Description

Technical Field

[0001] This utility model relates to the field of computer chassis technology, specifically a computer chassis with front-facing interfaces that can be combined with peripherals. Background Technology

[0002] Most mainstream desktop computer cases currently follow standardized architectures such as ATX, ITX, and BTX. Their internal layout and external interface positions strictly correspond to the specifications of the motherboard and power supply. These cases typically use a metal frame and a closed side panel structure. The motherboard I / O ports and graphics card output ports are fixed to the rear of the case, with the interfaces exposed through pre-drilled openings in the I / O shield. External devices must be connected to the host via rear cables. These cases are widely used in fixed desktop computing environments in homes, offices, and industrial settings. In addition, there are a small number of RTX inverted structure cases, which optimize airflow by adjusting the motherboard mounting direction, but the interfaces still maintain a rear-mounted layout, not changing the fundamental method of external cable connection.

[0003] However, existing technical solutions have significant limitations: since all interfaces are concentrated at the back of the chassis, users need to walk around to the back of the chassis to plug and unplug peripherals, which not only makes it difficult to see the interface locations but also easily leads to incorrect cable connections or poor contact; multiple cables extend from the back of the chassis to different peripherals, causing messy and tangled cables on the desktop, which not only affects aesthetics but also poses safety hazards; at the same time, peripherals such as monitors, keyboards, and mice are independent and scattered from the host, and need to be disassembled and transported separately during relocation. In particular, the monitor screen lacks overall protection measures and is easily damaged by bumps during movement, which cannot meet the urgent needs of modern users for device portability and deployment efficiency in high-frequency mobile office or cross-location collaboration scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a computer chassis with front-facing interfaces that can be combined with peripherals, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a computer chassis with front-facing interfaces that can be combined with peripherals, comprising: a bottom case and a cover plate, wherein the bottom case and the cover plate are combined and connected to form a complete chassis for accommodating and fixing a motherboard, a power supply, and a graphics card; a front panel, wherein the front panel is disposed on the front side of the bottom case and the cover plate, and the front panel has at least one interface window, the position of which corresponds to the interface position of the motherboard and the graphics card housed in the bottom case; a keyboard tray, wherein the keyboard tray is detachably installed on the bottom or side of the bottom case for supporting a keyboard and a mouse; wherein the monitor and keyboard can be stored and attached to the outer surface of the cover plate, so that the chassis, monitor, and keyboard are combined into a whole, facilitating one-handed relocation via the handle on the front side of the front panel.

[0006] In one feasible implementation, a front baffle is also installed on the inner front side of the chassis. The front baffle is used to assist in fixing the motherboard and graphics card. The interior of the chassis also integrates an audio module, a side adapter network port, and a side adapter HDMI port. The side adapter network port and the side adapter HDMI port are respectively connected to the network interface on the motherboard and the HDMI interface on the graphics card from the front side of the chassis to the rear side of the chassis via extension cables.

[0007] In one feasible implementation, the cover plate is also equipped with a bracket for supporting the display, a DC power supply port, and a mobile phone wireless charging module.

[0008] The bracket is detachably fixed to the surface of the cover plate by bolts. The DC power supply port is electrically connected to the host power supply to provide power to the display. The mobile phone wireless charging module is electrically connected to the host power supply to wirelessly charge mobile devices.

[0009] In one feasible implementation, the bracket includes a combination base, a vertical pole, and a rotatable VESA mount connected in sequence. The connecting pivot between the combination base, the vertical pole, and the rotatable VESA mount is provided with an adjustable damping bolt / hinge. The adjustable damping bolt / hinge allows the bracket to extend, retract, and fold for positioning. The rotatable VESA mount is provided with a connection structure adapted to the standard VESA mounting holes on the back of the display.

[0010] In one feasible implementation, the bottom side of the base box is also provided with an air inlet and a grille for heat dissipation, and the surface of the cover plate is provided with heat dissipation holes for enhancing heat dissipation.

[0011] In one feasible implementation, each of the interface windows on the front panel is provided with a self-closing dustproof door on its inner side. The self-closing dustproof door is rotatably installed on the inner side of the front panel via a pivot and a spring, and can automatically close to prevent dust when no external device is connected. The front side of the front panel is also provided with a power button and a status indicator light.

[0012] In one feasible implementation, the keyboard tray includes a tray and a folding frame. One end of the folding frame is detachably fixed to a pre-set fixing hole on the bottom or side of the base box by bolts, and the other end is connected to the tray by bolts. The pivot of the folding frame is provided with an adjustable damping bolt / hinge, which allows the keyboard tray to be extended, folded, and its angle adjusted and positioned.

[0013] In one feasible implementation, the self-closing dustproof door may adopt a two-piece structure that opens vertically or horizontally.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This device places all the I / O interfaces of the motherboard and graphics card on the front panel of the chassis, and opens a dedicated interface window with a spring-loaded self-closing dustproof door, so that all peripheral cable plugging and unplugging operations can be completed intuitively from the front, completely solving the problems of difficult blind operation and messy cable tangling of traditional rear interface ports. At the same time, the self-closing dustproof door automatically closes when no device is connected, which not only protects the interface from dust intrusion, but also stores frequently plugged-in devices such as USB flash drives and encryption modules inside the panel to avoid damage from bumps.

[0015] With an adjustable damping bracket and modular keyboard tray integrated into the cover, the monitor can be rigidly connected to the chassis according to the VESA standard and the viewing angle can be flexibly adjusted. The keyboard and mouse can also be folded and stored in the outline of the host, forming a compact structure of host-monitor-keyboard-mouse integration during relocation, effectively protecting the LCD screen from transportation damage and greatly improving the overall mobility and storage efficiency of the device. Combined with wireless peripherals and wireless video transmission technology, it can also realize a completely wireless desktop deployment that relies on only a single power cord, completely eliminating the problem of multiple tangled and messy cables from the physical connection level, and ultimately achieving multiple improvements in ease of operation, space utilization and portability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a computer case with front-facing interfaces that can be combined with peripherals, including: a bottom case 1, a cover plate 2, a front panel 3, and a keyboard tray 4. The bottom case 1 and the cover plate 2 are combined and connected to form a complete case for accommodating and fixing the motherboard, power supply, and graphics card. The front panel 3 is located on the front side of the bottom case 1 and the cover plate 2, and at least one interface window 31 is provided on the front panel 3. The position of the interface window 31 corresponds to the interface position of the motherboard and graphics card housed in the bottom case 1. The keyboard tray 4 is detachably installed on the bottom or side of the bottom case 1 to support the keyboard and mouse. The monitor and keyboard can be stored and attached to the outer surface of the cover plate 2, so that the case, monitor, and keyboard are combined into a whole, which is convenient for one-handed movement by means of the handle 33 on the front side of the front panel 3.

[0024] It should be noted that the core components such as the motherboard, power supply, and graphics card are installed and fixed in their designated positions inside the bottom case 1, ensuring that all I / O interfaces of the motherboard and graphics card face the front of the case. The cover plate 2 is then combined with the already assembled bottom case 1 to form a complete and enclosed case, providing physical protection and support for the internal hardware. After assembly, the front panel 3 is installed, with the interface window 31 aligned with and exposing the various interfaces of the motherboard and graphics card inside the bottom case 1. This allows for convenient plugging and unplugging of all external device cables from the front of the case, completely changing the traditional method of blind operation from the rear of the case. Depending on the usage scenario and user preference, the keyboard tray 4 can be selectively installed on the bottom or side of the bottom case 1, providing a stable support platform for the keyboard and mouse. Throughout the usage cycle, if the entire system needs to be moved or relocated, the keyboard and monitor can be quickly folded so that their surfaces are flush against the cover plate 2, greatly enhancing portability.

[0025] In some examples, the bottom case 1 is further equipped with a front baffle 11 on the inner front side. The front baffle 11 is used to assist in fixing the motherboard and graphics card. The bottom case 1 also integrates an audio module, a side adapter network port 12, and a side adapter HDMI signal port. The side adapter network port 12 and the side adapter HDMI signal port are respectively connected to the network interface on the motherboard and the HDMI interface on the graphics card from the front of the bottom case 1 to the rear side of the chassis via extension cables.

[0026] It should be noted that the speaker module inside the bottom case 1 is directly connected to the audio interface on the motherboard via internal cables to receive and play audio signals, eliminating the need for external speaker cables. For network and video signal connections, users can insert the network cable into the side adapter port 12 located at the rear of the chassis. The side adapter port 12 then uses an extension cable pre-installed inside the bottom case 1 to seamlessly transfer the signal to the motherboard network interface located at the front of the chassis. Similarly, users can insert the monitor signal cable into the adjacent side adapter HDMI signal port. The side adapter HDMI signal port also uses an internal extension cable to transfer the video signal to the graphics card HDMI output interface located at the front. This achieves the dual advantages of having all major interfaces concentrated at the front for easy plugging and unplugging, and the final cable outlet located at the rear side for easy cable management.

[0027] In some examples, the cover plate 2 is further equipped with a bracket 21 for supporting the display, a DC power supply port, and a mobile phone wireless charging module 10; the bracket 21 is detachably fixed to the surface of the cover plate 2 by bolts, the DC power supply port is electrically connected to the host power supply to provide power to the display, and the mobile phone wireless charging module 10 is electrically connected to the host power supply to wirelessly charge the mobile device.

[0028] It should be noted that during use, the user first securely installs the monitor bracket 21 onto the designated position on the surface of the cover plate 2 using bolts, and then adjusts the adjustable damping bolts / hinges at each joint of the bracket 21 to set the appropriate support force, thereby flexibly raising, lowering, and rotating the monitor to the optimal viewing angle and reliably fixing it in place. When the monitor needs to be used, the user only needs to connect one end of the monitor's dedicated DC power cord to the monitor and insert the other end into the DC power port on the cover plate 2. The DC power port directly draws power from the host power supply through the internal cable, thus providing a stable power supply to the monitor, eliminating the hassle of connecting a separate monitor power adapter. During daily computer use, if the user needs to charge their mobile phone, they can directly place the wireless charging-enabled mobile phone on the wireless charging module 10 marked with a wireless charging area on the surface of the cover plate 2. The wireless charging module 10 then converts the electrical energy from the host power supply into an electromagnetic field through the principle of electromagnetic induction, penetrating the mobile phone casing to conveniently wirelessly charge the mobile phone battery without the need for any data cable.

[0029] In some examples, the bracket 21 further includes a combination base, a vertical pole, and a rotatable VESA mount connected in sequence. The connecting pivot between the combination base, the vertical pole, and the rotatable VESA mount is provided with an adjustable damping bolt / hinge. The adjustable damping bolt / hinge allows the bracket 21 to be extended, retracted, and folded for positioning. The rotatable VESA mount is provided with a connection structure adapted to the standard VESA mounting holes on the back of the display.

[0030] It should be noted that the user first uses bolts to securely connect the standard VESA mounting holes on the back of the monitor to the rotatable VESA mount at the top of the bracket 21. Then, the user can adjust the height of the monitor by rotating the adjustable bolts to change the resistance of the pivot between the stand and the mounting base, thereby raising or lowering the stand to a suitable height and securing it reliably. Simultaneously, the user can also adjust the resistance of the pivot between the rotatable VESA mount and the stand by rotating another set of bolts, thus freely changing the monitor's tilt angle or rotating it laterally to the optimal viewing position and maintaining stability. When relocation or storage is required, the monitor can be pressed and folded so that its surface fits snugly against the cover plate 2, greatly reducing the space occupied by the entire chassis.

[0031] In some examples, the bottom side of the base box 1 is further provided with air intake holes and grilles for heat dissipation, and the surface of the cover plate 2 is provided with heat dissipation holes to enhance the heat dissipation effect.

[0032] It should be noted that the heat generated by the electronic components inside the chassis 1 during operation is effectively discharged to the external environment of the chassis through numerous heat dissipation holes; at the same time, air is continuously drawn into the chassis from the air intake holes with protective grilles set on the bottom and sides of the chassis 1; after entering, the cold air flows over the surface of the heat-generating components, absorbs and carries away the moving heat, and lowers its temperature to maintain stable operation.

[0033] In some examples, each interface window 31 of the front panel 3 is further provided with a self-closing dustproof door 32 on the inner side. The self-closing dustproof door 32 is rotatably installed on the inner side of the front panel 3 by means of a pivot and a spring, and can automatically close to prevent dust when there is no external device connected. The front side of the front panel 3 is also provided with a handle 33, a power button and a status indicator light.

[0034] It should be noted that when a user needs to connect an external device, aligning the device plug with and inserting it into the interface window 31, the plug pushes the inner self-closing dustproof door 32 inward, causing it to overcome the torque of the internal spring and rotate around the pivot to open, exposing the rear interface. After connection, the dustproof door remains closed under the restoring force of the spring. When the device plug is unplugged, the dustproof door, no longer obstructed by external force, immediately rotates and closes automatically under the drive of the spring, tightly covering the opening of the interface window 31 and effectively preventing dust from entering the chassis. The handle 33 located on the front side of the front panel 3 bears the main pulling force when moving the entire machine, allowing the user to lift and move the chassis safely and effortlessly. The power button receives the user's press operation and sends a start signal to the motherboard through internal circuitry to wake up the computer system. The adjacent status indicator light receives the motherboard's level signal in real time and clearly indicates the system's running, hibernation, or fault status to the user through different colors or flashing patterns of light.

[0035] In some examples, the keyboard tray 4 further includes a tray 41 and a folding frame 42. One end of the folding frame 42 is detachably fixed to a pre-set fixing hole on the bottom or side of the base box 1 by bolts, and the other end is connected to the tray 41 by bolts. The pivot of the folding frame 42 is provided with an adjustable damping bolt / hinge, which allows the keyboard tray 4 to be extended, folded, and its angle adjusted and positioned.

[0036] It should be noted that, depending on the user's needs, one end of the folding frame 42 can be bolted to the preset fixing holes on the bottom or side of the base box 1. When it needs to be unfolded, the user pulls the tray 41 outward, and the folding frame 42 unfolds accordingly. At this time, the appropriate frictional resistance can be set by adjusting the adjustable bolt at the pivot, so that the tray 41 can be stably maintained at the required extension length and tilt angle, providing stable support for the keyboard and mouse. After use, push the tray 41 to completely fold the tray 41 and the folding frame 42 together, close to the bottom or side of the host, greatly reducing the space occupied. In this folded state, the bolts can still provide sufficient holding force to prevent the tray 41 from accidentally unfolding due to gravity or vibration, ensuring the integrity of the device during transportation.

[0037] In some examples, the self-closing dustproof door 32 can be further designed as a two-piece structure that opens vertically or horizontally. The two-piece self-closing dustproof door 32 allows the upper / left door piece to open by rotating upwards / leftwards around the upper / left pivot axis, and the lower / right door piece to open by rotating downwards / rightwards around the lower / right pivot axis. The two door pieces move in opposite directions against the torque of their respective springs, creating sufficient insertion space. The two-piece self-closing dustproof door 32 achieves superior functionality and reliability within a limited space: its double-opening design reduces the required rotation radius and swing space for each door piece, thus providing more space for frequently inserted devices such as USB flash drives and wireless receivers. This effectively avoids the problem of devices obstructing the door from closing or being damaged by pressure, significantly improving compatibility and practicality.

[0038] The specific installation process is as follows: First, connect the desktop computer motherboard, power supply, and graphics card that conform to the ATX / BTX / ITX / RTX specifications. Figure 5As shown, the motherboard is installed inside chassis 1. The motherboard I / O shield is mounted on the corresponding notch of the front I / O shield 11, and the motherboard is secured with screws using the copper standoffs on chassis 1. The power supply is installed on the left rear side with the power cable connector facing left, and is secured with the included screws. The graphics card is installed sideways on the right side of chassis 1 with the cooling fan facing down, and is aligned with the front I / O shield 11 and secured with screws. The graphics card cooling fan draws in cool air through the air intake at the bottom of chassis 1. Since the graphics card is sideways after being secured, the gold fingers of the graphics card are connected to the motherboard's PCIe 16X connector via the included PCIe 16X extension cable. The slot is then connected to the motherboard network port 12 and the graphics card HDMI port 13 extension cable, respectively. The speaker module is located inside the bottom box 1 and fixed to the front panel 11. The speaker module cable is then plugged into the front headphone jack and USB jack on the motherboard (if using a speaker module with an integrated USB sound card, only the USB jack needs to be connected). Since the installation of other internal components such as CPU cooler, memory, hard drive and so on is exactly the same as that of ordinary cases, the installation description is omitted.

[0039] After the accessories are installed, the front panel 3 is combined with the base box 1. The power-on cable on the front panel 3 is connected to the motherboard opening pins. The handle 33 is fixed to the front panel 3 with bolts. After being combined with the base box 1, the front panel 3 has two interface windows 31 that correspond to the motherboard interface and graphics card interface positions, respectively. The semi-transparent dustproof door on the upper inner side of the interface window 31 is installed with a hinge and spring. It can be easily pushed open with a finger to expose the motherboard interface and graphics card interface. The distance from the interface window 31 to the motherboard interface and graphics card interface has been precisely calculated so that the opening and closing of the self-closing dustproof door does not affect the installation of USB flash drives, encryption modules, and wireless keyboard receivers. In one feasible design, a two-piece self-closing dustproof door that opens from the top and bottom can also be used to reduce the space occupied by the dustproof door inside the front panel 3.

[0040] Then assemble cover plate 2, align the monitor's DC power port and the mobile phone wireless charging module 10 with the openings on cover plate 2 and fix them with screws, and connect the connection cable of the DC power port and the connection cable of the wireless charging module to the 12V hard drive power supply cable of the power supply in the bottom box 1; then align the monitor's bracket 21 with the fixing holes on cover plate 2 and fix it with bolts, then combine the monitor with VASA holes (remove the original base support rod) with the rotatable VASA base with bolts, and use a hex wrench to adjust the damping at several pivots of the monitor's bracket 21 so that the monitor 21 can still be adjusted to various usage postures after bearing the weight of the monitor; put the assembled cover plate 2 on the bottom box 1 and fix it with bolts.

[0041] Finally, install the keyboard tray 4. The keyboard tray 4 can be used in two ways: lying flat on the desktop or standing upright on the desktop. The keyboard tray 4 is fixed to the bottom or side of the base box 1 with bolts. After being fixed to the base box 1, the keyboard tray 4 can hold the keyboard and mouse. The bolts at the hinge can be adjusted with a hex wrench as needed to make the keyboard tray 4 meet the user's needs.

[0042] After completing all the above installations, plug the power cord into the demo power supply 7, plug the network cable into the side adapter network port 12, connect the monitor to the monitor DC power supply port on the cover 2 using the DC connection cable, and connect the monitor to the side adapter HDMI signal port 13 using the HDMI cable. Users who prefer a zero-cable experience can choose wireless network, wireless HDMI transmission, or wireless keyboard and mouse. In this case, the device only has one power cord, which can completely solve the problem of messy cables on desktop computers.

[0043] In practical use, it can be like Figure 1 Use it by laying it flat on a table, or as... Figure 3 It can be used upright on a desktop (it comes with a stand 5 when upright), or like a traditional split desktop computer, with the main unit placed in the lower cabinet, the monitor on the desktop (with the original stand reinstalled), and the keyboard and mouse on the desktop. In this case, the stand 21 and keyboard tray 4 on the cover 2 can be folded and stored on top of the cover 2, or they can be removed. When relocation is required, it can be used as follows: Figure 2 Similarly, the monitor, keyboard, mouse and motherboard can be folded and stored together. After storage, adjust the screws on each hinge to make the storage mode stable and not easy to fall apart. When moving short distances, you can easily move it by holding the handle 33 with one hand. When moving long distances, you can pack the whole thing in the storage mode and then send it by express delivery. In the storage mode, the LCD screen is attached to the cover 2. It is not easy to be damaged during transportation without the original packaging box of the monitor.
