Referring to fig. 1 and fig. 2, fig. 1 shows a method 10 for manufacturing a housing according to an embodiment of the present invention, where the method 10 is used for manufacturing a housing. Referring to fig. 2, the housing 100 is formed by machining a metal plate. The housing 100 is applied to a mobile terminal, which may be a mobile phone, a tablet computer, a notebook computer, or the like. The housing manufacturing method 10 includes the following steps.
In one embodiment, referring to fig. 3, the housing 100 is a rear battery cover of a mobile phone. The housing base 110 has a top wall 111, and the top wall 111 may be a large-area cover surface of the housing base 110, and the top wall 111 faces outwards when the housing base is applied to a mobile terminal. The portion to be processed 120 is a micro-slit hollow groove, is located on the top wall 111, and penetrates through the housing base 110. The portion to be protected 130 is protruded from the top wall 111 and is adjacent to the portion to be processed 120. An included angle a is formed between the portion to be protected 130 and the top wall 111. The part to be protected 130 has a peripheral wall 131, and the peripheral wall 131 includes a protection zone 132 adjacent to the part to be processed 120.
Further, referring to fig. 3, the portion to be protected 130 is a camera mounting boss, the portion to be protected 130 has a through hole 133, and the through hole 133 is used for matching with a camera to mount the camera.
Specifically, the housing 100 is made of metal, the housing 100 is a rear battery cover of the mobile terminal, and the housing 100 has a shielding effect on electromagnetic waves, so that an internal antenna of the mobile terminal cannot receive and transmit electric signals. By forming the micro-slit groove 120 (i.e., the portion to be processed 120) in the metal case 100 and filling the micro-slit groove 120 with the adhesive 150, the internal antenna of the mobile terminal can radiate a signal through the micro-slit groove 120. During the process of filling the rubber 150 into the micro-seam empty groove 120, the rubber 150 is likely to overflow and flow to the camera mounting boss 130 (i.e. the portion to be protected 130), so that the camera mounting boss 130 is affected by the rubber 150. An included angle a is formed between the camera mounting boss 130 and the top wall 111, when the rubber material 150 flows to the included angle a, the rubber material 150 on the camera mounting boss 130 is removed by adopting a polishing mode, the included angle a between the camera mounting boss 130 and the top wall 111 is difficult to polish, if the included angle a is polished forcibly, the camera mounting boss 130 is possibly over-polished, the structure of the camera mounting boss 130 is deformed, and the integral appearance and the forming precision of the shell are influenced.
In another embodiment, referring to fig. 4 and 5, the housing 100 is a rear battery cover of a mobile phone. The housing base 110 has a top wall 111, the top wall 111 may be a cover surface with a large area of the housing base 110, and when the housing base is applied to a mobile terminal, the top wall 111 is an appearance surface. The portion to be processed 120 is a colored region of the top wall 111, which requires a process such as anodic oxidation to dye the housing. The portion to be protected 130 is an identification area of the top wall 111, and the identification area is an area on the housing where characters are engraved, logo is printed, trademarks are printed, and the like. The identification region need not be dyed. When the portion to be protected 130 is only several or several tens of micrometers away from the portion to be processed 120, it is difficult for the portion to be protected 130 to avoid the influence of the processing process of the portion to be processed 120.
In one embodiment, the housing 100 is a rear cover of a battery, and the step 101 of providing the housing base 110 includes the following steps.
Step 1, cutting a shell raw material, and performing multiple times of die stamping to form a shell plate material with uniform thickness, wherein the shell raw material is made of a metal material.

Referring to fig. 11, fig. 11 is a housing 100 according to an embodiment of the disclosure. The housing 100 is manufactured by the housing manufacturing method 10 according to any of the above embodiments.
The housing 100 includes a housing base 110. The housing base 110 has a top wall 111. The portion to be processed 120 is a micro-slit hollow groove and is located on the top wall 111. Treat that protection portion 130 is protruding to be located roof 111, treat that protection portion 130 has periphery wall 131, periphery wall 131 is the cambered surface.
Optionally, the portion to be protected 130 is a boss structure, and has a through hole 133, and the through hole 133 is used for positioning an electronic component. The electronic element can be a camera assembly, a flash lamp, a fingerprint identification assembly, a key and the like.
Optionally, the portion to be protected 130 has a protection zone 132. The guard region 132 is connected to the top wall 111 and is adjacent to the part to be processed 120. The guard 132 is a curved surface. A chamfer 113 is formed between the guard 132 and the top wall 111.
In one embodiment, the housing 100 is a metal housing, and the portion to be processed 120 may be an antenna micro-slit cavity for radiating a signal. The portion 130 to be protected is a crater-shaped camera mounting boss for positioning the camera. A chamfer 113 is formed between the peripheral wall 131 of the portion to be protected 130 and the top wall 111. In the manufacturing method of the housing 100, the micro-slit groove 120 and the camera mounting boss 130 are formed, and the distance between the micro-slit groove 120 and the camera mounting boss 130 is 100 um-2 mm. In order to seal the micro-seam groove 120, glue is filled into the micro-seam groove 120, and during the glue filling process, the glue is likely to overflow the micro-seam groove 120, and the micro-seam groove 120 is closely spaced to the camera mounting boss 130, so that the glue is likely to flow into the chamfer 113 between the camera mounting boss 130 and the top wall 111. Once the glue flows into the chamfer 113, the glue needs to be ground away by sanding, but the sanding process may damage the top wall 111 and the camera mounting boss 130, resulting in a reduction in the texture and accuracy of the housing 100, as well as reducing the efficiency of the processing of the housing 100.
