In one embodiment, the panel layer is formed with a convex hull corresponding to the plurality of keys, and the air bag is located below the convex hull. When a user presses a key, the bottom of the key is contacted with the convex hull, so that the contact hand feeling at the moment of pressing is provided by the convex hull, the convex hull is pressed down to be contacted with the air bag along with the contact, and the subsequent hand feeling is provided by the air bag and is related to the air pressure in the air bag; in addition, it can be appreciated that there are two hand feel of pressing a key, similar to the paragraph hand feel in real life, which will provide a richer experience for the operator. The panel layer, the circuit layer and the bottom lining are made of flexible materials, and the shunt air plate is made of hard materials. Wherein, flexible panel layer, circuit layer and substrate form the protection to gasbag and branching gas board, improve the life of gasbag and branching gas board, also easier silk screen printing circuit on the circuit layer for better be connected with control valve and pressure sensor.
In one embodiment, as shown in fig. 2, the branching air plates have a plurality, and among the plurality of air bags, the air bags located in the same row are connected to the same branching air plate. A plurality of output ports are arranged in one ventilation cavity channel of each branching air plate, and control valves are arranged in the plurality of output ports. Therefore, in the traditional 64-key keyboard, only the branch air plates corresponding to each row of keys are required to be arranged, each branch air plate is connected with one air pump, the ventilation cavity channels in the branch air plates can be arranged straight, and the processing is convenient, for example, the ventilation cavity channels can be directly drilled in the hard branch air plates, and then the output ports are drilled along one side of the ventilation cavity channels, so that the processing process can be simplified.
In an embodiment, as shown in fig. 4-5, the control valve includes a micro tunnel, a blocking portion and a mounting groove formed in the micro tunnel are disposed in the micro tunnel, an electrode substrate is disposed in the mounting groove, and a flexible membrane is formed on the mounting groove, and in a normal state, the flexible membrane is tightly attached under the blocking portion so that the micro tunnel is closed, and when the electrode substrate is electrified, the flexible membrane is attracted by the electrode substrate and is far away from the blocking portion so that the micro tunnel is unobstructed.

in step S1, an intelligent model corresponding to the current controller or account number and located at the cloud end is read, and the air pump and the control valve are driven according to the set value of the model for each pressure sensor, so that the value of the pressure sensor tends to the set value in a normal state.
Because the pressing force of each key is different for each user, the pressure in each air bag should be inconsistent. The intelligent model can be bound with a software account number or a serial number of a controller, when the keyboard is connected with a computer, a user logs in corresponding management software, or the management software reads the serial number of the controller, so that the trained model can be called, and the user can still enjoy the hand feeling of the keyboard bound with a person after replacing the keyboard or the computer.
The intelligent model can be any neural network model, deep learning model and the like, and can enable the pressure of the air bag to reach an ideal value according to a preset input habit or by recording the long-term use habit of a user. The ideal value may be a value that maximizes the input speed of the user.
In step S2, according to the intelligent model, a first threshold value corresponding to each pressure sensor is given, the first threshold value is a floating variable value, and when the value of the pressure sensor reaches the first threshold value, the key corresponding to the pressure sensor is responded.
Wherein the first threshold is a floating variable value, which can be understood as: when a user clicks a conventional word or pinyin, and when the first or second letter of the word or pinyin is pressed, the intelligent model can timely reduce the first threshold value of the predicted next key in combination with the previous and frequent use frequency, so that the user can finish the clicking of the word or pinyin by touching the next key, and the typing speed can be greatly increased. However, when the use scene is a game, the hand feeling should be kept unchanged, and the intelligent model can be judged according to the frequency of triggering the common key of the game, such as a W, A, S, D key commonly used in three-dimensional games.
In one embodiment, the smart model is derived from the following training method: acquiring time sequence data of a pressure sensor, wherein the time sequence data is recorded by keyboard pressing taking time as a shaft; preprocessing the time series data, wherein the preprocessing comprises data cleaning, feature extraction and standardization; training the preprocessed time series data based on the loss function and the optimization algorithm to obtain an intelligent model.
