Abstract
Provided are a prism apparatus applied to a periscope lens module and a periscope lens module. The prism apparatus includes a bearing frame, a supporting member, a prism installed, shape memory alloy wires connected between the supporting member and the bearing frame and configured to drive the supporting member to rotate with respect to the bearing frame, and a restoring device connected between the supporting member and the bearing frame and configured to restore the supporting member. In the present invention, the shape memory alloy wires are used to drive the supporting member and the prism, such that the prism can automatically correct the angle, thereby improving the imaging quality. Moreover, the original electromagnetic drive is replaced with the shape memory alloy wires, which reduces a manufacturing cost of the prism apparatus applied to the periscope lens module, thereby achieving a mass production of the periscope lens module.
