[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: like Figures 1 to 6 As shown, this utility model provides a conveyor belt for assembling an electric tricycle, including: an electric tricycle frame 1 and a base 2, and a conveying structure arranged on the base 2 for conveying the electric tricycle frame 1.

[0019] The conveying structure comprises two sets, including a support frame 201 positioned above the base 2, two sets of conveyor belt supports 202 symmetrically slidably mounted on the support frame 201, several drive shafts 203 uniformly rotatably mounted on the two sets of conveyor belt supports 202, conveyor belts 204 mounted on the corresponding drive shafts 203, several linkage shafts 205 rotatably mounted inside the support frame 201 and movably passing through the conveyor belt supports 202, several sprockets 206 slidably mounted on the corresponding linkage shafts 205, chains 207 mounted on two corresponding sprockets 206, and an L-shaped baffle 208 positioned on one side of the conveyor belt supports 202 and blocking the sides of the sprockets 206. The drive motor 209 at the top has two sprockets 210 mounted on its output end and corresponding linkage shaft 205, respectively. The chain 211 mounted on the two sprockets 210 drives the drive motor 209 to rotate. Through the transmission action of the chain 211, the other sprocket 210 and the corresponding linkage shaft 205 rotate synchronously. The linkage shaft 205 drives the transmission shaft 203 and sprocket 206 to rotate. Then, through the chain 207, all sprockets 206 and linkage shaft 205 rotate, which finally drives the conveyor belt 204 to make a circular motion, stably transporting the electric tricycle frame 1 placed on the two conveyor belts 204 to each assembly station.

[0020] The conveying structure also includes a strip groove 212 formed on the linkage shaft 205, and two limiting sliders 213 slidably installed in the strip groove 212. The two limiting sliders 213 are respectively fixed on the inner walls of the drive shaft 203 and the sprocket 206. When the linkage shaft 205 rotates, it can drive the drive shaft 203 and the sprocket 206 to rotate through the cooperation of the strip groove 212 and the limiting sliders 213.

[0021] Example 2: Based on Embodiment 1, a support structure is arranged on the base 2 in order to support the electric tricycle frame 1.

[0022] The support structure includes an electric push rod 3 arranged on the support frame 201 and a support plate 301 installed at the telescopic end of the electric push rod 3. When the electric tricycle frame 1 is transported to the designated assembly station, that is, directly above the support plate 301, the electric push rod 3 is activated to push the support plate 301 up, lift the frame and provide stable support, so that the staff can conveniently carry out the assembly of parts.

[0023] Example 3: Based on Example 1, an adjustment structure is arranged on the conveying structure to facilitate the adjustment of the distance between the two sides of the conveying structure.

[0024] The adjustment structure includes two bearing seats 4 symmetrically arranged on the support frame 201, a bidirectional lead screw 401 rotatably installed inside the two bearing seats 4, a threaded seat 402 threaded onto the bidirectional lead screw 401, two linkage rods 403 rotatably installed on both sides of the threaded seat 402 and rotatably connected to the conveyor belt bracket 202 at the other end, an adjustment motor 404 arranged on the corresponding bearing seat 4 and connected to the bidirectional lead screw 401 at its output end, a guide groove 405 opened on the inner wall of the support frame 201, and a guide assembly arranged on the conveyor belt bracket 202. When the adjustment motor 404 is turned on, the bidirectional lead screw 401 is driven to rotate. The threaded seat 402 slides along the bidirectional lead screw 401 under the limit of the guide groove 405. The linkage rods 403 pull the two conveyor belt brackets 202 to move in a direction that is closer to or further away from each other, so as to achieve precise adjustment of the spacing of the conveyor belt 204.

[0025] Specifically, the guide assembly includes a T-slot 406 formed on the inner wall of the support frame 201, and two T-slides 407 symmetrically slidably installed in the T-slot 406. The two T-slides 407 are respectively fixed below the two conveyor belt supports 202. When the conveyor belt support 202 moves, it drives the T-slides 407 to slide in the T-slot 406 to ensure that the movement direction is stable and does not deviate.

[0026] Working principle: By turning on the drive motor 209, the corresponding sprocket 210 can be rotated. Through the transmission cooperation between the two sprockets 210 and the chain 211, the other sprocket 210 drives the corresponding linkage shaft 205 to rotate. The linkage shaft 205 can drive the corresponding sprocket 206 and the drive shaft 203 to rotate through the cooperation between the limit slider 213 and the slot 212. Through the transmission cooperation between the two sprockets 206 and the chain 207, all sprockets 206 and the linkage shaft 205 can be driven to rotate together, thereby driving the other drive shafts 203 to rotate. When rotated, the 03 mechanism drives the conveyor belt 204 in a circular motion. During use, the electric tricycle frame 1 can be placed on the two conveyor belts 204. The movement of the conveyor belts 204 transports the electric tricycle frame 1. When transported to the designated workstation, i.e., the support plate 301, the support plate 301 can be raised by activating the electric push rod 3. The raised support plate 301 supports the electric tricycle frame 1, facilitating the assembly of parts onto the frame. After assembly, the support plate 301 is lowered, and the electric tricycle frame 1 is placed back on the conveyor belt 204 for transport to the next assembly station. By activating the corresponding adjusting motor 404, the bidirectional lead screw 401 can be rotated. The bidirectional lead screw 401 can slide within the guide groove 405 through its threaded engagement with the threaded seat 402. The guide groove 405 prevents the threaded seat 402 from shifting position. The moving threaded seat 402 can move the two linkage rods 403 on both sides. The two linkage rods 403 rotate between the two conveyor belt supports 202, simultaneously pulling the two conveyor belt supports 202 to move further apart or closer together, adjusting the distance between the two conveyor belt supports 202 and the conveyor belt 204 to adapt to different needs. The electric tricycle frame 1 of the specified size has a movable conveyor belt support 202 that can drive the T-shaped slider 407 to slide within the T-shaped groove 406, thereby preventing the conveyor belt support 202 from deviating in the direction of movement. During the adjustment of the conveyor belt support 202, the drive shaft 203 and the L-shaped baffle 208 will move. Under the obstruction of the L-shaped baffle 208, the sprocket 206 can move with the conveyor belt support 202, so that when the drive shaft 203 and the sprocket 206 move, they can drive the corresponding limit slider 213 to slide within the strip groove 212, thus not affecting the normal rotation of the sprocket 206 and the drive shaft 203.

[0027] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
