Detailed ways

Refer to attached drawings. The spring motion mechanism provided by the utility model is a spring motion mechanism in a hinge of a flexible screen mobile terminal.

The spring motion mechanism includes a movable part 1 and a second part 2. The movable part 1 is a support plate on one side of the flexible screen. When it is on the left side of the hinge, it is the left support plate and is on the right side. is the right support plate, or the movable piece is a component connected to the support plate.

A W-shaped spring 3 is arranged between the movable part 1 and the second part 2 , the two ends 31 and 32 of the W-shaped spring are rotatably connected with the movable part, and the middle recess 33 of the W-shaped spring is connected to the second part 2 . Fixed connection.

For the rotational connection, the rivets 5 that connect the two ends of the W-shaped spring to the movable member 1 can be used, so that the spring arms at both ends of the spring can use the rivets 5 as the axes to perform rotational motion; the middle concave part of the W-shaped spring 33 can be fixedly connected with the second part 2 by welding, and the reference numeral 34 is the pressing plate of the middle part of the spring connected with the movable part. The utility model is different from the previous W spring, by changing the force value generated by the center of the fixed point at both ends, the second component will move after being stressed, and the movement direction is perpendicular to the line connecting the center of the fixed point at both ends.

When the W-shaped spring of the utility model is applied to the hinge of a flexible screen mobile terminal, it is always in a compressed state, occupies a small space, generates a large force value, and is in a short stroke. The force value fluctuates little, as shown in Figure 4, in this embodiment, its movement stroke (that is, the connection between the middle concave part 33 and the second part 2 is at the center point of the rotational connection between the two ends 31, 32 of the W-shaped spring and the movable part) The distance change between the connecting lines) is only 4.07 mm.

The second component 2 is a component slidably connected to the movable element, or a spring push plate. In this embodiment, the second part 2 is a spring push plate, one end 21 of the spring push plate is connected in rotation with the middle support structure 6 of the hinge, and the movable part 1 and the connecting part 7 are slidably connected. One end 71 is rotatably connected to the middle support structure 6 , and the axis of the connection piece 7 and the middle support structure 6 is rotatably connected to the axis of the spring push plate and the hinge middle support structure.

When the second part is a part that is slidably connected with the movable part, the second part (the second part can use the above-mentioned connecting part 7 at this time) is located between the movable part and the middle support structure of the hinge and the second part is rotatably connected with the middle support structure.

The movable member 1 can be installed on the support frame 4 and can be rotated relative to the support frame 4. The support frame 4 is a structure connecting the casing on one side of the mobile terminal in the hinge, and the support frame 4 is rotatably connected with the intermediate support structure 6. During the process of closing to opening, the support frame 4 and the movable part 1 rotate around the intermediate support structure 6, and the distance between the rotational connection points at both ends of the W-shaped spring relative to the intermediate support structure 6 will change (the distance change matches the mobile terminal when the flexible screen is bent to the flattened position). The distance that the mechanical structure needs to compensate, generally only a few millimeters) - the sequence of distance changes: far-near-far (the same is true for the process from opening to closing), and the W-shaped spring provides pressure throughout the process. Since the spring motion mechanism of the present invention can keep the spring force value large and the force value fluctuation small in a short stroke, the pressure can help solve the problem of maintaining the closed state of the flexible screen mobile terminal when it is in the closed state, and is helpful for It cooperates with the torque mechanism to obtain a better operating feel.

The above are only specific embodiments of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art in the field of the present utility model are all included in the present utility model. within the scope of new protection.
