Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 6, the charging-pack cable winding machine according to the present embodiment includes a housing 1, a cable 2, a winding shaft 10, a reduction motor 3, an input gear 32, a third roller 33, a fourth roller 34, and a charging gun 22, wherein the charging gun 22 is connected to the cable 2, and an inner end of the cable 2 is connected to the winding shaft 10. The winding shaft 10 is rotatably provided in the middle of the housing.

The casing 1 is assembled by the front cover 12 and the base 11, the inner cavity of the casing 1 comprises a first cavity 81 for accommodating the cable 2 and a second cavity 82 for accommodating the charging gun 22, and the first cavity 81 is positioned at one side of the second cavity 82; the casing 1 has a lower port 13 for charging the charging gun 22 to enter and exit, and an annular support 21 for orderly winding the cable 2 is arranged in the first cavity 81.

As shown in fig. 4, 5 and 6, the reduction motor 3 is provided at the power output end in the housing 1 and has an output gear 31, the output gear 31 is coaxially provided with a first roller 311, the first roller 311 is located at the front end of the first cavity 81 and has a first annular groove 312 at the outer periphery.
