Magnetic shock-absorption device

Abstract

The invention discloses a magnetic shock-absorption device which comprises a cylinder base and a magnetic group, wherein the magnetic group comprises a plurality of magnetic units; each magnetic unit comprises a magnet and a protective sleeve for wrapping the magnet; holes are formed in two surfaces of each protective sleeve respectively; and the magnetic units are arranged in the cylinder base in a serial manner, so that magnetic repulsive force is generated between opposite surfaces of every two adjacent magnetic units. Accordingly, damping force is generated by utilizing the magnetic repulsive force generated by the magnetic units in the magnetic group, and the shock-absorption effect is realized.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a magnetic shock absorber. Background technique [0002] Shock absorbers are used in a wide range of applications, such as cars, locomotives or chairs, etc., shock absorbers are installed in cars or locomotives, which can slow down the vibration caused by cars or locomotives running on uneven roads, and avoid passengers and drivers. The bumps in the car or on the locomotive are beneficial to the stability and comfort of the passengers and drivers; in addition, if used on the support seat of the seat, it can slow down the impact force that the user can generate when sitting on the seat, and avoid The user's spine is injured by sitting on the seat quickly, and the comfort of the seat can also be increased, so that the user is less likely to feel uncomfortable after sitting for a long time. At the same time, the good shock-absorbing design can absorb the fine vibration , to achieve the function...

Problems solved by technology

[0004] However, the existing shock absorbers still have the following disadvantages. First, the material area of ​​the spring is unevenly stressed, and after it cooperates with the piston and the working fluid; The active force provides different damping force requirements, so the effect of the shock absorber is often not good in actual use; thirdly, the structure of the existing shock absorber is complex and bulky, so it is easy to cause damage to the manufacturing process and materials. The cost is wasted and the assembly is not easy, which leads to the consumption of assembly man-hours and costs; the fourth point, if the working fluid is liquid, the recovery speed of the piston is slow, so it cannot be sensitive to different compression depths and different sizes of external forces. Relative reaction; the fifth point, if the working fluid is gas, because the compression ratio is nonlinear, when the external force reaches a certain level, the air is not easy to be compressed by the piston, but a reverse force is generated instead, so that the connection The connecting rod on the piston is damaged; and it needs to be improved urgently
