A little technical details and various changes and modifications based on the following respective embodiments, can also realize each claim of the utility model
Technical solution claimed.
The first embodiment of the utility model is related to a kind of lens assembly 100, as depicted in figs. 1 and 2, including has receipts
Hold the lens barrel 11 in space 10, be arranged in receiving space 10 and at least has there are one the lens set 12 of eyeglass, is set to lens set
Lens set 12 is fixed on receiving space 10 by the pressure ring 13 of 12 image sides and the optical filter 14 for being set to 11 image side of lens barrel, pressure ring 13
Interior, pressure ring 13 includes the object side 131 close to object side, the image side surface 132 close to image side and is separately connected object side 131 and picture
The joint face 133 of side 132.Lens assembly 100 further includes the shading piece 15 for being fixed on 13 image side surface 132 of pressure ring, shading piece 15
Extend from pressure ring 13 towards the directions optical axis OO ', the illumination that the shading piece 15 prevention is reflected from optical filter 14 is incident upon the company of pressure ring 13
In junction 133.
In present embodiment, a shading piece extended towards the directions optical axis OO ' is set on the image side surface 132 of pressure ring 13
15, the light reflected from the optical filter 14 in image side direction is absorbed by the shading piece 15, in addition, also avoiding the reflected light
It is emitted directly toward the joint face 133 of pressure ring 15 or image side surface 132 and secondary reflection occurs and forms veiling glare, thus greatly weaken
Veiling glare inside lens assembly 100, improves the whole image quality of lens assembly 100.
It is noted that the shading piece 15 is stamped and formed out, the shading piece on the image side surface 132 of pressure ring 13 is set
15 can not only absorb the light reflected from optical filter 14, moreover it is possible to which absorption is incident upon the shading from other directions or structure
Light on part 15.
In addition, as shown in Figure 1, the anti-dazzling screen 15 extends from the image side surface 132 of pressure ring 13 towards the directions optical axis OO ' and in center
Region surrounds a through-hole as loophole, substitutes light transmission be arranged on pressure ring originally, with particular optical design parameter
Hole, so that the molding of pressure ring 13 is more simple.
Preferably, as shown in Fig. 2, in the present embodiment, the image side surface 132 of pressure ring 13 includes further the first connection
Portion 132a and second connecting portion 132b, specifically, first connecting portion 132a is from joint face 133 away from the side of optical axis OO '
To horizontal extension, second connecting portion 132b extends vertically from first connecting portion 132a towards image side direction, so so that first connects
Socket part 132a and second connecting portion 132b form a groove 134 towards image side, which is fixed on the groove 134
It is interior.
It is understood that first connecting portion 132a, the second connecting portion 132b of 13 image side surface 132 of above-mentioned pressure ring can be with
There is the combination of other extending directions, and form different groove structure, here without enumerating, it should be noted that
Using the combination of any one extending direction, compared with the prior art for, the shading piece 15 that is arranged in the groove can be good
Good reflection veiling glare of the absorption from image side.
In addition to this, as shown in Fig. 2, the image side surface 132 of pressure ring 13 further includes from second connecting portion 132b away from light
The horizontal-extending third interconnecting piece 132c in direction of axis OO ', the side from third interconnecting piece 132c towards object side simultaneously far from optical axis OO '
To tilt the 4th interconnecting piece 132d extended, from the 4th interconnecting piece 132d away from the direction of optical axis OO ' horizontal-extending the
Five interconnecting piece 132e.So set, the internal face of the 4th interconnecting piece 132d, the 5th interconnecting piece 132e and lens barrel 11 can be utilized
A glue groove is surrounded, and glue for dispensing glue is accommodated using the glue groove, preferably pressure ring 13 to be fixed on the inner wall of lens barrel 11.
In the present embodiment, in order to enable shading piece 15 can preferably be absorbed towards image side and preferably from picture
Shading piece 15 is preferably arranged to horizontality by the reflected light of side direction.
Also, due to by glue be fixed in the way of it is relatively simple, cost is also low, so screening in the present embodiment
Light part 15 is fixed on pressure ring 13 by glue, this kind of glue can be common glue or viscose glue etc., it is to be understood that
It can also select other modes that shading piece 15 is made to be fixed on pressure ring 13.In addition, since anti-dazzling screen is to be commonly used in lens assembly
Light screening material, extinction effect is good, thickness is thin, be easy obtain and it is of low cost, be extraordinary light screening material, therefore,
In present embodiment, shading piece 15 specifically uses anti-dazzling screen, and certainly, which can also be other common lightproof materials
Material, is not described in detail here.
In addition, due to the cost of plastic material is low, light weight and obtain be relatively easy to, in present embodiment
Pressure ring 13 is preferably plastic cement material.It is understood that the pressure ring 13 can also be other materials.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific implementation of the utility model
Example, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit of the utility model
