Detailed Description

Reference is made to the accompanying drawings. The utility model provides a spring motion for the spring motion in the flexible screen mobile terminal hinge.

The spring motion mechanism comprises a moving part 1 and a second part 2, wherein the moving part 1 is a supporting plate on one side of the flexible screen, and when the moving part is positioned on the left side of the hinge, the moving part is a left supporting plate, and when the moving part is positioned on the right side, the moving part is a right supporting plate, or the moving part is a part connected with the supporting plate.

A W-shaped spring 3 is arranged between the movable piece 1 and the second component 2, two

ends

31 and 32 of the W-shaped spring are rotatably connected with the movable piece, and a middle concave part 33 of the W-shaped spring is fixedly connected with the second component 2.

The rotary connection can adopt a rivet 5 which is used for connecting two ends of the W-shaped spring to be fixed on the movable part 1, so that the spring arms at two ends of the spring can do rotary motion by taking the rivet 5 as an axis; the central recess 33 of the W-shaped spring is fixedly connected to the second part 2 by welding, and reference numeral 34 denotes a pressing plate at the central portion of the spring connected to the movable element. The utility model discloses be different from W spring in the past, through changing both ends fixed point centre of a circle production force value, can move behind the second part atress, the direction of motion is perpendicular with both ends fixed department centre of a circle line.

The utility model discloses a W shape spring is in compression state all the time being applied to flexible screen mobile terminal hinge, and occupation space is little, and the power value of production is big, and in the short stroke. The force value does not fluctuate much, and as shown in fig. 4, in the present embodiment, the movement stroke (i.e., the change in the distance from the connecting point of the concave portion 33 and the second member 2 to the connecting line between the two

ends

31, 32 of the W-shaped spring and the center point of the pivotal connection of the movable member) is only 4.07 mm.

The second part 2 is a part which is connected with the movable part in a sliding way, or is a spring push plate. In this embodiment, the second component 2 is a spring push plate, one end 21 of the spring push plate is rotatably connected to the middle supporting structure 6 of the hinge, the movable member 1 is slidably connected to the connecting member 7, one end 71 of the connecting member 7 is rotatably connected to the middle supporting structure 6, and the connecting member 7 is rotatably connected to the middle supporting structure 6 along an axis parallel to an axis of the spring push plate and the middle supporting structure of the hinge.

When the second part is a part which is connected with the movable part in a sliding way, the second part (at this time, the second part can adopt the connecting piece 7) is positioned between the movable part and the middle supporting structure of the hinge, and the second part is connected with the middle supporting structure in a rotating way.

The mountable of moving part 1 can rotate for support frame 4 on support frame 4, support frame 4 is the structure of connecting mobile terminal one side casing in the hinge, support frame 4 rotates with middle bearing structure 6 to be connected, in the hinge closure to the opening process, support frame 4 and moving part 1 are rotatory around middle bearing structure 6, the distance of the relative middle bearing structure 6 of rotation tie point at W shape spring both ends can change (the distance that the flexible screen of distance change matching is crooked to the mobile terminal mechanical structure required compensation when flattening out, generally only a few millimeters) — distance change order: distal-proximal-distal (as does the process from opening to closing), the W-spring provides pressure throughout. Because the utility model discloses an among the spring motion, can keep spring force value big, the power value is undulant little in short stroke, this pressure can help solving flexible screen mobile terminal and locate the problem that keeps its closed state when the closed state, and help and torsion mechanism cooperation, obtains better operation and feels.

The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art is in the field of the present invention, and all the changes or modifications are covered in the protection scope of the present invention.
