The two ring bodies are respectively conductively fixedly connected to the positive and negative wires on the cable line, and the ring bodies are conductively slidingly abutted against the corresponding conductive ring pieces.

[0006] Preferably, the overall shape formed by the insulating tube and the two ring bodies is an I-shape, and the insulating tube is made of elastic rubber material.

[0007] Preferably, a central groove is formed at the center of the central column, and a receiving groove is symmetrically formed inside the central column. Both receiving grooves are connected to the central groove, wherein the receiving groove and the central groove are used for the passage of the positive and negative wires of the cable on the charging pile.

[0008] Preferably, rollers are symmetrically arranged inside the wire hole, rubber protective sleeves are fixedly arranged on the rollers, and the cable is located between the two rollers.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Embodiment 1, by Figure 1-5 The utility model relates to a charging pile cable storage drum device, comprising a charging pile 1 and a storage shell 2. The storage shell 2 is fixedly arranged on the outer wall of the charging pile 1. A central column 3 is fixedly arranged on the inner side of the storage shell 2. A spiral spring 4 is fixedly arranged on the outer side of the central column 3. A cable 5 is fixedly arranged around the outer side of the spiral spring 4. A wire hole 6 is formed on the storage shell 2. A charging connector 7 is fixedly arranged on one end of the cable 5 passing through the wire hole 6. An electric contactor is fixedly arranged on the end of the cable 5 close to the spiral spring 4. Conductive ring pieces 8 are symmetrically fixedly arranged on the inner side of the storage shell 2. The two conductive ring pieces 8 are respectively in sliding contact with the two ends of the electric contactor. The two conductive ring pieces 8 are respectively fixed to the positive and negative wires of the cable on the charging pile 1.

[0025] With this design, when not in use, the spiral spring 4 causes the cable 5 to wrap around the outside of the spiral spring 4, thereby storing the cable 5. When in use, the user only needs to take out the charging connector 7 from the charging pile 1, and then pull the charging connector 7 to extend the cable 5 from the storage shell 2 to facilitate charging operations; due to the setting of the spiral spring 4, the cable 5 will not be dragged on the ground and rubbed due to its excessive length, thereby protecting the cable 5.

[0026] Specifically, the electrical contactor includes an insulating tube 9 fixedly arranged at the connection between the spiral spring 4 and the cable 5, a circular hole 10 is formed on the insulating tube 9, and a ring body 11 is fixedly provided at both ends of the insulating tube 9. The two ring bodies 11 are respectively conductively fixedly connected to the positive and negative pole wires on the cable 5, and the ring bodies 11 are conductively slidingly abutted against the corresponding conductive ring pieces 8; with this design, the two ring bodies 11 are in sliding contact with the two conductive ring pieces 8 respectively, thereby realizing a sliding conductive method, so as to facilitate the transfer of electricity from the charging pile 1 to the charging connector 7 on the cable 5.

[0027] The overall shape formed by the insulating tube 9 and the two ring bodies 11 is an I-shape, and the insulating tube 9 is made of elastic rubber material; with this design, the insulating tube 9 can make the ring body 11 and the corresponding conductive ring piece 8 closely contact each other to ensure the stability of the contact between the two.

[0028] A central groove 12 is formed at the center of the central column 3, and a receiving groove 13 is symmetrically formed inside the central column 3. The two receiving grooves 13 are both connected to the central groove 12, wherein the receiving groove 13 and the central groove 12 are both used for the passage of the positive and negative wires of the cable on the charging pile 1.

[0029] There are also symmetrically rotating rollers 17 inside the wire hole 6, and rubber protective sleeves are fixed on the rollers 17. The cable 5 is located between the two rollers 17. This design can avoid direct contact between the cable 5 and the wire hole 6 to cause wear, and play a protective role for the cable 5.

[0030] A speed limiter for controlling the rotational speed of the roller 17 is also provided in the wire hole 6. The speed limiter includes a telescopic spring 14 symmetrically arranged and fixed to the inner wall of the wire hole 6. A limit plate 15 is fixedly provided on the telescopic spring 14. An arc groove is formed on the side of the limit plate 15 close to the roller 17, which abuts against the roller 17. With this design, the roller 17 is subjected to friction during rotation through the action of the telescopic spring 14, thereby preventing the cable 5 from suddenly entering the interior of the storage shell 2 under the action of the spiral spring 4.

[0031] The outer wall of the charging pile 1 is also fixedly provided with a storage box 16 for accommodating the charging connector 7. The storage box 16 is located above the storage shell 2. This design facilitates the protection of the charging connector 7 by the storage box 16.
