Seek the technical solution of protection.
The first embodiment of the utility model is related to a kind of lens module 100, as shown in Figures 1 to 3, comprising: lens barrel 10,
The lens barrel 10, which encloses, to be set to form accommodating space 20, and the light with the lens barrel 10 assembling cooperation is contained in the accommodating space 20
Component 11 and the flexible elasticity pressure holding piece 12 along the direction optical axis OO' are learned, the elasticity pressure holding piece 12 is supported described
On optical module 11.
The utility model embodiment in terms of existing technologies, since elastic pressure holding piece 12 is along the direction optical axis OO'
It is upper that there is elasticity, and elastic pressure holding piece 12 supports on optical module 11, therefore, optical module 11 is along the direction optical axis OO'
It is acted on by certain elastic force, when effect of the lens module 100 due to falling or collide by external force, elastic 12 energy of pressure holding piece
Enough play the role of buffering, to reduce the damage of optical module 11, improves the reliability of lens module 100.
Specifically, optical module 11 can be for eyeglass, shading piece etc., and the optical module being contained in accommodating space 20
11 quantity can be to be multiple, and elastic pressure holding piece 12 can be set between two optical modules 11, also can be set in lens barrel
10 and between the optical module 11 of object side, or be arranged between optical module 11 and pressure ring 13, and elastic pressure holding piece
12 at least support on an optical module 11 wherein.When effect of the lens module 100 by external force, the effect of power can lead to
It travels on elastic pressure holding piece 12 after the optical module supported layer by layer, finally gradually subtracts via the buffer function of elastic pressure holding piece 12
It is small, to play the role of protecting optical module 11.
In present embodiment, optical module 11 is arranged in the object side of elastic pressure holding piece 12, and elastic pressure holding piece 12 is from optics group
The image side of part 11 supports optical module 11, and the image side of elastic pressure holding piece 12 is provided with pressure ring 13,13 own elasticity pressure holding piece 12 of pressure ring
Image side support elastic pressure holding piece 12.Since pressure ring 13 is arranged in the image side of elastic pressure holding piece 12, all optical modules are respectively provided with
In the object side of elastic pressure holding piece 12, therefore, being packed into elastic pressure holding piece 12 will not influence the loading of optical module 11, optical module 11
It still is able to without departing substantially from original position, so that elastic pressure holding piece 12 can be before having substantially no effect on optical module installation
It puts, buffer function is provided, improve the reliability of lens module 100, meanwhile, it does not need to do lens barrel 10 any improvement yet,
With cost advantage.
In present embodiment, elastic pressure holding piece 12 includes annular brace portion 121, and is prolonged from the bending of annular brace portion 121
The elastic portion 122 stretched, at least one of annular brace portion 121 and elastic portion 122 support on optical module 11.Since elasticity is pressed
Gripping member 12 includes annular brace portion 121, and annular brace portion 121 can be in loading lens barrel 10 easily, firm, and annular branch
Support part 121 plays a part of to support and fix to elastic portion 122, and therefore, elastic portion 122 more convenient, firm can be fixed on
In lens barrel 10.
It is understood that elastic pressure holding piece 12 can also only include at least one elastic portion 122, without annular
Support portion 121, elastic portion 122 directly press in lens barrel 10.
Further, one end of elastic portion 122 is connected with annular brace portion 121, the other end of elastic portion 122 is free end

Metal has characteristic with strong elasticity, therefore using the elastic portion 122 and annular brace portion 121 of metal material, has good bullet
Property, and structural reliability is high, is hardly damaged, meanwhile, integrated punching is made with advantage easy to process, at low cost.
Preferably, elastic portion 122 is equipped with multiple, and multiple elastic portions 122 surround the optical axis OO' of lens module 100 at equal intervals
Setting.In present embodiment, the quantity of elastic portion 122 is eight, and eight elastic portions 122 surround the optical axis OO' of lens module 100
It is arranged at equal intervals.Compared to not being the elastic portion being arranged at equal intervals, multiple elastic portions 122 surround what optical axis OO' was arranged at equal intervals
Mode supports the optical module 11 on elastic pressure holding piece 12 by more uniform resist force, therefore optical module 11 is same
Axis Du Genggao, optical property are more preferable.
In addition, there are two types of disposing ways for elastic pressure holding piece, one is annular brace portions 121 close to object side, and elastic portion 122 is leaned on
Nearly image side；Another kind is annular brace portion 121 close to image side, and elastic portion 122 is close to object side.It is the first in present embodiment,
I.e. annular brace portion 121 close to object side and supports on optical module 11, and elastic portion 122 is close to image side and supports in pressure ring 13
On.
The second embodiment of the utility model is related to another lens module, second embodiment and first embodiment
It is roughly the same, it is elastic pressure holding piece 200 in place of the main distinction, as shown in Figure 4: in the first embodiment, elastic portion 122
One end is connected with annular brace portion 121, the other end of elastic portion 122 is free end 122a, annular brace portion 121 and elastic portion
At least one of 122 free end 122a is supported on optical module 11.And in the utility model second embodiment, elasticity
The both ends in portion 222 are connected with annular brace portion 221, the central location of elastic portion 222 is arched upward for support division 222a, annular brace portion
At least one of 221 and support division 222a support on optical module 11.In addition, it will be understood by those skilled in the art that this reality
With novel second embodiment and first embodiment technical effect having the same, details are not described herein again.
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
And range.
