Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 An electric motorcycle shock-absorbing rocker arm front fork includes a front fork 1, a height adjustment component 2 is provided in the middle of the front fork 1, a fixing component 3 is provided at the bottom of the height adjustment component 2, and a shock-absorbing component 4 is installed at the bottom of the front fork 1.

[0027] Please see Figure 1-4The height adjustment assembly 2 includes a first mounting plate 201 fixedly connected to the middle of the front fork 1, a second mounting plate 202 sleeved on the top of the front fork 1, a lifting rod 203 fixedly connected to the inner wall of the second mounting plate 202, a mounting groove 204 opened on the top of the first mounting plate 201, a threaded rod 205 installed on the inner wall of the mounting groove 204, a limit ring 206 fixedly connected to the bottom outer wall of the threaded rod 205, and the threaded rod 205 rotatably connected to the inner wall of the mounting groove 204 through the limit ring 206. The bottom inner wall of the lifting rod 203 is threaded, and the bottom inner wall of the lifting rod 203 is threadedly connected to the threaded rod 205. A knob 207 is fixedly connected to the bottom surface. By rotating the knob 207, the threaded rod 205 is rotated, and the lifting rod 203 moves up or down along with the thread of the threaded rod 205. While the lifting rod 203 moves, it also moves the second mounting plate 202, thereby achieving quick adjustment of the overall height without tools. Since motorcycles inevitably need to wade through water during daily riding, a corrugated sleeve can be set at the mounting groove 204 to increase the service life of the device. Alternatively, grease can be periodically applied between the limiting tooth ring 303 and the gear 301 to prevent aging caused by dust and rainwater immersion.

[0028] Please see Figure 4-6 The fixing component 3 includes a gear 301 fixedly connected to the bottom outer wall of the threaded rod 205. A protrusion 302 is symmetrically mounted on the bottom inner wall of the mounting groove 204. A limiting tooth ring 303 corresponding to the tooth shape of the gear 301 is mounted on the bottom inner wall of the mounting groove 204. The inner wall of the limiting tooth ring 303 engages with the outer wall of the gear 301. A limiting groove 304 is symmetrically opened on the outer wall of the limiting tooth ring 303. The limiting tooth ring 303 is slidably connected to the protrusion 302 through the limiting groove 304. Two slots 305 are opened on the left outer wall of the limiting tooth ring 303. A mounting frame 306 is fixedly connected to the bottom left side of the first mounting plate 201. A mounting post 307 is fixedly connected to the inner wall of the mounting frame 306. A spring 308 is sleeved on the outer wall of the mounting post 307. A limiting slider is inserted into the right end of the mounting post 307. 310, the top outer wall of the limiting slider 310 is slidably connected to the inner wall of the mounting frame 306, the outer wall of the mounting post 307 is fitted with a sleeve 309, the right end of the sleeve 309 is fixedly connected to the left side of the limiting slider 310, the right outer wall of the limiting slider 310 is engaged with the slot 305, the bottom of the mounting frame 306 is provided with a slot 311, the slot 311 is slidably connected to the bottom outer wall of the limiting slider 310, the limiting tooth ring 303 is made of metal, and a magnet is set inside the limiting slider 310, which can effectively prevent the limiting slider 310 from being displaced by vibration or shaking. The limiting tooth ring 303 limits the gear 301, and the limiting slider 310 limits the limiting tooth ring 303, thereby preventing the threaded rod 205 from rotating during riding and ensuring the rider's riding safety.

[0029] Please see Figure 7 The shock absorption assembly 4 includes a mounting bracket 401. The mounting bracket 401 is fixedly connected to the bottom outer wall of the front fork 1. The inner wall of the mounting bracket 401 is fixedly connected to the top outer wall of the shock absorber 402. The bottom end of the shock absorber 402 is fixedly connected to the inner wall of the rocker arm 403. The rocker arm 403 has an axle mounting hole 405 at one end away from the front fork 1. The other end of the rocker arm 403 is fixedly connected to a fixing post 404. The rocker arm 403 is fixedly connected to the bottom inner wall of the front fork 1 through the fixing post 404. The front fork 1 transmits vibration to the shock absorber 402 through the rocker arm 403, thereby absorbing the vibration caused by uneven road surface during driving and reducing vehicle bumps.

[0030] Working principle: When height adjustment is required, first pull the top of the limit slider 310 away from the slot 305 at the top of the limit toothed ring 303, push the limit toothed ring 303 upward into the bottom inner wall of the mounting groove 204, release the limit slider 310 and insert it into the slot 305 at the bottom of the limit toothed ring 303, then rotate the knob 207 to rotate the threaded rod 205. The lifting rod 203 moves up or down with the thread of the threaded rod 205. While the lifting rod 203 moves, it drives the second mounting plate 202 to move together, thus completing the height adjustment.

[0031] When the lifting rod 203 moves to the appropriate position, pull the top of the limiting slider 310 away from the slot 305 at the bottom of the limiting tooth ring 303. The limiting tooth ring 303 will fall to the top surface of the knob 207 due to gravity. If it cannot fall under the action of gravity, the limiting tooth ring 303 can be manually slid down. At this time, the limiting tooth ring 303 engages with the gear 301. Then, the limiting slider 310 is released, and the compressed spring 308 returns to its original shape, pushing the limiting slider 310 into the slot 305 at the top of the limiting tooth ring 303, thus limiting the limiting tooth ring 303 and preventing it from moving upward. The protrusion 302 at the bottom of the inner wall of the mounting groove 204 further limits the limiting tooth ring 303, preventing it from rotating. Because the tooth shape of the inner wall of the limiting tooth ring 303 corresponds to the tooth shape of the gear 301, the gear 301 cannot rotate, thereby completing the fixation of the height adjustment component 2 and ensuring that the threaded rod 205 will not rotate due to vibration or shaking during riding, thus ensuring the rider's safety.
