[0042] The technical scheme of the present application will be further described in detail below with reference to the accompanying drawings and specific examples.

[0044] It should also be noted that, unless otherwise defined and limited, the "installation", "connection", "connection" and the like used in the description of the present application should be understood in a broad sense, 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 an intermediate medium, or the connection between two elements, the person skilled in the art can understand the specific meaning of the present application according to the specific circumstances.

[0045] To this end, as shown in FIGS. 1-5, the linkage device of the present application comprises a body 1, a cavity 101 provided in the body 1, a first through hole 102 provided in the body 1 and communicating with the cavity 101, a first body 2 and a second body 3 pivoted in the body 1, and a linkage mechanism connecting the first body 2 and the second body 3, respectively, and used to rotate the second body 3 following the first body 2. When the first body 2 is rotated 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 is rotated to a second position, the first body 2 and the second body 3 close the first through hole 102 to block the cavity 101.

[0046] The first body 2 can be understood as a main shaft plate, and the second body 3 is a secondary shaft plate. When the second body 3 fails, the first body 2 can still open the first through hole 102 to allow the liquid cooling connector to be normally inserted, thereby improving the reliability of the device, and avoiding the liquid cooling connector from impacting the first body 2 or the second body 3 when the liquid cooling connector is inserted or removed from the liquid cooling server, thereby reducing the risk of liquid spattering caused by structural hardware interference.

[0047] The body 1 can be composed of multiple structural components, and its 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 fixed on different bodies 1, respectively, to realize the rotatable movement of the first body 2 and the second body 3 relative to the body 1.

[0048] The linkage mechanism is used to rotate the second body 3 following the first body 2. When the first body 2 is rotated 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 prearranged in the cavity, thereby realizing the 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, thereby preventing the liquid ejected from the connector in the cavity 101 from being sprayed onto the liquid cooling server. In addition, the second body 3 rotates following 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, thereby reducing the possibility of the liquid cooling connector impacting the body when the liquid cooling connector is inserted or removed from the liquid cooling server, and further reducing the risk of liquid spattering caused by structural hardware interference of the liquid cooling connector, thereby improving the reliability of the device.

[0049] In some embodiments, the body 1 is further provided with a second through hole 103 on the side opposite to the first through hole 102, which can be used for the insertion of the second connector of the liquid cooling pipeline, and the first through hole 102 can be used for the insertion of the first connector of the liquid cooling server to complete the plug-in with the second connector in the cavity 101.

[0050] It can be understood that the linkage device of the embodiment can be used for the plug-in between the first connector of the liquid cooling server and the second connector of the liquid cooling pipeline, and the second connector of the liquid cooling 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 cooling server can be inserted into the cavity 101 through the first through hole 102 and complete the plug-in with the second connector in the cavity 101 to realize the 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 that the liquid sprayed from the second connector in the cavity 101 can be prevented from being sprayed on the liquid cooling server. In addition, even if there is liquid spraying during the plug-in of the first connector and the second connector, it will be limited in the body 1.

[0051] In some embodiments, as shown in FIG. 1 and FIG. 2, the number of the body 1 is one, and the first body 2 and the second body 3 are both 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. In an optional example, the body 1 is a component of a liquid cooling panel server fixing frame, and the liquid cooling connector is inserted into the interface of the liquid cooling panel server through the first body 2 and / or the second body 3.

[0052] It can be understood that the first body 2 is pivoted on the body 1, so that the first body 2 can rotate relative to the body 1. It should be understood that the pivoting is a kind of hinging or joint connection, which allows the rotatable movement between the first body 2 and the body 1, while maintaining a certain stability and adjustability.

[0053] In the formula, the number of the second body 3 can be one or more. When the number is one, it can be understood as a two-stage linkage of the second body 3 relative to the first body 2. When the number is more, it can be understood as a multi-stage linkage of the second body 3 relative to the first body 2, and in the multi-stage linkage, the plurality of second bodies 3 move in a nested manner.

[0054] It can be understood that the second body 3 is pivoted on the body 1, so that the second body 3 can rotate relative to the body 1. It should be understood that the pivoting is a kind of hinging or joint connection, which allows the rotatable movement between the second body 3 and the body 1, while maintaining a certain stability and adjustability.

[0055] The first body 2 is connected to the second body 3 through a linkage structure to enable the second body 3 to rotate with the first body 2. The linkage structure 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. Because of 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. Because 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 to reduce the risk of spattering of the nozzle caused by structural hardware interference of the liquid cooling server when the liquid cooling connector is inserted or pulled out.

[0056] As shown in FIGS. 1-10, in the present 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.

[0057] 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.

[0058] 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.

[0059] As shown in FIG. 4, in some embodiments, 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.

[0060] As shown in FIG. 1, FIG. 3 and FIG. 4, 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, the two ends of the second shaft 301 are rotatably connected to the body 1. Among them, the second shaft 301 has a central axis relative to the body 1 and is parallel to the central axis of the first shaft 201, and one of the purposes is to realize the mutual coordination of the first shaft 201 and the second shaft 301 when they are differentially linked.

[0061] Among them, the second connecting rod 302 is fastened to the second shaft 301, including but not limited to detachable fastening or integral molding, etc. And it can be foreseen that the second connecting rod 302 is integrally formed with the second shaft 301, so that the component structure of the second connecting rod 302 is more firm.

[0062] As shown in FIG. 3 and FIG. 4, in some embodiments, the linkage structure is a sliding assembly, which includes a guide rail assembly 2021 provided on the first plate body 202, and the second plate body 303 is movably provided on the guide rail assembly 2021.

[0063] Among them, the second plate body 303 is nested on the guide rail assembly 2021, and when the first plate body 202 rotates, it pushes the second plate body 303 to move on the guide rail assembly 2021.

[0064] As shown in FIG. 3 and FIG. 4, in some embodiments, the second connecting rod 302 and the first plate body 202 have a certain included angle α, wherein the angle α includes but is not limited to an acute angle, etc.

[0065] As shown in FIG. 3 and FIG. 4, the second plate body 303 is nested in the second connecting rod 302, so that the second plate body 303 will not fall off the second connecting rod 302. Among them, the cross-sectional shape of the second connecting rod 302 at the nesting part of the second plate body 303 and the second connecting rod 302 is circular or circular-like, and the shape of the part other than the nesting part can be the same as or different from that of the nesting part. It can be foreseen that the design of the cross-sectional shape of the nesting part as a circular or circular-like structure is beneficial to the differential linkage effect of the first body 2 and the second body 3, and further reduces the occurrence of poor linkage or poor linkage effect. The second plate body 303 is nested in the guide rail assembly 2021 to move on the guide rail assembly 2021 to realize the opening and closing movement of the second plate body 303.

[0066] As shown in FIG. 4, FIG. 12 and FIG. 13, in some embodiments, the linkage structure is a variable speed gear assembly 5, which includes an input end 501 engaged with the first shaft 201 and an output end 502 engaged with the second shaft 301, and the number of teeth of the input end 501 is greater than that of the output end 502.

[0067] Since the number of teeth of the input end 501 is greater than that of the output end 502, when the input end 501 and the output end 502 rotate synchronously, the rotation speed of the output end 502 is faster than that of the input end 501, so that the first plate body 202 and the second plate body 303 are differentially linked. It can be foreseen that the variable speed gear assembly 5 is mainly based on the mechanism of gear transmission. The core component of the variable speed gear assembly 5 can select a conventional mechanical transmission device, such as a planetary gear set, which mainly consists of a sun gear, a planet gear and an internal ring gear. In operation, the input shaft drives the planet gear through the sun gear in the gear box, so that the planet gear rotates around the internal ring gear. In this way, the planet gear forms a transmission relationship with the internal ring gear and the sun gear, realizing the transmission of power, and the output shaft outputs the torque of the planet gear. Due to the design of the planetary gear set, the rotation speed of the output shaft will be increased to the required working speed while keeping the output torque constant. This speed-up effect is achieved by reasonably designing the gear ratio of the gears. If the gear of the output shaft is more than that of the input shaft, the rotation speed of the output shaft will be faster than that of the input shaft, achieving the speed-up effect. In the embodiment, the planetary gear set is used to form the variable speed gear assembly 5, the input shaft is designed as the input end 501 meshing with the first shaft 201, and the output shaft is designed as the output end meshing with the second shaft 301. In this way, the planetary gear set is formed as a linkage structure connected between the first shaft 201 and the second shaft 301 by using the gear transmission mechanism of the planetary gear set, so as to realize the differential rotation between the first body 2 and the second body 3.

[0068] As shown in FIGS. 5, 7, 9 and 10, in some embodiments, 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 body 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.

[0069] The first elastic reset member 203 is sleeved on one end of the first shaft 201 and is mainly used for resetting the closing of the first body 2. The elastic reset member 203 includes but is not limited to a spring, a torsional spring and the like. For example, one end of the torsional spring is nested on the first shaft 201, and the other two ends abut against the first plate body 202 and the body 1, respectively. When the first body 2 is opened, the first plate body 202 rotates relative to the body 1, so that the first elastic reset member 203 is deformed. The elastic force generated by the deformation of the first elastic reset member 203 provides driving force for switching the first body 2 to the closed state, thereby realizing the resetting when the first body 2 needs to be closed after being opened.

[0070] The third elastic reset member 305 is sleeved on one end of the second shaft 301, and is mainly used for resetting the closing of the first body 2. 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 main body 1. When the first body 2 is opened, the first plate body 202 rotates relative to the main body 1. At this time, the second plate body 304 arranged on the first plate body 202 rotates synchronously, so that the third elastic reset member 305 is deformed, and the elastic force generated by the deformation of the third elastic reset member 305 provides driving force to the second plate body 304, that is, the first body 2 switches to the closing state, thereby realizing the resetting when the first body 2 needs to be 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 resetting of the first body 2, so as to reduce the situation that the resetting cannot be performed due to insufficient resetting force of the first elastic reset member 203.

[0071] As shown in FIGS. 6-8, in some embodiments, the linkage device further includes a second elastic reset member 304, one end of the second elastic reset member 304 being fastened to the first body 2, and the other end being abutted against the second plate body 303. The main purpose of the second elastic reset member 304 is to realize the resetting of the closing of the second body 3. The second elastic reset member 304 includes but is not limited to a spring, a torsion spring, etc.

[0072] As shown in FIGS. 3, 4, 7, 8 and 10, in some embodiments, 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 includes a sleeving part 3041 and elastic arms 3042 extending outward from the sleeving part 3041. The sleeving part 3041 is sleeved and arranged on the second limiting protrusion 20212 of the first body 2. The elastic arms 3042 extend outward from the sleeving part 3041 and are gradually expanded. The distal ends of the two elastic arms 3042 away from the sleeving part 3041 are respectively abutted against the position where the second plate body 303 and the second connecting rod 302 are connected, thereby realizing the resetting when the second body 3 needs to be closed after being opened.

[0073] As shown in FIG. 11, in some embodiments, 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. As shown in FIG. 4, the second connecting rod 302 includes first and second parallel rods 3021 and 3022 extending perpendicularly from opposite ends of the second shaft 301, and a vertical rod 3023 connected between the first and second parallel rods 3021 and 3022. The buckling protrusion 3031 is pivotally connected with the vertical rod 3023. In this embodiment, the distal end of the elastic arm 3042 of the second elastic reset member 304 is abutted against one side of the buckling protrusion 3031 of the second plate body 303.

[0074] The buckle protrusion 3031 is mainly used to limit the second connecting rod 302 in the second plate body 303. The buckle protrusion 3031 can be one or more sections. The second connecting rod 302 is pivoted to the buckle 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 buckle protrusion 3031 can be integrally formed or detachable structure, for example, when the buckle protrusion 3031 is made of rubber, it can be detachably connected to the second plate body 303. The second connecting rod 302 can make full use of the material characteristics of the rubber that has a certain elastic deformation to be more reliably installed in the buckle protrusion 3031, so as to limit the second connecting rod 302 in the second plate body 303.

[0075] In combination with FIGS. 1, 3 and 4, in some embodiments, the area of the first plate body 202 is greater than the area of the second plate body 303, and / or the second plate body 303 is made of a non-rigid material, and / or the second plate body 303 is provided with at least one gap 3032.

[0076] In this embodiment, the guide rail assembly 2021 is provided with a guide rail groove 2022 extending along the width direction of the first plate body 202 perpendicular to the first shaft 201, and the notch 204 is arranged between the upper and lower guide rail grooves 2022 on the first plate body 202. The upper and lower opposite ends of the second body 303 are slidably installed in the guide rail groove 2022, and the second body 303 slides in the guide rail groove 2022 to cover or expose the notch 204. It should be noted that since the first body 2 and the second body 3 are connected by the linkage mechanism, when the first body 2 rotates, the second body 3 rotates with the first body 2 and forms differential rotation, and the second body 3 can expose the notch 204 earlier than the rotation speed of the first body 2, so that the liquid cooling connector is inserted into the cavity 101 of the body 1 based on the position of the notch 204. As the liquid cooling connector is further inserted, the liquid cooling connector presses the first body 2 and enters the cavity 101 as a whole, and at the same time, the liquid cooling connector can also completely block the first through hole 102 to avoid the risk of spatter.

[0077] The non-rigid material includes, but is not limited to, rubber, plastic, foam, etc. However, the non-rigid material is only one possible embodiment of the present disclosure. In another possible embodiment, the second plate body 303 can also be a rigid material, such as iron, aluminum alloy, etc. When the liquid cooling connector is impacted, the non-rigid material can effectively buffer the damage caused by the collision between the components.

[0078] The second plate body 303 is provided with two gaps 3032, which can further reduce the related stress damage caused by the blind insertion interference of the components when the liquid cooling connector is impacted, thereby further reducing the risk of spattering of the nozzle caused by the structural hardware interference of the liquid cooling server when plugging the liquid cooling connector. The gap 3032 can be one or more. The gap 3032 extends in a transverse direction perpendicular to the second shaft 301 on the second plate body 303, and can divide the second plate body 303 into multiple segments.

[0079] As shown in FIG. 4, in some embodiments, one end of the guide rail assembly 2021 is provided with a first limiting protrusion 20211, and the first plate body 202 is provided with a second limiting protrusion 20212. The first limiting protrusion 20211 and the second limiting protrusion 20212 are used to limit the movement of the second plate body 303 in the guide rail assembly 2021.

[0080] It should be understood that the first limiting protrusion 20211 can be a stop block structure arranged at the front end of the guide rail assembly 2021, and the main purpose is to prevent the second plate body 303 from moving forward along the guide rail assembly 2021 and separating from the first plate body 202.

[0081] The second limiting protrusion 20212 can be a stop block structure arranged away from the first limiting protrusion 20211 at the rear of the guide rail assembly 2021, and the main purpose is to prevent the second plate body 303 from moving backward along the guide rail assembly 2021 and separating from the first plate body 202. Wherein, the rear can be on the rear end of the guide rail assembly 2021, or not on the guide rail assembly 2021, but on the first plate body 202, only the direction is relative to the rear of the guide rail assembly 2021.

[0082] As shown in FIG. 4, in some embodiments, the second limiting protrusion 20212 has a buckle protrusion 202121, which is used to further prevent the second plate body 303 from moving forward along the guide rail assembly 2021 and separating from the first plate body 202, and the other end of the second elastic reset member 304 can be embedded and fastened on the second limiting protrusion 20212, and the other end abuts against the second plate body 303.

[0083] As shown in FIGS. 3, 4 and 14, the present embodiment also discloses a liquid cooling server anti-spraying device, which comprises the linkage device of any of the above embodiments.

[0084] Wherein, in the linkage device, the first body 2 and the second body 3 are rotationally connected by the linkage mechanism to form a half-door structure, and two half-door structures are arranged on the opposite sides of the corresponding first through hole 102. Optionally, please refer to Fig. 1 again, the body 1 is further provided with a through hole 104 at a position close to the first through hole 101, and the first body 2 or the second body 3 is provided with a protruding structure 4. In each half-door structure, the first body 2 and the second body 3 are located on the inner side of the first through hole 101, that is, in the cavity 101, and the protruding structure 4 is correspondingly provided through the through hole 104 and protrudes out of the body 1. In this way, when the liquid cooling server is plugged into the liquid cooling connector, it will first contact the protruding structure 4, and by pressing the protruding structure 4, an extrusion force is formed on the first body 2 or the second body 3.

[0085] It should be understood that the protruding structure 4 is provided, and when the liquid cooling server is plugged into the liquid cooling connector, it will first contact the protruding structure 4. Therefore, when the protruding structure 4 is arranged on the first body 2, the first body 2 can be used as the active door to drive the second body 3 to move in linkage, thereby realizing the differential linkage effect of the first body 2 and the second body 3.

[0086] When the protruding structure 4 is arranged on the second body 3, the second body 3 can be used as the active door to drive the first body 2 to move in linkage, thereby realizing the differential linkage effect of the first body 2 and the second body 3.

[0087] In combination with Figs. 1 to 14, the linkage device and the liquid cooling server anti-spraying device provided by the embodiments of the present application have at least the following characteristics:

[0088] 1. The linkage mechanism is used to link and rotate the first plate body 202 and the second plate body 303, 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 cooling connector can pass normally and preventing the risk of spattering of the spray head when the liquid cooling server is plugged into or pulled out of the liquid cooling connector.

[0089] 2. The first elastic return member 203, the second elastic return member 304 and the third elastic return member 305 are used to automatically reset the first plate body 202 and the second plate body 303, so that the first plate body 202 and the second plate body 303 are automatically closed when the liquid cooling connector is pulled out.

[0090] 3. The second plate body 303 is made of a non-rigid material, and a gap 3032 is formed in the second plate body 303. When interference occurs in the blind insertion of the liquid cooling plug, the non-rigid material can effectively buffer the damage caused by the collision between components.

[0091] The above description is only specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
