Abstract

The invention provides a prism device and a periscope lens module applied to the periscope lens module. The prism device includes a carrier frame, a supporting reset assembly, a prism and several shape memory alloy wires. The carrier frame includes a seat body with a cavity and a support platform arranged in the cavity. The shape memory alloy wire includes a first shape memory alloy wire, The second shape-memory alloy wire, the third shape-memory alloy wire, the fourth shape-memory alloy wire, the first shape-memory alloy wire and the second shape-memory alloy wire are used to drive the supporting reset assembly to drive the prism to rotate around the first rotation center axis, The third shape memory alloy wire and the fourth shape memory alloy wire are used to drive the support reset assembly to drive the prism to rotate around the second central axis of rotation, and the first central axis of rotation is perpendicular to the second central axis of rotation. The lens module adopts the above-mentioned prism device. The solution of the invention can make the prism rotate towards two vertical central axes, has high stability, simple structure and realizes miniaturization.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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. [0003] Therefore, it is necessary to provide a new prism device applied to a periscope lens module to solve the above problems. 【Content of invention】 [0004] The object of the present invention is to provide a prism devic...
