Wherein, the folding device 10 is switchable between an unfolded state and a folded state, as shown in fig. 5 and fig. 6, a plane where the rotation axis of the first link 2 and the support 1 and the rotation axis of the second link 3 and the support 1 are located is a reference plane, in the unfolded state, the rotation axis of the first rotating arm 4 and the support 1 and the rotation axis of the second rotating arm 5 and the support 1 are located at the same side of the reference plane, the first link 2 and the first rotating arm 4 have an interference amount such that the first link 2 gives the force of the first rotating arm 4 toward the rotation center of the first link 2 and the support 1, and the second link 3 and the second rotating arm 5 have an interference amount such that the second link 3 gives the force of the second rotating arm 5 toward the rotation center of the second link 3 and the support 1.

As shown in fig. 8 and 9, in the process of switching from the unfolded state to the folded state, the first turning arm 4 and the second turning arm 5 are turned toward the side of the reference surface close to the turning axis of the first turning arm 4 and the second turning arm 5 and the stand 1; when the folding device 10 is switched from the folded state to the unfolded state until the folding device 10 is in the unfolded state, the direction of the moment acting on the first and second turning arms 4 and 5 is opposite to the direction in which the folding device 10 is turned toward the folded state, thereby supporting the folding device 10 in the unfolded state, supporting the apparatus provided with the folding device 10 in the unfolded state, and avoiding the folding device 10 from being switched from the unfolded state toward the folded state.
According to the folding device 10 of the embodiment of the present application, in the unfolded state, the use of the electronic apparatus 100 using the folding device 10 is facilitated by making the rotation axis of the first rotating arm 4 and the stand 1 and the rotation axis of the second rotating arm 5 and the stand 1 be located on the same side of the reference plane, and making the joint of the first link 2 and the first rotating arm 4 have an interference amount so that the first link 2 gives the first rotating arm 4 a force F in the direction of the rotation axis of the first link 2 and the stand 1, and the joint of the second link 3 and the second rotating arm 5 has an interference amount so that the second link 3 gives the second rotating arm 5 a force F in the direction of the rotation axis of the second link 3 and the stand 1, so that the first rotating arm 4 and the second rotating arm 5 have a support moment opposite to the folding direction, thereby supporting the folding device 10 in the unfolded state, avoiding the folding device 10 from being switched from the unfolded state to the folded state, and further making the apparatus connected to the folding device 10 in the unfolded state.
As shown in fig. 5, 7, 10, and 11, the holder 1 has a first contact portion 13 and a second contact portion 14, the first rotating arm 4 has a first engaging portion 41, the second rotating arm 5 has a second engaging portion 51, one of the first rotating arm 4 and the holder 1 is provided with a first rotating shaft 15, the other is provided with a first rotating hole 42 engaged with the first rotating shaft 15, one of the second rotating arm 5 and the holder 1 is provided with a second rotating shaft 16, the other is provided with a second rotating hole 52 engaged with the second rotating shaft 16, and clearance gaps are provided between an outer peripheral wall of the first rotating shaft 15 and an inner peripheral wall of the first rotating hole 42 and between an outer peripheral wall of the second rotating shaft 16 and an inner peripheral wall of the second rotating hole 52. As shown in fig. 5 and 7, in the unfolded state, the first abutting portion 13 abuts against the first engaging portion 41 and the second abutting portion 14 abuts against the second engaging portion 51 to prevent the first rotating arm 4 and the second rotating arm 5 from moving toward the direction approaching the stand 1, whereby it can be ensured that the first link 2 and the first rotating arm 4 have an interference amount so that a force F can act on the first rotating arm 4, and the second link 3 and the second rotating arm 5 have an interference amount so that a force F can act on the second rotating arm 5, so that the folding device 10 has a support moment opposite to the folding direction at the unfolding device, thereby supporting the folding device 10 in the unfolded state, facilitating the use of the electronic apparatus 100 employing the folding device 10.
Because there is interference between the first link 2 and the first swivel arm 4, the first swivel arm 4 applies a force on the first link 2 in a direction away from the bracket 1, there is interference between the second link 3 and the second swivel arm 5, the second swivel arm 5 applies a force on the second link 3 in a direction away from the bracket 1, the first link 2 and the second link 3 are stretched, so that a large yield stress is generated on the first link 2 and the second link 3, and the first link 2 and the second link 3 are easily subjected to yield deformation while providing a support moment. In the process of switching the folding device 10 from the unfolded state to the folded state, the interference amount between the first link 2 and the first rotating arm 4 is gradually increased, and the interference amount between the second link 3 and the second rotating arm 5 is gradually increased, so that the first link 2 and the second link 3 may yield or even break.
In the present application, as shown in fig. 10 and 11, the first abutting portion 13 is spaced from the first engaging portion 41, the second abutting portion 14 is spaced from the second engaging portion 51, and engages an avoidance gap between the first rotating shaft 15 and the first rotating hole 42 and an avoidance gap between the second rotating shaft 16 and the second rotating hole 52 in the process of the folded state and the unfolded state to the folded state, the first rotating arm 4 is moved toward the bracket 1 by the pull of the first link 2, and the second rotating arm 5 is moved toward the bracket 1 by the pull of the second link 3, so that the amount of interference between the first link 2 and the first rotating arm 4 is reduced and the amount of interference between the second link 3 and the second rotating arm 5 is reduced, thereby releasing most of the stress of the first link 2 and the second link 3 during the rotation, and preventing the first link 2 and the second link 3 from yielding and breaking during the rotation.
In conclusion, the folding device 10 of the present application not only provides a support moment through interference in the unfolded state, but also eliminates the yield stress gradually increased in the rotation process, ensures that the first connecting rod 2 and the second connecting rod 3 do not yield and break in the rotation process, and ensures the practicability and reliability of the design. The folding device 10 of the present application is small in size and occupies a small space of the electronic device 100.
Alternatively, as shown in fig. 7 and 11, in the developed state, the outer contour of the first abutting portion 13 is formed in an arc shape that is convex toward the first fitting portion 41, and the outer contour of the second abutting portion 14 is formed in an arc shape that is convex toward the second fitting portion 51. This facilitates the first abutting portion 13 and the first fitting portion 41 abutting in the unfolded state, the second abutting portion 14 and the second fitting portion 51 abutting, and the first abutting portion 13 and the first fitting portion 41 being spaced apart and the second abutting portion 14 and the second fitting portion 51 being spaced apart in the folded state.
