Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0052] Embodiment 1:

[0053] As Figures 1 to 7As shown in the figure, the present utility model provides a reinforcement structure for a vehicle frame, including: an electric tricycle vehicle frame 1 for bearing the weights of various components of the tricycle, and a front diagonal rod 2 arranged on the electric tricycle vehicle frame 1 for supporting the front components of the electric tricycle vehicle frame 1.

[0054] In order to provide auxiliary support for the front diagonal rod 2 when it is damaged and prevent further damage, a reinforcement structure for auxiliary support when the front diagonal rod 2 is damaged is arranged on the front diagonal rod 2. The reinforcement structure includes a splicing structure for splicing on the front diagonal rod 2 and a limiting structure for enhancing the stability between the splicing structure and the front diagonal rod 2.

[0055] Among them, the splicing structure includes a positioning clamp one 3 and a positioning clamp two 301 movably installed on the front diagonal rod 2, a guide frame 302 arranged on one side of the positioning clamp two 301, a U-shaped reinforcement rod 303 arranged on one side of the positioning clamp one 3. The U-shaped reinforcement rod 303 is slidably installed on the inner wall of the guide frame 302, two positioning plates 304 arranged on one side of the positioning clamp one 3 and the positioning clamp two 301. Rubber pads for increasing friction are arranged on the inner walls of the positioning clamp one 3 and the positioning clamp two 301. The rubber pads are in contact with the outer surface of the front diagonal rod 2. The positioning clamp one 3 and the positioning clamp two 301 are sleeved on the front diagonal rod 2, so that the positioning clamp one 3 and the positioning clamp two 301 are respectively located on both sides of the damaged position. By arranging rubber pads on the inner walls of the positioning clamp one 3 and the positioning clamp two 301, it can prevent the positioning clamp one 3 and the positioning clamp two 301 from slipping when clamping.

[0056] Among them, the limiting structure includes an installation frame 4 movably installed on the positioning plate 304, an extrusion strip 402 slidably installed on the inner wall of the installation frame 4, an adjusting screw rod 403 rotatably installed on one side of the extrusion strip 402. The adjusting screw rod 403 is threadedly installed on the inner wall of the installation frame 4. A thread adapted to the adjusting screw rod 403 is provided on the inner wall of the installation frame 4, a positioning groove 404 opened on the positioning plate 304, and the extrusion strip 402 is movably installed in the positioning groove 404. A guiding component arranged on the extrusion strip 402 for restricting the moving direction of the extrusion strip 402. A plurality of installation frames 4 are respectively sleeved on the two positioning plates 304 of the positioning clamp one 3 and the positioning clamp two 301. Rotating the adjusting screw rods 403 on both sides can make them move through the threaded cooperation with the installation frame 4, so that the rotating and moving adjusting screw rod 403 pushes the extrusion strip 402 to move. The moving extrusion strip 402 will be inserted into the positioning grooves 404 on the two positioning plates 304 to prevent loosening, and at the same time, it can squeeze the two positioning plates 304 towards each other, and further make the positioning clamp one 3 and the positioning clamp two 301 clamp on the front diagonal rod 2.

[0057] Specifically, the guiding assembly includes a guiding slider 406 arranged on one side of the extrusion bar 402 and a guiding chute 405 opened on the inner wall of the mounting frame 4 for guiding the moving direction of the guiding slider 406. The guiding slider 406 is slidably installed in the guiding chute 405. The moving extrusion bar 402 will drive the guiding slider 406 to slide in the guiding chute 405, thereby restricting the moving direction of the extrusion bar 402.

[0058] Embodiment 2:

[0059] On the basis of Embodiment 1, in order to further improve the connection stability between the positioning clamp 1 3 and the positioning clamp 2 301 and prevent the mounting frame 4 from slipping off, a blocking structure for preventing the limiting structure from loosening is arranged on the positioning clamp 1 3 and the positioning clamp 2 301.

[0060] Among them, the blocking structure includes two blocking plates 407 respectively arranged on both sides of the positioning plate 304, a U-shaped plug board 401 movably installed on the positioning plate 304. The U-shaped plug board 401 is in contact with one side of the two blocking plates 407. The U-shaped plug board 401 is located on one side of the mounting frame 4 for blocking the mounting frame 4. The U-shaped plug board 401 is sleeved on the corresponding positioning plate 304 so that it is located between the blocking plate 407 and the mounting frame 4 to block the mounting frame 4.

[0061] Embodiment 3:

[0062] On the basis of Embodiment 1, in order to enable the distance between the positioning clamp 1 3 and the positioning clamp 2 301 to be adjusted according to the damaged position of the front diagonal rod 2, an adjusting structure for adjusting the position of the splicing structure is arranged on the splicing structure.

[0063] Among them, the adjusting structure includes a limiting screw rod 5 arranged on the U-shaped reinforcing rod 303, a threaded adjusting ring 501 rotatably installed on one side of the guiding frame 302. The threaded adjusting ring 501 is threadedly installed on the limiting screw rod 5, and a pressing component arranged on the guiding frame 302 for pressing the U-shaped reinforcing rod 303. The limiting screw rod 5 is slidably installed on the inner wall of the guiding frame 302. During the rotation of the threaded adjusting ring 501, it can move on the limiting screw rod 5 through the threaded cooperation with the limiting screw rod 5, so that the moving threaded adjusting ring 501 drives the guiding frame 302 to move.

[0064] Specifically, the pressing component includes an extrusion screw rod 503 threadedly installed on the inner wall of the guiding frame 302 for extruding the U-shaped reinforcing rod 303. The extrusion screw rod 503 is in contact with one side of the U-shaped reinforcing rod 303. When the extrusion screw rod 503 presses on the U-shaped reinforcing rod 303, its position can be restricted. When the extrusion screw rod 503 is rotated, it can rotate and move on the inner wall of the guiding frame 302 through the threaded cooperation with the guiding frame 302, so that the extrusion screw rod 503 is separated from the extrusion of the U-shaped reinforcing rod 303.

[0065] Among them, the adjusting structure further includes a limiting ring 502 arranged on one side of the guide frame 302 for preventing the threaded adjusting ring 501 from detaching from the guide frame 302. The limiting ring 502 is rotatably installed on the inner wall of the threaded adjusting ring 501. When the threaded adjusting ring 501 rotates, it will rotate on the limiting ring 502. By setting the limiting ring 502, the threaded adjusting ring 501 can be prevented from loosening from the guide frame 302.

[0066] The utility model also provides an electric tricycle, including a reinforcing structure of the frame.

[0067] Working principle: When the current front inclined rod 2 is damaged during use, the positioning clamp one 3 and the positioning clamp two 301 can be sleeved on the front inclined rod 2, so that the positioning clamp one 3 and the positioning clamp two 301 are respectively located on both sides of the damaged position. Then, a plurality of mounting frames 4 are respectively sleeved on the two positioning plates 304 of the positioning clamp one 3 and the positioning clamp two 301. When the adjusting screw rods 403 on both sides are rotated, the adjusting screw rods 403 can move through the threaded fit with the mounting frames 4 during rotation, so that the rotating and moving adjusting screw rods 403 rotate and push the pressing strips 402 to move on one side of the pressing strips 402. Finally, the pressing strips 402 on both sides are inserted into the positioning grooves 404 on the two positioning plates 304 to prevent loosening. At the same time, under the continuous movement of the pressing strips 402 on both sides, the two positioning plates 304 can be pressed towards each other, so that the positioning clamp one 3 and the positioning clamp two 301 clamp on the front inclined rod 2. By arranging rubber pads on the inner walls of the positioning clamp one 3 and the positioning clamp two 301, the positioning clamp one 3 and the positioning clamp two 301 can be prevented from slipping when clamping. After completion, the U-shaped insertion plate 401 is sleeved on the corresponding positioning plate 304 and located between the blocking plate 407 and the mounting frame 4 to block the mounting frame 4, so that the mounting frame 4 can be prevented from slipping off the positioning plate 304. After installation, the guide frame 302 and the U-shaped reinforcing rod 303 arranged on one side of the positioning clamp one 3 and the positioning clamp two 301 can provide support for the front inclined rod 2 to prevent further damage to the front inclined rod 2.

[0068] Before installation, the extrusion screw 503 can be rotated. When the extrusion screw 503 rotates, it can rotate and move on the inner wall of the guide frame 302 through the thread fit with the guide frame 302, so that the extrusion screw 503 is disengaged from the extrusion of the U-shaped reinforcing rod 303. At this time, the thread adjusting ring 501 can be rotated. The thread adjusting ring 501 will rotate on the limiting ring 502. By setting the limiting ring 502, it can prevent the thread adjusting ring 501 from loosening from the guide frame 302. During the rotation of the thread adjusting ring 501, it can move on the limiting screw rod 5 through the thread fit with the limiting screw rod 5, so that the moving thread adjusting ring 501 drives the guide frame 302 to move. When the guide frame 302 moves, it can slide on the U-shaped reinforcing rod 303 and drive the positioning clamp two 301 to move, thereby being able to adjust the distance between the positioning clamp two 301 and the positioning clamp one 3, so that it can be adjusted and installed according to the damage position of the upper bracket on the electric tricycle frame 1.
