When the foldable electronic device 100 is folded, the first housing component 5 and the second housing component 6 rotate in opposite directions, at this time, the first rotating shaft 21 and the second rotating shaft 22 also rotate in opposite directions, the first protrusion 213 slides in the first sliding slot 233, the second protrusion 223 slides in the second sliding slot 234, the sliding directions of the first protrusion 213 and the second protrusion 223 are opposite, the first protrusion 213 moves from the point E to the point E ', the second protrusion 223 moves from the point F to the point F', and the slider 23 slides to one end near the first fixing frame 24. When the foldable electronic device 100 is unfolded, the first housing component 5 and the second housing component 6 rotate back to back, at this time, the first rotating shaft 21 and the second rotating shaft 22 also rotate back to back, the first protrusion 213 slides in the first sliding slot 233, the second protrusion 223 slides in the second sliding slot 234, the sliding directions of the first protrusion 213 and the second protrusion 223 are opposite, the first protrusion 213 moves from the point E 'to the point E, the second protrusion 223 moves from the point F' to the point F, and the slider 23 slides towards one end close to the second fixing frame 25. During this rotation, the first rotating shaft 21 and the second rotating shaft 22 can rotate synchronously due to the restriction of the first sliding groove 233 and the second sliding groove 234. Specifically, when the first protrusion 213 moves in the first sliding groove 233, the slider 23 can only be driven to move toward the first fixing frame 24 because the slider 23 cannot rotate, and the moving distance of the slider 23 also limits the rotating distance of the second protrusion 223 because the second protrusion 223 is located in the second sliding groove 234, that is, the first protrusion 213 and the second protrusion 223 rotate synchronously, so that the first housing component 5 and the second housing component 6 connected to the first rotating shaft 21 and the second rotating shaft 22 can rotate synchronously, and further, the portion of the display screen connected to one side of the first housing component 5 and the portion connected to one side of the second housing component 6 can rotate synchronously.

The other end of the second connecting shaft 33 passes through the second limiting member 39 and then is clamped on the damping member 31.

The first limiting member 38 and the second limiting member 39 are substantially T-shaped, and the first connecting shaft 32 and the second connecting shaft 33 are respectively located at two sides of the first limiting member 38 and the second limiting member 39 opposite to each other.

The first arc-shaped receiving groove 361 of the first fixing element 36 and the second arc-shaped receiving groove 371 of the second fixing element 37 are respectively located at two sides of the mounting cavity 11 in a biased manner, that is, the center lines of the first arc-shaped receiving groove 361 and the second arc-shaped receiving groove 371 are respectively located at two sides of the center line of the mounting cavity 11.

In addition, the centers of circles of the arcs on the same side of the installation cavity 11 are located on the same straight line, that is, the centers of circles of the first installation groove 240 and the first engaging tooth 341, and the centers of circles of the second installation groove 250 and the second engaging tooth 351 are located on the same straight line, respectively.

In the process of turning over the first housing assembly 5 and the second housing assembly 6, the first housing assembly 5 drives the first connecting member 34 to rotate, so that the first connecting shaft 32 engaged with the first connecting member 34 receives an acting force for rotating the first connecting shaft, and at the moment, the damping member 31 generates a force opposite to the acting force to prevent the first connecting shaft 32 from rotating. Similarly, the second housing assembly 6 rotates the second connecting member 35, so that the second connecting shaft 33 engaged with the second connecting member 35 is subjected to a force for rotating the second connecting shaft, and at this time, the damping member 31 generates a force opposite to the force for preventing the second connecting shaft 33 from rotating. That is, the foldable mechanism is made to generate a damping feeling when folded. Meanwhile, the centers of the first arc-shaped receiving groove 361 and the second arc-shaped receiving groove 371 are at the position of the C point, so that the display screen can be bent and folded with a specific curvature and a specific track when the first connecting piece 34 and the second connecting piece 35 rotate in the corresponding arc-shaped receiving grooves.

In addition, the first connecting shaft 32 and the second connecting shaft 33 are respectively matched with the damping piece 31 to generate damping feeling, and the first rotating shaft 21 and the second rotating shaft 22 can only relatively rotate at the same angle due to the limitation of the first sliding groove 233 and the second sliding groove 234, so that the reliability of synchronization is ensured.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
