Description

Burnt understructure after a kind of photographic head

Technical field

This utility model relates to photographic head technical field, burnt understructure after particularly relating to a kind of photographic head.

Background technology

Constantly developing along with society and constantly improve with science and technology, consumer is also more and more higher to the requirement of mobile phone, especially the frivolous degree of mobile phone, is an important references criterion of consumer's selection mobile phone. Photographic head is as the important spare part of mobile phone, the reasonability of its structural design is directly connected to the frivolous degree of whole mobile phone, and its base is the vitals being related to module height, therefore, shorter base also just can make more frivolous photographic head module, thus producing more frivolous mobile phone products.

Utility model content

The purpose of this utility model is to overcome weak point of the prior art, it is provided that a kind of reasonable in design, so that burnt understructure after the lightening photographic head of photographic head module.

The purpose of this utility model is achieved through the following technical solutions:

Burnt understructure after a kind of photographic head, including: plank, base and optical filter;

Described base is connected formation one hollow cavity with described plank, and described plank is positioned at described hollow cavity and has an installed surface, and described installed surface is provided with chip and gold thread;

Described base has an inner surface and outer surface, and described inner surface is positioned at described hollow cavity and relative with described installed surface, and described outer surface is positioned at outside described hollow cavity and away from described installed surface;

Described inner surface is provided with a projection, and described projection protrudes along near described installed surface side;

Offering a groove on described outer surface, described groove is along near described installed surface side depression;

Described optical filter is installed in described groove.

Wherein in an embodiment, described optical filter is infrared fileter.

After photographic head, burnt understructure mainly sets a projection on the inner surface of base, offers a groove, reasonable in design on the outer surface, thus it is lightening to realize photographic head module simultaneously.

Accompanying drawing explanation

Fig. 1 is the sectional view of burnt understructure after traditional photographic head;

Fig. 2 be this utility model one embodiment photographic head after the sectional view of burnt understructure;

Fig. 3 is the top view of burnt understructure after the photographic head shown in Fig. 2.

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.

As it is shown in figure 1, it is the sectional view of burnt understructure 10 after traditional photographic head. The thinnest back focal length that can assemble from for the spatial altitude that H1, A are chip, electric capacity is put, gold thread is avoided, B be injection mo(u)lding for supporting the minimum thickness of optical filter, C is filter thickness, therefore H1=A+B+C.

As in figure 2 it is shown, the sectional view of burnt understructure 20 after the photographic head that it is this utility model one embodiment. After photographic head, burnt understructure 20 includes: plank 100, base 200 and optical filter 300. In the present embodiment, optical filter 300 is infrared fileter. In other embodiments, optical filter 300 not just infrared fileter, it is also possible to be the optical filter of other light.

Base 200 is connected formation one hollow cavity 400 with plank 100, and plank 100 is positioned at hollow cavity 400 and has an installed surface 110, and installed surface 110 is provided with chip 112 and gold thread 114.

Base 200 has an inner surface 210 and outer surface 220, and inner surface 210 is positioned at hollow cavity 400 and relative with installed surface 110, and outer surface 220 is positioned at the outer and remotely mounted face 110 of hollow cavity 400.

Inner surface 210 is provided with a projection 212, and projection 212 protrudes along near installed surface 110 side. Offering a groove 222 on outer surface 220, groove 222 is along near installed surface 110 side depression. Optical filter 300 is installed in groove 222.

As it is shown on figure 3, this utility model base is to there is certain distance between utilizing outside the photosensitive region 115 of chip 112 outside the non-photo-sensing region 116 of chip 112, protruded by product between this segment distance and optical filter 300 and then under sink and design. Assume that the photosensitive region 115 of chip 112 is sized to Y*Y, and the non-photo-sensing region 116 of chip 112 be sized to X*X, by also having some regions between Y*Y position to X*X position, the region set up between W*W and Z*Z is protruded toward chip 112 direction, design the position of optical filter 300 laminating in this region, wherein W*W position is light hole 117 simultaneously.

Visible, the thinnest back focal length that can assemble of this utility model is from for H2, A are chip, electric capacity is put, gold thread is avoided spatial altitude, B is that injection mo(u)lding is for supporting the minimum thickness of optical filter, C is filter thickness, and D newly designs the thickness protruded, H2=A+B+C-D.

Please refer to Fig. 1 and Fig. 2, by comparison, after photographic head of the present utility model, the back focal length of burnt understructure 20 is from H2=A+B+C-D, after traditional photographic head, the back focal length of burnt understructure 10 is from H1=A+B+C, compare it can be seen that burnt understructure 20 decreases the thickness of D compared to Jiao's understructure 10 after traditional photographic head after photographic head of the present utility model.

After photographic head, burnt understructure 20 mainly sets a projection 212 on the inner surface 210 of base 200, offers a groove 222, reasonable in design, thus it is lightening to realize photographic head module on outer surface 220 simultaneously.

Above-described embodiment is this utility model preferably embodiment; but embodiment of the present utility model is also not restricted to the described embodiments; other any without departing from the change made under spirit of the present utility model and principle, modification, replacement, combination, simplification; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
