Centering reset device and camera motor

Abstract

The invention relates to a centering reset device and a camera motor. The centering reset device comprises a bearing platform and a reset piece; the reset piece comprises a steel ball and a magnet, the steel ball is connected with the bearing platform and abuts against the magnet, and the bearing platform can drive the steel ball to horizontally move along the magnet when moving. When the camera motor applies lateral force to the bearing platform, the bearing platform can drive the steel ball to horizontally move on the magnet at the same time, after the lateral force is cancelled, the steel ball can be automatically reset to the initial position due to the attraction force between the steel ball and the magnet; compared with a transmission structure of a spring and a suspension wire, the installation process difficulty of the reset device is reduced, the magnet and the steel ball are matched to achieve an automatic centering function, and stable automatic reset can be achieved; and the steel ball and the magnet are rigid parts, so that the steel ball and the magnet are not easy to deform, break and the like in the use process.

Description

technical field [0001] The invention relates to the technical field of camera motors, in particular to a centering reset device and a camera motor. Background technique [0002] The camera motor is equipped with a movable part to achieve anti-shake of the lens. In the prior art, springs or suspension wires are usually used to suspend the movable part and realize horizontal movement and self-resetting. However, springs or suspension wires are relatively fine and fragile. , the assembly process of the suspension wire and the spring assembly is more complicated, and its reliability is low. During use, the spring or suspension wire is likely to be deformed or broken, which will affect the anti-shake effect of the camera motor. Contents of the invention [0003] In view of this, the present invention provides a centering reset device and a camera motor to solve the above technical problems. [0004] The object of the present invention is achieved through the following technica...
