Abstract

The invention provides a lens driving motor, a camera and a mobile terminal. The lens driving motor comprises a shell, an upper spring, a driving magnet, a driving coil, a lens supporting body and a lower cover assembly. The shell is arranged on the lower cover assembly to form an accommodating space between the shell and the lower cover assembly; the driving magnet, the driving coil and the lenssupporting body are all located in the accommodating space, the driving coil is arranged on the lens supporting body, the driving magnet is arranged corresponding to the driving coil, the upper springis arranged between the shell and the lens supporting body. The upper spring comprises an outer ring structure connected with the shell, an inner ring structure connected with the lens supporting body, and a middle structure through which the outer ring structure and the inner ring structure are connected. A plurality of protruding parts are arranged on the middle structure, and at least two protruding parts extend in the direction close to each other to form an oiling gap. The lens driving motor solves the problem of poor use performance of the lens driving motor in the prior art.

Description

Technical field [0001] The present invention relates to the technical field of cameras, in particular to a lens drive motor, a camera and a mobile terminal. Background technique [0002] The main principle of the lens drive motor of the traditional camera module is to control the stretching position of the VCM spring sheet by changing the DC current of the coil in the motor in a permanent magnetic field and converting the current into mechanical force to drive the lens to move up and down. The function of lens focusing can achieve the purpose of moving the entire lens in a small distance, changing the focal length, and achieving a clear image. [0003] In recent years, the closed loop motor (Close Loop Motor) that has appeared in the market as a new technology has formed a closed loop system with focus position feedback function after the addition of the Hall chip, which has improved the focus speed and focus accuracy to a certain extent. However, as with other types of motors, it...
