Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
Inventor has found that light-sensitive element is failed mainly under strong light due to the effective sensitization area of existing light-sensitive element
Greatly, end face and side are effective sensitization area, and when light-sensitive element is arranged near liquid crystal display, liquid crystal display is to light
The refraction and diffusing reflection of line can also influence the photosensitive of light-sensitive element.Between this, a kind of light-sensitive element installation knot is inventors herein proposed
Structure fails when solving the problems, such as strong light.
As shown in Figure 1, 2, the light-sensitive element mounting structure of the utility model include shell, liquid crystal display 2, light-sensitive element 3 with
And shading sleeve 4.
Liquid crystal display 2 is arranged in shell, and light-sensitive element 3 is arranged in the side of liquid crystal display 2, and shading sleeve 4 is around setting in light
The side of quick element 3, so that the effective sensitization area of light-sensitive element 3 is the upper surface of light-sensitive element 3.
Preferably, shell includes lower housing 11 and and the upper shell 12 that is removably mounted on lower housing 11.Upper casing
There is body 12 display area 121 and photosensitive region 122, liquid crystal display 2 to be arranged below display area 121, and light-sensitive element 3 is arranged
Below photosensitive region 122, display area 121 is transparent with photosensitive region 122, to can see by display area 121
The content of liquid crystal display 2, light can be incident on by photosensitive region 122 at light-sensitive element 3.
Further include circuit board 13 in shell 1, liquid crystal display 2 and light-sensitive element 3 are arranged on circuit board 13, and and circuit
13 signal of plate connects, and the brightness of liquid crystal display 2 is adjusted in the light intensity that circuit board 13 is detected according to light-sensitive element 3.
Preferably, the geomery of photosensitive region 122 is identical as the geomery of 3 upper surface of light-sensitive element, to ensure
External light is incident on by photosensitive region 122 on light-sensitive element 3.In order to avoid the region around photosensitive region 122 is to light
The reflection or diffusing reflection of line influence light-sensitive element 3, and light shield layer 123 is equipped with around photosensitive region 122.Light shield layer 123 can lead to
The spraying black-out paint on upper shell 12 is crossed to be formed in around photosensitive region 122.It is noted that light shield layer 123 is avoided showing
Show that region 121 is arranged.
By the way that light shield layer 123 is arranged, the intensity of illumination that photosensitive region 122 receives can be effectively reduced, while can keep away
Exempt from the refracted light near light-sensitive element 3 and influence of the diffusing reflection light to light-sensitive element 3.
Preferably, upper shell 12 has a downwardly open installation room 124, and the upper surface of installation room 124 is photosensitive region
122, the upper end of light-sensitive element 3 and shading sleeve 4 is inserted into installation room 124, by installing room 124 by light-sensitive element 3 and shading
Set 4 is maintained at fixed position.
Preferably, the upper surface of shading sleeve 4 is butted on the top surface of installation room 124, to reduce the unrestrained anti-of installation 124 top surface of room
It penetrates.
