The working principle of the invention is as follows:

firstly, inserting one side of a charging mechanism 7 into a charging hole of an automobile, opening a first top cover 3 on one side of an electric power output mechanism 2, fixedly connecting the electric power output mechanism 2 and the first top cover 3 with two sides of a first rubber rope 4 respectively, and further after opening the first top cover 3, suspending the first top cover 3 on one side of the electric power output mechanism 2 through the first rubber rope 4, further inserting one side of a plug 8 into the electric power output mechanism 2 on the front side of an electric pile 1, realizing control of the magnitude of the transmitted current through a controller 5, and further transmitting the current in the electric pile 1 into a lithium battery in the automobile through a second power transmission line 6;

then, when the driver does not unplug the car charger, the car will gradually drag the charger after starting, and then the plug 8 will gradually disengage from the inside of the power output mechanism 2, specifically, the first metal plate 803, the second metal plate 804 and the third metal plate 805 will shift outward in the inner wall of the socket 201, specifically, the conductive layer 8042 will gradually move outward from the side acting on the surface of the first conductive sheet 205, and then the first spring 206 that is deformed and compressed starts to recover to the initial state, pushes the first conductive sheet 205 to move outward, and then in the process of moving outward the second metal plate 804, one side of the conductive layer 8042 will always fit with one side of the first conductive sheet 205;

then, the conductive layer 8042 reaches the inner side of the main conductor 2031, at this time, the first spring 206 is restored to the original length, and one side of the first conductive sheet 205 is still attached to one side of the conductive layer 8042, and then the current is transferred from the inside of the electric pile to the first conductive sheet 205 through the first spring 206, and then transferred to the conductive layer 8042 through the first conductive sheet 205, and then transferred to the main conductor 2031 through the conductive layer 8042, and the specific transfer of the current in the main conductor 2031 is that the current is transferred from the second conductive sheet 20312 to the coil 20313, and then transferred from the coil 20313 to the third conductive sheet 20314, and then transferred from the third conductive sheet 20314 to the first power line 20315, and then transferred from the first power line 20315 to the buzzer 204, wherein the third metal plate 805 is connected to the second metal plate 804 in the same manner as the connection of another set of the first conductive sheet 205 and the first spring 206, and the buzzer 204 is connected to the phoenix 204 and the first spring 205 through two conductive mechanisms 203, a closed loop is formed, and the phoenix device 204 is activated to give an alarm;

then, after the first metal piece 803, the second metal piece 804 and the third metal piece 805 are completely separated from the inner wall of the socket 201, the surface of the pressing plate 20324 is not pressed, and the elastic force of the deformed second spring 20323 pushes the telescopic sub-rod 20322 to move upward, so that the telescopic sub-rod 20322 and the pressing plate 20324 synchronously move upward for a certain distance, at this time, the top end of the sub-guide rod 20325 just touches the bottom of the first spring 206, i.e., the height of the telescopic sub-rod 20322 that is raised by the sub-guide rod 20325 is set as the distance of the bottom of the first spring 206 touched by the sub-guide rod 20325, and the current inside the electric pile is transmitted to the telescopic sub-rod 20322 through the sub-guide rod 20325, and then transmitted to the second spring 20323 through the telescopic sub-rod 20322, and then transmitted to the second conductive piece 20323, and then transmitted to the coil 20312 through the second conductive piece 20312, and then transmitted to the coil 20313, and then transmitted to the third conductive piece 20314 and then to the first power line 15 through the third power line 20314, then the power is transmitted to the phoenix device 204 by the first power transmission line 20315 to form a closed loop, and then the phoenix device 204 is activated to send out a continuous alarm;

finally, the first top cover 3 is covered on one side of the power output mechanism 2, and a plug with a size completely consistent with that of the plug 8 is disposed on the inner wall of the first top cover 3, so that the plug inside the first top cover 3 gradually plugs the jack inside the socket 201, and compresses one side of the first conductive sheet 205, so as to compress the first spring 206, and the bottom surface of the plug continuously presses the extrusion plate 20324 downwards in the inward pressing process, so that the extrusion plate 20324 drives the telescopic sub-rod 20322 to press the second spring 20323 downwards, so that the sub-guide rod 20325 descends, so that the sub-guide rod 20325 is separated from the first spring 206, so as to disconnect the circuit, and the phoenix sounder 204 stops giving an alarm.

The points to be finally explained are: first, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may be a mechanical connection or an electrical connection, or a communication between two elements, and may be a direct connection, and "upper," "lower," "left," and "right" are only used to indicate a relative positional relationship, and when the absolute position of the object to be described is changed, the relative positional relationship may be changed;
