Abstract
A foldable electronic device includes a first base, a second base, a hinge, a brake, an object sensor, and a controller. The hinge pivotally connects the first base to the second base. The brake is disposed in the hinge. When the first base is expanded with respect to the second base, the object sensor senses whether an object is placed on the second base. When the object sensor senses that the object is placed on the second base, the object sensor sends out a sensed signal. The controller selectively switches on the brake in response to the sensed signal, so as to restrain a rotating angle formed by the first base and the second base.

A foldable electronic device comprising:
- a first base;
- a second base;
- a hinge pivotally connecting the first base to the second base;
- a brake disposed in the hinge;
- an object sensor selectively disposed in one of the first base and the second base;
- and
- a controller electrically connected to the brake and the object sensor;
- wherein when the first base is expanded with respect to the second base, the object sensor senses whether an object is placed on the second base;
- when the object sensor senses that the object is placed on the second base, the object sensor sends out a sensed signal;
- the controller selectively switches on the brake in response to the sensed signal, so as to restrain a rotating angle formed by the first base and the second base.
A device protection method adapted to a foldable electronic device, the foldable electronic device comprising a first base, a second base, and a brake, the device protection method comprising steps of:
- when the first base is expanded with respect to the second base, sensing whether an object is placed on the second base;
- and
- when sensing that the object is placed on the second base, selectively switching on the brake, so as to restrain a rotating angle formed by the first base and the second base.
