A three-axis autofocus anti-shake periscope motor

Abstract

The invention discloses a three-axis autofocus anti-shake periscope motor, comprising: a base, a frame arranged on the base, a carrier arranged in the base, and a shell fitted with the base; The Z-axis drive assembly is attached with a Z-axis closed-loop circuit assembly, and the carrier is attached with a Y-axis closed-loop circuit assembly. The Z-axis closed-loop circuit assembly includes a Z-axis circuit board and a Z-axis circuit board arranged on the Z-axis circuit board. The Z-axis Hall chip and the X-axis Hall chip, the Y-axis closed-loop circuit assembly includes a Y-axis circuit board and a Y-axis Hall chip arranged on the Y-axis circuit board. According to the present invention, the overall integration of the motor is high, which is convenient for centralized detection, avoids technical dark corners, meets the requirements of high-quality cameras, reduces the difficulty of tooling and processing, and reduces costs.

Description

technical field [0001] The invention relates to the technical field of lens motors, in particular to a three-axis auto-focusing anti-shake periscope motor. Background technique [0002] The voice coil motor is a device that uses the interaction between the magnetic field from the permanent magnet steel and the magnetic field generated by the energized coil conductor to generate regular motion, and is widely used in electronic devices such as mobile phone cameras. With the development of technology, many electronic devices (such as tablet computers or smart phones) nowadays have the function of taking pictures or videos. Through the setting of the long focal length lens system, the user can take pictures with different effects, so that the electronic device with the long focal length lens system is also gradually loved by the public. [0003] When a lens with a longer focal length needs to be installed in the aforementioned electronic device, it will increase the thickness o...

Problems solved by technology

However, when the electronic device is shaken, the position where the incident light reaches the sensor component may be shifted from a predetermined position, resulting in unclear imaging produced by the lens system.

In addition, the current periscope camera structure uses the rotation of the prism motor and the movement of the periscope motor in two directions to achieve the purpose of three-axis motion control, but the problem is that the rotation of the prism motor will cause imaging vignetting, and the two components are due to Control problems caused by differences in movement methods, so the dimensional accuracy requirements for relative positions are more stringent, and the difficulty of processing and assembly increases, which may increase manufacturing costs and assembly costs
