Description

TECHNICAL FIELD

[0001] The application belongs to the field of charging piles, and particularly relates to an electric vehicle charging pile with a wire winding mechanism. BACKGROUND

[0002] A charging pile is a device for supplementing the energy of an electric vehicle. According to different scene requirements, charging piles are generally divided into two types. One is a household charging pile, which is usually used and maintained by an electric vehicle owner. The other is a public charging pile, which is usually installed at a charging station, a shopping mall, a public parking lot and a community underground parking lot, and provides services for electric vehicle owners in need.

[0003] However, the existing charging pile has a wire that is mostly exposed outside the charging pile body. The wire is subjected to problems such as long-term rain, sunlight and human trampling, which causes the charging gun and cable to be easily aged and damaged, affecting the service life of the charging pile.

[0004] In view of the above technical problems, the applicant has searched some existing patents, such as a wire winding device of an electric vehicle charging pile with patent number CN222476187U. The wire winding device is provided with a winding box on the charging pile. A winding drum is rotatably arranged in the winding box. The charging wire can be wound on the winding drum, thereby completing the storage of the charging wire and preventing the charging wire from being exposed to the outside, thereby preventing the cable from aging.

[0005] However, in the use scene of the public charging pile, most of the public charging piles have a fast charging mode. The charging wire used by the charging pile has a relatively large overall weight. Compared with the slow charging cable, the charging wire is thicker and more flexible. When the thick charging cable is wound and stored, due to the limited bending degree, after the cable is wound on the winding drum, the cable has a tendency to return to a horizontal state, that is, the cable has a tendency to spread outward. Since one end of the cable is connected to the charging gun, the charging gun is inserted into the socket on the charging pile, the cable always has an outward pulling force on the charging gun. After long-term use, deformation may occur between the charging gun and the socket, causing the charging gun and the socket to loosen, thereby reducing the service life of the charging pile. SUMMARY

[0044] When the charging cable 3 is installed, one end of the charging cable 3 will pass over the edge of the cloth plate 757 and extend out of the winding drum 74, and when the charging cable 3 is wound, the servo motor 71 drives the winding drum 74 to rotate, and under the action of the larger friction force, the winding drum 74 drives the charging cable 3 inside the winding drum 74 to rotate, and since the guide rod 756 is fixed, the angle of the cloth plate 757 relative to the horizontal plane does not change, thereby causing the cloth plate 757 to move relative to the winding drum 74, and when the winding drum 74 rotates, the cloth plate 757 moves along the spiral groove 751, so that the cloth plate 757 extrudes the charging cable 3 into the cable groove 76, thereby realizing the winding of the charging cable 3.

[0045] As shown in Figures 1-5 the charging pile with the winding mechanism 7 provided by the application, when the cloth plate 757 and the charging cable 3 move relative to each other, in order to avoid damage to the surface of the charging cable 3 caused by the cloth plate 757, in the embodiment, the cloth mechanism 75 further comprises a guide plate 7512 fixedly connected to the side of the cloth plate 757, the guide plate 7512 is arc-shaped, and the plane of the outermost end of the guide plate 7512 is parallel to the axis of the winding drum 74, so that the guide plate 7512 can support and guide the charging cable 3, avoiding scratching between the edge of the cloth plate 757 and the charging cable 3, and the outermost end of the guide plate 7512 is provided with a rotating guide roller 7511, which can reduce the friction between the guide plate 7512 and the charging cable 3, so that the user can pull the charging cable 3 more easily;

[0047] As shown in Figures 1-5 the charging pile with the winding mechanism 7 provided by the application, after the cloth plate 757 winds the charging cable 3 into the winding drum 74, due to the characteristics of the charging cable 3 being more flexible, the wound charging cable 3 may be loosened and dislocated, thereby causing the subsequent charging cable 3 to be unable to be wound neatly, therefore, in the embodiment, the cloth mechanism 75 further comprises a limiting baffle 752, the limiting baffle 752 is slidingly installed in the spiral groove 751, the side of the limiting baffle 752 is fixedly connected to the sliding column 753 through connecting rods 755, and the included angle between the two connecting rods 755 in the same vertical plane is 180°.

[0048] When the charging cable 3 is wound on the cloth plate 757, the limiting baffle 752 extrudes and limits the charging cable 3, so that the charging cable 3 is always kept in the cable groove 76, so that the charging cable 3 is more orderly wound, and the mutual entanglement of the charging cable 3 is avoided.

[0051] When the charging cable 3 is rotated by the winding drum 74, the charging cable 3 can only tightly adhere to the side wall of the winding drum 74 due to the blocking of the limiting baffle rod 754, so that the scattering of the charging cable 3 is avoided.

[0052] As shown in Figures 1-3 and Figures 6-9As shown, the application provides an electric vehicle charging pile with a take-up mechanism 7.

[0055] In order to avoid the charging cable 3 from coming out between the two clamping blocks 64, a limiting strip 610 matched with the charging cable 3 is fixedly connected to the two inner side surfaces of the mounting bracket 61.

[0056] In order to cut off the power supply of the electromagnetic clutch 72 in time, an angle sensor 66 is fixedly installed on the side surface of the mounting bracket 61, one end of the detection tube 69 is connected with the input end of the angle sensor 66, when the user pulls the charging cable 3 to move, the charging cable 3 will drive the detection tube 69 to rotate, the angle sensor 66 will detect the rotation angle of the detection tube 69, when the rotation angle exceeds the preset value of the angle sensor 66, the power supply of the electromagnetic clutch 72 will be cut off, thereby avoiding the situation that the power supply of the electromagnetic clutch 72 is cut off due to the shaking of the charging cable 3 caused by the collision of the external environment, and improving the protection effect on the charging cable 3.
