Description

A kind of lens module

[technical field]

The utility model relates to pick-up lens fields, more particularly 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. is also provided with lens module.In order to meet people's needs, to camera lens mould Higher requirements are also raised for the object image quality that group is shot.

However, since glass lens outer diameter precision is bad, outer diameter cannot be with barrel in existing lens construction Internal diameter directly cooperates, generally with barrel male-female engagement；But since cooperation precision is not very good in practical forming process, The case where often will appear assembly failure, influences the assembling property of camera lens.

There are still very big rooms for improvement for existing fit system, and the cooperation in order to realize glass lens and each component is more steady It is fixed, and the overall performance of camera lens is improved, therefore, it is necessary to provide a kind of novel lens module.

[utility model content]

To solve the above-mentioned problems, the utility model provides a kind of lens module, the lens module include barrel and The lens set being contained in barrel, the barrel include the first barrel of horizontal direction extension, bend and prolong from the first barrel The second barrel stretched；The lens set includes at least the first eyeglass matched with the inner wall of barrel；First eyeglass The outer radius portion of container is fixed and had including main part and with main part, and main part is glass, and outer radius portion is Plastic cement；The container is fixed in the peripheral portion receiving of the main part；The outer radius portion is matched with the barrel.

As an improvement the edge thickness of the main part is equal to the width of the container.

As an improvement the container is from the end face of the close optical axis of outer radius portion to close to barrel inner wall The recessed portion of direction recess, the container include the groove bottom parallel with optical axis and from slot bottom towards horizontal close to optical axis direction The first trough wall surface and the second trough wall surface extended.

As an improvement the outer rim end face of the main part fits with the groove bottom, first trough wall surface It is bonded with the object lateral parts of the peripheral portion of the main part, the peripheral portion of second trough wall surface and the main part The fitting of image side surface part.

As an improvement the main part and the outer radius portion are integrally formed.

As an improvement the object side of the outer radius portion includes to fit with the image side surface of first barrel The inner wall face interval of one plane, first plane and the second barrel is arranged.

As an improvement the outer rim end face of the outer radius portion is connected to the inner wall of second barrel.

As an improvement the main part and first barrel interval are arranged.

The beneficial effects of the utility model are:

The utility model lens module is by being made of original whole glass lens two parts of two kinds of materials, Ke Yibao Eyeglass outer-diameter accuracy is demonstrate,proved, and more accurate with barrel cooperation, is not in assembling problem not in place, to improve product Assemble yield；Cooperate precision high, cooperation is more stable, improves the overall performance of camera lens to a certain extent.

[specific embodiment]

The utility model is described in further detail below by specific embodiment combination attached drawing, so as to more preferably Ground understands the advantages of the embodiment of the utility model and its various aspects.Below in an example, the left and right directions of paper is claimed For horizontal direction, and the up and down direction in the direction vertical with horizontal direction of paper, i.e. paper is known as vertical direction.In this reality In novel, the direction of central axis is parallel with vertical direction.

As depicted in figs. 1 and 2, the utility model provides a kind of novel lens mould group, which includes 1 He of barrel The lens set 2 being contained in barrel 1, wherein lens set 2 includes at least the first eyeglass 21 matched with barrel 1.

In the present embodiment, as shown in Fig. 2, barrel 1 includes first for forming light hole 3 and horizontal direction extension Wall 11 encloses the receiving for setting and being formed from the second barrel 12 of the first barrel 11 bending extension and by the first barrel 11 and the second barrel 12 Space, wherein the first barrel 11 includes the first surface 111 close to image side and the second surface 113 close to object side；Barrel 1 It can be integral structure, be also possible to separate structure.

In order to improve cooperation precision, the assembling yield of the first eyeglass 21 and barrel 1, the structure of the first eyeglass 21 is carried out It improves, concrete scheme is as follows:

As shown in figure 3, the upper surface of the first eyeglass 21 is object side, the lower surface of the first eyeglass 21 is image side surface；First Eyeglass 21 includes main part 22 and the outer radius portion 24 with container 23, and the fixation of main part 22 is contained in container 23 It is interior, wherein main part 22 is glass, and outer radius portion 24 is plastic cement, such as molding obtains main part in glass-forming die Divide 22, post forming obtains the first eyeglass 21 with plastic cement outer radius portion 24 in plastic forming die main part 22.

Further, the width of edge thickness with container 23 of main part 22 is equal；Outer radius portion 24 and barrel 1 It matches, specifically, the object side 21A in outer radius portion 24 of the first eyeglass 21 includes the first surface with the first barrel 11 The inner wall face interval of first plane 241 of 111 fittings, the first plane 241 and the second barrel 12 is arranged；The outer rim of outer radius portion 24 End face 233 is connected to the inner wall of the second barrel 12；Container 23 is from the end face of the close optical axis X of outer radius portion 24 to close The recessed portion of 1 inner wall direction of barrel recess, container 23 include the groove bottom 231 parallel with optical axis X and from groove bottom 231 To close to horizontal-extending first trough wall surface 232 of optical axis X-direction and the second trough wall surface 233；The outer rim end face 221 of main part 22 It fits with groove bottom 231；First trough wall surface 232 is bonded with the object lateral parts of the peripheral portion of main part 22, the second cell wall Face 233 is bonded with the image side surface part of the peripheral portion of main part 22, referring specifically to Fig. 3.

In said structure, main part (i.e. glass part) 22 does not cooperate directly with 1 inner wall of barrel, and and camera lens 1 interval setting of cylinder, passes through the outer radius portion (i.e. plastic portions) 24 and 1 inner wall of barrel being molded as one with main part 22 Cooperation is formed, the outer-diameter accuracy of eyeglass had both been ensure that, and had also ensured the cooperation precision of eyeglass and barrel, is not in assemble not The problem of in place, is to improve the assembling yield of product.

In addition, lens set 2 can also include the second eyeglass 25 of image side positioned at the first eyeglass 21, third eyeglass 26, the Four eyeglasses 27, the 5th eyeglass 28 and the 6th eyeglass 29 etc., above-mentioned eyeglass can be glass lens, or plastic lens or The eyeglass of other materials.In addition, the number of lenses in lens set 2 is not limited only to this.In addition, shading can be set between the lenses Part, shading piece can be anti-dazzling screen or barn door, but also can be omitted setting shading piece.

Compared with prior art, the utility model lens module by by original whole glass lens by the two of two kinds of materials Part forms, it is ensured that eyeglass outer-diameter accuracy, and also it is more accurate with barrel cooperation, being not in that assembling is not in place asks Topic, to improve the assembling yield of product；Cooperate precision high, cooperation is more stable, improves the entirety of camera lens to a certain extent Performance.

Above-described is only the embodiments of the present invention, it should be noted here that for the ordinary skill of this field For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to it is practical Novel protection scope.
