PRISM DEVICE APPLIED TO PERISCOPIC LENS MODULE AND PERISCOPIC LENS MODULE

WIPO Patent Application WO/2020/243863

A1

A prism device applied to a periscopic lens module and a periscopic lens module. The prism device (10) comprises a bearing frame (11), a supporting and resetting assembly (12), a prism (13) and several shape memory alloy wires (14). The bearing frame (11) comprises a base body (111) having a recessed cavity (1111) and a supporting platform (112) provided within the recessed cavity (1111). The shape memory alloy wires (14) include a first shape memory alloy wire (141), a second shape memory alloy wire (142), a third shape memory alloy wire (143) and a fourth shape memory alloy wire (144), the first shape memory alloy wire (141) and the second shape memory alloy wire (142) are used to drive the supporting and resetting assembly (12) to drive the prism (13) to rotate about a first rotation center axis, the third shape memory alloy wire (143) and the fourth shape memory alloy wire (144) are used to drive the supporting and resetting assembly (12) to drive the prism (13) to rotate about a second rotation center axis, and the first rotation center axis is perpendicular to the second rotation center axis. The lens module and the prism device enable the prism to rotate towards two center axes which are perpendicular to each other, having high stability and a simple structure, achieving miniaturization.
