In a unit rotation stroke, the elastic member 293 can undergo at least one compression and one expansion. Therefore, when the first synchronization arm 26 and the second synchronization arm 27 are rotated, the first synchronization arm 26 and the second synchronization arm 27 exert a force to overcome the force of the elastic member 293. When the first synchronization arm 26 and the second synchronization arm 27 do not rotate, only the force of the electronic device 100 itself cannot overcome the elastic member 293. force, thereby maintaining the stability of the electronic device 100 .

Then, during the unfolding or folding process of the electronic device 100, due to the function of the elastic member 293, the electronic device 100 can be rapidly unfolded or folded.

In one embodiment, when the electronic device 100 is unfolded from the fully folded state to the fully unfolded state, it undergoes a plurality of unit rotation strokes. Then, during the unfolding or folding process of the electronic device 100 , the electronic device 100 may be in a state between the fully folded state and the fully unfolded state only by relying on the action of the elastic member 293 . When the density of the first limiting protrusions 2643 and the second limiting protrusions 2943 is sufficiently large, the electronic device 100 can be in any state between the fully folded state and the fully expanded state only by relying on the action of the elastic member 293 .

In one embodiment, the support plate 50 may be a part of the hinge module 20 . In one embodiment, the support plate 50 can be replaced by the first fixing base 25 and the second fixing base 221 .

Please refer to FIG. 23 . FIG. 23 discloses a simplified structural schematic diagram of a part of the rotating shaft module 20 in the embodiment shown in FIG. 1 of the present application. The synchronizing arms such as the first synchronizing arm 26 and the second synchronizing arm 27 respectively have two different and parallel first rotating axes A1 and A2, and the rotating arms 224 such as the first rotating arm 225 and the second rotating arm 226 are respectively There are two non-axial and parallel second rotation axes B1, B2, and the connecting arm 227 such as the first connecting arm 228 and the second connecting arm 229 respectively have two non-axial and parallel third rotation axes C1, C2.

The planes where the first rotation axes A1 and A2 are located are parallel to the planes where the second rotation axes B1 and B2 are located and the planes where the third rotation axes C1 and C2 are located.

In addition, the first rotation axes A1, A2 are located between the second rotation axes B1, B2 and the third rotation axes C1, C2.

The synchronizing arm and the rotating arm 224 are designed with a triangular stability design. When the electronic device 100 is completely flattened, a damping force can be given to the electronic device 100 to keep the electronic device 100 flat, so as to prevent the electronic device 100 from unfolding at an excessively large angle.

In addition, there is a relative sliding amount between the synchronizing arm and the connecting seat, which can reduce the sliding amount between the rotating arm 224 and the connecting seat, so that the supporting plate can be rotated quickly, and the overall structural size of the electronic device 100 can be reduced by 20%. Provides more space.

The connecting arm 227 and the rotating arm 224 are designed with triangular stability, so that when the electronic device 100 is completely flattened, a damping force is given to the electronic device 100 to keep it flat, so as to prevent the electronic device 100 from being too large.

The projections of the third rotation axes C1 and C2 on the plane where the second rotation axes B1 and B2 are located are located between the second rotation axes B1 and B2. When the electronic device 100 is folded, the connecting arm 227 and the rotating arm 224 adopt the design of triangular stability. In addition, when the electronic device 100 is unfolded, the intersection point of the synchronization arm and the rotating arm 224 is farther from the second rotating axes B1 and B2 than when the electronic device 100 is folded. When in the fully folded state and unfolding, the resistance of the synchronizing arm to unfolding increases gradually, which improves the service life of the electronic device 100 .

When the electronic device 100 is folded, the first connecting seat 23 and the second connecting seat 24 are stressed, so that when the electronic device 100 is folded toward the display module 200 side, the first rotating arm 225 and the first connecting seat 23 Sliding connection, the second rotating arm 226 and the second connecting base 24 are slidably connected, so that the first rotating arm 225 and the second rotating arm 226 are folded toward the display module 200 side. The third rotation axis on which the arm 229 rotates is different from the second rotation axis on which the first synchronization arm 26 and the second synchronization arm 27 rotate. 23 is limited by the radius of the first connecting arm 228, and the first rotating arm 225 slides with the first connecting seat 23 in order to compensate for the difference in the rotation axis. During the sliding process, the first supporting plate 30 will be pulled, The first support plate 30 and the first connection seat 23 are rotated, so that the first support plate 30 drives the display module 200 to move to the side away from the display module 200 on the side away from the first connection seat 23 . At the same time, when the second connecting seat 24 rotates together with the second rotating arm 226, it is restricted by the second connecting seat 24 from rotating with the radius of the second connecting arm 229, and the second rotating arm 226 in order to compensate for the difference in the rotation axis, When sliding with the second connecting seat 24, during the sliding process, the second supporting plate 40 will be pulled, so that the second supporting plate 40 and the second connecting seat 24 will rotate, thereby making the second supporting plate 40 away from the first connecting seat. One side of 23 drives the display module 200 to move to the side away from the display module 200 . Under the movement of the first supporting plate 30 and the second supporting plate 40 , the display module 200 forms a water drop-shaped folded shape at the folded position, so as to prevent the display module 200 from being folded to form marks. In addition, the space between the part of the first casing 400 and the part of the second casing 600 for the folded display module 200 can be made extremely small, and even the folded electronic device 100 can be made thinner.

During the folding process, the first synchronizing arm 26 is subjected to the force given by the first rotating arm 225, so that the first synchronizing arm 26 rotates, and at the same time the second synchronizing arm 27 also rotates, thereby causing the first rotating arm 225 and the second rotating arm 226 synchronous rotation. At this time, since the first rotation axis of the synchronization arm is different from the second rotation axis of the rotation arm 224, the synchronization arm and the rotation arm 224 will slide relative to each other, and the synchronization arm will rotate to a certain extent.

During the unfolding action, the first connecting seat 23 and the second connecting seat 24 are stressed, so that the electronic device 100 is unfolded to the side away from the display module 200 .

It can be understood that when the electronic device 100 performs the folding action or the stretching action, the first rotating arm 225 and the first connecting seat 23 are relatively stationary and rotate around the second rotating axis, and the first connecting seat 23 and the first connecting arm 228 only slides with the first connecting seat 23 under the limitation of the distance between the third rotating shaft of the 228, the second rotating arm 226 is relatively stationary with the second connecting seat 24 and rotates with the second rotating shaft, and is connected between the second connecting seat 24 and the second connecting seat 24. The second connecting arm 229 only slides with the second connecting seat 24 under the limitation of the distance between the second rotating shafts of the second connecting arm 229 .
