Example Embodiment

[0028] Example one:

[0029] For the drive structure of the present invention, see Figure 1 to Figure 4 , Including base 1, module body 2, module drive assembly, deflection assembly, anti-shake drive assembly and monitoring component 5.

[0030] The base 1 includes an upper cover 11 and a base 12. The upper end of the upper cover 11 has an opening 13 for light to pass through. The center line of the opening 13 coincides with the optical axis. A containing cavity is formed in the upper cover 11, the module body 2, the mold The group drive assembly, deflection assembly, anti-shake drive assembly and monitoring component 5 are arranged in the containing cavity. After the base 12 is connected to the upper cover 11, the module body 2, the module drive assembly, the deflection assembly, the anti-shake drive assembly and the monitoring The piece 5 closes the cavity. In order to facilitate the installation of the deflection assembly, a frame 6 for connecting the deflection assembly is a...

Example Embodiment

[0042] Embodiment two:

[0043] The optical image stabilization camera of this embodiment includes the driving structure, image sensor and lens in the first embodiment. The image sensor is fixedly arranged on the module body 2 of the driving structure; the lens is arranged on the module body 2 so as to move toward or away from the image sensor.

[0044] During auto-focusing, the module driving component drives the lens toward or away from the image sensor along the optical axis; in the case of optical image stabilization, the first coil 42 drives the first magnet 41 to move, driving the module body 2 with the first coil 42 around the first When a rotation axis rotates, the second magnet 44 drives the second coil 43 to move, driving the gasket 31 and the module body 2 to rotate around the second rotation axis, so as to realize the deflection movement of the module body 2 deviating from the optical axis.

Abstract

The invention relates to the technical field of camera driving devices, in particular to a driving structure and an optical anti-shake camera. The driving structure comprises a base body, a module body, a module driving component, a deflection component and an anti-shake driving component, wherein the module body is disposed in the base body, and has a fixedly disposed image sensor and a lens moveably disposed relative to the image sensor along an optical axis direction therein; the module driving component is disposed in the module body and connected to the lens, and drives the lens to move toward or away from the image sensor; the deflection component is installed in the base body relative to the movement of the base body, and provided with the module body; and the anti-shake driving component is disposed in the base body, and coupled to the module body for driving the module body to deflect relative to the optical axis. The optical anti-shake camera with the driving structure provided by the invention is higher in imaging quality.

Description

technical field [0001] The invention relates to the technical field of camera drive devices, in particular to a drive structure and an optical anti-shake camera. Background technique [0002] The camera of a mobile phone is an important part of a mobile phone. Consumers have higher and higher requirements for functions such as autofocus and optical image stabilization of the mobile phone camera when using a mobile phone. When realizing the optical anti-shake function, the existing mobile phone camera generally drives the lens to move, and the image sensor remains stationary. In the process of driving the lens, there will inevitably be a deflection movement between the lens and the image sensor, so that the optical axis of the lens cannot be perpendicular to the image sensor when the optical axis anti-shake function is implemented, resulting in blurred edges of the image. With the increase of the pixels of mobile phone camera, the phenomenon of blurred edges will become more...
