[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] For example, see the attached Figure 1The utility model provides an unmanned automatic charging system for container trucks, including a charging pile 1. A charging control module is provided in the charging pile 1. The charging control module is a prior art and is similar in structure to the charging control module of a common charging pile 1 on the market. It can provide functions such as power output and automatic charging control. An inspection port 11 is provided on the upper part of the charging pile 1. An inspection compartment protective cover 3 is provided above the inspection port 11. One end of the inspection compartment protective cover 3 is rotatably connected to the charging pile 1. The inspection compartment protective cover 3 is connected to the charging pile 1 through a protective cover driving cylinder 4. The protective cover driving cylinder 4 is used to drive the inspection compartment protective cover 3 to rotate open or close. Close it to facilitate later inspection and maintenance. A charging port is arranged on the side of the charging pile 1. A charging gun connection shell 5 is arranged at the position of the charging port. The charging gun connection shell 5 is connected to the charging pile 1 through a linear drive device. A charging gun assembly is arranged on the side of the charging gun connection shell 5 facing the outside of the charging pile 1. The charging gun assembly includes a connecting wire group 6 and a charging connector 8. The charging connector 8 is configured with a national standard charging socket that matches the unmanned container truck charging port. At the same time, the unmanned container truck charging port and the charging connector 8 are respectively provided with matching interface sensors, which can accurately sense the positions of the two so as to facilitate automatic docking of the two. Refer to the attached Figure 2 One end of the connecting wire group 6 is electrically connected to the charging connector 8, and the other end passes through the charging port and is electrically connected to the charging control module. The connecting wire group 6 and the charging gun connecting shell 5 are driven and connected by the angle adjustment swing arm 7. The angle adjustment swing arm 7 includes a cross-arranged connecting arm 71 and an angle adjustment push rod 72. The two ends of the connecting arm 71 are respectively rotatably connected to the connecting wire group 6 and the charging gun connecting shell 5, and the two ends of the angle adjustment push rod 72 are also respectively rotatably connected to the connecting wire group 6 and the charging gun connecting shell 5. Such a cross-arm-like structure can change the insertion angle of the charging connector 8 by driving the angle adjustment push rod 72, which can adapt to more complex usage conditions. At the same time, the charging gun connecting shell 5 can drive the charging gun assembly to extend out of the charging port or retract into the charging pile 1 under the drive of the linear drive device, so that the charging connector 8 can be effectively protected during non-charging time.

[0019] At the same time, in some of the embodiments, a fixed base 2 is fixedly arranged under the charging pile 1, and a lifting mechanism is fixedly arranged on the side of the fixed base 2 facing the charging pile 1. The lifting mechanism is connected to the charging pile 1 and is used to drive the charging pile 1 to rise and fall, so that the height of the charging gun assembly can be fine-tuned, which can be more flexible during on-site installation.

[0020] The working principle of this embodiment is as follows:

[0021] The unmanned container truck automatic charging system of the present embodiment is used in combination with the unmanned container truck. The unmanned container truck automatic charging system and the unmanned container truck realize real-time information interconnection through the wireless modules they are equipped with. The unmanned container truck can send the position, power level and other information to the designated unmanned container truck automatic charging system in real time. When the unmanned container truck needs to be charged, it will run to the designated position of the unmanned container truck automatic charging system. At this time, the charging gun connection shell 5 of the unmanned container truck automatic charging system drives the charging gun assembly to extend out of the charging port under the drive of the linear drive device, and at the same time adjusts the angle of the charging connector 8 according to the position of the unmanned container truck, and finally inserts the charging connector 8 into the charging port of the unmanned container truck. After charging is completed, the charging gun connection shell 5 drives the charging gun assembly to retract into the charging pile 1 under the drive of the linear drive device.
