Description

Technical Field

[0001] The present invention relates to the technical field of computers, and in particular to a desktop computer case. Background Art

[0002] The desktop computer case is the protective outer shell of a desktop computer, which is used to fix and install core computer components such as the motherboard, power supply, hard disk, optical drive, etc., and also supports and protects the corresponding computer accessories.

[0003] With the development of technology, desktop computers are gradually becoming smaller in design, but for graphics cards with the same nominal performance, large-size graphics cards may have certain advantages due to better heat dissipation design and looser component layout. In addition, large-size graphics cards often mean more space and resources for installing additional components and interfaces, such as auxiliary power supply circuits, more video memory chips, more display output interfaces, etc. These additional components and interfaces can provide better performance and scalability to meet users' higher-level needs.

[0004] Therefore, some users still hope to use a graphics card that is larger than the case in their computers when using a small-sized desktop case. However, there is currently no perfect solution for the use of a small-sized case with a large-sized graphics card. Users can only consider replacing the case or the graphics card to make the two sizes compatible with each other, or placing the graphics card outside the case, which brings additional expenses to users, increasing their monetary costs while also invisibly increasing their time costs. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a desktop computer chassis, which can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A desktop computer case is provided, comprising:

[0008] A chassis body, wherein a receiving cavity for accommodating a graphics card is formed inside the chassis body, and an opening communicating with the receiving cavity is formed on one side of the chassis body, and the opening allows the graphics card to pass through the receiving cavity to the outside of the chassis body;

[0009] The opening on one side of the chassis body allows a graphics card whose length is larger than the chassis body to extend outward, thereby solving the problem of incompatibility between the graphics card and the chassis size.

[0010] A shielding cover is detachably arranged on the chassis body and covers the opening, and an expansion cavity communicating with the receiving cavity is formed in the shielding cover.

[0011] On the basis that the graphics card extends from the opening, the extended part of the graphics card can be protected by a shielding cover. While preventing external electromagnetic waves from interfering with the graphics card, the shielding cover can also effectively prevent the extended part of the graphics card from directly colliding with external objects, reducing potential damage to the graphics card caused by accidents, enhancing the stability between the graphics card and the chassis main body, and helping to extend the service life of the graphics card and the desktop computer.

[0012] As an alternative implementation, the chassis main body and the shielding cover are detachably connected through a disassembly and assembly structure, and the disassembly and assembly structure includes:

[0013] A first disassembly and assembly component, provided on the chassis main body;

[0014] A second disassembly and assembly component, provided on the shielding cover, and the first disassembly and assembly component and the second disassembly and assembly component are detachably connected.

[0015] Reduce the disassembly and assembly difficulty of the shielding cover on the chassis main body, and reduce the operating space occupied during the disassembly and assembly of the shielding cover, making the design of the shielding cover on the chassis main body more suitable for the miniaturized desktop computer chassis.

[0016] As an alternative implementation, the first disassembly and assembly component includes a plurality of first clamping portions, and the plurality of first clamping portions are arranged at intervals along the edge of the opening. The second disassembly and assembly component includes a plurality of second clamping portions, and the plurality of second clamping portions are arranged at intervals along the cover edge of the shielding cover;

[0017] One of the first clamping portion and the second clamping portion is set as a clamping interface, and the other of the first clamping portion and the second clamping portion is set as a clamping member that can be clamped into or disengaged from the clamping interface along the disassembly and assembly direction.

[0018] Through the above settings, the assembly range of the shielding cover on the chassis main body can be effectively expanded, thereby improving the assembly strength between the shielding cover and the chassis main body.

[0019] As an alternative implementation, when the first clamping portion is set as the clamping interface, a limiting member protruding in the direction away from the receiving cavity is provided at the position of the first clamping portion on the chassis main body. A hollow clamping cavity is formed inside the limiting member, and the clamping cavity is used to receive at least part of the clamping member;

[0020] The clamping interface is opened at one end of the limiting member so that the clamping cavity is communicated with the outside of the chassis main body.

[0021] After defining the disassembly and assembly directions of the first disassembly and assembly component and the second disassembly and assembly component, by protruding a limiting member on the chassis main body, the first clamping portion provided on the limiting member and the second clamping portion of the shielding cover can be made to coincide in path during the assembly process, enabling the shielding cover to be correctly installed on the chassis main body and making its disassembly and assembly process simpler.

[0022] As an alternative implementation, a process hole communicating with the receiving cavity and the clamping cavity is further formed on the chassis main body, and a constraining member is provided on the side of the limiting member facing away from the process hole;

[0023] A pressing protrusion protrudes from the side of the constraining member facing the process hole; or

[0024] In a state where the clamping member is located in the clamping cavity, a pressing protrusion protrudes from the side of the clamping member facing the constraining member.

[0025] Forming a process hole at the position of the chassis main body corresponding to the first disassembly and assembly component can make the setting of the first disassembly and assembly component on the chassis main body meet the requirements of sheet metal processing. Moreover, when the pressing protrusion applies a corresponding pressure to the second disassembly and assembly component, the process hole can also provide a certain plastic deformation space for it, ensuring the stable assembly of the first disassembly and assembly component and the second disassembly and assembly component.

[0026] As an alternative implementation, in the disassembly and assembly direction of the chassis main body and the shielding cover, at least two spaced-apart first clamping portions are provided at the first end of the opening on the chassis main body, and at least one first clamping portion is provided on each of the opposite sides of the opening on the chassis main body in a direction parallel to the plane of the opening and perpendicular to the disassembly and assembly direction of the chassis main body and the shielding cover;

[0027] The positions of the second clamping portions respectively correspond to the positions of the first clamping portions.

[0028] By further defining the positions of the first clamping portions, it can be ensured that the shielding cover can be installed on the chassis main body more stably.

[0029] As an alternative implementation, a limiting component is further provided at the second end of the opening on the chassis main body;

[0030] In a state where the shielding cover is disposed on the chassis main body, the limiting component is located at one end of the shielding cover and is used to limit the shielding cover from detaching from the chassis main body.

[0031] The limiting component can impose a constraint on the shielding cover assembled on the chassis main body, preventing the shielding cover from easily detaching from the chassis main body along the disassembly direction.

[0032] As an alternative embodiment, the limiting assembly includes a plurality of limiting protrusions, and each of the limiting protrusions protrudes from the surface of the chassis main body in a direction away from the receiving cavity; and

[0033] The plurality of limiting protrusions are arranged at intervals along the edge of the second end of the opening.

[0034] In this way, it is ensured that the overall shielding cover can be stably restricted on the chassis main body.

[0035] As an alternative embodiment, the shielding cover includes:

[0036] A baffle; and

[0037] A support plate, the support plate is arranged around the edge of the baffle, the support plate is arranged at an angle with the baffle, and the baffle and the support plate enclose to form the expansion cavity;

[0038] A folding plate is arranged on the side of the support plate away from the baffle and extends in a direction away from the expansion cavity.

[0039] As an alternative embodiment, a plurality of heat dissipation holes communicating with the expansion cavity are uniformly arranged on the side of the shielding cover away from the chassis main body.

[0040] The beneficial effects of the present invention are as follows: By opening an opening communicating with the receiving cavity on one side of the chassis main body, the overlong graphics card can pass through the opening and extend out of the chassis main body when installed in the receiving cavity, thereby solving the problem of incompatibility between the size of the graphics card and the chassis, ensuring that the graphics card and the chassis main body can be normally installed and used, enabling the desktop computer chassis to provide higher graphics card compatibility, broadening the user's choice range of graphics cards, avoiding the additional cost of having to reselect the chassis or graphics card, and improving the assembly efficiency of the desktop computer.

[0041] By providing a shielding cover on the chassis main body, even if the graphics card extends out of the chassis main body, it can still be protected by the shielding cover, thereby effectively blocking the leakage of electromagnetic waves from the inside of the chassis main body to the outside and preventing the interference of external electromagnetic waves to the graphics card, making the computer system more stable and reliable. In addition, the shielding cover also serves as a physical barrier between the graphics card and the external environment of the chassis main body, which can effectively prevent the part of the graphics card extending out of the opening from directly colliding with external objects, reduce the potential damage to the graphics card caused by accidental situations, enhance the stability between the graphics card and the chassis main body, and contribute to extending the service life of the graphics card and the desktop computer.

Detailed implementation manner

[0057] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on the top" of the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under the bottom" of the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature has a lower horizontal height than the second feature.

[0060] Currently, desktop computers are tending towards miniaturized design, which makes computers more portable, saves space, and adapts to the needs of modern home and office environments. However, for graphics cards, for graphics cards with the same nominal performance, it is obvious that large-size graphics cards still have certain advantages in performance compared to small-size graphics cards (large-size graphics cards may show certain advantages due to better heat dissipation design and looser component layout, etc., and large-size graphics cards often mean more space and resources for installing additional components and interfaces, such as auxiliary power supply circuits, more video memory particles, more display output interfaces, etc. These additional components and interfaces can provide better performance and scalability to meet users' higher-level needs), so many users hope to use large-size graphics cards in small-size chassis.

[0061] However, there is still no perfect solution for the use of small-sized chassis with large-sized graphics cards. The internal space of a small-sized chassis is limited and it is difficult to accommodate a large-sized graphics card. Even if the graphics card can be barely placed in the chassis, it may cause problems such as poor heat dissipation and wiring difficulties due to insufficient space. In addition, high-performance graphics cards generate a lot of heat when working, and an effective heat dissipation system is required to maintain its stable operation. However, the heat dissipation space of a small-sized chassis is limited and may not provide sufficient heat dissipation, resulting in overheating, performance degradation, or even damage to the graphics card. This not only fails to meet the needs of users with high requirements for graphics card performance, but also increases the assembly difficulty for users who are in the process of assembling a desktop computer. Users can only consider replacing the chassis or graphics card to make the sizes of the two compatible with each other, or placing the graphics card outside the chassis, which brings additional expenses to users, increasing the user's monetary cost while also invisibly increasing the user's time cost.

[0062] In view of this, the present embodiment provides a desktop computer case, which solves the technical problem that a small-sized case is difficult to adapt to the installation of a large-sized graphics card by providing an opening on one side of the case body for the graphics card to pass through, and then providing a shielding cover on the case body at the position of the opening.

[0063] Please refer to the instruction manual Figure 1 - Figure 2 , Figure 5, As the carrier and protective case of desktop computer hardware, the design structure of the desktop computer case has a crucial impact on the performance, heat dissipation, compatibility, and maintainability of the desktop computer. The desktop computer case includes a case main body 10, which is the main structural part of the desktop computer case and is usually made of metal materials (such as steel or aluminum alloy) to ensure sufficient strength and durability, enabling the case main body 10 to effectively protect the internal hardware from physical damage, such as collisions, static electricity, dust, etc. A hollow receiving cavity 11 is formed inside the case main body 10, and the receiving cavity 11 is used to provide a corresponding installation space for the hardware of the desktop computer (such as the motherboard, graphics card 30, power supply, etc.), while the cavity wall of the receiving cavity 11 is used to provide the installation positions for the relevant hardware.

[0064] Generally, the case of a desktop computer is roughly in a cuboid structure, and the structure of the receiving cavity 11 is determined according to the structure of the case main body 10. There are no strict limitations and requirements for this embodiment, but for a more comprehensive understanding of this solution, this embodiment takes the case where the case main body 10 is roughly in a cuboid structure as an example.

[0065] As Figure 1 , Figure 5 shown in the figure, in this embodiment, the case main body 10 has a front panel 16 and a rear panel 17 on the opposite sides in its length direction respectively. The front panel 16 and the rear panel 17 are connected by other panels or covers on the upper and lower sides and the left and right sides, so that the front panel 16, the rear panel 17, and the other panels or covers enclose and define the above-mentioned receiving cavity 11. The front panel 16, the rear panel 17, and the other panels or covers can be set as an integral part, or can be used as independent components and cooperate with each other through subsequent relevant assembly processes (such as welding, bonding, snap connection, plug connection, etc.).

[0066] An opening 12 communicating with the receiving cavity 11 is formed on one side of the chassis main body 10. On the basis of the above embodiment, the opening 12 is formed on the rear panel 17 of the chassis main body 10. The opening 12 allows the graphics card 30 to pass through the chassis main body 10 from the receiving cavity 11. In the actual application scenario of a desktop computer, if the length dimension of the graphics card 30 used in the computer is greater than the length dimension of the chassis main body 10, the graphics card 30 can be arranged along the length direction of the receiving cavity 11 (the direction from the front panel 16 to the rear panel 17), and then pass through the opening 12 on the rear panel 17 to extend out of the chassis main body 10 (the rear panel 17), so as to avoid the interference of the chassis main body 10 on the graphics card 30. The main purpose of this design is to solve the problem of incompatibility between the graphics card 30 and the chassis in terms of size (usually the length dimension), so that a large-size graphics card 30 can be applied inside a small-size chassis main body 10. While meeting the usage requirements of users with certain requirements for the performance of the graphics card 30, most of the structure of the graphics card 30 still remains in the receiving cavity 11, so that the chassis main body 10 can still provide certain protection and stability for the graphics card 30, and to a certain extent ensure the performance of the desktop computer.

[0067] From the above content, it can be seen that although the method of forming the opening 12 on the chassis main body 10 can make it adapt to a graphics card 30 with a length dimension greater than the size of its internal receiving cavity 11, correspondingly, due to the relationship that the opening 12 is processed on the chassis main body 10 (the rear panel 17) by a material-removing processing method, the strength and protection ability of the chassis main body 10 may be reduced accordingly. At the same time, in the actual application scenario of a desktop computer, due to the relationship that part of the graphics card 30 is exposed outside the chassis main body 10, the heat dissipation performance of the part of the graphics card 30 outside the chassis main body 10 will be affected to a certain extent, and there is also a risk of collision and interference with external objects, thus shortening the service life of the graphics card 30 and even the desktop computer.

[0068] Therefore, please continue to refer to the attached Figure 1 - Figure 4 The desktop computer chassis further includes a shielding cover 20. The shielding cover 20 is detachably arranged on the chassis main body 10 and covers the opening 12. In the actual application scenario of a desktop computer, an expansion cavity 21 communicating with the receiving cavity 11 through the opening 12 is formed inside the shielding cover 20. The expansion cavity 21 extends in a direction away from the opening 12. In this way, in the actual application scenario of a desktop computer, the part of the graphics card 30 extending out from the opening 12 is located in the expansion cavity 21. Therefore, the dimension of the expansion cavity 21 extending in the direction away from the opening 12 also needs to be determined according to the difference in the length dimensions between the graphics card 30 and the chassis main body 10, so as to ensure that the part of the graphics card 30 extending out of the chassis main body 10 can be completely covered by the shielding cover 20.

[0069] It can be understood that the shielding cover 20 of this embodiment is generally made of a metal material, so that it can at least provide the following functions:

[0070] First, to prevent electromagnetic interference, the shielding cover 20 made of a metal material (or conductive material) can effectively block the leakage of electromagnetic waves from the inside of the receiving cavity 11 to the outside of the chassis main body 10. At the same time, it can also prevent the electromagnetic waves outside the chassis main body 10 from interfering with the part of the graphics card 30 extending through the opening 12, ensuring that the graphics card 30 works in a stable environment and avoiding performance degradation or failure of the graphics card 30 due to electromagnetic interference.

[0071] Second, to protect the graphics card 30 from collision. In addition to being able to isolate interference, the shielding cover 20 can also serve as a physical barrier between the extending part of the graphics card 30 and the external environment, effectively preventing the extending part of the graphics card 30 from directly colliding with external objects (such as the desktop, other hardware, or connecting wires, etc.), and extending the service life of the graphics card 30.

[0072] It is worth mentioning that in some embodiments, by covering the extending part of the graphics card 30 with the shielding cover 20, the shielding cover 20 can also provide a certain supporting and fixing effect for the extending part of the graphics card 30, thereby enhancing the stability between the graphics card 30 and the chassis main body 10 and helping to prevent the graphics card 30 from being damaged due to shaking or vibration.

[0073] By setting the shielding cover 20 and the chassis main body 10 in a detachable assembly relationship, the installation and disassembly of the shielding cover 20 (and even the graphics card 30) become more convenient. In this way, when the graphics card 30 or the shielding cover 20 needs to be cleaned, repaired, or replaced, the detachable design makes these operations easier. The user can directly remove the shielding cover 20 to perform necessary maintenance on the graphics card 30 or the inside of the chassis. In addition, the detachable shielding cover 20 also allows the user to replace different sizes or types of shielding covers 20 according to actual needs, so that when installing different model sizes of graphics cards 30 on the chassis main body 10, the shielding cover 20 will not interfere with the graphics card 30 due to its inability to be disassembled and replaced from the chassis main body, eliminating the need to replace the entire chassis main body 10, increasing the compatibility and flexibility of the chassis main body 10, and also helping to reduce the maintenance and replacement costs.

[0074] It should be noted that the detachable assembly method between the shielding cover 20 and the chassis main body 10 in this embodiment is not strictly limited or required for the time being. It can but is not limited to adopting relatively common assembly methods in the current machining field, such as screw fixation (fixing the shielding cover 20 on the chassis main body 10 through screws), snap connection (fixing the shielding cover 20 on the chassis main body 10 using snaps), magnetic attraction connection (adsorbing and fixing the shielding cover 20 on the chassis main body 10 using magnetic components), pin connection (designing corresponding jacks and pins on the chassis main body 10 and the shielding cover 20 so that the shielding cover 20 can be fixed on the chassis by inserting the pin into the jack), and hinge connection (connecting the shielding cover 20 and the chassis main body 10 through a hinge, allowing the user to conveniently flip or rotate the shielding cover 20 to open and close the opening 12 of the shielding cover 20).

[0075] In summary, by opening an opening 12 communicating with the receiving cavity 11 on one side of the chassis main body 10 of this desktop computer chassis, the overlong graphics card 30 can pass through the opening 12 and extend out of the chassis main body 10 when installed in the receiving cavity 11, thus solving the problem of incompatibility between the graphics card 30 and the chassis size, ensuring that the graphics card 30 and the chassis main body 10 can be normally installed and used, enabling this desktop computer chassis to provide higher compatibility for the graphics card 30, broadening the user's selection range for the graphics card 30, and also avoiding the additional cost of having to reselect the chassis or the graphics card 30, and improving the assembly efficiency of the desktop computer.

[0076] By providing a shielding cover 20 on the chassis main body 10, the graphics card 30 can still be protected by the shielding cover 20 even when it extends out of the chassis main body 10, effectively blocking the leakage of electromagnetic waves from the inside of the chassis main body 10 to the outside and preventing external electromagnetic waves from interfering with the graphics card 30, making the computer system more stable and reliable. Moreover, the shielding cover 20 also serves as a physical barrier between the graphics card 30 and the external environment of the chassis main body 10, effectively preventing the part of the graphics card 30 extending out from the opening 12 from directly colliding with external objects, reducing potential damage to the graphics card 30 caused by accidental situations, enhancing the stability between the graphics card 30 and the chassis main body 10, and helping to extend the service life of the graphics card 30 and the desktop computer.

[0077] Please refer to the attached instruction manual Figure 3 - Figure 13, for a more comprehensive understanding of this solution, as a specific implementation of the chassis main body 10 and the shielding cover 20, the chassis main body 10 and the shielding cover 20 are detachably connected through a disassembly and assembly structure. From the above content, it can be understood that the disassembly and assembly structure can, but is not limited to, adopting some of the detachable connection structures exemplified above. Among them, the disassembly and assembly structure includes a first disassembly and assembly component 13 and a second disassembly and assembly component 22. The first disassembly and assembly component 13 is arranged on the chassis main body 10, and the first disassembly and assembly component 13 is used to cooperate with the second disassembly and assembly component 22 to achieve the connection and disassembly of the two. Its structural form can be set according to the actual disassembly and assembly requirements between the chassis main body 10 and the shielding cover 20, such as structural forms like threaded holes, buckles, slide rails, rotating shafts, etc. The second disassembly and assembly component 22 is arranged on the shielding cover 20. As mentioned above, the first disassembly and assembly component 13 and the second disassembly and assembly component 22 are configured to be detachably connected. Therefore, the structural form of the second disassembly and assembly component 22 needs to match the first disassembly and assembly component 13 (structural forms such as screws, buckle protrusions, chutes, rotating seats corresponding to the first disassembly and assembly component 13) to jointly achieve the installation and disassembly of the chassis main body 10 and the shielding cover 20.

[0078] On this basis, the disassembly and assembly direction of the first disassembly and assembly component 13 and the second disassembly and assembly component 22 is parallel to the plane where the opening 12 is located. First, it needs to be explained that the plane where the opening 12 is located refers to the surface of the chassis main body 10 where the opening 12 is opened. For example, in the above embodiment where the opening 12 is opened on the rear panel 17 of the chassis main body 10, the surface of the rear panel 17 is the plane where the opening 12 is located. That is to say, the disassembly and assembly direction of the first disassembly and assembly component 13 and the second disassembly and assembly component 22 is parallel to the surface of the rear panel 17.

[0079] Through the above-mentioned setting method, when the shielding cover 20 is disassembled relative to the chassis main body 10, it is not necessary to move too much in the direction away from the chassis main body 10 (the direction perpendicular to the plane where the opening 12 is located). Thus, to a certain extent, the space reserved during the disassembly and assembly of the shielding cover 20 on the chassis main body 10 is reduced. The shielding cover 20 mainly moves along the direction parallel to the plane where the opening 12 of the chassis main body 10 is located. Especially in the design of a compact chassis main body 10, this parallel disassembly and assembly method can make more effective use of space, reduce interference to the surrounding environment during disassembly and assembly, and is also convenient for users to operate. During the assembly process, the shielding cover 20 needs to allow the extended part of the graphics card 30 to enter the interior of the expansion cavity 21 through the cavity opening of the expansion cavity 21, and make the shielding cover 20 abut against the surface where the opening 12 of the chassis main body 10 is located. Then, by moving along the direction parallel to the surface where the opening 12 is located, the first disassembly and assembly component 13 and the second disassembly and assembly component 22 are mutually coordinated, and the installation of the shielding cover 20 on the chassis main body 10 can be achieved. On the contrary, during the disassembly process, the shielding cover 20 only needs to move a certain distance along the direction parallel to the plane where the opening 12 is located, so that the first disassembly and assembly component 13 and the second disassembly and assembly component 22 are separated from each other, and move in the direction away from the chassis main body 10, so that the expansion cavity 21 is separated from the extended part of the graphics card 30.

[0080] It can also be understood from the above content that during the disassembly and assembly process of the first disassembly and assembly component 13 and the second disassembly and assembly component 22, it is not necessary to rely on tools to achieve their mutual cooperation or separation, which also effectively improves the convenience of users during the disassembly and assembly operation of the shielding cover 20.

[0081] Please continue to refer to the appendix Figure 3 - Figure 13 To improve the assembly stability of the shielding cover 20 on the chassis main body 10, the first disassembly and assembly component 13 includes a plurality of first clamping portions 131, and the plurality of first clamping portions 131 are arranged at intervals along the edge of the opening 12. The second disassembly and assembly component 22 includes a plurality of second clamping portions 221, and the plurality of second clamping portions 221 are arranged at intervals along the edge of the shielding cover 20. Generally, the number of the second clamping portions 221 is set to be the same as the number of the first clamping portions 131, and the positions of the respective second clamping portions 221 on the shielding cover 20 respectively correspond one-to-one to the first clamping portions 131 on the chassis main body 10 to ensure that the respective second clamping portions 221 can be respectively clamped and cooperated with the respective first clamping portions 131. Of course, this embodiment does not make strict limitations and requirements on this. In fact, the number of the first clamping portions 131 and the second clamping portions 221 can be different. By setting more first clamping portions 131 on the chassis main body 10, or setting more second clamping portions 221 on the shielding cover 20, the adaptability of the chassis main body 10 or the shielding cover 20 to different types of shielding covers 20 or chassis main bodies 10 can be effectively improved, thereby improving the versatility of the chassis main body 10 and / or the shielding cover 20.

[0082] When the shielding cover 20 is assembled to the chassis main body 10, the two are respectively cooperated through a plurality of first clamping portions 131 and a plurality of second clamping portions 221 to increase the clamping area between the edge of the shielding cover 20 and the chassis main body 10, ensuring that each part of the edge of the shielding cover 20 can stably cooperate with the chassis main body 10.

[0083] In addition, arranging the plurality of first clamping portions 131 along the edge of the opening 12 is also beneficial to saving the space area occupied by the shielding cover 20 on the chassis main body 10, ensuring that the assembly structure of the shielding cover 20 and the chassis main body 10 is compact and stable.

[0084] Furthermore, one of the first clamping portion 131 and the second clamping portion 221 is set as a clamping opening, and the other of the first clamping portion 131 and the second clamping portion 221 is set as a clamping member that can be clamped or disengaged from the clamping opening along the disassembly and assembly direction. That is to say, in the corresponding first clamping portion 131 and second clamping portion 221 that are matched, when the first clamping portion 131 is set as the clamping opening, the corresponding second clamping portion 221 is set as the clamping member, and when the first clamping portion 131 is set as the clamping member, the corresponding second clamping portion 221 is set as the clamping opening. Of course, in some embodiments, among the plurality of first clamping portions 131 included in the first disassembly and assembly component 13, a part of the first clamping portions 131 can be set as the clamping opening, and another part of the first clamping portions 131 can be set as the clamping member. This embodiment does not make too many limitations on this for the time being, as long as the corresponding second clamping portion 221 is set as the corresponding clamping member or clamping opening to ensure that the shielding cover 20 can be successfully installed on the chassis main body 10.

[0085] In one embodiment, both the chassis main body 10 and the shielding cover 20 are set as sheet metal parts processed by sheet metal technology. On this basis, the clamping opening and the clamping member can be formed together during the processing of the chassis main body 10 and the shielding cover 20, thereby improving the processing efficiency of the first disassembly and assembly component 13 and the second disassembly and assembly component 22 on the chassis main body 10 and the shielding cover 20 respectively, and reducing the process difficulty of the two.

[0086] It can be learned from the prior art that sheet metal technology is a manufacturing process that processes metal sheets into required shapes and sizes through processes such as stamping, bending, stretching, and welding. And setting the clamping opening and the clamping member as sheet metal parts respectively can not only improve the production efficiency of the product, but also greatly reduce the material cost of the product. The first disassembly and assembly component 13 and the second disassembly and assembly component 22 can directly utilize the original structures on the chassis main body 10 and the shielding cover 20 to directly form the clamping opening or the clamping member through corresponding processes. Moreover, sheet metal technology also allows various shapes and sizes of clamping openings and clamping members to be processed on the chassis main body 10 and the shielding cover 20 according to actual needs, so as to meet different appearance modeling requirements and effectively improve the flexibility of the product.

[0087] Please refer to the attached drawings of the specification Figure 3 - Figure 13 , taking the case where the first clamping part 131 is set as the clamping interface as an example. In this embodiment, a limiting part 132 protruding in the direction away from the receiving cavity 11 is provided at the position of the first clamping part 131 on the chassis main body 10. A hollow clamping cavity 133 is formed inside the limiting part 132. The clamping cavity 133 is used to receive at least part of the clamping piece. In the disassembly and assembly direction of the first clamping part 131 and the second clamping part 221, the clamping interface is opened at one end of the limiting part 132, so that the clamping cavity 133 is communicated with the outside of the chassis main body 10. During the assembly process of the shielding cover 20 and the chassis main body 10, the shielding cover 20 moves relative to the chassis main body 10 on the plane where the opening 12 is located along the assembly direction (such as the "assembly direction" indicated by the arrow in the attached Figure 8 - Figure 9 drawing). The clamping piece enters the clamping cavity 133 inside the limiting part 132 through the clamping interface opened at one end of the limiting part 132 during this process, and a certain frictional force is formed between the two by contacting the limiting part 132, so as to realize the assembly of the shielding cover 20 on the chassis main body 10. On the contrary, during the disassembly process of the shielding cover 20 and the chassis main body 10, the shielding cover 20 moves relative to the chassis main body 10 on the plane where the opening 12 is located along the disassembly direction (such as the "disassembly direction" indicated by the arrow in the attached Figure 8 - Figure 9 drawing). The clamping piece gradually disengages from the clamping cavity 133 inside the limiting part 132 through the clamping interface opened at one end of the limiting part 132 during this process until the clamping piece completely disengages from the limiting part 132 at the clamping interface, realizing the disassembly of the shielding cover 20 on the chassis main body 10.

[0088] It can also be understood from the above content that the disassembly and assembly direction of the shielding cover 20 and the chassis main body 10 is basically parallel to the plane where the opening 12 is located, and in some embodiments, the first disassembly and assembly component 13 and the second disassembly and assembly component 22 can be set as sheet metal structures integrally formed with the chassis main body 10 and the shielding cover 20 respectively. Therefore, in order to ensure that the first disassembly and assembly component 13 and the second disassembly and assembly component 22 can cooperate with each other, a limiting part 132 is convexly provided on the surface of the chassis main body 10 in this embodiment, so that the clamping interface and the clamping piece can be on the same surface to realize the final assembly.

[0089] Of course, in other embodiments, this embodiment is not limited to setting the clamping piece as the second clamping part 221 to protrude towards the chassis body so that it can be snapped into the chassis body through the clamping interface.

[0090] Based on the above embodiment, please continue to refer to the attached Figure 3 - Figure 13 , a process hole 14 communicating the receiving cavity 11 and the clamping cavity 133 is further opened on the chassis main body 10. The process hole 14 can save the processing materials of the chassis main body 10 to a certain extent, so as to control the processing cost of the chassis main body 10.

[0091] In the above implementation manner where the first disassembly and assembly component 13 and the second disassembly and assembly component 22 are integrally formed with the chassis main body 10 and the shielding cover 20 respectively through sheet metal processing, the process hole 14 is actually formed during the processing and forming of the limiting member 132. By cutting out a part on the chassis main body 10 that matches the shape of the limiting member 132 and stamping this part in a direction away from the receiving cavity 11, the process hole 14 is formed at the corresponding position while forming the limiting member 132. Therefore, the formation of the process hole 14 is also suitable for the process characteristics of sheet metal processing to a certain extent.

[0092] In some implementation manners, the process hole 14 can also provide at least part of the space for the clamping member to extend into the interior of the chassis main body 10, so as to improve the assembly compactness between the shielding cover 20 and the chassis main body 10.

[0093] A restraint member 1321 is further provided on the side of the limiting member 132 away from the process hole 14. One end of the restraint member 1321 cooperates with the surface where the opening 12 of the chassis main body 10 is located to form a clamping interface, so that when the clamping member is inserted into the clamping cavity 133 through the clamping interface, a frictional force is generated when it contacts the clamping member.

[0094] In one embodiment, at least one side of the restraint member 1321 is further connected to the chassis main body 10 through a connecting member 1322, thereby improving the structural strength of the limiting member 132 on the chassis main body 10, and further being able to constrain the size of the clamping cavity 133 and further guide the movement direction of the clamping member during the disassembly and assembly process.

[0095] In order to appropriately reduce the frictional force between the limiting member 132 and the clamping member on the basis of improving the assembly strength between them, so as to facilitate the disassembly and assembly of the first clamping portion 131 and the second clamping portion 221, a pressing protrusion 222 protrudes from the side of the restraint member 1321 facing the process hole 14, or, in the state where the clamping member is located in the clamping cavity 133, a pressing protrusion 222 protrudes from the side of the clamping member facing the restraint member 1321. Providing the pressing protrusion 222 on one of the limiting member 132 (restraint member 1321) and the clamping member can enable the limiting member 132 and the clamping member to play a role of mutual extrusion through the pressing protrusion 222 during the process of the clamping member being inserted into the clamping cavity 133, so that the cooperation between the limiting member 132 and the clamping member is more compact, reducing the risk of loosening or falling off due to loose connection, and achieving the purpose of improving the connection stability between the two. And the pressing protrusion 222 also reduces the contact area between the two on the basis of realizing their mutual extrusion, reduces the force that the user needs to apply to the shielding cover 20 during the disassembly and assembly process, and reduces the disassembly and assembly difficulty of the shielding cover 20.

[0096] It can be understood that, due to the relationship that any material has a certain plastic deformation ability, especially in the sheet metal structure, the metal sheet has good plastic deformation ability. Therefore, during the disassembly and assembly process, the restraint member 1321 and the clamping member are mutually extruded through the pressing protrusion 222, so that at least one of them undergoes plastic deformation. The plastic deformation can ensure that the clamping member can be smoothly inserted into the clamping cavity 133, and at the same time, the clamping member and the restraint member 1321 can maintain a state of mutually applying a pressing force, thus achieving the effect of pressing the shielding cover 20 onto the chassis main body 10 and ensuring its stability. In the above-described embodiment having the process hole 14, the process hole 14 also provides the activity space required for the plastic deformation of the clamping member, enabling the limiting member 132 to press the shielding cover 20 onto the surface of the chassis main body 10 through the clamping member, while avoiding the situation where it is difficult for the clamping member to be inserted into the clamping cavity 133 through the clamping port.

[0097] To facilitate the insertion of the clamping member into the clamping cavity 133 from the clamping port, the size of the clamping port should be set to be at least partially larger than the size of the clamping member. For example, Figure 3 - Figure 13 as shown, in some embodiments, at the position of the clamping port where the restraint member 1321 is located, a guiding plate 134 is further provided which is inclined in a direction away from the clamping cavity 133, so that the clamping port gradually narrows from a position away from the clamping cavity 133 towards a position close to the clamping cavity 133 until it matches the size of the clamping cavity 133. In this way, the end of the clamping port away from the clamping cavity 133 can provide a larger insertion space for the clamping member, and as the clamping member is gradually inserted, the clamping member can finally cooperate with the restraint member 1321 in the clamping cavity 133, without affecting the assembly strength of the first clamping portion 131 and the second clamping portion 221.

[0098] Based on the above-described embodiment in which the first disassembly and assembly component 13 includes a plurality of first clamping portions 131, and the second disassembly and assembly component 22 includes a plurality of second clamping portions 221, for example, Figure 3 - Figure 13 as shown, in this embodiment, in the disassembly and assembly direction of the chassis main body 10 and the shielding cover 20, at least two spaced-apart first clamping portions 131 are provided at the first end of the opening 12 of the chassis main body 10, and at least one first clamping portion 131 is provided on each of the opposite sides of the opening 12 of the chassis main body 10 in a direction parallel to the plane of the opening 12 and perpendicular to the disassembly and assembly direction of the chassis main body 10 and the shielding cover 20.

[0099] During the installation of the shielding cover 20, the shielding cover 20 moves in the assembly direction from the second end to the first end of the opening 12. Conversely, during the disassembly of the shielding cover 20, it moves in the disassembly direction from the first end to the second end of the opening 12. During this process, the corresponding second engaging portions 221 on the shielding cover 20 can be connected to the respective first engaging portions 131. The main reason for not setting the first engaging portion 131 at the position of the chassis main body 10 close to the second end of the opening 12 in this embodiment is that the disassembly and assembly direction of the shielding cover 20 in this embodiment is the connection direction between the first end and the second end of the opening 12. Therefore, even if the first engaging portion 131 is provided at the second end of the opening 12 of the chassis main body 10, during the disassembly and assembly of the shielding cover 20 with the chassis main body 10 in the corresponding direction, the first engaging portion 131 cannot play a role in restraining or disengaging the shielding cover 20.

[0100] For a more detailed understanding of this solution, in this embodiment, the first engaging portion 131 provided close to the first end of the opening 12 is defined as the first structure 136, and the first engaging portions 131 disposed on both sides of the opening 12 are defined as the second structure 137.

[0101] It should be understood that in order to ensure the installation stability of the shielding cover 20, the distance between the first structure 136 and the second structure 137 should be as large as possible. Therefore, as Figure 3 - Figure 13 shown, on the basis that the first structure 136 is provided close to the first end of the opening 12, the second structure 137 should be provided close to the second end of the opening 12 on one side of the opening 12 to achieve the purpose of increasing the force-bearing range of the chassis main body 10 and the shielding cover 20 in the assembled state.

[0102] It can be understood from the above content that the positions of the second clamping parts 221 arranged on the shielding cover 20 correspond to the first clamping parts 131. Since the first structure 136 is arranged near the first end of the opening 12, the clamping member can be directly inserted into the clamping cavity 133 thereof through the clamping interface, and the restraining member 1321 of the first structure 136 can be directly connected to the chassis body 10 through the connecting members 1322 on the opposite sides thereof, and the end of the limiting member 132 away from the clamping interface can be set to an open structure. Since the second structure 137 is located on one side of the opening 12, the snap-in extends toward the side of the shielding cover 20. Therefore, the limiting member 132 is located on the side close to the opening 12 and needs to have a avoidance opening 135 to avoid interference with the snap-in. Due to the existence of the avoidance opening 135, the restraining member 1321 in the second structure 137 cannot directly ensure its connection with the chassis body 10 by providing connecting members 1322 on opposite sides. Therefore, in this embodiment, the two connecting members 1322 on the restraining member 1321 are adjacently provided on its two sides, so that the snap-in can be smoothly inserted into the snap-in cavity 133 through the card interface, and at the same time, the snap-in can ensure its connection with the shielding cover 20 through the avoidance opening 135.

[0103] In one embodiment, in order to prevent the shielding cover 20 from being easily removed after being installed on the chassis body 10, Figure 3 - Figure 13 As shown, the chassis body 10 is further provided with a limiting assembly 15 at the second end of the opening 12. When the shielding cover 20 is installed on the chassis body 10, the limiting assembly 15 and the first structure 136 are respectively located at both ends of the shielding cover 20. When the shielding cover 20 is installed on the chassis body 10, the limiting assembly 15 is located at one end of the shielding cover 20, and is used to limit the shielding cover 20 from being separated from the chassis body 10, constrain the direction in which the shielding cover 20 is detached from the chassis body 10, and prevent the shielding cover 20 from being easily separated from the chassis body 10 along the disassembly direction.

[0104] It is understandable that, when the shielding cover 20 is installed on the chassis body 10, the present embodiment has no strict limitations or requirements on the matching relationship between the limit assembly 15 and the shielding cover 20. They can be against each other or have a certain gap, as long as they exist on the disassembly path of the shielding cover 20.

[0105] Due to the existence of the limit assembly 15, during the process of the shielding cover 20 being detached from the chassis body 10, the shielding cover 20 needs to be first pulled a certain distance away from the chassis body 10 so that the end of the shielding cover 20 close to the limit assembly 15 is offset from the limit assembly 15 on the disassembly path, and then a pulling force in the disassembly direction is applied to the shielding cover 20 to allow the shielding cover 20 to be detached from the chassis body 10. Of course, during the process of the shielding cover 20 being pulled away from the chassis body 10, the moving distance will not be too large, and it will not have much requirement on the space size outside the chassis body 10. In other words, this operation will not affect the technical effect of the disassembly and assembly structure reflected in the above content.

[0106] In one embodiment, the limiting assembly 15 includes a plurality of limiting protrusions 151, each of which protrudes from the surface of the chassis body 10 in a direction away from the accommodating cavity 11, ensuring that after the shielding cover 20 is assembled in place, each of the limiting protrusions 151 can block the disassembly path of the shielding cover 20, and the plurality of limiting protrusions 151 are spaced apart along the edge of the second end of the opening 12, and multiple locations on one side of the shielding cover 20 close to the limiting assembly 15 can be respectively constrained by independent limiting protrusions 151, thereby making the installation state of the shielding cover 20 more stable.

[0107] Based on any of the above implementation methods, please refer to the attached manual. Figure 3 - Figure 4 The shielding cover 20 includes a baffle plate 23 and a support plate 24. The support plate 24 is arranged around the edge of the baffle plate 23, and the support plate 24 is arranged at an angle to the baffle plate 23 so that the baffle plate 23 and the support plate 24 enclose the above-mentioned expansion cavity 21, and the side edge of the support plate 24 away from the baffle plate 23 defines the cavity opening of the expansion cavity 21.

[0108] The length of the support plate 24 determines the depth of the expansion cavity 21 and ensures the structural strength of the shielding cover 20. At the same time, a folding plate 25 is provided on the side of the support plate 24 away from the baffle 23, which is arranged away from the expansion cavity 21. During the assembly process of the shielding cover 20 and the chassis body 10, the folding plate 25 is basically in contact with the plane where the opening 12 is located, thereby expanding the contact area between the shielding cover 20 and the chassis body 10 to improve the stability of the shielding cover 20 on the chassis body 10. At the same time, the folding plate 25 and the support plate 24, as well as the support plate 24 and the baffle 23, are both designed with an angle, which can further improve the structural strength between any two of the above, and make the physical protection performance of the shielding cover 20 more superior.

[0109] When the shielding cover 20 is connected to the chassis body 10 via the disassembly structure, the second disassembly component 22 is disposed on the folding plate 25 .

[0110] Please continue to refer to the instruction manual Figure 3 - Figure 4, a plurality of heat dissipation holes 231 communicating with the expansion cavity 21 are evenly arranged on the side of the shielding cover 20 away from the chassis main body 10, so as to improve the heat dissipation performance of the graphics card 30 by opening the heat dissipation holes 231 on the baffle 23 on the basis of ensuring that the shielding cover 20 has sufficient structural strength through the above structure.

[0111] In summary, in the embodiment of the desktop computer chassis of this embodiment, the graphics card 30 can be installed at one end on the front panel 16, so that the other end extends towards the rear panel 17 and protrudes through the opening 12 from the rear panel 17, and the protruding part of the graphics card 30 can be protected by the shielding cover 20. This not only improves the compatibility of the chassis with different model sizes of the graphics card 30, but also ensures that the graphics card 30 can stably provide the corresponding matching performance, thus enhancing the user experience.
