[0022] Example 1

[0023] As attached Figures 1 to 4An axial displacement pivot shown includes a torsion frame 1. A second torsion frame 2 is provided on one side of the torsion frame 1. A fixed driven shaft 3 is disposed through one side of the torsion frame 1. A sliding driven shaft 4 is disposed through one side of the second torsion frame 2. Link rods 5 are sleeved on the opposite sides of the fixed driven shaft 3 and the sliding driven shaft 4. The two groups of link rods 5 are connected by a rotating shaft 6. One side of the torsion frame 1 is connected to a sliding frame 7. The side of the sliding frame 7 away from the torsion frame 1 passes through the outer wall of the second torsion frame 2. The sliding frame 7 is slidably connected to the second torsion frame 2. A first driven gear 8 is key-connected to the outer wall of the middle part of the torsion frame 1 where the fixed driven shaft 3 is located. A first linkage gear 9 is provided on one side of the first driven gear 8. The first driven gear 8 meshes with the first linkage gear 9. A fixed driving shaft 10 is disposed through the side of the torsion frame 1 away from the fixed driven shaft 3.

One side of the outer wall of the fixed driving shaft 10 is connected to a fixed support 12. A second fixed support 13 is provided on one side of the bottom of the fixed support 12.

[0024] Among them: The torsion frame 1 and the second torsion frame 2 play a role of fixed connection. The fixed driven shaft 3 can rotate within the torsion frame 1. The sliding driven shaft 4 can rotate within the second torsion frame 2. The fixed driven shaft 3 and the sliding driven shaft 4 rotate to drive the link rods 5 on both sides to rotate synchronously. The link rods 5 rotate to form an included angle or expand, so that the torsion frame 1 and the second torsion frame 2 approach or move away from each other by sliding through the sliding frame 7. By twisting the fixed support 12 to turn 90 degrees and driving the fixed driving shaft 10 to rotate, the driving shaft 10 rotates to drive the driving gear 11 to rotate. The driving gear 11 rotates to drive the linkage gear 9 to rotate synchronously. The first linkage gear 9 rotates to drive the first driven gear 8 to rotate synchronously, so that the first driven gear 8 and the driving gear 11 rotate synchronously in the same rotation direction. The first driven gear 8 rotates to drive the fixed driven shaft 3 to rotate, thereby driving the link rods 5 to rotate synchronously, so as to realize expansion or closing. The second fixed support 13 plays a role of lifting and fixing.

[0025] Embodiment 2

[0026] On the basis of Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working modes, such as Figures 1 to 5 shown, see the following description for details:

[0027] As a preferred embodiment, a second driven gear 14 is key-connected to the outer wall of the middle part of the sliding driven shaft 4. The second driven gear 14 is disposed in the middle of the second torsion frame 2. Further, the sliding driven shaft 4 rotates synchronously with the second driven gear 14.

[0028] As a preferred embodiment, a second driven gear 14 is provided with a second linkage gear 15 on one side, and the second driven gear 14 meshes with the second linkage gear 15; further, the rotation of the second driven gear 14 drives the second linkage gear 15 to rotate synchronously.

[0029] As a preferred embodiment, a sliding drive shaft 16 is disposed through the second torsion frame 2 on the side away from the sliding driven shaft 4, and a second drive gear 17 is key-connected to the outer wall of one side of the sliding drive shaft 16; further, the sliding drive shaft 16 can rotate within the second torsion frame 2, and the rotation of the sliding drive shaft 16 drives the second drive gear 17 to rotate synchronously.

[0030] As a preferred embodiment, the second drive gear 17 is located in the middle of the second torsion frame 2 and the second drive gear 17 meshes with the second linkage gear 15; further, the rotation of the second drive gear 17 drives the second linkage gear 15 to rotate synchronously, thereby driving the second driven gear 14 to rotate, and the rotation of the second driven gear 14 drives the sliding driven shaft 4 to rotate, and the rotation of the sliding driven shaft 4 drives the corresponding connecting rod 5 to rotate synchronously, thereby realizing expansion or closing.

[0031] As a preferred embodiment, a sliding support 18 is connected to the outer wall of one side of the sliding drive shaft 16, the sliding support 18 is matched with the fixed support 12, and mounting through holes 19 are arranged on the surfaces of both the sliding support 18 and the fixed support 12; further, the mounting through holes 19 facilitate the installation of the sliding support 18 and the fixed support 12. By turning the sliding support 18 and the fixed support 12 outwards by 90 degrees respectively, the sliding drive shaft 16 and the fixed drive shaft 10 rotate synchronously in opposite directions, thereby driving the connecting rods 5 on both sides to rotate to form an angle, so that the torsion frame 1 and the second torsion frame 2 slide close to each other through the sliding frame 7, thereby realizing the expansion of the sliding support 18 and the fixed support 12. Conversely, when the sliding support 18 and the fixed support 12 are closed, the connecting rods 5 on both sides rotate in opposite directions to form a flat angle, so that when the two bodies of the electronic device rotate relative to each other, the gap between the bodies is minimized, thereby keeping the distance between the two display panels minimized during the relative rotation of the bodies, maintaining the integrity and coherence of the picture, and reducing the number of parts.

[0032] The working process of the present utility model is as follows: First, the fixed driven shaft 3 is rotatable within the torsion frame 1, and the sliding driven shaft 4 is rotatable within the second torsion frame 2. The fixed driven shaft 3 and the sliding driven shaft 4 rotate and drive the two-side connecting rods 5 to rotate synchronously. The connecting rods 5 rotate to form an angle or expand, so that the torsion frame 1 and the second torsion frame 2 slide through the sliding frame 7 to approach or move away from each other. By twisting the fixed support frame 12 to flip 90 degrees and drive the fixed driving shaft 10 to rotate, the driving shaft 10 rotates to drive the driving gear 11 to rotate. The driving gear 11 rotates to drive the linkage gear 9 to rotate synchronously. The first linkage gear 9 rotates to drive the first driven gear 8 to rotate synchronously, so that the first driven gear 8 and the driving gear 11 perform synchronous rotation in the same rotation direction. The first driven gear 8 rotates to drive the fixed driven shaft 3 to rotate, thereby driving the connecting rods 5 to rotate synchronously, so as to achieve expansion or closing. The second fixed support frame 13 plays a role of lifting and fixing. By flipping the sliding support frame 18 and the fixed support frame 12 outward by 90 degrees respectively, the sliding driving shaft 16 and the fixed driving shaft 10 rotate synchronously in opposite directions, thereby driving the two-side connecting rods 5 to rotate to form an angle, so that the torsion frame 1 and the second torsion frame 2 slide through the sliding frame 7 to approach each other, thereby realizing the expansion of the sliding support frame 18 and the fixed support frame 12. Conversely, when the sliding support frame 18 and the fixed support frame 12 are closed, the two-side connecting rods 5 rotate in opposite directions to form a flat angle, so that when the two bodies of the electronic device rotate relative to each other, the gap between the bodies reaches the minimum. Thereby, the distance between the two display panels is kept minimum when the bodies rotate relative to each other, so that the picture can maintain integrity and coherence, and the number of parts is reduced. The above is the working principle of this kind of axial displacement pivot.
