Description

Technical Field

[0001] The present invention relates to the technical field of folding screens, and in particular to a novel sliding adhesive structure capable of significantly improving fold marks on folding screens. Background Art

[0002] When the folding screen changes from the unfolded state to the folded state, the screen will be deformed due to slippage, especially the last layer of M-Panel, which is generally made of SUS or carbon fiber material with a through-hole layer in the middle, and it is easy to have slight plastic deformation. Elastic deformation can be completely restored, but plastic deformation cannot be restored to its original state. That is to say, in the folded state, the M-Panel is slightly elongated due to the tensile effect. After the two ends of the folding screen M-Panel are fixed with sliding glue, the elongated part can only deform downward in the hinge area, resulting in very obvious creases. Summary of the invention

[0003] In view of the above-mentioned problems existing in the prior art, the main purpose of the present invention is to provide a new sliding glue structure that can significantly improve the crease of the folding screen.

[0004] The technical solution of the present invention is as follows: a new type of sliding rubber structure capable of significantly improving the folding mark of a folding screen, comprising a folding screen, a sliding rubber structure being arranged on the lower surface of the folding screen, and a middle frame being arranged below the sliding rubber structure;

[0005] The sliding glue structure is divided into a right sliding glue structure and a left sliding glue structure. The left sliding glue structure includes a uniform thickness part, the bottom surface of the uniform thickness part is the middle frame contact surface, and above the uniform thickness part is an inclined boss part, and the upper surface of the inclined boss part is the folding screen contact surface; the left sliding glue structure is the same as the left sliding glue structure, and the difference is that the inclination direction of the inclined boss part is opposite.

[0006] As a preferred embodiment, the folding screen is divided into a left folding screen and a right folding screen, the left folding screen is pasted with a left sliding adhesive structure on the bottom surface of the left folding screen, and the right sliding adhesive structure is pasted with a right sliding adhesive structure on the bottom surface of the right folding screen.

[0007] As a preferred implementation, the middle frame is divided into a right middle frame and a left middle frame, a right sliding adhesive structure is pasted on the top of the right middle frame, and a left sliding adhesive structure is pasted on the top of the left middle frame.

[0008] As a preferred implementation manner, the inclined boss portions are evenly distributed above the uniform thickness portion.

[0009] Compared with the prior art, the advantages and positive effects of the present invention lie in that, by designing the sliding glue into an inclined boss structure, when the sliding glue with the inclined boss structure is adhered together with the M-Panel and the middle frame, an internal stress is generated to push the folding screen to expand outward, so that the folding screen is straightened in the middle hinge area, greatly improving the crease effect of the folding screen.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example

[0018] A novel sliding adhesive structure capable of significantly improving the folding marks of a folding screen comprises a folding screen 1, a sliding adhesive structure 2 is arranged on the lower surface of the folding screen 1, and a middle frame 3 is arranged below the sliding adhesive structure 2;

[0019] The sliding adhesive structure 2 is divided into a right sliding adhesive structure 21 and a left sliding adhesive structure 22. The left sliding adhesive structure 22 includes a uniform thickness portion 222, the bottom surface of the uniform thickness portion 222 is a middle frame contact surface 221, and the upper surface of the uniform thickness portion 222 is an inclined boss portion 223, and the upper surface of the inclined boss portion 223 is a folding screen contact surface 224. The left sliding adhesive structure 22 is the same as the left sliding adhesive structure 22, and the difference is that the inclined boss portion 223 has an opposite inclination direction. The structure of the inclined boss portion 223 has strong restorability. After cold pressing, the sliding adhesive with multiple inclined bosses will deform downward and rightward. At the same time, due to its own strong restorability, it will inevitably generate internal stress to recover upward and leftward, thereby pushing the folding screen 1 pasted thereon to move leftward.

[0020] In actual process, there are three ways to realize the plurality of inclined boss portions 223 of the sliding rubber structure 2:

[0021] The first method: first apply a uniformly thick sliding adhesive to the entire surface, then use a deep concave pattern coating stick to extrude multiple inclined boss structures as shown in the figure, then clean off the excess parts that are squeezed out, and finally apply another layer to form a uniform sliding adhesive contact surface;

[0022] The second method: first apply the uniform thickness of the slip adhesive, then place the coated steel mesh with uniform gaps on the uniform thickness of the slip adhesive, and then continue to apply to the final thickness of the slip adhesive; finally remove the coated steel mesh, thereby forming the slip adhesive shape with multiple inclined boss structures as shown in the figure;

[0023] The third method: Use die-cutting to divide the slip adhesive into two parts, the upper and lower parts, which are first die-cut and then pasted together to form the slip adhesive shape with multiple inclined boss structures as shown in the figure.

[0024] The folding screen 1 is divided into a left folding screen 11 and a right folding screen 12. The left sliding adhesive structure 22 is pasted on the bottom surface of the left folding screen 11, and the right sliding adhesive structure 21 is pasted on the bottom surface of the right folding screen 12, so that the sliding adhesive structure 2 can evenly act on the left folding screen 11 and the right folding screen 12 to ensure uniform force.

[0025] The middle frame 3 is divided into a right middle frame 31 and a left middle frame 32. The right sliding adhesive structure 21 is pasted on the right middle frame 31, and the left sliding adhesive structure 22 is pasted on the left middle frame 32 to facilitate position fixing.

[0026] The inclined boss portions 223 are evenly distributed above the uniform thickness portion 222 , so that the forces applied by the inclined boss restoring elasticity of the inclined boss portions 223 are the same.

[0027] Working principle:

[0028] As shown in the figure, the left folding screen 11 and the right folding screen 12 of the folding screen 1 are respectively affixed with a right sliding glue structure 21 and a left sliding glue structure 22 with an inclined boss structure. After cold pressing, the sliding glue with an inclined boss structure in the right sliding glue structure 21 and the left sliding glue structure 22 will generate internal stress, which acts on the left folding screen 11 and the right folding screen 12 respectively to push them to extend outward, thereby flattening the crease and making the depth of the concave crease in the middle area quickly shallower, thereby greatly improving the crease of the folding screen.

[0029] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
