In the shell assembly, the first texture layer and the second texture layer with different texture structures are arranged, wherein the texture layer with the pattern structure unit is beneficial to realizing a pattern logo effect on the shell assembly, and the texture layer with the lens structure unit can realize an effect of enlarging the pattern. So that the housing assembly in this embodiment can have a three-dimensional floating effect.

In an exemplary embodiment, as shown in fig. 1, the housing film layer structure of the present embodiment includes: a first transparent film layer 104, a first texture layer 102, and a second texture layer 103.

The first texture layer 102 is disposed on one surface of the first transparent film layer 104, and the second texture layer 103 is disposed on the other surface of the first transparent film layer 104. One of the first texture layer 102 and the second texture layer 103 is provided with a pattern structure unit, and the other layer is provided with a lens structure unit.

In this embodiment, the first texture layer 102 and the second texture layer 103 have different textures.

In one example, as shown in fig. 1, the pattern structure unit 20 is disposed on the first texture layer 102, and the lens structure unit 30 is disposed on the second texture layer 103. In this example, the lens structure unit 30 is disposed on the surface of the second texture layer 103 away from the first texture layer 102, and the lens structure unit 30 protrudes in a direction away from the pattern structure unit 20.

In another example, the pattern structure unit 20 is disposed on the second texture layer 103, and the lens structure unit 30 is disposed on the first texture layer 102. In this example, the pattern structure unit 20 is disposed on a surface of the second texture layer 103 close to the first texture layer 102, the lens structure unit 30 is disposed on a surface of the first texture layer 102 far from the second texture layer 103, and the lens structure unit 30 protrudes in a direction far from the pattern structure unit 20.

In this embodiment, the pattern structure unit 20 may be configured to have a desired logo pattern, such as a letter pattern, a number pattern, a cartoon pattern, and the like. The lens structure unit 30 is an optical microlens structure. The pattern structure unit 20 is used as an object, and the lens structure unit 30 magnifies and images the object to obtain a pattern with a three-dimensional and floating effect.

In this embodiment, a first transparent film layer 104 is disposed between the first texture layer 102 and the second texture layer 103.

In this embodiment, the first transparent film layer 104 may be an optical-grade transparent substrate, for example, a film material such as polyethylene terephthalate (PET), Polycarbonate (PC), or thermoplastic polyurethane elastomer (TPU) is selected.

Between the two texture layers, the first texture layer 102 and the second texture layer 103, lens imaging is involved. For example, when the first texture layer 102 is provided with the pattern structure unit 20 and the second texture layer 103 is provided with the lens structure unit 30, the lens structure unit 30 of the second texture layer 103 can image the pattern structure unit 20 of the first texture layer 102.

In this embodiment, the first transparent film layer 104 is disposed, so that the distance between the "object" and the "lens" can meet the imaging requirement without affecting the imaging relationship between the two texture layers.

In one exemplary embodiment, as shown in fig. 1, the pattern structure unit 20 includes: a groove body 201 with a preset pattern shape and a coloring layer 202, wherein the coloring layer 202 is arranged in the groove body 201 with the preset pattern shape.

In this embodiment, the coloring layer 202 can be set as an ink layer, and the color of the ink layer is selected according to the requirement. For example, when a black logo is required, the colored layer 202 may be a black ink layer. The colored layer 202 is matched with a groove body in a preset pattern shape, and a three-dimensional preset pattern with the same color as the colored layer 202 is visually felt.

In one example, the groove 201 of the preset pattern shape may be a plurality of groove 201 of letter shape, and a colored layer 202 of black is provided in the groove 201 corresponding to each letter, so that the pattern structure unit visually forms a logo pattern containing a plurality of letters with black. It can be understood that the slot 201 involved in the present embodiment may be a nm-scale micro slot. Correspondingly, the lens structure unit also needs to be arranged in a micro lens structure.

In an exemplary embodiment, as shown in fig. 1, a plurality of pattern structure units 20 are uniformly distributed in a predetermined region of the texture layer.

In the embodiment, the pattern structure unit 20 is disposed on the first texture layer 102, and the predetermined area may be a local area of the first texture layer 102. A plurality of pattern structure units 20 are disposed in a local region of the first texture layer 102. For example, the pattern structure unit 20 is provided as a letter pattern "RED".

In an exemplary embodiment, as shown in fig. 1, a plurality of lens structure units 30 are uniformly distributed on the texture layer according to a predetermined shape.

In this embodiment, the lens structure unit 30 is disposed on the second texture layer 103. For example, the plurality of lens structure units 30 are uniformly distributed over the entire texture layer. For the predetermined area, the pattern structure units 20 in the predetermined area of the first texture layer 102 correspond to the partial lens structure units 30 of the second texture layer 103 in a one-to-one manner.

The distribution area of the lens structure units 30 may be larger than the distribution area of the pattern structure units 20, so as to further ensure the three-dimensional suspension effect. For example, the area of the distribution of the lens structure units 30 on the second texture layer 103 can cover the area of the distribution of the pattern structure units 20 on the first texture layer 102. So that the lens structure unit 30 can magnify and image all the pattern elements in the pattern structure unit 20 to ensure the effect of three-dimensional suspension.

In one example, as shown in FIG. 2, a plurality of lenticular structure cells 30 are arranged in a matrix array, with rows and columns of lenticular structure cells 30 aligned.

In another example, as shown in FIG. 3, the plurality of lens structure cells 30 are arranged in a honeycomb pattern, with lens structure cells 30 in different columns or different rows not being perfectly aligned.

In this embodiment, the lens structure units 30 are regularly and tightly arranged, which is beneficial to amplifying and imaging the pattern corresponding to the pattern structure unit 20 in all directions, so as to avoid the partial edge structure of the pattern being missing.

In this embodiment, on the basis that the plurality of pattern structure units 20 are uniformly distributed in the preset area of the texture layer, and in combination with the different positions of the lens structure units 30 and the pattern structure units 20, the imaging of the lens structure units 30 may be different, the lens structure unit 20 illustrated in fig. 2 may be a portion located right above the pattern structure unit 20, which may image more pattern portions, and the image in each lens structure unit 30 may have a slight difference.

It will be appreciated that when the lens structure unit 20 is located at the edge, a small portion of the pattern, for example "R", may be imaged.

Based on the pattern structure units 20 in the form of the plurality of letter patterns "RED" and the plurality of lens structure units 20, the shell film structure in this embodiment can image a larger logo suspended image "RED".

In an exemplary embodiment, as shown in fig. 1 to 3, the aperture of the lens structure unit 30 is 30 μm to 200 μm. For example, the aperture may be set to 120 μm.

In this embodiment, the distance between the center points of two adjacent lens structure units 30 is 35 μm to 205 μm. For example, the pitch of the center points is set to 125 μm, i.e., the period in which the lens structure units 30 are arranged is set to 125 μm.

The aperture and the period of the lens structure unit 30 can be adjusted within the corresponding range. When the aperture of the lens structure unit 30 is selected to be small, the period for disposing the lens structure unit 30 should be also reduced to ensure the compactness of disposing the lens structure unit 30.

In one exemplary embodiment, as shown in fig. 1 to 3, the distance between the preset reference points of two adjacent pattern structure units 20 is the same as the distance between the center points of two adjacent lens structure units 30.

In this embodiment, the distance between the predetermined reference points of two adjacent pattern structure units 20 is the period of the two adjacent pattern structure units 20. The period in which two adjacent pattern structure units 20 are arranged is the same as the period in which two adjacent lens structure units 30 are arranged, for example, 125 μm.

In one example, the pattern structure unit 20 is provided as a letter pattern "RED", and the selection of the preset reference point is not limited, but the preset reference points of the two pattern structure units 20 should be the same. For example, if the predetermined reference point of the pattern structure unit 20 is selected as "r", the pitch of the predetermined reference points "r" of two adjacent pattern structure units 20 may be set to 125 μm. In this example, the pitch between the center points of two adjacent lens structure units 30 is also set to 125 μm.

In an exemplary embodiment, as shown in FIGS. 1 to 3, the magnification of the lens structure unit 30 is 1 to 300 times. The amplification factor can be adjusted according to the requirement, and can be set to 150 times in this embodiment.

In the present embodiment, the distance between the pattern structure unit 20 of the first texture layer 102 and the lens structure unit 30 corresponding to the second texture layer 103 may be set to 73 μm. This distance can be adjusted according to the magnification of the lens structure unit 30.

In the embodiment of the disclosure, based on the structural arrangement on the first texture layer 102 and the second texture layer 103, a large logo image with a floating height of 7mm can be formed for a plurality of pattern structure units 20. The image floating effect and the image floating height can be adjusted and optimized by adjusting the setting period of the pattern structure unit 20, the setting period of the lens structure unit 30, the thickness of the first transparent film layer 104, the refractive index, and other factors.

In one exemplary embodiment, as shown in FIG. 1, the first texture layer 102 or the second texture layer 103 has a thickness of 0.008mm to 0.05 mm.

In this embodiment, the first texture layer 102 and the second texture layer 103 may be UV texture layers, and the textures are formed by laser engraving mold transfer. For example, a desired pattern, such as the pattern structure unit 20 or the lens structure unit 30, is first formed on a substrate by a laser engraving mold. Then, a UV glue (ultraviolet curing glue) is coated on the substrate with the processed pattern, and is irradiated by ultraviolet rays, and after the UV glue is cured and molded, the first texture layer 102 or the second texture layer is obtained.
