[0011] This allows for the restriction of the relative position between the first and second housings in the vertical direction.

[0012] In some embodiments, the second housing includes a cover, a support, and two connecting portions connected together; the cover covers the opening; the support is connected to the cover, and the circuit board assembly is detachably connected to the support; the two connecting portions are respectively connected to opposite sides of the cover, and one connecting portion is disposed corresponding to a first sidewall, and the connecting portion abuts against a limiting portion on the corresponding first sidewall.

[0067] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0068] Generally, a computer host includes a casing, a motherboard, and functional modules mounted on the motherboard. The functional modules are mounted on the motherboard using screws or other threaded fasteners, and the motherboard is connected to the casing using screws or other threaded fasteners. Similarly, all connections between casings are made using screws or other threaded fasteners. However, assembling a computer host requires additional tools, making the assembly process cumbersome and inefficient.

[0069] Therefore, this application provides a computer host in which the front shell and middle shell of the first housing are snapped together, the middle shell and second housing are snapped together, the circuit board assembly is snapped together with the second housing, and the functional modules in the circuit board assembly are snapped together with the motherboard. Compared with the connection method using screws or other threaded fasteners in related technologies, the computer host can be assembled without the need for third-party tools. This makes the assembly steps of the computer host provided by this application embodiment simpler and more efficient.

[0070] It should be noted that the computer host provided in this embodiment includes, but is not limited to, a mini personal computer (mini PC). No specific limitation is made here regarding the type of computer host provided in this embodiment.

[0071] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0072] Please see Figures 1 to 3 , Figure 1 This is an exploded view of a computer host provided in an embodiment of this application. Figure 2 This is a three-dimensional structural diagram of the computer host provided in an embodiment of this application. Figure 3 This is a three-dimensional structural diagram of a computer host provided in an embodiment of this application from another perspective. As shown in the figure, this embodiment provides a computer host 10, including a first housing 1, a second housing 2, and a circuit board assembly 3.

[0073] The first housing 1 includes a front shell 11 and a middle shell 12 connected together. The front shell 11 and the middle shell 12 enclose a mounting groove 13 with an opening 131 formed by the middle shell 12. The front shell 11 is disposed opposite to the opening 131, and the front shell 11 and the middle shell 12 are engaged together. Thus, compared with the connection method using screws or other threaded fasteners in related technologies, the engagement connection between the front shell 11 and the middle shell 12 simplifies the connection steps and improves the assembly efficiency.

[0074] Regarding the snap-fit ​​connection between the front shell 11 and the middle shell 12, one of the front shell 11 and the middle shell 12 may have a snap-fit ​​protrusion 14 and the other may have a snap-fit ​​hole 15. The snap-fit ​​protrusion 14 and the snap-fit ​​hole 15 are engaged to snap-fit ​​the front shell 11 and the middle shell 12.

[0075] For specific details, please refer to... Figures 4 to 6 , Figure 4 This is a three-dimensional structural diagram of the front shell of a computer host provided in an embodiment of this application. Figure 5 This is a three-dimensional structural diagram of the middle shell in a computer host provided in an embodiment of this application. Figure 6 This is a three-dimensional structural diagram of the middle shell of the computer host provided in an embodiment of this application from another perspective. As shown in the figure, in some specific embodiments, the front shell 11 includes a panel 111 and a plurality of snap-fit ​​protrusions 14 connected to the inner side of the panel 111. The panel 111 can integrate buttons 4 and light guide pillars 5. That is, the panel 111 can be provided with button holes 1111 for mounting buttons 4 and light guide holes 1112 for light guide pillars 5 to extend out. The snap-fit ​​protrusions 14 include a connecting plate 141 and snap-fit ​​protrusions 142. The connecting plate 141 is perpendicular to the panel 111, and the snap-fit ​​protrusions 142 are connected to the end of the connecting plate 141 and protrude upward or downward. It can be understood that if snap-fit ​​protrusions 14 are provided at both the top and bottom of the panel 111 and corresponding snap-fit ​​holes 15 are provided inside the middle shell 12, the connection reliability between the front shell 11 and the middle shell 12 will be improved.

[0076] Please continue to combine Figures 7 to 10 , Figure 7 This is a schematic diagram of the planar structure of a computer host provided in an embodiment of this application. Figure 8 for Figure 7 Cross-sectional view along the AA direction. Figure 9 for Figure 8 A magnified view of the local structure at point B. Figure 10 for Figure 8 A magnified view of the partial structure at point C. Therefore, in this embodiment, the top and bottom of the panel 111 are provided with a plurality of snap-fit ​​protrusions 14 spaced apart along the width direction of the computer host 10. The snap-fit ​​protrusions 142 in the snap-fit ​​protrusions 14 at the top point protrude upwards, and the snap-fit ​​protrusions 142 in the snap-fit ​​protrusions 14 at the bottom point protrude downwards. Correspondingly, in the middle shell 12, the bottom of the snap hole 15 at the top point extends upwards, and the bottom of the snap hole 15 at the bottom point extends downwards.

[0077] There can be three snap-fit ​​protrusions 14 at both the top and bottom of the panel 111. In other embodiments, the number of snap-fit ​​protrusions 14 can also be two, four, five, etc. Here, there is no specific limitation on the number of snap-fit ​​protrusions 14.

[0078] It should be noted that the snap-fit ​​engagement between the snap-fit ​​protrusion 14 and the snap-fit ​​hole 15 is used to restrict the position of the face shell 11 and the middle shell 12 in the width and length directions of the computer host 10. As for the relative position in the vertical direction, it relies on the engagement between the opening on one side of the middle shell 12 and the face shell 11.

[0079] In this embodiment, the middle shell 12 includes two first sidewalls 132 and two second sidewalls 133 for defining the mounting groove 13. The two first sidewalls 132 are arranged relatively spaced along the width direction of the computer host 10, and the two second sidewalls 133 are arranged relatively spaced along the vertical direction. The two second sidewalls 133 are connected between the two first sidewalls 132 to enclose and form an opening 131, and the aforementioned card hole 15 is opened on the two second sidewalls 133.

[0080] Regarding the aforementioned directional limitations, please refer to [link / reference]. Figures 1 to 7 Among them, the up and down directions are Figures 1 to 7 The vertical direction is consistent, and the width direction of the computer host 10 is consistent with... Figures 1 to 7 The y-axis direction is consistent with the length direction of the computer host 10. Figures 1 to 3 , Figures 5 to 6 The x-axis direction is consistent with the x-axis direction.

[0081] Furthermore, a portion of the second housing 2 is inserted into the mounting groove 13 through an opening 131, and the second housing 2 is snapped into the first housing 1 to form a mounting cavity 6. The circuit board assembly 3 is located within the mounting cavity 6 and is detachably connected to the second housing 2. Thus, by snapping the second housing 2 into the first housing 1, the assembly steps between the first housing 1 and the second housing 2 are simplified, thereby improving the assembly efficiency between the first housing 1 and the second housing 2, and consequently improving the assembly efficiency of the computer host 10 provided in this embodiment.

[0082] The second housing 2 is inserted into the middle housing 12 and engaged with the middle housing 12.

[0083] Please combine Figure 11 , Figure 11 This is a three-dimensional structural diagram of the second housing in a computer host provided in an embodiment of this application. As shown in the figure, the second housing 2 includes a cover portion 21, a support portion 22, and two connecting portions 23 connected together; the cover portion 21 covers the opening 131; the support portion 22 is connected to the cover portion 21, and the circuit board assembly 3 is detachably connected to the support portion 22; the two connecting portions 23 are respectively connected to opposite sides of the cover portion 21, and each connecting portion 23 is provided corresponding to a first sidewall 132.

[0084] Understandably, the circuit board assembly 3 generates a significant amount of heat during the operation of the computer host 10. Therefore, heat dissipation holes 211 can be provided on the cover 21 to connect the mounting cavity 6 with the external environment. In this way, the heat generated by the circuit board assembly 3 can be dissipated through the heat dissipation holes 211, thereby cooling the computer host 10.

[0085] In order to improve the heat dissipation effect, in some embodiments, the above-mentioned heat dissipation holes 211 are arranged in multiple intervals on the cover portion 21. Here, there is no specific limitation on the number and arrangement of the heat dissipation holes 211.

[0086] Furthermore, in some embodiments, the connecting portion 23 may include a first connecting segment 231 and a second connecting segment 232 connected together, wherein the first connecting segment 231 is connected to the cover portion 21, the second connecting segment 232 is connected to the side of the first connecting segment 231 near the face shell 11, and the dimension of the second connecting segment 232 in the vertical direction is smaller than the dimension of the first connecting segment 231 in the vertical direction.

[0087] It is understood that if the position between the first housing 1 and the second housing 2 can be limited and the insertion direction of the second housing 2 can be restricted during the assembly process of the first housing 1 and the second housing 2, the assembly efficiency of the first housing 1 and the second housing 2 can be further improved, thereby improving the assembly efficiency of the computer host 10 provided in the embodiments of this application.

[0088] Therefore, please continue to combine Figures 12 to 14 , Figure 12 This is a schematic diagram of the computer host provided in an embodiment of this application from another perspective. Figure 13 for Figure 12 Cross-sectional view along the DD direction. Figure 14 for Figure 13 A magnified view of the partial structure at point E. A guide limiting structure 7 is provided between the first housing 1 and the second housing 2. The guide limiting structure 7 is used to limit the relative position between the first housing 1 and the second housing 2 and to limit the insertion direction of the second housing 2. Specifically, the guide limiting structure 7 is located between the middle housing 12 and the second housing 2. This further improves the assembly efficiency between the first housing 1 and the second housing 2.

[0089] In some alternative embodiments, the guide limiting structure 7 may include two limiting parts 71, which are respectively disposed on two opposite groove walls of the mounting groove 13; wherein the second housing 2 is restricted between the two limiting parts 71 and a portion of the groove wall of the mounting groove 13.

[0090] Specifically, two limiting parts 71 are respectively disposed on the two first side walls 132, the second housing 2 is located between the limiting parts 71 and a second side wall 133, and the connecting part 23 abuts against the limiting part 71 on the corresponding first side wall 132. In this way, the relative position between the middle housing 12 and the second housing 2 can be limited in the vertical direction.

[0091] It is understandable that during the manufacturing process of the middle shell 12 and the second shell 2, there may be some error between the dimensions of the middle shell 12 and the second shell 2 and the designed preset dimensions. When the error exists, if the middle shell 12 and the second shell 2 are assembled, the second shell 2 may shake inside the middle shell 12. In order to avoid this phenomenon to a certain extent, the guide limiting structure 7 provided in this embodiment also includes a first support protrusion 72 and a second support protrusion 73. The first support protrusion 72 is disposed on the side of the connecting part 23 facing the first sidewall 132. Specifically, the first support protrusion 72 is disposed on the side of the first connecting section 231 facing the first sidewall 132, and the first support protrusion 72 abuts against the first sidewall 132. The second support protrusion 73 is disposed on the side of the support part 22 away from the circuit board assembly 3, and the second support protrusion 73 abuts against the second sidewall 133. In this way, whether in the vertical direction or in the width direction of the computer host 10, the shaking of the second shell 2 caused by processing errors can be avoided to a certain extent, thereby improving the stability of the computer host 10 provided in this embodiment and making the computer host 10 provided in this embodiment perform better.

[0092] The second support protrusion 73 mentioned above can be set in multiple intervals along the width direction of the computer host 10, so that the stability of the second housing 2 at various points along the width direction of the computer host 10 is better.

[0093] It should be noted that the extension directions of the first support protrusion 72 and the second support protrusion 73 are both consistent with the length direction of the computer host 10, and the extension length of the first support protrusion 72 is equal to the extension length of the first connecting segment 231 in this direction, and the extension length of the second support protrusion 73 in the length direction of the computer host 10 is equal to the extension length of the support portion 22 in this direction.

[0094] As described above, the first shell 1 and the second shell 2 are engaged and connected together; specifically, the middle shell 12 is engaged and connected to the second shell 2. In this embodiment, to improve the connection reliability between the middle shell 12 and the second shell 2, the middle shell can be connected to both the top and bottom of the second shell 2.

[0095] Therefore, please combine Figures 15 to 16 , Figure 15 for Figure 7 A cross-sectional view along the FF direction. Figure 16 for Figure 15 A magnified schematic diagram of the local structure at point G. Figure 17 for Figure 15 A magnified view of the partial structure at point H. As shown in the figure, the snap-fit ​​between the top of the second housing 2 and the first housing 1 can be a snap-fit ​​between the cover part 21 and the middle housing 12. Specifically, one of the cover part 21 and the first housing 1 is provided with a buckle 8, and the other is provided with a slot 9. The buckle 8 and the slot 9 engage to snap-fit ​​and connect the top of the cover part 21 and the middle housing 12.

[0096] Specifically, the buckle 8 is located on the inner side of the cover portion 21, and the slot 9 is opened on the second side wall 133 at the top. The opening of the slot 9 is set downwards, and the buckle 8 includes a support section 81 and a snap-fit ​​section 82. The support section 81 is connected to the cover portion 21, and the snap-fit ​​section 82 is located at the top of the support section 81 and extends into the slot 9 to snap-fit ​​with the slot 9, so as to snap-fit ​​the top of the cover portion 21 and the middle shell 12.

[0097] It is understandable that in order to place the computer host 10 stably on a desktop or other surface, a foot pad or similar device is provided at the bottom of the computer host 10. However, traditional foot pads only have a supporting function and cannot serve a connecting function. Therefore, in an optional embodiment, the structure of the foot pad can be improved so that the bottom of the cover 21 and the middle shell 12 can be engaged and connected together through the foot pad.

[0098] Therefore, the computer host 10 provided in this embodiment also includes a support pad 20. A portion of the support pad 20 is exposed outside the first housing 1, that is, a portion of the support pad 20 is exposed outside the bottom of the middle housing 12, and another portion passes through the shell wall of the first housing 1 and is engaged with the second housing 2. Specifically, the other portion of the support pad 20 passes through the shell wall of the middle housing 12 and is engaged with the support part 22. In this way, the support pad 20 not only provides support for the computer host 10 and improves the overall stability of the computer host 10, but also enables the support pad 20 to engage and connect the support part 22 with the middle housing 12.

[0099] Please continue to combine Figure 18 , Figure 18 This is a three-dimensional structural diagram of the support pad in a computer host provided in an embodiment of this application. In some specific embodiments, the support pad 20 includes a support body 201, a transition portion 202, and a snap-fit ​​portion 203 connected together. The transition portion 202 is connected between the support body 201 and the snap-fit ​​portion 203. The support body 201 is exposed at the bottom of the middle shell 12. The middle shell 12 and the support portion 22 are respectively provided with a first through hole 121 and a second through hole 221 for the transition portion 202 to pass through. The snap-fit ​​portion 203 snaps into the second shell 2.

[0100] The support body 201 has a circular cross-section, and its top has two spaced transition portions 202, each corresponding to a snap-fit ​​portion 203. The transition portions 202 extend vertically and are constructed as arc-shaped plates horizontally. The snap-fit ​​portions 203 are connected to the top of the corresponding transition portions 202 and extend in a direction away from the other transition portion 202. The snap-fit ​​portions 203 are also constructed as arc-shaped plates horizontally. Furthermore, the dimensions of the transition portions 202 are larger than those of the support body 201 and the snap-fit ​​portions 203 in the vertical direction.

[0101] Thus, by setting two spaced transition portions 202 and snap-fit ​​portions 203, the deformation of the support pad 20 can be increased to improve the assembly efficiency of the support pad 20 connecting the first housing 1 and the second housing 2, and the connection reliability between the support portion 22 and the middle housing 12 can be improved.

[0102] It should be noted that, in order for the snap-fit ​​portion 203 and the support portion 22 to snap together, the partial outline shape of the first through hole 121 and the second through hole 221 can be consistent with the partial outline shape of the snap-fit ​​portion 203, and the size of the first through hole 121 and the second through hole 221 should be larger than the outline size of the snap-fit ​​portion 203.

[0103] Furthermore, in this embodiment, the bottom surface of the middle shell 12 is rectangular. In order to further improve the stability of the computer host 10 and improve the connection reliability between the middle shell 12 and the second shell 2, four support pads 20 can be provided, which are respectively located at the four corners of the bottom of the middle shell 12.

[0104] To improve the assembly efficiency between the circuit board assembly 3 and the second housing 2, in some optional embodiments, the circuit board assembly 3 includes a main board 31, which is snap-fitted together with the second housing 2. This snap-fit ​​connection method results in higher assembly efficiency between the circuit board assembly 3 and the second housing 2.

[0105] For specific details, please refer to... Figures 19 to 22 , Figure 19 This is a schematic planar structure diagram of the second housing and circuit board assembly in a computer host provided in an embodiment of this application. Figure 20 for Figure 19 Sectional view along direction II, Figure 21 for Figure 20 A magnified view of the local structure at point J. Figure 22 for Figure 11 A magnified view of the partial structure at point K. As shown, a protrusion 24 is provided on the side of the support portion 22 facing the motherboard 31. The motherboard 31 has a snap-fit ​​hole 311, and the protrusion 24 passes through the snap-fit ​​hole 311 and abuts against the side of the motherboard 31 opposite to the support portion 22. In this way, the snap-fit ​​connection between the protrusion 24 and the snap-fit ​​hole 311 can realize the snap-fit ​​connection between the motherboard 31 and the support portion 22, thereby improving the assembly efficiency between the circuit board assembly 3 and the second housing 2.

[0106] It should be noted that, in the length direction of the computer host 10, one end of the circuit board assembly 3 away from the cover 21 is located on the side of the second housing 2 near the front shell 11. In this embodiment, this end of the circuit board assembly 3 can abut against the front shell 11 to limit the position of the circuit board assembly 3 in the length direction of the computer host 10.

[0107] More specifically, the protrusion 24 includes a columnar body 241, a reinforcing plate 242, and a snap-fit ​​connector 243. The columnar body 241 is connected to the support 22. Two reinforcing plates 242 are provided and are located on both sides of the columnar body 241 along its radial direction. The snap-fit ​​connector 243 is connected to the top of the columnar body 241. That is, the snap-fit ​​connector 243 is formed at one end of the protrusion 24 away from the support 22, and the edge of the snap-fit ​​connector 243 is located outside the edge of the columnar body 241. The size of the snap-fit ​​connector 243 gradually decreases in the direction away from the columnar body 241.

[0108] Please continue to combine Figure 23 , Figure 23This is a three-dimensional structural diagram of a partial structure of the circuit board assembly in a computer host provided in an embodiment of this application. As shown, the snap-fit ​​hole 311 includes a first hole segment 3111 and a second hole segment 3112 that are connected. The diameter of the first hole segment 3111 is larger than the diameter of the second hole segment 3112. The snap-fit ​​connector 243 can pass through the second hole segment 3112 and move from the position of the second hole segment 3112 to the position of the first hole segment 3111 to abut against the side of the motherboard 31 away from the second housing 2. That is, when snapping the circuit board assembly 3 to the second housing 2, the snap-fit ​​connector 243 is first made to pass through the first hole segment 3111 and abut against the upper end of the motherboard 31. Then, the circuit board assembly 3 is moved towards the second hole segment 3112 so that the columnar body 241 fits against the hole wall of the first hole segment 3111, thereby making the snap-fit ​​connector 243 snap-fit ​​with the second hole segment 3112. Only in this way can the circuit board assembly 3 and the second housing 2 be snap-fitted together.

[0109] Furthermore, in order to reduce the weight of the second housing 2 and to facilitate the deformation of the protrusion 24 to connect the second housing 2 to the circuit board assembly 3, in some optional embodiments, a cavity 244 is formed within the protrusion 24. The cavity 244 penetrates the columnar body 241 and the snap-fit ​​connector 243, and a deformation notch 245 can be formed on opposite sides of the sidewall of the columnar body 241, and the deformation notch 245 connects the cavity 244 to the external environment. In this way, on the one hand, the weight of the second housing 2 can be reduced, and on the other hand, the deformation amount of the protrusion 24 can be increased, thereby further improving the assembly efficiency between the circuit board assembly 3 and the second housing 2.

[0110] It is understood that the motherboard 31 is typically rectangular. To improve the reliable connection between the circuit board assembly 3 and the second housing 2, multiple protrusions 24 and corresponding snap-fit ​​holes 311 can be provided. In this case, there can be four snap-fit ​​holes 311, which are distributed at the four corners of the motherboard 31. In some other embodiments, the number of protrusions 24 and snap-fit ​​holes 311 can be other than those specified here.

[0111] Of course, the computer host 10 mainly relies on the electrical components installed on the motherboard 31 during operation. Therefore, the circuit board assembly 3 also includes a functional module 32 disposed on the side of the motherboard 31 opposite to the second housing 2. The functional module 32 is connected to the motherboard 31 by a fastener 30. In this way, connecting the functional module 32 and the motherboard 31 by a fastener can improve the assembly efficiency between the functional module 32 and the motherboard 31, thereby improving the assembly efficiency of the computer host 10 provided in this embodiment.

[0112] Please continue to combine Figures 24 to 27 , Figure 24 forFigure 19 A cross-sectional view along the LL direction. Figure 25 for Figure 24 A magnified view of the local structure at point M. Figure 26 for Figure 19 Cross-sectional view along the NN direction. Figure 27 for Figure 26 A magnified view of the partial structure at point O. In some optional embodiments, the fastener 30 includes a first fastening part 301 and a second fastening part 302; the first fastening part 301 extends through the motherboard 31 from the side of the motherboard 31 facing the functional module 32 to the side of the motherboard 31 opposite to the functional module 32 and engages with the motherboard 31; the second fastening part 302 is inserted into the first fastening part 301 and presses against the functional module 32 to detachably connect the functional module 32 and the motherboard 31 together.

[0113] Please combine Figure 28 and Figure 29 , Figure 28 This is a schematic diagram of a fastener provided in an embodiment of this application. Figure 29 This is a schematic diagram of another structure of the fastener provided in an embodiment of this application. For example... Figure 25 and 28 As shown, in one optional embodiment, the first fastening part 301 includes a sleeve part 3011 located at the upper end of the motherboard 31. The sleeve part 3011 is for the second fastening part 302 to be inserted into, and the bottom end of the sleeve part 3011 is formed to press against the first stop part 3012 of the motherboard 31. The first fastening part 301 also includes a through part 3013 connected to the lower end of the sleeve part 3011 and penetrating through the third through hole 312 on the motherboard 31. The bottom of the through part 3013 is connected to a snap-fit ​​post 3014 with a diameter smaller than that of the through part 3013. A plurality of snap-fit ​​plates 3015 are provided on the outer periphery of the snap-fit ​​post 3014, and the bottom end of the snap-fit ​​plate 3015 is connected to the bottom end of the snap-fit ​​post 3014. The top of the snap-fit ​​plate 3015 extends away from the central axis of the snap-fit ​​post 3014. The tops of multiple snap-fit ​​plates 3015 abut against the bottom of the main board 31 to engage with the main board 31. The second fastening part 302 includes a plug-in part 3021 inserted into the sleeve part 3011. The top of the plug-in part 3021 is provided with a second stop part 3022. The second stop part 3022 presses against the top of the functional module 32. An arc-shaped connecting plate 3023 is connected to the side of the second stop part 3022. The end of the connecting plate 3023 is connected to the first stop part 3012 to connect the first fastening part 301 and the second fastening part 302 together to prevent the second fastening part 302 from falling off.

[0114] like Figure 27 and Figure 29As shown, in another alternative embodiment, unlike the structure of the fastener 30 described above, the top end of the sleeve portion 3011 may be provided with a third stop portion 3016, and the functional module 32 is sandwiched between the second stop portion 3022 and the third stop portion 3016.

[0115] It should be noted that the functional module 32 adapted to the fastener 30 of the former can be a functional module 32 with a smaller distance from the motherboard 31, while the functional module 32 adapted to the fastener 30 of the latter can be a functional module 32 with a larger distance from the motherboard 31. In this way, when the distance between the functional module 32 and the motherboard 31 is large, the end of the functional module 32 can be effectively fixed to avoid deformation of the end of the functional module 32, which would affect its own function.

[0116] In this embodiment, since the outer peripheral wall of the sleeve portion 3011 is a circular wall, in order to achieve the snap-fit ​​connection between the first fastening portion 301 and the motherboard 31, a notch 321 needs to be formed on the functional module 32 to cooperate with the sleeve portion 3011 of the first fastening portion 301. In this way, the functional module 32 and the motherboard 31 can be snapped together by the fastener 30 described above.

[0117] It is understood that the aforementioned functional module 32 may include a solid-state disk (SSD) module 322 and a mobile hotspot (Wi-Fi) module 323. Since the distance between the SSD module 322 and the motherboard 31 is greater than the distance between the Wi-Fi module 323 and the motherboard 31, in this embodiment, the SSD module 322 and the motherboard 31 are connected together by the fastener 30 in the latter, and the Wi-Fi module 323 and the motherboard 31 are connected together by the fastener 30 in the former.

[0118] It should be noted that functional module 32 may also include modules that implement other functions. Here, there is no restriction on the specific type of functional module 32.

[0119] When assembling the computer host 10 provided in this embodiment, the front shell 11 and the middle shell 12 are first snapped together to form the first shell 1. Then, the functional module 32 and other components are installed on the motherboard 31. Next, the circuit board assembly 3 is installed on the second shell 2 through the snap-fit ​​connection between the motherboard 31 and the second shell 2. Subsequently, the second shell 2 and the circuit board assembly 3 are inserted together into the middle shell 12 so that the top of the cover 21 is snapped together with the middle shell 12. Finally, the support 22 is snapped together with the middle shell 12 through the support pad 20. Thus, the assembly of the computer host 10 is completed.
