[0029] In addition, the described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of this utility model.

[0030] As Figures 1 to 7 shown, a maze-type air duct double-gun DC charger provided by an embodiment of this utility model includes: a cabinet body 100, and a front door 110, a rear door 120, a left door 130 and a right door 140 movably arranged on the cabinet body 100;

[0031] A charging module bin 200 is arranged inside the cabinet body 100. The area between the charging module bin 200 and the front door 110 is divided into a power distribution function bin 300, and the area between the charging module bin 200 and the rear door 120 is divided into an air inlet bin 400; A plurality of groups of charging modules are installed in the charging module bin 200, and there are gaps between the plurality of groups of charging modules;

[0032] An air inlet 121 is arranged on the rear door 120, an air outlet 141 is arranged on the right door 140, and a cooling fan 500 communicated with the air outlet 141 is installed on the inner side of the right door 140; The charging module bin 200 is located between the left door 130 and the cooling fan 500;

[0033] When the cooling fan 500 operates, an air duct is formed inside the cabinet body 100 that sequentially passes through the air inlet 121, the air inlet bin 400, the charging module bin 200, the cooling fan 500 to the air outlet 141.

[0034] In this embodiment, the interior of the cabinet body 100 is divided into three areas: front, middle, and rear. The front compartment near the front door 110 is the power distribution function compartment 300, the middle compartment is the charging module compartment 200, and the rear compartment is the air intake compartment 400.

[0035] In this embodiment, by partitioning the functions of the cabinet body 100, cold air enters the air intake compartment 400 from the rear door 120 of the cabinet body 100, and then turns 90 degrees through the air duct and enters the charging module compartment 200. There are gaps between multiple groups of charging modules installed in the charging module compartment 200, which can ensure air circulation. By forming a maze space from the air inlet 121 to the charging module compartment 200, the noise generated by the charging modules in the charging module compartment 200 is difficult to penetrate the maze and spread outside the cabinet body 100, effectively reducing the noise of the charger. When the cooling fan 500 is turned on, an air duct as shown by the arrow in Figure 2 is formed, and the heat energy generated by the charging modules is discharged from the inside of the charger through the cooling fan 500.

[0036] In some embodiments, the power distribution function compartment 300 is sequentially provided with a DC power distribution function area 310, a main control function area 320, and an AC power distribution function area 330 from top to bottom. A DC power distribution module is installed in the DC power distribution function area 310, a main control module is installed in the main control function area 320, and an AC power distribution module is installed in the AC power distribution function area 330.

[0037] In this embodiment, the upper, middle, and lower regions of the power distribution function compartment 300 are respectively the DC power distribution function area 310 at the upper end, the main control function area 320 in the middle, and the AC power distribution function area 330 at the lower end; the AC power distribution function area 330 at the lower end is the access point for user input power, and the DC power distribution function area 310 at the upper end is connected to the DC gun line after passing through electrical components. The overall AC and DC wiring is separated and does not cross. The AC and DC function areas of the power distribution compartment are reasonably divided, which simplifies the electrical connection.

[0038] In some embodiments, a touch liquid crystal screen 111 and a card reader 112 are installed on the front door 110, and the main control module is respectively communicatively connected to the touch liquid crystal screen 111 and the card reader 112, and the main control module is used for information interaction processing with the touch liquid crystal screen 111 and the card reader 112.

[0039] In this embodiment, by installing a touch liquid crystal screen 111 and a card reader 112 on the front door 110, the human-machine interaction operation function of the charger is realized.

[0040] In some embodiments, an emergency stop button 131 and a first gun plug seat 132 are installed on the outer side of the left door 130.

[0041] In this embodiment, an emergency stop button 131 and a first gun plug seat 132 are installed outside the left door 130. The emergency stop button 131 is used to stop the operation of the charger in case of emergency. The emergency stop button 131 is set outside the left door 130, which is convenient for users to quickly press the emergency stop button 131 to take protective measures in case of emergency. The first gun plug seat 132 is used to place the charging gun in place.

[0042] In some embodiments, a second gun plug seat 142 is installed outside the right door 140.

[0043] In this embodiment, by installing the second gun plug seat 142 outside the right door 140, it is convenient to place the charging gun in place.

[0044] In some embodiments, a gun wire storage bin 600 for storing the gun wire is installed at the top of the charger, and the gun wire storage bin 600 can expand and contract along the left and right sides of the charger.

[0045] When the existing charger is in use, the gun wire often drags on the ground, and a more reasonable and beautiful solution to the on-site use problem is needed. In this embodiment, by installing the gun wire storage bin 600 on both sides of the upper end of the charger, the storage management of the gun wire is realized.

[0046] The preferred embodiments of the embodiments of the present invention have been described above with reference to the accompanying drawings. However, this does not limit the scope of the rights of the embodiments of the present invention. Any modifications, equivalent replacements, and improvements made by those skilled in the art without departing from the scope and essence of the embodiments of the present invention shall fall within the scope of the rights of the embodiments of the present invention.
