Technical Field

The invention relates to the field of shock absorbers, in particular to an electromagnetic shock absorber with light-operated adjustment and a control system thereof.

Background

When the shock absorber works, a damping effect is generated to suppress the change speed and the change amplitude of the shock absorbing object during shaking, when the shock absorber with small damping is selected, the damping effect on the reciprocating motion of the shock absorbing object is small, and when the shock absorber with large damping is selected, the damping effect on the reciprocating motion of the shock absorbing object is large.

The inventor discovers that in the process of implementing the embodiment of the invention:

for the application of a common single shock absorber, the damping range of the shock absorber is fixed, so that the adaptive working condition range is relatively narrow; if the single-body shock absorbers with different damping ranges are selected for use together, the structure is complex, the size is large, and the application cost is high. Therefore, currently there is a lack of such a product in the field of shock absorbers: the damping selection range is large, the damping device can automatically adapt to working conditions, the structure is simple and compact, and particularly when the damping device is used in a wide working condition range, the operation cost is relatively low.
