Referring to fig. 1, in the embodiment of the present invention, the touch keyboard includes a base and a touch key cap, the touch key cap is disposed on the base, and the touch key cap includes a touch IC1, a PCB 2, and an elastic connecting member 3; the touch IC1 generates a touch signal in response to a touch operation of a user; the touch IC1 is arranged opposite to the PCB 2, and a mechanical pressing trigger 4 is arranged on one side of the PCB 2 facing the touch IC1, so that when the elastic connecting piece 3 is compressed, the mechanical pressing trigger 4 is triggered to generate a pressing signal; the touch IC1 is elastically connected with the PCB 2 through the elastic connecting piece 3, and the touch IC1 is in communication connection with the PCB 2 so as to transmit the touch signal to the PCB 2.

The touch key cap is a key of the keyboard, and the key cap includes a touch IC1, a PCB 2, and an elastic connector 3. The touch IC1 is located above and closer to the location where the user presses. Specifically, the touch IC1 can generate a corresponding touch signal in response to a touch operation by a user, typically a touch operation.

The PCB 2 is located below the touch IC1, the elastic connector 3 is disposed between the PCB 2 and the touch IC1, and the mechanical pressing trigger 4 is disposed on a side of the PCB 2 facing the touch IC 1. The mechanical pressing trigger 4 can be specifically a dome sheet (dome sheet), a metal patch key, a touch capacitor and other structures which need to be pressed by an entity to generate a corresponding signal, so that when a touch key cap is pressed, the stroke of the elastic connecting piece 3 can be compressed to trigger the mechanical pressing trigger 4, namely, the elastic connecting piece 3 is compressed to trigger the mechanical pressing trigger 4 to generate a pressing signal, and the traditional mechanical pressing structure is realized. In general, the pressing signal may be directly transmitted to the PCB. The elastic connecting member 3 may be a spring or any other elastic member, and as the case may be, the specific structures of the elastic connecting member 3 and the mechanical pressing trigger 4 may refer to the prior art, which is not described herein again.

The mechanical pressing trigger 4 is arranged on the surface of the PCB 2 facing the touch IC1, so that the mechanical pressing trigger 4 can be responded by the PCB 2 in time when triggered; the touch IC1 needs to be in communication with the PCB 2, so that when the touch function of the touch IC1 is triggered or responded, the touch signal can be timely transmitted to the PCB 2. As for the specific structure of the touch IC1, reference may be made to the prior art, as long as the touch operation of the corresponding user can generate a corresponding touch signal. Specifically, in the embodiment of the present invention, an FPC5 (flexible circuit board) may be disposed between the touch IC1 and the PCB 2 for communication connection. The touch IC1 is electrically connected to the PCB 2 through the FPC5, so that an electrical signal can be timely transmitted when the touch IC1 responds to a touch operation, thereby enabling the touch keyboard to timely respond to the touch operation of a user.

In the embodiment of the present invention, the PCB 2 can specifically acquire two signals, one is a touch signal generated by the touch IC1, and the generation of the touch signal can be generated without the user compressing the elastic connecting member 3; the other signal is a pressing signal generated when the mechanical pressing trigger 4 is triggered, and the generation of the pressing signal requires a user to press the touch key cap, so as to compress the stroke of the elastic connecting piece 3, and finally trigger the mechanical pressing trigger 4 arranged on the surface of the PCB 2.

Of course, the pressing signal generated by the mechanical pressing trigger 4 can be ignored in the software and/or hardware control manner, so that the touch keyboard is only in the touch input mode at this time, and can be set according to the actual situation.

Of course, in addition to the above method, since in the embodiment of the present invention, when the pressing signal is generated, the user must first touch the key cap, so that the touch IC1 generates the corresponding touch signal. Therefore, when the PCB 2 simultaneously or approximately simultaneously acquires the pressing signal and the touch signal corresponding to the same touch key cap, the pressing signal is only processed by ignoring the touch signal, so as to execute the key operation of the user; when the user only performs touch operation on the touch key cap, does not press the elastic connecting piece 3, or presses the elastic connecting piece 3 and does not trigger the mechanical pressing trigger piece 4, since only the touch signal is generated at this time, only the touch operation of the user can be executed at this time.

In addition to the above, the touch keyboard may be switched between the conventional mechanical input mode and the touch input mode by other methods or combinations of the above, which is not described herein again.
