Single-shaft motor

Abstract

The invention discloses a single-shaft motor. The single-shaft motor comprises a mounting seat, a carrier and at least one driving assembly, the mounting seat comprises a first side wall and a second side wall which are arranged at an interval and a first mounting plate connected between the first side wall and the second side wall, the carrier comprises a second mounting plate and first and second rotating shafts convexly arranged at two ends of the second mounting plate, and the first and second rotating shafts are respectively pivoted to the first and second side walls; each driving assembly comprises a driving arm and a memory alloy wire, one end of the driving arm is mounted on the first mounting plate, the other end of the driving arm is connected to one end of the memory alloy wire, and when the memory alloy wire is heated to shrink, the driving arm can generate elastic deformation to act on the second mounting plate, so that the carrier is driven to rotate around the first rotating shaft and the second rotating shaft; according to the single-shaft motor, jumping or shaking in the rotating process can be reduced through the rotating shaft, the carrier can rotate stably, the adjusting precision can be improved, the carrier has the large rotating angle, and therefore the single-shaft motor can be used for achieving the scanning function or the anti-shaking compensation function, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a single-axis motor with large adjustment angle and low adjustment power consumption. Background technique [0002] Now users have higher and higher shooting requirements for electronic devices (such as mobile phones, tablet computers, etc.), so the camera modules configured on electronic devices are becoming more and more diverse, such as panoramic shooting, wide-angle shooting, telephoto shooting, etc. Wait. [0003] The current method of shooting a panorama is generally that the user holds the electronic device and rotates it in a horizontal or vertical position. The camera records the image and combines it with software to obtain a panoramic photo. Since the user will inevitably shake when rotating the electronic device, the rotation speed is also The time is fast and the time is slow, so the final composite photo may be misaligned or stretched, which will affect the...

Problems solved by technology

Since the periscope camera module folds the optical path, the requirements for optical image stabilization (OIS: Optical image stabilization) are higher. At present, the common way is to drive the prism assembly to rotate through an electromagnetic drive device or an electro-deformation drive device. Optical anti-shake is realized, but there are disadvantages of small anti-shake angle and poor anti-shake effect. In addition, the electromagnetic drive device also leads to a larger camera module and higher power consumption during adjustment.
