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 flexible circuit tension keeping device mountable on an electronic device includes a base seat having opposite first and second surfaces such that a flexible circuit board is bent to surround the first and second surfaces, at least one sliding member slidably disposed on the base seat in a front-rear direction, and spring members disposed between the base seat and the sliding member. The sliding member has a tense surface which is engaged with the flexible circuit board such that a pulling force generated as a result of rotation of a second device part relative to a first device part of the electronic device is applied to the flexible circuit board to move the tense surface of the sliding member toward the base seat, and the sliding member is biased by the spring members to keep tense of the flexible circuit board.

Abstract: A displaceable rotating shaft structure and a foldable device having the rotating shaft structure are disclosed. The displaceable rotating shaft structure comprises a support, a rotating shaft, a connecting rod assembly, a guide assembly, and a torsion assembly. The support has a supporting portion. The connecting rod assembly has a first outer end that is rotatably connected to the linking section of the rotating shaft and a second outer end that is pivotally connected to the supporting portion. The guide assembly has a guide rod. The guide rod is configured to displace relative to the supporting portion. When the rotating shaft is rotated, the rotating shaft drives the connecting rod assembly to adjust the angle and the total length of a joint of connecting rods of the connecting rod assembly, a distance between the rotating shaft and the support is changed through the guide assembly.
