Shock absorber capable of improving generating efficiency by using suspension magnets under shock absorption working condition

Abstract

The invention relates to a shock absorber capable of improving generating efficiency by using suspension magnets under a shock absorption working condition, which belongs to the shock absorber which not only has damping comfort but also can recover consumed mechanical energy into electric energy at high proportion. At least one suspension magnet is arranged in the tube body of the shock absorber;the magnetic poles of the suspension permanent magnets are opposite to the magnetic poles of a positioning permanent magnet and a piston permanent magnet; the magnetic poles of the suspension permanent magnets are opposite; at least one generating coil is arranged in the nonmagnetic material inner tube of the tube body and an interlayer space of which the outer layer is a rigid bearing tube; the magnetic pole face of each suspension permanent magnet is provided with a closed loop coil for generating a damping action; and the annular faces of all turns of coils of the generating coil and the closed loop coil are vertical to the centre line of the tube body. The shock absorber capable of improving the generating efficiency by using the suspension magnets under the shock absorption working condition has the advantages that the structure is simple, the cross section is small, the weight is light, the consumed mechanical energy can be recovered into the electric energy at high proportion; and the damping property is good.

Description

technical field [0001] The present invention belongs to the shock absorber which can partially recycle the consumed mechanical energy into electric energy when the shock absorber is working in reciprocating motion, especially the shock absorber which not only has damping comfort but also can recover the consumed mechanical energy into electric energy in a high proportion device. Background technique [0002] Now use the magnetic force of the magnet as the elastic force of the shock absorber. A fixed magnet is fixed at the bottom of the shock absorber, and a moving magnet that moves synchronously with the piston is fixed on the piston. The magnetic poles of these two strong magnets are the same. The relative repulsion force of the magnetic poles acts as the elastic force of the shock absorber. Because the magnetic force of the permanent magnet is generally small, just increase the volume of the stationary magnet and the moving magnet, and increase the area of ​​the opposing ...

AI Technical Summary

Problems solved by technology

The disadvantage is that the weight of the shock absorber is too large, the cross section of the shock absorber is also too large, it consumes a lot of materials, the cost is high and it lacks practicality.

If a group of NdFeB magnets with a diameter of 3.0 cm are used as the elastic part of the shock absorber of an electric bicycle, the stroke of the shock absorber is only 2.0-3.0 cm; if a group of ferrite magnets with a diameter of 10.0 cm are used as The elastic part of the shock absorber of the electric bicycle, the stroke of the shock absorber is only 2.0-4.0 cm, not only the volume is large, the weight is heavy, the cost is high, the stroke is also too short, there is no flexibility of damping

[0003] In order to overcome the lack of magnetic force of permanent magnets, some people use electromagnets as elastic parts of shock absorbers to increase the magnetic force. The shock absorption effect of the shock absorber changes with the electric energy of the battery, that is, the shock absorption effect of the shock absorber is unstable

In order to prevent the battery from failing to supply power, an additional spring is required as a spare part. This kind of shock absorber has a complicated structure and poor stability.
