DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1-5 The utility model provides a technical solution: a front fork of an electric vehicle that is easy to fold, comprising a fork arm 1, a first connecting rod 2 is connected to one side of the surface of the fork arm 1, a shock absorbing mechanism 3 is arranged on the inner side of the fork arm 1, a folding mechanism 4 is arranged on one side of the surface of the first connecting rod 2, and a second connecting rod 5 is hingedly connected to one side of the surface of the first connecting rod 2;
[0022] The folding mechanism 4 includes a threaded rotating rod 401, a return spring 402, a limiting groove 403, a resisting groove 404, a clamping groove 405, a resisting block 406, a pushing block 407 and a clamping block 408. The threaded rotating rod 401 is connected to one side of the surface of the first connecting rod 2, and the return spring 402 is embedded in the interior of the first connecting rod 2. The limiting groove 403 is provided in the interior of the first connecting rod 2, and the resisting groove 404 is provided on one side of the surface of the second connecting rod 5. The clamping groove 405 is provided on one side of the surface of the second connecting rod 5. One end of the threaded rotating rod 401 is connected to the resisting block 406, and the return spring 402 is embedded in the interior of the first connecting rod 2. The limiting groove 403 is provided in the interior of the first connecting rod 2. One end of the spring 402 is connected to a push block 407, and one side of the surface of the push block 407 is connected to a clamping block 408. When folding the front fork, the user first rotates the threaded rotating rod 401, and then the threaded rotating rod 401 drives the retaining block 406 to disengage from the retaining groove 404, and then pushes the push block 407. Thereafter, the push block 407 moves and squeezes the return spring 402 inside the limiting groove 403. The return spring 402 is compressed and deformed under the force, and at the same time, the push block 407 drives the clamping block 408 to disengage from the clamping groove 405. When the clamping block 408 is completely separated from the clamping groove 405, the front fork can be folded.
[0023] Furthermore, the return spring 402 is embedded in the limit groove 403, and two groups of return springs 402 are arranged. Through the arrangement of the return spring 402, when in use, the return spring 402 can be squeezed and compressed by the push block 407 when the block 408 is separated from the slot 405, thereby providing elastic force for the reset of the block 408.
[0024] Furthermore, the size of the stop block 406 is consistent with that of the stop groove 404, and one end of the push block 407 is embedded in the limiting groove 403. Through the setting of the stop block 406, when in use, the stop block 406 can be stuck in the stop groove 404 in the unfolded state, thereby improving the stability of the first connecting rod 2 and the second connecting rod 5 in the unfolded state.
[0025] Further, one end of the clamping block 408 is dimensionally compatible with the clamping groove 405. There are two sets of clamping blocks 408. Through the arrangement of the clamping blocks 408, during use, in the non-folded state, the clamping blocks 408 are stuck in the clamping grooves 405. Acting together with the abutting blocks 406, the stability of the connection between the first connecting rod 2 and the second connecting rod 5 is enhanced. Stuck in the clamping grooves 405, acting together with the abutting blocks 406, the stability of the connection between the first connecting rod 2 and the second connecting rod 5 is enhanced.
[0026] Further, the shock absorption mechanism 3 includes a guide rod 301, a slider 302, a chute 303, a buffer spring 304, a vertical rod 305, and an extrusion block 306. The guide rod 301 is connected inside the fork arm 1. The slider 302 is fitted inside the fork arm 1. The chute 303 is opened inside the fork arm 1. One end of the guide rod 301 is connected through the buffer spring 304. One side of the surface of the slider 302 is connected with the vertical rod 305. One side of the surface of the slider 302 is connected with the extrusion block 306. Through the arrangement of the guide rod 301, the slider 302, the chute 303, the buffer spring 304, the vertical rod 305, and the extrusion block 306, during use, when the electric bicycle is running, the force generated by the vibration of the wheel is transmitted to the slider 302 through the vertical rod 305. Subsequently, the slider 302 drives the extrusion block 306 inside the chute 303 to move along the guide rod 301. Then, the extrusion block 306 presses the buffer spring 304 at one end of the guide rod 301. At this time, the buffer spring 304 is compressed and deformed under the force, so as to absorb the force from the wheel through the compression of the buffer spring 304, and further achieve shock absorption.
[0027] Further, one end of the guide rod 301 is connected through the extrusion block 306. There are two sets of buffer springs 304. Through the arrangement of the guide rod 301 and the buffer spring 304, during use, the guide rod 301 provides guidance for the movement of the slider 302 and the extrusion block 306 to ensure their movement along a specific direction. At the same time, it is also the support point of the buffer spring 304.
[0028] Further, the extrusion block 306 is fitted inside the chute 303. There are two sets of extrusion blocks 306. Through the arrangement of the extrusion blocks 306, during use, the extrusion blocks 306 press the buffer spring 304 under the drive of the slider 302, convert the vibration energy of the wheel into the elastic potential energy of the buffer spring 304, and achieve the shock absorption effect.
[0029] Working principle: First, when the electric bicycle is running, the force generated by the vibration of the wheel is transmitted to the slider 302 through the vertical rod 305. Subsequently, the slider 302 drives the extrusion block 306 inside the chute 303 to move along the guide rod 301 under the action of force. Then, the extrusion block 306 presses the buffer spring 304 at one end of the guide rod 301. At this time, the buffer spring 304 is compressed and deformed under the action of force, so as to absorb the force from the wheel through the compression of the buffer spring 304, thereby achieving buffering. Then, when folding the front fork, first the user rotates the threaded rotating rod 401, and then the threaded rotating rod 401 drives the abutting block 406 to disengage from the abutting groove 404. Subsequently, the push block 407 is pushed. Then, the push block 407 moves and presses the return spring 402 inside the limiting groove 403. The return spring 402 is compressed and deformed under the action of force. At the same time, the push block 407 drives the clamping block 408 to disengage from the clamping groove 405. When the clamping block 408 completely disengages from the clamping groove 405, the front fork can be folded.
[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
