The keys on the upper part of the second input part 200 and the keys on the upper part of the first input part 100 form all the keys needed or necessary on a keyboard, and then form a complete keyboard. In order to realize the collection of the information of the keys of the second input component 200, a data interface connected with a keyboard circuit is arranged between the first input component 100 and the second input component 200, and the first input component 100 and the second input component 200 are provided with data interfaces. The second input part 200 detects that the key information is transmitted to the first input part 100 through the data interface, and the first input part 100 transmits the key information on the second input part 200 to the computer.
As shown in fig. 1, the second input unit is a regular pattern, that is, the second input unit 200 is a rectangle, and the second input unit 200 may be an irregular image, as shown in fig. 6, a part of the keyboard may be divided into two or more parts as the second input unit 200.
In order to realize the combination of the first input component 100 and the second input component 200, a clamping interface and a combination component are arranged on the butt joint surface of the first input component and the second input component. The clamping interface can be combined in a mode of adopting a plug and a bolt. The combined parts can be adsorbed and combined in a magnetic attraction mode.
The connection can be achieved in several ways.
In one mode
The data interfaces on the first input member 100 and the second input member 200 are connected by data lines. The interface circuit of the key detection circuit of the second input part 200 is integrated to the data line, which is directly electrically connected to the key controller of the first input part 100. In this manner, the second input part 200 is only provided with one mouse controller, which can greatly reduce the cost.

A combined magnet 231 is provided at a position corresponding to the slide hole 111 on the surface of the second input member 200 that abuts against the first input member 100. One side of the middle part of the data connector 120 close to the first input component 100 is provided with a block body made of a magnetic conductive material, and two ends of the data connector 120 are provided with block bodies made of a magnetic conductive material. The change of the position of the data connector 120 is realized by means of adsorption. Wherein, the magnetic property of the combined magnet 231 is greater than that of the hidden magnet 131. The data interface of the second input unit 200 is a set of insertion holes 201 corresponding to the pins 121, which are disposed corresponding to the positions of the placement slots 110.

When the first input member 100 is butted with the second input member 200, the magnetic property of the combined magnet 231 is greater than that of the hidden magnet 131, so that the data connector 120 is attracted to the position of the slide hole 111 close to the second input member 200, and the pin 121 of the data connector protrudes out of the butting surface of the first input member 100 and is plugged into the jack 201 of the second input member 200. Thereby realizing the collection of the key information of the second input part 200 on the key controller of the first input part 100.
