Abstract: A foldable electronic apparatus includes a flexible display, a housing unit, and a supporting device. The supporting device includes a flexible first supporting plate, a flexible second supporting plate, and a plurality of supporting members. Each of the supporting members has a first end portion that is connected to the first supporting plate, a second end portion that is connected to the second supporting plate, and a main body portion that has two opposite sides respectively connected to the first end portion and the second end portion. The supporting device is operable to convert between a first state, in which two opposite sides of the supporting device are distal from each other, and a second state, in which the supporting device is folded along a folding axis such that the opposite sides of the supporting device are proximate to each other.

Abstract: A sliding rail device includes a first rail, a second rail and two supporting units. The first rail includes a first base wall and two first side walls cooperating with the first base wall to define a first passage. The first base wall has two engaging slots respectively adjacent to the first side walls. The second rail engages the first passage, is movable relative to the first rail, and includes a second base wall and two second side walls. The supporting units respectively and movably engage the engaging slots, and respectively and slidably abut against the first side walls and the second side walls. During movement of the second rail relative to the first rail, the supporting units are driven to respectively move along the engaging slots, and to move toward each other to tighten abutment of the supporting units against the second side walls.

Abstract: A hinge connectable with two housing parts to allow opening and closing thereof includes a mounting seat, two rotary units and two lateral support plates. The mounting seat has two first arcuate slots at two sides of a central line. The rotary units are connected with the mounting seat at the two sides of the central line for mounting the housing parts, and shiftable between an unfolded state and a folded state. Each rotary unit includes a linking member, a rail sliding block, a rotating bracket and an interposed sliding member interposed between the rail sliding block and the rotating bracket. The sliding of the rail sliding block relative to the rotating bracket can be steady and firm without the need to elongate the inclined rails of the rail sliding block and the rotating bracket, which renders the hinge more compact and slim.

Abstract: A multi-shaft pivot shaft device includes an assembled section mounted on the display module, a fixed section disposed on an apparatus body module and a drive unit (or transmission module and linking module) disposed between the assembled section and the fixed section and/or a reaction module disposed between the assembled section and drive unit. The assembled section, fixed section and the drive unit are pivotally connected with a shaft system. When the assembled section moves from an initial position to a set position, the drive unit is displaced (lowered) and/or the assembled section is moved back (to adjust the angle) so as to achieve a complex moving effect. In addition, the display module raises the apparatus body module and the display module is automatically positioned in an angle or a position for a user to easily watch.
