Description

Technical Field

[0002] Magnetic damping is different from previous dampers that rely on materials such as silicone and frosted sheets to increase the friction resistance between metal, plastic, template and other plates and rods. Instead, it relies on a winding coil that can be connected to wires to generate magnetic force, which can quickly adjust the speed of sliding and landing of objects and can accurately control the size of resistance.

[0003] In the past, magnetic damping only relied on bolts to connect the positive and negative wiring harnesses with the damping body. As the use time increased, the metal wires often twisted, tangled, or even broke, which would cause troubles in subsequent disassembly and connection, and would also cause problems in the control of the coil's magnetic field.

[0004] Now, a new type of magnetic damping is proposed to solve the above problems. Utility Model Content
