The three joints are a first joint 12, a second joint 13 and a third joint 14. One end of the first joint 12 is used for bearing the charging plug 11, and the other end of the first joint 12 is connected with one end of the second joint 13 through the first rotating shaft 151; one end of the third joint 14 is connected to the other end of the second joint 13 via a second rotation shaft 152. The first rotating shaft 151 and the second rotating shaft 152 are respectively connected to a control system, and the control system can respectively control the first rotating shaft 151 and the second rotating shaft 152 to rotate, so that the first joint 12 can realize 180-degree rotation through the first rotating shaft 151, and the second joint 13 can realize 180-degree rotation through the second rotating shaft 152.

The second rotation device 80 is connected to the control system for rotating the robot arm in a plane parallel to the horizontal plane. Because the first rotating device 70 drives the mechanical arm to rotate in the plane perpendicular to the horizontal plane, and the second rotating device 80 drives the mechanical arm to rotate in the plane parallel to the horizontal plane, the mechanical arm can flexibly rotate in a three-dimensional space under the synergistic effect of the first rotating device and the second rotating device, the intelligence and the flexibility of the intelligent charging device are improved, the requirement on the intelligent charging parking position is lowered, and the convenience and the easiness of intelligent charging are improved.

If the mechanical arm starts to charge after the charging plug is inserted into the charging socket, the charging current flows through the internal circuit connecting wire of the mechanical arm, the charging current detection unit detects the charging current, and the charging is indicated, otherwise, the charging is not performed. When the mechanical arm inserts the charging plug into the charging socket to fully charge the electric vehicle, the charging current can be stabilized below a small threshold value. If the charging current detection unit detects that the charging current is smaller than the preset threshold, it can be determined that the battery is fully charged.
Further, in the above embodiment, an indicator light may be further provided to indicate whether charging is completed. When the charging current is less than the preset threshold value, the indicator lamp can be lightened or the color of the indicator lamp can be changed to inform people that the vehicle is fully charged. For example, when the vehicle is normally charged, the indicator lamp is green to inform people that the vehicle is being charged; when the vehicle battery is fully charged, the indicator light may appear red to inform a person that it is fully charged. The indicating lamp is not lightened when the vehicle battery is fully charged, and the indicating lamp is lightened to inform people that the vehicle battery is fully charged. In this embodiment, if the charging current detection unit is connected to the control system, when the charging current detection unit detects that the vehicle is fully charged, the charging current detection unit may send a vehicle charge full signal to the control system, and the control system controls the mechanical arm to pull the charging plug out of the charging socket of the electric vehicle based on the vehicle charge full signal; and the control system can control the sound device to give out a charging completion sound prompt to prompt the car owner that charging is completed, so that the car can be driven away.
Further, in the intelligent charging device in the above embodiment, the vehicle detection unit may include a distance measurement sensing device for detecting distance information between the vehicle and the intelligent charging device. The vehicle detection unit is connected with the control system, the control system controls the sound device to give out sound warning based on the distance information detected by the vehicle detection unit, the vehicle owner is prompted that the vehicle is close to the intelligent charging device, meanwhile, the control system can control the mechanical arm to rotate towards one side far away from the vehicle, and the situation that the vehicle is inadvertently contacted with the mechanical arm in the process of being close to the intelligent charging device, and therefore the vehicle is scratched is avoided.

The alignment unit can acquire image information and/or distance information of the vehicle and send the image information and/or distance information to the control system, and the control system controls each joint to execute preset actions based on the acquired image information and distance information of the charging socket so that the charging plug is accurately inserted into the charging vehicle; and can be based on the distance information control arm of vehicle to keeping away from the one side rotation of vehicle, avoid the vehicle in the in-process of being close to intelligent charging device, carelessly with vehicle and arm contact, lead to the vehicle fish tail.
Further, as shown in fig. 3, the intelligent charging device provided in one embodiment of the present application further includes a first sensing strip 17 and a second sensing strip 18. The first sensing strip 17 may be disposed outside the intelligent charging device, or may be disposed at a position within a second distance range from the intelligent charging device; the second sensing strip 18 may be disposed at a position within a third distance range from the smart charging device, and the first sensing strip 17 and the second sensing strip 18 together define a chargeable range of the vehicle. Fig. 3 illustrates that the first sensing strip 17 is disposed on the outer sidewall of the charging base, and the second sensing strip 18 is disposed on the ground within a predetermined distance range away from the first sensing strip 17.
Specifically, when the vehicle detection unit detects that there is an electric vehicle needing charging, a vehicle charging signal is generated and sent to the vehicle control system, and the control system can control the mechanical arm to charge the vehicle based on the vehicle charging signal. Because the extension range that the arm drove charging plug is limited, and the parking scope that intelligent charging device can realize automatic charging is difficult to accurately predict again when the driver charges. Therefore, according to the space extension range of the mechanical arm driving the charging plug to realize automatic charging, the first sensing strip 17 is arranged on the outer side wall of the charging base, the second sensing strip 18 is arranged on the ground far away from the first sensing strip 17 within a preset distance range, or the second sensing strip 18 is arranged on the limiting device 19, as shown in fig. 3.
