The present disclosure provides a camera apparatus, an SMA driving device and a manufacturing method, a driving method and a wiring method, wherein the SMA driving device further comprises a lens carrier, at least one upgoing driver, and at least one downgoing driver; wherein the lens carrier is connected to the upgoing driver, and the upgoing driver supports the lens carrier upwardly in a thermally driven manner, and pulls the lens carrier to move upward; wherein the lens carrier is connected to the downgoing driver, and the downgoing driver draws the lens carrier downwardly in a thermally driven manner, and pulls the lens carrier to move downward; and wherein the lens is disposed on the lens carrier of the SMA driving device, and the SMA driving device drives the lens to move up and down, thereby improving the focusing speed of the lens.

Camera apparatus, SMA driving device and manufacturing method, driving method and wiring method thereof

An optical actuator, including: a base; a lens module comprising two first side surfaces opposite each other; and a plurality of shape memory alloy wires forming two wire groups, the two wire groups being disposed on the two first side surfaces, respectively, wherein two ends of each shape memory alloy wire are fixed to a base-end fixing device and a lens-end fixing device, respectively; and the direction of the resultant force acting on the lens module by the two wire groups is consistent with the direction of the optical axis of the lens module, so that the lens module is driven to move along the direction of the optical axis of the lens module by means of expansion and contraction of the shape memory alloy wires of the two wire groups.

Optical actuator, and corresponding camera module and camera module array

An optical assembly, a camera module having the optical assembly, and a smart device having the camera module. The optical assembly comprises: a lens module () having an outer frame (), wherein the outer frame () comprises four side surfaces divided according to an angle range, the lens module () comprises a first support portion () and a second support portion () on each side surface of the outer frame (), and both the first support portion () and the second support portion () on each side surface are located at a group of diagonal regions (A) of the outer frame (); and a fixing means () disposed at another group of diagonal regions (B) of the outer frame () of the lens module (), wherein the fixing means () has a first power supply fixing portion () and a first groundwire fixing portion () corresponding to the first support portion (), and a second power supply fixing portion () and a second groundwire fixing portion () corresponding to the second support portion (), on a respective fixing surface corresponding to each side surface of the outer frame ().
