad 35 can not only meet the connection and support of the mounting bracket 10, but also have sufficient elasticity to slow down vibration, with the vibration isolation rate being greater than 15 dB, improving the NVH performance of the vehicle; and it can also pass fatigue and reliability tests such as vehicle durability, meeting the design requirements.

[0063] According to some embodiments of the present utility model, referring to Figure 1 and Figure 2 , a first card slot 11 is provided on the mounting bracket 10, and at least a part of the connecting portion 36 is snapped into the first card slot 11. By providing the first card slot 11 on the mounting bracket 10 and snapping at least a part of the connecting portion 36 into the first card slot 11, the connection between the mounting bracket 10 and the connecting portion 36 can be made more firm, preventing the mounting bracket 10 from moving radially along the bolt 31 relative to the connecting portion 36, resulting in a reduction in the installation accuracy. For example, the first card slot 11 is U-shaped, and the connecting portion 36 can be snapped into the first card slot 11 from the opening of the first card slot 11.

[0064] According to some embodiments of the present utility model, referring to Figure 2 , a second card slot 47 is formed on the outer peripheral wall of the vibration damping pad 35, and the mounting bracket 10 includes a clamping plate 12 that surrounds the outer peripheral side of the mounting hole 22, and the clamping plate 12 is snapped into the second card slot 47. By forming the second card slot 47 on the outer peripheral wall of the vibration damping pad 35 and snapping the clamping plate 12 into the second card slot 47, the connection between the mounting bracket 10 and the vibration damping pad 35 can be made more firm, preventing the mounting bracket 10 from moving axially along the bolt 31 relative to the vibration damping pad 35, resulting in a reduction in the installation accuracy. For example, the vibration damping pad 35 is in an I-shape, and the second card slot 47 is formed on the outer peripheral wall of the vibration damping pad 35.

[0065] According to some embodiments of the present utility model, referring to Figure 2 , the clamping plate 12 and the second card slot 47 are in an interference fit. By making the clamping plate 12 and the second card slot 47 in an interference fit, the connection between the clamping plate 12 and the second card slot 47 can be made more firm, more fully preventing the clamping plate 12 from moving or falling off, resulting in a reduction in the installation accuracy.

[0066] Among them, the interference fit amount between the clamping plate 12 and the second card slot 47 is B, and the value range of B is 0.3 mm - 0.5 mm. For example, the value of B can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc. By making the interference fit amount B between the clamping plate 12 and the second card slot 47 not less than 0.3 mm, the connection between the clamping plate 12 and the second card slot 47 can be made more firm, and the movement or detachment of the clamping plate 12 can be more effectively prevented; by making the interference fit amount B between the clamping plate 12 and the second card slot 47 not greater than 0.5 mm, the installation difficulty can be reduced, and it can be avoided that it is difficult to install between the clamping plate 12 and the second card slot 47 due to too large an interference fit amount.

[0067] According to some embodiments of the present invention, referring to Figure 2 , the wall thickness of the side wall of the second card slot 47 is F, and the value of F is greater than or equal to 3.5 mm. For example, the wall thickness F of the side wall of the second card slot 47 can be 3.5 mm, 4 mm, 4.5 mm, etc. By making the wall thickness of the side wall of the second card slot 47 greater than or equal to 2 mm, sufficient allowance can be provided for the axial compression of the damping pad 35 by the side wall of the second card slot 47, so that the damping pad 35 has sufficient damping capacity.

[0068] According to some embodiments of the present invention, referring to Figure 2 , the wall thickness of the bottom wall of the second card slot 47 is G, and the value of G is greater than or equal to 2 mm. For example, the wall thickness G of the bottom wall of the second card slot 47 can be 2 mm, 2.5 mm, 3 mm, etc. By making the wall thickness of the bottom wall of the second card slot 47 greater than or equal to 2 mm, sufficient allowance can be provided for the radial compression of the damping pad 35 by the bottom wall of the second card slot 47, so that the damping pad 35 has sufficient damping capacity.
