Problems solved by technology

However, in this solution, since there is no rotation axis between the lens and the bracket to rotate, so when the magnets on both sides generate opposite forces to control the tilt of the lens, the rotation of the lens relative to the bracket will often be unstable due to the difference in control speed, and there is no constant Pivot point makes lens stops less effective

Embodiment 1

[0044] refer to Figure 4 , in this embodiment, the support mechanism has four supporters 30, which are respectively arranged on two opposite sides of the X-axis and two opposite sides of the Y-axis in the moving structure 20. The supporter 30 is installed on the support structure 10 to support the corresponding side of the mobile structure 20 on the support structure 10 . In this embodiment, the mobile structure 20 is movably installed on the support structure 10 through the support of the supporter 30 , and there is no need to set other movable mounting brackets between the mobile structure 20 and the support structure 10 , such as guide rails, suspension components, etc., and the structure is simple.

[0045] refer to Figure 5 to Figure 8a , the supporter 30 includes two transmission arms 31 and constraints, and the two transmission arms 31 are arranged symmetrically on both lateral sides of the center line along a longitudinally extending center line and are respectively...

Embodiment 2

[0089] refer to Figure 8b , is the second embodiment of the present invention, which is different from the first embodiment. In this embodiment, the first end 301 of the transmission arm 31 and the support frame 11 can slide relative to the support frame 11 while being connected to the support frame 11 through the sliding track 35 turn.

[0090] A spring 34a is arranged between the first end 301 of the transmission arm 31 and the support frame 11, and the spring 34a is a cylindrical spring and provides stretching elastic force to the first end 301, that is, to provide the first end 301 of the two transmission arms 31. Stay away from the stretch. Of course, other springs can also be used, not limited to cylindrical springs.

[0091] The restraining member includes a sliding track 35 , a driving member 32 and a spring 34 a. The sliding track 35 exerts a longitudinal restraining force on the first end 301 so that the first end 301 is restrained at a corresponding height. The ...

Embodiment 3

[0094] refer to Figure 9a , is the third embodiment of the present invention, which is different from the above-mentioned embodiments. In this embodiment, the front end of the bendable structure 311a is arc-shaped, and the two transmission arms 31a are two independent parts, and the two bendable structures 311a are arranged symmetrically. It is in the shape of a "person" or an inverted "Y". The bendable structure 311a is a structure bent on a longitudinal plane, which is arc-shaped in a reset state.

[0095] The bendable structure 311b is a bendable elastic sheet or elastic strip made of elastic sheet or wire with elastic deformation capability.

Abstract

The invention discloses a support device, which is used for providing a pivot point relative to a support structure for a mobile structure when the inclination angle of a camera is adjusted. The support device comprises two transmission arms and a constraint piece, the two transmission arms are symmetrically arranged along a longitudinal center line respectively and have a certain included angle; the first end of the transmission arm is movably connected to the supporting structure and can move relative to the transverse direction, the second end of the transmission arm is fixed to the moving structure, the position, close to the second end, of the transmission arm forms an elastic bendable structure capable of deforming, bending or bending along a longitudinal face, and the second end is close to the center line relative to the first end so as to support the corresponding side of the moving structure. A virtual pivot point is formed at the intersection point of the two transmission arms, and the restraining piece restrains the longitudinal position and the transverse position of the first end. The support device provides a pivoting point for a moving structure while supporting the moving structure, and is stable in rotation and good in anti-shaking effect under the condition that a rotating shaft is not increased. The invention further discloses a driving device for adjusting the inclination angle of the camera.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to the technical field of camera anti-shake. Background technique [0002] As miniature auto-focus cameras are widely used in mobile phones, cars, unmanned aircraft, security monitoring, smart homes and other products. Ordinary miniature auto-focus camera modules are driven by a miniature voice coil motor to move the lens up and down in the direction of the optical axis. When taking pictures, the control chip drives the voice coil motor to move, thereby realizing the auto-focus function. When taking pictures or videos, the lens will not be kept absolutely stable due to human shaking or other reasons, resulting in a certain offset. At this time, an actuator is required to adjust the inclination angle of the camera. When adjusting the inclination angle of the transmission, it is often necessary to rotate the camera and install it on the support On the frame, a plurality of rotating s...
