[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, the utility model provides a new energy charging pile waterproof plug, including a charging pile body 1 and a charging plug 2, and also includes:

[0022] A waterproof mechanism, which is arranged on the charging pile body 1 and is used to prevent rainwater from penetrating into the interior of the charging pile;

[0023] Among them, the waterproof mechanism includes a fixed rod 3, which is arranged inside the charging pile body 1. The outer surface of the fixed rod 3 is sleeved with a movable frame 4 and a first spring 5. The inner side of the movable frame 4 is bonded with a rubber pad 6. A protective shell 7 is installed on one side of the charging pile body 1. The outer side of the protective shell 7 is hinged with a limiting member 8 through a torsion spring. A cavity 9 is opened inside the charging pile body 1, and the second spring 10 and a pressure plate 11 are sleeved inside the cavity 9.

[0024] When the charging plug 2 is inserted into the interior of the charging pile body 1, the charging plug 2 will squeeze the pressure plate 11. At this time, the chamfer of the pressure plate 11 will squeeze the movable frame 4, thereby driving the movable frame 4 to move along the outer surface of the fixed rod 3, so that the rubber pad 6 can be driven by the movable frame 4 to squeeze the charging plug 2. At the same time, through the cooperation between the limit member 8 and the protective shell 7, the torsion spring will drive the limit member 8 to rotate and through the cooperation between the limit member 8 and the movable frame 4, the movable frame 4 is limited, and then the gap between the charging plug 2 and the charging pile body 1 can be sealed through the rubber pad 6.

[0025] Among them, the first spring 5 is elastically supported between the charging pile body 1 and the movable frame 4.

[0026] Through the design of the first spring 5, the movable frame 4 has good elastic reset performance. At this time, since the first spring 5 is in a compressed state, an elastic force is applied to the movable frame 4, so that the movable frame 4 can be driven by the first spring 5 to move along the outer surface of the fixed rod 3, so that the rubber pad 6 will be separated from the charging plug 2.

[0027] The rubber pad 6 is in compression contact with the charging plug 2 .

[0028] Through the cooperation between the rubber pad 6 and the charging plug 2 , when the rubber pad 6 squeezes the charging plug 2 , the rubber pad 6 will fill the gap formed between the charging pile body 1 and the charging plug 2 , thereby preventing rainwater from penetrating into the interior of the charging pile body 1 .

[0029] The movable frame 4 is sleeved with the protective shell 7 , and the limiting member 8 is movably engaged with the movable frame 4 .

[0030] The cooperation between the movable frame 4 and the protective shell 7 can block rainwater, and the cooperation between the limiting member 8 and the movable frame 4 can limit the movable frame 4.

[0031] One side of the pressing plate 11 is provided with a chamfer, and the pressing plate 11 is in compression contact with the movable frame 4 .

[0032] Through the cooperation between the pressing plate 11 and the movable frame 4 , when the chamfer of the pressing plate 11 presses the movable frame 4 , the movable frame 4 will be driven to move along the outer surface of the fixing rod 3 , thereby driving the rubber pad 6 to press the charging plug 2 .

[0033] The second spring 10 is elastically supported between the charging pile body 1 and the pressure plate 11 .

[0034] Through the design of the second spring 10, the pressure plate 11 has good elastic reset performance. At this time, since the second spring 10 is in a compressed state, an elastic force will be applied to the pressure plate 11, thereby driving the pressure plate 11 to release the squeeze on the movable frame 4. At this time, the elastic force of the first spring 5 will drive the movable frame 4 to reset.

[0035] The working principle and use process of this utility model:

[0036] When the charging plug 2 is inserted into the charging pile body 1, the pressure plate 11 will be squeezed. At this time, the chamfer of the pressure plate 11 will squeeze the movable frame 4, thereby driving the movable frame 4 to move along the outer surface of the fixed rod 3, so that the rubber pad 6 can be driven by the movable frame 4 to squeeze the charging plug 2. At the same time, through the cooperation between the limit member 8 and the protective shell 7, the torsion spring will drive the limit member 8 to rotate and through the cooperation between the limit member 8 and the movable frame 4, the movable frame 4 is limited, and then the gap between the charging plug 2 and the charging pile body 1 can be sealed through the rubber pad 6.
