Description

Technical Field

[0001] This invention relates to the field of graphics card technology, and more specifically, to a high-efficiency buffered fast horizontal mounting component and method for graphics cards. Background Technology

[0002] With the continuous improvement of graphics processing unit (GPU) performance, modern graphics cards are developing rapidly in terms of the number of computing units, power consumption and heat dissipation design. In order to meet the needs of high-performance computing and graphics rendering, the physical size and weight of graphics cards have also increased significantly. The length, thickness and weight of current mainstream high-end graphics cards have reached historical highs, with some models weighing more than 2 kilograms and exceeding 30 centimeters in length. This trend poses a serious challenge to the traditional way of installing graphics cards in computer cases.

[0003] Currently, most motherboards use a vertical slot design based on the PCI Express (PCIe) standard. The graphics card is vertically connected to the slot via gold fingers, and the motherboard PCB serves as the main support. However, as the weight of graphics cards continues to increase, the mechanical strength of the slot and the motherboard itself can no longer provide sufficient support. Especially during transportation or movement, the violent shaking or bending of the graphics card can easily lead to slot damage, poor contact of the gold fingers, or even deformation of the motherboard, which seriously affects the stability and lifespan of the system.

[0004] To address these issues, the industry has proposed several improvement solutions. A common approach is to add a graphics card support bracket or anti-sagging bracket inside the chassis to distribute the weight of the graphics card through auxiliary support structures. However, these solutions usually require operation within a small chassis, making installation and disassembly relatively inconvenient, and the adjustment accuracy and reliability of the support structures vary. In addition, some customized chassis attempt to rotate the motherboard 90 degrees to place the graphics card horizontally. While this can alleviate the impact of gravity on the slot to some extent, it does not fundamentally change the operating mode of requiring the graphics card to be plugged in inside the chassis, and is still limited by the internal space layout of the chassis, so the ease of installation and disassembly has not been substantially improved.

[0005] In summary, existing graphics card installation methods generally suffer from insufficient support, limited installation space, inconvenient disassembly and assembly, and poor buffering reliability when faced with the increasing size and weight of graphics cards. Therefore, there is an urgent need for a new type of graphics card installation component and method that can enable convenient and reliable plug-in operation of graphics cards outside the computer case, and provide effective buffering and support after installation, in order to adapt to the installation requirements of modern high-performance graphics cards and improve the overall stability and maintenance convenience of the system. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a high-efficiency buffered graphics card fast horizontal mounting component and a high-efficiency buffered graphics card fast horizontal mounting method, in view of the above-mentioned defects of the prior art.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] A high-efficiency buffered, quick horizontal mounting assembly for graphics cards is constructed, comprising a base plate and a cover that mates with the base plate; the lower surface of the cover is provided with a mounting slot for mounting the graphics card, and a buffer seat is provided within the mounting slot; the cover and the base plate are connected by multiple terminals and connectors; the lower surface of the base plate is provided with gold fingers that mate with the graphics card slot on the computer motherboard and connecting support feet for connecting to the computer; the connecting contacts on the gold fingers of the base plate are connected one-to-one with the connectors of the multiple connectors; the buffer seat is provided with an adapter slot for connecting the gold fingers of the graphics card, and the connecting contacts of the adapter slot are connected one-to-one with the connectors of the multiple terminals.

[0009] Furthermore, the buffer seat includes a mounting plate, one end of which is fixedly provided with the adapter slot; the mounting plate is provided with a left clamp and a right clamp for fixing the graphics card; the mounting plate is provided with multiple air holes and is connected to the inner top surface of the mounting slot through multiple rubber pillars; there are air passage gaps between the multiple rubber pillars, and the air holes are connected to adjacent air passage gaps.

[0010] Furthermore, a first rack and a second rack are slidably disposed on the upper surface of the mounting plate. The first rack and the second rack are parallel and are respectively connected to the left gripper and the right gripper. A gear is disposed between the first rack and the second rack, and the gear meshes with both the first rack and the second rack. The upper surface of the mounting plate is also provided with a first return spring for resetting the first rack and a second return spring for resetting the second rack.

[0011] Furthermore, both the left and right grippers are provided with longitudinal positioning holes; the base plate is provided with urethane posts corresponding to the two positioning holes respectively.

[0012] Furthermore, one end of the rubber column is provided with a stud and is threadedly connected to the inner top surface of the mounting groove, and the other end is provided with a screw hole, through which it is detachably connected to the mounting plate.

[0013] Furthermore, the upper surface of the cover is also fitted with an auxiliary fan for intake or exhaust of air through one or more air gaps.

[0014] Furthermore, a left buckle and a right buckle are provided on the side of the cover, and two slots corresponding to the left buckle and the right buckle are provided on the lower surface edge of the base plate.

[0015] Based on the same inventive concept, the present invention also provides a method for using the above-described installation components:

[0016] A method for rapid horizontal mounting of a graphics card with high-efficiency buffering, characterized by the following steps:

[0017] S1. Base plate installation: Separate the cover from the base plate, align the gold fingers on the lower surface of the base plate with the graphics card slot on the computer motherboard and insert and fix them, and at the same time use the connecting support feet on the lower surface of the base plate to assist in fixing it to the computer motherboard or chassis.

[0018] S2. Graphics card pre-installation: On the outside of the chassis, place the graphics card horizontally and insert it into the mounting slot on the lower surface of the cover, so that the gold fingers of the graphics card are aligned with the adapter slot on the buffer seat and inserted, and the graphics card is fixed by the clamping structure of the buffer seat.

[0019] S3. Overall docking: Move the cover with the graphics card installed to the top of the base plate that has been installed on the motherboard, align the multiple terminals on the cover with the multiple terminals on the base plate, and make vertical plug-in connections.

[0020] S4. Locking and Auxiliary Installation: The left and right latches on the side of the cover engage with the corresponding slots on the lower surface edge of the base plate to achieve final locking; if the component includes an auxiliary fan, its power is turned on.

[0021] Furthermore, in step S2, the step of fixing the graphics card through the clamping structure of the buffer seat is specifically as follows: pull either the left or right clamp outward, and make the two clamps move synchronously in opposite directions through gear and rack transmission to widen the gap. After placing the graphics card PCB board, release it. Under the action of the reset spring, the two clamps move synchronously inward to clamp the graphics card, and then push it in so that the gold fingers are fully inserted into the adapter card slot.

[0022] Furthermore, in step S3, during the process of connecting the cover to the base plate, the urethane posts on the base plate are simultaneously inserted into the positioning holes on the left and right grippers to achieve auxiliary positioning and buffering in the horizontal direction.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. Extremely convenient installation: The most complex steps of fixing and electrically connecting the graphics card, which require the most operating space, are completely transferred to the outside of the chassis. Users can easily operate in a spacious area such as a desktop. Finally, they only need to simply plug the cover module into the base plate, which greatly reduces the difficulty of operation and improves the efficiency of maintenance and upgrades.

[0025] 2. Revolutionary buffering and protection:

[0026] For graphics cards: The graphics card is "suspended" inside the cover by elastic rubber pillars, forming a floating buffer system that can effectively absorb vibrations and impacts from all directions; the flexible gripping of the claws and the positioning of the urethane rubber pillars further avoid the stress caused by rigid fixation.

[0027] For the motherboard: The base plate is firmly connected to the motherboard through gold fingers and multiple connecting support feet, distributing the entire weight and torque of the graphics card to multiple fixing points on the motherboard and the chassis, completely eliminating the lateral pull and bending moment of the graphics card on a single PCIe slot in the traditional method, and greatly protecting the motherboard.

[0028] 3. Excellent compatibility and heat dissipation: The clamp spacing is adjustable, making it compatible with graphics card PCBs of different widths; the three-dimensional airflow channel formed between the cover, mounting plate and rubber pillars, combined with the optional auxiliary fan, can effectively guide airflow to the back of the graphics card (PCB component side), assisting in heat dissipation, and is especially beneficial for reducing the temperature of the graphics card memory and power supply module.

[0029] 4. Stable and reliable connection: The large-area plug-in of the terminal block / socket and the mechanical locking of the buckle ensure the stability of the electrical and mechanical connection between the cover and the base plate, which is superior to the traditional PCIe extension cable connection method.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0037] A preferred embodiment of the present invention provides a high-efficiency buffer for a graphics card with rapid horizontal mounting, such as... Figures 1 to 3 As shown, it mainly consists of two major modules: the base plate 1 and the cover 2.

[0038] The base plate 1 is the part fixed to the motherboard 6; its lower surface is provided with standard (PCIe) gold fingers 11 for insertion into the graphics card slot 60 of the motherboard 6; next to the gold fingers 11, there are multiple connecting support feet 12, which can be fixed to other reserved holes on the motherboard 6 or the chassis by screws 61, so that the base plate 1 is firmly locked to the motherboard, making it a sturdy expansion base; the upper surface of the base plate 1 is provided with multiple sets of high-performance connectors 13 (such as high-speed board-to-board connectors); the lower edge of the base plate 1 is also provided with card slots and urethane posts 14.

[0039] The cover 2 is a movable graphics card support module; it has an internal mounting slot 22, in which a buffer seat 4 is suspended by multiple rubber pillars 5; the two ends of the rubber pillars 5 can be connected by threads for easy disassembly and replacement; the buffer seat 4 includes a mounting plate 42, one end of which is fixed with an adapter slot 41 for connecting the gold fingers of the graphics card 3; the mounting plate 42 has a vent 421; the mounting plate 42 has a set of synchronous clamping mechanism, including a left jaw 43, a right jaw 44, a first rack 45 and a second rack 46 connected to them respectively, a gear 47 meshing with both, and a first reset spring 48 and a second reset spring 49 providing reset force; the left and right jaws 43 and 44 have longitudinal positioning holes 441; an auxiliary fan 23 (connected to the power supply socket on the motherboard) can be embedded in the air passage gap between the rubber pillars 5 on the upper surface of the cover 2; the side of the cover 2 has a left buckle and a right buckle 25; the lower surface of the cover 2 has multiple sets of terminals 21 corresponding to the terminal block 13 on the base plate 1.

[0040] During installation, first install the base plate 1 onto the motherboard; then, outside the chassis, operate the cover 2: pull any one of the clamps (such as the right clamp 44), and under the transmission of gear 47, the left and right clamps 43 and 44 open synchronously in opposite directions; place the PCB board of the graphics card 3 into the cover, release the clamps, and under the action of the reset spring, the two clamps automatically clamp the sides of the graphics card 3; next, push the graphics card 3 into the adapter slot 41 until its gold fingers are fully inserted into the adapter slot 41; at this time, the graphics card 3 is firmly and flexibly fixed inside the cover 2.

[0041] Finally, align the assembled "cover 2 + graphics card 3" module with the base plate 1 on the motherboard and place it vertically. During this process, the wiring terminals 21 on the cover 2 are accurately inserted into the wiring sockets 13 on the base plate 1 to complete the electrical connection of all high-speed signals and power. At the same time, the urethane posts 14 on the base plate 1 are inserted into the positioning holes 441 on the clamps to provide horizontal auxiliary positioning and secondary buffering. Finally, snap the left and right clips on the side of the cover 2 into the slots on the base plate 1. A "click" sound indicates that the locking is complete. At this point, the entire graphics card is securely and elastically installed in place. The auxiliary fan 23 can be powered on as needed, and the airflow passes through the vents and air gaps to provide heat dissipation for the components on the back of the graphics card.

[0042] When removing the graphics card, simply open the clips and lift the cover 2 vertically upwards to remove the entire graphics card module. There is no need to touch the inside of the case, making the process safe and quick.

[0043] A method for quickly horizontally mounting a graphics card with efficient buffering, such as... Figure 4 As shown, it includes the following steps:

[0044] S1. Base plate installation: Separate the cover from the base plate, align the gold fingers on the lower surface of the base plate with the graphics card slot on the computer motherboard and insert and fix them, and at the same time use the connecting support feet on the lower surface of the base plate to assist in fixing it to the computer motherboard or chassis.

[0045] S2. Pre-installed graphics card: On the outside of the case, place the graphics card horizontally and insert it into the mounting slot on the lower surface of the cover, so that the gold fingers of the graphics card are aligned with the adapter slot on the buffer socket and plugged in. The graphics card is fixed by the clamping structure of the buffer socket.

[0046] S3. Overall Connection: Move the cover with the graphics card installed to the top of the base plate that has been installed on the motherboard, align the multiple terminals on the cover with the multiple terminals on the base plate, and make vertical plug-in connections.

[0047] S4. Locking and Auxiliary Installation: The final locking is achieved by engaging the left and right latches on the side of the cover with the corresponding slots on the lower surface edge of the base plate; if the component includes an auxiliary fan, its power is turned on.

[0048] 1. Extremely convenient installation: The most complex steps of fixing and electrically connecting the graphics card, which require the most operating space, are completely transferred to the outside of the chassis. Users can easily operate in a spacious area such as a desktop. Finally, they only need to simply plug the cover module into the base plate, which greatly reduces the difficulty of operation and improves the efficiency of maintenance and upgrades.

[0049] 2. Revolutionary buffering and protection:

[0050] For graphics cards: The graphics card is "suspended" inside the cover by elastic rubber pillars, forming a floating buffer system that can effectively absorb vibrations and impacts from all directions; the flexible gripping of the claws and the positioning of the urethane rubber pillars further avoid the stress caused by rigid fixation.

[0051] For the motherboard: The base plate is firmly connected to the motherboard through gold fingers and multiple connecting support feet, distributing the entire weight and torque of the graphics card to multiple fixing points on the motherboard and the chassis, completely eliminating the lateral pull and bending moment of the graphics card on a single PCIe slot in the traditional method, and greatly protecting the motherboard.

[0052] 3. Excellent compatibility and heat dissipation: The clamp spacing is adjustable, making it compatible with graphics card PCBs of different widths; the three-dimensional airflow channel formed between the cover, mounting plate and rubber pillars, combined with the optional auxiliary fan, can effectively guide airflow to the back of the graphics card (PCB component side), assisting in heat dissipation, and is especially beneficial for reducing the temperature of the graphics card memory and power supply module.

[0053] 4. Stable and reliable connection: The large-area plug-in of the terminal block / socket and the mechanical locking of the buckle ensure the stability of the electrical and mechanical connection between the cover and the base plate, which is superior to the traditional PCIe extension cable connection method.

[0054] Instead of following the traditional approach of "repairing within the existing chassis framework," this solution systematically restructures the entire graphics card "installation paradigm": transforming the installation process from "precise positioning, plugging and unplugging, and fixing operations within a narrow and unfriendly three-dimensional chassis" to "modular pre-installation on an open and user-friendly two-dimensional desktop, followed by a simple and clearly guided module docking," thus solving the core pain point of "inconvenient disassembly and assembly."

[0055] Meanwhile, compared to traditional solutions where the functions of connection, support, buffering, and heat dissipation are coupled and often conflict, this solution clearly decouples and optimizes these functions through a "base plate-cover" binary structure:

[0056] Base plate: Dedicated to reliable connection and power transmission, it bears the sole responsibility of establishing a stable electrical and mechanical connection with the motherboard, and distributes the weight of the graphics card to the motherboard / case through the support feet, fundamentally eliminating the bending moment of the graphics card on the PCIe slot.

[0057] Cover: It is dedicated to buffering, bearing and heat dissipation. It forms an active, multi-directional buffer bearing unit through the "rubber column suspension system" and "synchronous adaptive gripper". It not only supports the weight, but more importantly, it isolates and absorbs impact and vibration. At the same time, its structure naturally forms an auxiliary air duct.

[0058] Connection hub: The two are connected via a highly reliable board-to-board connector (terminal / socket), which replaces traditional extension cables and provides a more robust electrical connection with potentially better signal integrity.

[0059] This architecture, which separates connectivity from load sharing and is bridged by standardized high-speed interfaces, allows for the optimization of the design of each subsystem. It embodies systematic engineering thinking rather than piecemeal improvements.

[0060] Meanwhile, the innovative design of the cushioning seat:

[0061] Rubber column suspension system: It "suspends" the entire graphics card mounting plate in the cover through multiple flexible support points, forming a mass-spring-damping system that can effectively attenuate wide-band vibrations and has a buffering effect far exceeding that of point contact rigid support.

[0062] Integrated airflow channel: The "air gap" between the rubber pillars, combined with the "air holes" on the mounting plate and the auxiliary fan, creates an organized airflow channel that directly cools the back of the graphics card PCB (the area with dense heat-generating components).

[0063] Synchronous adaptive clamping mechanism:

[0064] Gear-rack synchronization mechanism: By driving two racks to move in opposite directions through a gear, the left and right grippers achieve absolutely synchronized and symmetrical movement. This not only makes the clamping force uniform and avoids the graphics card PCB from being twisted, but also allows for opening and closing with a single point of operation, providing an excellent user experience.

[0065] Secondary positioning and buffering with urethane columns: The positioning holes on the left and right grippers cooperate with the urethane columns on the base plate, which not only provides precise horizontal pre-positioning when large modules are docked to prevent misinsertion, but more importantly, as a high-damping elastic material, the urethane columns provide secondary horizontal constraint and buffering after being inserted into the positioning holes. Together with the vertical rubber column suspension system, it achieves an effect close to "omnidirectional buffering".

[0066] Maintainability and compatibility design:

[0067] The threaded connection of the rubber pillars makes it easy to replace rubber pillars of different hardness or height to accommodate graphics cards of different weights or adjust the buffering characteristics; the adaptive width adjustment of the grippers makes them compatible with graphics cards of different PCB widths, making them highly versatile.

[0068] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
