Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorbing component for an electric tricycle. Background Art

[0002] Shock absorbers on electric tricycles are crucial components for damping the rebound oscillations caused by springs absorbing shock and road impacts. They typically consist of springs, dampers, and connecting components. The springs absorb and store energy, while the dampers control the spring's rebound speed, thereby damping vibrations. Connectors connect the shock absorbers to the electric tricycle's frame.

[0003] In the prior art, during the long-term use of the shock absorber of an electric tricycle, the shock-absorbing spring on the shock absorber may gradually wear and damage due to continuous vibration and impact, resulting in a reduction in its shock-absorbing performance. However, when the shock-absorbing spring is disassembled and replaced, since the shock-absorbing spring itself still has a certain elastic force, it is easy to bounce off if suddenly released, generating a large impact force, posing a threat to the operator.

[0056] 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.

[0057] Example 1:

[0058] like Figures 1 to 5 As shown, the utility model provides a shock-absorbing assembly for an electric tricycle, comprising: a shock-absorbing damper 1, the shock-absorbing damper 1 comprising a piston rod 101 slidably mounted inside the shock-absorbing damper 1, and a shock-absorbing spring 102 movably sleeved on the shock-absorbing damper 1 and the piston rod 101 for compression buffering.

[0059] In order to gradually release the elastic force of the shock-absorbing spring 102 when removing the shock-absorbing spring 102 and prevent it from popping out instantly, a limiting structure for blocking the shock-absorbing parts on the shock-absorbing damper 1 is arranged on the shock-absorbing damper 1, and an adjustment structure for gradually releasing the elastic force of the shock-absorbing parts in the shock-absorbing damper 1 is arranged on the limiting structure.

[0060] The limiting structure includes a fixing frame 2 fixedly mounted on the shock absorber 1, an adjusting screw 201 slidably mounted inside the fixing frame 2, a telescopic pull rod 202 slidably mounted inside the adjusting screw 201, a mounting cover 203 arranged at one end of the telescopic pull rod 202, a connecting seat 204 arranged on one side of the mounting cover 203 for connecting to the frame of the electric tricycle, a linkage gear 205 rotatably mounted on one side of the fixing frame 2 for limiting the moving distance of the adjusting screw 201, and the adjusting screw 201 threadedly mounted on the linkage gear 205. The interior of the linkage gear 205 is provided with a threaded hole adapted to the adjusting screw 201. The fixing frame 2 is in contact with one end of the shock-absorbing spring 102, and the other end of the shock-absorbing spring 102 is in contact with the inner wall of the mounting cover 203. During shock absorption, the squeezed connecting seat 204 and the mounting cover 203 will drive the piston rod 101 to move inside the shock-absorbing damper 1, and at the same time compress the shock-absorbing spring 102, thereby achieving the effect of buffering and shock absorption. When the mounting cover 203 moves, it can drive the telescopic pull rod 202 to slide in the adjusting screw 201.

[0061] Among them, the limiting structure also includes a limiting slide hole 206 opened inside the adjusting screw 201, a limiting slide 207 arranged at one end of the telescopic rod 202 to prevent the telescopic rod 202 from loosening from the adjusting screw 201, the limiting slide 207 is slidably installed inside the limiting slide hole 206, a guide strip 208 arranged on the inner wall of the adjusting screw 201, and a guide groove 209 opened inside the limiting slide 207 to prevent the adjusting screw 201 from rotating, the guide strip 208 is slidably installed in the guide groove 209, the telescopic rod 202 can drive the limiting slide 207 to slide in the limiting slide hole 206, and the limiting slide hole 206 can slide on the guide bar 208 through the guide groove 209, so that the adjusting screw 201 and the telescopic rod 202 can only slide and move, and cannot rotate.

[0062] Among them, the adjustment structure includes a fixed bracket 3 arranged on one side of the fixed bracket 2, an annular frame 301 arranged on the fixed bracket 3, a rotating ring 302 rotatably installed on one side of the annular frame 301, a linkage gear ring 303 arranged on one side of the rotating ring 302 for transmission, the linkage gear ring 303 is engaged with the linkage gear 205, and a rotation limiting component is arranged on the linkage gear ring 303 and the linkage gear 205 for limiting the position of the linkage gear ring 303 and the linkage gear 205 during rotation. Rotating the rotating ring 302 can drive the linkage gear ring 303 to rotate, and the rotating linkage gear ring 303 can drive the linkage gear 205 to rotate by engaging with the linkage gear 205. When the linkage gear 205 rotates, it can make the adjusting screw 201 slide inside the fixed frame 2 by cooperating with the thread of the adjusting screw 201.

[0063] Specifically, the rotation limiting assembly includes two annular grooves 1 304 provided inside the rotating ring 302 and the linkage gear ring 303, two fixing rings 1 305 arranged on one side of the annular frame 301 and the fixed frame 2, the two fixing rings 1 305 are respectively rotatably installed in the two annular grooves 1 304, two annular grooves 2 306 provided inside the fixed frame 2 and the fixed bracket 3, two fixing rings 2 307 arranged on both sides of the linkage gear 205, the two fixing rings 2 307 are respectively rotatably installed in the two annular grooves 2 306, when the rotating ring 302 and the linkage gear ring 303 rotate, they can rotate on the corresponding fixing ring 1 305 through the set annular grooves 1 304, thereby preventing the rotating ring 302 and the linkage gear ring 303 from loosening from between the fixed frame 2 and the fixed bracket 3, and when the linkage gear 205 rotates, it can drive the fixing ring 2 307 to rotate in the corresponding annular groove 2 306, thereby limiting the rotation position of the linkage gear 205.

[0064] Example 2:

[0065] On the basis of Example 1, in order to facilitate installation and removal of the mounting cover 203 on the piston rod 101 , a mounting structure for fixing the limiting structure on the shock absorbing damper 1 is arranged on the limiting structure.

[0066] The fixing nut 401 is then screwed back on the mounting screw 4 after passing through the mounting cover 203 and the connecting seat 204.

[0067] Specifically, the positioning assembly includes a positioning groove 402 opened inside the mounting cover 203, a positioning sleeve 403 movably mounted on the piston rod 101, and a fixing nut 401 arranged on the inner wall of the mounting screw 4. When installing the mounting cover 203, the positioning sleeve 403 can be mounted on the piston rod 101 to avoid offset between the mounting cover 203 and the piston rod 101.

[0068] Working principle:

[0069] During shock absorption, the squeezed connecting seat 204 and the mounting cover 203 will drive the piston rod 101 to move inside the shock absorber 1, and at the same time compress the shock absorbing spring 102, which plays a role in buffering and shock absorption. When the mounting cover 203 moves, it can drive the telescopic pull rod 202 to slide in the adjusting screw 201, and at the same time, the telescopic pull rod 202 can drive the limiting slide 207 to slide in the limiting sliding hole 206, and the limiting sliding hole 206 can slide on the guide bar 208 through the guide slot 209, thereby making the adjusting screw 201 and the telescopic pull rod 202 in contact with each other. The cam 303 is connected to the mounting screw 401 by rotating the fixing nut 401 so as to release the connection restriction between the mounting cover 203 and the piston rod 101. The cam 303 is connected to the mounting screw 401 by rotating the fixing nut 401. When the fixing nut 401 is connected to the mounting screw 401, the cam 303 is connected to the mounting screw 401. When the fixing nut 401 is connected to the mounting screw 401, the connection restriction between the mounting cover 203 and the piston rod 101 is released. The cam 303 is connected to the mounting screw 401 by rotating the fixing nut 401. When the fixing nut 401 is connected to the mounting screw 401, the cam 303 is connected to the mounting screw ... The bracket 3 is loose, and the continuously rotating linkage gear ring 303 can drive the linkage gear 205 to rotate by meshing with the linkage gear 205. When the linkage gear 205 rotates, it can drive the fixing ring 207 to rotate in the corresponding annular groove 206, thereby limiting the rotation position of the linkage gear 205. The continuously rotating linkage gear 205 can make the adjusting screw 201 slide inside the fixing bracket 2 by cooperating with the thread of the adjusting screw 201, so that the adjusting screw 201 moves toward the mounting cover 203. At this time, the damping spring 10 2, the movement of the adjusting screw 201 will push the mounting cover 203 to move, so that the mounting cover 203 drives the positioning sleeve 403 to separate from the piston rod 101, and finally the continuously moving adjusting screw 201 will separate from the fixing frame 2. At this time, the mounting cover 203 can be completely separated from the piston rod 101, and the shock-absorbing spring 102 can be pulled out for replacement, so as to avoid the shock-absorbing spring 102 being ejected instantly due to its elastic force when being disassembled, and the elastic force of the shock-absorbing spring 102 can be slowly released as the mounting cover 203 moves.

[0070] During installation, the shock absorbing spring 102 is sleeved on the piston rod 101 and the shock absorbing damper 1, so that one end thereof contacts one side of the fixing frame 2. Then, the adjusting screw 201 is aligned with the socket on the fixing frame 2 and inserted into the threaded hole in the linkage gear 205. At the same time, the shock absorbing spring 102 is sleeved on the positioning sleeve 403, so that one end of the shock absorbing spring 102 is located in the positioning groove 402, and the positioning sleeve 403 is sleeved on the piston rod 101. At this time, rotating the rotating ring 302 in the reverse direction can drive the linkage gear 205 to rotate in the reverse direction, thereby driving the adjusting screw 201. When the adjusting screw 201 moves in the reverse direction, it can pull the telescopic rod 202 to move through the limiting slide 207, so that the telescopic rod 202 pulls the mounting cover 203 to move toward the shock absorber 1, and finally the mounting cover 203 can re-compress the shock absorber spring 102, and the mounting screw 4 can pass through the mounting cover 203 and the connecting seat 204 again. At this time, the fixing nut 401 is re-tightened on the mounting screw 4 after passing through the mounting cover 203 and the connecting seat 204, and the mounting cover 203 can be re-fixed on the piston rod 101 to complete the installation operation.
