[0002] Fans are applied in many occasions that require heat dissipation, especially in electronic devices with concentrated heat generation. Traditional fans are of a single-piece type, and their volume and size are usually determined at the time of factory production. When encountering some scenarios with a large heat dissipation requirement, it is often necessary to increase the number of fans according to specific needs. However, such traditional single-piece fans require independent power supply, which means that there will be numerous wires when multiple fans are used simultaneously. In actual use, problems such as messy wiring, difficult wire management, and insufficient interfaces will occur.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] The present utility model discloses a fan and its fan module that are convenient for assembly and disassembly. Among them, the fan module includes two or more fans assembled in sequence and an external power connector.

[0026] The fan includes a fan body. The fan body is provided with a first connection component and / or a second connection component. The first connection component includes one or more first conductive structures, and the second connection component includes one or more second conductive structures. The first conductive structure is a conductive pin, and the second conductive structure is a contact foil. When two adjacent fan bodies are assembled, the first connection component of one fan body is mechanically and electrically connected to the second connection component of the other fan body, so that the two adjacent fans are mechanically and electrically connected.

[0027] As Figure 1 shown, the fan module 1 includes three or more fans 2. The three or more fans 2 are assembled in sequence. Between two adjacent fans 2, the first connection component of one fan 2 is mechanically and electrically connected to the second connection component 200 of the other fan 2, so as to realize mechanical and electrical connection between two adjacent fans 2.

[0028] It should be noted that when there are more than three fans 2 included in the fan module 1, for the fans other than the two outermost fans 2 in the fan module 1, one first connection component and one second connection component 200, or two first connection components, or two second connection components 200 must be provided.

[0029] As Figure 1 shown, the fan module 1 includes more than three fans 2 that are convenient for assembly and disassembly; the more than three fans 2 are assembled in sequence;

[0030] The fan module 1 further includes an external power connector 3; the external power connector 3 includes a first connection component or a second connection component;

[0031] The first connection component of the external power connector 3 is mechanically and electrically connected to the second connection component of one of the outermost fans in the fan module 1, so that the external power connector 3 is mechanically and electrically connected to the outermost fan; or,

[0032] The second connection component of the external power connector 3 is mechanically and electrically connected to the first connection component of one of the outermost fans in the fan module 1, so that the external power connector 3 is mechanically and electrically connected to the outermost fan.

[0033] Next, taking a fan module including two fans as an example, the structure of the fan and the assembly method of two adjacent fans will be described in detail:

[0034] As Figure 2 and Figure 3 shown, in this embodiment, the fan module 1 includes two mutually spliced fans. For the sake of clear description, the two fans are respectively named the first fan 21 and the second fan 22. The first fan 21 includes a first fan main body 201, and the second fan 22 includes a second fan main body 202.

[0035] As Figure 2 and Figure 3 shown, on the side of the first fan main body 201 close to the second fan main body 202, a first connection component 100 is provided. On the side of the second fan main body 202 close to the first fan main body 201, a second connection component 200 is provided.

[0036] As Figure 4 and Figure 5 shown, the first connection component 100 includes a plurality of first conductive structures. Of course, in other embodiments, the number of the first conductive structures can also be one or two. In this embodiment, the first conductive structure is a conductive pin 110.

[0037] As Figure 5 and Figure 6As shown, the first connection component 100 further includes a bump base 120 and a first PCB board 130. A clamping end 121 is provided on the bump base 120. The conductive pins 110 are provided on the bump base 120 and are electrically connected to the first PCB board 130.

[0038] As shown in Figure 4 and Figure 7 shown, the second connection component 200 includes a plurality of second conductive structures. Of course, in other embodiments, the number of the second conductive structures may also be one or two. In this embodiment, the second conductive structure is a contact foil 210.

[0039] As Figure 7 and Figure 8 shown, the second connection component 200 further includes a groove 220 and a second PCB board 230. The groove 220 is used to accommodate the bump base 120. And a limiting channel 221 that cooperates with the clamping end 121 is formed on the side wall of the groove 220. The contact foil 210 is disposed on the second PCB board 230. The contact foil 210 is used to cooperate with the conductive pins 110. When the contact foil 210 contacts the conductive pins 110, the first fan body 201 is electrically connected to the second fan body 202.

[0040] When the first fan 21 and the second fan 22 are assembled, the first connection component 100 and the second connection component 200 are buckled with each other. The clamping end 121 of the bump base 120 falls into the limiting channel 221, and the conductive pins 110 are pressed on the contact foil 210. In this way, the cooperation between the clamping end 121 and the limiting channel 221 enables the bump base 120 to be stably clamped in the groove 220, thereby realizing the stable connection of the two fans; the contact and cooperation between the conductive pins 110 and the contact foil 210 realizes the electrical connection of the two fans, thus solving the power supply problem during the assembly of the two fans. That is to say, an external power supply can supply power to one fan through the other fan.

[0041] In this embodiment, as Figure 7 and Figure 8 shown, the limiting channel 221 includes a longitudinal opening section 222 and a transverse closing section 223. When the first fan body 201 and the second fan body 202 are assembled side by side, the clamping end 121 of the bump base 120 enters the limiting channel 221 from the longitudinal opening section 222 and is locked in the transverse closing section 223. The specific clamping process will be described below.

[0042] As Figure 5 and Figure 7As shown, in this embodiment, the number of conductive pins 110 is multiple, and the multiple conductive pins 110 are arranged side by side. The number of contact foils 210 is multiple, and the multiple contact foils 210 are distributed in a fan shape outward with the center of the groove 220 as the center. As a preferred embodiment, the number of fan-shaped contact foils 210 is two, and the two fan-shaped contact foils 210 are symmetrically distributed. When the first fan 21 and the second fan 22 are assembled, the multiple conductive pins 110 are respectively in contact with the multiple contact foils 210 one by one; and since the contact foils 220 are distributed in a fan shape, this increases the range that the conductive pins 110 can contact, improving the stability of the electrical connection between the first fan 21 and the second fan 22.

[0043] It should be noted that the external power connector 3 includes a first connection component or a second connection component. As Figure 9 shown, in this embodiment, the external power connector 3 includes a second connection component 200, and the second fan 22 further includes a first connection component (not shown in the figure). The second connection component 200 of the external power connector 3 is mechanically and electrically connected to the first connection component of the second fan 22. Of course, in other embodiments, the external power connector 3 can also be set to be mechanically and electrically connected to the first fan 21. At this time, the first fan 21 needs to be provided with a corresponding first connection component to be mechanically and electrically connected to the second connection component 200 of the external power connector 3. As Figure 9 shown, the external power connector 3 further includes an external power cord 310, and the external power cord 310 is electrically connected to the second PCB board of the second connection component 200.

[0044] As Figure 3 and Figure 9 shown, when in use, the external power connector 3 is connected to an external power supply through the external power cord 310, thereby supplying power to the fan module 1.

[0045] In other embodiments, the external power connector 3 can be set to include a first connection component. The first connection component of the external power connector 3 is mechanically and electrically connected to the second connection component of the adjacent fan.

[0046] As Figure 10 shown, the first fan body 201 further includes: a fan frame 11, fan blades 12, and a motor. The motor is connected to the first PCB board and / or the second PCB board through a power supply line. The fan frame is provided with a wire storage groove 13 for fixing the power supply line. It should be noted that the second fan body also further includes: a fan frame, fan blades, and a motor. The motor is connected to the first PCB board and / or the second PCB board through a power supply line. The fan frame is provided with a wire storage groove for fixing the power supply line.

[0047] Next, in combination with the above structure, the working principle of the fan module 1 in this embodiment will be elaborated:

[0048] When assembling the fan module 1, align the first connection component 100 of the first fan body 21 with the second connection component 200 of the second fan 22, that is, the bump base 120 is opposite to the groove 220. At this time, the second fan 22 is inclined relative to the first fan 21, which is to align the clamping end 121 with the longitudinal opening section 222. Subsequently, bring the second fan 22 close to the first fan 21, and the bump base 120 enters the groove 220. In this way, the clamping end 121 enters the longitudinal opening section 222, and the conductive pin 110 presses on the contact foil 210. Immediately afterwards, rotate the second fan 22 (of course, the first fan 21 can also be rotated at this time) so that the second fan 22 is parallel to the first fan 21, then the clamping end 121 enters the transverse closed section 223 from the longitudinal opening section 222. In this way, the clamping end 121 is locked in the limit channel 221, and the bump base 120 is received in the groove 220, thus realizing a stable mechanical connection between the two fans; at the same time, after assembly, the conductive pin 110 always presses on the contact foil 210, realizing a stable electrical connection between the two fans.

[0049] Similarly, the user can connect the external power connector 3 to the first connection component (not shown in the figure) of the second fan 22 by using the same rotary snap connection method. In this way, the external power will be sequentially transmitted to the second fan 22 and the first fan 21 through the external power connector 3.

[0050] When disassembling, the user only needs to rotate the second fan 22 in the opposite direction (of course, the first fan 21 can also be rotated at this time), so that the clamping end 121 moves from the transverse closed section 223 to the longitudinal opening section 222, and then withdraw the clamping end 121 from the longitudinal opening section 222, then the separation of the two fans can be completed. After separation, the conductive pin 110 no longer contacts the contact foil 210, and the circuit between the two fans is disconnected.

[0051] Compared with the prior art, the fan module 1 and the fan 2 of the present utility model have the following features and

[0052] Beneficial effects:

[0053] First, the first connection component 100 and the second connection component 200 are connected by a rotary snap connection method. After assembly, the clamping end 121 can bear the external force in the axial direction, and the bump base 120 can bear the external force in the radial direction, so as to solve the problem of unreliable connection in the prior art;

[0054] Second, the electrical connection method of using the conductive pin 110 to contact the contact foil 210 is adopted, avoiding the need to separately set a separate connection seat (or connecting wire), and thus the problem that the connection seat (or connecting wire) is easily lost accidentally in the prior art will not occur;

[0055] Thirdly, the contact foil 210 is in a fan-shaped structure, which expands the contact range of the conductive pins 110. That is, when the first connection component 100 is attached to the second connection component 200, the circuit can be connected, thus improving the stability of the contact connection. At the same time, the large-area contact foil 210 is also beneficial to heat dissipation.

[0056] Furthermore, in order to achieve a more stable and good contact between the conductive pins 110 and the contact foil 210, in this embodiment, the conductive pins 110 adopt a POGO pin structure (also known as a spring ejector pin). Specifically, the conductive pin 110 includes a pin shaft, a pin tube, and a spring (not shown in the figure) disposed between the pin shaft and the pin tube. The pin tube is connected to the first PCB board 130. When the fan module is in the assembled state, the spring will be compressed, and the pin shaft contacts and presses on the contact foil 210 of the second PCB board 230. Due to the presence of the spring, the pin shaft will always tightly press on the contact foil 210 to ensure a good contact effect (the POGO pin structure is a prior art well-known to those skilled in the art, so the present invention will not be described in detail).

[0057] Preferably, the contact foil 210 is a copper sheet, and the surface of the pin shaft of the conductive pin 110 is plated with a gold layer. The contact foil 210 can provide good electrical conductivity and heat dissipation performance, while plating the pin shaft of the conductive pin 110 with gold can better improve its anti-corrosion function, mechanical properties, and electrical properties.

[0058] In summary, the fan and its fan module of the present invention that are convenient for assembly and disassembly can not only achieve stable mechanical connection and electrical connection between multiple fans, but also reduce the number of accessories, bringing convenience to users.

[0059] The above-described embodiments merely represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
