Title:
MOTOR FOR DRIVING LIQUID STATE CAMERA LENS, LENS ASSEMBLY, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/273341
Kind Code:
A1
Abstract:
A motor for driving a liquid state camera lens, a lens assembly, and a terminal device. The motor comprises at least one sub-motor (10). The sub-motor (10) can be independently controlled. The sub-motor (10) comprises: a stationary member portion; a movable member portion capable of moving relative to the stationary member portion along an optical axis direction of a liquid state camera lens, the stationary member portion comprising a stationary guide member (101), the movable member portion comprising a movable guide member (102), a connecting arm (104), and a plurality of guide balls (103), the stationary guide member (101) being provided opposite to the movable guide member (102), the plurality of guide balls (103) being provided between the stationary guide member (101) and the movable guide member (102), the connecting arm (104) being provided at the end of the movable guide member (102) facing the liquid state camera lens (20), and the movable guide member (102) driving the rigid connecting arm (104) to press the liquid state camera lens (20) when receiving a force in the optical axis direction; and a driving circuit portion for controlling displacement of the movable member portion in the optical axis direction. The stationary guide member (101), the movable guide member (102), and the guide balls (103) work in concert, thereby reducing the loss of a driving force during a movement process of the movable guide member (102) and ensuring the accuracy of autofocusing and optical image stabilization.
