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-restoring assembly rotatably mounted on the bearing frame; a prism rotatable with the supporting-restoring assembly; and shape memory alloy wires configured to drive the supporting-restoring assembly and the prism to rotate with respect to the bearing frame. The supporting-restoring assembly includes a shape memory alloy wire-supporting frame rotatably connected to the bearing frame, and an elastic support member elastically connected to the bearing frame. The prism is mounted on the elastic support member. The shape memory alloy wires are connected between the bearing frame and the shape memory alloy wire-supporting frame. In the present invention, the shape memory alloy wires replace the electromagnetic drive and are used to drive the supporting-restoring assembly to rotate relative to the bearing frame, and the prism can automatically correct angle.
