[0002] A server provides computing or application services for other clients in a network. The server has high-speed CPU operation capability, long-time reliable operation, powerful I / O external data throughput capability and better scalability. A plurality of server fan modules are usually arranged in a wind-cooled server, and the plurality of server fan modules are installed side by side in a fan module installation space of a server case to provide directional cooling air flow in the server case, thereby effectively cooling internal components of the server and ensuring normal and stable operation of each component of the server.

[0003] In order to improve the maintainability of the server fan module, the server fan needs to realize tool-free disassembly and plugging, and the tool-free disassembly and plugging of the traditional server fan module is usually implemented in the following ways:

[0004] 1. A handle is pulled to realize plugging by pulling a side locking piece; the fan frame is provided with locking pieces on both sides, the tail of the locking piece is extended and rolled into a handle, and the locking piece is pulled to realize plugging. For the above-mentioned way, directly pulling the locking piece often causes excessive bending, the locking piece is easy to be damaged, the service life is reduced, and the use reliability is poor.

[0005] 2. A fixed part and a pressing bracket are installed on one side of the handle, which can convert the longitudinal force into the transverse force, and only longitudinal force needs to be applied to realize the disassembly of the fan. For the above-mentioned way, the handle is a fixed part, the fan handle occupies a large space, the case panel cannot be installed compactly, the product positioning is affected, and there are many parts and the operation is complicated. SUMMARY

[0006] In order to solve the problems of poor use reliability of the tool-free disassembly mode of the traditional server fan module, large space occupied by the fan handle, inability to compactly install the case panel, affecting product positioning, and many parts and complicated operation, the application provides a server fan module and a server.

[0007] The application is implemented by the following technical solutions:

[0008] A server fan module includes a front window assembly, a fan body, and a rear window assembly connected and installed sequentially from front to back. The front window assembly includes a handle, a pull member, a locking rod, and a frame-shaped front window panel. A horizontal mounting bracket is provided inside the front window panel. The pull member includes a pull shaft and a wedge connected front and rear. A pull shaft guide hole is provided on the mounting bracket for the pull shaft to slide through. The front end of the pull shaft is connected and installed to the handle. The locking rod is slidably installed on the mounting bracket from left to right. One end of the locking rod is supported by a second spring, and the other end of the locking rod is provided with a locking block that can slide out of the outer surface of the front window panel. The rear edge of the locking block end is provided with a chamfered surface. A slot is provided on the locking rod. An inclined locking rod guide surface is provided on the side of the slot near the second spring. The wedge is provided with a wedge pressing surface that can fit and press against the locking rod guide surface.

[0009] A further improvement of the present invention is that a first spring is mounted on the pull shaft, with its two ends respectively abutting against the wedge block and the mounting bracket.

[0010] A further improvement of the present invention is that the cross-section of the pull shaft guide hole is non-circular, and the pull shaft is adapted to the shape of the pull shaft guide hole.

[0011] A further improvement of the present invention is that the cross-section of the guide hole of the pull shaft is D-shaped.

[0012] A further improvement of the present invention is that the front end of the pull shaft is provided with a pull shaft positioning notch, and the rear side of the handle is provided with a pull shaft positioning groove, and the pull shaft positioning groove is provided with a pull shaft positioning protrusion that can be inserted and positioned with the pull shaft positioning notch.

[0013] A further improvement of the present invention is that a V-shaped handle positioning groove is provided on the front side of the mounting bracket, and a handle positioning protrusion that engages with the handle positioning groove is provided on the rear side of the handle.

[0014] A further improvement of the present invention is that the mounting bracket is provided with a boss that can limit the forward movement of the wedge block to its extreme position.

[0015] A further improvement of the present invention is that the mounting bracket is provided with a limiting block that can guide and limit the left and right sliding of the locking rod.

[0016] A further improvement of the present invention is that a front window guard net is fastened and installed on the rear side of the front window panel.

[0017] Another aspect of the present invention is achieved through the following technical solution:

[0018] A server includes a server chassis and a server fan module; the server chassis has a plurality of fan module mounting spaces, and the side wall of the fan module mounting space has a stop hole that can be inserted and limited by a card block.

[0019] As can be seen from the above technical solutions, the beneficial effects of the present invention are:

[0020] When the server fan module is installed, the handle is pushed to push the entire server fan module into the fan module installation space. When the clamping block abuts against the side wall of the fan module installation space, the locking rod is guided and extruded by the rear chamfer surface of the end of the clamping block, so that the locking rod is moved right and retracted as a whole until the clamping block is aligned with the stop hole on the side surface of the fan module installation space. The locking rod is automatically extended under the elastic support of the second spring, so that the clamping block is automatically clamped into the stop hole, thereby realizing reliable and convenient installation of the server fan module. When the server fan module is disassembled, the handle is pulled forward, so that the pulling member is pulled forward, and the locking rod guide surface on the slot is pressed by the wedge pressing surface on the wedge block. Since the fitting surface has a certain inclination angle, the locking rod is pushed right by the horizontal component force, so that the clamping block is retracted into the through hole. By continuously pulling the handle forward, the server fan module can be conveniently unlocked and disassembled. Only the forward and backward pushing and pulling force is needed to conveniently disassemble and assemble the server fan module without other operations, thereby simplifying the operation and improving the operation experience. The unlocking mechanism has a simple structure, the handle is a switch, occupies a small space, and has few parts, so that the compact installation of the case panel can be realized, and the practicality is good.

Obviously, the embodiments described below are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present patent, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present patent.

[0034] As Figure 1 , 2, 8, 9, an optional embodiment of the application discloses a server fan module, comprising front window assembly 1, fan body 2 and rear window assembly 5 connected and installed in sequence from front to back, front window assembly 1 comprises handle 11, pulling member 13, locking rod 15 and frame-shaped front window panel 14, front window panel 14 is internally provided with transverse mounting bracket 144, mounting bracket 144 is integrally T-shaped and presents a shell structure with front convexity and rear opening, pulling member 13 comprises front and rear connected pulling shaft 131 and wedge block 132, mounting bracket 144 is provided with pulling shaft guide hole 149 for front and rear sliding penetration of pulling shaft 131 in the middle of the front side, the front end of pulling shaft 131 is connected and installed with handle 11 through connecting screw 17, locking rod 15 is slidably installed in mounting bracket 144, and the right end of locking rod 15 is elastically supported with second spring 18, the left end of locking rod 15 is provided with clamping block 151, and the left side of front window panel 14 is provided with through hole 146 for sliding extension of clamping block 151, locking rod 15 is provided with front and rear direction slot 154 in the middle, the right rear edge of slot 154 is provided with inclined locking rod guide surface 152, and the right front edge of wedge block 132 is provided with wedge block pressing surface 135 capable of being attached to locking rod guide surface 152 and sliding and pressing locking rod guide surface 152.

[0035] When handle 11 is not subjected to pulling force, second spring 18 has leftward elastic force on locking rod 15, so that clamping block 151 at the left end of locking rod 15 can extend out of through hole 146, when the server fan module is installed, the entire server fan module is pushed into fan module installation space 61 by pushing handle 11, when clamping block 151 abuts against the side wall of fan module installation space 61, the locking rod 15 is right-removing and retracted as a whole (second spring 18 is pressed) by the guidance and extrusion of the end rear edge chamfer surface of clamping block 151, until clamping block 151 is aligned with stop hole 62 on the side of fan module installation space 61, the locking rod 15 automatically extends under the elastic support of second spring 18, so that clamping block 151 is automatically clamped into stop hole 62, realizing reliable and convenient installation of the server fan module, when the server fan module is disassembled, handle 11 is pulled forward, realizing forward pulling of pulling member 13, wedge block 132 is pressed on locking rod guide surface 152 on slot 154 by wedge block pressing surface 135 on wedge block 132, because the attachment surface has a certain inclination angle, locking rod 15 is right-removed (overcoming the elastic force of second spring 18) by transverse component force, so that clamping block 151 is retracted into through hole 146, and handle 11 is continuously pulled forward, realizing convenient unlocking and disassembly of the server fan module. Only forward and backward pushing and pulling force is needed to realize convenient tool-free disassembly of the server fan module, without other operations, simplifying operation actions and improving operation experience, and the unlocking mechanism is simple in structure, handle 11 is a switch, small in space occupation, few in parts, can realize compact installation of the case panel, and is good in practicability.

[0036] It should be noted that the server fan module has a certain static friction force F1 with the fan module mounting space 61, and the maximum value of the pulling force on the handle 11 before the clamping block 151 is completely retracted into the through hole 146 is F2, and the pulling force on the server fan module is F3, and it is necessary to ensure that F1 is not less than F2, so as to avoid the clamping block 151 from being stuck with the stop hole 62 on the side of the fan module mounting space 61, and to ensure the smoothness of the operation.

[0037] As shown in Figures 8-9 , the wedge pressing surface 135 and the locking rod guide surface 152 have an inclination angle of 45 degrees, and are finely polished smooth surfaces with very small static friction, ensuring the smoothness of the wedge 132 pressing the locking rod 15.

[0038] As shown in Figures 8-9 , a spring second positioning protrusion 155 is arranged at the right end of the locking rod 15, and a spring first positioning protrusion 148 is arranged at the right side of the mounting bracket 144, and the second spring 18 is positioned and inserted by the spring second positioning protrusion 155 and the spring first positioning protrusion 148, so as to ensure the reliability of the extension and retraction action of the second spring 18 and avoid the deviation of the second spring 18.

[0039] As shown in Figure 3 , the handle 11 is bent at both ends, which is convenient for pulling operation and holding force; and the mounting bracket 144 with the front convex T-shaped structure ensures sufficient finger holding space in the narrow space of the front window assembly 1, which is convenient for pulling operation of the handle 11.

[0040] As shown in Figure 1 , the front window panel 14 is buckled and mounted on the rear side of the front window panel 14. The inner side of the frame-shaped structure of the front window panel 14 is provided with a support plate with honeycomb holes, and the mounting bracket 144 is transversely arranged in the middle of the support plate. The front window guard net 16 is provided with honeycomb holes consistent with the positions of the honeycomb holes on the support plate, which can only reduce the wind resistance while ensuring the filtering and purification function, and improve the heat dissipation efficiency of the server fan module. The front window guard net 16 is buckled and mounted on the rear side of the front window panel 14 through the elastic buckle and the convex point, so as to realize the closure of the rear opening of the mounting bracket 144, realize the isolation of the unlocking mechanism and the fan body 2, and ensure the reliable and safe operation of the fan body 2.

[0041] As shown in Figure 1 , the front window assembly 1, the fan body 2 and the rear window assembly 5 are placed in order from front to back, and three long screws 4 and a light guide column 3 pass through the mounting holes on the rear window assembly 5 and the mounting holes on the fan body 2 in turn, the front ends of the three long screws 4 are screwed and installed with the three panel nuts 141 on the rear side of the front window assembly 1 (as shown in Figure 5 ), and the front end of the light guide column 3 is inserted into the panel light hole 143 on the rear side of the front window assembly 1 (as shown in Figures 2-4As shown in the figure), reliable connection and installation of the front window assembly 1, the fan body 2 and the rear window assembly 5 are achieved, and the problem of the rear window assembly 5 being warped is avoided.

[0042] Further, as shown in the figure Figure 2 To ensure the accuracy and reliability of the installation of the light guide column 3, a light guide column positioning hole 52 is formed on the rear window assembly 5 and is positioned and engaged with the light guide column positioning protrusion 31 of the light guide column 3.

[0043] Further, as shown in the figure Figure 2 To achieve the accuracy of the installation of the front window assembly 1, the fan body 2 and the rear window assembly 5, a fan body anti-fumble notch 21 is formed on each of the front and rear sides of the fan body 2, the rear window positioning column 51 on the rear window assembly 5 is engaged with the fan body anti-fumble notch 21 on the rear side, the panel positioning column 142 on the front window assembly 1 is engaged with the fan body anti-fumble notch 21 on the front side, the problem of the installation angle being misaligned is effectively avoided, the installation anti-fumble effect is achieved, and the convenience of assembly is improved.

[0044] In another optional embodiment of the application, a server fan module is disclosed, which comprises a front window assembly 1, a fan body 2 and a rear window assembly 5 connected and installed in sequence from front to back, the front window assembly 1 comprises a handle 11, a pulling member 13, a locking rod 15 and a frame-shaped front window panel 14; the front window panel 14 is internally provided with a transverse mounting bracket 144, the mounting bracket 144 as a whole is in a T-shaped structure and is in a shell structure with a front convex portion and a rear open portion, the pulling member 13 comprises a pulling shaft 131 and a wedge block 132 connected in front and back; the mounting bracket 144 is provided with a pulling shaft guide hole 149 in the middle of the front side for the pulling shaft 131 to slide and penetrate in front and back, and the pulling shaft 131 is connected and installed with the handle 11 through a connecting screw 17 at the front end; the locking rod 15 is slidably installed in the mounting bracket 144, and the right end of the locking rod 15 is elastically supported by a second spring 18, the left end of the locking rod 15 is provided with a clamping block 151, and the left side of the front window panel 14 is provided with a through hole 146 for the clamping block 151 to slide and extend out; the middle of the locking rod 15 is provided with a front and back direction slot 154, the right rear edge of the slot 154 is provided with an inclined locking rod guide surface 152, and the right front edge of the wedge block 132 is provided with a wedge block pressing surface 135 which can be attached to and slide and press the locking rod guide surface 152. As shown in the figure Figures 8-9 The pulling shaft 131 is sleeved with a first spring 12 which is in abutment with the wedge block 132 and the mounting bracket 144 at both ends. The pulling member 13 is elastically supported by the first spring 12, the reliable attachment of the handle 11 and the mounting bracket 144 is achieved without the handle 11 being pulled and operated, the idle stroke and the "clunk" phenomenon are avoided, the convenience of operation is improved, and the compactness of the structure is ensured.

[0045] When the server fan module is installed, the handle 11 is pushed to push the entire server fan module into the fan module installation space 61. When the clamping block 151 abuts against the side wall of the fan module installation space 61, the locking rod 15 is moved right back to retract (presses the second spring 18) through the guidance and extrusion of the rear chamfer surface of the end of the clamping block 151. Until the clamping block 151 is aligned with the stop hole 62 on the side of the fan module installation space 61, the locking rod 15 automatically extends under the elastic support of the second spring 18, so that the clamping block 151 is automatically clamped into the stop hole 62, realizing reliable and convenient installation of the server fan module. When the server fan module is disassembled, the handle 11 is pulled forward to realize forward pulling of the pulling member 13 (overcoming the elastic force of the first spring 12), and at the same time, the locking rod guiding surface 152 on the insertion groove 154 is pressed by the wedge block pressing surface 135 on the wedge block 132. Since the fitting surface has a certain inclination angle, the locking rod 15 is pushed right (overcoming the elastic force of the second spring 18) through the horizontal component force, so that the clamping block 151 retracts into the through hole 146. Continue to pull the handle 11 forward to realize convenient unlocking and disassembly of the server fan module. Only the forward and backward pushing and pulling force is needed to realize convenient tool-free disassembly of the server fan module, without other operations, simplifying the operation action and improving the operation experience. The unlocking mechanism has simple structure, the handle 11 is a switch, occupies small space, has few parts, can realize compact installation of the case panel, and has good practicability.

[0046] As shown in Figure 8 When the clamping block 151 is fully extended (the left end of the locking rod 15 can abut against the side of the front window panel 14, or the wedge block 132 can press and limit the locking rod 15 to limit the extension length of the clamping block 151), the wedge block pressing surface 135 closely abuts against the locking rod guiding surface 152, that is, the handle 11 abuts against the mounting frame 144, and the first spring 12 is not fully extended (that is, the first spring 12 is still in a slightly compressed state, and the second spring 18 is also in a slightly compressed state), ensuring the smoothness of the force when the handle 11 is pulled, avoiding sudden force, and improving the operation experience.

[0047] Another optional embodiment of the present invention discloses a server fan module, including a front window assembly 1, a fan body 2, and a rear window assembly 5 connected and installed sequentially from front to back. The front window assembly 1 includes a handle 11, a pull member 13, a locking rod 15, and a frame-shaped front window panel 14. The front window panel 14 is provided with a horizontal mounting bracket 144. The mounting bracket 144 is T-shaped and has a shell structure that is convex at the front and open at the rear. The pull member 13 includes a pull shaft 131 and a wedge 132 connected at the front and rear. A pull shaft guide hole 149 is provided in the middle of the front side of the mounting bracket 144 for the pull shaft 131 to slide through. The front end of the 31 is connected to the handle 11 by connecting screws 17; the locking rod 15 is slidably installed in the mounting bracket 144, and the right end of the locking rod 15 is elastically supported by a second spring 18, the left end of the locking rod 15 is provided with a locking block 151, and the left side of the front window panel 14 is provided with a through hole 146 for the locking block 151 to slide out; the middle of the locking rod 15 is provided with a slot 154 in the front-rear direction, the right rear edge of the slot 154 is provided with an inclined locking rod guide surface 152, and the right front edge of the wedge 132 is provided with a wedge pressing surface 135 that can fit with the locking rod guide surface 152 and slide against the locking rod guide surface 152. Figure 6 As shown, the cross-section of the pull shaft guide hole 149 is non-circular. The pull shaft 131 is adapted to the shape of the pull shaft guide hole 149. The non-circular pull shaft guide hole 149 guides the pull shaft 131 axially and restricts the circumferential rotation of the pull shaft 131. This effectively ensures that the handle 11 is always aligned with the mounting bracket 144 (front and back coincide), effectively preventing the handle 11 from rotating arbitrarily, ensuring the convenience and reliability of use, and preventing the handle 11 from blocking the heat dissipation airflow and affecting the heat dissipation effect.

[0048] Furthermore, such as Figure 6 As shown, the pull shaft guide hole 149 has a D-shaped cross-section, and the cylindrical pull shaft 131 has a pull shaft positioning plane 133 on its side, which is adapted to the D-shaped pull shaft guide hole 149. The pull shaft 131 with the pull shaft positioning plane 133 is guided back and forth by the D-shaped pull shaft guide hole 149, and the circumferential rotation of the pull shaft 131 is restricted, which can effectively prevent the handle 11 from rotating.

[0049] In addition, the cross-sectional shape of the pull shaft guide hole 149 is not limited to D-shape. It can be a conventional shape such as triangle or square, or an irregular shape. There is no specific restriction on the shape of the pull shaft guide hole 149, as long as it can restrict the circumferential rotation of the pull shaft 131.

[0050] Another optional embodiment of the application discloses a server fan module, comprising front window assembly 1, fan body 2 and rear window assembly 5 connected and installed in sequence from front to back, the front window assembly 1 comprises handle 11, pulling member 13, locking rod 15 and frame-shaped front window panel 14; the front window panel 14 is provided with transverse mounting bracket 144, the mounting bracket 144 is in the form of T and is in the form of a shell structure with a front convex and a rear opening, the pulling member 13 comprises front and rear connecting pulling shaft 131 and wedge block 132; the mounting bracket 144 is provided with pulling shaft guide hole 149 for the front and rear sliding of pulling shaft 131, the front end of the pulling shaft 131 is connected and installed with the handle 11 through connecting screw 17; the locking rod 15 is slidably installed in the mounting bracket 144, the right end of the locking rod 15 is provided with second spring 18, the left end of the locking rod 15 is provided with clamping block 151, the left side of the front window panel 14 is provided with through hole 146 for the sliding of the clamping block 151; the middle part of the locking rod 15 is provided with front and rear direction slot 154, the right rear edge of the slot 154 is provided with inclined locking rod guide surface 152, the right front edge of the wedge block 132 is provided with wedge block pressing surface 135 which can be combined with the locking rod guide surface 152 and slide and press the locking rod guide surface 152; the cross section of the pulling shaft guide hole 149 is non-circular, the shape of the pulling shaft 131 is matched with the shape of the pulling shaft guide hole 149. As shown in Figure 4 、 6 the front end of the pulling shaft 131 is provided with two opposite pulling shaft positioning notches 134, the rear side of the handle 11 is provided with pulling shaft positioning groove 111, the pulling shaft positioning groove 111 is provided with pulling shaft positioning protrusion 112 which can be combined and positioned with the pulling shaft positioning notches 134. The front end of the pulling shaft 131 is combined with the pulling shaft positioning groove 111, the pulling shaft positioning protrusion 112 is combined and positioned with the pulling shaft positioning notches 134, and the front end of the pulling shaft 131 is screwed and installed with the handle 11 through connecting screw 17, so that the connection between the handle 11 and the pulling shaft 131 is firm, the handle 11 and the pulling shaft 131 are convenient to disassemble and assemble, and the positioning is reliable.

[0051] As shown in Figure 4 the middle part of the front side of the mounting bracket 144 is provided with V-shaped handle positioning groove 145, the rear side of the handle 11 is provided with V-shaped handle positioning protrusion 113 which can be combined with the handle positioning groove 145. The V-shaped handle positioning protrusion 113 is combined and guided with the V-shaped handle positioning groove 145, which can ensure the smoothness and reliability of the reset of the handle 11 under the condition of removing the pulling force, ensure that the handle 11 is always consistent with the direction of the mounting bracket 144 (coincide front and rear), and avoid the blocking of the handle 11 to the heat dissipation air duct to affect the heat dissipation effect.

[0052] As shown in Figure 9As shown, the mounting rack 144 is provided with a boss 147 capable of limiting the forward movement limit position of the wedge block 132. The boss 147 is in the form of an annular boss structure, and a positioning and clamping space for the front end of the first spring 12 is formed between the boss 147 and the pulling shaft 131, effectively ensuring the reliability of the action of the first spring 12. By abutting and limiting the wedge block 132 through the boss 147, excessive forward pulling of the pulling member 13 (i.e. excessive right movement of the locking rod 15) is effectively avoided, thereby avoiding excessive compression of the first spring 12 (the second spring 18), and achieving protection of the first spring 12 (the second spring 18).
