Therefore, the external equipment sharing device disclosed by the invention is provided with at least one external equipment interface and at least two host interfaces, and the external equipment can be mutually and switchably connected to different hosts through the external equipment interface and the control module, so that the switching sharing of the same external equipment is realized between the at least two hosts.

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an external device sharing apparatus provided in an embodiment of the present disclosure.

In one aspect, as shown in fig. 1, the present embodiment provides an external device sharing apparatus 100, the external device sharing apparatus 100 including: a control module 1, at least one external device interface 2 and at least two host interfaces 23; at least one external device interface 2 is connected with at least two host interfaces 23 through the control module 1; the control module 1 is configured to control that at least one external device interface 2 is capable of switching between being connected to at least two host interfaces 23, respectively.

The external device sharing apparatus 100 of the present disclosure has at least one external device interface 2 and at least two host interfaces 23, and external devices can be connected to different hosts 400 through the external device interface 2 and the control module 1 in a mutually switchable manner, so that switching sharing of the same external device is achieved between the at least two hosts 400.

Illustratively, the external device interface 2 may be one or more, for example, one, two, three, four external device interfaces 2. When the external device interface 2 is plural, the external device interface 2 may include an input device interface 21 and an output device interface 22. The host interfaces 23 may be two or more, for example, two, three, four host interfaces 23.

In some possible implementations, the at least one external device interface 2 includes, but is not limited to: USB interface, type-C interface, lighting interface, HDMI interface, VGA interface, DVI interface, DP interface, etc.; the at least two host interfaces 23 include, but are not limited to: USB interface, type-C interface, lighting interface, HDMI interface, VGA interface, DVI interface, DP interface, etc.

In other possible implementations, the at least one external device interface 2 may also be connected to the external device by a wireless connection, for example, bluetooth (blue) technology, wi-Fi technology, infrared Communication (IrDA) technology, near Field Communication (NFC) technology, zigBee (ZigBee) technology, ultra Wideband (UWB) technology, dual-interface SIM card (SIMpass) technology, and smart phone card (RF-SIM) technology.

In some possible implementations, at least one external device interface 2 is used to connect input devices such as a mouse, keyboard, tablet, digitizer, scanner, etc., and/or output devices such as a display, printer, facsimile, etc.

Illustratively, the host 400 connected to at least two host interfaces 23 is a computer host (refer to fig. 10), and a container for placing a motherboard and other main components in a computer hardware system.

Fig. 2 is a schematic structural diagram of an external device sharing apparatus according to another embodiment of the present disclosure.

As shown in connection with fig. 2, in some embodiments, at least one external device interface 2 comprises: at least one input device interface 21; the control module 1 includes: an input control unit 110; the input control unit 110 includes a first switch 111, and the first switch 111 includes at least one first connection 1111 and at least two second connections 1112; at least one first connection end 1111 is electrically connected to at least one input device interface 21, and at least two second connection ends 1112 are electrically connected to at least two host interfaces 23, respectively; the input control unit 110 includes at least a first state and a second state that can be switched to each other; in the first state and the second state, at least one first connection end 1111 is electrically connected to a different second connection end 1112; the input control unit 110 is configured to be able to perform switching of the first state and the second state in response to an input switching instruction.

The external device sharing apparatus 100 of the present embodiment is designed with at least one input device interface 21, and can support connection of at least one input device 300 (refer to fig. 10), and the input device 300 is a mouse or a keyboard, for example. The single input device 300 is alternately connected to at least two host interfaces 23 by switching of the first switching switch 111, thereby being connected to the host 400 connected to the host interfaces 23. When the first connection 1111 is connected to one of the second connection 1112, the input device 300 is directly connected to the host 400, and the input operation can be performed to the host 400 through the input device 300.

In some possible implementations, when the number of input device interfaces 21 is one, the first switch 111 includes one first connection 1111 and two second connections 1112, and the first switch 111 may be a single pole double throw switch, which has one movable end and two stationary ends, where the first connection 1111 is the movable end, and the two second connections 1112 are the two stationary ends.

It can be understood that when the number of the input device interfaces 21 is two or more, the number of the first connection terminals 1111 is correspondingly increased to be two or more, that is, the number of the first connection terminals 1111 is consistent with the number of the input device interfaces 21, and the first connection terminals 1111 and the input device interfaces are electrically connected in a one-to-one correspondence. For example, the number of the input device interfaces 21 and the first connection terminals 1111 is two, and the first switching switch 111 is a double pole double throw switch.

Correspondingly, the number of the host interfaces 23 is identical to the number of the second connection ends 1112, and the host interfaces are electrically connected in a one-to-one correspondence. For example, the number of the input device interfaces 21 and the first connection terminals 1111 is one, the number of the host interfaces 23 and the second connection terminals 1112 is three, and the first changeover switch 111 is a single pole three throw switch. The number of the input device interfaces 21 and the first connection terminals 1111 is two, the number of the host interfaces 23 and the second connection terminals 1112 is three, and the first switch 111 is a double pole triple throw switch.

In some possible implementations, the input control unit 110 uses an integral control strategy or a separate control strategy for on-off control of two or more input device interfaces 21. The integrated control strategy is to synchronously switch a plurality of first connection ends 1111 corresponding to the plurality of input device interfaces 21 to a second connection end 1112; the respective control policies are to control and switch the respective first connection terminals 1111 corresponding to the input device interfaces 21 to different second connection terminals 1112. Illustratively, the plurality of first connection terminals 1111 are respectively connected to different second connection terminals 1112 at the same time, that is, the plurality of input devices 300 simultaneously correspond to the plurality of hosts 400, and operate on the plurality of hosts 400. For example, the first host 400 is connected to the mouse through the cooperation of a set of the first connection end 1111 and the second connection end 1112, so that the mouse can control the first host 400 to work; the second host 400 is connected to the keyboard through the cooperation of the first connection 1111 and the second connection 1112, so that the keyboard can control the first host 400 to operate.

As shown in conjunction with fig. 2, in some embodiments, the external device sharing apparatus 100 further includes: a first switching key 4; the input switching instruction includes: a first instruction; the first switching key 4 is configured to issue a first instruction to the input control unit 110 when the first switching key 4 is triggered.

The external device sharing apparatus 100 of the present embodiment can send a first instruction to the input control unit 110 by triggering the first switching key 4, where the input control unit 110 switches the state of the input control unit 110 under the command of the first instruction, for example, the first state switches to the second state, or the second state switches back to the first state. For example, referring to fig. 1, in a default state, the right host interface 23 of the two host interfaces 23 is electrically connected to the input device interface 21 through the connection between the first connection end 1111 and the second connection end 1112, and after the input control unit 110 receives the first instruction, the first connection end 1111 is switched to the other second connection end 1112, so that the left host interface 23 is electrically connected to the input device interface 21.

In some possible implementations, the first switching key 4 is located on the body of the external device sharing apparatus 100. For example, the first switching key 4 is a physical button facing outward on the housing 11 of the external device sharing apparatus 100, and the user can be triggered by pressing a finger.

In other possible implementations, the first switching key 4 is at least one of an operability control, a gesture recognition control, and an image recognition control. The operability controls include at least one of a button control, a scroll bar control, an icon control, and a menu control.

In other possible implementations, the first switching key 4 is located outside the external device sharing apparatus 100 and is communicatively connected to the input control unit 110 inside thereof by wired or wireless means. Or the first switching key 4 is integrated on the input device 300 connected to the input device interface 21. Further, the key value of the first switching key 4 is given to the original key, button or any combination of key and button on the input device 300.

In some possible implementations, the first instruction includes, but is not limited to: mechanical force, electrical signals, pressure signals, binary numbers, and the like.

As shown in conjunction with fig. 2 and 10, in some embodiments, the external device sharing apparatus 100 further includes: a first detection unit 5; the input switching instruction includes: a second instruction; the first detection unit 5 is configured to detect an operation state of the input device 300 connected to the at least one input device interface 21 and to issue a second instruction to the input control unit 110 when the input device 300 reaches the first target state.

The external device sharing apparatus 100 of the present embodiment detects, in real time, the operation state of the input device 300 connected to the external device sharing apparatus 100 through the first detection unit 5, and when the input device 300 reaches the first target state, issues a second instruction to the input control unit 110, and the input control unit 110 switches the state of the input control unit 110 under the command of the second instruction, for example, the first state switches to the second state, or the second state switches back to the first state.

The first detection unit 5 is illustratively a sensing element or application. When the first detection unit 5 is a sensing component, the first detection unit 5 is disposed in the input device 300 or the external device sharing apparatus 100; when the first detection unit 5 is an application program, the first detection unit 5 is stored and run in the host 400, for example, when the input device 300 is a mouse, the first detection unit 5 may be a program that is stored and run separately, or may be embedded in a driver of the mouse, and stored and run together with the driver.

In some embodiments, the operating state of the input device 300 includes: coordinate state, movement state, trajectory state, input state.

Illustratively, the input device 300 is a mouse and the operating state of the input device 300 includes a coordinate state.

When the first detection unit 5 detects that the coordinate state of the mouse reaches the first target state, the first detection unit 5 issues a second instruction to the input control unit 110, and the input control unit 110 switches the state of the input control unit 110 under the second instruction.

For example, if the first target state is a state in which the coordinate state of the mouse has reached the boundary of the current display area in the first direction and also has an increasing state in the first direction, the first detection unit 5 issues a second instruction to the input control unit 110. If the display area of the other host computer 400 also exists in the first direction of the boundary of the display area, the second instruction is to control the input control unit 110 to switch the input device 300 to be connected with the other host computer 400, so that the mouse can complete the automatic switching between the two host computers 400, and the two host computers 400 can automatically share one mouse according to the coordinate state of the mouse.

As shown in conjunction with fig. 2 and 10, in some embodiments, the external device sharing apparatus 100 further includes: a second detection unit 6; the input switching instruction includes: a third instruction; the second detection unit 6 is configured to detect an operation state of the host 400 connected to the at least two host interfaces 23 and issue a third instruction to the input control unit 110 when the host 400 reaches the second target state.

The external device sharing apparatus 100 of the present embodiment is further provided with a second detection unit 6, where the second detection unit 6 is configured to detect an operation state of the host 400 connected to the host interface 23, and send a control instruction to the input control unit 110 according to the operation state of the host 400, so as to implement switching sharing of the input device 300.

The second detection unit 6 is, for example, a sensor element or an application. When the second detection unit 6 is a sensing component, the second detection unit 6 is disposed in the host 400 or the external device sharing apparatus 100; when the second detection unit 6 is an application program, the second detection unit 6 is stored and run in the host 400, for example, when the input device 300 is a keyboard, the second detection unit 6 may be a program that is stored and run separately, or may be embedded in a driver of the keyboard, and stored and run together with the driver.

In some embodiments, the operational state of host 400 includes: a startup state, a shutdown state, a dormant state, a screen off state and an awake state. Thus, when only one of the two or more hosts 400 connected to the external device sharing apparatus 100 is powered on, the second detecting unit 6 issues an instruction, and the input control unit 110 controls the input device 300 to be connected to the host 400 in the powered on state. When one host 400 of two or more hosts 400 is powered off, the second detection unit 6 sends out an instruction, and the input control unit 110 controls the input device 300 to switch to the other host 400 which is not powered off. When two or more hosts 400 are in sleep or off screen, the hosts 400 perform the same operation as when they are powered off. When the host 400 in the sleep or off-screen state is awakened, the second detection unit 6 may issue an instruction, and the input control unit 110 controls the input device 300 to switch back to the awakened host 400.

In some embodiments, the input device interfaces 21 are at least two, and the at least two input device interfaces 21 are respectively used for connecting a mouse and a keyboard. The mouse and the keyboard are two kinds of input devices 300 commonly used for the computer device 500, and the external device sharing apparatus 100 of this embodiment can support sharing of the mouse and the keyboard at the same time, so as to facilitate use of the computer device.

The external device sharing apparatus 100 of the present embodiment includes at least one output device interface 22 and an output control unit 120, where the output control unit 120 implements that at least two host interfaces 23 are simultaneously connected to the same output device through a second switch 121, or that at least two host interfaces 23 are respectively connected to different output devices.
