Abstract: A single-axis hinge includes a base, a movable plate, a limiting block, a rotating shaft and a stand set. The base includes a first shaft mounting hole, a stand drive shaft mounting hole and a path. The movable plate is formed with a second shaft mounting hole and a limiting notch. The limiting block is installed in the path. The rotating shaft passes through the first and second shaft mounting holes and includes a driving block and a first cam. An edge of the driving block is formed with a transmission teeth portion not completely surround the edge. The stand set includes a stand drive shaft disposed in the stand drive shaft mounting hole, and a support stand driven by the stand drive shaft. The stand drive shaft includes a gear and a second cam formed with a positioning notch.

Abstract: A hinge unit includes a coupler plate formed with first and second coupler holes; first and second axles extending rotatably through the coupler holes in the coupler plate and formed with first and second engaging grooves corresponding to each other; a driving slide block disposed between the first and second axles, having first and second contact surfaces formed with first and second engagement ribs in engagement with the first and the second engaging grooves such that the slide block is movable along axes of the axles; and a positioning plate formed with first and second position holes permitting extension of the first and second axles, thereby restricting a movable range of the slide block between the coupler plate and the positioning plate. Movement of the slide block along the axes of the axles results in simultaneous rotation of the axles in directions opposite to each other.

Abstract: A dual leaf portable electronic device includes a base member having hinges mounted in a frame shell thereof, a top cover including a bracket and a display screen pivotally coupled to the bracket and having positioning holes on a bottom side thereof and respectively aimed at respective locating holes on the bracket, and positioning devices each including a movable latch having a coupling base pivotally coupled to one respective hinge at an eccentric location and a latch body extended from the coupling base and insertable through one respective locating hole of the bracket into one respective positioning hole of the display screen to lock the display screen to unlock the display screen from the bracket.

Abstract: A planetary type dual-shaft hinge includes a female shaft member, a male shaft set rotatably inserted through the female shaft member, and a transmission mechanism including a first transmission member and a second transmission member respectively affixed to the first shaft and the second shaft, and a link coupled between the first transmission member and the second transmission member. The two pivoting points between the link and the first and second transmission members are respectively deviated from the two connection points between the first and second transmission member and the first and second shaft, so that when the hinge is used in a flip-up electronic apparatus and the cover member of the electronic apparatus is opened from the base member thereof, the first shank can be turned about the second shaft, smoothening the relative movement between the cover member and the base member.
