Abstract: An electronic apparatus includes a first assembly and a second assembly. The first assembly includes at least one hook and at least one elastic locating member. The second assembly includes at least one hook groove and at least one locating groove. The second assembly receives the hook of the first assembly by the hook groove along a first assembling direction. The second assembly makes the hook engaged to the hook groove along a second assembling direction. When the second assembly moves relative to the first assembly along the second assembling direction, the elastic locating member gets into the locating groove, thereby fastening the first assembly and the second assembly.

Abstract: An electronic device is provided, which includes a bottom casing, an electronic module, at least a positioning part and an upper cover. The electronic module is disposed in the bottom casing. The positioning part is connected to the electronic module. The upper cover includes a cover body and a positioning portion. The cover body is assembled to the bottom casing. The positioning portion is connected to the cover body. A structural interference between the positioning portion and the positioning part makes the electronic module positioned. In addition, an assembling method of electronic module and a disassembling method of electronic module are also provided.

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.

Abstract: A pin-jointed structure connected between a cover member and a base member of a mobile electronic device is disclosed to include a pivot holder affixed to the base member, a mounting plate affixed to the cover member and pivoted to the pivot holder, and a spring plate connected between the mounting plate and a boss of the cover member for buffering the drawing force between the pivot holder and the mounting plate to prevent breaking of the boss of the cover member when the cover member is opening from or closing on the base member.

Abstract: A hinge structure set between a first casing and a second casing of a foldable apparatus such that the first casing is capable of being rotated relative to the second casing is provided. The foldable apparatus has a cable that extends from the inside of the first casing to the inside of the second casing by passing through the hinge structure. The hinge structure includes a hinge member and a supporting member. The hinge member is connected to the first casing. The supporting member is connected between the hinge member and the second casing, and has a cable channel that extends from the inside of the second casing to the outside thereof by passing through a through hole of the second casing for receiving a section of the cable. The cable can pass through the hinge structure so that the volume of the foldable apparatus using the same is decreased.

Abstract: A protection device is disposed between the socket entrance of the expansion socket of the expansion device and the casing of a portable computer. The casing is formed with a window corresponding to the socket entrance. In an unprotected state, the expansion device functions in a normal manner. However, in a protected state, the protection device shields the socket entrance of the expansion socket and prevents an external article from being inserted into or withdrawn from the expansion socket.
