Description
Technical field
Patent of the present invention is related to a kind of drive motor, and in particular to one kind is used for video camera, camera or with work(of taking pictures
Lens drive motor on the electronic equipment of energy.
Background technology
At present, because voice coil motor has the advantages that small volume, power consumption are few and cheap, therefore voice coil motor is
It is widely used in as actuator in electronic product, especially in camera module（Such as mobile phone camera）Actuator adopt substantially
Use voice coil motor.Traditional voice coil motor generally includes lens carrier, housing, upper shell fragment, lower shell fragment, coil and magnet, typically
It is to fix magnet in the housing, coil is connected with lens carrier, is moved by coil come drive lens carrier, due to coil meeting
Stress moves, and the wire that coil is drawn can also be affected by coil, so that the wire drawn is easily damaged, the position of lens carrier
Put by upper shell fragment and lower shell fragment to limit, due to the elasticity of upper shell fragment and lower shell fragment, coil supporter can not only be in the axial direction
Upper movement, it can also be moved in the plane perpendicular to axial direction.So drive camera lens module at work, it is likely that by
Elastic deformation occurs in the plane perpendicular to axial direction in shell fragment, and the camera lens for be contained in sleeve is perpendicular to optical axis
Certain skew is produced in plane, so that optical axis can not focus, so as to influence the quality of shooting.
The content of the invention
For deficiency of the prior art, the invention provides a kind of lens drive motor.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：

The outside of lower shell fragment is fixedly connected with lower housing portion, and the inner side of the lower shell fragment is connected with lens carrier bottom edge, it is described on
Yoke is provided between shell fragment and lower shell fragment, the inner side of the yoke is provided with fixed coil, and the permanent magnet is fixed on the lens
The outside of carrier.
Preferably, the top of the shell is provided with upper holder, the bottom of the shell is provided with lower fixed frame, it is described on
The front end of fixed mount is provided with lead one, and the front end of the lower fixed frame is provided with lead two, and the top of the lens carrier is set
There is blind hole one, the bottom of the lens carrier is provided with blind hole two, and the lower end of the lead one is located in the blind hole one, described
The upper end of lead two is located in the blind hole two.
Preferably, the top and bottom of the yoke are equipped with kink.
Preferably, the fixed coil is between two kinks.
Preferably, the bottom of the housing is additionally provided with base.
Preferably, the bottom of the base is provided with the installation portion to stretch out.
The beneficial effects of the invention are as follows：
Coil is arranged to fixed by the present invention, and caused magnetic field, which allows, after being powered by fixed coil is fixed on lens carrier
Upper magnet stress drives lens carrier motion, and coil extraction wire is affected so as to avoid coil movement, extends use
Life-span.By setting lead one and lead two so that lens carrier is not sent out in the plane perpendicular to shell axial direction
Raw movement, so that camera lens will not produce skew in the plane perpendicular to optical axis, improves the quality of shooting.
