Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a charging robot. Background Art

[0002] With the development and popularization of new energy vehicles, charging piles have become necessary equipment. Charging piles are a type of energy replenishment device that provides power for electric vehicles. Their function is similar to that of a gas pump in a gas station. They can be fixed on the ground or on a wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. They can charge various types of electric vehicles according to the adjusted voltage and current.

[0003] Underground parking lots will be equipped with special charging piles for new energy vehicles, but there is a problem when using the current charging piles. After the user puts the car in the garage to charge, he usually does not wait in the car all the time. He usually waits until he gets off work or finishes things at night before returning to the garage to pick up the car. If the charging head is not unplugged from the car in time after charging is completed, the charging head will continue to charge the vehicle. Therefore, the existing charging piles cannot automatically unplug the charging head after charging is completed. Therefore, the utility model proposes a charging robot. Utility Model Content

DETAILED DESCRIPTION

[0021] 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 of 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.

[0022] like Figure 1-Figure 4 As shown, it relates to a charging robot, including a base 1, a horizontal plate 6 and a controller 13. A charging pile 2 is fixed on the upper surface of the base 1, and the charging pile 2 is connected to a charging line 21, and the other end of the charging line 21 is connected to a charging head 22. A moving component for driving the horizontal plate 6 to move is installed on the upper surface of the base 1, and a bottom shell 8 is fixedly connected to the lower surface of the horizontal plate 6. A guide rod 9 is fixed to the inner wall of the bottom shell 8, and a moving plate 10 is slidably sleeved on the surface of the guide rod 9. A mounting hoop 11 for installing the charging head 22 is fixed to the bottom end of the moving plate 10, a driving component 12 for driving the moving plate 10 to move is installed inside the bottom shell 8, and a positioning component 7 is installed on the upper surface of the horizontal plate 6.

[0023] The positioning assembly 7 includes a vertical plate 71 fixed to the upper surface of the horizontal plate 6 . A positioning camera 72 is fixed on the surface of the vertical plate 71 , and the positioning camera 72 is electrically connected to the controller 13 .

[0024] The position of the vehicle charging port can be located by positioning the camera 72 so that the charging head 22 can be subsequently inserted into the charging port.

[0025] The moving component includes a first linear motor 3 fixed on the upper surface of the base 1, a vertical second linear motor 4 is fixed to the moving end of the first linear motor 3, a third linear motor 5 is fixed to the moving end of the second linear motor 4, a horizontal plate 6 is fixedly connected to the moving end of the third linear motor 5, and the first linear motor 3, the second linear motor 4, the third linear motor 5 and the charging pile 2 are all electrically connected to the controller 13.

[0026] The movement of the first linear motor 3 , the second linear motor 4 , and the third linear motor 5 can drive the transverse plate 6 to move in the three axial directions of XYZ, and the transverse plate 6 then drives the charging head 22 to move, so that the charging head 22 can be accurately inserted into the charging port.

[0027] The charging head 22 is located inside the mounting hoop 11 , and the charging head 22 is fixed inside the mounting hoop 11 by bolts.

[0028] The charging head 22 can be fixed to the bottom of the movable plate 10 through the mounting hoop 11, and the charging head 22 can be disassembled for maintenance.

[0029] The driving assembly 12 includes a servo motor 121 fixed to the outer wall of the bottom shell 8 . The driving end of the servo motor 121 is fixedly connected to a screw rod 122 . The screw rod 122 passes through the moving plate 10 and is threadedly connected to the moving plate 10 . The servo motor 121 is electrically connected to the controller 13 .

[0030] The servo motor 121 drives the screw rod 122 to rotate, and the screw rod 122 drives the movable plate 10 to move along the guide rod 9. When the movable plate 10 moves to the outside of the bottom shell 8, it drives the charging head 22 to move out from the inside of the bottom shell 8. When the movable plate 10 moves to the inside of the bottom shell 8, it drives the charging head 22 to be stored in the bottom shell 8.

[0031] A strip-shaped opening 81 is formed on the lower surface of the bottom shell 8. When the charging head 22 moves in the bottom shell 8, the strip-shaped opening 81 provides a moving space for the charging cable 21.

[0032] Working principle: When charging, the positioning camera 72 first determines the position of the car charging port, and the positioning camera 72 feeds back the position information to the controller 13. Then the controller 13 controls the first linear motor 3, the second linear motor 4, and the third linear motor 5 to cooperate and move to drive the horizontal plate 6 to move, thereby realizing the movement of the charging head 22 and the bottom shell 8, so that the charging head 22 is aligned with the charging port, and then the controller 13 controls the servo motor 121 to drive the screw rod 122 to rotate, and the screw rod 122 drives the moving plate 10 to move along the guide rod 9, so that the moving plate 10 moves out of the bottom shell 8, thereby driving the charging head 22 to move out of the bottom shell 8 and insert it into the car charging port. When the charging pile 2 detects that charging is completed, the controller 13 first controls the servo motor 121 to reverse, drive the charging head 22 back into the bottom shell 8, and then controls the first linear motor 3, the second linear motor 4, and the third linear motor 5 to move and reset.
