Description

Technical fields:

[0001] This utility model relates to the technical field of fan products, and specifically to a 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:

[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] SeeFigures 1-10 As shown, a quick-release cascaded fan includes at least two fan bodies 1 docked together and a locking conductive member 2 for locking two adjacent fan bodies 1 together and forming an electrical connection. After the locking conductive member 2 connects at least two fan bodies 1 together and forms an electrical connection, 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.

[0030] 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; wherein, the two ends of the locking conductive member 2 pass through the first slot 11 and the second slot 12 of two adjacent fan bodies to be inserted and fixed with the first connector 13 and the second connector 14, and the first connector 13 and the second connector 14 are connected through the locking conductive member 2, and the fan body 1 is also provided with an ejection button 3 for driving one end of the locking conductive member 2 to tilt up. 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. Then, a locking conductive member 2 is inserted into the first slot 11 and the second slot 12. The two ends of the locking conductive member 2 pass through the first slot 11 and the second slot 12 of the two adjacent fan bodies respectively to be inserted and fixed with the first connector 13 and the second connector 14, forming a physical structure lock, so that the two fan bodies 1 are locked together and will not accidentally detach. The first connector 13 and the second connector 14 are connected through the locking conductive member 2, so that the two fan bodies 1 are electrically connected, thereby forming a quick-release fan system. When it is necessary to disassemble the two adjacent fan bodies 1, press or push the exit button 3 directly. The exit button 3 drives one end of the locking conductive member 2 to lift up. At this time, one end of the locking conductive member 2 can be clamped by hand or tool to pull it outward, so that the locking conductive member 2 can be pulled out relative to the first slot 11 and the second slot 12. It achieves quick disassembly and is extremely convenient to use. This invention solves the problem described in the background art: 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.

[0031] The following provides a detailed description of the assembly structure of the eject button 3, the fan body 1, and the locking conductive component 2.

[0032] The eject button 3 is rotatably connected to the fan body 1. One end of the eject button 3 contacts the lower end of the locking conductive member 2, and the other end of the eject button 3 protrudes from the surface of the fan body 1. When the other end of the eject button 3 is pressed, one end of the eject button 3 is lifted, thereby lifting one end of the locking conductive member 2 to protrude from the surface of the fan body 1. In actual use, after the locking conductive member 2 is inserted into place, both ends of the locking conductive member 2 are respectively inserted and fixed to the first connector 13 and the second connector 14. At this time, both ends of the locking conductive member 2 also partially protrude from the first connector 13 and the second connector 14. At this time, the lower side of one end of the locking conductive member 2 abuts against one end of the eject button 3. At this time, through the lever principle, the other end of the eject button 3 protrudes from the bottom to the surface of the fan body 1. When disassembly is required, pressing the other end of the eject button 3, through the lever principle, lifts one end of the eject button 3, thereby lifting one end of the locking conductive member 2 to protrude from the surface of the fan body 1, thus facilitating quick disassembly.

[0033] The structure of the exit key 3 will be explained in detail below.

[0034] The eject button 3 includes a pivot portion 31 that is rotatably connected to the fan body 1, a raised portion 32 integrally formed at one end of the pivot portion 31, and a button portion 33 integrally formed at the other end of the pivot portion 31. The button portion 33 protrudes from the bottom up through the movable hole 101 of the fan body 1 and protrudes from the surface of the fan body 1. The raised portion 32 abuts against the lower side of one end of the locking conductive member 2. After the eject button 3 is assembled with the fan body 1, it forms a lever structure.

[0035] In this embodiment, the eject button 3 is an insulating component, such as a plastic component.

[0036] The pivot part 31 has a through hole 311 in the middle. The screw 34 passes through the through hole 311 and is screwed to the fan body 1. The pivot part 31 can rotate relative to the screw 34. Its assembly structure is extremely simple.

[0037] In another embodiment, a torsion spring is provided between the exit button 3 and the fan body 1, and the button portion 33 protrudes from the surface of the fan body 1 under the elastic force of the torsion spring. In the non-pressed state, the button portion 33 always protrudes from the surface of the fan body 1, which also facilitates the assembly of the locking conductive component 2.

[0038] To reduce the excessive protrusion of the button portion 33 beyond the surface of the fan body 1, which would affect normal use, the following design was made: a circular groove 102 is provided on the surface of the fan body 1, and the upper end of the movable hole 101 passes through the bottom surface of the circular groove 102. In other words, the circular groove 102 is equivalent to making the surface of the fan body 1 lower, but it does not affect the height of the button portion 33 protruding relative to the circular groove 102, ensuring that the travel of the button portion 33 when pressed is long enough, and reducing the excessive protrusion of the button portion 33 beyond the surface of the fan body 1, which would affect normal use.

[0039] The structure of the locking conductive element 2 will be described in detail below.

[0040] The locking conductive component 2 is a circuit board. The lower ends of both sides of the locking conductive component 2 are respectively formed with a first pair of insertion portions 21 and a second pair of insertion portions 22. Each of the first pair of insertion portions 21 has a first metal piece 211 on both sides, and each of the second pair of insertion portions 22 has a second metal piece 221 on both sides, corresponding to and communicating with the first metal piece 211. The first pair of insertion portions 21 and the second pair of insertion portions 22 are respectively inserted into the first connector 13 and the second connector 14, and are tensioned and positioned. This not only ensures the stability of the conductivity but also increases the insertion and extraction force of the locking conductive component 2, preventing accidental dislodgement. Furthermore, the first metal piece 211 of the first pair of insertion portions 21 is conductive to the first terminal 131 inside the first connector 13, and the second metal piece 221 of the second pair of insertion portions 22 is conductive to the second terminal 141 inside the second connector 14, thereby electrically connecting the first connector 13 and the second connector 14.

[0041] The first connector 13 includes a first insulating seat 132 with a first mating groove 133, in which a first terminal 131 is exposed. After the first mating part 21 is inserted into the first mating groove 133 and positioned, it can increase the insertion and extraction force of the locking conductive member 2 and prevent the locking conductive member 2 from accidentally coming out. The second connector 14 includes a second insulating seat 142 with a second mating groove 143, in which a second terminal 141 is exposed. After the second mating part 22 is inserted into the second mating groove 143 and positioned, it can increase the insertion and extraction force of the locking conductive member 2 and prevent the locking conductive member 2 from accidentally coming out.

[0042] Each of the first terminals 131 is provided with two opposing first elastic clamping arms 134 and second elastic clamping arms 135. The first pair of insertion parts 21 is inserted between the first elastic clamping arms 134 and second elastic clamping arms 135 and is clamped and positioned by the first elastic clamping arms 134 and second elastic clamping arms 135. This not only ensures the stability of the conduction, but also increases the insertion and extraction force of the locking conductive element 2, preventing the locking conductive element 2 from accidentally coming out. In addition, the first elastic clamping arms 134 and second elastic clamping arms 135 are respectively connected to the first metal plates 211 on the front and back sides of the first pair of insertion parts 21, realizing double-sided conduction and improving the conduction quality.

[0043] Each of the second terminals 141 is provided with two opposing third elastic clamping arms 144 and fourth elastic clamping arms 145. The second pair of insertion parts 22 are inserted between the third elastic clamping arms 144 and fourth elastic clamping arms 145 and are clamped and positioned by the third elastic clamping arms 144 and fourth elastic clamping arms 145. This not only ensures the stability of the conduction, but also increases the insertion and extraction force of the locking conductive element 2, preventing the locking conductive element 2 from accidentally coming out. In addition, the third elastic clamping arms 144 and fourth elastic clamping arms 145 are respectively connected to the second metal plates 221 on the front and back sides of the second pair of insertion parts 22, realizing double-sided conduction and improving the conduction quality.

[0044] The upper surface of the locking conductive element 2 is completely submerged in the first slot 11 and the second slot 12, so that the upper surface of the locking conductive element 2 is lower than or flush with the upper surface of the fan body 1, which will not affect the normal use of the fan body.

[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 conductive element 2 is then inserted into the first slot 11 and the second slot 12. Both 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 fixed with the first connector 13 and the second connector 14, forming a physical locking structure. This locks the two fan bodies 1 together and prevents accidental detachment. The first connector 13 and the second connector 14 are connected via the locking conductive element 2, making the two fan bodies 1 electrically connected, thus forming a quick-release fan system. When it is necessary to disassemble the two adjacent fan bodies 1, simply press or push the eject button 3. The eject button 3 causes one end of the locking conductive element 2 to lift up. At this time, one end of the locking conductive element 2 can be gripped with a hand or tool and pulled outwards, allowing the locking conductive element 2 to be pulled out relative to the first slot 11 and the second slot 12. This quick-release design is extremely convenient to use.

[0046] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model.
