DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a charging device for an electric vehicle comprises a pile body 1, charging ports 7 are arranged on the front, rear, left and right sides of the pile body 1, upper and lower telescopic frames 2 are welded on the front, rear, left and right sides of the pile body 1, the telescopic frames 2 are perpendicular to the sides of the pile body 1 fixed with the telescopic frames 2, telescopic columns 4 are slidably connected in the telescopic frames 2 through sliders and slide grooves, a first limiting component 5 capable of limiting the telescopic column 4 is arranged on the upper side of one of the telescopic frames 2, one end of the two telescopic columns 4 extending out of the telescopic frame 2 is rotatably connected to a U-shaped frame 3 through a rotating shaft 12, and a second limiting component 6 capable of preventing the U-shaped frame 3 from rotating is arranged on the side of the upper telescopic column 4 away from the telescopic frame 2.

[0021] When parking the electric vehicle, the user can release the limit of the telescopic column 4 by the first limiting assembly 5 and pull the telescopic column 4 to move in the direction away from the pile body 1. When the distance between the U-shaped frame 3 and the pile body 1 is large enough to accommodate the user's electric vehicle, the pulling is stopped. After stopping pulling, the user limits the telescopic column 4 through the first limiting assembly 5 to prevent the telescopic column 4 from sliding when not in use. Then the user releases the limit of the U-shaped frame 3 by the second limiting assembly 6 and rotates the U-shaped frame 3 until the U-shaped frame 3 is perpendicular to the side of the pile body 1. Then the user parks the electric vehicle on the outer side of the pile body 1, rotates the U-shaped frame 3 back to the initial position, and uses the second limiting assembly 6 to limit the U-shaped frame 3 to prevent the U-shaped frame 3 from rotating. Then the user can insert the charging cable of the electric vehicle into the charging port 7 for charging, thereby realizing the protection of the charging equipment for electric vehicles of different sizes and improving the practicability of the charging equipment.

[0022] In this embodiment, the first limiting assembly 5 includes a first limiting shell 503 fixed by bolts on the telescopic frame 2 located above, a limiting column 501 located in the first limiting shell 503, and a pull plate 502 welded to the upper end of the limiting column 501. The first limiting shell 503 is located on the upper side of the telescopic frame 2. The upper and lower ends of the limiting column 501 pass through the first limiting shell 503 and the telescopic frame 2 respectively. The telescopic column 4 is provided with a plurality of limiting holes 401 for the lower end of the limiting column 501 to be plugged in. The circumferential side of the limiting column 501 located in the first limiting shell 503 is integrally formed with an annular convex ring. The first limiting shell 503 is provided with a A spring 504 is arranged, and the spring 504 is connected to the upper side of the annular protrusion and the first limiting shell 503. When in use, the user can pull the pull plate 502 to make the limiting column 501 move upward and disengage from the limiting hole 401. Then the user can pull the telescopic column 4 to move back and forth in the telescopic frame 2 to adjust the distance between the U-shaped frame 3 and the outer side of the pile body 1. When the adjustment is completed, the user can release the pull plate 502. Under the action of the elastic force of the spring 504, the limiting column 501 moves downward and is inserted into the limiting hole 401 to prevent the telescopic column 4 from sliding in the telescopic frame 2, thereby improving the reliability of the charging device when in use.

[0023] In this embodiment, the second limiting assembly 6 includes a second limiting shell 601, a limiting plate 602 located in the second limiting shell 601, and a bottom cover 603 welded to the lower side of the second limiting shell 601. The limiting plate 602 is located in the second limiting shell 601. The side surface is integrally formed with a protrusion, and the upper and lower ends of the limiting plate 602 pass through the second limiting shell 601 and the bottom cover 603 respectively. When in use, the user can pull the limiting plate 602 to extend out of one end of the upper side of the second limiting shell 601, so that the limiting plate 602 moves upward until the lower side of the limiting plate 602 is flush with the lower side of the second limiting shell 601. At this time, the limiting plate 602 does not contact the U-shaped frame 3, and then the user can rotate the U-shaped frame 3 to be perpendicular to the pile body 1. Then the user can park the electric vehicle to the front side of the pile body 1, which improves the convenience of the user in parking the electric vehicle. After parking is completed, the user can rotate the U-shaped frame 3 back to the initial position to protect the electric vehicle.

[0024] In this embodiment, two reflective plates 11 are glued to the side of the U-shaped frame 3 away from the pile body 1, which are symmetrical in upper and lower directions. When in use, the reflective plates 11 can reflect external lights to remind pedestrians of the location of the charging equipment and electric vehicles, prevent pedestrians from colliding with the charging equipment or electric vehicles, and improve the safety of the charging equipment.

[0025] In this embodiment, the front, rear, left and right sides of the pile body 1 are hinged with a waterproof cover 10 located above the charging port 7. When in use, the waterproof cover 10 can be rotated to cover the front side of the charging port 7 to prevent rainwater from entering the charging port 7 when the charging port 7 is not in use, thereby ensuring the reliability of the charging port 7 when in use.

[0026] In this embodiment, lighting devices 8 are provided on the front, back, left and right sides of the pile body 1. The lighting device 8 can be a common electric lighting device such as an LED lamp. When in use, the lighting device 8 can illuminate the front side of the pile body 1, thereby improving the convenience of users when using it at night.
