Problems solved by technology

[0004] However, the drive motor often takes up a lot of space and is expensive to manufacture. As a result, the lens module and camera module that use the drive motor to drive the focus are large in size, unable to meet the needs of lightness, thinness and shortness, and the cost is bound to be high.

Abstract

The invention discloses a lens mould, which comprises the following parts: at least one lens, at least one first driving part to drive the lens to move along optical axle toward object side, at least one second driving part to drive lens to move along optical axle towards object side, wherein the first and second driving parts contains front driving piece and back driving piece from object side to image side; the heat bulking factor of back driving piece of the first driving part is more than the heat bulking factor of front driving piece; the heat bulking factor of front driving piece of the second driving par is more than the heat bulking factor of back driving piece. The invention also provides a mould of the lens mould.

Description

technical field [0001] The invention relates to the technical field of focusing drive, and to a lens module and a camera module using the lens module. Background technique [0002] With the development of camera technology, camera modules are widely used in camera devices for various purposes. The combination of camera modules and various portable electronic devices such as mobile phones, video cameras, computers, etc. is favored by many consumers. . [0003] The camera module usually includes a driving motor, at least one lens module driven by the driving motor, and a photosensitive element opposite to the lens module. The lens module may include one or more lenses, the lenses are arranged opposite to the photosensitive element, and the center point of the photosensitive element is located on the optical axis of the one or more lenses. When focusing, use the drive motor to drive the relative displacement of the lens group and the photosensitive element to find a focus pos...
