Title:
CAMERA MODULE AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/092858
Kind Code:
A1
Abstract:
A camera module, wherein a circuit board may slide under the action of a driving force, thereby driving a photosensitive chip to be displaced relative to a lens assembly so as to compensate for the optical axis offset of the lens assembly that is caused by vibration, thus implementing optical anti-shaking. The circuit board is supported by multiple balls and has better stability. In addition, since the circuit board is in point contact with the balls, the balls will roll quickly under the action of a friction force when the circuit board slides. Therefore, the friction force received by the circuit board during sliding is relatively small, therefore response is rapid, sensitivity is higher, and energy consumption is lower. In addition, although the balls roll following the circuit board, the plane defined by the balls remains unchanged, and therefore flatness is better when the circuit board slides. Hence, the described camera module has relatively high reliability while optical anti-shaking is implemented.
