US Patent 11392178 Locking hinges

An example electronic device includes a display screen, a first sensor on the display screen to transmit a first signal upon being contacted, a controller to receive the first signal and transmit a second signal in response to receiving the first signal, a motor to receive the second signal to trigger an actuation motion, a hinge connected to the display screen and comprising a first locking mechanism, and a second locking mechanism aligned with the first locking mechanism. The second locking mechanism is triggered by the actuation motion of the motor, and the triggering of the second locking mechanism is to activate the first locking mechanism to control movement of the hinge and the display screen.
