Description

A kind of lens module

Technical field

The utility model relates to optical image technology field, in particular to a kind of lens module.

Background technique

With the continuous development of science and technology, electronic equipment is portable other than digital camera constantly towards intelligent development Electronic equipment such as tablet computer, mobile phone etc. are also provided with the lens module for camera function of taking pictures, and are clapped at any time with meeting user According to needs.The lens module of the relevant technologies include barrel, the eyeglass being set in the barrel, be held on it is two neighboring Anti-dazzling screen or barn door between eyeglass and the pressure ring between bottom eyeglass and the barrel.

At least there are the following problems in the prior art for inventor's discovery: when anti-dazzling screen being bonded with eyeglass by viscose glue, institute To be easy to generate gas, since anti-dazzling screen and two eyeglasses for clamping the anti-dazzling screen form one by being heating and curing with viscose glue A airtight cavity so that lens module inner and outer air pressure is uneven, cause flatness between each electronic component of lens module by It influences, to influence the imaging performance of lens module.

Utility model content

The purpose of this utility model is to provide a kind of lens modules, it is ensured that imaging performance is not by effects of air pressure.

In order to solve the above technical problems, the embodiments of the present invention provides a kind of lens module, comprising:

Barrel with accommodating space and the lens set being contained in the accommodating space, the lens set have light Axis and the first eyeglass and the second eyeglass that are spaced apart from each other are included at least, the lens module further includes being located in first eyeglass With the anti-dazzling screen between second eyeglass, the anti-dazzling screen offers through-hole around the optical axis, the anti-dazzling screen with it is described First eyeglass and second eyeglass enclose jointly and set to form cavity, and the anti-dazzling screen includes the first mounting portion for being spaced apart from each other setting With the second mounting portion, first mounting portion is greater than second mounting portion along the optical axis side along the thickness of the optical axis direction To thickness, the first installation part do not abut first eyeglass and second eyeglass；Second mounting portion and institute Any one interval setting in the first eyeglass and second eyeglass is stated, the cavity is through second mounting portion and the receipts Hold space connection.

The utility model embodiment in terms of existing technologies, connection cavity is provided on anti-dazzling screen and receiving is empty Between the second mounting portion so that cavity is no longer a closed cavity, produced by lens module is in the environment of high temperature and humidity Gas can be discharged from cavity via accommodating space, it is ensured that lens module inside and outside air pressure balance, to keep lens module each Flatness between electronic component will not be affected because lens module inner and outer air pressure is uneven, it is ensured that the imaging of lens module Performance is not by effects of air pressure.

In addition, the anti-dazzling screen includes the inner wall for surrounding the light hole, is oppositely arranged with the inner wall and separate The outside wall surface of optical axis, the end face for connecting the inner wall and the outside wall surface, second mounting portion and adjacent described first Mounting portion surrounds the groove that the outside wall surface is extended to from the inner wall, and the groove is connected to the cavity and the receiving is empty Between.Such structure makes lens module without increasing additional structure so that accommodating space is connected to cavity, need to be in anti-dazzling screen On open up fluted, simplify the processing flow of lens module.

In addition, the end face includes the object side close to object side and the image side surface close to image side, the object side is towards described Image side surface is recessed to form second mounting portion.

In addition, the groove be it is multiple, multiple grooves are parallel two-by-two.By the way that multiple grooves are arranged, so that camera lens mould The gas generated in group can be discharged faster, further ensure that flatness between each electronic component of lens module will not be because Lens module inner and outer air pressure is uneven and is affected, and improves the imaging performance of lens module.

In addition, the groove extends to the outside wall surface from the inner wall along the radial direction of the anti-dazzling screen.

In addition, the groove be it is multiple, multiple grooves are arranged at equal intervals around optical axis.Such structure makes anti-dazzling screen Breasting face with the first eyeglass and the second eyeglass is also to surround optical axis to be arranged at equal intervals, to make anti-dazzling screen in lens module Uniform force in motion process avoids anti-dazzling screen and damages because of unbalance stress, improves the reliability of lens module.

In addition, the groove forms the first opening in the inner wall, the groove forms second in the outside wall surface and opens Mouthful.

In addition, the size of first opening is equal to the size of second opening.

In addition, the size of first opening is less than the size of second opening.
