Title:
AUTO-FOCUS DRIVING ASSEMBLY, LENS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/216153
Kind Code:
A1
Abstract:
Provided is an auto-focus driving assembly. The auto-focus driving assembly is applied to an electronic device (100) containing a lens and a sensor, and light entering the lens reaches the sensor (242) through the auto-focus driving assembly. The auto-focus driving assembly comprises: a driving motor for driving the lens to move; a housing (530) for accommodating the driving motor; and a first shading body (554) arranged on an inner wall of the housing (530) and configured for preventing light irradiating on the first shading body (554) from reflecting back into a cavity of the housing (530). The first shading body (554) is arranged on the inner wall of the housing (530), and when the light irradiates on the first shading body (554), the effect of light extinction is achieved, and a halo of a light-spray type or column shape, for example, can be eliminated; and a margin is reserved for the machining precision of the lens.
