[0033] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0034] In a specific embodiment, the shell of the computing box provided in the present application is suitable for the storage shell of any type of network hardware equipment; for example, the shell can be used as the shell of an edge computing box, and the interior of the shell is used to store device modules such as the CPU, GPU, memory and storage, and edge computing modules, and the shell is also provided with a communication interface and a peripheral interface; for example, the shell can be used as the shell of a router, and the interior of the shell is used to store device modules such as the CPU, WIFI module, power supply and motherboard, and the shell is also provided with input and output interfaces; for example, the shell can be used as the shell of a set-top box, and the interior of the shell is used to store device modules such as the main chip, memory, tuner and demodulator, and the shell is also provided with an audio and video output interface; for the sake of convenience of explanation, the following is an illustrative explanation using the example of the shell of the computing box being suitable for an edge computing box.

[0035] At present, some shells have a small number of parts and are easy to assemble, but have high manufacturing process requirements and high manufacturing costs; some shells have simple structures and low manufacturing costs, but have a large number of parts and low assembly efficiency; some shells have low manufacturing costs and simple structures, but it is inconvenient to install modules inside; based on the above problems, the present application provides a shell for a computing box to improve the above problems.

[0036] In some embodiments, as Figure 1 As shown, Figure 1 An exploded schematic diagram of the shell of a computing box provided in an embodiment of the present application, wherein the shell 100 includes a first shell 110 and a second shell 120, wherein the first shell 110 includes a top 111 and a first side 112 connected to the top 111; the second shell 120 includes a bottom 121, and a second side 122 and a third side 123 respectively located on both sides of the bottom 121 and opposite to each other; wherein the second side 122 is respectively connected to the top 111 and the first side 112, and the third side 123 is respectively connected to the top 111 and the first side 112.

[0037] The shell 100 is a cubic shell. The cube includes a rectangular parallelepiped and a cube. It specifically includes six faces, namely the top, the bottom and four side faces. Its size and material shell can be determined according to actual needs. The shell 100 can be made of plastic material or metal material, such as copper, iron, aluminum and aluminum alloy, etc.

[0038] The first housing 110 includes a top portion 111 and a first side portion 112 connected to the top portion 111. This means that the first housing 110 includes a top surface and a side surface, and the top surface and the side surface are connected. The first housing 110 is an integrally molded structure, and its manufacturing process is not limited. For example, it can be extruded by a mold or processed by CNC (Computerized Numerical Control) machining. CNC machining refers to computerized numerical control precision machining, such as CNC lathes, CNC milling machines, and CNC boring and milling machines.

[0039] The second housing 120 includes a bottom 121, and second and third side portions 122 and 123 located on opposite sides of the bottom 121. This means that the second housing 120 includes a bottom surface and two side surfaces, with the two side surfaces located on either side of the bottom surface and forming opposing surfaces. The second housing 120 is also an integrally molded structure, and its manufacturing process is also not limited. For example, it can be produced by die extrusion or CNC machining.

[0040] The second side portion 122 is connected to the top 111 and the first side portion 112, respectively. This can be understood as one side surface of the second shell 120 being connected to the top surface and the side surface of the first shell 110, respectively. The specific connection method is not limited. For example, the shell 100 is made of metal, and the second side portion 122 can be welded to the top 111 and the first side portion 112, respectively. For example, the shell 100 is made of metal or plastic, and the top 111 and the first side portion 112 can be provided with a first connecting hole 150, and the second side portion 122 can be provided with a connecting through-hole 160. The connecting member 170 passes through the connecting through-hole 160 and is connected to the first connecting hole 150. The first connecting hole 150 can be a screw hole, the connecting through-hole 160 can be a through-hole, and the connecting member 170 can be a connecting screw. The specific connection positions of the first connection holes 150 and the connection through holes 160 can be determined according to needs. For example, on one side of the end face of the first shell 110 , two first connection holes 150 are set on the top 111 and one first connection hole 150 is set on the first side 112 .

[0041] It should be noted that the first connection holes 150 provided on the top 111 and the first side 112 of the first shell 110 can be directly extruded integrally with the first shell 110 when manufacturing the first shell 110 , or can be added later.

[0042] The third side portion 123 is connected to the top portion 111 and the first side portion 112 respectively. The third side portion 123 and the second side portion 122 are symmetrical in structure and are connected in the same manner as the second side portion 122 , which will not be repeated here.

[0043] The shell 100 of the computing box provided in the present application has a first shell 110 having a top 111 and a first side 112 connected to each other, and a second shell 120 having a bottom 121, and a second side 122 and a third side 123 respectively located on both sides of the bottom and opposite to each other. The first shell 110 and the second shell 120 have a simple structure and can be directly spliced ​​and assembled to form the shell 100 of the computing box. In addition, there are no surfaces connected to each other between the first shell 110 and the second shell 120, and a mold extrusion molding scheme can be adopted, which allows for multiple options in the manufacturing process and reduces manufacturing costs.

[0044] In some embodiments, as Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of the first shell of the computing box provided in an embodiment of the present application. Figure 3 This is a structural diagram of the second shell of the computing box provided in an embodiment of the present application. The first shell 110 and the second shell 120 are both profiles and are extruded as a whole.

[0045] Specifically, the first shell 110 and the second shell 120 can be directly extruded integrally using a profile. A profile refers to a solid straight bar of metal that has been plastically processed and has a certain cross-sectional shape and size. It has a wide variety of specifications. Extrusion is a pressure processing method in which a punch or a punch is used to pressurize a blank placed in a die to cause it to produce plastic flow, thereby obtaining a workpiece with a shape corresponding to the die hole or the concave and convex mold of the mold. The pre-prepared blank is placed in an extrusion cylinder or a die, and pressure is applied to extrude the material from the opening of the container. During extrusion, the material is in a state of unequal three-dimensional compressive stress, and the strain state is axial elongation. The three-dimensional compressive stress state is conducive to improving the plasticity of the material. The deformation of the material during extrusion can be large, and the material can be extruded in one step. The extrusion die is easy to manufacture and simple to replace. For example, the first shell 110 and the second shell 120 are made of aluminum alloy. The first shell 110 and the second shell 120 are extruded integrally using an aluminum alloy extrusion die, which is fast, efficient, and low-cost.

[0046] In some embodiments, as Figure 1 and Figure 4 As shown, Figure 4 This is a structural diagram of the third shell of the computing box provided in an embodiment of the present application. The shell 100 also includes a third shell 130. The third shell 130 is opposite to the first side portion 112 and is connected to the first shell 110 and the second shell 120 respectively.

[0047] Specifically, considering that different types of modules need to be installed inside the housing 100 and different interfaces need to be provided on the housing 100, in order to facilitate the installation of the modules and the connection of the interfaces, the housing 100 is separately provided with a third housing 130. The third housing 130 can be understood as the remaining side surface of the cubic housing. The third housing 130 is opposite the first side 112. After the modules are installed inside the housing 100, the third housing 130 is finally connected to the top 111 of the first housing 110 and the second housing 120, respectively. The connection methods include welding and connection using a connector 170. For example, a screw hole is provided on the top 111, a second connection hole 180 is provided on the second housing 120, and the third housing 130 has a connection through-hole 160. The connector 170 passes through the connection through-hole 160 and is connected to the screw hole and the second connection hole 180, respectively.

[0048] In some embodiments, the third housing 130 is stamped or CNC-molded, and is provided with interface connection holes 131 of various specifications and types.

[0049] Specifically, to increase manufacturing efficiency and reduce costs, the third housing 130 can be stamped or CNC-molded, and directly formed with interface connection holes 131 of various specifications and types, such as communication interfaces, input interfaces, and output interfaces. Stamping refers to a processing method that uses a press and a die to apply external force to plates, strips, tubes, and profiles, causing them to plastically deform or separate, thereby obtaining a stamped part of the desired shape and size.

[0050] In some embodiments, combined Figure 2 and Figure 3 As shown, the top 111 includes a heat dissipation portion 1111 and a limiting portion 1112, the heat dissipation portion 1111 and the limiting portion 1112 are connected, and the limiting portion 1112 protrudes from the first end surface 1115 of the heat dissipation portion 1111 in a first direction, and the first direction is a direction perpendicular to the plane where the second side portion 122 is located.

[0051] Specifically, considering that the second side portion 122 and the third side portion 123 need to be connected to the top portion 111 and the first side portion 112, in order to quickly position and connect, the end surface of the top portion 111 is set to a stepped end surface, and the stepped end surface is used to achieve rapid positioning. At the same time, the second side portion 122 and the third side portion 123 are limited to prevent the second side portion 122 and the third side portion 123 from sliding on the end surface of the first shell 110. The top portion 111 includes a heat dissipation portion 1111 and a limiting portion 1112 connected thereto. 12, the first direction is a direction perpendicular to the plane where the second side portion 122 is located, and the limiting portion 1112 protrudes from the first end surface 1115 of the heat dissipation portion 1111 in the first direction, so that there is a step between the first end surface 1115 of the heat dissipation portion 1111 and the end surface of the limiting portion 1112. The specific step difference value is not limited. For example, the step difference size is the thickness of the second side portion 122. After the second side portion 122 is installed, the outer surface of the second side portion 122 is flush with the end surface of the limiting portion 1112.

[0052] In some embodiments, as Figure 2 As shown, the limiting portion 1112 includes a first limiting portion 1112A and a second limiting portion 1112B located on both sides of the heat dissipation portion 1111. The first limiting portion 1112A, the second limiting portion 1112B and the heat dissipation portion 1111 surround to form a heat dissipation cavity 1113. The heat dissipation cavity 1113 has heat dissipation fins 1114, and the heat dissipation fins 1114 are spaced apart in a direction away from the first side portion 112.

[0053] Specifically, considering that part of the computing box 10 needs to dissipate heat, a heat sink 1114 is provided on the first shell 110. The heat sink 1114 is a device for dissipating heat from heat-prone electronic components in electrical appliances. It can be made of aluminum alloy, brass or bronze in the shape of plates, sheets, multiple sheets, etc. The heat sink 1114 is arranged in the heat dissipation cavity 1113 and is spaced apart in the direction away from the first side portion 112. The heat dissipation cavity 1113 is surrounded by a first limiting portion 1112A, a second limiting portion 1112B and a heat dissipation portion 1111 to form a recessed cavity. The first limiting portion 1112A and the second limiting portion 1112B are located on both sides of the heat dissipation portion 1111. The size and spacing of the heat sink 1114 are not limited. In order to ensure the overall aesthetics of the shell 100, the top surface and end surface of the heat sink 1114 are flush with the outer surface of the first shell 110.

[0054] In some embodiments, as Figure 2 As shown, the top 111 and the first side portion 112 are both provided with a first connection hole 150 , and the first connection hole 150 and the heat sink 1114 are integrally extruded from the first shell 110 .

[0055] Specifically, the first housing 110 is directly formed from a profile using an aluminum alloy extrusion die. The formed first housing 110 has a heat sink 1114 and a first connection hole 150. This die extrusion process is fast, efficient, and low-cost in forming the first housing 110. It should be noted that the integrally extruded first connection hole 150 may be an open connection hole, and its structure does not affect the stability of the connection.

[0056] In some embodiments, as Figure 3 As shown, the second side portion 122 and the third side portion 123 are provided with connecting through holes 160 , and the connecting member 170 passes through the connecting through holes 160 and is connected to the first connecting hole 150 .

[0057] Specifically, with respect to the first connecting hole 150 formed by integral extrusion of the first shell 110, in order to improve the stability of the connection and fixation between the second side portion 122 and the third side portion 123 and the first shell 110, the second side portion 122 and the third side portion 123 are provided with connecting through holes 160 at positions corresponding to the first connecting hole 150. The connecting through holes 160 are through holes, and the connecting member 170 can be used as a screw. The connecting member 170 passes through the connecting through holes 160 and is connected to the first connecting hole 150, so that the second side portion 122 and the third side portion 123 are respectively connected and fixed to the first shell 110.

[0058] In some embodiments, as Figure 3 As shown, fixing portions 1211 are provided on both sides of the bottom 121 , and fixing holes 1212 are provided on the fixing portions.

[0059] Specifically, considering that the computing box 10 may need to be fixed, the bottom 121 of the second shell 120 extends to both sides, and the second side portion 122 and the third side portion 123 protrude respectively to form a fixing portion 1211. The size of the fixing portion 1211 can be determined according to needs. There is a fixing hole 1212 on the fixing portion 1211. The fixing piece passes through the fixing hole 1212 to fix the computing box 10 in the required position. In order to improve the fixing stability, two fixing holes 1212 are respectively set on both sides of the bottom 121, and fixed through four fixing holes 1212.

[0060] In some embodiments, as Figure 3 As shown, second connection holes 180 are provided at the connection positions of the bottom 121 with the second side portion 122 and the third side portion 123 , respectively. The second connection holes 180 are integrally extruded by the second shell 120 .

[0061] Specifically, the second shell 120 can also be directly made of profiles and extruded in one piece using an aluminum alloy extrusion die. The formed second shell 120 has a second connection hole 180. The second connection hole 180 can be on the bottom 121 of the second shell 120, or on the second side 122 and the third side 123 of the second shell 120, or at the intersection of the bottom 121 and the second side 122, and at the intersection of the bottom 121 and the third side 123. The second shell 120 formed by this die extrusion process is fast, efficient, and low-cost. It should be noted that the second connection hole 180 formed by integral extrusion may be an open connection hole, and its structure does not affect the stability of the connection.

[0062] In some embodiments, as Figure 5 As shown, Figure 5 This is a structural schematic diagram of a computing box provided in an embodiment of the present application. The computing box 10 includes a shell 100 and a circuit board 200. The first shell 110 and the second shell 120 surround a receiving cavity 140; the circuit board 200 is located in the receiving cavity 140.

[0063] Specifically, the purpose of the computing box 10 is different, and the functional modules on its internal circuit board 200 are different. The circuit board 200 is fixed in the accommodating cavity 140 surrounded by the first shell 110 and the second shell 120. The specific fixing position and fixing method can be determined according to actual needs. For example, the circuit board 200 can be bonded to the bottom 121 of the second shell 120; for example, the circuit board 200 can also be bonded to the top 111 of the first shell 110; for example, the circuit board 200 can also be fixed to the first shell 110 or the second shell 120 through the connecting member 170.

[0064] In some embodiments, as Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 These are partial structural diagrams of the computing box provided in the embodiments of the present application. The top 111 is located on one side of the accommodating cavity 140 and is connected to the circuit board 200, and the other side opposite to the one side has a plurality of heat sinks 1114 arranged at intervals.

[0065] Specifically, considering that the circuit board 200 has multiple functional modules, the functional modules will generate heat during operation. Since the circuit board 200 is located in the accommodating cavity 140, poor heat dissipation may affect the normal operation of the modules on the circuit board 200. In order to improve the heat dissipation efficiency, the shell 100 can be made of a metal material, such as aluminum alloy, and the circuit board 200 is in contact with the top 111 of the first shell 110. A heat sink 1114 is provided on the other side of the top 111 of the first shell 110 to transfer the heat generated by the modules on the circuit board 200 to the top 111, and from the top 111 to the heat sink 1114. This structural arrangement shortens the distance between the heating device and the heat sink 1114, reduces the heat transfer time, and improves the heat dissipation efficiency. The fixed connection method of the circuit board 200 and the top 111 is not limited. For example, a thermal conductive adhesive can be used for fixed connection.

[0066] In some embodiments, as Figure 7 As shown, the circuit board 200 is provided with connection holes 160 at intervals, and the computing box 10 further includes a connection member 170 , which passes through the connection holes 160 and is connected to the top 111 .

[0067] Specifically, in order to improve the connection strength between the circuit board 200 and the computing box 10, a plurality of connecting through holes 160 can be set on the circuit board 200, and a plurality of third connecting holes 190 are set on the top 111. The number and connection positions of the connecting through holes 160 on the circuit board 200 should correspond to the number and positions of the third connecting holes 190 on the top 111. For example, if 6 third connecting holes 190 are evenly spaced on the top 111, then 6 connecting through holes 160 are also evenly spaced on the circuit board 200. The connecting member 170 passes through the connecting through holes 160 and is fixedly connected to the third connecting holes 190, thereby fixing the circuit board 200 at the top 111 position of the first shell 110.
