It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, many technical details are proposed in order to make reader more fully understand the utility model.But even if without this
A little technical details and various changes and modifications based on the following respective embodiments, also may be implemented each claim of the utility model
Technical solution claimed.
The first embodiment of the utility model provides a kind of lens module 100, as shown in Figure 1, comprising:
Lens barrel 1 and the lens set 2 being contained in lens barrel 1, lens barrel 1 include the first barrel 11 for offering light hole, from the
One barrel 11 bends the second barrel 12 extended and the accommodating chamber surrounded by the first barrel 11 and the second barrel 12 towards image side direction
13, successively and common optical axis stacks and is arranged in accommodating chamber 13 from the lateral image side of object, lens set 2 includes close to first to lens set 2
First eyeglass 21 of wall 11, is additionally provided with anti-dazzling screen 3 between the first eyeglass 21 and lens barrel 1, anti-dazzling screen 3 is hollow and annular and its outside
Edge is embedded in the second barrel 12, and the first eyeglass 21 and lens barrel 1 are respectively from the image side of anti-dazzling screen 3 and object side against anti-dazzling screen 3.
The schematic diagram of lens module internal reflection light of anti-dazzling screen is not provided in lens module as shown in figure 4, in lens set
The reflected light of generation projects into image side after the reflection on the first barrel surface, to influence the matter of lens module imaging
Amount.
The utility model embodiment in terms of existing technologies, as shown in figure 5, by the first barrel 11 and first
Setting is in the anti-dazzling screen 3 of hollow and annular between eyeglass 21, cooperates and can absorb in lens set with the structure of lens barrel 1
Reflected light guarantee image quality so that reflected light be avoided to have an impact the image quality of lens module 100.And due to hiding
In second barrel 12 of the outer edge insertion lens barrel 1 of mating plate 3, the first eyeglass 21 and lens barrel 1 image side from anti-dazzling screen 3 and object respectively
Side is against anti-dazzling screen 3, so that lens module 100 is during the motion, anti-dazzling screen 3 is in the supporting of the second barrel 12, the first barrel
11 and first eyeglass 21 clamping action under relative displacement will not occur in lens module 100, it is ensured that lens module 100
Stability.
The realization details of present embodiment is specifically described below, the following contents is only for convenience of the realization for understanding offer
Details, rather than implement the necessary of this programme.
Anti-dazzling screen 3 includes the object side of neighbouring object side and the image side surface of neighbouring image side in present embodiment, and image side surface is thick
Matte.
Specifically, the image side surface that the anti-dazzling screen 3 in present embodiment is contacted with the first eyeglass 21 is rough surface, therefore
In the presence of the gap that can hold air pass-out between first eyeglass 21 and anti-dazzling screen 3, ensure that under hot and humid environment, lens module
It can be flowed out from gap after air expansion in 100, avoiding leads to mirror since air expansion, camera lens internal pressure increase
Piece deformation and 100 optical property of lens module are deteriorated, and ensure that the reliability of lens module 100.It should be noted that hiding
The object side that mating plate 3 is contacted with the first barrel 11 of lens barrel 1 may be alternatively provided as rough surface, increase the combination of anti-dazzling screen 3 and lens barrel 1
Power further increases the reliability of lens module 100.
It is noted that anti-dazzling screen 3 and lens barrel 1 are integrally formed in injection moulding process, using a face of anti-dazzling screen 3 as
The inner surface of first barrel 11 of lens barrel 1 makes anti-dazzling screen 3 and lens barrel 1 become an entirety.Rather than in 1 injection molding of lens barrel
Afterwards, then between lens barrel 1 and the first eyeglass 21 anti-dazzling screen 3 is placed, anti-dazzling screen 3 is not easy to send out lens module 100 during the motion
Raw relative displacement, it is ensured that the fastness of lens module 100.
Preferably, the image side surface of anti-dazzling screen 3 is covered with black powder coating.Black powder coating is absorbing in lens set 2
Reflection light aging fruit more preferably, it is ensured that anti-dazzling screen 3 absorption reflected light effect.Specifically, black powder coating is dumb light coating,
Low luster coating is one of coating, according to its paint film for light is in special angle reflection case (glossiness) differentiation,
Low luster coating overall effect is darker, and film is more plain after low luster coating brushing, also more has soft.Present embodiment gives black
A kind of material of color powder coating selects, it will be appreciated by a person skilled in the art that the coating of selection other materials is as screening
The scheme of mating plate coating also within the protection scope of present embodiment,
As shown in figure 3, the first eyeglass 21 includes for the first optical section 211 of imaging and around first in present embodiment
First peripheral portion 212 of optical section 211, the first peripheral portion 212 include the first surface 2121 being oppositely arranged with the first barrel 11,
Anti-dazzling screen 3 is arranged between first surface 2121 and the first barrel 11.
Specifically, as shown in Fig. 2, the first barrel 11 is equipped with the second surface 111 close to first surface 2121, the second table
Face 111 is equipped with the recessed portion 110 being recessed to object side, and 3 part of anti-dazzling screen is set in recessed portion 110.Such structure makes shading
Piece 3 can be partially or completely contained in recessed portion 110, will not be occupied the excessive space of lens module 100, be conducive to camera lens mould
The Miniaturization Design demand of group 100；And in 100 motion process of lens module, anti-dazzling screen 3 is acted in the clamping of recessed portion 110
Under relative displacement will not occur inside lens module 100, it is ensured that the stability of lens module 100.
It is noted that the recessed portion 110 in present embodiment is along perpendicular to optical axis OO` and far from the side of optical axis OO`
To extending in the second barrel 12.That is, the part-structure of anti-dazzling screen 3 is inserted into the second barrel 12, it is arranged so that
Anti-dazzling screen 3 the first barrel 11 and the second barrel 12 it is dual support under, further ensure being moved through in lens module 100
Inside lens module 100 relative displacement will not occur for anti-dazzling screen 3 in journey, thereby further ensure that the steady of lens module 100
It is qualitative.
It should be noted that the first barrel 11 in present embodiment Fig. 1 is arranged with the interval of first surface 2121.It ensure that
It, being capable of seam between anti-dazzling screen 3 and first surface 2121 after the expansion of air in lens module 100 under hot and humid environment
After being flowed out in gap, flowed out via the gap of the first barrel 11 and first surface 2121, to further ensure lens module 100
Reliability.Certainly, the first barrel 11 can also abut setting with first surface 2121, to avoid the first barrel 11 and the first table
The excessive moisture in gap between face 2121 is easily accessible in lens barrel 1, to influence the image quality of lens module.
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.
