A driving device for zoom function of line of sight of mobile image sensor

Abstract

The invention discloses a driving device for moving the zoom function of the line of sight of an image sensor, comprising: a base, a mover module assembly movably connected to the base, a hook assembly fixed at the corner of the base, and a hook assembly fixed on the The first group of coils and the second group of coils on the base, the first group of coils and the second group of coils are provided with Hall chips, and the Hall chips are fixed on the base; the mover module assembly is set In the base, and the mover module assembly is located directly above the first set of coils and the second set of coils and arranged at intervals, and the first set of coils, the second set of coils and the Hall chip constitute a closed-loop control module; the mover The corners of the sub-module components are elastically connected to the hook components, and the closed-loop control module controls the driving adjustment of the position of the sub-module components in the X-Y axis. According to the present invention, the OIS anti-shake effect is realized in the mode of only driving the image sensor and not driving the lens.

Description

technical field [0001] The invention relates to the technical field of driving devices, in particular to a driving device for zooming function of the line of sight of a mobile image sensor. Background technique [0002] The photos taken by electronic devices such as mobile phones sometimes appear blurry during the shooting process, that is, the captured pictures are not clear enough, and ghosting or blurring occurs. These reasons, except for occasional out-of-focus (that is, the camera lens fails to focus normally), are largely due to the slight jitter when the scene is exposed. Generally speaking, this kind of extremely slight shaking phenomenon often occurs under handheld conditions, so the demand for the development of anti-shake technology functions is relatively large in recent years. In this context, proposals for OIS (Optical Image Stabilization System) optical image stabilization functions have also increased, and micro-optical image stabilization technology has gra...

Problems solved by technology

However, the structure of the translational zoom motors currently on the market is still somewhat uncomplicated, and has the characteristics of low manufacturing yield and poor reliability, which lead to a series of problems such as high cost and difficulty in universal promotion.
