Embodiment 1

[0050] Such as Figure 1-8 As shown, the present invention provides a voice coil motor that is easy to adjust, including a base 1 and a housing 2 that are fixedly connected to each other, and the base 1 and the housing 2 are fitted together to form the main body of a voice coil motor that is easy to adjust. The main body of the motor plays a good supporting effect and bearing effect; and the voice coil motor that is easy to adjust also includes a lens carrier 3 embedded between the base 1 and the housing 2, an upper elastic piece 5 located on the upper end surface of the lens carrier 3 and a lens carrier located on the upper surface of the lens carrier 3. The lower elastic sheet 4 on the lower end surface of the carrier 3, the coil 6 wound on the outer ring of the lens carrier 3 and the magnet 7 evenly distributed in the circumferential direction of the coil 6, the magnet 7 is in the shape of a trapezoidal column, and the shape of the magnet 7 is adapted to the shell 2 and the ...

Embodiment 2

[0062] Embodiment two is carried out on the basis of embodiment one.

[0063] The invention also provides an adjustment method of the voice coil motor which is convenient for adjustment;

[0064] S1, turn the adjustment screw 801 and drive the follower slide 802 to press down, so that the adjustment spring 803 is in a stretched state.

[0065] Wherein, adjusting the adjustment stud 801 makes the height position of the follower slide 802 change, and then the adjustment spring 803 is stretched, so that the elastic force formed between the adjustment spring 803 and the upper elastic piece 5 is increased, and then the lens carrier 3 is cut up and down magnetically. When the sense wire moves, it is less prone to irrecoverable deformation, thus prolonging the service life of the voice coil motor.

[0066] The working method of the voice coil motor is simple and fast, and the elastic adjustment of the upper elastic piece 5 is well realized, the service life of the upper elastic piec...

Abstract

The invention relates to a voice coil motor convenient to adjust, and a working method thereof. The voice coil motor comprises a pedestal and a shell which are fixedly connected with each other, a lens carrier embedded between the pedestal and the shell, a lower elastic sheet located on the lower end surface of the lens carrier, a coil wound on the outer ring of the lens carrier, and magnets uniformly distributed in the circumferential direction of the coil. The lens carrier is annular and is provided with an annular bottom connecting ring and four limiting blocks in the circumferential direction of an outer ring of the lens carrier, the four limiting blocks are arranged at intervals and form an upper limiting ring, the upper limiting ring and the bottom connecting ring are parallel to each other, and an adjusting part is arranged between the two limiting blocks; and the adjusting part is suitable for adjusting the pressing force of the upper elastic sheet. Through the arrangement of the adjusting part, the adjusting part is used for adjusting the distance between the follow-up sliding plate and the positioning plate, then the elastic force of the adjusting spring and the elastic force of the joint spring are changed, and the elastic force of the upper elastic piece is adjusted while a good damping feeling is provided for the upper elastic piece, so the overall service life is prolonged.
