Description

Technical fields:

[0001] This utility model relates to the field of fan product technology, and specifically to a press-to-pop quick-release cascaded fan. 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:

[0010] Furthermore, in the above technical solution, the locking conductive element is completely submerged in the first slot and the second slot, and the end face of the locking conductive element is lower than the surface of the fan body.

[0011] Furthermore, in the above technical solution, the fan body includes: an integrated frame with a first mounting position in its middle; a motor assembly mounted in the first mounting position; and fan blades mounted on the motor assembly and driven by the motor assembly to rotate. The four corners of the frame are each provided with mounting slots and end caps fixed to the ports of the mounting slots. Specifically, the two mounting slots on the left side each have a first PCB board, to which the first SD card slot is fixed and connected; the two mounting slots on the right side each have a second PCB board, to which the second SD card slot is fixed and connected.

The external connector is a connecting wire or a PFC flexible board or a plug with a wire. The external connector has a third pair of protruding parts that are the same shape as the SD card. The third pair of protruding parts are inserted into the first SD card slot or the second SD card slot and form an electrical connection.

[0013] Furthermore, in the above technical solution, the external connector includes an insulating shell, a circuit board secured inside the insulating shell by screws, and an insulating cover plate mounted on the insulating shell and covering the circuit board. The circuit board has the third pair of plugs exposed outside the insulating shell, and the third pair of plugs has a third conductor. A mating interface is formed between the insulating shell and the insulating cover plate, and a fourth conductor of the circuit board is exposed in the mating interface.

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figure 1-8 As shown, a push-to-pop type quick-release cascaded fan includes at least two fan bodies 1 docked together; when the at least two fan bodies 1 are connected together and electrically connected, they can form a fan system 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.

[0026] Specifically, the fan body 1 has a first slot 11 and a second slot 12 on both sides, and a first SD card holder 13 and a second SD card holder 14 are respectively disposed in the first slot 11 and the second slot 12. It also includes a locking conductive member 2 adapted to the first SD card holder 13 and the second SD card holder 14. The locking conductive member 2 has a first pair of insertion portions 21 and a second pair of insertion portions 22 protruding downwards and having the same shape as an SD card on both sides. The first conductor 211 on the first pair of insertion portions 21 and the second conductor 221 on the second pair of insertion portions 22 are connected in a one-to-one manner. During assembly, after the locking conductive member 2 is inserted into the first slot 11 and the second slot 12 of two adjacent fan bodies 1, the first pair of insertion portions 21 and the second pair of insertion portions 22 are respectively inserted into the first SD card holder 13 and the second SD card holder 14. The locking conductor 2 is engaged and locked in place, thereby fixing two adjacent fan bodies 1 together, and the connection structure is stable. The first conductor 211 and the second conductor 221 are respectively connected to the first SD card slot 13 and the second SD card slot 14, so that the first SD card slot 13 and the second SD card slot 14 are electrically connected, thereby connecting the two adjacent fan bodies 1 to the end of the cascade. When the locking conductor 2 is pressed, the first SD card slot 13 and the second SD card slot 14 respectively drive the first pair of plugs 21 and the second pair of plugs 22 to pop outward, so that the upper end of the locking conductor 2 protrudes from the surface of the fan body 1. At this time, the locking conductor 2 can be pulled out by hand or tool by clamping one end of the locking conductor 2, so that the locking conductor 2 can be pulled out relative to the first slot 11 and the second slot 12, which achieves quick release and is extremely convenient to use. In other words, this invention 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 conductive element 2 is then inserted into the first slot 11 and the second slot 12. The two ends of the locking conductive element 2 pass through the first slot 11 and the second slot 12 of the two adjacent fan bodies to be inserted and fixed with the first SD card holder 13 and the second SD card holder 14, forming a physical locking structure. This structure is extremely stable, ensuring that the two fan bodies 1 are locked together and will not accidentally detach. The first SD card holder 13 and the second SD card holder 14 are electrically connected through the locking conductive element 2, enabling the two fan bodies 1 to conduct electricity. This forms a quick-release fan system. When it is necessary to disassemble two adjacent fan bodies 1, simply press the locking conductive part 2. The first SD card slot 13 and the second SD card slot 14 will respectively drive the first pair of insertion parts 21 and the second pair of insertion parts 22 to pop outward, so that the upper end of the locking conductive part 2 protrudes from the surface of the fan body 1. At this time, one end of the locking conductive part 2 can be clamped by hand or tool to pull it outward, so that the locking conductive part 2 can be pulled out relative to the first slot 11 and the second slot 12. This achieves quick disassembly and is extremely convenient to use. It solves the problem described in the background art that when adjacent fan bodies are fixed by magnetic adsorption, it is difficult to disassemble due to excessive magnetic force and the connection is unstable due to insufficient magnetic force.

[0027] The first SD card slot 13 and the second SD card slot 14 described above are both conventional SD card slots in the prior art, and both have the following functions: both the first SD card slot 13 and the second SD card slot 14 can lock and conduct the inserted SD card, and pressing the SD card can drive the first SD card slot 13 and the second SD card slot 14 to work, which can eject the SD card for removal. The internal structure of the first SD card slot 13 and the second SD card slot 14 (such as the structure for locking the inserted SD card and the structure for ejecting the SD card by pressing) can adopt the internal structure of a removable SD card slot disclosed in CN220155813U or a Micro SD card slot with anti-discard function disclosed in CN217009754U, both of which can achieve the above functions.

[0028] The locking conductive component 2 is a PCB board. The PCB board is printed with a first gold finger and a second gold finger, which serve as a first conductor 211 and a second pair of insertion portions 22. The PCB board is also printed with electronic circuits that connect the first gold finger and the second gold finger. Its structure is extremely simple and can not only achieve the locking function, but also the conductive function.

[0029] The corner of the fan body 1 is set in an arc shape, so that a gap 10 is formed between two adjacent fan bodies 1 that gradually decreases from the outside to the inside. The upper end of the locking conductive member 2 is partially exposed in the gap 10, which makes it convenient for the user to press the upper part of the locking conductive member 2 so as to drive the first SD card slot 13 and the second SD card slot 14 to work, and the locking conductive member 2 is ejected by the first SD card slot 13 and the second SD card slot 14.

[0030] The locking conductive element 2 is completely submerged in the first slot 11 and the second slot 12. The end face of the locking conductive element 2 is lower than the surface of the fan body 1, which can reduce the risk of accidentally knocking out the locking conductive element 2.

[0031] The fan body 1 includes: a frame 15 with an integral structure, a motor assembly 16 and fan blades 17, wherein the frame 15 is integrally molded from plastic.

[0032] The frame 15 has a first mounting position 151 in the middle; the motor assembly 16 is mounted in the first mounting position 151; the fan blade 17 is mounted on the motor assembly 16 and can be driven by the motor assembly 16 to rotate.

[0033] The frame 15 has mounting slots 152 at each of its four corners and end caps 153 fixed to the ports of the mounting slots 152. The two mounting slots 152 on the left are connected to the first slot 11 and each of the two mounting slots 152 on the left is provided with a first PCB board 154, which is fixed with the first SD card holder 13. The two mounting slots 152 on the right are provided with a second PCB board 155 and are connected to the second slot 12. The second PCB board 155 is fixed with the second SD card holder 14. During installation, the end cap 153 is opened relative to the mounting slot 152, and the first PCB board 154, which is fixed with the first SD card holder 13, is installed in the two mounting slots 152 on the left side. The first SD card holder 13 corresponds to the first slot 11. Then, the end cap 153 is installed to cover the mounting slot 152 on the left side. Similarly, the second PCB board 155, which is fixed with the second SD card holder 14, is installed in the two mounting slots 152 on the right side. The second SD card holder 14 corresponds to the second slot 12. Then, the end cap 153 is installed to cover the mounting slot 152 on the right side. The assembly structure is simple, and the frame 15 has a stable structure and high strength.

[0034] In some embodiments, an external connector 3 is inserted into the first slot 11 or the second slot 12. The external connector 3 connects to a wire, a PFC flexible board, or a plug with a wire. In this embodiment, it is preferred that the external connector 3 connects to a plug with a wire, that is, the plug with a wire is inserted into the external connector 3 to achieve a connection.

[0035] The external connector 3 has a third pair of inserts 301 that protrude downwards and are the same shape as the SD card. The third pair of inserts 301 are inserted into the first SD card slot 13 or the second SD card slot 14 and form an electrical connection. They can also be locked and are easy to eject later, making them extremely convenient to use.

[0036] The specific structure of the external connector 3 is as follows:

[0037] The external connector 3 includes an insulating shell 31, a circuit board 32 secured to the insulating shell 31 by screws, and an insulating cover plate 33 mounted on the insulating shell 31 and covering the circuit board 32. The circuit board 32 has a third pair of plugs 301 exposed outside the insulating shell 31 and has a third conductor 302. A mating interface 30 is formed between the insulating shell 31 and the insulating cover plate 33. A fourth conductor of the circuit board 32 is exposed in the mating interface 30 and is electrically connected to the inserted plug.

[0038] The insulating shell 31 is provided with a recessed groove 311, and a limiting groove 312 that passes through the recessed groove 311 is also provided on the outside of the insulating shell 31. The circuit board 32 and the insulating cover plate 33 are embedded in the recessed groove 311 and locked by the first screw 313. The limiting protrusion 331 formed on the insulating cover plate 33 is inserted into the limiting groove 312, and its assembly structure is extremely stable.

[0039] In summary, this invention 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 conductive element 2 is then inserted into the first slot 11 and the second slot 12. The two ends of the locking conductive element 2 pass through the first slot 11 and the second slot 12 of the two adjacent fan bodies to be inserted and fixed with the first SD card holder 13 and the second SD card holder 14, forming a physical locking structure. This structure is extremely stable, locking the two fan bodies 1 together and preventing accidental detachment. The first SD card holder 13 and the second SD card holder 14 are electrically connected through the locking conductive element 2, enabling the two fan bodies 1 to conduct electricity. This forms a quick-release fan system. When it is necessary to disassemble two adjacent fan bodies 1, simply press the locking conductive part 2. The first SD card slot 13 and the second SD card slot 14 will respectively drive the first pair of insertion parts 21 and the second pair of insertion parts 22 to pop outward, so that the upper end of the locking conductive part 2 protrudes from the surface of the fan body 1. At this time, one end of the locking conductive part 2 can be clamped by hand or tool to pull it outward, so that the locking conductive part 2 can be pulled out relative to the first slot 11 and the second slot 12. This achieves quick disassembly and is extremely convenient to use. It solves the problem described in the background art that when adjacent fan bodies are fixed by magnetic adsorption, it is difficult to disassemble due to excessive magnetic force and the connection is unstable due to insufficient magnetic force.
