Description

本発明は、車両用ドアハンドル装置に関し、特に、ユーザーの施錠若しくは解錠の意志を自動認識するための静電容量センサを内蔵した車両用ドアハンドル装置に関するものである。   The present invention relates to a vehicle door handle device, and more particularly, to a vehicle door handle device incorporating a capacitance sensor for automatically recognizing a user's intention to lock or unlock.

車両のユーザーが開扉する意志をもってドアハンドルに接触したことをドアハンドルに設けられた静電容量センサが検知すると、ユーザーが携帯するカードキーと車両に設けられた制御装置との間でＩＤコードの照合が行われ、ＩＤコードの一致を制御装置が確認すると、ドアロックが自動解錠されるように構成された所謂スマートエントリーシステムが既に実用に供されている。   When a capacitance sensor provided on the door handle detects that the vehicle user has contacted the door handle with the intention of opening the door, an ID code is generated between a card key carried by the user and a control device provided on the vehicle. When the control device confirms that the ID code matches, a so-called smart entry system configured to automatically unlock the door lock has already been put into practical use.

このスマートエントリーシステムにおけるドアハンドル装置として、ユーザーの開扉操作力を受け止めるグリップ部に静電容量の変化を検知する回路基板を内蔵させ、グリップ部の内側にユーザーが接触すると静電容量センサが作動し、グリップ部の外側にユーザーが触れても静電容量センサは作動しないように構成されたものが知られている（特許文献１を参照されたい）。
特開２００３−２２１９４９号公報 As a door handle device in this smart entry system, a circuit board that detects changes in capacitance is built in the grip part that receives the user's opening operation force, and the capacitance sensor is activated when the user touches the inside of the grip part. And what was comprised so that a capacitance sensor may not operate | move even if a user touches the outer side of a grip part is known (refer patent document 1).
Japanese Patent Laid-Open No. 2003-221949

しかるに、ドアハンドルの外観意匠の都合などにより、ドアハンドルの外面に金属部品を設けたり、金属メッキ（蒸着）を部分的に施したりする要望が上がることがある。この場合、金属性部分の一部を静電容量センサに近接させると、この金属性部分が静電容量センサの静電回路の一部を構成してしまい、グリップ部の外側に触れても静電容量センサが作動してしまうことが起こり得る。このことは、ユーザーに開扉する意志がなくても、単にドアハンドルに触れただけでドアロックが解錠してしまうことを意味しており、好ましいことではない。   However, depending on the appearance design of the door handle, there is a case where there is a demand for providing a metal part on the outer surface of the door handle or partially performing metal plating (evaporation). In this case, if a part of the metallic part is brought close to the capacitance sensor, the metallic part forms a part of the electrostatic circuit of the electrostatic capacity sensor, so that even if it touches the outside of the grip part, it is static. It can happen that the capacitance sensor is activated. This means that even if the user does not intend to open the door, the door lock is unlocked simply by touching the door handle, which is not preferable.

このような従来技術の問題点を解消し、外面に金属製部品が設けられたり金属メッキが部分的に施されたりしたドアハンドルの場合でも、静電容量センサが定められた条件のもとに確実に作動するようにするために、本発明の請求項１は、静電容量変化の検知回路（センサユニット８）をグリップ部（１０）に内蔵した車両用ドアハンドル装置（１）において、検知回路にその一部が近接する金属性部分がグリップ部の外側表面に設けられると共に、金属性部分が接地され、ドアハンドル装置に付設される電気部品（照明灯１８）のグランド線（２４）が金属性部分に締結されることを特徴とするものとした。 Even in the case of a door handle in which the metal parts are provided on the outer surface or the metal plating is partially applied to solve the problems of the conventional technology, the capacitance sensor is used under the predetermined conditions. In order to ensure the operation, claim 1 of the present invention provides a vehicle door handle device (1) having a capacitance change detection circuit (sensor unit 8) built in the grip portion (10). A metallic part, part of which is close to the circuit, is provided on the outer surface of the grip part, and the metallic part is grounded, and a ground wire (24) of an electrical component (illumination lamp 18) attached to the door handle device is provided. It is characterized by being fastened to a metallic part .

また本発明の請求項２は、ドアハンドル装置に付設される電気部品（照明灯１８）のグランド線（２４）の中間部が金属性部分に締結されるものとした。 The second aspect of the present invention has assumed that the middle portion of the ground line of the electrical components attached to the door handle device (lamp 18) (24) is fastened to the metallic portion.

このような本発明の請求項１の構成によれば、ユーザーが望まないのにドアロックが解錠されるということがなくなるので、作動信頼性を高める上に効果的である。特に金属性部分をドアハンドルに付設した照明灯などのグランド線を用いて接地することにより、構成を複雑化せずに済む。 According to such a configuration of claim 1 of the present invention, the door lock is not unlocked although the user does not want it, which is effective in improving the operation reliability. In particular, by grounding the metallic part using a ground wire such as an illuminating lamp attached to the door handle, the configuration does not have to be complicated.

以下に添付の図面を参照して本発明について詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

図１〜図３は、本発明が適用されたドアハンドル装置の全体構成を示している。このドアハンドル装置１は、乗用車のサイドドアのアウタパネル２の内側に固定されたハンドルベース３を介してドアアウタパネル２の外面に取り付けられており、車体の前後方向に延在する操作ハンドル４と、操作ハンドル４の後端側に付設されたキーシリンダ５とを備えている。   1 to 3 show an overall configuration of a door handle device to which the present invention is applied.

The hinge portion 11 is pivotally attached to the front end portion of the handle base 3, and the guide portion 12 side tilts so as to protrude sideways from the outer surface of the door outer panel 2, and the door lock is released by this operation. Yes. In addition, since the function and structure regarding the door opening / closing operation of the operation handle 4 are not related to the essence of the present invention, the description is omitted here.

ドアアウタパネル２のグリップ部１０との対向面には、外向きに湾曲したグリップ部１０とドアアウタパネル２との間にユーザーの指先を差し込めるようにするための窪み１３が形成されている。   A recess 13 is formed on the surface of the door outer panel 2 facing the grip portion 10 so that the user's fingertip can be inserted between the grip portion 10 curved outward and the door outer panel 2.

本体部６のグリップ部１０に対応する位置には、図４に示したように、下向きに開放された断面Ｕ字状をなす空所１４がその全長に渡って形成されている。この空所１４の開口面は、下部カバー７で塞がれている。つまり、本体部６と下部カバー７とを互いに接合して中空な外殻が構成されている。   As shown in FIG. 4, a space 14 having a U-shaped cross-section opened downward is formed at a position corresponding to the grip portion 10 of the main body 6 over the entire length thereof. The opening surface of the void 14 is closed by the lower cover 7. In other words, the main body 6 and the lower cover 7 are joined together to form a hollow outer shell.

センサユニット８は、僅かに湾曲した細長い平板状をなしており、複数のリード線１５が長手方向の一端から延出されている。これらのリード線１５の端末は、コネクタ１６に結合することで処理されている。   The sensor unit 8 has an elongated flat plate shape that is slightly curved, and a plurality of lead wires 15 extend from one end in the longitudinal direction. The ends of these lead wires 15 are processed by being connected to the connector 16.

保持部材９は、グリップ部１０に形成された空所１４の内面にその外面が密接するように形成されると共に、上向きに開放した断面Ｕ字状をなす保持溝１７がその全長に渡って形成されている。この保持溝１７は、その深さ寸法並びに幅寸法が、センサユニット８を隙間なく受容できる寸法に定められている。この構造により、グリップ部１０を薄肉にした場合でも、グリップ部１０の十分な強度、剛性を確保することが可能である。   The holding member 9 is formed so that the outer surface thereof is in close contact with the inner surface of the cavity 14 formed in the grip portion 10, and the holding groove 17 having a U-shaped cross section opened upward is formed over the entire length thereof. Has been. The holding groove 17 has a depth dimension and a width dimension such that the sensor unit 8 can be received without a gap. With this structure, even when the grip portion 10 is thin, sufficient strength and rigidity of the grip portion 10 can be ensured.

保持部材９並びに本体部６におけるグリップ部１０の前端側には、図５に示したように、グリップ部１０と対向するアウタパネル２の窪み１３を照光するための照明灯１８の保持部１９・２０が形成されており、保持部材９を本体部６の空所１４内に収納すると、本体部６及び保持部材９の両保持部１９・２０間に挟まれて照明灯１８が固定されるようになっている。照明灯１８の外周面はゴム製のシール部材２１が装着されており、グリップ部１０内への水の浸入を防止すると共に、照明灯１８を振動から保護している。また保持部材９の照明灯保持部１９には矩形孔２２が開設されており、照明灯１８の外面に突設された爪２３が係合して照明灯１８が保持部材９に仮止めされるようになっている。   On the front end side of the grip portion 10 in the holding member 9 and the main body portion 6, as shown in FIG. 5, the holding portions 19 and 20 of the illuminating lamp 18 for illuminating the depression 13 of the outer panel 2 facing the grip portion 10. When the holding member 9 is stored in the space 14 of the main body 6, the illumination lamp 18 is fixed by being sandwiched between the holding portions 19 and 20 of the main body 6 and the holding member 9. It has become. A rubber seal member 21 is attached to the outer peripheral surface of the illuminating lamp 18 to prevent water from entering the grip portion 10 and to protect the illuminating lamp 18 from vibration. A rectangular hole 22 is formed in the illuminating lamp holding portion 19 of the holding member 9, and a claw 23 protruding from the outer surface of the illuminating lamp 18 is engaged so that the illuminating lamp 18 is temporarily fixed to the holding member 9. It is like that.

照明灯１８のリード線のグランド線２４は途中で分断され、その各端末に圧着端子２５が固着されている。この圧着端子２５は、図６に示したように、ゴム製のシール部材２６が被着された上で、本体部６のヒンジ部１１近傍に下部カバー７の前端部７ａと共締めで固定されている。これにより、下部カバー７の金属メッキ層が接地するので、金属性の部分にユーザーが接触しても静電容量が変化せず、誤作動することがない。またこのように照明灯１８のグランド線２４を利用して操作ハンドル４の金属性部分を接地することができるので、操作ハンドル４の金属性部分のみを接地させるために専用の接地線を引き回す必要がない。   The ground wire 24 of the lead wire of the illuminating lamp 18 is divided in the middle, and a crimp terminal 25 is fixed to each terminal. As shown in FIG. 6, the crimp terminal 25 is fixed by fastening together with the front end portion 7 a of the lower cover 7 in the vicinity of the hinge portion 11 of the main body portion 6 after the rubber seal member 26 is attached. ing. Thereby, since the metal plating layer of the lower cover 7 is grounded, even if the user touches the metallic portion, the capacitance does not change and no malfunction occurs. Further, since the metallic part of the operation handle 4 can be grounded using the ground line 24 of the illuminating lamp 18 in this way, it is necessary to draw a dedicated grounding line in order to ground only the metallic part of the operating handle 4. There is no.

センサユニット８を受容した保持部材９を本体部６の空所１４内に収納し、空所１４の開口を下部カバー７で塞ぎ、要所を例えばビス止めすることにより、操作ハンドル４のサブアセンブリが完成する。   The holding member 9 that has received the sensor unit 8 is housed in the space 14 of the main body 6, the opening of the space 14 is closed with the lower cover 7, and the important part is screwed, for example, so that the sub-assembly of the operation handle 4 Is completed.
