[0033] Embodiment 1

[0034] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the utility model is: an umbrella surface, including a body 1, the body 1 has a plurality of hardness reinforcement areas 2, there is a gap between two adjacent hardness reinforcement areas 2, the hardness reinforcement areas 2 include a bottom glue layer 3, an intermediate layer 4 and a surface glue layer 5 which are stacked and connected in sequence, the bottom glue layer 3 is connected to the body 1, the material of the bottom glue layer 3 is PU glue, the thickness of the bottom glue layer 3 is 50-80 microns, the bottom glue layer 3 plays a bonding role, the thickness of the bottom glue layer 3 is 50-80 microns, which can ensure the lightness of the umbrella surface, and the modulus of the bottom glue layer 3 is less than or equal to 60MPa, so that the bottom glue Layer 3 forms a better bond with the body 1; the material of the middle layer 4 is PU glue, the thickness of the middle layer 4 is 100-120 microns, and the function of the middle layer 4 is to improve the modulus, hardness and rigidity of the hardness reinforcement area 2, so that the local area of ​​the umbrella surface has a larger structural hardness when a regular pattern is coated or printed, so that it is easy to fold neatly. The thickness of the middle layer 4 is 100-120 microns, which can take into account the thickness and hardness of the hardness reinforcement area 2, so that the thin and light umbrella surface is easier to fold. The modulus of the middle layer 4 is greater than or equal to 80MPa, so that the middle layer 4 can provide greater hardness and rigidity.

[0035] The material of the surface rubber layer 5 is PU rubber, and the modulus of the surface rubber layer 5 is greater than or equal to 80MPa. As a preferred embodiment, the surface rubber layer 5 is doped with a wear-resistant additive and / or a smoothing additive, thereby improving the wear resistance and / or smoothness of the hardness enhanced area 2, the wear-resistant additive includes but is not limited to a mixture of silicone oil and EVA, and the smoothing additive includes but is not limited to modified silicone resin. In a specific embodiment, the wear-resistant additive accounts for 0.5%-2% in the solution for subsequently forming the surface rubber layer 5, and the smoothing additive accounts for 0.05%-1% in the solution for subsequently forming the surface rubber layer 5.

[0036] The viscosity of the base adhesive layer 3 is greater than or equal to 9000 mPa.s, and the viscosity of the middle layer 4 is greater than or equal to 6000 mPa.s. The lower viscosity of the middle layer 4 allows for better bonding with the surface adhesive layer 5, while the higher viscosity of the base adhesive layer 3 allows for more adequate bonding between the base adhesive layer 3 and the body 1, thereby improving the bonding strength between the base adhesive layer 3 and the body 1.

[0037] Specifically, the plurality of hardness-enhanced areas 2 are arranged in at least one circle. When the umbrella surface is suitable for a multi-fold umbrella, the plurality of hardness-enhanced areas 2 are arranged in a plurality of concentric circles. At this time, the plurality of hardness-enhanced areas 2 are distributed radially.

[0038] The base adhesive layer 3 is formed by spraying and solidification, the middle layer 4 is formed by spraying and solidification, and the surface adhesive layer 5 is formed by spraying and solidification.

[0039] Preferably, the surface of the bottom adhesive layer 3 on one side close to the middle layer 4 is a first rough surface, which can improve the bonding strength between the bottom adhesive layer 3 and the middle layer 4 and reduce the risk of accidental separation between the bottom adhesive layer 3 and the middle layer 4; similarly, the surface of the middle layer 4 on one side close to the surface adhesive layer 5 is a second rough surface, which can improve the bonding strength between the surface adhesive layer 5 and the middle layer 4 and reduce the risk of accidental separation between the surface adhesive layer 5 and the middle layer 4. In detail, the first rough surface can be formed by grinding on the surface of the bottom adhesive layer 3 after the bottom adhesive layer 3 is cured; the second rough surface can be formed by grinding on the surface of the middle layer 4 after the middle layer 4 is cured.

[0040] To further improve the structural stability of the umbrella surface, optionally, the edge of the surface glue layer 5 extends outward to form an extension portion 6, and the extension portion 6 is generally in the shape of a ring frame, and the extension portion 6 connects the peripheral wall of the bottom glue layer 3, the peripheral wall of the middle layer 4 and the main body 1.

[0041] This embodiment also provides an umbrella, which includes an umbrella rib assembly, and the umbrella rib assembly is connected to the above-mentioned umbrella cover.

[0042] Embodiment 2

[0043] Please refer to Figure 3 , Embodiment 2 of the present utility model is a parallel technical solution of Embodiment 1, and is different from Embodiment 1 in that: all the hardness enhanced areas 2 in Embodiment 1 are in the form of sheets as a whole, while in this embodiment, at least part of the hardness enhanced areas 2 are in the form of ring frames as a whole, which is equivalent to hollowing out the central area on the basis of the hardness enhanced areas 2 in Embodiment 1. However, it should be noted that, in specific processing, there is no need to set a hollowing process, and when coating or printing the hardness enhanced areas 2, the ring frame structure can be directly coated or printed.

[0044] This embodiment also provides an umbrella, which includes an umbrella rib assembly, and the umbrella rib assembly is connected to the above-mentioned umbrella cover.

[0045] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
