DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0054] In the description of this application, unless otherwise specified or limited, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0055] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described from the perspectives shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also indirectly connected to the other element "on" or "under" through an intermediate element.

[0056] An electronic device, such as a laptop computer, typically includes a housing, a display screen, a battery, and a circuit assembly. The housing and the display screen are rotatably connected so that the laptop computer can have an unfolded state and a folded state. The battery and the circuit assembly are respectively installed in the housing so that the battery provides power to the entire electronic device, the circuit assembly controls the operation of the entire electronic device, and the display screen displays relevant information.

[0057] With the development of the electronic equipment industry, such as the computer (English full name: computer, abbreviated: PC) industry, the extreme lightness and thinness of PC products has become the mainstream, and the requirements for the utilization rate of the internal structural space of the whole machine have become higher and higher. The process limitations of the products have become more and more obvious, which has increased the difficulty of the product process accordingly. At present, most of the existing laptops are mainly processed by 6 series aluminum plates combined with CNC machine tools (English full name: Computer Numerical Control, abbreviated: CNC). However, the process of combining 6 series aluminum with CNC processing is complex and inefficient. Therefore, in order to simplify the process and improve efficiency, how to achieve the ultimate utilization of structural space and materials and meet the stacking requirements of the whole machine under the conventional 5 series aluminum plate combined with stamping solution has become a focus of PC product structural parts.

[0058] Based on this, this application proposes a PC forming process solution based on 5-series stamped aluminum materials, combining conventional stamping process with stretching process, and optimizing and improving the bottleneck problem, so that it becomes possible to combine 5-series aluminum plates, stamping process and stretching process instead of 6-series aluminum plates and CNC process, which greatly improves the material utilization rate while effectively simplifying the process.

[0059] Among them, 5-series aluminum sheet is composed of an aluminum-magnesium alloy, mainly magnesium, and its main features are excellent tensile strength and elongation, and very light weight. 6-series aluminum sheet is composed of an aluminum-magnesium-silicon alloy, mainly magnesium and silicon, and its main features are medium strength, excellent corrosion resistance, good plasticity, excellent weldability, low cracking, and good cold workability.

[0060] Referring to FIG1 , FIG1 is a perspective view of an electronic device provided by the related art, the electronic device being a laptop computer 100 ′. A laptop computer typically includes a housing 101 ′, a keyboard 102 ′, a touchpad 103 ′, a display screen 104 ′, and circuit components (not shown in the figure). The laptop computer 100 ′ shown in FIG1 includes a borderless touchpad 103 ′, i.e., the touchpad 103 ′ is flush with the frame of the housing 101 ′. In other words, along the width extension direction of the housing 101 ′ (the Y direction in FIG1 ), the touchpad 103 ′ is flush with the housing 101 ′, or in other words, the touchpad 103 ′ is flush with the side 101g ′ of the housing 101 ′.

[0061] The display screen 104' is rotatably connected to the housing 101', allowing the display screen 104' and the housing 101' to be folded and unfolded relative to each other. A keyboard 102' and a touchpad 103' are respectively mounted on the housing 101', allowing input of relevant commands via the touchpad 103' and keyboard 102'. A circuit assembly is disposed within the housing 101' and electrically connected to the keyboard 102', touchpad 103', and display screen 104' for data processing. The display screen 104' is used to display relevant information.

[0062] Referring to Figure 2, Figure 2 is a perspective view of the electronic device shown in Figure 1 without the touchpad. To clearly illustrate the structure of the housing 101', the touchpad 103' is omitted in Figure 2. The housing 101' has a first area 101a' and a second area 101b'. The first area 101a' is provided with a first groove 101e', and the second area 101b' is provided with a second groove 101f', so that the touchpad 103' can be assembled through the first groove 101e' and the second groove 101f'. A sound pickup hole can also be provided inside the housing corresponding to the second area 101b', so that the audio of the laptop computer 100' can be output from the middle of the housing through the sound pickup hole.

[0063] Referring to FIG. 3( a ), FIG. 3( a ) shows the first region 101a′ and the second region 101b′ in FIG. 2 , before the grooves are formed. In other words, in FIG. 3( a ), the first groove 101e′ and the second groove 101f′ have not yet been formed. At this point, the overall thickness of the housing 101′ is 2.5 mm.

[0064] Referring to Figure 3(b), Figure 3(b) is a schematic diagram of a bent portion formed on the basis of Figure 3(a). In Figure 3(b), the shell 101' can be bent in the Y direction to form a bent portion 101c' through a bending process. The bent portion 101c' can also be called a flange. The flange is mainly used for mutual connection and matching between stamping parts, such as welding, riveting, bonding, and snapping. In this embodiment, the laptop computer 100' also includes a bottom shell, which can be assembled on the side of the shell 101' facing away from the keyboard 102', and the side of the bottom shell is connected with the bent portion 101c', so that the bent portion 101c' can be covered.

[0065] Referring to Figure 3(c), Figure 3(c) is a schematic diagram of forming the first groove 101e' based on Figure 3(b). In Figure 3(c), the first groove 101e' can be formed in the first area 101a' of the shell 101' by stamping. The depth of the first groove 101e' is 1 mm, and the sum of the shell thickness corresponding to the first area 101a' and the depth of the first groove 101e' is 3.5 mm.

[0066] Referring to FIG3(d), FIG3(d) is a schematic diagram of forming a second groove 101f' based on FIG3(c). In FIG3(d), the second groove 101f' can be formed by cutting in the second area 101b' of the housing 101'. The depth of the second groove 101f' is 1 mm, so that the touch panel 103' can be installed in the first groove 101e' and the second groove 101f'. At this time, since the second area 101b' is cut off by 1 mm, the shell thickness corresponding to the second area 101b' is only 1.5 mm. It should be noted here that since the touch panel has a borderless design, a second groove 101f' is required in the second area 101b' for assembling the touch panel. However, due to the presence of the bent portion 101c', the second groove 101f' cannot be formed in the second area 101b' using a stamping process, so a cutting process is used to form the second groove 101f'.

[0067] Referring to Figure 3(e), Figure 3(e) is a schematic diagram of forming the sound pickup hole 101d' based on Figure 3(d). In this process step, the sound pickup hole 101d' can be opened in the second area 101b' by a drilling process. The diameter of the sound pickup hole 101d' is usually 0.8 mm. As mentioned above, after the second groove 101f' is formed in the second area 101b' by cutting, the shell thickness corresponding to the second area 101b' is only 1.5 mm, so that only 0.35 mm is left on the upper and lower sides of the sound pickup hole 101d'.

[0068] To prevent the housing 101' from breaking, a thickness of at least 0.4 mm must be left above and below the sound pickup hole 101d' to ensure that the housing 101' does not break. Therefore, after the cutting process used in the related art to form the second groove 101f', the remaining thickness cannot meet the required opening requirements for the sound pickup hole. The electronic device and its housing provided by the embodiments of the present application can solve this technical problem.

[0069] 4 is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. The embodiment of the present application discloses an electronic device 100, which includes a housing 1, a bottom housing (not shown), a touchpad 2, a keyboard 3, a circuit assembly (not shown), and a display screen 4.

[0070] The housing 1 is generally rectangular, with a bottom housing covering the bottom of the housing 1. The circuit assembly is housed within the housing 1. The touchpad 2 and keyboard 3 are separately mounted on the housing 1 and electrically connected to the circuit assembly. The display 4 is rotatably connected to the housing 1, allowing the display 4 and housing 1 to be folded or unfolded. The display 4 is also electrically connected to the circuit assembly. During operation, the display 4 is unfolded, and commands can be input via the touchpad 2 and keyboard 3. The circuit assembly processes the commands, which are then displayed on the display 4.

[0071] Referring to Figure 5 , Figure 5 is a schematic structural diagram of the housing shown in Figure 4 . The housing 1 comprises a main body 11 and a bent portion 12. The main body 11 defines a mounting cavity within which the circuit assembly is mounted. The housing 1 comprises a side 1a, which is bent 70° to 90° toward the side facing away from the touchpad 2, thereby forming the bent portion 12. In the embodiment shown in Figure 5 , the bottom housing is omitted, thereby exposing the bent portion 12. After the bent portion 12 is mated and connected to the bottom housing, the bottom housing covers the bent portion 12. In this embodiment, the housing 1 can be made of 5-series aluminum sheet.

[0072] Continuing with FIG5 , the main body 11 comprises a first area 111, a second area 112, a third area 113, and a fourth area 114. The fourth area 114, the third area 113, and the first area 111 are sequentially arranged along the width of the housing 1 (the Y direction in FIG5 ). The second area 112 is located on both sides of the third area 113 and the first area 111. The touchpad 2 is mounted in the third area 113 and the first area 111, and the keyboard 3 is mounted in the fourth area 114.

[0073] FIG6 is a partial structural diagram of the housing shown in FIG5 , with the touchpad omitted. A first groove 13 is provided on one side of the first region 111, and a second groove 15 is provided on one side of the third region 113. Both first and second grooves 13 and 15 are located on the same side of the housing 1 facing away from the bent portion 12. One end of the first groove 13 extends to the location of the bent portion 12, and the other end of the first groove 13 extends to the second groove 15. The touchpad 2 is mounted in the first and second grooves 13 and 15.

[0074] Figure 7 is a schematic diagram of the structure of the housing in Figure 5 from another perspective. A first protrusion 14 is provided on the other side of the first area 111, that is, the first protrusion 14 and the first groove 13 are located on both sides of the first area 111, away from each other. A second protrusion 16 is provided on one side of the third area 113, that is, the second protrusion 16 and the second groove 15 are located on both sides of the third area 113, away from each other. The bent portion 12 bends and extends in the direction in which the first protrusion 14 and the second protrusion 16 protrude. One end of the first protrusion 14 extends to the bent portion 12, and the other end of the first protrusion 14 extends to the second protrusion 16. The sound pickup hole 17 is opened in the first protrusion 14 and extends to the bent portion 12.

[0075] During the specific manufacturing process, the second groove 15 and the second protrusion 16 can be formed by stamping, and then the first groove 13 and the first protrusion 14 can be formed by stretching. After forming the first groove 13, the first protrusion 14, the second groove 15, and the second protrusion 16, they can be trimmed according to actual needs to fine-tune the depth of the first groove 13 and the second groove 15 and the height of the second protrusion 16. For example, if the second protrusion 16 protrudes too long to meet the required depth of the second groove 15, the second protrusion 16 can be appropriately trimmed. If the depth of the first groove 13 and the second groove 15 is insufficient to accommodate the touchpad, the first groove 13 and the second groove 15 can be appropriately trimmed to meet the required depth.

[0076] In the present application, a stamping process is used to form the second groove 15 and the second protrusion 16 in the third area 113, and a stretching process is used to form the first groove 13 and the first protrusion 14 in the first area 111 near the bending portion 12. The stamping process is combined with the stretching process to meet the depth requirement of the touch panel groove (the touch panel groove refers to the groove used to install the touch panel) and the thickness requirement of the sound pickup hole opening area.

[0077] Referring to Figure 8 , which is a cross-sectional view taken at point AA in Figure 6 , Figure 8 shows the state after the second groove is formed on the housing. In the third region 113, the second groove 15 and the second protrusion 16 are first formed by stamping. At this point, the housing thickness corresponding to the third region 113 is 2.5 mm. No stamping or stretching is performed on the second region 112, which remains in its original state. At this point, the housing thickness corresponding to the second region 112 is also 2.5 mm, and the housing thicknesses in the second and third regions 112 and 113 are the same.

[0078] Refer to Figure 9, which is a cross-sectional view taken at point BB in Figure 6. In the previous step, a second groove 15 with a depth of 1 mm and a second protrusion 16 with a protrusion distance of 1 mm were formed, resulting in a shell thickness corresponding to the third region 113 and the depth of the second groove 15 totaling 3.5 mm. Subsequently, as shown in Figure 9, a first groove 13 with a depth of 1 mm and a first protrusion 14 with a protrusion distance of 1 mm were formed in the first region 111 by stretching, resulting in a shell thickness corresponding to the first region 111 totaling 3.5 mm. At this point, the shell thickness corresponding to the first region 111 remains at 2.5 mm. If a 0.8 mm sound pickup hole 17 is provided in the first region 111, a 0.85 mm shell thickness can be added above and below the sound pickup hole 17, fully satisfying the requirements for the sound pickup hole 17.

[0079] Of course, in some embodiments, in order to better adapt to the thickness of the touch panel 2, the first groove 13 and the second groove 15 can be appropriately cut to fine-tune the depth of the first groove 13 and the second groove 15, and in order to adapt to the bottom plate, the bent portion 12 can also be appropriately cut.

[0080] Referring to Figure 10 , which is a partial enlarged view of the housing in Figure 6 , to facilitate opening the display screen 4, the bent portion 12 is provided with a latch 121. This latch 121 is located in the middle of the side 1a of the housing 1, that is, approximately in the middle of the longitudinal extension direction of the housing 1 (the X direction in Figure 5 ). This latch 121 is actually a depression in the bent portion 12 toward the keyboard.

[0081] Referring to FIG11 , FIG11 is a partial enlarged view of the housing provided in an embodiment of the present application. The position of the first protrusion 14 corresponds to the position of the hand-holding position 121, thereby ensuring that the audio of the electronic device can be output from the middle of the housing. In this embodiment, the width of the first protrusion 14 is less than or equal to the width of the hand-holding position 121. In FIG11 , the width of the first protrusion 14 is L1, the width of the hand-holding position 121 is L2, and L1 is L2. <L2。

[0082] In this embodiment, the first protrusion 14 and the second protrusion 16 are protruding compared to the shell at the second area 112, and the outer surfaces of the first protrusion 14 and the second protrusion 16 are arranged flush, and the first protrusion 14 has an oblique side surface 141, and the angle between the oblique side surface 141 and the second area 112 is α, 15°≤α≤20°, that is, the first area 111 adopts oblique angle stretching, and the stretching angle is 15°~20°. The distance between the second protrusion 16 and the bent portion 12 is W, W≥3mm. In this embodiment, by setting the distance between the second protrusion 16 and the bent portion 12 to be greater than or equal to 3mm, a pressing space is reserved to facilitate stamping. Of course, in other embodiments, the first protrusion 14 and the second protrusion 16 may also be arranged unevenly. For example, after the second groove 15 and the second protrusion 16 are formed by stamping, the second protrusion can be cut off by cutting.

[0083] In other embodiments, the width of the first protrusion 14 may be greater than the width of the handle portion 121. Specifically, the width of the first protrusion 14 may be greater than the width of the handle portion 121 but less than the width of the second protrusion 16, as shown in FIG12 ; or the width of the first protrusion 14 may be greater than the width of the second protrusion 16, as shown in FIG13 . This embodiment prevents the housing from breaking by making the width of the first protrusion 14 greater or less than the width of the second protrusion 16. This is because if the width of the first protrusion 14 is equal to the width of the second protrusion, the stretched side and the stamped side are flush and connected, and the connection between the two is prone to breaking.

[0084] This application is based on 5 series aluminum plates, and adopts a stamping method to achieve partial lowering of the 5 series aluminum plates to avoid forming a touch panel groove. At the same time, a stretching process is adopted to achieve partial convexity at the bending position to ensure the required aluminum plate thickness for setting the pickup hole 17. Ultimately, it solves the problem that the side wall flange position of the shell cannot be half-cut and the shell thickness at the hand-hook position 121 is insufficient, making it impossible to set the pickup hole 17. The 5 series aluminum plate forming process successfully replaces the 6 series aluminum plate CNC processing process.

[0085] Based on the above embodiments, an embodiment of the present application further discloses a method for manufacturing a housing of an electronic device. As shown in FIG14 , the method for manufacturing the housing includes the following steps:

[0086] S11, processing the shell into a preset shape.

[0087] Specifically, as shown in Figure 15(a), the shell 1 is processed into a preset shape. At this time, the overall thickness of the shell 1 is 2.5 mm. The shell 1 has a first area 111, a second area 112, a third area 113 and a fourth area 114. The fourth area 114, the third area 113 and the first area 111 are distributed in sequence along the width extension direction of the shell 1, and the second area 112 is located on both sides of the third area 113 and the first area 111.

[0088] S12, bending the side of the shell having a preset shape to form a main body portion and a bent portion.

[0089] Specifically, as shown in FIG15( b ), the side of the housing 1 can be bent 70° to 90° to form a bent portion 12, resulting in the housing 1 comprising a main body 11 and a bent portion 12. In this case, the thickness of the main body 11 is 2.5 mm. To facilitate opening the display screen, the bent portion 12 can be processed to form a handle 121. For example, the handle 121 can be formed at a corresponding position on the bent portion 12 by CNC machining.

[0090] S13. Form a second groove and a second protrusion in the third area of ​​the main body by stamping.

[0091] Specifically, as shown in FIG15( c ), a second groove 15 with a depth of 1 mm and a second protrusion 16 with a protrusion distance of 1 mm can be formed in the third area 113 of the main body 11 by stamping. In this case, the thickness of the outer shell 1 corresponding to the third area 113 is 2.5 mm, and the thickness of the outer shell 1 corresponding to the first area 111 is 2.5 mm.

[0092] In some embodiments, after the second groove 15 and the second protrusion 16 are formed in the third area 113 of the main body 11 by stamping, part of the second protrusion 16 can be cut off by cutting to increase the internal space of the shell; or, the second groove 15 can be cut by cutting to make the depth of the second groove 15 more suitable for the touch panel.

[0093] S14. Form a first groove and a first protrusion in the first area of ​​the main body by stretching.

[0094] Specifically, as shown in FIG15( d ), the first region 111 of the main body 11 can be stretched to form a first groove 13 with a depth of 1 mm and a first protrusion 14 with a protrusion distance of 1 mm. One end of the first groove 13 extends to the second groove 15, and the other end of the first groove 13 extends to the bent portion 12. One end of the first protrusion 14 extends to the second protrusion 16, and the other end of the first protrusion 14 extends to the second protrusion 16. The position of the first protrusion 14 is set to correspond to the position of the hand-engaging position 121. In this case, the thickness of the shell 1 corresponding to the first region 111 is 2.5 mm, and the thickness of the shell 1 corresponding to the third region 113 is 2.5 mm.

[0095] In some embodiments, after the first area 111 of the body 11 is stretched to form the first groove 13 and the first protrusion 14, the first groove 13 may be cut to make the depth of the first groove 13 more suitable for the touch panel.

[0096] S15, opening a sound pickup hole in the first protrusion, extending the sound pickup hole to the bent portion.

[0097] Specifically, as shown in Figure 15(e), a sound pickup hole 17 with a diameter of 0.8 mm can be opened at the shell corresponding to the first area 111. At this time, the thickness of the shell above and below the sound pickup hole 17 can also reach 0.85 mm, meeting the requirements for opening the sound pickup hole 17.

[0098] This application is based on 5 series aluminum plate. In the third area 113 of the shell 1, a stamping process is used to form a second groove 15 that meets the touch panel groove depth requirement. In the first area 111 near the bending part 12, a stretching process is used to form a first protrusion that meets the microphone pickup channel shell thickness requirement. This solves the problem that the flange position of the shell side wall cannot be half-cut and the hand-holding position 121 is not thick enough to set the pickup hole 17, and successfully realizes the 5 series aluminum plate forming process instead of the 6 series aluminum plate CNC processing process.

[0099] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art of the present embodiment within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
