The following describes a specific operation process of the screen folding structure of the present embodiment:
during the process from folding to unfolding, the first support 2 and the second support 3 start to rotate and move away from each other, at this time, the first cam portion 17 of the first slider 7 and the second cam portion 18 of the second slider 8 engage from the proximal end of the cam to the distal end (the "distal and proximal" of the proximal and distal ends refers to the distal and proximal direction close to the middle of the sliding plate), the first connecting shaft 19 and the second connecting shaft 20 perform a predetermined arc-shaped movement in the first rail 13 and the second rail 14, respectively, and the first connecting portion 25 and the second connecting portion 26 horizontally slide in the third sliding groove 23 and the fourth sliding groove 24, respectively, in the direction close to the support mechanism. Meanwhile, the first rotating member 5 and the second rotating member 6 of the supporting mechanism slide horizontally in the first sliding groove 21 and the second sliding groove 22 of the supporting member in the direction close to the middle supporting mechanism. The motion process of the two cam parts from the near end to the far end is a compensation process of length increase, and the damage caused by the excessive extrusion of the screen can be effectively prevented.
Similarly, during the process from unfolding to folding, the first support 2 and the second support 3 start to rotate and approach each other, at this time, the first cam portion 17 of the first slider 7 and the second cam portion 18 of the second slider 8 start to engage from the distal end to the proximal end of the cam portions, the first connecting shaft 19 and the second connecting shaft 20 respectively make a predetermined arc motion in the first rail 13 and the second rail 14, and the first connecting portion 25 and the second connecting portion 26 respectively horizontally slide in the third sliding groove 23 and the fourth sliding groove 24 in the direction away from the support mechanism. Meanwhile, the first rotating member 5 and the second rotating member 6 of the supporting mechanism slide horizontally in the first sliding groove 21 and the second sliding groove 22 of the supporting member in the direction away from the supporting mechanism. The motion process of the two cam parts from the far end to the near end is a compensation process of length shortening, and the damage caused by excessive pulling of the screen can be effectively prevented.
