特開２００４−１２９０１０号公報Japanese Unexamined Patent Publication No. 2004-129010

スマートフォンやポータブルコンピュータなどの電子機器では、種々の無線通信規格用のアンテナが設けられているが、無線通信用の周波数帯域は広域化が進んでいる。 Electronic devices such as smartphones and portable computers are provided with antennas for various wireless communication standards, but the frequency band for wireless communication is becoming wider.

本開示は、大型化を抑制しつつ、無線通信周波数帯域の広域化に対応可能な電子機器を提供する。 The present disclosure provides an electronic device capable of widening a wide area of a wireless communication frequency band while suppressing an increase in size.

本開示の電子機器は、電子部品を収容するケースを有する。
ケースは、対向する一対の主面部と複数の側面部とを有する。
複数の側面部のうち少なくとも２つの隣り合う側面部が単一の側面部材で構成されている。
側面部材の内面にアンテナが設けられている。 The electronic device of the present disclosure has a case for accommodating an electronic component.
The case has a pair of main surface portions and a plurality of side surface portions that face each other.
At least two adjacent side surfaces of the plurality of side surfaces are composed of a single side surface member.
An antenna is provided on the inner surface of the side member.

本開示では、電子機器のケースの側面部材の内面にアンテナを設けているので、ケース内の電子部品の収容スペースに与える影響が少ない。また、隣り合う少なくとも２つの側面部を単一の側面部材で構成したので、これらの少なくとも２つの側面部の内面を連続的に使用してアンテナを配置できる。そのため、複数の側面の各々が個別の部材で構成されている場合と比べ、ケースの寸法が同じ場合でも、アンテナの配置可能領域を増大できる。よって、大型化を抑制しつつ対応周波数帯域を広域化できる。 In the present disclosure, since the antenna is provided on the inner surface of the side member of the case of the electronic device, the influence on the storage space of the electronic component in the case is small. Further, since at least two adjacent side surface portions are composed of a single side surface member, the antenna can be arranged by continuously using the inner surfaces of these at least two side surface portions. Therefore, the area in which the antenna can be arranged can be increased even when the dimensions of the case are the same, as compared with the case where each of the plurality of side surfaces is composed of individual members. Therefore, it is possible to widen the corresponding frequency band while suppressing the increase in size.

The side surface portion 10e and the right side surface portion 10f are composed of a single third side surface member 13.

第１側面部材１２や第２側面部材１４の内側には、外部機器接続用のコネクタ（図示せず）が収容されており、第１側面部材１２や第２側面部材１４に設けられた蓋（図示せず）を開閉することで、コネクタにアクセス可能となっている。 A connector (not shown) for connecting an external device is housed inside the first side surface member 12 and the second side surface member 14, and a lid (not shown) provided on the first side surface member 12 and the second side surface member 14 is accommodated. The connector can be accessed by opening and closing (not shown).

第３側面部材１３は、上記のような蓋等は設けられていないが、内面１３ｉが、無線通信用のアンテナ２０の配置領域（アンテナ配置領域Ａｒ）として利用される。アンテナ２０は、使用周波数帯域が異なる第１アンテナ２１、第２アンテナ２２、及び第３アンテナ２３を含む。 The third side surface member 13 is not provided with a lid or the like as described above, but the inner surface 13i is used as an arrangement area (antenna arrangement area Ar) of the antenna 20 for wireless communication. The antenna 20 includes a first antenna 21, a second antenna 22, and a third antenna 23 having different frequency bands used.

図３は、第３側面部材１３を内面１３ｉ側から見た斜視図である。図４は、第３側面部材１３の右側面部１０ｆの断面図（図３のＡ−Ａ線による断面）である。なお、第３側面部材１３の下側面部１０ｅの断面は右側面部１０ｆの断面とほぼ同じであるため、図示を省略する。第３側面部材１３は、電波透過性を有する樹脂製であり、射出成形により形成されている。右側面部１０ｆと下側面部１０ｅとが一体的に射出成形により形成されることで、第３側面部材１３の内面１３ｉは、右側面部１０ｆと下側面部１０ｅとの間に継ぎ目がない連続した面となっている。 FIG. 3 is a perspective view of the third side surface member 13 as viewed from the inner surface 13i side. FIG. 4 is a cross-sectional view of the right side surface portion 10f of the third side surface member 13 (cross section taken along the line AA of FIG. 3). Since the cross section of the lower side surface portion 10e of the third side surface member 13 is substantially the same as the cross section of the right side surface portion 10f, the illustration is omitted. The third side surface member 13 is made of a resin having radio wave transmission and is formed by injection molding. Since the right side surface portion 10f and the lower side surface portion 10e are integrally formed by injection molding, the inner surface 13i of the third side surface member 13 is a continuous surface having no seam between the right side surface portion 10f and the lower side surface portion 10e. It has become.

第１アンテナ２１、第２アンテナ２２、及び第３アンテナ２３は、上記のような第３側面部材１３の内面１３ｉに、レーザ直接構造化（ＬＤＳ）技術を利用した金属めっきにより形成されている。 The first antenna 21, the second antenna 22, and the third antenna 23 are formed on the inner surface 13i of the third side surface member 13 as described above by metal plating using laser direct structuring (LDS) technology.

第１アンテナ２１、第２アンテナ２２、及び第３アンテナ２３は、概ね右側面部１０ｆ及び下側面部１０ｅの内面１３ｉの長手方向に沿って延びている。第１アンテナ２１、第２アンテナ２２、及び第３アンテナ２３は、種々の無線ＬＡＮ規格やＬＴＥ規格等に基づく使用周波数帯域に対応可能に構成されている。 The first antenna 21, the second antenna 22, and the third antenna 23 extend substantially along the longitudinal direction of the inner surface 13i of the right side surface portion 10f and the lower side surface portion 10e. The first antenna 21, the second antenna 22, and the third antenna 23 are configured to be compatible with the frequency band used based on various wireless LAN standards, LTE standards, and the like.

第３側面部材１３の右側面部１０ｆは、前面部１０ａ及び後面部１０ｂ側の部分が湾曲するように構成され、縦面部１０ｆａと、湾曲部１０ｆｂ，１０ｆｃとを有する。縦面部１０ｆａは、前面部１０ａに垂直である。湾曲部１０ｆｂは、縦面部１３ｆａと前面部１０ａとの間で円弧状に延びる曲面であり、円弧状の断面を有する。湾曲部１０ｆｃは、縦面部１３ｆａと後面部１０ｂとの間で円弧状に延びる曲面であり、円弧状の断面を有する。 The right side surface portion 10f of the third side surface member 13 is configured so that the front surface portion 10a and the rear surface portion 10b side portions are curved, and has a vertical surface portion 10fa and curved portions 10fb and 10fc. The vertical surface portion 10fa is perpendicular to the front surface portion 10a. The curved portion 10fb is a curved surface extending in an arc shape between the vertical surface portion 13fa and the front surface portion 10a, and has an arc-shaped cross section. The curved portion 10fc is a curved surface extending in an arc shape between the vertical surface portion 13fa and the rear surface portion 10b, and has an arc-shaped cross section.

第３側面部材１３の下側面部１０ｅは、前面部１０ａ及び後面部１０ｂ側の部分が湾曲するように構成され、縦面部１０ｅａと、湾曲部１０ｅｂ，１０ｅｃとを有する。縦面部１０ｅａは、前面部１０ａに垂直である。湾曲部１０ｅｂは、縦面部１３ｅａと前面部１０ａとの間で円弧状に延びる曲面であり、円弧状の断面を有する。湾曲部１０ｅｃは、縦面部１３ｅａと後面部１０ｂとの間で円弧状に延びる曲面であり、円弧状の断面を有する。 The lower side surface portion 10e of the third side surface member 13 is configured so that the front surface portion 10a and the rear surface portion 10b side portions are curved, and has a vertical surface portion 10ea and curved portions 10eb and 10ec. The vertical surface portion 10ea is perpendicular to the front surface portion 10a. The curved portion 10eb is a curved surface extending in an arc shape between the vertical surface portion 13ea and the front surface portion 10a, and has an arcuate cross section. The curved portion 10ec is a curved surface extending in an arc shape between the vertical surface portion 13ea and the rear surface portion 10b, and has an arc-shaped cross section.

第３側面部材１３の右側面部１０ｆ及び下側面部１０ｅのうち、これらが接続される部分である接続部１３ｃは、曲面部１３ｃａ，１３ｃｂ，１３ｃｃで構成されている。曲面部１３ｃａは、右側面部１０ｆの縦面部１０ｆａと下側面部１０ｅの縦面部１０ｅａとを滑らかに繋ぐ（接続する）曲面形状を有する。曲面部１３ｃｂは、右側面部１０ｆの湾曲部１０ｆｂと下側面部１０ｅの湾曲部１０ｅｂと曲面部１３ｃａとを滑らかに繋ぐ（接続する）曲面形状を有する。曲面部１３ｃｃは、右側面部１０ｆの湾曲部１０ｆｃと下側面部１０ｅの湾曲部１０ｅｃと曲面部１３ｃａとを滑らかに繋ぐ（接続する）曲面形状を有する。 Of the right side surface portion 10f and the lower side surface portion 10e of the third side surface member 13, the connecting portion 13c, which is a portion to which these are connected, is composed of curved surface portions 13ca, 13cc, and 13cc. The curved surface portion 13ca has a curved surface shape that smoothly connects (connects) the vertical surface portion 10fa of the right side surface portion 10f and the vertical surface portion 10ea of the lower side surface portion 10e. The curved surface portion 13cc has a curved surface shape that smoothly connects (connects) the curved portion 10fb of the right side surface portion 10f, the curved portion 10eb of the lower side surface portion 10e, and the curved surface portion 13ca. The curved surface portion 13cc has a curved surface shape that smoothly connects (connects) the curved portion 10fc of the right side surface portion 10f, the curved portion 10ec of the lower side surface portion 10e, and the curved surface portion 13ca.

第１アンテナ２１は、湾曲部１０ｆｂ，１０ｅｂ（接続部１３ｃの曲面部１３ｃｂを含む）の内面１３ｉに形成されている。第２アンテナ２２は、縦面部１０ｆａ，１０ｅａ（接続部１３ｃの曲面部１３ｃａを含む）の内面１３ｉに形成されている。第３アンテナ２３は、縦面部１０ｆａ，１０ｅａ、湾曲部１０ｆｃ，１０ｅｃ（接続部１３ｃの曲面部１３ｃａ，１３ｃｃを含む）の内面１３ｉに形成されている。 The first antenna 21 is formed on the inner surface 13i of the curved portions 10fb and 10eb (including the curved surface portion 13cc of the connecting portion 13c). The second antenna 22 is formed on the inner surface 13i of the vertical surface portions 10fa and 10ea (including the curved surface portion 13ca of the connecting portion 13c). The third antenna 23 is formed on the inner surface 13i of the vertical surface portions 10fa, 10ea and the curved portions 10fc, 10ec (including the curved surface portions 13ca, 13cc of the connecting portion 13c).

接続部１３ｃを、曲面形状を有する曲面部１３ｃａ，１３ｃｂ，１３ｃｃで構成したことで、第１アンテナ２１、第２アンテナ２２、及び第３アンテナ２３の曲げの曲率を小さくできる。そのため、直交する右側面部１０ｆ及び下側面部１０ｅに第１アンテナ２１、第２アンテナ２２、及び第３アンテナ２３を設けた場合でも、良好なアンテナ特性を得ることができる。 By configuring the connecting portion 13c with curved surface portions 13ca, 13cc, and 13cc having a curved surface shape, the bending curvature of the first antenna 21, the second antenna 22, and the third antenna 23 can be reduced. Therefore, even when the first antenna 21, the second antenna 22, and the third antenna 23 are provided on the right side surface portion 10f and the lower side surface portion 10e that are orthogonal to each other, good antenna characteristics can be obtained.

図５は、比較例のポータブルコンピュータの外観を示す斜視図である。比較例のポータブルコンピュータ１００のケース１１０は、左側面部１１０ｄを構成する第１側面部材１１２、上側面部１１０ｃを構成する第２側面部材１１４、右側面部１１０ｆを構成する第３側面部材１１３、及び下側面部１１０ｅを構成する第４側面部材１１５を有している。比較例のケース１１０では、実施の形態１のケース１０とは異なり、右側面部１１０ｆを構成する部材と下側面部１１０ｅを構成する部材とが個別に設けられている。 FIG. 5 is a perspective view showing the appearance of the portable computer of the comparative example. The case 110 of the portable computer 100 of the comparative example has a first side surface member 112 forming the left side surface portion 110d, a second side surface member 114 forming the upper side surface portion 110c, a third side surface member 113 forming the right side surface portion 110f, and a lower portion. It has a fourth side surface member 115 that constitutes the side surface portion 110e. In the case 110 of the comparative example, unlike the case 10 of the first embodiment, the members constituting the right side surface portion 110f and the members constituting the lower side surface portion 110e are individually provided.

ここで、レーザ直接構造化（ＬＤＳ）技術では複数の部材にまたがってアンテナを形成することは困難である。そのため、比較例のケース１１０の場合、アンテナを形成することができる領域Ａｒｄは、例えば、図５に示すように第３側面部材１１３の内面のみとなり、十分な面積や長さを得ることができない。 Here, it is difficult to form an antenna across a plurality of members by laser direct structuring (LDS) technology. Therefore, in the case of Case 110 of the comparative example, the region Ard in which the antenna can be formed is, for example, only the inner surface of the third side surface member 113 as shown in FIG. 5, and a sufficient area and length cannot be obtained. ..

本開示の発明者は、これについて種々の検討を行い、隣接する下側面部１０ｅと右側面部１０ｆとを単一の第３側面部材１３で構成するとともに、第３側面部材１３の内面１３ｉにアンテナ２０を設けるという構成の知見を得た。これにより、複数の側面部が個別の部材で構成されている場合と比べ大きなアンテナ配置領域Ａｒを構成できる。したがって、無線通信において使用可能な周波数帯域を広域化できる。また、ケース１０内の空間を、電子部品類を配置するための空間として有効に利用できる。 The inventor of the present disclosure has made various studies on this, and has formed the adjacent lower side surface portion 10e and the right side surface portion 10f by a single third side surface member 13, and has an antenna on the inner surface 13i of the third side surface member 13. We obtained the knowledge of the configuration that 20 is provided. As a result, it is possible to form a large antenna arrangement region Ar as compared with the case where the plurality of side surface portions are composed of individual members. Therefore, the frequency band that can be used in wireless communication can be widened. Further, the space inside the case 10 can be effectively used as a space for arranging electronic parts.

また、本実施形態では、第３側面部材１３の右側面部１０ｆ及び下側面部１０ｅにおける、前面部１０ａ及び後面部１０ｂ側の部分（湾曲部１０ｆｂ，１０ｆｃ，１０ｅｂ，１０ｅｃ）を湾曲させたことで、例えば縦面部１０ｆａ，１０ｅａを直線的に延長した場合よりも、第３側面部材１３の内面１３ｉの面積を増大させることができる。つまり、アンテナ配置領域Ａｒを拡張し、より多くのアンテナを配置することができる。 Further, in the present embodiment, the front surface portion 10a and the rear surface portion 10b side portions (curved portions 10fb, 10fc, 10eb, 10ec) of the right side surface portion 10f and the lower side surface portion 10e of the third side surface member 13 are curved. For example, the area of the inner surface 13i of the third side surface member 13 can be increased as compared with the case where the vertical surface portions 10fa and 10ea are linearly extended. That is, the antenna arrangement area Ar can be expanded to arrange more antennas.

［２．効果等］
本実施の形態のポータブルコンピュータ１（電子機器の一例）は、電子部品を収容するケース１０を有する。
ケース１０は、対向する前面部１０ａ及び後面部１０ｂ（一対の主面部）と、上側面部１０ｃ、左側面部１０ｄ、下側面部１０ｅ，及び右側面部１０ｆ（複数の側面部）とを有する。
上側面部１０ｃ、左側面部１０ｄ、下側面部１０ｅ，及び右側面部１０ｆのうち下側面部１０ｅ及び右側面部１０ｆ（少なくとも２つの隣り合う側面部）が第３側面部材１３（単一の側面部材）で構成されている。

Further, since the adjacent lower side surface portion 10e and the right side surface portion 10f are composed of a single third side surface member 13, the antenna 20 is provided by continuously using the inner surface 13i of the lower side surface portion 10e and the right side surface portion 10f. be able to. Therefore, a large antenna arrangement region Ar can be formed as compared with the case where each of the plurality of side surface portions is composed of individual members.

At least a part of the antenna 20 is provided on the inner surface 13i of the curved portions 10fb, 10fc, 10eb, and 10ec.

これにより、湾曲部１０ｆｂ，１０ｆｃ，１０ｅｂ，１０ｅｃが設けられていない場合と比べ、第３側面部材１３の内面１３ｉの面積を増大させ、アンテナ配置領域Ａｒを拡張することができる。 As a result, the area of the inner surface 13i of the third side surface member 13 can be increased and the antenna arrangement region Ar can be expanded as compared with the case where the curved portions 10fb, 10fc, 10eb, and 10ec are not provided.

隣り合う縦面部１０ｅａ，１０ｆａ同士が接続される部分は、曲面形状を有する曲面部１３ｃａ（第１の曲面部）で構成されている。

It has vertical surface portions 10ea and 10fa, and adjacent vertical surface portions 10ea and 10fa are connected to each other.
The portion where the adjacent vertical surface portions 10ea and 10fa are connected to each other is composed of a curved surface portion 13ca (first curved surface portion) having a curved surface shape.
At least a part of the antenna 20 is provided on the inner surface 13i of the curved surface portion 13ca (first curved surface portion).
