In the embodiment of the present application, the first housing 10 and the second housing 20 are used for carrying the flexible screen 30 and other necessary functional components, and the pivot mechanism 40 is provided for achieving a rotational connection between the first housing 10 and the second housing 20, thereby achieving folding or unfolding of the flexible screen 30. The flexible screen 30 includes a first sub-screen 31, a second sub-screen 32 and a bending portion 33, the first sub-screen 31 is installed on the first casing 10, the second sub-screen 32 is installed on the second casing 20, and the bending portion 33 is located between the first sub-screen 31 and the second sub-screen 32, so that the connection between the first sub-screen 31 and the second sub-screen 32 is realized. The telescopic supporting mechanism 50 is rotatably connected to the rotating shaft mechanism 40, and is driven by the rotating shaft mechanism 40 to perform telescopic movement along with the rotation of the rotating shaft mechanism and switch between the first position and the second position of the rotating shaft mechanism 40. When the electronic device is in the folded state, the telescopic support mechanism 50 is in the contracted state, and forms a gap with the bent portion 33, and is in the first position; when the electronic apparatus is in the unfolded state, the telescopic support mechanism 50 is in the unfolded state and in the second position, and abuts against the bent portion 33 to support the bent portion 33. The problem that the size of the screen is insufficient or too large due to different rotating radiuses in the process of folding the flexible screen 30 is avoided, and the screen is prevented from being scratched and folded.

It should be noted that, during the process of switching the electronic device from the folded state to the unfolded state, the telescopic supporting mechanism 50 moves towards the direction close to the bent portion 33 until abutting against the bent portion 33, so as to provide a supporting function for the flexible screen 30.

When electronic equipment is in the condition of expansion state, first rotating member 412 is synchronous rotation under gear engagement, it slides in the groove of first rotating member 412 to drive guide block 4141, thereby it inwards slides along frame 43 axial direction to drive first sleeve 4111, wedge 4112 also inwards slides this moment, thereby it is ejecting with the casing, wedge 4112 and driven part are rotatory to both sides simultaneously, outside slip of casing in expansion process has been realized, and flexible screen 30 glues together with the casing, thereby the exhibition of flexible screen 30 has been realized, the fold phenomenon has been avoided appearing, and simultaneously, flexible supporting mechanism 50 is in support state, give the screen supporting role.

When the electronic device is in the folded state and the first sub-screen 31 and the second sub-screen 32 are separately overlapped, the flexible screen 30 is turned inside out. The first rotating member 412 rotates synchronously under the gear engagement to drive the guide block 4141 to slide in the oblique groove of the first rotating member 412, so as to drive the sleeve to slide outwards along the axial direction of the rack 43, at this time, the wedge block 4112 also slides outwards, under the action of the spring module, the roller 4132 keeps constant contact with the wedge block 4112, at this time, the roller 4132 rolls along the wedge block 4112, meanwhile, the wedge block 4112 rotates inwards with the roller 4132, the housing is pulled back inwards by the spring module, the inward sliding of the housing in the closing process is realized, the flexible screen 30 is prevented from being damaged by pulling in the folding process, the folding of the flexible screen 30 is realized, meanwhile, the telescopic support mechanism 50 extends transversely and contracts longitudinally under the drive of the first rotating member 412, and the interference between the telescopic support mechanism 50 and the screen is avoided.

When the electronic device is in the folded state and the first sub-screen 31 and the second sub-screen 32 are in abutting overlap, the flexible screen 30 is folded inward. First rotating member 412 is synchronous rotation under gear engagement, it slides in the horizontal slot of first rotating member 412 to drive guide block 4141, first sleeve 4111 does not take place the motion this moment, wedge 4112 and driven member inboard rotation simultaneously, because first sleeve 4111 does not take place the motion, consequently wedge 4112 and gyro wheel 4132 keep relative static, therefore frame 43 does not take place the motion, the problem of accomodating of flexible screen 30 when only needing to consider infolding this moment, flexible supporting mechanism 50 is under the effect of first rotating member 412, transversely shrink, vertically also shrink, the accomodating of flexible screen 30 has been realized, the folding seal problem of flexible screen 30 infolding in-process owing to the storage space is not enough aroused has been solved, the infolding of pivot mechanism 40 has been realized.

This application drives the horizontal flexible of flexible supporting mechanism 50 through the rotation of first rotatable part 412 to drive flexible supporting mechanism 50 and go up and down, solved flexible screen 30 in the folding process because the not enough crease problem that arouses of accommodation space, at mobile terminal when the exhibition is flat simultaneously, give flexible screen 30 sufficient support, realized mobile terminal's infolding.

This application drives first equivalent cam at frame 43 axial direction's linear motion through the rotation of first rotating part 412 to drive the flexible of second equivalent cam in frame 43 radial direction, realized the flexible of casing at the folding in-process of intelligent terminal, solved flexible screen 30 outer folding in-process because the different screen size that leads to the fact of turning radius is not enough or too big problem, avoid the screen to strain, the fold, mobile terminal's outer book has been realized.

The rotating shaft mechanism 40 is of a splicing type, namely the first rotating part 412 and the rack 43 are not designed integrally, when the folding structure is mechanically damaged, the damaged parts can be detached, replaced and maintained, the whole rotating shaft mechanism 40 does not need to be maintained, and the after-sale maintenance cost of a user is reduced; meanwhile, due to the splicing design, the structure and the material of each part can be optimized when the specific part is designed, and the weight of the whole mechanism is favorably reduced.

The first rotating part 412 applied in the application is in gear engagement, and can apply certain damping to realize that the folding screen stops at any angle.

The hinge mechanism 40 of the present application is applicable to mobile phones, notebook computers, tablet computers, electronic books, and the like, and may be other mobile terminals. The scheme of adopting two equivalent cam mechanisms to realize the single-side and double-side contraction movement of the outer folding screen, the scheme of adopting the telescopic supporting mechanism 50 to solve the storage problem of the flexible screen 30 to realize inward folding, and the scheme of simultaneously realizing inward and outward folding through the two schemes are within the protection scope of the patent of the invention.
