Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging technology. It discloses an automatic telescopic device for a DC charging gun. Background Technology

[0002] DC charging stations for new energy vehicles have large-diameter and heavy internal cables, making them difficult to drag and requiring considerable effort from personnel. This is especially true for outdoor charging stations in northern regions, where it is difficult for women to drag the charging gun themselves to fast charge their vehicles.

[0003] Currently, the charging guns of DC charging piles on the market have a maximum charging current of 250A, a cable outer diameter of 42mm, and a general length of 5 meters. Some charging guns have cable harnesses that are more than ten meters long and are very heavy. When charging, dragging the charging gun cable harness back and forth on the ground can cause serious wear on the insulation layer, which poses a safety hazard. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automatic telescopic device for DC charging guns, in which the charging cable is suspended in the air, avoiding friction with the ground and facilitating dragging, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: an automatic telescopic device for DC charging gun, comprising a column, a crossbeam, and a charging cable connected to the pile body. One end of the column protrudes to form a fixing part, and a top shell is fitted over the fixing part. A bearing is installed between the top shell and the fixing part. One end of the crossbeam is mounted on the top shell. A drive mechanism for rotating the top shell and the crossbeam is mounted on the fixing part. The crossbeam is provided with a sliding groove, in which multiple sliders are installed. One slider is equipped with a first fixing rod, and the remaining sliders are equipped with second fixing rods. The other end of each second fixing rod is equipped with a positioning ring. The other end of each charging cable passes through the positioning ring and is equipped with a charging gun.

[0006] In this embodiment, a limiting ring is installed at the other end of the first fixing rod, and the limiting ring is sleeved on the charging cable near the charging gun.

[0007] In this embodiment, the drive mechanism includes a motor and multiple connecting rods. The fixing part is provided with a mounting groove, the motor is installed in the mounting groove, the motor shaft extends into the top shell, one end of each connecting rod is installed on the shaft, and the other end is installed on the inner wall surface of the top shell.

[0008] In this embodiment, the motor is a brake motor, and a wiring channel communicating with the mounting slot is formed inside the column. A wiring conduit communicating with the wiring channel is installed at the end of the column away from the top shell.

[0009] In this embodiment, both the slider and the groove have a "T" shaped cross-section.

[0010] In this embodiment, the charging cable is equipped with side rings on both sides of the positioning ring, and the diameter of the side rings matches the diameter of the positioning ring.

[0011] In this embodiment, the diameters of the top shell and the column are matched.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure, and the drive mechanism can drive the crossbeam, charging cable and charging gun to rotate, increasing the range of movement of the charging gun. After the charging gun moves and extends along the slide, it can change the distance between the front and back to adapt to the charging operation of vehicles in different parking spaces. Furthermore, the crossbeam and positioning ring can suspend the charging cable in the air, avoiding friction with the ground and facilitating dragging. Attached Figure Description

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an automatic telescopic device for a DC charging gun, comprising a column 1, a crossbeam 3, and a charging cable 9 connected to the pile body. One end of the column 1 protrudes to form a fixing part 16, and a top shell 2 is sleeved on the outside of the fixing part 16. A bearing 17 is installed between the top shell 2 and the fixing part 16. One end of the crossbeam 3 is installed on the top shell 2. A drive mechanism for rotating the top shell 2 and the crossbeam 3 is installed on the fixing part 16. The crossbeam 3 is provided with a sliding groove 12, in which multiple sliders 13 are installed. One slider 13 is equipped with a first fixing rod 4, and the remaining sliders 13 are equipped with second fixing rods 6. The other end of each second fixing rod 6 is equipped with a positioning ring 5. The other end of the charging cable 9 passes through the positioning ring 5 and is equipped with a charging gun 8.

[0020] In this embodiment, a limiting ring 7 is installed at the other end of the first fixing rod 4. The limiting ring 7 is sleeved on the charging cable 9 near the charging gun 8. The limiting ring can restrict the charging cable near the charging gun and reduce the swing amplitude.

[0021] In this embodiment, the drive mechanism includes a motor 14 and multiple connecting rods 15. The fixing part 16 is provided with a mounting groove, the motor 14 is installed in the mounting groove, the rotating shaft of the motor 14 extends into the top shell 2, one end of each connecting rod 15 is installed on the rotating shaft, and the other end is installed on the inner wall surface of the top shell 2.

[0022] In this embodiment, the motor 14 is a brake motor, the inside of the column 1 forms a wiring channel that communicates with the mounting slot, and a wiring pipe 11 that communicates with the wiring channel is installed at the end of the column 1 away from the top shell 2.

[0023] In this embodiment, both the slider 13 and the slide groove 12 have a "T" shaped cross section, which allows the slider to move back and forth along the slide groove, thus preventing it from falling off the crossbeam.

[0024] In this embodiment, the charging cable 9 is equipped with side rings 10 on both sides of the positioning ring 5. The diameter of the side rings 10 matches the diameter of the positioning ring 5. The side rings can restrict the charging cable to the positioning ring. After the charging cable is pushed inward, the section of the charging cable between the positioning rings will be bent downward, so that the charging cable can move towards the side of the column.

[0025] In this embodiment, the diameters of the top shell 2 and the column 1 are matched to ensure the flatness of the surface.

[0026] Working principle: The wires on the motor pass through the wiring channel and wiring pipe to the pile body and are connected to the controller. The controller can be installed on the pile body and can control the rotation of the motor. When in use, the motor can be started by the controller, so that the motor can rotate forward or reverse. The rotation of the motor drives the connecting rod, and the rotation of the connecting rod drives the top shell, so that the top shell rotates along the outer ring of the bearing. The top shell then synchronously drives the crossbeam, the first fixed rod, the second fixed rod, the charging cable and the charging gun. During rotation, to prevent the charging gun from colliding with adjacent vehicles, the charging line can be pushed along the slide towards the column. The movement of the charging gun drives the slider, the first fixed rod, and the second fixed rod, allowing the charging line to bend in the middle and bringing the sliders closer together until the charging gun is close to the column. After rotating to a suitable angle, the charging gun can be pulled outwards, allowing it to move into the vehicle's charging port and be plugged in. The suspension of the charging cable prevents it from rubbing against the ground and also facilitates dragging.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
