Description
Technical field
Of the invention and a kind of zirconia ceramics mobile phone backboard, belongs to Cellphone Accessories technical field.
Background technology
The material of phone housing selects, no matter appearance, the feel to mobile phone itself, still technique in the fabrication process,
Suffer from prodigious influence.The shell of mobile phone nearly all uses plastic material at present.This plastic handset shell is although at low cost,
It is easy molding making, but texture is bad, it is more dull, even if the different designs element such as decorative pattern or simulated leather is added, but with regard to feel
For it is still more inferior；In addition the heat dissipation effect of plastic handset shell is general, especially with the plastic material of makrolon, it
Comparatively it is the non-conductor of heat, it means that heat possibly can not disperse in time, it is possible to can influence the operation of mobile phone
Effect；Plastic handset shell is easily deformed etc. there is also difference of hardness.
In recent years, metal, glass even leather, sapphire etc. can use on mobile phone, it is made to become high-end, smart
U.S., meets the aesthetic requirement of different people, but the above material have the shortcomings that it is respective, such as metallic mobile phone shell, heat
Cause feel uncomfortable.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and it is simple to provide a kind of production method, makes effect
Rate is high, at low cost, and density is high, and intensity is good, and sense of touch exquisiteness and lustrous surface can have the color and luster and texture of jade by toning,
Color-variable, class is high, and electromagnetic interference is few, and electric signal loses small, the good zirconia ceramics mobile phone backboard of safety.
To achieve the above object, the present invention adopts the following technical scheme that：A kind of zirconia ceramics mobile phone backboard, including a length
It is rectangular, there is the mobile phone backboard body of arc transition, the mobile phone backboard body to use compound zirconia material four corners
Material injection forming forms, and the inner face of the mobile phone backboard body is provided with rectangular concave lacking groove, and at least forms four and be connected
Frame side；The outer face surface of the mobile phone backboard body has lappingout superficial layer and in four edge arc transition to inner face side
Edge；One upper end side of centre of the mobile phone backboard body is described at least provided with a camera preformed hole and flash lamp preformed hole
End edge is provided with the button key and UBS sockets preformed hole and speaker sound aperture of at least one strip in the side of concave lacking groove.
As preferred：Four frame sides of the inner face of the mobile phone backboard body are respectively arranged with locating notches make bar-shaped trough, and
Make two-by-two frame be connected while with respective arc transition corner frame, the depth of the locating notches make bar-shaped trough is notch groove depth
Half, the outside thickness of locating notches make bar-shaped trough are less than the one third of width；The thickness of the mobile phone backboard body is 5-
10mm, wherein notch groove depth is in 3-8mm；Uniformly be parallel in the groove bottom of the concave lacking groove long side or be in cross
, highly be not more than 0.1mm a plurality of shallow rib.
The invention belongs to improvements over the prior art, it has production method simple, and producing efficiency is high, at low cost, density
Height, intensity is good, and sense of touch exquisiteness and lustrous surface can have the color and luster and texture of jade by toning, and color-variable, class is high,
The features such as electromagnetic interference is few, and electric signal loss is small, and safety is good.
