Optionally, the extension extends in a straight line towards a direction away from the base.

As an implementation manner, the folding mechanism of the embodiment of the present application is applied to a mobile terminal having a flexible screen. Optionally, the base 10 and the support 20 are used to support the flexible screen 40. Optionally, the mobile terminal includes a flexible screen 40, the flexible screen 40 is disposed on the opposite side of the support 20 along the protruding direction of the bending portion 21, the flexible screen 40 includes two first regions 41 and a second region 42 connected between the two first regions 41, the first regions 41 are attached and fixed to the corresponding extending portions 22 of the support 20, and the second region 42 abuts against the base 10.

Alternatively, the number of the supporting members 20 is exemplified as two. Because the flexible screen 40 is of a sheet structure, in order to effectively support the flexible screen 40, the two supporting members 20 may be of a sheet structure, the extending portions 22 of the two supporting members 20 are respectively attached and fixed to the two first regions 41 of the flexible screen 40, and the area size of the extending portion 22 of the supporting member 20 may be adapted to the area size of the first region 41 of the flexible screen 40. Alternatively, the base 10 may be a movable plate-like structure, and the area size of the base 10 when unfolded may be adapted to the area size of the second region 42 of the flexible screen 40, so as to effectively support the flexible screen 40 when the flexible screen 40 is completely unfolded.

The folding mechanism is switchable between a first state and a second state, when the folding mechanism is in the first state, the flexible screen 40 is in a folded state; when the folding mechanism is in the second state, the flexible screen 40 is in the unfolded state.

Alternatively, as shown in fig. 2, when the folding mechanism is switched from the second state to the first state, the supporting members 20 rotate around one end close to the base 10 as a fulcrum, so that the two supporting members 20 in the unfolded state are closed inwards around the base 10 as a center, the two supporting members 20 drive the flat flexible screen 40 to fold, the bending degree of the second region 42 of the flexible screen 40 gradually increases, and the accommodating cavity 211 is formed due to the bending of the bending portion 21 of the supporting member 20. When the two supporting members 20 approach each other, the openings of the two accommodating cavities 211 are opposite, the two accommodating cavities 211 are combined to form a complete accommodating space, and the second region 42 of the flexible screen 40 can be bent along the cavity wall of the accommodating cavity 211, so that the convex second region 42 of the flexible screen 40 is accommodated in the accommodating space after the flexible screen 40 is bent.

At this time, the two first regions 41 and the second region 42 of the flexible screen 40 are spread out in a line and are respectively laid on the extension portions 22 of the two support members 20 and the base 10, and finally, the flexible screen 40 is converted into a flat state, the first regions 41 of the flexible screen 40 are respectively supported by the extension portions 22 of the two support members 40, and the second region 42 of the flexible screen 40 is supported by the base 10.

When the two supporting members 20 are rotated relatively, the openings of the accommodating cavities 211 formed by bending the two bending parts 21 are opposite. In this way, the flexible screen 40 can be driven to convert from the unfolded state to the folded state, and the flexible screen 40 can be bent along the cavity wall of the accommodating cavity 211, so that the convex part of the flexible screen 40 after bending is accommodated in the accommodating cavity 211; when the two supporting members 20 rotate back to back, the extending portions 22 of the two supporting members 20 and the base 10 are in the same plane, so that the flexible screen 40 is driven to be converted from the folded state to the unfolded state, and the extending portions 22 of the two supporting members 20 and the base 10 can effectively support the unfolded flexible screen 40.

Alternatively, when the folding mechanism is switched from the second state to the first state, the two movable tables 11 move away from each other, and the two movable tables 11 move apart to different parts of the second region 42 of the flexible screen 40. At this moment, the carrying table 12 moves towards the direction close to the gear 30 and moves to between the two movable tables 11, so that the carrying table and the two movable tables 11 are located on the same plane, the supporting area of the combination of the movable tables 11 and the carrying table 12 is increased, more uniform supporting force can be provided for the flexible screen 40, the flatness of the flexible screen 40 can be guaranteed, and the touch and viewing experience of a user is improved. Alternatively, the movement of the receiving table 12 may be driven by a driving member, which is not limited herein.

Optionally, referring to fig. 1 to 2, the receiving platform 12 is provided with a first guiding inclined plane 12 corresponding to a side edge of the movable platform 11, and the movable platform 11 is provided with a second guiding inclined plane 114 corresponding to the first guiding inclined plane 12 corresponding to a side edge of the receiving platform 12; when at least two movable tables 11 approach each other, the receiving table 12 slides to the side of the movable table 11 away from the gear 30 by the relative sliding of the first guide slope 12 and the second guide slope 114.

Alternatively, the width of the surface of the receiving table 12 on the side facing the gear 30 is smaller than the width of the surface of the receiving table 12 on the side facing away from the gear 30, so that the receiving table 12 forms the first guiding slope 12 at the junction of the two surfaces. Optionally, the width of the first surface of the movable table 11 is larger than that of the second surface, so that the two movable tables 11 form a second guiding inclined surface 114 at the junction of the first surface and the second surface, and the first guiding inclined surface 12 and the second guiding inclined surface 114 are matched. By means of the relative sliding of the first guiding inclined surface 12 and the second guiding inclined surface 114, when the two movable tables 11 approach each other and press the receiving table 12, the receiving table 12 can move in the direction away from the gear 30, so that the receiving table 12 and the two movable tables 11 can be automatically switched from the side-by-side position relationship to the overlapped position relationship, and the switching between the folded state and the unfolded state of the flexible screen 40 can be realized. Moreover, the matching structure is simple, the size of the folding mechanism is favorably reduced, and the assembly difficulty and the manufacturing process are favorably simplified.

When the folding mechanism is switched from the second state to the first state, the two movable tables 11 approach each other and press the receiving table 12, so that the receiving table 12 moves in a direction away from the gear 30. At this time, the elastic member is in a stretched state, and the receiving table 12 is closely attached to the two movable tables 11 which are close to each other under the tensile force of the elastic member. So, can shorten the area occupied of whole base 10, make two movable tables 11 and accept platform 12 all hold in two accommodation cavity 211 to closing the accommodation space who forms to reduce thickness and volume when folding mechanism is in fold condition, promote mobile terminal's portability.

At the same time, the elastic element is reset, so that the receiving table 12 moves between the two movable tables 11 and is in the same plane with the two movable tables 11. The supporting area of the combination of the movable table 11 and the bearing table 12 is increased, more uniform supporting force can be provided for the flexible screen 40, and the flatness of the flexible screen 40 can be guaranteed so as to improve the touch and viewing experience of a user. Therefore, by arranging the elastic member, the automatic switching from the overlapped position relationship to the side-by-side position relationship between the receiving table 12 and the two movable tables 11 can be realized, and the folding mechanism has a simple structure, is beneficial to reducing the volume of the folding mechanism, and is also beneficial to simplifying the assembly difficulty and the manufacturing process.

Optionally, referring to fig. 1 to 2, a limiting member 122 is disposed on the receiving platform 12, and the limiting member 122 is matched with the housing of the mobile terminal to limit the receiving platform 12 to move only along a direction perpendicular to the movable platform 11.
