Abstract

The invention provides an electromagnetic adjustable vibration damper, and belongs to the technical field of vibration dampers. The electromagnetic adjustable vibration damper comprises a cylinder body, a first piston device and a second piston device; the first piston device and the second piston device each comprises a piston head and a piston rod; one end of the cylinder body is provided with afirst through hole, and the other end of the cylinder body is provided with a second through hole; one end of the first piston device is internally provided with a first electromagnetic coil; one endof the second piston device is internally provided with a second electromagnetic coil, and the middle of the second piston device is sleeved with a spring; the interior of the first piston device andthe interior of the second piston device are both provided with adjusting systems for controlling the magnitude of currents of the first electromagnetic coil and the second electromagnetic coil; theadjusting systems are electrically connected with the first electromagnetic coil and the second electromagnetic coil; and vibration damper strength control is achieved, the elongation of the vibrationdamper is controllable, and the very good practicality is achieved.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to an electromagnetic adjustable shock absorber. Background technique [0002] In today's society, shock absorbers are used in more and more complex scenes, especially shock absorbers used on robots. Shock absorbers play an increasingly important role in people's lives, but the existing technology The shock absorber structure of the shock absorber system includes springs and hydraulic cylinders, which have the disadvantages of slow response and non-adjustable strength. Different shock absorbers need to be designed for each usage scenario, which seriously affects the manufacturing cost and the scope of promotion. [0003] After searching, it is found that some typical prior art, such as the patent application number 201610704410.3, discloses a shock absorber. When the first shaft tube rotates relative to the seat body and the abutting piece corresponds to the groove, the abut...
