[0025] As described in the background section, an interactive device is a systematic device that integrates sensing technology, data processing, execution feedback, and hardware carrier, with human-computer interaction at its core. In related technologies, to broaden the application scenarios of interactive devices, they are typically equipped with USB and wireless interfaces. However, in actual use, the USB 3.0 signal generated by the USB interface and the wireless signal generated by the wireless interface are prone to mutual interference. A common solution is to physically increase the distance between the USB interface and the wireless interface to reduce mutual interference. However, interactive devices usually have compact structural design requirements, making it impossible to reserve sufficient distance between the USB interface and the wireless interface, thus making the aforementioned interference solutions based on distance optimization difficult to apply.

[0026] Reference Figures 1 to 3 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides an interactive device. The interactive device includes an interactive body 100 and a control unit 200, with the control unit 200 disposed on the interactive body 100. The control unit 200 includes a control element 210 and an interface element 220, with the control element 210 electrically connected to the interactive body 100 and the interface element 220 electrically connected to the control element 210.

[0027] The interface device 220 includes a USB interface 221 and a wireless interface 222. The USB interface 221 is used to transmit USB 2.0 signals and USB 3.0 signals, and the wireless interface 222 is used to transmit wireless signals. A USB 3.0 switch 230 is electrically connected between the USB interface 221 and the control device 210. The USB 3.0 switch 230 has an on state and an off state and is used to control the on and off of the USB 3.0 signal transmission path.

[0028] When the wireless interface 222 transmits wireless signals, the USB 3.0 switch 230 is in the off state, and the USB interface 221 is used to transmit USB 2.0 signals; when the wireless interface 222 stops transmitting wireless signals, the USB 3.0 switch 230 is in the on state, and the USB interface 221 is used to transmit USB 3.0 signals.

[0029] In this embodiment, the interactive device is an interactive screen, a data acquisition terminal, or an industrial touch panel; the interactive body 100 is a combination of a touch display screen in the interactive screen, a touch panel in the data acquisition terminal, or a display module and operation buttons in the industrial touch panel. USB stands for Universal Serial Bus; the USB interface 221 is a physical interface, such as a Type-A interface or a Type-C interface. The USB interface 221 is electrically connected to the control unit 210 and is used to connect external devices, such as a USB flash drive. The wireless interface 222 is the exposed interface 223 or antenna part of the wireless communication module, such as the antenna interface of a WiFi module (WiFi stands for Wireless Fidelity), the antenna of a Bluetooth module, or the signal transceiver interface of a radio frequency module. The wireless interface 222 is electrically connected to the control unit 210 through the wireless communication module for wireless communication with external devices. Specifically, the control unit 210 can obtain the status information of the wireless interface 222 transmitting or suspending wireless signal transmission, and send a control signal to the USB 3.0 switch 230 according to the information to realize the state switching of the USB 3.0 switch 230. The USB 3.0 switch 230 is a high-speed signal switch chip that supports the USB 3.0 protocol. It controls the opening and closing of the internal path through the pin level to realize the switching between USB 3.0 signals and USB 2.0 signals.

[0030] When the wireless interface 222 is operational, the USB 3.0 switch 230 is in the off state, allowing the USB interface 221 to transmit only the USB 2.0 signal, which has less interference with the wireless signal, thus reducing the risk of interference between the USB 3.0 signal and the wireless signal at the source. When the wireless interface 222 is not operational, the USB 3.0 switch 230 is in the on state, restoring the transmission of the USB 3.0 signal. This structural design, while ensuring signal quality, does not require increasing the distance between the USB interface 221 and the wireless interface 222, thereby helping to meet the requirement of a compact structure for interactive devices.

[0031] In addition, the USB 3.0 switch 230 can automatically adapt to the working status of the wireless interface 222 without manual switching, which improves the flexibility of switching operations; at the same time, interference isolation is achieved through the control of the USB 3.0 switch 230, eliminating the need for complex shielding or filtering designs and reducing design and manufacturing costs.

[0032] Reference Figure 1 and Figure 2In one embodiment, the interactive body 100 has an installation space 110, and the control unit 200 is disposed in the installation space 110; the interactive body 100 is provided with a first external opening 120 that connects the inside and outside of the installation space 110, and the USB interface 221 is used to electrically connect to an external device through the first external opening 120.

[0033] In this embodiment, the installation space 110 refers to the internal hollow space of the interactive body 100. This internal hollow space can be the internal hollow space of the overall structure of the interactive body 100, or it can be the internal hollow space of a part of the structure of the interactive body 100. The control unit 200 is fixedly installed in the installation space 110; the first external opening 120 extends from the outside of the installation space 110 into the installation space 110; the USB interface 221 can be entirely located in the installation space 110 and can be electrically connected to an external device by corresponding to the first external opening 120, or it can be electrically connected to an external device by inserting at least a part of its structure into the first external opening 120.

[0034] The installation space 110 not only provides physical protection for the control unit 200, reducing the impact of dust, moisture, and external impacts on it, but also makes the external structure of the interactive device more regular, thus meeting the requirements of compact design. Furthermore, the first exposed port 120 provides a channel for direct connection of external devices to the USB interface 221, allowing for quick plugging and unplugging of the USB interface 221 to external devices without disassembling the interactive body 100, thus improving the convenience of connection.

[0035] Reference Figure 1 and Figure 2 In one embodiment, the interface component 220 further includes a plurality of exposed interfaces 223, which are spaced apart from the USB interface 221 along a preset direction; the interactive body 100 is provided with a plurality of second exposed ports 130 that connect the inside and outside of the installation space 110, the number of second exposed ports 130 is greater than or equal to the number of exposed interfaces 223, and the exposed interfaces 223 are used to electrically connect to an external device through one of the plurality of second exposed ports 130.

[0036] In this embodiment, the preset direction is parallel to the width direction of the control unit 200. It should be noted that the preset direction may also be parallel to the length direction or other directions of the control unit 200. The second exposed opening 130 extends from the outside of the installation space 110 into the installation space 110; the number of second exposed openings 130 is the same as the number of exposed interfaces 223, and multiple exposed interfaces 223 are respectively provided in one-to-one correspondence with multiple second exposed openings 130.

[0037] The exposed interface 223 is electrically connected to the control unit 210 (see details). Figure 3Meanwhile, the exposed interface 223 can be entirely located within the installation space 110 and can be electrically connected to external devices by correspondingly being configured with the corresponding second exposed port 130, or it can be electrically connected to external devices by at least partially inserting its structure into the corresponding second exposed port 130. It should be noted that the number of second exposed ports 130 can also be greater than the number of exposed interfaces 223.

[0038] On the one hand, the multiple exposed interfaces 223, used in conjunction with the USB interface 221, allow the interactive device to connect to multiple external devices simultaneously, thus broadening the application scenarios of the interactive device.

[0039] On the other hand, the multiple exposed interfaces 223 and USB interfaces 221 are spaced apart along a preset direction and arranged in an orderly manner in conjunction with the second exposed port 130, which effectively reduces the risk of the exposed interfaces 223 being randomly distributed. This not only makes the external structure of the interactive device more regular and helps to meet the requirements of compact design, but also effectively improves the space utilization rate.

[0040] On the other hand, the number of second exposed ports 130 is greater than or equal to the number of exposed interfaces 223. During assembly, the corresponding second exposed ports 130 can be flexibly matched according to the actual position of the exposed interfaces 223, thereby reducing the assembly accuracy requirements. At the same time, if it is necessary to add exposed interfaces 223 in the future, there is no need to open additional second exposed ports 130, which improves the convenience of assembly operations.

[0041] Reference Figure 2 In one implementation, at least one of the types and structures of the plurality of exposed interfaces 223 remains different.

[0042] In this embodiment, the multiple exposed interfaces 223 can be HDMI interfaces (HDMI stands for High-Definition Multimedia Interface), DP interfaces (DP stands for Display Port), 3.5mm audio interfaces, RJ45 network ports (RJ45 stands for Registered Jack 45), or DC power interfaces (DC stands for Direct Current). They can also be the same interface with different structures. Specifically, any two exposed interfaces 223 may differ in at least one aspect of type and structure. It should be noted that this application does not prohibit two exposed interfaces 223 from being identical in both type and structure.

[0043] Exposed interfaces 223 of different types and / or structures have obvious differences in appearance and can be intuitively distinguished, which helps to reduce the risk of errors. At the same time, exposed interfaces 223 of different types and / or structures can be connected to different external devices, effectively increasing the variety of external devices that the interactive device can be connected to and broadening the usage scenarios of the interactive device.

[0044] Reference Figure 2 and Figure 3 In one embodiment, the interface 220 further includes at least one of an audio / video interface 224, a touch interface 225, a dot-screen interface 226, an OPS interface, and a front panel power supply interface 228.

[0045] In this embodiment, the interface component 220 includes an audio / video interface 224, a touch interface 225, a touch-screen interface 226, an OPS interface (OPS stands for Open Pluggable Specification), and a front-panel power supply interface 228. The audio / video interface 224 is used for electrical connection to external devices such as monitors and speakers to achieve audio / video signal output or input. The touch interface 225 and touch-screen interface 226 are used for electrical connection to external devices such as touchscreens and display panels to ensure accurate human-computer interaction. The OPS interface 227 is used for electrical connection to external devices such as OPS computer modules to enhance the computing and storage capabilities of the interactive device. The front-panel power supply interface 228 is used for electrical connection to the front operation panel to provide stable power. It should be noted that the interface component 220 may also include only one, two, three, or four of the following interfaces: audio / video interface 224, touch interface 225, touch-screen interface 226, OPS interface, and front-panel power supply interface 228.

[0046] The interface component 220 further increases the variety of external devices that the interactive device can connect to, thus broadening the application scenarios of the interactive device.

[0047] In addition, USB interface 221, wireless interface 222, exposed interface 223, touch interface 225, screen dot interface 226, OPS interface and front panel power supply interface 228 are arranged around the control unit 210.

[0048] Reference Figure 2 and Figure 3 In one embodiment, the control unit 200 further includes a multi-channel power amplifier 240, which is located on one side of the control unit 210 and is electrically connected to the control unit 210.

[0049] In this embodiment, the multi-channel power amplifier 240 is a modular integrated structure, including a signal input interface circuit, a signal processing unit, a multi-channel power amplification unit, a power supply circuit, and a signal output interface circuit. The multi-channel power amplifier 240 is used to amplify and precisely distribute the power of multi-channel audio signals and drive multiple speakers to work together to achieve a stereo surround sound effect.

[0050] The multi-channel amplifier 240 can amplify the audio signal and drive multiple speakers to achieve a stereo surround sound effect, thus enhancing the user's audiovisual experience.

[0051] Reference Figure 2 and Figure 3 In one embodiment, the control unit 200 further includes a power supply unit 250, which is located on one side of the control unit 210 and is electrically connected to the control unit 210.

[0052] In this embodiment, the power supply unit 250 can be a switching power supply module, a linear power supply module, or a power adapter. The power supply unit 250 provides stable power support to the control unit 210 and the interface unit 220, thereby improving the reliability of the operation of the control unit 200.

[0053] Reference Figure 2 and Figure 3 In one embodiment, the power supply component 250 includes at least one of an AC power supply 251, a DC power supply 252, and a backlight power supply 253.

[0054] In this embodiment, the power supply unit 250 includes an AC power supply 251 (AC stands for Alternating Current), a DC power supply 252 (DC stands for Direct Current), and a backlight power supply 253. The AC power supply 251 includes an input filter circuit, a rectifier circuit, a power factor correction circuit, and a control chip. The AC power supply 251 rectifies external power supplies (such as 220V or 110V) to provide the device with the required DC power. The DC power supply 252 includes an input filter circuit, a switch, an energy storage filter, a stabilization control chip, an output filter circuit, and a protection circuit. The DC power supply 252 converts the rectified DC power from the AC power supply 251 into the precise DC power required by the various components of the control unit 200. The backlight power supply 253 includes a PWM control chip (PWM stands for Pulse Width). Modulation (pulse width modulation), power switching transistors, boost circuit, buck circuit, current sampling circuit, and output interface; backlight power supply 253 is used to power the backlight module of the interactive body 100 to achieve precise control of backlight brightness. It should be noted that the control unit 210 may also have only one or both of the following: AC power supply 251, DC power supply 252, and backlight power supply 253.

[0055] The AC power supply 251, DC power supply 252, and backlight power supply 253 are designed to meet different power needs in the interactive device, which helps to achieve on-demand power supply, thereby matching different power supply requirements and ensuring the stable operation of various components in the interactive device.

[0056] Reference Figure 2 and Figure 3 In one embodiment, the control unit 200 further includes a mounting member 260, which has a connection line 261. The control member 210, the interface member 220, and the power supply member 250 are disposed on the mounting member 260. The control member 210 is electrically connected to the interface member 220 and the power supply member 250 through the connection line 261.

[0057] In this embodiment, the mounting component 260 is a PCB (Printed Circuit Board). The connecting line 261 is a conductive line pre-fabricated on the mounting component 260. The control component 210, interface component 220, and power supply component 250 are all fixedly mounted on the mounting component 260 and electrically connected to the connecting line 261. Furthermore, the multi-channel power amplifier 240 is fixedly mounted on the mounting component 260 and electrically connected to the connecting line 261. It should be noted that the mounting component 260 can also be a mounting plate or mounting frame; in this case, the connecting line 261 is a connecting wire.

[0058] Mounting component 260 provides a unified mounting platform for control component 210, interface component 220, and power supply component 250, enabling orderly arrangement of components, reducing the possibility of messy wiring, and standardizing the structural layout of control unit 200. Simultaneously, the built-in connecting cable 261 of mounting component 260 allows for direct electrical connection between components, eliminating the need for numerous external wires, shortening signal transmission paths, reducing electromagnetic interference and signal loss, and ensuring stable and reliable power supply and data signal transmission.

[0059] Reference Figures 2 to 4 In one embodiment, the mounting member 260 has a mounting surface 262, which is divided into a first mounting area 263 and a second mounting area 264 that are independent of each other. The control member 210 and the interface member 220 are disposed in the first mounting area 263, and the power supply member 250 is disposed in the second mounting area 264.

[0060] In this embodiment, the first mounting area 263 and the second mounting area 264 are arranged sequentially along a direction perpendicular to a preset direction (i.e., the length direction of the control unit 200). The multi-channel power amplifier 240 is disposed in the first mounting area 263.

[0061] On the one hand, installing the power supply component 250, control component 210, and interface component 220 in separate areas can effectively reduce the impact of electromagnetic interference generated by the power supply component 250 during operation on the signal processing of the control component 210 and the signal transmission of the interface component 220, thereby reducing the risk of signal distortion and functional failure, and ensuring the stable and coordinated operation of each component.

[0062] On the other hand, the power supply component 250 is prone to generating heat when it is working. Arranging it separately in the second installation area 264 helps to disperse heat dissipation with the control component 210 and the interface component 220, thereby reducing heat accumulation. At the same time, it also facilitates the planning of heat dissipation paths, reduces the temperature rise of the overall control unit 200, and extends the service life of each component.

[0063] On the other hand, placing the control component 210 and the interface component 220 in the first mounting area 263 and the power supply component 250 in the second mounting area 264 makes the various components arranged in a neat manner, which helps to improve assembly efficiency and maintenance efficiency.

[0064] Reference Figure 2 and Figure 4 In one embodiment, the mounting member 260 has a regular shape. In this embodiment, the mounting surface 262 of the mounting member 260 is rectangular. It should be noted that the shape of the mounting surface 262 of the mounting member 260 is not limited to a rectangle, but can also be a square, circle, ellipse, triangle or polygon, or other shapes that can be described or divided by standard geometric formulas, or a shape composed of multiple basic regular shapes.

[0065] The regularly shaped mounting component 260 not only facilitates manufacturing and processing, but also allows each component to make full use of the mounting surface 262 space of the mounting component 260, thereby reducing costs and minimizing the space occupied by the control unit 200.

[0066] In summary, implementing the interactive device provided in this embodiment has at least the following beneficial technical effects: When the wireless interface 222 is operational, the USB 3.0 switch 230 is in the off state, allowing the USB interface 221 to transmit only the USB 2.0 signal, which has less interference with the wireless signal. This reduces the risk of interference between the USB 3.0 signal and the wireless signal at the source. When the wireless interface 222 is not operational, the USB 3.0 switch is in the on state, restoring the transmission of the USB 3.0 signal. This structural design, while ensuring signal quality, does not require increasing the distance between the USB interface 221 and the wireless interface 222, thus helping to meet the requirement of a compact structure for interactive devices.

[0067] In addition, the USB 3.0 switch 230 can automatically adapt to the working status of the wireless interface 222 without manual switching, which improves the flexibility of switching operations; at the same time, interference isolation is achieved through the control of the USB 3.0 switch 230, eliminating the need for complex shielding or filtering designs and reducing design and manufacturing costs.

[0068] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. It should be noted that, for those skilled in the art, several equivalent obvious modifications and / or equivalent substitutions can be made without departing from the technical principles of this application, and these obvious modifications and / or equivalent substitutions should also be considered within the scope of protection of this application.
