Embodiments of the disclosure described herein relate to a housing having a pattern formed thereon, an electronic device including the housing, and a method for manufacturing the housing.
The housing of an electronic device may have a pattern or design formed on a surface thereof to provide an aesthetic sense to a user. The pattern or design may express texture. The housing may be formed of a metallic material. In general, the housing formed of a metallic material may be manufactured by using an injection mold. The housing may be manufactured after the pattern is formed on the mold through mechanical machining such as CNC.
The housing may include a metal portion and an insulating portion that insulates part of the metal portion. In this case, the pattern is formed on only the metal portion and is cut off by the insulating portion. An additional pattern may be formed on the insulating portion. However, the additional pattern may not be continuously connected with the pattern formed on the metal portion.
The mold is repeatedly used in an injection-molding process, and the pattern formed on the mold may be damaged as the injection-molding process is repeated. Due to this, a non-uniform pattern may be formed on the surface of the housing. Furthermore, the shape of the pattern may be limited to prevent damage to the pattern.

The first ridge is formed in a first color, and the first inclined surfaces are formed in a second color.
An electronic device according to an embodiment of the disclosure includes a housing including a first surface, a second surface that faces away from the first surface, and a third surface that surrounds a space between the first surface and the second surface, and a display disposed in the space of the housing so as to be visible through the first surface. The third surface includes a first region including a pattern formed on a surface thereof, a second region formed between the first region and the first surface, and a third region formed between the first region and the second surface. The first region includes a curved surface having the center of curvature located in a direction toward the space of the housing with respect to the third surface.
An electronic device according to an embodiment of the disclosure includes a first plate that forms a first surface of the electronic device, a second plate that faces away from the first plate and that forms a second surface of the electronic device, and a side member that surrounds a space between the first plate and the second plate and that includes an outer surface forming a third surface of the electronic device. The outer surface includes a first edge adjacent to the first plate, a second edge adjacent to the second plate, and a pattern formed between the first edge and the second edge. The side member includes a first metal portion and a second metal portion that are formed of a metallic material and an insulating portion formed of an insulating material and formed between the first metal portion and the second metal portion. The insulating portion forms an insulating region extending from the first edge to the second edge. The pattern has a continuous shape extending from the first metal portion to the second metal portion through the insulating region.
According to the embodiments of the disclosure, the housings of the electronic devices may include a pattern continuously formed on the metal portion and the insulating portion.
In addition, the disclosure may provide various effects that are directly or indirectly recognized.
With regard to description of the drawings, identical or similar reference numerals may be used to refer to identical or similar components.

In an embodiment, the electronic device 100 may include the side member 140 that forms part of an outer surface (e.g., the side surface) of the electronic device 100. In some embodiments, the outer surface may be, or may include, a third surface between a first surface formed by the first plate 120 and a second surface formed by the second plate 180. The side member 140 may contain a metallic material (e.g., metal). The metallic material may include aluminum.
Hereinafter, in describing the side member 140, a direction of surrounding the space between the first plate 120 and the second plate 180 around the z-axis will be referred to as a circumferential direction C of the side member 140.
In an embodiment, the side member 140 may include short side portions 1401 extending in the x-axis direction, long side portions 1402 extending in the y-axis direction, and corner portions 1403 formed between the short side portions 1401 and the long side portions 1402 to connect the short side portions 1401 and the long side portions 1402.

In various embodiments, the short side portions 1401 may have a greater thickness than the long side portions 1402. Here, the thickness may be the height in a direction (e.g., the z-axis direction) perpendicular to the circumferential direction. The thicknesses of the short side portions 1401 and the long side portions 1402 may be related to the curvatures of peripheral portions of the first plate 120 and/or the second plate 180. When peripheral portions of the first plate 120 that are adjacent to the short side portions 1401 have a greater curvature than peripheral portions of the first plate 120 that are adjacent to the long side portions 1402, the short side portions 1401 may have a smaller thickness than the long side portions 1402. Accordingly, in embodiments of the disclosure, the shapes of the short side portions 1401 and the long side portions 1402 of the side member 140 are not limited to those illustrated in the drawing.

As described above with reference to
In various embodiments, the patterned region 141 may have a width of a predetermined percentage of the thickness of each of the portions 1401, 1402, and 1403 of the side member 140. For example, because the short side portions 1401 of the side member 140 have a greater thickness than the long side portions 1402, the patterned regions 141 included in the short side portions 1401 of the side member 140 may also have a greater width than the patterned regions 141 included in the long side portions 1402.
In various embodiments, the widths of the patterned regions 141 included in the short side portions 1401, the long side portions 1402, and the corner portions 1403 of the side member 140 may vary depending on the curvatures of peripheral portions of the first plate (e.g., the first plate 120 of

Likewise, the pattern formed on the first metal region 1441 may continuously extend to the third metal region 1443 through the second insulating region 1452. Here, when the pattern continuously extends, it may mean that structures (e.g., valleys and ridges) forming the pattern are integrally formed and have a continuous shape.
In various embodiments, the side member 140 may include an opening 149 formed in the patterned region 141. The opening 149 may be formed in the patterned region 141 included in at least one of the short side portions 1401, the long side portions 1402, or the corner portions 1403.

In various embodiments, region 1-1 5421 and/or region 2-1 5431 may be formed to be a curved surface. The curved surface may have a different curvature from the curved surface of the patterned region 541. For example, region 1-1 5421 may have a first curvature, region 2-1 5431 may have a second curvature, and the patterned region 541 may have a third curvature. The first curvature and the second curvature may be greater than the third curvature. Furthermore, the first curvature and the second curvature may be the same as each other.
In various embodiments, the patterned region 541 may be connected with the first region 542 to form a first angle θ1. The angle formed by the first region 542 and the patterned region 541, when viewed in the sectional view, may be an angle between a line extending in a tangential direction from an end portion of the curved surface of the first patterned region 541 and a line extending from an end portion of the first region 542. Alternatively, the angle may be an angle between a normal vector to the end portion of the first region 542 and a normal vector to the end portion of the first patterned region 541.
In various embodiments, the patterned region 541 may be connected with the second region 543 to form a second angle θ2. The angle formed by the first region 542 and the patterned region 541, when viewed in the sectional view, may be an angle between a line extending in a tangential direction from an end portion of the curved surface of the first patterned region 541 and a line extending from an end portion of the first region 542. Alternatively, the angle may be an angle between a normal vector to the end portion of the first region 542 and a normal vector to the end portion of the first patterned region 541.
A side member may include an aluminum containing body and an aluminum oxide containing film formed on a surface of the body. A pattern may be formed on the body through CNC machining before the film is formed. The film may prevent corrosion of the aluminum body. When the angles (e.g., the first angle θ1 and the second angle θ2) between a patterned region (e.g., the patterned region 541) and regions (e.g., the first region 542 and the second region 543) extending from the patterned region are small, the film may be easily separated (delaminated) from the aluminum body, and corrosion of the aluminum body may proceed. Particularly, the film may be easily separated (delaminated) from the edge portion formed by region 1-1 5421 and the patterned region 541 and the edge portion formed by region 2-1 5431 and the patterned region 541.
In contrast, the electronic device 100 or 200 according to various embodiments may include the side member 540 in which the patterned region 541 is formed to be a curved surface and is connected, at relatively large angles, with regions (e.g., the first region 542 and the second region 543) extending from the patterned region 541. Thus, the electronic device 100 or 200 may have an advantageous effect that a film is not easily separated from a body.

The first pattern 610 may include the first valley 6121 and the second valley 6122 adjacent to the first valley 6121. The first pattern 610 may include the second ridge 6132 formed between the first valley 6121 and the second valley 6122 and the first ridge 6131 adjacent to the second ridge 6132. The first pattern 610 may include inclined surfaces 614 extending from the plurality of valleys 6121 and 6122 to the adjacent ridges 6131 and 6132.
In the illustrated embodiment, the ridges 613 of the first pattern 610 may be edges that the first inclined surfaces 614 and the second inclined surfaces 614 substantially meet to form.

The second pattern 620 may include the first valley 6221 and the second valley 6222 adjacent to the first valley 6221. The second pattern 620 may include a second ridge 6232 formed between the first valley 6221 and the second valley 6222 and a first ridge 6231 adjacent to the second ridge 6232.

In various embodiments, the films 615 and 625 may preferably be brought into contact with the metal bodies 616 and 626 over a wide area. When the films 615 and 625 are brought into contact with the metal bodies 616 and 626 over a wide area, a sufficient adhesive force may be provided between the metal bodies 616 and 626 and the films 615 and 625. When a sufficient adhesive force is not provided between the films 615 and 625 and the metal bodies 616 and 626, the films 615 and 625 may be partly removed (e.g., delaminated) from the metal bodies 616 and 626, and corrosion of the metal bodies 616 and 626 (e.g., side members) may start from the removed portions. The side member may affect the appearance of the electronic device in that the side member forms the exterior (e.g., the third surface or the side surface) of the electronic device. In particular, when the patterns 610 and 620 are formed on the side member, the films 615 and 625 formed on protruding portions (e.g., the ridges 613 and 623) of the patterns 610 and 620 may be easily removed.
From this point of view, unlike the first pattern 610, the second pattern 620 illustrated in
When the electronic device is grasped by a user, the side surface of the electronic device may be mainly brought into contact with the user's hand. A pattern that forms a portion of the side surface of the electronic device may scratch the user's hand depending on shapes.

In process 1311, the insulating region may be formed by attaching an insulating material to the workpiece formed of a metallic material. For example, the metallic material may include aluminum, and the insulating material may include a polymer material. For example, an insulating portion may be injection-molded on the workpiece containing aluminum by injection of the polymer material. Thereafter, the insulating region of the insulating portion that forms the surface of the workpiece may be formed.
In process 1313, the pattern may be formed on the surface of the workpiece on which the insulating region is formed. The pattern may be formed by a CNC process including a cutting tool for cutting a portion of the surface of the workpiece. The cutting tool may vary depending on the shape of the pattern. The CNC process may be configured such that the cutting tool continuously cuts the metal portion forming the surface of the workpiece and the insulating portion (e.g., the insulating region).
In process 1315, the opening may be formed in a portion of the surface of the workpiece. The opening may be formed in the region where the pattern is formed or in the region where the pattern is not formed.
In another embodiment, process 1313 may be performed after process 1315 is performed. For example, the pattern may be formed (1313) after the opening is formed in a portion of the surface of the workpiece on which the insulating region is formed (1315). The pattern may extend across the insulating region and the opening.
In process 1317, the housing may be manufactured by forming the film on the surface of the workpiece. The film may contain a compound including metal atoms contained in the workpiece. That is, the film is not formed on the insulating region that does not include the metal atoms.
Referring to
In process 1321, the insulating region may be formed by attaching an insulating material to the workpiece formed of a metallic material. For example, the metallic material may include aluminum, and the insulating material may include a polymer material. For example, an insulating portion may be injection-molded on the workpiece containing aluminum by injection of the polymer material. Thereafter, the insulating region of the insulating portion that forms the surface of the workpiece may be formed.
In process 1323, the patterned layer may be formed on the surface of the workpiece on which the insulating region is formed. The patterned layer may be formed by a CNC process using a cutting tool for cutting a portion of the surface of the workpiece. The cutting tool may vary depending on the shape of the patterned layer. The CNC process may be configured such that the cutting tool continuously cuts the metal portion forming the surface of the workpiece and the insulating portion (e.g., the insulating region).
In process 1325, the first film may be formed on a surface of the patterned layer. The first film may contain a compound including metal atoms contained in the workpiece. For example, the workpiece may contain aluminum, and the first film may contain aluminum oxide. Process 1325 may further include a dye injection process for forming a color on the first film. The dye injection process may include forming pores in the surface of the first film, injecting a first dye related to a first color into the pores, and sealing the first film.
In process 1327, a portion of the patterned layer may be removed. The portion of the patterned layer may be removed by a cutting process. The removed portion may include a portion of the workpiece and a portion of the first film. For example, portions of ridges of the patterned layer and portions of ridges of the first film may be removed.
In process 1329, the second film may be formed on the surface of the patterned layer. The second film may be formed on a region of the surface of the workpiece that is exposed to the outside by removal of the first film. The second film may contain a compound including metal atoms contained in the workpiece. Process 1329 may further include a dye injection process for forming a color on the second film. The dye injection process may include forming pores in the surface of the second film, injecting a second dye related to a second color into the pores, and sealing the second film. The second dye may differ from the first dye.
In a comparative example, a patterned metal workpiece is manufactured by injecting a metallic material into a mold having a pattern formed therein, and an insulating region is injection-molded on the workpiece by injection of a polymer.
In this case, no pattern is formed on the insulating region, and therefore the continuous pattern is cut off by the insulating region. Furthermore, in the injection molding process, injection materials may be formed around the insulating region. The injection materials may be unintentionally formed in valleys of the pattern. Moreover, an additional pattern may be formed on the insulating region through a separate process, but it is difficult to provide continuity with the original pattern. Here, the continuity of the pattern may mean, for example, a shape in which ridges and valleys are accurately connected to provide an aesthetic sense of unity to a user. Particularly, in a case of a fine pattern, the original pattern and the additional pattern may not be continuously connected. According to the comparative example, it may be difficult to implement an aesthetic sense generated from a continuous pattern.
According to the embodiment of the disclosure, the pattern may be formed on the workpiece including the insulating region. Accordingly, the pattern having a continuous shape may be provided, and thus an aesthetic sense may be provided to a user.

A second film 1435 may be formed on the region (e.g., the ridges) where the first film 1433 is not formed on the surface of the metal body 1400. The second film 1435 may not be formed on the region (e.g., the valleys 1434) covered by the first film 1433 and may be formed on only the region (e.g., the ridges) where the metal body 1400 is exposed.
