Detailed Implementation

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Please see Figure 1-6 As shown, this embodiment provides a mounting structure for a lidar, which is mounted on a lidar 8. Two connecting rods 801 are provided on one side of the lidar 8, and a pressing plate 802 is provided at the end of each connecting rod 801. This mounting structure includes:

[0042] The fixed box 2 has two toothed plates 5 that slide relative to each other inside the fixed box 2, and the fixed box 2 is equipped with a shock-absorbing mechanism 9 that is compressed by the displacement of the compression plate 802.

[0043] The gear 4 meshes with the toothed plate 5, and the upper part of the fixed box 2 is elastically fitted with a pressing element 3 that drives the two gears 4 to rotate in opposite directions;

[0044] Two pairs of clamping plates 7 are slidably fitted within the fixed box 2. A connecting rod 801 is slidably fitted between one pair of clamping plates 7. Both the clamping plates 7 and the toothed plate 5 are made of aluminum alloy with a tensile strength ≥310MPa, meeting the requirements for lightweight design and strength to prevent deformation during long-term use.

[0045] A pair of clamping plates 7 are driven to slide relative to each other. The outer gear ring 6 meshes with the toothed plate 5 and is located on the periphery of the extrusion plate 802.

[0046] One application of this embodiment is as follows: When the lidar 8 is displaced by vibration, the lidar 8 compresses the shock-absorbing mechanism 9 through the connecting rod 801 and the compression plate 802, and the shock-absorbing mechanism 9 absorbs the vibration energy to achieve shock absorption. When the lidar 8 needs to be replaced or maintained, firstly, the pressing part 3 is pressed, driving two gears 4 to rotate in opposite directions; the gears 4 drive the toothed plates 5 meshing with them to slide, causing the two toothed plates 5 to move away from each other; then, the toothed plates 5 drive the outer gear ring 6 meshing with them to rotate, and the rotation of the outer gear ring 6 drives a pair of clamping plates 7 to move away from each other, thereby releasing the constraint on the compression plate 802 sliding out of the fixing box 2, realizing the separation of the lidar 8 from the fixing box 2; when the pressing part 3 is released, its elastic reset causes the gears 4 to reverse, and then the clamping plates 7 are reset again through the linkage of the toothed plates 5 and the outer gear ring 6. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0047] Through the meshing transmission of gear 4, external gear ring 6 and gear plate 5, and the linkage design of external gear ring 6 driving clamping plate 7, it is easy to quickly release the constraint on the extrusion plate 802 to slide out of the fixing box 2, so as to realize the disassembly, replacement and maintenance of lidar 8; at the same time, the elastic reset characteristics of pressing part 3 are used to quickly restore the state of clamping plate 7, thereby improving the convenience of disassembly and assembly of lidar 8; the shock absorption mechanism 9 absorbs the vibration energy transmitted by extrusion plate 802, thereby improving the impact resistance of lidar 8.

[0048] like Figure 1 As shown, in this embodiment, a mounting plate 1 is installed on the lower side of the fixing box 2, and the lidar 8 is slidably fitted on the top of the mounting plate 1. Optionally, the mounting plate 1 has a plurality of vertical mounting holes 101, which penetrate the mounting plate 1. The plurality of mounting holes 101 facilitates the adaptation to the fixing requirements of different mounting surfaces; combined with the mounting plate 1, it enhances the load-bearing stability of the lidar 8.

[0049] like Figure 2-6As shown, the fixing box 2 in this embodiment is equipped with two fixing rings 205. The fixing rings 205 are located around the connecting rod 801. One end face of the fixing ring 205 is provided with a sliding groove 206, and the adjacent sides of the pair of clamping plates 7 are both located in the sliding groove 206. Optionally, the fixing box 2 is provided with a movable groove 203. One end of the fixing ring 205 is embedded in one side of the movable groove 203, and the clamping plate 7 is slidably engaged with one side of the movable groove 203. The fixing box 2 is provided with two insertion holes 201 on one side adjacent to the lidar 8. The insertion holes 201 communicate with the movable groove 203. The fixing ring 205 is located around the insertion holes 201, and the connecting rod 801 passes through the insertion holes 201 laterally. Optionally, the toothed plate 5 is slidably engaged with the lower side of the movable groove 203, and both sides of the movable groove 203 are provided with side grooves 204. The edge of the toothed plate 5 is slidably engaged with the side grooves 204. The sliding direction of the clamping plate 7 is limited by the slide groove 206, which improves the sliding stability of the clamping plate 7; the sliding constraint of the toothed plate 5 by the side groove 204 reduces the risk of transmission deviation; and the insertion of the pressing plate 802 and the connecting rod 801 into the fixing box 2 is facilitated by the cooperation of the insertion hole 201 and the fixing ring 205.

[0050] like Figure 3 , 5 As shown, in this embodiment, the outer gear ring 6 has two arc-shaped grooves 601 on one end face adjacent to the fixed ring 205. The arc-shaped grooves 601 gradually transition towards the outer edge of the outer gear ring 6. A protrusion 701 located in the arc-shaped groove 601 is provided on one side of the clamping plate 7. The maximum sliding stroke of the clamping plate 7 is 10-50mm, ensuring the reliability of the limiting / releasing compression plate 802. Optionally, two support rings 207 are installed on one side of the movable groove 203. The outer gear ring 6 is located between the support ring 207 and the fixed ring 205. One end face of the support ring 207 has an annular groove 208, and one end face of the outer gear ring 6 has a rotating ring 602 that is rotatably fitted in the support ring 207. Optionally, a first bearing 10 is installed on the circumference of the rotating ring 602, and the first bearing 10 is embedded in the annular groove 208. The rotation of the outer gear ring 6 is converted into the linear opening and closing motion of the two clamping plates 7 by the cooperation of the protruding post 701 and the arc groove 601, while limiting the sliding distance of the clamping plates 7; the stability of the rotation of the outer gear ring 6 is improved by the cooperation of the annular groove 208 and the rotating ring 602; and the friction loss of the outer gear ring 6 is reduced by the cooperation of the first bearing 10.

[0051] like Figure 4 As shown, in this embodiment, both ends of the gear 4 are provided with a rotating shaft 401. Optionally, a second bearing 402 is mounted on the circumference of the rotating shaft 401. The second bearing 402 is embedded in one side of the movable groove 203. Both the first bearing 10 and the second bearing 402 are miniature deep groove ball bearings. The rotating shaft 401 improves the stability of the rotation of the gear 4; at the same time, the second bearing 402 reduces the frictional loss of the gear 4.

[0052] like Figure 3As shown, the shock absorption mechanism 9 in this embodiment includes a shock absorber 901 mounted on one side of the movable groove 203. A first spring 903 is fitted around the periphery of the shock absorber 901, and a support ring 207 is located around the periphery of the first spring 903. The damping coefficient of the shock absorber 901 is 500–1500 N·s / m, and the stiffness coefficient of the first spring 903 is 50–200 N / mm. The range of damping coefficient and stiffness coefficient matches the typical weight (e.g., 1–5 kg) and common vibration frequency (e.g., 10–100 Hz) of the lidar 8 to effectively absorb impact energy. Optionally, the output shaft of the shock absorber 901 is fixedly fitted with a pressure plate 902, an external gear ring 6 is located around the periphery of the pressure plate 902, a compression plate 802 is located between the pressure plate 902 and the clamping plate 7, and the first spring 903 is mounted between the compression plate 802 and one side of the movable groove 203. The composite damping design of the shock absorber 901 and the first spring 903 improves the absorption effect of the impact energy of the extrusion plate 802; the pressure plate 902 increases the contact area between the extrusion plate 802, the shock absorber 901 and the first spring 903, and improves the balance of the forces they bear.

[0053] like Figure 2 , 4 As shown, the pressing component 3 in this embodiment includes a double-sided rack 302 that meshes with two gears 4, and a pressing plate 301 is mounted on the upper side of the double-sided rack 302. Optionally, the upper side of the fixed box 2 is provided with a lifting groove 202 that communicates with the movable groove 203, and the middle part of the double-sided rack 302 is slidably engaged in the lifting groove 202. Optionally, a second spring 303 located on the periphery of the double-sided rack 302 is installed between the pressing plate 301 and the fixed box 2. By synchronously driving the two gears 4 to rotate in opposite directions through the double-sided rack 302, the symmetrical displacement of the two gear plates 5 is ensured; the vertical movement of the double-sided rack 302 is guided by the lifting groove 202, improving the stability of the pressing operation; and the elastic reset of the second spring 303 quickly restores the initial position of the pressing component 3, improving the convenience of operation.
