1. the device comprises a shell, 2, an upper cover, 3, a cable, 31, a charging gun, 4, a guide rail, 5, a supporting plate, 51, a fixed pulley, 6, a spring barrel, 61, a constant force spring coil spring, 62, a spring runner, 63, a one-way damper, 7, a spring pulley, 8, a pull rope, 9 and a hanging ring.

Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

As shown in fig. 1-3, the constant force winding device for the charging pile comprises a cavity formed by a shell 1 and an upper cover 2, a charging assembly and a cable 3 are arranged in the cavity, the cable 3 extends to the outside through a through hole formed in the shell 1, a charging gun 31 is arranged at the tail end of the cable, the constant force winding device comprises a guide rail 4 arranged in the cavity, a supporting plate 5 with a fixed pulley 51 at the upper end is arranged at the top end of the guide rail 4, a spring box 6 is arranged at the bottom of the guide rail 4, a constant force winding mechanism is arranged in the spring box 6, the spring pulley 7 is connected with the constant force winding mechanism, a pull rope 8 is wound on the spring pulley 7, the pull rope 8 extends upwards to bypass the fixed pulley 51 and then is connected with a lifting ring 9, and the cable 3 is sleeved in the lifting ring 9 and fixedly connected with the lifting ring 9.

In another embodiment of the present utility model, the constant force winding mechanism includes a constant force winding spring 61 and a winding wheel 62 provided at the middle of the constant force winding spring 61, the winding wheel 62 having a unidirectional damper 63 thereon.

In another embodiment of the present utility model, the pulling rope 8 is a metal rope.

The charging gun 31 is pulled, one end of the pull rope 8 is connected with the hanging ring 9 of the cable 3 because the hanging ring 9 of the cable 3 is locked on the cable 3, and the other end of the pull rope is fixed on the end plate of the supporting plate 5. The cable 3 drives the pull rope 8 to pull outwards, and the pull rope 8 drives the constant force spring coil spring 61 to move upwards along the guide rail 4 under the support of the fixed pulley 51 and the spring pulley 7. When the distance between the charging gun 31 and the target point is reached, the pulling force for pulling the charging gun 31 stops, at this time, the constant force spring coil 61 is wound back, the tail end of the constant force spring coil 61 is in the shape of a hook and is buckled in the groove of the spring rotating wheel 62, the spring rotating wheel 62 is provided with a circular locking and self-unlocking track, and the spring box 6 is combined into a locking and self-unlocking device. When the constant force spring 61 is rewound, the spring runner 62 is driven to rotate, after a certain length, the circulation locking function on the spring runner 62 is activated, the spring runner 62 is locked to rotate, the constant force spring 61 is also limited by the locking of the spring runner 62, the rolling force is also locked, and all devices temporarily stop working.
