[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0023] First embodiment:

[0024] like Figure 1-4 As shown, the new energy vehicle charging pile for preventing electric shock provided by the utility model includes: a waterproof sleeve 4, the waterproof sleeve 4 includes: a rubber sleeve 41, a multi-layer wrinkled rubber 43 is provided on the outer surface of the rubber sleeve 41, a locking slide 42 is provided at the top and bottom of the rubber sleeve 41, and a positioning ring 44 is provided at the front end of the rubber sleeve 41. The waterproof sleeve 4 is provided on the external charging pile body, the waterproof sleeve 4 is in contact with the front end of the charging gun body 1, and a locking buckle 2 is provided on the top of the charging gun body 1. The charging gun body 1 is fixedly connected to the locking buckle 2, and the front end of the locking buckle 2 cooperates with the locking slide 42 on the rubber sleeve 41. A wiring harness interface 3 is provided at the rear end of the charging gun body 1, and the wiring harness interface 3 is connected to the wiring harness on the external charging pile.

[0025] By setting a waterproof sleeve 4 in front of the charging gun body 1, in rainy weather, water droplets between the external charging pile and the charging gun body 1 will adhere to the waterproof sleeve 4. By unlocking the locking buckle 2 and removing the charging gun body 1, the waterproof sleeve 4 will protect the charging gun body 1 and will not contaminate the charging gun body 1.

[0026] Second embodiment:

[0027] like Figure 4 As shown, the positioning ring 44 includes: a fixed ring 441 and telescopic rods 442 . There are four telescopic rods 442 , which are equidistantly distributed on the fixed ring 441 circumferentially. The telescopic rods 442 are fixedly connected to the fixed ring 441 .

[0028] By setting up telescopic rods 442 equidistantly distributed around the circumference in the rubber sleeve 41 , the locking buckle 2 can be kept sliding along the locking slot 42 when the rubber sleeve 41 is in contact with the charging gun body 1 , thereby fixing and positioning the charging gun body 1 .

[0029] Third embodiment:

[0030] like Figure 3As shown, a connection groove is provided at the front end of the rubber sleeve 41 corresponding to the telescopic rod 442 , which cooperates with the telescopic rod 442 . The bottom of the telescopic rod 442 is fixedly connected to the bottom of the rubber sleeve 41 , and the fixing ring 441 is installed on the external charging pile.

[0031] By providing a fixing ring 441 installed on an external charging pile, existing equipment can be retrofitted. When the waterproof sleeve 4 fails or wears out, the waterproof sleeve 4 can be quickly replaced by disassembling and assembling the fixing ring 441.

[0032] Working principle: In actual use, when the charging gun body 1 is charged and placed on an external charging pile, the front end of the charging gun body 1 compresses the waterproof sleeve 4, and the rubber sleeve 41 is compressed to produce a wrinkled rubber 43. At the same time, the telescopic rod 442 contracts inward under the limiting action of the fixed ring 441. Due to the limiting effect of the telescopic rod 442 on the rubber sleeve 41, it will not rotate during the contraction process. The locking buckle 2 slides inward along the locking groove 42 on the waterproof sleeve 4 and completes the engagement. When the charging gun body 1 is pulled out from the external charging pile, its working process is opposite to the above process.

[0033] The above embodiment is only one of the preferred implementation methods of the present invention and should not be used to limit the scope of protection of the present invention. Any changes or modifications that have no substantive meaning made to the main design concept and spirit of the present invention, as long as the technical problems they solve are still consistent with the present invention, should be included in the scope of protection of the present invention.
