Description
Technical field
The present invention relates to a kind of voice coil motor.
Background technology
Voice coil motor is accurately widely used in electronic product due to small volume, little power consumption and moving displacement
In actuating system.Voice coil motor mainly include moving parts, fixation kit, be arranged on moving parts and
Coil between fixation kit and Magnet.Moving parts can be contacted with fixation kit in non-focusing state
And holding position fixes, the work reaching focusing can be moved under electromagnetic action with respect to fixation kit again
With.
At present, in order that voice coil motor is in non-focusing state, moving parts are contacted simultaneously with fixation kit
And certain impact can be born and holding position is constant, generally in the prominent structure of moving parts setting, dash forward
Go out structure to contact with fixation kit, and in contact, be mutually adjacent to by external force effect.This external force
Can be by arranging shell fragment in voice coil motor, moving parts make shell fragment occur predeformation to produce, and also may be used
With by using magnetic material at the place of contacting with each other of described moving parts and described fixation kit, by magnetic
Power attracts one another and produces.The free end of prominent structure of the prior art is cylindricality, with fixation kit
The area of contact surface is larger.
Voice coil motor after assembling, drying to be carried out.However, prominent structure and fixation kit
Contact area not only results in greatly and is not easy to remove original spot and easily carry pollutant secretly from cleanout fluid,
In addition can lengthen affects drying effect drying time.It is dried not exclusively and pollutant incidentally can cause fixing group
Part easily sticks together and affects the actuating performance of voice coil motor with fixation kit.
Content of the invention
In view of the above is it is necessary to provide one kind can improve clean and degree of drying, guarantee actuating performance
Good voice coil motor.
A kind of voice coil motor, including a base, a shell, a fixation kit and moving parts.Described
Base includes a first surface, and described shell is arranged on described base.It is empty that described shell includes a collecting
Between, described fixation kit is housed in described receiving space and is carried on described first surface.Described solid
Determine assembly and include a fixed mount, described moving parts are arranged in described fixed mount.Described moving parts bag
Include a movable accommodating cylinder, described movable accommodating cylinder is provided through the accommodating hole of described movable accommodating cylinder.Described activity
Fitted tube also includes a bottom surface just to described first surface, and described bottom surface arranges at least two projections.Described
Projection and described base contacts, described projection include one away from described bottom surface end face, described end face by
Between be extended with two inclined-planes to two ends.
With respect to prior art, by arranging inclined-plane on the projection of described movable accommodating cylinder, because inclined-plane subtracts
Lack the area of projection and the contact surface of base, during being carried out being dried, less area holds
Easy to clean, be difficult to cause the attachment of pollutant, and drying time can be reduced it is ensured that drying effect,
And preventive activities fitted tube can stick together with base and affect the overall actuating performance of voice coil motor.
