New description: • [New technical field] This creation is about the innovative design of a hinge used in a folding electronic device, especially when the pivoting device has more torque to support the display screen at the working angle. Two-stage torque automatic closing type hinge. [Prior Art] • In a folding electronic device, for example, a notebook computer is often composed of a display screen portion and a body portion (for example, a keyboard portion), and the display screen portion is rotatable relative to the body portion. When the display portion is rotated, it is necessary to have a hinge connection so that the display screen portion is turned on or closed relative to the body portion centering on the hinge. In the prior art, the pivot mechanism is provided with a pair of concave wheels and cams on the non-circular shaft portion of the rotating shaft, and the concave portion and the convex portion of the cam and the cam are used, so that the hinge has the function of automatically closing, for example, applying The person's towel, the Republic of China, the new announcement number to help "have a pivot with automatic closing»-M function" and M302237 "multi-claw automatic locking hinge" and other previous cases, also, can be used for money-seeking type paste money MM The front case of the "like-like hybrid". The general hub provides the torque for the job. When the limb is tested, it is fixed. That is to say, the user must use the same force to turn the screen to open and close. If Yum provides too much torque for the job, the shirt (4) is turned on; on the contrary, if the torque is too small, the skeleton (4) is broken or fallen. Recently, due to the evolution of the computer operating system, such as Windows 7, in the notebook computer 3 M370286 direct touch-sensitive display of the county to facilitate the operation of the financial, is a possible trend of future development, therefore # necessary to create a two-stage The type of torsion hinge makes the screen curtain have a large cutting force when the operating angle is opened.
