Description

Technical Field

[0001] The utility model relates to the technical field of front fork shock absorbing structures, in particular to a front fork shock absorbing structure for an electric bicycle. Background Art

[0002] Electric bicycles are a mode of operation that combines human power and electricity. They are almost the same as bicycles in appearance and still retain the pedal design of bicycles. The front fork of electric bicycles is generally used to connect and fix the front wheel to the handlebars. Due to uneven road conditions encountered during driving, in order to ensure riding comfort, the front fork must have a shock-absorbing structure.

[0003] According to the description of an electric bicycle pneumatic shock-absorbing front fork disclosed on the patent website (authorization announcement number: CN 219447235U), "the utility model belongs to the field of front fork shock-absorbing technology, especially an electric bicycle pneumatic shock-absorbing front fork, including an upper tube, a shoulder fork is fixedly connected to the bottom of the upper tube, a stroke tube is sleeved at both ends of the shoulder fork, a piston is fixedly connected to the bottom of the stroke tube, and a symmetrically distributed sleeve is provided at the bottom of the shoulder fork, a shock-absorbing spring is fixedly installed inside the sleeve, and one end of the stroke tube connected to the piston extends to the inner wall of the sleeve. The electric bicycle pneumatic shock-absorbing front fork connects the fork bridge with the left and right sleeves as a whole, enhances the stability of the overall structure of the left and right front forks, realizes the synchronous operation of the left and right front forks, and is conducive to improving the stability of the vehicle during riding. By setting a buffer spring device, the impact force generated by the bumping of the vehicle body is shared, and the riding comfort is improved. The pressure control of the buffer spring is realized by the tension bolts set on the outer surface of the upper positioning ring, and the rider can flexibly adjust the shock absorption performance according to different road conditions and different weights."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can achieve synchronous shock absorption on the left and right sides by connecting the sleeves on the left and right sides, so that the riding process of the electric bicycle becomes stable. However, in actual use, the internal positions of the shock-absorbing springs inside the left and right sleeves of the shock-absorbing front fork are fixed, resulting in that the shock-absorbing pressure cannot be adjusted, making the front fork of the electric bicycle prone to shaking even on a flat road surface, and unable to adjust according to the bumpy road conditions, affecting riding comfort. Therefore, it is necessary to improve a front fork shock-absorbing structure for electric bicycles to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a front fork shock absorbing structure for an electric bicycle to solve the problems raised in the above background technology.

[0012] Preferably, the second spring is arranged outside the second telescopic rod, and the second sliding piston is slidably installed inside the sealing cylinder, thereby improving stability.

[0013] Preferably, the pressure regulating assembly includes a circular bottom plate, which is fixedly mounted on the bottom of the sealing cylinder, a rotating head is rotatably mounted inside the circular bottom plate, a gear 1 is fixedly mounted on the bottom of the rotating head, a small handle is fixedly mounted on the bottom of the gear 1, a gear 2 is meshed on the outside of the gear 1, a threaded rod is rotatably mounted on the top of the gear 2, and a threaded sleeve is mounted on the external thread of the threaded rod, so as to facilitate the adjustment of the shock-absorbing pressure through the pressure regulating assembly.

[0015] Compared with the prior art, the utility model provides a front fork shock absorbing structure for an electric bicycle, which has the following beneficial effects:

[0016] 1. The front fork shock-absorbing structure of the electric bicycle has an adjustable shock-absorbing mechanism. During use, the small handle is turned to make the gear one drive the gear two to rotate. At this time, the threaded rod drives the threaded sleeve to rotate, so that the threaded sleeve can drive the connecting plate to rise and fall, and the pressure of the air pressure shock-absorbing component is adjusted. When riding on a flat ground, the threaded sleeve is raised to avoid a large rise and fall of the sliding piston one, which affects the riding experience. When riding on a relatively bumpy ground, the threaded sleeve is lowered to improve the shock-absorbing effect. The front fork shock-absorbing mechanism that can be adjusted according to actual conditions can adapt to the external environment and improve the riding comfort.

During use, when it is adjusted and ridden on flat ground, the shock-absorbing effect at the bottom is reduced. When encountering an uneven road surface, the connecting frame will slide on the outside of the side pressure rod 1. At this time, the damping 1, the telescopic rod 1 and the spring 1 can provide shock absorption, thereby avoiding the situation where the shock absorption effect at the bottom is insufficient and affects the riding experience.
