Embodiment 1

[0056] Such as Figure 1-10As shown, in order to realize the function of adjustable elastic force, the present invention provides a voice coil motor with adjustable elastic force. The voice coil motor with adjustable elastic force includes a base 100 and a housing 200 that are fixedly connected to each other, and the base 100 and the housing 200 The body of the voice coil motor with adjustable elastic force is fitted together to form the main body of the voice coil motor with adjustable elastic force, which plays the role of carrying and supporting other devices inside the voice coil motor with adjustable elastic force, and has a good supporting effect and bearing effect; The voice coil motor also includes a lens carrier 300 embedded between the base 100 and the housing 200 , an upper elastic piece 400 located on the upper end surface of the lens carrier 300 and a lower elastic piece 500 located on the lower end surface of the lens carrier 300 , wound around the outer ring of t...

Embodiment 2

[0072] Embodiment two is carried out on the basis of embodiment one.

[0073] S1, relative to the base 100 , turn the lower damping column 731 to adjust its height relative to the base 100 .

[0074] Wherein, adjusting the lower damping column 731 makes the height of the base 100 change, and then compresses the lower damping spring 721 to increase the elastic force formed between the lower damping spring 721 and the lower elastic piece 500 .

[0075] The working method of the voice coil motor is simple and fast, and the elastic adjustment of the lower elastic piece 500 is well realized, the service life of the lower elastic piece 500 is prolonged, the cost is reduced and the economic benefit is improved.

Abstract

The invention relates to a voice coil motor with adjustable elastic force and an adjustment method thereof. The voice coil motor includes a base and a casing fixedly connected to each other, a lens carrier embedded between the base and the casing, and an upper elastic piece located on the upper end surface of the lens carrier. And the lower shrapnel located on the lower end surface of the lens carrier, the coil wound on the outer ring of the lens carrier and the magnets evenly distributed in the circumferential direction of the coil, the surface of the base is loaded with multiple buffer components, each buffer component is adapted to a magnet, and the magnet presses The buffer assembly is combined, and the lower elastic piece is clamped in the buffer assembly, wherein the buffer assembly is suitable for adjusting the pressing force of the upper and lower end surfaces of the lower elastic piece. The present invention realizes the effect of vertical adjustment of the voice coil motor through the base, the shell, the lens carrier, the upper shrapnel, the lower shrapnel and the magnet that are mutually adapted; through the setting of the buffer assembly, the buffer assembly is adjusted to adjust the pressure on the upper and lower surfaces of the lower shrapnel , to provide a good damping feeling for the lower shrapnel while adjusting the deformation and elasticity of the lower shrapnel, thereby prolonging the overall service life.
