Description
Technical Field
The invention belongs to the technical field of camera motors, and particularly relates to a lens driving telescopic lens barrel structure, a lens driving device and an imaging device.
Background
The miniature camera long-focus lens is widely applied to high-end mobile phones, and the applied image sensor pixels are also improved from 800 ten thousand pixels to more than 1 hundred million pixels, so that the equivalent focal length of the miniature lens is far beyond the thickness of the mobile phone body. Although periscope type motors are a mature solution for mobile phone tele cameras, pixels are greatly improved, the outer diameter of a lens is also larger and larger, and the periscope type motors are limited in application. Therefore, the telescopic camera of the miniature lens barrel not only can solve the problem that the long-focus lens with the oversized pixels is arranged and used on the mobile phone, but also can greatly improve the image quality.
The image pickup apparatus is generally applied to an image pickup motor, which has a focusing function. The existing camera motor structurally comprises a bearing frame for bearing a lens, wherein the bearing frame is moved in the axial direction of an optical axis in an electromagnetic driving mode, and focusing stroke of focusing in the mode is short. The inventor improves on this, and uses the cooperation of the stator and the rotor to drive the bearing frame to focus in the axial direction of the optical axis (for example, chinese patent publication No. CN 101595429B), in such a way that the focusing stroke is increased, and the principle of this way is as follows: the stator drives the rotor to rotate, the stator is arranged on the base or the shell, the rotor is arranged on the bearing frame, the stator and the rotor are in threaded connection to drive the bearing frame to focus in the axial direction of the optical axis, and the stator and the lens in the mode synchronously rotate and move together, so that long axial matching electromagnetic driving force is required, and the manufacturing cost of the stator and the rotor is greatly increased.
Secondly, there is great deviation between the bearing frame axis and the optical axis, and the deviation directly leads to poor final imaging quality, and is difficult to meet the requirement of high-precision imaging.
