Description

Technical Field

[0001] The utility model relates to the technical field of keyboards, in particular to an ice-feeling keyboard armrest. Background Art

[0002] The keyboard pad, also known as the keyboard armrest, is mainly used to support and cradle our wrists. The unique feature of this pad is that it is equipped with soft foam inside, which not only makes the pad very soft, but also makes our wrists feel very comfortable when placed on it without worrying about wear and tear. In addition, the design of the keyboard pad also cleverly raises the wrist to a height close to that of the keyboard, so that when typing, our palms do not need to tilt upwards effortlessly, which greatly reduces the fatigue when using the keyboard for a long time.

[0003] Although the softness of the foam brings an extremely comfortable experience to users, the PU leather or cloth originally wrapped outside the foam has an obvious problem: long-term use will make the hands feel stuffy and easy to sweat. Even if ice cloth is used on the market to replace traditional PU leather or cloth to give users a cool feeling, after long-term use, there will still be heat accumulation, hot and sweaty palms, and the experience is not good. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an ice-feeling keyboard armrest which has a self-cooling function and can maintain a cool feeling for a long time.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: an ice-sensing keyboard armrest, comprising a bottom shell and a mounting frame connected to the bottom shell, a heat-conducting plate is installed on the upper surface of the mounting frame, and the characteristics are: the mounting frame is fixedly equipped with a semiconductor refrigeration sheet thermally bonded to the lower side of the heat-conducting plate, a control board electrically connected to the semiconductor refrigeration sheet and a heat dissipation device thermally bonded to the other side of the semiconductor refrigeration sheet, the bottom shell or the mounting frame is equipped with a socket for connecting a power supply, and the socket is electrically connected to the control board.

[0006] Preferably, the heat dissipation device includes a heat dissipation fin thermally bonded to the other side of the semiconductor refrigeration plate and a centrifugal fan installed at the end of the heat dissipation fin, the bottom surface of the bottom shell is provided with an air inlet corresponding to the air inlet position of the centrifugal fan, and the side of the base is provided with an air outlet for discharging hot air.

[0007] Preferably, the heat dissipation device further comprises an air duct, two ends of which are respectively sealedly connected to the air outlet and the air outlet of the centrifugal fan.

[0008] Preferably, a wind shield is provided at the outer end of the heat dissipation fin.

[0009] Preferably, the heat conducting plate is made of heat conducting silica gel or heat conducting silicone rubber material.

[0010] Preferably, the outer surface of the heat conducting plate is covered with a wear-resistant layer, and the wear-resistant layer is made of elastic cloth or imitation leather material.

[0011] The beneficial effects of the utility model are as follows: the utility model provides an ice-feeling keyboard armrest. In actual application, the keyboard armrest is arranged in front and behind the keyboard. When typing normally, the wrist is just located on the keyboard armrest. The control panel is electrically connected to the external power supply device through the socket. After the semiconductor refrigeration plate is powered on, the temperature of the side in contact with the heat conduction plate is reduced. After the heat of the heat conduction plate is absorbed by the semiconductor refrigeration plate, it can be maintained at a constant temperature below 15 degrees Celsius. During use, it effectively absorbs the heat of the user's hands, bringing a cool and comfortable feeling to the hands. Even if used for a long time, the temperature of the heat conduction plate is still maintained at a low temperature, and the comfort is significantly improved. It is highly practical. Due to the design of the heat dissipation device, the heat generated on the other side of the semiconductor refrigeration plate can be dissipated outside the keyboard armrest, solving the heat dissipation problem of the semiconductor refrigeration plate, avoiding damage due to heat accumulation, and having the advantages of high reliability and long service life.

[0015] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0016] like Figures 1 to 3 As shown, an ice-feeling keyboard armrest comprises a bottom shell 1 and a mounting frame 2 matched with the bottom shell 1, a heat-conducting plate 3 is installed on the upper surface of the mounting frame 2, and it is characterized in that: the mounting frame 2 is fixedly equipped with a semiconductor refrigeration sheet 4 heat-conductingly bonded to the lower side of the heat-conducting plate 3, a control board electrically connected to the semiconductor refrigeration sheet 4 and a heat dissipation device heat-conductingly bonded to the other side of the semiconductor refrigeration sheet 4, the bottom shell 1 or the mounting frame 2 is equipped with a socket for connecting a power supply, and the socket is electrically connected to the control board.

[0017] In actual application, the keyboard armrest is arranged in front of the keyboard. The wrist is just on the keyboard armrest during normal typing. The control board is electrically connected to the external power supply device through the socket. After the semiconductor refrigeration sheet 4 is energized, the temperature of the side in contact with the heat conduction plate 3 decreases. The heat of the heat conduction plate 3 is absorbed by the semiconductor refrigeration sheet 4 and can be maintained at a constant temperature below 15 degrees Celsius. During use, it effectively absorbs the heat of the user's hands and brings a cool and comfortable feeling to the hands. Even if used for a long time, the temperature of the heat conduction plate 3 is still maintained at a relatively low temperature, the comfort is significantly improved, and the practicality is strong.

[0018] Due to the design of the heat dissipation device, the heat generated on the other side of the semiconductor cooling plate 4 can be dissipated outside the keyboard armrest, solving the heat dissipation problem of the semiconductor cooling plate 4 and avoiding damage due to heat accumulation. It has the advantages of high reliability and long service life.

[0019] In this embodiment, the heat dissipation device includes a heat dissipation fin 5 which is thermally bonded to the other side of the semiconductor cooling sheet 4 and a centrifugal fan 6 installed at the end of the heat dissipation fin 5. The bottom surface of the bottom shell 1 is provided with an air inlet 7 corresponding to the air inlet position of the centrifugal fan 6, and the side of the base is provided with an air outlet 8 for discharging hot air. Specifically, the heat dissipation device also includes an air duct 9, and the two ends of the air duct 9 are respectively sealed and connected to the air outlet 8 and the air outlet of the centrifugal fan 6. During use, the heat dissipation device inhales cold air from the air inlet 7, exchanges heat with the heat dissipation fin 5, and then passes through the air duct 9 from the air outlet 8, with high heat conversion efficiency and obvious heat dissipation effect.

[0020] In this embodiment, a wind shield 10 is installed at the outer end of the heat dissipation fin 5. The design of the wind shield 10 can limit the cold air coming out of the centrifugal fan 6 to the gap between adjacent heat dissipation fins 5, ensuring more sufficient heat exchange between the cold air and the heat dissipation fins 5, thereby further improving the heat dissipation efficiency.

[0021] In this embodiment, the heat conducting plate 3 is made of heat conducting silica gel or heat conducting silicone rubber material. On the premise of evenly distributing the cooling capacity of the semiconductor refrigeration plate 4 to the entire heat conducting plate 3, the comfort of the keyboard armrest is improved, and the user experience is better.

[0022] In this embodiment, the outer surface of the heat conducting plate 3 is covered with a wear-resistant layer 11, and the wear-resistant layer 11 is made of elastic cloth or imitation leather material. Under the premise of ensuring comfort, it has stronger wear resistance and longer service life.
