[0027] The following elaborates on the preferred embodiments of the present utility model in detail with reference to the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Refer to Figure 1 and Figure 2As shown in the figure, this embodiment provides a charging device for an electric vehicle, which includes a charging gun 2, a box body 1, a moving mechanism 3, a robotic arm 6, a cable 7, a sensing module 8, a camera 9, a slider 33, and a display screen 10.

[0029] Further, the charging gun 2 is configured to be inserted into the charging port of the electric vehicle to charge the electric vehicle. A bus bar for providing electric energy is arranged in the box body 1, and the charging gun 2 is electrically connected to the bus bar through the cable 7. Specifically, in this embodiment, a bus bar is provided in the box body 1, and the bus bar is connected to a photovoltaic energy storage system and powered by the electricity generated by the photovoltaic panel. In other embodiments, the bus bar can also be connected to the power grid and powered by the power grid. At least one part of the cable 7 is fixed on the robotic arm 6. Referring to Figure 1 As shown in the figure, the cable 7 is located below the robotic arm 6 and is connected to the robotic arm 6 through a plurality of cable clamps 71. The cable clamps 71 can effectively prevent the cable 7 from falling off the robotic arm 6.

[0030] The slider 33 is movably arranged on the box body 1. An opening area 11 is provided on the box body 1, and the display screen 10 is located above the opening area 11. The display screen 10 is used to display information such as charging time and date, charging amount of the electric vehicle, charging current, charging voltage, and temperature. Specifically, the slider 33 is movably arranged on the opening area 11, which can expand the stroke range of the robotic arm 6 or the charging gun 2 and ensure that the charging gun 2 can successfully charge the electric vehicle.

[0031] Combined with Figure 1 and Figure 2 As shown in the figure, the moving mechanism 3 is arranged inside the box body 1, which can play a role in dust prevention and extend the service life of the charging device.

[0032] Further, the moving mechanism 3 includes a first driving motor 34, a second driving motor 31, a transmission component 32, a support frame 325, and a base 312. The second driving motor 31 is arranged on the base 312. Specifically, the second driving motor 31 is fixed on the base 312 through bolts 313. The output shaft 311 of the second driving motor 31 is connected to the transmission component 32. The transmission component 32 is connected to the slider 33 through a connecting piece 331, and the first driving motor 34 is fixedly connected to the slider 33.

[0033] Furthermore, the transmission component 32 includes a lead screw 321, a driving wheel 323, and a driven wheel 324 arranged on the lead screw 321. The driving wheel 323 is connected to the output shaft 311, the driven wheel 324 meshes with the driving wheel 323, and a lead screw support frame 325 is used to support the lead screw 321. When the charging device is working, the output shaft 311 of the first driving motor 31 rotates and drives the driving wheel 323 and the driven wheel 324 to rotate. The driven wheel 324 drives the lead screw 325 to rotate, and the slider 33 can move back and forth along the length direction of the lead screw 325 until the position of the charging gun 2 in the horizontal direction is determined.

[0034] One end of the robotic arm 6 is connected to the first driving motor 34, and the other end is connected to the charging gun 2. The robotic arm 6 includes a first robotic arm 61 and a second robotic arm 62. The first driving motor 34 is located between the first robotic arm 61 and the slider 33. While the slider 33 moves horizontally, the first robotic arm 61, the second robotic arm 62, and the charging gun 2 will also move horizontally. The first driving motor 34 drives the first robotic arm 61, the second robotic arm 62, and the charging gun 2 to rotate; a third driving motor 4 is provided between the first robotic arm 61 and the second robotic arm 62, and the third driving motor 4 drives the second robotic arm 62 and the charging gun 2 to rotate. A fourth driving motor 5 is provided between the second robotic arm 62 and the charging gun 2, and the fourth driving motor 5 drives the charging gun 2 to rotate.

[0035] Furthermore, the first robotic arm 61 is connected to the rotor 41 of the first driving motor 34, the second robotic arm 62 is connected to the rotor of the third driving motor 5, and the charging gun 2 is connected to the rotor of the fourth driving motor 5. The rotation of the rotor 41 drives the first robotic arm 61, the second robotic arm 62, and the charging gun 2 to rotate to adjust the angle until the charging gun 2 moves near the charging port of the electric vehicle.

[0036] The charging device further includes a controller, which is electrically connected to the first driving motor 31, the second driving motor 34, the third driving motor 4, the fourth driving motor 5, the induction module 8, and the camera 9 respectively.

[0037] The induction module 8 is used to control the automatic opening and closing of the charging cover of the electric vehicle. The induction module 8 has electronic induction and control components. When the induction module 8 reaches beside the vehicle cover and senses the vehicle cover, it can then control the opening and closing of the vehicle cover. Specifically, the induction module 8 is provided on the charging gun 2. When charging is required, the induction module 8 can control the automatic opening of the charging cover of the electric vehicle; when charging is completed, the induction module 8 can control the automatic closing of the charging cover of the electric vehicle, that is, the entire charging process of the electric vehicle does not require manual operation, and automated operation can be achieved, which is relatively convenient to use.

[0038] The camera 9 is also provided on the charging gun 2. After the electric vehicle drives into the charging area, the charging device receives a charging signal, and the camera 9 takes a photo of the electric vehicle and uploads the photo to the controller.

[0039] The working principle of the charging device in this embodiment is as follows:

[0040] After receiving the charging signal, the charging device first takes a picture of the electric vehicle through the camera 9, and then uploads the photo to the controller. The controller sends a signal, and the second drive motor 31 drives the slider 33 to move horizontally within the opening area 11 to adjust the position to find a suitable charging position. After determining the position, the first drive motor 34 drives the first robotic arm 61 to move, the third drive motor 4 drives the second robotic arm 62 to move, and the fourth drive motor 5 drives the charging gun 2 to move. The first robotic arm 61, the second robotic arm 62, and the charging gun 2 adjust the angular position so that the charging gun 2 stays at a certain position above the vehicle charging cover. Then the controller issues an instruction to the induction module 8 to automatically open the charging cover. The charging gun 2 is inserted into the charging port for charging. After charging is completed, the charging gun 2 leaves the charging port, and the induction module 8 controls the charging cover to automatically close, and the robotic arm 6 returns to the initial position. The whole process is automated and does not require manual operation.

[0041] The charging device of this embodiment has at least the following advantages:

[0042] (1) The slider 33 can move horizontally along the box body 1, expanding the stroke of the robotic arm 6 or the charging gun 2;

[0043] (2) Before and after charging, the charging cover at the rear of the vehicle can be opened without manual operation, with a relatively high degree of automation and convenient use;

[0044] (3) The first robotic arm 61 and the second robotic arm 62 can adjust the angle, which is beneficial for the charging gun to reach the charging port;

[0045] (4) Solve the problem that traditional charging piles do not have the function of automatic charging and improve the utilization rate of charging piles.
