[0037] like Figures 1 to 7 As shown in the figure, an embodiment of this utility model provides a three-door charging stack main cabinet, comprising:

[0038] Cabinet 100;

[0039] Mounting rack 200 is disposed inside the cabinet 100, and the mounting rack 200 includes a charging module compartment 210 and a scheduling module compartment 220;

[0040] The charging module compartment 210 holds N charging modules 300, each charging module 300 including M charging modules 310, and each of the M charging modules 310 is connected to M DC power output terminals 320 in a one-to-one correspondence; N and M are both positive integers.

[0041] The scheduling module compartment 220 houses a control circuit board 400 and N sets of DC scheduling modules 500 connected to the control circuit board 400. Each of the N sets of DC scheduling modules 500 corresponds to one of the N charging modules 300. Each DC scheduling module 500 includes multiple DC contactors 510, which are connected between the power supply lines of the corresponding M charging modules 310 and the M DC power output terminals 320.

[0042] The control circuit board 400 is used to control the on / off state of each of the DC contactors 510.

[0043] In the embodiments provided by this utility model, the mounting bracket 200 provides installation space and support for each unit structure. A corresponding number of charging modules 310 are configured according to the quantity requirements of the DC power output terminals 320. There can be one or more charging modules 300. When there are multiple charging modules 300, a corresponding number of DC dispatching modules 500 are configured. By controlling the on / off state of each DC contactor 510, one or more charging modules 310 are dispatched to the DC power output terminals 320, enabling flexible dispatching of each charging module 310. By dispatching the corresponding charging modules 310 to the DC power output terminals 320, module idleness is reduced, and power utilization is improved. Since multiple charging modules 310 can be dispatched to power one DC power output terminal 320, power superposition is achieved, maximizing the power requirements of the DC power output terminals 320 and thus improving charging efficiency. Therefore, while meeting the quantity requirements of the DC power output terminals 320, the number of charging modules 310 can be reduced, thereby reducing the size and floor space of the main cabinet.

[0044] In some improved embodiments, the N groups of DC dispatch modules 500 are bridged via bridging copper busbars 520.

[0045] By bridging N DC dispatch modules 500, the charging modules 310 in each charging module 300 can be dispatched to achieve higher charging power.

[0046] In some improved embodiments, the charging module compartment 210 is located above the scheduling module compartment 220, and the charging module compartment 210 includes N layers of charging module sub-compartments 211, with one charging module 300 placed in each layer of the charging module sub-compartments 211.

[0047] When there are multiple charging modules 300, a corresponding number of charging module compartments 211 are configured, and each charging module compartment 211 holds one charging module 300. In this embodiment, two charging modules 300 and two DC scheduling modules 500 are set up. Two charging modules 300 are placed in the two-layer charging module compartments 211, and two DC scheduling modules 500 are placed in the scheduling module compartment 220.

[0048] In some improved embodiments, the cabinet 100 includes a front door 110, the front door 110 having an air inlet mesh 111, the front door 110 being provided with a dustproof filter cotton 112, the dustproof filter cotton 112 being located inside the cabinet 100.

[0049] Air is allowed into the cabinet 100 through the air inlet mesh 111, and the incoming air is filtered by the dust filter cotton 112. The air inlet mesh 111 and the dust filter cotton 112 work together to provide clean air for the inside of the cabinet 100.

[0050] In some improved embodiments, the front door 110 is provided with a light-transmitting panel 113 and an indicator light circuit board 114 disposed inside the light-transmitting panel 113, the indicator light circuit board 114 being used to display the corresponding light of the indicator signal.

[0051] The light displayed on the indicator circuit board 114 is transmitted through the light-transmitting plate 113, so as to provide the user with corresponding indication signals through the light.

[0052] In some improved embodiments, the cabinet 100 includes a rear door 120, the rear door 120 being provided with an air guide ring 121 and a centrifugal fan 122 disposed in the air guide ring 121; the centrifugal fan 122 is used to extract air entering the cabinet 100 from the air inlet mesh 111 through the air guide ring 121.

[0053] The mounting frame 200 and the front door 110 form an air intake chamber, and the mounting frame 200 and the rear door 120 form a heat dissipation air duct chamber. After the air enters the cabinet 100 through the air intake mesh 111, it forms an airflow under the action of the centrifugal fan 122 and is drawn out from the air guide ring 121, thereby dissipating heat and ventilating the inside of the cabinet 100, providing a good temperature and humidity environment, and extending the service life of the charging pile.

[0054] The number of cooling centrifugal fan modules can be one or more. In this embodiment, two cooling centrifugal fan modules are set to exhaust air from the charging module compartment 210 and the scheduling module compartment 220, respectively.

[0055] In some improved embodiments, the cabinet 100 includes a side door 130, and the mounting bracket 200 is provided with N AC power distribution modules 600 on the side near the side door 130, and the N AC power distribution modules 600 correspond one-to-one with the N charging modules 300.

[0056] The AC power distribution module 600 includes an AC circuit breaker 610 and an AC contactor 620. The input terminal of the AC circuit breaker 610 is connected to the AC power supply terminal 700, and the output terminal of the AC circuit breaker 610 is connected to the input terminal of the AC contactor 620. The output terminals of the AC contactor 620 are respectively connected to each charging module 310 in the corresponding charging module 300.

[0057] The area between the mounting frame 200 and the side door 130 is divided into an AC power distribution compartment. N AC power distribution modules 600 are installed in the AC power distribution compartment. AC power is connected through the AC power distribution modules 600 and converted into DC power suitable for the charging module 300. In this embodiment, the current flow of the charging pile is as follows: AC power supply terminal 700 → AC circuit breaker 610 → AC contactor 620 → charging module 310 → DC contactor 510 → DC power output terminal 320.

[0058] In some improved embodiments, the mounting bracket 200 is further provided with a surge protector, an auxiliary power supply, and a terminal block on the side near the side door 130.

[0059] In some improved embodiments, the side door 130 has a built-in display screen 131 and an emergency stop button 132.

[0060] By incorporating a display screen 131 and an emergency stop button 132 on the side door 130, users can easily understand the working status of the charging pile and, in an emergency, stop the operation of the charging pile to protect the equipment safety.

[0061] The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but this does not limit the scope of the present invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and spirit of the present invention should be within the scope of the present invention.
