US Patent 10470564 Support device

A support device adapted to support an electronic device is provided. The electronic device has a display surface. The support device includes a base, a support frame, and at least one torque fixing assembly. The base includes a first arc surface portion. The support frame includes a second arc surface portion opposite to the first arc surface portion and an axis. The support frame rotates along the axis such that the second arc surface portion slides relative to the first arc surface portion and the electronic device switches between a first use state and a second use state. The torque fixing assembly is disposed at the first arc surface portion and the second arc surface portion. When the second arc surface portion slides relative to the first arc surface portion, the second arc surface portion rubs against the torque fixing assembly and torque is generated.
