Referring to FIG. 2 to FIG. 10, the detailed operation mode of the biaxial hinge 100 is described, that is, an opening operation of the biaxial hinge 100 is described. In the initial state, it is assumed that the first fixing plate 21 is not opened relative to the second fixing plate 31. As shown in FIG. 3 and FIG. 4, the second convex portion 231 is in contact with the third contact surface 421, so that the rotation switching component cannot be moved up and down. The third convex portion 321 is in a latching relationship with one of the second latching regions 415, so that the second shaft 30 cannot be rotated relative to the bracket 10. At the same time, the first limiting block 16 is in contact with the first convex portion 221, and the second limiting block 17 is in contact with the fourth convex portion 331 so that the first shaft 20 and the second shaft 30 cannot face each other. In one direction, the first shaft 20 is forced to rotate in a direction away from the second shaft 30, and the second shaft 30 is restricted from rotating.

Then, the first fixing plate 21 is biased, and the first shaft 20 is rotated at an angle with respect to the bracket 10. As shown in FIG. 5 and FIG. 6, the second protrusion 231 is rotated by the first shaft 20. Separating from the third contact surface 421, the third convex portion 321 is slidably moved to the second sliding portion 416, thereby pushing the first pushing piece 41 to slide toward the first shaft 20, at the same time, The second pusher piece 42 is driven by the first pusher piece 41, and when the first pusher piece 41 continues to slide to cause a snap relationship between the first clicker region 413 and the first protrusion 221, The second shaft 30 is rotated away from the first shaft 20, and the first shaft 20 is in a latching relationship with the first latching portion 413 of the first pusher piece 41. Can't turn.

Then, when the first fixing plate 21 continues to be stressed, the first shaft 20 is rotated by an angle with respect to the second shaft 30 to drive the bracket 10 to change position, as shown in FIGS. 7 and 8. At the same time, the second shaft 30 rotates relative to the bracket 10 while the bracket 10 changes position, so that the third protrusion 321 enters the other second latching region 415 from the second slip zone 416. At this time, the first convex portion 221 can slide to the first sliding portion 414 and push the first pushing piece 41 to slide to the second shaft 30 until one of the first pushing pieces 41 The second latching region 415 has a latching relationship with the third protruding portion 321 . That is, at this point in time, the first shaft 20 is rotated relative to the bracket 10 away from the second shaft 30, and the second shaft 30 is due to one of the second latching regions 415 and the first The three convex portions 321 generate a click relationship and cannot rotate relative to the bracket 10. Finally, when the first fixing plate 21 is again stressed, the first shaft 20 will rotate another angle with respect to the bracket 10 again, as shown in FIG. 9 and FIG. 10, the external member connected to the first shaft 20 An action of rotating 180 degrees relative to the other outer member is produced. Furthermore, as can be seen from the foregoing description, the present invention causes the first shaft 20 and the second shaft 30 to rotate asynchronously when the first shaft 20 and the second shaft 30 rotate due to the action of the rotation switching assembly. Thereby, mechanical anomalies caused by synchronous rotation are avoided.

Referring to FIG. 1 to FIG. 4 , in order to reduce the friction between the first cam 22 and the second cam 23 and the bracket 10 , in an embodiment, the bracket 10 is formed with a plurality of lubricating oils respectively. The oil-containing groove 18 is disposed on the first surface 11 and the second surface 12 and is arranged in the first perforation 13 . In another embodiment, the oil containing grooves 18 may also be arranged in the second through hole 14 to reduce the friction between the third cam 32 and the fourth cam 33 and the bracket 10.

Referring to FIG. 1 to FIG. 2 , in order to limit the trajectory of the rotation switching assembly, in one embodiment, the two sides of the bracket 10 respectively form a retaining wall 19 protruding from the first surface 11 and the second surface 12 . Further, the second retaining wall 19 allows the rotary switching assembly to linearly slide between the first shaft 20 and the second shaft 30 during the opening operation, so that no offset can be generated. The rotary switching assembly can accurately limit the rotation of the first shaft 20 or the second shaft 30. Moreover, the distance between the second retaining walls 19 corresponds to the width of the first pusher piece 41 and the second pusher piece 42.

In summary, the present invention is only a preferred embodiment of the present invention. When it is not possible to limit the scope of implementation of the present invention, that is, the equal changes and modifications made by the patent application scope of the present invention should still be covered by the present patent. .
