[0050] See also Figures 1 to 3 . Figure 1 FIG. 4 is a schematic three-dimensional diagram of a fan module according to a first embodiment of the present invention. Figure 2 for Figure 1 Exploded view of the fan module. Figure 3 for Figure 1 A partial top view of a fan module is shown.

[0051] The fan module 10 of this embodiment includes a first fan device 20 and a second fan device 30. Since the structures of the first fan device 20 and the second fan device 30 are similar, the first fan device 20 is used for explanation below. The first fan device 20 includes a fan frame 21, a fan blade 22, a driving element 23, a main electrical connection port 24, a connecting line 25 and an electrical series connection member 26. The fan frame 21 has a side 211, a first assembly slot 212 and a second assembly slot 213. The fan blade 23 is rotatably disposed on the fan frame 21 and is located on one side of the side 211 of the fan frame 21. The driving element 23 each includes a stator (not shown) and a rotor (not shown). The stator and the rotor are, for example, matching magnets or coils. The stator is fixedly disposed on the fan frame 21. The rotor can rotate relative to the stator through electromagnetic effect to drive the fan blade 23 to rotate relative to the fan frame 21. The main electrical connection port 24 is disposed in the first assembly slot 212 and electrically connected to the driving element 23 .

[0052] The electrical serial connection member 26 is disposed in the second assembly slot 213 and includes a rotating member 261 and a serial electrical connection port 262. The rotating member 261 can rotate relative to the fan frame 21. The serial electrical connection port 262 is, for example, a circuit board with conductive contacts. The serial electrical connection port 262 is disposed on the rotating member 261 and is electrically connected to the main electrical connection port 24 through the connecting line 25, and the serial electrical connection port 262 of the first fan device 20 can be selectively electrically connected to the main electrical connection port 24 of the second fan device.

[0053] Please also read Figure 4 and Figure 5 . Figure 4 for Figure 1 A partial cross-sectional schematic diagram of a fan module. Figure 5 for Figure 1 A partially enlarged cross-sectional schematic diagram of a fan module.

[0054] In detail, the electrical serial connection member 26 includes a first fixing member 263. The first fixing member 263 is, for example, a magnet, and is disposed on the rotating member 261. The fan frame 21 includes a second fixing member 214. The second fixing member 214 is, for example, a magnet, and is disposed in the first assembly slot 212 of the fan frame 21. The first fixing member 263 can be selectively fixed to the second fixing member 214 by the rotation of the rotating member 261, so that the serial electrical connection port 262 of the first fan device 20 can be selectively electrically connected to the main electrical connection port 24 of the second fan device.

[0055] The first fan device 20 includes a terminal cable 27. One end of the terminal cable 27 is electrically connected to the main electrical connection port 24 of the first fan device 20, and the other end of the terminal cable 27 is electrically connected to an external power source (not shown). That is, the fan module 10 can receive power or control signals through the terminal cable 27.

[0056] In this embodiment, the first fan device 20 and the second fan device 30 have the advantage of being connected via the rotatable electrical serial connector 26, that the serial electrical connection port 262 of the first fan device 20 and the main electrical connection port 24 of the second fan device can be electrically connected by simply rotating the electrical serial connector 26, so that the first fan device 20 and the second fan device 30 are electrically connected in series, without the need to plug multiple cables into the first fan device 20 and the second fan device 30. In this way, the installation procedure of the fan module 10 can be simplified.

[0057] In addition, by fixing the first fixing member 263 provided on the electrical series connection member 26 and the second fixing member 214 provided on the second fan frame 21, the first fan device 20 and the second fan device 30 can be more firmly electrically connected in series without causing the circuit between the first fan device 20 and the second fan device 30 to be broken due to shaking or collision.

[0058] In this embodiment, the number of the fan devices 20 of the fan module 10 is two, but the present invention is not limited thereto. In other embodiments, the number of the fan devices of the fan module may also be more than three.

[0059] In this embodiment, the first fixing member 263 and the second fixing member 214 are magnets, but the present invention is not limited thereto. In other embodiments, one of the first fixing member and the second fixing member is a magnet, and the other can also be a metal sheet.

[0060] Please also read Figure 6 and Figure 7 . Figure 6 for Figure 1 A three-dimensional schematic diagram of a fan module in which a rotating member located in a first fan device has not yet rotated to a second fan device. Figure 7 for Figure 1 A three-dimensional schematic diagram of a fan module in which a rotating member located in a first fan device rotates to a second fan device.

[0061] like Figure 6 As shown, the electrical serial connection member 26 of the first fan device 20 is received in the second assembly slot 213, so the serial electrical connection port 262 of the first fan device 20 is not electrically connected to the main electrical connection port 24 of the second fan device 30. In other words, the first fan device 20 and the second fan device 30 are not yet electrically connected in series.

[0062] like Figure 7As shown, when the user wants to electrically connect the first fan device 20 and the second fan device 30 in series, first, the rotating member 261 of the electrical serial connection member 26 in the first fan device 20 can be rotated from the second assembly slot 213 along the direction A toward the second fan device 30, and the first fixing member 263 can be fixed to the second fixing member 214. When the first fixing member 263 is fixed to the second fixing member 214, the serial electrical connection port 262 of the electrical serial connection member 26 in the first fan device 20 can be electrically connected to the main electrical connection port 24 of the second fan device 30. Then, the user electrically connects the terminal cable 27 to the external power supply. In this way, power or control signals can be transmitted to the first fan device 20 and the second fan device 30 through the terminal cable 27 to drive the first fan device 20 and the second fan device 30 to operate at the same time.

[0063] On the contrary, when the user wants to release the electrical series connection between the first fan device 20 and the second fan device 30, the user can release the fixing of the first fixing member 263 and the second fixing member 214, and rotate the rotating member 261 of the electrical series connection member 26 in the first fan device 20 in the opposite direction of direction A away from the second fan device 30. In this way, the electrical connection between the series electrical connection port 262 of the electrical series connection member 26 in the first fan device 20 and the main electrical connection port 24 of the second fan device 30 can be released, and the electrical series connection between the first fan device 20 and the second fan device 30 can be released.

[0064] See also Figure 8 and Fig. 9 . Figure 8 FIG. 4 is a perspective schematic diagram of a fan device according to a second embodiment of the present invention. Fig. 9 for Figure 8 Exploded view of the fan assembly.

[0065] The fan device 20A of the present embodiment is similar to the fan device 20 of the fan module 10 of the first embodiment, so the differences between the present embodiment and the first embodiment will be described below, and the similarities will not be repeated. The fan device 20A of the present embodiment includes a fan frame 21A, a fan blade 22A, a driving element 23A, a main electrical connection port 24A, a connecting line 25A, an electrical series connector 26A and a terminal cable 27A. The fan frame 21A has a side 211A, a first assembly groove 212A and a second assembly groove 213A. The first assembly groove 212A and the second assembly groove 213A are located at opposite ends of the side 211A. The fan blade 22A is rotatably disposed on the fan frame 21A and is located on one side of the side 211A. The main electrical connection port 24A is disposed in the first assembly groove 212A and is electrically connected to the driving element 23A.

[0066] The electrical serial connection member 26A is disposed in the second assembly slot 213A and includes a rotating member 261A and a serial electrical connection port 262A. The rotating member 261A can rotate relative to the fan frame 21A. The serial electrical connection port 262A is disposed on the rotating member 261A and is electrically connected to the main electrical connection port 24A through the connecting line 25A. When only a single fan device 20A needs to be installed, the electrical serial connection member 26A can be stored in the second assembly slot 213A. In this way, the electrical serial connection member 26A will not protrude from the fan frame 21A and the installation space occupied by the fan device 20A can be reduced.

[0067] One end of the terminal cable 27A is electrically connected to the main electrical connection port 24A, and the other end of the terminal cable 27A is electrically connected to an external power source (not shown). In other words, the fan device 20A can receive power or control signals through the terminal cable 27A.

[0068] According to the fan device and fan module of the above embodiment, since the first fan device is provided with a rotatable electrical serial connector, the serial electrical connection port of the first fan device can be electrically connected to the main electrical connection port of the second fan device by simply rotating the electrical serial connector, so that the first fan device and the second fan device are electrically connected in series, without the need to plug multiple cables into the first fan device and the second fan device respectively. In this way, the installation procedure of the fan module can be simplified.

[0069] Although the present invention is disclosed as above with the aforementioned embodiments, it is not intended to limit the present invention.
