Description

Technical Field

[0001] The utility model relates to the field of computer cases, in particular to an ITX computer case with an A4 structure. Background Art

[0002] In the prior art, the traditional ITX (mini-ITX) case design usually places the motherboard at the bottom or center of the case, and the power supply is located at the bottom or side of the case. This design provides basic hardware installation space in a compact case size, but there are some challenges in heat dissipation and cable management.

[0003] The heat dissipation of graphics cards in traditional ITX cases usually relies on fans or heat dissipation holes at the rear of the case. However, since the heat dissipation outlet at the rear of the graphics card is close to the motherboard inside the case, it is easy for heat to circulate inside the case, reducing the heat dissipation efficiency. Especially when running at high load, the heat generated by the graphics card cannot be discharged in time, causing the back of the motherboard to be heated by the ventilation and heat dissipation module design at the rear of the graphics card, resulting in hardware operation errors and heat accumulation that cannot be discharged in time.

[0004] In addition, the graphics card interface in traditional ITX cases is usually facing downwards, located on the expansion slot of the motherboard. This design requires users to bend over or flip the case when plugging in or out the graphics card, which increases the difficulty and inconvenience of operation. At the same time, in order to leave enough space for plugging and unplugging, users may need to lift the graphics card or move other hardware, which not only increases the complexity of installation, but also wastes valuable space inside the case. Summary of the invention

[0005] In order to solve the above problems, the utility model provides an ITX case with an A4 structure. The solution swaps the positions of the motherboard and the power supply, and places the power supply on top.

[0008] Furthermore, a first power supply bracket for sharing the weight of the power supply is provided in the power supply mounting area corresponding to the rear side plate, and a second power supply bracket for sharing the weight of the power supply is also provided on the top of the middle frame.

[0009] Furthermore, a graphics card fixing bracket is movably provided at the graphics card mounting area corresponding to the rear side plate for conveniently fastening the graphics card.

[0010] Furthermore, the graphics card fixing bracket includes a height adjustment bracket and a horizontal adjustment bracket, wherein the height adjustment bracket is an L-shaped structure, the other end of the height adjustment bracket is connected to a first adjustment plate, and the surface of the first adjustment plate is provided with a first waist hole extending along the spatial Y-axis, and the horizontal adjustment bracket is fixed to the first waist hole by bolts, and the surface of the horizontal adjustment bracket is provided with a second waist hole extending along the spatial X-axis; a back mounting hole is provided at the graphics card mounting area corresponding to the rear side plate, wherein a graphics card bracket adjustment panel is installed on the back mounting hole, and the surface of the graphics card bracket adjustment panel is provided with a third waist hole extending along the spatial Z-axis, wherein the height adjustment bracket is mounted on the first waist hole by screws.

[0011] Furthermore, a first extended installation panel is installed at the back mounting hole, a first extended installation pattern is arranged below the back mounting hole, and a second extended installation pattern is arranged at the rear side corresponding to the mainboard mounting area.

[0012] Furthermore, a graphics card installation panel for conveniently fastening the graphics card and exposing the graphics card interface is provided at the bottom plate corresponding to the graphics card installation area, and a third expansion installation panel is provided at the bottom plate corresponding to the motherboard installation area.

[0013] Furthermore, the front side plate is a first radiator bracket for installing the radiator, and the chassis frame also includes a right side plate, and the right side plate is a second radiator bracket for installing the radiator.

[0014] Furthermore, the chassis frame also includes a top frame, a front side cover, a right side cover, and a left light-transmitting member.

DETAILED DESCRIPTION

[0032] See also Figure 1-8As shown, the utility model relates to an I TX chassis of A4 structure, including a chassis frame, wherein the chassis frame includes a power supply mounting area for mounting a power supply 32 module, a graphics card mounting area for mounting a graphics card 31, and a motherboard mounting area for mounting a motherboard 34, wherein the power supply mounting area is located above the motherboard mounting area, and the graphics card mounting area is located on one side of the motherboard mounting area so that the air outlet of the graphics card 31 is aligned with the air inlet of the power supply 32. At the same time, a foot pad accessory 6 is provided at the bottom of the chassis frame, and a plurality of interfaces 61 are provided on the surface of the foot pad accessory 6.

[0033] Compared with the traditional ITX chassis, this solution swaps the positions of the motherboard 34 and the power supply 32 and places the power supply 32 on top. The innovation of this design is that it allows the heat dissipation outlet at the rear of the graphics card 31 to directly face the air inlet of the power supply 32, thereby effectively forming a heat dissipation duct. Such an air duct design can greatly improve the heat dissipation efficiency, quickly conduct the heat generated by the graphics card 31, avoid the accumulation of heat inside the chassis, and also reduce the risk of hardware operation errors caused by overheating of the motherboard 34.

[0034] Through the extension cable, the graphics card interface 61 that was originally facing downward is connected to the foot pad accessory 6, so that the direction of the interface 61 is changed to backward. This design innovation not only makes it convenient for users to plug and unplug wires and reduces the difficulty of plugging and unplugging, but also eliminates the need to raise the graphics card 31 to leave enough space, thereby saving space inside the chassis. When the chassis and competing products have the same height design, due to the optimization of the internal space, this solution can support a longer graphics card 31 length, greatly increasing the compatibility of the graphics card 31. This means that users can choose a higher-level graphics card 31 according to their needs without worrying about insufficient space in the chassis. In addition, changing the interface 61 to face backward is also conducive to improving the cable management of the chassis, making the interior of the chassis more tidy and beautiful.

[0035] The chassis frame specifically includes a bottom plate 2, a front side plate 4, a rear side plate 1, and a middle frame 3. The rear side plate 1 is mounted on the rear side of the bottom plate 2, and the middle frame 3 is vertically arranged on the surface of the rear side plate 1 and divides the rear side plate 1 into two left and right areas, wherein the upper part of the left area constitutes a power supply 32 mounting area, the lower part of the left area constitutes a motherboard mounting area, and the right area constitutes a graphics card mounting area.

[0036] The frame of this A4 structure I TX chassis consists of a bottom plate 2, a front side plate 4, a rear side plate 1 and a middle frame 3. The rear side plate 1 is mounted on the rear side of the bottom plate 2, and the middle frame 3 is vertically arranged on the rear side plate 1, dividing the rear side plate 1 into two areas, the left and right areas. The upper part of the left area constitutes the power supply mounting area, the lower part is the motherboard mounting area, and the right area is the graphics card mounting area.

[0037] This design optimizes the heat dissipation performance. By placing the power supply 32 above the motherboard 34 and aligning it with the heat dissipation outlet of the graphics card 31, an effective heat dissipation duct is formed, which reduces the temperature inside the chassis. At the same time, this layout also improves hardware compatibility and supports various specifications of I TX motherboards 34, small power supplies 32 and graphics cards 31. In addition, the optimized space layout allows users to install, remove and upgrade hardware more easily, improving the overall user experience.

[0038] Moreover, in the present specific embodiment, the rear side panel 1 is provided with a plurality of screw holes for mounting the middle frame 3, so the user can adjust the position of the middle frame 3 according to actual needs. For example, the middle frame 3 can be selectively placed in the center or moved to the motherboard mounting area to be compatible with thicker graphics cards.

[0039] Specifically discussed, the power supply mounting area corresponding to the rear side plate 1 is provided with a first power supply bracket 101 for sharing the weight of the power supply 32 , and the top of the middle frame 3 is also provided with a second power supply bracket 102 for sharing the weight of the power supply 32 .

[0040] See also Figure 9-10 Specifically, in this specific embodiment, an SFX power supply, an SFX-L power supply, or an ATX power supply can be adapted.

[0041] See also Fig. 9 A power supply fixing panel 108 is installed at the power supply mounting area corresponding to the rear side panel 1, wherein a first power supply bracket 101 for sharing the weight of the power supply 32 is fixed on the power supply fixing panel 108, and a second power supply bracket 102 at the top of the middle frame can be used as an option. When the power supply to be installed is a smaller-sized SFX power supply or SFX-L power supply, the first power supply bracket 101 can be used as a power supply support, and the extra second power supply bracket 102 can be not installed. If installed, the second power supply bracket 102 can also play the role of fixing the wire, that is, the wire can be routed from the position between the second power supply bracket 102 and the top of the middle frame. The first power supply bracket 101 is set in the power supply mounting area corresponding to the rear side panel 1. This position is selected to directly support the weight of the power supply 32 and prevent the power supply 32 from shaking or shifting in the chassis. The bracket is made of metal (such as aluminum alloy or steel) to ensure that it is sturdy and durable and can withstand the weight of the power supply 32 for a long time.

[0042] See also Fig.10In addition, when the power supply is a normal-sized ATX power supply, the corresponding power supply fixing panel 108 is directly disassembled, and the first power supply bracket 101 is not selected. The ATX power supply is directly assembled in the corresponding hole by screws, and the ATX power supply is supported only by the second power supply bracket 102. The second power supply bracket 102 is set on the top of the middle frame 3. Similar to the first power supply bracket 101, the bracket is also made of metal to ensure its load-bearing capacity and stability. In addition to sharing the weight of the power supply 32, the second power supply bracket 102 also enhances the load-bearing capacity of the middle frame 3, making the entire chassis structure more stable.

[0043] Specifically, a graphics card fixing bracket is provided at the graphics card mounting area corresponding to the rear side plate 1 for conveniently fastening the graphics card 31. Specifically, the graphics card fixing bracket is movably mounted on the rear side plate 1 for adapting to graphics cards of different sizes. Specifically discussed, the graphics card fixing bracket includes a height adjustment bracket 106 and a horizontal adjustment bracket 107, wherein the height adjustment bracket 106 is an L-shaped structure, the other end of the height adjustment bracket 106 is connected to a first adjustment plate 1061, and the surface of the first adjustment plate 1061 is provided with a first waist hole 1062 extending along the spatial Y-axis, and the horizontal adjustment bracket 107 is fixed to the first waist hole 1062 by bolts, and the surface of the horizontal adjustment bracket 107 is provided with a second waist hole 1063 extending along the spatial X-axis; a back mounting hole is provided at the graphics card mounting area corresponding to the rear side plate 1, wherein a graphics card bracket adjustment panel 103 is installed on the back mounting hole, and the surface of the graphics card bracket adjustment panel 103 is provided with a third waist hole 1031 extending along the spatial Z-axis, wherein the height adjustment bracket 106 is mounted on the first waist hole 1062 by screws.

[0044] Installation principle: install the graphics card bracket adjustment panel 103 on the back mounting hole of the rear side panel 1, and then fix the height adjustment bracket 106 on the third waist hole 1031 of the graphics card bracket adjustment panel 103 by screws, and realize adjustment in the Z-axis direction. At the same time, fix the horizontal adjustment bracket 107 on the first waist hole 1062 of the first adjustment plate 1061 by screws to realize adjustment along the Y-axis direction of space, and finally pass the screws through the second waist hole 1063 on the horizontal adjustment bracket 107, and finally connect it with the corresponding hole position of the graphics card 31, so as to realize the adaptation of graphics cards 31 of different sizes to achieve installation.

[0045] Specifically, a graphics card installation panel 22 is provided at the graphics card installation area corresponding to the bottom plate 2 for conveniently fastening the graphics card 31 and exposing the graphics card interface 61. At the graphics card installation area corresponding to the bottom plate 2, we designed a graphics card installation panel 22. The main functions of this panel include conveniently fastening the graphics card 31 and exposing the graphics card interface 61.

[0046] The graphics card installation panel 22 is provided with a series of screw holes for fixing the graphics card 31. The positions and sizes of these holes are precisely calculated to ensure that the graphics card 31 can be firmly installed in the chassis. By tightening the screws, the graphics card 31 can be tightly connected to the installation panel, thereby preventing the graphics card 31 from loosening or shaking during use. In order to facilitate the connection between the graphics card 31 and external devices, the graphics card installation panel 22 is provided with openings or grooves at appropriate positions. These openings or grooves allow the interfaces 61 (such as HDMI interface 61, DisplayPort interface 61, etc.) of the graphics card 31 to be fully exposed, thereby facilitating the user to connect and expand cables.

[0047] In this specific embodiment, we set a number of foot pad accessories 6 installed at the bottom of the chassis bottom plate 2, whose main function is to increase the height of the chassis and act as foot pads. This can not only increase the height of the chassis from the ground and enhance the heat dissipation performance, but also use the space between the raised base and the desktop for other designs. The material of the foot pad accessories 6 should be durable, non-slip and elastic to ensure the stability and safety of the chassis.

[0048] On the surface of the foot pad accessory 6, we design a number of interfaces 61, which are connected to the original interface 61 of the graphics card 31 through an extension line. Through this design, the graphics card 31 interface 61 originally facing downward is changed to face backward, toward a direction that is easier for users to approach and operate.

[0049] The type and number of interfaces 61 should be designed and configured according to the commonly used interfaces 61 of the graphics card 31, such as HDMI interface 61, DisplayPort interface 61, etc. At the same time, the position and layout of the interfaces 61 should be carefully planned to ensure that the cables are neatly arranged and easy to manage. Specifically, by changing the graphics card interface 61 to a rear-facing design, we can provide a longer installation space for the graphics card 31 without raising the graphics card 31. This allows the chassis to be compatible with longer graphics cards 31 while maintaining the same height design as other competing products, greatly increasing the compatibility of the graphics card 31. The traditional graphics card interface 61 downward design often leads to messy cables and difficult management. Our solution greatly optimizes cable management by changing the interface 61 to a rear-facing design and using an extension cable for connection, so that the cables can be neatly arranged at the back of the chassis. The rear-facing interface 61 design allows users to operate directly from the back of the chassis without bending over or reaching to the bottom of the chassis to plug and unplug the cables. This not only improves the convenience of operation, but also reduces the risk of hardware damage caused by improper operation. The design of the foot pad accessory 6 creates a certain space between the bottom of the chassis and the desktop, which helps to increase air circulation inside the chassis and improve heat dissipation performance. At the same time, the rearward interface 61 design also enables the cooling fan of the graphics card to better discharge heat outside the chassis.

[0050] The specific discussion also includes a foot pad accessory 6, wherein two foot pad accessories 6 are provided on the bottom surface of the base plate 2, and a surface of one foot pad accessory 6 is also provided with a plurality of IO interfaces 61, including a power button, a 3.5mm headphone jack, USB-A, and Type-C; and a surface of the other foot pad accessory 6 is also provided with a plurality of video interfaces 61, including DP and HDMI.

[0051] Specifically discussed, the front side plate 4 is a first cold row bracket for installing the cold row 33, and is also installed with a right side plate 5, and the right side plate 5 is a second cold row bracket for installing the cold row.

[0052] The front side panel 4 is designed to install a radiator, and its position and size are carefully planned to ensure that the radiator can effectively discharge heat outside the chassis. This design can make full use of the space in the front of the chassis and improve the heat dissipation efficiency. In addition to the front side panel 4, the right side panel 5 is also designed as a radiator bracket. This design allows players to install more radiators inside the chassis, thereby further improving the heat dissipation performance. At the same time, the position of the right side panel 5 also makes the radiator closer to the hardware that needs heat dissipation, thereby more effectively reducing its temperature.

[0053] The dual radiator 33 bracket design allows players to install more radiators 33 inside the chassis, thereby increasing the heat dissipation area and heat dissipation efficiency. This design allows the heat inside the chassis to be discharged faster, reducing the operating temperature of the hardware and improving the stability and reliability of the system. The dual radiator 33 bracket design allows the chassis to support higher-end and heat-generating hardware configurations. Whether it is an overclocked CPU, a high-end graphics card, or a multi-hard disk array, it can all get good heat dissipation support, thus ensuring the stable operation and performance of the system.

[0054] Specifically discussed, the chassis frame also includes a top frame 7, a front side cover 12, a right side cover 13, and a left light-transmitting member 14. The top frame 7 is connected to the tops of the front side panel 4, the rear side panel 1, and the right side panel 5, respectively, and the four side surfaces of the top frame 7 and the four side surfaces of the bottom plate 2 are pre-embedded with a plurality of first magnetic positioning blocks 71. The upper and lower ends of the front side cover 12 and the right side cover 13 are magnetically assembled with the corresponding first magnetic positioning blocks 71, and the upper and lower ends of the left light-transmitting member 14 are respectively equipped with metal edging 141, which are magnetically assembled with the first magnetic positioning blocks 71 on the left side of the top frame 7 and the left side of the bottom plate 2 through the metal edging 141.

[0055] The top frame 7 is the top structure of the chassis, and is connected to the top of the front side panel 4, the rear side panel 1, and the right side panel 5. A plurality of first magnetic positioning blocks 71 are embedded in the four side surfaces of the top frame 7 and the four side surfaces of the bottom panel 2. These magnetic positioning blocks are used to magnetically assemble with the front side cover 12, the right side cover 13, and the left light-transmitting member 14 to ensure the stable connection of each component.

[0056] The upper and lower ends of the front side cover 12 and the right side cover 13 are designed with magnetic structures that match the first magnetic positioning blocks 71 on the top frame 7 and the bottom plate 2. Through the magnetic attraction, the front side cover 12 and the right side cover 13 can be easily and accurately assembled with the top frame 7 and the bottom plate 2 without the use of additional fixing tools or screws, thereby improving the convenience and efficiency of installation.

[0057] As a side of the chassis, the left light-transmitting member 14 adopts a light-transmitting design, allowing the user to observe the hardware status inside the chassis. The upper and lower ends of the left light-transmitting member 14 are respectively equipped with metal edging 141. These metal edging 141 not only enhance the stability of the light-transmitting member, but also provide an interface 61 for magnetically attaching to the first magnetic positioning block 71 on the left side of the top frame 7 and the left side of the bottom plate 2. Through the magnetic connection between the metal edging 141 and the first magnetic positioning block 71, the left light-transmitting member 14 can be firmly installed on the left side of the chassis, ensuring the overall stability and sealing of the chassis. The left light-transmitting member 14 is made of imported high-transparency and high-hardness acrylic material and is matched with the metal edging 141. It not only has the texture of glass and a frameless shape, but also has excellent safety performance and stability. This design not only meets the user's requirements for the aesthetics of the chassis, but also ensures the safety of use.

[0058] Specifically, there are several staggered circular holes on the surface of the front side cover 12 and the right side cover 13. The circular hole design allows air to flow freely to form a heat dissipation channel. The staggered circular holes can maximize the heat dissipation area, thereby improving the heat dissipation efficiency. The increase in air inlets and outlets allows the hardware equipment to be cooled more effectively to avoid performance degradation or equipment damage caused by overheating. Adding a dustproof net can effectively prevent these external pollutants from entering the box and protect the internal hardware. The choice of the dustproof net can be based on the specific needs of the user and environmental conditions to ensure a balance between heat dissipation and dust prevention.

[0059] Specifically discussed, the chassis frame also includes a top cover assembly, wherein the top cover assembly includes a first cover fixing frame 8, a second cover fixing frame 9, a side connector 10, and a top cover 11, wherein the first cover fixing frame 8 is located above the second cover fixing frame 9, and the first cover fixing frame 8 and the second cover fixing frame 9 are connected by the side connector 10; in addition, a plurality of second magnetic positioning blocks 81 are pre-embedded in the surface of the first cover fixing frame 8, and the top cover 11 is magnetically mounted on the surface of the first cover fixing frame 8 through the second magnetic positioning blocks 81, and in addition, a plurality of third magnetic positioning blocks 91 are pre-embedded in the bottom of the second cover fixing frame 9, and the second cover fixing frame 9 is magnetically mounted on the surface of the top frame 7 through the third magnetic positioning blocks 91 and the first magnetic positioning blocks 71.

[0060] Through the design of the magnetic positioning block, the top cover 11 can be easily magnetically assembled with the first cover fixing frame 8 without the use of screws or other complicated fixing tools. This design greatly simplifies the installation process, allowing users to quickly complete installation or removal work, and improves the convenience of operation.

[0061] The first cover fixing frame 8 and the second cover fixing frame 9 are connected by the side connecting piece 10 to form a stable structure. This design not only enhances the overall strength of the top cover assembly, but also improves its ability to resist external impact, ensuring the stability and safety of the chassis.

[0062] Moreover, a frame installation slot 92 can be formed between the first cover fixing frame 8 and the second cover fixing frame 9. The interior of the frame installation slot 92 can be used to install hardware such as hard disks and fans by matching other fixing brackets.

[0063] Another method may also be used, such as merging the first cover fixing frame 8 and the second cover fixing frame 9 to form an integral frame without a groove, and then processing an inlay groove at the original position of the second cover fixing frame 9, and fitting the accessories into the corresponding inlay groove and locking them with screws.

[0064] The use of magnetic positioning blocks enables the top cover 11 to fit tightly with the fixed frame, thereby enhancing the sealing performance of the chassis. This design effectively prevents dust and other pollutants from entering the chassis, protecting the cleanliness and safety of the internal hardware. If necessary, a dust net can also be installed on the top cover 11 to further reduce the possibility of dust and mosquitoes entering, thereby improving the dustproof performance of the chassis.

[0065] The design of the top cover 11 can take into account the layout of the heat dissipation holes to ensure effective heat dissipation inside the chassis. By properly designing the location and size of the heat dissipation holes, good heat dissipation effects can be achieved while ensuring dustproof performance, reducing the operating temperature of the hardware and improving the stability and reliability of the system.

[0066] The side of the middle frame 3 is matched with the mainboard 34 through positioning bolts, and a wire-passing area is reserved between the mainboard 34 and the middle frame 3, which is convenient for hiding various wires in the middle, so that the wires are not exposed in the end, and the internal hardware is beautiful and simple. The side of the middle frame 3 is matched with the mainboard 34 through positioning bolts. This connection method ensures the stability and accuracy of the mainboard 34, so that the mainboard 34 can be firmly installed on the middle frame 3, avoiding hardware failures caused by looseness or misalignment.
