Problems solved by technology

However, assembling and locking the lens group 11 into the accommodating seat 10 does not actually require such a complicated mechanism design; such a complicated mechanism design increases the production cost, not only increases the overall outer diameter of the lens module 1, but also causes the lens module 1. The overall increase in volume and weight also makes it difficult to assemble and lock the lens group 11 into the housing 10

Embodiment Construction

[0017] The main principle of the miniaturized lens module of the present invention is to use the principle of different sizes of the lenses of the lens group to provide screw teeth at the smaller lenses in the lens group, so that the screw teeth can be embedded within the maximum outer diameter of the lens group. When the lens group is rotated and locked in the housing to complete the lens module, because the thread of the lens group is embedded within the maximum outer diameter of the lens group, the overall outer diameter of the lens module can be reduced, that is, the size of the lens module is reduced. The volume makes the lens module more miniaturized and has a wider range of applications. Along with the reduction in the overall volume, the weight of the lens module is also reduced, so the power consumed to drive the lens module per unit time is reduced, so that when using a power supply device with the same capacity, the standby and use time of the product can be effectiv...

Abstract

The invention relates to a micro-module of lens, suitable for lens device to reduce the whole outer diameter of the whole lens device. This micro-module of lens has a seat and a lens block. This seat has a full bore, part of internal wall of full bore has the female thread, and the radius of this full bore with female thread less than that without this female thread. This lens set is arranged in this full bore, the rim of this lens corresponding to this female thread has a matched male thread, and the radius of lens set with this male thread is less than that of lens set without the male thread, so the seat combined with this lens set may effectively reduce the whole outer diameter of lens module, ensure this lens module more compact, and easier to assemble.

Description

technical field [0001] The present invention relates to a miniaturized lens module and a lens device with the miniaturized lens module, in particular to a method in which the threaded teeth of the lens group are arranged at the front end and matched with the threaded teeth arranged at the front end of the accommodating seat to effectively control the lens module Minimization of overall size. Background technique [0002] Please refer to FIG. 1A and FIG. 1B , which are schematic cross-sectional diagrams of a conventional lens module disassembled and assembled, respectively. The conventional lens module 1 includes: a housing seat 10 and a lens group 11, wherein an inner thread 101 is provided on the inner edge of the housing seat 10, and an outer screw thread is provided on the outer edge of the lens group 11. tooth 111, the lens group 11 is locked into the housing 10 by the front end of the housing 10, and the inner thread 101 of the housing 10 is locked with the outer threa...
