Title:
ROTATING SHAFT APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/267484
Kind Code:
A1
Abstract:
A rotating shaft apparatus (40), comprising an adaptor (41), a shaft core (42), and a slider-crank mechanism (43). The adaptor is fixedly connected to a load; the shaft core is fixedly connected to the adaptor; the slider-crank mechanism acts on the shaft core to provide torque; the torque partially or completely counteracts the gravity torque of the load; pressure springs (434) are provided in the slider-crank mechanism; the elastic force of the pressure springs acts on the shaft core, and the elastic force is changed along with rotation of the shaft core; it is ensured that the torque of the shaft core counteracts the gravity torque of the load in the rotating process of the shaft core, such that a load pitching operation is easy and convenient; and meanwhile, the space occupied by the rotating device is reduced, so as to satisfy light and thin requirements of the load after mounting the rotating shaft device.
