Technical Field
[0001] The utility model relates to the technical field of shock absorption, in particular to a rear shock absorption for a scooter. Background Art
[0002] In modern life, as people's environmental awareness increases, more and more people choose green travel. In order to meet users' short-distance travel needs, various scooters have emerged. Scooters are suitable for use by people of all ages because of their moderate speed, easy to learn and easy to operate. They are especially popular among teenagers. In daily use, scooters are prone to bumps when passing through uneven roads, affecting safe driving and comfort. More and more scooter models have added shock absorbers.
[0003] In the prior art, the shock absorbing device of a scooter usually uses a combination of a spring and a hydraulic shock absorber to absorb the shock of the scooter. However, the hydraulic shock absorber may leak after a long period of use, resulting in a weakened shock absorbing effect of the hydraulic shock absorber. In addition, since the shock absorber is relatively fragile, it will deform or crack when hit, resulting in the shock absorber being scrapped. The existing rear shock absorber of a scooter has no protective facilities. Therefore, a rear shock absorber of a scooter is proposed to address the above problems. Utility Model Content

[0009] Preferably, the first magnet and the second magnet are both cylindrical in shape, the first magnet and the second magnet have the same outer diameter, and the inner diameter of the shock absorbing shell is larger than the outer diameter of the first magnet.
[0010] Preferably, the connection between the limit rod and the second magnet is a sliding connection, the top of the shock-absorbing spring is fixedly connected to the bottom of the second magnet, and the bottom of the shock-absorbing spring is fixedly connected to the top of the first magnet, the number of the limit rods and shock-absorbing springs is six each, and the number of the slider and the slide groove is two each.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. In the utility model, the shock-absorbing shell, the first magnet, the second magnet, the limit rod, the shock-absorbing spring, the slider, the slide groove, the first mounting column and the second mounting column are provided, so that the shock-absorbing effect of the shock absorber is greatly improved, and its service life is increased. First, the shock absorber is installed on the scooter, and the first mounting column is installed on the skateboard using a tool, and the second mounting column is installed on the pulley, and the scooter can be used normally. When encountering a bumpy road section, the first magnet is lowered due to the inertia of the skateboard, the limit rod passes through the first magnet, and the slider slides inside the slide groove. At this time, due to the repulsive force of the first magnet and the second magnet, the shock-absorbing spring is compressed and reset, so that the vibration of the scooter is greatly reduced, which increases the use experience of passengers;
[0013] 2. In the utility model, by providing fixing bolts, protective shells, mounting grooves, rotating shafts, fixing blocks, round holes and nuts, protection measures are added to the outer side of the shock-absorbing shell, so that the impact resistance of the shock-absorbing shell is improved. The protective shell is installed on the outer side of the shock-absorbing shell before use. First, the end of the protective shell with the mounting groove is placed vertically upwards, and the outer side of the shock-absorbing shell is sleeved from the bottom end of the shock-absorbing shell upwards, so that the fixing bolts enter the inner side of the mounting grooves. Then, the fixing blocks are turned over, and the rotating shaft is rotated until the fixing bolts enter the inner side of the round holes. The installation of the protective shell is completed by tightening the nuts. When impacted, the protective shell replaces the shock-absorbing shell to bear most of the impact force, so that the shock-absorbing shell has stronger impact resistance.
