The terminology used in the specification of the present application herein is only for the purpose of describing the specific embodiments and is not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The present application provides a fan set 10 for ease of assembly, such as Figure 1 and Figure 2As shown, it comprises: at least two fan bodies 100, each of which comprises an outer frame 110 provided with a connecting structure 120; a coupling piece 200 for connecting adjacent two fan bodies 100. Figure 3 As shown, the coupling piece 200 is provided with two groups of contact structures 210 which are adapted to and detachably connected with the connecting structures 120.

[0030] When splicing, only one coupling piece 200 is needed to assemble adjacent two fan bodies 100 together, and the two groups of contact structures 210 of the coupling piece 200 are matched with the connecting structures 120 of the first and second fan bodies 100 respectively. It is worth noting that the connecting and matching of the coupling piece 200 not only realizes the physical connection of the two fan bodies 100, but also realizes the electrical connection, the specific principle of which will be described below.

[0031] As shown, Figure 5 The connecting structure 120 comprises conductive probes 121 and locking protrusions 122, the contact structure 210 comprises conductive contact pieces 211 matched with the conductive probes 121 and limiting grooves 212 matched with the locking protrusions 122, and the conductive contact pieces 211 of the two groups of contact structures 210 are electrically connected with each other.

[0032] In the embodiment, the two groups of conductive contact pieces 211 of the same coupling piece 200 are electrically connected through a flexible circuit board (commonly known as "soft board FPC") which is arranged inside the coupling piece 200 (not shown in the figure). Preferably, the coupling piece 200 is made of non-conductive material, such as hollow plastic material structure or rubber material.

[0033] In the embodiment, as shown in Figure 4 and Figure 5 The side wall of the locking protrusion 122 is provided with a notch groove 1221, and the corresponding position of the limiting groove 212 is provided with a anti-falling blocking edge 2121 corresponding to the notch groove 1221. When the locking protrusion 122 is matched with the limiting groove 212, the anti-falling blocking edge 2121 is clamped in the notch groove 1221. In this way, the connecting structure 120 and the contact structure 210 realize sliding clamping or disengagement, and when clamped, the anti-falling blocking edge 2121 and the notch groove 1221 cooperate to make the connection between the connecting structure 120 and the contact structure 210 more stable, thereby preventing the coupling piece 200 from being separated from the outer frame 110 at will.

[0034] Preferably, the conductive probe 121 is located at one side of the blocking protrusion 122 with the notch slot 1221, and the conductive contact patch 211 is located at one side of the anti-falling blocking edge 2121 of the limiting groove 212. Such arrangement helps to make the cooperation of the conductive probe 121 and the conductive contact patch 211 more closely when clamping, and structurally reduces the occurrence of the edge lifting phenomenon, and avoids the problem of poor contact caused by the edge lifting of the conductive probe 121 and the conductive contact patch 211 as much as possible.

[0035] In the embodiment, as shown in Figure 6 The fan body 100 includes a fan blade 130 and a motor (not shown), and the outer frame 110 is provided with a hollow barrel 111, one end face of the barrel 111 is provided with a fixing frame 112, the motor is fixedly installed on the fixing frame 112, the fan blade 130 is rotationally arranged in the barrel 111 of the outer frame 110, and the fan blade 130 is connected with an output shaft of the motor. Preferably, a PCB (not shown) is arranged in the outer frame 110, and the PCB is electrically connected with the motor and the conductive probe 121.

[0036] In combination with the above structure, the working principle of the fan group 10 convenient to assemble is described as follows:

[0037] When splicing, the plurality of fan bodies 100 are placed side by side; wherein Figure 2 and Figure 5 As shown in the reference The connecting structure 120 of the first fan body 100 and the connecting structure 120 of the second fan body 100 are close to each other. Then, the connecting piece 200 is abutted between the two fan bodies 100, and the connecting piece 200 is cooperated with the two connecting structures 120 in a sliding buckling manner. At this time, the two groups of contact structures 210 of the connecting piece 200 are cooperated with the connecting structure 120 of the first fan body 100 and the connecting structure 120 of the second fan body 100 respectively; the blocking protrusion 122 is sunk into the limiting groove 212, and the conductive probe 121 is in contact with the conductive contact patch 211. In this way, the outer frames 110 of the two fan bodies 100 are physically spliced through the connecting piece 200, and the conductive probes 121 of the two fan bodies 100 are also electrically connected through the connecting piece 200, so that the assembly between the fan bodies 100 is completed;

[0038] When disassembling, only the connecting piece 200 needs to be pushed in the reverse direction to make the contact structure 210 and the connecting structure 120 disengage, so as to release the clamping cooperation, and the electrical connection between the two fan bodies 100 is disconnected, and the two fan bodies 100 are independent again.

[0039] Compared with the prior art, the connecting piece 200 and the connecting structure 120 have the following beneficial effects: the wiring problem caused when the plurality of fan bodies 100 are assembled can be reduced by cooperation of the two, the functions of physical connection and electrical connection are simultaneously realized by the connecting piece 200, so that a plurality of wires do not need to be additionally arranged, the overall neatness is improved, and the traditional wire arrangement difficulty is solved, thereby realizing convenient and fast assembly and improving assembly efficiency.

[0040] In the embodiment, as shown in the figure, Figure 6 The inwardly recessed hiding groove 113 can have better waterproof effect, so that water droplets are avoided from entering the connecting structure 120 when sliding along the side wall of the outer frame 110, and then contacting the conductive probe 121 to cause a short circuit phenomenon.

[0041] In one of the embodiments, in order to make the conductive probe 121 and the conductive contact piece 211 have better conductive contact, the conductive probe 121 adopts a POGO spring needle structure (also called a spring thimble). Specifically, the conductive probe 121 comprises a needle shaft, a needle tube and a spring (not shown in the figure) arranged between the needle shaft and the needle tube. When the contact structure 210 cooperates with the connecting structure 120, the needle shaft contacts and holds on the conductive contact piece 211. Due to the presence of the spring, the needle shaft will always tightly hold on the conductive contact piece 211, thereby ensuring good contact effect (the POGO spring needle structure is a prior art known to those skilled in the art, so the utility model will not be described again).

[0042] Preferably, the conductive contact piece 211 is a copper material structure, and a gold layer is plated on the surface of the conductive contact piece 211 and the needle shaft. The conductive contact piece 211 of the copper material structure can provide good conductive performance and heat dissipation performance, and the gold plating on the surface of the needle shaft can better improve its corrosion resistance, oxidation resistance, mechanical properties and electrical properties.

[0043] In summary, the fan group 10 convenient to assemble can realize quick splicing of the plurality of fan bodies on the basis of realizing conduction, so that the overall wiring neatness is improved, and the subsequent assembly efficiency is also improved.

[0044] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a plurality of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
