[0078] Reference below Figure 1-Figure 13 The housing 100 of the terminal 500 and the manufacturing method of the housing 100 according to the embodiment of the present invention are described. "Terminals" used here include, but are not limited to satellites or cellular phones (such as mobile phones); personal communication system (PCS) terminals that can combine cellular radio phones with data processing, fax, and data communication capabilities; can include radio phones, Pager, Internet/Intranet access, Web browser, note book, calendar, and/or PDA with global positioning system (GPS) receiver; and conventional laptop and/or palmtop receiver or including radio telephone transceiver Other electronic devices.

[0079] Such as Figure 1-Figure 13 As shown, according to the housing 100 of the terminal 500 according to the embodiment of the present invention, the housing 100 includes: a first metal layer 10 and a second metal layer 20.

[0080] 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. E.g, image 3 As shown in the example, the first metal layer 10 may be a stainless steel layer, and the second metal layer 20 may be an aluminum alloy layer.

[0081] It should be noted that the first metal layer 10 and the second metal layer 20 are made of different metal materials, and the characteristics of different metal materials can be used to enhance the overall performance of the housing 100 of the terminal 500. 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 is understandable that stainless steel has a higher structural strength, but a higher density and a higher weight. The structural strength of the aluminum alloy is relatively low, which facilitates the processing of the structure of the housing 100, and the aluminum alloy is light in weight. The housing 100 of the terminal 500 is constructed by stacking metal layers of different materials, which not only enables the housing 100 to have sufficient structural strength and aesthetic appearance, but also reduces the weight of the housing 100, which is conducive to achieving a lighter and thinner terminal 500 design.

[0082] According to the case 100 of the terminal 500 according to the embodiment of the present invention, the first metal layer 10 and the second metal layer 20 of different materials are stacked to form the case 100 of the terminal 500, so that the characteristics of different metal materials can be used to improve the terminal 500. The overall performance of the housing 100 enables the housing 100 to have high structural strength and aesthetic appearance, and can effectively reduce the weight of the housing 100, which facilitates the realization of the thin and light design of the terminal 500. In addition, the housing 100 of the terminal 500 has a simple structure, convenient processing, and low production cost, which improves the market competitiveness of the terminal 500 product.

[0083] According to some embodiments of the present invention, for example, image 3 with Figure 4 As shown in the example, the surface of the first metal layer 10 away from the second metal layer 20 is configured as the outer surface 110 of the housing 100, and the surface of the second metal layer 20 away from the first metal layer 10 is configured as the housing On the inner surface 210 of 100, the hardness of the first metal layer 10 is greater than the hardness of the second metal layer 20. It should be understood that the housing 100 of the terminal 500 forms a cavity 70 of the terminal 500, and the main components of the terminal 500 (such as a PCB motherboard, a battery, etc.) may be disposed in the cavity 70. The outer surface 110 of the housing 100 and the inner surface 210 of the housing 100 described here are relative to the cavity 70 of the terminal 500. For example, the housing 100 faces one side of the chamber 70 (such as image 3 with Figure 4 The inner side shown in) is the inner surface 210 of the housing 100, and the side of the housing 100 facing the outside of the chamber 70 (such as image 3 with Figure 4 The outside shown in) is the outer surface 110 of the housing 100. By setting the hardness of the first metal layer 10 to be greater than that of the second metal layer 20, and the surface of the first metal layer 10 away from the second metal layer 20 is configured as the outer surface 110 of the housing 100, it is possible to make The outer surface 110 of the housing 100 has a relatively high structural strength, which can effectively prevent the terminal 500 from being deformed due to extrusion, affecting the appearance of the terminal 500 and even causing damage to the terminal 500.

[0084] According to an embodiment of the present invention, 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 outside the second metal layer 20 (such as image 3 with Figure 4 The inner and outer directions shown in ), the surface of the first metal layer 10 away from the second metal layer 20 may be configured as the outer surface 110 of the housing 100. Correspondingly, 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 higher aesthetics and structural strength, the first metal layer 10 can be a stainless steel layer with higher brightness and hardness, and the second metal layer 20 can be an aluminum alloy layer. It is understandable that the density of the stainless steel layer is higher and the weight is higher; the density of the aluminum alloy is lower and the weight is lighter. 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 facilitate the realization of a thin and light design of the terminal 500. In other embodiments of the present invention, the thickness of the first metal layer 10 may also be equal to or greater than the thickness of the second metal layer 20.

[0085] Further, the thickness of the first metal layer 10 is 0.2-0.4 mm, and the thickness of the second metal layer 20 is 0.6-0.8 mm. After experimental testing, when the thickness of the first metal layer 10 is set to 0.2 mm-0.4 mm. When the thickness of the second metal layer 20 is 0.6-0.8 mm, the housing 100 can have a higher structural strength and the overall thickness and weight of the housing 100 can be reduced. For example, in an embodiment of the present invention, the thickness of the first metal layer 10 may be 0.3 mm, and the thickness of the second metal layer 20 may be 0.7 mm.

[0086] According to an embodiment of the present invention, the first metal layer 10 may be a stainless steel piece, and the second metal layer 20 may be an aluminum alloy piece. E.g, image 3 with Figure 4 As shown in the example, the first metal layer 10 may be disposed outside the second metal layer 20 (such as image 3 with Figure 4 In the inner and outer directions shown in), the surface of the first metal layer 10 away from the second metal layer 20 may be configured as the outer surface 110 of the housing 100. The first metal layer 10 can choose to use stainless steel parts. The stainless steel parts have high structural strength, which can prevent the terminal 500 from being squeezed, causing deformation of the terminal 500 and affecting the appearance of the product, and even causing damage to the terminal 500, effectively protecting End 500 products. Moreover, the stainless steel piece has higher brightness and metallic texture, and the use of the stainless steel piece for the first metal layer 10 can enhance the appearance of the terminal 500. The second metal layer 20 may be an aluminum alloy piece. Compared with stainless steel pieces, the aluminum alloy piece has a lower density and lighter weight. The use of an aluminum alloy piece for the second metal layer 20 can effectively reduce the overall weight of the housing 100. The second metal layer 20 may be disposed inside the first metal layer 10, and the second metal layer 20 will not affect the overall aesthetics of the housing 100. In addition, the structural strength of the aluminum alloy is relatively low, which facilitates the processing and manufacturing of the internal structure of the housing 100.

[0087] According to an embodiment of the present invention, an antenna slot 60 may be provided on the first metal layer 10. Such as figure 2 As shown in the example, the first metal layer 10 faces the outside of the chamber 70 (such as figure 2 The surface of the inner and outer directions shown in) is configured as the outer surface 110 of the housing 100. An antenna slot 60 may be provided on the first metal layer 10, thereby reducing the signal interference of the metal shell to the terminal 500 and improving the communication transmission performance of the terminal 500.

[0088] According to the method for manufacturing the housing 100 of the terminal 500 according to the embodiment of the present invention, the housing 100 is the housing 100 of the terminal 500 described above, and the manufacturing method includes: stacking the housing made of a first metal material and a second metal material. The blank is processed to form the housing 100. For example, the first metal material can choose a metal material with good hardness and good appearance, and the second metal material can choose a metal material with relatively low density and relatively low hardness. As a result, the housing 100 can have a higher structural strength, and at the same time, the weight of the housing 100 can be reduced.

[0089] According to the method for manufacturing the housing 100 of the terminal 500 according to the embodiment of the present invention, by stacking two different materials of the first metal material and the second metal material into the housing blank and processing the housing 100, different metals can be used. The material properties enhance the overall performance of the housing 100 of the terminal 500. It is not only beneficial to realize the thin and light design of the housing 100 of the terminal 500, but also enables the housing 100 to have sufficient structural strength and aesthetic appearance.

[0090] According to an embodiment of the present invention, such as Figure 7 As shown, the manufacturing method of the housing 100 includes the following sub-steps:

[0091] S10: Select a first blank made of a first metal material and a second blank made of a second metal material, stack and process the first blank and the second blank to form a shell blank, shell The body blank includes a first metal layer 10 and a second metal layer 20, the first metal layer 10 is constructed from the first blank, and the second metal layer 20 is constructed from the second blank.

[0092] S20: Process the shell blank to form the shell 100.

[0093] For example, different metals or alloys can be selected for the first blank and the second blank. For example, the first blank can be stainless steel, and the second blank can be aluminum alloy. First, the stainless steel and aluminum alloy blanks can be processed into plates, and the first and second blank plates can be surface treated, and rolled and compounded into a composite metal layer. The composite metal layer is cut to an appropriate size to produce a shell Body blanks. Then, rough milling, CNC (Computer numerical control machine tools) and other processes are performed on the shell blank to form the shell 100.

[0094] Therefore, the first metal layer 10 and the second metal layer 20 of different materials are selected and rolled into a shell blank, and the shell blank is further processed to form the shell 100. The processing method has simple operation, convenient processing, and high processing precision, which 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 this manufacturing method includes two layers of metal of different materials, which can not only ensure the structural strength and aesthetics of the housing 100, but also reduce the overall weight of the housing 100.

[0095] According to an embodiment of the present invention, such as Picture 8 As shown, after step S20, the following steps can be performed:

[0096] S30: Perform anti-corrosion treatment on the housing 100. It should be noted that the first metal layer 10 and the second metal layer 20 of the housing 100 use two different metal layers. The junction of the first metal layer 10 and the second metal layer 20 is exposed in the air. The moisture and gas composition of the fluoride form a galvanic cell with two different metals, causing electrochemical corrosion of the casing 100. The strong metal active layer of the first metal layer 10 and the second metal layer 20 is prone to lose electrons and cause electrochemical corrosion, which causes corrosion damage to the casing 100 and affects the service life of the casing 100. By performing anti-corrosion treatment on the casing 100, the anti-corrosion ability of the casing 100 can be effectively improved and the service life of the casing 100 can be prolonged.

[0097] Further, the anti-corrosion treatment means can be immersion in anti-corrosion solution, PVD coating, or setting of AF layer. In other words, the casing 100 can be immersed in an anti-corrosion solution for anti-corrosion treatment, or the surface of the casing 100 can be coated with PVD (Physical Vapor Deposition) or an AF layer can be provided. Therefore, after the anti-corrosion treatment, the anti-corrosion performance of the casing 100 can be improved, and the service life of the casing 100 can be prolonged.

[0098] According to an embodiment of the present invention, such as Picture 9 As shown, in step S20, the shell blank is stamped to form the shell 100. In other words, the shell blank can be processed by a stamping process, and the shell blank can be stamped into the shell 100. Therefore, the operation is convenient, and the manufacturing efficiency of the housing 100 can be improved. In other embodiments of the present invention, the shell blank can also be milled into the shell 100. For example, the housing blank can be rough milled first to form the cavity 70 of the housing 100, and then the housing 100 can be finished by CNC to finish milling the inner cavity, outer structure, and outer surface 110, Wait sideways.

[0099] According to an embodiment of the present invention, such as Picture 10 As shown, after step S10, the manufacturing method further includes:

[0100] S101: Machining on the housing blank to form the antenna slot 60. For example, CNC can be used to finish milling the housing 100 to form the antenna slot 60.

[0101] S102: Fill the antenna slot 60 with filler to form a filling layer 610.

[0102] It should be understood that in order to prevent the metal housing 100 from interfering with the signal of the terminal 500, an 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 make the outer surface 110 of the housing 100 flat, so as to improve the aesthetics of the terminal 500.

[0103] Further, the filling layer 610 may be an ink layer or a paint layer. In other words, the antenna groove 60 may be filled with an ink layer, or the antenna groove 60 may be filled with a paint layer. The ink layer and the paint layer have a good insulation effect, which can effectively prevent the formation of interference signals on the housing 100 of the terminal 500, thereby improving the signal transmission capability of the terminal 500. Moreover, the ink layer and the paint layer are adopted, and the materials are cheap and easy to obtain, which can reduce the production cost.

[0104] In some embodiments of the invention, for example, image 3 As shown in the example in, the outer surface 110 of the filling layer 610 may be flush with the surface of the housing 100. As a result, the appearance of the housing 100 can be improved.

[0105] According to an embodiment of the present invention, such as Picture 11 As shown, after step S10, the manufacturing method may further include:

[0106] S11: Machining a functional hole 40 on the shell blank. For example, CNC technology can be used to finish milling the functional hole 40 on the housing 100. The functional hole 40 may be a through hole or a blind hole. For example, the function hole 40 may be a headphone hole, a USB interface, a microphone hole, a side key mounting hole, and the like. Of course, the functional hole 40 may also be a blind hole milled on the housing 100 to prevent mutual interference between the internal structures of the terminal 500.

[0107] Further, in step S11, a laser engraving, CNC, or etching process is used to form the functional hole 40 on the shell blank. In other words, the processing of the functional holes 40 on the shell blank can be performed by a laser engraving process, or a CNC process, and of course, etching or other processing processes can also be used. In the actual processing process, the corresponding processing technology can be selected according to the precision size requirements and the processing cost.

[0108] According to an embodiment of the present invention, such as Figure 3-Figure 6 As shown, the surface of the housing 100 has a connection 30, and the contact between the surface of the first metal layer 10 facing the second metal layer 20 and the second metal layer 20 is configured as the connection 30. It can be understood that the first metal layer 10 and the second metal layer 20 are stacked, and there is a connection 30 at the junction of the first metal layer 10 and the second metal layer 20.

[0109] Such as Picture 12 As shown, after step S10, the manufacturing method may further include:

[0110] S12: A wrapping layer 50 is provided at the joint 30, and the wrapping layer 50 covers the joint 30.

[0111] Thus, the wrapping layer 50 can be used to cover the connection 30, so that the first metal layer 10 and the second metal layer 20 can be prevented from electrochemical corrosion at the connection 30, so as to affect the service life of the casing 100.

[0112] Further, in step S12, injection molding is performed at the joint 30 to form the wrapping layer 50. E.g, Figure 5 As shown in the example shown in the example, a PBT (polybutylene terephthalate) material with good fluidity can form the wrapping layer 50 at the joint 30, and the wrapping layer 50 covers the joint 30. As a result, the corrosion resistance of the casing 100 can be improved, and the service life of the casing 100 can be prolonged.

[0113] In other embodiments of the present invention, in step S12, the recessed portion may be processed at the connection 30 first, and then the wrapping layer 50 may be provided at the connection 30. E.g, image 3 As shown in the example, at the junction of the first metal layer 10 and the second metal layer 20, part of the second metal layer 20 can be removed to form a recess. Can also be like Image 6 As shown in the example, at the junction of the first metal layer 10 and the second metal layer 20, part of the first metal layer 10 and part of the second metal layer 20 are removed at the same time to form a recess, the first metal layer 10 and the second metal layer The junction 30 of the layer 20 is located in the recess. A wrapping layer 50 is arranged in the recess to cover the connection 30. Therefore, the fixed connection between the wrapping layer 50 and the housing 100 is facilitated.

[0114] Further, in step S12, before the wrapping layer 50 is provided, a plurality of spaced grooves may be provided on the surface of the shell blank in contact with the wrapping layer 50. For example, nano-technology can be used to perform nano-hole treatment on the inner surface 210 of the second metal layer 20. Therefore, the connection between the wrapping layer 50 and the casing 100 is facilitated, and the connection strength between the wrapping layer 50 and the casing 100 can be enhanced.

[0115] According to an embodiment of the present invention, the first metal material may be stainless steel, and the second metal material may be aluminum alloy. The structural strength of stainless steel is relatively high, and the appearance of stainless steel is relatively beautiful. The selection of stainless steel as the first metal material can make the housing 100 have sufficient structural strength and high aesthetic appearance. The aluminum alloy has relatively low density and light weight, and the structural strength of the aluminum alloy is low. The aluminum alloy as the second metal material can reduce the weight of the housing 100 and facilitate the processing of the structure of the housing 100.

[0116] The manufacturing method of the housing 100 according to the embodiment of the present invention, such as Figure 13 As shown, the manufacturing method of the housing 100 includes:

[0117] S100: Select the first blank and the second blank, the first blank is a stainless steel part, the second blank is an aluminum alloy part, and the first blank and the second blank are stacked to form a shell blank using a rolling compound method Pieces

[0118] S200: Use a stamping process or a milling process to process the shell blank to form the shell 100;

[0119] S300: Use laser engraving, CNC, or etching processes on the housing 100 to form a functional hole 40;

[0120] S400: Use laser engraving, CNC, or etching processes on the housing 100 to form the antenna slot 60;

[0121] S500: Fill the antenna slot 60 with fillers such as ink or paint layer, and the outer surface of the antenna slot 60 is flush with the surface of the housing 100;

[0122] S600: Cover a layer of wrapping layer 50 at the junction of the first blank and the second blank;

[0123] S700: Carry out anti-corrosion treatment on the shell 100, the anti-corrosion treatment means is soaking in anti-corrosion solution, setting PVD film or AF layer.

[0124] According to the manufacturing method of the shell 100 of the embodiment of the present invention, the first metal layer 10 and the second metal layer 20 of different materials are selected and rolled into shell blanks, and the shell blanks are further processed into shells 100. The processing method has simple operation, convenient processing, and high processing precision, which effectively improves the processing efficiency of the housing 100 of the terminal 500, thereby reducing production costs. Moreover, the housing 100 of the terminal 500 manufactured by this manufacturing method includes two layers of metal of different materials, which can not only ensure the structural strength and aesthetics of the housing 100, but also reduce the overall weight of the housing 100.

[0125] The terminal 500 according to the embodiment of the present invention includes the housing 100 of the terminal 500 described above.

[0126] According to the terminal 500 of the embodiment of the present invention, by providing the above-mentioned housing 100, the metal properties of different metal materials can be utilized to improve the overall performance of the housing 100. On the one hand, the structural strength and appearance of the housing 100 can be effectively improved; the other invention can reduce the weight of the housing 100, which is beneficial to the light and thin design of the housing 100.

[0127] According to the terminal 500 of the embodiment of the present invention, the housing 100 is manufactured by the manufacturing method of the housing 100 described above.

[0128] According to the terminal 500 of the embodiment of the present invention, the first metal layer 10 and the second metal layer 20 of different materials are selected and rolled into a shell blank, and the shell blank is further processed into the shell 100. The processing method has simple operation, convenient processing, and high processing precision, which effectively improves the processing efficiency of the housing 100 of the terminal 500, thereby reducing production costs. Moreover, the housing 100 of the terminal 500 manufactured by this manufacturing method includes two layers of metal of different materials, which can not only ensure the structural strength and aesthetics of the housing 100, but also reduce the overall weight of the housing 100.

[0129] Refer below image 3 , Figure 4 as well as Figure 13 A method for manufacturing the housing 100 of the terminal 500 according to the embodiment of the present invention is described in detail with a specific embodiment.

Preferably, the power supply can be logically connected to the processor through a power management system, so that functions such as management of charging, discharging, and power consumption management are realized through the power management system. Although not shown, the mobile phone may also include a Bluetooth module, sensors (such as a posture sensor, a light sensor, and other sensors such as a barometer, a hygrometer, a thermometer, and an infrared sensor), etc., which are not described here.

[0141] It should be noted that the realization of the functions of the various modules of the mobile phone and the cooperation between the modules need to operate in a safe and stable environment. The various modules and components of the mobile phone can be assembled and installed inside the housing 100 of the mobile phone. Therefore, the housing needs to have sufficient structural strength and long service life, and the housing 100 of the mobile phone is also required to have high aesthetics.

[0142] Such as image 3 As shown, the housing 100 of the terminal 500 includes: a first metal layer 10 and a second metal layer 20. Wherein, the first metal layer 10 may be a stainless steel piece, and the second metal layer 20 may be an aluminum alloy piece. The first metal layer 10 and the second metal layer 20 are stacked, and the thickness of the first metal layer 10 is 0.3 mm, and the thickness of the second metal layer 20 is 0.7 mm.

[0143] The housing 100 of the terminal 500 forms a cavity 70 of the housing 100, and the first metal layer 10 is located outside the cavity 70 (e.g. image 3 The inside and outside directions shown in), the surface of the first metal layer 10 away from the second metal layer 20 is configured as the outer surface 110 of the housing 100; the second metal layer 20 is stacked on the inner side of the first metal layer 10. The surface of the second metal layer 20 away from the first metal layer 10 is configured as the inner surface 210 of the housing 100. Such as image 3 As shown, at the end surface of the housing 100, a portion of the second metal layer 20 is removed to form a recessed portion, and the connection 30 between the first metal layer 10 and the second metal layer 20 is located in the recessed portion. The inner surface 210 of the second metal layer 20 is provided with a plurality of nanoholes at intervals to facilitate the connection and fixation between the wrapping layer 50 and the casing 100. The concave portion is filled with a wrapping layer 50, the wrapping layer 50 is a plastic part, and the wrapping layer 50 covers the joint 30.

[0144] Such as Figure 4 As shown, the housing 100 is provided with a function hole 40, and the function hole 40 may be an earphone hole, a microphone hole, a side key mounting hole, and the like. Such as image 3 As shown, an antenna slot 60 is provided on the first metal layer 10, the antenna slot 60 is filled with a filling layer 610, and the filling layer 610 is an ink layer.

[0145] Such as Figure 13 As shown, the manufacturing method of the housing 100 includes the following steps:

[0146] S100: Select the first blank and the second blank, the first metal layer 10 is a stainless steel part, the thickness of the first metal layer 10 is 0.3mm, the second metal layer 20 is an aluminum alloy part, and the thickness of the second metal layer 20 It is 0.7mm. Processing the first blank and the second blank to form a shell blank, the shell blank being constructed from the first metal layer 10 and the second metal layer 20;

[0147] S200: Use a stamping process or a milling process to process the shell blank to form the shell 100;

[0148] S300: Use laser engraving, CNC, or etching processes on the housing 100 to form a functional hole 40;

[0149] S400: processing on the housing 100 to form an antenna slot 60;

[0150] S500: Fill the antenna slot 60 with fillers such as an ink layer or a paint layer, so that the outer surface 110 of the filler layer 610 is flush with the surface of the housing 100;

[0151] S600: Process the connection part 30 of the superposition of the first metal layer 10 and the second metal layer 20: first process the recess at the connection part 30, and set the surface of the casing 100 in contact with the wrapping layer 50 There are a plurality of spaced grooves, and a wrapping layer 50 is arranged at the joint 30.

[0152] S700: Carry out anti-corrosion treatment on the shell 100, the anti-corrosion treatment means is soaking in anti-corrosion solution, setting PVD film or AF layer.

[0153] Therefore, the first metal layer 10 and the second metal layer 20 of different materials are selected and rolled into a shell blank, and the shell blank is further processed to form the shell 100. The processing method has simple operation, convenient processing, and high processing precision, which effectively improves the processing efficiency of the housing 100 of the terminal 500, thereby reducing production costs. Moreover, the housing 100 of the terminal 500 manufactured by this manufacturing method includes two layers of metal of different materials, which can not only ensure the structural strength and aesthetics of the housing 100, but also reduce the overall weight of the housing 100.
