Correspondingly, the shaft 153b is pivotally connected to the second body 120 and does not move relative to the second body 120, and the other shafts 153c have different corresponding relationships according to the structure of the connecting member 152. Further, the chain body 151 and the shafts 153a to 153c are arranged between the first body 110 and the second body 120 along a path L1 (an arc line with a dashed double arrow is illustrated in fig. 3), the shafts 153a to 153c are respectively and correspondingly inserted into the chain body 151, the connecting members 152 are located at two opposite sides of the chain body 151 (as shown in fig. 2), each connecting member 152 is pivotally connected to the two adjacent shafts 153a to 153c, each connecting member 152 has a hole 152a, and one of any two adjacent shafts 153a to 153c is pivotally connected to the hole 152 a. Meanwhile, the flexible chain assembly 150 is connected to the first portion 131 of the flexible screen 130 through a connecting member 170 (a connecting member), so that the flexible screen 130 can be linked with the extension or contraction of the flexible chain assembly 150, thereby compensating for the size difference between the folded state and the flattened state of the flexible screen 130.

Fig. 5 is a partially enlarged view of the foldable electronic device of fig. 4 in another state, wherein the foldable electronic device 100 is shown in an unfolded state. Referring to fig. 3 and 5, in the present embodiment, it can be clearly understood that the curved path L1 shown in fig. 4 is also converted into a straight line when the unfolded state shown in fig. 5 is converted.
It should be noted that, based on the above-mentioned configuration, when the foldable electronic device 100 rotates through the rotating shaft assembly 140, i.e. it is switched between the folded state shown in fig. 4 and the unfolded state shown in fig. 5, as the link mechanism 160 is switched from the bent state shown in fig. 4 to the extended state shown in fig. 5, the first end E1 and the shaft 153a of the flexible chain assembly 150 move in the first body 110, and the moving distance is the sum of the moving distances of the shafts 153a and 153c in the counterbore 152a at the counterbore 152a, so as to form the stretching stroke generated by the flexible chain assembly 150, and at the same time, the flexible screen 130 is pulled apart and flattened through the connecting member 170, so that the flexible screen 130 is in a flattened and linear state along with the flexible chain assembly 150 in the unfolded state, and the third portion 133 of the flexible screen 130 is suspended between the first body 110 and the second body 120, and bears against a linear portion of the telescopic chain assembly 150. Conversely, when the retractable chain assembly 150 is converted from the extended state to the folded state, the linking flexible screen 130 can be converted from the flat state to the folded state.
In this way, the foldable electronic device 100 can smoothly compensate for the bending deformation of the flexible screen 130 during the transition between the folded state and the unfolded state, that is, the arc shape formed by the flexible screen 130 in the folded state can be effectively eliminated when the flexible screen 130 is transitioned to the unfolded state. That is, during the conversion between the folded state and the unfolded state, the shaft 153c pivotally connected to the enlarged hole 152a and the shaft 153a move between the two opposite ends of the enlarged hole 152a to form the telescopic stroke.
In summary, in the above embodiments of the present invention, the foldable electronic device is configured by the flexible chain assembly connected between the two bodies and the link mechanism disposed between the rotating shaft assembly and the bodies, so that the pivot joint of the connecting rod mechanism and the telescopic chain component can slide in one machine body in the process of converting the folded state and the unfolded state of the two machine bodies, thereby driving the retractable chain assembly to generate a retractable state change, and the retractable stroke thereof is used for compensating the size difference generated in the conversion process of the flexible screen, which can make the arc shape of the flexible screen in the folded state be smoothly eliminated when the flexible screen is converted to the unfolded state, and make the flexible screen in the unfolded state present a flat linear profile, thereby effectively avoiding the buckling or damage of the flexible screen and prolonging the service life of the flexible screen.
