AI Technical Summary

Technical Problem

In existing flat micro motors, the flexible PCB board lacks external fixation and protection, making it prone to detachment when pulled, causing short circuits or localized overheating and affecting the stability of use.

Method used

It adopts a combination structure of protective shell, fixing plate, fixing rubber pad, extrusion plate, moving rubber plate, bolts and guide unit to clamp and fix flexible PCB board, and absorbs vibration through annular hollow arc strip and silicone strip to improve protection performance and noise reduction effect.

Benefits of technology

It effectively prevents flexible PCB boards from falling off, improves the waterproof protection performance of the connection points, reduces vibration and noise, and enhances the stability and quietness of the motor.
