[0017] The utility model will be further explained in detail in combination with the drawings and specific embodiments of the specification.

[0018] As Figure 1The first proximity switch and the second proximity switch are arranged at the bottom or one side of the positive pole piece and the negative pole piece of the charging pile respectively, and are connected to the input end of the first microprocessor of the charging pile control system. The first proximity switch and the second proximity switch can be mechanical switches or infrared switches. For example, when the two proximity switches are non-contact infrared proximity switches, the infrared proximity switch is installed on one side of the pole piece movement path, the emitter of the infrared proximity switch is aligned with the movement path of the pole piece, and the infrared proximity switch is installed at a certain distance from the starting position of the pole piece to ensure that the distance between the infrared proximity switch and the pole piece is suitable for its detection range. The output signal of the infrared proximity switch is connected to the first microprocessor. When the infrared proximity switch is triggered, it indicates that the corresponding pole piece is pressed down. By arranging the first proximity switch and the second proximity switch at the charging pile end, the robot charging end can accurately monitor whether the two pole pieces of the charging pile are pressed down correctly. In this way, the charging pile can immediately detect whether the pole pieces have been successfully contacted by the robot, avoiding the failure of charging due to poor contact.

[0019] It can be understood that the technical content disclosed in CN 222070736U is no longer described in detail, and only the newly added part is specifically described.

[0020] Specifically, at the robot end, the second communication transceiver controller is mainly responsible for the transmission and reception of communication signals. The second communication transceiver controller is connected to the communication interface of the second microprocessor of the robot control system. The robot driver is a device originally in the robot control system, which is connected to the output end of the second microprocessor, and is used to drive each part (such as the wheel) of the robot to perform corresponding actions according to the control signal of the second microprocessor.

[0021] At the charging pile end, the bottom or one side of the positive pole piece is provided with a first proximity switch for detecting whether the positive pole piece is pressed down, and the bottom or one side of the negative pole piece is provided with a second proximity switch for detecting whether the negative pole piece is pressed down. The first proximity switch and the second proximity switch are connected to the input end of the first microprocessor of the charging pile control system. The two proximity switches can be mechanical switches or infrared switches. For example: when the two proximity switches are non-contact infrared proximity switches, the infrared proximity switch is installed on one side of the pole piece movement path, and the emitter of the infrared proximity switch is aligned with the movement path of the pole piece. The infrared proximity switch is installed at a certain distance from the starting position of the pole piece to ensure that the distance between the infrared proximity switch and the pole piece is suitable for its detection range. The output signal of the infrared proximity switch is connected to the first microprocessor. When the infrared proximity switch is triggered, it indicates that the corresponding pole piece is pressed down. By arranging the first proximity switch and the second proximity switch at the charging pile end, the robot charging end can accurately monitor whether the two pole pieces of the charging pile are pressed down correctly. In this way, the charging pile can immediately detect whether the pole pieces have been successfully contacted by the robot, avoiding the failure of charging due to poor contact.

[0022] At the charging pile end, the first communication transceiver controller is connected to the communication interface of the first microprocessor, and is used to send the information of the detected pole piece being pressed down to the robot end. The second communication transceiver controller at the robot end receives the information and sends it to the second microprocessor. The second microprocessor sends a stop command to the robot driver, and the robot driver controls the robot to stop, so as to protect the equipment safety. The first communication transceiver controller and the second communication transceiver controller can be point-to-point communication devices or 4G / 5G communication modules.

[0023] At the charging pile end, the first vibration motor is connected with the positive plate, the second vibration motor is connected with the negative plate, and both vibration motors are connected with the output end of the first microprocessor. Through the vibration motor, the corresponding pole can be vibrated to clean the dirt. Both vibration motors are micro eccentric rotor motors, such as the existing eccentric rotor motor arranged in the mobile phone, the principle is that an eccentric block is installed at the rotor shaft end of the motor body, the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block is used to obtain the excitation force, the vibration motor is powered to rotate, the eccentric block on the motor shaft is driven to generate inertial excitation force, so that the whole vibration motor vibrates. At the end of the two vibration motors away from the eccentric block, that is, the end cover position, a connecting plate of non-conductive material is arranged, the vibration motor is connected with the front or back of the pole through the connecting plate, and the connecting plate is preferably an L-shaped plate, and the connection mode is preferably glued.

[0024] It can be understood that the embodiment can also share one vibration motor for two poles, that is, the vibration motor is connected with the positive plate and the negative plate through the connecting plate, and the end of the connecting plate can be divided into two branches connected with the two poles respectively.

[0025] As shown in Figure 2 , the working principle of the embodiment is:

[0026] At the charging pile end: after the initialization of the charging pile, the first proximity switch and the second proximity switch detect whether the two poles of the charging pile are pressed down by the charging end of the robot, if it is detected that the poles are pressed down, the information that the poles are pressed down is sent to the robot end through the first communication transceiver controller to inform the robot to stop. At the robot end: after the initialization of the robot, the robot is connected with the charging pile, the second communication transceiver controller waits whether the stop signal is sent from the charging pile end, if the stop signal is received, the second microprocessor controls the robot driver to make the robot stop.

[0027] Then, whether the communication can be realized is detected according to the logic in CN 222070736U, if the communication is realized, the final charging process is completed. If the robot end fails to detect the handshake signal after waiting for a period of time, after the timeout, the robot end sends the abnormal connection to the charging pile end, after receiving the abnormal connection information, the first microprocessor of the charging pile end starts the first vibration motor and the second vibration motor to vibrate and clean the two poles. The robot end continues to count, and checks whether the communication can be realized, if the handshake is successful, the process is operated according to the flow in CN 222070736U; if it still fails, the charging pile end is informed that the cleaning is timed out, and the charging pile end stops the vibration motor after receiving the cleaning abnormal information. The robot end controls the robot to retreat from the pile, reports the charging failure (here, the number of failures can be set, such as 3 times in succession), and sends an alarm to inform the personnel to handle.

[0028] To sum up, in one aspect, by setting the vibration motor, when the charging pole is contaminated, the vibration motor can effectively remove the dirt through the vibration of the pole, restore the normal contact and communication ability of the pole. Even if the contact surface of the charging pile has some debris, the vibration motor can automatically clean it, reduce the charging failure caused by contamination, ensure the continuous operation of the robot, and ensure the safety of the equipment. On the other hand, the combination of the vibration motor and the proximity switch can ensure the cleaning state of the charging pile and the docking accuracy, thereby greatly improving the success rate of the charging process, reducing damage caused by faults or misoperations, and improving the overall reliability and maintenance efficiency of the system.
