Technical field
The present invention relates to bonnet processing technique field, more particularly to a kind of processing method of bonnet, bonnet and mobile terminal.
Background technology
With continuing to develop for electronic communication technology, mobile terminal develops to frivolous direction, to pursue more preferably feel；Together
When to pursue the high pixel and definition of camera, camera module size can not compress again, cause mobile phone thickness direction space
It is nervous.As shown in figure 1, the position that the bonnet 101 of most of product installs rear camera has raised camera case ring
102.Current aluminium alloy bonnet, the implementation of the bulge-structure of camera case ring has following two：(1) camera case ring
It is the two-part structure (split type) separated with bonnet, such as Fig. 2 and Fig. 3.Camera module is arranged on bonnet 205.The shooting
Head mould group includes：Camera eyeglass 201, the first layers of two-sided 202, camera case ring 203, the second layers of two-sided 204 and take the photograph
As first 206.The camera case ring 203 and bonnet 205 are separated two-part structures.This two-part structure need to be separated and used
Computer digital control machine tool technique (CNC, Computer numerical control)) processing.(2) bonnet is with camera
Overall structure (integral type), such as Fig. 4 and Fig. 5.The camera module is arranged on bonnet 405.The camera module includes：Shooting
Head mirror 401, layers of two-sided 402 and camera 404.The camera case ring 403 is integral structure with bonnet 405, it is necessary to lead to
Cross the overall machining of computer digital control machine tool technique.
The computer digital control machine tool technique processing capacity that above-mentioned (1) plants mode is small, and cost is relatively low；But, assembling
Part is more, camera position thickness of thin (A, B size in such as Fig. 3), and intensity is weak, camera poor reliability, by falling, roller
Experiment discovery is easily damaged camera.(2) plant the structure design of mode, it is to avoid camera position structural weak problem (such as Fig. 5
Middle C sizes), intensity is high, can hoisting drum, fall-down test camera reliability, outward appearance is without fit-up gap；But, processing shooting
Head decoration coil structures need large area to use computer digital control machine tool technique, and cost is high.
The content of the invention
The embodiment of the present invention provides a kind of processing method of bonnet, to solve the shooting that there is protrusion to set of prior art
The processing capacity of the processing method of the bonnet of head case ring is big and camera position at low intensity the problem of.
The embodiment of the present invention also provides a kind of bonnet, to solve the camera case ring that there is protrusion to set of prior art
Bonnet processing capacity is big and camera position at low intensity the problem of.
The embodiment of the present invention provides a kind of mobile terminal again, is filled with the camera that there is protrusion to set for solving prior art
The processing capacity of the mobile terminal of the bonnet of decorative circle is big and camera position at low intensity the problem of.
First aspect there is provided a kind of processing method of bonnet, including：Stamping process is carried out to metal crude green body, imaged
The profile of head case ring protrudes from the bonnet crude green body of rear exterior surface；Using computer digital control machine tool technique to the bonnet
The profile of the outer surface of crude green body and the camera case ring carries out finishing processing.
Second aspect is obtained there is provided a kind of bonnet, the bonnet by the processing method processing of above-mentioned bonnet.
There is provided a kind of mobile terminal, including above-mentioned bonnet for the third aspect.
So, in the embodiment of the present invention, by punching press and computer digital control machine tool technique connected applications, first with punching
The mode of pressure, the camera for stamping out projection in the thick embryo surface of metal decorates coil structures, then passes through computer numerical control (CNC) machine
Bed process finishes the outer surface of camera case ring profile and bonnet, realizes that camera case ring is integrally formed formula with bonnet
Structure；In addition, it is thus also avoided that processing the camera decoration coil structures of projection in the prior art needs computer digital control machine tool
Computer digital control machine tool technique processing capacity in the large area processing of technique, the bonnet processing method of the present embodiment is small, section
Cost-saving, while to be integrally formed the structure that the structure of formula improved at camera case ring position strong for camera case ring and bonnet
Degree, is conducive to protecting camera.
