Abstract: A locking device disposed on a casing and suitable for buckling up with a detachable object is provided. The locking device includes a base, an actuating element, and a driven latch. The base has a body fixed at the casing and a first slide track passing through the body. The actuating element has a first sliding block passing through the body and moves between a first position and a second position along a first axis via the first sliding block slidingly connected to the first slide track. The driven latch is slidingly disposed at the base and slides between a third position and a fourth position along a second axis. The driven latch and the actuating element are located at two opposite sides of the base. The driven latch has a second slide track and a locking portion. The first sliding block is slidingly connected to the second slide track.

Abstract: An electronic apparatus includes an upper cover, a lower cover, a circuit board, and a bracket. The upper cover includes a first boss. The lower cover includes a second boss. The bracket includes a first fixing plate and a second fixing plate that are connected to each other. The first fixing plate is clamped between the first boss and the second boss. The second fixing plate tilts at an angle relative to the first fixing plate. The circuit board and the second fixing plate are fixed to each other in a parallel manner.

Abstract: A foldable electronic device includes a first body and a second body, in which the second body is pivoted to the first body. The second body includes a display cover, a display module, at least one battery module and a pivot mechanism. The display cover has a display region and a battery cavity, in which the display region is adjacent to the battery cavity and the display module is installed to the display region of the display cover. The battery module is disposed in the battery cavity. The pivot mechanism is disposed between the first body and the second body and adjacent to the side wall of the battery cavity to make the second body rotate relatively to the first body on a pivoting axis.
