Description

Technical Field

[0001] The present application relates to the field of electronic information technology, and in particular to a USB connection mode switching device and a display device. Background Art

[0002] In the prior art, display devices can be connected to some external devices through USB interfaces, such as wireless keyboard and mouse adapters or wireless network cards. However, many current display devices are compatible with different systems and corresponding display channels. For example, display devices that support both Android and Windows systems can switch display channels corresponding to multiple systems at will according to usage needs. During use, some external devices connected through USB interfaces need to adapt to the current system, so they will use USB interfaces that can switch with the display channel to switch the display channel accordingly with the current system switching, such as switching the corresponding display channel through an adapter; other external devices connected through USB interfaces need to be fixedly connected to a certain system, so they need to use USB interfaces with fixed channels so that the connected external devices will not be disconnected from the network when the channel switches. Therefore, it is usually necessary to set at least one USB interface that switches with the channel and at least one USB interface with a fixed display channel on the display device. The USB interface has low flexibility, and users need to choose to connect different USB interfaces according to different usage needs. When switching between different modes of USB interfaces, it is also necessary to unplug the external device from the currently connected USB interface and reinsert it into the corresponding USB interface, which is cumbersome. Utility Model Content

[0003] The embodiments of the present application mainly solve the technical problems that the channel connection mode of the USB interface has low flexibility and the operation of the USB interface for switching different channel connection modes of external devices is cumbersome.

[0004] To solve the above technical problems, a technical solution adopted in the embodiment of the present application is: providing a USB connection mode switching device, applied to a display device, wherein the display device is configured with at least two operating systems, each operating system corresponding to a display channel, the device comprising: a channel switching component, a USB switch, and a USB interface, the input end of the channel switching component being used to connect to a power supply, the output end of the channel switching component being connected to a control pin of the USB switch, and the USB switch being electrically connected to the USB interface; the channel switching component being used to provide a high-level signal or a low-level signal to the USB switch in combination with the power supply, wherein the switching switch component supports manual switching by a user; the USB switch being used to control the USB interface to access a first USB link according to the high-level signal, or to control the USB interface to access a second USB link according to the low-level signal, wherein the display channels corresponding to the first USB link and the second USB link are different.

[0005] The USB connection mode switching device provided in the embodiment of the present application controls the state of the USB switch through the signal output by the channel switching component, and the channel switching component supports manual switching by the user. The USB switch can control the USB interface to access different USB connection links based on the received high-level signal or low-level signal, thereby adapting to the USB connection mode of different display requirements. When the display channel changes, the switching device can conveniently control the USB interface to correspond to different display channels, facilitate the communication connection between the external device and the display device, and improve the flexibility of the connection between the USB interface and the display channel.

[0006] In some embodiments, the channel switching component includes a first pin, a second pin, and an output pin. The first pin is connected to the power supply, the second pin is grounded, and the output pin is connected to the USB switch. By controlling the connection relationship between different pins, the voltage of the output pin is changed to provide a high-level signal or a low-level signal to the USB switch, resulting in a simple structure and low design cost.

[0007] In some embodiments, the channel switching assembly includes a dip switch, the toggle member of which is made of insulating material and disposed on the outer surface of the display device, allowing the user to switch the output voltage of the channel switching assembly between high and low levels. In this embodiment, the dip switch is used as the channel switching assembly. The structural features of the dip switch allow the user to control the channel switching signal provided to the USB switch through the toggle member, resulting in a simple structure and easy operation without any additional learning costs.

[0008] In some embodiments, the first USB link is a switchable USB link. When the USB interface is connected to the switchable USB link, it switches the USB link according to the display channel corresponding to the current operating system. In this embodiment, the switchable USB link is provided so that when the currently used operating system changes, the USB interface can automatically adapt to the display channel corresponding to the current operating system, ensuring the compatibility of the USB interface and allowing connected USB external devices to adapt to the current operating system.

[0009] In some embodiments, the second USB link is a fixed USB link. When the USB interface is connected to the fixed USB link, the current USB link is maintained and does not change with changes in the display channel. In this embodiment, a fixed USB link is provided so that the USB interface is fixedly adapted to a specific USB display channel and does not change with changes in the display channel. For USB external devices that need to be fixed to a system, there is no need to unplug and then replace the USB interface with another fixed link, thereby optimizing the user experience.

[0010] In some embodiments, the USB switch includes a control unit, a USB2.0 switch, and a USB3.0 switch. The control unit is used to control the USB2.0 switch and the USB3.0 switch to be turned on according to the high-level signal, so that the USB interface supports USB2.0 transmission and USB3.0 transmission when connected to the first USB link; the control unit is used to control the USB2.0 switch to be turned on and the USB3.0 switch to be turned off according to the low-level signal, so that the USB interface only supports USB2.0 transmission when connected to the second USB link. In combination with the structure of the USB2.0 switch and the USB3.0 switch, it is possible to provide USB2.0 and USB3.0 link switching with the display channel when receiving a high-level signal, and to enable the USB2.0 link to be mounted separately under a fixed display channel when receiving a low-level signal, without changing with the switching of the display channel, so as to meet the usage requirements of the USB interface in different situations.

[0011] In some embodiments, the USB switch further comprises a USB hub, and the USB 2.0 switch and the USB 3.0 switch are connected to the USB interface via the USB hub. In this embodiment, by providing a USB hub, a single USB interface can be used to connect both the USB 2.0 switch and the USB 3.0 switch, thereby conserving USB interface resources on the device.

[0012] In some embodiments, the power supply is used to provide a 3.3V voltage to the channel switching component. 3.3V power supplies are widely used in computer systems. In this solution, a 3.3V power supply is used to power the channel switching component, which is not only easy to obtain but also controls costs.

[0013] In some embodiments, the apparatus further includes an indicator light disposed on an outer surface of the display device, the indicator light being configured to indicate whether the channel switching component currently corresponds to a high level or a low level. In this solution, the indicator light is used to provide a user with an intuitive prompt, enabling the user to quickly and conveniently determine the USB link currently corresponding to the channel switching component, thereby optimizing the user experience.

[0014] In order to solve the above technical problems, another technical solution adopted in the embodiment of the present application is: providing a display device, wherein the display device includes the USB connection mode switching device as described above.

[0015] Different from the related art, the embodiments of the present application provide a USB connection mode switching device and a display device. The device is applied to a display device, wherein the display device is configured with at least two operating systems, each of which corresponds to a display channel. The device includes: a channel switching component, a USB switch, and a USB interface. The input end of the channel switching component is used to connect to a power supply, and the output end of the channel switching component is connected to a control pin of the USB switch. The USB switch is electrically connected to the USB interface. The channel switching component is used to combine with the power supply to provide a high-level signal or a low-level signal to the USB switch, wherein the switching switch component supports manual switching by the user. The USB switch is used to control the USB interface to access a first USB link according to the high-level signal, or to control the USB interface to access a second USB link according to the low-level signal, wherein the display channels corresponding to the first USB link and the second USB link are different. The device controls the state of the USB switch through the signal output by the channel switching component, and the channel switching component supports manual switching by the user. The USB switch can control the USB interface to access different USB connection links based on the high-level signal or low-level signal received, thereby adapting to USB connection modes with different display requirements. When the display requirements change, the display channel that needs to be adapted also changes. Through this switching device, the USB interface can be easily controlled to adapt to different display channels, facilitating the communication connection between external devices and display devices, and improving the flexibility of the connection between the USB interface and the display channel.

[0018] Figure 3 This is a USB link schematic diagram of the USB connection mode switching device provided in an embodiment of the present application. DETAILED DESCRIPTION

[0019] To facilitate understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "connected" to another element, it may be directly connected to the other element, or one or more intermediate elements may be present therebetween. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0021] For external devices connected to the host via a USB interface, different scenarios may require different channel connection requirements. For example, in some cases, the USB interface needs to switch with the display channel so that the connected external device can adapt to the corresponding system as the display channel switches. For example, when connecting a wireless mouse adapter, if the host's current system switches from Windows to Android, the USB interface needs to switch to the Android system's display channel so that the wireless mouse can adapt to the current Android system. In other cases, the USB interface needs to be fixed to a certain display channel to ensure that the connected external device is not affected by the system switch and is fixed to the display channel of the system. For example, when connecting a wireless network card, if the wireless network card is connected to the Windows system's display channel, and the user switches to Android to process other programs while downloading data in Windows, the USB interface connected to the wireless network card needs to be fixed to the display channel corresponding to the Windows system, and cannot switch to the Android system accordingly. This prevents the channel connected to the wireless network card from being disconnected due to the display channel switch, affecting the original download task.

[0022] In actual usage scenarios, there are at least two usage requirements in the above examples. To this end, the existing solution is to set at least one USB interface that switches with the channel and at least one USB interface with a fixed display channel on the display device to cope with the different usage requirements in the above examples. However, under this method, the user needs to choose to connect to different USB interfaces according to different usage requirements, and when switching between USB interfaces of different modes, it is also necessary to unplug the external device and reinsert it into the corresponding USB interface, which is cumbersome.

[0023] To address the above issues, this application creatively proposes a novel technical solution that implements simple switching of different USB links at the hardware architecture level to improve the flexibility of the USB interface and optimize the user experience. The details are as follows:

[0024] A one-to-many (one-to-two in this application) switching device for changing USB links is provided in the connection circuit of the USB interface. This switching device achieves the effect of changing the USB link corresponding to the USB interface, allowing the USB interface to switch between different USB link types, where different USB link types correspond to different display channels. For example, a USB link may correspond to display channel a of a certain operating system A and be fixed to display channel a, i.e., a fixed USB link. This fixed USB link behaves as follows: if operating system A is switched to another operating system B at a certain moment, and operating system B corresponds to display channel b, the USB link still corresponds to display channel a before the switch. The display channel corresponding to the current USB link will not change due to the operating system switch (which would also change the display channel). For another example, a USB link can follow the display channel corresponding to the current operating system in real time, i.e., a switchable USB link. This switchable USB link behaves as follows: if operating system C (corresponding to display channel c) is used at a certain moment, the USB link corresponds to the current display channel c. Later, at some point, the system switches to operating system D (corresponding to display channel d), and the USB link switches to the current display channel d. Later, at some point, the system switches back to operating system C, and the USB link also switches to the current display channel c. Thus, the switching device can control whether the USB interface is a fixed USB link or a switchable USB link. It should be understood that the fixed USB link and switchable USB link described above are merely examples of two different USB links for ease of explanation.

[0025] Furthermore, in order to achieve the above-mentioned effects, the switching device provided by the present application may include a channel switching component and a USB switch. The output of the channel switching component can be controlled by the user, and by changing its output, the USB switch is controlled to change the USB link of the USB interface, for example, from a fixed USB link to a switchable USB link. The user changes the output of the channel switching component through simple operations, for example, the controller outputs a high-level signal or a low-level signal to the USB switch, so that the USB switch can control the USB interface to access different USB links according to the high-level signal or the low-level signal. In addition, in order to facilitate the actual use of the user, the channel switching component can be a switch-type device. As a daily device that is extremely widely used, most users should understand how to use the switch device. The user changes its output by toggling the switch, which is not only simple to operate but also requires no learning cost. Therefore, the above-mentioned switching device can control the USB link connected to the USB interface according to the user's simple operation, and there is no need to unplug the external device from the currently connected USB interface and reinsert it into another corresponding USB interface.

[0026] Based on the above technical concept, the embodiment of the present application is further elaborated in combination with specific scenarios. The embodiment of the present application provides a USB connection mode switching device, which is applied to a display device, wherein the display device is configured with at least two operating systems, each operating system corresponding to a display channel. Figure 1 The device includes a channel switching component 11, a USB switch 12 and a USB interface 13. The input end of the channel switching component 11 is used to connect to the power supply 20, the output end of the channel switching component 11 is connected to the control pin of the USB switch 12, and the USB switch 12 is electrically connected to the USB interface 13. The channel switching component 11 can provide a high-level signal or a low-level signal to the USB switch 13 in combination with the power supply 20, wherein the channel switching component can be manually switched by the user. The USB switch can control the USB interface to access the first USB link according to the received high-level signal, or control the USB interface to access the second USB link according to the received low-level signal, wherein the display channels corresponding to the first USB link and the second USB link are different.

[0027] Based on the USB connection mode switching device provided in the embodiment of the present application, during use, the user only needs to switch the channel switching component to the corresponding side to control its output end to output a high-level signal or a low-level signal. The USB switch can automatically control the USB interface to access the corresponding USB link, thereby facilitating the communication connection between the external device and the display device, and improving the flexibility of the connection between the USB interface and the display channel. When the operating system of the display device changes and the USB link needs to be switched, the user no longer needs to perform plug-in operations, thereby optimizing the user experience.

[0028] In some embodiments, the channel switching component includes a first pin, a second pin, and an output pin. Figure 1 The first pin is used to connect to the power supply, the second pin is grounded, and the output pin is connected to the control pin of the USB switch. When the output pin is connected to the first pin, the output pin provides a high-level signal to the USB switch. When the output pin is connected to the second pin, the output pin provides a low-level signal to the USB switch, thereby controlling the USB interface to connect to different USB links. Based on the above structure, this embodiment changes the voltage of the output pin by controlling the connection relationship between different pins to output a high-level signal or a low-level signal to the USB switch, resulting in a simple structure and low design cost.

[0029] Please combine Figure 2 , the channel switching assembly provided in the embodiment of the present application includes a dip switch, the toggle member of the dip switch is made of insulating material. Figure 3 As shown, the toggle of the channel switching assembly can be located near the USB interface. The position of the toggle can indicate to the user which USB link the USB interface is currently connected to. For example, if the toggle is located on the left side, it indicates that the USB interface is currently connected to the first USB link, while if it is located on the right side, it indicates that the USB interface is currently connected to the second USB link. The toggle can also be located on the outer surface of the display device, in a convenient position for user operation, so that the user can easily switch the USB link corresponding to the USB interface by controlling the toggle when necessary.

[0030] For example, in the example of the embodiment of the present application, the display device can be a large-screen all-in-one machine with an OPS host. Combined with the functions of the OPS host (assuming that the OPS host is a Windows operating system and the large screen itself is an Android operating system), the large-screen all-in-one machine can support both the Android operating system and the Windows operating system, and the two operating systems respectively correspond to display channels. Based on this, the first USB link can be a switchable USB link, and the second USB link can be a fixed USB link. When the USB interface is connected to the switchable USB link, the USB interface can switch with the display channel, so that the external device connected through the USB interface can switch the display channel accordingly with the switching of the current operating system; when the USB interface is connected to the fixed USB link, the external device connected through the USB interface can be fixedly connected to a certain operating system, for example, so that the network card connected to the USB interface is mounted separately under the Windows system corresponding to the OPS host. When the display device switches to the large-screen Android system, the USB link of the USB interface will not change with the switching of the display channel. It is understandable that the Android system and the Windows system provided in the embodiments of the present application are merely examples for convenience of explanation and are not limitations thereto. In other cases, the display device may also support multiple other systems, such as macOS or Linux, or Windows and Windows in a sandbox, etc.

[0031] Please combine Figure 3An embodiment of the present application provides an example of a USB switch. As shown in the figure, the USB switch includes a control unit, a USB2.0 switch, and a USB3.0 switch. The control unit can control the USB2.0 switch and the USB3.0 switch to be turned on based on a received high-level signal, so that the USB interface supports both USB2.0 and USB3.0 transmissions when connected to a first USB link. The control unit can also control the USB2.0 switch to be turned on and the USB3.0 switch to be turned off based on a received low-level signal, so that the USB interface supports only USB2.0 transmissions when connected to a second USB link. For example, when a user needs to connect a device such as a wireless keyboard and mouse through the USB interface and needs these devices to switch connection channels in response to changes in the operating system, the user can choose to operate the channel switching component so that the input end of the channel switching component outputs a high-level signal to the control unit, thereby controlling the USB2.0 switch and the USB3.0 switch to be turned on and in normal working order. When the USB interface is connected to an external device such as a wireless keyboard and mouse, the USB interface connects to the adapted display channel in accordance with the current operating system, and supports switching the connected display channel in response to changes in the system. When the user needs to connect the network card and other devices required for the continuous download task through the USB interface, and needs to fix it under the display channel of a certain system to avoid the channel connected to the network card being disconnected due to the switching of the display channel, he can choose to operate the channel switching component so that the input end of the channel switching component outputs a low-level signal to the control unit, thereby controlling the USB2.0 switch to be fixed under the display channel of a set system and controlling the USB3.0 switch to be disconnected. When the USB interface is connected to the network card, it can be mounted separately under the display channel of the Windows system corresponding to the OPS host through this USB2.0 link, and will not participate in the process of switching with the channel. This solution, combined with the structure of the USB2.0 switch and the USB3.0 switch, can provide USB2.0 and USB3.0 link switching with the display channel when receiving a high-level signal, and can make the USB2.0 link mounted separately under a fixed display channel when receiving a low-level signal, and will not change with the switching of the display channel, so as to meet the use requirements of the USB interface in different situations.

[0032] In some embodiments, the above-mentioned USB switch also includes a USB hub, so that the USB2.0 switch and the USB3.0 switch can be connected to the USB interface through the USB hub. By setting up the USB hub, the USB2.0 switch and the USB3.0 switch can be connected at the same time using one USB interface, saving USB interface resources on the display device.

[0033] In some embodiments, the power supply is used to provide a 3.3V voltage to the channel switching component. Since 3.3V power supply technology is highly mature and widely used in various electronic devices, the use of a 3.3V power supply voltage in this solution not only provides a stable and reliable power supply, but also seamlessly compatibility with many existing components and devices, high compatibility with display devices, and can control design costs.

[0034] In some embodiments, the apparatus further includes an indicator light disposed on an outer surface of the display device, the indicator light being configured to indicate whether the channel switching component currently corresponds to a high level or a low level. The indicator light can provide a user with an intuitive prompt, enabling the user to quickly and conveniently determine the USB link currently corresponding to the channel switching component, thereby optimizing the user experience.

The USB switch can control the USB interface to access different USB links based on the high-level signal or low-level signal received, thereby adapting to USB connection modes with different display requirements. When the display requirements change, the display channel that needs to be adapted also changes.
