[0071] The slider group 4 is slidably disposed in the first accommodation space 15 and the second accommodation space 16 of the base 1 along the second direction D2 between the first rotating shaft 2 and the second rotating shaft 3. The slider group 4 includes a first slider 41 disposed in the first accommodation space 15 and correspondingly partially accommodated in the first groove 221 and / or the third groove 321, and a second slider 42 disposed in the second accommodation space 16 and correspondingly partially accommodated in the second groove 231 and / or the fourth groove 331. In detail, since the distance between the first switching member 22 and the third switching member 32 and the distance between the second switching member 23 and the fourth switching member 33 are relatively close, at least one of the two ends of the first slider 41 in the second direction D2 must be accommodated in the corresponding groove (the first groove 221, the third groove 321), and at least one of the two ends of the second slider 42 in the second direction D2 must be accommodated in the corresponding groove (the second groove 231, the fourth groove 331). In detail, in this embodiment, if the two ends of the first slider 41 are respectively accommodated in the third shallow groove portion 321b of the first groove 221 and the third groove 321, there will be no space to slide along the second direction D2. If only one end of the first slider 41 is accommodated in the third shallow groove portion 321b of the third groove 321, When the second slider 42 is in the deep groove portion 321a, there will be no space for sliding along the second direction D2. Only when the first groove 221 and the third deep groove portion 321a of the third groove 321 both face the first slider 41, the first slider 41 has space to slide along the second direction D2; if the two ends of the second slider 42 are respectively accommodated in the second groove 231 and the fourth shallow groove portion 331a of the fourth groove 331, there will be no space for sliding along the second direction D2. If only one end of the second slider 42 is accommodated in the fourth deep groove portion 331b of the fourth groove 331, there will be no space for sliding along the second direction D2. Only when the second groove 231 and the fourth deep groove portion 331b of the fourth groove 331 both face the second slider 42, the second slider 42 has space to slide along the second direction D2. When the first slider 41 and the second slider 42 have no space to slide, they will be able to lean against the inner wall surface of the corresponding groove to limit the rotation of the first shaft 2 or the second shaft 3, thereby achieving multi-stage switching. The details and steps of the multi-stage switching will be described later.

[0072] In addition, in the present embodiment, the second base body 12 of the base 1 has a plurality of limit plates 121 protruding toward the first base body 11 and the third base body 13 respectively and extending along the second direction D2, and the limit plates 121 restrict the first slider 41 and the second slider 42 to slide only in the second direction D2. In addition, the second base body 12 of the base 1 also has a slide groove 122 formed through the first direction D1 and extending along the second direction D2, the first slider 41 has a first protrusion 411, and the second slider 42 has a second protrusion 421, and the first protrusion 411 of the first slider 41 and the second protrusion 421 of the second slider 42 can be inserted into the slide groove 122 slidably along the second direction D2 from two openings of the slide groove 122 in the first direction D1, so as to further restrict the first slider 41 and the second slider 42 to slide only in the second direction D2. In addition, in this embodiment, both ends of the first slider 41 and the second slider 42 in the second direction D2 are arc-shaped, and the first groove 221, the second groove 231, the third groove 321 and the fourth groove 331 are arc-shaped concave shapes corresponding to the two ends of the first slider 41 and the second slider 42.

[0073] The first idle tooth 5 and the second idle tooth 6 are rotatably disposed in the third accommodating space 17 of the base 1 through a first rotating shaft 7 and a second rotating shaft 8 inserted in the third seat body 13 and the fourth seat body 14, respectively, and the first idle tooth 5 and the second idle tooth 6 are located between the first gear member 24 and the second gear member 34. The first idle tooth 5 has a first idle tooth portion 51 corresponding to the first gear portion 241, a first recessed portion 52 corresponding to the first protruding portion 242, and a first starting idle tooth portion 53 having a larger module than the first idle tooth portion 51 and corresponding to the first starting gear portion 243. The second idle tooth 6 has a second idle tooth portion 61 corresponding to the second gear portion 341, a second recessed portion 62 corresponding to the second protruding portion 342, and a second starting idle tooth portion 63 having a larger module than the second idle tooth portion 61 and corresponding to the second starting gear portion 343. The first idle tooth portion 51 and the second idle tooth portion 61 mesh with each other and are used to mesh together between the first gear portion 241 of the first gear member 24 and the second gear portion 341 of the second gear member 34 so that the first gear portion 241 of the first gear member 24 and the second gear portion 341 of the second gear member 34 are linked to each other.

[0074] Wherein, the first rotating shaft 2 can rotate between a first initial angle position and a first terminal angle position relative to the base 1, and there is a first transition angle position between the first initial angle position and the first terminal angle position, and the second rotating shaft 3 can rotate between a second initial angle position and a second terminal angle position relative to the base 1, and there is a second transition angle position between the second initial angle position and the second terminal angle position. In this embodiment, the first transition angle position is in the middle between the first initial angle position and the first terminal angle position, and the second transition angle position is in the middle between the second initial angle position and the second terminal angle position, and the angle difference between the first initial angle position and the first terminal angle position is 180 degrees, and the angle difference between the second initial angle position and the second terminal angle position is 180 degrees. Therefore, the angle difference between the first transition angle position and the first initial angle position and the angle difference between the first transition angle position and the first terminal angle position are both 90 degrees, and the angle difference between the second transition angle position and the second initial angle position and the angle difference between the second transition angle position and the second terminal angle position are also both 90 degrees.

[0075] During the process in which the first rotating shaft 2 rotates from the first initial angle position along a first rotation direction R1 to the first terminal angle position, and the second rotating shaft 3 rotates from the second initial angle position along a second rotation direction R2 opposite to the first rotation direction R1 to the second terminal angle position, the dual-axis multi-stage switching hinge 100 enables the two bodies to rotate 180 degrees respectively, so that the two bodies rotate 360 ​​degrees in total, thereby converting the two bodies of the electronic device from one folded state to the folded state of the other side. In detail, when the user applies force to the two bodies, the first rotating shaft 2 and the second rotating shaft 3 can be rotated relative to the base 1, so that the two bodies can pivot between the folded states of the different sides. It should be noted that, in other embodiments, the first transition angle position is not necessarily in the middle between the first initial angle position and the first terminal angle position, and the second transition angle position is not necessarily in the middle between the second initial angle position and the second terminal angle position, and the angle difference between the first initial angle position and the first terminal angle position and the angle difference between the second initial angle position and the second terminal angle position may not be 180 degrees but other angles, which are not limited to this embodiment. In addition, the actuation modes of the two bodies described above are only examples, that is, the two bodies do not necessarily have to switch between the two folded states, which should not be limited to this embodiment.

[0076] See also Figures 6 to 10When the first rotating shaft 2 is at the first initial angle position and the second rotating shaft 3 is at the second initial angle position, the first groove 221 faces the first slider 41 and the third shallow groove portion 321b of the third groove 321 faces the first slider 41, so the first slider 41 cannot slide and is partially accommodated in the first groove 221 and the third shallow groove portion 321b of the third groove 321; the second groove 231 faces away from the second slider 42 and the fourth deep groove portion 331b of the fourth groove 331 faces the second slider 42, so the second slider 42 cannot slide and is partially accommodated in the fourth deep groove portion 331b of the fourth groove 331. In addition, the inner wall surface of the fourth deep groove portion 331b of the fourth groove 331 of the second rotating shaft 3 is blocked by the second slider 42 in the second rotation direction R2 to prevent the second rotating shaft 3 from rotating in the second rotation direction R2. In addition, the first gear portion 241 faces away from the first idle tooth portion 51, and the second gear portion 341 faces away from the second idle tooth portion 61. Therefore, the first gear portion 241 and the second gear portion 341 are not linked to each other through the first idle tooth portion 51 and the second idle tooth portion 61. Furthermore, in this state, the first protrusion 242 is located in the first recess 52 to limit the rotation of the first idle tooth 5, and the second protrusion 342 is located in the second recess 62 to limit the rotation of the second idle tooth 6, while the first starting gear portion 243 does not mesh with the first starting idle tooth portion 53, and the second starting gear portion 343 does not mesh with the second starting idle tooth portion 63.

[0077] It should be noted that, in this embodiment, the inner wall surface of the first groove 221 of the first rotating shaft 2 is stopped by the first slider 41 in the second rotation direction R2, thereby preventing the first rotating shaft 2 from rotating in the second rotation direction R2; and the inner wall surface of the fourth deep groove portion 331b of the fourth groove 331 of the second rotating shaft 3 is stopped by the second slider 42 in the first rotation direction R1, thereby preventing the second rotating shaft 3 from rotating in the first rotation direction R1. However, in other embodiments, other blocks may be provided to prevent the first rotating shaft 2 from rotating in the second rotation direction R2 and to prevent the second rotating shaft 3 from rotating in the first rotation direction R1, which is not limited to this embodiment.

[0078] See also Figures 11 to 13When the first rotating shaft 2 is at other positions between the first initial angle position and the first transition angle position, and the second rotating shaft 3 is at the second initial angle position, the first groove 221 faces the first slider 41 and the third shallow groove portion 321b of the third groove 321 faces the first slider 41, so the first slider 41 cannot slide and is partially accommodated in the first groove 221 and the third shallow groove portion 321b of the third groove 321; the second groove 231 faces away from the second slider 42 and the fourth deep groove portion 331b of the fourth groove 331 faces the second slider 42, so the second slider 42 cannot slide and is partially accommodated in the fourth deep groove portion 331b of the fourth groove 331. In addition, the inner wall surface of the fourth deep groove portion 331b of the fourth groove 331 of the second rotating shaft 3 is blocked by the second slider 42 in the second rotation direction R2 to prevent the second rotating shaft 3 from rotating in the second rotation direction R2. In addition, the first gear portion 241 faces away from the first idle gear portion 51 , and the second gear portion 341 faces away from the second idle gear portion 61 . Therefore, the first gear portion 241 and the second gear portion 341 are not linked via the first idle gear portion 51 and the second idle gear portion 61 .

[0079] See also Figures 14 to 18When the first rotating shaft 2 is at the first transition angle position and the second rotating shaft 3 is at the second initial angle position, the first groove 221 faces the first slider 41 and the third shallow groove portion 321b of the third groove 321 faces the first slider 41. Therefore, the first slider 41 cannot slide and is partially accommodated in the first groove 221 and the third shallow groove portion 321b of the third groove 321; the second groove 231 faces the second slider 42 and the fourth deep groove portion 331b of the fourth groove 331 faces the second slider 42. Therefore, the second slider 42 can slide and is partially accommodated in the second groove 231 and / or the fourth deep groove portion 331b of the fourth groove 331. In this embodiment, the second slider 42 can slide and is still partially accommodated in the fourth deep groove portion 331b of the fourth groove 331. However, it should be noted that if the second rotating shaft 3 rotates in the second rotation direction R2 at this time, the second rotating shaft 3 will force the second slider 42 to slide toward the second groove 231. Furthermore, the inner wall surface of the first groove 221 of the first rotating shaft 2 is blocked by the first slider 41 in the first rotation direction R1 to prevent the first rotating shaft 2 from rotating in the first rotation direction R1. In addition, the first gear portion 241 is meshed with the first idle tooth portion 51, but the second gear portion 341 faces away from the second idle tooth portion 61, so the first gear portion 241 and the second gear portion 341 are not linked to each other through the first idle tooth portion 51 and the second idle tooth portion 61; furthermore, in this state, the first convex portion 242 is about to be disengaged from the first concave portion 52 to allow the first idle tooth 5 to rotate, the second convex portion 342 is located in the second concave portion 62 to limit the rotation of the second idle tooth 6, and the first starting gear portion 243 is meshed with the first starting idle tooth portion 53, and the second starting gear portion 343 is not meshed with the second starting idle tooth portion 63.

Furthermore, the inner wall surface of the first groove 221 of the first rotating shaft 2 is blocked by the first slider 41 in the first rotating direction R1 to prevent the first rotating shaft 2 from rotating in the first rotating direction R1; the inner wall surface of the second groove 231 of the first rotating shaft 2 is blocked by the second slider 42 in the second rotating direction R2 to prevent the first rotating shaft 2 from rotating in the second rotating direction R2. In addition, the first gear portion 241 is meshed with the first idle tooth portion 51, but the second gear portion 341 faces away from the second idle tooth portion 61, so the first gear portion 241 and the second gear portion 341 are not linked to each other through the first idle tooth portion 51 and the second idle tooth portion 61.

[0081] See also Figure 22 to Figure 26When the first rotating shaft 2 is at the first transition angle position and the second rotating shaft 3 is at the second transition angle position, the first groove 221 faces the first slider 41 and the third deep groove portion 321a of the third groove 321 faces the first slider 41. Therefore, the first slider 41 can slide and be partially accommodated in the first groove 221 and / or the third deep groove portion 321a of the third groove 321. In this embodiment, the first slider 41 is still accommodated in the first groove 221, but it should be noted that at this time, if the first rotating shaft 2 rotates in the first rotation direction R1, the first rotating shaft 2 forces the first slider 41 to slide toward the third deep groove portion 321a of the third groove 321; the second groove 231 faces the second slider 42 and the fourth shallow groove portion 331a of the fourth groove 331 faces the second slider 42. Therefore, the second slider 42 cannot slide and is partially accommodated in the second groove 231 and the fourth shallow groove portion 331a of the fourth groove 331. Furthermore, the inner wall surface of the second groove 231 of the first rotating shaft 2 is stopped by the second slider 42 in the second rotation direction R2 to prevent the first rotating shaft 2 from rotating in the second rotation direction R2. In addition, the first gear portion 241 is meshed with the first idle tooth portion 51, and the second gear portion 341 is meshed with the second idle tooth portion 61, so the first gear portion 241 and the second gear portion 341 are linked to each other through the first idle tooth portion 51 and the second idle tooth portion 61; furthermore, in this state, the first convex portion 242 is about to be disengaged from the first concave portion 52 to allow the first idle tooth 5 to rotate, the second convex portion 342 is about to be disengaged from the second concave portion 62 to allow the second idle tooth 6 to rotate, and the first starting gear portion 243 is meshed with the first starting idle tooth portion 53, and the second starting gear portion 343 is meshed with the second starting idle tooth portion 63.

In addition, the first gear portion 241 is meshed with the first idle tooth portion 51, and the second gear portion 341 is meshed with the second idle tooth portion 61, so the first gear portion 241 and the second gear portion 341 are linked to each other through the first idle tooth portion 51 and the second idle tooth portion 61.

[0083] See also Figure 30 to Figure 34 When the first rotating shaft 2 is at the first terminal angle position and the second rotating shaft 3 is at the second terminal angle position, the first groove 221 faces away from the first slider 41 and the third deep groove portion 321a of the third groove 321 faces the first slider 41, so the first slider 41 cannot slide and is partially accommodated in the third deep groove portion 321a of the third groove 321; the second groove 231 faces the second slider 42 and the fourth shallow groove portion 331a of the fourth groove 331 faces the second slider 42, so the second slider 42 cannot slide and is partially accommodated in the second groove 231 and the fourth shallow groove portion 331a of the fourth groove 331. In addition, the first gear portion 241 is meshed with the first idle tooth portion 51, and the second gear portion 341 is meshed with the second idle tooth portion 61, so the first gear portion 241 and the second gear portion 341 are linked to each other through the first idle tooth portion 51 and the second idle tooth portion 61; furthermore, in this state, the first protrusion 242 is outside the first recess 52, so the first idle tooth 5 can rotate, and the second protrusion 342 is outside the second recess 62, so the second idle tooth 6 can rotate, while the first starting gear portion 243 and the first starting idle tooth portion 53 do not mesh with each other, and the second starting gear portion 343 and the second starting idle tooth portion 63 do not mesh with each other.

[0084] It should be noted that, in this embodiment, the inner wall surface of the second groove 231 of the first rotating shaft 2 is stopped by the second slider 42 in the first rotation direction R1, thereby preventing the first rotating shaft 2 from rotating in the first rotation direction R1; and the inner wall surface of the third deep groove portion 321a of the third groove 321 of the second rotating shaft 3 is stopped by the first slider 41 in the second rotation direction R2, thereby preventing the second rotating shaft 3 from rotating in the second rotation direction R2. However, in other embodiments, other blocks may be provided to prevent the first rotating shaft 2 from rotating in the first rotation direction R1 and the second rotating shaft 3 from rotating in the second rotation direction R2, which is not limited to this embodiment.

[0085] In addition, to summarize the actuation between the structures on the first gear member 24, the second gear member 34, the first idle tooth 5 and the second idle tooth 6, when the first rotating shaft 2 is between the first transition angle position and the first terminal angle position, and the second rotating shaft 3 is between the second transition angle position and the second terminal angle position, the first idle tooth portion 51 and the second idle tooth portion 61 are engaged between the first gear portion 241 of the first gear member 24 and the second gear portion 341 of the second gear member 34, thereby making the first rotating shaft 2 and the second rotating shaft 3 move synchronously. When the first rotating shaft 2 is between the first initial angle position and the first transition angle position and has not yet reached the first transition angle position, the first protrusion 242 is located in the first recess 52 to limit the rotation of the first idle tooth 5. When the first rotating shaft 2 rotates to the first transition angle position, the first protrusion 242 gradually escapes from the first recess 52 to allow the first idle tooth 5 to rotate. When the second rotating shaft 3 is between the second initial angle position and the second transition angle position and has not yet reached the second transition angle position, the second protrusion 342 is located in the second recess 62 to limit the rotation of the second idle tooth 6. When the second rotating shaft 3 rotates to the second transition angle position, the second protrusion 342 gradually escapes from the second recess 62 to allow the second idle tooth 6 to rotate. In this way, the first idle tooth 5 and the second idle tooth 6 can be prevented from idling when the first gear portion 241 of the first rotating shaft 2 and the second gear portion 341 of the second rotating shaft 3 are not linked. In addition, when the first rotating shaft 2 is at the first transition angle position, the first starting gear portion 243 and the first starting idle tooth portion 53 are meshed with each other; when the second rotating shaft 3 is at the second transition angle position, the second starting gear portion 343 and the second starting idle tooth portion 63 are meshed with each other, thereby ensuring the linkage and meshing strength between the first rotating shaft 2 and the first idle tooth 5 and between the second rotating shaft 3 and the second idle tooth 6 at the moment when the first rotating shaft 2 and the second rotating shaft 3 begin to link through the first idle tooth 5 and the second idle tooth 6.

[0086] However, in a variant embodiment, the first idle tooth 5 and the second idle tooth 6 can be omitted, and the first protrusion 242 of the first gear member 24 and the second protrusion 342 of the second gear member 34 can be omitted. In addition, the first gear portion 241 of the first gear member 24 and the second gear portion 341 of the second gear member 34 can be directly meshed with each other and linked, and the first starting gear portion 243 of the first gear member 24 and the second starting gear portion 343 of the second gear member 34 can also be directly meshed with each other and linked.

[0087] In summary, the present invention achieves multi-stage switching of more than three stages by rotating the first rotating shaft 2 and the second rotating shaft 3 in turn and then rotating synchronously, through the cooperation between the first rotating shaft 2, the second rotating shaft 3, and the first slider 41 and the second slider 42 of the slider group 4, and the cooperation between the first gear portion 241 of the first rotating shaft 2 and the second gear portion 341 of the second rotating shaft 3.

[0088] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
