Description

Technical Field

[0001] This utility model relates to the field of desktop computer technology, specifically to a horizontal connection structure between a graphics card and a motherboard. Background Technology

[0002] A horizontal connection structure between the graphics card and the motherboard, commonly known as "horizontal mounting" or "traditional mounting," is the most classic and widely used graphics card installation method since the birth of personal computers. Its core feature is that the gold fingers of the graphics card are perpendicularly aligned with the PCIe x16 slot of the motherboard, making the graphics card's PCB board parallel to the motherboard, thus allowing it to "lie" horizontally inside the computer case. This horizontal connection structure is a mature and reliable industry standard that has been proven through long-term practice. However, existing horizontal connection structures still have certain shortcomings. While the traditional horizontal connection between the graphics card and motherboard works well, high-end graphics cards are extremely heavy and are only secured to the motherboard by gold fingers and a backplate at the rear. Over time, the immense downward force can cause the graphics card PCB to bend and apply continuous stress to the motherboard's PCIe slot, potentially leading to slot solder joint problems, damage, or even motherboard deformation. Removing the graphics card requires unscrewing the backplate screws and forcefully pulling it out of the PCIe slot, often in a cramped space that could damage other hardware. Furthermore, the forceful insertion and removal can affect the lifespan of the interface, frequently causing inconvenience for users. Utility Model Content

[0003] The purpose of this invention is to provide a horizontal connection structure between the graphics card and the motherboard, addressing the issue raised in the background section where high-end graphics cards are extremely heavy and only secured to the motherboard via gold fingers and a backplate at the rear. Over time, the immense downward force can cause the graphics card PCB to bend, and it can also apply continuous stress to the motherboard's PCIe slot, potentially leading to slot solder joint defects, damage, or even motherboard deformation. Removing the graphics card requires unscrewing the backplate screws and forcefully pulling it out of the PCIe slot, often in a cramped space, increasing the risk of bumping into other hardware. Furthermore, forceful insertion and removal can affect the lifespan of the interface, a problem that frequently troubles users.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a horizontal connection structure between a graphics card and a motherboard, comprising a housing, a positioning mechanism, and a flexible connection mechanism. The housing is internally provided with the positioning mechanism and the flexible connection mechanism. The housing includes a chassis, a motherboard, a heat sink, a first connector, and a graphics card. The motherboard is fixedly installed inside the chassis by bolts. The heat sink is fixedly installed on the top surface of the chassis. The first connector is fixedly installed on the motherboard, and the graphics card is mounted on the motherboard. The positioning mechanism includes a slide rail, a slider, a slide rod, a fixed frame, a support wedge, a limit block, a spring, a rotating rod, a first connecting frame, a fixed wedge, and a connecting rod. Two sets of slide rails are fixedly installed on the inner bottom surface of the chassis. Two sets of sliders are slidably connected inside the slide rails, and a slide rod that is slidably connected to the sliders is fixedly installed inside the slide rails.

[0005] As a preferred embodiment of this utility model, a fixing frame is fixedly installed on the upper top surface of the slider, a support wedge is slidably connected to the fixing frame, and a limit block is fixedly installed on the support wedge.

[0006] As a preferred embodiment of this utility model, the limiting block is used in conjunction with the supporting wedge block, a spring is fixedly installed on the upper top surface of the slider, and the other end of the spring is fixedly installed on the lower bottom surface of the supporting wedge block.

[0007] As a preferred embodiment of this utility model, a rotating rod is fixedly installed on the supporting wedge block, a first connecting frame is rotatably connected to the rotating rod, a fixed wedge block is hinged to the upper part of the first connecting frame, and a connecting rod is fixedly installed on the upper top surface of the fixed wedge block.

[0008] As a preferred embodiment of this utility model, the connecting rod on the left is lower than the connecting rod on the right, and the overlapping part of the two connecting rods is fixed by a fixing bolt.

[0009] As a preferred embodiment of this utility model, the flexible connection mechanism includes a second connecting frame, a second connector, a flexible connection copper wire, and a receiver. The second connecting frame is fixedly installed on the right side of the graphics card, and the second connector is fixedly installed on the right side of the second connecting frame. The flexible connection copper wire is connected to the second connector, and the receiver is fixedly installed at the other end of the flexible connection copper wire, and the receiver is connected to the first connector.

[0010] Compared with existing technologies, the advantages of this invention are as follows: This horizontal connection structure between the graphics card and the motherboard, through an innovative wedge locking mechanism, provides rigid support from the sides and bottom of the graphics card, distributing the weight and deformation stress of the graphics card to the robust chassis base and positioning mechanism, rather than the motherboard's PCIe slot. This greatly protects the gold fingers of the motherboard and graphics card, extending the lifespan of the hardware. The mechanical clamping structure provides a fixing force far exceeding that of traditional graphics card brackets. Even during transportation or chassis movement, the graphics card will not shake or loosen, exhibiting extremely high stability, making it suitable for work scenarios requiring high reliability. Loosening the fixing bolts on the connecting rod releases the wedge locking force, allowing the graphics card to be easily removed. The entire maintenance process eliminates the need for laborious insertion and removal of the PCIe card slot, making the operation simpler and safer. Attached Figure Description

Two sets of sliders 202 are slidably connected inside the slide rails 201, and a slide rod 203 that is slidably connected to the sliders 202 is fixedly installed inside the slide rails 201.

[0015] A fixing frame 204 is fixedly installed on the top surface of the slider 202. A support wedge 205 is slidably connected to the fixing frame 204. A limit block 206 is fixedly installed on the support wedge 205.

[0016] The limiting block 206 is used in conjunction with the support wedge block 205. A spring 207 is fixedly installed on the upper top surface of the slider 202, and the other end of the spring 207 is fixedly installed on the lower bottom surface of the support wedge block 205.

[0017] A rotating rod 208 is fixedly installed on the support wedge 205. A first connecting frame 209 is rotatably connected to the rotating rod 208. A fixed wedge 210 is hinged to the upper part of the first connecting frame 209. A connecting rod 211 is fixedly installed on the top surface of the fixed wedge 210.

[0018] The left connecting rod 211 is lower than the right connecting rod 211, and the overlapping part of the two connecting rods 211 is fixed by a fixing bolt.

[0019] The flexible connection mechanism 3 includes a second connector 301, a second connector 302, a flexible copper wire 303, and a receiver 304. The second connector 301 is fixedly installed on the right side of the graphics card 105. The second connector 302 is fixedly installed on the right side of the second connector 301. The flexible copper wire 303 is connected to the second connector 302, and the receiver 304 is fixedly installed at the other end of the flexible copper wire 303. The receiver 304 is connected to the first connector 104.

[0020] Working principle: When using a flat connection structure between a graphics card and a motherboard, the motherboard 102 is first fixed to the chassis 101 with bolts, and the graphics card 105 is designed to be placed flat. The soft connection mechanism 3 is pre-connected: the second connector 302 on the graphics card 105 is connected to the first connector 104 on the motherboard 102 through the soft connection copper wire 303, i.e., a flexible PCB or high-speed cable, and the soft connection copper wire 303 passes through the first connection frame 209 to complete the transmission path of electrical signals. By sliding the slider 202 installed in the slide rail 201, the front and rear positions of the entire positioning mechanism 2 within the chassis 101 can be adjusted, thereby initially aligning it with the mounting position of the graphics card 105. The graphics card 105 is then placed on a support surface composed of two fixed wedges 210 and a support wedge 205. Due to the supporting action of the spring 207, the support wedge 205 can slide up and down within a certain range, thus adapting to possible unevenness or slight height differences at the bottom of the graphics card 105. After the graphics card 105 is placed in position, the two connecting rods 211 are tightened by tightening the fixing bolts connecting the left and right sides. The connecting rods 211 pull down the fixing wedge 210, and the fixing wedge 210 converts the downward locking force into the horizontal clamping force of the supporting wedge 205 through the first connecting bracket 209 and the rotating rod 208. The interaction of the wedge surfaces causes the supporting wedge 205 to be pushed inward while firmly supporting the graphics card 105, and together with the fixing wedge 210, firmly clamps and fixes the graphics card 105 from both sides and the bottom. The limiting block 206 is used to prevent the supporting wedge 205 from moving excessively, thereby completing a series of operations.
