Magnetic flux leakage prevention voice coil motor for mobile phone camera

Abstract

The invention discloses a magnetic flux leakage prevention voice coil motor for a mobile phone camera. The magnetic flux leakage prevention voice coil motor for the mobile phone camera comprises a mounting plate, a propelling groove and a voice coil motor body, and a plurality of chutes pointing to the center of the mounting plate are formed in the mounting plate; the propelling groove is fixed inthe center of the mounting plate; a T-shaped connecting rod is fixed at the bottom of the voice coil motor body; a plurality of U-shaped grooves are fixed to the side faces of the periphery of the voice coil motor; and sliding blocks are arranged in the chutes in a sliding mode, the sliding blocks are fixedly connected with the inner walls of the chutes through a buffer spring, a buffer rod is rotatably connected to the sliding blocks, a T-shaped sliding block is rotatably connected to the other end of the buffer rod, the T-shaped sliding block is slidably connected with the U-shaped groove,the propelling groove is sleeved with a wedging groove, and a U-shaped connecting groove matched with the T-shaped connecting rod is formed in the top of the wedging groove. The voice coil motor is convenient to install and has a good buffer effect, and the position of the motor can be adjusted, so that the propelling distance of the motor to the camera is increased.

Description

technical field [0001] The invention discloses an anti-leakage magnetic voice coil motor used for a mobile phone camera, belonging to the technical field of voice coil motor equipment. Background technique [0002] The mobile phone camera is equipped with an anti-leakage magnetic voice coil motor. The motor can provide a driving force for the lens in the camera to change the focus of the camera. Usually, this kind of motor will be directly welded and fixed at the corresponding position for stability. This kind of motor is small in size, which makes it inconvenient to repair and replace; this kind of motor will generate vibration force during use, and the connection will become loose after a long time, which will affect normal use. The existing fixing method of voice coil motor The position of the motor cannot be adjusted so that the lens cannot be further adjusted within the maximum working range, thereby increasing its use range.
