Title:
HINGE MECHANISM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/143738
Kind Code:
A1
Abstract:
A hinge mechanism. Two rotating supporting mechanisms (200) are respectively connected to two opposite sides of a hinge base (100); the two rotating supporting mechanisms (200) can rotate with respect to each other, so that the hinge mechanism can be switched between a first folded state and a second folded state; each rotating supporting mechanism (200) comprises a rotating shaft (210), a hinge rotating plate (220), and a hinge moving plate (230); the rotating shaft (210) is rotatably provided on the hinge base (100); the hinge rotating plate (220) is rotatably connected to the hinge base (100) by means of the rotating shaft (210); a first end of the hinge rotating plate (220) close to the rotating shaft (210) is provided with an accommodating recess (221), and a second end of the hinge rotating plate (220) distant from the rotating shaft (210) is a first supporting portion (222); the rotating shaft (210) is provided with a speed reducer (240); the speed reducer (240) is provided with a rotating output portion (241); the rotating output portion (241) can rotate along with the rotating shaft (210); the hinge moving plate (230) comprises a second supporting portion (231); the second supporting portion (231) is at least partially located in the accommodating recess (221). The above solution can solve the problem that existing electronic devices are prone to folds or breakage of the flexible screen when inwardly folded. Also disclosed is an electronic device.
