Detailed Description
Reference is made to the accompanying drawings. The hinge provided by the utility model comprises a left rotating support 1 and a right rotating support 2, wherein the left rotating support 1 and the right rotating support 2 can respectively rotate by taking a first axis and a second axis as axes, the first axis and the second axis are parallel, and the axes of the left rotating support 1 and the right rotating support 2 are respectively a first axis 10 and a second axis 20 which are real axes. A synchronous reverse rotation connecting mechanism (such as a gear mechanism 6) is connected between the left rotating bracket 1 and the right rotating bracket 2 to synchronously reverse rotation in the hinge opening and closing process.
The hinge is also provided with a middle rotating support part 3; the middle rotary supporting part 3 corresponds to the position of the middle housing 100 of the internally folded flexible screen mobile terminal. The middle rotating support component 3 and the left rotating support 1 are both sleeved on the first shaft 10, the left rotating support 1 and the first shaft 10 are connected together through flat positions to rotate synchronously, and the shaft hole 30 of the middle rotating support component 3 is a round hole and is connected with the first shaft 10 in a rotating mode; the right rotating bracket 2 is sleeved on the second shaft 20, and the right rotating bracket 2 and the second shaft 20 are connected together through a flat position to synchronously rotate.
When the mobile terminal is unfolded and flat, the middle rotating support part 3 is also rotated to be in flattening fit with the right rotating support 2 so as to support the flexible screen, and the side 31 of the middle rotating support part 3 close to the left rotating support 2 exceeds the central line of the middle shell 100 of the mobile terminal and is jointed with the right rotating support 2; the side 21 of the right turning bracket 2 adjacent to the left turning bracket 1 is suitably widened closer to the middle line of the middle housing 100 than the side 12 of the left turning bracket adjacent to the second turning bracket. Thus, when the middle rotation support member 3 rotates downward, before the middle rotation support member is limited, the middle rotation support member rotates synchronously in the same direction as the left rotation support and rotates synchronously in the opposite direction as the right rotation support, but the rotation radius of the side 31 of the middle rotation support member 3 is larger than the rotation radius of the side 21 of the right rotation support, so that the rotation linear speed of the side 31 is larger than the rotation radius of the side 21, and once the middle rotation support member rotates, the middle rotation support member and the right rotation support member can be staggered immediately, thereby the width of the gap 101 between the middle rotation support member and the right rotation support member can be more effectively reduced, and the gap becomes very thin.
Further, the end face 210 of the second pivot mounting on this side 21 can be angled back inwards, which enables a further reduction of the slot width 101.
The left rotating bracket 1 is provided with a supporting part 11 of the middle rotating supporting part 3 when the hinge is opened to be flat, so that the middle rotating supporting part 3 obtains rigid support to stably support the flexible screen when the hinge is flat.
The middle rotation supporting component 3 is connected with an elastic component 5, when the hinge is folded, the elastic component 5 drives the middle rotation supporting component 3 to rotate downwards and turn into the middle shell 100 of the mobile terminal.

When the hinge is folded, the intermediate rotary supporting member 3 is driven by the elastic member 5 to rotate downward into the middle housing 100 of the mobile terminal until stopped by a stopper, which may be provided in the middle housing. In the process from hinge flattening to hinge folding, the rotation angles of the middle rotating support part 3 are respectively smaller than the rotation angles of the left rotating support 1 and the right rotating support 2; in the motion process from folding to flattening of the hinge, when the hinge rotates to the left rotating support 1, the supporting part 11 contacts the middle rotating supporting part 3, the supporting part 11 drives the middle rotating supporting part 3 to rotate to the flexible screen supporting position, and in the flexible screen supporting position, the elastic part 5 presses the middle rotating supporting part 3 on the supporting part 11.
The hinge is unfolded and folded, and the corresponding inward-folding mobile terminal is in the state of unfolding and folding. The middle rotary supporting part 3 can be a plate-shaped direct supporting flexible screen, or supporting plates are respectively fixed on the left middle rotary supporting part 3 to support the flexible screen. At this time, the support plate is also regarded as a part of the intermediate rotation support member 3.
Flexible screen mobile terminal of infolding includes middle part casing 100, left side casing, right side casing and inboard flexible screen, the left side rotate support 1 and right side rotate support 2 respectively with left side casing, right side casing rotation direction have the restraint to be connected, left side casing, right side casing use primary shaft 10 and secondary shaft 20 respectively as its axis of rotation, left side casing, right side casing set up the backup pad of inboard flexible screen respectively.
