Abstract
The utility model relates to a lens module with stray light reducing function, which is arranged inside the mobile phone and other electronic devices, comprising a lens barrel, a lens array, an image sensor, a coping and an interconnecting piece. A circular via hole is arranged inside the lens barrel, the lens array and the image sensor are both arranged inside the circular via hole of the lens barrel, a conic via hole is arranged inside the coping, the lens barrel is connected with the coping by the interconnecting piece, and the coping rotates around the interconnecting piece corresponding to the lens barrel, wherein, the lens barrel is fixedly installed inside the electronic device, and by the corresponding rotation to the lens barrel, the coping can be converted between the first position and the second position. When being at the first position, the coping lies side by side with the lens barrel inside the electronic device; but when being at the second position, the coping is overlapped with the lens barrel outside the electronic device. The lens module with stray light reducing function is used for decreasing the entering stray light of the camera to gain the light and small lens module.
Description
[technical field]
The utility model is the camera lens module that reduces the parasitic light function that has that is used for digital camera about a kind of, especially about a kind of less camera lens module of volume that reduces the parasitic light function that has that is adapted to mobile phone capable of taking pictures.
[background technology]
Along with Development of Multimedia Technology, digitized video such as digital camera, digital code camera product is by people's widespread use, has the large market demand, in addition, mobile phone is also developing to high-performance, multifunction direction fast in recent years, the key that is combined into development mobile multimedia technology of portable electronic equipments such as digital camera and mobile phone, PDA.In the saturating module of optical frames, parasitic light causes dazzles light and ghost can influence image quality, causes the fraction defective of product to rise.Usually, dazzle light and ghost for what reduce that parasitic light causes, increase by a lid before camera lens, please join Fig. 1, it covers 100 less parasitic lights for utilizing, wherein,
A is an incident angle of light
T is the thickness of this lid 100
B camera lens half angle of view
D aperture opening diameter size
Therefore, A=a*tan[(D+T*tanB)/T], get D=1.5mm, B=30 °, then obtain curve as shown in Figure 2.
As shown in Figure 2, when T=5mm, the incident light that surpasses more than 40 ° all can stop by tegmentum 100, thereby reaches the purpose of effective elimination parasitic light; In addition, T is bigger, then covers 100 and stops that the ability of parasitic light is stronger.Yet T thickness is excessive, will make camera lens module volume excessive, is unfavorable for that electronic installations such as mobile phone develop towards light littleization direction.
In view of this, provide a kind of volume less, and it is real in necessary effectively to reduce the camera lens module of parasitic light.
[utility model content]
The purpose of this utility model is to provide a kind of volume less, and can effectively reduce the camera lens module of parasitic light.
The utlity model has the camera lens module that reduces the parasitic light function, it is used to be installed in the electronic installations such as mobile phone, it comprises a lens barrel, a lens combination, an image sensor, a top cover and a junction, one circular port is set in this lens barrel, its connect this lens barrel two relatively the surface, this lens combination and this image sensor all place in the circular port of lens barrel, one bellmouth is set in this top cover, this bellmouth connect this top cover two relatively the surface, this connecting portion can make top cover rotate with respect to lens barrel around this connecting portion.Wherein, this lens barrel is fixedly installed in the above-mentioned electronic installation, this top cover, can be changed between a primary importance and a second place, when top cover is in its primary importance relative to the rotating of lens barrel by it, top cover is positioned at this electronic installation, and itself and lens barrel are side by side, and when the second place, top cover is positioned at outside this electronic installation, and it is folded mutually with lens barrel, and the axis of this circular port and this bellmouth is located along the same line.
Compare prior art, the camera lens module volume that the utlity model has reduction parasitic light function is less, can make electronic device miniaturization such as mobile phone by this throw-over gear, and can effectively reduce parasitic light.
[description of drawings]
Fig. 1 is the existing structure principle chart that reduces the parasitic light function;
Fig. 2 is to use the existing effect structure curve map that reduces the parasitic light function;
Fig. 3 is the idle state structural representation that the utlity model has the camera lens module that reduces the parasitic light function;
Fig. 4 is the working state structure synoptic diagram that the utlity model has the camera lens module that reduces the parasitic light function.
[embodiment]
Seeing also Fig. 3 and Fig. 4, to the utlity model has the camera lens module that reduces the parasitic light function be to be used for mobile phone capable of taking pictures, and it is loaded on the mobile phone body 9.
This has the camera lens module that reduces the parasitic light function and comprises a lens barrel 1, lens combination 2, an image sensor 3, a top cover 4 and a junction 6.
This lens barrel 1 is a rectangular parallelepiped, and a circular port 13 is set in it, and this hole 13 connects two facing surfaces 11 and the surface 15 of lens barrel 1.
This lens combination 2 comprises a plurality of lens, and this lens combination 2 and image sensor 3 all place in the circular port 13 of lens barrel 1, and lens combination 2 is positioned at the end near surface 11 of lens barrel 1, and image sensor 3 is positioned at the end near surface 15 of lens barrel.
This top cover 4 is cuboids, is provided with a bellmouth 41 in it, and this bellmouth 41 is a truncated cone-shaped along the cross section of axis, its run through top cover 4 two relatively the surface.
This shaft 6 is Hinge connecting structures, the part of Hinge connecting structure is installed on the surface 17 vertical with surperficial 11 of lens barrel 1, and near surface 11 1 ends, another part is installed on the surface 43 of top cover 4, and near surface 45, be used to connect this lens barrel 1 and this top cover 4, this lens barrel 1 and this top cover 4 can relatively rotate around this shaft 6, and its rotational angle is 180 °.This Hinge connecting structure can be positioned two positions respectively, and top cover 4 can be individually fixed in two positions thus, makes its not voltuntary movement under action of gravity.This mobile phone body 9 is provided with a containing cavity (figure is mark not), is used for ccontaining this and has the camera lens module that reduces the parasitic light function.
