When charging is completed, the user manually opens the first chamber door 283. When the first chamber door 283 is opened, the door sensor switch 23 senses that the door is opened, and the interface device control module 201 will send a power disconnect signal to the AC circuit 2 202. After the power is disconnected, the user takes out the charging pile 3, the sensor switch 27 senses that the charging pile has been taken out, closes the first chamber door 283, and the automatic cord reel 25 automatically retracts the charging cable to complete charging.

[0050] See also Figure 8The portable charging pile 3 includes a shell 34 and a charging control device arranged inside the shell 34. At the rear end of the shell 34, there are provided a 220V charging pile input conductive plate 31 and a charging pile output collector 33 that are connected to the 220V input and output conductive plate 21 or the charging conductive plate 126. A battery life power supply is additionally provided in the charging control box. The portable charging pile 3 does not include a charging cable and a charging gun, that is, the portable charging pile 3 cancels the charging cable and charging gun of the traditional charging pile 3, and arranges the charging cable 251 and the charging gun 26 on the distributed charging interface device 2, and adds a charging pile input conductive plate 31, a charging pile output collector 33 and an IC card 32 to the portable charging pile 3. When in use, the charging pile input conductive plate 31 is connected to the 220V AC power supply, and the charging pile output collector 33 is connected to the charging cable 251 via a 220V AC contactor. Specifically, the charging pile input conductive plate 31 is connected to the 220V power input interface 211 of the 220V input and output conductive plate 21, and the charging pile output collector 33 is connected to the 220V power output interface 212. The 220V power output interface 212 is connected to the charging cable. When not in use, the charging pile input conductive plate 31 is connected to the charging conductive plate 126 of the charging dock 1, which is used to charge the power supply inside the portable charging pile 3 for battery life. Therefore, the portable charging station 3's power input and output are completed through the built-in charging station input conductive plate 31 and charging station output current collector 33. Since it does not include a charging cable or charging gun, the portable charging station's weight is effectively reduced and its ease of use is greatly improved. When the portable charging station 3 is stored in the storage box 122, it connects the charging station input conductive plate 31 with the charging conductive plate 126 on the rear side of the storage box 12 to charge the battery life power supply. The battery life power supply is used during the movement of the portable charging station 3, providing uninterrupted power to the communication module in the charging control box during shared mobility, ensuring that the 4G signal is not dropped, thus avoiding the need to wait for the portable charging station 3 to reconnect to the 4G network after being inserted into the charging interface device 2. To facilitate the removal and placement of the portable charging station 3, a handle 35 is provided on the front of the housing 34 on the side opposite the charging station input conductive plate 31, charging station output current collector 33, and IC card 32.

[0051] See also Figure 12, and the charging control device 300 of the portable charging pile 3 includes a charging pile control module 301, a display module 302, a 4G communication module 303, a battery life power module 304, a code scanning module 305, an emergency stop module 2 306, and a display light 2 307; the display module 302, the 4G communication module 303, the battery life power module 304, the code scanning module 305, the emergency stop module 2 306 and the display light 2 307 are all connected to the charging pile control module 301; the charging pile control module 301 is connected to the 220V input power and output through the charging pile input conductive plate 31 and the charging pile output collector 33 respectively. When in use, specifically: the charging pile input conductive plate 31 is connected to the 220V power input interface 211 (connected to the 220 power supply) of the 220V input and output conductive plate 21, the charging pile output collector 33 is connected to the 220V power output interface 212, and the 220V power output interface 212 is connected to the charging cable. The emergency stop module 2 306 is used to start in an emergency and cut off the power supply. The circuits for controlling charging, measuring power consumption, etc. in the charging pile control module 301, as well as the display module 302, the 4G communication module 303, the code scanning module 305, and the emergency stop module 2 306 are all prior art. The improvement of the portable charging pile 3 is that the charging cable and the charging gun are eliminated, and the charging pile input conductive plate 31, the IC card 32, the charging pile output collector 33 and the endurance power supply are added. The charging control module, the display module, the 4G communication module, etc. are not the invention points of the utility model, so they are not described in detail. When in use, the portable charging pile 3 is inserted into the distributed charging interface device 2, and docked with the 220V input and output conductive plate 21 for charging. The detailed process is as described above.

[0052] See also Figure 9 The 220V input and output conductive plate 21 is equipped with a 4mm diameter copper column 215. The charging pile input conductive plate 31 and the charging pile output collector 33 are equipped with a 4mm diameter elastic copper column 311. Its maximum current is 50A, which can meet the power demand of the 220V portable charging pile 3 (7KW). The copper column 215 on the 220V power input interface 211 and the 220V power output interface 212 is fixed. The charging pile input conductive plate 31 and the charging pile output collector 33 of the portable charging pile 3 are fixed. 3 is in an elastic and retractable state. Therefore, the elastic copper posts 311 in the charging pile input conductive plate 31 and the charging pile output collector 33 in the portable charging pile 3 are pressed against the end faces of the copper posts 215 of the 220V power input interface 211 and the 220V power output interface 212 of the distributed charging interface device 2 under the action of elastic force to achieve conductivity. After the portable charging pile 3 is installed, it can automatically connect to the charging socket (220V), and the charging pile display light 2 307 will light up. At this time, the user can take out the charging gun for use.

[0053] The above description is only illustrative and not restrictive of the present invention. The present invention aims to provide a new distributed shared charging pile system, which aims to convert the existing fixed charging pile into a portable and movable charging pile, and store it through a charging dock. At the same time, a distributed charging interface device is set near the parking space so that the user can choose the distributed charging interface device in the vacant parking space to install the portable charging pile for charging. Ordinary technicians in this field understand that without departing from the spirit and scope defined by the claims, many modifications, changes or equivalents can be made, increasing or reducing the number of portable charging piles, that is, changing the number of storage box units of the charging dock, and changing the number of distributed charging interface devices, but all will fall within the scope of protection of the present invention.
