[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0025] Traditional desktop computer architecture features a motherboard as the primary component and a graphics card as a secondary component, with the case serving as the outer shell. The graphics card, memory, CPU, and numerous other components are mounted on the motherboard and then enclosed by the case. This desktop case architecture has been used for two or three decades. However, with the increasing size of high-end graphics cards, especially after the introduction of NVIDIA's 40 series, the motherboard-centric, graphics card-secondary configuration has begun to change. Fitting a large graphics card into a conventional case has become increasingly difficult, leading to ever-growing case volumes. Moreover, this situation completely contradicts another major trend in case development: miniaturization.

[0026] In related technologies, given the limited volume of a basic chassis, an expansion unit (like a "U" shaped frame) is used to increase the chassis's capacity and support more configurations. However, this concept essentially involves forcibly combining two chassis into one, and the ability to increase configurations is still limited. The overall volume after this combination is uncontrolled, generally exceeding 20L. For example, it might support a 4090 graphics card or more 3.5" HDDs. For instance, a basic chassis with a volume of 17L could be expanded to 25L by adding a graphics card structure. This contradicts the mainstream trend of smaller chassis sizes.

[0027] Therefore, this application provides an electronic device that can accommodate a large graphics card while also miniaturizing the chassis. The graphics card is the main component, and its size is used as the basis for chassis design. Space is then left inside the chassis to place a small motherboard.

[0028] like Figures 1 to 3 As shown, this application provides an electronic device 1, comprising: A target housing 11 is provided for accommodating at least one target extension 12, the volume of the target housing 11 being adapted to the size of the target extension 12; Assembly structure 13 is disposed on the target housing 11 and is used to accommodate target functional component 14; The output end 121 of the target extension 12 can extend from the target housing 11 into the assembly structure 13 and connect with the target functional component 14.

[0029] In this embodiment, the target expansion component 12 can be any type of graphics card, such as an NVIDIA RTX 4090 graphics card, and the output terminal 121 of the graphics card has gold fingers. The target functional component 14 can be an ITX host or an adapter card. The graphics card corresponding to the ITX host or adapter card has a PCIe X16 Gen4 slot. The target expansion component 12 has gold fingers that extend from the target housing 11 into the assembly structure 13 that accommodates the ITX host or adapter card, and the gold fingers of the target expansion component 12 are compatible with the slot of the ITX host or adapter card. Thus, the target expansion component 12 can insert its gold fingers into the slot of the target functional component 14 to achieve the connection between the target functional component 14 and the target expansion component 12. When the target functional component 14 is an ITX host, it can also be used independently as a mini UMA host.

[0030] In this embodiment, ITX refers to a motherboard smaller than 200mm*200mm, and an ITX host is a relatively small host, typically with a volume of 5L-15L. An ITX host includes a CPU, memory, and integrated graphics. A mini UMA (Unified Memory Architecture) is a small host without a dedicated graphics card.

[0031] In this embodiment, the volume of the target housing 11 is adapted to the size and dimensions of the target extension 12, so that the size of the target can be designed based on the size of the target extension 12. The target housing 11 is also provided with other structures such as power supply structure and heat dissipation structure.

[0032] In this embodiment, the assembly structure 13 can be a separate structure disposed within the target housing 11, or it can be an accommodating space formed by the target housing 11. The dimensions of the assembly structure 13 are adapted to the dimensions of the target functional component 14. The dimensions of the target functional component 14 can be: length 179mm, width 88mm, and height 22+4mm.

[0033] An electronic device 1 provided in this application includes a target housing 11 and an assembly structure 13. A target extension 12 is disposed within the target housing 11, allowing a large-sized target extension 12 to be housed within the housing. The volume of the target housing 11 is adapted to the size of the target extension 12; that is, the size of the target housing 11 is designed based on the size of the target extension 12. A target functional component 14 is housed within the assembly structure 13, which is also housed within the target housing 11. The output end 121 of the target extension 12 can extend to the assembly structure 13 and connect with the target functional component 14. Therefore, the electronic device 1 provided in this application can simultaneously accommodate both the target extension 12 and the target functional component 14 within the target housing 11, without needing to increase the volume of the structure accommodating the target extension 12 on top of the volume of the structure accommodating the target functional component 14, thus reducing the size of the electronic device 1. Thus, the electronic device 1 provided in this application, while accommodating the large-sized target extension 12, ensures miniaturization. Compared to electronic devices 1 in related technologies, the electronic device 1 provided in this application has a volume reduction of approximately 50%.

[0034] like Figures 1 to 3 As shown in the embodiment of this application, the sidewall of the target housing 11 extends inward to form a groove 111 on the outside of the target housing 11 to form the assembly structure 13. The size of the assembly structure 13 is adapted to the target functional component 14, so that the target functional component 14 can be fully embedded in the groove 111 formed by the target housing 11. An opening 112 is provided at the bottom of the groove 111 for the connecting end of the target extension 12 to extend out.

[0035] In this embodiment, the target housing 11 is a quadrangular prism structure. One sidewall of the quadrangular prism structure extends inward to form a groove 111. The size of the groove 111 is adapted to the target functional component 14. The groove 111 and the sidewall forming the groove 111 are both assembly structure 13. That is, the assembly structure 13 is an integrally formed structure on the target housing 11. The target housing 11 can be made of metal or other materials, as long as it is suitable for production and application.

[0036] In this embodiment, an assembly structure 13 is formed by extending and bending inward on the side wall of the target housing 11 to form a groove 111. The assembly structure 13 has a bottom surface, which is located close to the target extension member 12. An opening 112 is provided on the bottom surface so that the output end 121 of the target extension member 12 can extend from the opening 112 into the assembly structure 13, which facilitates the direct insertion of the target extension member 12 and the target functional member 14, thereby avoiding the problems of signal conversion and bandwidth bottleneck.

[0037] In this embodiment, the sidewall of the target housing 11 extends inward and bends to form a groove-shaped assembly structure 13. The target functional component 14 can be disposed within this assembly structure 13, and the bottom of the assembly structure 13 is also provided with an opening 112, so that the output end 121 of the target extension component 12 inside the target housing 11 can extend from the opening 112 to connect with the target functional component 14 disposed within the assembly structure 13. Thus, the assembly structure 13 can be formed simply by bending the target housing 11, eliminating the need for additional fabrication of the assembly structure 13, saving materials, reducing costs, and reducing the thickness occupied by the additionally fabricated assembly structure 13, thereby further reducing the size of the electronic device 1.

[0038] like Figures 1 to 3 As shown in the embodiments of this application, it also includes: A cover plate 15 is disposed at the opening of the groove 111 to cover the groove 111 so that the target housing 11 has an integrated appearance.

[0039] In this embodiment, an assembly structure 13 is formed by extending and bending the side wall of the target housing 11 inward to form a groove 111. The side of the assembly structure 13 opposite to the bottom surface is a slot. The target functional component 14 is placed into the assembly structure 13 through the slot. The bottom surface of the target functional component 14 is placed on the bottom surface of the assembly structure 13. The size of the slot is adapted to the maximum size of the bottom surface of the target functional component 14 and the top surface opposite to the bottom surface, so that the target functional component 14 can be placed into the assembly structure 13 through the slot.

[0040] In this embodiment, the material, color, and pattern of the cover plate 15 are the same as those of the target housing 11.

[0041] In this embodiment, the cover plate 15 may have a hollow structure to facilitate heat dissipation of the target functional component 14.

[0042] In this embodiment, a cover plate 15 is also provided at the slot of the assembly structure 13. The size of the cover plate 15 is adapted to the size of the slot, and the cover plate 15 is detachably connected to the assembly structure 13. Thus, after the target functional component 14 is placed into the assembly structure 13, the cover plate 15 can be placed on the slot and connected to the assembly structure 13, thereby making the appearance of the housing integrated and making the housing of the electronic device 1 more aesthetically pleasing. After the cover plate 15 is placed on the slot, the entire electronic device 1 appears as a single, complete unit, rather than two chassis forcibly pieced together. In addition, the cover plate 15 can also protect the target functional component 14, preventing damage to the target functional component 14 and preventing dust from entering.

[0043] In this embodiment, the cover plate 15 is fixedly connected to the target housing 11 by magnetic attraction, snap-fit, or screws.

[0044] In this embodiment, the cover plate 15 and the target housing 11 can be magnetically connected. The cover plate 15 has a permanent magnet, and the target housing 11 corresponding to the cover plate 15 has a magnetic object. Thus, when the cover plate 15 approaches the target housing 11, the cover plate 15 and the target housing 11 attract each other, and the cover plate 15 can be adsorbed onto the target housing 11.

[0045] In this embodiment, the cover plate 15 has first threaded holes at its four corners, and the target housing 11 has four second threaded holes at the positions corresponding to the four connecting holes. After the cover plate 15 is placed on the slot, the cover plate 15 and the target housing 11 are fixedly connected by four screws.

[0046] In this embodiment, one side of the cover plate 15 is movably connected to the first sidewall of the assembly structure 13 formed by the target housing 11 near the outer side, and the other side has a buckle. The second sidewall of the assembly structure 13 of the target housing 11 near the outer side, which is opposite to the first sidewall, is provided with a slot that matches the buckle. When the cover plate 15 is rotated to the point where both sides correspond to the slots, the buckle is inserted into the slot to fix the cover plate 15 to the target housing 11.

[0047] In this embodiment, the cover plate 15 is detachably connected to the target housing 11, which facilitates the cover plate 15 to be placed on the slot of the assembly structure 13 and to be removed from the slot of the assembly structure 13, thus making it easier for the target functional component 14 to be placed into and removed from the assembly structure 13.

[0048] In this embodiment, when the cover plate 15 is placed on the slot of the assembly structure 13, a film layer can also be attached to the cover plate 15 to further ensure the integrity and aesthetics of the appearance.

[0049] In this embodiment of the application, the electronic device 1 includes a first operating mode and a second operating mode.

[0050] In the first working mode, the target functional component 14 is a host device, which is connected to the target extension component 12 inside the target housing 11, and the electronic device 1 operates as an independent host with full functionality.

[0051] In the second working mode, the target functional component 14 is a transfer device, which is connected to the target extension component 12 inside the target housing 11, and the electronic device 1 is used as an external device in conjunction with other electronic devices 1.

[0052] In this embodiment, the electronic device 1 includes a first working mode and a second working mode. In the first working mode, the target functional component 14 is a host device, and in the second working mode, the target functional component 14 is a transfer device. Regardless of the working mode, the cover plate 15 will cover the slot of the assembly structure 13, so that the electronic device 1 is a complete whole in appearance, rather than a structure forcibly pieced together from two structures.

[0053] like Figure 2 As shown, in one embodiment of this application, the electronic device 1 is in a first working mode, the target functional component 14 is a host device, and a PCIe graphics card is provided in the target housing 11. After the host device is placed in the assembly structure 13, the gold fingers of the PCIe graphics card are inserted into the interface of the host device, so that the electronic device 1 can be used as an independent device with complete functions, and can perform functions such as document editing, data processing and analysis, and communication.

[0054] like Figure 3 As shown, in another embodiment of this application, the electronic device 1 is in a second working mode, the target functional component 14 is an adapter, and the target housing 11 is provided with a target expansion component 12. After the adapter is placed on the assembly structure 13, the output end 121 of the target expansion component 12 is inserted into the interface of the adapter. The adapter can change the original output end 121 of the target expansion component 12 so that other electronic devices 1 can be connected to the adapter. The connection method can be wired or wireless. The other electronic device 1 can be a laptop computer. It can act as a dedicated graphics card for the laptop computer, working together with the laptop computer to improve the performance of the laptop computer and meet more needs, such as running games or software.

[0055] In this embodiment of the application, in the second working mode, the adapter is an adapter card that is adapted to the size of the assembly structure 13. The adapter card can convert the connection port of the target expansion component 12 into a conversion interface, which is used to connect with the electronic device 1 used in conjunction with it.

[0056] In this embodiment, the connection port of the target expansion component 12 can be a PCIe interface, and the interface of the adapter card can be a Thunderbolt or Oculink interface, or a specially customized TGX interface. PCIe (Peripheral Component Interconnect Express) is a high-speed serial bus interface. Thunderbolt is a high-speed data transmission interface that can combine the transmission of data, video, audio, and power onto a single interface. Thunderbolt interfaces can connect peripherals such as hard drives, RAID arrays, video capture devices, and network interfaces at high speed, and can also transmit high-definition video using the DisplayPort protocol. Each Thunderbolt interface can also provide power to peripherals, thus supporting the connection of multiple devices through a single interface. OcuLink is a high-speed interconnect standard developed by PCI-SIG (Peripheral Component Interconnect Special Interest Group, an international organization responsible for developing and maintaining peripheral component interconnect standards). Its full name is Optical-copper Link, and it is mainly used to solve the interconnection needs of PCIe between short-distance devices. It supports PCIe 3.0, 4.0, and 5.0 protocols, with a single-channel data rate of up to 32 GT / s (PCIe 5.0), and achieves high-speed transmission via copper or fiber optic cables. The TGX interface is a proprietary interface primarily used to connect external graphics card expansion docks. Based on OCuLink technology, the TGX interface provides a transmission rate of up to 64Gbps, equivalent to the full bandwidth of PCIe 4.0 x4.

[0057] In this embodiment, the electronic device 1 is in the second working mode, the target functional component 14 is an adapter, and a PCIe graphics card is provided inside the target housing 11. After the adapter is placed on the assembly structure 13, the gold fingers of the PCIe graphics card are inserted into the interface of the adapter, thereby converting the PCIe interface into a Thunderbolt or Oculink interface, or a specially customized interface. Thus, the electronic device 1 can be an independent graphics card box, and other electronic devices can be connected to the independent graphics card box through the adapter, thereby enabling the electronic device 1 provided in this application to be used in conjunction with other electronic devices.

[0058] like Figure 4 As shown in the embodiments of this application, the electronic device 1 further includes: A power supply unit 16 is disposed inside the target housing 11 and connected to the target extension 12, and is capable of supplying power to the target extension 12.

[0059] In this embodiment, the power supply unit 16 can be a battery.

[0060] In this embodiment, a target extension 12 and a power supply unit 16 are provided inside the target housing 11. The size of the target housing 11 is designed based on the size of the target extension 12. The power supply unit 16 is connected to the target extension 12 to provide sufficient power to the target extension 12.

[0061] In this embodiment of the application, the electronic device 1 further includes: Heat dissipation unit 17 is disposed inside the target housing 11.

[0062] In this embodiment, the heat dissipation unit 17 can be a fan.

[0063] In this embodiment, a target expansion member 12, a power supply unit 16, and a heat dissipation unit 17 are provided inside the target housing 11. The target expansion member 12, the power supply unit 16, and the heat dissipation unit 17 do not interfere with each other inside the target housing 11. The size of the target housing 11 is designed based on the size of the target expansion member 12. The power supply unit 16 is connected to the target expansion member 12 to provide sufficient power to the target expansion member 12. The heat dissipation unit 17 is correspondingly provided to the target expansion member to dissipate heat for the target expansion member 12 and prevent the target expansion member 12 from overheating.

[0064] In this embodiment of the application, the target expansion component 12 is a graphics card.

[0065] In this embodiment, the graphics card is a PCIe (Peripheral Component Interconnect Express) graphics card. PCIe graphics cards provide high data transfer rates and support multiple specifications, from PCIe x1 to PCIe x32, to meet the needs of different devices.

[0066] Secondly, this application also provides a computer system, including a first electronic device 1 and a second electronic device 1; The first electronic device 1 includes: a target housing 11 for accommodating at least one target extension 12, the volume of the target housing 11 being adapted to the size of the target extension 12; Assembly structure 13 is disposed on the target housing 11 and is used to accommodate target functional component 14; The output end 121 of the target extension 12 can extend from the target housing 11 into the assembly structure 13 and be connected to the target functional component 14. The second electronic device 1 and the first electronic device 1 are connected through the target functional component 14.

[0067] This application provides a computer system comprising a first electronic device 1 and a second electronic device 1. The first electronic device 1 includes a target housing 11 and an assembly structure 13. A target expansion member 12 is disposed within the target housing 11, allowing a large-sized target expansion member 12 to be housed within the target housing 11. The volume of the target housing 11 is adapted to the size of the target expansion member 12; that is, the size of the target housing 11 is designed based on the size of the target expansion member 12. A target functional member 14 is housed within the assembly structure 13, which is housed within the target housing 11. Thus, the electronic device 1 provided in this application can simultaneously accommodate both the target expansion member 12 and the target functional member 14 within a volume equal to that of the target housing 11, without needing to add the volume of the structure accommodating the target expansion member 12 to the volume of the structure accommodating the target functional member 14, thereby reducing the size of the electronic device 1.

[0068] The target extension 12 has an output end 121 that extends from the target housing 11 into the assembly structure 13 to connect with the target functional component 14. The target functional component 14 can be a converter that can connect with the second electronic device 1, thereby connecting the first electronic device 1 and the second electronic device 1 through the target functional component 14 to realize information transmission between the first electronic device 1 and the second electronic device 1.
