With the advancement and development of technology, consumers are paying more and more attention to the flexibility and convenience of the cap-type portable electronic device. Nowadays, a general cover type electronic device (such as a notebook computer) has a hinge (Hinge) between the body of the electronic device and the screen to provide the best screen for the consumer when the user is opened or closed relative to the electronic device body. Flexible and easy to carry, the clamshell portable electronic device pursues minimization and strives to provide consumers with maximum convenience.

Related applications for biaxial hinges have been disclosed in TW M539211 and other patents. The biaxial hinge disclosed in the patent mainly comprises a crimping plate, a first pivot, a second pivot, an upper fixing piece and a lower fixing piece. Connecting the first pivot to the pressure plate, the second pivot is disposed parallel to the first pivot and connected to the pressure plate, and the first pivot can perform a rotation stroke relative to the second pivot The upper fixing piece is connected to the first pivot shaft and disposed away from the pressing plate. The lower fixing piece is connected to the second pivot shaft and disposed away from the pressing plate. The upper fixing piece has The upper fixing piece is subjected to a displacement stroke relative to the lower fixing piece when the first pivot performs the rotating stroke. However, the biaxial hinge can only provide the opening function, but does not have the function of pushing an external structure (such as a sub-screen or a keyboard of an electronic device), so that the electronic device needs to be larger. The volume is more functional, and the purpose of minimizing the volume after the folding of the portable electronic device is violated, causing inconvenience to the consumer and providing a more convenient user experience.

The first rotating shaft 12 is mounted on the mounting bracket 11 and the first The second rotating shaft 13 is mounted on the mounting bracket 11 and is coupled to the second component. The transmission gear 14 is disposed between the first rotating shaft 12 and the second rotating shaft 13. Further, the mounting The frame 11 is arranged such that the first rotating shaft 12 is arranged in parallel with the second rotating shaft 13, the first rotating shaft 12 has a first gear 121 meshing with the transmission gear 14, and the second rotating shaft 13 has a meshing engagement with the transmission gear 14. The second gear 131 has a pair of first cams 111 that should be disposed on the second rotating shaft 13.

Furthermore, the biaxial driving assembly 10 includes a torsion generating member 15 disposed on the second rotating shaft 13 and a reinforcing sheet 16 provided with the first rotating shaft 12 and the second rotating shaft 13, and the reinforcing sheet 16 strengthens the The mounting bracket 11 securely connects the first rotating shaft 12 and the second rotating shaft 13. On the other hand, the lateral driving assembly 20 has a second cam 21, a driving arm 22, and a spring 23. The second cam 21 is disposed on the second rotating shaft 13 and is disposed on the first cam 111. 22 is connected to the second cam 21, and the spring 23 is disposed at the The second rotating shaft 13 is on the second rotating shaft 13 and abuts against the second cam 21.
