[0033] Finally, a three-dimensional performance cloud map evaluation report including electrical characteristics, mechanical life, and thermodynamic parameters is generated.
[0034] The beneficial effects of the present invention are as follows:
[0035] Compared with existing docking stations, the present invention achieves high integration through a precisely designed outer shell and inner bracket structure. The cavity design in the inner bracket not only effectively utilizes the limited space but also ensures the orderly arrangement of each functional module (such as the main control module, interaction module, connection unit, etc.) through the rectangular cross-sectional shape and the division of four fixed areas. This not only facilitates assembly and maintenance but also greatly reduces the overall volume, making the docking station more compact and portable, suitable for desktop use without taking up too much space. Through the design of the output switching module and its docking module, the docking station can intelligently switch the electrical signal connection between the first connection unit and the second connection unit. This design allows users to flexibly select different devices or power cords according to actual needs without having to frequently change physical interfaces or carry multiple expansion devices. In addition, the application of gallium nitride material further improves the charging efficiency and safety due to its high efficiency and low heat generation characteristics, meeting the fast charging requirements of various devices. Furthermore, the present invention can select the required connection area according to user usage and can disconnect the power supply when not in use. Under the action of the output switching module, the main control module is not connected to the first and second connection units, ensuring safety.
[0036] The interaction module is directly exposed outside the outer shell through the interaction interface, greatly improving the convenience of user operation. Users can directly perform functions such as operation settings and status viewing through the intuitive interface without having to open the device or rely on additional software tools. This instant feedback mechanism not only simplifies the operation process but also enhances the user experience, making the docking station more intelligent and user-friendly. The present invention adopts a modular design, and key components such as the main control module, interaction module, and connection unit can be installed and disassembled relatively independently. This design facilitates users to upgrade or replace modules according to actual needs, extends the service life of the product, and reduces maintenance costs at the same time.
[0037] Considering the high power density and high-efficiency energy conversion characteristics of gallium nitride materials, the docking station pays special attention to heat dissipation performance in its internal structure design. Through reasonable air duct design, heat sinks and other measures, the heat generated during operation is effectively dispersed, ensuring the stable operation of the device under high load. This not only protects the internal electronic components from overheating damage, but also extends the service life of the overall system. With its multi-port design, high-efficiency charging, flexible connection and excellent user interaction experience, the docking station is suitable for a variety of scenarios, including but not limited to home office, business travel, education and learning, etc. Whether it is charging multiple devices such as laptops, tablets, mobile phones at the same time, or quickly presenting materials in a meeting, it can easily handle them, greatly improving the efficiency of work and life. The charging module using gallium nitride technology has a higher energy conversion efficiency compared with traditional silicon-based materials, reducing energy waste.
[0038] A test method for an interactive multi-port desktop gallium nitride charging docking station. Through the integration of a test control module, a test P1 module, a test P2 module, a test output module and a test judgment module, the test system realizes comprehensive and accurate test coverage of the gallium nitride charging docking station. In step S1, a dynamic resonance compensation circuit is used for phase calibration and parasitic parameter simulation compensation, which not only improves the accuracy of the test, but also effectively reduces the current harmonic distortion rate, ensuring the stability and purity of the output power signal. Secondly, the interactive interface design in the scheme enables users to conveniently send switching commands to the main control module, and drives the linear drive module to actuate through the transmission control module (step S2). This not only improves the automation level of the test, but also significantly enhances the flexibility and operability of the test. At the same time, the application of a displacement sensor (step S3) ensures the accurate verification of the X-axis travel of the bidirectional connector and the contact connector, further guaranteeing the reliability and stability of the connection. Moreover, the real-time acquisition function in step S4 covers multi-dimensional data such as the zero-voltage switching waveform integrity of the gallium nitride switch array, the multi-channel current distribution deviation value, and the surface temperature rise gradient of the graphene heat conduction layer, providing strong support for comprehensively evaluating the electrical characteristics and thermodynamic performance of the docking station. Finally, when evaluating the overall performance of the system (step S5), through multiple rounds of plugging and unplugging durability pressure tests, waveform stability tests under asymmetric load conditions, and self-recovery ability tests under sudden surge interference, this scheme not only verifies the mechanical life and electrical stability of the docking station, but also ensures its reliable operation in complex environments.

[0059] Such as Figures 1 to 9As shown in the figure, in an embodiment of the present invention, there is provided an interactive multi-port desktop gallium nitride charging dock, which includes a housing 1, an inner bracket 2, a first end cap 3, a second end cap 4, a main control module 5, an interaction module 6, a first connection unit 7, a second connection unit 8, and an output switching module 9. The housing 1 is provided with an accommodation cavity 11, the inner bracket 2 is arranged in the accommodation cavity 11, and the first end cap 3 and the second end cap 4 are respectively arranged at both ends of the accommodation cavity 11 to fix the inner bracket 2 in the accommodation cavity 11. The inner bracket 2 is centrally provided with a cavity 21, the cross-sectional shape of the cavity 21 is rectangular and is respectively provided with a first fixing area 22, a second fixing area 23, a third fixing area 24, and a fourth fixing area 25 on four sides. The main control module 5 and the interaction module 6 are respectively arranged on both sides of the first fixing area 22, and the interaction interface of the interaction module 6 is exposed outside the housing 1. The output switching module 9 is provided with a docking module 91, one end of the docking module 91 is electrically connected to the main control module 5, the first connection unit 7 and the second connection unit 8 are both arranged in the third fixing area 24, and the third fixing area 24 is opposite to the first fixing area 22. The output switching module 9 is used to drive the docking module 91 to reciprocate between the first connection unit 7 and the second connection unit 8 to switch the electrical signal connection between the docking module 91 and the first connection unit 7 or the second connection unit 8, and the main control module 5 is connected to the first connection unit 7 or the second connection unit 8 through the docking module 91. In this embodiment, through the precisely designed structures of the housing 1 and the inner bracket 2, high integration is achieved. The design of the cavity 21 in the inner bracket 2 not only effectively utilizes the limited space, but also ensures the orderly arrangement of each functional module (such as the main control module 5, the interaction module 6, the connection unit, etc.) through the rectangular cross-sectional shape and the division of the four fixing areas. It is not only convenient for assembly and maintenance, but also greatly reduces the overall volume, making the docking station more compact and portable, suitable for desktop use and not occupying too much space. Through the design of the output switching module 9 and its docking module 91, the docking station can intelligently switch the electrical signal connection between the first connection unit 7 and the second connection unit 8. This design allows users to flexibly select to connect different devices or power cords according to actual needs, without the need to frequently replace physical interfaces or carry multiple expansion devices. In addition, the application of gallium nitride material further improves the charging efficiency and safety due to its high efficiency and low heat generation characteristics, meeting the requirements of fast charging for various devices.
[0060] In the above embodiments, the interaction module 6 is directly exposed outside the housing 1 through the interaction interface, greatly improving the convenience of user operation. Users can directly perform functions such as operation settings and status viewing through the intuitive interface without opening the device or relying on additional software tools. This instant feedback mechanism not only simplifies the operation process but also enhances the user experience, making the docking station more intelligent and user-friendly. The present invention adopts a modular design, and key components such as the main control module 5, the interaction module 6, and the connection unit can be installed and disassembled relatively independently. This design facilitates users to upgrade or replace modules according to actual needs, extends the service life of the product, and reduces the maintenance cost at the same time.
[0061] A shock-absorbing and anti-slip pad 12 is provided at the bottom of the housing 1. The housing 1 is formed by extruding a rectangular aluminum alloy profile. An assembly positioning chute 13 is provided on the inner wall of the placement cavity 11, and an assembly positioning slide bar 25 is provided on the outer wall of the inner bracket 2. The assembly positioning slide bar 25 is used to cooperate with the assembly positioning chute 13 to slidably fit the inner bracket 2 in the placement cavity 11. In this embodiment, the shock-absorbing and anti-slip pad 12 at the bottom of the housing 1 not only enhances the stability of the docking station during use, effectively preventing sliding or tipping caused by accidental touch or an uneven desktop, but also protects the internal electronic components from external vibrations through its shock-absorbing performance, extending the service life of the device. The housing 1 itself is formed by extruding a rectangular aluminum alloy profile. This material selection not only endows the docking station with the characteristics of being sturdy and durable but also ensures good heat dissipation performance, helping the gallium nitride charger to maintain a stable operating temperature during high-power output, improving the overall safety and reliability. The assembly positioning chute 13 provided on the inner wall of the placement cavity 11 cooperates with the assembly positioning slide bar 25 on the outer wall of the inner bracket 2 to achieve precise sliding fit of the inner bracket 2 in the placement cavity 11. This design not only simplifies the installation and disassembly process of the inner bracket 2, improves the assembly efficiency, but also ensures the stability of the inner bracket 2 during use, avoiding problems such as poor contact or damage caused by loosening.
[0062] Threaded connection posts 111 are provided on the bottom surface of the placement cavity 11. Threaded counterbores 251 are provided in the fourth fixing area 25, and the inner bracket 2 is fixed in the placement cavity 11 by screws passing through the threaded counterbores 251 and connecting with the threaded connection posts 111. In this embodiment, through precise thread fitting, the stable installation of the inner bracket 2 in the placement cavity 11 is ensured. The tight engagement of the threaded connection posts 111 and the threaded counterbores 251 not only provides sufficient connection strength but also effectively prevents the inner bracket 2 from loosening or displacing during use, thus ensuring the stability and reliability of the overall structure of the charging docking station.
[0063] On one side of the housing 1, there are provided a display fixing groove 14 and a heat dissipation groove 15. The heat dissipation groove 15 corresponds to the main control module 5, and the display fixing groove 14 is used to fix the interaction module 6. In the first fixing area 22, there is a through groove 221, and a heat transfer fin 222 is arranged in the through groove 221. The heat transfer fin 222 is used to fit one side of the main control module 5 with the inner wall surface of the heat dissipation groove 15, so as to transfer the heat of the main control module 5 to the heat dissipation groove 15 for heat dissipation. In this embodiment, by carefully arranging the display fixing groove 14 and the heat dissipation groove 15 on one side of the housing 1, the efficient integration of functionality and heat dissipation performance is achieved. The display fixing groove 14 accurately positions and firmly fixes the interaction module 6, ensuring the stable display and smooth interaction of the user interface, and greatly improving the user experience. At the same time, the heat dissipation groove 15 directly corresponds to the main control module 5, effectively managing the heat dissipation of its high-heat area. Through the through groove 221 arranged in the first fixing area 22 and the heat transfer fin 222 inside it, one side of the main control module 5 is closely fitted with the inner wall surface of the heat dissipation groove 15. This design not only greatly increases the heat conduction area but also significantly improves the heat transfer efficiency, enabling the heat generated by the main control module 5 during operation to be quickly and effectively dissipated through the heat dissipation groove 15. In this embodiment, a three-dimensional stacked architecture composed of multiple groups of GaN chips is adopted. This design greatly improves the power density, enabling the charging dock to provide efficient and stable power output in a compact space. By driving multiple parallel charging channels on the first connection unit 7 or the second connection unit 8, this module effectively meets the need for multiple devices to be charged simultaneously, improving the user's convenience. The line voltage crossing technology implemented by the main control module 5, especially the horizontally arranged gallium nitride switch array it contains, realizes multi-channel zero-voltage switching. This characteristic not only reduces energy loss but also significantly improves the response speed and stability of the system. The graphene layer or aluminum nitride composite heat conduction layer covering the surface of each GaN chip effectively improves the heat conduction efficiency, ensures the stable operation of the chip at high power output, and extends the service life of the device. In addition, the introduction of the dynamic resonance compensation circuit enables the system to adaptively match the parasitic parameters in the power range of 10 - 120W, further optimizing the power transmission efficiency, reducing harmonic interference, and improving the electromagnetic compatibility of the overall system.
[0064] The first end cover 3 is provided with a first fastening member 31, and the second end cover 4 is provided with a second fastening member 41.

The second end cover 4 is fastened to one end of the placement cavity 11 through the second fastening member 41 and is opposite to the first end cover 3. In this embodiment, the first fastening member 31 equipped on the first end cover 3 is tightly fastened to one end of the placement cavity 11, which not only ensures the firmness of the end cover fixation, but also effectively prevents loosening caused by accidental touch or vibration, ensuring the safe operation of the internal circuit and components. At the same time, the second end cover 4 has a unique design, integrating the second fastening member 41 and the connecting wire 42. Among them, the second fastening member 41 also ensures the stable connection between the end cover and the placement cavity 11, forms a symmetrical layout with the first end cover 3, and enhances the overall structural stability of the docking station. The setting of the connecting wire 42 is even more ingenious. One end of it is electrically connected to the main control module 5, providing a necessary power transmission path for the multi-port charging function of the docking station, ensuring stable and efficient power supply to each charging interface.
[0065] Refer to Figure 7As shown, the first connection unit 7 includes a first connection plate 71 and a plurality of first connection ports 72. The first connection plate 71 is provided with a first contact vertical plate 73, and a first contact connector 731 is arranged on the first contact vertical plate 73.

In this embodiment, the design of the first connection unit 7 and the second connection unit 8 realizes efficient and stable signal and power transmission through their respective equipped connection plates and connection ports. Both the first contact connector 731 and the second contact connector 831 can be closely connected to the docking module 91, thereby ensuring seamless docking with the main control module 5 and greatly improving the data transmission rate and charging efficiency. Secondly, the setting of the first port groove 241 and the second port groove 242 not only effectively fixes the first connection port 72 and the second connection port 82, but also enables these ports to extend stably to the side surface of the housing 1, facilitating the user to perform plugging and unplugging operations. This design not only enhances the structural stability but also improves the user experience.
