[0031] The utility model provides a modularization heat dissipation fan group 10, as shown in Figure 1 and Figure 2 It includes: at least two fan main bodies 100 and intermediate connecting piece 200, adjacent two fan main bodies 100 realize combination through intermediate connecting piece 200.

[0032] Among them, as shown in Figure 2 Each fan main body 100 includes outer frame 110, is equipped with splicing male part 120 on outer frame 110, and splicing male part 120 includes probe assembly 121 and ball striking assembly 122. Figure 3 and Figure 4 As shown in and

[0033] The cooperation of limiting block 212 and ball striking assembly 122 mainly plays the role of realizing physical connection. Figure 5 and Figure 6 Ball striking assembly 122 includes: first spherical bead 1221, second spherical bead 1222, upper cylindrical barrel 1223 and lower cylindrical barrel 1224, upper cylindrical barrel 1223 and lower cylindrical barrel 1224 are oppositely arranged on outer frame 110, first spherical bead 1221 is housed in upper cylindrical barrel 1223 through spring 1225, and second spherical bead 1222 is housed in lower cylindrical barrel 1224 through spring 1225.

[0034] Limiting block 212 of splicing female part 210 forms imitation bead groove 213 (as shown in Figure 4 ) that cooperates with first spherical bead 1221 and second spherical bead 1222. When splicing male part 120 cooperates with splicing female part 210, the limiting block 212 is trapped in the holding gap 1226, and the first spherical bead 1221 and the second spherical bead 1222 are both clamped in the imitation bead groove 213.

[0035] The conductive contact piece 211 is in contact with the probe assembly 121 to realize the conductive connection. Figure 6 As shown in the figure, the probe assembly 121 comprises a base 1211 and a plurality of probes 1212, the base 1211 is mounted on the outer frame 110, and the plurality of probes 1212 are fixedly arranged on the base 1211.

[0036] In the embodiment, the two conductive contact pieces 211 are electrically connected by a flexible circuit board (commonly known as FPC) in the same intermediate connecting piece 200, and the flexible circuit board is arranged inside the intermediate connecting piece 200. Preferably, the intermediate connecting piece 200 is made of non-conductive material, such as a hollow plastic material structure or a rubber material structure.

[0037] In the embodiment, as shown in the figure, Figure 7 The fan body 100 comprises a fan blade 130 and a motor (not shown in the figure), the outer frame 110 is provided with a hollow barrel 111, one end surface of the barrel 111 is provided with a fixing frame 112, the motor is fixedly mounted on the fixing frame 112, the fan blade 130 is rotatably arranged in the barrel 111 of the outer frame 110, and the fan blade 130 is connected with the output shaft of the motor. Preferably, the outer frame 110 is provided with a circuit board (not shown in the figure), and the circuit board is electrically connected with the motor and the probe assembly 121.

[0038] The working principle of the modularized cooling fan group 10 is described as follows:

[0039] When splicing, a plurality of fan bodies 100 are placed side by side; wherein, referring to Figure 2 and Figure 6 As shown in the figure, the splicing male part 120 of the first fan body 100 is close to the splicing male part 120 of the second fan body 100. Then, the intermediate connecting piece 200 is clamped between the two fan bodies 100. Specifically, the two splicing female parts 210 on the intermediate connecting piece 200 are matched with the splicing male part 120 of the first fan body 100 and the splicing male part 120 of the second fan body 100 respectively; the conductive contact piece 211 is in contact with the probe assembly 121, the limiting block 212 is pushed into the clamping notch 1226, and the first spherical bead 1221 and the second spherical bead 1222 are clamped in the imitation bead groove 213 (i.e. under the action of the elastic force of the spring 1225, the first spherical bead 1221 and the second spherical bead 1222 clamp the limiting block 212). In this way, the cooperation of the limiting block 212 and the impact bead assembly 122 realizes the physical connection of the two outer frames 110, the cooperation of the conductive contact piece 211 and the probe assembly 121 realizes the electrical connection of the two fan bodies 100, and thus the splicing and combination of the fan bodies 100 are completed;

[0040] When disassembling, only need to exert force to pull out the middle connecting piece 200 outward, the elastic force of the spring 1225 can be overcome, the first spherical bead 1221 and the second spherical bead 1222 are prompted to avoid, so that the limiting block 212 is separated from the clamping gap 1226. In this way, the middle connecting piece 200 is separated, and the adjacent two fan bodies 100 lose the connection basis, and are independent of each other again.

[0041] Compared with the prior art, the design of the splicing male part 120 and the splicing female part 210 has the following beneficial effects: the cooperation of the two can reduce the wiring problem generated when the plurality of fan bodies 100 are assembled, and the function of physical connection and electrical connection is realized at the same time through the middle connecting piece 200, so that a plurality of wires do not need to be additionally arranged, the overall neatness is improved, and the traditional wiring difficulty problem is solved, so that convenient and efficient assembly is realized, and the assembly efficiency is improved.

[0042] In the embodiment, as shown in Figure 5 The inwardly recessed hiding groove 113 can have better waterproof effect, so that when water droplets slide along the side wall of the outer frame 110, the water droplets cannot enter the splicing male part 120 and further contact the probe 1212, causing a short circuit phenomenon.

[0043] Further, in one of the embodiments, the probe 1212 adopts a POGO spring needle structure (also known as a spring thimble). Specifically, the main structure includes a needle shaft, a needle tube and an elastic member (not shown in the figure) arranged between the needle shaft and the needle tube. When the splicing male part 120 cooperates with the splicing female part 210, the conductive contact piece 211 contacts and abuts against the needle shaft of the probe 1212; and due to the existence of the elastic member, the needle shaft will always be tightly held 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, and therefore the utility model will not be described again).

[0044] Preferably, the conductive contact piece 211 is of 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 electrical conductivity and heat dissipation performance, and the gold plating on the surface of the conductive contact piece 211 and the needle shaft can better improve its corrosion resistance, oxidation resistance, mechanical properties and electrical properties.

[0045] In summary, the modularized heat dissipation fan group of the utility model can be conveniently modularized assembled according to the use requirement, and the problems of messy wiring and difficult wiring are solved, so that the assembly efficiency is improved.

[0046] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
