Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
The embodiment of the invention discloses a kind of terminal, which can be smart phone, tablet computer, laptop etc.
Terminal with the demand of taking pictures.The terminal has dual camera system.Specifically, as shown in figure 5, including in dual camera system
First camera 1 and second camera 2.Daylighting size needed for first camera 1 is less than the daylighting ruler of second camera 2
It is very little.According to design in the related technology, second camera 2 can possess biggish second light hole 200.
As shown in Figure 2, Figure 4 shows, the first camera 1 in the present embodiment includes shell 10, lens group 12, photosensitive element
(not going out in figure) and light shielding part 14.Shell 10 shields, and shell 10 surrounds assembly cavity 100, while on shell 10
It is provided with the first light hole 102 being connected to assembly cavity 100, lens group 12 and photosensitive element are arranged in assembly cavity 100.
In setting, in order to guarantee light by the way that optical element, lens group 12 can be exposed to after the first light hole 102 and lens group 12
It is required to photosensitive element opposite with the first light hole 102.
Lens group 12 includes at least the first lens 120, the first lens 120 protrude from the first light hole for focusing
102, at this point, from extraneous first camera 1 102 part of the first light hole, be merely able to see the side of the first light hole 102
Edge and the first lens 120 of centre, therefore the size of the two just constitutes the apparent size of the first camera 1.
Referring to Fig. 5, in dual camera system, the problem of in order to avoid " big ommatidium ", the first light hole 102 and second is logical
The aperture of unthreaded hole 200 needs to keep almost the same.And for the first camera 1, the normal daylighting demand of photosensitive element
So large-sized first light hole 102 is not needed to open up.Also, large-sized first light hole 102 can also make photosensitive member
Part receives excessive light, not only influences shooting effect, and damage photosensitive element is also possible to when serious.Therefore, increase merely
The scheme of one light hole, 102 size is infeasible.
In order to solve the problems, such as that photosensitive element can receive excessive light, the present embodiment is in the first lens 120 and photosensitive member
Light shielding part 14 is provided between part.There is transparent area 140 to penetrate for light at the middle part of light shielding part 14, and the area of transparent area 140 is wanted
Less than the cross-sectional area of the first light hole 102, meanwhile, projection of the transparent area 140 in the axis perpendicular with the first light hole 102
View field on face will also be located at the first light hole 102 in the view field on same perspective plane.In this way, light shielding part 14 is just
The peripheral region of the light entered by the first light hole 102 can be blocked, the light for only retaining intermediate region penetrates transparent area 140
It is irradiated on photosensitive element, photosensitive element is made to obtain suitable daylighting range.
The shape of light shielding part 14 and transparent area 140 can rounded, triangle, the various shapes such as rectangular, also, light transmission
The shape in portion 14 and the shape of transparent area 140 might not be also consistent, and be can according to need and carried out any selection.Due to mesh
Preceding first light hole 102 usually at circle, therefore in order to more match with the shape of the first light hole 102, recommend by transparent area 14
Using ring structure, i.e. the shape of the global shape Yu transparent area 140 of transmittance section 14 is circle, and the two is coaxial (referring to figure
3).At the same time, transmittance section 14 is also coaxial with the first light hole 102, and transparent area 140 is made to be located at the first light hole 102 just
Middle position.
Theoretically, appointing for the outflow of the light between the first lens 120 and photosensitive element channel can be set in light shielding part 14
Meaning position, however, light shielding part 14 is directly attached to first since light shielding part 14 needs to be fixed on a certain determining position
One side surface of lens 120 towards photosensitive element, which can save, is separately provided other fixed mechanisms for light shielding part 14, simplifies internal
Structure.
In most cases, will also include other than including the first lens 120 in lens group 12 at least one second
The quantity of lens 122, the second lens 122 can be configured according to performance requirements such as the focal lengths of camera.These second lens 122
It can be along the axial arranging of the first light hole 102 between the first lens 120 and photosensitive element.At this point, light shielding part 14 can be single
Solely setting, also can be set near these the second lens 122.For example, light shielding part 14, which can be set, is closing on the first lens
120 the second lens 122, that is, by the second lens 122 for closing on the first lens 120 along the first light hole 102
Between axial first the second lens 122 and the first lens 122 (referring to fig. 2 and Fig. 4).Light shielding part 14, which also can be set, to be faced
Second lens 122 of nearly photosensitive element, that is, by the second lens 122 for closing on the first lens 120 along the first light passing
Between axial the last one second lens 122 and photosensitive element in hole 102.Both the above set-up mode is in the second lens 122
Quantity be still applicable in when being only one.
When the quantity more than one of the second lens 122, light shielding part 14 also be can be set in two neighboring second lens 122
Between.It should be noted that the position of light shielding part 14 still can according to need and be adjusted at this time, such as light shielding part 14 can be with
Setting is between any two adjacent second lens 122.
Light shielding part 14 can use the layers structures such as coating, coating can since the thickness of these layer of structure is relatively thin
To be directly attached to the surface of lens group, without other fit structures.The material of layer structure can use ink, and ink both had
There is good shaded effect, while also there is good adhesive property, is capable of forming smooth, uniform layer structure.
In addition, light shielding part 14 can also use independent shading piece form, such as shading chip architecture annular in shape (referring to
Fig. 2 and Fig. 3), independent shading piece is convenient for being arranged between two adjacent lens, such as saturating in the first lens 120 and second
Between mirror 122, or between two adjacent the second lens 122.Light shielding parts 14 are clamped using two lens, make it can not be into
Row movement, realizes the fixation to light shielding part 14.
Also, when light shielding part 14 is fixedly clamped by two lens, light shielding part 14 can using with the surface of lens group with
The cyclic structure (such as anti-dazzling screen) of shape.For example, when light shielding part 14 is between the first lens 120 and the second lens 122, shading
The side surface that portion 14 is contacted with the first lens 120 and the first lens 120 are profile-followed, the side that light shielding part 14 is contacted with the second lens
Surface and the second lens 122 profile-followed (referring to fig. 4).Better cooperation can be obtained between light shielding part 14 and two lens in this way,
Reduce extrusion stress, to effectively prevent light shielding part 14 that radial deformation occurs because squeezing, influences shaded effect.
It is fixedly clamped for the ease of lens, the material of light shielding part 14 can use foam, and foam has good light-proofness
Can, while the surface roughness that also there is elasticity and increase, it can be kept by self-deformation and biggish stiction
It is relatively fixed with lens.
