[0078] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0079] In order to enable those skilled in the art to better understand the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0080] It should be noted that the directional terms such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0081] Referring to FIG. 1 , the fan module provided in an embodiment of the present disclosure includes a mounting assembly 100 and a fan module 200 .

[0082] Among them, the mounting component 100 is used to install the fan module 200, the mounting component 100 is provided with a clamping portion, the fan module 200 includes a fan seat 210 and a rotating clamping member 220, the fan seat 210 is detachably installed on the mounting component 100, the fan seat 210 is used to install the fan body 230, the rotating clamping member 220 is connected to the fan seat 210, and the rotating clamping member 220 is used to rotate relative to the mounting component 100 to achieve clamping cooperation with the clamping portion.

[0083] In this way, when the rotating engaging member 220 is rotated to engage with the engaging portion, the fan module 200 can be fixed to the installation assembly 100 , and when the rotating engaging member 220 is disengaged from the engaging portion, the fan module 200 can be removed from the installation assembly 100 .

[0084] It can be seen that during installation, the fan seat 210 is first installed on the mounting assembly 100, and then the rotating clamping member 220 is rotated to engage with the clamping portion, so that the fan module 200 can be fixed to the mounting assembly 100; during disassembly, the rotating clamping member 220 is first rotated to disengage from the clamping portion, and then the fan seat 210 is separated from the mounting assembly 100, so that the fan module 200 can be removed from the mounting assembly 100.

[0085] With the above-mentioned fan module, since the fan module 200 and the mounting assembly 100 are assembled by snap-fitting, when installing and disassembling the fan module 200, tool-free installation and disassembly can be achieved when the hand operation space for installation and disassembly is limited, which is not only convenient to operate but also can achieve quick installation and disassembly; at the same time, by improving the installation and disassembly method of the fan module 200 and the mounting assembly 100, the use of brackets and a large number of detachable connectors 160 (screws, rivets, etc.) for connection can be avoided, which can reduce the types and quantities of parts required for installation and disassembly, reduce the installation and disassembly process, thereby reducing the labor intensity of the operator and reducing production costs.

[0086] Please refer to FIG. 7 and FIG. 20 . The fan base 210 includes a first base body 211 and a second base body 212 . The first base body 211 and the second base body 212 can be connected by a snap-fit ​​method.

[0087] Please refer to Figures 8, 9 and 21 together. The first base body 211 is provided with a first buckle 2111 and a first slot 2112, and the second base body 212 is provided with a second buckle 2121 and a second slot 2122. During installation, the first buckle 2111 on the first base body 211 is snap-fitted with the second slot 2122 on the second base body 212, and the second buckle 2121 on the second base body 212 is snap-fitted with the first slot 2112 on the first base body 211, so that the first base body 211 and the second base body 212 are docked and installed to form the fan base 210.

[0088] In order to facilitate the installation of the fan body 230, the first base 211 and the second base 212 are both provided with an installation structure 213 for installing the fan body 230. The installation structure 213 can be an installation slot or an installation hole 12125 pin.

[0089] In the first fan module, the first seat body 211 and the second seat body 212 are both configured as semi-cylindrical structures, and the fan seat 210 with a cylindrical structure is formed by docking the two semi-cylindrical seat bodies, as shown in Figures 7, 8 and 9.

[0090] Among them, four installation slots are arranged on the inner walls of both the first seat body 211 and the second seat body 212, which are spaced apart along the circumferential direction. The four installation slots are respectively used to engage with the four corners of the rectangular structure of the fan body 230 to limit the freedom of the fan body 230 in the circumferential direction. Furthermore, when the first seat body 211 and the second seat body 212 are docked, the freedom of the fan body 230 in the axial direction can be limited, thereby ensuring the stability and reliability of the installation of the fan body 230 in the fan seat 210.

[0091] In the second fan module, the first seat body 211 and the second seat body 212 are both configured as a semi-axle frame structure, and the fan seat 210 of the axis frame structure is formed by docking the two semi-axle frames, as shown in Figures 20 and 21.

[0092] Among them, the semi-axis frame includes a plate body, and a clip and a slot are respectively provided on both sides of the plate body. The clip is fixed to the plate body through a connecting shaft, and the length of the connecting shaft is adapted to the length of the fan body 230. During installation, the first clip 2111 and the first slot 2112 on one of the semi-axis frames are respectively engaged with the second slot 2122 and the second clip 2121 on the other semi-axis frame, so that the two semi-axis frames are docked and installed to form a fan seat 210.

[0093] In order to facilitate the installation of the fan body 230, four mounting holes 12125 pins are provided on the inner wall of the plate body of the two half-axis frames. During installation, after aligning the mounting holes 12125 pins of the two half-axis frames with the fan body 230, the two half-axis frames are docked and installed, and the fan body 230 can be installed on the fan base 210.

[0094] It can be seen that compared with the fan seat 210 with a cylindrical structure, the fan seat 210 with an axis frame structure has a simpler structure and is lighter in weight, and does not fully wrap the fan body 230. This is beneficial for heat dissipation of the fan body 230 during operation and ensures the stability of the fan operation.

[0095] To facilitate installation of the fan module 200 , the installation assembly 100 includes a mounting base 110 and a movable member 120 movably mounted on the mounting base 110 .

[0096] The mounting base 110 includes a bottom plate 111. A space is provided above the bottom plate 111 for accommodating the movable member 120. The bottom plate 111 is provided with fixing holes 1111 for securing the mounting base 110 to the chassis 10. These fixing holes 1111 can be screw holes. When installing the mounting base 110, the screw holes on the mounting base 110 are aligned with the studs on the chassis 10, and the screws are inserted and tightened to secure the mounting base 110 to the chassis 10.

[0097] Please refer to FIG. 2 . In the first fan module, the movable member 120 is a rotation control member 121 . The rotation control member 121 is rotatably mounted on the mounting base 110 . The engaging portion is provided on the rotation control member 121 . The fan base 210 is rotatably mounted on the mounting base 110 .

[0098] In this way, by rotating the locking member 220 to engage with the locking portion, the fan module 200 is fixed to the installation component 100, and by rotating the control member 121 to rotate the locking member 220 to disengage the locking portion, the fan module 200 is disconnected from the installation component 100.

[0099] In this embodiment, the rotating clamping member 220 is a U-shaped structure. The rotating clamping member 220 can not only fix the fan module 200, but also serve as a handle. After the rotating clamping member 220 is disengaged from the clamping portion, the fan module 200 can be picked up by rotating the clamping member 220, thereby removing the fan module 200 from the mounting base 110.

[0100] Please refer to Figures 3 and 4 together. In order to facilitate the rotational connection of the fan base 210 to the mounting base 110, the mounting base 110 also includes two oppositely arranged support arms 112, and the bottom plate 111 is connected between the two support arms 112. Both support arms 112 are provided with a rotation mounting groove 1121 for allowing the fan module 200 to be vertically installed into the mounting base 110. A rotation connection end 214 extends from both ends of the fan base 210 along the axial direction. The two rotation connection ends 214 can be rotatably installed in the corresponding rotation mounting groove 1121 so that the rotation engaging member 220 drives the fan base 210 to rotate.

[0101] It should be noted that the rotating connection ends 214 at both ends of the fan base 210 are provided with anti-rotation structures 2141, and the two ends of the rotating clamping member 220 are respectively provided with anti-rotation grooves that engage with the corresponding anti-rotation structures 2141. During installation, the anti-rotation grooves at both ends of the rotating clamping member 220 are first docked and engaged with the anti-rotation structures 2141 on the two rotating connection ends 214, and then the connection is locked by screws. In this way, the rotating clamping member 220 can be fixedly connected to the fan base 210. At the same time, by pushing the rotating clamping member 220, the fan base 210 can be driven to rotate relative to the mounting base 110.

[0102] In order to facilitate the rotational connection of the rotation control member 121 to the mounting base 110, a first axial hole 1122 is provided on the support arm 112 and the base plate 111 on one side, and a second axial hole 1123 is provided on the support arm 112 and the base plate 111 on the other side. The rotation control member 121 is provided with a third axial hole 12121 corresponding to each first axial hole 1122 and a fourth axial hole 12122 corresponding to each second axial hole 1123; at the same time, the fan module also includes a first rotating shaft 140 and a second rotating shaft 150, the first rotating shaft 140 passes through the corresponding first axial hole 1122 and the third axial hole 12121, and the second rotating shaft 150 passes through the corresponding second axial hole 1123 and the fourth axial hole 12122, so that the rotation control member 121 can be rotatably connected between the two support arms 112.

[0103] Of course, according to actual needs, the above-mentioned rotation control member 121 can be an L-shaped structure. When disassembling, the rotation control member 121 can be disengaged from the rotation engaging member 220 by simply pressing the rotation control member 121. Based on this, an avoidance groove for avoiding the rotation control member 121 is provided on the bottom plate 111. Under the action of pressing force, one end of the rotation control member 121 can be rotated into the avoidance groove of the bottom plate 111. At this time, the engaging portion on the rotation control member 121 can be disengaged from the rotation engaging member 220.

[0104] On the basis of the above, the fan module also includes a first elastic member 300 and a fixed plate 400. The fixed plate 400 is connected to the mounting base 110, and the fan base 210 is slidingly engaged with the fixed plate 400. The two ends of the first elastic member 300 are respectively connected to the fixed plate 400 and the fan base 210. The first elastic member 300 is configured to generate elastic deformation when the rotating clamping member 220 is engaged with the clamping portion, so that the rotating clamping member 220 has a tendency to rotate to a vertical position.

[0105] The first elastic member 300 is an elastic ring, comprising a circular elastic body 310 and connecting portions 320 disposed at either end of the circular elastic body 310. The circular elastic body 310 and the two connecting portions 320 form a closed elastic ring. Furthermore, to facilitate securing the elastic ring, a first hook 420 is provided on the fixing plate 400, and a second hook 215 is provided on the fan base 210. The connecting portions 320 at either end are respectively connected to the first hook 420 and the second hook 215, thereby securing the elastic ring to the fixing plate 400 and the fan base 210.

[0106] Of course, the second hook 215 on the fan base 210 can be formed by docking the first half hook on the first base body 211 with the second half hook on the second base body 212 .

[0107] In this way, since the fixing plate 400 is fixed to the mounting base 110, when the rotating engaging member 220 is pulled to engage with the engaging portion on the rotating control member 121, the elastic ring is stretched to a predetermined length because one end of the elastic ring is fixed to the first hook 420 of the fixing plate 400 and the other end is fixed to the fan base 210, which rotates with the rotating engaging member 220. The elastic ring is deformed by the stretching and generates an elastic force, which tends to reset the rotating engaging member 220 (return to its initial position before being pulled). After the rotating engaging member 220 is reset, the fan module 200 can be removed.

[0108] The fixing piece 400 can be installed simultaneously with the fan base 210 . Specifically, the fixing piece 400 is placed between two semi-cylindrical base bodies, and then the two base bodies are connected to form the fan base 210 including the fixing piece 400 .

[0109] Please refer to Figure 10. The fixing plate 400 includes an arc body 410, and a sliding portion 411 extends from both sides of the arc body 410 along the width direction; the first base 211 and the second base 212 are provided with oppositely arranged sliding grooves 216, and the sliding portion 411 slides in conjunction with the sliding groove 216 to enable the fan base 210 to rotate relative to the fixing plate 400.

[0110] That is to say, in the process of pulling the rotating engaging member 220 to engage the rotating engaging member 220 with the engaging portion on the rotating control member 121, the fixing plate 400 is fixed to the mounting base 110, and the fan base 210 can be rotated relative to the fixing plate 400 until the rotating engaging member 220 is completely engaged with the engaging portion on the rotating control member 121, thereby realizing the installation of the fan module 200.

[0111] In order to facilitate the fixed connection between the fixing plate 400 and the mounting seat 110, a boss 1112 is provided on the base plate 111, and an alignment hole 1113 is provided on the boss 1112; accordingly, an alignment pin 430 is provided on the fixing plate 400, and the alignment pin 430 is plugged into the alignment hole 1113 to fix the fixing plate 400 to the base plate 111.

[0112] It should be noted that when the fan module 200 is placed into the mounting base 110 and the alignment pin 430 is plugged into the alignment hole 1113, the rotating connection end 214 contacts and abuts against the inner wall of the corresponding rotating mounting groove 1121. That is to say, after confirming that the alignment pin 430 of the fixing plate 400 is plugged into the alignment hole 1113 of the mounting base 110, it means that the fan base 210 has been installed in place.

[0113] Based on this, the alignment pin 430 is provided with an annular protrusion, and an elastic buckle is provided in the alignment hole 1113, and the elastic buckle is provided with a buckle position. When the alignment pin 430 is inserted into the alignment hole 1113, the elastic buckle undergoes elastic deformation to allow the annular protrusion to pass over the buckle position. The elastic buckle is reset after the annular protrusion passes over the buckle position, so that the alignment pin 430 is locked in the alignment hole 1113, and can provide the user with a sound prompt that the installation is in place.

[0114] In other words, when the user hears the "click" sound prompt, it indicates that the alignment pin 430 of the fixing plate 400 and the alignment hole 1113 of the mounting seat 110 have been inserted into place.

[0115] In order to facilitate the locking of the alignment pin 430 of the fixing plate 400 in the alignment hole 1113 of the mounting seat 110, the annular protrusion is provided with a first locking surface and a first inclined surface in sequence along the plugging direction of the alignment pin 430, and the snap position is provided with a second inclined surface and a second locking surface in sequence along the socket direction of the alignment hole 1113. When the alignment pin 430 is inserted into the alignment hole 1113, the elastic snap position is deformed under the cooperation of the second inclined surface and the first inclined surface to allow the annular protrusion to pass over the snap position. The elastic snap position is reset after the annular protrusion passes over the snap position, so that the second locking surface is against the first locking surface, thereby locking the alignment pin 430 in the alignment hole 1113.

[0116] Please refer to FIG. 5 and FIG. 6 together, and the structure of the rotation control member 121 will be described in detail below.

[0117] The rotation control member 121 includes a longitudinal clamping body 1211, and a clamping portion is provided at the top of the longitudinal clamping body 1211, which is specifically a hook 131. The hook 131 is provided with a guide slope 1311 and a first clamping surface 1312 in sequence along the clamping direction of the rotation clamping member 220. The rotation clamping member 220 is provided with a second clamping surface 221. The rotation clamping member 220 passes over the hook 131 via the guide slope 1311 so that the second clamping surface 221 is abutted against the first clamping surface 1312, thereby realizing that the rotation clamping member 220 is locked to the rotation control member 121.

[0118] With the above arrangement, the engaging manner of the rotating engaging member 220 and the rotating control member 121 is easy to operate, saves time and effort, and is conducive to improving the installation efficiency of the fan module 200 .

[0119] Furthermore, the rotation control member 121 also includes a horizontal operating body 1212, which is perpendicular to the longitudinal clamping body 1211. At the same time, the horizontal operating body 1212 and the longitudinal clamping body 1211 are connected through an inner arc transition structure 1213. The thickness of the horizontal operating body 1212 in the area covered by the inner arc transition structure 1213 is greater than the thickness of the horizontal operating body 1212 in the area not covered by the inner arc transition structure 1213. This can greatly improve the overall strength of the rotation control member 121 and increase the service life of the rotation control member 121.

[0120] At the same time, the horizontal operating body 1212 is provided with a limit groove 12123 located on the side of the inner arc transition structure 1213 away from the longitudinal clamping body 1211, and the fan seat 210 is provided with a limit pin 217. The limit pin 217 is configured to be embedded in the limit groove 12123 when the rotating clamping member 220 is engaged with the hook 131, so that the fan module 200 is fixed to the installation assembly 100.

[0121] In this way, when installing the fan module 200, on the one hand, the rotating locking member 220 is engaged with the locking portion on the rotating control member 121, and on the other hand, the limiting pin 217 on the fan seat 210 is engaged with the limiting groove 12123 on the rotating control member 121, so as to ensure the stability and reliability of the installation of the fan module 200 and the installation assembly 100.

[0122] In addition, the part of the horizontal operating body 1212 extending out of the fan seat 210 is provided with a pressing area 12124, and the pressing area 12124 is located on the side of the limiting groove 12123 away from the longitudinal clamping body 1211. The rotation control member 121 is configured to rotate relative to the mounting seat 110 after pressing the pressing area 12124, so that the second clamping surface 221 is disengaged from the first clamping surface 1312 and the limiting pin 217 is disengaged from the limiting groove 12123, thereby realizing the disconnection of the fan module 200 from the mounting assembly 100.

[0123] In this way, when disassembling the fan module 200, it is only necessary to press the pressing area 12124 of the rotating control member 121 to disengage the second clamping surface 221 of the rotating clamping member 220 from the first clamping surface 1312 of the hook 131 and the limiting pin 217 on the fan seat 210 from the limiting groove 12123 on the rotating control member 121, so that the fan module 200 can be easily disconnected from the installation assembly 100.

[0124] It should be noted that in order to ensure the stability of the embedding, the number of the limiting grooves 12123 on the above-mentioned horizontal operating body 1212 is two. At the same time, the rotating control part 121 is provided with a hollow structure 12126, which is located between the two limiting grooves 12123 or the inner arc transition structure 1213. The hollow structure 12126 is used to accommodate the boss 1112.

[0125] In order to ensure the strength of the rotation control member 121, the ratio of the width of the hollow structure 12126 to the width of the horizontal operating portion is between 1:3 and 1:6, and the ratio of the length of the hollow structure 12126 to the length of the horizontal operating portion is greater than 1:2.

[0126] In order to facilitate the resetting of the rotation control member 121, the fan module also includes a second elastic member 500, which is specifically a compression spring. The horizontal operating body 1212 is provided with a mounting hole 12125 on the side away from the pressing area 12124. One end of the second elastic member 500 abuts against the mounting hole 12125. The second elastic member 500 is configured to generate elastic deformation when the pressing area 12124 is pressed, so that the longitudinal clamping body 1211 has a tendency to rotate to a vertical position.

[0127] When removing the fan module 200, it is only necessary to press the pressing area 12124 of the rotating control member 121. After pressing, since the two ends of the compression spring abut against the mounting hole 12125 at the bottom of the horizontal operating body 1212 and the pin on the chassis 10, the spring can provide elastic force to the pressing area 12124 of the rotating control member 121 after compression deformation. Under the action of this elastic force, the rotating control member 121 has a tendency to rotate in the opposite direction until it is reset. At this time, as long as the pressing area 12124 is released, the rotating control member 121 can automatically reset.

[0128] In summary, the installation and removal process of the first type of fan module 200 can be as follows:

[0129] Please refer to FIG. 11 . Assemble the mounting assembly 100. Screws are inserted through the screw holes of the mounting base 110 and then screwed onto the studs of the chassis 10 to secure the mounting base 110 to the chassis 10. The rotation control member 121 is placed into the mounting base 110. The compression spring is assembled between the pin of the chassis 10 and the mounting hole 12125 on the back of the rotation control member 121. The first rotating shaft 140 is inserted through the corresponding first and third shaft holes 1122 and 12121, and the second rotating shaft 150 is inserted through the corresponding second and fourth shaft holes 1123 and 12122, to rotatably mount the rotation control member 121 on the mounting base 110.

[0130] Please refer to FIG. 12 for the assembly of the fan module 200. After placing the fan body 230 and the fixing plate 400 between the two semi-cylindrical base bodies, align the clips on the two base bodies with the slots and engage them to complete the assembly of the fan base 210. Insert the elastic ring into the hooks on the fan base 210 and the fixing plate 400 to complete the assembly of the elastic ring. Align the rotating engaging member 220 with the anti-rotation structure 2141 of the fan base 210 and tighten the screws on both sides to complete the assembly of the rotating engaging member 220.

[0131] Please refer to FIG. 13 . Install the fan module 200 on the mounting assembly 100 by placing the fan base 210 into the rotatable mounting slot 1121 of the mounting base 110 . After confirming that the alignment pin 430 of the fixing plate 400 is properly engaged with the alignment hole 1113 of the mounting base 110 , pull the rotatable engaging member 220 to rotate the fan base 210 until the rotatable engaging member 220 engages with the engaging portion of the rotatable control member 121 and the limiting pin 217 of the fan base 210 engages with the limiting slot 12123 of the rotatable control member 121 . This completes the installation of the fan module 200 on the mounting assembly 100 .

[0132] Please refer to Figure 14 to remove the fan module 200 from the mounting assembly 100: press the pressing area 12124 of the rotation control member 121 to disengage the rotation engaging member 220 from the engaging portion of the rotation control member 121 and the limiting pin 217 of the fan base 210 from the limiting groove 12123 of the rotation control member 121. The elastic ring contracts to reset the fan module 200, and the spring extends to reset the rotation control member 121. The fan module 200 is then unlocked and can be taken out.

[0133] In the second fan module, please refer to FIG. 15 , the movable member 120 is a translation control member 122 , which is movably connected to the mounting base 110 . The clamping portion is provided on the mounting base 110 , and the fan base 210 is mounted on the translation control member 122 .

[0134] In this way, the translation control member 122 can be configured as follows: when the rotating engaging member 220 is rotated to a position where it is engaged with the engaging portion, the translation control member 122 is shifted to engage the rotating engaging member 220 with the engaging portion, so that the fan module 200 can be fixed to the mounting assembly 100; when the fan module 200 is removed, the translation control member 122 drives the rotating engaging member 220 to disengage from the engaging portion, so that the fan module 200 is disconnected from the mounting assembly 100.

[0135] Please refer to Figure 19 as well. The translation control member 122 can be a translation seat, which includes a translation plate 1221 and a retaining structure 1222 provided on the translation plate 1221. The fan seat 210 is installed on the translation plate 1221 and is limited by the retaining structure 1222.

[0136] At the same time, in order to facilitate the movable connection between the moving seat and the mounting seat 110, a movable hole 12211 is provided on the moving plate 1221, and a connecting piece 160 is provided on the mounting seat 110, which is located in the movable hole 12211. The movable hole 12211 moves relative to the connecting piece 160, so that the moving plate 1221 moves relative to the mounting seat 110.

[0137] Please refer to Figure 16. The above-mentioned connecting member 160 can be an I-nail. Correspondingly, the movable hole 12211 is a hole position for the I-nail to be connected, and the movable hole 12211 is a gourd-shaped hole position. The mounting base 110 is provided with a through hole for the I-nail to pass through. During installation, first align the screw hole on the mounting base 110 with the stud on the chassis 10, then insert and tighten the screw. Note that the I-nail must also pass through the through hole on the mounting base 110 at this time. In this way, the mounting base 110 can be fixed to the chassis 10. Afterwards, align the large hole of the gourd-shaped hole position of the translation base with the I-nail, insert it and push it inward.

[0138] On the basis of the above, the fan module also includes a third elastic member 170, which is a compression spring. In order to facilitate the installation of the third elastic member 170, the mounting seat 110 is provided with a first card point 113, and the translation control member 122 is provided with a second card point 1223. The two ends of the third elastic member 170 are respectively connected to the first card point 113 and the second card point 1223. The third elastic member 170 is used to provide elastic force to the translation control member 122 so that the translation control member 122 has a tendency to move away from the first card point 113.

[0139] In this way, after aligning the large hole of the gourd-shaped hole of the translation control component 122 with the I-nail and inserting it, push the translation control component 122 inward so that the I-nail is located in the small hole of the gourd-shaped hole of the translation control component 122, and then put the third elastic component 170 between the translation control component 122 and the mounting seat 110, and use the elastic force of the third elastic component 170 to maintain the position of the translation control component 122 in the mounting seat 110, so that the assembly of the translation control component 122 and the mounting seat 110 can be completed.

[0140] Please refer to Figures 22 and 23 together. There are two rotating clamps 220, and both rotating clamps 220 are provided with a snap point 222 and a snap groove 223. The snap point 222 of one rotating clamp 220 is snap-connected with the snap groove 223 of the other rotating clamp 220 to close the two rotating clamps 220. After closing, the two rotating clamps 220 are combined to form a handle structure, which is convenient for lifting and taking out the fan module 200.

[0141] Of course, a handle area 226 may be further provided in the middle area of ​​the handle structure to facilitate grabbing the handle area 226 and taking out the fan module 200 .

[0142] In order to facilitate the connection between the rotating clamping member 220 and the fan seat 210, the ends of the two semi-axis frame structures of the fan seat 210 are provided with locking shafts 2113. Correspondingly, both ends of the rotating clamping member 220 are provided with locking holes 227 that cooperate with the corresponding locking shafts 2113. After aligning the locking holes 227 on the rotating clamping member 220 with the locking shafts 2113 of the semi-axis frame structure seat body, tighten the screws to complete the assembly of the rotating clamping member 220 and the fan seat 210.

[0143] Please refer to Figures 17 and 18 together. The mounting base 110 also includes two groups of support rods 114 (specifically four support rods 114, and the four support rods 114 are respectively located at the four corners of the rectangular base plate 111) provided on the base plate 111. The clamping portion includes a clamping protrusion 132 respectively located on each support rod 114, and the two rotating clamping members 220 are both provided with a clamping groove 224 corresponding to the clamping protrusion 132. In this way, one of the rotating clamping members 220 is turned to one side and clamped and fixed with the clamping protrusion 132 on one group of support rods 114, and the other rotating clamping member 220 is turned to the other side and clamped and fixed with the clamping protrusion 132 on the other group of support rods 114. In this way, the fan module 200 can be installed on the mounting assembly 100.

[0144] It should be noted that after the fan base 210 is placed into the translation control member 122 through the two closed rotating clamps 220, the two rotating clamps 220 are pried apart in the directions of both sides until the two rotating clamps 220 contact the engaging protrusions 132 on the two sets of support rods 114. The translation control member 122 is then subjected to force to compress the third elastic member 170 to make way, thereby causing the engaging protrusions 132 on the two sets of support rods 114 to be engaged in the corresponding engaging grooves 224. Under the elastic force of the third elastic member 170, the translation control member 122 returns to its position to complete the assembly of the fan module 200.

[0145] To this end, the fan module also includes a fourth elastic member 600, which is an elastic ring. The two rotating engaging members 220 are both provided with a third hook 225. The two ends of the fourth elastic member 600 are respectively sleeved on the third hooks 225 on the two rotating engaging members 220. The fourth elastic member 600 is configured to generate elastic deformation when the two rotating engaging members 220 are both engaged with the mounting seat 110, so that the two rotating engaging members 220 have a tendency to close.

[0146] It can be understood that when the two rotating clamps 220 are in a closed state, the fourth elastic member 600 is in an original state, and when the two rotating clamps 220 are in an open state, the fourth elastic member 600 is stretched. At this time, the fourth elastic member 600 can provide elastic force to the two rotating clamps 220 so that the two rotating clamps 220 have a tendency to rotate in the closing direction.

[0147] In addition, in order to prevent the rotating clamping member 220 from turning too far, a stop reinforcement rib 115 can be provided on each support rod 114. The height of the stop reinforcement rib 115 is lower than the corresponding support rod 114. When the clamping grooves 224 of the two rotating clamping members 220 are correspondingly engaged with the clamping protrusions 132 on the two groups of support rods 114, the rotating clamping member 220 just contacts and abuts against the stop reinforcement rib 115, thereby preventing the rotating clamping member 220 from rotating excessively.

[0148] In summary, the installation and removal process of the second type of fan module 200 can be as follows:

[0149] Please refer to Figure 24 to assemble the mounting assembly 100: first align the screw holes on the mounting base 110 with the studs on the chassis 10, then insert and tighten the screws. Note that the I-nail must also pass through the through hole on the mounting base 110 at this time, so that the mounting base 110 can be fixed to the chassis 10; then, align the large hole of the gourd-shaped hole of the translation control member 122 with the I-nail, then insert and push the translation control member 122 inward; then, insert the third elastic member 170 between the translation control member 122 and the mounting base 110, and use the elastic force of the third elastic member 170 to maintain the position of the translation control member 122 in the mounting base 110, so that the assembly of the translation control member 122 and the mounting base 110 is completed.

[0150] Please refer to FIG. 25 to assemble the fan module 200. After aligning the mounting holes 12125 of the two semi-axle frame structures with the fan body 230, align the clips on the two seats with the slots and engage them to complete the assembly of the fan seat 210. After aligning the locking hole 227 on the rotating engaging member 220 with the locking axis 2113 of the semi-axle frame structure, tighten the screws to complete the assembly of the rotating engaging member 220 and the fan seat 210. Attach the two ends of the fourth elastic member 600 to the third hooks 225 on the two rotating engaging members 220, respectively, to complete the assembly of the fan module 200.

[0151] Please refer to Figure 26 to install the fan module 200 on the installation assembly 100: After placing the fan base 210 into the translation control member 122 through the two closed rotating clamps 220, the two rotating clamps 220 are pried apart in the directions of both sides, and the fourth elastic member 600 is forced to open until the two rotating clamps 220 respectively contact the engaging protrusions 132 on the two groups of support rods 114. The translation control member 122 is then forced to compress the third elastic member 170 to make way, so that the engaging protrusions 132 on the two groups of support rods 114 are engaged in the corresponding engaging grooves 224. Under the elastic force of the third elastic member 170, the translation control member 122 returns to its position to complete the assembly of the fan module 200.

[0152] Please refer to Figure 27 to remove the fan module 200 from the mounting assembly 100: apply thrust to the fan base 210, and the fan base 210 drives the translation control member 122 to squeeze the third elastic member 170, so that the locking protrusion 132 on the mounting base 110 disengages from the locking groove 224 on the corresponding rotating locking member 220. Then, the two rotating locking members 220 rotate in the closing direction under the elastic force of the fourth elastic member 600 until the corresponding locking points 222 and locking grooves 223 on the two rotating locking members 220 are locked and connected. Then, the handle area 226 of the two rotating locking members 220 in the closed state can be grabbed to take out the fan module 200.

[0153] Please refer to FIG. 28 . In the first or second fan module, a locking state detection component 700 , a locking state prompt component 800 and a control component 900 may also be provided.

[0154] Among them, the engagement state detection component 700 is installed on the engagement part or the rotating engagement part 220, and the engagement state detection component 700 is used to detect whether the rotating engagement part 220 and the engagement part are engaged in place; the engagement state prompt component 800 is installed on the installation component 100, and the engagement state prompt component 800 is used to provide feedback to the user when the rotating engagement part 220 and the engagement part are engaged; the control component 900 is communicated with the engagement state detection component 700 and the engagement state prompt component 800, and the control component 900 is used to receive the feedback signal of the engagement state detection component 700 and send control instructions to the engagement state prompt component 800.

[0155] It should be noted that the above-mentioned engagement state detection component 700 can be a force sensor / stress strain gauge, and the force sensor is used to detect the force after the rotating engagement member 220 and the engagement portion are engaged. When the force after the rotating engagement member 220 or the engagement portion is engaged reaches a preset condition, it indicates that the two are engaged in place, and the fan module 200 is now stably installed; the above-mentioned engagement state prompt component 800 can be a sound prompter or a text prompter. When receiving the signal feedback from the engagement state detection component 700 about the engagement of the rotating engagement member 220 and the engagement portion, the control component 900 sends a control instruction to the engagement state prompt component 800, so that the engagement state prompt component 800 issues a sound prompt or a text prompt. After receiving the prompt signal, the on-site operator can conveniently enter the subsequent assembly process.

[0156] Such a setting can automatically identify the engagement status of the rotating engaging member 220 and the engaging portion, and feed back the engagement status signal to the operator, which can effectively avoid the situation where the engagement between the rotating engaging member 220 and the engaging portion fails due to operational errors, and helps to ensure the success rate and stability of the engagement between the rotating engaging member 220 and the engaging portion. At the same time, the assembly efficiency can be effectively improved.

[0157] The above two fan modules are easy to install and have low labor costs. They not only increase the convenience of system maintenance and have high versatility, but also increase product competitiveness. They do not require metal brackets, fan rivets, etc., thus saving costs.

[0158] The present disclosure provides a server, including a chassis 10 and a fan module as described in the above specific embodiment. The fan module is installed in the chassis 10 to dissipate heat from the working components in the chassis 10.
