Description

Technical Field

[0001] The present application belongs to the technical field of computer peripheral auxiliary equipment, and in particular relates to a portable external graphics card box. Background Art

[0002] Laptops are becoming increasingly lightweight, resulting in smaller sizes and limited internal space. Because the more powerful a computer's internal hardware becomes, the larger it becomes and the corresponding heat dissipation structures required to properly function, limited internal space in laptops also restricts hardware configurations. This is particularly true for laptop graphics cards, which typically come in two types: discrete graphics cards and integrated graphics cards. Integrated graphics cards are integrated onto the computer's motherboard, saving internal space but offering relatively poor performance. Discrete graphics cards offer higher performance than integrated graphics cards, but they have their own GPU, video memory, power supply, and heat dissipation. Discrete graphics cards cannot be integrated onto the computer's motherboard. They are bulky and take up a lot of space, making them difficult to install on lightweight laptops. Therefore, using an external graphics card is currently one solution for adding discrete graphics cards to laptops.

[0003] However, as discrete graphics cards continue to improve in performance and as manufacturers vary in production specifications, graphics card sizes vary. Existing external graphics card enclosures are fixed in size and are not compatible with the installation requirements of graphics cards of varying sizes. Furthermore, currently available portable external graphics card enclosures are limited in size and are simply a box that can hold a graphics card, with limited functionality and limited functionality, making them unsuitable for today's portable users. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide an external graphics card box to solve the installation problems of the portable external graphics card box in the prior art, which has a single function and is not compatible with graphics cards of different specifications.

[0005] To achieve the above purpose, the technical solution adopted by this application is to provide an external graphics card box, including:

[0006] The box body comprises a first shell and a second shell combined with each other;

[0007] A mounting plate for mounting a graphics card, the mounting plate being detachably mounted on the end opening of the first housing; an expansion module being mounted on the mounting plate, the expansion module comprising a plurality of expansion interfaces, the plurality of expansion interfaces being distributed on the mounting plate;

[0008] An adjustment assembly includes a fixed frame, a knob, and racks respectively provided on the first housing and the second housing, wherein the first housing and the second housing respectively have a connecting portion for being sleeved on the fixed frame; the knob is provided on the fixed frame, and a gear is connected to the knob, and the gear is respectively engaged with the racks on the first housing and the second housing, and as the knob rotates, the first housing and the second housing are driven to close or extend with each other.

[0009] The beneficial effects of the external graphics card enclosure provided by this application are as follows: Compared with the prior art, this application redesigns the structure of the external graphics card enclosure by adding an expansion module to the graphics card enclosure, providing the graphics card enclosure with an expansion interface for data connection of external devices, allowing the graphics card enclosure to function as an expansion dock, thereby improving the performance of the graphics card enclosure. The graphics card installed in the graphics card enclosure can be electrically connected to a laptop computer via the expansion interface on the expansion module, effectively improving the compatibility of graphics cards of different specifications with the interfaces on the laptop computer.

[0010] In addition, the box body of the graphics card box of the present application is composed of a first shell and a second shell connected in combination, and an adjustment component is provided between the two to adjust the size of the box body, effectively compatible with the installation requirements of graphics cards of different specifications, thereby improving the adaptability of the graphics card box.

[0011] The combined structure of the box body has been improved. The connecting portion of the first shell is a first frame body, which is sleeved on the fixed frame and extends into the second shell body. The connecting portion of the second shell body is a second frame body, which is symmetrically arranged with the first frame body. The second frame body is sleeved on the fixed frame and extends into the first shell body. The first frame body and the second frame body are provided with corresponding racks. When the user operates the knob to rotate, the gear rotates, synchronously driving the two frames to move relative to each other. The two frames are used to link the two shells to move relative to each other, allowing the first shell body and the second shell body to close or extend relative to each other, thereby adjusting the size of the box body.

[0012] In one embodiment, the knob is provided with a connecting shaft that passes through the fixed frame and is connected to the gear, so that the gear is positioned between the rack on the first frame and the rack on the second frame and meshes with each other. In this way, the rack on the first frame and the rack on the second frame simultaneously mesh with the gear on the knob. When the knob is operated and rotated, the first and second housings are synchronously driven to move relative to each other, thereby quickly adjusting the size of the box body and effectively improving adjustment efficiency.

[0013] In one embodiment, the first frame and the second frame are both provided with correspondingly positioned sunken steps. The first frame and the second frame are assembled together so that the sunken steps on the first frame and the sunken steps on the second frame form a movable recess capable of accommodating the gear, and the racks are respectively provided on the sidewalls of the movable recess. The movable recess formed by the assembly of the first frame and the second frame is used to define the movable trajectory of the two frames in linking the first and second housings, thereby effectively improving the guiding effect.

[0014] In one embodiment, a heat dissipation hole is further provided on the box body, and the heat dissipation hole is arranged to avoid the first frame on the first shell and the second frame on the second shell, so as to avoid the first frame or the second frame located inside the box body from blocking the heat dissipation hole, thereby effectively ensuring the heat dissipation effect.

[0015] The mounting plate's assembly and disassembly structure has been improved. The mounting plate further includes a fixing member for securing the mounting plate to the first housing. The first housing has a fixing portion on its end opening for engagement with the fixing member. Thus, the fixing member on the mounting plate engages with the fixing portion on the first housing, allowing the mounting plate to be removably mounted on the end opening of the first housing.

[0016] In one embodiment, the fixing members are elastic buckles symmetrically arranged on both sides of the mounting plate, and the fixing portions are buckle holes formed on the sidewalls of the first housing. The buckle holes are located near the end openings of the first housing, so that the elastic buckles engage with the buckle holes. This allows the mounting plate to be assembled and disassembled manually without the need for tools, effectively improving the convenience of assembly and disassembly of the mounting plate.

[0017] In one embodiment, the end opening of the first housing further comprises a positioning notch for the elastic buckle to be inserted into, and the buckle hole is disposed adjacent to the positioning notch. Thus, the elastic buckle can be installed along the positioning notch and then engage with the buckle hole, achieving automatic alignment and guidance, thereby effectively improving installation efficiency.

[0018] In another embodiment, the fixing members are connecting ears symmetrically arranged on both sides of the mounting plate, each having a connecting hole. The fixing portion is a mounting hole formed on either side of the end opening of the first housing. The connecting ears are configured to overlap the ends of the first housing, aligning the connecting holes with the mounting holes for attaching fasteners such as screws. This simple structure is easy to implement, allowing the mounting plate to be mounted and fixed to the first housing.

[0019] The box body has been improved with feet installed on its bottom side, and the knob is located on the top side of the box body opposite the bottom side. The feet provide support at the bottom of the box body, allowing the box to stand upright. The knob is located on the top side of the box body, making it easy to operate and adjust the size of the box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this 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.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0043] An external graphics card enclosure is a solution for adding a discrete graphics card to a laptop. By connecting a cable, the laptop can be connected to an external graphics card, thereby improving the laptop's performance. However, as discrete graphics cards improve in performance and as different manufacturers meet varying specifications, graphics card sizes vary. Traditional external graphics card enclosures are fixed in size and are not compatible with graphics cards of varying sizes. Users are forced to purchase a graphics card enclosure that meets the size and connectivity requirements of their graphics card.

[0044] Furthermore, the portable external graphics card enclosures currently available on the market are designed to be easily carried with laptops on the go. Due to their limited size, these enclosures are limited in functionality: they simply house the graphics card and cannot be used for other purposes. Users also need to carry additional expansion devices to accommodate their needs, such as for connecting to additional devices, which increases the burden of carrying. Clearly, current graphics card enclosures no longer meet the portability requirements of today's users.

[0045] Here, the embodiment of the present application provides a new type of external graphics card box that is convenient for users to carry when going out. The structure of the graphics card box is redesigned, which can not only solve the installation problem of traditional graphics card boxes being incompatible with graphics cards of different specifications, but also integrate expansion interface functions. At the same time, it solves the problem of traditional graphics card boxes being single in function and being compatible with the wiring ports on laptops. It is now described in detail.

[0046] Please also refer to Figure 1 and Figure 2 The external graphics card box includes a box body, a mounting plate 3 and an adjustment component.

[0047] The box body comprises a first shell 1 and a second shell 2 that can be assembled together to form a complete box body. In this embodiment, the first shell 1 is open at both ends: one end is open for assembly with the second shell 2, and the other end is open for mounting the mounting plate 3. The second shell 2 is blind at one end and has a port at the other end for assembly with the first shell 1.

[0048] Mounting plate 3 is used to mount a graphics card. It has a mounting hole 31 for the graphics card. The graphics card's baseboard can be fixed to mounting hole 31, allowing the graphics card's data interface to be exposed through mounting hole 31. Mounting plate 3 also has a socket (not shown) for connecting to the graphics card's terminals. This allows the graphics card to be fixed to mounting plate 3 like it would be plugged into a computer motherboard, and then connected to a laptop computer via a cable through the output interface on mounting plate 3.

[0049] Preferably, the mounting port 31 on the mounting plate 3 can adopt the structure of the mounting port 31 on a traditional desktop computer mainframe for mounting a graphics card, so that the graphics card box can be compatible with the installation requirements of high-performance graphics cards used on desktop computers.

[0050] like Figure 2 As shown, the mounting plate 3 is detachably mounted on the end opening of the first housing 1, allowing the graphics card to extend from the interior of the first housing 1 into the second housing 2 and be accommodated within the combined inner cavity of the first and second housings 1, 2. During disassembly, the mounting plate 3 is released from the first housing 1 and removed from the combined inner cavity of the first and second housings 1, 2, along with the graphics card.

[0051] like Figure 1 As shown, an expansion module is provided on the mounting plate 3, and the expansion module includes multiple expansion interfaces 32. The multiple expansion interfaces 32 are distributed on the mounting plate 3, so that the graphics card box also has the function of an expansion dock, and can provide multiple expansion interfaces 32 to facilitate the user's expansion connection needs and effectively improve the performance of the graphics card box.

[0052] These expansion interfaces 32 may preferably be different types of data ports, including but not limited to Type-C, USB, HDMI, etc., to accommodate data connections for various electronic products. Each type of expansion interface 32 may include one or more, and the specific configuration may depend on the surface area of the mounting plate 3, which is not specifically limited herein.

[0053] In actual applications, in order to be compatible with graphics cards of different specifications and the data interface compatibility of laptop computers, the corresponding expansion interface 32 can be selected to be electrically connected to the data interface on the laptop computer, thereby improving the data connection compatibility between the graphics card box and the laptop computer.

[0054] Please also refer to Figure 1 、 Figure 3 and Figure 4 The adjustment assembly includes a fixed frame 4, a knob 5, and racks 6 mounted on the first and second housings 1 and 2, respectively. The first and second housings 1 and 2 each have a connection portion for being sleeved onto the fixed frame 4. The knob 5 is mounted on the fixed frame 4 and connected to a gear 51. The gear 51 meshes with the racks 6 on the first and second housings 1 and 2, respectively. Rotating the knob 5 causes the first and second housings 1 and 2 to close or extend relative to each other. This allows the length of the housing to be adjusted to accommodate the installation requirements of graphics cards of varying specifications.

[0055] Compared to the prior art, the external graphics card enclosure provided in the present embodiment of the present application features a redesigned structure. On one hand, an expansion module is added to the graphics card enclosure, providing the enclosure with an expansion interface 32 for connecting data to external devices, allowing the enclosure to function as an expansion dock and thereby improving its performance. Furthermore, the graphics card installed in the enclosure can also be electrically connected to a laptop computer via the expansion interface 32 on the expansion module, effectively improving the compatibility of graphics cards of varying specifications with the laptop's interface.

[0056] On the other hand, considering that graphics cards of different specifications vary greatly in length, an adjustable design is provided for the length of the graphics card box. The box body of the graphics card box of the present application is composed of a first shell 1 and a second shell 2, which are connected together. An adjustable component is provided between the two to adjust the overall length of the box body. Specifically, the adjustment component includes a fixed frame 4, a knob 5, and a rack 6 respectively provided on the first shell 1 and the second shell 2. The first shell 1 and the second shell 2 are simultaneously connected to the fixed frame 4. The knob 5 is also provided on the fixed frame 4. The knob 5 is connected to the knob 5, and the gear 51 is engaged with the rack 6 on the two shells. The user can operate the knob 5 to drive the gear 51 to rotate, synchronously driving the two shells to move relative to each other, allowing the first shell 1 and the second shell 2 to close together to shorten the length of the box body, or to extend each other to expand the length of the box body, thereby adjusting the size of the box body, effectively compatibility with the installation requirements of graphics cards of different specifications, and thus improving the adaptability of the graphics card box.

[0057] In addition, the engagement of the gear 51 with the rack 6 enables stepless adjustment, allowing the user to arbitrarily adjust the length of the box body according to the size of the graphics card accommodated in the box body, effectively increasing the adjustable range of the adjustment component.

[0058] Regarding the combined structure of the two shells on the box body, in one embodiment of the present application, please refer to Figure 4 、 Figure 5 and Figure 6 The connecting portion on the first housing 1 is a first frame 11, which is sleeved on the fixed frame 4 and extends into the second housing 2. The connecting portion on the second housing 2 is a second frame 21 symmetrically arranged with the first frame 11, which is sleeved on the fixed frame 4 and extends into the first housing 1.

[0059] In this embodiment, if Figure 5 and Figure 6As shown, the first frame 11 and the second frame 21 can preferably be three frames arranged in half, and the two frames are combined to form the inner ring of the box body. The first frame 11 is arranged on the first shell 1, and the second frame 21 is arranged on the second shell 2. When the first shell 1 and the second shell 2 are combined with each other, the first frame 11 and the second frame 21 are both sleeved on the fixed frame 4 and then extended into the corresponding shell, effectively ensuring the mobility of the two frames.

[0060] The first frame 11 and the second frame 21 are each provided with a rack 6, and the racks 6 on the two frames correspond to each other. Specifically, racks 6 can be provided on the edges of the same side of the first frame 11 and the second frame 21, and the racks 6 are respectively engaged with the teeth on the gear 51.

[0061] In this way, when the user operates the knob 5 to rotate, the gear 51 will be driven to rotate to synchronously drive the two frames to move relative to each other, and the two frames will be used to link the two shells to move relative to each other, so that the first shell 1 and the second shell 2 can be closed or extended with each other, thereby facilitating the adjustment of the size of the box body.

[0062] Regarding the structure on the fixed frame 4, in one embodiment of the present application, please refer to Figure 4 、 Figure 7 and Figure 8 A connecting shaft 52 is provided on the knob 5, and a through hole (not shown) is provided on the fixed frame 4 so that the connecting shaft 52 can pass through the fixed frame 4 and connect with the gear 51, so that the gear 51 is located between the rack 6 on the first frame body 11 and the rack 6 on the second frame body 21 and meshes with each other.

[0063] In this way, the rack 6 on the first frame body 11 and the rack 6 on the second frame body 21 are simultaneously engaged with the gear 51 of the knob 5. When the user operates the knob 5 to rotate, the first shell 1 and the second shell 2 can be synchronously driven to move relative to each other, thereby quickly adjusting the size of the box body and effectively improving the adjustment efficiency.

[0064] Regarding the structures on the first frame 11 and the second frame 21, in one embodiment of the present application, please refer to Figure 4 and Figure 9 The first frame body 11 and the second frame body 21 are both provided with corresponding sunken steps 7. The first frame body 11 and the second frame body 21 are assembled with each other so that the sunken steps 7 on the first frame body 11 and the sunken steps 7 on the second frame body 21 form a movable pit that can accommodate the gear 51, and there are racks 6 on the side walls of both sides of the movable pit.

[0065] In this way, the movable recess formed by the first frame 11 and the second frame 21 is utilized to define the movable trajectory of the two frames in linking the first shell 1 and the second shell 2, thereby effectively improving the guiding effect.

[0066] In the examples of this application, please refer to Figure 5 The box body of the graphics card box is also provided with heat dissipation holes 8, preferably a heat dissipation grid composed of multiple heat dissipation holes 8, so that the heat generated by the graphics card loaded in the graphics card box during operation can be discharged to the outside of the box body in time, thereby improving the heat dissipation effect.

[0067] Among them, these heat dissipation holes 8 are arranged to avoid the first frame 11 on the first shell 1 and the second frame 21 on the second shell 2, so as to avoid the first frame 11 or the second frame 21 located inside the box body from blocking the heat dissipation holes 8, thereby effectively ensuring the heat dissipation effect.

[0068] Regarding the disassembly and assembly structure of the mounting plate 3 on the box body, in one embodiment of the present application, please refer to Figure 2 and Figure 10 The mounting plate 3 also includes a fixing piece for fixing the mounting plate 3 on the first housing 1, and the end opening of the first housing 1 has a fixing portion for mounting and cooperating with the fixing piece.

[0069] In this way, the fixing piece on the mounting plate 3 is mounted and matched with the fixing portion on the first housing 1 , so that the mounting plate 3 is detachably arranged on the opening at the end of the first housing 1 .

[0070] In actual use, mounting plate 3 serves as the mounting plate for the graphics card, and the graphics card is installed together with the mounting plate 3. First, the graphics card is inserted into the case through the end opening of the first shell 1 until the mounting plate 3 covers the end opening of the first shell 1. Then, the fixings on the mounting plate 3 engage with the fixings on the first shell 1 to secure the mounting plate 3 to the case, effectively sealing the end opening of the first shell 1 and allowing the graphics card to be accommodated within the case.

[0071] The specific structures of the fixing member on the mounting plate 3 and the fixing portion on the first housing 1 include but are not limited to the following forms:

[0072] In one embodiment of the present application, see Figure 10 The fixing members on the mounting plate 3 may preferably be elastic buckles 33 symmetrically arranged on both sides of the mounting plate 3. The fixing portion on the first housing 1 may preferably be a buckle hole 12 provided on the side wall of the first housing 1. The buckle hole 12 is provided near the end opening of the first housing 1 so that the elastic buckles 33 can be buckled with the buckle hole 12 to fix the mounting plate 3 to the end opening of the first housing 1.

[0073] In this way, the installation plate 3 can be disassembled and assembled by hand without auxiliary tools, which effectively improves the convenience of the disassembly and assembly operation of the installation plate 3.

[0074] In this embodiment, the elastic buckle 33 on the mounting plate 3 includes a connecting plate 331 and a hook portion 332 extending from the end of the connecting plate 331. The connecting plate 331 is vertically attached to the edge of the mounting plate 3, and the hook portion 332 is formed on the end of the connecting plate 331. To complement this, the buckle hole 12 is defined in the side wall of the first housing 1. The buckle hole 12 can be a through hole or a blind hole, as long as it can interlock with the hook portion 332.

[0075] Preferably, if Figure 10 As shown, the outer surface of the connecting plate 331 is further provided with a contact portion 333 for a person's finger to press. In this embodiment, the contact portion 333 can preferably be a groove on the outer surface of the connecting plate 331, so that a person can press the connecting plate 331 to allow the hook portion 332 to be separated from the buttonhole 12 and release the buckle.

[0076] Preferably, in one embodiment of the present application, see Figure 10 The end opening of the first shell 1 also has a positioning notch 13 for the elastic buckle 33 to be embedded in. The positioning notch 13 matches the shape of the elastic buckle 33, and the buckle hole 12 is adjacent to the positioning notch 13.

[0077] In this way, the elastic buckle 33 can be installed in place along the positioning notch 13 and buckled with the buckle hole 12, thereby achieving automatic alignment and guiding effects, effectively improving installation efficiency.

[0078] In another embodiment of the present application (not shown), the fixing member may preferably be connecting ears (not shown) symmetrically arranged on both sides of the mounting plate 3, and the connecting ears have connecting holes.

[0079] The fixing portion can preferably be a mounting hole (not shown) opened on both sides of the end opening of the first shell 1. Specifically, the mounting hole can be a screw hole opened on the side wall of the first shell 1, and the mounting hole is arranged near the end opening of the first shell 1.

[0080] The connecting ears are used to overlap on both sides of the end opening of the first shell 1 so that the connection holes correspond to the mounting holes for installing fasteners such as screws. The structure is simple and easy to implement.

[0081] When the mounting plate 3 is covered on the end opening of the first shell 1, the connecting ears on the mounting plate 3 can be overlapped on the side wall of the first shell 1 so that the connection holes on the connecting ears correspond to the mounting holes on the first shell 1, so that fasteners such as screws can be installed through the connection holes and the mounting holes to achieve a fixed connection.

[0082] For the structure on the box body, in one embodiment of this application, please refer to Figure 1 and Figure 11The box body is further provided with a foot 9, which is arranged on the bottom side of the box body, and the knob 5 is arranged on the top side of the box body opposite to the bottom side.

[0083] Thus, the bottom of the box body is supported by the feet 9 so that the box body can be placed upright. The knob 5 is arranged on the top side of the box body, which is convenient for people to operate the knob 5 and easily adjust the size of the box body.

[0084] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
