Description

Technical fields:

[0001] This utility model relates to the field of fan product technology, and specifically to a cascaded fan that can be quickly disassembled. Background technology:

[0002] With the development of the electronics industry, electronic products are gradually evolving towards higher performance, higher frequency, higher speed, and thinner designs. As the performance of electronic products continues to improve and their processing speeds increase, the processing speed of their internal chipsets also increases, along with the number of chips. Consequently, the heat generated by these chips during operation also increases. If this heat is not dissipated in time, it will significantly affect the performance of electronic products, reducing their processing speed. With the continuous accumulation of heat, it may even burn out the electronic products. Therefore, heat dissipation is essential for electronic products, and cooling fans play a crucial role in this process. In practical applications, in some situations, multiple fans need to be cascaded to form a fan system.

[0003] Patent application number 202410888015.X discloses a magnetic fan assembly, comprising two or more fan bodies. Adjacent fan bodies are magnetically connected via a magnetic assembly. The magnetic assembly includes a first magnetic assembly independent of the fan body and a second magnetic assembly disposed on the fan body. Adjacent fan bodies are joined together by the magnetic attraction of the first and second magnetic assemblies. The first magnetic assembly is equipped with a magnet, and the second magnetic assembly is equipped with a magnet or a magnetic material. Because the first magnetic assembly is independent of the fan body, it can directly contact and connect with the second magnetic assembly, and the magnetic attraction effect is not affected by the plastic insulation of the fan body, resulting in a stronger magnetic force and a more secure connection. Furthermore, since the first magnetic assembly is equipped with a magnet and the second magnetic assembly is made of a magnetic material, and the magnetic material has no magnetic pole direction, the magnet can magnetize and attract the magnetic material. The magnetic material can be directly configured without identifying its orientation, significantly improving assembly efficiency.

[0004] However, the magnetic connection between adjacent fan units has some problems: if the magnetic force of the magnetic assembly is too strong, although it can ensure a stable connection between adjacent fan units, it will make it difficult to separate adjacent fan units, and it cannot achieve the quick-release function; when the external force is greater than the magnetic force, it will also cause adjacent fan units to separate / shift, and it cannot achieve the locking function; in addition, if the magnetic force of the magnetic assembly is too weak, it will cause the connection between adjacent fan units to be unstable, causing great inconvenience to the user.

[0005] In view of the above, the inventors propose the following technical solution. Utility model content:

The first positioning groove and the second positioning groove are respectively engaged and positioned on the first positioning post and the second positioning post, and the positioning part is tensioned and positioned between the first positioning post and the second positioning post.

[0014] Furthermore, in the above technical solution, the number of locking components is at least two, which are respectively inserted into the upper and lower parts of two adjacent fan bodies.

[0032] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0033] See Figure 1-14 As shown, a cascaded fan that can be quickly disassembled includes at least two fan bodies 1 that are docked together and a locking member 2 for locking two adjacent fan bodies 1 together and forming an electrical connection. After at least two fan bodies 1 are connected together and electrically connected, a fan system can be formed to quickly dissipate heat from electronic components (such as chips) in electronic products, ensure the working quality of electronic products, improve the service life of electronic products, and meet different usage requirements.

[0034] Specifically, the fan body 1 has a first slot 11 and a second slot 12 on both sides, and a first connector 13 and a second connector 14 are respectively provided in the first slot 11 and the second slot 12. A first locking groove 15 and a second locking groove 16 are respectively provided on the side of the first slot 11 and the second slot 12. The locking member 2 has a first conductive member 201 and a second conductive member 202 that are electrically connected to each other at both ends. The locking member 2 has a first latch 203. The two ends of the locking member 2 are respectively inserted and positioned in the first slot 11 and the second slot 12 of two adjacent fan bodies 1. The first conductive member 201 and the second conductive member 202 are electrically connected to the first connector 13 and the second connector 14, so that the first connector 13 and the second connector 14 are electrically connected. The first latch 203 is locked with the first locking groove 15 and the second locking groove 16 to prevent the locking member 2 from coming out of the first and second slots. In other words, this utility model connects at least two fan bodies 1 together, with the first slot 11 of one fan body 1 close to the second slot 12 of the other fan body 1. A locking member 2 is then inserted into the first slot 11 and the second slot 12. The first latch 203 of the locking member 2 engages with the first locking groove 15 and the second locking groove 16 to prevent the locking member 2 from dislodging from the first and second slots, thus locking the two fan bodies 1 together. The connection is extremely stable, preventing adjacent fan bodies 1 from detaching. Simultaneously, the first conductive element 201 and the second conductive element 202 at both ends of the locking member 2 are electrically connected to the first connector 13 and the second connector 14, respectively, thus making adjacent fan bodies 1 electrically connected, forming a quick-release fan system. When it is necessary to disassemble adjacent fan bodies 1, the first latch 203 of the locking member 2 is directly driven out of the first locking groove 15 and the second locking groove 16, allowing the locking member 2 to be directly dislodged from the first and second slots, completing the separation of the adjacent fan bodies 1 and achieving quick disassembly, making it extremely convenient to use.

[0035] The structure of the locking element 2 is described in detail below:

[0036] The locking component 2 includes a positioning insert plate 21 and a first elastic locking arm 22 integrally connected to the rear side of the positioning insert plate 21 and capable of elastic deformation relative to the positioning insert plate 21. The first elastic locking arm 22 has a first latch 203 on its rear side. The first conductive element 201 and the second conductive element 202 are disposed at both ends of the front side of the positioning insert plate 21. In specific use, the two ends of the positioning insert plate 21 are inserted into the first locking groove 15 and the second locking groove 16 to achieve horizontal positioning. The first elastic locking arm 22 is pressed between two adjacent fan bodies 1 and compressed, so that the first elastic locking arm 22 forms an elastic force away from the positioning insert plate 21. Under the action of this elastic force, the first latch 203 on the rear side of the first elastic locking arm 22 is locked and fixed with the first locking groove 15 and the second locking groove 16, thereby achieving vertical locking. When unlocking is required, simply press the first elastic locking arm and move it toward the positioning plate 21. This will cause the first latch 203 on the rear side of the first elastic locking arm 22 to disengage from the first locking groove 15 and the second locking groove 16, thereby achieving the end of unlocking and further improving the efficiency of disassembly.

[0037] In this embodiment, there is one first latch 203, and the first locking groove 15 and the second locking groove 16 are joined to form a complete locking groove, with the first latch 203 pressed into the first locking groove 15 and the second locking groove 16; or, there are two first latches 203, which are pressed into the first locking groove 15 and the second locking groove 16 respectively. This embodiment, as a preferred embodiment, uses a scheme where the first latch 203 is one, and the first locking groove 15 and the second locking groove 16 are joined to form a complete locking groove, with the first latch 203 pressed into the first locking groove 15 and the second locking groove 16. This structure is the simplest and the easiest to install.

[0038] The lower end of the first elastic locking arm 22 is integrally connected to the lower end of the positioning insert plate 21 to form a V-shaped structure. That is, the first elastic locking arm 22 is inclined relative to the positioning insert plate 21 to have better elastic deformation capability.

[0039] The first conductive element 201 and the second conductive element 202 are both gold fingers (i.e., metal sheets distributed vertically), which are fixed on the PCB board 23 and are conductive through the PCB board 23. Their structure is simpler and easier to fix on the positioning plate 21. The PCB board 23 is fixed to the front side of the positioning plate 21. The first connector 13 and the second connector 14 are both elastic pin connectors. After the first conductive element 201 and the second conductive element 202 are respectively inserted into the first slot 11 and the second slot 12 along with the positioning plate 21, the first conductive element 201 and the second conductive element 202 respectively form an elastic conductive connection with the first connector 13 and the second connector 14, and the connection is more stable.

[0040] The assembly structure of the PCB board 23 and the positioning insert 21 is as follows: The positioning insert 21 has a mounting groove 211 on the front side, and the PCB board 23 is embedded and positioned in the mounting groove 211 for positioning and limiting, and then locked by screws to ensure that the assembly structure is extremely stable.

[0041] To make the locking member 2 more stable with the two adjacent fan bodies 1, the following design is also made: the first slot 11 and the second slot 12 are respectively provided with horizontally distributed first positioning posts 111 and second positioning posts 121; the lower end of the locking member 2 is provided with a first positioning groove 204 and a second positioning groove 205 and a positioning part 206 located between the first positioning groove 204 and the second positioning groove 205. The first positioning groove 204 and the second positioning groove 205 are respectively engaged and positioned on the first positioning post 111 and the second positioning post 121, which achieves another horizontal limit and positioning, and the positioning part 206 is tensioned and positioned between the first positioning post 111 and the second positioning post 121, which achieves the purpose of tensioning and positioning.

[0042] The number of locking components 2 is at least two, which are respectively inserted into the upper and lower parts of two adjacent fan bodies 1, further ensuring that the locking components 2 and the two adjacent fan bodies 1 are more stable.

[0043] At least one fan body 1 has an external connector 3 provided in a first slot 11 or a second slot 12. The external connector 3 is also connected to a first connector 13 in the first slot 11 or a first connector 13 in the second slot 12. The external connector 3 can be connected to a data cable for inputting power signals and control signals.

[0044] Specifically, the external connector 3 includes an insulating locking plate 31, a circuit board 32 fixed to one side of the insulating locking plate 31, a cover plate 33 disposed on the insulating locking plate 31 and partially covering the circuit board 32, and a second elastic locking arm 34 integrally connected to the other side of the insulating locking plate 31. The second elastic locking arm 34 is provided with a second latch 341 on its rear side. The second latch 341 is locked and fixed with the first locking groove 15 or the second locking groove 16, which can also ensure that the external connector 3 is stably installed on the fan body 1. The cover plate 33 has a socket 331. One end of the circuit board 32 is provided with a first terminal 321 exposed in the socket 331. The other end of the circuit board 32 is provided with a second terminal 322 that is connected to the first connector 13 or the second connector 14.

[0045] In summary, this utility model connects at least two fan bodies 1 together, with the first slot 11 of one fan body 1 close to the second slot 12 of the other fan body 1. A locking member 2 is then inserted into the first slot 11 and the second slot 12. The first latch 203 of the locking member 2 engages with the first locking groove 15 and the second locking groove 16 to prevent the locking member 2 from dislodging from the first and second slots, thus locking the two fan bodies 1 together. The connection is extremely stable, preventing adjacent fan bodies 1 from detaching. Simultaneously, the first conductive element 201 and the second conductive element 202 at both ends of the locking member 2 are electrically connected to the first connector 13 and the second connector 14, respectively, thus creating electrical connection between adjacent fan bodies 1 and forming a quick-release fan system. When it is necessary to disassemble adjacent fan bodies 1, the first latch 203 of the locking member 2 is directly disengaged from the first locking groove 15 and the second locking groove 16, allowing the locking member 2 to be directly disengaged from the first and second slots, thus separating the adjacent fan bodies 1 and achieving quick disassembly. This makes it extremely convenient to use.
