[0003] However, because the road surface is uneven during the actual driving process, electric bicycles are generally equipped with shock absorbers. However, when the existing electric bicycles are driving on continuously uneven roads, the shock absorbers cannot effectively reduce the vibration, causing people to be very bumpy during the riding process.
[0004] In order to solve the above problems, we propose a rear shock absorber connection structure for an electric bicycle. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-Figure 3A rear shock absorber connection structure of an electric bicycle comprises a rear seat cushion 1, the rear seat cushion 1 comprises a symmetrically arranged shock absorbing mechanism, the shock absorbing mechanism comprises a fixed plate 2 and a shock absorber 8, the fixed plate 2 is fixedly connected to the bottom of the rear seat cushion 1, the outer wall of the fixed plate 2 is fixedly connected with a fixed block 3, the bottom of the fixed block 3 is fixedly connected with two limiting rods 4, the outer wall of the fixed plate 2 is provided with a sliding groove, a movable block 7 is slidably connected in the sliding groove, the inner wall of the sliding groove is fixedly connected with a spring 5 fixedly connected to the top of the movable block 7, the movable block 7 is provided with two sliding holes, the two limiting rods 4 pass through the sliding holes and slide in contact with the movable block 7, the bottom of the movable block 7 is fixedly connected with a shock absorber 8, the bottom of the shock absorber 8 is fixedly connected with a connecting plate 9, the bottom of the connecting plate 9 is provided with a supporting block 11, the two limiting rods 4 are located at the left and right sides of the bottom of the fixed block 3 On the side, the diameter of the sliding hole is equal to the diameter of the limit rod 4, and damping fluid is smeared in the two sliding holes. When the spring 5 is reset for shock absorption, the damping fluid can effectively reduce the vibration amplitude generated by the spring 5 during movement, thereby ensuring the stability of the spring 5 during shock absorption. When the electric bicycle passes through a continuous uneven road section, the vibration will be transmitted to an upward force, causing the support block 11 to move upward, thereby causing the shock absorber 8 to work and complete the first step of shock absorption. When the shock absorber 8 is working, it will drive the movable block 7 to move vertically up and down along the limit rod 4 through the vibration amplitude. When the vibration energy is too large, the vibration amplitude of the shock absorber 8 will be too large, which will increase the vertical movement distance of the movable block 7. When the movable block 7 moves upward, the spring 5 will be in a compressed state, thereby performing a second shock absorption operation on the movable block 7 through the rebound force of the spring 5, thereby improving the shock absorption effect.
[0020] The support block 11 is threadedly connected to the connecting plate 9 by two fastening bolts 10, and the outer side sleeves of the two limit rods 4 are provided with buffer pads 6. The outer side wall of the support block 11 is rotatably connected with the rotating shaft 13, and the outer side wall of the rotating shaft 13 is fixedly connected with the wheel 12. The outer side wall fixed sleeve of the shock absorbing mechanism is provided with a protective cover 14. The buffer pad 6 is located at the top of the limit rod 4 and contacts with the fixed block 3. The top of the protective cover 14 contacts and is fixed to the bottom of the fixed block 3, and is detachable. The bottom of the protective cover 14 contacts and is fixed to the top of the support block 11, and is detachable. The buffer pad 6 is made of rubber material. The protective cover 14 can effectively protect the shock absorbing mechanism and extend the service life of the shock absorbing mechanism. When the vibration amplitude is too large, the movable block 7 moves upward too much and will contact the buffer pad 6. The rubber material of the buffer pad 6 is used to complete the third shock absorption, and it can also protect the movable block 7 and the fixed block 3 to avoid collision and affect riding.
[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
