[0024] This utility model provides, for example Figure 1 The positioning plate structure of the electric vehicle folding rack shown includes an installation mechanism 1 for installing and fixing the electric vehicle folding rack.

[0025] Adjustment mechanism 2 is located at the bottom of mounting mechanism 1 and is used to connect mounting mechanism 1 to the mounting part at the rear of electric vehicle.

[0026] To allow the device to be easily adjusted according to the dimensions of the mounting location at the rear of the electric vehicle, such as Figure 1-2 and Figure 4 As shown, the adjustment mechanism 2 includes an adjustment knob 201. A rotating plate 202 is fixedly sleeved on the outer side of the adjustment knob 201. Traction plates 203 are rotatably installed on both sides of the top of the rotating plate 202. Movable plates 205 are provided at the bottom of the ends of the two traction plates 203 away from the rotating plate 202. Fixed grooves 206 are provided on the inner walls of both sides of the movable plates 205. Fastening bolts 207 that are threadedly connected to the rear mounting part of the electric vehicle are movably inserted into the inner wall of the fixed grooves 206. Rotating the adjustment knob 201 causes the rotating plate 202 to rotate. Through the traction action of the traction plates 203, the position of the two movable plates 205 can be easily adjusted according to the needs. The setting of the fixed grooves 206 allows the fastening bolts 207 to be easily adjusted.

[0027] To facilitate the connection and fixation of the installation mechanism 1 to the folding rack, such as... Figure 1-3As shown, the installation mechanism 1 includes an installation plate 101. The installation plate 101 has an H-shaped cross-section when viewed from above. The inner walls of both ends of the installation plate 101 are provided with installation holes 102. The inner walls of the installation holes 102 are threaded with connecting bolts 103 that are threaded to the folding rack. The inner walls of both ends of the installation plate 101 are provided with movable grooves 104. The connecting bolts 103 penetrate the bottom inner wall of the folding rack and are threaded to the inner walls of the adjacent installation holes 102, so that the folding rack can be stably installed on the top of the installation plate 101.

[0028] In order to keep the adjustment mechanism 2 stable during the adjustment process, such as Figure 2-4 As shown, each of the two movable plates 205 has a movable seat 204 fixedly installed on its top. The top of each movable seat 204 is rotatably connected to the inner wall of the end of each traction plate 203 away from the rotating plate 202. The outer walls of each movable seat 204 are movably connected to the inner walls of adjacent movable slots 104. Two fixed slots 206 at the same end are respectively set on both sides of the transverse portion of the mounting plate 101. The width of the fixed slot 206 is smaller than the diameter of the screw head of the fastening bolt 207. The movable slot 104 can limit the movement of adjacent movable seats 204, so that the movable plate 205 remains stable during adjustment. At the same time, the movement of the fastening bolt 207 on the inner wall of the fixed slot 206 allows the adjustment mechanism 2 to be easily adjusted according to the size of the rear mounting part of the electric vehicle.

[0029] To prevent the adjustment mechanism 2 from affecting the installation of the folding rack, such as Figure 2 As shown, the sum of the height of the horizontal portion of the mounting plate 101 and the height of the traction plate 203 is the same as the height of the vertical portion. The length of the mounting plate 101 is the same as the length of the folding rack. The vertical portion of the mounting plate 101 can support the folding rack and prevent the traction plate 203 from affecting the installation of the folding rack.

[0030] When installing the folding rack, the device is installed at the rear of the electric vehicle. Rotating the knob 201 causes the rotating plate 202 to rotate, which in turn moves the two traction plates 203. Under the traction of the two traction plates 203, the two movable plates 205 can move relative to or away from each other at the bottom of the mounting plate 101. The distance between the two movable plates 205 can be easily adjusted according to the dimensions of the installation location. Simultaneously, the two movable slots 104 limit the movement of the two movable seats 204, ensuring the stability of the movable plates 205 during movement and preventing them from shifting during adjustment. Once the two movable plates 205 are moved to the top of the electric vehicle's rear mounting section, the fixing slot 206 aligns with the hole in the inner wall of the mounting location. Then, the fastening bolts 207 penetrate the inner wall of the fixing slot 206 and are threadedly connected to the hole in the inner wall of the mounting location. This design ensures a tight connection between the device and the rear mounting area of ​​the electric vehicle. The fixed groove 206 allows the adjustment mechanism 2 to be easily adjusted according to the dimensions of the mounting area. After the device is installed, the folding rack is placed on top of the mounting plate 101, aligning the holes at both ends of its bottom with the mounting holes 102 on the inner walls of the mounting plate 101. Then, connecting bolts 103 are used to penetrate the inner wall of the bottom of the folding rack and threadedly connect to the inner wall of the adjacent mounting holes 102, ensuring a tight connection between the folding rack and the device. This improves the adaptability of the folding rack, allowing it to be easily adjusted according to the dimensions of the rear mounting area of ​​the electric vehicle. This facilitates easy installation and disassembly of the folding rack by workers, improving installation efficiency. This embodiment specifically solves the problem in the prior art where the folding rack cannot be easily adjusted according to the dimensions of the rear mounting area of ​​the electric vehicle, resulting in low installation and disassembly efficiency.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
