Problems solved by technology
A periscope lens module generally includes a lens device, a prism device, and an image sensor. In the prior art periscope lens module, the optical image stabilization (OIS: optical image stabilization) of the prism device is mainly driven by an electromagnetic drive to rotate the prism. In order to achieve anti-shake compensation, that is, to adjust the angle of the prism through coils and magnets, this adjustment structure is expensive and not suitable for mass production

The invention provides a periscopic type lens module and a prism device applied to the same. The prism device applied to the periscopic type lens module comprises a carrying frame, a supporting and resetting assembly which can be rotationally arranged on the carrying frame, a prism which is arranged on the supporting and resetting assembly to rotate along with the supporting and resetting assembly, and a plurality of shape memory alloy wires which are connected between the carrying frame and the supporting and resetting assembly so as to drive the supporting and resetting assembly and the prism to rotate relative to the carrying frame; the supporting and resetting assembly comprises a shape memory alloy wire supporting frame which is rotatably connected with the carrying frame and an elastic supporting member which is arranged between the shape memory alloy wire supporting frame and the prism and is connected with the carrying frame; the prism is arranged on the elastic supporting member; and each shape memory alloy wire is arranged between the carrying frame and the shape memory alloy wire supporting frame. According to the periscopic type lens module and the prism device applied to the same of the invention, the shape memory alloy wires are used to drive the supporting and resetting assembly to rotate relative to the carrying frame, so that the prism can automatically correct an angle; the shape memory alloy wires are adopted to replace electromagnetic type driving, so that cost is reduced.
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, the optical image stabilization (OIS: optical image stabilization) of the prism device is mainly driven by an electromagnetic drive to rotate the prism. In order to achieve anti-shake compensation, that is, to adjust the angle of the prism through coils and magnets, this adjustment structure is expensive and not suitable for mass production. [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 inventi...
