Attached drawing herein is incorporated into specification and forms the part of this specification, shows and meets the utility model
Embodiment, and for explaining the principle of the utility model together with specification.
Specific embodiment
Below by specific embodiment and with reference to attached drawing, the utility model is further described in detail.
As shown in Figs. 1-3, the utility model embodiment provides a kind of lens assembly, which can be applied to electronics
In equipment, camera function is can be used to implement, which includes：
Lens barrel 100, lens barrel 100 have loophole 110 and receiving space 120, and loophole 110 is connected with receiving space 120
It is logical.Lens barrel 100 could be provided as cylinder, and loophole 110 enters for light in receiving space 120, and axis direction can be put down
Row is in the axis direction of lens barrel 100.Specifically, loophole 110 usually could be provided as one, can be located at lens barrel 100
Center position, and circular hole may be used in the loophole 110, and size is flexibly set according to actual demand.
Eyeglass 200, eyeglass 200 are accommodated in receiving space 120.It, can be in order to promote the imaging performance of lens assembly
Eyeglass 200 is set as multiple, multiple eyeglasses 200 are stacked gradually along the axis direction of loophole 110.For the ease of retouching
It states, the first eyeglass 200a can be defined as farthest away from one of loophole 110 by each eyeglass 200；
Barn door 300, the barn door 300 are accommodated in receiving space 120, inside there is unthreaded hole 310, the light excessively
Hole 310 is connected with the loophole 110 on lens barrel 100, at this point, loophole 110 can be surrounded by crossing the hole wall 311 of unthreaded hole 310
Center line forms annular hole wall；In order to promote shaded effect, barn door 300 can be set as multiple；
Punching press anti-dazzling screen 400, the punching press anti-dazzling screen 400 are set between barn door 300 and eyeglass 200, inside have
Light hole 410, the light hole 410 are connected with the loophole 110 on lens barrel 100, and punching press anti-dazzling screen 400 is relative to barn door
300 stretch out to the direction of the center line close to loophole 110.That is, the hole wall of the light hole 410 of punching press anti-dazzling screen 400
The distance between center line of loophole 110, less than the hole wall 311 for crossing unthreaded hole 310 and the loophole 110 of barn door 300
The distance between center line.The punching press anti-dazzling screen 400 may be used Sheet Metal Forming Technology and be made.
The lens assembly that the utility model embodiment provides increases punching press anti-dazzling screen 400, and 400 phase of punching press anti-dazzling screen
Barn door 300 to the direction of the center line close to loophole 110 is stretched out, therefore enters a part of stray light of lens assembly
To be absorbed first by punching press anti-dazzling screen 400, the absorptivity of this punching press anti-dazzling screen 400 than barn door 300 absorptivity bigger,
That is the photo absorption performance of punching press anti-dazzling screen 400 is more excellent than the photo absorption performance of barn door 300, therefore punching press anti-dazzling screen 400 can absorb
More stray lights so that the image quality of lens assembly is promoted.Certainly, barn door 300 and punching press anti-dazzling screen 400 can be with
Stray light is absorbed simultaneously, the image quality of lens assembly is further promoted with this.
The first eyeglass 200a will be defined as farthest away from one of loophole 110 above, due to through the first eyeglass 200a's
Light beam is most, at this point, punching press anti-dazzling screen 400 and barn door 300 may be contained within the first eyeglass 200a away from aforementioned loophole 110
Side, can absorb stray light to greatest extent, improve image quality.
Further, as shown in Fig. 2, above-mentioned first eyeglass 200a can include the main part 210 and mounting portion that are connected
220, the effect of this main part 210 is passed through for light, and the effect of mounting portion 220 is between realization body portion 210 and lens barrel 100
Location and installation.The edge that this mounting portion 220 can surround main part 210 is set, and main part 210 can be relative to mounting portion
220 protrusions, specifically, main part 210 can be protruded relative to mounting portion 220 to the direction far from loophole 110.Mounting portion
220 could be provided as plane towards the surface of punching press anti-dazzling screen 400, and punching press anti-dazzling screen 400 is close to the center line of loophole 110
Side can then extend to the joint of main part 210 and mounting portion 220.At this point, punching press anti-dazzling screen 400 can be close proximity to
The center line of loophole 110, and then larger extinction face is formed, to absorb more stray lights.
In a kind of optional embodiment, above-mentioned lens assembly can also include auxiliary anti-dazzling screen 500, the auxiliary anti-dazzling screen
500 are accommodated in receiving space 120, and anti-dazzling screen 500 is assisted to be in contact with eyeglass 200.Specifically, the auxiliary anti-dazzling screen
500 could be provided as it is multiple, it is each to assist anti-dazzling screen 500 that be in contact from different eyeglasses 200, to promote auxiliary anti-dazzling screen
500 shaded effect.The thickness of punching press anti-dazzling screen 400 can be more than the thickness of auxiliary anti-dazzling screen 500, so that punching press anti-dazzling screen
400 thickness increased, and then absorb more stray lights.
Optionally, barn door 300 can be circular ring structure, cross unthreaded hole 310 can be cylindrical hole, conical bore or other
The hole of shape, also, the axis for crossing unthreaded hole 310 can be parallel with the axial direction of loophole 110.In order to simplify lens assembly
The hole wall 311 for crossing unthreaded hole 310 can be set as cylindrical surface, and the center line of the axis on the cylindrical surface and loophole 110 by structure
It is parallel.
Annular anti-dazzling screen may be used in above-mentioned punching press anti-dazzling screen 400, and the punching press anti-dazzling screen 400 is around loophole 110
Center line is set.At this point, the size of punching press anti-dazzling screen 400 increased, it can be in the side of the center line around loophole 110
The stray light in more direction is absorbed upwards so that the image quality higher of lens assembly.
Since plastic material is flexible material, barn door 300 can be set as plastic cement barn door so that barn door
It can deform after 300 compressions, and then apply reaction force to each eyeglass 200 so that each eyeglass 200 has in lens barrel 100
There is higher structural stability.In addition, in order to further enhance the absorptance of barn door 300, when selecting punching press anti-dazzling screen 400
Metal anti-dazzling screen can be selected.Metal material is easier to absorb light than plastic material, so the punching press anti-dazzling screen 400 of metal material compares
The anti-dazzling screen of plastic cement material in terms of stray light is absorbed advantageously.
Based on above structure, the embodiment of the present application also provides a kind of electronic equipment, which can include above-mentioned
The lens assembly that one embodiment is provided.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
