The communication motherboard 8 sends instructions to the control board 9. Each control board communicates back with each other through serial communication to determine its own level and the number of the power bank to which each level belongs. Through the cooperation of the communication motherboard 8 and the control board 9, the transmission of instructions and the return of information are realized. Through the serial communication between the control boards, the level and number are determined.
[0032] The power board connects to the communication motherboard 8 via a 2P ribbon cable. The communication motherboard 8 then transmits power to the control board 1 9, control board 2 10, and control board 3 11 via a 6P ribbon cable to power each sub-unit. The outer sides of the charging cabinet sub-unit 1 3, charging cabinet sub-unit 2 4, and charging cabinet sub-unit 3 5 adopt a rounded structure, while the front side uses a raised plate-like structure and a rounded rectangular edge structure. The front opening edge is rounded. The combination of the outer rounded structure and the front edge structure improves safety. The rounded edge of the opening avoids scratches when taking out or putting in the shared power bank 7.
[0033] During operation, the communication motherboard 8 coordinates the work of each control board. The control board manages the shared power banks 7 at the corresponding level according to the instructions. Users can take and put in the shared power banks 7 through the front opening. The level setting meets the capacity requirements of more power banks. Serial port cascading realizes unified management.
[0034] The number of storage slots is increased by setting up the main unit 2 and sub-units of the charging cabinet. Electrical connections and signal and power transmission between units are realized through 6P ribbon cables. The hierarchy and numbering are determined by communication between control boards, so as to realize the large capacity of the shared charging cabinet and efficient unified management.
[0035] Reference Figure 1 and Figure 2 A labeling plate 6 is fixedly connected to the front of the main unit 2 of the charging cabinet. The four corners of the labeling plate 6 are rounded.

The top front of the control board 9 has a serial port 12, and the bottom front of the control board 9 has a main serial port 13. After receiving instructions, the control board 9 of the first-layer charging cabinet sub-unit 3 transmits information back to the communication main board 8 via the serial port 12. It then sends corresponding instructions to the control board 10 of the second-layer charging cabinet sub-unit 4 via the main serial port 13 and receives information from the control board 10. The front top of the control board 2 10 is provided with the control board serial port 2 14, and the front bottom of the control board 1 9 is provided with the control board main serial port 2 15. The control board 2 10 of the second layer charging cabinet sub-unit 2 4 receives the instructions sent by the control board 1 9 of the first layer charging cabinet sub-unit 1 3 through the control board serial port 2 14 and then sends the information back to the first layer control board 1 9. It sends the corresponding instructions to the control board 3 11 of the third layer charging cabinet sub-unit 3 5 through the control board main serial port 2 15 and receives the information back from the control board 3 11.
[0036] The front top of the control board 311 is equipped with the control board serial port 316, and the front bottom of the control board 311 is equipped with the control board main serial port 317. The control board 311 of the third layer charging cabinet sub-unit 35 receives the instructions sent by the control board 210 of the second layer charging cabinet sub-unit 24 through the control board serial port 316 and sends the information back to the second layer control board 210. It sends the corresponding instructions to the next layer sub-unit control board through the control board main serial port 317 and receives the information back from the next layer sub-unit control board. If no information is received within the specified time, the layer is considered to be the final sub-unit, and the initialization sub-unit process is completed.
[0037] Specifically, the front panel 6 of the main unit 2 of the charging cabinet is made of acrylic material, and the four corners are rounded. Users can scan the QR code on it to rent and return the power bank. The rental and return operation can be conveniently initiated through the combination of the panel 6 and the QR code.
[0038] The communication motherboard 8 on the rear side of the main unit 2 of the charging cabinet communicates with the control board 9 of the sub-unit 3 of the charging cabinet via the TX and RX signal lines in the 6P ribbon cable. The control board at the top front of the control board 9 participates in signal transmission through serial port 12 and the main serial port 13 at the bottom front of the control board. The control board at the top front of the control board 10 participates in signal transmission through serial port 14 and the main serial port 15 at the bottom front of the control board. The communication motherboard 8 sends instructions to the control board 9. The control board 9 returns information through serial port 12 and sends instructions to the control board 10 through the main serial port 13 and receives the returned information. The control board 10 receives instructions from serial port 14 and returns information to the control board 9. It sends instructions to the control board 11 through the main serial port 15 and receives the returned information. Through the cooperation of each control board and the serial port, the instruction transmission and information return are realized, and the level and the corresponding power bank number are determined.
[0039] The power board connects to the communication motherboard 8 via a 2P ribbon cable. The communication motherboard 8 then supplies power to each control board via the 5V power line and GND ground line in the 6P ribbon cable. Each sub-unit adopts a smooth structure on the outside and a raised plate-like structure and a smooth rectangular edge structure on the front. The opening edges are rounded. The combination of the outer and front structures improves the safety of use. The edge treatment of the openings prevents scratches when taking out and putting in the shared power bank 7.
[0040] During operation, the communication motherboard 8 coordinates the work of each control board, and the control board manages the shared power banks 7 at the corresponding level. Users can take and put them in through the front opening. The level setting meets the large capacity requirements, and serial port cascading achieves unified management.
[0041] Working principle: The operation is initiated by scanning the QR code on the front panel 6 of the main unit 2 of the charging cabinet. The panel 6 is made of acrylic material and the four corners are rounded. The power board connects the power to the communication motherboard 8 inside the main unit 2 of the charging cabinet via a 2P ribbon cable. The communication motherboard 8 then transmits the power to the control board 9 of the charging cabinet sub-unit 1, the control board 10 of the charging cabinet sub-unit 2, and the control board 11 of the charging cabinet sub-unit 3 via a 6P ribbon cable. The 6P ribbon cable includes a 1P TX signal line, a 1P RX signal line, a 2P 5V power line and a 2P GND ground line to ensure stable power supply to each control board.
[0042] The communication motherboard 8 sends corresponding instructions to the control board 9 through the TX and RX signal lines in the 6P ribbon cable. After receiving the instructions, the control board 9 transmits information back to the communication motherboard 8 through the serial port 12 of its front top control board. At the same time, it sends corresponding instructions to the control board 10 through the main serial port 13 of the front bottom control board and receives the information transmitted back from the control board 10. The control board 10 receives the instructions sent by the control board 9 through the serial port 14 of its front top control board, transmits the information back to the control board 9, and then sends corresponding instructions to the control board 11 through the main serial port 15 of the front bottom control board. At the same time, it receives the information transmitted back from the control board 11. Through this signal transmission, each control board can determine its own level and the shared power bank 7 number of each level, so as to achieve precise management of shared power banks 7 at different levels.
[0043] Users can take out and put in the shared power bank 7 through the openings on the front of charging cabinet sub-unit 1 3, charging cabinet sub-unit 2 4 and charging cabinet sub-unit 3 5 according to the operation instructions. The outer side of these sub-units adopts a smooth structure, and the front side adopts a raised plate-like structure and a smooth rectangular edge structure. The edges of the front openings are all rounded to prevent users from being scratched when taking out and putting in the shared power bank 7.
[0044] Throughout the operation, the communication motherboard 8 coordinates the orderly operation of each control board. The control board manages the shared power banks 7 at the corresponding level according to the received instructions, including locking and unlocking operations. Through the hierarchical setting of the main unit 2 and each sub-unit of the charging cabinet, the number of power bank storage slots is increased, meeting the placement needs of more shared power banks 7. With the help of serial port cascading, unified management of all sub-units is achieved, eliminating the need for separate monitoring by additional accounts. The shared charging cabinet can provide users with convenient shared power bank 7 rental and return services, while adapting to large capacity needs and improving the safety of use and the efficiency of management.
