Abstract
The invention provides a lens structure, which comprises a lens barrel and at least one lens, wherein the lens barrel is provided with a lens barrel chamber for accommodating the lens and a barrel body encircled into the lens barrel chamber; the lens is arranged in the lens barrel chamber and is spaced from the inner wall of the barrel body by a gap; the barrel body is provided with a semi-enclosed end; the barrel body is provided with a plurality of through groove holes which pass through the barrel body and are communicated with the lens barrel chamber; and the plurality of through groove holes are formed close to the semi-enclosed end and are aligned with the lens on the inner side of the semi-enclosed end. By adopting the lens structure, the lens on the inner side of the semi-enclosed end can be eccentrically adjusted through the plurality of through groove holes in the assembling process.
Description
Technical field
The present invention relates to a kind of lens construction.
Background technology
Portable electric device is more and more universal at present.In general, the configuration taken module has become the standard outfit on portable electric device, for promoting the yield of taken module, must promote the assembly precision of the eyeglass in the camera lens in the taken module, but the eccentricity of glasses lens adjusting gear is not set between eyeglass in the camera lens of taken module and the lens barrel, thereby makes to the eccentric correction of eyeglass comparatively difficult.
Summary of the invention
In view of this, be necessary to provide a kind of lens construction, it can make things convenient for, the off-centre of the eyeglass in the rapid adjustment camera lens.
The invention provides a kind of lens construction, it comprises a lens barrel and at least one eyeglass.Described lens barrel has one in order to the lens barrel room of ccontaining described eyeglass and surround the cylindrical shell of described lens barrel room.Described eyeglass is arranged in the described lens barrel room, and and the inwall of described cylindrical shell between have a gap.Described cylindrical shell has a semiclosed end.Offer a plurality of perforation slotted eyes that run through this cylindrical shell and be interconnected on the described cylindrical shell with described lens barrel room.Described a plurality of perforation slotted eye is arranged on the position of contiguous described semiclosed end, and aligns mutually with the eyeglass that is arranged on this semiclosed end inboard.Thereby make camera lens in assembling process, can come the eyeglass of this semiclosed end inboard is carried out off-centre adjustment by described a plurality of perforation slotted eyes.

Embodiment
Below in conjunction with accompanying drawing the present invention being done one specifically introduces.
See also Fig. 1 to Fig. 4, lens construction 100 provided by the invention comprises that a lens barrel 10 and at least one are contained in the eyeglass 20 in the described lens barrel 10.
Described lens barrel 10 comprises a cylindrical shell 104 that reaches around described lens barrel room 102 in order to the lens barrel room 102 of ccontaining described eyeglass 20.Described cylindrical shell 104 is the right cylinder of a hollow, and it has a semiclosed end 106 and an openend 108.The central authorities of described semiclosed end 106 offer one and go into perforation 110 usefulness so that light is gone into thus injects in the perforation 110 in the described lens barrel room 102.Described openend 108 usefulness are so that described eyeglass 20 is inserted described lens barrel room 102 interior (as shown in Figure 4) thus.Described cylindrical shell 104 outer edge surfaces are provided with the screw thread 104a in order to use with lens mount (figure do not show) winding.Described screw thread 104a only is arranged on the subregion of described cylindrical shell 104 on outer edge surface, leaves the part that described screw thread 104a is not set in the position of the semiclosed end 106 of contiguous described cylindrical shell.Described cylindrical shell 104 offers a plurality of a plurality of slotted eye 104b that run through described cylindrical shell 104 and be interconnected with described lens barrel room 102 at its excircle.Described a plurality of slotted eye 104b is arranged on the position of contiguous described semiclosed end 106, and aligns mutually with the eyeglass 20 that is arranged on these semiclosed end 106 inboards, to pass the position that these a plurality of slotted eye 104b regulate described eyeglass 20 relative cylindrical shells 104 by adjustment means.In the present embodiment, be formed with four slotted eye 104b on the excircle of described cylindrical shell 104, described four slotted eye 104b are evenly distributed in the same circle ring area on the described cylindrical shell 104 at interval, and interval 90 is spent in twos.
Described eyeglass 20 is arranged in the described lens barrel room 102, and is positioned at the inboard of described semiclosed end 106.The sidewall of described eyeglass 20 aligns mutually with a plurality of slotted eye 104b of described cylindrical shell 104.The radius of described eyeglass 20 is slightly less than the internal diameter of the lens barrel room 102 of described cylindrical shell 104, thereby between the madial wall of the sidewall of described eyeglass 20 and described cylindrical shell 104, form a gap 30 so that described eyeglass 20 can be done microspur moves in described cylindrical shell 104, thereby adjust the position of the described relatively cylindrical shell 104 of eyeglass 20.
When the assembling of eyeglass in the camera lens 20 need be adjusted, whether detect eyeglass 20 by the eccentricity of glasses lens detection machine eccentric, if it is eccentric that eyeglass 20 exists, then make the adjustment instrument pass described a plurality of slotted eye 104b described eyeglass 20 is carried out the adjustment of all directions, and in the process of adjusting, monitor adjustment process in real time by the eccentricity of glasses lens detection machine, just can be after described eyeglass 20 is adjusted to the precalculated position by colloid (UV glue) is imported from described a plurality of slotted eye 104b, colloid is filled in the gap 30 of 102 of these eyeglass 20 lateral walls and lens barrel rooms, thereby described eyeglass 20 is fixed on suitable positions in the lens barrel 10.
To sum up, the lens construction of embodiment of the present invention comprises: described lens barrel 10 is by being provided with described a plurality of slotted eye 104b, thereby conveniently finish the off-centre adjustment that is placed in eyeglass 20 in the described lens barrel 10 lens barrel rooms 102, and can finish the location of described eyeglass 20 in the lump, can make the yield lifting of assembling and reduce its cost.
Be noted that above-mentioned embodiment only is better embodiment of the present invention, those skilled in the art also can do other variation in spirit of the present invention.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.
