This application provides a wireless charging system. The wireless charging system has the function of wirelessly charging an electronic stylus while receiving the electronic stylus. The wireless charging system includes a tablet computer, a wireless keyboard, and an electronic stylus. The wireless keyboard includes a keyboard body, a bracket for placing the tablet computer, and a connecting portion for movably connecting the keyboard body and the bracket. The tablet computer is provided with a first wireless charging sending device. The wireless keyboard is provided with a first wireless charging receiving device. The first wireless charging receiving device receives an electromagnetic signal sent by the first wireless charging sending device. The connecting portion includes a receiving cavity provided with an opening at an end and a second wireless charging sending device. The second wireless charging sending device is configured to wirelessly charge the electronic stylus received in the receiving cavity.

Wireless charging system

A terminal device includes: a tablet and a keyboard. The tablet includes: a first controller, a first charging port, and a battery. The keyboard includes: a second controller and a second charging port; and the keyboard includes no battery. The first controller communicates with the second controller through data lines in 3pin. When the first charging port is connected to a first external power supply, and the second charging port is connected to a second external power supply, when a charging power of the first charging port is greater than a charging power of the second charging port, the first charging port is selected to charge the tablet and power is supplied to the keyboard through a power line in the 3pin; otherwise, the second charging port is selected to supply power to the keyboard and the tablet is charged through a power line in the 3pin.

Terminal device and charging method

A system for detecting proper positioning of an accessory, including an electronic device and an accessory. The electronic device includes a first attachment component, a magnetometer, and a processor. The accessory includes a second attachment component. The second attachment component is configured to be attached to the first attachment component, so that the accessory is fixed through attachment to the electronic device in a first orientation or a second orientation. The magnetometer is further configured to be triggered by a combined magnetic field of the first attachment component and the second attachment component to output the magnetic field intensity information when the accessory is fixed through attachment to the electronic device in the first orientation or the second orientation. The processor indicates whether the accessory is fixed in position based on the magnetic field intensity information.
