Split-type lens carrier for voice coil motor

Abstract

The invention discloses a split-type lens carrier for a voice coil motor, the carrier comprises a thread base and a coil base, the thread base sleeves the inner wall of the coil base, the thread base is clamped in a thread base hole of the coil base through a matched connection of a clamp convex block and a clamp groove. According to the above way, the split-type lens carrier of the voice coil motor provided by the invention replaces a lens carrier with one-piece structure in the prior art; the thread base and the coil base have split-type structures, the thread base with different sizes can be randomly changed according to the size of the lens, the carrier is easy to detached, the cost is saved, the connection between the thread base and the coil base is firm, the twisting force for matching the voice coil motor and the lens is improved, so that the actual matching capacity of the twisting force is high, the stability of the lens carrier is high when the lens is mounted and applied, the whole structure is firm, and the service life is long.

Description

technical field [0001] The invention relates to the field of camera lens driving, in particular to a split lens carrier of a voice coil motor. Background technique [0002] A voice coil motor is a motor used in high-pixel miniature digital cameras with auto-focus function. Miniature digital cameras are not limited to applications such as mobile phones, computers, automobiles, security, digital cameras, tablet computers, and MP3 players, etc. The movement of the lens is usually performed by a motor as a driving device, which is commonly called lens drive in the industry. Devices and motors generally use voice coil motors (English name: Voice Coil Motor, VCM for short), and the principle of voice coil motor driving lens movement comes from speakers. [0003] With the advancement of technology, the structure of miniature digital cameras is becoming smaller and smaller, and the requirements for voice coil motors are getting higher and higher, especially the cameras used in smar...

AI Technical Summary

Problems solved by technology

In the prior art, the lens carrier of the voice coil motor is an integrated structure. When installing lenses of different sizes, it is necessary to use different size lens carriers. At the same time, the matching torque of the voice coil motor and the lens is relatively low. To match the lens, a new opening is required. Mold-tooth bar, the lens is installed through the tooth bar, the use is not flexible, resulting in a great degree of waste
