The one-button switching design of the external control unit significantly improves operational efficiency, while the Type-C interface integrates power supply and data transmission, reducing external power supplies and cable tangles, making multi-device switching faster and desktop layouts cleaner.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please see Figures 1-5This application provides a switcher 100 capable of switching between multiple devices, comprising: a main body 10, a circuit board 20, a device input interface 11, switching buttons 32, a Type-C interface 13, and a control unit 30. The circuit board 20 is located within the main body 10. The device input interface 11, switching buttons 32, and Type-C interface 13 are electrically connected to the circuit board 20 and are physically connected to the main body 10. The control unit 30 is externally connected to the main body 10. The control unit 30 includes a Type-C connector 31 that plugs into the Type-C interface 13 and at least three switching buttons 32. The control unit 30 has a built-in switching program. At least three devices are electrically connected to the device input interface 11, and the multiple switching buttons 32 are connected one-to-one to the multiple devices through the Type-C interface 13, enabling one-to-one device switching. Pressing a switching button 32 activates the switching program, switching to the device connected to the corresponding switching button 32.

[0040] Specifically, the body 10 is the main structural housing of the switcher, made of engineering plastic or aluminum alloy, and formed by injection molding or CNC machining.

[0041] The main body 10 serves as the core structure of the entire device, with internal mounting positions for securing core electronic components such as the circuit board 20 and battery modules. The circuit board 20 is the functional core of the switcher, undertaking multiple tasks including signal distribution, data processing, and power management. Unified management and control of all interfaces are achieved through PCB routing.

[0042] This application includes at least three device input interfaces 11, including but not limited to: a first HDMI input interface 111, a second HDMI input interface 112, and a USB input interface 113.

[0043] Each interface is electrically connected to the circuit board 20 for connecting to different types of electronic devices, such as laptops, desktops, all-in-ones with video output capabilities, or tablets and smartphones connected via USB interfaces.

[0044] The main body 10 is equipped with a Type-C interface, which can be used for data communication between the control unit 30 and the switch, and also for power supply. The external control unit 30 is connected to the main body 10 via a Type-C connector, ensuring a high-bandwidth and high-stability connection. The control unit 30 is a portable external unit, and its structure can be a small board or a wired control box, allowing users to operate it quickly on a desktop.

[0045] The control unit 30 is equipped with at least three switching buttons 32, each corresponding to an input interface. A switching program is integrated within the control unit 30, which can recognize button signals and transmit them to the circuit board 20 via a Type-C interface, driving the circuit board 20 to switch devices.

[0046] Each switch button 32 allows for one-to-one device switching. Pressing the first button switches to the device connected to the first HDMI input port 111. Pressing the second button switches to the device connected to the second HDMI input port 112. Pressing the third button switches to the device connected to the USB input port 113.

[0047] The switching program can be simple firmware or embedded control logic. It detects the button status through GPIO and sends command signals to circuit board 20. Circuit board 20 controls the selection of signal channels to realize one-way switching of video / data streams to the target device.

[0048] During user operation, the specific operating procedure is as follows: Connect three target devices, such as a mobile phone, tablet, and laptop, to the three input ports of the switcher, such as two HDMI ports and one USB port. The user inserts the control unit 30 into the Type-C port on the switcher body 10. The device automatically detects and establishes data communication. The Type-C port simultaneously powers the control unit 30, activating the switching program inside the control unit 30. The user presses any of the switching buttons 32 on the control unit 30. The switching program recognizes the button input and transmits the corresponding switching command to the circuit board 20 via the Type-C port. The circuit board 20 disconnects the channel of the currently connected device and opens the channel of the target device; if it is an HDMI device, it will also simultaneously switch the output display to the monitor. If it is a USB device, such as a mobile phone, it can switch to the control interface or data synchronization state.

[0049] This switcher can be widely used to allow users to quickly switch between laptops, desktops, and mobile phones using the same set of monitors, keyboards, and mice, improving multitasking efficiency. Alternatively, developers can quickly deploy and debug code on different devices without repeated plugging and unplugging. Furthermore, when a TV or monitor is connected to the switcher, users can switch between home servers, set-top boxes, and game consoles with a single click.

[0050] In one specific embodiment, the circuit board 20 has a built-in battery module, the Type-C interface 13 is connected to the Type-C connector of any of the matching devices, and the battery module is turned on to provide power.

[0051] Specifically, a battery module is built into the circuit board 20, and the Type-C interface is designed as a bidirectional power supply and data transmission interface to achieve portable and multi-purpose power support, which is particularly suitable for the usage needs of modern thin and light devices (such as mobile phones, tablets, and laptops) that are increasingly replacing traditional PCs.

[0052] The battery module is an independent power supply unit mounted on circuit board 20. It can be a rechargeable lithium polymer battery or a lithium-ion battery module, with a rated output voltage such as 5V / 9V / 12V, selected based on the device's power consumption. The battery module is connected to circuit board 20 via a power management chip (PMIC) to provide power to circuit board 20, enabling the switch to operate normally even without an external power supply. It provides reverse power to the connected device when the external Type-C port is not powered. The battery module can be charged via the Type-C interface.

[0053] In this embodiment, the Type-C interface is used not only to connect to the external control unit 30, but also to connect to any compatible device such as a mobile phone / laptop. The Type-C interface supports the USB PD protocol and can identify the host / device role of the connected device. When an external device is detected, if the device is rechargeable, the battery module supplies power to the device through the Type-C port. If the control unit 30 is connected, the system switches to data communication mode, with power supply and data transmission occurring simultaneously. The system uses an internal detection module for port identification and power switching control.

[0054] In one specific embodiment, when there are three input interfaces, three devices are connected respectively. Specifically, the three input interfaces are a first HDMI input interface 111, a second HDMI input interface 112, and a USB input interface 113. The first HDMI input interface 111 and the second HDMI input interface 112 are electrically connected to the devices having displays.

[0055] Specifically, all interfaces are directly electrically connected to the circuit board 20, and the connected devices transmit signals to the body 10 through different communication protocols. Signal processing and channel allocation are performed through switching logic.

[0056] The devices connected to the first HDMI input interface 111 and the second HDMI input interface 112 are devices with display components, i.e. devices with their own screen display capabilities. The switch synchronizes its display output to the output end of the main body 10, such as the HDMIOUT port, through signal selection logic, so that the external display can mirror or expand the corresponding device screen.

[0057] Devices connected via USB can output to the same display via USB Display protocols such as USB-C Alt Mode or DisplayLink, or simply interact with data such as via keyboard and mouse control or synchronous operation.

[0058] In one specific embodiment, the control unit 30 has a number of switching buttons 32 that are the same as the number of input interfaces.

[0059] Specifically, each switch button 32 corresponds to an input interface, achieving a "one-to-one" physical mapping.

[0060] In one specific embodiment, the control unit 30 includes a first switching button 321, a second switching button 322, and a third switching button 323 that can be activated simultaneously. The first switching button 321 is connected to a device with a display through the first HDMI input interface 111. The second switching button 322 is connected to another device with a display through the second HDMI input interface 112. The third switching button 323 is connected to the device through the USB input interface 113.

[0061] Specifically, the control unit 30 is designed as a compact and portable wired control box structure, allowing users to operate it quickly on their desktop. The surface of the control unit 30 has three switching buttons 32: a first switching button 321, a second switching button 322, and a third switching button 323. These three buttons are arranged horizontally in a straight line on the top front of the control unit 30.

[0062] The first switching button 321 is connected internally to the first HDMI input interface on the main body 10. In practical applications, the first HDMI input interface can be connected to a desktop computer with a display. When the user connects the desktop computer to the first HDMI input interface via an HDMI cable and presses the first switching button 321, the switching program inside the control unit 30 immediately recognizes the button input and transmits the switching command to the circuit board 20 inside the main body 10 via the Type-C interface. After receiving the command, the circuit board 20 quickly switches the signal channel to the first HDMI input interface. At this time, the external monitor connected to the switcher output interface 14 will display the desktop computer's screen, and the user can then use the same keyboard and mouse to operate the desktop computer. The second switching button 322 operates on the same principle as the second HDMI input interface, and the second switching button 322 operates on the same principle as the USB input interface 113.

[0063] The three switching buttons 32 also have the function of simultaneous activation. In terms of hardware design, the internal circuitry of the control unit 30 adopts a parallel connection method, with each switching button 32 connected to the microprocessor through an independent signal line. The microprocessor can receive input signals from multiple buttons simultaneously and process them according to preset program logic. When the user presses the first switching button 321, the second switching button 322, and the third switching button 323 simultaneously, the microprocessor will detect that the signals of these three buttons are triggered simultaneously. At this time, the microprocessor will send a special switching command to the circuit board 20, which will instruct the circuit board 20 to keep the signal channels of all connected devices in the open state.

[0064] In one specific embodiment, the switcher has an output interface 14. The output interface 14 includes a first HDMI output interface 141 and a second HDMI output interface 142.

[0065] Specifically, the first HDMI output interface 141 and the second HDMI output interface 142 are arranged side by side in the output interface 14 area. Both the first HDMI output interface 141 and the second HDMI output interface 142 are standard HDMI 2.1 interface, and the interface shell is made of high-strength metal material.

[0066] When a user selects to switch to a specific input interface via control unit 30, the signal from the device connected to that input interface is transmitted to the corresponding output interface 14 through the switcher's internal circuitry. For example, when the user presses the switch button 32 on control unit 30 corresponding to the first HDMI input interface, the signal from the device connected to the first HDMI input interface, such as a desktop computer, is processed and distributed by circuit board 20 and transmitted to either the first HDMI output interface 14 or the second HDMI output interface 14. If output to both output interfaces 14 is required simultaneously, the signal distribution chip inside the switcher will copy or split the signal according to preset rules and transmit it to the two output interfaces 14 respectively.

[0067] In one specific embodiment, the switcher further includes a network interface 15, a mouse interface 16, and a keyboard interface 17 located on the body 10 and connected to the circuit board 20.

[0068] Specifically, network interface 15 is a standard RJ45 Gigabit Ethernet interface, conforming to the IEEE 802.3 standard and supporting adaptive transmission rates of 10 / 100 / 1000Mbps. This interface incorporates a high-quality network transformer, effectively isolating external electromagnetic interference and ensuring the stability and reliability of network signal transmission. Simultaneously, the interface features Wake-on-LAN functionality, allowing users to remotely wake up connected devices in sleep mode via the network, enabling intelligent management.

[0069] The mouse interface 16 uses a standard USB Type-A interface, supports the USB 2.0 protocol, and has a maximum transmission rate of 480Mbps. This interface features hot-swapping capability, allowing users to plug and unplug the mouse at any time without turning off the switch or connected devices, providing convenience and speed. The interface employs advanced signal enhancement technology internally, effectively reducing signal attenuation and interference to ensure accurate and smooth mouse operation.

[0070] Keyboard interface 17 is also a standard USB interface, supporting the USB 2.0 protocol and featuring hot-swapping capability. Similar to mouse interface 16, it is compatible with various types of keyboard devices, including mechanical keyboards, membrane keyboards, and wireless keyboards. The interface integrates a smart recognition chip that automatically identifies the key layout and function settings of different keyboards, ensuring the keyboard functions correctly when switched to different devices.

[0071] In one specific embodiment, the switcher further includes a power switch 18 and a toggle button 32 located on the body 10 and connected to the circuit board 20. Pressing the toggle button 32 sequentially switches the devices connected to the input interface.

[0072] Specifically, the power button 18 and the toggle button 12 are connected to the circuit board 20 inside the main body 10 via a flexible printed circuit board 20. The FPC has advantages such as good flexibility, small size, and stable signal transmission, enabling it to adapt to the bending and movement of the button area, ensuring accurate transmission of button signals to the circuit board 20. At the connection between the button and the FPC, a conductive rubber button structure is used. Conductive rubber has good elasticity and conductivity; when the button is pressed, the conductive rubber contacts the contacts on the FPC, forming an electrical signal path and transmitting the button information to the circuit board 20.

[0073] When the user presses the power button 18, the conductive rubber beneath the button contacts the power control contacts on the FPC, generating a switching signal. Upon receiving this signal, the power management chip on circuit board 20 controls the overall power state of the switcher. The first press of the power button 18 activates the switcher's power supply system, providing operating voltage to various components (such as input / output interface 14, signal processing chip, etc.), and the switcher enters the power-on state. Pressing the power button 18 again cuts off the power supply, and the switcher enters the power-off state.

[0074] The switching key 12 is connected to the switching logic control chip on the circuit board 20. Each switching key 12 corresponds to a specific input interface number. When the user presses the switching key 12 in sequence, the switching logic control chip will switch the devices connected to the input interfaces in a preset order. For example, assuming the switcher has three input interfaces labeled as input interface 1, input interface 2, and input interface 3, initially, the switcher defaults to connecting to the device connected to input interface 1. When the user presses the switching key 12 for the first time, the switching logic control chip receives the signal from the switching key 12 and switches the input channel of the signal processing chip to input interface 2. At this time, the signal from the device connected to input interface 2 will be transmitted to output interface 14. When the user presses the switching key 12 for the second time, the switching logic control chip will switch the input channel to input interface 3. When the user presses the switching key 12 for the third time, the switching logic control chip will switch the input channel back to input interface 1.

[0075] In one specific embodiment, the device is a tablet, desktop computer, laptop computer, or mobile phone.

[0076] In one specific embodiment, the switcher further includes a fixing structure 40 located within the body 10, fixedly connected to the body 10, and locked to the circuit board 20.

[0077] Specifically, the fixed structure 40 is integrated into the switch body 10. On the one hand, it can provide physical protection for the internal circuit board 20, avoiding direct contact with external collisions, dust or liquids. On the other hand, through internal space planning, the internal structure of the body 10 is rationally utilized, the signal routing layout is optimized, and the impact of external electromagnetic interference on the circuit board 20 is reduced.

[0078] The fixed structure 40 is rigidly connected to the switch body 10 by mechanical connection methods such as bolts and clips, ensuring that the fixed structure 40 will not loosen or shift due to external forces during equipment handling, installation or use.

[0079] The circuit board 20 is securely fixed to the fixed structure 40 by using screws, elastic clips and other locking methods to prevent the circuit board 20 from shifting or falling off due to vibration, gravity and other factors, while ensuring the stability of the electrical connection between the circuit board 20 and the connector, interface and other components.

[0080] Ensure that circuit board 20 remains stable throughout the switch's operation to prevent signal interruptions, device crashes, or other issues caused by a loose circuit board 20. For example, in video conferencing scenarios, the switch needs to operate stably for extended periods, and a reliable locking connection ensures that the device will not malfunction due to issues with circuit board 20 during the meeting.

[0081] Place the circuit board 20 on the fixed structure 40 and initially position it using positioning pins or slots to ensure alignment between the circuit board 20 and the connection holes of the fixed structure 40. Secure the circuit board 20 to the fixed structure 40 using screws or snap-fit ​​fasteners to ensure a firm connection. Finally, connect the fixed structure 40 to the switch body 10 using bolts or snap-fit ​​fasteners to complete the internal assembly of the switch.

[0082] Therefore, the aforementioned multi-device switching switch 100, by integrating a Type-C interface 13 and multiple input interfaces such as HDMI and USB, directly adapts to modern devices such as mobile phones and tablets, and traditional devices such as desktop computers and laptops, eliminating the need for adapters and reducing usage costs. The one-button switching design of the external control unit 30 significantly improves operational efficiency, while the Type-C interface 13 integrates power supply and data transmission, reducing external power supplies and cable tangles, making multi-device switching faster and desktop layout simpler.

[0083] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
