Referring to Figure 1 and Fig. 2, it is a preferred embodiment of the utility model, provides a kind of lens module, including camera lens Cylinder 1, several eyeglasses 2, washer 3 and several anti-dazzling screens 4 being contained in barrel 1.

The present embodiment elaborates to this implementation by taking the lens module of a 4P as an example below.

The lens module of the present embodiment has four pieces of eyeglasses 2, wherein including the first eyeglass 2a and the second eyeglass 2b, first Eyeglass 2a is stacked and placed on above the second eyeglass 2b.

The bottom of first eyeglass 2a has the first circular step 21a and the second circular step 22a, wherein is located at outside The first circular step 21a be higher than positioned inside the second circular step 22a.Optionally, first circular step of the present embodiment 21a and the second circular step 22a is plane.

The top surface of second eyeglass 2b has a cricoid sunk structure 21b by the region of proximal edge, and sunk structure 21b's is interior Side direction has a cricoid bulge-structure 22b, and the lateral direction of sunk structure 21b has a cricoid breasting plane 23b.

In the second circular step 22a of the eyeglass 2a of the bulge-structure 22b insertion first of the above-mentioned top surface second eyeglass 2b, the The first circular step 21a of breasting plane 23b the first eyeglass of support 2a of two eyeglass 2b.

By the way that sunk structure 21b is arranged in the top surface of the second eyeglass 2b, it can reduce and bear against plane 23b at the top of the second eyeglass 2b Area, advantageously reduce the reflection of stray light, improve the image quality of lens module.Meanwhile second eyeglass 2b have protrusion Structure 22b and bear against plane 23b, the two can first eyeglass 2a of the support above it, also, the bulge-structure of the second eyeglass 2b 22b can be chimeric with the second circular step 22a of the first eyeglass 2a, steady after ensure that the first eyeglass 2a and the second eyeglass 2b assembling It is qualitative, in order to stop stray light, anti-dazzling screen 4 is also gripped between bulge-structure 22b and the second circular step 22a.In addition, mutually Chimeric the first eyeglass 2a and the second eyeglass 2b is not necessarily to design the contact plane of large area, is conducive to contract lenses 2 and mirror The size of head mould group, so that lens module can be applied to need the electronic product of tiny lens or the limited electronics of installation space produces In product.

Further, the surface of the sunk structure 21b of the second eyeglass 2b does delustring processing or is covered with extinction layer 24b；From And the stray light being irradiated on the surface sunk structure 21b can be eliminated or weaken, improve image quality.

Refer to Fig. 3, the bottom surface of the second eyeglass 2b also has a sunk structure 25b by the region of proximal edge, bottom surface it is recessed Fall into the sunk structure 25b of structure 21b alignment top surface.It is easily understood that the sunk structure 25b of the second bottom surface eyeglass 2b can also subtract The contact area of few itself and the third eyeglass 2c of lower section, also, pass through the support of anti-dazzling screen 4, it is ensured that the second eyeglass 2b and the Stability after three eyeglass 2c assembling.

In order to cooperate the small size for being located at 1 top eyeglass 2 of barrel to design, the barrel 1 of the present embodiment includes stub end 11 and small head end 12, the bottom of small head end 11 be connected with the top of stub end 12, the inner space of the two is interconnected；And And the diameter of 11 inner space of stub end be greater than small 12 inner space of head end diameter, the first eyeglass 2a, the second eyeglass 2b and Third eyeglass 2c is contained in the inner space of small head end 12, so that the top of lens module can be designed smaller,

For the ease of molding, the eyeglass 2 of the present embodiment is made up of plastic material of injection molding process.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
