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 first fixing bracket, a shaft and a swivel bracket. The first fixing bracket includes two first support pieces and a first connection piece. The two first support pieces are arranged in parallel to each other, and the first connection piece is connected to the two second support pieces. The two first support pieces are respectively provided with a shaft hole and the shaft holes are arranged coaxially along a central axis. At least one of the first support pieces is provided with one limiting extension portion extending in a direction in parallel to the central axis at an upper front end of the first support piece and extending towards the other first support piece. The shaft is inserted into the shaft hole. The swivel bracket includes a mounting plate; an extension plate extending from a bottom edge of the mounting plate and bent towards a side corresponding to the inner surface of the mounting plate; at least one sleeve piece located between the two first support pieces, extending from an end of the extension plate away from the bottom edge, and bent and wound towards the side corresponding to the inner surface. The sleeve piece is configured to be sleeved over the shaft, such that the swivel bracket can rotate with respect to the first fixing bracket. When the swivel bracket is flipped outwards with respect to the first fixing bracket, the extension plate moves towards the limiting extension portion.

Abstract: A hinge includes a seat, a shaft, a swivel bracket and at least one limiting bar. The seat includes two support portions. An accommodation area is defined between the two support portions. The two support portions are respectively provided with a shaft hole. The two shaft holes are arranged coaxially and connected to the accommodation area. The shaft includes a coupling section and two pivoting sections. The coupling section is located between the two pivoting sections. The two pivoting sections are respectively provided in one of the two shaft holes in a rotatable manner, and the coupling section is in the accommodation area. The swivel bracket includes a mounting plate, a sleeve piece and at least one extension portion. The mounting plate includes an inner surface, an outer surface, and a bottom edge. The sleeve piece extends from the bottom edge of the mounting plate and is wound at a side corresponding to the inner surface. The sleeve piece is configured to be sleeved over and fixed to the coupling section, such that swivel bracket is fixed to the shaft and rotatable with respect to the seat to move the inner surface to face the accommodation area. The extension portion is adjacent to lateral edges of the sleeve piece and extends from the bottom edge and is bent towards the side corresponding to the inner surface. The limiting bar is disposed on one of the two support portions and is in the accommodation area. The limiting bar is in a rotational path of the extension portion. When the swivel bracket is flipped outward with respect to the seat, the extension portion moves towards the limiting bar.

Abstract: The present invention relates to a liquid cooling system with water quality monitoring, which comprises a first inlet, a first outlet, a heat exchange unit, a sensing unit, and a control unit connected to the sensing unit and a first pump. The heat exchange unit has a heat exchanger connected to the first inlet and the first pump connected to the first outlet and the heat exchanger. The first pump is used to drive a first working liquid after heat exchange in the heat exchanger. The sensing unit senses a pH value of a first working liquid to generate a sense signal. The control unit compares the sense signal with a preset pH range to generate a compared result which is sent to an external interface. By means of the design of the present invention, the pH value of water can be monitored.

Abstract: A hinge includes two guide frames spaced apart from each other in a front-rear direction, a transmitting assembly interposed between the guide frames, a frictional torque generating assembly having two opposite thrust plates, and two rotary brackets disposed opposite to each other. Each rotary bracket includes an arcuate pivot portion pivotably connected with the respective guide frame, an actuating portion coupled with the transmitting assembly to actuate the transmitting assembly, and a frictional surface in frictional contact with the respective thrust plate to bring synchronous rotations of the arcuate pivot portion, the actuating portion and the frictional surface, and to make synchronous and opposite rotations of the rotary brackets.

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 multi-position hinge includes a base seat, a first axle, a second axle and a sliding assembly. The first and second axles rotatably extend through the base seat in a first direction and are spaced apart from each other in a second direction. The first axle has a first recess, a second recess and a first gear portion. The second axle has a third recess, a fourth recess and a second gear portion corresponding with the first recess, the second recess and the first gear portion, respectively. The sliding assembly includes a first sliding member engageable with the first and third recesses, and a second sliding member engageable with the second and fourth recesses. The first and second axles are rotatable in turn and then rotated synchronously to perform multi-position shifting.

Abstract: A hinge is connectable with two housing parts to allow opening and closing of the housing parts. The hinge includes a mounting seat and two rotary units. The mounting seat has a central recessed portion. The rotary units are connected with the mounting seat and shiftable between an unfolded state and a folded state. Each rotary units includes a linking member, a rail sliding block, a rotating bracket and a cover plate. During the shifting from the unfolded state to the folded state, the rail sliding block is slid relative to both the linking member and the rotating bracket and is turned relative to the mounting seat. In the folded state, the cover plates are inclined to each other in a direction away from the mounting seat to cooperate with the central recessed portion to form a space for receiving a bending portion of a flexible display.
