Description

Technical Field

[0001] The utility model relates to the field of electronics, in particular to a casing plate. Background Art

[0002] Traditional computer cases usually form a protective film layer on their surface through electroplating, anodizing, or chemical treatment, which not only achieves corrosion protection but also provides appearance color design.

[0003] Traditionally, electroplating, anodizing, or chemical treatment is performed in batches as a wet process. The common method is to clamp one side of the housing with a fixture, hang it on a rack, and then immerse it in a chemical tank in batches to grow a protective film layer.

[0004] However, since the part clamped by the fixture is prone to uneven growth of the protective film layer, which will cause uneven appearance, the edges are usually cut to retain other areas where the film is completed. However, these cut areas may become areas of rust and stress concentration. For corrosion prevention and aesthetics, the current common method is to add a plastic or rubber protective block for protection. However, it also directly affects the size limit of lightweight and thin. Utility Model Content

[0034] In the following description, the terms "first", "second", "third" are used only to distinguish one element, component, region, layer or part from another element, component, region, layer or part, rather than to indicate a necessary order of precedence. In addition, relative terms such as "lower" and "upper", "inner" and "outer" may be used herein to describe the relationship between one element and another element, and it should be understood that the relative terms are intended to include different orientations of the device in addition to the orientation shown in the figure. For example, if a device in a figure is turned over, the element described as being on the "lower" side of the other elements will be oriented on the "upper" side of the other elements. This only represents a relative orientation relationship, not an absolute orientation relationship.

[0035] In the accompanying drawings, for the sake of clarity, the width of some elements, regions, etc. is magnified. Throughout the specification, the same reference numerals represent the same elements. It should be understood that when, for example, an element is referred to as being "on" or "connected to" another element, it may be directly on or connected to another element, or an intermediate element may also exist. On the contrary, when an element is referred to as being "directly on" or "directly connected to" another element, there is no intermediate element.

[0036] Figure 1 It is a top view of a first embodiment of a casing plate. Figure 2 for Figure 1 A cross-sectional view of an embodiment of the AA section. Figure 3 A partially enlarged schematic diagram of the process for hanging rigid panels. Figure 4 for Figure 1 A cross-sectional view of an embodiment of the BB section. Figures 1 to 4 As shown, in the first embodiment, the housing plate 1 includes a rigid plate 10 and an inorganic protective layer 20. The rigid plate 10 includes a first surface 11, a second surface 13, and a circumferential wall 15. The first surface 11 is opposite to the second surface 13, and the circumferential wall 15 connects the first surface 11 and the second surface 13. The distance D between the first surface 11 and the second surface 13, that is, the thickness of the rigid plate 10 is 0.6 to 1.8 mm. Preferably, in some embodiments, the distance D between the first surface 11 and the second surface 13 is 0.8 to 1.5 mm. The housing plate 1 can be mainly used in the housing of a notebook computer or a tablet computer.

[0037] Here, the first surface 11 is generally the surface of the housing plate 1 facing outward. At least two dovetail grooves 17 are formed on the second surface 13, and the depth of the dovetail grooves 17 is 0.3 to 1.2 mm. Preferably, in some embodiments, the depth of the dovetail grooves 17 is 0.4 to 0.6 mm, that is, the dovetail grooves 17 are approximately half the thickness of the rigid plate 10. The inorganic protective layer 20 completely covers the first surface 11, the second surface 13, the circumferential wall 15, and the bottom surface 171 and the wall surface 173 of each dovetail groove 17.

[0038] Here, the rigid plate 10 is selected from metal plates, plastic steel plates, glass plates, or ceramic plates, and can also be a composite plate of the above materials. In fact, a suitable material can be selected for use according to the required appearance, strength, and toughness, but the above is only an example and is not limited to this. The inorganic protective layer 20 can be a metal layer or a metal compound layer, such as a metal oxide layer, formed by electroplating, anodizing, or chemical treatment to match the material of the rigid plate 10. It provides the color of the appearance and the function of corrosion protection.

[0039] Figure 3 This is a partial enlarged schematic diagram of the process of hanging rigid panels. Figure 3 As shown, the dovetail groove 17 is used as a hanging point for hanging the rigid plate 10 for electroplating, anodizing, and chemical treatment. Usually, the spherical hanger 500 is abutted against the dovetail grooves 17 of the two rigid plates 10. Since the chemical solution in the chemical solution tank has buoyancy, the rigid plate 10 usually has at least two dovetail grooves 17 to ensure the position of the rigid plate 10 when the inorganic protective layer 20 is made. Since it is not clamped on one side of the rigid plate 10 in a clamping manner, the inorganic protective layer 20 can completely cover the outer surface of the rigid plate 10. In addition, since there is a gap between the hanger 500 and the dovetail groove 17, the chemical solution can still flow in, and the inorganic protective layer 20 will also be formed in the dovetail groove 17.

[0040] On the bottom surface 171 and the wall surface 173 of the tail groove 17. In addition, the inorganic protective layer 20 from the first surface 11 to the circumferential wall 15 is continuous, flat and complete, meeting the requirements of the appearance of the housing plate 1.

[0041] Figure 5 for Figure 1 A cross-sectional view of another embodiment of the BB section. Figure 5 As shown, refer to Figure 4 ,like Figure 4 As shown, in some embodiments, the dovetail groove 17 has an oblique angle θ on both sides, and Figure 5As shown, in some embodiments, the dovetail groove 17 may also have only a single-sided bevel angle θ. Here, the bevel angle θ is the angle between the bottom surface 171 and the wall surface 173 of the dovetail groove 17, which is an acute angle. Preferably, in some embodiments, the bevel angle θ is 20 to 80 degrees. More preferably, in some embodiments, the bevel angle θ is 45 to 60 degrees.

[0042] Figure 6 FIG. 1 is a top view of a second embodiment of a housing plate. In some embodiments, for greater process stability, the rigid plate 10 has four dovetail grooves 17, and the four dovetail grooves are symmetrically arranged on the second surface 13. However, the number of dovetail grooves 17 is only an example and not intended to be limiting.

[0043] Figures 7 to 9 3 to 5 are top views of the casing plate according to the third to fifth embodiments. Figures 7 to 9 As shown, refer to Figure 1 and Figure 5 and Figure 6 Furthermore, the dovetail groove 17 can be designed into different shapes in different embodiments, as long as it can match the hanger 500. For example, Figures 6 to 9 As shown, the bottom surface 171 of the dovetail groove 17 can be a rounded rectangle, a circle, a semi-rounded rectangle, and a semi-circle. However, the above is only an example and not intended to be limiting.

[0044] Through the above detailed description, through the design of the dovetail groove 17 on the rigid panel 10, when making the inorganic protective layer 20, it can be used as a hook point for hanging the rigid panel 10, so that the inorganic protective layer 20 can completely cover the rigid panel 10 without the need for subsequent cutting and processing, thereby improving the aesthetics and avoiding rust, and further achieving a lighter and thinner design.

[0045] Although the technical content of the present invention has been disclosed as above in the preferred embodiment, it is not intended to limit the present invention. Any slight changes and modifications made by anyone familiar with this art without departing from the spirit of the present invention should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be based on the scope defined in the attached claims.
