[0038] It should also be noted that, unless otherwise specified and limited, the "installation", "connection", "connection" and the like used in the description of the present application should be understood broadly, for example, the connection can be fixed connection, or detachable connection, or integral connection; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through intermediate medium, or the internal communication of two elements, and those skilled in the art can understand the specific meaning of the present application according to the specific circumstances.

[0039] To this end, as shown in Figures 1 to 5 The present application discloses a linkage device as shown in Figure 1 and Figure 2 The linkage device of the present embodiment comprises: a body 1, a cavity 101 provided in the body 1, and a first through hole 102 provided on the body 1 and communicating with the cavity 101; a first body 2 and a second body 3, which are pivotally connected in the body 1; a linkage mechanism, which is connected to the first body 2 and the second body 3 respectively, and is used to make the second body 3 rotate with the first body 2; wherein: when the first body 2 rotates to a first position, the first body 2 and the second body 3 open the first through hole 102 to open the cavity 101; when the first body 2 rotates to a second position, the first body 2 and the second body 3 close the first through hole 102 to block the cavity 101.

[0040] The first body 2 can be understood as a main shaft plate, and the second body 3 is a secondary shaft plate. The second body 3 is linked with the first body 2 to rotate. When the second body 3 fails, the first body 2 can still open the first through hole 102, so that the liquid cooling connector can be normally inserted, improving the reliability of the device, thereby avoiding the liquid cooling connector from impacting the first body or the second body when the liquid cooling connector is inserted or pulled out of the liquid cooling server, and reducing the risk of the liquid cooling connector from being splashed due to structural hardware interference.

[0041] The body 1 can be composed of multiple structural components, and the main purpose is to fasten the first body 2 and the second body 3. For example, when the number of the body 1 is two, the first body 2 and the second body 3 can be respectively fixed on different bodies 1 to realize the rotatable movement of the first body 2 and the second body 3 relative to the body 1.

[0042] The second body 3 is linked with the first body 2 to rotate. When the first body 2 rotates to the first position, the first through hole 102 is opened to open the cavity 101, so that the connector of the liquid cooling server can be normally inserted through the first through hole 102 to complete the plug-in with the connector of the liquid cooling pipeline preinstalled in the cavity, so as to realize the liquid cooling circulation. When the first body 2 rotates to the second position, the first body 2 and the second body 3 close the first through hole 102 to shield the cavity 101, so as to block the liquid sprayed from the connector in the cavity 101 from being sprayed on the liquid cooling server. In addition, the second body 3 rotates with the first body 2. Even if the second body 3 fails, the first through hole 102 can still be opened to complete the plug-in of the connector, so as to reduce the possibility of the liquid cooling connector impacting the body when the liquid cooling connector is inserted or pulled out of the liquid cooling server, thereby reducing the risk of the liquid cooling connector being splashed due to structural hardware interference, and improving the reliability of the device.

[0043] In a possible implementation, the side of the body 1 opposite to the first through hole 102 is further provided with a second through hole 103. The second through hole 103 can be used for the second connector of the liquid cooling pipeline to be inserted, and the first through hole 102 can be used for the first connector of the liquid cooling server to be inserted to complete the plug-in with the second connector in the cavity 101.

[0044] It can be understood that the linkage device of the embodiment can be used for plugging between the first connector of the liquid-cooled server and the second connector of the liquid-cooled pipeline, and the second connector of the liquid-cooled pipeline enters the cavity 101 through the second through hole 103. When the first body 2 is rotated to the first position, the first through hole 102 is opened to open the cavity 101, and at this time the first connector of the liquid-cooled server can be inserted into the cavity 101 through the first through hole 102, and the second connector of the liquid-cooled pipeline is completed in the cavity 101. Plugging to realize liquid cooling circulation. When the first body 2 is rotated to the second position, the first body 2 and the second body 3 close the first through hole 102 to block the cavity 101, so as to block the liquid sprayed from the second connector in the cavity 101 from being sprayed on the liquid-cooled server. In addition, even if there is liquid spraying during the plugging of the first connector and the second connector, it will be limited in the body 1.

[0045] In one possible implementation, as shown in Figure 1 and Figure 2 , the number of the body 1 is one, and the first body 2 and the second body 3 are fixed on the body 1 to realize the rotatable movement of the first body 2 and the second body 3 relative to the body 1. It can be foreseen that the body 1 is a component of the liquid-cooled server fixing architecture, and the liquid-cooled connector is inserted into the interface of the liquid-cooled server through the first body 2 and / or the second body 3.

[0046] It can be understood that the first body 2 is pivoted on the body 1, so that the first body 2 can be rotatably moved relative to the body 1. It should be understood that the pivoting is a kind of hinged or articulated connection, which allows the rotatable movement between the first body 2 and the body 1, while maintaining certain stability and adjustability.

[0047] Among them, the number of the second body 3 can be one or more. When the number is one, it can be understood that the second body 3 is a two-stage linkage relative to the first body 2; when the number is more, it can be understood that the second body 3 is a multi-stage linkage relative to the first body 2, and in the multi-stage linkage, the plurality of second bodies 3 move in a nested manner.

[0048] It can be understood that the second body 3 is pivoted on the body 1, so that the second body 3 can be rotatably moved relative to the body 1. It should be understood that the pivoting is a kind of hinged or articulated connection, which allows the rotatable movement between the second body 3 and the body 1, while maintaining certain stability and adjustability.

[0049] The first body 2 is connected to the second body 3 through a linkage mechanism to enable the second body 3 to rotate with the first body 2. The linkage mechanism can also enable differential linkage of the first body 2 and the second body 3. For example, the first body 2 and the second body 3 are pivotally connected to the body 1. Due to the distance between the first body 2 and the second body 3, the same force applied to the first body 2 or the second body 3 causes the first body 2 and the second body 3 to produce non-same-radius motion, i.e., the second body 3 moves faster than the first body 2, so as to achieve faster closing of the second body 3 than the first body 2. Since the second body 3 is located at the middle position of the first body 2, even if the first body 2 fails to open, the second body 3 can still be opened, avoiding hard collision of the liquid cooling connector with the linkage device, thereby reducing the risk of structure hardware interference causing spatter of the nozzle when the liquid cooling server is plugged or unplugged.

[0050] As shown in Figures 1 to 10 , in the embodiment, the first body 2 includes a first shaft 201 and a first plate body 202 fastened to the first shaft 201, and the second body 3 includes a second shaft 301, a second connecting rod 302 fastened to the second shaft 301, and a second plate body 303 connected to the second connecting rod 302. The first shaft 201 and the second shaft 301 are pivotally connected to the body 1 at least at one end.

[0051] The first shaft 201 is pivotally connected to the body 1 at least at one end. It can be understood that the first shaft 201 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or to further improve the reliability of fastening the rotating shaft structure to the body 1, both ends of the first shaft 201 are rotatably connected to the body 1. The first shaft 201 has a central axis of rotation relative to the body 1.

[0052] It can be understood that the first plate body 202 is fastened to the first shaft 201, including but not limited to detachable fastening or one-piece forming, etc. The first plate body 202 is provided with at least one guide rail assembly 2021, which is used to enable the second body 3 to be linked relative to the first plate body 202 through the guide rail assembly 2021. It can be predicted that the first plate body 202 also serves as part of the gravity bearing plate of the second plate body 303. Therefore, the first plate body 202 is integrally formed with the first shaft 201, so that the component structure of the first body 2 is more firm.

[0053] As shown in Figure 4 , in a possible implementation, the length direction of the first plate body 202 is shorter than the length direction of the first shaft 201, and the connection between the first plate body 202 and the first shaft 201 is provided with a avoiding gap to further enable the first shaft 201 to be tightly nested on the body 1 for rotating motion.

[0054] As shown in Figure 1 , Figure 3 , and Figure 4As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked.

[0055] As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked.

[0056] As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked. Figure 3 Figure 4 As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked.

[0057] As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked.

[0058] As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked. Figure 3 Figure 4 As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked.

[0059] As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked. Figure 3 Figure 4 As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked.

[0060] As shown, the second shaft 301 is pivotally connected to the body 1 at least at one end, and it can be understood that the second shaft 301 is a rotating shaft structure, which can be rotatably connected to the body 1 at one end, or in order to further improve the reliability of the rotating shaft structure and the body 1, both ends of the second shaft 301 are rotatably connected to the body 1. The second shaft 301 has a central axis parallel to the central axis of the first shaft 201, and one purpose is to realize the coordination of the first shaft 201 and the second shaft 301 when they are differentially linked. Figure 4 , Figure 12 and Figure 13 ​​​As shown, in one possible implementation, the linkage mechanism is a speed-changing gear assembly 5, including an input end 501 that meshes with a first shaft 201 and an output end 502 that meshes with a second shaft 301, wherein the number of teeth at the input end 501 is greater than the number of teeth at the output end 502.

[0061] Because the number of teeth on the input end 501 is greater than that on the output end 502, when the input end 501 and the output end 502 rotate synchronously, the rotational speed of the output end 502 is faster than that of the input end 501, thus enabling differential linkage between the first plate 202 and the second plate 303. It should be foreseen that the speed-increasing gear assembly is primarily based on a gear transmission mechanism. The core component of the speed-increasing gear assembly is a planetary gear set, which consists of a sun gear, planet gears, and an internal gear ring. During operation, the input shaft drives the planet gears through the sun gear in the gearbox, causing the planet gears to rotate around the internal gear ring. This establishes a transmission relationship between the planet gears, the internal gear ring, and the sun gear, achieving power transmission. The output shaft outputs torque through the planet gears. Due to the design of the planetary gear set, the rotational speed of the output shaft is increased to the required operating speed while maintaining a constant output torque. This speed-increasing effect is achieved through a reasonable design of the gear tooth ratio. If the output shaft has more gears than the input shaft, then the rotational speed of the output shaft will be faster than that of the input shaft, achieving the speed-increasing effect.

[0062] like Figure 5 , Figure 7 , Figure 9 and Figure 10 As shown, in one possible implementation, a first elastic reset member 203 is sleeved on the first shaft 201, and the two ends of the first elastic reset member 203 abut against the first plate 202 and the body 1 respectively, and / or a third elastic reset member 305 is sleeved on the second shaft 301, and the third elastic reset member 305 abuts against the second connecting rod 302 and the body 1 respectively.

[0063] The main purpose of the first elastic reset member 203 is to achieve a reset function when the first body 2 is closed. The elastic reset member 203 includes, but is not limited to, springs, torsion springs, etc. For example, one end of the torsion spring is nested on the first shaft 201, and the other two ends abut against the first plate 202 and the body 1 respectively, so as to achieve a reset when the first body 2 needs to be closed after being opened.

[0064] The third elastic reset member 305 is mainly used to reset the first body 2 when it is closed. The third elastic reset member 305 includes but is not limited to a spring, a torsion spring, etc. For example, one end of the torsion spring is nested on the second shaft 301, and the other two ends are respectively abutted against the second connecting rod 302 and the body 1, so as to reset the first body 2 when it is closed after being opened. It can be predicted that the third elastic reset member 305 arranged on the second shaft 301 can further improve the reliability of the reset of the first body 2, so as to reduce the situation that the first body 2 cannot be reset due to insufficient reset force of the first elastic reset member.

[0065] As shown in Figures 6 to 8 , in a possible implementation, the linkage device further includes a second elastic reset member 304, one end of the second elastic reset member 304 is fastened to the first body 2, and the other end is abutted against the second plate body 303. The second elastic reset member 304 is mainly used to reset the second body 3 when it is closed. The second elastic reset member 304 includes but is not limited to a spring, a torsion spring, etc.

[0066] As shown in Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 10 , in a possible implementation, one end of the second elastic reset member 304 is fastened to the first body 2, and the other end is abutted against the second plate body 303. One end of the torsion spring is nested on the second limiting protrusion 20212 of the first body 2, and the other two ends are respectively abutted against the second plate body 303, so as to reset the second body 3 when it is closed after being opened.

[0067] As shown in Figure 11 , in a possible implementation, the second plate body 303 is provided with a buckling protrusion 3031, and the second connecting rod 302 is pivoted to the buckling protrusion 3031.

[0068] The buckling protrusion 3031 is mainly used to limit the second connecting rod 302 in the second plate body 303. The buckling protrusion 3031 can be one or more sections. The second connecting rod 302 is pivoted to the buckling protrusion 3031, which is mainly used to prevent the second connecting rod 302 from falling off the second plate body 303. The second plate body 303 and the buckling protrusion 3031 can be integrally formed or detachable. For example, when the buckling protrusion 3031 is made of rubber, it can be detachable on the second plate body 303. The second connecting rod 302 overcomes the material characteristics that the rubber has a certain elastic deformation, so as to limit the second connecting rod 302 in the second plate body 303.

[0069] In combination with Figure 1 , Figure 3 and Figure 4As shown, in one possible implementation, the area of ​​the first plate 202 is larger than the area of ​​the second plate 303, and / or the second plate 303 is made of a non-rigid material, and / or the second plate 303 is provided with at least one gap 3032.

[0070] The first plate 202 serves as the main door and has a notch. The second plate 303 serves as the secondary door and is used to close and open the notch. Even if the first plate 202 cannot be opened due to a malfunction, the second plate 303 can still be opened. This avoids the liquid cooling connector being directly installed on the linkage device, thereby improving the effect of preventing structural hardware interference that could cause the nozzle to splash when the liquid cooling server is plugged in or unplugged from the liquid cooling connector.

[0071] Non-rigid materials include, but are not limited to, rubber, plastics, and foam. However, this non-rigid material is only one possible implementation of this disclosure. In another possible implementation, the second plate 303 can also be a rigid material, such as iron or aluminum alloy. When the liquid cooling joint is impacted, the non-rigid material can effectively buffer the damage caused by the collision between the components.

[0072] The second plate 303 has two gaps 3032, which further reduce the stress damage caused by blind insertion interference of components when the liquid cooling connector is impacted, thereby further reducing the risk of nozzle splashing due to structural hardware interference when the liquid cooling server is plugged in or unplugged from the liquid cooling connector. There can be one or more gaps 3032, and it should be foreseeable that the gaps 3032 can divide the second plate 303 into multiple structural segments.

[0073] like Figure 4 As shown, in one possible implementation, one end of the guide rail assembly 2021 is provided with a first limiting protrusion 20211, and the first plate 202 is provided with a second limiting protrusion 20212. The first limiting protrusion 20211 and the second limiting protrusion 20212 are used to restrict the movement of the second plate 303 within the guide rail assembly 2021.

[0074] It should be understood that the first limiting protrusion 20211 can be a stop structure set at the front end of the guide rail assembly 2021, the main purpose of which is to prevent the second plate 303 from detaching from the first plate 202 when it moves forward along the guide rail assembly 2021.

[0075] The second limiting protrusion 20212 can be a stop structure located behind the guide rail assembly 2021, away from the first limiting protrusion 20211. Its main purpose is to prevent the second plate 303 from detaching from the first plate 202 when it moves backward along the guide rail assembly 2021. Here, "behind" can mean on the rear end of the guide rail assembly 2021, or not on the guide rail assembly 2021, but on the first plate 202, only the direction is relative to the rear of the guide rail assembly 2021.

[0076] As shown in Figure 4 , in a possible implementation, the second limiting protrusion 20212 has a buckle protrusion 202121 for further preventing the second plate body 303 from moving forward out of the first plate body 202 along the guide rail assembly 2021, and the second elastic reset member 304 can be embedded and fastened on the second limiting protrusion 20212 at one end and abut against the second plate body 303 at the other end.

[0077] As shown in Figure 3 , Figure 4 and Figure 14 , the embodiment also discloses a liquid-cooled server anti-spraying device, which comprises the linkage device of any possible implementation and further comprises a protrusion structure 4 arranged on the first body 2 or the second body 3.

[0078] It should be understood that when the protrusion structure 4 is arranged on the first body 2, the first body 2 acts as a driving door due to the force of the liquid-cooled server acting on the protrusion structure 4 when the liquid-cooled server is inserted into the liquid-cooled connector, thereby driving the second body 3 to link and realize the differential linkage effect of the first body 2 and the second body 3.

[0079] When the protrusion structure 4 is arranged on the second body 3, the second body 3 acts as a driving door due to the force of the liquid-cooled server acting on the protrusion structure 4 when the liquid-cooled server is inserted into the liquid-cooled connector, thereby driving the first body 2 to link and realize the differential linkage effect of the first body 2 and the second body 3.

[0080] As shown in Figures 1 to 14 , the linkage device and the liquid-cooled server anti-spraying device of the embodiment of a possible implementation have at least the following characteristics:

[0081] 1. The first plate body 202 and the second plate body 303 are linked and rotated by the linkage mechanism, so that the second body 3 moves on the guide rail assembly 2021 of the first plate body 202. In the event of any failure of the first plate body 202 and the second plate body 303, the other plate body can still be opened, ensuring that the liquid-cooled connector can pass normally and preventing the risk of structure hardware interference causing the spray to splash when the liquid-cooled server is inserted into or pulled out of the liquid-cooled connector.

[0082] 2. The first plate body 202 and the second plate body 303 are automatically reset by the first elastic reset member 203, the second elastic reset member 304 and the third elastic reset member 305. When the liquid-cooled connector is pulled out, the first plate body 202 and the second plate body 303 are automatically closed.

[0083] 3、Second plate body 303 is made of non-rigid material, and gap 3032 is opened on second plate body 303, when liquid cooling plug blind insertion interference occurs, through non-rigid material, the damage of collision between parts can be effectively buffered.

[0084] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
