Embodiment Construction

[0022] refer to figure 1 , the lens module 100 of the first embodiment includes a lens barrel 10 , two lens groups 11 , two brackets 12 , a focusing element 13 and a driving element 14 .

[0023] refer to figure 2 , an opening 102 extending axially along the lens barrel 10 is formed on the lens barrel 10 . The opening 102 is generally rectangular. Of course, the two ends of the opening 102 can also be processed into an arc shape.

[0024] see also image 3 and Figure 4 , each bracket 12 includes a mounting portion 121 and a bar-shaped actuating portion 122 extending outward from the mounting portion 121 . The mounting portion 121 is cylindrical, and the lens group 11 is installed therein. The lens group 11 includes at least one lens. In this embodiment, one lens is taken as an example for illustration. The mounting portion 121 is integrally disposed on the inner surface of the side wall of the lens barrel 10 . The mounting portion 121 is slidably assembled with the le...

Abstract

The invention relates to a lens module, which comprises a lens barrel, at least two lens groups, at least one support and a focusing piece, wherein the lens barrel is provided with an opening which extends along the axial direction of the lens barrel; the support comprises a mounting part and an actuating part connected with the mounting part; at least one groove extending along a preset path is formed on the focusing piece; at least one lens group is mounted on the mounting part of the support; the mounting part is received in the lens barrel; and the actuating part passes through the opening and the end parts of the actuating part are arranged in the groove of the focusing piece in a sliding mode. The lens module can change the focus of the lens barrel through horizontal movement of the focusing piece, and has the advantages of simple integral driving structure, simple and convenient mounting and low cost. The invention also provides a camera module and a portable electronic product adopting the lens module.

Description

technical field [0001] The invention relates to a lens module and a camera module including the lens module. Background technique [0002] The camera module usually includes at least one lens module and an image sensor arranged opposite to the lens module. The lens module includes optical elements such as a lens barrel and lenses accommodated in the lens barrel. The image sensor is packaged in on a circuit board. Such camera modules are built into various portable electronic devices, such as mobile phones, camcorders, multimedia players, computers, etc., and are favored by many consumers. [0003] In order to achieve zooming, this type of camera module is usually provided with a driving structure, such as a cam groove with varying heights on the inner wall of the lens barrel, and a cam pin on the outer edge of the lens, so as to drive the relative movement of the lenses in the lens module. Alternatively, two driving structures, such as stepping motors, are provided to resp...
