Technical Field

[0001] The invention belongs to the technical field of electric bicycle accessories, in particular to a 165mm electric bicycle hydraulic shock absorber. Background Art

[0002] Electric bicycles are Battery As an auxiliary energy source, it is a mechatronic personal bicycle equipped with a motor, controller, battery, control components such as the turning handle and brake handle, and a display instrument system. Transportation .

[0003] However, the existing 165mm electric bicycle hydraulic shock absorber has a simple structure and no shock absorption strength adjustment mechanism is set inside, which is not convenient for adjusting the shock absorber pressure and cannot be applied to electric bicycles of different qualities, and has poor applicability. Secondly, the existing 165mm electric bicycle hydraulic shock absorber only uses a single shock absorption mechanism inside, which cannot effectively perform shock absorption on the electric bicycle, and the shock absorption effect is poor. Summary of the invention

[0004] The purpose of the present invention is to provide a 165mm electric bicycle hydraulic shock absorber to solve the problem that there is no shock absorption strength adjustment mechanism inside the shock absorber, which makes it inconvenient to adjust the shock absorber pressure and the shock absorption effect of the shock absorber is poor.

[0005] The technical solution adopted by the present invention is as follows: a 165mm electric bicycle hydraulic shock absorber, comprising a fixed ring and a hydraulic cylinder, a first mounting plate is arranged at the inner center of the fixed ring, a limiting slide column penetrating the fixed ring is welded to the outer side of the first mounting plate, and a shock-absorbing spring is sleeved on the outer side of the limiting slide column, a lifting sleeve is welded at the top center of the fixed ring, a hydraulic cylinder is slidably embedded in the lifting sleeve, an adjusting stud penetrating the fixed ring is rotatably connected to the bottom of the hydraulic cylinder via a rotating shaft, a threaded sleeve is welded to the outside of the adjusting stud inside the fixed ring, a plunger rod is slidably embedded in the hydraulic cylinder, and a second mounting plate is welded to the top of the plunger rod.

[0006] A first mounting hole is provided at the inner center of the first mounting plate, and a plurality of second mounting holes are provided inside the second mounting plate, and the plurality of second mounting holes are distributed in a ring array about the horizontal center line of the second mounting plate.

[0007] There are a plurality of groups of limit sliding posts, and the plurality of groups of limit sliding posts are distributed in a ring array about the horizontal center line of the first mounting plate.

[0008] Wherein, a limiting sliding sleeve is welded inside the fixing ring and outside the shock absorbing spring.

[0009] Wherein, the bottom end of the plunger rod is located inside the hydraulic cylinder and is provided with a plunger block, and the outer diameter of the plunger block is equal to the inner diameter of the hydraulic cylinder.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0011] 1. In the present invention, the shock absorber of the electric bicycle adopts a shock absorbing strength adjustable structure. When the shock absorbing strength of the shock absorber needs to be reduced, the adjusting stud is rotated clockwise. Under the action of the screw sleeve, the adjusting stud will rotate and move downward, and will drive the hydraulic cylinder to move vertically downward inside the lifting sleeve, thereby reducing the shock absorbing stroke of the shock absorber. At the same time, when the shock absorbing strength of the shock absorber needs to be increased, the adjusting stud is rotated counterclockwise. The adjusting stud will drive the hydraulic cylinder to move vertically upward inside the lifting sleeve, thereby increasing the shock absorbing stroke of the shock absorber. This structure can adjust the shock absorbing strength of the shock absorber, which is convenient for adjusting the shock absorbing treatment of electric bicycles of different qualities and also improves the applicability of the shock absorber.

[0012] 2. In the present invention, the shock absorber of the electric bicycle is internally provided with a compound shock absorbing mechanism. When the vehicle bumps during driving, the plunger rod squeezes the hydraulic cylinder, which can perform the first step of buffering the impact force received by the electric bicycle. At the same time, when the first mounting plate arranged on the inner side of the fixed ring is subjected to the impact force, it will squeeze the limiting slide column distributed in a ring array. The shock absorbing spring on the limiting slide column can further buffer the impact force received by the vehicle. This compound shock absorbing structure can buffer the impact force received by the electric bicycle in layers, thereby improving the shock absorbing effect of the shock absorber.
