Description

Lens construction

Technical field

The present invention relates to a kind of lens construction.

Background technology

Hand-held electronic device is more and more universal at present, and volume is more and more light, thin, short, little.In general; The configuration image extraction module has become the standard outfit on hand-held electronic device; For cooperating the also necessary miniaturization of the said image extraction module of design on its body; Except the assembling of eyeglass, also optical filter is arranged on the camera lens in the camera lens in the wherein said image extraction module, in order to the reduction space.The setting of present said optical filter; Be after lens set is loaded on the lens barrel inside of said camera lens; Need in the end the edge all around of an eyeglass sticks together fixing with colloid; And before said colloid setting is still uncured, said optical filter is arranged on said eyeglass rear, thereby said optical filter is fixed on the camera lens through the curing of said colloid.But, since the miniaturization of image extraction module, the fixing colloid of using that the eyeglass periphery in camera lens is provided with, and its colloid consumption must be restricted, to avoid the optical design function of the said eyeglass of the excessive influence of consumption.This restricted colloid consumption often causes tack strength not enough, can't effectively fix said optical filter, needs to see through the operation of mending glue again and fixes.Thereby make that processing procedure is complicated, cost improves.

Summary of the invention

In view of this, be necessary to provide a kind of lens construction, it is the interior optical filter of fixed lens easily and quickly.

The present invention provides a kind of lens construction, and it comprises a lens barrel, at least one eyeglass and an optical filter.Said lens barrel has a lens barrel room in order to ccontaining said eyeglass, and said lens barrel room has a semiclosed end and an openend.Said eyeglass is arranged on the position of contiguous said semiclosed end, and said optical filter is arranged on contiguous said openend position.The periphery of said optical filter has chamfering, forms a some glue space between the inwall of said chamfering and said lens barrel room.

Compare prior art; The point glue space that the chamfering of the said optical filter periphery of lens construction of the present invention and said lens barrel room inwall form; Can provide enough cementedly is provided with colloid; And near the openend of said lens barrel room, make some glue processing procedure convenience, the bonding of said optical filter when assembling firm, can effectively save man-hour with said camera lens.

Embodiment

To combine accompanying drawing that the present invention is done one below specifically introduces.

See also Fig. 1, the embodiment assembled sectional view of lens construction of the present invention, said lens construction 100 comprise a lens barrel 10, at least one eyeglass 20 and an optical filter 30.

Said lens barrel 10 has a lens barrel room 102 in order to ccontaining said eyeglass 20, and the cylindrical shell of said lens barrel room 102 is the right cylinder of a hollow, and the two ends of its cylindrical shell comprise a semiclosed end 104 and an openend 106 respectively.The central authorities of said semiclosed end 104 offer one and go into perforation 1042, saidly go into perforation 1042 usefulness so that light is injected in the lens barrel room 102 thus.Said openend 106 usefulness so that said eyeglass 20 insert thus in the said lens barrel room 102.Have external thread 108 setting on the outer edge surface of said lens barrel 10, said external thread 108 constitutes camera lens module in order to the screw-internal thread fit winding that has with lens mount (indicating among the figure).Said eyeglass 20 is after said openend 106 sets into said lens barrel room 102, with the position that is adjacent to said semiclosed end 104.30 of said optical filters set into said lens barrel room 102 from said openend 106 equally, and it is contiguous simultaneously in said openend 106 positions to be arranged on said eyeglass 20 rear ends.The semiclosed end 104 of said lens barrel room 102 and the internal height between the openend 106;

Eyeglass

20 or 20 groups of thickness of eyeglass of corresponding said lens construction 100 optical designs make 20 groups on said eyeglass 20 or eyeglass intactly be contained in said lens barrel room 102 inside.The miniaturization Design of said lens construction 100 makes 20 groups on said eyeglass 20 or eyeglass and said optical filter 30 be arranged at said lens barrel room 102 inside simultaneously.In this embodiment, the eyeglass of said optical design has three eyeglasses 20 for 20 groups.Said three eyeglasses 20 are arranged in the said lens barrel 10 said eyeglass 20 through the openend 106 of said lens barrel room 102, and are arranged to said openend 106 places by the semiclosed end 104 of said lens barrel room 102.And then said eyeglass 20 rear ends are provided with said optical filter 30 in said openend 106 places.The periphery 302 of said optical filter 30 is relative with the inwall 1022 of said lens barrel room 102, and has a chamfering 304.Said chamfering 304 forms a dip plane on the wall of said periphery 302, said chamfering 304 dip plane from said optical filter 30 inboard towards said semiclosed end 104 towards the outer tilt of said relatively openend 106.That is, said chamfering 304 dip plane make the external profile diameter D of the external profile diameter d of said optical filter 30 lateral surfaces (towards said openend 106 places) less than its medial surface (towards said semiclosed end 104 places).1022 of the inwalls of said chamfering 304 dip plane and relative said lens barrel room 102 form a some glue space S (shown in the partial enlarged drawing of Fig. 2); Said some glue space S is to be the space of a grooved; Colloid (indicating among the figure) setting is binded in order to provide in said grooved space, makes said optical filter 30 bind openend 106 places of being fixed in said lens barrel 10.Said some glue space S increases the contact area of said optical filter 30 and said lens barrel room 102 inwalls 1022, makes the bonding of said optical filter 30 more firm.Said some glue space S is formed on openend 106 places of said lens barrel room 102; Make things convenient for the some glue processing procedure running of point gum machine; Can once accomplish the some glue operation (like Fig. 3 institute sign) that whole circle binds colloid G around the periphery of said optical filter 30, need not remake any benefit glue and operate.Said some glue space S can be held an amount of bonding colloid G, can not cause excessive glue situation and need the artificial disappearance of wiping away of inserting, and reaches effective good effective utilization of saving man-hour.

To sum up; The periphery of the said optical filter 30 of lens construction of the present invention has chamfering 304 and is provided with; The said some glue space S that the inwall 1022 of said chamfering 304 and said lens barrel room 102 forms; The processing procedure running of the setting of convenient said bonding colloid G and some glue, thus can make the bonding of said optical filter 30 firm, and can effectively save man-hour.

In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, these all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
