Description

Technical Field

[0001] The present application relates to the technical field of computer motherboard hardware, and in particular to a motherboard structure and a host computer. Background Art

[0002] Typically, a PCIE (Peripheral Component Interconnect Express) graphics card slot is fixed vertically on the front of the motherboard. The graphics card is inserted vertically into the PCIE slot from the front of the motherboard and locks with the PCIE slot's latch to connect to the motherboard. Therefore, when removing the graphics card, you must first release the latch from the graphics card before you can pull it out.

[0003] However, when the motherboard, graphics card, CPU, radiator and other components in the chassis are arranged very compactly, it may be difficult to turn the lock to unlock the graphics card, which results in inconvenient and low disassembly efficiency of the graphics card. Utility Model Content

[0004] Based on this, it is necessary to address the above problems and provide a motherboard structure and a host that can easily disassemble the graphics card to improve the efficiency of graphics card disassembly.

[0005] The technical solution is as follows:

[0006] In a first aspect, the present application provides a mainboard structure, comprising:

[0007] a main board, the main board comprising a first side surface and a second side surface facing away from each other;

[0008] a slot assembly disposed on the first side surface, the slot assembly comprising a slot body and a locking member, the slot body being formed with a connection groove for inserting the insertion end of the graphics card, the locking member being rotatably connected to one end of the slot body, the locking member being configured to engage with the fastening member of the graphics card;

[0009] A quick-release assembly, the quick-release assembly comprising a quick-release housing, a transmission member, an unlocking member, a driving member and a first elastic member, the quick-release housing being arranged on the second side and forming a quick-release cavity, the transmission member being movably arranged in the quick-release cavity, the transmission member having a first end and a second end opposite to each other, the first end being drivingly connected to one end of the unlocking member, the other end of the unlocking member passing through the quick-release cavity and through the mainboard and then being drivingly connected to the locking member, the second end being drivingly connected to one end of the driving member, the other end of the driving member passing through the quick-release cavity and through the mainboard, the driving member being used to abut against the graphics card, one end of the first elastic member being connected to the unlocking member, and the other end being connected to the quick-release housing;

[0010] In which, the transmission member has a locking position in which the driving member abuts against the graphics card and an unlocking position in which the driving member is separated from the graphics card. In the locking position, the unlocking member can be driven by the transmission member to drive the locking member to rotate relative to the slot body to engage the fastening member; in the unlocking position, the unlocking member can be driven by the first elastic member to drive the locking member to rotate relative to the slot body to release the lock of the fastening member.

[0011] In the aforementioned host structure, the slot body is provided with a connection slot for inserting a graphics card. During insertion of the graphics card into the connection slot, the graphics card abuts a driver, thereby driving the driver to move. The driver then drives the transmission member from an unlocked position to a locked position. The unlocking member, driven by the transmission member, then drives the locking member to rotate relative to the slot body to engage with the latching member of the graphics card, thereby locking the slot assembly to the graphics card and completing the connection between the graphics card and the motherboard. When the graphics card is removed away from the motherboard, the force applied by the graphics card to the driver is reduced due to the separation of the driver and the graphics card. At this point, the unlocking member, driven by the first elastic member, drives the transmission member from the locked position to the unlocked position, and drives the latching member to rotate relative to the slot body to release the latching member. Therefore, to remove the graphics card, one only needs to pull the graphics card outward, reducing the force applied by the graphics card to the driver. This allows the quick release assembly to conveniently release the slot assembly from the graphics card, enabling rapid removal of the graphics card. Therefore, compared to conventional techniques, this motherboard structure allows for convenient graphics card removal via the quick release assembly, effectively improving graphics card removal efficiency.

[0035] See Figures 1 to 3 An embodiment of the present application provides a motherboard structure 100, comprising a motherboard 2, a slot assembly 1 and a quick-release assembly 3.

[0036] The motherboard 2 includes a first side surface 21 and a second side surface 22 facing each other. The slot assembly 1 is disposed on the first side surface 21. The slot assembly 1 includes a slot body 11 and a locking member 12. The slot body 11 is formed with a connecting groove for inserting the insertion end 201 of the graphics card 200. The locking member 12 is rotatably connected to one end of the slot body 11 and is used to engage with the fastening member 202 of the graphics card 200. The quick-release assembly 3 includes a quick-release housing 31, a transmission member 35, an unlocking member 33, a driving member 34, and a first elastic member 32. The quick-release housing 31 is disposed on the second side surface 22 and is formed with a quick-release cavity 31a. The transmission member 35 is movably disposed within the quick-release cavity 31a and has a first end 351a and a second end 351b opposite each other. The first end 351a is drivingly connected to one end of the unlocking member 33. The other end of the unlocking member 33 extends out of the quick-release cavity 31a, through the motherboard 2, and then is drivingly connected to the locking member 12. The second end 351b is drivingly connected to one end of the driving member 34. The other end of the driving member 34 extends out of the quick-release cavity 31a and through the motherboard 2. The driving member 34 is configured to abut the graphics card 200. One end of the first elastic member 32 is connected to the unlocking member 33, and the other end is connected to the quick-release housing 31. The transmission member 35 has a locked position in which the driving member 34 abuts the graphics card 200, and an unlocked position in which the driving member 34 is separated from the graphics card 200. In the locked position, the unlocking member 33, driven by the transmission member 35, can drive the locking member 12 to rotate relative to the slot 11 to engage the fastening member 202. In the unlocked position, the unlocking member 33 can be driven by the first elastic member 32 to drive the locking member 12 to rotate relative to the slot body 11 to release the locking of the fastening member 202 .

[0037] In the above-mentioned motherboard structure 100, the slot body 11 is provided with a connecting slot for inserting the graphics card 200. During the process of inserting the graphics card 200 into the connecting slot, the graphics card 200 can abut against the driving member 34 to drive the driving member 34 to move, and then the driving member 34 can drive the transmission member 35 to move from the unlocked position to the locked position, so that the unlocking member 33 can drive the locking member 12 to rotate relative to the slot body 11 under the drive of the transmission member 35 to lock with the fastening member 202 of the graphics card 200, thereby realizing the locking of the slot assembly 1 and the graphics card 200 and completing the connection between the graphics card 200 and the motherboard 2. When the graphics card 200 is removed from the motherboard 2, the force exerted by the graphics card 200 on the driver 34 is reduced due to the separation of the driver 34 from the motherboard 2. At this time, the unlocking member 33, driven by the first elastic member 32, can drive the transmission member 35 from the locked position to the unlocked position, and drive the locking member 12 to rotate relative to the slot body 11 to release the lock on the fastening member 202. Therefore, when removing the graphics card 200, it is only necessary to pull the graphics card 200 outward to reduce the force exerted by the graphics card 200 on the driver 34. That is, the quick release assembly 3 can conveniently release the slot assembly 1 from locking the graphics card 200, thereby achieving rapid removal of the graphics card 200. Therefore, compared with conventional technologies, the motherboard structure 100 can conveniently remove the graphics card 200 via the quick release assembly 3, effectively improving the removal efficiency of the graphics card 200.

[0038] Illustratively, the end of the driver 34 facing away from the transmission member 35 is located on the side of the slot 11 facing away from the locking member 12. This fully utilizes the space on the side of the motherboard 2 facing away from the slot 11 and the gap between the graphics card 200 and the motherboard 2, thereby reducing the volume of the motherboard structure 100. In other embodiments, the driver 34 may also be located on the side of the locking member 12 facing away from the slot 11.

[0039] Illustratively, when the graphics card 200 is inserted into the connection slot, the driving member 34 can abut and cooperate with the gold fingers in the graphics card 200 .

[0040] In one embodiment, Figure 1 and Figure 3 As shown, the quick-release housing 31 comprises an outer shell 311 and a bottom cover 312. The outer shell 311 is located on the second side surface 22. The bottom cover 312 is removably connected to the side of the outer shell 311 facing away from the mainboard 2, together forming a quick-release cavity 31a. The end of the unlocking member 33 facing away from the transmission member 35 passes through the outer shell 311 and the mainboard 2, and then is driven into connection with the locking member 12. The end of the driving member 34 facing away from the transmission member 35 passes through the outer shell 311 and the mainboard 2. This effectively ensures the reliable connection between the various components of the quick-release assembly 3. The removable connection between the bottom cover 312 and the outer shell 311 facilitates the convenient installation of the elastic member, driving member 34, transmission member 35, and unlocking member 33 in the quick-release cavity 31a, thereby improving the assembly efficiency of the quick-release assembly 3.

[0041] In one embodiment, combined Figure 1 and Figure 3 As shown, the transmission member 35 defines a first transmission hole 35a and a second transmission hole 35c extending along the relative directions of the first side surface 21 and the second side surface 22. A first inclined plate 35b is obliquely disposed on the first transmission hole 35a, one end of which is connected to the side wall of the first transmission hole 35a. A second inclined plate 35d is obliquely disposed on the second transmission hole 35c, one end of which is connected to the side wall of the second transmission hole 35c. The unlocking member 33, at one end near the transmission member 35, is movably disposed in the first transmission hole 35a. The unlocking member 33 has a first sliding surface 33a that slidably engages with the first inclined plate 35b. The driving member 34, at one end near the transmission member 35, is movably disposed in the second transmission hole 35c. The driving member 34 has a second sliding surface 34a that slidably engages with the second inclined plate 35d. In this way, during the process of inserting the graphics card 200 into the connecting slot, the driving member 34 can move toward the side away from the graphics card 200 under the drive of the graphics card 200, so that the second sliding surface 34a can slide along the second inclined plate 35d toward the side away from the motherboard 2, and then the transmission member 35 can move under the action of the friction between the second sliding surface 34a and the second inclined plate 35d. At this time, the unlocking member 33 can move toward the side close to the graphics card 200 under the action of the first inclined plate 35b and the first sliding surface 33a, so that the unlocking member 33 can push the locking member 12 to rotate relative to the slot body 11, wherein, when the graphics card 200 is plugged into place, the transmission member 35 moves to the locked position, and the locking member 12 can be rotated to the position of locking the fastening member 202 to achieve the locking of the fastening member 202. During the process of removing the graphics card 200, since the force applied by the graphics card 200 to the driving member 34 is reduced, the first elastic member 32 drives the unlocking member 33 to move to the side away from the graphics card 200, so that the transmission member 35 can overcome the force applied by the driving member 34 under the action of the unlocking member 33 and move to the unlocking position, and then the transmission member 35 can drive the driving member 34 to move to the side close to the graphics card 200 to reset. At this time, since the unlocking member 33 can drive the locking member 12 to rotate relative to the slot body 11 in the unlocking direction when it moves to the side away from the graphics card 200, when the unlocking member 33 drives the transmission member 35 to the unlocking position under the drive of the first elastic member 32, the locking member 12 can rotate to the unlocking position of the fastening member 202, thereby unlocking the graphics card 200, so that the graphics card 200 can be easily removed.

[0042] Furthermore, in one embodiment, the other end of the first inclined plate 35b extends toward the side closer to the second end 351b, and the other end of the second inclined plate 35d extends toward the side closer to the first end 351a. In this embodiment, when the graphics card 200 is inserted, the transmission member 35, under the action of the driving member 34, can move toward the side of the first end 351a away from the second end 351b, causing the unlocking member 33 to move toward the side closer to the graphics card 200, thereby enabling the locking member 12 to lock with the fastening member 202. When the graphics card 200 is removed, the unlocking member 33, under the action of the first elastic member 32, can drive the transmission member 35 toward the side of the second end 351b away from the first end 351a, thereby driving the driving member 34 to reset and ensuring that the unlocking member 33 can drive the locking member to rotate to release the fastening member 202.

[0043] In another embodiment, the other end of the first inclined plate 35b extends toward the side closer to the first end 351a, and the other end of the second inclined plate 35d extends toward the side closer to the second end 351b. Based on the analysis of the previous embodiment, in this embodiment, when the graphics card 200 is inserted, the transmission member 35, under the action of the driving member 34, can move toward the second end 351b away from the first end 351a, causing the unlocking member 33 to move toward the side closer to the graphics card 200, thereby enabling the locking member 12 to lock with the fastening member 202. When the graphics card 200 is removed, the unlocking member 33, under the action of the first elastic member 32, can also drive the transmission member 35 toward the side of the first end 351a away from the second end 351b, thereby driving the driving member 34 to reset and ensuring that the unlocking member 33 can drive the locking member to rotate to release the fastening member 202.

[0044] In other embodiments, the connection between the unlocking member 33, the transmission member 35, and the driving member 34 can also resemble a lever. Specifically, the transmission member 35 has a rotating shaft disposed between the unlocking member 33 and the driving member 34. The rotating shaft is rotatably connected to the quick-release housing 31. The end of the driving member 34 proximate to the transmission member 35 is connected to one end of the transmission member 35, and the end of the unlocking member 33 proximate to the transmission member 35 is connected to the other end of the transmission member 35. Furthermore, the driving member 34 and the unlocking member 33 are both disposed on the same side of the transmission member 35. In this manner, when the graphics card 200 drives the driving member 34 away from the graphics card 200, the transmission member 35 can leverage the unlocking member 33 to move toward the graphics card 200. When the unlocking member 33 moves away from the graphics card 200 under the action of the first elastic member 32, the transmission member 35 can reset the driving member 34.

[0045] In one embodiment, combined Figure 1 and Figure 3As shown, the quick-release assembly 3 includes a second elastic member 36 disposed within the quick-release cavity 31a. One end of the second elastic member 36 is connected to the transmission member 35, and the other end is connected to the quick-release housing 31. The second elastic member 36 is used to drive the transmission member 35 from a locked position to an unlocked position. Thus, when the graphics card 200 is removed, the transmission member 35 can be moved from the locked position to the unlocked position under the combined action of the second elastic member 36 and the unlocking member 33, ensuring that the quick-release assembly 3 can quickly and reliably release the locking member 12 from the fastening member 202, enabling rapid removal of the graphics card 200 and improving the efficiency of the graphics card 200 removal.

[0046] Optionally, the second elastic member 36 is a spring.

[0047] Further, if Figure 3 As shown, the transmission member 35 includes a plate body 351 and a shift plate 352. A first transmission hole 35a and a second transmission hole 35c are both defined in the plate body 351. The plate body 351 is disposed parallel to the second side surface 22. The shift plate 352 is disposed on a side of the plate body 351 that is closer to the second side surface 22 or on a side of the plate body 351 that is away from the second side surface 22. One end of the second elastic member 36 is connected to the shift plate 352, and the other end is connected to the quick-release housing 31. Specifically, when the other end of the first inclined plate 35b extends toward the side closer to the second end 351b and the other end of the second inclined plate 35d extends toward the side closer to the first end 351a, the second elastic member 36 is disposed on the side of the shift plate that is closer to the second end 351b. When the other end of the first inclined plate 35b extends toward the side closer to the first end 351a and the other end of the second inclined plate 35d extends toward the side closer to the second end 351b, the second elastic member 36 is disposed on the side of the shift plate that is closer to the first end 351a. In this way, when the transmission member 35 moves from the unlocked position to the locked position, the dial plate 352 can squeeze the second elastic member 36, so that when the graphics card 200 is moved out, the second elastic member 36 can drive the transmission member 35 to move from the locked position to the unlocked position.

[0048] Optional, such as Figure 3 As shown, the bottom cover 312 is arranged opposite to the plate body 351, and a top plate 312a is provided on the side of the bottom cover 312 facing the plate body 351. The second elastic member 36 is arranged between the plate body 351 and the bottom cover 312, and the end of the second elastic member 36 facing away from the dial plate 352 is connected to the top plate 312a.

[0049] Furthermore, in one embodiment, in combination Figure 1 and Figure 3As shown, the quick-release assembly 3 further includes a third elastic member 37, which is disposed in the quick-release cavity 31a. One end of the third elastic member 37 is connected to the driver 34, and the other end is connected to the quick-release housing 31. The third elastic member 37 is used to drive the driver 34 to move away from the transmission member 35. Thus, when the graphics card 200 is removed, the driver 34 can move upward under the action of the third elastic member 37 to quickly reset, thereby facilitating the transmission member 35 to move from the locked position to the unlocked position. This, in turn, allows the unlocking member 33 to quickly drive the locking member 12 to rotate, thereby releasing the lock on the graphics card 200 and enabling rapid removal of the graphics card 200. This further improves the efficiency and convenience of removing the graphics card 200.

[0050] Furthermore, in one embodiment, Figure 3 As shown, a positioning post 341 is protruding from one end of the driver 34, near the transmission member 35. The positioning post 341 extends in the relative direction between the first side surface 21 and the second side surface 22. The end of the third elastic member 37, near the driver 34, is sleeved around the outer periphery of the positioning post 341. In this way, the positioning post 341 can be used to control the position of the third elastic member 37, thereby ensuring the reliability of the connection between the third elastic member 37 and the driver 34. Furthermore, the positioning post 341 can also guide the compression and extension of the third elastic member 37, thereby facilitating the reliability of the motherboard structure 100.

[0051] Optionally, the third elastic member 37 is a spring.

[0052] Indicative, such as Figure 3 As shown, the third elastic member 37 is disposed between the driving member 34 and the bottom cover 312 . One end of the third elastic member 37 is connected to the bottom cover 312 , and the other end is inserted into the second transmission hole 35 c and sleeved on the outer periphery of the positioning column 341 .

[0053] In one embodiment, Figure 3As shown, the unlocking member 33 comprises a connected head 331 and a rod 332. The head 331 is movably disposed in the first transmission hole 35a, and a first sliding surface 33a is provided on the head 331. The end of the rod 332 facing away from the head 331 passes through the quick-release cavity 31a and through the motherboard 2, where it is drivenly connected to the locking member 12. The first elastic member 32 is sleeved around the rod 332, with one end of the first elastic member 32 connected to the head 331. Sleeving the first elastic member 32 around the outer periphery of the rod 332 helps ensure a secure connection between the first elastic member 32 and the unlocking member 33, while also simplifying the connection between the first elastic member 32 and the unlocking member 33. Furthermore, when removing the graphics card 200, the compressed first elastic member 32 effectively drives the unlocking member 33 toward the transmission member 35 under its elastic force, prompting the transmission member 35 to move to the unlocked position. This allows the unlocking member 33 to reliably rotate the locking member, thereby quickly removing the graphics card 200.

[0054] Illustratively, one end of the first elastic member 32 facing away from the head 331 is connected to the housing 311 .

[0055] Furthermore, in one embodiment, in combination Figure 3 and Figure 4 As shown, the locking member 12 includes a locking body 121 and a connecting portion 122. One end of the locking body 121 is rotatably connected to the slot body 11, and the other end of the locking body 121 is formed with a locking portion 121a for engaging with the fastening member 202. The connecting portion 122 is located on the side of the locking body 121 facing away from the slot body 11 and is connected to the end of the rod 332 facing away from the head 331. As such, a certain distance exists between the connection between the locking body 121 and the slot body 11 and the connection between the connecting portion 122 and the rod 332. This allows the movement of the rod 332 to drive the locking body 121 relative to the slot body 11 via the connecting portion 122, allowing the locking portion 121a to engage or disengage with the fastening member 202 of the graphics card 200. This allows for quick insertion and removal of the graphics card 200.

[0056] Furthermore, in one embodiment, in combination Figure 3 and Figure 4As shown, the connecting portion 122 includes two side panels 122a that are opposite to and spaced apart from each other, the end of the rod portion 332 that is away from the head portion 331 is arranged between the two side panels 122a, and connecting columns 333 are protruding from the opposite sides of the end of the rod portion 332 that is away from the head portion 331, and the connecting columns 333 are connected to the side panels 122a in a one-to-one correspondence. In this way, the end of the rod portion 332 away from the head portion 331 presents a "T" shape, which enables the unlocking member 33 to be reliably connected to the connecting portion 122 of the locking member 12 through the two connecting columns 333, so that when the transmission member 35 drives the unlocking member 33 to move, the unlocking member 33 can effectively drive the connecting portion 122 to move away from the motherboard, thereby driving the locking body 121 to rotate relative to the slot body 11 to engage the graphics card 200, thereby realizing the connection between the graphics card 200 and the motherboard 2. When the first elastic member 32 is compressed and drives the head portion 331 to move toward the side close to the transmission member 35, the rod portion 332 can pull the connecting portion 122 to move toward the side close to the motherboard, thereby causing the locking body 121 to rotate relative to the slot body 11 along the unlocking direction to unlock the graphics card 200, thereby realizing the removal of the graphics card 200.

[0057] An embodiment of the present application further provides a host, comprising a chassis, a graphics card 200 and the motherboard structure 100 of any of the above embodiments, wherein the chassis forms a chassis cavity, the graphics card 200 and the motherboard structure 100 are both installed in the chassis cavity, and the motherboard 2 is fixedly connected to the chassis, the insertion end 201 of the graphics card 200 is inserted into the connection slot, and the fastening part 202 of the graphics card 200 is engaged with the locking part 12.

[0058] In the above-mentioned host, the slot body 11 is provided with a connecting slot for inserting the graphics card 200. During the process of inserting the graphics card 200 into the connecting slot, the graphics card 200 can abut against the driving member 34 to drive the driving member 34 to move, and then the driving member 34 can drive the transmission member 35 to move from the unlocked position to the locked position, so that the unlocking member 33 can drive the locking member 12 to rotate relative to the slot body 11 under the drive of the transmission member 35 to lock with the fastening member 202 of the graphics card 200, thereby realizing the locking of the slot assembly 1 and the graphics card 200 and completing the connection between the graphics card 200 and the motherboard 2. When the graphics card 200 is removed from the side away from the motherboard 2, the force applied by the graphics card 200 to the driver 34 is reduced due to the separation of the driver 34 from the graphics card 200. At this time, the unlocking member 33, driven by the first elastic member 32, can drive the transmission member 35 from the locked position to the unlocked position, and drive the locking member 12 to rotate relative to the slot body 11 to release the lock on the fastening member 202. Therefore, when removing the graphics card 200, it is only necessary to pull the graphics card 200 outward to reduce the force applied by the graphics card 200 to the driver 34. That is, the quick release assembly 3 can conveniently release the slot assembly 1 from the graphics card 200, achieving rapid removal of the graphics card 200. Therefore, compared with conventional technologies, this host can conveniently remove the graphics card 200 via the quick release assembly 3, effectively improving the efficiency of removing the graphics card 200.
