Abstract

The invention discloses a voice coil motor with linear bearing guiding. The motor comprises an external stator of the voice coil motor, a rotor coil of the voice coil motor, a guiding circular shaft and a linear bearing. A central hole of the external motor of the voice coil motor is enlarged according to the structure and shape of a voice coil motor product, the cylindrical linear bearing is pressed into the central hole, the linear bearing and guiding circular shaft are fixed to the center of the coil of the matched voice coil motor rotor to play a center fixing effect, and the guiding circular shaft cooperates with the linear bearing to realize reciprocal movement of the rotor coil, and the problem of friction between the voice coil rotor coil and stator can be overcome.

Description

technical field [0001] The invention relates to the field of voice coil motors, more specifically, the invention is a voice coil motor with a linear bearing guide. Background technique [0002] At present, our voice coil motors all use square linear guide rails, which are installed outside the stator of the voice coil motor. The structure is relatively complicated and the volume is large, which cannot meet the requirements of the force of the voice coil motor and the compact structure. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a voice coil motor with linear bearing guidance, which lies in enlarging the center hole of the voice coil stator and pressing it into the linear bearing, and at the same time, at the center of the supporting voice coil motor mover coil The guide shaft is fixedly installed to realize the rotation of the mover coil of the voice coil motor and the repeated movement up and down, and re...
