Title:
ELECTRONIC DEVICE AND METHOD FOR CONTROLLING FOLDING AND UNFOLDING OF SCREEN OF ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005477
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide an electronic device and a method for controlling folding and unfolding of the screen of an electronic device. Two sides of a body (10) of an electronic device (100) are a first body side (11) and a second body side (12); a flexible screen (20) is wound on the body (10) from the first body side (11); the flexible screen (20) has a first screen side (21) and a second screen side (22); the first screen side (21) is on the front of the body (10), and the second screen side (22) is on the back of the body (10). A main shaft (30) is rotatably disposed on the body (10), and a driver (31A) is connected to the main shaft (30). An energy accumulator (40) is disposed on the body (10) and has a telescopic rod (41); one end of the telescopic rod (41) is connected to the first screen side (21) of the flexible screen (20); the energy accumulator (40) drives the telescopic rod (41) to move in a direction away from the first body side (11) when energy is released. One end of a first rope body (331) is connected to the second screen side (22), and the other end is wound on the main shaft (30). One end of a second rope body (332) is connected to the telescopic rod (41), and the other end is wound on the main shaft (30). A control valve (32A) is connected to the main shaft (30). The electronic device (100) can effectively reduce the probability that the driver (31A) is stuck (for example, a motor is blocked) and save power, and can reduce the probability of screen scrolling and screen bulging.
