Description

本発明は、枠状のパッキング部材を使用する防水構造、該防水構造を備えた携帯機器、該携帯機器の製造方法に関する。   The present invention relates to a waterproof structure using a frame-shaped packing member, a portable device having the waterproof structure, and a method for manufacturing the portable device.

近年、携帯電話機に代表される携帯機器は、いつでも、どこでも、だれとでも、というユビキタス社会の到来により様々な使用環境、例えば、水辺での使用が想定される。水辺で使用される携帯機器には、防水構造を備えることが求められる。そこで、防水構造を備えた携帯機器が提案され、特許文献１に開示されている。   In recent years, mobile devices typified by mobile phones are expected to be used in various usage environments, such as waterfronts, due to the arrival of a ubiquitous society wherever and whenever. A portable device used on the waterside is required to have a waterproof structure. Therefore, a portable device having a waterproof structure has been proposed and disclosed in Patent Document 1.

図１２は、特許文献１に開示された携帯機器の斜視図である。図１２に示す携帯機器１００は、下部筐体１０２に上部筐体１０１を重ねることが可能な折り畳み式の携帯電話機である。以下、上部筐体１０１の防水構造について説明する。図１３は、図１２に示す携帯機器１００の上部筐体１０１の分解斜視図である。図１３に示すように、上部筐体１０１は、筐体カバー１１１と、筐体ケース１１２とを有する。筐体カバー１１１と筐体ケース１１２との間には、ゴム製のパッキング部材１０３が挟み込まれている。図１４は、パッキング部材１０３の平面図である。図１４に示すように、パッキング部材１０３は枠状に形成されている。   FIG. 12 is a perspective view of the portable device disclosed in Patent Document 1. FIG. A mobile device 100 illustrated in FIG. 12 is a foldable mobile phone that can overlap an upper housing 101 with a lower housing 102. Hereinafter, the waterproof structure of the upper housing 101 will be described. 13 is an exploded perspective view of the upper housing 101 of the portable device 100 shown in FIG. As shown in FIG. 13, the upper housing 101 includes a housing cover 111 and a housing case 112. A rubber packing member 103 is sandwiched between the housing cover 111 and the housing case 112. FIG. 14 is a plan view of the packing member 103. As shown in FIG. 14, the packing member 103 is formed in a frame shape.

図１５は、図１４に示すパッキング部材１０３を上部筐体１０１に取り付ける前の状態を示す断面図である。図１６は、図１４に示すパッキング部材１０３を上部筐体１０１に取り付けた後の状態を示す断面図である。図１５および図１６は、図１３に示す上部筐体１０１を図１２に示す切断線Ａ−Ａに沿って切断した断面図である。図１７は、図１５に示す領域Ｓ１の拡大図である。図１８は、図１６に示す領域Ｓ２の拡大図である。   FIG. 15 is a cross-sectional view showing a state before the packing member 103 shown in FIG. 14 is attached to the upper housing 101. FIG. 16 is a cross-sectional view illustrating a state after the packing member 103 illustrated in FIG. 14 is attached to the upper housing 101. 15 and 16 are cross-sectional views of the upper housing 101 shown in FIG. 13 cut along the cutting line AA shown in FIG. FIG. 17 is an enlarged view of the region S1 shown in FIG. FIG. 18 is an enlarged view of the region S2 shown in FIG.

筐体ケース１１２の周縁部には溝１１２ａが形成されている（図１５、図１７参照）。溝１１２ａには、パッキング部材１０３が嵌め込まれる（図１６、図１８参照）。筐体カバー１１１における、溝１１２ａに対向する位置には、リブ１１１ａが形成されている。リブ１１１ａが、パッキング部材１０３を押し潰すことによって、パッキング部材１０３は圧縮して溝１１２ａの内部空間を満たす（図１８参照）。これにより、筐体カバー１１１と筐体ケース１１２との間に形成された内部空間１０４が密閉されるので、内部空間１０４を防水することが可能となる（図１６参照）。   A groove 112a is formed on the peripheral edge of the housing case 112 (see FIGS. 15 and 17). The packing member 103 is fitted into the groove 112a (see FIGS. 16 and 18). Ribs 111a are formed in the housing cover 111 at positions facing the grooves 112a. When the rib 111a crushes the packing member 103, the packing member 103 is compressed to fill the internal space of the groove 112a (see FIG. 18). Thereby, since the internal space 104 formed between the housing cover 111 and the housing case 112 is sealed, the internal space 104 can be waterproofed (see FIG. 16).

（実施形態１）
図１は、本発明の携帯機器の一実施形態を示す分解斜視図である。図１に示す携帯機器１０は、筐体１２に筐体１１を重ねることが可能な折り畳み式の携帯電話機である。以下、筐体１１の防水構造について説明する。 (Embodiment 1)
FIG. 1 is an exploded perspective view showing an embodiment of a portable device of the present invention. A mobile device 10 illustrated in FIG. 1 is a foldable mobile phone that can overlap a housing 11 with a housing 12. Hereinafter, the waterproof structure of the housing 11 will be described.

図１に示すように、筐体１１は、カバー１と、カバー１に対向配置したケース２とを有する。カバー１とケース２との間には、パッキング部材３が設けられている。以下、パッキング部材３について詳しく説明する。   As shown in FIG. 1, the housing 11 includes a cover 1 and a case 2 disposed to face the cover 1. A packing member 3 is provided between the cover 1 and the case 2. Hereinafter, the packing member 3 will be described in detail.

図２は、パッキング部材３の平面図である。図３は、図２に示すパッキング部材３を筐体１１に取り付ける前の状態を示す断面図である。図４は、図２に示すパッキング部材３を筐体１１に取り付けた後の状態を示す断面図である。図５は、図３に示す領域Ｒ１の拡大図である。図６は、図４に示す領域Ｒ２の拡大図である。   FIG. 2 is a plan view of the packing member 3. FIG. 3 is a cross-sectional view showing a state before the packing member 3 shown in FIG. 2 is attached to the housing 11. 4 is a cross-sectional view showing a state after the packing member 3 shown in FIG. FIG. 5 is an enlarged view of the region R1 shown in FIG. FIG. 6 is an enlarged view of the region R2 shown in FIG.

図２に示すように、パッキング部材３は枠状に形成されている。図３および図４に示すように、パッキング部材３は、枠状のゴム部材３１と、枠状の補強部材３２と、を有する。ゴム部材３１および補強部材３２は、インサート成形により一体に成形されている。   As shown in FIG. 2, the packing member 3 is formed in a frame shape. As shown in FIGS. 3 and 4, the packing member 3 includes a frame-shaped rubber member 31 and a frame-shaped reinforcing member 32. The rubber member 31 and the reinforcing member 32 are integrally formed by insert molding.

補強部材３２は、ゴム部材３１よりも剛性の高い材料、例えば、樹脂、あるいはゴム部材３１よりも硬度の高い硬質ゴムで枠状に成形されている。成形された補強部材３２は、ゴム部材３１を成形するための金型に組み込まれる。そして、ゴム部材３１が、インサート成形によって、補強部材３２に挟み込まれるように成形される。本実施形態では、ゴム部材３１は、その両端が突起状であり、かつ補強部材３２から露出するように成形される（図５参照）。   The reinforcing member 32 is formed into a frame shape from a material having higher rigidity than the rubber member 31, for example, resin or hard rubber having higher hardness than the rubber member 31. The molded reinforcing member 32 is incorporated in a mold for molding the rubber member 31. And the rubber member 31 is shape | molded so that it may be pinched | interposed into the reinforcement member 32 by insert molding. In the present embodiment, the rubber member 31 is shaped so that both ends thereof are protruding and exposed from the reinforcing member 32 (see FIG. 5).

上記のように成形されたパッキング部材３は、カバー１の内面１ａとケース２の内面２ａとの間に取り付けられる。このとき、補強部材３２がゴム部材３１を保持しているのでゴム部材３１の姿勢が安定する。ゴム部材３１は、カバー１の内面１ａおよびケース２の内面２ａ間で押し潰されることによって、その両端がカバー１の内面１ａおよびケース２の内面２ａに密着するように圧縮変形する（図６参照）。これにより、カバー１の内面１ａとケース２の内面２ａの間に形成された内部空間６が密閉される（図４参照）。よって、カバー１とケース２の隙間５（図６参照）から内部空間６への浸水を防ぐことが可能となる。   The packing member 3 molded as described above is attached between the inner surface 1 a of the cover 1 and the inner surface 2 a of the case 2. At this time, since the reinforcing member 32 holds the rubber member 31, the posture of the rubber member 31 is stabilized. When the rubber member 31 is crushed between the inner surface 1a of the cover 1 and the inner surface 2a of the case 2, the rubber member 31 is compressed and deformed so that both ends thereof are in close contact with the inner surface 1a of the cover 1 and the inner surface 2a of the case 2 (see FIG. 6). ). Thereby, the internal space 6 formed between the inner surface 1a of the cover 1 and the inner surface 2a of the case 2 is sealed (see FIG. 4). Therefore, it is possible to prevent water from entering the internal space 6 from the gap 5 (see FIG. 6) between the cover 1 and the case 2.

上述したように本実施形態の携帯機器１０では、パッキング部材３が、枠状のゴム部材３１と、ゴム部材３１よりも剛性の高い枠状の補強部材３２とを一体に成形した構造になっている。これにより、筐体１１を組み立てるときに、図１２に示した携帯機器１００のようにパッキング部材１０３を筐体ケース１１２の溝１１２ａに嵌め込む作業が不要になる。そのため、パッキング部材３（ゴム部材３１）のねじれを防止することが可能となる。   As described above, in the portable device 10 according to the present embodiment, the packing member 3 has a structure in which the frame-shaped rubber member 31 and the frame-shaped reinforcing member 32 having higher rigidity than the rubber member 31 are integrally formed. Yes. Thereby, when the housing 11 is assembled, the operation of fitting the packing member 103 into the groove 112a of the housing case 112 as in the portable device 100 shown in FIG. Therefore, it is possible to prevent the packing member 3 (rubber member 31) from being twisted.

さらに、ゴム部材３１と補強部材３２とを一体化したパッキング部材３は、筐体ケース１１２の溝１１２ａへの嵌め込み作業を必要とするパッキング部材１０３に比べ、筐体１１への取り付け作業が簡易になる。そのため、パッキング部材３の取り付けに要する時間を短縮することが可能になる。   Further, the packing member 3 in which the rubber member 31 and the reinforcing member 32 are integrated is easier to attach to the housing 11 than the packing member 103 that requires the housing case 112 to be fitted into the groove 112a. Become. Therefore, it is possible to shorten the time required for attaching the packing member 3.

さらに、ゴム部材３１だけでなく補強部材３２も外力に対して変形可能な柔軟性を備えていると、落下衝撃を吸収できるので、衝撃に対する信頼性を確保することが可能になる。加えて、補強部材３２が、カバー１およびケース２に押し潰されたときに筐体１１の形状に追従して変形することによって、ゴム部材３１のねじれを防止するとともに、防水性能を高めることが可能となる。   Furthermore, if not only the rubber member 31 but also the reinforcing member 32 is provided with a flexibility that can be deformed with respect to an external force, a drop impact can be absorbed, and thus it is possible to ensure reliability against the impact. In addition, when the reinforcing member 32 is crushed by the cover 1 and the case 2, the rubber member 31 is prevented from being twisted by being deformed following the shape of the housing 11, and the waterproof performance is improved. It becomes possible.

本実施形態では、ゴム部材３１に異物が付着しにくくするために、ゴム部材３１の表面に微細な凹凸が形成されていてもよい。防水用のゴム部材に施す防汚手段としては成形後のゴム部材の表面にフッ素塗料を塗布することが一般的であるが、成形時に凹凸を形成することによってコストダウンを図ることが可能となる。   In the present embodiment, in order to make it difficult for foreign matter to adhere to the rubber member 31, fine irregularities may be formed on the surface of the rubber member 31. As an antifouling means applied to a rubber member for waterproofing, it is common to apply a fluorine paint on the surface of the rubber member after molding, but it becomes possible to reduce costs by forming irregularities during molding. .

（実施形態２）
本実施形態の携帯機器について説明する。以下、上述した実施形態１の携帯機器１０と異なる部分を中心に説明する。 (Embodiment 2)
The portable device of this embodiment will be described. Hereinafter, a description will be given focusing on the differences from the mobile device 10 of the first embodiment described above.

本実施形態の携帯機器は、パッキング部材の構造が実施形態１の携帯機器１０と異なる。図７は、本実施形態の携帯機器に取り付けられたパッキング部材の平面図である。図８は、図７に示すパッキング部材４を筐体１１に取り付ける前の状態を示す断面図である。図９は、図７に示すパッキング部材４を筐体１１に取り付けた後の状態を示す断面図である。図１０は、図８に示す領域Ｒ３の拡大図である。図１１は、図９に示す領域Ｒ４の拡大図である。   The portable device of the present embodiment is different from the portable device 10 of the first embodiment in the structure of the packing member. FIG. 7 is a plan view of the packing member attached to the portable device of the present embodiment. FIG. 8 is a cross-sectional view showing a state before the packing member 4 shown in FIG. FIG. 9 is a cross-sectional view showing a state after the packing member 4 shown in FIG. FIG. 10 is an enlarged view of the region R3 shown in FIG. FIG. 11 is an enlarged view of a region R4 shown in FIG.

図８および図９に示すように、パッキング部材４は、ゴム部材４１と、補強部材４２と、を有する。ゴム部材４１と補強部材４２とは、パッキング部材３と同様にインサート成形によって一体に成形されている。筐体１１に取り付けられる前のゴム部材４１は、図８に示すように、その一端が突起状に成形されている。ゴム部材４１の表面には、ゴム部材３１と同様に、異物の付着を防ぐための微細な凹凸が形成されていてもよい。補強部材４２は、ゴム部材４１よりも剛性の高い材料、例えば、樹脂、あるいはゴム部材４１よりも硬度の高い硬質ゴムで構成されている。   As shown in FIGS. 8 and 9, the packing member 4 includes a rubber member 41 and a reinforcing member 42. The rubber member 41 and the reinforcing member 42 are integrally formed by insert molding similarly to the packing member 3. As shown in FIG. 8, the rubber member 41 before being attached to the housing 11 has one end formed into a protruding shape. On the surface of the rubber member 41, similarly to the rubber member 31, fine unevenness for preventing adhesion of foreign matters may be formed. The reinforcing member 42 is made of a material having higher rigidity than the rubber member 41, for example, resin, or hard rubber having higher hardness than the rubber member 41.

実施形態１のパッキング部材３は、補強部材３２が、ゴム部材３１の両端を露出させるようにゴム部材３１を保持した構造であった。一方、本実施形態のパッキング部材４は、補強部材４２にゴム部材４１を重ねた構造を有している。   The packing member 3 of the first embodiment has a structure in which the reinforcing member 32 holds the rubber member 31 so that both ends of the rubber member 31 are exposed. On the other hand, the packing member 4 of the present embodiment has a structure in which a rubber member 41 is stacked on a reinforcing member 42.

上記のように成形されたパッキング部材４は、カバー１の内面１ａとケース２の内面２ａとの間に取り付けられ、押し潰される。すると、ゴム部材４１は、カバー１の内面１ａに密着するように圧縮変形し、補強部材３２は、ケース２の内面２ａに密着する。これにより、カバー１とケース２の間に形成された内部空間６が密閉される（図９参照）。よって、カバー１とケース２の隙間５（図１１参照）から内部空間６への浸水を防ぐことが可能となる。なお、ゴム部材３１がケース２の内面２ａに密着し、補強部材３２がカバー１の内面１ａに密着する構成であってもよい。   The packing member 4 molded as described above is attached between the inner surface 1a of the cover 1 and the inner surface 2a of the case 2 and is crushed. Then, the rubber member 41 is compressed and deformed so as to be in close contact with the inner surface 1 a of the cover 1, and the reinforcing member 32 is in close contact with the inner surface 2 a of the case 2. Thereby, the internal space 6 formed between the cover 1 and the case 2 is sealed (see FIG. 9). Therefore, it is possible to prevent water from entering the internal space 6 from the gap 5 (see FIG. 11) between the cover 1 and the case 2. The rubber member 31 may be in close contact with the inner surface 2a of the case 2 and the reinforcing member 32 may be in close contact with the inner surface 1a of the cover 1.

上述したように本実施形態の携帯機器では、パッキング部材４が、パッキング部材３と同様に、ゴム部材４１と、ゴム部材４１よりも剛性の高い補強部材４２とを一体に成形した構造になっている。これにより、筐体１１を組み立てるときに、図１２に示した携帯機器１００のようにパッキング部材１０３を筐体ケース１１２の溝１１２ａに嵌め込む作業が不要になる。そのため、パッキング部材４（ゴム部材４１）のねじれを防止することが可能となる。特に、パッキング部材４は、補強部材４２にゴム部材４１を重ねた構造を有するので、筐体１１に取り付けたときに、パッキング部材３に比べ姿勢が安定しやすい。そのため、パッキング部材４の位置合わせが容易になる。   As described above, in the portable device of the present embodiment, the packing member 4 has a structure in which the rubber member 41 and the reinforcing member 42 having rigidity higher than that of the rubber member 41 are integrally formed, like the packing member 3. Yes. Thereby, when the housing 11 is assembled, the operation of fitting the packing member 103 into the groove 112a of the housing case 112 as in the portable device 100 shown in FIG. Therefore, it is possible to prevent the packing member 4 (rubber member 41) from being twisted. In particular, since the packing member 4 has a structure in which the rubber member 41 is overlapped on the reinforcing member 42, the posture is more stable than the packing member 3 when attached to the housing 11. Therefore, alignment of the packing member 4 becomes easy.

さらに、ゴム部材４１と補強部材４２とを一体化したパッキング部材４は、パッキング部材３と同様に、パッキング部材１０３に比べ筐体１１に取り付けるのに要する時間を短縮することが可能になる。   Furthermore, the packing member 4 in which the rubber member 41 and the reinforcing member 42 are integrated can shorten the time required to attach to the housing 11 as compared with the packing member 103, similarly to the packing member 3.

上述した実施形態１、２では、本発明を携帯電話機に適用した実施形態について説明した。しかし、本発明は携帯電話機に限定されず、スマートフォン、ゲーム機、タブレットＰＣ（Personal Computer）、ノートＰＣにも適用可能である。   In the first and second embodiments, the embodiment in which the present invention is applied to a mobile phone has been described. However, the present invention is not limited to a mobile phone, and can be applied to a smartphone, a game machine, a tablet PC (Personal Computer), and a notebook PC.
