[0030] Reference Figure 1-5 , the charging pile disclosed in this embodiment includes: an input port 1 for connecting to a DC voltage, a control board 2, and a plurality of charging guns 3 for outputting a DC voltage;

[0031] The charging gun 3 connected to the device to be charged is a working charging gun, and the number of working charging guns is one or more;

[0032] When there is one working charging gun, the working charging gun is electrically connected to the input port 1 through the control board 2 ; when there are multiple working charging guns, the multiple working charging guns are electrically connected to the input port 1 in sequence through the control board 2 .

[0033] The charging pile can be used in conjunction with a traditional industrial charger. The input port 1 is used to access the DC voltage of the traditional industrial charger. The charging pile has multiple charging guns 3, which can simultaneously connect multiple devices to be charged (such as multiple electric forklifts). When the number of working charging guns is one, the working charging gun is electrically connected to the input port 1 through the control board 2; when the number of working charging guns is multiple, the multiple working charging guns are electrically connected to the input port 1 in sequence through the control board 2. The charging pile can be used in conjunction with a traditional industrial charger to realize time-sharing charging of multiple devices to be charged by one charger, first charging the first, then the second, then the third..., multiple devices to be charged can be equipped with only one charger, effectively reducing the number of chargers and greatly reducing the cost of use; the charging gun 3 is automatically switched through the control board 2, without manual intervention, and is convenient to use.

[0034] Furthermore, the control board 2 is configured to communicate with multiple charging guns 3 in a time-sharing manner, and is used to cyclically detect the status of multiple charging guns 3. When the control board 2 detects that any charging gun 3 is electrically connected to the battery of the device to be charged and the battery voltage is normal, the control board 2 is used to enable the input port 1 to supply power to the battery of the device to be charged through the corresponding charging gun 3 until the battery is fully charged.

[0035] The charging pile can be used in conjunction with a traditional industrial charger. The input port 1 is used to access the DC voltage of the traditional industrial charger. The charging pile has multiple charging guns 3, which can simultaneously connect multiple devices to be charged (such as multiple electric forklifts). The control panel 2 communicates with multiple charging guns 3 in time-sharing mode, and detects the status of multiple charging guns 3 in a cycle. When it is detected that any charging gun 3 is electrically connected to the battery of the device to be charged and the battery voltage is normal, the charging process of the charging gun 3 is turned on; when the battery is full, the charging process of the charging gun 3 is turned off, and the status of other charging guns 3 is detected in a cycle. The charging pile can be used in conjunction with a traditional industrial charger to realize time-sharing charging of multiple devices to be charged by one charger, first charging the first, then the second, then the third..., multiple devices to be charged can be equipped with only one charger, which effectively reduces the number of chargers and greatly reduces the cost of use; the charging gun 3 is automatically switched by the control panel 2, without manual intervention, and is convenient to use.

[0036] Furthermore, the charging pile also includes multiple groups of switch components 4, which are connected between the control board 2 and the charging gun 3. The switch components 4 are used to connect the control board 2 and the charging gun 3 when the control board 2 detects that the corresponding charging gun 3 is electrically connected to the battery of the device to be charged and the battery voltage is normal.

[0037] The switch assembly 4 includes two relays 41 , one of the relays 41 is used to connect to the positive pole of the power supply, and the other relay 41 is used to connect to the negative pole of the power supply.

[0038] Furthermore, the control board 2 is integrated with a communication detection module, a cyclic switching module and a reverse connection protection module; the communication detection module is used to communicate with multiple charging guns 3 in a time-sharing manner and cyclically detect the status of multiple charging guns 3; the cyclic switching module is used to control the switch component 4 to open or close the electrical connection between the charging gun 3 and the input port 1; the reverse connection protection module is used to detect whether the polarity connection of the charging gun 3 is correct.

[0039] The control board 2 not only implements basic communication detection and cyclic switching functions, but also integrates a reverse connection protection module to improve the stability and safety of the system. These functions ensure that the charging pile can efficiently and accurately manage multiple charging guns 3 to prevent incorrect connections.

[0040] Furthermore, the charging pile also includes a box body 5 and a mounting frame 6 , the control board 2 and the switch assembly 4 are both arranged in the box body 5 , and the box body 5 is fixed on the mounting frame 6 .

[0041] By arranging the control board 2 and the switch assembly 4 in a structured box 5 and fixing the box 5 on the mounting frame 6, the stability and durability of the charging pile are increased. This design also facilitates the installation and maintenance of the charging pile.

When the charging gun 3 is not in use, it can be placed on the hooks 621 to facilitate the storage of the charging gun 3, and the box body 5 is fixed on the support plate 62.

[0043] Among them, the box body 5 includes a front panel 51, a back panel 52, two side panels 53, a top panel 54 and a bottom panel 55; the front panel 51 is provided with a touch display screen 511, a start button 512 and a stop button 513; the back panel 52 is arranged in contact with the support plate 62; the two side panels 53 are fixed to the support plate 62 by angle steels 56, and the two side panels 53 are provided with multiple heat dissipation mesh holes 530.

[0044] The design of the box 5 takes into account the needs of user interaction and device heat dissipation, including a touch display screen 511, a start button 512, a stop button 513, and a heat dissipation mesh 530. These designs improve the user-friendliness and long-term reliability of the charging pile.

[0045] A charging system includes a charger 7 and the above-mentioned charging pile, wherein the charger 7 is electrically connected to the charging pile, and the charger 7 is used to convert an input AC voltage into a DC voltage and transmit it to the charging pile.
