Description

Technical Field

[0001] The utility model relates to a fan, in particular to a fan with a magnetic quick-release structure. Background Art

[0002] Small fans used in electronic devices, also known as cooling fans, are important components within electronic devices. Their primary function is to draw in cool air from the outside and expel hot air, further improving cooling efficiency and maintaining a reasonable operating temperature within the electronic device.

[0003] If the heat generated by the processor on the mainboard of an electronic device cannot be discharged when it is running, the internal temperature of the electronic device may be too high, affecting the performance of the electronic device and even causing damage to the hardware of the electronic device.

[0004] Therefore, small fans are very important. They can reduce the risk of hardware overheating by directing the heat generated internally to the outside, thereby protecting the internal components of the electronic device and ensuring that they can operate at optimal performance, thereby extending the service life of the electronic device.

[0005] When a small fan used in a typical electronic device fails or is damaged, it is difficult to disassemble the fan components for replacement or repair due to its small size, so the entire small fan must be replaced. This also increases the amount of small fans discarded.

[0006] Therefore, how to improve the small fan so that it is easy to disassemble, repair or replace, and reduce the amount of waste of small fans is the problem to be solved by this application. Utility Model Content

In this figure, the electrical connector 3 is a spring-loaded (POGO) pin connector.

[0047] The quick-release plate 4 is mounted on the support plate 11 and has a carrier plate 41 having the same shape as the support portion 12. The front of the carrier plate 41 has a central axis 42 with an axial hole 421. The axial hole 421 is used to mount the hub and bearing (not shown) of the fan blade (not shown). Furthermore, a connecting shaft 43 is provided on the back of the carrier plate 41. The connecting shaft 43 is assembled to the inner diameter of the assembly portion 13. Furthermore, a protrusion 44 is provided on one side of the carrier plate 41. The protrusion 44 has a positioning hole 441 that is positioned to engage with the first engaging portion 14.

The protrusion 45 has a plurality of through-holes 46 for the elastic conductive pins 31 to pass through, thereby electrically connecting the elastic conductive pins 31 to the adapter substrate 6. The front of the protruding plate 45 has a second engaging portion 47 for engaging the transfer substrate 6, and the back of the protruding plate 45 has a receiving portion 48 for mounting at least one set of magnetic elements 5. In this figure, the second engaging portion 47 is in an inverted hook shape.

[0048] The magnetic element 5 is mounted in the mounting portion 15 and the receiving portion 48. When the quick release plate 4 is assembled with the support plate 11, the magnetic element 5 can attract the quick release plate 4 to the support plate 11, thereby achieving rapid disassembly and installation. In this embodiment, the magnetic element 5 is a magnet.

[0049] The adapter substrate 6 is mounted on the front surface of the quick-release plate 4. It has the same shape as the circuit board 2 and includes a second plate 61 positioned on the carrier plate 41. The second plate 61 has a second opening 62 for the central axis 42 to pass through.
