Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic products, and particularly relates to a housing structure and an electronic product. Background Art
[0002] With the popularization and diversification of electronic products, consumers' requirements for the appearance of products are getting higher and higher. The housings of current electronic products on the market usually adopt a single texture, and the single texture results in a single color. Although this design is simple, it has certain limitations in terms of personalization and aesthetics.
[0003] In the related art, in order to meet consumers' demands for the diversification of the appearance of electronic products, the method of splicing multiple housings is often used to achieve the effect of two-color or multi-color textures. However, the splicing process is relatively complex and requires precise alignment of components with different colors or textures, which not only increases the production cost but also prolongs the production cycle; moreover, the spliced housings may have defects in terms of structural strength and durability due to the existence of splicing points.

[0018] The present utility model provides a housing structure 100.
[0019] Please refer to Figure 1 , in an embodiment of the present utility model, the housing structure 100 includes a base material layer 1 and a sand oxidation layer; the base material layer 1 is an integrally formed structure; the sand oxidation layer includes at least two sand oxidation sections 2 with different surface roughnesses, and each sand oxidation section 2 is respectively arranged at different parts of the surface of the base material layer 1.
[0020] The base material layer 1 is colored through anodization. Therefore, the material of the base material layer 1 needs to meet the corresponding requirements. In this embodiment, the material of the base material layer 1 is aluminum. After anodization, aluminum materials can form various colors, such as gray, black, brown, etc., and can also be electrolytically colored to form champagne, bronze, blue, green, etc. In other embodiments, the material of the base material layer 1 can be aluminum alloy or titanium alloy. Among them, due to the difference in composition of different grades of aluminum alloy, different colors will be presented after anodization.
[0021] Each sand oxidation section 2 is an oxide layer formed by anodization after sandblasting on the surface of the base material layer 1. Taking an aluminum shell as an example, sandblasting can change the surface of the aluminum shell from high gloss to matte or rough texture; sands of different thicknesses can produce different texture effects, increasing the three-dimensional sense of the surface of the aluminum shell. At the same time, sands of different thicknesses will result in different surface roughnesses of the sand oxidation section 2 formed by anodizing the surface of the aluminum shell. The sand oxidation section 2 with different surface roughnesses will affect the scattering mode of light, thus producing different visual effects, resulting in differences in light and shade even for the same color on the surface of the aluminum shell, so that there are color differences between different parts of the surface of the base material layer 1.
[0022] In the technical solution of the present utility model, the sand oxidation layer includes at least two sand oxidation sections 2 with different surface roughnesses. The sand oxidation layers with different surface roughnesses correspond to different shades of color, so that there are color differences between different parts of the surface of the base material layer 1, meeting the requirement of product appearance diversification; at the same time, each base material layer 1 is an integrally formed structure, which can ensure the overall structural strength and durability of the housing structure 100.
[0023] For the above housing structure 100, please refer to Figure 2 , the present utility model also proposes a processing technology method (taking a two-color aluminum shell as an example): First, an integrally formed base material layer 1 is obtained through processes such as stretching or CNC. Then, the entire base material layer 1 is sandblasted once. After completing the first sandblasting, the base material layer 1 is fixed by an auxiliary fixture, and a part of the surface of the base material layer 1 is wrapped with a protective film 3. Then, secondary sandblasting is carried out. After completing the secondary sandblasting, the protective film 3 is removed. Finally, anodization is carried out to form a sand oxidation layer on the surface of the base material layer 1 to obtain the final housing structure 100.
[0024] Among them, different coarseness of sand is used in the first sandblasting and the second sandblasting, so that the substrate layer 1 has sand oxidation segments 2 with different surface roughnesses after anodization, thereby causing color differences between different parts of the surface of the substrate layer 1. It should be noted that the sand used in the second sandblasting needs to be "coarser" than the sand used in the first sandblasting, that is, the particle size of the sand is larger. For example, if fine sand is used in the first sandblasting, medium sand or coarse sand can be used in the second sandblasting. However, if medium sand is used in the first sandblasting, only coarse sand can be used in the second sandblasting, so that the second sandblasting will be effective; if coarse sand is used in the first sandblasting and fine sand is used in the second sandblasting, the influence on the surface roughness of the substrate layer 1 is small, and the overall surface roughness of the substrate layer 1 is relatively close after anodization, and there will be no color difference. In addition, more sandblasting operations can also be carried out. For example, first spray fine sand, then medium sand, and finally coarse sand. During the sandblasting process, the corresponding parts are wrapped by the protective film 3. By using three or more different coarsenesses of sand, color differences exist between multiple different parts of the surface of the substrate layer 1, and finally a multi-color aluminum shell is obtained.
[0025] Specifically, in an embodiment of the present utility model, at least one sand oxidation segment 2 of the sand oxidation layer is a fine sand layer 21, and at the same time, at least one sand oxidation segment 2 of the sand oxidation layer includes a fine sand layer 21 and a coarse sand layer 22 stacked in sequence on the substrate layer 1. Thus, at least two sand oxidation segments 2 with color differences exist on the surface of the substrate layer 1, meeting the requirements of diversified product appearance. Corresponding to the above processing technology method, that is, the first sandblasting is fine sand and the second sandblasting is coarse sand. The particles of the fine sand are smaller. Spraying fine sand first causes less wear on the substrate layer 1 and can also provide a more delicate surface treatment; spraying coarse sand later can reduce the impact of the coarse sand on the substrate layer 1 and can also quickly form an obvious texture effect. In another embodiment of the present utility model, at least one sand oxidation segment 2 of the sand oxidation layer includes a fine sand layer 21, a medium sand layer, and a coarse sand layer 22 stacked in sequence on the substrate layer 1, that is, the surface of the substrate layer 1 is sandblasted at least three times. In this case, at least one sand oxidation segment 2 of the sand oxidation layer is a fine sand layer 21, and at least one sand oxidation segment 2 of the sand oxidation layer is a fine sand layer 21 and a medium sand layer stacked on the substrate layer 1. That is, at least three sand oxidation segments 2 with color differences exist on the surface of the substrate layer 1, and a multi-color housing structure 100 is obtained.
[0026] It can be understood that in the case of multiple sandblasting operations, at least one sand oxidation segment 2 will include at least two sandblasting layers, and each sandblasting layer is stacked in sequence on the substrate layer 1. And because the sand used in the second sandblasting needs to be "coarser" than the sand used in the first sandblasting, the surface roughness of each sandblasting layer will gradually increase along the direction away from the substrate layer 1. In addition, the sand oxidation segments 2 with different surface roughnesses also have different touch feelings for users in the case of different shades of color. The corresponding product can set sand oxidation segments 2 with different surface roughnesses according to the position and function of the functional area.
[0027] Further, in an embodiment of the present utility model, please refer to Figure 1 , the sand oxidation sections 2 are sequentially connected. In this case, two sand oxidation sections 2 with different surface roughnesses are connected, making the color difference between these two sand oxidation sections 2 more obvious and increasing the aesthetic appeal of the product. In another embodiment of the present utility model, the sand oxidation sections 2 are sequentially arranged at intervals along the extension direction of the base material layer 1. The sand oxidation sections 2 arranged at intervals can provide a visual sense of layering on the product surface. In addition, in other embodiments of the present utility model, it can also be that two sand oxidation sections 2 with different surface roughnesses are grouped in pairs, and then multiple groups are sequentially arranged at intervals along the extension direction of the base material layer 1, or other arrangement methods. The specific arrangement method can be designed according to the functional requirements and aesthetic requirements of the product.
[0028] Considering that the base material layer 1 will be anodized during anodic oxidation, the abrasive used for sandblasting is preferably an abrasive that does not introduce iron contamination. Therefore, in an embodiment of the present utility model, the material of the sand oxidation layer is alumina or glass beads. Alumina has high hardness and good wear resistance; glass beads can provide a smoother and more uniform surface treatment effect.
[0029] The present utility model also proposes an electronic product, which includes the above-mentioned housing structure 100. The specific structure of the housing structure 100 refers to the above-mentioned embodiments. Since this electronic product adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.
[0030] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
