[0091] Multiple embodiments of the present invention will be disclosed below with reference to the accompanying drawings. For the sake of clear illustration, many practical details will be described together in the following description. However, it should be understood that these practical details are not used to limit the present invention. That is to say, in one embodiment of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and elements will be shown in a simple schematic manner in the drawings.

[0092] Figure 1 Is a perspective view of an electronic device 10 according to an embodiment of the present invention. Figure 2 Is Figure 1 A partial exploded view of the electronic device 10. As Figure 1 And Figure 2As shown, in this embodiment, an electronic device 10 includes a chassis 100, a circuit board 200 (such as a main board or a daughter board), and a plurality of (such as six) fan modules 300. The chassis 100 includes a housing 110 and a plurality of first snap ports 114. The housing 110 includes a bottom plate 111 and a plurality of side plates 112. These side plates 112 surround the bottom plate 111, the bottom plate 111 is adjacent to these side plates 112 respectively, and the bottom plate 111 and these side plates 112 together define an accommodation space 113. The accommodation space 113 is in a long strip shape, and the accommodation space 113 has a major axis direction (such as the X-axis, hereinafter referred to as the first direction). These first snap ports 114 are distributed on one of the side plates 112 (hereinafter referred to as the rear side plate 112A) of the housing 110 along a second direction (such as the Y-axis) orthogonal to the first direction. Each first snap port 114 penetrates the rear side plate 112A, and each first snap port 114 communicates with the accommodation space 113. The circuit board 200 is placed flat in the accommodation space 113. For example, the circuit board 200 includes a board body 210 and a plurality of first connectors 220. The board body 210 extends along the X-Y plane and is fixedly placed flat on the bottom plate 111. These first connectors 220 are arranged on a surface of the board body 210 opposite to the bottom plate 111 (hereinafter referred to as the top surface 211), and are electrically connected to the distributed circuits (not shown) on the board body 210. These fan modules 300 are arranged in sequence along the second direction (such as the Y-axis) on the circuit board 200, and are simultaneously connected to the circuit board 200 and the rear side plate 112A of the chassis 100.

[0093] Figure 3 is Figure 2 an exploded view of the electronic device 10 observed from another perspective. As Figure 2 and Figure 3 shown, in this embodiment, the chassis 100 further includes a plurality of limit ports 115. These limit ports 115 and the first snap ports 114 are arranged at intervals on the rear side plate 112A of the chassis 100. Each limit port 115 penetrates the rear side plate 112A of the chassis 100 and communicates with the accommodation space 113. Each fan module 300 also has a plurality of limit members 600. The limit members 600 are distributed at intervals on a surface of the fan module 300 facing the rear side plate 112A. Therefore, through these limit members 600, they can be respectively removably hooked into these limit ports 115, so that the fan module 300 can be limited on the rear side plate 112A of the chassis 100. In this way, each fan module 300 can be fixed on the chassis 100 and cannot move downward (such as the Z-axis).

[0094] For example, in the present embodiment, each limiting opening 115 is a gourd-shaped hole 116. The gourd-shaped hole 116 includes a large hole 116A and a small hole 116B that are connected, and the small hole 116B is located below the large hole 116A. Each limiting member 600 is a hook nail. When each hook nail moves through the large hole 116A of one of the gourd-shaped holes 116 and moves into its small hole 116B, the fan module 300 can be limited to the rear side plate 112A of the box body 110 by the hook nail being buckled in the small hole 116B of the gourd-shaped hole 116. Conversely, the fan module 300 can be detached from the rear side plate 112A of the box body 110. Thus, the fan module 300 can be disassembled and assembled on the chassis 100 without tools.

[0095] Also, Figure 4 is Figure 1 a cross-sectional view taken along line AA in. As Figure 2 and Figure 4 shown, the chassis 100 further includes a plurality of limiting seats 230. Each limiting seat 230 is L-shaped and is fixed in the accommodating space 113. For example, these limiting seats 230 are locked to the top surface 211 of the board body 210 of the circuit board 200. However, the present invention is not limited to the arrangement position of the limiting seats 230. Each fan module 300 can be directly clamped between two limiting seats 230 and the rear side plate 112A, so that the fan module 300 can be more stably fixed on the chassis 100. More specifically, the L-shaped limiting seat 230 includes a first part 231 and a second part 232, and the first part 231 and the second part 232 are adjacent to and orthogonal (or at least intersect) with each other. The first part 231 directly supports the fan module 300 and keeps the fan module 300 separated from the top surface 211 of the board body 210. One surface of the second part 232 is protruded and directly abuts against one surface of the fan module 300 relative to the rear side plate 112A. Thus, each fan module 300 can be fixed in the chassis 100 and cannot move arbitrarily along the first direction (such as the X-axis).

[0096] Figure 5 is Figure 2 an exploded view of the fan module 300 of. As Figure 2 and Figure 5 shown, in the present embodiment, each fan module 300 includes a carrier frame 310, one or more (such as 2) fan units 380, a pull rod part 400, and a second connector 500. The carrier frame 310 is simultaneously connected to the circuit board 200 and the rear side plate 112A of the chassis 100, and houses these fan units 380 therein. The pull rod part 400 is pivotally connected to the carrier frame 310. On the one hand, it serves as a limiting tenon when the fan is installed, and on the other hand, it serves as a force-applying grip when the fan is removed. The second connector 500 is located on the carrier frame 310, and the second connector 500 is detachably connected to the first connector 220 ( Figure 1 ).

[0097] More specifically, the carrier frame 310 includes a frame 320 and a second snap port 370. The frame 320 is fixed within the accommodation space 113, and the second snap port 370 is located on the frame 320. These fan units 380 are stacked within the frame 320 in a vertical direction (such as the Z-axis) and are electrically connected to the second connector 500. Thus, each fan unit 380 is electrically connected to the circuit board 200 through the second connector 500 and the first connector 220( Figure 2 ).

[0098] In this embodiment, as Figure 5 shown, the frame 320 is in the shape of a rectangular body and has a top surface 321, a bottom surface 322, a front side surface 323, a rear side surface 324, and two outer side surfaces 325. The top surface 321 and the bottom surface 322 face each other. The front side surface 323 and the rear side surface 324 face each other, and these two outer side surfaces 325 face each other, and one of the outer side surfaces 325 is adjacent to the top surface 321, the bottom surface 322, the front side surface 323, and the rear side surface 324 at the same time. The bottom surface 322 of the frame 320 faces the circuit board 200 within the chassis 100, and the second connector 500 is configured thereon. The rear side surface 324 of the frame 320 faces the rear end side plate 112A of the cabinet 110, and the above-mentioned limiting member 600 is configured thereon. However, the present invention is not limited to the shape of the frame 320. More specifically, the frame 320 further includes a cover plate 327. After the fan unit 380 is moved into the frame 320, the cover plate 327 covers the frame 320 and restricts the fan unit 380 from moving out of the frame 320. Thus, the side of the cover plate 327 facing away from the fan unit 380 serves as the above-mentioned rear side surface 324.

[0099] Each fan unit 380 has a front surface 381 and a rear surface 382 facing each other. The front surface 381 has one or more (such as 4) first positioning holes 383, and the rear surface 382 has one or more (such as 4) second positioning holes 384. The frame 320 includes a plurality of (such as 4) first through holes 330, a plurality of (such as 4) second through holes 340, a plurality of (such as 4) first fixing pins 350, and a plurality of (such as 4) second fixing pins 360. These first through holes 330 are distributed on the front side surface 323 of the frame 320 and are aligned with these first positioning holes 383, and these second through holes 340 are distributed on the front side surface 323 of the frame 320 and are aligned with these second positioning holes 384.

[0100] In this way, when each fan unit 380 is moved into the frame 320, the fan unit 380 is held within the frame 320 by inserting the first fixing pins 350 through the first through holes 330 into the first positioning holes 383 of the fan unit 380 and inserting the second fixing pins 360 through the second through holes 340 into the second positioning holes 384 of the fan unit 380( Figure 4 ).

[0101] Furthermore, the carrying frame 310 further has a recessed portion 326, and the second buckle opening 370 is formed within the recessed portion 326. The recessed portion 326 is disposed on both the top surface 321 and one of the outer side surfaces 325 of the frame 320. The recessed portion 326 is in a long and narrow shape, and the long axis direction of the recessed portion 326 is parallel to the first direction (such as the X-axis). Therefore, when the pull rod portion 400 is not in use, the pull rod portion 400 can be completely received within the recessed portion 326 without protruding from the surface of the frame 320. In this way, not only the aesthetic appearance of the fan module 300 is maintained, but also the space of the chassis 100 is not occupied.

[0102] Figure 6 For Figure 3 the exploded view of the pull rod portion 400. Figure 7 is a schematic diagram of the pull rod portion 400 of the present embodiment being rotated into the recessed portion 326. As Figure 6 and Figure 7 shown, the pull rod portion 400 includes a carrier 410, a first hook portion 420, a second hook portion 430, and an elastic element 440. The carrier 410 carries the first hook portion 420, the second hook portion 430, and the elastic element 440. The first hook portion 420 is rotatably disposed on the frame 320 through a pivot 450 for removably engaging with the first buckle opening 114. Therefore, the pull rod portion 400 can rotate along the axis of the pivot 450 (such as the Y-axis) closer to or away from the second buckle opening 370 (or the recessed portion 326). The second hook portion 430 is slidably disposed on the carrier 410 for removably engaging with the second buckle opening 370. Therefore, the second hook portion 430 can slide along the first direction (such as the X-axis). The elastic element 440 is directly connected to the first hook portion 420 and the second hook portion 430 respectively.

[0103] More specifically, the carrier 410 includes a sheet body 411 and a U-shaped cover 412. The U-shaped cover 412 covers the sheet body 411, and the U-shaped cover 412 and the sheet body 411 together define a receiving duct 413. The first hook portion 420, the elastic element 440, and the second hook portion 430 are all received within the receiving duct 413, and the first hook portion 420, the elastic element 440, and the second hook portion 430 are arranged in sequence along the first direction (such as the X-axis). One long side of the sheet body 411 further has a stop flange 414 facing the second hook 434. However, the present invention is not limited thereto.

[0104] The first hook portion 420 includes a first connecting portion 421 and a first hook 422. The first connecting portion 421 and the first hook 422 are disposed opposite to each other. The first hook 422 extends in the first direction (such as the X-axis), and the first hook 422 is used for removably engaging with the first buckle opening 114. The first hook portion 420 is further fixed to the sheet body 411 and the U-shaped cover 412 by a fixing bolt 460.

[0105] The second hook portion 430 includes a pushing portion 431, a guiding long hole 432, a second connecting portion 433, a second hook 434 and a pin 435. The pushing portion 431 and the second connecting portion 433 are disposed opposite to each other, and the second hook 434 extends in a vertical direction (such as the Z axis). The second hook 434 is used for removably engaging with the second buckle opening 370. The guiding long hole 432 is located between the pushing portion 431 and the second connecting portion 433, and the guiding long hole 432 extends along a first direction (such as the X axis). The pin 435 is inserted into the sheet body 411 and the U-shaped cover 412 at the same time and passes through the guiding long hole 432, so that the first hook portion 420 can perform linear sliding relative to the pin 435 within the accommodating duct 413. The elastic element 440 is, for example, a compression spring. Two ends of the elastic element 440 are respectively connected to the first connecting portion 421 and the second connecting portion 433. However, the present invention is not limited to the type of the elastic element 440.

[0106] As Figure 2 and Figure 7 shown, after the user loads one of the fan modules 300 into the box body 110 in the direction V1, the second connector 500 of the fan module 300 is inserted into the first connector 220, and the fan module 300 is limited on the circuit board 200 and the rear side plate 112A of the box body 110 ( Figure 4 ).

[0107] Then, the user completely turns the pull rod portion 400 into the recessed portion 326 through the first hook portion 420 in the direction C1, so that the first hook portion 420 is engaged with the first buckle opening 114, thereby preventing the fan module 300 from moving upward in the vertical direction (such as the Z axis), and the second hook portion 430 is engaged with the second buckle opening 370, thereby preventing the pull rod portion 400 from turning away from the second buckle opening 370 or the recessed portion 326. Therefore, the fan module 300 can be stably located within the box body 110 and cannot be separated from the box body 110. At this time, since the stop flange 414 directly abuts against the inner wall 328 of the recessed portion 326, the inner wall 328 of the recessed portion 326 can stop the pull rod portion 400 from continuing to rotate in the direction C1, thereby protecting the pull rod portion 400 and the carrying frame 310.

[0108] Figures 8A to 8C is a continuous operation diagram of the fan module 300 of this embodiment detaching from the chassis. On the contrary, when the user wants to remove one of the fan modules 300 from the box body 110, as Figure 8A and Figure 8B shown, first, the user presses the second hook portion 430 in the direction D1 through the pushing portion 431, not only making the second hook 434 no longer engage with the second buckle opening 370, but also making the second hook portion 430 and the first hook portion 420 jointly compress the elastic element 440.

[0109] Then, if Figure 8B and Figure 8C As shown, the user begins to rotate the pull rod portion 400 through the first hook portion 420 in the direction C2 to move out of the recessed portion 326, so that the first hook 422 of the first hook portion 420 rotates out of the first buckle opening 114, and the second hook 434 of the second hook portion 430 rotates out of the second buckle opening 370. At this time, the elastic element 440 pushes the second hook portion 430 back to its original position in the direction D2.

[0110] Then, if Figure 8C As shown, the user can use the pull rod 400 as a force-applying handle to lift the fan module 300 in the direction V2, thereby separating the second connector 500 of the fan module 300 from the first connector 220 and pulling the housing 110 upward from the chassis ( Figure 8C ).

[0111] Thus, through the above structure, the electronic device and the fan module thereof of the present invention can allow operators to quickly and easily install and remove the fan module from the chassis, thereby reducing production time and production costs.

[0112] Finally, the above disclosed embodiments are not intended to limit the present invention.
