以下、本発明の実施形態として、図１に示すようにケース本体部１１０とケース端部１２０とを有する車両用電子キー１００の例を説明する。   Hereinafter, as an embodiment of the present invention, an example of a vehicle electronic key 100 having a case main body 110 and a case end 120 as shown in FIG. 1 will be described.

ケース本体部１１０は、ケース本体下部１１１とケース本体上部１１２とが重ね合わされて構成されている。ケース本体部１１０の内部には、例えば車両のドアの解錠やエンジンの始動などをリモートコントロールするための電波を発する図示しない電子回路が収容されている。ケース端部１２０は、上記ケース本体部１１０の端部に設けられ、キーホルダやキーリング等のキー保持部材が取り付けられる貫通孔１２１ａ、および貫通孔１２２ｂが形成されている。   The case body 110 is configured by overlapping a case body lower part 111 and a case body upper part 112. Inside the case main body 110, for example, an electronic circuit (not shown) that emits radio waves for remotely controlling vehicle door unlocking, engine starting, and the like is accommodated. The case end 120 is provided at the end of the case body 110, and is formed with a through hole 121a and a through hole 122b to which a key holding member such as a key holder or a key ring is attached.

上記ケース端部１２０は、より詳しくは、図２〜図４に示すように、端部部材１２１と、ベース部材１２２とを有している。   More specifically, the case end 120 includes an end member 121 and a base member 122, as shown in FIGS.

端部部材１２１には、上記貫通孔１２１ａに垂直な方向、すなわちケース本体部１１０側から上記貫通孔１２１ａに連通し、上記ケース本体部１１０側に開口する溝部１２１ｂが形成されている。溝部１２１ｂの周囲には、後述するベース部材１２２のフランジ部１２２ｃが嵌まり込むフランジ受部１２１ｃが設けられている。   The end member 121 is formed with a groove 121b that communicates with the through hole 121a in a direction perpendicular to the through hole 121a, that is, from the case main body 110 side and opens to the case main body 110 side. Around the groove portion 121b, a flange receiving portion 121c into which a flange portion 122c of a base member 122 described later is fitted is provided.

一方、ベース部材１２２は、上記端部部材１２１の溝部１２１ｂにケース本体部１１０側から挿入される挿入部１２２ａと、上記端部部材１２１のフランジ受部１２１ｃに嵌まり込むフランジ部１２２ｃとを有している。挿入部１２２ａには、端部部材１２１の貫通孔１２１ａに連通する貫通孔１２２ｂが形成されている。より詳しくは、例えば図４に示すように、貫通孔１２１ａと貫通孔１２２ｂとによってケース端部１２０の貫通孔全体が形成されるようになっている。すなわち、端部部材１２１は、ベース部材１２２の貫通孔１２２ｂに連通する貫通孔１２１ａを有し、ベース部材１２２の貫通孔１２２ｂの内周部の少なくとも一部が露出するようにベース部材１２２を覆うようになっている。また、貫通孔全体の少なくとも一部に、内周部材としてのベース部材１２２が設けられている。   On the other hand, the base member 122 has an insertion portion 122a that is inserted into the groove portion 121b of the end member 121 from the case main body 110 side, and a flange portion 122c that is fitted into the flange receiving portion 121c of the end member 121. is doing. A through hole 122b communicating with the through hole 121a of the end member 121 is formed in the insertion part 122a. More specifically, as shown in FIG. 4, for example, the entire through hole of the case end 120 is formed by the through hole 121a and the through hole 122b. That is, the end member 121 has a through hole 121a communicating with the through hole 122b of the base member 122, and covers the base member 122 so that at least a part of the inner peripheral portion of the through hole 122b of the base member 122 is exposed. It is like that. Further, a base member 122 as an inner peripheral member is provided in at least a part of the entire through hole.

上記端部部材１２１は、例えば比較的安価で成型しやすいＡＢＳ樹脂を用いて形成されている。一方、ベース部材１２２は、端部部材１２１よりも硬質の樹脂、または高い強度および高い硬度の少なくとも一方を有する樹脂、例えばガラス繊維入りのＰＢＴ樹脂などの強化樹脂を用いて形成されている。すなわち、貫通孔全体の内周部の少なくとも一部に、端部部材１２１を形成する樹脂よりも硬質の樹脂や高強度の樹脂から成るベース部材１２２が設けられている。   The end member 121 is formed using, for example, an ABS resin that is relatively inexpensive and easy to mold. On the other hand, the base member 122 is formed using a resin harder than the end member 121 or a resin having at least one of high strength and high hardness, for example, a reinforced resin such as PBT resin containing glass fiber. That is, the base member 122 made of a resin harder than the resin forming the end member 121 or a resin having a higher strength is provided on at least a part of the inner peripheral portion of the entire through hole.

ベース部材１２２の上記フランジ部１２２ｃの周囲、すなわち端部部材１２１とベース部材１２２との当接面のうち、上記ベース部材１２２を上記端部部材１２１に挿入する方向に垂直な方向に互いに当接する当接面には、必須ではないが複数の凸状部１２２ｄが形成され、端部部材１２１のフランジ受部１２１ｃに嵌まり込んだときにがたつきを抑制し、または小さく抑えることができるようになっている。なお、上記のような凸部は端部部材１２１側に設けられてもよい。フランジ部１２２ｃにはネジ１２３が挿通されるネジ穴１２２ｅが形成され、上記ネジ１２３が端部部材１２１に形成された雌ネジ１２１ｄに螺合することによって、端部部材１２１がベース部材１２２に固定されるようになっている。なお、上記固定は接着剤によって行われるなどしてもよい。上記ベース部材１２２には、また、フランジ部１２２ｃに対して挿入部１２２ａと反対側に係止部１２２ｆが形成され、後述するようにベース部材１２２をケース本体部１１０に固定し得るようになっている。上記係止部１２２ｆの形状は、特に限定されないが、例えば図４に示すように断面Ｔ字形状に形成されている。なお、端部部材１２１に同様の係止部等が形成されて、端部部材１２１が直接ケース本体部１１０に固定し得るようにされてもよい。   Around the flange portion 122 c of the base member 122, that is, among the contact surfaces between the end member 121 and the base member 122, they are in contact with each other in a direction perpendicular to the direction in which the base member 122 is inserted into the end member 121. Although not necessarily essential, a plurality of convex portions 122d are formed on the abutment surface so that rattling can be suppressed or reduced when fitted into the flange receiving portion 121c of the end member 121. It has become. The convex portion as described above may be provided on the end member 121 side. A screw hole 122e through which a screw 123 is inserted is formed in the flange portion 122c, and the end member 121 is fixed to the base member 122 by screwing the screw 123 into a female screw 121d formed in the end member 121. It has come to be. The fixing may be performed with an adhesive. The base member 122 is also provided with a locking portion 122f opposite to the insertion portion 122a with respect to the flange portion 122c, so that the base member 122 can be fixed to the case main body 110 as will be described later. Yes. Although the shape of the said latching | locking part 122f is not specifically limited, For example, as shown in FIG. 4, it is formed in the cross-sectional T shape. In addition, the same latching | locking part etc. may be formed in the edge part member 121, and the edge part member 121 may be directly fixed to the case main body part 110. FIG.

ケース本体下部１１１およびケース本体上部１１２は、それぞれ、底壁１１１ａ・１１２ａおよび側壁１１１ｂ・１１２ｂを有し、内部に電子回路が収容される空間が形成されるようになっている。側壁１１１ｂ・１１２ｂにおける端部側部分には、凹部１１１ｃ・１１２ｃが形成され、ベース部材１２２の係止部１２２ｆが係合することにより、ベース部材１２２および端部部材１２１がケース本体部１１０に固定されるようになっている。   The case main body lower part 111 and the case main body upper part 112 have bottom walls 111a and 112a and side walls 111b and 112b, respectively, and spaces for accommodating electronic circuits are formed therein. Concave portions 111c and 112c are formed in the end portions of the side walls 111b and 112b, and the base member 122 and the end member 121 are fixed to the case main body 110 by engaging the engaging portion 122f of the base member 122. It has come to be.


ここで、端部部材１２１やベース部材１２２は、車両用電子キー１００の長手方向の軸に対して線対称な形状を有していれば、上記軸に対して１８０度回転させても互いに、またはケース本体部１１０に組み付け可能にできる。一方、非対称な部分を設けることによって、回転位置を一意に定めることができる。
Here, as long as the end member 121 and the base member 122 have a line-symmetric shape with respect to the longitudinal axis of the vehicle electronic key 100, the end member 121 and the base member 122 are mutually rotated even when rotated 180 degrees with respect to the axis. Alternatively, it can be assembled to the case main body 110. On the other hand, the rotational position can be uniquely determined by providing the asymmetric part.

上記のように、貫通孔１２１ａの内周部よりも貫通孔１２２ｂの内周部の方が突出した部分を有するように設定されることによって、キーホルダ等との接触が主に貫通孔１２２ｂの内周部によって行われる。それゆえ、端部部材１２１よりも硬質の樹脂、または高い強度および高い硬度の少なくとも一方を有する樹脂でベース部材１２２を形成することによって、端部部材１２１の傷付きを防止したり低減したりすることが容易にできる。また、キーホルダ等から作用する力が主に貫通孔１２２ｂの内周部によって受けられ、ケース端部１２０が破損しにくいようにすることも容易にできる。しかも、ベース部材１２２として塗装が困難な樹脂を用いる場合でも、端部部材１２１として塗装が容易な樹脂を用いることによって外観の自由度を高めることが容易にできる。なお、貫通孔１２２ｂの内周部は、必ずしも、図４に示したように貫通孔１２１ａの内周部よりも突出させるのに限らず、面一や貫通孔１２１ａの内周部の方が突出するように設定される場合でも、各部の撓み等に応じて実際上、キーホルダ等から作用する力が主に貫通孔１２２ｂの内周部によって受けられるようにしてケース端部１２０が破損しにくいようにしてもよい。   As described above, by setting the inner peripheral portion of the through hole 122b to protrude from the inner peripheral portion of the through hole 121a, the contact with the key holder or the like is mainly inside the through hole 122b. Performed by the perimeter. Therefore, the base member 122 is formed of a resin harder than the end member 121 or a resin having at least one of high strength and high hardness, thereby preventing or reducing damage to the end member 121. Can be easily done. Further, the force acting from the key holder or the like is mainly received by the inner peripheral portion of the through hole 122b, so that the case end portion 120 can be easily prevented from being damaged. Moreover, even when a resin that is difficult to paint is used as the base member 122, the degree of freedom in appearance can be easily increased by using a resin that is easy to paint as the end member 121. Note that the inner peripheral portion of the through hole 122b is not necessarily protruded from the inner peripheral portion of the through hole 121a as shown in FIG. 4, but the inner peripheral portion of the through hole 121a is flush with the flush surface. Even when set to be so that the case end 120 is not easily damaged by allowing the force acting from the key holder or the like to be received mainly by the inner peripheral portion of the through-hole 122b in accordance with the bending of each portion. It may be.

（変形例）
貫通孔付近の傷やひび割れなどに起因して貫通孔が破断したりするのを防止するためには、図５、図６に示すように、端部部材１２１の貫通孔１２１ａに内周部材１２４を挿入するようにしてもよい。同図の例では、図２、図３に示したようなベース部材１２２の係止部１２２ｆに代えて、端部部材１２１に形成された係止部１２１ｅによって、ケース端部１２０をケース本体部１１０に固定し得るようになっている。この場合には、キーホルダ等が主に接触するのは内周部材１２４の貫通孔１２４ａの内周面なので、内周部材１２４として、端部部材１２１よりも硬質の樹脂を適用することによって、貫通孔付近の傷やひび割れなどに起因して貫通孔が破断したりするのを防止することが容易にできる。 (Modification)
In order to prevent the through hole from being broken due to scratches or cracks in the vicinity of the through hole, as shown in FIGS. 5 and 6, the inner peripheral member 124 is inserted into the through hole 121 a of the end member 121. May be inserted. In the example of the figure, the case end portion 120 is replaced with the case main body portion by a locking portion 121e formed on the end member 121 instead of the locking portion 122f of the base member 122 as shown in FIGS. 110 can be fixed. In this case, the key holder or the like is mainly in contact with the inner peripheral surface of the through hole 124a of the inner peripheral member 124. Therefore, by applying a resin that is harder than the end member 121 as the inner peripheral member 124, the penetration can be achieved. It is easy to prevent the through hole from being broken due to scratches or cracks in the vicinity of the hole.

（その他の事項）
上記のように端部部材１２１とベース部材１２２との２つの部材を組み合わせて用いる場合には、例えば一方が損傷した場合などに一方だけ交換可能にすることができる。 (Other matters)
When the two members of the end member 121 and the base member 122 are used in combination as described above, only one of them can be exchanged when, for example, one of them is damaged.

また、強度や硬度をある程度確保しつつ、金属製の強度部材を用いる場合に比べて軽量化や形状の自由度向上を図ることができる。   In addition, while securing strength and hardness to some extent, it is possible to reduce the weight and improve the degree of freedom of shape as compared with the case where a metal strength member is used.

一般に、金属プレートにプレス加工によって貫通孔を形成する場合には例えば２．６ｍｍ以上の金属プレートを用いることは困難である一方、端部部材１２１に形成される溝部１２１ｂの幅を２．６ｍｍ以下にすることは金型を形成することが困難である。これに対して、上記のように強度や硬度が異ならせた樹脂製の端部部材１２１およびベース部材１２２を用いることによって、貫通孔を形成することが容易で、かつ、ベース部材１２２の挿入溝を形成することも容易にすることができる。   In general, when a through-hole is formed in a metal plate by pressing, it is difficult to use a metal plate of 2.6 mm or more, for example, while the width of the groove 121b formed in the end member 121 is 2.6 mm or less. It is difficult to form a mold. On the other hand, by using the resin end member 121 and the base member 122 having different strength and hardness as described above, it is easy to form a through hole, and the insertion groove of the base member 122 is used. Can also be formed easily.
