Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0031] Therefore, the following detailed description of the embodiments of the present utility model is not intended to limit the scope of the present utility model claimed, but merely represents some embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0032] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] As Figures 1-5 shown, this implementation mode provides an adjustable vehicle frame turnover device, which includes a bottom plate 1. An adjusting and placing mechanism 2 is arranged on one side of the bottom plate 1. A limiting component 3 is arranged on the top of the bottom plate 1. A supporting component 4 is arranged on one side of the adjusting and placing mechanism 2. A fastening component 5 is arranged on one side of the adjusting and placing mechanism 2;

[0035] The adjusting and placing mechanism 2 includes a groove 201, a servo motor 202, a bidirectional lead screw 203, adjusting blocks 204, placing plates 205, a partition plate 206, universal wheels 207 and a pushing handle 208. The groove 201 is formed inside the bottom plate 1. The servo motor 202 is bolted to one side of the bottom plate 1. The bidirectional lead screw 203 is fixedly connected to the output end of the servo motor 202. The two adjusting blocks 204 are both threadedly connected to the outer wall of the bidirectional lead screw 203. The two placing plates 205 are respectively fixedly connected to the tops of the two adjusting blocks 204. The partition plate 206 is fixedly connected to one side of the placing plate 205. The four universal wheels 207 are all arranged at the bottom of the bottom plate 1. The pushing handle 208 is fixedly connected to one side of the bottom plate 1. When the servo motor 202 is started, the bidirectional lead screw 203 rotates, and the positions of the two adjusting blocks 204 and the placing plates 205 are adjusted according to the length of the electric bicycle frame. Then, the two ends of the electric bicycle frame are respectively placed on the two placing plates 205, and the partition plate 206 divides the placing plate 205 into two spaces, which can place two electric bicycle frames at the same time. Subsequently, the electric bicycle can be turned around through the universal wheels 207 and the pushing handle 208.

[0036] As Figure 3 and Figure 4 shown, considering that the cross beam in the middle of the electric bicycle frame will be suspended after being placed, resulting in shaking during its turnover, the limiting component 3 includes receiving columns 301, adjusting rods 302, rotating plates 303 and elastic sheets 304. The two receiving columns 301 are both fixedly connected to the top of the bottom plate 1. The adjusting rods 302 are slidably connected to the inside of the receiving columns 301. The rotating plates 303 are rotatably connected to the tops of the adjusting rods 302. The two elastic sheets 304 are both arranged on the tops of the rotating plates 303. After the electric bicycle frame is placed, the adjusting rods 302 are pulled to slide inside the receiving columns 301, and then the elastic sheets 304 are clamped on the frame cross beam. During turnover, the adjusting rods 302 are limited by the receiving columns 301, which can prevent the frame from shaking greatly, and the rotating plates 303 can adjust the angles of the elastic sheets 304 to facilitate clamping on cross beams at different angles.

[0037] As Figure 3 and Figure 5As shown, considering that the two ends of the frame will collide and rub during turnover, resulting in scratches, the support assembly 4 includes a placement groove 401, a hydraulic rod 402, a support plate 403, a moving groove 404, a bracket 405, and a friction pad 406. The two placement grooves 401 are both opened inside the placement plate 205. The hydraulic rod 402 is arranged on one side of the placement groove 401. The support plate 403 is arranged on the top of the hydraulic rod 402. The two moving grooves 404 are both opened inside the support plate 403. The bracket 405 is slidably connected inside the moving groove 404. The friction pad 406 is arranged on one side of the bracket 405. By starting the hydraulic rod 402, the height of the support plate 403 can be adjusted, and the bracket 405 can slide in the moving groove 404, facilitating the support of frames of different lengths. When placing the frame, its two ends can be respectively placed on the friction pads 406 on the bracket 405. The friction pads 406 can increase the friction between the bracket 405 and the frame and provide protection for it, preventing scratches from occurring.

[0038] As Figure 3 shown, considering the lack of means to fix the frame of the electric bicycle, the fastening assembly 5 includes a support frame 501, an elastic band 502, a hook 503, a fixing frame 504, and a support rod 505. The two support frames 501 are respectively fixedly connected to both sides of the placement plate 205. The elastic band 502 is arranged on one side of the support frame 501. The hook 503 is arranged at the other end of the elastic band 502. The fixing frame 504 is fixedly connected to the top of the partition plate 206. The two support rods 505 are both fixedly connected to one side of the fixing frame 504. After placing the frame, the elastic band 502 can be pulled to make it stretch and bypass the top of the frame, and then the hook 503 can be stuck on the support rod 505 on the fixing frame 504 to complete the fixation of the frame and prevent it from falling during turnover.

[0039] As Figure 1 shown, considering that when the placement plate 205 moves, its two ends lack support, two stabilizing grooves 6 are opened inside the bottom plate 1. Four stabilizing blocks 7 are respectively slidably connected inside the two stabilizing grooves 6. The top of the stabilizing block 7 is fixedly connected to the bottom of the placement plate 205. When the placement plate 205 moves, it will synchronously drive the stabilizing block 7 to slide in the stabilizing groove 6, and the stabilizing block 7 can provide support for the two ends of the placement plate 205.

[0040] As Figure 3 shown, considering that when the adjusting block 204 moves, it will be shaken by the rotation of the bidirectional lead screw 203. A stabilizing rod 8 is fixedly connected to one side of the groove 201. The two adjusting blocks 204 are both slidably connected to the outer wall of the stabilizing rod 8. When the adjusting block 204 moves due to the rotation of the bidirectional lead screw 203, the stabilizing rod 8 provides the stability of the adjusting block 204 during movement and prevents it from shaking during movement.

[0041] AsFigure 4 As shown, considering that the cross beam in the middle of the frame will be rubbed by the rotating plate 303, soft pads 9 are welded to the tops of the two rotating plates 303. The material of the soft pads 9 is rubber. After the elastic piece 304 clamps the cross beam in the middle of the frame, the soft pads 9 will be in direct contact with it to prevent the rotating plate 303 from scratching the cross beam.

[0042] Specifically, when the adjustable frame turnover device is in use: start the servo motor 202 to rotate the bidirectional lead screw 203, and adjust the positions of the two adjusting blocks 204 and the placement plate 205 according to the length of the electric bicycle frame. When placing the frame, the hydraulic rod 402 can be started according to the height of its two ends to adjust the height of the support plate 403, and the sliding bracket 405 can be slid according to the width of the frame so that it is clamped into the friction pad 406. Pull the adjusting rod 302 to make it slide in the receiving column 301, and then clamp the elastic piece 304 on the frame cross beam. During turnover, the adjusting rod 302 is limited by the receiving column 301, which can prevent the frame from shaking greatly. The rotating plate 303 can adjust the angle of the elastic piece 304 to facilitate clamping on cross beams at different angles, and the soft pad 9 can prevent the rotating plate 303 from scratching the cross beam. Finally, pull the elastic band 502 to make it stretch and bypass the top of the frame, and then hook the hook 503 on the support rod 505 on the fixed frame 504 to complete the fixation of the frame and prevent it from falling during turnover. Subsequently, the user can turnover the frame by pushing the handle 208 and the universal wheel 207.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
