Technical Field

[0001] The utility model relates to the technical field of expansion docks, in particular to an expansion dock capable of controlling the switching of computer screen projection modes. Background Art

[0002] A docking station, also known as a port replicator, is an external device designed specifically for laptop computers. By duplicating or even expanding the ports of a laptop, the laptop can be conveniently connected to multiple accessories or external devices in one stop. The docking station generally has multiple interfaces that can be used to connect more external devices, such as USB flash drives, large-screen monitors, keyboards, mice, scanners and other devices. It can solve the problem of insufficient interfaces on the laptop itself. Using a docking station allows users to enjoy the same convenience and comfort as a desktop computer in the office, and also takes advantage of the convenience of mobile office.

[0003] In the prior art, the expansion dock is only used to expand the computer's interface. When the computer is connected to the projection device, if the user needs to switch the projection mode, it is necessary to perform corresponding operations on the computer and the projection device respectively to complete the switching of the projection mode. The operation is relatively cumbersome and the human-computer interaction is poor. After some projection devices are connected to the computer, the switching of the projection mode can be directly controlled by the computer, but the switching of the projection mode requires corresponding operations in the software. During the projection process, the user repeatedly switches to the software to switch the projection mode, which is also cumbersome, and is not conducive to the user's quick switching of the projection mode.

[0007] Furthermore, the computer includes: a second control module, which is respectively connected to the signal receiving module and the mode switching module, the signal receiving module is used to receive the recognition result sent by the signal transmitting module, the second control module is used to control the mode switching module to perform corresponding screen projection switching operations according to the recognition result received by the signal receiving module, and the mode switching module is used to respond to the third screen projection instruction triggered by the user through the mode switching button and exit the current screen projection mode.

[0008] Furthermore, the mode switching module is used to respond to the first screen projection command triggered by the user through the mode switching button and enter the first screen projection mode, so as to intercept the audio and video data currently played by the computer to obtain the projection data, and send the projection data to the projection device via wired transmission.

[0009] Furthermore, the mode switching module is used to respond to the second screen projection command triggered by the user through the mode switching button and enter the second screen projection mode, so as to intercept the data of the picture currently played by the computer to obtain the projection data, and send the projection data to the projection device via wired transmission.

You only need to input one of the first projection command, the second projection command and the third projection command through the mode switching button to control the computer to switch the projection mode. After the computer switches the projection mode, the corresponding projection data will be automatically sent to the projection device for projection, which simplifies the user's operation of switching the projection mode and brings great convenience to the user.
