[0074] The following will disclose multiple embodiments of the utility model with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. However, those skilled in the art should understand that in some embodiments of the utility model, these practical details are not necessary and should not be used to limit the utility model. In addition, in order to simplify the drawings, some commonly used structures and components will be illustrated in a simple schematic manner in the drawings. In addition, for the convenience of readers, the sizes of the components in the drawings are not drawn according to the actual scale.

[0075] Figure 1FIG. 1 is a three-dimensional diagram of a fan module 10 according to an embodiment of the present invention. Figure 2 for Figure 1 The exploded view of the fan module 10 is shown in FIG. Figure 1 and Figure 2 As shown, in this embodiment, the fan module 10 includes a fan fixing frame 100 and a first fan unit 700. The fan fixing frame 100 includes a frame 110, a first holding portion 200 and a second holding portion 300. The frame 110 has a receiving groove 150. The first holding portion 200 and the second holding portion 300 are respectively located on the frame 110. The first fan unit 700 is removably received in the receiving groove 150 and is held by the first holding portion 200 and the second holding portion 300.

[0076] In the present embodiment, more specifically, the first fan unit 700 includes a housing 710, two end plates 720, a wire 730, a connector 740 and a fan body (not shown in the figure). The housing 710 is between these end plates 720 and is integrally connected to these end plates 720. Each end plate 720 is rectangular, and each corner portion 721 of the end plate 720 has a positioning hole 722. The fan body (not shown in the figure) is rotatably disposed in the housing 710, and is externally connected to a connector 740 through the wire 730 for outputting airflow to the outside. In the present embodiment, the first fan unit 700 is, for example, a dual-rotor fan, and the space size of the first fan unit 700 and the accommodating groove 150 is roughly matched.

[0077] In this embodiment, the frame 110 includes a bottom plate 120, a side plate 130 and two protective covers 140. The protective covers 140 are arranged opposite to each other, the bottom plate 120 is located between the protective covers 140, and the side plate 130 is located between the protective covers 140. The bottom plate 120 is adjacent to the side plate 130 and the protective covers 140 respectively, and the side plate 130 is adjacent to the protective covers 140 respectively, so that the bottom plate 120, the side plate 130 and the protective covers 140 jointly define the above-mentioned receiving groove 150. More specifically, in Figure 2 In the embodiment, the bottom plate 120 extends along the XY direction, the side plate 130 extends along the XZ direction, and each protective cover 140 extends along the YZ direction.

[0078] Figure 3 for Figure 2 An exploded view of the fan fixing bracket 100 is shown. Figure 2 and Figure 3 As shown, in this embodiment, the fan fixing bracket 100 further includes a bracket 500. The bracket 500 is fixedly connected to the frame 110, is located outside the receiving groove 150, and removably carries the connector 740 ( Figure 1 ).

[0079] More specifically, the frame 110 further includes an outer flange 160 and a plurality of positioning pins 162. The outer flange 160 is connected to the bracket 500. The positioning pins 162 extend from the top surface 161 of the outer flange 160, and are arranged in a triangular profile, for example, to pass through the bracket 500 and position the bracket 500. Furthermore, the outer flange 160 extends from a side of the bottom plate 120 opposite to the side plate 130, and is integrally connected to the bottom plate 120.

[0080] In addition, the first retaining portion 200 includes two first extension ribs 210 opposite to each other. The first extension ribs 210 are respectively located on the inner wall 111 and the outer flange 160 of the frame 110. For example, one of the first extension ribs 210 extends horizontally from a side of the side plate 130 facing the receiving groove 150 (such as the inner wall 111) along the Y axis, and the other first extension rib 210 extends vertically (such as the Z axis) from the top surface 161 of the outer flange 160. Each first extension rib 210 has a first protrusion 220, and the first protrusion 220 extends from one side of the first extension rib 210 along the X axis toward one of the protective covers 140.

[0081] The second retaining portion 300 includes two second extension ribs 310 opposite to each other. The second extension ribs 310 are respectively located on the inner wall 111 and the outer flange 160 of the frame 110. For example, one of the second extension ribs 310 extends horizontally from a side of the side plate 130 facing the receiving groove 150 (such as the inner wall 111) along the Y axis, and the other second extension rib 310 extends vertically (such as the Z axis) from the top surface 161 of the outer flange 160. Each second extension rib 310 has a second protrusion 320, and the second protrusion 320 extends from one side of the second extension rib 310 along the X axis toward the other protective cover 140.

[0082] So, like Figure 1 and Figure 2 As shown, when the first fan unit 700 is moved into the receiving groove 150, each first protrusion 220 extends into and abuts against the positioning hole 722 of the end plate 720 on the right side of the first fan unit 700, and each second protrusion 320 extends into and abuts against the positioning hole 722 of the end plate 720 on the left side of the first fan unit 700. In this way, the first fan unit 700 can be removably retained in the receiving groove 150, thereby completing the installation of the first fan unit 700. Conversely, when the first extension rib 210 and the second extension rib 310 are respectively pulled so that each first protrusion 220 and the second protrusion 320 are respectively disengaged from the corresponding positioning hole 722, the first fan unit 700 can be removed from the receiving groove 150 without tools.

[0083] Furthermore, the inner wall 111 of the frame 110 facing the accommodating groove 150 further has a buffer pad 600. For example, the buffer pad 600 is attached to one side of the side plate 130 facing the accommodating groove 150 to contact and protect the first fan unit 700 in the accommodating groove 150. For example, the buffer pad 600 is a soft material such as buffer rubber.

[0084] like Figure 2 and Figure 3 As shown, the fan fixing frame 100 further includes an indicator light bracket 170, which is disposed on the side plate 130 of the frame 110, so that the indicator light 750 of the first fan unit 700 can be installed therein, thereby sending a corresponding signal to the outside. However, the utility model is not limited thereto, and the indicator light 750 may also be omitted in other embodiments.

[0085] Figure 4A and Figure 4B They are Figure 2 FIG. 5 is a schematic diagram of the operation of installing the connector 740 and the bracket 500. Figure 3 and Figure 4A As shown, the connector 740 includes a plate body 741 and a plug-in portion 743, and the plug-in portion 743 extends from a side 742 of the plate body 741 for electrically connecting an external device (not shown). The bracket 500 includes a base 510, two first positioning ribs 520 and two second positioning ribs 540. The base 510 has a plurality of through holes 511, and these through holes 511 can be respectively passed through by these positioning pins 162. These first positioning ribs 520 are arranged on the base 510 at intervals, and an opening 522 is formed between these first positioning ribs 520. These second positioning ribs 540 are arranged on the base 510 at intervals, and a accommodating gap 550 is formed between the first positioning ribs 520. One end of each first positioning rib 520 has a positioning hook 530. These positioning hooks 530 of these first positioning ribs 520 all extend toward the Y axis together.

[0086] So, like Figure 4A and Figure 4B As shown, when the plate body 741 of the connector 740 is inserted into the accommodating gap 550 along the Z axis so that the plug-in portion 743 is just moved into the opening 522 between these first positioning ribs 520, until these positioning hooks 530 are respectively hooked to the long side edges 741L of the plate body 741, the connector 740 can be positioned on the bracket 500 without tools.

[0087] Figure 5A FIG. 1 is a three-dimensional diagram of a fan module 10 according to an embodiment of the present invention. Figure 5B for Figure 5A A perspective view of the second fan unit 800. Figure 2 and Figure 5AAs shown, in this embodiment, the fan fixing bracket 100 further includes a third fixing portion 400 . The third fixing portion 400 is located on the frame 110 and between the first fixing portion 200 and the second fixing portion 300 .

[0088] Thus, when the fan fixing frame 100 is replaced by placing the second fan unit 800 therein, and the size of the second fan unit 800 is smaller than Figure 2 When the size of the first fan unit 700 is shown (i.e., a gap G is formed between the second fan unit 800 and the other protective cover 140), the second fan unit 800 can be fixed in the receiving groove 150 by the first fixing portion 200 and the third fixing portion 400. In this embodiment, the second fan unit 800 is, for example, a single-rotor fan, and the second fan unit 800 is smaller than the space size of the receiving groove 150.

[0089] More specifically, the third retaining portion 400 includes two third extension ribs 410 opposite to each other. These third extension ribs 410 are respectively located on the inner wall 111 and the outer flange 160 of the frame 110. For example, one of the third extension ribs 410 extends from a side of the side plate 130 facing the receiving groove 150, and the other third extension rib 410 extends vertically from the top surface 161 of the outer flange 160, and each third extension rib 410 has a third protrusion 420. These third protrusions 420 of these third extension ribs 410 extend toward the other protective cover 140 together.

[0090] Thus, when the second fan unit 800 is moved into the receiving groove 150, each first protrusion 220 extends into and abuts against the positioning hole 722 of the end plate 720 on the right side of the first fan unit 700, and each third protrusion 420 extends into and abuts against the positioning hole 722 of the end plate 720 on the left side of the first fan unit 700, so that the second fan unit 800 can be removably retained in the receiving groove 150, thereby completing the installation of the second fan unit 800. Conversely, when the first extension rib 210 and the third extension rib 410 are pulled, the second fan unit 800 can be removed from the receiving groove 150 without tools.

[0091] Fig. 6A and Figure 6B FIG. 7 is a schematic diagram of a continuous assembly of a connector 740A and a bracket 500 of a fan unit according to an embodiment of the present invention. Fig. 6A and Figure 6B As shown, the bracket 500 of this embodiment is substantially the same as the bracket 500A of the above embodiment, except that the first positioning ribs 520 of the bracket 500 do not have the positioning hooks 530 ( Figure 4A), but the first positioning ribs 520 are stopper ribs 521 extending laterally in opposite directions (such as the X axis) from each other. The connector 740A further includes a plurality of positioning protrusions 744, which are symmetrically protruded from the surface 742 of the plate body 741.

[0092] So, like Fig. 6A and Figure 6B As shown, when the plate body 741 of the connector 740A is inserted into the accommodating gap 550 along the Z axis, the stop ribs 521 stop the positioning protrusions 744 respectively, and the connector 740A can be positioned on the bracket 500 without tools.

[0093] Thus, through the above structure, the fan fixing bracket and the fan module of the utility model can be flexibly configured with fan units of different sizes according to requirements or restrictions, thereby reducing material costs and material storage costs.

[0094] Finally, the above disclosed embodiments are not intended to limit the present invention. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all of them can be protected by the present invention. Therefore, the scope of protection of the present invention shall be determined by the definition of the attached claims.
