[0002] The keyboard is an indispensable input tool for the computer. For users who need to use the keyboard for a long time, various indicators such as the feel of the keyboard, the rebound force, and the key travel are very important; different users have different requirements for the keyboard, and some people like to press the key Soft and comfortable keyboards, some prefer keyboards with hard and powerful keys; in addition, the same user will use keyboards with different touches at different times, and traditional keyboards cannot provide a variety of touches, and users will not prepare too many touches. There are many types of keyboards around; therefore, the traditional keyboards have the problem of single feel and cannot meet the needs of users

The invention relates to a pressure reducing keyboard comprising a shell, a chip board and keys. Each key comprises a cylinder body. A return spring is arranged in the cylinder body. The upper end of the return spring is connected with a piston rod. The piston rod can reciprocate along the axis of the cylinder body and the piston rod and the cylinder body remain airtight in the process of translation. The upper end of the piston rod is covered with a key cap. A pressure limiting element and a one-way valve are arranged at the bottom of the cylinder body. The pressure limiting element is open when the air pressure in the cylinder body exceeds the threshold value. The one-way valve only allows the air to enter the cylinder body from the outside. The cylinder body is also internally provided with a monitoring element which is matched with the pressure limiting element in a one-to-one way and the monitoring element is electrically connected with the chip board. When the air pressure in the cylinder body abruptly changes, the monitoring element sends a signal to the chip board. The trigger mechanism of the pressure reducing keyboard is unique and a special rebound feel can be provided for the user so as to effectively relieve finger fatigue and have the effect of relaxation and relief.
Description
technical field [0001] The invention relates to a computer accessory, in particular to a keyboard. Background technique [0002] The keyboard is an indispensable input tool for the computer. For users who need to use the keyboard for a long time, various indicators such as the feel of the keyboard, the rebound force, and the key travel are very important; different users have different requirements for the keyboard, and some people like to press the key Soft and comfortable keyboards, some prefer keyboards with hard and powerful keys; in addition, the same user will use keyboards with different touches at different times, and traditional keyboards cannot provide a variety of touches, and users will not prepare too many touches. Therefore, there is a problem that the traditional keyboard has a single feel and cannot meet the needs of users. Contents of the invention [0003] In view of the above problems, the present invention provides a decompression keyboard, which has a...
