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

Abstract

The present invention provides a prism device applied to a periscope lens module and a periscope lens module. The prism device applied to a periscope lens module includes a bearing frame, a supporting reset assembly rotatably mounted on the bearing frame, The prism installed on the support reset assembly to rotate with the support reset assembly and several shape memory alloy wires connected between the carrier and the support reset assembly to drive the support reset assembly and the prism to rotate relative to the carrier, the carrier includes a horizontal support plate, a vertical To the support plate and the two side plates, the vertical support plate is bent and extended upward from the horizontal support plate, and the shape memory alloy wires are respectively connected to the support reset assembly and the bearing frame from the two side plates to drive the support reset assembly to drive the prism around the first The rotation center shaft rotates and connects the support reset assembly and the bearing frame from the horizontal support plate and the vertical support plate respectively to drive the support reset assembly to drive the prism to rotate around the second rotation center axis. The invention adopts the shape memory alloy wire instead of the electromagnetic drive to reduce the cost.

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, 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. [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 objec...
