Abstract

The present disclosure discloses a charging station, an intelligent robot, and a charging system. The charging station includes a control chip, a charging apparatus, and a differential positioning apparatus. The charging apparatus is electrically connected to the control chip, and the differential positioning apparatus is communicatively connected to the control chip, where the control chip is configured to receive first observation information and position information of the charging station sent by the differential positioning apparatus, and send the first observation information and the position information to an intelligent robot, and configured to control the charging apparatus to charge the intelligent robot.

Claims (33)

1 . A charging station, comprising:

a control chip;

a charging apparatus electrically connected to the control chip; and

a differential positioning apparatus communicatively connected to the control chip;

wherein the control chip is configured to receive first observation information and position information of the charging station sent by the differential positioning apparatus, and send the first observation information and the position information to an intelligent robot, and configured to control the charging apparatus to charge the intelligent robot;

wherein the charging station further comprises a mounting seat, the charging apparatus is arranged on a first side face of the mounting seat, and the control chip is arranged on a second side face of the mounting seat opposing the first side face.

2 . The charging station according to claim 1 ,

wherein the differential positioning apparatus is arranged on top of the mounting seat.

3 . The charging station according to claim 2 , wherein the charging station further comprises:

a base plate; and

a hood body connected to the base plate, wherein an accommodating space is defined between the hood body and the base plate, and the mounting seat is located within the accommodating space.

4 . The charging station according to claim 3 , wherein the mounting seat has cross sectional areas gradually increasing from top to bottom, and the hood body has cross sectional areas gradually increasing from top to bottom.

5 . The charging station according to claim 2 , wherein a positioning interface is provided in a lower part of the charging station, the positioning interface is electrically connected to the control chip, and the positioning interface is connected to a solenoid coil.

6 . The charging station according to claim 2 , wherein the charging apparatus comprises a wireless charging coil.

7 . The charging station according to claim 2 , wherein the charging apparatus comprises a charging interface or charging wire arranged on the mounting seat.

8 . The charging station according to claim 1 , wherein a power source is provided within the charging station, and the charging apparatus and the differential positioning apparatus are electrically connected to the power source.

9 . The charging station according to claim 1 , wherein a positioning interface is provided in a lower part of the charging station, the positioning interface is electrically connected to the control chip, and the positioning interface is connected to a solenoid coil.

10 . The charging station according to claim 1 , wherein the charging apparatus comprises a wireless charging coil.

11 . The charging station according to claim 1 , wherein the charging apparatus comprises a charging interface or charging wire arranged on the mounting seat.

12 . The charging station according to claim 1 , wherein the differential positioning apparatus comprises a GPS antenna.

13 . The charging station according to claim 1 , wherein the charging apparatus comprises a wireless charging coil, and the differential positioning apparatus comprises a GPS antenna, the GPS antenna being configured to: receive the first observation information and the position information of the charging station, and send the first observation information and the position information to the control chip such that the control chip sends the first observation information and the position information to the intelligent robot, and the wireless charging coil being configured to generate an electromagnetic signal based on information on charging of the intelligent robot sent by the control chip such that a receiving terminal coil provided within the intelligent robot senses the electromagnetic signal to generate a current to charge the intelligent robot.

14 . The charging station according to claim 13 , wherein the charging apparatus comprises a charging circuit, and the GPS antenna comprises a positioning circuit.

15 . The charging station according to claim 13 , wherein a power source is provided within the charging station, and the charging apparatus and the differential positioning apparatus are electrically connected to the power source.

16 . The charging station according to claim 15 , wherein the wireless charging coil is electrically connected to the power source.

17 . An intelligent robot, configured to receive first observation information and position information of the charging station according to claim 1 , and second observation information of the intelligent robot, compare the first observation information with the second observation information to obtain a corrected value, and correct position information of the intelligent robot based on the corrected value.

18 . A charging system, comprising:

an intelligent robot; and

the charging station according to claim 1 , wherein

the charging apparatus is configured to charge the intelligent robot,

the differential positioning apparatus is configured to receive first observation information and position information of the charging station, and send the position information and the first observation information to the control chip;

the control chip is configured to send the received position information and the received first observation information to the intelligent robot; and
