[0022] Example 1; as Figures 1-2 As shown, this utility model proposes an anti-drag charging pile for new energy vehicles, including a charging pile body 1 and a charging gun 2 connected to the charging pile body 1 via a wire. A handheld part 6 is provided at the tail of the charging gun 2, and a buckle 4 is provided at the charging end of the charging gun 2 to engage with the vehicle body. A pressing block 5 is provided on the charging gun 2 to change the state of the buckle 4. The pressing block 5 is located at the front end of the handheld part 6. Pressing the pressing block 5 releases the buckle 4 from the vehicle's charging port. The pressing block 5 and the buckle 4 are connected by mechanical components such as a linkage or gear. When the user presses the pressing block 5, the linkage or gear begins to move, and the pressing force is transmitted to the buckle 4 through the linkage or gear, causing the buckle 4 to rotate or move, thereby releasing it from the slot of the vehicle's charging port and unlocking it. The buckle 4 is also connected to a spring. When the pressing block 5 is released, the spring pushes the latch back to the locked position to reset. During the pressing process, the user will feel a certain resistance or hear a slight sound to confirm that the latch 4 has been released. The linkage between the pressing block 5 and the latch 4 is a conventional technology, and most existing charging guns on the market include this locking structure. The charging pile body 1 and the charging gun 2 work together through physical connection and communication protocol to ensure the safety, efficiency and intelligence of the charging process. This part is a conventional charging pile structure, which will not be described in detail in this application. The charging gun 2 is equipped with a trigger mechanism for automatically pressing down the pressing block 5. When there is no one around the charging gun 2 and its moving speed reaches the set value, the trigger mechanism is activated, pressing down the pressing block 5 to release the latch 4 from the vehicle charging port, making it easy for the charging gun 2 to detach from the moving vehicle charging port.

[0023] Furthermore, a box 7 is provided at the bottom of the charging gun 2. The box 7 is located in front of the handheld part 6. The box 7 is made of plastic. The trigger mechanism is located on the box 7. A rear sealing plate 10 is provided on the side of the box 7 facing the handheld part 6. Opening the rear sealing plate 10 allows for the inspection and maintenance of the trigger mechanism.

[0024] Embodiment two; as Figures 2-4 Compared with embodiment one, the embodiment details the structure of the trigger mechanism.

[0025] The trigger mechanism includes a sensing component and an execution component. The sensing component is used to sense whether there is a human body around the charging gun 2, and the execution component is used to complete the pressing action of the pressing block 5.

[0026] The sensing component includes a human body sensing sensor 8 and a speed detection sensor 11 arranged on the box body 7. A control system 12 is arranged in the box body 7, and the control system 12 is in data transmission connection with the human body sensing sensor 8 and the speed detection sensor 11. The human body sensing sensor 8 is an infrared sensor, a microwave sensor or an ultrasonic sensor. The most commonly used is an infrared sensor. The infrared light is emitted and the reflected signal is detected to determine whether there is an object. When a person approaches the charging gun, the infrared signal reflected by the human body will be detected by the sensor, thereby triggering the corresponding action. The speed detection sensor 11 is an acceleration sensor or a gyroscope. The most commonly used is an acceleration sensor. The acceleration of the charging gun 2 is detected to determine its speed. When the charging gun 2 moves with the vehicle, the acceleration sensor will detect the acceleration signal and calculate the speed by integration. The control system 12 includes a microcontroller, a power module and a signal processing module. The microcontroller is responsible for receiving the signals of the human body sensing sensor 8 and the speed detection sensor 11, performing data processing and logical judgment. Common microcontrollers include Arduino, Raspberry Pi, STM32, etc. The power module provides stable power supply for the control system, the human body sensing sensor 8 and the speed detection sensor 11 to ensure normal work. The signal processing module amplifies and filters the signals of the human body sensing sensor 8 and the speed detection sensor 11 to improve the accuracy of the signals. Common signal processing modules include operational amplifiers, filters, etc. The detection range of the human body sensing sensor 8 is within one meter of the space around the charging gun 2. When the human body sensing sensor 8 does not detect a human body and the speed detection sensor 11 detects that the moving speed of the charging gun 2 is not less than 5 kilometers per hour, the execution component is started. The speed of the vehicle when starting is usually low, generally between 5-10 kilometers per hour. In order to ensure that the system can timely detect the situation that the vehicle starts without pulling the gun, the speed threshold is set in a lower range, for example, 5 kilometers per hour. In this way, the system can trigger an alarm or automatically disconnect the charging gun when the vehicle just starts to move, thereby avoiding potential safety risks. In order to start the execution component, the control system 12 is also provided with an execution component driving module to convert the control signal of the microcontroller into current or voltage to drive the execution component to work. Common driving modules include motor driving boards, PWM controllers, etc.

[0027] The execution assembly comprises a U-shaped pressing plate 13 arranged on the top of the box body 7 in a sliding manner along the vertical direction, and an electric push rod 16 arranged in the box body 7 and driving the U-shaped pressing plate 13 to move up and down; the U-shaped groove of the U-shaped pressing plate 13 is open downward, both ends of the bottom of the U-shaped pressing plate 13 are slidingly inserted into the box body 7, the top of the U-shaped pressing plate 13 is pressed on the pressing block 5, and the top telescopic end of the electric push rod 16 is connected with the bottom of the U-shaped pressing plate 13; the control system 12 is in control connection with the electric push rod 16; specifically, two avoiding holes are arranged on the top of the box body 7, both ends of the U-shaped pressing plate 13 are matched to pass through the two avoiding holes, flat plates 14 are arranged on the bottom of both sides of the U-shaped pressing plate 13, the top telescopic end of the electric push rod 16 is connected with the bottom of the flat plate 14, and in order to improve the moving stability of the U-shaped pressing plate 13, a guide hole is arranged on the flat plate 14, and a guide rod 15 is arranged in the box body 7 and matched to pass through the guide hole.

[0028] Further, a reset button 9 is arranged on the box body 7 and electrically connected with the control system 12, the reset button 9 is pressed, the electric push rod 16 is extended upward to complete the reset, and the pressing on the pressing block 5 is released.

[0029] Further, a control system external wire 17 is arranged on the control system 12, the control system external wire 17 and the wire of the charging gun 2 are wrapped by the cable sleeve 3, the control system external wire 17 and the wire of the charging gun 2 are wrapped in the cable sleeve 3, the whole is more beautiful, and the control system external wire 17 is connected with the mains to supply power for the control system 12.

[0030] Embodiment three; compared with embodiment two, the electrical connection structure is specifically introduced in the embodiment.

[0032] In summary, when the car is started without pulling out the gun, the car drives the charging gun 2 to move at a certain speed, and at this time there is no human body around the charging gun 2, the execution action is triggered, the control system 12 controls the electric push rod 16 to retract to drive the U-shaped pressing plate 13 to move downward to make the pressing block 5 move downward, the clamping connection of the buckle 4 and the car charging port is released, under the tension of the cable sleeve 3, the charging gun 2 is separated from the charging port, even if the car is started and driven away without pulling out the gun, the charging gun 2 and the charging pile body 1 will not be damaged, thereby achieving the purpose of preventing dragging. In addition, during the charging operation of the operator holding the charging gun 2 and moving, since the human body sensing sensor 8 detects that there is a human body around, even if the speed detection sensor 11 detects that the moving speed of the charging gun 2 reaches the set speed, the execution assembly will not be triggered at this time, and the normal use of the charging gun 2 is ensured.
