Technical Field

[0001] The present invention relates to the field of consumer electronics, and particularly to an appearance part. Background Art

[0002] Currently, the consumer electronics industry is developing faster and faster, and each manufacturer is constantly seeking technological innovation and functional innovation to meet the development trends of environmental protection, energy conservation, and differentiation. The design of consumer electronic products has not been limited to the improvement of functions only. Many designers have turned their attention to the design of the appearance of consumer electronic products. Taking mobile phones as an example, the mobile phone cover plate not only plays a role in protecting the parts inside the mobile phone, but also plays a role in beautifying and decorating the mobile phone. An excellent design of the mobile phone cover plate can not only increase the value of the mobile phone, but also improve the user experience, expand the range of choices for the user in terms of the mobile phone's appearance, and make the mobile phone more popular among users.

[0003] However, currently, the decorative design of mobile phone cover plates focuses on the replacement of the cover plate substrate material (such as glass, metal, plastic) or the replacement of the single color of the printed ink layer on the cover plate substrate, resulting in a single visual effect, thus poor decorative effect and low recognition. Summary of the Invention

[0004] Based on this, it is necessary to provide an appearance part to solve the above technical problems.

[0005] One technical solution of the decorative sheet of the present invention is:

[0006] An appearance part, comprising:

[0010] The cross-section of the lenticular lens includes at least two hypotenuses, and the angles between the at least two hypotenuses and the flat surface are different.

[0011] In one embodiment, the cross-section of the lenticular lens is triangular, and the two hypotenuses are connected by an arc.

[0012] In one embodiment, the cross-section of the lenticular lens includes a base and three successively connected hypotenuses, and the angles between the three hypotenuses and the base are different.

[0014] In one embodiment, the thickness difference of the reflection layer in each part of the texture layer in the direction perpendicular to the flat surface is less than 5%.

[0015] In one embodiment, the reflection layer has different thicknesses corresponding to different hypotenuses of the lenticular lens; and the larger the angle between the hypotenuse and the flat surface, the smaller the corresponding thickness of the reflection layer.

[0016] In one embodiment, the cross-section of the lenticular lens includes two arc-shaped hypotenuses, and the two arc-shaped hypotenuses are smoothly connected.

[0017] In one embodiment, the hypotenuse is linear, outwardly convex arc-shaped or inwardly concave arc-shaped.

[0018] In one embodiment, the substrate layer is a PET layer, a PC layer, a PMMA layer, a PC composite layer, a thermosetting adhesive layer, a photocuring adhesive layer or a glass layer.

[0019] In one embodiment, the reflection layer is an evaporation coating, a sputtering coating, a chemical coating or an electroplating layer, or the reflection layer is a coating layer or a printing layer.

[0020] In one embodiment, it further includes a coloring layer and a transparent glass layer. The coloring layer is located on the side of the reflection layer away from the texture layer, and the transparent glass layer is located on the side of the substrate layer away from the texture layer. The substrate layer and the transparent glass layer are adhesively bonded.

[0030] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] The present invention discloses an appearance part, which includes a substrate layer, a texture layer and a reflective layer; the substrate layer includes a flat surface on one side; the texture layer is laminated with the substrate layer and is located on one side of the flat surface of the substrate layer, and the texture layer includes a plurality of lenticular lenses; the reflective layer is disposed on the side of the texture layer having the lenticular lenses, and the part of the texture layer in contact with the reflective layer is conformally arranged; the cross-section of the lenticular lens includes at least two hypotenuses, and the angles between at least two hypotenuses and the flat surface are different; the reflective layer presents different colors on each hypotenuse, so that different colors can be observed when observing the appearance part from different angles, and the appearance part has a high recognition rate. When used for decoration, it has a good decoration effect.

[0033] In one embodiment, the cross-section of the lenticular lens is triangular, and the two hypotenuses are connected by an arc. The color can transition naturally from one hypotenuse to the other.

[0034] In one embodiment, the cross-section of the lenticular lens includes a base and three successively connected hypotenuses, and the angles between the three hypotenuses and the base are different. That is, the lenticular lens has three inclined surfaces facing different directions, and the reflective layer on each inclined surface can present different colors.

[0035] In one embodiment, the reflective layer has different thicknesses corresponding to different hypotenuses of the lenticular lens, and different thicknesses can present different colors.

[0036] In one embodiment, the reflective layer has different materials at different oblique edges of the cylindrical mirror, and the reflective layers of different materials can present different colors.

[0037] In one embodiment, the reflective layer has different thicknesses and materials corresponding to different oblique edges of the cylindrical mirror, and can present different colors.

[0038] In one of the embodiments, the reflective layer has the same thickness at all locations on the texture layer in a direction perpendicular to the flat surface. Because of the angle of the hypotenuse, the actual thickness of the reflective layer in the direction perpendicular to the hypotenuse, i.e., in the cylindrical mirror, is smaller than the thickness in the vertical direction. The actual thickness of the hypotenuse at different angles is different, thereby displaying different colors.

[0039] In one embodiment, the reflective layer has different thicknesses at different oblique edges of the cylindrical mirror; and the larger the angle between the oblique edge and the flat surface, the smaller the corresponding thickness of the reflective layer.

[0040] In one embodiment, the cross section of the cylindrical mirror includes two arc-shaped beveled edges, and the two arc-shaped beveled edges are smoothly connected. The two arcs have no sharp angles, so that the color change is natural and not abrupt, and the visual effect is better.

[0041] In one embodiment, the hypotenuse is straight, convex or concave. The inclined surface where the hypotenuse of the cross section of the cylindrical mirror is located is not necessarily a flat surface, but can also be an arc convex outward or an arc concave inward. What's more, there are smaller-scale concavities and convexities on the inclined surface facing one direction, so that the displayed color has a frosted effect.

[0042] In one embodiment, the substrate layer is a PET layer, a PC layer, a PMMA layer, a PC composite layer, a heat-curing adhesive layer, a light-curing adhesive layer or a glass layer. For example, the substrate layer is a PET layer, and a UV adhesive is applied to the PET layer and then embossed and cured to form a texture layer, and a reflective layer is plated on the texture layer. The PET layer has its own OCA adhesive, and the appearance part is used to be attached to the glass, and can form, for example, a mobile phone back cover; for example, the substrate layer is a UV adhesive layer, and a cylindrical mirror is embossed on one side of the UV adhesive layer, and the substrate layer and the texture layer are an integrated structure; for example, the substrate layer is a glass layer, and a UV adhesive is applied to the glass layer and embossed and cured to form a texture layer, and then a reflective layer is plated on the texture layer; for example, the substrate layer is a laminated PET layer and a glass layer.

[0043] In one embodiment, the reflective layer is an evaporated coating, a sputtered coating, a chemically plated coating or an electroplated coating, or the reflective layer is a coated layer or a printed layer.

[0044] In one embodiment, the appearance part further includes a colored layer and a transparent glass layer, the colored layer is located on a side of the reflective layer away from the texture layer, the transparent glass layer is located on a side of the substrate layer away from the texture layer, and the substrate layer and the transparent glass layer are adhesively bonded.

[0045] Below, please refer to the figure to describe the appearance parts by example.

[0046] Please refer to Figure 1 , an appearance part, which includes a substrate layer 1, a texture layer 2 and a reflection layer 3; the substrate layer 1 includes a flat surface 11 located on one side; the texture layer 2 is stacked with the substrate layer 1 and is located on one side of the flat surface 11 of the substrate layer 1, and the texture layer 2 includes a plurality of cylindrical mirrors 21 with protrusions; the reflection layer 3 is covered on the side of the texture layer 2 having the cylindrical mirror 21, and the contact portion of the texture layer 2 and the reflection layer 3 is conformally arranged; the cross section of the cylindrical mirror 21 includes two oblique edges: a first oblique edge 211 and a second oblique edge 212, and the first oblique edge 211 and the second oblique edge 212 have different angles with the flat surface 11; the reflection layer 3 presents different colors on the first oblique edge 211 side and the second oblique edge 212 side of the cylindrical mirror 21, and different colors can be seen when observed from the first oblique edge 211 side and the second oblique edge 212 side, with high recognition, and has a good decorative effect when used for decoration of mobile phone back covers, etc.

[0047] For example, the reflective layer 3 is an evaporation coating, a sputtering coating, a chemical coating or an electroplating layer; or the reflective layer is a printing layer or a coating layer. When the reflective layer 3 is a coating, it is generally 5-8 layers. For example, the substrate layer 1 is a PET layer, a PC layer, a PMMA layer or a PC composite layer; or, the substrate layer 1 is a heat-curing adhesive layer or a light-curing adhesive layer, in which case the texture layer 2 and the substrate layer 1 can be made of the same material, that is, the texture layer 2 and the substrate layer 1 are integrally arranged, and the flat surface 11 is a virtual plane; or, the substrate layer 1 is a glass layer. For example, the texture layer 2 is a heat-curing adhesive or a light-curing adhesive, and the cylindrical mirror 21 is formed by embossing and curing; the texture layer 2 can also be made of other materials and the cylindrical mirror 21 is formed by laser etching.

[0048] Please refer to Figure 1 and Figure 2, the included angle α between the first hypotenuse 211 and the flat surface 11 is 21 degrees, and the included angle β between the second hypotenuse 212 and the flat surface 11 is 45 degrees; the inclination angles of the first hypotenuse 211 and the second hypotenuse 112 are different, and the orientations are different. The reflective layer 3 has substantially the same thickness h1 in the direction perpendicular to the flat surface at various positions of the texture layer 2. However, due to the different inclination angles, the perpendicular thickness h2 of the reflective layer 3 on the first hypotenuse 211 of the lenticular lens 21 is greater than the perpendicular thickness on the second hypotenuse 212, that is, h1≠h2. Therefore, the reflective layer 3 can present different colors on the first hypotenuse 211 side and the second hypotenuse 212 side of the lenticular lens 21. The appearance surface of the appearance part can be the side of the base layer 1 or the side of the reflective layer 3; when the appearance surface is the side of the base layer 1, the base layer 1 and the texture layer 2 are lens materials, and the reflective layer presents colors through the base layer 1 and the texture layer 2. The base layer 1 and / or the texture layer 2 can also be colored layers to assist in color display; the lenticular lens 21 can also have an optical effect to enhance the color display of the reflective layer 3.

[0049] In other embodiments, the reflective layer has different materials on the first hypotenuse side and the second hypotenuse side of the lenticular lens. For example, the material on the first hypotenuse side is SiO2, and the material on the second hypotenuse side is Ti3O5. Different materials can present different colors.

The cross-section of the lenticular lens 42 includes a first hypotenuse 4211 and a second hypotenuse 4212, and the included angles between the first hypotenuse 4211 and the second hypotenuse 4212 and the flat surface 411 are different; the reflective layer 43 presents different colors on the first hypotenuse 4211 side and the second hypotenuse 4212 side of the lenticular lens 421. Different colors can be seen when observing from the first hypotenuse 4211 side and the second hypotenuse 4212 side, with high recognition. When used for decoration such as a mobile phone back cover, it has a good decorative effect. The first hypotenuse 4211 and the second hypotenuse 4212 are connected by an arc 4213, so that the color change of the reflective layer 43 is natural and the display effect is good.
