Lens assembly for a mobile phone equipped with macroshot function

Abstract

The invention relates to a lens assembly for a portable terminal with a macro function, comprising: a lens barrel installed on the lens; a support unit for accommodating the lower end of the lens barrel; A macro drive unit with an inclined guide inclined surface formed around the periphery of its upper end; it is located between the support unit and the macro drive unit, contacts its upper side along the outer side of the macro drive unit, and elastically supports the macro drive upwards The elastic part of the unit is fixed on the upper end of the support unit at a certain distance, and its guide protrusion can press down the protective cover of the guide inclined surface of the macro drive unit. At this time, the elastic member may be a leaf spring that surrounds and is integrated with the outside of the lens barrel contained in the support unit. The invention can not only improve the convenience of assembly, but also make the macro drive unit located outside the lens barrel, prevent impurities inside the lens barrel during macro drive, and greatly improve the concentricity and focusing function of the lens.

Description

Technical field [0001] The present invention relates to a camera device for a portable terminal, in particular to a lens assembly for a portable terminal with a macro function (LENS ASSEMBLY FOR A MOBILE PHONE EQUIPPED WITH MACRO FUNCTION). Background technique [0002] Recently, in addition to providing inherent voice call functions, portable terminals also provide diversified value-added functions such as wireless Internet access and multimedia playback. Many mobile phones appearing on the market now have small camera modules that can shoot still images or videos. Such mobile phones are commonly known as camera phones. [0003] However, this kind of portable terminal, that is, the existing lens assembly installed on a camera phone cannot fully reflect functions such as zoom and macro (close-up) due to factors such as installation space constraints. Therefore, generally the object image of the subject located at infinity passes through the lens and then is imaged on a photosensi...

AI Technical Summary

Problems solved by technology

[0009] According to the aforementioned mechanism, since the inclined groove is located on the outer cylindrical surface of the first lens barrel, the pin protruding from the lens group is not easily combined with the inclined groove of the first lens barrel, and since the first lens barrel that helps the lens group vertically align and performs macro The function of the first lens barrel is independently produced, the concentricity and position of the lens group are not easy to adjust, and it is not easy to adjust the lens focus after assembly

In addition, since the first lens barrel, which rotates to adjust the focus position, is adjacent to the lens group, impurities are generated due to friction between the inclined groove of the first lens barrel and the protruding pins of the lens group, thereby contaminating the inside of the lens barrel or the lens surface.

[0010] As mentioned above, the existing lens components for portable terminals cannot ensure the focal length sufficient to realize the macro function. The components provided to solve the above problems are not easy to assemble because of their complex structure, and it is not easy to adjust the concentricity and focus of the lens.
