Document Type and Number:
WIPO Patent Application WO/2020/107388
Kind Code:
A1
Abstract:
An electronic device comprises a housing and a circuit board. The housing comprises a first frame, a second frame, a display screen, and a bending angle measurement mechanism. The first frame and the second frame are rotatably connected by means of a rotary shaft. The display screen is bendable along the rotary shaft. The bending angle measurement mechanism comprises a first sound wave receiver, a second sound wave receiver and a sound wave transmitter. The first sound wave receiver and the second sound wave receiver are respectively provided at the first frame and the second frame. The sound wave transmitter is provided at the first frame or the second frame. The first sound wave receiver, the second sound wave receiver, the sound wave transmitter and a processor are electrically connected to the circuit board. The processor can calculate a bending angle between two rotatable screen sections of the display screen by means of the first sound wave receiver, the second sound wave receiver and the sound wave transmitter. Also provided are a housing of the electronic device, a bending angle measurement mechanism, and a measurement method of the bending angle measurement mechanism.
