[0060] Among them, the positioning structure includes a positioning plate 3 movably installed on one side of the positioning sleeve 2, and a threaded abutting rod 301 threadedly installed on the positioning plate 3. An installation component for disassembling and assembling the positioning plate 3 is arranged on the positioning sleeve 2. The threaded abutting rod 301 is in contact with one side of the support rod 1 of the electric tricycle, and is used to press on the surface of the support rod 1 of the electric tricycle. Rotating the threaded abutting rod 301 on the positioning plate 3, the threaded abutting rod 301 can press on the surface of the support rod 1 of the electric tricycle when rotating, so as to fix the position of the positioning sleeve 2 on the support rod 1 of the electric tricycle.

[0061] Specifically, the installation component includes a T-shaped block 303 arranged on the positioning plate 3 and a T-shaped groove 302 opened on the positioning sleeve 2 for preventing the T-shaped block 303 from shifting. The T-shaped block 303 is movably installed in the T-shaped groove 302. By inserting the T-shaped block 303 on the positioning plate 3 into the T-shaped groove 302, the positioning sleeve 2 and the positioning plate 3 can be connected. Pulling the positioning plate 3 to disassemble it from the positioning sleeve 2 enables the positioning plate 3 to be used for the installation of other positioning sleeves 2.

[0062] Embodiment Three:

[0063] On the basis of Embodiment 1, in order to further strengthen the support stability between the support rod 1 of the electric tricycle and the frame cross bar 202, a diagonal support structure for improving the stability of the support rod 1 of the electric tricycle is arranged on the positioning sleeve 2.

[0064] Among them, the diagonal support structure includes a mounting plate 5 arranged on the positioning sleeve 2, a T-shaped guiding strip 501 arranged on one side of the mounting plate 5, a slider 502 movably installed on the T-shaped guiding strip 501, and a support diagonal rod 503 arranged on one side of the slider 502. The support diagonal rod 503 is in contact with one side of the frame cross bar 202 and is used to support the frame cross bar 202 and the support rod 1 of the electric tricycle.

[0066] Working principle: When assembling the tricycle frame, first sleeve the positioning sleeve 2 on the electric tricycle support rod 1, and then insert the T-shaped block 303 on the positioning plate 3 into the T-shaped slot 302 to connect the positioning sleeve 2 with the positioning plate 3, and adjust its position on the electric tricycle support rod 1 by moving the positioning sleeve 2. After adjustment, the threaded push rod 301 on the positioning plate 3 can be rotated. The threaded push rod 301 can move by cooperating with the thread of the positioning plate 3 when rotating, and finally the threaded push rod 301 can be squeezed on the surface of the electric tricycle support rod 1, thereby fixing the position of the positioning sleeve 2 on the electric tricycle support rod 1 to prevent it from offsetting during the welding process. At this time, the electric tricycle support rod 1 can be The connection with the positioning sleeve 2, i.e., the weld 1 203, is welded to form a stable connection between the electric tricycle support rod 1 and the positioning sleeve 2. After completion, the threaded push rod 301 can be rotated in the opposite direction to disengage it from the extrusion on the electric tricycle support rod 1, and then the positioning plate 3 can be pulled to remove it from the positioning sleeve 2, so that the positioning plate 3 can be used for the installation of the positioning sleeve 2 at other positions, and then the frame cross bar 202 is sleeved on the positioning plug rod 201 on one side of the positioning sleeve 2. During the sleeve connection process, the frame cross bar 202 will drive the limiting card strip 206 to slide into the limiting card slot 205 on the positioning plug rod 201 to limit the moving distance of the frame cross bar 202. When the limiting card strip 206 completely slides into the limiting card slot 205, the frame cross bar 202 will also The L-shaped extrusion rod 4 is completely wrapped, and the nut 402 can be rotated at this time, and the nut 402 will drive the positive and negative screw rod 401 to rotate. Since the threads at both ends of the positive and negative screw rod 401 are opposite, the rotating positive and negative screw rod 401 can drive the two L-shaped extrusion rods 4 to move in the direction away from or towards each other at the same time by cooperating with the threads of the two L-shaped extrusion rods 4. Here, the positive and negative screw rods 401 can be rotated to drive the moving L-shaped extrusion rod 4 to be squeezed on the inner wall of the frame cross bar 202 to prevent the frame cross bar 202 from loosening from the positioning plug rod 201. At this time, welding can be performed at the connection between the positioning plug rod 201 and the frame cross bar 202, that is, the second weld 204, so that the positioning plug rod 201 and the frame cross bar 202 are connected. The slider 502 is then slid onto the T-shaped guide bar 501, and the position of the slider 502 on the T-shaped guide bar 501 is adjusted to make the support diagonal bar 503 contact one side of the frame cross bar 202. At this time, welding can be performed toward the weld seam 3 504 formed at the connection between the mounting plate 5 and the T-shaped guide bar 501, and the mounting plate 5 and the T-shaped guide bar 501 are fixed. Then, welding is performed toward the weld seam 4 505 formed at the connection between the support diagonal bar 503 and the frame cross bar 202 to ensure a stable connection between the frame cross bar 202 and the support diagonal bar 503. The mounting plate 5 can also be welded to the electric tricycle support bar 1 so that the support diagonal bar 503 can provide support for the electric tricycle support bar 1 and the frame cross bar 202.After all installations are completed, install another positioning sleeve 2 on the electric tricycle support rod 1 according to the same operation. After welding is completed, insert the positioning insertion rod 201 on the positioning sleeve 2 into the installed frame cross bar 202. After repeating the steps and completing the welding, the connection and fixation between the electric tricycle support rods 1 on both sides and the positioning sleeve 2 can be achieved.
