Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a graphics card mounting device and electronic device. Background Technology

[0002] Industrial control computers are widely used in the manufacturing industry, and different types of discrete graphics cards are often required for different application environments. However, the disassembly, assembly, and maintenance of discrete graphics cards are currently quite cumbersome, resulting in inconvenient operation, limited space, and long processing times. Utility Model Content

[0003] This application provides a graphics card mounting device and electronic equipment, which helps to solve the problem of cumbersome disassembly, assembly, and maintenance of discrete graphics cards. The various aspects involved in this application are described below.

[0004] In a first aspect, this application provides a graphics card fixing device, including: a fixing component and a graphics card bracket;

[0005] The fixing component includes a first locking mechanism, a sliding mechanism, and a thrust mechanism, wherein the first locking mechanism and the thrust mechanism are located at opposite ends of the sliding mechanism; the first locking mechanism includes at least one first latch, and a third latch is provided on the side of the first latch;

[0006] The sliding mechanism is provided with a sliding bracket, a first elastic element, a first hook, a second elastic element, and a second hook. The first hook is located at the first end of the sliding bracket, and the second hook is located at the opposite end of the first end. The first hook is used to engage with the first locking tongue. One end of the first elastic element is connected to the first end of the sliding bracket, and the other end of the first elastic element is connected to the housing of the first locking mechanism.

[0007] The thrust mechanism includes a frame, at least one second locking tongue, a third elastic element, and a push plate. The push plate is located on the side of the frame away from the sliding bracket and can slide relative to the frame. One end of the third elastic element is fixed to the push plate, and the other end of the third elastic element is directly opposite the second hook. The second hook is used to engage with the second locking tongue. One end of the second elastic element is connected to the opposite end of the first end of the sliding bracket, and the other end of the second elastic element is connected to the frame.

[0008] A graphics card bracket is provided for fixing and connecting a graphics card. One end of the graphics card bracket is provided with an operating component, and the other end of the graphics card bracket is provided with a third hook. The third hook is used to engage with a third locking tongue, and the operating component is movably connected to a second locking tongue.

[0009] When installing the graphics card bracket, the third hook engages with the third latch, causing the first hook to disengage from the first latch. The first elastic element drives the sliding bracket to move away from the first latch until the second hook engages with the second latch. When disassembling the graphics card bracket, the operating element drives the second hook to disengage from the second latch. The second and third elastic elements drive the sliding bracket to move away from the second latch until the third hook disengages from the third latch, and the first hook engages with the first latch.

[0010] Secondly, this application provides an electronic device, including: a motherboard and a base plate; the base plate is equipped with a graphics card mounting device as described in the first aspect, and when the graphics card bracket of the graphics card mounting device is installed, the graphics card on the graphics card bracket is connected to the motherboard.

[0011] In this embodiment, when installing a graphics card, the graphics card bracket is pushed in along a first direction. After installation, the first locking mechanism locks the third hook on the graphics card bracket, completing the graphics card installation. Because the first locking mechanism locks the third hook, the movement of the graphics card bracket in the first direction is restricted. The push plate and the graphics card bracket are subjected to pressure from the third elastic element, restricting the movement of the graphics card bracket in the second direction and the direction perpendicular to the second direction. The graphics card bracket is stably and reliably fixed in the installed state. When it is necessary to remove the graphics card, the operating component is triggered, causing the second locking tongue of the pushing mechanism to unlock the second hook, releasing the third elastic element. The second and third elastic elements release energy to drive the sliding bracket to move along the first direction, driving the third locking tongue to release the third hook. Under the action of the third elastic element and the push plate, the graphics card bracket is pushed outward. This separates the graphics card bracket from the gold finger socket on the motherboard, completing the removal of the graphics card. In this embodiment, graphics card removal and installation only need to be performed on the outside of the chassis, without disassembling the chassis cover, I / O board, or other components. It is not limited by the internal space of the chassis, making the operation convenient, reliable, and time-saving. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The same or similar reference numerals are used in the drawings to represent the same or similar modules. It should be understood that the drawings are merely illustrative, and the scope of protection of this application is not limited thereto.

[0025] First, the application scenarios involved in the embodiments of this application will be introduced.

[0026] Currently, some industrial control computers integrate the graphics card onto the motherboard, while others use a dedicated graphics card module plugged into the motherboard. For example... Figure 1 As shown in (a), discrete graphics card modules are typically fixed to the computer case using screws. Figure 1 As shown in (b), when removing the graphics card, you need to remove the top cover and other components such as the I / O board before you can loosen the graphics card mounting screws and remove the graphics card. The higher the configuration of the case, the more parts need to be removed.

[0027] Industrial PCs are widely used in the manufacturing industry, and different types of discrete graphics cards are often required for different application environments. Replacing the discrete graphics card in an industrial PC requires removing the top cover and disassembling some components for maintenance, which is cumbersome and inconvenient for on-site maintenance. Furthermore, maintenance is significantly affected by space constraints; if the entire machine is installed in a rack, operating space will be limited, and it may be necessary to remove the entire machine.

[0028] It is evident that the disassembly, assembly, and maintenance of discrete graphics cards are currently quite cumbersome, with issues such as inconvenience in operation, limited space, and long processing time.

[0029] Therefore, it is necessary to design a technical solution that facilitates the installation and removal of graphics cards.

[0030] Based on this, this application proposes a graphics card fixing device. The following is in conjunction with... Figure 2 , Figure 3 The graphics card fixing device according to the embodiments of this application will be described in detail. For example... Figure 2 , Figure 3 As shown, the graphics card mounting device 200 may include: a graphics card bracket 212 and a mounting component 220.

[0031] The fixing component 220 may be provided with a first locking mechanism 230, a sliding mechanism 240, and a thrust mechanism 250. The first locking mechanism 230 and the thrust mechanism 250 are respectively located at opposite ends of the sliding mechanism 240.

[0032] Specifically, such as Figure 5 As shown, the first locking mechanism 230 is provided with at least one first locking tongue 231, and a third locking tongue 232 is provided on the side of the first locking tongue 231.

[0033] In some embodiments, the first latch 231 may be a slider (sliding) type. In other embodiments, the first latch 231 may also be a swing type.

[0034] like Figure 2 , Figure 9 As shown, the sliding mechanism 240 is provided with a first guide rail 241 and a sliding bracket 242 that slides along the first guide rail 241. A first hook 243 and a first elastic element 244 are provided at the first end of the sliding bracket 242, and a second hook 245 and a second elastic element 246 are provided at the opposite end of the first end of the sliding bracket 242. Alternatively, the first hook 243 and the second hook 245 are located at opposite ends of the sliding bracket 242. The first hook 243 is used to engage with the first locking tongue 231. In this embodiment, the first hook 243 and the second hook 245 refer to push blocks provided with hooks. For example, the first hook 243 can be a hollow structure formed by welding multiple side rods.

[0035] In some embodiments, one end of the first elastic member 244 is connected to the first end of the sliding bracket 242, and the other end of the first elastic member 244 is connected to the housing 234 of the first locking mechanism 230.

[0036] In some embodiments, the housing 234 of the first locking mechanism 230 is provided with a third hole, through which the supports on both sides of the first hook 243 can pass. The first elastic member 244 is located between the supports on both sides of the first hook 243 and between the housing 234 and the first end of the sliding bracket 242, thus making the structure small and compact.

[0037] like Figure 6 As shown, the thrust mechanism 250 includes a frame 251, at least one second locking tongue 252, a third elastic element 254, and a push plate 255. The push plate 255 is located on the side of the frame 251 away from the sliding bracket 242 and can slide relative to the frame 251. One end of the third elastic element 254 is fixedly connected to the push plate 255, and the other end (floating end) of the third elastic element 254 is directly opposite the second hook 245. The second hook 245 is used to engage with the second locking tongue 252.

[0038] Optionally, the aforementioned elastic element can be a spring. For example, the first elastic element 244 and the second elastic element 246 can be springs.

[0039] In some embodiments, the second latch 252 may be a slider (sliding) type. In other embodiments, the second latch 252 may also be a swing type.

[0040] The first locking tongue 231 and the first hook 243 can form a locking mechanism (or latching mechanism); the second locking tongue 252 and the second hook 245 can form a locking mechanism. It can be seen that the first latching mechanism 230 and the thrust mechanism 250 are located at opposite ends of the sliding mechanism 240. The first end of the sliding bracket 242 is close to the first latching mechanism 230. For ease of explanation, the first end of the sliding bracket 242 can be called the inner end (inner end), and the opposite end can be called the outer end. The first direction is the direction from the thrust mechanism 250 to the first latching mechanism 230, or in other words, the direction from the outside to the inside. The second direction is the direction from the first latching mechanism 230 to the thrust mechanism 250, which is the opposite direction of the first direction.

[0041] In some embodiments, one end of the second elastic member 246 is connected to the opposite end of the first end of the sliding bracket 242, and the other end of the second elastic member 246 is connected to the frame 251 of the thrust mechanism 250. In some embodiments, the frame 251 is provided with a fourth hole, through which the supports on both sides of the second hook 245 can pass. The second elastic member 246 is located between the supports on both sides of the second hook 245, and between the frame 251 and the sliding bracket 242.

[0042] like Figure 8 As shown, a first hole 257 is provided on the side of the frame 251 away from the thrust mechanism 250, and the floating end of the third elastic member 254 can pass through the first hole 257 of the frame 251 to abut against the end face of the second hook 245.

[0043] like Figure 4 As shown, one end of the graphics card bracket 212 is provided with a third hook 213, and the other end is provided with an operating member 215. The graphics card bracket 212 is used to fix the graphics card 211, for example, the graphics card 211 can be fixed to the graphics card bracket 212 with screws. The graphics card 211 and the graphics card bracket 212 that fixes the graphics card 211 constitute the graphics card assembly 210. The third hook 213 is used to engage with the third locking tongue 232, and the third locking tongue 232 and the third hook 213 can form a locking mechanism. The operating member 215 is movably connected to the second locking tongue 252 and is used to drive the second locking tongue 252.

[0044] Optionally, the other end of the graphics card bracket 212 is provided with a guide hole 214, and the operating member 215 can pass through the guide hole 214. In some embodiments, the operating member 215 can be a button.

[0045] In some embodiments, the graphics card 211 can be fixed to the graphics card bracket 212 with screws. The rear of the graphics card 211 is usually gold fingers, which facilitates mating with the gold finger sockets on the motherboard to form a circuit connection.

[0046] like Figure 4 As shown, in some embodiments, the graphics card assembly 210 may further include a button bracket 216 and a seventh elastic element 217. For example, the button bracket 216 can be fixed to the graphics card bracket 212 by screws. The seventh elastic element 217 is used to reset the operating member 215. When the operating member 215 is pressed, the seventh elastic element 217 is in an energy-storing state; when the operating member 215 is not pressed, the seventh elastic element 217 releases energy, which can reset the operating member 215.

[0047] When installing the graphics card bracket 212, the third hook 213 engages with the third locking tongue 232, causing the first hook 243 to disengage from the first locking tongue 231. The first elastic element 244 drives the sliding bracket 242 to move away from the first locking tongue 231 until the second hook 245 engages with the second locking tongue 252. When removing the graphics card bracket 212, the operating element 215 drives the second hook 245 to disengage from the second locking tongue 252. The second elastic element 246 and the third elastic element 254 drive the sliding bracket 242 to move away from the second locking tongue 252 until the third hook 213 disengages from the third locking tongue 232 and the first hook 243 engages with the first locking tongue 231.

[0048] In this embodiment, when installing a graphics card, the graphics card bracket 212 is pushed in along the direction close to the first locking tongue 231. After installation, the first locking mechanism 230 locks the third hook 213 on the graphics card bracket 212, completing the graphics card installation. Because the first locking mechanism 230 locks the third hook 213, the movement of the graphics card bracket 212 is restricted in the first direction. The push plate and the graphics card bracket are pressured by the third elastic element 254, restricting the movement of the graphics card bracket 212 in the second direction and the direction perpendicular to the second direction. The graphics card bracket 212 is securely and reliably fixed in the installed state. When it is necessary to remove the graphics card, the triggering element 215 drives the second locking tongue 252 of the pushing mechanism 250 to unlock the second hook 245, releasing the third elastic element 254. The second elastic element 246 and the third elastic element 254 release energy to drive the sliding bracket 242 to move along the first direction, driving the third locking tongue 232 to release the third hook 213. Under the action of the third elastic element 254 and the push plate 255, the third elastic element 254 is pushed outward. To remove the graphics card, the graphics card assembly 210 is separated from the gold finger socket 281 on the motherboard 280. In this embodiment, the removal and installation of the graphics card can be performed only on the outside of the chassis, without the need to remove the chassis cover, I / O board, or other components. It is not limited by the internal space of the chassis, making the operation convenient, reliable, and time-saving.

[0049] In some implementations, such as Figure 6 As shown, the thrust mechanism 250 may also be provided with a spring column 253. The top of the inner cavity of the first end of the spring column 253 is connected to the other end of the third elastic member 254, and the first end of the spring column 253 can pass through the first hole 257 of the frame 251 and abut against the end face of the second hook 245. That is, the spring column 253 is floatingly disposed on one end of the third elastic member 254. The first end of the spring column 253 is provided with a boss 259, and the top surface of the boss 259 is used to abut against the second hook 245. The second locking tongue 252 is provided with a side baffle 258.

[0050] like Figure 8 As shown, a first hole 257 is provided on the side of the frame 251 away from the thrust mechanism 250, and the top of the elastic column 253 can pass through the first hole 257 of the frame 251 and abut against the end face of the second hook 245.

[0051] In the initial state where the graphics card bracket 212 is not installed with the fixing component 220, the side baffle 258 abuts against the bottom surface of the protrusion 259 of the elastic column 253 to restrict the elastic column 253 from moving in the first direction.

[0052] After the operating element 215 is triggered, it moves along the first direction to a first preset position, driving the second locking tongue 252 to release the second hook 245. The second elastic element 246 releases energy to drive the sliding bracket 242 to move along the first direction. When the operating element 215 moves along the first direction to a second preset position, the second locking tongue 252 drives the side baffle 258 to release the third elastic element 254. The third elastic element 254 releases energy to drive the third locking tongue 232 to release the third hook 213.

[0053] In this embodiment, one end of the elastic post 253 is provided with a boss 259, the top surface of which is used to abut against the second hook 245, and the second locking tongue 252 is provided with a side baffle 258. In the initial state, the side baffle 258 abuts against the bottom surface of the boss 259 of the elastic post 253, restricting the elastic post 253 from moving in the first direction. Since the elastic force of the third elastic element 254 cannot be released, during the process of the graphics card assembly 210 being installed into the fixing assembly 220 along the first direction, the third hook 213 drives the third locking tongue 232 and the first locking tongue 231 to release the first hook 243, and the first elastic element 244 releases energy to drive the sliding bracket 242 to move along the second direction. When the second elastic element 246 has accumulated energy, it can drive the second locking tongue 252 to lock the second hook 245. The initial state can be reliably entered to proceed to the next graphics card installation and removal cycle.

[0054] In some implementations, the thrust mechanism 250 may also be provided with a fourth elastic element 256, which is located between the frame 251 and the push plate 255. That is, a fourth elastic element 256 is provided between the frame 251 and the push plate 255.

[0055] When the graphics card bracket 212 is installed, the fourth elastic element 256 stores energy; when the graphics card bracket 212 is removed, the fourth elastic element 256 releases energy to drive the push plate 255 and the graphics card bracket 212 to move away from the first locking mechanism 230, that is, to drive the push plate 255 and the graphics card bracket 212 to move in the second direction.

[0056] A fourth elastic element 256 is provided between the frame 251 and the push plate 255. When the graphics card bracket 212 is disassembled, the fourth elastic element can drive the graphics card bracket 212 to pop out quickly in the second direction, making it easy for the user to remove.

[0057] The working process of the graphics card fixing device 200 according to an embodiment of this application is described below:

[0058] 1) Initial state. For example... Figure 3As shown in (a), in the initial state, before the graphics card assembly 210 (or graphics card bracket 212) is inserted into the fixing assembly 220 along the first direction, the third elastic element 254 and the fourth elastic element 256 are in a free state, and the third elastic element 254 is not in contact with the second hook 245. The first locking tongue 231 locks the first hook 243, and the first elastic element 244 is in an energy-storing state. The second locking tongue 252 is disengaged from the second hook 245, and the second elastic element 246 is in a energy-releasing state.

[0059] 2) Install the graphics card. For example... Figure 3 As shown in (b), during the process of the graphics card assembly 210 being installed into the fixing assembly 220 along the first direction, the third elastic element 254 and the fourth elastic element 256 accumulate energy, the graphics card bracket 212 abuts against the push plate 255, and the gold fingers of the graphics card 211 are connected to the gold finger socket 281 of the motherboard 280. The third hook 213 drives the first locking tongue 231 to release the first hook 243, the third locking tongue 232 locks the third hook 213, the first elastic element 244 releases energy to drive the sliding bracket 242 to move along the second direction, causing the second elastic element 246 to accumulate energy, the second locking tongue 252 locks the second hook 245, and the graphics card assembly 210 is in a locked state.

[0060] As can be seen, the displacements of the first hook 243 and the second hook 245 are the same, as are the displacements of the first elastic element 244 and the second elastic element 246. In some implementations, the Poisson coefficient of the first elastic element 244 is greater than that of the second elastic element 246. In this way, the first elastic element 244 releases energy to drive the sliding bracket 242 to move along the second direction, and the second elastic element 246, in a state of energy storage, can drive the second locking tongue 252 to lock the second hook 245.

[0061] 3) Unlock the graphics card. For example... Figure 3 As shown in (c), in response to a trigger operation, the operating element 215 drives the second locking tongue 252 to release the second hook 245, and the second locking tongue 252 releases the third elastic element 254. The second elastic element 246 and the third elastic element 254 release energy to drive the sliding bracket 242 to move in the first direction, causing the first elastic element 244 to accumulate energy, driving the third locking tongue 232 to release the third hook 213, causing the first locking tongue 231 to lock the first hook 243, and the fourth elastic element 256 releases energy to drive the push plate 255 and the graphics card assembly 210 to move in the second direction.

[0062] In some implementations, the Poisson's coefficient of the first elastic element 244 is less than the sum of the Poisson's coefficients of the second elastic element 246 and the third elastic element 254. Thus, the second elastic element 246 and the third elastic element 254 release energy to drive the sliding bracket 242 to move along the first direction. With energy stored in the first elastic element 244, it can drive the first locking tongue 231 to lock the first hook body 243.

[0063] In this embodiment, when installing a graphics card, the graphics card assembly 210 is pushed inward (in the first direction) along the first guide rail 241. After installation, the first locking mechanism 230 locks the third hook 213 on the graphics card assembly 210, completing the graphics card installation. Because the first locking mechanism 230 locks the third hook 213, the movement of the graphics card assembly 210 in the first direction is restricted. The fourth elastic element 256 accumulates energy, and the push plate 255 and the graphics card assembly 210 are subjected to pressure from the fourth elastic element 256. The movement of the graphics card assembly 210 in the second direction and the direction perpendicular to the second direction is restricted, ensuring the graphics card assembly 210 is stably and reliably fixed in the installed state. When it is necessary to remove the graphics card, the triggering element 215 drives the second locking tongue 252 of the pushing mechanism 250 to unlock the second hook 245, releasing the third elastic element 254. The second elastic element 246 and the third elastic element 254 release energy to drive the sliding bracket 242 to move along the first direction, driving the third locking tongue 232 to release the third hook 213. Under the action of the fourth elastic element 256 and the push plate 255 of the thrust mechanism 250, the graphics card assembly 210 is pushed outward, separating the graphics card assembly 210 from the gold finger socket 281 on the motherboard 280, thereby completing the removal of the graphics card. In this embodiment, the removal and installation of the graphics card can be performed only on the outside of the chassis, without the need to remove the chassis cover, I / O board, or other components. It is not limited by the internal space of the chassis, making the operation convenient, reliable, and time-saving.

[0064] In some implementations, such as Figure 8 As shown, the thrust mechanism 250 is further provided with a first push rod 261, a fifth elastic element 262, and a sixth elastic element 263. The second locking tongue 252 is provided with a second hole 264, the axis of which is parallel to the first direction. The first push rod 261 passes through the guide hole of the frame 251 and through the second hole 264 of the second locking tongue 252. The fifth elastic element 262 is used to reset the first push rod 261 along the second direction. The sixth elastic element 263 is used to reset the second locking tongue 252. The first push rod 261 and the second locking tongue 252 are provided with a sliding engagement surface. The angle between the sliding engagement surface and the first direction is an acute angle.

[0065] For example, when the first push rod 261 is driven by the operating member 215, the fifth elastic member 262 is in an energy storage state; when the first push rod 261 is not driven by the operating member 215, the fifth elastic member 262 releases energy and can reset the first push rod 261.

[0066] If the operating element 215 is triggered and moves to a first preset position along the first direction, the operating element 215 drives the first push rod 261 to move the second locking tongue 252 a first distance along a third direction through the sliding engagement surface. The second locking tongue 252 releases the second hook 245, and the second elastic element 246 releases energy to drive the sliding bracket 242 to move along the first direction. If the operating element 215 moves to a second preset position along the first direction, the operating element 215 drives the first push rod 261 to move the second locking tongue 252 a second distance along a third direction through the sliding engagement surface. This causes the side baffle 258 to release the third elastic element 254, and the third elastic element 254 releases energy to drive the third locking tongue 232 to release the third hook 213. The third direction is perpendicular to the first direction and away from the elastic column 253. The first distance is less than the second distance.

[0067] In this embodiment, the sliding inclined surface structure between the first push rod 261 and the second locking tongue 252 allows the second locking tongue 252 to release the second hook 245 when it moves a first distance along a third direction, and to release the third elastic element 254 when it moves a second distance. This allows the second locking tongue 252 to successively release the second hook 245 (corresponding to the second elastic element 246) and the third elastic element, resulting in a simple, stable, and reliable structure.

[0068] In some implementations, such as Figure 6 , Figure 8 As shown, at least one first guide seat 267 is provided on the side of the frame 251 near the push plate 255, and at least one first guide rod 266 and a second guide seat 265 are provided on the side of the push plate 255. A spring column 253 is fitted into the inner cavity of the second guide seat 265. An outer retaining ring is provided at the end of the spring column 253 near the push plate 255, and an inner retaining ring is provided at the end of the inner cavity of the second guide seat 265 near the frame 251. This prevents the spring column 253 from slipping out of the inner cavity of the second guide seat 265. A third elastic element 254 is fitted inside the spring column 253 and the second guide seat 265, ensuring smooth reciprocating motion of the first spring column 253 along the first direction.

[0069] The first guide rod 266 is fitted into the inner cavity of the first guide seat 267. An outer retaining ring is provided at the end of the first guide rod 266 near the frame 251, and an inner retaining ring is provided at the end of the inner cavity of the first guide seat 267 near the push plate 255. A fourth elastic element is fitted inside the first guide rod 266 and the first guide seat 267. This prevents the first guide rod 266 from slipping out of the inner cavity of the first guide seat 267, ensuring smooth guidance. The arrangement of the first guide rod 266 and the second guide seat allows the push plate 255 to run smoothly as it approaches or moves away from the frame 251.

[0070] The fixed component in its initial state, such as Figure 7 (a) Figure 8 As shown, the third elastic element 254 and the fourth elastic element 256 release energy, i.e., are in a free state. The top surface of the boss 259 of the third elastic element 254 does not contact the second hook 245. The second locking tongue 252 is in a reset state under the action of the sixth elastic element 263. There is a gap between the side baffle 258 connected to the second locking tongue 252 and the bottom surface of the boss 259 of the elastic column 253. In this way, when the push plate 255 is pushed inward by an external force, the side baffle 258 can restrict the movement of the elastic column 253 in the first direction. This is to prevent the first elastic element 244 from releasing energy and failing to compress the second elastic element 246 during the installation of the graphics card assembly 210, thereby causing the second locking tongue 252 to release the second hook 245.

[0071] In some implementations, the aforementioned at least one first locking tongue 231 can be two first locking tongues 231, with the two first locking tongues 231 located on both sides of the centerline of the sliding bracket 242. The at least one second locking tongue 252 can be two second locking tongues 252, with the two second locking tongues 252 located on both sides of the centerline of the sliding bracket 242.

[0072] In some implementations, the two first locking tongues 231 are symmetrically distributed about the centerline of the sliding bracket 242, and the first hook 243 is an axisymmetric structure, meaning it can be symmetrical about the centerline of the sliding bracket 242. The two second locking tongues 252 are also symmetrically distributed about the centerline of the sliding bracket 242, and the second hook 245 is an axisymmetric structure, meaning it can be symmetrical about the centerline of the sliding bracket 242. The third hook 213 is also an axisymmetric structure, meaning it can be symmetrical about the centerline of the sliding bracket 242. The thrust mechanism 250 has two first push rods 261, each corresponding to one of the two second locking tongues 252. This ensures stable force distribution and high reliability.

[0073] In some implementations, there can be two operating elements 215, with the two operating elements 215 directly opposite the two first push rods 261. The graphics card bracket 212 is provided with at least one seventh elastic element 217, which is used to reset the operating elements 215. Pressing one operating element 215 (button) alone will not activate the mechanism; both operating elements 215 must be pressed simultaneously to have an effect, thereby preventing accidental activation.

[0074] In some implementations, the Poisson's coefficient of the first elastic element 244 is greater than that of the second elastic element 246, and the Poisson's coefficient of the first elastic element 244 is less than the sum of the Poisson's coefficients of the second elastic element 246 and the third elastic element 254. For example, under the same stroke, the maximum elastic force of the first elastic element 244 is 4 units of force, the maximum elastic force of the second elastic element 246 is 3 units of force, and the maximum elastic force of the third elastic element 254 in the elastic column 253 is 2 units of force.

[0075] In some implementations, the first locking tongue 231 has a first inclined surface, and the first hook body 243 has a second inclined surface. The first and second inclined surfaces form a sliding mating surface. The angle between the first inclined surface and the first direction is smaller than the angle between the second inclined surface and the first direction. Since the sliding mating surface is in line contact, it helps to reduce motion resistance. And / or, the second locking tongue 252 has a third inclined surface, and the second hook body 245 has a fourth inclined surface. The third and fourth inclined surfaces form a sliding mating surface. The angle between the third inclined surface and the first direction is smaller than the angle between the fourth inclined surface and the first direction. The sliding mating surface is in line contact, which helps to reduce motion resistance, reduce the force parameters and specifications of each elastic element, and contribute to the miniaturization of the overall structure.

[0076] The graphics card mounting device 200 of this application will be further described below in conjunction with some possible implementations of this application.

[0077] like Figure 5 As shown, the first locking mechanism 230 may include a housing 234, two first locking tongues 231, two second locking tongues 252, and two eighth elastic elements 233. The two first locking tongues 231 are located on both sides of the first hook body, or referred to as the left slider and the right slider. The graphics card assembly 210 has a third hook body 213 at its tail. The third hook body 213 has a hook feature and is caught by the left and right sliders after being pushed in, thereby fixing the graphics card assembly 210. The eighth elastic element 233 is used to reset the first locking tongues 231 (i.e., the second locking tongues 232). The working mechanism of the first locking mechanism 230 is explained below.

[0078] When the graphics card bracket 212 of the graphics card assembly 210 is inserted to a certain position, it pushes the two second locking tongues 252 and the first locking tongue 231 (left and right sliders) to move to both sides, triggering the first hook 243 (or locking push rod) to move in the second direction, pushing the sliding bracket 242 to move. During unlocking, the sliding bracket 242 pushes the first hook 243 along the first direction. When the first hook 243 reaches a certain position, it pushes the two first locking tongues 231 and the third locking tongue 232 (slider type) to move to both sides, thereby unlocking the third hook 213 on the graphics card bracket 212. Under the pushing force of the spring column 253 in the pushing mechanism 250, the graphics card assembly 210 is pushed out, thus completing the disassembly action.

[0079] like Figure 6 , Figure 8 As shown, in the thrust mechanism 250, a first guide seat 267 is provided on the side of the frame 251 near the push plate 255, and two first guide rods 266 and two second guide seats 265 are provided on one side of the push plate 255. The two first guide rods 266 and the two second guide seats 265 are respectively located on both sides of the first guide seat 267.

[0080] When the graphics card component 210 is in the installed state, the second guide seat 265 is compressed by the button bracket 216. Figure 6 At the indicated position, the spring (third elastic element 254) inside the elastic column 253 is compressed, and the springs (fourth elastic element 256) on both sides of the second guide seats 265 are also compressed. After the graphics card assembly 210 is installed, the second hook 245 is pushed in, the spring (second elastic element 246) inside the second hook 245 is compressed, and the second hook 245 is fixed by the left and right second locking tongues 252. Figure 6 The location shown.

[0081] The working mechanism of the thrust mechanism 250 will be explained in detail below, taking into account the initial state, the graphics card installation state, and the graphics card unlocking state.

[0082] 1) Initial state. For example... Figure 7 As shown in (a), before the graphics card assembly 210 is inserted, the second guide seat 265 is in a released state, the third elastic element 254 inside the elastic column 253 is in a free state, and the top surface of the protrusion 259 of the third elastic element 254 does not contact the second hook 245. The second locking tongue 252 is in a reset state under the action of the sixth elastic element 263. There is a gap between the side baffle 258 connected to the second locking tongue 252 and the bottom surface of the protrusion 259 of the elastic column 253. The two side baffles 258 can abut against the sides of the protrusion 259 on both sides, restricting the movement of the elastic column 253 in the first direction.

[0083] 2) Graphics card installation status. For example... Figure 7 As shown in (b), during the graphics card installation process, after the graphics card assembly 210 is inserted, the spring inside the second guide seat 265 is compressed under the push of the button bracket 216. The step of the boss 259 at the top of the elastic column 253 in the initial state is blocked by the left and right side baffles 258 and cannot move in the first direction. The spring (third elastic element 254) inside the elastic column 253 is also compressed. Under the elastic force of the spring (first elastic element 244) inside the first hook 243, the second hook 245 moves downward (in the second direction), causing the spring (second elastic element 246) inside the second hook 245 to be compressed.

[0084] 3) Graphics card unlock status, corresponding to the status after pressing the operating component 215. For example... Figure 6 The right side and Figure 7As shown in (c), when the left and right first push rods 261 are pushed in the first direction to the first preset position (e.g., half of the stroke), under the inclined surface cooperation between the first push rod 261 and the second locking tongue 252, the second locking tongue 252 is pulled apart by a first distance to both sides, and the second hook 245 is unlocked first, while the left and right side baffles 258 still abut against the bottom surface of the protrusion 259 of the elastic column 253. At this time, because the elastic force of the spring (first elastic element 244) on the first locking mechanism 230 is greater than the elastic force of the spring (second elastic element 246) on the second hook 245, the first hook 243 cannot be pushed. For example, the maximum elastic force of the first elastic element 244 is set to 4 units of force, the maximum elastic force of the second elastic element 246 is set to 3 units of force, and the maximum elastic force of the third elastic element 254 in the elastic column 253 is set to 2 units of force.

[0085] like Figure 7 As shown in (c), when the left and right first push rods 261 are pushed in the first direction to the second preset position (e.g., two-thirds of the stroke), the left and right side baffles 258 move outward a second distance under the action of the left and right second locking tongues 252. The left and right side baffles 258 no longer block the bottom surface of the protrusion 259 of the elastic column 253, and the elastic column 253 is unlocked. The spring force in the elastic column 253 and the spring force in the second hook 245 are superimposed, which can push the first hook 243 to move in the first direction. The first hook 243 pushes the first locking tongue 231 and the third locking tongue 232. After the third locking tongue 232 releases the third hook 213, the first locking tongue 231 locks the first hook 243 under the reset action of the eighth elastic element 233. The first distance is less than the second distance.

[0086] In this embodiment, operating only one operating element 215 cannot unlock the second hook 245 or move the sliding bracket. Both operating elements 215 need to be pressed simultaneously to unlock the second hook 245 and the elastic column 253. Therefore, accidental touch can be prevented and the graphics card can be prevented from being accidentally ejected.

[0087] In some implementations, the extension of the first push rod 261 in the second direction passes through a guide hole at the outer end of the graphics card bracket 212 to form an operating member 215. Alternatively, the operating member 215 can be an extension of the first push rod 261, and the operating member 215 and the first push rod 261 can be a single piece. This helps simplify the structural design of the graphics card assembly 210.

[0088] In some implementations, the graphics card bracket 212 is provided with a protrusion 218 that abuts against the graphics card 211.

[0089] Specifically, such as Figure 4 As shown, the graphics card bracket 212 is provided with a protrusion 218, which (protruding step-shaped) contacts the graphics card chip at the bottom of the graphics card 211, thus achieving the function of heat transfer.

[0090] In some implementations, such as Figure 9 As shown, in the sliding mechanism 240, the first guide rail 241 is provided with a first guide groove 247, and the sliding bracket 242 is provided with at least one second slide rail 248. The angle between the second slide rail 248 and the first direction is an acute angle. The sliding bracket 242 is a heat-conducting sliding bracket, and the heat-conducting sliding bracket is connected to the heat dissipation system 290 (e.g., thermal connection). The sliding mechanism 240 also includes:

[0091] A first heat-conducting block 270 is provided with a sliding groove 271. The first heat-conducting block 270 runs on the second slide rail 248 of the sliding bracket 242 through the sliding groove 271. At least one slider 272 is provided on the side of the first heat-conducting block 270, and the at least one slider 272 passes through the guide groove 247 of the first guide rail 241. During the movement of the sliding bracket 242 along the first direction, the first heat-conducting block 270 moves along the fourth direction. When the graphics card assembly 210 is installed in the preset position of the fixing assembly 220, the top surface of the first heat-conducting block 270 abuts against the bottom surface of the graphics card bracket 212. During the movement of the sliding bracket 242 along the second direction, the first heat-conducting block 270 moves in the opposite direction of the fourth direction, which is perpendicular to the first direction. For example, the first direction is horizontal, and the fourth direction can be vertical. The first heat-conducting block 270 can be called a lifting heat-conducting block.

[0092] The thermally conductive sliding bracket can be an integral structure or a split structure.

[0093] Optionally, the thermally conductive sliding support is a split structure. For example... Figure 9 As shown, the sliding mechanism 240 may further include a second heat-conducting block 249. The second heat-conducting block 249 is fixedly disposed on the sliding bracket 242, together forming a heat-conducting sliding bracket. A second slide rail 248 may be disposed on the second heat-conducting block 249 fixed on the sliding bracket 242. The second heat-conducting block 249 is thermally connected to the heat dissipation system 290. If the first direction is horizontal, the second heat-conducting block 249 may be referred to as a horizontal heat-conducting block.

[0094] The sliding bracket 242 has arc-shaped guide portions on both sides, allowing it to slide back and forth along a first direction within the open guide grooves of the two first guide rails 241. The second heat-conducting block 249 can be fixed to the sliding bracket 242 with screws, and slides back and forth along the first direction together under the constraint of the sliding bracket 242. The first guide groove 247 extends along a fourth direction. The bottom of the first heat-conducting block 270 is an inclined surface, which fits against the top surface of the second heat-conducting block 249. The first heat-conducting block 270, constrained by the first guide grooves 247 of the left and right first guide rails 241, can only move up and down.

[0095] The working mechanism of the thermally conductive sliding bracket will be explained in detail below.

[0096] like Figure 10 As shown in (a), after the graphics card is installed, the sliding bracket 242 moves in the first direction under the push of the second hook 245, pushing the first heat-conducting block 270 upward to fit against the graphics card mounting bracket 212, thereby achieving the heat transfer function. Figure 10 As shown in (b), when the graphics card is unlocked, the sliding bracket 242 moves in the second direction, causing the first heat-conducting block 270 to descend, thereby separating the first heat-conducting block 270 from the graphics card bracket 212. The first heat-conducting block 270 and the second heat-conducting block 249 are designed with mutually cooperating inclined surfaces and a guiding arc-shaped rail, which may also be referred to as a third rail. In some embodiments, thermal grease may be filled between the contact surfaces of the first heat-conducting block 270 and the second heat-conducting block 249 to aid in heat conduction and lubrication.

[0097] In this embodiment, heatsinks and thermal greases with different thermal conductivity can be replaced to meet different heat dissipation needs, achieving good heat dissipation. Furthermore, the lifting mechanism of the first heatsink 270 adopts a modular design. In scenarios without graphics card heat dissipation requirements, the separate lifting and horizontal heatsinks (i.e., the first heatsink 270 and the second heatsink 249) can be removed, allowing the entire graphics card replacement device to still function normally, demonstrating good adaptability. While enabling quick graphics card removal, it also meets the heat dissipation requirements of high-power graphics cards, facilitating future maintenance and upgrades.
