Abstract: A hinge device for connecting first and second objects includes a base seat and a sliding member slidably connected to the base seat through a coupling member to be turned about a rotating axis between folded and unfolded states. In the folded state, first and second object connecting sections of the base seat and the sliding member are disposed at two opposite sides of a mounting section of the base seat to allow folding of the objects to each other. In the unfolded state, the second object connecting section is placed above the first object connecting section to allow the second object to be unfolded and inclined to the first object.

Abstract: A dual-shaft driving module includes two shafts and a synchronizing block sandwiched between the two shafts. The two shafts are substantially parallel to each other and are substantially in a mirror symmetrical arrangement. Each shaft has two spiral grooves recessed on an outer surface thereof, and each spiral groove has a spiral angle within a range of 40 degrees to 60 degrees. The synchronizing block includes two concave surfaces arranged on two opposite sides thereof and four driving portions respectively protruding from the two concave surfaces. The two concave surfaces respectively face the two shafts, and each concave surface accommodates a part of the corresponding shaft. The four driving portions are respectively inserted into the four spiral grooves. When one of the two shafts is spun to transmit a force to the synchronizing block, the synchronizing block rotates the other shaft at the same time by the force.

Abstract: A hinge includes a base frame, a mechanically transmitting assembly and two support frames. The base frame defines two guideways disposed opposite to each other in a front-and-rear direction. The mechanically transmitting assembly is mounted on the base frame and partly disposed in the guideways. Each support frame has an arcuate frame body slidably engaging the respective guideway and coupled with the mechanically transmitting assembly, and a support frame body disposed outwardly of the base frame. The support frames are rotatable about a rotating axis relative to the base frame to make synchronous rotation in opposite rotational directions through the mechanically transmitting assembly. The rotating axis is disposed above the base frame.
