Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Example one

Referring to fig. 1, an embodiment of the present invention provides a keyboard, including a keyboard housing, a keyboard matrix, a keyboard encoding module, a host interface routing module, and an interface module.

The keyboard matrix, the keyboard coding module, the host interface routing module and the interface module are all positioned in the keyboard shell; wherein,

the input information of the user can be input information generated by the user through knocking different keys on the keyboard shell, such as corresponding codes of letters, numbers, function keys and the like.

The keyboard coding module is connected with the keyboard matrix and used for generating a keyboard scanning code according to the detected input information of the user in cooperation with the keyboard matrix;

the method for generating the keyboard scan code by matching the keyboard coding module with the keyboard matrix is the prior art and is not described herein.

The host interface routing module is connected with the keyboard coding module and used for converting the keyboard scanning code into a code corresponding to the host according to the host selected by a user;

the mode that the user selected the host computer includes a lot of, can select the button through the host computer of knocking and establishing on the shell, realize the endless switching selection in a plurality of joinable host computers, every host computer can correspond to a different host computer pilot lamp, the turning on/off of different host computer pilot lamps represents that the user selects/does not select this host computer.

Here, the type of the host may be, but is not limited to, all hosts that can provide a drive, such as a cellular phone, a PDA, an MID, a PC, and the like. Host-adapted encoding may include, but is not limited to: USB HID keyboard code, PS2 keyboard code, etc.

The host interface routing module can be provided in various chip forms of an electronic circuit, and can also be realized in a software form.

The interface module is connected with the host interface routing module and used for establishing link connection for transmitting codes with the host and sending the codes converted by the host interface routing module to the host selected by a user.

Referring to fig. 2, the working method of the keyboard may specifically include:

step 201: receiving an input signal of a user, and converting input information of the user into a code corresponding to a host according to the host selected by the user;

step 202: and establishing connection with the host selected by the user through the interface module, and sending the code corresponding to the host.

The embodiment of the utility model provides a through increasing host computer interface route module, utilize this module to convert keyboard scanning code into the distinguishable coding form of different host computers for a keyboard can supply a plurality of host computers to use simultaneously, has saved the resource.
