The embodiment of the application provides an electronic device, the electronic device comprises a flexible screen 15, a supporting component and a connecting component 13. Wherein the support assembly comprises a fixed body 111, a first moving body 112 and a second moving body 113, the first moving body 112 and the second moving body 113 are respectively arranged at two opposite sides of the fixed body 111, and the first moving body 112 and the second moving body 113 are both movably connected with the fixed body 111, so that, while the fixed body 111 remains stationary, the first moving body 112 and the second moving body 113 can move with respect to the fixed body 111, and thus the relative position between the first moving body 112 and the second moving body 113, may also be varied, optionally, when the first moving body 112 moves with respect to the fixed body 111, the second moving body 113 may be fixed, when the second moving body 113 moves with respect to the fixed body 111, the first moving body 112 may be fixed differently, of course, the first moving body 112 and the second moving body 113 may also move simultaneously with respect to the fixed body 111; the flexible screen 15 is disposed on the supporting assembly, and the supporting assembly provides a supporting force, and when the first moving body 112 and/or the second moving body 113 moves relative to the fixed body 111, the flexible screen 15 can be unfolded or folded.
Optionally, the first moving body 112 and the second moving body 113 are both provided with an accommodating space therein, the flexible screen 15 is disposed on the support assembly, a first portion of the flexible screen 15 is fixedly connected with the fixed body 111, a second portion of the flexible screen 15 is in sliding fit with the first moving body 112, and a third portion of the flexible screen 15 is in sliding fit with the second moving body 113, that is, when the flexible screen 15 is in a folded state, the flexible screen 15 is partially rolled in the accommodating space of the first moving body 112 and the second moving body 113, for example, a middle region (the first portion) of the flexible screen 15 is opposite to the fixed body 111 and supported by the fixed body 111, and two side regions (the second portion and the third portion) of the flexible screen 15 are at least partially rolled in the accommodating space of the first moving body 112 and the second moving body 113, where the rolling may be from a first side of the first moving body 112/the second moving body 113 to a first side opposite to the first side of the first moving body 112/113 And when the first moving body 112 and/or the second moving body 113 move relative to the fixed body 111, the second portion and/or the third portion of the flexible screen 15 can be driven to unfold or fold.
In some optional real-time manners, in order to realize the movement of the first moving body 112 and the second moving body 113, the electronic device may further include a driving mechanism 12, the driving mechanism 12 is connected to the first moving body 112 and the second moving body 113, respectively, the driving mechanism 12 may drive the first moving body 112 and the second moving body 113 to make a linear motion relative to the fixed body 111, so as to drive the flexible screen 15 to switch between the unfolded state and the folded state, that is, the driving mechanism 12 may drive the first moving body 112 and the second moving body 113 to make a motion away from or towards the fixed body 111, so that the first moving body 112 and the second moving body 113 may drive a portion of the flexible screen 15 supported and wound thereon to unfold or fold on two sides of the fixed body 111; it can be known that the display area of the flexible screen 15 that can be seen by the user in the unfolded state is larger than the display area of the flexible screen 15 that can be seen by the user in the folded state, and the portion of the flexible screen 15 that can be seen in the folded state is usually fixed; alternatively, the driving mechanism 12 may drive only one of the first moving body 112 and the second moving body 113 to move, or drive the first moving body 112 and the second moving body 113 to move simultaneously, that is, the electronic device may unfold the flexible screen 15 only to one side, or unfold the flexible screen 15 to both sides simultaneously.

In case that the first and second moving bodies 112 and 113 move with respect to the fixed body, the first bracket 132 may rotate with respect to the fixed body 111 to wind or release the flexible circuit board 131, and then the distance between the first and second devices 141 and 142 may be matched to the length of the unwound portion of the flexible circuit board 131, thereby securing a stable connection between the first and second devices 141 and 142.
Since the first device 141 is connected to the first moving body 112 and is movable with the movement of the first moving body 112, and the second device 142 is connected to the second moving body 113 and is movable with the movement of the second moving body 113, the distance between the first device 141 and the second device 142 will also change during the movement of the first moving body 112 and the second moving body 113 relative to the fixed body 111, and the length of the flexible circuit board 131 needs to be at least equal to the maximum distance between the first device 141 and the second device 142 in order to ensure the communication between the first device 141 and the second device 142.
If the scheme in the prior art is adopted, that is, the length of the flexible circuit board 131 connecting the first device 141 and the second device 142 is fixed, when the distance between the first device 141 and the second device 142 is smaller than the maximum distance, redundancy occurs in the flexible circuit board 131, which causes problems of disordered internal structure space due to stacking of too long portions of the flexible circuit board 131 inside the electronic device, excessive bending damage of the flexible circuit board 131, erroneous contact and the like.

The coil spring 133 is wound on the first bracket 132 and connected to the second bracket 134 to provide a restraining force, that is, the force of the coil spring 133 acts on the flexible circuit board 131, so that the flexible circuit board 131 is always in a compact state during the winding or releasing process, thereby ensuring the stability of the internal structure of the flexible screen 15 of the electronic device during the unfolding or folding process.
