Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to an automatic charging pile wire collector. Background Art

[0002] The charging pile cable retractor is a device used to retract and release cables. It can effectively solve the problems of cables dragging on the ground and being placed randomly during electric vehicle charging, improve charging efficiency and safety, reduce occupied space, and improve the overall aesthetics of the charging station. It is an important part of electric vehicle charging equipment. It can improve charging efficiency and safety and provide electric vehicle users with a better charging experience.

[0003] The publication number is: CN207697515U, which discloses a charging pile with a cable reel, belonging to the technical field of charging piles. The charging pile with a cable reel comprises a power supply pole, a cable reel mounted on one side of the power supply pole, a cable coiled in the cable reel, and a rainproof eaves arranged on the top of the power supply pole. The technology can conveniently store the cable of the charging pile to prevent the cable from being damaged by the friction of the cable being dragged on the ground. At the same time, the large rainproof eaves on the top prevent rain from wetting the cable and the charging gun, thereby extending the service life of the charging pile. In daily use, the cable reel needs to be manually wound and stored, which will consume more time and labor. Due to the lack of automatic winding function, the wires are easily placed randomly when not in use, resulting in chaos in the workplace and inconvenient management and storage of the wires. Cables that are left for a long time or dragged at will may be physically damaged, such as wear and tear, which will reduce the service life of the wires and increase the cost of repair or replacement. Therefore, there is still room for modification of the technology. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide an automatic charging pile wire collector in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic charging pile wire collector, comprising a mounting base, a first swing arm, and a second swing arm. The first swing arm can be rotatably mounted on the mounting base, and the first swing arm and the second swing arm are hinged, characterized in that: a mounting cavity for installing a volute spring is provided at the bottom of the mounting base, and the first swing arm and the mounting base are rotatably connected by setting a first central axis, and the first central axis extends into the mounting cavity. The volute spring is sleeved on one end of the first central axis located in the mounting cavity, and a return end is provided at one end of the volute spring. A return groove is provided on the inner wall of the mounting cavity to be clamped with the return end, and a connecting ring is provided at one end of the second swing arm for hanging an external charging cable. A rebound structure is also provided between the first swing arm and the second swing arm.

[0006] By adopting the above technical solution, the installation cavity at the bottom of the mounting seat provides a hidden installation space for the spiral spring. There is no need to install other components additionally, and the installation is easier. Since the return end of the spiral spring is engaged with the return groove in the installation cavity, when the first swing arm rotates, the spiral spring in the mounting seat is deformed. After the charging pile is used, the cable is released and the spiral spring of the first swing arm rebounds to return to complete the return of the first swing arm. The charging cable is suspended on the connecting ring of the second swing arm. When the first swing arm returns, it drives the second swing arm with it. At the same time, a rebound structure is provided between the second swing arm and the first swing arm to pull the charging cable back to automatically recycle the charging cable.

[0007] The above-mentioned automatic recycling charging pile wire take-up device can be further configured as: the rebound structure includes a first connecting groove for connecting to the second swing arm, which is arranged at one end of the first swing arm away from the mounting seat; the second swing arm is connected to the first swing arm at one end, and a second connecting groove for installing a torsion spring is provided at the second connecting groove; the first swing arm and the second swing arm are hinged by setting a second central axis, the second central axis is passed through the first connecting groove and the second connecting groove, the torsion spring is sleeved on the second central axis and placed in the second connecting groove, and one end of the torsion spring is clamped with the first swing arm and the other end is clamped with the second swing arm.

[0008] By adopting the above technical solution, the torsion spring provides a stable elastic connection between the first swing arm and the second swing arm, which can effectively reduce the impact of vibration and external force generated during operation on the structure, and ensure the stable operation of the cable reel. The elastic action of the torsion spring enables the cable reel to automatically return to its position after releasing the cable. The user only needs to lightly relax, and the cable reel can automatically recycle the cable through the spiral spring and torsion spring, which simplifies the operation process and reduces the difficulty of use.

[0012] By adopting the above technical solution, the design of the baffle effectively blocks the installation cavity and protects sensitive components such as the internal lubricating sleeve and spiral spring. The first snap-in groove on the first central axis cooperates with the perforation of the baffle and the setting of the first snap ring to fix the position of the first central axis, simplifying the installation process and making installation more convenient.

[0013] The above-mentioned automatic charging pile wire collection device can be further configured as follows: a second clamping groove is provided at the end of the second central axis, a second clamping ring abutting against one end of the first swing arm is provided in the second clamping groove, and a wear-resistant sleeve is provided between the second central axis and the second swing arm.

[0014] By adopting the above technical solution, a second clamping groove is set at the second middle axis end and a second clamping ring is installed in the groove, so that a more precise articulation between the first swing arm and the second swing arm is achieved.
