Abstract
The invention provides a lens module which comprises an inner lens cone, an outer lens cone, a first lens set and a second lens set. The outer lens cone sequentially contains the inner lens cone and the first lens set from the object side to the image side. The second lens set is contained in the inner lens cone. The diameter of each lens in the first lens set is larger than that of each lens in the second lens set. The lens module has high concentricity.
Description
Technical field
The present invention relates to camera lens module field, relate in particular to a kind of camera lens module that comprises the lens of different-diameter.
Background technology
Along with electronic product multifunction day by day, the camera lens module is used widely in consumption electronic products such as mobile phone, notebook computer, digital camera, personal digital assistant.People hope that also electronic product has increasingly high image quality when pursuing multifunction.
Camera lens module commonly used generally includes a lens barrel and a plurality of lens that are contained in this lens barrel.Each lens is fixed in this lens barrel inwall with gluing process respectively.This causes lens when assembling, to be prone to depart from, and produces concentricity between the lens, must influence the image quality of assembling rear lens module.In addition, as far as portable type electronic product, for meeting the needs of miniaturization, its diameter is made more and smaller and more exquisitely, and this makes the maximum gauge of the lens that same lens barrel can be accommodated be restricted.Yet high image quality needs correspondence that sensing elements such as major diameter charge coupled cell or cmos device are set.Therefore, be necessary to provide a kind of camera lens module of lens that has higher concentricity and can accommodate different-diameter to improve the image quality of electronic product.
Summary of the invention
Below be a kind of camera lens module that has higher concentricity and contain the lens of different-diameter of example explanation with embodiment.
This camera lens module comprises inner lens cone, outer lens barrel, connecting cylinder, first lens combination and second lens combination.Should extremely offer first containing cavity and second containing cavity of mutual perforation successively from the thing side in the outer lens barrel as side.The internal diameter of this first containing cavity is less than the internal diameter of this second containing cavity.The part of this inner lens cone is fixed in this first containing cavity through screw-threaded engagement.Another part of this inner lens cone stretches in this second containing cavity.This connecting cylinder and this inner lens cone structure that is formed in one.The external diameter of this connecting cylinder is greater than the maximum outside diameter of this inner lens cone.This connecting cylinder is housed in this second containing cavity.This connecting cylinder comprises a sidewall and a roof.This sidewall contacts with the inwall of this second containing cavity.This roof extends to be connected with the end face of this inner lens cone from the optical axis direction of this sidewall towards this camera lens module.This first lens combination is contained in this connecting cylinder.This second lens combination is contained in this inner lens cone.The diameter of each lens is greater than the diameter of each lens in this second lens combination in this first lens combination.
The lens barrel module of present technique scheme adopts the less inner lens cone of diameter to accommodate the second less lens combination of diameter; Adopt the bigger outer lens barrel of diameter to accommodate the first bigger lens combination of diameter; And the inner lens cone that will contain second lens combination is contained in the outer lens barrel; Improve the concentricity between the lens thus, the maximum gauge of the lens that the increase lens barrel can be accommodated.
Description of drawings
Fig. 1 is the synoptic diagram of the camera lens module that provides of present technique scheme first embodiment.
Fig. 2 is the synoptic diagram of the camera lens module that provides of present technique scheme second embodiment.
Fig. 3 is the synoptic diagram of the camera lens module that provides of present technique scheme the 3rd embodiment.
Embodiment
Below in conjunction with embodiment and accompanying drawing the camera lens module that the present technique scheme provides is elaborated.
Referring to Fig. 1, the camera lens module 100 that present technique scheme first embodiment provides comprises outer lens barrel 10, inner lens cone 20, the first lens combination 40, the second lens combination 30, spaced ring 50 and optical filter 60.Inner lens cone 20, the first lens combination 40 and optical filter 60 from the thing side to as side successively outside optical axis is contained in the lens barrel 10.The diameter of lens is greater than the diameter of the lens of second lens combination 30 in first lens combination 40.
In the present embodiment, first lens combination 40 comprises one first lens.These lens are fixed in outer lens barrel 10 inwalls with a glue or other modes, and contact with the end face of inner lens cone 20.In addition, the number of first lens is not limited to one.First lens combination 40 also can be provided with away from inner lens cone 20.
In the present embodiment; Adopt the less inner lens cone 20 of diameter to accommodate second lens combination 30; Adopt the bigger outer lens barrel 10 of diameter to accommodate first lens combination 40, and the inner lens cone 20 that will contain first lens combination 30 is contained in the outer lens barrel 10, makes the light shaft coaxle of each lens thus; Improve the concentricity between the lens, the maximum gauge of the lens that the increase lens barrel can be accommodated.
Referring to Fig. 2, to compare with camera lens module 100, the camera lens module 200 that present technique scheme second embodiment provides further comprises connecting cylinder 270.Connecting cylinder 270 is fixed in the inwall of outer lens barrel 210.First lens combination 240 is contained in the connecting cylinder 270 with optical filter 260.Connecting cylinder 270 can increase by first lens combination 240 and be fixed in the stability in the outer lens barrel 210 with optical filter 260.
Referring to Fig. 3, to compare with camera lens module 200, the connecting cylinder 370 of the camera lens module 300 that present technique scheme the 3rd embodiment provides is integrally formed with inner lens cone 320.Connecting cylinder 370 comprises sidewall 371 and the roof 372 that links to each other with sidewall 371.Sidewall 371 is fixed in the inwall of outer lens barrel 310.Roof 372 links to each other with the end face of inner lens cone 320, and is provided with the through hole 3722 that communicates with inner lens cone 320.Roof 372 offers accepting groove 3721 from its outside surface to its inside; This accepting groove 3721 is used for holding the material bits that process that inner lens cone 320 screws in outer lens barrel 310 produces because of the phase mutual friction, thereby prevents that the material that inner lens cone 320 produces when screwing in outer lens barrel 310 from considering pollution first lens combination 340 to be worth doing.Optical filter 360 is directly fixed on the inwall of outer lens barrel 310, and near first lens combination 340.In addition, connecting cylinder 370 can be provided with separately, and its roof 372 contacts with the end face of inner lens cone 320.
More than the camera lens module of present technique scheme is described in detail, but can not be interpreted as it is restriction to the present technique plan plot.For the person of ordinary skill of the art, can make other various corresponding changes and distortion, and all these change the protection domain that all should belong to the application's claim with distortion according to the technical conceive of present technique scheme.
