Description

Technical Field

[0001] This utility model relates to the field of sensor installation technology, and in particular to a mounting bracket for automotive autonomous driving sensors. Background Technology

[0002] In autonomous driving systems, millimeter-wave radar, as a key sensor, is widely installed in locations such as the front bumper to detect the distance, speed, and orientation of obstacles in front of the vehicle. It is a core component for functions such as adaptive cruise control and collision warning. The common installation method for millimeter-wave radar on the front bumper is to first drill holes in the pre-set positions on the bumper, and then use adhesive to fix the radar body into the holes. When it is necessary to replace the radar, adhesive residue makes disassembly difficult, and forcibly peeling it off can easily damage the bumper body. Before pasting, the area on the bumper to be pasted needs to be dusted, which increases the time cost. At the same time, the adhesive is prone to aging and failure due to environmental factors such as temperature and humidity, which may cause the radar to loosen. Utility Model Content

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1

[0032] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a mounting bracket for an autonomous driving sensor in a car. The mounting bracket includes a main component 1, including a bumper 11. A through hole 11-1 is provided on the bumper 11, and a radar 12 is installed on the bumper 11. The through hole 11-1 is made at an appropriate position on the bumper 11 using a special drilling tool. The radar 12 detects the distance, speed, and direction of obstacles by emitting millimeter waves, and is not affected by weather conditions such as rain, snow, and fog. It is used for adaptive cruise control. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0033] Mounting component 2, located on bumper 11, includes mounting component 21, which is configured to mount radar 12 on bumper 11. Mounting component 21 is provided with locking component 22, which is used to assist mounting component 21 in completing the installation of radar 12.

[0034] Mounting component 21 includes a sleeve 211 located within a through hole 11-1. The sleeve 211 is fixed to the through hole 11-1 by welding. A rotating ring 212 is connected to the sleeve 211 by a bearing. The rotating ring 212 can rotate relative to the sleeve 211. A moving groove 211-1 is provided on the sleeve 211. A moving block 213 is slidably arranged in the moving groove 211-1. The moving groove 211-1 is rectangular and corresponds to the shape of the moving block 213. A clamping plate 214 is fixed on the moving block 213. The moving block 213 is used to drive the clamping plate 214 to move. The clamping plate 214 is used to clamp the radar 12 and fix the radar 12 inside the sleeve 211, thereby ensuring that the radar 12 can be stably fixed on the bumper 11.

[0035] A slider 215 is fixed on the other side of the moving block 213. An arc-shaped groove 212-1 is provided on the rotating ring 212. The slider 215 slides in the arc-shaped groove 212-1. In the initial state, the slider 215 will be located on the side of the arc-shaped groove 212-1 close to the edge of the rotating ring 212. At this time, the moving block 213 is completely located in the moving groove 211-1, and the clamping plate 214 will not obstruct the radar 12 from being inserted into the sleeve 211.

[0036] Since the slider 215 can only slide within the arc groove 212-1, during the sliding process, a portion of the moving block 213 is always located within the moving groove 211-1, thereby ensuring the stability of the movement of the moving block 213.

[0037] When the rotating ring 212 is rotated, the slider 215 will slide along the arc groove 212-1 and move away from the edge of the rotating ring 212. The slider 215 will synchronously drive the moving block 213 to move. The moving block 213 will gradually move out of the moving groove 211-1, thereby causing the clamping plate 214 to move towards the radar 12 and gradually fit against the outer surface of the radar 12, thus clamping the radar 12 and preventing the radar 12 from shifting its position inside the sleeve 211.

[0038] When it is necessary to replace the radar 12, rotate the rotating ring 212 in the opposite direction to move the clamp 214 away from the radar 12. Then the radar 12 can be taken out, and the new radar 12 can be put into the sleeve 211 and fixed.

[0039] Example 2

[0040] Reference Figures 4-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, there are four moving blocks 213, four clamping plates 214, and four sliders 215. By setting four sets, the radar 12 is clamped in a ring from four directions to ensure the stability of the clamping and prevent the radar 12 from shifting inside the sleeve 211 during driving, which would affect its use.

[0042] Specifically, the locking component 22 includes a movable ring 221 located on one side of the rotating ring 212. One side of the rotating ring 212 is stepped. The movable ring 221 can slide on the outside of the rotating ring 212, but the two will not rotate relative to each other. A locking pin 222 is fixed on one side of the movable ring 221. A locking groove 211-2 is provided on the sleeve 211. The locking pin 222 can cooperate with the locking groove 211-2. When the two are engaged, the position of the movable ring 221 and the rotating ring 212 relative to the sleeve 211 will be locked, so that the rotating ring 212 cannot continue to rotate. At this time, the position of the slider 215 in the arc groove 212-1 is also locked. The position of the movable block 213 and the clamping plate 214 is locked, so that the clamping plate 214 is always in close contact with the outer surface of the radar 12.

[0043] Specifically, there are multiple locking slots 211-2.

[0044] Four locking pins 222 are fixed on the moving ring 221, each locking pin 222 corresponding to two locking slots 211-2. The locking slots 211-2 are divided into two groups, each group containing four locking slots 211-2. In the initial state, the four locking pins 222 are engaged with one group of locking slots 211-2. At this time, the clamping plate 214 is located away from the radar 12 and will not obstruct the radar 12 from being inserted into the sleeve 211. When the locking pins 222 are engaged with the other group of locking slots 211-2, the clamping plate 214 is in close contact with the surface of the radar 12, thereby ensuring a stable connection between the radar 12 and the sleeve 211.

[0045] Specifically, a guide post 223 is fixed on the rotating ring 212, and a guide groove 221-1 is provided on the moving ring 221, with the guide post 223 inserted into the guide groove 221-1.

[0046] The guide post 223 consists of two cylindrical sections. The cylindrical section of the guide post 223 that is farther away from the rotating ring 212 has a larger size, and the guide groove 221-1 corresponds to the other cylindrical section with a smaller size. This ensures that the moving ring 221 can slide smoothly outside the rotating ring 212 without separating from the rotating ring 212.

[0047] The cooperation between the guide post 223 and the guide groove 221-1 restricts the moving ring 221 from rotating relative to the rotating ring 212, and the two can only slide relative to each other.

[0048] Example 3

[0049] Reference Figures 3-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, a spring 224 is fixed to one side of the moving ring 221, and the other end of the spring 224 is fixed to the rotating ring 212. The spring 224 applies a continuous pulling force to the moving ring 221. Under the action of the spring 224, the moving ring 221 will be located at the position closest to the bumper 11, thereby ensuring that the locking pin 222 can be inserted into the locking groove 211-2, thus restricting the rotating ring 212 from rotating.

[0051] When it is necessary to rotate the rotating ring 212, pull the moving ring 221 to move it away from the rotating ring 212. The spring 224 is stretched, which causes the locking pin 222 to separate from the locking groove 211-2.

[0052] Specifically, there are four guide posts 223 and four springs 224.

[0053] Specifically, a baffle 216 is fixed on the sleeve 211. The baffle 216 is annular and hollow inside. The baffle 216 is set to limit the radar 12 when it is inserted into the sleeve 211. When inserting, it is necessary to ensure that the rear end face of the radar 12 fits against the baffle 216.

[0054] Specifically, a friction block 217 is fixed on the clamping plate 214. There are multiple friction blocks 217. The friction blocks 217 are made of rubber and are used to increase the friction between the clamping plate 214 and the outer surface of the radar 12, while preventing the clamping plate 214 from making direct hard contact with the outer surface of the radar 12.

[0055] Specifically, a wire 13 is provided on one side of the radar 12, and the wire 13 can pass through the baffle 216.

[0056] When in use, use a special drilling tool to make a through hole 11-1 at an appropriate position on the bumper 11, insert the sleeve 211 into the through hole 11-1 and fix it to the bumper 11 by welding. At this time, the moving block 213 is completely located in the moving groove 211-1, and the clamp 214 will not obstruct the insertion of the radar 12. Then, insert the radar 12 into the sleeve 211 and the rotating ring 212, ensuring that the rear end face of the radar 12 fits against the baffle 216.

[0057] Then, pull the moving ring 221 to move it away from the rotating ring 212. The spring 224 is stretched, causing the locking pin 222 to separate from the locking groove 211-2. Then, rotate the moving ring 221 to drive the rotating ring 212 to rotate, causing the locking pin 222 to move closer to the other locking groove 211-2. When the locking pin 222 is coaxial with the other locking groove 211-2, release the moving ring 221. The spring 224 drives the moving ring 221 to reset, and the locking pin 222 engages with the locking groove 211-2 again, restricting the rotation of the moving ring 221 and the rotating ring 212.

[0058] During the rotation of the rotating ring 212, the slider 215 will slide along the arc groove 212-1 and move away from the edge of the rotating ring 212. The slider 215 will synchronously drive the moving block 213 to move. The moving block 213 will gradually move outward from the moving groove 211-1, thereby causing the clamping plate 214 to move towards the radar 12. The friction block 217 on the clamping plate 214 will gradually come into contact with the outer surface of the radar 12 and exert pressure on the surface. Under the action of friction, the radar 12 will be clamped, thereby completing the installation of the radar 12 and preventing the radar 12 from shifting inside the sleeve 211 during driving, which would affect the use of the radar 12.

[0059] When it is necessary to replace the radar 12, rotate the rotating ring 212 in the opposite direction to move the clamp 214 away from the radar 12. Then the radar 12 can be taken out, and the new radar 12 can be put into the sleeve 211 and fixed.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
