Abstract

The invention provides a prism device applied to a periscopic lens module and the periscopic lens module. The prism device comprises a bearing frame, a supporting reset component, a prism and a plurality of shape memory alloy wires, wherein the bearing frame comprises a base with a concave cavity and a supporting table arranged in the concave cavity; the shape memory alloy wires include a first shape memory alloy wire, a second shape memory alloy wire, a third shape memory alloy wire and a fourth shape memory alloy wire; and the first shape memory alloy wire and the second shape memory alloy wire are used for driving the supporting reset component to drive the prism to rotate around a first rotating central axis, the third shape memory alloy wire and the fourth shape memory alloy wire areused for driving the supporting reset component to drive the prism to rotate around a second rotating central axis, and the first rotating central axis is perpendicular to the second rotating centralaxis. The lens module is provided with the prism device. Through the scheme, the prism can rotate towards the two perpendicular central axes, stability is high, the structure is simple, and miniaturization is realized.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of imaging equipment, in particular to a prism device applied to a periscope lens module and a periscope lens module with the prism device. [0003] 【Background technique】 [0004] The periscope lens module is a lens module in which the optical zoom is completed inside the fuselage. A periscope lens module generally includes a lens device, a prism device and an image sensor. In the prior art periscope lens module, it is necessary to control the rotation of the prism of the prism device to achieve automatic anti-shake and improve the imaging quality. However, the structure of the existing prism rotation is relatively complicated, and it is difficult to realize the miniaturization of the prism device. [0005] Therefore, it is necessary to provide a new prism device applied to a periscope lens module to solve the above problems. [0006] 【Content of invention】 [0007] The object of the present invention is t...
