[0019] The utility model discloses a DC charger. The specific embodiments of the utility model are further described below in conjunction with preferred embodiments.

[0020] In the embodiments of the present invention, those skilled in the art note that the power module and the like involved in the present invention may be regarded as prior art.

[0021] Preferred embodiments.

[0022] like Figure 1-4 As shown, the utility model discloses a DC charger, including a box module 100 and a driving charging module 200, wherein the driving charging module 200 is installed in the box module 100, wherein:

[0023] The box module 100 includes a chassis 110, a first connecting frame 120 and a second connecting frame 130, wherein the first connecting frame 120 and the second connecting frame 130 are respectively fixedly mounted on both sides of the bottom of the chassis 110; a control display component 111 (for card swiping, start and close operations) is provided on the front of the chassis 110, a ventilation hole area 112 and a charging port area 113 are provided on the first side of the chassis 110, and the ventilation hole area 112 is located above the charging port area 113, a first cooling fan 114 and a second cooling fan 115 are provided on the second side of the chassis 110, and a signal transmission component 116 is provided on the top surface of the chassis 110;

[0024] The driving charging module 200 includes a driving cylinder 210, a driving frame 220, a charging socket mounting plate 230, a charging socket 240, a first connecting rod 250, a second connecting rod 260, a third connecting rod 270 and a fourth connecting rod 280. The driving frame 220 is provided with a bottom plate 221, a vertical plate 222, a first reinforcing plate 223 and a second reinforcing plate 224. The bottom plate 221 is connected to the driving end of the driving cylinder 210 and the vertical plate 222 is installed on the bottom plate 221. The first reinforcing plate 223 and the second reinforcing plate 224 are both installed between the bottom plate 221 and the vertical plate 222. The first ends of the third connecting rod 270 and the fourth connecting rod 280 are both fixedly mounted on the charging socket mounting plate 230, and the second ends of the first connecting rod 250, the second connecting rod 260, the third connecting rod 270 and the fourth connecting rod 280 are all located on the vertical plate 222 (located at one end of the vertical plate and can move relatively), the first connecting rod 250 is sleeved with a first buffer spring 251, the second connecting rod 260 is sleeved with a second buffer spring 261, the third connecting rod 270 is sleeved with a third buffer spring 271, the fourth connecting rod 280 is sleeved with a fourth buffer spring 281, and the charging socket 240 is fixedly mounted on the charging socket mounting plate 230.

[0025] Specifically, the charging socket 240 is provided with a first slot portion 251 and a second slot portion 242 . The first slot portion 241 is installed with a first connection terminal 243 , and the second slot portion 242 is installed with a second connection terminal 244 .
