Two-axis anti-shaking pan-tilt and camera device

Abstract

The invention discloses a two-axis anti-shaking pan-tilt and a camera device. The two-axis anti-shaking pan-tilt comprises an outer-layer support, a middle-layer support and an inner-layer support arranged sequentially from outside to inside, wherein the outer-layer support is used as a fixing piece and is provided with a first magnetic component group; the middle-layer support is used as a rotating piece around an X axis and is axially connected in the outer-layer support; the inner-layer support is used as a rotating piece around a Y axis and a bearing piece for a camera module, is axially connected in the middle-layer support and is provided with a second magnetic component group; and the mutual acting force of a magnetic field between the first magnetic component group and the second magnetic component group drives the middle-layer support to rotate around the X axis relative to the outer-layer support and drives the inner-layer support to rotate around the Y axis relative to the middle-layer support, and orthographic projections of the X axis and the Y axis on an anti-shaking plane are orthographic. According to the two-axis anti-shaking pan-tilt, during the anti-shaking process, the camera module does not generate translation on the anti-shaking plane, rotation shaking prevention in the true sense can be realized, a larger anti-shaking angle is realized, and the two-axisanti-shaking pan-tilt and the camera device are applicable to a large-angle anti-shaking scene such as an unmanned aerial vehicle and a recorder.

Description

technical field [0001] The invention relates to the field of photography, in particular to a two-axis anti-shake platform and a photography device. Background technique [0002] The anti-shake gimbal is a device for carrying a camera module and performing optical anti-shake on the camera module. It is widely used in drones and selfie sticks. At present, most anti-shake gimbals adopt passive anti-shake in the form of shock absorption and active anti-shake in the form of movement. Active anti-shake in the form of movement generally uses servos or motors to drive the camera module to make a movement that is opposite to the vibration direction and has a similar amplitude. To counteract vibration, the cost is high, the weight is large and the structure is complicated. [0003] In a patent document whose publication number is CN107340667A, a kind of anti-shake micro-head is disclosed, which includes an inactive structure composed of a shell, a positioning seat and a magnet, and a...

But strictly speaking, during the anti-shake process, the camera module 1' does not actually rotate around the X-axis and Y-axis, but tilts (Tilt) toward the X-axis and Y-axis, because under the interaction force of the magnetic field , the camera module 1' will inevitably generate a certain amount of translation on the XY plane, which limits the anti-shake angle of the camera module 1', therefore, the traditional shifting OIS structure is not suitable Do large-angle anti-shake on the gimbal
