Abstract
Description
Technical Field
[0001] An eccentric axis control hovering design for hinges in torsional devices such as foldable screens relates to the field of electronic display devices. Background Technology
[0002] The hinges of existing electronic folding display devices are made up of dozens or even hundreds of tightly interlocked structural components such as multiple teeth, multiple wheels, and multiple springs. To achieve stability and hovering, the manufacturing process is complex and difficult, resulting in low yield, high cost, heavy weight, and thick thickness. The probability of failure is high, and the subsequent use and maintenance costs are relatively high.
[0003] Purpose of the invention
[0004] The purpose of this invention is to design a hinged hovering structure that uses frictional resistance generated by the slight eccentric torque between two axes to achieve hovering at any angle, and is lightweight, low-cost, and durable. Summary of the Invention
[0005] This invention comprises a single, continuous left wing 1 and several adjacent, staggered, separate right wings 2-1, 2-2, 2-3, 4, and 5-4, connected to various bushings located in the middle of the two wings. Specifically, the left wing bushing A1 (6) and the right wing bushing B1 (7) are adjacent and intersecting, coaxial and concentric, with the same shaft C1 (8) passing through them. The left wing bushing A1 (6) is laid flat on the left side of the left wing 1, and the right wing 2 (2-1) is on the right side of the right wing bushing B1 (7). The axis is D1 (9), forming one group. The axes of the first and second groups are not concentric, with slight deviations; specifically, the left wing bushing A2 (10) and the right wing bushing B2 (11) are adjacent and intersecting, coaxial and concentric, with the same shaft C2 (12) passing through them. A2 left wing bushing 10 is mounted horizontally on a section of the lower left side of left wing 1, and 2-2 right wing 3 is mounted on the right side of B2 right wing bushing 11. The axis is D2 axis 13. The bushings of the first and second groups are also offset from the axis, the purpose of which is to make the two axes compete with each other, and the torque on the left and right sides generates damping friction, so that the left and right wings restrain and balance each other, achieving the purpose of hovering at any time. There should be no less than two groups, two in a group, which is more beneficial, as it enhances balance, stability and damping effect. There is a third group, in which A3 left wing bushing 14 and B3 right wing bushing 15 are opposite and adjacent, coaxial and concentric, with C3 axis 16 passing through the middle. A3 left wing bushing 14 is mounted horizontally on a section of the left side of left wing 1, and 2-3 right wing 4 is mounted on the right side of B3 right wing bushing 15. The axis is D3 axis 17. There is a fourth group, consisting of A4 left wing bushing 18 and B4 right wing bushing 19, which are adjacent and intersecting, coaxial and concentric, with C4 shaft 20 passing through them. A4 left wing bushing 18 is laid flat on the left side of left wing 1, and right wing 4 is on the right side of B4 right wing bushing 19. The axis is D4 axis 21. Combined, they are spaced and intersecting in a pleasing manner. The first and third groups are coaxial, i.e., C1 axis 8 and C3 axis 16 are coaxial, i.e., D1 axis 9 and D3 axis 17 are the same. The second and fourth groups are coaxial, i.e., C2 axis 12 and C4 axis 20 are coaxial, i.e., D2 axis 13 and D4 axis 21 are the same.
[0006] The invention features a simple and stable structure, an uncomplicated manufacturing process, and controllable torsional damping. It is characterized by low cost, practicality, and durability. Attached Figure Description

[0009] Example 1: This example consists of a single, continuous left wing 1 and several adjacent, staggered right wings 2-1 (2-1), 2-2 (2-2), 2-3 (2-3), and 2-4 (2-4), connected to various bushings located in the middle of the two wings. Specifically, the left wing bushing A1 (6) and the right wing bushing B1 (7) are adjacent and intersecting, coaxial and concentric, with the same shaft C1 (8) passing through them. The left wing bushing A1 (6) is positioned horizontally on the left side of the left wing 1, and the right wing 2 (2-1) is positioned on the right side of the right wing bushing B1 (7). The axis is D1 (9), forming one group. The axes of the first group and the adjacent second group are not concentric, with slight deviations. Specifically, the left wing bushing A2 (10) and the right wing bushing B2 (11) are adjacent and intersecting, coaxial and concentric, with the same shaft C2 (12) passing through them. A2 left wing bushing 10 is mounted horizontally on the lower left side of the left wing 1. 2-2 right wing 3 is mounted on the right side of B2 right wing bushing 11. The axis is D2 axis 13. The bushings of the first and second groups are also offset from the axis, the purpose of which is to create an interlocking force between the two axes. The opposing torque generates damping friction, causing the left and right wings to restrain and balance each other, achieving the purpose of hovering at any time. The deviation range depends on the magnitude of the mutual torque between the two opposing axes, approximately 3-7% of the diameter of their respective axes, i.e., the distance between the axes of the two different axes, measured in micrometers. If it is too large, the eccentric torque of each axis exceeds the limit of free torsion, causing the left and right wings to jam. If it is too small, it will not provide effective damping friction. There should be at least two groups, paired together, which is beneficial for balance, stability, and damping effect. There is a third group, consisting of A3 left wing bushing 14 and B3 right wing bushing 15, which are adjacent and intersecting, coaxial and concentric, with C3 axis 16 passing through them. A3 left wing bushing 14 is mounted horizontally on the left side of left wing 1, and 2-3 right wing 4 is mounted on the right side of B3 right wing bushing 15. The axis is D3 axis 17. There is a fourth group, consisting of A4 left wing bushing 18 and B4 right wing bushing 19, which are adjacent and intersecting, coaxial and concentric, with C4 axis 20 passing through them. A4 left wing bushing 18 is mounted horizontally on the left side of left wing 1, and 2-4 right wing 4 is mounted on the right side of B4 right wing bushing 19. The axis is D4 axis 21. Combined, they are spaced and intersecting in a pleasing manner. The first and third groups are coaxial, that is, C1 axis 8 and C3 axis 16 are coaxial, that is, D1 axis 9 and D3 axis 17 are the same. The second and fourth groups are coaxial, meaning that axis C2 (12) and axis C4 (20) are coaxial, and axis D2 (13) and axis D4 (21) are the same. Thus, the eccentricity difference between the corresponding groups results in continuous damping, with equal forces counterbalancing each other, achieving the goal of stopping the left and right wings due to damping.
[0010] Example 2: This example differs from Example 1 in that, for two groups of shafts with adjacent starting positions, the two shafts with different deviations are transformed into a single, identical, through-axis. Similarly, for two groups of shafts with adjacent starting positions, the two shafts with different deviations are transformed into a single, identical, through-axis. In this example, the first and second groups are coaxial, i.e., shaft C1 (8) and shaft C2 (12) are coaxial, and shaft D1 and shaft D2 (13) are identical. The third and fourth groups are coaxial, i.e., shaft C3 (16) and shaft C4 (20) are coaxial, and shaft D3 (17) and shaft D4 (21) are identical. Thus, the eccentricity difference between the two shafts in each corresponding group (i.e., the first, second, third, and fourth groups) interacts, resulting in continuous damping and achieving the purpose of stopping friction suspension.
