Detailed Description

In one aspect of the present application, an electronic device housing is provided. With reference to fig. 1, it can be understood that the electronic device housing 10 includes: an appearance effect layer 400; a first transparent substrate layer 100, the first transparent substrate layer 100 being disposed on one surface of the appearance effect layer 400 (in the description of the present application, it is to be understood that the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. A first transparent leather effect layer 200, wherein the first transparent leather effect layer 200 is arranged on the surface of the first transparent substrate layer 100 far away from the appearance effect layer 400; and a second transparent leather effect layer 300, the second transparent leather effect layer 300 being disposed the first transparent leather effect layer 200 being far away from the first transparent substrate layer 100 on the surface thereof. The electronic device shell 10 can realize leather hand feeling and leather appearance effect by overlapping the first transparent leather effect layer 200 and the second transparent leather effect layer 300; in addition, since the first transparent leather effect layer 200 and the second transparent leather effect layer 300 are both transparent, other kinds of appearance effects can be realized through the appearance effect layer 400, and the structure is simple, the appearance effect is rich, and the expressive force is good.

It can be understood that the electronic device housing 10 described in this application may be specifically a metal middle frame of a mobile phone or a metal rear cover of a mobile phone, and certainly is not limited to the above category, and may also be other categories of electronic device housings in the related art, and redundant description is not repeated here.

It can be understood that the material of the first transparent substrate layer 100 may be selected to be a material that is convenient for carrying the first transparent leather effect layer 200, for example, in some examples of the present application, at least one of polyvinyl chloride (PVC), polyethylene terephthalate (PET), Polyimide (PI), Polycarbonate (PC) or Polyethylene (PE) may be selected as the specific material of the first transparent substrate layer 100, only one of the above materials may be adopted, or a laminated structure of the above materials may also be formed, and the materials of the first transparent substrate layer 100 may all be suitable for the electronic device housing 10 in the present application, and the application range is wide, and the commercial prospect is good. The thickness of the first transparent substrate layer 100 can be flexibly selected by those skilled in the art according to actual needs, and may be, for example, 0.05mm to 0.15mm, specifically, 0.05mm, 0.10mm, or 0.15 mm. In a specific example of the present application, the material of the first transparent substrate layer 100 is a PC film with a thickness of 0.125 mm.

In addition, it can be understood that, in the present application, since the electronic device housing 10 needs to simultaneously achieve leather feeling, leather appearance effect, and other kinds of appearance effect, the structure is simple, the appearance effect is rich, and the expressive force is good, when the transparency of the first transparent substrate layer 100 is also high, the formed appearance effect is good. In some embodiments of the present application, the light transmittance of the first transparent substrate layer 100 is greater than 85%, and specifically, may be 86%, 87%, 88%, 89%, or 90%, and the like, thereby forming a better appearance effect.

Further, it is understood that the thickness of the first transparent leather effect layer 200 may be 0.15mm to 0.4mm, and specifically, may be 0.15mm, 0.2mm, 0.3mm, or 0.4mm, etc.; the thickness of the second transparent leather effect layer 300 may be 0.03mm to 0.1mm, specifically, 0.03mm, 0.05mm, 0.07mm, or 0.1mm, etc., and then the total thickness of the first transparent leather effect layer 200 and the second transparent leather effect layer 300 may be 0.15mm to 0.80mm, and further, the total thickness of the first transparent leather effect layer 200 and the second transparent leather effect layer 300 may be 0.15mm to 0.60mm, specifically, 0.15mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, or 0.6mm, etc. Therefore, a better leather appearance effect is realized by regulating and controlling the total thickness of the first transparent leather effect layer 200 and the second transparent leather effect layer 300; when the total thickness of the first and second transparent

leather effect layers

200 and 300 is less than the aforementioned range, a leather hand feeling having sufficient softness cannot be embodied; when the total thickness of the first transparent leather effect layer 200 and the second transparent leather effect layer 300 is greater than the above range, the total thickness of the electronic device housing 10 is too thick, which is not suitable for the development of thinning electronic devices.

Still further, after a great deal of intensive investigation and experimental verification, the applicant finds that by adjusting the performance parameters of the second transparent leather effect layer 300, a better leather effect can be further achieved, specifically:

it is understood that the softness of the second transparent leather effect layer 300 may be 1.0mm to 7.0mm, and specifically, may be 1.0mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm, 7.0mm, or the like. The softness is determined by international standard ISO 17235: 2002(IULTCS/IUP 36), a better leather effect can be achieved when the softness of the second transparent leather effect layer 300 is within the above range, and when the softness is below the above range, the toughness is poor and the touch feeling is poor.

It is understood that the shore hardness of the second transparent leather effect layer 300 may be no greater than 30A, specifically, 25A, 26A, 27A, 28A, 29A, or 30A, etc., and the shore hardness of the second transparent leather effect layer 300 is suitable, which can provide high hardness and not cause poor leather feel due to its too hard hardness.

It is understood that the second transparent leather effect layer 300 may have a light transmittance of 40 to 88% with respect to light having a wavelength of 550nm, and specifically, the light transmittance may be 40%, 50%, 60%, 70%, 80%, 88%, or the like. Therefore, the second transparent leather effect layer 300 has a suitable light transmittance, which can further achieve a better leather effect, and when the light transmittance is lower than the above range, the appearance effect of the appearance effect layer 400 cannot be better reflected; when the light transmittance is higher than the above range, the transparency is too strong, and a better leather appearance effect cannot be realized.

It is understood that the haze of the second transparent leather effect layer 300 may be 5% to 60%, and specifically, the haze may be 5%, 10%, 20%, 30%, 40%, 50%, 60%, or the like. Therefore, the second transparent leather effect layer 300 has a proper haze, which can further achieve a better leather effect, and when the haze is lower than the above range, the transparency is too strong, which cannot show a better leather appearance effect; when the haze is higher than the above range, the light is scattered too strongly, and the appearance effect of the appearance effect layer 400 cannot be better exhibited.

In addition, it is understood that the materials forming the first and second transparent

leather effect layers

200 and 300 each independently include at least one of a polyurethane material, a polycarbonate material, and a polyvinyl chloride material, and by forming the first and second transparent

leather effect layers

200 and 300 using the above materials, the above softness, shore hardness, light transmittance, and haze can be better achieved. In a specific example of the present application, the material forming the first transparent leather effect layer 200 is a thermoplastic polyurethane elastomer (TPU), and the material forming the second transparent leather effect layer 300 is Polyurethane (PU). Therefore, the softness of the TPU is higher, and the surface of the TPU can realize better leather hand feeling and leather effect; the PU can provide the wear resistance of the electronic device housing 10 while achieving the leather feel, leather appearance, and other types of appearance, and has a wide and easily available material source and a low cost.

Still further, with reference to fig. 2, it can be understood that the appearance effect layer may specifically include: a first silk-screen pattern layer 410, wherein the first silk-screen pattern layer 410 is arranged on a part of the surface of the first transparent substrate layer 100 far away from the first transparent leather effect layer 200; a gradual color layer 420, wherein the gradual color layer 20 is disposed on the surface of the first silk-screen pattern layer 410 away from the first transparent substrate layer 100 and on the partial surface of the first transparent substrate layer 100 away from the first transparent leather effect layer 200; and a bottom-covering ink layer 430, wherein the bottom-covering ink layer 430 is disposed on the surface of the gradual color-changing layer 420 far away from the first silk-screen pattern layer 410 and the first transparent substrate layer 100. Therefore, the appearance effect of silk-screen patterns and the appearance effect of color gradual change can be further realized on the basis of realizing leather hand feeling and leather appearance effect.

Specifically, the specific silk-screen pattern of the first silk-screen pattern layer 410 may be flexibly selected by a person skilled in the art according to actual needs, and will not be described in detail herein; in addition, the material of the first silk-screen pattern layer 410 may include Polycarbonate (PC) or the like, and the thickness thereof may be 0.38mm to 0.64mm, and specifically, may be 0.38mm, 0.42mm, 0.56mm, or 0.64mm or the like. Therefore, the appearance effect of the silk-screen pattern can be better realized.

Specifically, the specific color of the gradient color layer 420 may be flexibly selected by those skilled in the art according to actual needs, and may be a gradient of two colors, or a gradient of a plurality of different colors, and the thickness thereof may be flexibly selected by those skilled in the art according to actual needs, for example, may be 15 μm to 30 μm, and specifically may be 15 μm, 20 μm, 25 μm, or 30 μm. Thereby, the appearance effect of the color gradation can be more effectively realized.

Specifically, the color of the under-cover ink layer 430 may be black or white, so that the electronic device having the electronic device housing 10 is not prone to internal light leakage, and a specific structure thereof is not particularly limited, and a person skilled in the art may flexibly select the under-cover ink layer according to actual needs, for example, in some specific examples of the present application, the under-cover ink layer 430 may be a stacked structure of multiple layers of ink, and a total thickness thereof may be 10 μm to 30 μm, specifically 10 μm, 20 μm, or 30 μm, and so on, and thus, redundant description is not repeated here.

Further, with reference to fig. 3, it can be understood that the appearance effect layer may further include: UV transfer texture layer 440 the UV transfer texture layer 440 is disposed between the gradient color layer 420 and the under-cover ink layer 430; and an optical coating layer 450, wherein the optical coating layer 450 is arranged between the UV transfer printing texture layer 440 and the bottom covering ink layer 430. Therefore, the texture effect and the electroplating reflection effect can be further realized on the basis of realizing the leather hand feeling, the leather appearance effect, the appearance effect of silk-screen patterns and the appearance effect of color gradual change.

Specifically, the specific texture pattern of the UV transfer texture layer 440 can be flexibly selected by those skilled in the art according to actual needs, for example, the specific texture pattern can be a nano-level fantasy pattern, and of course, other types of textures are also possible, which are not described in detail herein; in addition, the material of the UV transfer texture layer 440 may include UV glue, specifically urethane acrylate, and the like, and the thickness thereof may be 5 μm to 15 μm, specifically, 5 μm, 10 μm, or 15 μm, and the like. Thereby, the texture effect can be achieved better.

In particular, the optical coating layer 450 hasThe bulk material may include at least one of indium tin oxide, indium oxide, titanium oxide, niobium oxide, silicon oxide, and zirconium oxide, and specifically may be In-Sn, In, TiO₂、NbO₂、Nb₂O₃、Nb₂O₂、Nb₂O₅、SiO₂Or ZrO₂Etc.; the thickness may be 20nm to 500nm, specifically, 20nm, 50nm, 100nm, 120nm, 150nm, 180nm, 200nm, or the like. Therefore, different optical colors can be controlled and realized through the materials of the optical coating layers 400 with different refractive indexes and the proper thickness, so that the electroplating reflecting effect is better realized.

Further, with reference to fig. 4, it is understood that the electronic device housing 10 may further include: the second transparent substrate layer 500, the second transparent substrate layer 500 is arranged on the surface of the appearance effect layer close to the first transparent substrate layer 100; and a transparent adhesive layer 600, the transparent adhesive layer 600 is disposed between the second transparent substrate layer 500 and the first transparent substrate layer 100, and is used for bonding the second transparent substrate layer 500 and the first transparent substrate layer 100 together. Therefore, in the electronic device case 10 with such a structure, the leather effect can be formed on the surface of the first transparent substrate layer 100 and the appearance effect layer can be formed on the surface of the second transparent substrate layer 500 respectively in the manufacturing process, so that the yield of the whole process can be improved and the electronic device case is more easy to industrialize by manufacturing the leather effect layer and the appearance effect layer respectively; in addition, the appearance effect can be realized on the surfaces of the first transparent substrate layer 100 and the second transparent substrate layer 500 respectively, so that the overall appearance effect of the electronic device shell 10 can be further enhanced through superposition, and the expressive force is further improved.

More specifically, with reference to fig. 5 and 6, it can be understood that the electronic device housing 10 may further include a second silk-screen pattern layer 700, where the second silk-screen pattern layer 700 is disposed at least one of the following positions: a part of the surface of the first transparent substrate layer 100 close to the transparent bonding layer 600 (the structural schematic diagram refers to fig. 5); the second transparent substrate layer 500 is close to a part of the surface of the transparent adhesive layer 600 (the structural schematic diagram refers to fig. 6). Because there are second transparent substrate layer 500 and partial transparent tie coat 600 (fig. 5) at the interval between second silk screen pattern layer 700 and the gradual change color layer 420 or there is second transparent substrate layer 500 (fig. 6) at the interval between second silk screen pattern layer 700 and the gradual change color layer 420, consequently, the colour process of gradual change color layer 420 second transparent substrate layer 500 and transparent tie coat 600 or after the optical reflection in the second transparent substrate layer 500, gradual change color layer 420 with can produce comparatively obvious stereovision between the second silk screen pattern layer 700 to realize the visual effect of the suspension effect of colour or pattern or three-dimensional pane, thereby further make the visual effect of this electronic equipment casing 10 preferred, the expressive force further strengthens.
