The second switching seat 150' is rotatably positioned between the third hinge module 130' and the fourth hinge module 140 '.

Referring to fig. 1B and fig. 1D, when the second body 120 is unfolded to a first angle A1 relative to the first body 110, wherein the range of the first angle A1 is between 1 degree and 90 degrees (90 degrees shown in fig. 1B), the second body 120 drives the second switching base 150 'to rotate relative to the third rotating shaft 131' and the fourth rotating shaft 141', so that no torsion is generated in the unfolding process of the second switching base 150'.

Referring to fig. 1C and fig. 1D, when the second body 120 is unfolded to a second angle A2 greater than the first angle A1 relative to the first body 110, wherein the second angle A2 ranges from 91 degrees to 180 degrees (135 degrees shown in fig. 4A), the second body 120 applies a force to the second switching seat 150', so that the second switching seat 150' pushes the fourth rotating shaft 141' to rotate along the axial direction AD, and thus the fourth rotating shaft 141' generates a torsion force during the unfolding process of the second switching seat 150'.

Referring to fig. 1C and fig. 1D, when the second body 120 is folded to the second angle A2 relative to the first body 110, i.e. an angle range from 180 degrees to 90 degrees, the second switch base 150 'rotates relative to the third rotating shaft 131' and the fourth rotating shaft 141', so that no torsion is generated in the folding process of the second switch base 150'.

Referring to fig. 1B and fig. 1D, when the second body 120 is folded to the first angle A1 relative to the first body 110, i.e. the angle range from 90 degrees to 0 degrees, the second switching seat 150 'pushes the third rotating shaft 131' to rotate along the axial direction AD, so that the third rotating shaft 131 'generates a torsion force during the folding process of the second switching seat 150'.

Further, the detailed structure and rotation process of the third hinge module 130', the fourth hinge module 140' and the second switch seat 150' are as described in paragraphs 0015 to 0031, and will not be described in detail below.

Referring to fig. 1A, 1D, 2A and 2B, when the second body 120 is overlapped on the first body 110 in parallel, the second one-way bearing 142 and the fourth one-way bearing 142 'are stopped by the second bracket 143 and the fourth bracket 143' (see fig. 5A and 5C), respectively, and stay at the initial positions, a 90-degree gap exists between the second one-way bearing 142 and the first switch seat 150, and a 90-degree gap exists between the fourth one-way bearing 142 'and the second switch seat 150'.

Referring to fig. 2A and fig. 2B, one of the protrusions 151 of the first switch seat 150 drives the first outer ring 1322 away from the first stop block 1331. The other protrusion 151 of the first switch seat 150 does not contact the second outer ring 1422, and the second stop 1431 abuts against the second outer ring 1422 to limit the second outer ring 1422 to a 90-degree position (with respect to the axial direction AD).

Referring to fig. 1D, fig. 3A and fig. 3B, when the second body 120 is unfolded by 1 to 90 degrees relative to the first body 110, the first switch base 150 rotates relative to the first rotating shaft 131 and the second rotating shaft 141, the first torsion spring 134 pushes the first outer ring 1322 to rotate relative to the first inner ring 1321 so as to be attached to the corresponding bump 151 of the first switch base 150, the second switch base 150 'rotates relative to the third rotating shaft 131' and the fourth rotating shaft 141', and the third torsion spring 134' pushes the third outer ring 1322 'to rotate relative to the fourth inner ring 1321' so as to be attached to the corresponding bump 151 'of the second switch base 150', at this time, neither the first switch base 150 nor the second switch base 150 'drives the first rotating shaft 131 and the third rotating shaft 131' to pivot, so that the second body 120 has no torsion force at the stage of unfolding by 1 to 90 degrees, which is beneficial for a user to unfold the second body 120 with a single hand.

Referring to fig. 1D, fig. 4A and fig. 4B, when the second body 120 is unfolded by more than 90 degrees relative to the first body 110, the protrusion 151 of the first switch base 150 drives the second one-way bearing 142, the second rotating shaft 141 and the second torsion member 145 to pivot along the axial direction AD, so that the second torsion member 145 rubs the second bracket 143 to generate torsion (refer to fig. 5A and fig. 5B).

Referring to fig. 5A and 5C, the protrusion 151' of the second switch seat 150' drives the fourth one-way bearing 142', the fourth rotating shaft 141' and the fourth torsion member 145' to pivot along the axial direction AD, so that the fourth torsion member 145' rubs the fourth bracket 143' to generate torsion, and therefore the second body 120 is 100% torsion at a stage of being unfolded by more than 90 degrees, thereby preventing the second body 120 from being tilted due to insufficient torsion or external force.

Referring to fig. 4A and 4B, at this time, the second body 120 is unfolded 135 degrees relative to the first body 110, the first one-way bearing 132 is stopped by the first stop block 1331 of the first bracket 133 and stays at the 90-degree position, and the third one-way bearing 132' is stopped by the third stop block 1331' of the third bracket 133' and stays at the 90-degree position. At this time, a 45 degree gap exists between the projection 151 of the first switching seat 150 and the first one-way bearing 132, and a 45 degree gap exists between the projection 151' of the second switching seat 150' and the third one-way bearing 132 '.

Referring to fig. 5A to 5C, in other embodiments, the second stopping block 1431 'is removed, so that the protrusion 151' of the second switching seat 150 'and the third one-way bearing 132' are in contact with each other when the second body 120 is unfolded 135 degrees relative to the first body 110, and when the second body 120 is folded to 90 degrees relative to the first body 110, the second switching seat 150 'drives the third rotating shaft 131' and the third torsion member 135 'to pivot to contact the third bracket 133', so that the stage of folding the second body 120 from 135 degrees to 90 degrees is 50% torsion.

In other embodiments, the first stopping block 1331 and the second stopping block 1431' are removed, so that the protrusion 151 of the first switching seat 150 and the protrusion 151' of the second switching seat 150' respectively contact the first one-way bearing 132 and the third one-way bearing 132' in a state that the second body 120 is unfolded 135 degrees relative to the first body 110, when the second body 120 is folded to 90 degrees relative to the first body 110, the first switching seat 150 will drive the first rotating shaft 131 and the first torsion member 135 to pivot to contact the first bracket 133, and the second switching seat 150' will drive the third rotating shaft 131 and the third torsion member 135' to pivot to contact the third bracket 133', so that the second body 120 is 100% torsion at a stage of being folded from 135 degrees to 90 degrees.

Referring to fig. 1D, fig. 3A-3B, and fig. 2A-2B, when the second body 120 is folded by less than 90 degrees relative to the first body 110, the protrusion 151 of the first switch base 150 drives the first one-way bearing 132, the first rotating shaft 131, and the first torsion member 135 to pivot along the axial direction AD, so that the first torsion member 135 rubs the first bracket 133 to generate a torsion force (refer to fig. 5A and 5B). Referring to fig. 5A and 5B, the protrusion 151' of the second switching seat 150' drives the third one-way bearing 132', the third rotating shaft 131' and the third torsion member 135' to pivot along the axial direction AD, so that the third torsion member 135' rubs the third bracket 133' to generate a torsion, and therefore the torsion is 100% when the second body 120 is folded by less than 90 degrees relative to the first body 110, thereby preventing the second body 120 from falling to the first body 110 due to insufficient torsion or external force.

Referring to fig. 7, in the embodiment, the electronic device 100 employs a first hinge module 130a and a second hinge module 140a, and the difference is that a first torsion element 135a of the first hinge module 130a is sleeved on a first rotating shaft 131a to provide torsion, and a first bracket 133a and the first torsion element 135a are an integrated structure. The second torsion member 145a of the second hinge module 140a is sleeved on the second rotating shaft 141a to provide torsion, and the second bracket 143a and the second torsion member 145a are an integral structure.

Referring to fig. 8, in the present embodiment, the electronic device 100 employs a first hinge module 130b and a second hinge module 140b, and the difference is that a first bracket 133b of the first hinge module 130b is axially formed on the first rotating shaft 131b, that is, the first bracket 133b and the first rotating shaft 131b are integrally formed. The second bracket 143b of the second hinge module 140b is axially formed on the second rotating shaft, that is, the second bracket 143b and the second rotating shaft are an integral structure.

In summary, the second body of the electronic device is fixedly connected to the first switching seat, and when the second body is unfolded from the folded state to a first angle relative to the first body, the first switching seat rotates relative to the first rotating shaft and the second rotating shaft, and at this time, the first switching seat does not generate torsion, so that a user can unfold the second body from the first body with a single hand. When the second body is continuously unfolded to a second angle larger than the first angle relative to the first body, the first switching seat pushes the second hinge module and the second rotating shaft to rotate to form torsion, so that the second body is positioned at the second angle and cannot fall backwards due to gravity attraction.
