Abstract: An FPC/FFC tension keeping device is adapted to be mounted to an electronic apparatus, and includes a tension keeping unit that includes a base seat module and a sliding module. The base seat module includes a base seat and two guide members. The base seat has two guiding slots. The guide members are respectively inserted in the guiding slots and fixedly connected to the base seat. The sliding module includes a sliding member and two resilient members. The sliding member is slidably connected to the guide members. The resilient members are respectively disposed in the two guiding slots and are respectively sleeved on the guide members. The resilient members are configured to maintain, during movement of the sliding member, contact between the sliding member and an FPC/FFC board of the electronic apparatus that wraps around the sliding member, and to conserve tension of the FPC/FFC board.

Abstract: A hinge includes a rotating shaft, two pivoting parts, and a seat. The rotating shaft includes a friction section and a protruding section coaxially extending from the friction section. Each of the pivoting parts includes a connecting piece and a sleeve piece. Each sleeve piece is extended from an edge side of the corresponding connecting piece, and bent and wrapped to form a sleeve hole. Each sleeve piece is configured to be sleeved on the friction section, and the two sleeve pieces on the peripheral surface of the friction section are bent and wrapped in different directions respectively. The seat includes a shaft hole. The friction section and the sleeve pieces are jointly arranged in the shaft hole, the connecting piece is fixed on the seat, and the protruding section protrudes out of the seat.

Abstract: A hinge includes a base frame unit and a rotating unit. The base frame unit includes a base seat having two rotating recesses and a transmitting recess, and two interfering plates respectively disposed in the rotating recesses. The rotating unit includes two rotating members respectively and rotatably disposed in the rotating recesses, and a bevel gear member disposed in the transmitting recess. Each rotating member frictionally interferes with the respective interfering plate, and has a bevel gear portion meshing with the bevel gear member. A torque generated as a result of rotation of one rotating member is transmitted through the bevel gear member to rotate the other rotating member relative to the base seat so as to make stable synchronous rotation of the rotating members.

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.

Abstract: A hinge is mountable between two casing parts of a flexible electronic device, and includes a base seat and two rotating modules disposed at two sides of the base seat for respectively mounting the casing parts thereon. Each rotating module includes a primary support plate pivotably connected to the base seat, and a secondary support plate pivotably connected to the primary support plate. When the rotating modules are rotated from an initial position, where the secondary support plates are flush with the primary support plates for resting and supporting a flexible display thereon, to a terminal position, where the secondary support plates are turned away to provide a leeway, the casing parts are shifted from an unfolded state to a folded state.
