Description

Technical Field

[0001] This utility model relates to the field of computer keyboard technology, specifically to a wind-cooled magnetic axis keyboard. Background Technology

[0002] Magnetic axis keyboards are an emerging keyboard technology that utilizes electromagnetic principles and is based on the Hall effect. When the switch is pressed, the permanent magnet approaches the Hall sensor, and the change in magnetic field strength causes the Hall voltage to exceed the threshold, thus triggering the switch. It is a non-physical contact keyboard with a high degree of fast response and reset.

[0003] Currently, the key travel of mechanical keyboards on the market is around 2mm, but the best limit parameter of magnetic switch keyboards can reach 0.0005mm. However, even with these extreme parameters, the keyboard is relatively stable during the initial use, but during long-term use, the magnetic switch keyboard may start to heat up, thereby damaging the internal components of the keyboard. To address this, we have proposed an air-cooled magnetic switch keyboard. Utility Model Content

However, even with this limit parameter, the keyboard is relatively stable during the initial use, but during long-term use, the magnetic axis keyboard may start to heat up, thereby damaging the internal components of the keyboard. To achieve the above objectives, this utility model provides the following technical solution: a wind-cooled magnetic axis keyboard, comprising a keyboard bottom shell, a PCB back film fixedly connected to the bottom inner wall of the keyboard bottom shell, a PCB circuit board fixedly connected to the top of the PCB back film, a sound pad fixedly connected to the top of the PCB circuit board, a shaft pad fixedly connected to the top of the sound pad, a core pad fixedly connected to the top of the shaft pad, a positioning plate fixedly connected to the top of the core pad, and a keyboard body fixedly connected to the top of the positioning plate. A heat dissipation hole is provided on one side of the keyboard bottom shell. The PCB back film is a thermally conductive silicone pad, which is a sheet material with high thermal conductivity, made primarily of silicone and supplemented with various thermally conductive fillers. It can quickly transfer heat from the heat source to the heat dissipation device or other heat dissipation medium, effectively reducing the temperature of the heat source. It has a soft texture, can conform well to various irregular surfaces, fill the tiny gaps between the heat source and the heat dissipation device, and improve heat transfer efficiency.

[0005] More preferably, a connecting shell is fixedly connected to one side of the keyboard bottom shell, and two through holes are formed inside the connecting shell.

[0006] More preferably, the two through holes are symmetrically distributed inside the connecting shell, and cooling fans are movably connected inside the two through holes respectively. Through air cooling, the internal temperature of the keyboard can be effectively reduced, avoiding heat accumulation caused by long-term use. This helps to maintain the stable working state of the magnetic axis and other electronic components, reduce the probability of performance degradation or failure caused by high temperature, and extend the service life of the keyboard.

[0007] More preferably, the bottom of the keyboard base is fixedly connected to two anti-slip pads, which are symmetrically distributed on the bottom of the keyboard base.

[0008] More preferably, the bottom of the keyboard base is fixedly connected to two fixing plates, which are symmetrically distributed at the bottom of the keyboard base.

[0009] More preferably, the interior of the fixed plate is movably connected to a hinge shaft via a hinge, and a support block is fixedly connected to the side surface of the hinge shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, the PCB back film is a thermally conductive silicone pad. The thermally conductive silicone pad is a sheet material with high thermal conductivity, made of silicone as the main material and various thermally conductive fillers. It can quickly transfer heat from the heat source to the heat dissipation device or other heat dissipation medium, effectively reducing the temperature of the heat source. It has a soft texture and can fit well with various irregular surfaces, filling the tiny gaps between the heat source and the heat dissipation device, and improving the heat transfer efficiency.

[0012] In this invention, air cooling effectively reduces the internal temperature of the keyboard, preventing heat buildup caused by prolonged use. This helps maintain the stable operation of the magnetic shaft and other electronic components, reduces performance degradation or failure probability caused by high temperatures, and extends the keyboard's lifespan.

Through hole 12: During prolonged use, the magnetic axis inside the magnetic keyboard will generate a high amount of heat. During the heating process, the PCB back film 2 can dissipate the heat inside the keyboard in a timely manner. The PCB back film 2 is a thermally conductive silicone pad. The thermally conductive silicone pad is a sheet material with high thermal conductivity, made of silicone as the main material and various thermally conductive fillers.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when using this air-cooled magnetic axis keyboard, the magnetic axis inside the keyboard will generate a lot of heat during prolonged use. During the heating process, the PCB back film 2 can dissipate the heat inside the keyboard in a timely manner. The PCB back film 2 is a thermally conductive silicone pad, which is a sheet material with high thermal conductivity made of silicone as the main material and various thermally conductive fillers.
