And the electronic lock 3 is used for locking the case when in a locking state.
The electronic lock has two states of locking and unlocking, and when the electronic lock is in the locking state, the case can be locked, so that the safety of the host of the electronic equipment is improved.
And the input interface 4 is used for connecting an input device to the mainboard.
The input interface may be a wired interface or a WIreless interface, such as a USB (universal serial Bus) interface, a bluetooth (WIreless-Fidelity) interface, a WI-FI (WIreless Fidelity) interface, or the like, for connecting an input device to the motherboard in a wired or WIreless manner, respectively.
The input device is used for providing input information to the main board, and may be a self-contained input device or an external input device of the electronic device, for example, a self-contained keyboard or an external keyboard of a computer may be specifically used.
And the first interface controller 5 and the second interface controller 6 are arranged on the mainboard and used for carrying out input control on input information from the input interface.
The first interface controller is specifically used for being connected with the input interface when the electronic equipment is in a power-on state, so as to perform input control on input information from the input interface when the electronic equipment is in the power-on state; correspondingly, the second interface controller is specifically configured to be connected with the input interface when the electronic device is in the shutdown state, so as to perform input control on input information from the input interface when the electronic device is in the shutdown state.
For example, when the input interface is a USB interface, the first interface controller may specifically be a USB Host interface control module, as shown in fig. 2, in a conventional manner, the USB Host interface control module is generally disposed in a PCH (solder ball array package) of the electronic device, and when the electronic device such as a computer is in a power-on state, the USB Host in the PCH is connected to an input device such as a keyboard through the USB interface to ensure a normal input function of the electronic device system.
In this application, in order to realize under electronic equipment shutdown state, still can obtain input information from input device such as electronic equipment's keyboard, and then make and to carry out state control to electronic equipment's electronic lock, additionally add second interface controller in electronic equipment, work as when input interface is the USB interface, second interface controller equally can be USBHost interface control module, as shown in FIG. 2, this USB Host that adds specifically can set up in the multi-functional card superIO on the electronic equipment mainboard for when electronic equipment is in shutdown state, provide necessary information access function for electronic lock's state control.
