It should be noted that, in the description manner used herein, the "millimeter-scale first stereoscopic texture" and the "millimeter-scale second stereoscopic texture" mean that at least one dimension of the first stereoscopic texture and the second stereoscopic texture is millimeter-scale, that is, the dimension in at least one dimension may be 0.1mm to 10mm, for example, the height of the stereoscopic texture or the line width of the stereoscopic texture may be millimeter-scale, or both the height of the stereoscopic texture and the line width of the stereoscopic texture may be millimeter-scale.
It is to be understood that the specific material of the housing body is not particularly limited, and may be any material that can be applied to the housing of the electronic device. Specifically, the shell body can be made of glass, ceramic and the like, so that the material source is wide, the price is low, the signal shielding problem is avoided, and the use requirement of 5G can be met. In some embodiments, the housing body is made of glass. Therefore, the material has wide sources, good optical performance and lower cost.
It is understood that the first stereoscopic texture and the second stereoscopic texture may each independently include a plurality of texture surfaces, at least a portion of the texture surfaces intersect, and an R angle at the intersection of two texture surfaces is equal to or greater than 0.2mm, specifically, may be 0.5mm to 3mm, and more specifically, may be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.3mm, 1.8mm, 2.0mm, 2.2mm, 2.5mm, 2.8mm, 3.0mm, and the like. From this, first three-dimensional texture and second three-dimensional texture have obvious edges and corners structure, and the outward appearance effect is more three-dimensional, and visual impact sense is stronger, and more fashion, individual character can bring better use experience for the user.
It should be noted that the description manner "R angle" herein refers to the radius of the transition circular arc at the intersection of two texture surfaces, and the specific schematic diagram refers to fig. 3; in addition, "independent" means that they do not affect each other, for example, the first stereo texture and the second stereo texture may independently satisfy a certain parameter range, which means that the specific values of the parameter of the first stereo texture and the second stereo texture do not affect each other, that is, the specific value of the parameter of the first stereo texture and the specific value of the parameter of the second stereo texture may be the same or different.
It is understood that, referring to fig. 1, 2 and 4, the first three-dimensional texture 22 and the second three-dimensional texture 24 may be convex toward the outside of the housing body 10, or concave toward the inside of the housing body 10, and may be selected according to the appearance effect to be achieved. In some embodiments, referring to fig. 1 and 2, the first three-dimensional texture 22 is recessed toward the inside of the housing body 10, and the second three-dimensional texture 24 is raised toward the outside of the housing body 10. From this, the internal surface of casing body is easily assembled with other subassemblies of electronic equipment more, space utilization has been improved, do benefit to the miniaturization that realizes electronic equipment, can avoid simultaneously causing in the assembling process to the stereoscopic texture colliding with, damage such as scraping, the finished product yield is higher, the outward appearance effect is better, the outside arch of second stereoscopic texture of surface, the user can directly experience the stereoscopic effect during the touch, this casing realizes strong third dimension simultaneously in vision and sense of touch, give the user with fresher, the stronger use experience of impact sensation, satisfy fashion and individualized requirement.
Specifically, the specific shape and size of the first stereoscopic texture and the second stereoscopic texture are not particularly limited, and can be flexibly selected according to actual needs. In some embodiments, referring to fig. 5 and 6, the first and second stereoscopic textures each independently include at least one of a straight stripe, a curved stripe, a geometric figure, and an irregular figure. Therefore, richer and more attractive appearance effects can be realized, and the user experience is improved.
Specifically, the cross-sectional shape of each first stereo texture and each second stereo texture may be various, and in some embodiments, the cross-sectional shape of each first stereo texture and each second stereo texture may be a triangle (see fig. 1, 2 and 4), a trapezoid (see fig. 7), a rectangle (see fig. 8), a circle (see fig. 9), and other planar geometric shapes and irregular shapes (see fig. 10), which are independent of each other. Thereby, a more abundant and various three-dimensional appearance can be provided. It should be noted that the circle segment refers to one of two portions formed by linearly cutting a circle, that is, two portions formed by linearly cutting a circle, where each portion may be referred to as a circle segment.
Specifically, the specific size of the first three-dimensional texture and the second three-dimensional texture in the electronic device shell is millimeter (0.1 mm-10 mm), strong three-dimensional effect can be visually seen by naked eyes in the size range, the difference with the visible light wavelength is obvious, optical effects such as interference and diffraction are basically not generated, and a user can directly feel strong three-dimensional visual impact. Specifically, the height of the first stereoscopic texture may be less than or equal to the height of the second stereoscopic texture. Specifically, the first three-dimensional texture on the inner surface is mainly used for observing the three-dimensional effect by naked eyes, the smaller texture height can be effectively recognized by the naked eyes, the processing is easy, the assembly of other parts in the electronic equipment is facilitated, the thickness of the shell body is reduced, the shell is lighter and thinner, the second three-dimensional texture on the outer surface is used for giving three-dimensional visual impact to a user and directly sensing the three-dimensional appearance effect when the user holds the electronic equipment, and the height of the second three-dimensional texture is relatively larger in order to ensure more obvious three-dimensional touch.
In some specific embodiments, the height H1 of the first three-dimensional texture can be 0.1-1 mm (specifically, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, etc.); the height H2 of the second three-dimensional texture may be 0.5 to 2.5mm, specifically 0.5 to 2mm, more specifically 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, and the like.
It should be noted that the description manner "the height of the three-dimensional texture" used herein refers to a depth of the three-dimensional texture recessed into the housing body or a height of the three-dimensional texture protruding to the outside of the housing body, specifically, taking the example that the three-dimensional texture is provided on the inner surface of the bottom wall, when the three-dimensional texture is recessed into the housing body, a portion other than the recessed three-dimensional texture forms a protruding portion, the inner surface of the protruding portion is located in a plane or an arc (see the dotted line in fig. 1, 2, and 4), and the height of the three-dimensional texture refers to a depth of the three-dimensional texture recessed into the housing body relative to the plane or the arc. Similarly, when the three-dimensional texture protrudes to the outside of the shell body, the part outside the protruding three-dimensional texture forms a concave part, the concave part is positioned in a plane or an arc surface, and the height of the three-dimensional texture refers to the height of the three-dimensional texture protruding to the outside of the shell body relative to the plane or the arc surface.
In some specific embodiments, the line width W1 of the first stereoscopic texture and the line width W2 of the second stereoscopic texture may be respectively and independently greater than or equal to 1mm, specifically may be 1 to 10mm, and more specifically may be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, and the like. It should be noted that the first stereo texture and the second stereo texture may each independently include a plurality of stripe lines, and the width of each stripe line is within the above range, but the widths may be the same or different. Within this range, the stereoscopic effect is stronger, and the appearance effect is better, and easily processes, if the undersize, the processing degree of difficulty increases, and the texture may collapse, damage, if too big can be unfavorable for realizing more diversified appearance effect.
It is to be understood that the first stereo texture and the second stereo texture may be each independently a continuous texture (see fig. 6) or may be a plurality of textures arranged at intervals (see fig. 7). In some specific embodiments, the first three-dimensional texture and the second three-dimensional texture may each independently include a plurality of sub-textures arranged at intervals, and a distance L between two adjacent sub-textures is greater than or equal to 1mm, specifically may be 1 to 15mm, and more specifically may be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, and the like. Therefore, the texture space can be flexibly set as required, and rich and diversified appearance effects are realized.
In some embodiments, referring to fig. 2, the maximum thickness D1 of the housing body 10 may be 3-10 mm (specifically, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.), and the minimum thickness D2 of the housing body 10 may be 0.4mm (specifically, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc.) or more. Therefore, the three-dimensional texture is realized, the strength requirement of the electronic equipment shell in use can be ensured, and the development trend of light weight and thinness is met.
It should be noted that, since the inner surface and the outer surface of at least one of the bottom wall and the side wall have three-dimensional textures, that is, the inner surface and the outer surface are both non-flat, the thicknesses of different positions of the housing body may be different (non-uniform), the maximum thickness of the housing body refers to the thickness at the position where the thickness of the housing body is maximum, and the minimum thickness of the housing body refers to the thickness at the position where the thickness of the housing body is minimum. In other embodiments, the thicknesses of the different positions of the housing body may be substantially the same (equal thickness), and referring to fig. 11, that is, the three-dimensional texture of the inner surface of the housing body and the three-dimensional texture of the outer surface of the housing body are mutually matched, and the three-dimensional texture of the inner surface is convex toward the outside of the housing body, so that the three-dimensional texture of the outer surface at the corresponding position is concave toward the inside of the housing body, whereas the three-dimensional texture of the inner surface is concave toward the inside of the housing body, so that the three-dimensional texture of the outer surface at the corresponding position is convex toward the.
In addition, orthographic projections of the first three-dimensional texture and the second three-dimensional texture in the thickness direction of the shell body can be at least partially not overlapped, so that the first three-dimensional texture and the second three-dimensional texture can be directly seen by a user, and the appearance of the shell can be enriched. In some embodiments, orthographic projections of the first stereoscopic texture and the second stereoscopic texture in the thickness direction of the shell body may not overlap at all, or may not overlap at a part of the overlapping portion. Furthermore, the first three-dimensional texture and the second three-dimensional texture can be superposed together to form a finished decorative pattern, for example, the first three-dimensional texture can form a pattern of stars, the second first texture can form a pattern of stars, such as moon, sun, and the like, and the first three-dimensional texture and the second three-dimensional texture can be superposed to form a decorative pattern of sky and the like.
It is understood that, referring to fig. 12, the electronic device case may further include: a decorative membrane 30, said decorative membrane 30 being disposed on the inner surface of said bottom wall 12 and said side wall 14. Therefore, the appearance decoration effects of different colors, different patterns and the like can be realized through the decoration membrane, so that the appearance of the shell is richer and more various and more gorgeous, and the aesthetic requirement of a user is better met.
It can be understood that the decorative film may be a multilayer structure, and specifically may include a color layer, a texture layer, a bottom-covering ink layer, a necessary adhesive layer, and the like, and may also include a substrate film, where the color layer, the texture layer, the bottom-covering ink layer, and the like are formed on the substrate film in advance, and then are attached to the inner surface of the housing. The specific decorative film structure, material, etc. can be selected with more actually required appearance effects, and are not described in detail herein.
In another aspect of the present application, a method of making an electronic device housing is provided. According to an embodiment of the application, the method comprises: providing a substrate, wherein the plate has an inner surface and an outer surface which are oppositely arranged; performing a first CNC process on the substrate, the first CNC process comprising: removing a portion of the substrate from the inner surface side such that the substrate forms a bottom wall and at least one side wall connected to the bottom wall and forms a millimeter-scale three-dimensional texture on at least one of the inner surface of the bottom wall and the inner surface of the side wall; performing a second CNC process on the substrate subjected to the first CNC process, the second CNC process including: processing the outer surface of the base material at the position corresponding to the side wall into an arc surface; removing a portion of the substrate on the outer surface side to form a second three-dimensional texture on the millimeter scale on at least one of the outer surface of the bottom wall and the outer surface of the side wall. The method is carried out by adopting CNC machining, the operation steps are simple, the implementation is easy, the automation degree and the machining precision are high, the CNC machining technology is mature, and the industrial production is easy to realize.
It can be understood that, in the second CNC machining process, there is no sequential limitation in the step of removing a portion of the base material from one side of the outer surface to form the second three-dimensional texture and the step of machining the outer surface of the base material at the position corresponding to the side wall into the arc surface, a portion of the base material may be removed first to form the second three-dimensional texture, and then the outer surface corresponding to the side wall is machined into the arc surface, or the outer surface corresponding to the side wall may be machined into the arc surface first, and then a portion of the base material is removed to form the second three-dimensional texture, and particularly, the method may be flexibly adjusted as required.
It is understood that the above method may further include: and processing the outer surface of the base material at the position corresponding to the bottom wall into an arc surface. Thereby, a housing having a 3D structure can be formed. Specifically, this step may be performed before the second stereoscopic texture is formed, or may be performed simultaneously with the formation of the second stereoscopic texture.
Specifically, before the second CNC machining, the substrate subjected to the first CNC machining is fixed on a jig, and a surface of the jig, which is in contact with the substrate, has a profiling three-dimensional texture complementary to the first three-dimensional texture, so that the first three-dimensional texture can be fixed in the profiling three-dimensional texture in a matching manner. Therefore, the base material with the first three-dimensional texture can be better fixed, the profiling three-dimensional texture can be well matched with the first three-dimensional texture, and the first three-dimensional texture cannot be damaged.
It should be noted that, the description "the copying three-dimensional texture complementary to the first three-dimensional texture" used herein refers to that the copying three-dimensional texture is complementary to the first three-dimensional texture, and specifically refers to that the sizes and the protruding and recessed tendencies of the first three-dimensional texture and the copying texture are about the same at the corresponding positions of the substrate and the jig (i.e., the position where the jig is fixed on the substrate and the substrate needs to be contacted), when the substrate is fixed on the jig, the three-dimensional texture can be exactly placed in the copying texture, and there is almost no gap between the two at the contact position.
Specifically, the specific steps and parameters of the CNC processing can be flexibly adjusted according to the structures and patterns to be realized, and are not described in detail herein. While those skilled in the art will appreciate that the method may be used to prepare an electronic device housing as described above, the features and advantages involved may be consistent with the corresponding description above and will not be described one by one.
In one embodiment, a flat substrate may be provided, a first three-dimensional texture may be formed on an inner surface of the substrate by CNC processing, the obtained substrate may be fixed and adsorbed on a jig (specifically, a 3D base having the profiling texture in the jig) having the profiling three-dimensional texture, an outer surface corresponding to the sidewall may be further processed into an arc surface by CNC processing, and a second three-dimensional texture may be formed on an outer surface corresponding to the bottom wall.
It can be understood that, when the shell body is of the same thickness, the shell body can also be made by molding the substrate with a mold, specifically, the substrate can be molded by using a mold with a target texture shape under certain temperature and pressure conditions, so that the edge of the substrate is bent to form the side wall of the shell body while the inner surface and the outer surface of the substrate form the three-dimensional texture.
In another aspect of the present application, an electronic device is provided. According to an embodiment of the present application, referring to fig. 13, the electronic device includes the electronic device case 100 described above, and the side wall and the bottom wall of the electronic device case together define a receiving space; a display screen 200, the display screen 200 being disposed in the accommodating space.
