At least one hole 130 may be formed at one sidewall 119 of the side region 115. The other sidewalls 116, 117, and 118 of the side region 115 may not be provided with the hole 130.
For example, referring to fig. 5, a plurality of holes 130 may be formed at the fourth sidewall 119. Referring to fig. 6, the third sidewall 118 located at the opposite side of the fourth sidewall 119 may not be provided with the hole 130.
Referring to fig. 6, the fourth sidewall 119 includes: a first inner surface 1191 provided with a color layer 160; a first outer surface 1192, which is not provided with a color layer 160; and an aperture edge surface 1193 that is not provided with the color layer 160 and that forms the aperture 130 and connects the first inner surface 1191 with the first outer surface 1192. Since the hole 130 is formed after the color layer 160 is disposed on the inner surface of the transparent case in a state before the hole 130 is formed, the color layer 160 is not disposed on the hole edge surface 1193.
The thickness T1 between the first inner surface 1191 and the first outer surface 1192 of the fourth side wall 119 may vary depending on the position in the front-to-rear direction Z1 and Z2. For example, the thickness T1 between the first inner surface 1191 and the first outer surface 1192 of at least a portion of the fourth side wall 119 may decrease the closer to the front Z1. Here, the thickness T1 between the first inner surface 1191 and the first outer surface 1192 is defined as a thickness in a direction perpendicular to the front-rear direction Z1, Z2 of the fourth side wall 119.
Referring to fig. 7, the third sidewall 118 includes a second inner surface 1181 provided with the color layer 160, and a second outer surface 1182 connected to the second inner surface 1181 and not provided with the color layer 160.
The thickness T2 between the second inner surface 1181 and the second outer surface 1182 of the third sidewall 118 varies depending on the location of the anterior-posterior directions Z1 and Z2. For example, the thickness T2 between the second interior surface 1181 and the second exterior surface 1182 of at least a portion of the third sidewall 118 may decrease closer to the front Z1. Here, the thickness T2 between the second inner surface 1181 and the second outer surface 1182 is defined as a thickness in a direction perpendicular to the front-rear directions Z1 and Z2 of the third side wall 118.
Since the color layer 160 is continuously disposed on the second inner surface 1181 of the third sidewall 118, the color layer 160 is visually recognized from the outside through the transparent third sidewall 118, so that a continuous color sensation can be provided.
In contrast, the hole 130 is formed on the fourth sidewall 119, so that there is a region where the color layer 160 is not continuously disposed at the first inner surface 1191 of the fourth sidewall 119. Also, the color layer 160 is not disposed on the hole edge surfaces 1193 forming the holes 130. Thus, even if the color layer 160 is visually recognized from the outside through the fourth sidewall 119, a continuous color sensation as provided by the third sidewall 118 is not provided.
Specifically, the hole edge surface 1193 on which the color layer 160 is not provided may be visually recognized from the outside through the transparent fourth side wall 119, unlike the color layer 160 provided on the first inner face 1191 of the fourth side wall 119. In particular, the greater the thickness of the aperture edge surface 1193, the more noticeable the discrete color perception caused by such aperture edge surface 1193 when viewed from behind the fourth side wall 119.
As a method of reducing the discontinuous color sensation caused by the hole edge surface 1193, a method of providing the color layer 160 not only on the inner surface of the side region 115 but also on the hole edge surface 1193 may be considered. As described above, in order to provide the color layer 160 to the inner surface of the side region 115 and the hole edge surface 1193, the process of providing the color layer 160 to the transparent housing 110 should be performed after the process of forming the hole 130 to the transparent housing 110. However, in the case where the color layer 160 is provided after the hole 130 is formed in the transparent case 110, a phenomenon in which the color layer 160 is knotted at the hole edge surface 1193 and the hole peripheral region, etc., may occur, which may be the other reason for deteriorating the aesthetic sense instead.
The electronic device 1 according to the embodiment provides a structure of reducing the thickness of the side region 115 where the hole 130 is formed, so that not providing the color layer 160 on the hole edge surface 1193 can also alleviate the hole edge surface 1193 from being visually recognized from the outside in the side region of the transparent housing 110. By reducing the maximum width Tmax of the hole edge 1193 forming the hole 130, the deterioration of the aesthetic sense due to the hole edge surface 1193 being visually recognized from the outside can be alleviated.
The maximum width Tmax of the aperture edge surface 1193 may be of a certain size or less. For example, the maximum thickness Tmax of the aperture rim posterior 1193 may be less than 1.5 mm.
In order to reduce the maximum width Tmax of the hole edge surface 1193, the thickness of the fourth sidewall 119 where the hole 130 is formed may be formed to be smaller than the thickness of the third sidewall 118 where the hole 130 is not formed. A thickness T1 between the first interior surface 1191 and the first exterior surface 1192 may be less than a thickness T1 between the second interior surface 1181 and the second exterior surface 1182.
In the case where the fourth and third sidewalls 119 and 118 have a structure in which the thickness varies in a direction perpendicular to the front-rear directions Z1 and Z2, the maximum thickness T1 between the first inner surface 1191 and the first outer surface 1192 may be smaller than the maximum thickness T2 between the second inner surface 1181 and the second outer surface 1182.
The maximum width Tmax in a direction perpendicular to the front-to-rear directions Z1 and Z2 of the hole edge surfaces 1193 may be smaller than the maximum thickness T1 between the first inner face 1191 and the first outer face 1192.
As an example of reducing the maximum width Tmax of the aperture edge surface 1193, the inclination angle of the first inner surface 1191 may be reduced. The angle of inclination of first inner surface 1191 is defined as the angle of inclination to forward Z1.
The angle of inclination of at least a portion of the first inner surface 119 may vary depending on the location of the front-to-rear directions Z1 and Z2. According to an example, the inclination angle of the portion of first inner surface 1191 connected to inner surface 1111 of rear region 111 varies according to the positions of front-to-rear directions Z1 and Z2, and other portions in first inner surface 1191, for example, the portion of first inner surface 1191 away from rear region 111 may have a constant inclination angle. The minimum inclination angle may occur at a portion of the first surface 1191 having a constant inclination angle.
As described above, in the structure in which the inclination angle of the first inner surface 1191 is changed according to the positions of the front and rear directions Z1 and Z2, the minimum inclination angle of the first inner surface 1191 (hereinafter, referred to as 'first inclination angle') may be reduced.
For example, in a case where at least a portion of the first inner surface 1191 has a curved surface and the inclination angle decreases along the front Z1, the first inclination angle of the first inner surface 119 may be a certain magnitude or less. For example, the first inclination angle of the first inner surface 1191 may be 10 degrees or less.
However, the first inclination angle may be more than a certain angle in consideration of the manufacturing process. For example, in order to stably pull out the transparent housing 110 formed in the injection molding process from the mold, the first inclination angle may be 3 degrees or more. However, in the case where the manufacturing process of the transparent casing 110 is changed, for example, in the case where the development of the mold and the injection molding technology or the processing method is changed, the first inclination angle may be less than 3 degrees.
Referring to fig. 8, the maximum width Tmax of the hole edge surface 1193 may be determined by the minimum width Tmin of the hole edge surface 1193, the height h along the front-rear directions Z1 and Z2 of the hole 130, and the inclination angle θ of the first inner surface 1191 facing the hole 1303. For example, the maximum width Tmax of hole edge surface 1193 may be roughly estimated according to equation (1) below.
The inclination angle θ of the first surface 1191 facing the aperture 1301May be equal to or slightly less than the first inclination angle θ of the first inner surface 11913. Thus, the maximum width Tmax of the edge of the hole 130 can be roughly estimated according to the following equation (2).
Tmax＝Tmin+h·tanθ3； (1)
Tmax＝Tmin+h·tanθ1； (2)
Thus, the difference between the maximum width Tmax of the hole edge surface 1193 and the minimum width Tmin of the hole edge 1193 may be determined by the height h along the front-rear directions Z1 and Z2 of the hole 130 and the inclination angle θ of the first inner surface 1191 as in formula (3)1。
Tmax-Tmin＝h·tanθ1； (3)
If the first inclination angle of the first inner surface 1191 is 3 degrees or more and 10 degrees or less, the difference between the maximum width Tmax of the edge of the hole 130 and the minimum width Tmin of the hole edge surface 1193 may be 0.05 times or more and 0.18 times or less of the height h in the front-rear direction Z1 and Z2 of the hole 130.
The angle of inclination of first interior surface 1191 may be less than the angle of inclination of second interior surface 1181. Here, the inclination angle of the second inner surface 1181 is defined as an inclination angle to the front Z1.
In the case where the inclination angles of the first and second inner surfaces 1191 and 1191 each vary with the position in the front-rear directions Z1 and Z2, the first inclination angle of the first inner surface 1191 may be reduced to a minimum inclination angle that is smaller than the inclination angle at the second inner surface 1181.
A first radius of curvature R1 of a portion of first interior surface 1191 connected to interior surface 1111 of rear region 111 may be less than a second radius of curvature R2 of a portion of second interior surface 1181 connected to interior surface 1111 of rear region 111.
As an example of reducing the maximum width Tmax of the aperture edge surface 1193, the first surface 1192 may be configured to have another configuration.
Fig. 9 is a plan view of the fourth side wall 119 of the transparent cover 110 according to an embodiment, viewed from the upper side. Fig. 10 is a plan view of the fourth side wall 119 of the transparent cover 110 according to an embodiment, viewed from the upper side.
Referring to fig. 9, the first outer surface 1192 of the fourth sidewall 119 may be positioned inward compared to the outer surfaces 1232 and 1242 of the corner walls 123 and 124 disposed at both sides of the fourth sidewall 119.
By recessing at least a part of the region of the fourth side wall 119 inward as compared with the corner walls 123 and 124 provided in the vicinity of the fourth side wall 119, the thickness of the fourth side wall 119 can be reduced and the fourth side wall 119 can be prevented from being damaged by external impact. Since the first outer surfaces are located inward compared to the outer surfaces 1232 and 1242 of the corner walls 123 and 124, the fourth sidewall 119 can be prevented from being damaged by inducing external impacts to the relatively thick corner walls 123 and 124.
However, the first outer surface 1192 is not limited to having to be located inside compared to the outer surfaces of the corner walls 123 and 124. As shown in fig. 10, first outer surface 1192 may also be disposed in the same plane as the outer surfaces of outer surfaces 1232 and 1242 of corner walls 123 and 124.
Referring again to fig. 6 and 7, the third radius of curvature of the portion of the first outer surface 1192 connected to the outer surface 1112 of the posterior region 111 may be less than the fourth radius of curvature of the portion of the second inner surface 1181 connected to the outer surface 1112 of the posterior region 111. However, the radii of curvature of the first outer surface 1192 and the second outer surface 1182 need not be different and may be the same as each other.
In addition, in the above-described embodiment, the example in which the plurality of holes 130 are provided on the fourth side wall 119 is mainly described, however, the number of the holes 130 provided on the fourth side wall 119 may be changed as needed. For example, as shown in fig. 11, a hole 130 may be provided on the fourth side wall 119.
In the above-described embodiment, the transparent housing 110 may be colorless and transparent. Only, the transparent cover 110 is not limited thereto, and the transparent cover 110 may have various colors as long as it has a degree of transparency that the color layer 160 can be visually recognized from the outside. As described above, in the case where the transparent cover 110 itself has a color, the color of the transparent cover 110 and the color of the color layer 160 may overlap each other and be exposed.
In the above-described embodiment, an example in which the transparent casing 110 forms the entire side surface of the electronic apparatus 1 is mainly described. However, the structure of the transparent housing 110 is not limited thereto. For example, the housing structure 100 may further include a metal frame (not shown) disposed between an edge of the display module 10 and the transparent housing 110. Thus, the side surface of the electronic device 1 may be formed by the metal frame and the transparent housing 110.
With the electronic device according to the embodiment and the case structure for the electronic device, it is possible to mitigate the degradation of the aesthetic sense due to the hole by minimizing the thickness of the transparent case formed with the hole.
The embodiments described above are merely exemplary, and those skilled in the art can make various modifications and equivalent other embodiments based on the embodiments. Therefore, the true technical scope of the present invention should be defined based on the technical idea of the invention described in the following claims.
