[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please see Figures 1 to 7 The present invention provides a technical solution: An adaptive robotic arm intelligent charging pile includes a main body and a charging mechanism, with the charging mechanism mounted on the main body. The main body is electrically connected to the mains power supply and to the charging mechanism via wires. The main body provides power to the charging mechanism and can control the displacement of the charging mechanism to achieve an adaptive charging effect for electric vehicles. The charging mechanism can provide power to electric vehicles and can also control the movement of a protrusion 211 via a PLC controller. The protrusion 211 presses and pushes the charging compartment cover of the electric vehicle to open and close the cover. The invention also provides a rubber plug 213, which is compatible with the invention. The top portion of the rubber plug 213 has an integrally formed pull plate with an arc-shaped edge on its side to prevent the locking plate 212 from getting stuck inside the pull plate. A groove matching the protrusion 211 is also provided on the pull plate to cooperate with the locking plate 212 and fix the rubber plug 213 in place.

[0018] Reference Figure 1 and Figure 4 The main structure includes a pile body 11, a rotating seat 12, a first rotating arm 13, a bracket 14, a second rotating arm 18, a telescopic arm 19, and a base 110. The rotating seat 12 is rotatably connected to the pile body 11, and the bracket 14 is fixedly connected to the bottom of the rotating seat 12. One end of the first rotating arm 13 is rotatably connected to the bracket 14, and the other end of the first rotating arm 13 is rotatably connected to the second rotating arm 18. Both ends of the rotating seat 12 and the first rotating arm 13 have built-in motors. The output shaft of the motor in the rotating seat 12 is fixedly connected to the pile body 11, and the output shaft of the motor in the first rotating arm 13 is fixedly connected to one end of the bracket 14 and the second rotating arm 18, respectively. The motors are controlled by a PLC controller. When the motors are started, they can drive the rotating seat 12 to rotate, and can also drive the first rotating arm 13 to rotate around the bracket 14 as an axis, and can also drive the second rotating arm 18 to rotate around one end of the first rotating arm 13 as an axis. The telescopic arm 19 is slidably connected within the second rotating arm 18, and the base 110 is fixedly connected to one end of the telescopic arm 19. The telescopic arm 19 can extend and retract on the second rotating arm 18, thereby facilitating the control of the charging mechanism's position. Specifically, a base plate 181 is fixedly connected to the inner wall of the second rotating arm 18, a second motor 182 is mounted on one side of the base plate 181, and a screw 183 is fixedly connected to the output shaft of the second motor 182. The screw 183 is rotatably connected to the base plate 181, and the telescopic arm 19 is threadedly connected to the screw 183. In use, the second motor 182 is started by controlling the PLC controller, driving the screw 183 to rotate, causing the telescopic arm 19 on it to extend and retract along the second rotating arm 18 as an axis, thereby driving the charging mechanism to extend and retract. A sliding groove is provided on the inner wall of the second rotating arm 18, and a slider 184 is fixedly connected to the outer wall of the telescopic arm 19, slidingly connected within the sliding groove. The slider 184 works in conjunction with the sliding groove to prevent the telescopic arm 19 from deflecting.

[0019] The charging mechanism provides power to electric vehicles. The charging connector 25 of the charging mechanism is connected to the mains power supply. Power is provided to the electric vehicle by inserting the charging connector 25 into the charging port of the electric vehicle. The charging mechanism includes a U-shaped frame 21, a fixed housing 22, a rotating plate 24, a charging connector 25, a connecting rod 26, a fixed plate 27, a first motor 28, a lead screw 29, a push plate 210, a protrusion 211, and a clamping plate 212. The U-shaped frame 21 is mounted on the main body and fixedly connected to the base 110. The fixed housing 22 is fixedly connected to one side of the U-shaped frame 21. A motor is fixedly installed inside the fixed housing 22. The output shaft of the motor inside the fixed housing 22 is fixedly connected to the rotating plate 24. The motor controls the rotation of the rotating plate 24. The rotating plate 24 allows one side of the charging connector 24 or the protrusion 211 to face outwards. When the charging connector 24 faces outwards, it can be inserted into the charging port of the electric vehicle. When the protrusion 211 faces outwards, it can press the charging connector 25. The cover of the car charging compartment can be opened and rotated by the protrusion 211. After charging is completed, the cover is closed. At the same time, the rubber plug 213 on the charging interface can be pulled out and inserted. The charging connector 25 is installed on one side of the rotating plate 24. The connecting rod 26 is fixedly connected to the other side of the rotating plate 24. One end of the connecting rod 26 is fixedly connected to the fixing plate 27. One side of the fixing plate 27 is fixedly connected to the clamping plate 212. The first motor 28 is installed on the fixing plate 27 by bolts. The output shaft of the first motor 28 is fixedly connected to the lead screw 29, and the lead screw 29 is rotatably connected to the fixing plate 27. The push plate 210 is threaded to the lead screw 29 and slidably connected to the clamping plate 212. The protrusion 211 is fixedly connected to one side of the push plate 210. In use, the first motor 28 drives the lead screw 29 to rotate, thereby pushing the push plate 210 to move and driving the protrusion 211 to move. The outer material of the protrusion 211 is rubber. The protrusion 211 presses the electric vehicle charging compartment cover. After the cover is opened, the control plate 24 is rotated so that the end of the clamping plate 212 is locked inside the pull plate of the rubber plug 213. At this time, the first motor 28 is started, driving the push plate 210 to move, so that the protrusion 211 is inserted into the groove on the rubber plug 213, and the push plate 210 and the clamping plate 212 squeeze the pull plate of the rubber plug 213 to achieve the effect of fixing the rubber plug 213. The rubber plug 213 is pulled out by controlling the movement of the charging mechanism.

[0020] Furthermore, the pile body 11 is installed on the ground, the charging line inside the pile body 11 is electrically connected to the mains power, and the output end of the pile body 11 is electrically connected to the charging connector 25 through the wire.

[0021] Furthermore, a binocular camera 23 is mounted on the mounting housing 22. The binocular camera 23 can capture depth maps to identify the relative position of the charging mechanism and the electric vehicle charging interface.

[0022] Example 2: Please see Figure 1 and Figure 3 The present invention provides a technical solution: a take-up reel 31 is installed on the pile body 11, and a motor is installed inside the pile body 11. The motor drives the take-up reel 31 to rotate. An electric wire connected to the mains power is connected to the pile body 11. The electric wire is wound on the take-up reel 31. When in use, the electric wire is taken up and discharged by controlling the rotation of the take-up reel 31, which prevents the electric wire from dragging on the ground when not in use, improves safety and reduces wear on the electric wire.

[0023] Specifically, all motors in this invention use stepper motors, and the charging pile 11 has a built-in PLC controller. The PLC controller controls the rotation angle of the motor output shaft. This invention uses a binocular camera 23 to identify the charging interface, rubber plug 213, and charging compartment cover to obtain location information.

[0024] The working principle of this invention is as follows: The motor is controlled by PLC to rotate the rotating base 12, which in turn drives the first rotating arm 13 to rotate around the bracket 14, and drives the second rotating arm 18 to rotate around one end of the first rotating arm 13. The second motor 182 is started, which drives the screw 183 to rotate, so that the telescopic arm 19 on it moves telescopically along the second rotating arm 18, thereby driving the charging mechanism to move telescopically. The rotating seat 12, rotating first rotating arm 13, and rotating second rotating arm 18 are used to initially control the charging connector 25 to approach the charging compartment of the electric vehicle. The telescopic arm 19 drives the charging mechanism to approach the charging compartment further, controlling the rotating plate 24 to rotate so that one side of the protrusion 211 faces the charging compartment cover. The first motor 28 drives the lead screw 29 to rotate, thereby pushing the push plate 210 to move, which in turn moves the protrusion 211. The outer material of the protrusion 211 is rubber. By pressing the electric vehicle charging compartment cover with the protrusion 211, the cover is opened. The rotating plate 24 is controlled to rotate so that the end of the clamping plate 212 is locked inside the pull plate of the rubber plug 213. At this time, the first motor 28 is started. The push plate 210 is moved, causing the protrusion 211 to insert into the groove on the rubber plug 213. The push plate 210 and the clamping plate 212 press the pull plate of the rubber plug 213 to fix the rubber plug 213. The rubber plug 213 is pulled out by controlling the movement of the charging mechanism. After completion, the rotating plate 24 is rotated so that the charging connector 25 faces the charging compartment. The charging mechanism is moved by controlling the main body mechanism so that the charging connector 25 is inserted into the charging interface. After charging is completed, the charging connector 25 is pulled out and the rotating plate 24 is rotated so that the rubber plug 213 is reinserted into the charging interface. The protrusion 211 pushes and presses the electric vehicle charging compartment cover to complete the charging.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
