Problems solved by technology

[0002] In the prior art, the general vibration damping springs are directly connected between the support bracket and the vibrating piece bracket in the electromechanical product. When the vibration damping spring is an extension spring, although the use of multiple vibration damping springs can reduce the The shaking caused by the vibration, but the S-shaped bending lateral distortion of the vibration damping spring in the axial direction caused by the shaking of the vibrating member is still unavoidable. Causes vibration of the entire electromechanical product, reducing the effect of the vibration damping spring

At the same time, when multiple damping springs are used, due to machining and installation reasons, sometimes it is difficult to make all the damping springs positioned accurately. It is not only affected by the vertical gravity, but also by the torsion of the S-shaped twist generated in the horizontal direction, which makes the vibrating part in an unbalanced state when vibrating and reduces the vibration damping effect.

In addition, the concentricity deviation of the damping spring itself will also affect the damping effect

[0003] In the same way, when the vibration damping spring is a compression spring, it will also appear in a phenomenon similar to the above, which will affect the vibration damping effect.
