Description
Technical field
The present invention relates to a kind of lens and camera lens module, it can be applicable to system fields such as camera, video camera.
Background technology
Along with Development of Multimedia Technology, camera systems such as digital camera, video camera more and more are consumers in general's favor.Existing camera system such as mobile phone digital camera, its camera lens module generally are made up of lens barrel and some lens of being housed in the lens barrel.In the entirety of lens package process, tabling is concentric to guarantee in twos with eyeglass usually.
As shown in Figure 1, common camera lens module comprises lens barrel 30, and is housed in first lens 31, second lens 32 and spacing washer 33 in this lens barrel 30.The edge of these first lens 31 is extended with circular protrusion 310 along its optical axis direction, and this circular protrusion 310 is close to lens barrel 30 inwalls and is surrounded a receiving space, in second lens 32 are housed in.Described spacing washer 33 is arranged between first lens 31 and second lens 32.
In assembling process, the receiving space of first lens 31 of earlier second lens 32 being packed into is usually organized chimeric first, second good lens 31,32 in the lump and is gone into lens barrel 30 so that first, second lens 31,32 are chimeric mutually.Yet owing to this circular protrusion 310 is to be extended along its optical axis direction by the edge of first lens 31 to form, in these first lens 31 were assembled into process in the lens barrel 30, this circular protrusion 310 can contact with lens barrel 30 sidewalls and produce acting force.Therefore, the circularity of lens barrel 30 and size will be pushed circular protrusion 310, and make circular protrusion 310 that deformation take place, and this circular protrusion 310 will further push second lens 32, cause second lens 32 skew to take place and then influence concentricity because of stressed.
In view of this, be necessary to provide a kind of lens, it can guarantee higher concentricity with the eyeglass chimeric with it in the process of organizing lens barrel.
Summary of the invention
Below will a kind of lens be described with specific embodiment, it can guarantee higher concentricity with the eyeglass chimeric with it in the process of organizing lens barrel.
A kind of lens, it comprises the optical region that is used to realize optical function and links to each other with this optical region and around the ring-type mechanism zone of this optical region, the anchor ring in this ring-type mechanism zone is provided with a circular protrusion along this lens axis direction extension, this circular protrusion distributes around lens axis and surrounds a receiving space, the anchor ring that this circular protrusion and the surface of contact in this ring-type mechanism zone are positioned at ring-type mechanism zone with and with the edge of this anchor ring mutually across a certain distance.
A kind of lens module, it comprises one first lens, one second lens and a lens barrel.These first lens comprise the optical region that is used to realize optical function and link to each other with this optical region and around the ring-type mechanism zone of this optical region.The anchor ring in this ring-type mechanism zone is provided with a circular protrusion along this lens axis direction extension.This circular protrusion distributes around lens axis and surrounds a receiving space, the anchor ring that this circular protrusion and the surface of contact in this ring-type mechanism zone are positioned at ring-type mechanism zone with and with the edge of this anchor ring mutually across a certain distance.These second lens are housed in the receiving space that circular protrusion surrounded of first lens.In this lens barrel is housed in these first lens and second lens.
Compared with prior art, the anchor ring that the circular protrusion of described lens and lens module and the surface of contact in its ring-type mechanism zone are positioned at ring-type mechanism zone with and with the edge of this anchor ring mutually across a certain distance, thereby these lens are organized in the process of lens barrel, the side edge in lens barrel inwall and ring-type mechanism zone is touched and is kept above-mentioned spacing with circular protrusion, thereby can avoid circular protrusion deformation to take place, and then can guarantee higher concentricity with the eyeglass chimeric with it because of the acting force that is subjected to the lens barrel inwall.

Fig. 3 is the camera lens modular structure synoptic diagram that second embodiment of the invention provides.
Embodiment
Below with reference to accompanying drawing the embodiment of the invention is described in further detail.
Referring to Fig. 2, the lens 10 that first embodiment of the invention provided comprise optical region 11 and mechanism zone 12.
This optical region 11 is used for for light by to realize the optical function of lens 10, as convergence function or disperse function etc.
This mechanism zone 12 is used to support this optical region 11.This mechanism zone 12 is an annular section, and it distributes around optical region 11.This mechanism zone 12 comprises first anchor ring 121, second anchor ring 122 and side 123.This first anchor ring 121 is relative with second anchor ring 122, the side edge of this side 123 and first anchor ring 121 and second anchor ring 122, and between first anchor ring 121 and second anchor ring 122.In the present embodiment, this mechanism zone 12 is circular.
This first anchor ring 121 is provided with a circular protrusion 124 that extends along these lens 10 optical axises (among the figure shown in the dot-and-dash line) direction.This circular protrusion 124 surrounds a receiving space 126.This circular protrusion 124 and first anchor ring 121 join, the surface of contact of the two be positioned at first anchor ring 121 inner and not with the side edge of first anchor ring 121, promptly with the edge of first anchor ring 121 mutually across a certain distance, thereby do not join with side 123.In the present embodiment, this circular protrusion 124 surrounds a cylinder around the optical axis continuous distribution of lens 10, and the internal diameter r1 of this cylinder is greater than the internal diameter R in this ring-type mechanism zone
1, the external diameter r2 of this cylindric projection is less than the external diameter R in this ring-type mechanism zone
2
Referring to Fig. 3, second embodiment of the invention also provides a kind of camera lens module 20 with lens 10.This camera lens module 20 comprises lens barrel 21, lens 10 and lens 22.
This lens barrel 21 comprises a cylinder 210 and the lens barrel front end 212 that is positioned at cylinder 210 1 ends.
These lens 10 are housed in cylinder 210 inside of lens barrel 21, and second anchor ring 122 of these lens 10 is towards this lens barrel front end 212.The side 123 of these lens 10 contacts with lens barrel 21 inwalls, and the circular protrusion 124 of the inwall of this lens barrel 21 and lens 10 keeps a determining deviation d.
These lens 22 are housed in the receiving space 126 that circular protrusion 124 surrounded.Preferably, also be provided with a spacing washer 23 between these lens 22 and the lens 10.
The lens 10 that present embodiment provided, it is being gone into by group in the process of lens barrel 20, lens barrel 20 inwalls contact with the side 123 at first anchor ring, 121 edges, and keep a determining deviation d with circular protrusion 124, thereby can avoid circular protrusion 124 deformation to take place because of the acting force that is subjected to lens barrel 20 inwalls, therefore can not cause extruding, thereby can guarantee higher concentricity with the eyeglass chimeric with it to lens 22.
Need to prove, the circular protrusion of being showed among Fig. 2 and Fig. 3 124 around the optical axis continuous distribution of lens 10 on first anchor ring 121, but, this circular protrusion 124 also can change to the projection around the optical axis Discrete Distribution of lens 10, as long as the projection of this Discrete Distribution can play the fixing effect to lens 22, to guarantee lens 10 and lens 22 concentric getting final product.
In addition, those skilled in the art also can do other and change in spirit of the present invention, as the shape of suitable change circular protrusion and distribution mode etc., as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
