Abstract

The invention relates to an optical-machine module and the lens moving buffer device that includes lens, actuator, the first magnetic component and the second magnetic component. The actuator supplies a thrust to drive the lens along optical axis direction. And the first magnetic component is set on the lens. The second magnetic component generates a magnetic reverse thrust along optical direction between the first magnetic component and the second magnetic component. When the actuator drives the lens, the second magnetic component supplies reverse thrust as the buffer power for lens. The non-contact magnetic component takes the place of contact flexible component to avoid the noise and decrease the installing complex. It could effectively save space and decrease volume of the optical-machine module.

Description

technical field [0001] The invention relates to an optical-mechanical module and its lens moving buffer device, in particular to an optical-mechanical module and its lens moving buffering device using magnetic force as the buffer force required for lens movement. Background technique [0002] In the optical-mechanical module of a general digital camera, the power required for moving the lens is mainly provided by an actuator. In order for the lens to move back and forth to focus the image on the sensor, a buffer force is usually required as the force for the lens to return. [0003] Please refer to figure 1 , which shows a schematic cross-sectional view of a traditional opto-mechanical module using a spring to generate a buffer force. In the optical-mechanical module 10, the lens 11 is pushed by the driving force Fd generated by the actuator 15 to move along the optical axis direction K, and at the same time, the buffer force Fb generated by the spring 12 is used as the re...
