[0020] Example 1

[0021] Regarding the aforementioned problem: the USB interface of existing USB synchronous controllers is prone to dust accumulation when not in use, which can cause poor contact during subsequent use.

[0022] The solution is as follows: A port adapter structure for a four-port USB synchronous controller includes: an adapter controller 1, wherein the adapter controller 1 has four sets of equally spaced USB ports 2 internally; a wiring 7 is provided on the side of the adapter controller 1, and a connector 8 is provided on the side of the wiring 7; the connector 8 is electrically connected to the internal control motherboard of the adapter controller 1 through the wiring 7; each USB port 2 includes a metal frame 10, which is rectangular in structure, and upper and lower connecting plates 12 are provided at the top and bottom ends of the opening of the metal frame 10; and left and right connecting plates are provided at the left and right ends of the opening of the metal frame 10. 11. The upper and lower connecting plates 12 and the left and right connecting plates 11 are all inclined and fixedly connected to the metal frame 10. The bottom of the metal frame 10 is provided with a power connector 15, which is L-shaped. The lower part of the power connector 15 is provided with a positive terminal 19, a negative terminal 20, a positive data line 21, and a negative data line 22. The inner side of the metal frame 10 is provided with a contactor partition 18, which extends into the interior of the metal frame 10. The positive terminal 19, negative terminal 20, positive data line 21, and negative data line 22 at the lower part of the power connector 15 are all electrically connected to the internal control motherboard of the adapter controller 1. The adapter controller 1 has four equally spaced USB ports 2 inside. A wiring 7 is located on the side of the adapter controller 1, and a connector 8 is located on the side of the wiring 7. The connector 8 is electrically connected to the internal control motherboard of the adapter controller 1 through the wiring 7. Each USB port 2 includes a metal frame 10, which is rectangular in shape. Upper and lower connecting plates 12 are located at the top and bottom of the opening of the metal frame 10, and left and right connecting plates 11 are located at the left and right ends of the opening of the metal frame 10. The upper and lower connecting plates 12 and the left and right connecting plates 11 are all inclined and fixedly connected to the metal frame 10. The bottom of the adapter has a power connector 15 in an L-shape. The lower part of the power connector 15 has a positive terminal 19, a negative terminal 20, a positive data line 21, and a negative data line 22. A contactor partition 18 is located inside the metal frame 10 and extends into the interior of the metal frame 10. The positive terminal 19, negative terminal 20, positive data line 21, and negative data line 22 at the bottom of the power connector 15 are electrically connected to the internal control motherboard of the adapter controller 1. The adapter controller 1 solves the problems of existing USB synchronous controllers where USB devices must be inserted into specific interfaces, and mixed insertion can easily lead to signal conflicts or failures. It supports the insertion and automatic identification of any USB device, improving ease of use and flexibility. The design of the adapter controller 1 also considers user experience and safety, improving the stability and safety of user operation through anti-slip bumps 9 and baffles 3, and providing intuitive device status feedback through the display module 4 and indicator lights 6.

[0023] Further improvements, such as Figure 1As shown: The surface of the adapter controller 1 is equipped with a display module 4 and indicator lights 6, and the display module 4 and indicator lights 6 are electrically connected to the control motherboard inside the adapter controller 1. The display module 4 can display the working status of the adapter controller 1 and the information of connected devices in real time, which is convenient for users to monitor and manage. The indicator lights 6 can intuitively reflect the working status of the adapter controller 1 through different flashing states or colors, such as normal, fault, data transmission, etc., which improves the user's ease of use and perception of device status.

[0024] Further improvements, such as Figure 2 As shown: The USB port 2 is provided with slide rails 5 on both sides and baffles 3 on the surface of the slide rails 5. The baffles 3 are slidably connected to the slide rails 5. The baffles 3 can be slid open or closed as needed to protect the USB port 2 from dust, foreign objects and other damage. At the same time, it can also effectively cover the port when not in use, improving the aesthetics and cleanliness of the device.

[0025] Further improvements, such as Figure 2 As shown: The surface of the baffle 3 is provided with several sets of anti-slip protrusions 9. The design of the anti-slip protrusions 9 increases the roughness of the surface of the baffle 3, so that the user can better grip and control the baffle 3 when sliding it.

[0026] Further improvements, such as Figure 3 As shown: The metal frame 10 has side elastic tabs 14 on both sides and upper elastic tabs 13 and lower elastic tabs 17 on the upper and lower sides respectively. The side elastic tabs 14, upper elastic tabs 13 and lower elastic tabs 17 are all inclined inward towards the metal frame 10. The design of the elastic tabs allows the USB device to receive a certain elastic force and guidance when inserted, making it easier to align and smoothly insert into the port. At the same time, the elastic tabs can also fix the inserted device to a certain extent, preventing it from loosening or falling off due to vibration or external force, thus improving the stability and reliability of the connection.

[0027] Further improvements, such as Figure 3 As shown: Fixing blocks 16 are provided on both sides of the power connector 15 and the fixing blocks 16 are welded and fixed to the metal frame 10. The design of the fixing blocks 16 strengthens the connection strength and stability between the power connector 15 and the metal frame 10, ensuring that the power connector 15 will not loosen or fall off during long-term use or when subjected to external impact.

[0028] Example 2

[0029] The problem to be solved is that USB devices must be inserted into designated interfaces, and misinsertion can easily lead to signal conflicts or failures.

[0030] The solution is as follows:

[0031] In a further improvement, the adapter controller 1 adopts a matrix differential signal mode and dynamic impedance matching;

[0032] The matrix differential signal mode utilizes a matrix architecture to establish dynamic connections between multiple differential signal sources and signal destinations. An encoder converts multiple differential signals into digital streams, and a matrix switch is used to achieve dynamic routing and switching of the signals. According to the actual needs of the equipment and preset rules, the signals are transmitted to the corresponding destinations. A decoder restores the digital streams to differential signal outputs, ensuring accurate signal transmission and efficient processing.

[0033] In the process of signal transmission, the adapter controller 1 dynamically adjusts the circuit impedance value according to the real-time status of the signal source and load, reducing signal reflection and energy loss, and improving the efficiency and quality of signal transmission. Through dynamic impedance matching technology, the adapter controller 1 can ensure the stability and reliability of the signal during transmission and avoid signal attenuation or distortion caused by impedance mismatch.

[0034] Further improvements include full protocol compatibility for the adapter controller 1, supporting mixed use of USB devices ranging from 1.5Mbps to 480Mbps, including mechanical keyboards, optical mice, and USB flash drives;

[0035] Further improvements include phosphor bronze contacts and a gold-plated layer with a thickness of 3μm, providing a insertion / removal life of >10,000 cycles; an operating temperature range of -20℃ to 70℃, adapting to high-temperature workshop environments; standby power consumption of <0.5W (compared to >1W in traditional solutions); and dynamic voltage adjustment in active mode.

[0036] Furthermore, the innovative aspects of this solution will be explained.

[0037] Arbitrary port adapter and automatic structure identification

[0038] The adapter controller 1 has four equally spaced USB ports 2 inside. The upper and lower connecting plates 12 and the left and right connecting plates 11 at the opening of the metal frame 10 of each USB port 2 are set at an angle to form a guide structure. Together with the contactor partition 18 inside the metal frame 10, it can guide the USB device to be inserted smoothly and accurately connect to the positive terminal 19, negative terminal 20, positive data line 21 and negative data line 22 of the power socket 15. It realizes automatic identification and signal transmission when any port is inserted, which solves the problem of devices needing to be inserted into a specified interface and easy conflicts when mixed insertion in the prior art.

[0039] The side elastic plates 14 on both sides of the metal frame 10, and the upper elastic plates 13 and lower elastic plates 17 on the upper and lower sides are all inclined inward. When the device is inserted, the elastic plates provide elastic force, which can not only help fix the device, but also adapt to the insertion of different specifications of devices, further improving the flexibility of port adaptation.

[0040] Dustproof and Operation Optimization Design

[0041] Slide rails 5 are provided on both sides of the USB port 2. A cover 3 is slidably connected to the slide rails 5. When the port is not in use, the cover 3 can be slid to cover the port to prevent dust accumulation and avoid poor contact during subsequent use. The anti-slip bumps 9 on the surface of the cover 3 increase friction, making it easier for users to operate when sliding the cover 3 and improving the stability of use.

[0042] Status feedback and safety design

[0043] The display module 4 and indicator lights 6 on the surface of the adapter controller 1 are electrically connected to the internal control motherboard. The display module 4 can display the device connection status, working parameters and other information in real time. The indicator lights 6 provide intuitive feedback on the device operation status (such as normal operation, data transmission, fault prompts, etc.) through different colors and flashing modes, which makes it easier for users to monitor the device status and improve the safety of use.

[0044] Signal transmission and performance optimization technology

[0045] It adopts a matrix-style differential signal mode, uses a matrix architecture to dynamically connect multiple differential signal sources and destinations, converts multiple differential signals into digital streams through an encoder, realizes dynamic routing and switching of signals through a matrix switch, and then restores them to differential signal output by a decoder, ensuring accurate signal transmission and efficient processing when any port is plugged into a device, and avoiding signal conflicts.

[0046] By combining dynamic impedance matching technology, the circuit impedance value is dynamically adjusted according to the real-time status of the signal source and load, reducing signal reflection and energy loss, improving the stability and reliability of signal transmission, and reducing signal attenuation or distortion caused by impedance mismatch.

[0047] Specifically, a comparison of relevant test data and practical application data for this solution.

[0048]

[0049] Data Validity Statement

[0050] Test environment: Signal collision rate and insertion time tests were conducted in a constant temperature (25℃) laboratory free from strong electromagnetic interference; dust accumulation tests were conducted in a simulated daily office environment (airborne dust concentration approximately 0.5 mg / m³). 3 The standby power consumption test was conducted at a standard voltage (220V±10%).

[0051] Sample size: Each test had ≥50 samples to avoid random errors. The average value of the data was taken to ensure statistical significance.

[0052] Comparison criteria: Existing technical solutions are selected from mainstream four-port USB synchronous controllers on the market and compared with the present invention under the same equipment (such as USB flash drives, mice, and keyboards of the same brand) and the same operating procedures to ensure that the variables are unique.

[0053] Testing tools: Signal collision rate was detected using a professional signal analyzer (such as Keysight N9020A); insertion time was timed using a stopwatch; dust accumulation was measured using a precision electronic balance (accuracy 0.1mg); standby power consumption was monitored in real time using a power meter (such as Hioki 3169).

[0054] Working Principle: The user inserts a USB device into any of the USB ports 2 of the adapter controller 1. Due to the contactor baffle 18 and elastic sheet inside the port, the device is guided and fixed, ensuring a stable connection. The adapter controller 1 identifies the type of device inserted through its internal control motherboard and displays the device connection status via the display module 4 or indicator light 6. The adapter controller 1 employs a matrix differential signal mode and dynamic impedance matching technology. After the device is inserted, the controller converts multiple differential signals into a digital stream using an encoder, and uses a matrix switch to achieve dynamic signal routing and switching. Based on the actual needs of the device and preset rules, the signal is transmitted to the corresponding destination. The decoder restores the digital stream to a differential signal output, ensuring accurate signal transmission and efficient processing. During signal transmission, the adapter controller 1 dynamically adjusts the circuit impedance value according to the real-time status of the signal source and load. This helps reduce signal reflection and energy loss, improving signal transmission efficiency and quality. Through dynamic impedance matching technology, the adapter controller 1 ensures signal stability and reliability during transmission, avoiding signal attenuation or distortion caused by impedance mismatch. The adapter controller 1 solves the problems of existing USB synchronization controllers where USB devices need to be inserted into specific interfaces, and mixed insertion can easily lead to signal conflicts or failures. It supports the insertion and automatic identification of any USB device, improving ease of use and flexibility. The design of the adapter controller 1 also considers user experience and safety, improving the stability and safety of user operation through anti-slip bumps 9, baffles 3, etc., and providing intuitive device status feedback through display module 4 and indicator lights 6.
