A method of manufacturing the housing 100 and the housing 100 of the terminal 500 according to an embodiment of the present application will be described below with reference to FIGS. As used herein, "terminal" includes, but is not limited to, a satellite or cellular telephone (such as a cell phone); a personal communication system (PCS) terminal that can combine cellular radiotelephone with data processing, fax, and data communication capabilities; can include a radiotelephone, Paging, Internet/Intranet access, Web browser, Notepad, calendar, and/or PDA for Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or including radiotelephone transceivers Other electronic devices.

As shown in FIG. 1 to FIG. 13 , according to the housing 100 of the terminal 500 according to the embodiment of the present application, the housing 100 includes a first metal layer 10 and a second metal layer 20 .

Specifically, the materials of the first metal layer 10 and the second metal layer 20 are different, and the first metal layer 10 and the second metal layer 20 are stacked. For example, as shown in the example of FIG. 3, the first metal layer 10 may be a stainless steel layer, and the second metal layer 20 may be an aluminum alloy layer.

It should be noted that the first metal layer 10 and the second metal layer 20 are made of different metal materials, and the overall performance of the housing 100 of the terminal 500 can be enhanced by using different metal material characteristics. For example, the first metal layer 10 may be a stainless steel layer and the second metal layer 20 may be an aluminum alloy layer. It can be understood that the stainless steel has high structural strength, but has a large density and a large weight. The structural strength of the aluminum alloy is relatively low, which facilitates the processing of the structure of the casing 100, and the aluminum alloy is light in weight. The housing 100 configured as the terminal 500 is stacked by metal layers of different materials, so that the housing 100 can have sufficient structural strength and aesthetic appearance, and the weight of the housing 100 can be reduced, thereby facilitating the thinning of the terminal 500. design.

According to the housing 100 of the terminal 500 of the embodiment of the present application, by using the first metal layer 10 and the second metal layer 20 of different materials to form the housing 100 configured as the terminal 500, the terminal 500 can be improved by utilizing characteristics of different metal materials. The overall performance of the housing 100 provides the housing 100 with high structural strength and aesthetic appearance, and can effectively reduce the weight of the housing 100, thereby facilitating the slim and light design of the terminal 500. Moreover, the housing 100 of the terminal 500 has a simple structure, convenient processing, low production cost, and improves the market competitiveness of the terminal 500 product.

According to some embodiments of the present application, for example, as shown in the examples in FIGS. 3 and 4, the surface of the first metal layer 10 remote from the second metal layer 20 is configured as the outer surface 110 of the housing 100, the second metal layer The surface of the 20 away from the first metal layer 10 is configured as the inner surface 210 of the housing 100, and the hardness of the first metal layer 10 is greater than the hardness of the second metal layer 20. It is to be understood that the housing 100 of the terminal 500 forms the chamber 70 of the terminal 500, and the main components of the terminal 500 (such as a pcb motherboard, battery, etc.) may be disposed within the chamber 70. The outer surface 110 of the housing 100 and the inner surface 210 of the housing 100 described herein are relative to the chamber 70 of the terminal 500. For example, the side of the housing 100 facing the interior of the chamber 70 (the inner side as shown in FIGS. 3 and 4) is the inner surface 210 of the housing 100, and the housing 100 faces the side outside the chamber 70 (see FIG. 3). The outer side shown in FIG. 4 is the outer surface 110 of the housing 100. By setting the hardness of the first metal layer 10 to be greater than the hardness of the second metal layer 20, and making the surface of the first metal layer 10 remote from the second metal layer 20 be configured as the outer surface 110 of the casing 100, thereby, The outer surface 110 of the housing 100 has a high structural strength, so that the deformation of the terminal 500 due to the extrusion can be effectively prevented, affecting the appearance of the terminal 500 and even causing damage to the terminal 500.

According to an embodiment of the present application, the thickness of the first metal layer 10 is smaller than the thickness of the second metal layer 20. It should be noted that the first metal layer 10 may be disposed on the outer side of the second metal layer 20 (in the inner and outer directions as shown in FIGS. 3 and 4 ), and the surface of the first metal layer 10 away from the second metal layer 20 may be It is configured as an outer surface 110 of the housing 100. Accordingly, the surface of the second metal layer 20 away from the first metal layer 10 may be configured as the inner surface 210 of the housing 100. Since the housing 100 of the terminal 500 is required to have high aesthetics and structural strength, the first metal layer 10 can select a stainless steel layer having a higher brightness and hardness, and the second metal layer 20 can select an aluminum alloy layer. It can be understood that the stainless steel layer has a relatively high density and a large weight; the aluminum alloy has a small density and a light weight. Setting the thickness of the first metal layer 10 to be smaller than the thickness of the second metal layer 20 can reduce the overall weight of the housing 100, and is advantageous for achieving a slim design of the terminal 500. In other embodiments of the present application, the thickness of the first metal layer 10 may also be equal to or greater than the thickness of the second metal layer 20.

Further, the first metal layer 10 has a thickness of 0.2 to 0.4 mm, and the second metal layer 20 has a thickness of 0.6 to 0.8 mm. After experimental testing, the thickness of the first metal layer 10 was set to 0.2 mm to 0.4 mm. When the thickness of the second metal layer 20 is 0.6-0.8 mm, the housing 100 can have a high structural strength and can reduce the overall thickness and overall weight of the housing 100. For example, in one embodiment of the present application, the first metal layer 10 may have a thickness of 0.3 mm, and the second metal layer 20 may have a thickness of 0.7 mm.

According to an embodiment of the present application, the first metal layer 10 may be a stainless steel member and the second metal layer 20 may be an aluminum alloy member. For example, as shown in the examples in FIGS. 3 and 4, the first metal layer 10 may be disposed outside the second metal layer 20 (in the inner and outer directions as shown in FIGS. 3 and 4), and the first metal layer 10 is far away. The surface of the second metal layer 20 may be configured as the outer surface 110 of the housing 100. The first metal layer 10 can be selected to use a stainless steel member having a high structural strength, which can prevent the deformation of the terminal 500 from affecting the appearance of the product when the terminal 500 is squeezed, and even cause damage to the terminal 500, and effective protection. The terminal 500 product. Moreover, the stainless steel member has a high brightness and metallic texture, and the first metal layer 10 can enhance the aesthetic appearance of the terminal 500 by using a stainless steel member. The second metal layer 20 may be an aluminum alloy member. Compared with the stainless steel member, the aluminum alloy member has a lower density and a lighter weight, and the second metal layer 20 is made of an aluminum alloy member, which can effectively reduce the overall weight of the housing 100, and The two metal layers 20 may be disposed inside the first metal layer 10, and the second metal layer 20 does not affect the overall aesthetics of the housing 100. In addition, the structural strength of the aluminum alloy member is relatively low, facilitating the processing and manufacturing of the internal structure of the casing 100.

As shown in the example of FIG. 2, the surface of the first metal layer 10 that faces the outside of the chamber 70 (in the inner and outer directions as shown in FIG. 2) is configured as the outer surface 110 of the housing 100. An antenna slot 60 may be disposed on the first metal layer 10, thereby reducing signal interference of the metal casing to the terminal 500 and improving communication transmission performance of the terminal 500.

According to the manufacturing method of the housing 100 of the terminal 500 according to the embodiment of the present application, the housing 100 is the housing 100 of the terminal 500 according to the above, and the manufacturing method includes: housing the laminated body of the first metal material and the second metal material The blank is machined to form the housing 100. For example, the first metal material can select a metal material having a good hardness and appearance, and the second metal material can select a metal material having a relatively small density and a relatively small hardness. Thereby, the housing 100 can be made to have a higher structural strength while helping to reduce the weight of the housing 100.

According to the manufacturing method of the housing 100 of the terminal 500 according to the embodiment of the present application, different materials can be utilized by laminating the first metal material and the second metal material of two different materials into a housing blank and processing to form the housing 100.

S20: The housing blank is machined to form the housing 100.

For example, the first blank and the second blank can be selected from different metals or alloys. For example, the first blank may be selected from stainless steel, and the second blank may be selected from aluminum alloy. First, the stainless steel and the aluminum alloy blank can be processed into a plate, the first blank plate and the second blank plate are surface-treated, rolled and composited into a composite metal layer, and the composite metal layer is appropriately sized to be cut into a shell. Body blanks. Subsequently, the casing blank is subjected to a rough milling, CNC (Computer Numerical Control Machine Tools) process or the like to form the casing 100.

Thus, the first metal layer 10 and the second metal layer 20 of different materials are selected to be rolled into a casing blank, and the casing blank is further processed to form the casing 100. The processing method is simple in operation, convenient in processing, and high in processing precision, and effectively improves the processing efficiency of the housing 100 of the terminal 500, thereby reducing the production cost. Moreover, the housing 100 of the terminal 500 manufactured by the manufacturing method includes two layers of metal of different materials, which can ensure the structural strength and the appearance of the housing 100, and can reduce the overall weight of the housing 100.

According to an embodiment of the present application, as shown in FIG. 8, after step S20, the following steps may be performed:

S30: The casing 100 is subjected to anti-corrosion treatment. It should be noted that the first metal layer 10 and the second metal layer 20 of the housing 100 adopt two different metal layers, and the junction of the first metal layer 10 and the second metal layer 20 is exposed to the air in the air. The moisture and gas components form a galvanic cell with two different metals, causing electrochemical corrosion of the casing 100. The metal active layer in the first metal layer 10 and the second metal layer 20 easily loses electrochemical corrosion of the electrons, thereby causing corrosion damage of the casing 100 and affecting the service life of the casing 100. By performing the anti-corrosion treatment on the casing 100, the corrosion resistance of the casing 100 can be effectively improved, and the service life of the casing 100 can be prolonged.

In other words, the casing 100 may be immersed in the anticorrosive syrup for anti-corrosion treatment, or the surface of the casing 100 may be subjected to PVD (Physical Vapor Deposition) plating or an AF layer. Thereby, the anti-corrosion performance of the casing 100 can be improved after the anti-corrosion treatment, thereby prolonging the service life of the casing 100.

According to an embodiment of the present application, as shown in FIG. 9, in step S20, the housing blank is stamped to form the housing 100. In other words, the housing blank can be machined using a stamping process to stamp the housing blank into the housing 100. Thereby, the operation is convenient, and the manufacturing efficiency of the casing 100 can be improved. In other embodiments of the present application, the housing blank may also be milled into the housing 100. For example, the housing blank may be first rough-milled to form a chamber 70 of the housing 100, and then the housing 100 may be finished by CNC, and the inner cavity, outer structure, outer surface 110 of the housing 100 may be finished.

It is to be understood that in order to prevent signal interference of the metal housing 100 to the terminal 500, the antenna slot 60 needs to be processed on the housing 100. The antenna slot 60 facilitates signal transmission, thereby improving the signal transmission capability of the terminal 500. Filling the layer 610 with the processed antenna slot 60 can flatten the outer surface 110 of the housing 100 to improve the aesthetics of the terminal 500.

Further, the filling layer 610 may be an ink layer or a paint layer. That is, the ink layer may be filled in the antenna groove 60, or the paint layer may be filled in the antenna groove 60. The ink layer and the paint layer have a good insulating effect, and can effectively prevent an interference signal from being formed on the housing 100 of the terminal 500, thereby improving the signal transmission capability of the terminal 500. Moreover, by using an ink layer and a paint layer, the material is inexpensive and easily available, and the production cost can be reduced.

S11: The functional hole 40 is machined on the housing blank. For example, the function hole 40 can be finished milling on the housing 100 using CNC technology, and the function hole 40 can be a through hole or a blind hole. For example, the function hole 40 may be a headphone jack, a USB port, a microphone hole, a side key mounting hole, or the like. Of course, the function holes 40 may also be blind holes that are milled on the housing 100 to prevent mutual interference between the internal structures of the terminal 500.

Further, in step S11, the shell blank is processed by a laser engraving, CNC, or etching process to form the functional holes 40. In other words, the processing of the functional holes 40 in the housing blank may be performed by a laser engraving process or a CNC process, and of course etching or other processing may be employed. In the actual processing process, the corresponding processing technology can be selected according to the precision size requirement and the processing cost.

Further, in step S12, injection molding is performed at the joint 30 to form the wrap layer 50. For example, as shown in the example of FIG. 5, a polybutylene terephthalate (polybutylene terephthalate) may be formed at the joint 30 to form a wrap layer 50, and the wrap layer 50 covers the joint 30. . Thereby, the corrosion resistance of the casing 100 can be improved, and the service life of the casing 100 can be extended.

In still other embodiments of the present application, in step S12, the recess may be machined at the joint 30 and then the wrap layer 50 may be provided at the joint 30. For example, as shown in the example in FIG. 3, a portion of the second metal layer 20 may be removed to form a depressed portion at the junction of the first metal layer 10 and the second metal layer 20. Alternatively, as shown in the example in FIG. 6, at the junction of the first metal layer 10 and the second metal layer 20, a portion of the first metal layer 10 and a portion of the second metal layer 20 are simultaneously removed to form a depressed portion, the first metal layer.

Further, in step S12, a plurality of spaced apart grooves may be provided on the surface of the casing blank that is in contact with the wrapping layer 50 before the wrapping layer 50 is disposed. For example, nanopore processing can be performed on the inner surface 210 of the second metal layer 20 using nanotechnology. Thereby, the connection between the wrapping layer 50 and the casing 100 is facilitated, and the strength of the connection between the wrapping layer 50 and the casing 100 can be enhanced.
