Lens module

Abstract

The present invention provides a lens module, which includes an image sensing module and a voice coil motor fixed on the image sensing module; The first coil group and the second coil group for focusing; the image sensing module includes a base and an elastic element, and the base includes an upper surface and a lower surface opposite to the upper surface; A groove is opened on the upper surface, and an elastic element is arranged in the groove, and one end of the elastic element protrudes from the upper surface; the lower cover is pressed against the upper surface of the seat body and the elastic element superior. By ensuring the alignment accuracy of the voice coil motor and the image sensor module during the assembly process, and by fixing the first coil group on the movable barrel to compensate the shake of the lens module during operation, the imaging of the lens module is effectively improved quality.

Description

technical field [0001] The invention relates to an image taking device, in particular to a lens module. Background technique [0002] The lens module generally includes a lens, a voice coil motor and an image sensing module. The voice coil motor is fixed above the image sensing module, and the lens is movably accommodated in the voice coil motor. The voice coil motor drives the lens to move relative to the image sensing module to achieve focusing. [0003] However, when the lens module is used to shoot images, the shake of the photographer will cause the image to be blurred. Traditional anti-shake devices compensate for shaking by moving the image sensor in the image sensor module, but the structure of the traditional anti-shake device is complicated, and it is independent of the focusing structure of the voice coil motor, so that the cost is relatively high. high. [0004] In addition, since the voice coil motor is directly carried on the image sensing module, if the vo...

[0003] However, when using the lens module to shoot images, the image will be blurred due to the shake of the photographer

The traditional anti-shake device compensates for the shake by moving the image sensor in the image sensor module, but the structure of the traditional anti-shake device is complicated, and it is independent of the focusing structure of the voice coil motor, so that the cost is relatively high. high

[0004] In addition, since the voice coil motor is directly carried on the image sensing module, if the voice coil motor is tilted relative to the image sensing module, it is difficult to adjust the inclination of the voice coil motor relative to the image sensing module during the assembly process. The optical axis between the voice coil motor and the image sensing module is not on the same straight line, which affects the imaging quality of the image sensing module
