Description

Technical fields:

[0001] This invention relates to the field of fan technology, and specifically to a quick-release fan structure that can be assembled at any angle. 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 greatly 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, it is essential to implement heat dissipation measures for electronic products.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figure 1-8 As shown, a quick-release fan structure that can be assembled at any angle includes a fan bracket 1, a fan 2, and a housing 3. The fan bracket 1, the fan 2, and the housing 3 are three independent entities that can be relatively disassembled and installed.

[0028] The fan bracket 1 is provided with a first strong magnet 11 and a first connector 12; the fan 2 includes a base 21, a motor assembly 22 and a PCB board 23 mounted on the base 21, and fan blades 24 rotatably mounted on the motor assembly 22 via a rotating shaft. The bottom of the base 21 is provided with a second strong magnet 25 adapted to the first strong magnet 11, and the bottom of the base 21 is also provided with a second connector 26 adapted to the first connector 12 and electrically connected to the PCB board 23. The fan 2 is mounted on the fan bracket 1 at any angle through the base 21. The first strong magnet 11 and the second strong magnet 25 are magnetically attracted and fixed to fix the fan 2 on the fan bracket 1, and the first connector 12 and the second connector 26 are in contact and conductive. In other words, the fan bracket 1 and the fan 2 in this invention are magnetically fixed together by the first strong magnet 11 and the second strong magnet 25, thereby fixing the base 21 of the fan 2 to the fan bracket 1. There is no snap-fit ​​structure between them, making disassembly and assembly very simple and achieving quick disassembly. Furthermore, since the fan bracket 1 and the base 21 of the fan 2 are magnetically fixed without snap-fit ​​structure, and are electrically conductive through the contact between the first connector 12 and the second connector 26, there is no limitation on the angle at which the fan 2 is installed in the fan bracket 1. The fan 2 can be installed in the fan bracket 1 at any angle, making installation more convenient and efficient, thereby enhancing the market competitiveness of this invention.

[0029] The assembly structure of the first connector 12 and the second connector 26 will be described in detail below.

[0030] The first connector 12 includes an adapter plate 121 and several annular conductive plates 122 arranged on the adapter plate 121; the second connector 26 is a spring-loaded pin connector, which has several spring-loaded pins 261, each corresponding to one of the annular conductive plates 122. In this structure, the first connector 12 and the second connector 26 are directly connected by contact, requiring no insertion, making assembly extremely convenient. Furthermore, the annular conductive plates 122 can make contact with the spring-loaded pin connector inserted at any angle, forming an electrical connection.

[0031] Alternatively, the second connector may include an adapter plate and several annular conductive plates disposed on the adapter plate; the first connector may be a spring pin connector having several spring pins that engage with the annular conductive plates. In this configuration, the first and second connectors are directly connected by contact, requiring no insertion and making assembly extremely convenient. Furthermore, the annular conductive plates can make contact with spring pin connectors inserted at any angle and form an electrical connection.

[0032] Both the first strong magnet 11 and the second strong magnet 25 are circular and coaxially arranged with the rotating shaft 241 in the fan blade 24. This ensures that after the fan 2 and the fan bracket 1 are assembled, the first strong magnet 11 and the second strong magnet 25 can correspond to each other and be magnetically attracted and fixed together. Both the first strong magnet 11 and the second strong magnet 25 are strong magnets, which can ensure that the base 21 of the fan 2 is stably installed on the fan bracket 1 and is not easy to detach.

[0033] The base 21 is provided with a through hole 210 that passes through the upper and lower end faces. The second connector 26 is welded and fixed to the bottom surface of the PCB board 23. The second connector 26 is also embedded in the through hole 210, and the spring pin 261 of the second connector 26 extends out of the bottom surface of the base 21 so as to contact and conduct with the first connector.

[0034] To ensure the alignment accuracy, guidance, and stability of the fan 2 base 21 and the fan bracket 1, the following design was implemented:

[0035] The fan bracket 1 is provided with a guide ring 13, and the first strong magnet 11 is sleeved around the guide ring 13. The bottom of the base 21 is provided with a guide groove 211 and a first fixing groove 212 located around the guide groove 211. The second strong magnet 25 is embedded and fixed in the first fixing groove 212 to ensure the stability of the assembly. Preferably, the second strong magnet 25 and the bottom of the first fixing groove 212 can also be glued together to further improve the stability of the assembly structure and prevent the second strong magnet 25 from falling out of the second fixing groove 212. During assembly, when the base 21 is installed on the fan bracket 1, the upper end of the guide ring 13 is also embedded in the guide groove 211 at the bottom of the base 21 to position the base 21 on the fan bracket 1, which plays a guiding role and achieves the purpose of accurate alignment. The first strong magnet 11 and the second strong magnet 25 are connected and magnetically fixed to ensure the stability of the assembly structure between the base 21 and the fan bracket 1. Furthermore, the upper end of the guide ring 13 is also provided with a guide slope 131, which has a guiding function, so that the upper end of the guide ring 13 can be better nested with the guide groove 211, which can further improve the assembly efficiency.

[0036] Specifically, the fan bracket 1 is further provided with a second fixing groove 14 around the guide ring 13. The first strong magnet 11 is embedded and fixed in the second fixing groove 14 to further ensure the stability of the assembly and to stably install the first strong magnet 11 on the fan bracket 1. Preferably, the first strong magnet 11 is also glued to the bottom of the second fixing groove 14 to further improve the stability of the assembly structure and prevent the first strong magnet 11 from falling out of the second fixing groove 14. The fan bracket 1 is further provided with a third fixing groove 15 around the second fixing groove 14. The adapter plate 121 is fixedly installed in the third fixing groove 15, which can limit the adapter plate 121 to a certain extent. The adapter plate 121 is also locked to the fan bracket 1 with screws to ensure the stability of the assembly structure and prevent the adapter plate 121 from falling out of the fan bracket 1.

[0037] In addition, the fan bracket 1 is provided with a cable tray 16 on the outside of the third fixing slot 15. The cable 17 connected to the adapter plate 121 is placed in the cable tray 16, and the third connector 171 at the end of the cable 17 extends out of the fan bracket 1. A cable baffle 161 is provided at the port of the cable tray 16 to confine the cable 17 in the cable tray 16. This has the purpose of binding the cable 17 in the cable tray 16, which can ensure the neatness of the cable routing and prevent the cable from becoming messy.

[0038] The fan bracket 1 is also provided with a housing 3, which has a window 31. The fan blade 24 is placed in the window 31, and the housing 3 has the function of protecting the fan blade 24.

[0039] The outer casing 3 has a convex ring 32 formed in the middle and a connecting post 33 located outside the convex ring 32. The window 31 is formed inside the convex ring 32. The connecting post 33 has a threaded groove 331. The lower end of the convex ring 32 is also provided with a limiting groove 321. The fan bracket 1 is partially embedded in the limiting groove 321 for positioning. The fan bracket 1 is provided with a positioning groove 101 and a countersunk hole 102 that passes through the positioning groove 101. The end of the connecting post 33 is embedded in the positioning groove 101. A screw passes through the countersunk hole 102 and is screwed into the threaded groove 331, so that the outer casing 3 is fixed on the fan bracket 1.

[0040] In summary, the fan bracket 1 and the fan 2 in this invention are magnetically fixed together by a first strong magnet 11 and a second strong magnet 25, thereby fixing the base 21 of the fan 2 to the fan bracket 1. There is no snap-fit ​​structure between them, making disassembly and assembly very simple and enabling quick disassembly. Furthermore, because the fan bracket 1 and the base 21 of the fan 2 are magnetically fixed without snap-fit ​​structures, and are electrically conductive through the contact between the first connector 12 and the second connector 26, there is no limitation on the angle at which the fan 2 is installed in the fan bracket 1. This allows the fan 2 to be installed at any angle in the fan bracket 1, making installation more convenient and efficient, thus enhancing the market competitiveness of this invention.
