[0052] The detailed description and technical content of this application are described below in conjunction with the drawings. However, the attached drawings are only for reference and illustration, and are not intended to limit this application.

[0053] This application provides a quickly disassemblable and assemblable cooling fan. As Figure 5 and Figure 6 shown, the quickly disassemblable and assemblable cooling fan (hereinafter referred to as the cooling fan) includes a fan body 100 and a fan carrier 500. This application can quickly assemble the fan body 100 on the fan carrier 500, or quickly disassemble the fan body 100 from the fan carrier 500.

[0054] As Figures 1 to 6 shown, the fan body 100 includes: a fan module 1, a bearing structure 2, and a main circuit board 3.

[0055] The bearing structure 2 has a bearing seat 23 and at least one beam integrally extending from the bearing seat 23. Specifically, a first beam 21 and a second beam 22 integrally extend from one location and another location of the bearing seat 23 respectively. The first beam 21 and the second beam 22 can extend back to back with each other and be collinear, but this is not limited thereto. The bearing seat 23 protrudes with a shaft sleeve 232, and at least one bearing (omitted in the figure) is arranged inside the shaft sleeve 232. The first beam 21 has a snap end 211 for snap connection. Preferably, the snap end 211 may further have a snap body 2111. The shape of the snap body 2111 is not limited in this application as long as it can be used for snap connection. In addition, the snap body 2111 can protrude upward, laterally, or both upward and laterally from the snap end 211.

[0056] The main circuit board 3 is arranged on the bearing seat 23. Specifically, its bottom surface is flatly attached and overlapped on the top surface of the bearing seat 23. The shape of the bearing seat 23 is not limited in this application. In this embodiment, it is illustrated by taking the shape corresponding to the main circuit board 3 as an example. A conductive connector 31 is also electrically configured on the bottom surface of the main circuit board 3. The conductive connector 31 can be any connector that can be used for electrical conduction. In this embodiment, it is illustrated by taking a spring pin connector as an example.

[0057] The fan module 1 is rotatably connected to the bearing seat 23, enabling the fan module 1 to rotate relative to the bearing structure 2. The fan module 1 is the same as the existing fan module and includes components such as an impeller, a rotor, and a core shaft (omitted in the figure). Therefore, the fan module 1 is rotatably connected to the shaft sleeve 232 by its core shaft, and a stator (omitted in the figure) is arranged on the shaft sleeve 232.

[0058] Still as Figures 1 to 6 shown, the fan carrier 500 includes a fan frame 5, a bridge 6, and a sub-circuit board 7.

[0059] A shroud 52 that is connected to each other and surrounded is connected inside the fan frame 5. The shroud 52 has a bottom edge 521, and a space 51 inside the frame is enclosed by the shroud 52 for accommodating the aforementioned impeller. The shroud 52 has a snap portion 522. The snap portion 522 can be various structures for being snap-connected. In this embodiment, it is illustrated by taking a notch formed from the bottom edge 521 as an example.

[0060] The bridge 6 extends from one location on the inner wall surface of the shroud 52 towards the direction where the snap portion 522 is located and forms an extension end (element symbol not marked). The extension end and the snap portion 522 are spaced apart and opposite to each other. The bridge 6 can be of various shapes. In this embodiment, it is illustrated by taking the shape corresponding to the bearing structure 2 and having a length longer than that of the bearing structure 2 as an example.

[0061] The secondary circuit board 7 is fixed to the bottom surface of the bridge 6, and the secondary circuit board 7 has a connection part (not marked with an element symbol) corresponding to the connection connector 31. The connection part may include a plurality of gold fingers, but is not limited thereto. The secondary circuit board 7 is connected with a transmission line group 72, and the transmission line group 72 extends along the bottom surface of the bridge 6 as Figure 3 shown. In addition, one end of the transmission line group 72 is electrically connected to the aforementioned connection part of the secondary circuit board 7.

[0062] As Figures 5 to 7 shown, when assembling, first buckle the buckle end 211 of the carrier structure 2 to the buckle part 522 of the fan frame 5 with its buckle body 2111 (specifically, the buckle body 2111 is buckled to the outer wall surface of the surrounding plate 52 through the buckle part 522), and then swing the other end of the carrier structure 2 downward with the buckle end 211 as the axis, so that the carrier structure 2 can be stacked on the top surface of the bridge 6 with its bottom surface, and at the same time, the connection connector 31 can be electrically contacted with the aforementioned connection part on the secondary circuit board 7; in this way, not only can the fan body 100 be quickly assembled to the fan carrier 500, but also the fan body 100 can be electrically connected to the transmission line group 72 while the assembly is completed.

[0063] Therefore, the cooling fan of the present application can quickly assemble the fan body 100 to the fan carrier 500 and electrically connect the fan body 100 to the transmission line group 72 while the assembly is completed; conversely, the cooling fan of the present application can also quickly disassemble the fan body 100 from the fan carrier 500 and make the fan body 100 no longer electrically connected to the transmission line group 72 while the disassembly is completed. That is: it can electrically connect the transmission line group 72 while the quick assembly is completed, and should no longer be electrically connected to the transmission line group 72 while the quick disassembly is completed.

[0064] In order to improve the connection strength between the fan body 100 and the fan carrier 500, a first fixing member 221 may be provided on the second beam 22, and a first corresponding fixing member 61 may be provided at the corresponding position of the bridge 6. As long as the first fixing member 221 is fixed to the first corresponding fixing member 61, the fan body 100 can be detachably fixed to the fan carrier 500. Specifically, the first fixing member 221 may be a screwed component and penetrate through a through hole 222 opened in the second beam 22, and the first corresponding fixing member 61 may be a screw hole.

[0065] As Figure 1 、 Figure 3 and Figure 6 shown, the secondary circuit board 7 can be fixed to the bridge 6 in any way. In this embodiment, the secondary circuit board 7 is fixed to the bridge 6 with a second fixing member 73. Specifically, a through hole 71 is opened in the secondary circuit board 7, a second corresponding fixing member 63 is provided on the bridge 6, and the second fixing member 73 is fixed to the second corresponding fixing member 63 through the through hole 71 of the secondary circuit board 7.

[0066] To facilitate the electrical contact between the guiding connector 31 and the secondary circuit board 7, a first through hole 231 can be formed in the bearing seat 23, and a second through hole 62 can be formed in the bridge 6. The first through hole 231 and the second through hole 62 correspond to each other. In this way, when assembling the fan body 100, when the other end of the bearing structure 2 swings downward and the entire bearing structure 2 is stacked on the top surface of the bridge 6, the guiding connector 31 can be electrically connected to the secondary circuit board 7 by passing through the first through hole 231 and the second through hole 62.

[0067] As Figure 1 and Figure 8 shown, in order to have a limiting function during the rapid assembly of the fan body 100, at least one limiting member can be provided on the bridge 6, and at least one corresponding limiting member can be provided on the bearing structure 2. Specifically, a first corresponding limiting member 213 and a second corresponding limiting member 223 are respectively provided on the first beam 21 and the second beam 22, and the bridge 6 is correspondingly provided with a first limiting member 64 and a second limiting member 65, so that the first limiting member 64 and the first corresponding limiting member 213 limit each other, and the second limiting member 65 and the second corresponding limiting member 223 limit each other.

[0068] Among them, the first limiting member 64 and the second limiting member 65 can be bumps protruding from the top surface of the bridge 6, and the first corresponding limiting member 213 and the second corresponding limiting member 223 can be a notch and a recess groove respectively, and an opening 2231 (as shown in Figure 1 ) is formed at the aforementioned other end of the bearing structure 2 corresponding to the recess groove.

[0069] In addition, in order to reinforce the shroud 52, as Figure 4 shown, at least one reinforcing rib 523 can be integrally protruded from the outer wall surface of the shroud 52 provided with the buckle portion 522, and the buckle body 2111 is buckled on the reinforcing rib 523.

[0070] In summary, the quick-disassembly and quick-assembly type cooling fan of the present application can indeed achieve the expected usage purposes and effects, and can solve the deficiencies of the prior art. Therefore, a patent application is filed.

[0071] The above is only the preferred feasible embodiment of the present application, and it does not limit the patent scope of the present application. Any equivalent structural changes made by using the content of the specification and drawings of the present application shall be included in the scope of the rights of the present application, and this is hereby stated.
