[0018] like Figure 1 As shown, an automatic charging device for a lithium-ion tractor unit includes a parking station, a charger, and a charging plug 6. The charging plug 6 is connected to the lithium-ion battery via a charging circuit. The charger is fixed to the edge of the parking station. The charging port 5 of the charger is connected by wires and positioned on the edge of the travel rail of the lithium-ion tractor unit 1. The parking station is connected to the transfer rail of the transfer vehicle via a parking rail 10. The transfer rail is used for the operation of the transfer vehicle, which is towed by the tractor unit 1. The parking station has a positioning point corresponding to the tractor unit 1. At this positioning point, the charging plug 6 and the charging port 5 are connected to achieve lithium-ion battery charging. The parking station is independent of the transfer rail and does not affect the normal operation of other transfer vehicles during the charging process.

[0019] The charger is positioned at the edge of the parking station, without affecting the entry and exit of the tractor 1. The charger is connected to the charging port 5 via a connecting cable. The charging port 5 is positioned on the side of the parking track 10. Below the charging port 5 is a drive component 4, which can be a scissor-type hydraulic frame, a hydraulic cylinder, an electric actuator, or a pneumatic cylinder. This drive component 4 longitudinally moves the charging port 5 towards the charging plug 6 for insertion. The charging plug 6 is positioned on the side of the tractor 1. When the tractor 1 stops at the positioning point, the charging plug 6 is longitudinally aligned with the charging port 5. As the charging port 5 moves upward, it can electrically connect with the charging plug 6, preparing for charging.

[0020] In this embodiment, a flat, longitudinally extending mounting surface is provided on a side portion of the towing vehicle 1 for mounting the charging plug 6. Specifically, the charging plug 6 is correspondingly assembled on the sliding seat 3, a sliding bar 9 having a dovetail-shaped cross section is provided on the side portion of the towing vehicle 1, a longitudinally extending dovetail groove is provided on the sliding seat 3, and the sliding bar 9 is slidably assembled with the dovetail groove. A baffle directly above the sliding seat 3 is correspondingly arranged above the sliding seat 3, and an extrusion spring 7 is arranged between the baffle and the sliding seat 3, so that the charging plug 6 has a movement trend toward the charging socket 5. A limiting plate corresponding to the dovetail groove is arranged at the lower end of the sliding bar 9 to prevent the sliding seat 3 from slipping off.

[0021] Further, a sliding column 8 sleeved in the extrusion spring 7 is arranged above the sliding seat 3, the sliding column 8 passes upward through the baffle and is slidably assembled with the baffle. The charging plug 6 can be integrally formed with the sliding seat 3, and the connecting wire of the charging plug 6 can extend upward through the sliding column 8 and then be connected to the lithium battery charging circuit.

[0022] A positioning plate 2 corresponding to the positioning point is arranged at the parking station, the positioning plate 2 spans above the parking rail 10 and is supported by a stand column, the height of the positioning plate is matched with that of the towing vehicle 1, and a position sensor 11 facing the towing vehicle 1 is arranged on the positioning plate 2. The position sensor 11 can be a touch switch, which is triggered after the towing vehicle 1 abuts against the positioning plate 2, so as to confirm that the towing vehicle 1 is in place.

[0023] The position sensor 11, the charger and the driving member 4 are correspondingly connected to a controller. Further, a touch switch facing the charging socket 5 is arranged at an end of the sliding seat 3, and the touch switch is correspondingly connected to a control center of the towing vehicle 1.

[0024] Wherein the control center is configured to control the traveling of the towing vehicle 1, and the controller is configured to perform charging control. Information transmission is performed between the control center of the towing vehicle 1 and the controller through a wireless network, so that linkage can be realized and automatic charging can be performed. Specifically, the control center can monitor the power of the lithium battery, and automatically travels to the parking rail 10 when the power is insufficient. After the towing vehicle 1 abuts against the position sensor 11, the controller controls the driving member 4 to lift until the charging socket 5 is docked with the charging plug 6, the touch switch at the end of the sliding seat 3 is triggered, at this time the controller controls the charger to start, and the driving wheels of the towing vehicle 1 stop driving. Further, a self-locking device corresponding to the driving wheels is arranged on the towing vehicle 1 to self-lock the driving wheels during charging. Specifically, the structure of the driving wheels and the installation of the self-locking device can all adopt commercially available products, and no excessive limitation is made herein.

[0025] The tractor 1 is equipped with a lithium battery, which powers the drive wheels and control center. The charging circuit of the lithium battery is electrically connected to the charging plug 6. The charging plug 6 is a truncated cone shape with the small end facing down. The charging port 5 has a corresponding truncated cone-shaped slot with the small end facing down, which facilitates the connection between the charging plug 6 and the charging port 5. A first electrode protruding upward is provided at the bottom of the slot. The end of the charging plug 6 has a corresponding insertion hole for the first electrode. A second electrode corresponding to the first electrode is provided in the insertion hole. After the charging port 5 is connected to the charging plug 6, the second electrode of the first electrode is connected, thus forming a circuit for the charging circuit.

[0026] The tractor 1 is also equipped with an automatic connection mechanism, which is a connecting column that is slidably mounted on the rear of the tractor 1 along the longitudinal direction. An electric push rod is connected to the bottom of the connecting column. The upper end of the connecting column is provided with a cone-shaped head with the small end facing upward. A corresponding longitudinally extending insertion hole is provided at the corresponding position of the transfer vehicle. In this way, the automatic connection mechanism and the transfer vehicle can be docked by extending and retracting the electric push rod. The electric push rod is connected to the control center of the tractor 1.
