Summary of the Invention

[0003] This application provides a graphics card fixing device and an electronic device, which helps to solve the problem that the disassembly, installation and maintenance of independent graphics cards are relatively cumbersome. The following introduces each aspect involved in this application.

[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. The first locking mechanism and the thrust mechanism are respectively located at opposite ends of the sliding mechanism; the first locking mechanism includes at least one first locking tongue, and a third locking tongue is arranged on the side of the first locking tongue;

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

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

[0008] A graphics card bracket, which is used for fixedly connecting a graphics card. An operating member is arranged at one end of the graphics card bracket, and a third hook body is arranged at the other end of the graphics card bracket. The third hook body is used for engaging with the third locking tongue, and the operating member is movably connected to the second locking tongue;

[0009] When installing the graphics card bracket, the third hook body is engaged with the third locking tongue, so that the first hook body is disengaged from the first locking tongue. The first elastic member drives the sliding bracket to move away from the first locking tongue until the second hook body is latched with the second locking tongue. When disassembling the graphics card bracket, the operating member drives the second hook body to disengage from the second locking tongue. The second elastic member and the third elastic member drive the sliding bracket to move away from the second locking tongue until the third hook body is disengaged from the third locking tongue, and the first hook body is latched with the first locking tongue.

[0011] In the embodiment of the present application, when installing the graphics card, the graphics card bracket is pushed in along the first direction. After being installed in place, the first locking mechanism locks the third hook body on the graphics card bracket to complete the graphics card installation action. Since the first locking mechanism locks the third hook body, the movement of the graphics card bracket in the first direction is restricted. The push plate and the graphics card bracket are under the pressure of the third elastic member, and the movement of the graphics card bracket in the second direction and the direction perpendicular to the second direction is restricted. The graphics card bracket is fixed stably and reliably in the installed state. When it is necessary to disassemble the graphics card, the operating member is triggered to drive the second locking tongue of the thrust mechanism to unlock the second hook body, and the second locking tongue releases the third elastic member. The second elastic member and the third elastic member release energy to drive the sliding bracket to move along the first direction, and drive the third locking tongue to release the third hook body. Under the action of the third elastic member and the push plate, the graphics card bracket is pushed outwards. For example, the graphics card bracket is separated from the gold finger socket on the main board to complete the disassembly of the graphics card. In the embodiment of the present application, the disassembly and installation of the graphics card only need to be operated outside the chassis, without the need to disassemble components such as the chassis cover and the IO board, and are not restricted by the internal space of the chassis. The operation is convenient, reliable and time-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The same or similar reference numerals are used in the accompanying drawings to represent the same or similar modules. It should be understood that the accompanying drawings are only schematic, and the protection scope of the present application is not limited thereto.

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

[0026] Currently, in some industrial personal computers, the graphics card is integrated on the motherboard, and in some industrial personal computers, an independent graphics card module is inserted into the motherboard. As shown in (a) of Figure 1 , the independent graphics card module is generally fixed to the chassis with screws. As shown in (b) of Figure 1 , when disassembling the graphics card, it is necessary to remove the upper cover and disassemble components such as the IO board to loosen the graphics card fixing screws and remove the graphics card. The higher the chassis configuration, the more components need to be disassembled.

[0027] Industrial control computers are widely used in the manufacturing field. For different usage sites, different types of independent graphics cards often need to be matched. The replacement of the independent graphics card in an industrial control computer requires the upper cover to be removed and some components to be disassembled before maintenance and replacement, which is rather cumbersome and very inconvenient for on-site maintenance operations. Moreover, maintenance is greatly affected by space limitations. If the entire machine has been installed in a cabinet, the operating space will be limited, and it may be necessary to remove the entire body.

[0028] It can be seen that the disassembly, installation and maintenance of the current independent graphics card are rather cumbersome, and there are problems such as inconvenient operation, limited space and long time consumption.

[0029] Therefore, it is necessary to design a technical solution for convenient disassembly and installation of the graphics card.

[0030] Based on this, an embodiment of the present application proposes a graphics card fixing device. The following will be combined with Figure 2 、 Figure 3 to introduce the graphics card fixing device of the embodiment of the present application in detail. As Figure 2 、 Figure 3 shown, the graphics card fixing device 200 may include: a graphics card bracket 212 and a fixing 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, as Figure 5 shown, the first locking mechanism 230 is provided with at least one first locking tongue 231, and a third locking tongue 232 is arranged on the side surface of the first locking tongue 231.

[0033] In some embodiments, the first locking tongue 231 may be in the form of a slider (sliding). In other embodiments, the first locking tongue 231 may also be in the form of a swing.

[0034] As Figure 2 、 Figure 9 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 body 243 and a first elastic member 244 are arranged at the first end of the sliding bracket 242, and a second hook body 245 and a second elastic member 246 are arranged at the opposite end of the first end of the sliding bracket 242. Or rather, the first hook body 243 and the second hook body 245 are respectively located at both ends of the sliding bracket 242. The first hook body 243 is used to engage with the first locking tongue 231. In the embodiment of the present application, the first hook body 243 and the second hook body 245 refer to push blocks provided with hook bodies. For example, the first hook body 243 may be a hollow structure formed by welding a plurality of 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, a third hole portion is provided on the housing 234 of the first locking mechanism 230, and the struts on both sides of the first hook body 243 can pass through the third hole portion on the housing 234. The first elastic member 244 is located between the struts on both sides of the first hook body 243, and between the housing 234 and the first end of the sliding bracket 242, so that the structure is small and compact.

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

[0038] Optionally, the above-mentioned elastic member can be a spring. For example, the first elastic member 244 and the second elastic member 246 can be springs.

[0039] In some embodiments, the second locking tongue 252 can be in the form of a slider (sliding). In other embodiments, the second locking tongue 252 can also be in the form of a swing.

[0040] The first locking tongue 231 and the first hook body 243 can form a locking mechanism (or a locking mechanism); the second locking tongue 252 and the second hook body 245 can form a locking mechanism. It can be seen that the first locking mechanism 230 and the thrust mechanism 250 are respectively located at both ends of the sliding mechanism 240. The first end of the sliding bracket 242 is close to the first locking mechanism 230. For the convenience of description, the first end of the sliding bracket 242 can be called the inner end (inner end), and the opposite end of the first end can be called the outer end. The first direction is the direction in which the thrust mechanism 250 points to the first locking mechanism 230, or in other words, the first direction is the direction from the outside to the inside. The second direction is the direction in which the first locking mechanism points to the thrust mechanism 250, that 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 body 251 of the thrust mechanism 250. In some embodiments, the frame body 251 is provided with a fourth hole portion, and the struts on both sides of the second hook body 245 can pass through the fourth hole portion of the frame body 251. The second elastic member 246 is located between the struts on both sides of the second hook body 245, and between the frame body 251 and the sliding bracket 242.

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

[0043] As shown Figure 4 in the figure, a third hook body 213 is provided at one end of the graphics card bracket 212, and an operating member 215 is provided at the other end of the graphics card bracket 212. The graphics card bracket 212 is used for fixedly connecting the graphics card 211. For example, the graphics card 211 can be fixed to the graphics card bracket 212 by screws. The graphics card 211 and the graphics card bracket 212 for fixing the graphics card 211 form a graphics card assembly 210. The third hook body 213 is used for engaging with the third locking tongue 232, and the third locking tongue 232 and the third hook body 213 can form a locking mechanism. The operating member 215 is movably connected to the second locking tongue 252 and is used for driving the second locking tongue 252.

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

[0045] In some embodiments, the graphics card 211 can be fixed to the graphics card bracket 212 by screws. The tail of the graphics card 211 is usually a gold finger, which is convenient for plugging into the gold finger socket on the motherboard to form an electrical connection.

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

[0047] When installing the graphics card bracket 212, the third hook body 213 is engaged with the third locking tongue 232, so that the first hook body 243 is disengaged from the first locking tongue 231, and the first elastic member 244 drives the sliding bracket 242 to move in a direction away from the first locking tongue 231 until the second hook body 245 is engaged with the second locking tongue 252; when disassembling the graphics card bracket 212, the operating member 215 drives the second hook body 245 to disengage from the second locking tongue 252, and the second elastic member 246 and the third elastic member 254 drive the sliding bracket 242 to move in a direction away from the second locking tongue 252 until the third hook body 213 is disengaged from the third locking tongue 232, and the first hook body 243 is engaged with the first locking tongue 231.

[0048] In the embodiment of the present application, when installing the graphics card, the graphics card bracket 212 is pushed along the direction close to the first locking tongue 231. After being installed in place, the first locking mechanism 230 locks the third hook body 213 on the graphics card bracket 212, completing the installation action of the graphics card. Since the first locking mechanism 230 locks the third hook body 213, the movement of the graphics card bracket 212 is restricted in the first direction. The push plate and the graphics card bracket are under the pressure of the third elastic member 254, and the movement of the graphics card bracket 212 is restricted in the second direction and the vertical direction of the second direction. The graphics card bracket 212 is fixed stably and reliably in the installed state. When the graphics card needs to be removed, the operating member 215 is triggered to drive the second locking tongue 252 of the thrust mechanism 250 to unlock the second hook body 245, and the second locking tongue 252 releases the third elastic member 254. The second elastic member 246 and the third elastic member 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 body 213. Under the action of the third elastic member 254 and the push plate 255, the third elastic member 254 is pushed outwards. For example, the graphics card assembly 210 is separated from the gold finger socket 281 on the motherboard 280, completing the removal of the graphics card. In the embodiment of the present application, the removal and installation of the graphics card only need to be operated outside the chassis, without the need to remove components such as the chassis cover and the IO board, and are not restricted by the internal space of the chassis, with convenient, reliable, and time-saving operations.

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

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

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

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

[0053] In the embodiment of the present application, a boss 259 is provided at one end of the elastic column 253, and the top surface of the boss 259 is used to abut against the second hook body 245, and the second locking tongue 252 is provided with a side baffle 258. In the initial state of the fixing assembly 220, the side baffle 258 abuts against the bottom surface of the boss 259 of the elastic column 253, restricting the elastic column 253 from moving in the first direction. Since the elastic force of the third elastic member 254 cannot be released, when the graphics card assembly 210 is inserted into the fixing assembly 220 along the first direction, the third hook body 213 drives the third locking tongue 232 and the first locking tongue 231 to release the first hook body 243, and the first elastic member 244 releases energy to drive the sliding bracket 242 to move in the second direction. In a state where the second elastic member 246 stores energy, the second locking tongue 252 can be driven to lock the second hook body 245. It can reliably enter the initial state for the next graphics card installation and disassembly cycle.

[0054] In some implementation manners, the thrust mechanism 250 may further be provided with a fourth elastic member 256, and the fourth elastic member 256 is located between the frame body 251 and the push plate 255. That is, a fourth elastic member 256 is provided between the frame body 251 and the push plate 255.

[0055] When installing the graphics card bracket 212, the fourth elastic member 256 stores energy; when disassembling the graphics card bracket 212, the fourth elastic member 256 releases energy to drive the push plate 255 and the graphics card bracket 212 to move in a direction 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 member 256 is provided between the frame body 251 and the push plate 255. When disassembling the graphics card bracket 212, the fourth elastic member can drive the graphics card bracket 212 to quickly pop out in the second direction, facilitating the user to take it out.

[0057] The working process of the graphics card fixing device 200 in the embodiment of the present application will be described below:

[0058] 1) Initial state. As Figure 3As shown in (a) thereof, in the initial state of the fixing component, that is, before the graphics card component 210 (or the graphics card bracket 212) is inserted into the fixing component 220 along the first direction, the third elastic member 254 and the fourth elastic member 256 are in a free state, and the third elastic member 254 does not contact the second hook body 245. The first locking tongue 231 locks the first hook body 243, and the first elastic member 244 is in an energy storage state. The second locking tongue 252 is disengaged from the second hook body 245, and the second elastic member 246 is in an energy release state.

[0059] 2) Install the graphics card. As Figure 3 shown in (b) thereof, during the process of inserting the graphics card component 210 into the fixing component 220 along the first direction, the third elastic member 254 and the fourth elastic member 256 store 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 main board 280. The third hook body 213 drives the first locking tongue 231 to release the first hook body 243, the third locking tongue 232 locks the third hook body 213, the first elastic member 244 releases energy to drive the sliding bracket 242 to move along the second direction, so that the second elastic member 246 stores energy, the second locking tongue 252 locks the second hook body 245, and the graphics card component 210 is in a locked state.

[0060] It can be seen that the displacements of the first hook body 243 and the second hook body 245 are the same, and the displacements of the first elastic member 244 and the second elastic member 246 are the same. In some implementation manners, the Poisson's coefficient of the first elastic member 244 is greater than that of the second elastic member 246. In this way, when the first elastic member 244 releases energy to drive the sliding bracket 242 to move along the second direction, in the state where the second elastic member 246 stores energy, it can drive the second locking tongue 252 to lock the second hook body 245.

[0061] 3) Unlock the graphics card. As Figure 3 shown in (c) thereof, the operating member 215 drives the second locking tongue 252 to release the second hook body 245 and the second locking tongue 252 releases the third elastic member 254 in response to the triggering operation. The second elastic member 246 and the third elastic member 254 release energy to drive the sliding bracket 242 to move along the first direction, so that the first elastic member 244 stores energy, drives the third locking tongue 232 to release the third hook body 213, so that the first locking tongue 231 locks the first hook body 243, and the fourth elastic member 256 releases energy to drive the push plate 255 and the graphics card component 210 to move in the second direction.

[0062] In some implementation manners, the Poisson's coefficient of the first elastic member 244 is less than the sum of the Poisson's coefficients of the second elastic member 246 and the third elastic member 254. In this way, when the second elastic member 246 and the third elastic member 254 release energy to drive the sliding bracket 242 to move along the first direction, in the state where the first elastic member 244 stores energy, it can drive the first locking tongue 231 to lock the first hook body 243.

[0063] In the embodiment of the present application, when installing the graphics card, the graphics card assembly 210 is pushed inward (i.e., in the first direction) along the first guide rail 241. After being installed in place, the first locking mechanism 230 locks the third hook body 213 on the graphics card assembly 210, completing the graphics card installation operation. Since the first locking mechanism 230 locks the third hook body 213, the movement of the graphics card assembly 210 in the first direction is restricted, the fourth elastic member 256 accumulates energy, the push plate 255 and the graphics card assembly 210 are under the pressure of the fourth elastic member 256, and the movement of the graphics card assembly 210 in the second direction and the vertical direction of the second direction is restricted. The graphics card assembly 210 is fixed stably and reliably in the installed state. When the graphics card needs to be removed, the operating member 215 is triggered to drive the second locking tongue 252 of the thrust mechanism 250 to unlock the second hook body 245, and the second locking tongue 252 releases the third elastic member 254. The second elastic member 246 and the third elastic member 254 release energy to drive the sliding bracket 242 to move along the first direction, and drive the third locking tongue 232 to release the third hook body 213. Under the action of the fourth elastic member 256 and the push plate 255 of the thrust mechanism 250, the graphics card assembly 210 is pushed outwards, separating the graphics card assembly 210 from the gold finger socket 281 on the main board 280, thus completing the removal of the graphics card. In the embodiment of the present application, the removal and installation of the graphics card only need to be operated outside the chassis, without the need to remove components such as the chassis cover and the IO board, and are not restricted by the internal space of the chassis. The operation is convenient, reliable, and time-saving.

[0064] In some implementation manners, such as Figure 8 shown, the thrust mechanism 250 is further provided with a first push rod 261, a fifth elastic member 262, and a sixth elastic member 263. The second locking tongue 252 is provided with a second hole portion 264, and the axis line of the second hole portion 264 is parallel to the first direction. The first push rod 261 passes through the guiding hole of the frame body 251 and passes through the second hole portion 264 of the second locking tongue 252. The fifth elastic member 262 is used to reset the first push rod 261 along the second direction. The sixth elastic member 263 is used to reset the second locking tongue 252, and the first push rod 261 and the second locking tongue 252 are provided with a sliding joint surface. The included angle between the sliding joint 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 member 215 is triggered and moves in the first direction to the first preset position, the operating member 215 drives the first push rod 261 to move the second locking tongue 252 in the third direction by a first distance through the sliding joint surface. The second locking tongue 252 releases the second hook body 245, and the second elastic member 246 releases energy to drive the sliding bracket 242 to move in the first direction. If the operating member 215 moves in the first direction to the second preset position, the operating member 215 drives the first push rod 261 to move the second locking tongue 252 in the third direction by a second distance, driving the side baffle 258 to release the third elastic member 254. The third elastic member 254 releases energy to drive the third locking tongue 232 to release the third hook body 213. The third direction is perpendicular to the first direction and away from the elastic column 253. Wherein, the first distance is less than the second distance.

[0067] In the embodiment of the present application, through the sliding inclined plane structure between the first push rod 261 and the second locking tongue 252, the second locking tongue 252 releases the second hook body 245 when moving a first distance in the third direction, and the side baffle 258 releases the third elastic member 254 when moving a second distance. In this way, the second locking tongue 252 can successively release the second hook body 245 (corresponding to the second elastic member 246) and the third elastic member, with a simple, stable and reliable structure.

[0068] In some implementation manners, as Figure 6 , Figure 8 shown, at least one first guide seat 267 is provided on one side of the frame body 251 close to the push plate 255, and at least one first guide rod 266 and a second guide seat 265 are provided on one side of the push plate 255. The elastic column 253 is sleeved in the inner cavity of the second guide seat 265. An outer retaining ring is provided at one end of the elastic column 253 close to the push plate 255, and an inner retaining ring is provided at one end of the inner cavity of the second guide seat 265 close to the frame body 251. This can prevent the elastic column 253 from slipping out of the inner cavity when sliding in the inner cavity of the second guide seat 265. The third elastic member 254 is sleeved in the elastic column 253 and the second guide seat 265, and the reciprocating movement of the first elastic column 253 in the first direction can run smoothly.

[0069] The first guide rod 266 is sleeved in the inner cavity of the first guide seat 267. An outer retaining ring is provided at one end of the first guide rod 266 close to the frame body 251, and an inner retaining ring is provided at one end of the inner cavity of the first guide seat 267 close to the push plate 255. The fourth elastic member is sleeved in the first guide rod 266 and the first guide seat 267. This can prevent the first guide rod 266 from slipping out of the inner cavity when sliding in the inner cavity of the first guide seat 267, with smooth guiding. The arrangement of the first guide rod 266 and the second guide seat can enable the push plate 255 to run smoothly during the process of approaching or departing from the frame body 251.

[0070] In the initial state of the fixing component, as Figure 7 in (a) ofFigure 8 As shown, the third elastic member 254 and the fourth elastic member 256 release energy, that is, they are in a free state. The top surface of the boss 259 of the third elastic member 254 does not contact the second hook body 245. The second locking tongue 252 is in a reset state under the action of the sixth elastic member 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 elastic column 253 from moving in the first direction. To prevent the first elastic member 244 from releasing energy and not compressing the second elastic member 246 during the installation process of the graphics card assembly 210, thereby driving the second locking tongue 252 to release the second hook body 245.

[0071] In some implementation manners, at least one of the foregoing first locking tongues 231 may be two first locking tongues 231, and the two first locking tongues 231 are respectively located on both sides of the center line of the sliding bracket 242. At least one of the second locking tongues 252 may be two second locking tongues 252, and the two second locking tongues 252 are respectively located on both sides of the center line of the sliding bracket 242.

[0072] In some implementation manners, the two first locking tongues 231 are symmetrically distributed about the center line of the sliding bracket 242. The first hook body 243 is an axisymmetric structure, and the first hook body 243 may be axisymmetric about the center line of the sliding bracket 242. The two second locking tongues 252 are symmetrically distributed about the center line of the sliding bracket 242. The second hook body 245 is an axisymmetric structure, and the second hook body 245 may be axisymmetric about the center line of the sliding bracket 242. The third hook body 213 is an axisymmetric structure, and the third hook body 213 may be axisymmetric about the center line of the sliding bracket 242. The thrust mechanism 250 is provided with two first push rods 261, and the two first push rods 261 respectively correspond to the two second locking tongues 252. In this way, the force is balanced and the reliability is high.

[0073] In some implementation manners, the number of the operating members 215 may be two, and the two operating members 215 are opposite to the two first push rods 261. The graphics card bracket 212 is provided with at least one seventh elastic member 217, and the at least one seventh elastic member 217 is used to reset the operating member 215. Pressing a single operating member 215 (button) alone cannot make the mechanism operate. Only when the two operating members 215 are pressed simultaneously does it take effect, so as to achieve the effect of preventing accidental touch.

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

[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 inclined surface and the second inclined surface form a sliding mating surface. The angle between the first inclined surface and the first direction is less than the angle between the second inclined surface and the first direction. Since the sliding mating surface is a line contact, it helps to reduce the movement 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 inclined surface and the fourth inclined surface form a sliding mating surface. The angle between the third inclined surface and the first direction is less than the angle between the fourth inclined surface and the first direction. The sliding mating surface is a line contact, which helps to reduce the movement resistance, reduce the force parameters and specifications of each elastic member, and contribute to the miniaturization of the overall structure.

[0076] The following further describes the graphics card fixing device 200 of the present application in combination with some possible implementation manners of the present application.

[0077] As Figure 5 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 members 233. The two first locking tongues 231 are respectively located on both sides of the first hook body, or are called the left slider and the right slider. The tail of the graphics card assembly 210 is designed with a third hook body 213, and the third hook body 213 has a hook feature. After being pushed in, it is hooked by the left and right sliders, so as to form the function of fixing the graphics card assembly 210. The eighth elastic member 233 is used to reset the first locking tongue 231 (i.e., the second locking tongue 232). The working mechanism of the first locking mechanism 230 will be described 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 tongues 231 (left and right sliders) to move to both sides, triggering the first hook body 243 (or called the locking push rod) to move in the second direction and pushing the sliding bracket 242 to move. When unlocking, under the push of the sliding bracket 242, the first hook body 243 is pushed along the first direction. When the first hook body 243 reaches a certain position, it pushes the two first locking tongues 231 and the third locking tongue 232 (in the form of a slider) to move to both sides, so that the third hook body 213 on the graphics card bracket 212 is unlocked. Under the thrust of the elastic column 253 in the thrust mechanism 250, the graphics card assembly 210 is pushed out, thus completing the disassembly action.

[0079] AsFigure 6 , Figure 8 As shown in Figure 8 , in the thrust mechanism 250, a first guide seat 267 is provided on one side of the frame body 251 close to the push plate 255. On one side of the push plate 255, two first guide rods 266 and two second guide seats 265 are provided. 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 assembly 210 is in the installed state, the second guide seat 265 is compressed by the key bracket 216 to the Figure 6 position shown. The spring (the third elastic member 254) in the elastic column 253 is compressed, and the springs (the fourth elastic members 256) of the two second guide seats 265 on both sides are also compressed. After the graphics card assembly 210 is installed, the trigger second hook body 245 is pushed in, the spring (the second elastic member 246) in the second hook body 245 is compressed, and the second hook body 245 is fixed by the left and right second locking tongues 252 at the Figure 6 position shown.

[0081] Next, in combination with the initial state, the graphics card installation state, and the graphics card unlocking state, the working mechanism of the thrust mechanism 250 will be described in detail.

[0082] 1) Initial state. As shown in (a) of Figure 7 , before the graphics card assembly 210 is inserted, the second guide seat 265 is in the released state, the third elastic member 254 in the elastic column 253 is in the free state, and the top surface of the boss 259 of the third elastic member 254 does not contact the second hook body 245. The second locking tongue 252 is in the reset state under the action of the sixth elastic member 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. The two side baffles 258 can abut against the side surfaces on both sides of the boss 259 to limit the movement of the elastic column 253 in the first direction.

[0083] 2) Graphics card installation state. As shown in (b) of Figure 7 , during the installation of the graphics card, after the graphics card assembly 210 is inserted, under the push of the key bracket 216, the spring in the second guide seat 265 is compressed. 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 (the third elastic member 254) inside the elastic column 253 is also compressed. Under the elastic force of the spring (the first elastic member 244) in the first hook body 243, the second hook body 245 moves downward (the second direction), so that the spring (the second elastic member 246) inside the second hook body 245 is compressed.

[0084] 3) Graphics card unlocking state, corresponding to the state after pressing the operating member 215. As shown in the right part of Figure 6 and Figure 7As shown in (c), when the left and right first push rods 261 are pushed in the first direction to a first preset position (for example, half of the stroke), under the cooperation of the inclined surfaces between the first push rods 261 and the second locking tongues 252, the second locking tongues 252 are pulled apart to both sides by a first distance, the second hook bodies 245 are first unlocked, and the left and right baffle plates 258 still abut against the bottom surface of the boss 259 of the elastic columns 253. At this time, because the elastic force of the spring (first elastic member 244) on the first locking mechanism 230 is greater than the elastic force of the spring (second elastic member 246) on the second hook bodies 245, the first hook bodies 243 cannot be pushed. For example, it is set that the maximum elastic force of the first elastic member 244 is 4 unit forces, the maximum elastic force of the second elastic member 246 is 3 unit forces, and the maximum elastic force of the third elastic member 254 in the elastic column 253 is 2 unit forces.

[0085] As Figure 7 shown in (c), when the left and right first push rods 261 are pushed in the first direction to a second preset position (for example, two-thirds of the stroke), the left and right baffle plates 258 move outward by a second distance under the drive of the left and right second locking tongues 252, the left and right baffle plates 258 no longer block the bottom surface of the boss 259 of the elastic column 253, the elastic column 253 is unlocked, and the elastic force of the spring in the elastic column 253 is superimposed on the elastic force of the spring in the second hook bodies 245, which can push the first hook bodies 243 to move in the first direction. The first hook bodies 243 push the first locking tongues 231 and the third locking tongues 232. After the third locking tongues 232 release the third hook bodies 213, the first locking tongues 231 lock the first hook bodies 243 under the reset action of the eighth elastic member 233. The first distance is less than the second distance.

[0086] In the embodiment of the present application, operating a single operating member 215 alone cannot unlock the second hook bodies 245 and cause the sliding bracket to move. Two operating members 215 need to be pressed simultaneously to take effect, unlocking the second hook bodies 245 and the elastic column 253. Therefore, it is possible to prevent accidental touch and avoid the graphics card being accidentally ejected due to touch.

[0087] In some implementation manners, the extension section of the first push rod 261 in the second direction passes through the guiding through hole at the outer end of the graphics card bracket 212 to form the operating member 215. Or rather, the operating member 215 can be the extension section of the first push rod 261, and the operating member 215 and the first push rod 261 can be an integral part. This helps to simplify the structural design of the graphics card assembly 210.

[0088] In some implementation manners, the graphics card bracket 212 is provided with a convex portion 218 that abuts against the graphics card 211.

[0089] Specifically, as Figure 4 shown, the graphics card bracket 212 is provided with a convex portion 218. The convex portion 218 (convex stepped shape) contacts the graphics card chip at the bottom of the graphics card 211, which can achieve the effect of heat transfer.

[0090] In some implementations, such as Figure 9 shown, in the sliding mechanism 240, a first guide rail 241 is provided with a first guide groove 247, and the sliding bracket 242 is provided with at least one second sliding rail 248. The angle between the second sliding 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 (such as thermally connected). The sliding mechanism 240 further includes:

[0091] A first heat-conducting block 270, the first heat-conducting block 270 is provided with a sliding groove 271. The first heat-conducting block 270 runs on the second sliding rail 248 of the sliding bracket 242 through the sliding groove 271. At least one slider 272 is provided on the side surface of the first heat-conducting block 270, and at least one slider 272 penetrates into the guide groove 247 of the first guide rail 241. During the movement of the sliding bracket 242 in the first direction, the first heat-conducting block 270 moves in the fourth direction. When the graphics card assembly 210 is loaded into 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 in the second direction, the first heat-conducting block 270 moves in the opposite direction of the fourth direction, and the fourth direction is perpendicular to the first direction. For example, if the first direction is the horizontal direction, the fourth direction can be the vertical direction, and the first heat-conducting block 270 can be called a lifting heat-conducting block.

[0092] The heat-conducting sliding bracket can be an integral structure or a split structure.

[0093] Optionally, the heat-conducting sliding bracket is a split structure. Such as Figure 9 shown, the sliding mechanism 240 can further include: a second heat-conducting block 249. The second heat-conducting block 249 is fixedly arranged on the sliding bracket 242 to jointly form a heat-conducting sliding bracket. The second sliding rail 248 can be provided on the second heat-conducting block 249 fixed to the sliding bracket 242. Among them, the second heat-conducting block 249 is thermally connected to the heat dissipation system 290. If the first direction is the horizontal direction, the second heat-conducting block 249 can be called a horizontal heat-conducting block.

[0094] The two sides of the sliding bracket 242 are provided with guiding parts with arc-shaped features, and can slide back and forth in the open guide grooves of the two first guide rails 241 in the first direction. The second heat-conducting block 249 can be fixed to the sliding bracket 242 by screws and slide back and forth in the first direction together under the restriction of the sliding bracket 242. The first guide groove 247 extends in the fourth direction. The bottom of the first heat-conducting block 270 is an inclined slope, and the inclined slope at the bottom of the first heat-conducting block 270 is mutually attached to the top surface of the second heat-conducting block 249. The first heat-conducting block 270 can only move up and down under the restriction of the first guide grooves 247 of the left and right first guide rails 241.

[0095] The working mechanism of the heat-conducting sliding bracket will be described in detail below.

[0096] As Figure 10 shown in (a) of [], after the graphics card is installed in place, the sliding bracket 242 moves in the first direction under the push of the second hook body 245, pushing the first heat-conducting block 270 upward to fit the graphics card mounting bracket 212, thereby realizing the heat transfer function. As Figure 10 shown in (b) of [], when the graphics card is unlocked, the sliding bracket 242 moves in the second direction, bringing the first heat-conducting block 270 down, so that the first heat-conducting block 270 is separated from the graphics card bracket 212. There are inclined slopes and guiding arc rails that cooperate with each other between the first heat-conducting block 270 and the second heat-conducting block 249. This arc rail is also called the third rail. In some embodiments, thermal grease can be filled between the contact surfaces of the first heat-conducting block 270 and the second heat-conducting block 249, which helps with heat conduction and lubrication.

[0097] In the embodiments of the present application, heat-conducting blocks and thermal grease with different heat conductivities can be replaced according to different heat dissipation requirements, and good heat dissipation can be achieved. In addition, the lifting mechanism of the first heat-conducting block 270 adopts a modular design. When there is no heat dissipation requirement for the graphics card, the split lifting heat-conducting block and horizontal heat-conducting block (i.e., the first heat-conducting block 270 and the second heat-conducting block 249) can be removed, and the entire graphics card replacement device can still be used normally, with good adaptability. While realizing the quick disassembly of the graphics card, it can also meet the heat dissipation requirements of high-power graphics cards, facilitating the later maintenance and upgrade of the device.
