DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1:

[0045] like Figures 1 to 5 As shown, the utility model provides an electric tricycle frame structure, comprising: an electric tricycle frame 1 and a supporting structure arranged on the electric tricycle frame 1 for tilting and supporting one side of the electric tricycle frame 1, the supporting structure comprising a tilting rod structure for tilting one side of the electric tricycle frame 1.

[0046] Among them, the tilting rod structure includes a fixed seat 2 arranged on the electric tricycle frame 1, an L-shaped movable rod 201 rotatably installed inside the fixed seat 2, a U-shaped frame 202 slidably installed inside the L-shaped movable rod 201, an adjusting slide 203 slidably sleeved on the L-shaped movable rod 201, a support rod 204 arranged on one side of the adjusting slide 203, and a support roller 205 rotatably installed on one side of the support rod 204 for supporting the electric tricycle frame 1. The support roller 205 is used in conjunction with the L-shaped movable rod 201 and the U-shaped frame 202. The U-shaped frame 202 is flipped to drive the support roller 205 to contact the ground. The U-shaped frame 202 is continuously pressed down to make the support roller 205 roll on the ground, while supporting one side of the electric tricycle frame 1.

[0047] Example 2:

[0048] On the basis of Example 1, in order to save more effort when pressing the U-shaped frame 202 and adjust the support height of the electric tricycle frame 1 when it is tilted, the support structure also includes a length adjustment structure for adjusting the length of the pressing position of the tilting rod structure and a height adjustment structure for adjusting the support height of the tilting rod structure.

[0049] Among them, the length adjustment structure includes a positioning socket 3 provided inside the L-shaped movable rod 201, a positioning screw 301 movably installed in the positioning socket 3, and several mounting screw holes 302 provided inside the U-shaped frame 202. The positioning screw 301 is threadedly installed in the corresponding mounting screw hole 302, and a guide component is arranged on the U-shaped frame 202 to limit the moving direction of the U-shaped frame 202. The positioning screw 301 is rotated and unscrewed from the positioning socket 3 and the mounting screw hole 302 to release the connection restriction between the U-shaped frame 202 and the L-shaped movable rod 201. After that, the U-shaped frame 202 can be pulled to an appropriate length, and the positioning screw 301 is re-screwed into the corresponding positioning socket 3 and the mounting screw hole 302 to fix the position of the L-shaped movable rod 201 and the U-shaped frame 202.

[0050] Specifically, the guide assembly includes limiting grooves 303 opened on both sides of the U-shaped frame 202, and two limiting blocks 304 arranged on the inner wall of the L-shaped movable rod 201 for limiting the moving distance of the U-shaped frame 202. The two limiting blocks 304 are respectively slidably installed in the two limiting grooves 303. When the U-shaped frame 202 moves, it can slide on the limiting blocks 304 through the limiting grooves 303, thereby limiting the moving direction of the U-shaped frame 202, and at the same time preventing the U-shaped frame 202 from slipping off the L-shaped movable rod 201.

[0051] Among them, the height adjustment structure includes a fixed screw 4 arranged inside the L-shaped movable rod 201, a threaded ring 401 rotatably installed on one side of the adjustment slide 203, and the threaded ring 401 rotatably installed on one side of the adjustment slide 203. When the threaded ring 401 rotates, it can drive the adjustment slide 203 to slide on the L-shaped movable rod 201. The moving adjustment slide 203 can drive the support rod 204 to move, so that the support rod 204 drives the support roller 205 to move, thereby adjusting the distance between the support roller 205 and the L-shaped movable rod 201.

[0052] The height adjustment structure further includes a linkage component arranged on the threaded collar 401 and the adjustment slide 203 so that the adjustment slide 203 can move along with the threaded collar 401 .

[0053] Specifically, the linkage assembly includes a restriction ring 402 arranged on one side of the threaded collar 401, and an annular groove 403 provided inside the adjusting slide 203 for preventing the threaded collar 401 from loosening from one side of the adjusting slide 203. The restriction ring 402 is rotatably installed in the annular groove 403. The threaded collar 401 on both sides can drive the restriction ring 402 to rotate in the annular groove 403. When the threaded collar 401 moves, it can drive the adjusting slide 203 to move through the restriction ring 402.

[0054] Example 3:

[0055] On the basis of Example 1, in order to facilitate the flipping of the L-shaped movable rod 201 and place it on the side of the electric tricycle frame 1 to avoid interference with driving, a limiting structure for limiting the angle of the tilting rod structure is arranged on the tilting rod structure.

[0056] Among them, the limiting structure includes an L-shaped rod 5 arranged on one side of the adjusting slide 203, and a slot 501 opened inside the fixed seat 2. The L-shaped rod 5 is movably installed in the slot 501. After the L-shaped movable rod 201 is flipped over and located on the side of the electric tricycle frame 1, the L-shaped rod 5 can be driven to be inserted into the slot 501 by rotating the threaded ring 401, so that the angle of the L-shaped rod 5 can be limited.

[0057] Working principle:

[0058] When in use, the positioning screw 301 can be rotated and unscrewed from the positioning socket 3 and the mounting screw hole 302 to release the connection restriction between the U-shaped frame 202 and the L-shaped movable rod 201, and then the U-shaped frame 202 can be pulled out. After the U-shaped frame 202 is pulled out to a suitable length, the positioning screw 301 can be screwed back into the corresponding positioning socket 3 and the mounting screw hole 302 to re-fix the position of the L-shaped movable rod 201 and the U-shaped frame 202, and then the threaded collars 401 on both sides can be rotated. The rotating threaded collar 401 can drive the limiting ring 402 to rotate in the annular groove 403, and the threaded collar 401 can rotate by cooperating with the thread of the fixed screw rod 4. The horizontal movement causes the moving threaded collar 401 to drive the adjusting slide 203 to slide on the L-shaped movable rod 201 through the limiting ring 402. The sliding adjusting slide 203 will drive the L-shaped plug rod 5 to disengage from the slot 501, thereby releasing the angle restriction between the fixed seat 2 and the L-shaped movable rod 201. At the same time, the moving adjusting slide 203 can drive the supporting rod 204 to move, so that the supporting rod 204 drives the supporting roller 205 to move. After adjustment, the U-shaped frame 202 can be turned over to drive the supporting roller 205 to contact the ground. The U-shaped frame 202 is continuously pressed down to make the supporting roller 205 roll on the ground, and at the same time, one side of the electric tricycle frame 1 is supported, Figure 2 In the state of the U-shaped frame 202, one side of the electric tricycle frame 1 is tilted up, which is convenient for inspecting the components on the bottom side of the electric tricycle frame 1 or replacing the tire on the raised side. Before tilting the electric tricycle frame 1, the position of the supporting roller 205 can be adjusted by continuously rotating the threaded ring 401, and the extension length of the U-shaped frame 202 is adjusted to adjust the support height of the electric tricycle frame 1.

[0059] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
