Description

Technical Field

[0001] This utility model relates to the field of hinge device technology, specifically to an ultra-thin flexible folding screen folding hinge device. Background Technology

[0002] Ultra-thin flexible foldable screens are an advanced display technology that combines the characteristics of being ultra-thin, flexible, and foldable. By using advanced materials and manufacturing processes, the screen is made ultra-thin and can be bent and folded. It can be unfolded into a larger display area when needed and folded up when not needed, thereby increasing the flexibility and portability of the device.

[0003] As technology matures and costs decrease, the market size of ultra-thin flexible foldable screen devices is expanding. As a key component that connects and supports flexible screens, the performance of the hinge directly affects the user experience and lifespan of the flexible screen terminal. Although ultra-thin flexible screens have good flexibility, if the hinge does not have a protective structure during folding, pressure can easily be concentrated at the folding point, leading to screen damage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-4 The present invention provides an embodiment of an ultra-thin flexible folding screen hinge device, comprising: a hinge device body 1, and further comprising...

[0023] The lower folding piece 5 is disposed on both sides inside the hinge device body 1 via the second roller 18, and the top of the lower folding piece 5 is provided with the upper folding piece 4.

[0024] The ultra-thin flexible screen body 8 is disposed between the upper folding component 4 and the lower folding component 5.

[0025] The hinge device body 1 has a first fixing part 2 and a second fixing part 3 respectively on both sides above it, and the first fixing part 2 and the second fixing part 3 are respectively connected to the upper folding parts 4 on both sides of the ultra-thin flexible screen body 8.

[0026] The first fixing part 2 and the second fixing part 3 are respectively connected to the shells on both sides of the mobile phone screen, and the ultra-thin flexible screen body 8 is disposed between the upper folding part 4 and the lower folding part 5.

[0027] Two sets of first rollers 16 are provided at the bottom of the interior of the hinge device body 1, and toothed sleeves 17 are provided on the outer side of each first roller 16.

[0028] The lower folding piece 5 is provided with teeth 15 at the end near the toothed sleeve 17, and the teeth 15 respectively engage with the toothed sleeve 17;

[0029] By pulling the first fixing part 2 and the second fixing part 3 outward, the upper folding part 4 and the lower folding part 5 are rotated outward, thereby unfolding the ultra-thin flexible screen body 8.

[0030] Since the teeth 15 on the lower folding piece 5 mesh with the toothed sleeve 17 on the outside of the first roller 16, the meshing action can keep it stable when folded to a specific angle, and there will be no shaking or loosening. At the same time, it ensures that the ultra-thin flexible screen body 8 remains neat during the folding process, and avoids misalignment or unevenness.

[0031] The bottom of the upper folding part 4 is rotatably connected to the top of the lower folding part 5 through the damping pivot 6. Both the upper folding part 4 and the lower folding part 5 are made of liquid metal, which has the advantages of high strength and lightweight, ensuring the durability and stability of the hinge device body 1.

[0032] The upper folding piece 4 and the lower folding piece 5 are respectively provided with a first pressure-resistant groove 9 and a second pressure-resistant groove 7 on the side near the ultra-thin flexible screen body 8.

[0033] The pressure-resistant components 10 are evenly distributed inside the first pressure-resistant groove 9 and the second pressure-resistant groove 7, and the end of each pressure-resistant component 10 near the ultra-thin flexible screen body 8 is connected to the ultra-thin flexible screen body 8 through the connecting part 11. The pressure-resistant components 10 are all made of silicone material.

[0034] When the ultra-thin flexible screen body 8 is folded or unfolded, the upper folding piece 4 and the lower folding piece 5 will generate a certain amount of friction and impact between them and the ultra-thin flexible screen body 8. The pressure-resistant piece 10 can fill the gap and absorb the impact, reducing the direct pressure of the hinge device body 1 on the ultra-thin flexible screen body 8.

[0035] Each compression member 10 has a sleeve 12 at the center of its interior, and each sleeve 12 has a reinforcing rib 13 embedded inside to improve the structural strength of the compression member 10.

[0036] The pressure-relieving chambers 14 are provided around the inside of the pressure-resistant component 10, and the pressure-relieving chambers 14 are distributed in a concentric circle structure around the pressure-resistant component 10. This can reduce the weight of the pressure-resistant component 10, and reduce the amount of material used while maintaining strength and performance, thereby achieving the purpose of lightweighting.

[0037] Working principle: In this embodiment, the first fixing part 2 and the second fixing part 3 are respectively connected to the shells on both sides of the mobile phone screen. The ultra-thin flexible screen body 8 is disposed between the upper folding part 4 and the lower folding part 5. By pulling the first fixing part 2 and the second fixing part 3 outward, the upper folding part 4 and the lower folding part 5 are rotated outward, thereby unfolding the ultra-thin flexible screen body 8. Since the teeth 15 on the lower folding part 5 engage with the toothed sleeve 17 on the outside of the first roller 16, the engagement can keep it stable when folded to a specific angle, without shaking or loosening. At the same time, it ensures that the ultra-thin flexible screen body 8 remains neat during the folding process, avoiding misalignment or unevenness. Meanwhile, the upper folding part 4 and the lower folding part 5 are close to the ultra-thin flexible screen body 8. The first pressure-resistant groove 9 and the second pressure-resistant groove 7 are respectively provided on the sides. The interior of the first pressure-resistant groove 9 and the second pressure-resistant groove 7 are evenly connected to both sides of the ultra-thin flexible screen body 8 through the pressure-resistant component 10. The pressure-resistant component 10 is made of silicone material and has good buffering and shock absorption performance. When the ultra-thin flexible screen body 8 is folded or unfolded, a certain friction and impact force will be generated between the upper folding component 4 and the lower folding component 5 and the ultra-thin flexible screen body 8. The pressure-resistant component 10 can fill the gap and absorb the impact force, reducing the direct pressure of the hinge device body 1 on the ultra-thin flexible screen body 8. The pressure-relieving cavity 14 is evenly provided around the inside of the pressure-resistant component 10, which can reduce the weight of the pressure-resistant component 10. While maintaining strength and performance, the amount of material used is reduced, thereby achieving the purpose of lightweighting.
