Therefore, the present invention The linking member 12, the first transmission portion 131 of the first rotating shaft 13, and the second transmission portion 141 of the second rotating shaft 14 are intermeshing gear structures.

Referring to FIG. 3-1 to FIG. 3-6, in the embodiment, the three-axis hinges are rotated to apply a plurality of points of force, and one of the functions of the first rotating shaft 13 is applied by the user. The axis hinge is actuated, and the second is for the user to apply the force to the third shaft 16 to actuate the three-axis hinge. However, the present invention specifically illustrates the rotation of the three-axis hinge. Here, only the second embodiment described above is exemplified. The first assembly section 133 of the first rotating shaft 13 is further pivotally connected to the first portion 20 of the electronic device, and the second assembly segment 163 of the third rotating shaft 16 is initially formed in the embodiment. The second portion 21 of the electronic device is pivotally connected. In addition, the second portion 21 of the electronic device is further assembled or disassembled relative to the second portion 21. The three portions 22, and the third portion 22 can be a flat panel display. When the user wants to open the second portion 21 of the electronic device relative to the first portion 20, the user first applies a second portion 21 to the second portion 21 toward a force that is displaced away from the first portion 20, and the second portion 21 drives the third shaft 16 to rotate in a corresponding direction to perform the rotation stroke, so that the second portion 21 is opposite to the first portion Portion 20 has an opening angle. However, when the second portion 21 continues to drive the third rotating shaft 16 to perform the rotating stroke, the second cam 161 of the third rotating shaft 16 continues to generate relative rotation, but when the second portion 21 is opposite to the first portion When the portion 20 is opened by a predetermined angle, the second cam 161 touches the second positioning portion 154 of the second support frame 15 to limit the rotation of the third rotating shaft 16 to the second portion. 21 is fixed at the predetermined angle with respect to the first portion 20, and its implementation is as shown in FIGS. 3-1 to 3-2. Further, when the third rotating shaft 16 performs the turning stroke, the second cam 161 of the third rotating shaft 16 is pushed against the locking member 17 located in the limiting rail 155 toward the second rotating shaft 14 In addition, the first cam 142 on the second rotating shaft 14 is restricted by the locking member 17. In addition, during the above rotation of the present creation, the first cam 142 of the second rotating shaft 14 is normally abutted. The second rotating shaft 14 is simultaneously restricted by the locking member 17 and the first positioning portion 153 by the first positioning portion 153 of the second support frame 15 . Therefore, during the flipping process illustrated in the drawings 3-1 to 3-2, the second rotating shaft 14 does not rotate.

Referring to FIG. 3-2 and FIG. 3-3, when the user opens the second portion 21 at an angle with respect to the first portion 20, the second portion 21 is to be overlapped with the first portion. The user further applies a force to the second portion 21 to displace the second portion 21 toward the first portion. The third rotating shaft 16 is driven by the second portion 21 to perform the turning stroke again. The second portion 21 is superimposed on the first portion 20, as shown in FIG. 3-1. Furthermore, in the implementation process illustrated in FIG. 3-2, the user may disassemble the third portion 22 of the electronic device relative to the second portion 21 before flipping, and then the second portion The portion 21 applies a force to cause the second portion 21 to overlap the first portion. More specifically, in the flipping process depicted in FIG. 3-2 and FIG. 3-3, the third rotating shaft 16 performs the turning stroke again, so that the second cam 161 is reversed from the rotating direction in FIG. 3-1. . However, during the inversion stroke, one end of the second cam 161 abuts against the second positioning portion 154, so that the third rotating shaft 16 is restricted by the second positioning portion 154 and cannot continue. As shown in Figure 3-4. Then, the user further applies a force to the second portion 21 to be more specifically stacked on the first portion 20. The user continues to apply the second portion 21 toward the first portion. The directional displacement force causes the third rotating shaft 16 to move toward the first rotating shaft 13 and simultaneously drives the second rotating shaft 14 to generate the second turning stroke of the corresponding rotating direction, so that the second rotating shaft 14 The second transmission portion 141 is also rotated to drive the linkage member 12 to rotate. As can be seen from the foregoing, the linkage member 12 and the first transmission portion 131 of the first rotating shaft 13 are engaged with each other, so that the linkage member 12 receives During the driving of the second transmission portion 141, the first transmission portion 131 of the first rotating shaft 13 is synchronously rotated, and the first rotating shaft 13 is caused to perform the first turning stroke until the second portion 21 is The first part 20 is close together, and its aspect is as shown in Figure 3-5.

Referring to FIG. 3-5 to FIG. 3-6, in an embodiment, when the user wants to open the first portion 20 and the second portion 21 of the electronic device that are closed close to each other, the third portion is first The rotating shaft 16 applies a force for moving the third rotating shaft 16 away from the first rotating shaft 13 to displace the second portion 21 away from the first portion 20, and drives the second rotating shaft 14 to generate the same direction. Rotating, the second rotating shaft 14 performs the second turning stroke, and the linking member 12 is rotated, and the linking member 12 simultaneously drives the first transmission portion 131 of the first rotating shaft 13 to rotate, so that the first rotating shaft 13 is rotated. The first turning stroke rotates in a direction away from the second rotating shaft 14. However, during the rotation of the first rotating shaft 13, the first cam 142 abuts against the first positioning portion 153 of the second supporting frame 15, thereby restricting the first rotating shaft 13 from continuing to rotate. Moreover, after the rotation process is completed, the user can continue to flip the second portion 21 away from the first portion 20 according to the implementation requirements of the user, so that the three-axis hinge of the present creation is generated as shown in FIG. The aspect shown in Fig. 2-1 can also continue the flip mode of the three-axis hinge as shown in Figure 3-1.

In summary, the three-axis hinge of the same opening and closing device uses the linkage to make the first rotating shaft and the second rotating shaft have the same dynamic relationship, and the third rotating shaft is used to enable the creation of the creation to be opened at a large angle. The problem of the three-axis structure used in the conventional electronic device is specifically solved.

The above description has been made in detail, but the above is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the creation of the creation, that is, the equality of the patent application scope according to the present creation. Changes and modifications are still covered by the patents of this creation.
