Embodiment 1
[0033] A safe charging interface for an electric vehicle charging pile, such as figure 1 As shown, it includes a male port 11 on the charging gun 1 and a female port 21 on the charging device; an adjustment pin 12 is provided outside the male port 11 of the charging gun 1; the adjustment pin 12 protrudes along the insertion direction of the male port 11, protruding from the surface of the male port 11;
[0034] Such as figure 2 As shown, a sealed chamber 22 is arranged in the charging port of the automobile, and the sealed chamber 22 is a double-chamber structure, the female port 21 is located in the first chamber 221, and the adjusting seesaw 25 is arranged in the second chamber 222; a panel 23 is arranged outside the sealed chamber 22, and the panel The charging hole 231 and the adjusting hole 232 corresponding to the position of the male port 11 on the charging gun 1 and the position of the adjusting pin 12 are respectively set on the 23; a retractable barrier is set in t...
Embodiment 2
[0042] This embodiment makes the following improvements on the basis of the previous example:
[0043] A guide rail for sliding is provided on the side of the isolation baffle 24 that is in contact with the slot 233 . After the guide rail is installed, the isolation baffle 24 will move more smoothly between the slots 233 , so that it is convenient for the operator to insert and remove the interface.
Embodiment 3
[0045] This embodiment makes the following improvements on the basis of the previous example:
[0046] Both sides of the isolating baffle 24 along the telescopic direction are connected to the inner wall of the sealing chamber 22 through the first elastic body 241. When the first elastic body 24 is in a free state, the isolating baffle 24 is located directly above the female port 21, and the seesaw 25 is adjusted. When it is at the maximum lifting height, the pull rope 26 pulls the isolation baffle 24 to completely move away from the top of the female port 21 .
[0047] The first elastic body 241 at both ends of the isolation baffle 24 is mainly used to reset the isolation baffle 24 , the isolation baffle 24 is removed in the plugged state, and the isolation baffle 24 immediately resumes the sealing and isolation function in the unplugged state.
