Description

Technical Field

[0001] This utility model relates to the field of computer assembly technology, and in particular to a chassis structure with the power supply installed in the front. Background Technology

[0002] As computer hardware performance continues to improve, its power consumption and heat generation also increase significantly, making the heat dissipation efficiency inside the chassis a key factor affecting system stability. At the same time, users are increasingly demanding easier cable management and a more aesthetically pleasing overall appearance within the chassis. Therefore, the market urgently needs a chassis structure solution that can optimize airflow and simplify the installation process within limited space.

[0003] In most common computer case designs, the power supply is typically bottom-mounted, meaning it's installed below the motherboard. In this configuration, the power supply uses its own fan to draw air from inside the case for cooling. However, since high-performance graphics cards are also located above the motherboard and generate significant heat, the rising airflow from them is directly drawn into the power supply below. This forces the power supply to not only handle its own heat but also bear the additional heat load from the graphics card, resulting in localized heat buildup. This severely impacts the cooling efficiency and long-term stability of both the power supply and the graphics card.

[0004] In summary, due to the design and construction of existing technologies, heat accumulation occurs between the power supply and the graphics card, resulting in low heat dissipation efficiency and poor operational stability. Utility Model Content

[0005] The main purpose of this invention is to propose a chassis structure with the power supply installed in the front, which aims to solve the technical problems of low heat dissipation efficiency and poor working stability in the prior art.

[0006] To achieve the above objectives, this utility model proposes a chassis structure with a front-mounted power supply, comprising: an outer frame configured as the external structure of the chassis, the outer frame including a front panel, a top panel, a first side panel, a second side panel, a rear panel, and a bottom panel;

[0007] The motherboard is configured to house the motherboard, graphics card, power supply, and hard drive. The motherboard includes a first mounting plate and a second mounting plate fixed on the same side. The first mounting plate is further away from the front panel than the second mounting plate. The first mounting plate has a first mounting position for mounting the motherboard and a second mounting position for mounting the graphics card. The second mounting plate, facing the first side panel, has a third mounting position for mounting the power supply and a fourth mounting position for mounting the hard drive. The third mounting position is located above the fourth mounting position. A removable power supply cover is located on the top panel above the third mounting position. The power supply cover is configured to work in conjunction with the first side panel and the third mounting position for power supply installation.

[0008] Furthermore, the front panel and the second side panel are attached to the outer frame via snap-fit ​​connections.

[0009] Furthermore, the top plate and the main board are provided with a snap-fit ​​groove on the side facing the front plate, and the front plate and the second side plate are provided with snap-fit ​​structures respectively. The snap-fit ​​structures extend into the snap-fit ​​groove to form the snap-fit ​​connection.

[0010] Furthermore, the snap-fit ​​groove is constructed as a groove-shaped structure that is narrow in the middle and wide on both sides in the vertical direction, and the snap-fit ​​structure extends into the middle of the snap-fit ​​groove to form a snap-fit.

[0011] Furthermore, the buckle groove has a recess in the narrow middle section to facilitate the engagement of the buckle structure, and the recess is located at the upper and lower ends of the narrow middle section.

[0012] Furthermore, the buckle structure is circular.

[0013] Furthermore, the first side panel is configured as a multi-mesh panel for heat dissipation.

[0014] Furthermore, a passage for the passage of wires is defined between the first mounting plate and the second mounting plate.

[0015] Furthermore, the base plate is provided with a fan mounting position and a dustproof mesh. The dustproof mesh is arranged along the direction from the front plate to the rear plate, and the fan mounting positions are sequentially arranged on both sides of the dustproof mesh along the direction of the first side plate and the second side plate.

[0016] Furthermore, the second mounting plate has a figure mounting position on the opposite side of the third and fourth mounting positions, and the second side plate is defined as a transparent and visible structure.

[0017] This utility model's technical solution includes an outer frame and a motherboard. The motherboard includes a first mounting plate and a second mounting plate fixed on the same side. The first mounting plate has mounting positions for mounting the motherboard and graphics card. The second mounting plate has a third mounting position for mounting the power supply and a fourth mounting position below it, facing the first side plate. A removable power supply cover is located on the top plate above the third mounting position. This power supply cover is configured to work with the first side plate and the third mounting position to complete the power supply installation. By placing the power supply area at the front and separating it from the motherboard and graphics card areas, this utility model physically blocks the mutual thermal interference between the main heat sources, constructing an independent heat dissipation path, thus providing the computer with high heat dissipation efficiency and strong operational stability during operation.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0030] This utility model proposes a chassis structure with the power supply installed at the front.

[0031] In this embodiment of the utility model, such as Figures 1 to 7 As shown, the chassis structure includes an outer frame 1 and a motherboard 2. The outer frame 1 serves as the external structure of the chassis and includes a front panel 11, a top panel 12, a first side panel 13, a second side panel 14, a rear panel 15, and a bottom panel 16. The motherboard 2 is used to install the motherboard, graphics card, power supply, and hard drive. The motherboard 2 includes a first mounting plate 21 and a second mounting plate 22 fixed on the same side. The first mounting plate 21 is further away from the front panel 11 than the second mounting plate 22. The first mounting plate 21 has a first mounting position 211 for installing the motherboard and a second mounting position 212 for installing the graphics card. The second mounting plate 22 has a third mounting position 221 for installing the power supply and a fourth mounting position 222 for installing the hard drive in the direction facing the first side panel 13. The third mounting position 221 is located above the fourth mounting position 222. Meanwhile, the top panel 12 has a removable power supply cover 3 above the third mounting position 221. The power supply cover 3 is configured to cooperate with the first side panel 13 and the third mounting position 221 to install the power supply.

[0032] This layout changes the traditional vertical stacking heat distribution pattern of the power supply and graphics card in a chassis. By placing the second mounting plate 22 and its third and fourth mounting slots 221 at the front, forming a parallel layout with the motherboard and graphics card areas on the first mounting plate 21, the two main heat sources are completely isolated physically. This partitioned design allows the power supply to directly draw in cool air from the front panel 11 and the first side panel 13 through its mounting orientation towards the first side panel 13, forming an independent air intake channel and completely avoiding the intake of high-temperature exhaust gases from the graphics card cooling area. The coordinated installation design of the removable power supply shroud 3 at the top and the first side panel 13 creates a unique installation path, breaking through the limitations of traditional installation methods, and together with the partitioned layout, constructs a highly efficient parallel cooling system. This structural innovation allows the power supply and graphics card to operate simultaneously in their optimal temperature environments, significantly improving the overall cooling efficiency and providing a more stable and reliable working foundation for high-performance hardware.

[0033] In some embodiments of this utility model, the front panel 11 and the second side panel 14 are installed on the outer frame 1 via a snap-fit ​​connection. This snap-fit ​​connection eliminates the need for traditional screw fixing, achieving rapid assembly and disassembly through the elastic interlocking of components. Compared to traditional connection methods, this design significantly reduces tool reliance and operation time, making the panel assembly and disassembly process more user-friendly. Furthermore, when the chassis is subjected to vibration or temperature changes, the slight deformation between the snap-fit ​​interfaces effectively absorbs stress, avoiding the risk of panel deformation caused by localized stress concentration, and improving the overall stability and reliability of the structure.

[0034] Specifically, the top plate 12 and the main board 2 are provided with snap-fit ​​grooves 4 facing the front plate 11, and the front plate 11 and the second side plate 14 are respectively provided with snap-fit ​​structures 5. The snap-fit ​​structures 5 extend into the snap-fit ​​grooves 4 to form the snap-fit ​​connection. The cooperation between the snap-fit ​​grooves 4 and the snap-fit ​​structures 5 establishes a guiding self-locking mechanism. During assembly, when the snap-fit ​​structure 5 extends into the snap-fit ​​groove 4 at a specific angle, the groove wall guides the snap-fit, causing it to automatically lock after reaching the predetermined position. This connection method not only enables blind operation but also maintains stability superior to point-contact connections in vibration environments through the surface contact cooperation characteristics. In particular, this design allows for the simultaneous fixing of multiple connection points within a limited space, solving the technical bottleneck of traditional screw fixing requiring alignment of holes one by one, and providing a structural basis for rapid assembly and maintenance of the chassis. Furthermore, there are multiple embodiments for the arrangement of the snap-fit ​​groove 4 and the snap-fit ​​structure 5. For example, the top plate 12 and the snap-fit ​​groove 4 can be integrally formed or separately set. Similarly, the front plate 11 and the second side plate 14 can be integrally formed or separately set. In the separately set embodiment, the snap-fit ​​groove 4 and the snap-fit ​​structure 5 can be represented as a single mounting piece or mounting block, and connected to the outer frame 1 by threaded connection or by snap-fit ​​connection. Figure 6 As shown, the snap-fit ​​groove 4 is integrally formed on part of the top plate 12 and the main plate 2, and the snap-fit ​​structure 5 is formed on the mounting plate.

[0035] More specifically, the snap-fit ​​groove 4 is constructed as a groove-shaped structure that is narrow in the middle and wide on both sides in the vertical direction. The snap-fit ​​structure 5 extends into the middle of the snap-fit ​​groove 4 to form a snap-fit. Understandably, when the snap-fit ​​structure 5 extends into the groove, the wider areas on both sides provide the necessary assembly tolerance, reducing the requirements for precise alignment; while after the snap-fit ​​structure 5 reaches the narrow middle area, the groove wall exerts radial constraint on the snap-fit ​​structure 5, forming a stable mating connection. This gradual locking design not only ensures the secure fixing of the connector under normal working conditions, but also provides a buffering effect through the elastic deformation of the narrow area when subjected to abnormal external forces, effectively preventing sudden failure of the connection structure. This design improves the reliability of the connection node under dynamic loads while ensuring ease of assembly.

[0036] More specifically, the snap-fit ​​groove 4 has recesses 41 in its narrow middle section to facilitate the engagement of the snap-fit ​​structure 5. These recesses 41 are located at both the upper and lower ends of the narrow middle section. The recesses 41 play a guiding and positioning role during the assembly of the snap-fit ​​structure 5. The recesses 41 at both ends of the narrow area provide clear travel nodes for the snap-fit ​​structure 5. When the snap-fit ​​structure 5 passes through the recesses 41, it generates noticeable force feedback, providing the operator with a tactile indication of proper assembly. This design reduces uncertainty during assembly, allowing even non-professionals to achieve precise and reliable connections. It is worth noting that the shape and size of the recesses 41 can be optimized based on material properties. For example, using a rounded contour in the recesses 41 can effectively reduce stress concentration and prevent plastic deformation during repeated assembly and disassembly, thereby extending the service life of the connection structure. This design ensures connection reliability while improving product maintainability and user experience.

[0037] In some embodiments of this invention, the snap-fit ​​structure 5 is circular. Understandably, the circular cross-section of the snap-fit ​​structure 5 represents an optimization of the assembly process. The circular shape eliminates directional constraints, allowing the snap-fit ​​structure 5 to achieve smooth contact throughout the entire circumference when inserted into the snap-fit ​​groove 4, reducing assembly difficulty. This geometric feature forms an ideal fit with the aforementioned narrow groove segment with the recess 41—when the circular snap-fit ​​structure 5 passes through the recess 41, its continuous curvature surface makes progressive contact with the contour of the recess 41, effectively reducing local contact stress. More importantly, the circular structure will not experience sharp edge wear due to repeated disassembly and assembly during long-term use, maintaining the durability of connection reliability. From a manufacturing perspective, the axisymmetric characteristics of the circular snap-fit ​​structure 5 make it easier to ensure dimensional accuracy during injection molding and less prone to stress concentration defects, providing a process advantage for mass production.

[0038] Those skilled in the art will understand that the snap-fit ​​structure 5 can also adopt other suitable geometric shapes. For example, a snap-fit ​​structure 5 with a regular polygonal (such as a regular hexagonal) cross-section can provide higher torsional resistance while maintaining the advantage of non-directional assembly, as the planar contact between its edges and the narrow section of the snap-fit ​​groove 4 provides a more effective method. A cross-sectional shape combining an ellipse or semi-circle with a plane can provide differentiated insertion and holding forces in specific directions, achieving the function of preventing incorrect assembly. Furthermore, trapezoidal or wedge-shaped structures can utilize their inclined surfaces to achieve smoother guidance and self-locking effects. The selection of these alternative shapes is based on a comprehensive consideration of factors such as assembly guidance, torsional stiffness, anti-misassembly requirements, and manufacturability. All of them, within the framework of the engagement mechanism between the snap-fit ​​structure 5 and the snap-fit ​​groove 4, achieve the core objective of convenient assembly and reliable connection in different ways.

[0039] In some embodiments of this invention, the first side panel 13 is configured as a multi-mesh panel for heat dissipation. It is worth noting that the multi-mesh panel design, together with the aforementioned front-mounted power supply layout, creates a synergistic heat dissipation effect. When the power supply is installed in the front-mounted third mounting position 221, the heat dissipation airflow is directly aligned with the mesh area of ​​the first side panel 13, allowing external cool air to directly and efficiently enter the power supply air intake through the mesh. This directional ventilation design significantly shortens the cooling airflow path, reduces wind resistance loss, and effectively prevents the recirculation of hot air inside the chassis.

[0040] Furthermore, the aperture ratio and aperture size of the multi-mesh panel can be optimized according to heat dissipation requirements. While ensuring structural strength, increasing the mesh area can further improve air intake efficiency; while adopting a gradient or partitioned hole layout can achieve precise heat dissipation for different heat source components such as power supplies and hard drives.

[0041] In some embodiments of this invention, a through-hole 23 for cable routing is defined between the first mounting plate 21 and the second mounting plate 22. The through-hole 23 solves the cable management problem caused by the front-mounted power supply layout. Since the power supply is moved to the front second mounting plate 22, its output cables need to reach the motherboard located on the rear first mounting plate 21. The through-hole 23 provides a dedicated, centralized cable routing channel for these cables. This structure contrasts with the disordered cable routing of existing technologies, significantly improving the tidiness of the internal space by integrating scattered and messy wiring into a single, orderly path. Specifically, the through-hole 23 can be implemented in various ways; it can be located on the first mounting plate 21 or the second mounting plate 22, or defined by a notch-type structure between the first mounting plate 21 and the second mounting plate 22, such as... Figure 4 and Figure 5 As shown, port 23 is located on the second mounting plate.

[0042] In some embodiments of this utility model, the base plate 16 is provided with fan mounting positions 6 and dustproof mesh 7. The dustproof mesh 7 is arranged along the direction from the front plate 11 to the rear plate 15, and the fan mounting positions 6 are sequentially arranged on both sides of the dustproof mesh 7 along the direction of the first side plate 13 and the second side plate 14. Understandably, the dustproof mesh 7 extends in a forward-backward direction, consistent with the main direction of the overall cooling airflow of the chassis, effectively blocking larger particulate contaminants while introducing cooling airflow. The design of the fan mounting positions 6 located on both sides of the mesh allows the cooling airflow to cover the entire area of ​​the base plate 16 more evenly. Compared with the traditional single-sided fan layout, this arrangement reduces the heat dissipation dead zones inside the chassis. When the fans on both sides work together, a balanced airflow field can be formed below the hard drive mounting area, avoiding localized overheating caused by uneven airflow. At the same time, this design provides flexibility for different cooling requirements—users can choose to install a single-sided fan or dual-sided fans according to actual needs, or even configure fans with different air pressure characteristics on both sides to optimize the cooling effect of specific areas. In addition, from a dust prevention perspective, the continuously arranged dustproof mesh 7 not only provides a larger effective ventilation area, but its regular array arrangement also makes it easier to clean and maintain daily.

[0043] Furthermore, the top plate 12 also features a dust filter mesh 7. The shared dust filter mesh 7 on both the top plate 12 and the bottom plate 16 helps reduce dust intrusion. The top plate 12's dust filter mesh 7 primarily targets fine dust particles carried to the top of the chassis by the rising effect of hot air, while the bottom plate 16's dust filter mesh 7 focuses on intercepting larger particulate contaminants sucked in by the bottom fan. This coordinated top-to-bottom layout effectively covers the chassis's main air exchange paths. It's worth noting that the dust filter mesh 7 on the top plate 12 and bottom plate 16 can be designed differently in practice. The bottom plate 16's dust filter mesh 7 can use a higher-density mesh fabric to enhance the filtration of larger particles such as ground dust; while the top plate 12's dust filter mesh 7 can use a mesh structure with slightly larger pores, ensuring dust prevention while also allowing for smooth exhaust of hot air from the top. This differentiated design maximizes dust prevention while avoiding the impact of overly dense dust filters on overall heat dissipation efficiency.

[0044] Furthermore, in order to enhance the dustproof effect, a dustproof net 8 is provided above the top plate 12. The main body of the top plate 12 is recessed downward to facilitate the placement of the dustproof net 8. The dustproof net 8 is existing technology and will not be described in detail here.

[0045] In some embodiments of this utility model, the second mounting plate 22 has a figurine mounting position 9 on the opposite side of the third mounting position 221 and the fourth mounting position 222, and the second side plate 14 is defined as a transparent and visible structure. The figurine mounting position 9 is fixed to the back of the second mounting plate 22 by a snap-fit ​​connection. This connection method allows the mounting position to be installed and removed without tools, providing convenience for users to adjust the display content. Furthermore, the figurine mounting position 9 can also be equipped with a standard threaded interface, which can be fixed with a single screw. Since the figurine mounting position 9 often has load-bearing requirements, this composite fixing method with snap-fit ​​as the main method and screw as the auxiliary method ensures both the convenience of daily display and the structural reliability during chassis movement or transportation. The anti-slip texture design on the surface of the mounting position can further enhance the stability of the display. The transparent second side plate 14 is preferably made of acrylic or glass material with high light transmittance and low deformation, which ensures both the clarity of the display effect and the structural strength of the chassis.

[0046] Furthermore, from a manufacturing perspective, the figure mounting position 9 can be manufactured either as a single piece with the second mounting plate or as a separate component. A separate design allows for flexible configuration based on user needs, while a single piece provides better structural strength. This scalable structural design enables diverse chassis functions while maintaining production economics.

[0047] The following content serves as an explanation of the working principle of this utility model:

[0048] When the computer is operating internally, the power supply and hard drive are concentrated in the front second mounting plate area 22, while the motherboard and graphics card are distributed in the rear first mounting plate area 21, forming a clear functional partition. This layout allows the power supply to directly draw low-temperature air from the front of the chassis and the mesh of the first side plate 13 through its mounting orientation towards the first side plate 13, establishing an independent air intake channel.

[0049] Meanwhile, the hot air generated by the graphics card rises along the natural convection direction and is exhausted through the top and rear panels 15. This creates physically isolated parallel cooling paths between the two main heat sources, fundamentally avoiding the problem of the power supply drawing in waste heat from the graphics card in traditional layouts. The combination of the bottom fan mounting position 6 and the dust filter 7 further enhances the overall airflow organization from bottom to top, providing auxiliary cooling for components such as the hard drive.

[0050] The installation design of the power supply cover 3 not only provides a convenient assembly method, but also, together with the first side panel 13, forms a dedicated heat dissipation environment for the power supply. The design of the port 23 ensures the orderly arrangement of power cables, avoiding obstruction of key airflow channels by stray cables. These features work together to build a highly efficient and coordinated heat dissipation system, significantly improving the overall heat dissipation performance and system stability.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
