Description
Technical field
The present invention relates to voice coil motor fields, more specifically, the present invention is a kind of voice coil electricity with linear bearing guiding
Machine.
Background technique
Our voice coil motors are all to be mounted on the stator exterior of voice coil motor, structure using rectangular linear guide at present
More complicated, volume is big, is unable to satisfy while meet to voice coil motor power, also to meet compact-sized demand.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of voice coil motor with linear bearing guiding, it is to increase
The centre bore of voice coil stator, and it is pressed into linear bearing, while being fixedly mounted and leading at matched voice coil motor mover coil center
It to circular shaft, realizes the rotation of voice coil motor mover coil and moves repeatedly up and down, and reduce voice coil motor mover coil and sound
Enclose the friction between motor stator.
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of sound with linear bearing guiding
Motor, including voice coil motor external stator are enclosed, voice coil motor mover coil is oriented to circular shaft and linear bearing, and the voice coil motor is fixed
Circular through hole is offered at sub- central axes, and the counterbore greater than through-hole diameter is offered above the through-hole, fixed peace in the counterbore
Equipped with circular linear bearing, voice coil motor mover fixing groove is offered in the voice coil motor stator, the voice coil mover fixing groove
It is inside slidably fitted with voice coil motor mover coil, it is fixed logical that guiding is offered at the voice coil motor mover coil central axes upper end
Hole is fixedly installed with guiding circular shaft in the guiding fixed hole, which passes through guiding fixed hole and set with linear bearing
Some central through holes and voice coil motor stator are slidably connected equipped with circular through hole.
Further, the voice coil motor mover that the voice coil motor mover coil ring set insertion voice coil motor stator is equipped with is solid
Determine in slot.
Further, the voice coil motor mover coil can be done along voice coil motor stator central axes rotation and up and down it is past
Multiple movement, the guiding circular shaft along the rotation of voice coil motor stator and pump to voice coil motor mover and play guiding calmly
The effect of position.
The present invention provides it is a kind of with linear bearing guiding voice coil motor, have it is following the utility model has the advantages that
Overall volume is reduced, and it is reciprocating along voice coil motor stator central axes to realize voice coil motor mover coil
While, it largely avoided the friction problem between voice coil motor mover coil and voice coil motor stator.
Detailed description of the invention
Fig. 1 is perspective view of the invention；
Fig. 2 is main view cut away view of the invention.
