Problems solved by technology

However, most of the lens modules for portable electronic devices only have digital zoom function, and do not have optical zoom function
For example, the 1.3 million-pixel lens module of Samsung SCH-E159 and the 1.3 million-pixel lens module of BenQ S700 all support continuous camera function and digital zoom function, but do not support optical zoom function.
[0004] At present, lens modules with more than 3 times optical zoom function are widely used in digital cameras, but their structures are complex and inconvenient to assemble. Usually, motors or magnetic substances are used to realize the focusing function. its power consumption
Therefore, traditional lens modules for digital cameras are not easy to be directly applied to portable electronic devices such as mobile phones.

Abstract

The two-section type focusing mechanism includes one lens module and one base. The lens module has optical assembly and is held inside the base together with an image sensor. The lens module is provided with close shot locating mechanism and distant shot locating mechanism; and the base has corresponding locating lugs. After the lens module moves inside the base along the optical axis, the close shot locating mechanism and the distant shot locating mechanism will match with the lugs. The two-section type focusing mechanism capable of realizing close shot and distant shot may be used in various kinds of portable electronic equipment and has simple structure and low cost.

Description

【Technical field】 [0001] The invention relates to a two-stage focusing mechanism, in particular to a two-stage focusing mechanism suitable for portable electronic devices. 【Background technique】 [0002] At present, portable electronic devices are not limited to the functions of calling and general message management, but also develop towards the direction of multimedia communication, such as the transmission of information such as video and images, and portable electronic devices with camera functions can meet these requirements. [0003] In recent years, due to the rapid development of digital technology, the application of portable electronic devices with camera functions has become more and more popular. However, most of the lens modules for portable electronic devices only have a digital zoom function and do not have an optical zoom function. For example, the 1.3 million-pixel lens module of Samsung SCH-E159 and the 1.3 million-pixel lens module of BenQ S700 all suppor...
