The flexible screen 30 includes a bendable area 31 corresponding to the folding device 50 and two non-bending areas 33 connected to opposite sides of the bendable area 31.

When the first shell 21 and the second shell 23 are folded with each other, the light inlet of the camera 60 is opposite to the light-transmitting area 230. In some embodiments, the camera 60 is arranged in the second shell 23, and the first shell 21 is provided with a light-transmitting area. When the first shell 21 and the second shell 23 are folded with each other, the light inlet of the camera 60 is opposite to the light-transmitting area.

Therefore, the camera 60 of the electronic device 100 can take selfies in the flattened state or the fully folded state, which is not only convenient for shooting, but also reduces the number of cameras and reduces the manufacturing cost. In addition, the thickness of the electronic device 100 is not limited by the height of the front camera, which can reduce the overall thickness of the electronic device 100.

[0058] like Figure 7-Figure 15The folding device 50 includes a folding-assisting component 51 and a bendable component 52 connected to the folding-assisting component 51. The folding-assisting component 51 includes a base 54, a rotating mechanism 55, a linkage mechanism 56 and a limiting mechanism 57; the rotating mechanism 55 includes a rotating member 550 rotatably connected to the base 54 and a connecting member 555. The end of the rotating member 550 away from the base 54 is rotatably connected to the connecting member 555 through a rotating shaft 551. The linkage mechanism 56 includes a pair of rotating shafts 561 connected to the base 54, a first connecting rod 562, a second connecting rod 563 and a gear assembly 564; the first connecting rod 562 and the second connecting rod 563 are respectively connected to the pair of rotating shafts 561, and the gear assembly 564 is arranged between the first connecting rod 562 and the second connecting rod 563, and the first connecting rod 562 and the second connecting rod 563 are respectively connected to the two rotating mechanisms 55 in a sliding manner; the gear assembly 564 includes a synchronous gear 5642, a first driving gear 5643 and a second driving gear 5645, the first driving gear 5643 is arranged on the first connecting rod 562 and meshed with the synchronous gear 5642, and the second driving gear 5645 is arranged on the second connecting rod 563 and meshed with the synchronous gear 5642; the limiting mechanism 57 includes a damping member 570, a first connecting rod ... The push member 572, the supporting member 573, the elastic member 575, the positioning member 576 and the friction assembly 577 on the member 562; the push member 572, the supporting member 573, the elastic member 575, the positioning member 576 and the friction assembly 577 are sleeved on the rotating shaft 561, and the opposite ends of the elastic member 575 elastically abut against the supporting member 573 and the positioning member 576 respectively; the damping member 570 is arranged between the synchronous gear 5642 and the positioning member 576; when the first connecting rod member 562 and / or the second connecting rod member 563 rotate around the axis of the corresponding rotating shaft 561, the first driving gear 5643 and / or the second driving gear 5645 drive the synchronous gear 5642 to rotate relative to the damping member 570, and there is a friction resistance between the synchronous gear 5642 and the damping member 570 to hinder the rotation of the synchronous gear 5642. That is, when one of the rotating mechanisms 55 or the two rotating mechanisms 55 rotate relative to the base 54, the first connecting rod 562 and the second connecting rod 563 rotate along the axis of the two rotating shafts 561 respectively, so that the push member 572 rotates relative to the supporting member 573, and the friction torque between the push member 572 and the supporting member 573, the friction resistance of the friction assembly 577, and the friction resistance between the synchronous gear 5642 and the damping member 570 position the first connecting rod 562, the second connecting rod 563 and the two rotating mechanisms 55 relative to the base 54.

[0059] The folding-assisting component 51 is arranged on the back side of the bendable component 52. The bendable component 52 is folded or unfolded along with the folding-assisting component 51. The friction torque between the pushing member 572 and the supporting member 573, the friction resistance of the friction component 577, and the friction resistance between the synchronous gear 5642 and the damping member 570 enable the bendable component 52 to be positioned during the folding or unfolding process, so as to realize that the first shell 21 and the second shell 23 are positioned to a specific angle relative to the base 54, thereby allowing the electronic device 100 to have a hovering effect.

[0060] There is at least one folding aid component 51 on the back of the bendable component 52. In this embodiment, there are two folding aid components 51, which are respectively arranged at two opposite ends of the back of the bendable component 52. The bendable component 52 includes a middle support hinge 521 and two side support hinges 523 connected to opposite sides of the middle support hinge 521. The two side support hinges 523 are respectively movably connected to two rotating mechanisms 55 and two first connecting rods 562. The back of the flexible screen 30 is attached to the front of the middle support hinge 521 and the side support hinge 523. One of the rotating mechanisms 55 rotates relative to the base 54, and drives the other rotating mechanism 55 to rotate synchronously relative to the base 54 through the linkage mechanism 56, so as to realize the synchronous unfolding or synchronous bending of the bendable component 52. During the folding or unfolding process of the folding device 50, the two rotating mechanisms 55 rotate synchronously relative to the base 54, the first connecting rod 562 and the second connecting rod 563 rotate synchronously relative to the base 54, and at the same time, the first connecting rod 562 and the second connecting rod 563 slide respectively relative to the two rotating mechanisms 55, and the first driving gear 5643 on the first connecting rod 562 and the second driving gear 5645 on the second connecting rod 563 rotate around the axes of the two rotating shafts 561 respectively to rotate the synchronous gear 5642; the friction torque between the push member 572 and the supporting member 573, the friction resistance of the friction assembly 577, and the friction resistance between the synchronous gear 5642 and the damping member 570 can position the side support hinge 523 relative to the middle support hinge 521, so that the first shell 21 and the second shell 23 are relatively positioned to a specific angle, thereby achieving a better hovering effect of the electronic device 100. The bendable component 52 of the folding device 50 can achieve multi-angle limitation during the process of bending or flattening, so that the flexible screen 30 attached to the bendable component 52 can achieve multi-angle limitation during the process of bending or flattening with the bendable component 52, which is convenient to use and improves the user experience. Secondly, the folding device 50 increases the friction resistance of folding or flattening without adding components, improves the hovering effect of the folding device, thereby improving the hovering effect of the electronic device 100, and is conducive to the miniaturization of the folding device.

[0083] When the linkage mechanism 56 is bent from a completely flattened state, the first link member 562 is bent toward the second link member 563 relative to the supporting member 573, and the first link member 562 rotates along the axis of the corresponding rotating shaft 561 to drive the corresponding rotating shaft 561, the first driving gear 5643 and the corresponding pushing member 572 to rotate along the axis of the rotating shaft 561, and the rotating shaft 561 rotates in the second guide slide hole 5765 corresponding to the positioning member 576, the first guide slide hole 5652 corresponding to the fixing member 565 and the through hole 5782 corresponding to the gasket 578; the rotating first driving gear 5643 drives the second driving gear 5645 to rotate through the synchronous gear 5642, and the rotation of the second driving gear 5645 drives the corresponding rotating shaft 561, the second sleeve 5632 and the second link 5633 to rotate, so as to achieve the desired effect. This causes the first connecting rod member 562 and the second connecting rod member 563 of the linkage mechanism 56 to move synchronously toward each other; at the same time, the pushing member 572 on the first connecting rod member 562 and the pushing member 572 on the second connecting rod member 563 rotate relative to the supporting member 573, respectively, so that the first cam 5720 and the second cam 5722 respectively rotate to push the two third cams 5730, and the supporting member 573 slides axially along the rotating shaft 561 to squeeze the elastic member 575, and the elastic member 575 elastically pushes the positioning member 576, so that the first friction member 5770 is clamped between the gasket 578 and the positioning member 576 and the second friction member 5775 is clamped between the gasket 578 and the buckle 5779, and the first friction member 5770 and the second friction member 5775 rotate relative to the positioning member 576 and the gasket 578 along the corresponding rotating shaft 561.
