Description

本発明は、乗員の指先を検知して解錠操作を行なう車両用ドアハンドル装置に関する。   The present invention relates to a vehicle door handle device that detects an occupant's fingertip and performs an unlocking operation.

この種の従来の車両用ドアハンドル装置としては、特許文献１に開示されたものがある。この車両用ドアハンドル装置１００は、図４に示すように、アウトサイドドアパネル１０１の外側に装着されるドアハンドル１０２と、このドアハンドル１０２に内蔵され、周辺の電界の変化を検知する静電容量検知センサ１０３とを備えている。ドアハンドル１０２はわずかに外側に湾曲するとともに、アウトサイドドアパネル１０１のドアハンドル１０２との対向面には、乗員の指先を受け入れるための凹部１０４が形成されており、この凹部１０４を照らす照明灯１０５が設けられている。また、ドアハンドル１０２は、絶縁性の合成樹脂材からなるグリップ部材１０６と、表面に金属メッキ層が設けられ、グリップ部材１０６の下部開口を覆う下部カバー（図示せず）とから構成されている。静電容量検知センサ１０３及び照明灯１０５から複数のリード線１０７が延出し、これら複数のリード線１０７のうち照明灯１０５のグランド線１０７ａが、途中で下部カバー表面の金属メッキ層に接続されている。   A conventional vehicle door handle device of this type is disclosed in Patent Document 1. As shown in FIG. 4, the vehicle door handle device 100 includes a door handle 102 mounted on the outside of the outside door panel 101, and a capacitance that is built in the door handle 102 and detects a change in a surrounding electric field. And a detection sensor 103. The door handle 102 is slightly curved outward, and a concave portion 104 for receiving a fingertip of an occupant is formed on a surface of the outside door panel 101 facing the door handle 102, and an illumination lamp 105 that illuminates the concave portion 104. Is provided. The door handle 102 includes a grip member 106 made of an insulating synthetic resin material, and a lower cover (not shown) that has a metal plating layer on its surface and covers the lower opening of the grip member 106. . A plurality of lead wires 107 extend from the capacitance detection sensor 103 and the illuminating lamp 105, and the ground wire 107a of the illuminating lamp 105 among the plurality of lead wires 107 is connected to the metal plating layer on the surface of the lower cover. Yes.

上記構成において、ドアハンドル１０２のグリップ部材１０６が絶縁性の合成樹脂材から構成され、グリップ部材１０６に内蔵した静電容量検知センサ１０３の正電極及び負電極間で電界が形成されるので、ドアハンドル１０２を把持しようとして乗員の指先が前記電界を遮り電界強度が変化すると、静電容量検知センサ１０３の静電容量が変化してドア解錠操作を行なう。また、ドアハンドル１０２の下部カバー表面の金属メッキ層が接地しており、該金属メッキ層に乗員が接触しても静電容量が変化しないので、静電容量検知センサ１０３が誤作動せず、所定の条件のもとに確実に作動することができる。   In the above configuration, the grip member 106 of the door handle 102 is made of an insulating synthetic resin material, and an electric field is formed between the positive electrode and the negative electrode of the capacitance detection sensor 103 built in the grip member 106. When the occupant's fingertip blocks the electric field and the electric field strength changes while trying to grip the handle 102, the electrostatic capacity of the electrostatic capacity detection sensor 103 changes and the door unlocking operation is performed. In addition, since the metal plating layer on the lower cover surface of the door handle 102 is grounded, and the capacitance does not change even if an occupant contacts the metal plating layer, the capacitance detection sensor 103 does not malfunction, It can operate reliably under predetermined conditions.

しかしながら、従来の車両用ドアハンドル装置１００では、ハンドル本体１０２のグリップ部材１０６を絶縁性の合成樹脂材から構成したので、グリップ部材１０６に内蔵した静電容量検知センサ１０３の正電極及び負電極間で電界を十分に形成することができるが、ハンドル本体１０２のグリップ部材１０６表面に金属メッキ層を設けた場合、該金属メッキ層が上記電界を乱すとともに、金属メッキ層を上記電界が通過する際に電界が弱まるため、静電容量検知センサの感度が低下して人体と他の物質との識別が困難になるという問題がある。   However, in the conventional vehicle door handle device 100, since the grip member 106 of the handle body 102 is made of an insulating synthetic resin material, between the positive electrode and the negative electrode of the capacitance detection sensor 103 built in the grip member 106. However, when a metal plating layer is provided on the surface of the grip member 106 of the handle body 102, the metal plating layer disturbs the electric field and the electric field passes through the metal plating layer. In addition, since the electric field is weakened, there is a problem that the sensitivity of the capacitance detection sensor is lowered and it is difficult to distinguish the human body from other substances.

なお、他の静電容量検知センサとして、正電極のみを実装するとともに、負電極をセンサ本体の電源ＧＮＤとし、センサＧＮＤをアウトサイドドアパネルへ接続することにより、アウトサイドドアパネル（負電極）及び正電極間の電界の変化を検出するものもある。この場合、アウトサイドドアパネルが車両毎に異なるため、共通のグリップ部材を用いたときでも車両毎に静電容量検知センサの感度調整が必要になり、そのための手間や費用が掛かるという問題がある。一方、前記感度調整を行なう代わりに、静電容量検知センサの感度を上げたとき、車両毎に人体と他の物質との識別差が生じるという問題がある。   As another capacitance detection sensor, only the positive electrode is mounted, the negative electrode is used as the power supply GND of the sensor body, and the sensor GND is connected to the outside door panel, so that the outside door panel (negative electrode) and the positive electrode are connected. Some detect changes in the electric field between the electrodes. In this case, since the outside door panel is different for each vehicle, it is necessary to adjust the sensitivity of the capacitance detection sensor for each vehicle even when a common grip member is used. On the other hand, when the sensitivity of the capacitance detection sensor is increased instead of performing the sensitivity adjustment, there is a problem that a discrimination difference between the human body and other substances occurs for each vehicle.

そこで、本発明は、グリップ部材表面に金属メッキ層を設けた場合であっても人体と他の物質とを識別して確実に検知でき、安定した検知感度が得られるとともに、車両毎の感度調整を要せずにグリップ部材の共用化を図ることができる車両用ドアハンドル装置を提供することを目的とする。   Therefore, the present invention can identify and reliably detect the human body and other substances even when a metal plating layer is provided on the surface of the grip member, and can provide stable detection sensitivity and sensitivity adjustment for each vehicle. An object of the present invention is to provide a vehicle door handle device capable of sharing a grip member without requiring the above.

上記目的を達成する請求項１の発明は、略弓形状を有し、一端を揺動自在に支持されたハンドル本体と、該ハンドル本体内に配設され、正電極及び負電極を有する静電容量センサとを備えた車両用ドアハンドル装置であって、前記ハンドル本体は、表面に導電層を備えたグリップ部材と、絶縁体からなり、該グリップ部材の裏面側に配設されるカバー部材とから構成され、該グリップ部材と該カバー部材との間に形成される収納スペースに前記静電容量センサを収容した状態で、該カバー部材が該収納スペースを閉止するとともに、該静電容量センサの前記正電極及び前記負電極のうちの一方を、該静電容量センサとともに収納スペースに内蔵するとともに、該正電極及び該負電極のうちの他方を、該導電層に電気的に接続したことを特徴とする。   The invention according to claim 1, which achieves the above object, has a handle body having a substantially arcuate shape and supported at one end so as to be swingable, and an electrostatic device disposed in the handle body and having a positive electrode and a negative electrode. A vehicle door handle device including a capacitance sensor, wherein the handle body includes a grip member having a conductive layer on a surface thereof, and a cover member made of an insulator and disposed on a back side of the grip member. The cover member closes the storage space in a state in which the capacitance sensor is stored in a storage space formed between the grip member and the cover member. One of the positive electrode and the negative electrode is built in a storage space together with the capacitance sensor, and the other of the positive electrode and the negative electrode is electrically connected to the conductive layer. Features and That.

請求項２の発明は、請求項１記載の車両用ドアハンドル装置であって、前記グリップ部材は、ドアの裏面側に向かって開口する断面略コ字形状を備え、前記カバー部材は、該グリップ部材のコ字形状部分の内部に配設されることを特徴とする。   The invention according to claim 2 is the vehicle door handle device according to claim 1, wherein the grip member has a substantially U-shaped cross section that opens toward the back side of the door, and the cover member has the grip It is arranged inside the U-shaped part of the member.

請求項１の発明によれば、グリップ部材内の一方の電極とグリップ部材表面の金属メッキ層との間で電界を形成し、乗員の指先が電界を遮ったときに、電界強度が変化したことを静電容量検知センサで検知する。これにより、グリップ部材表面に金属メッキ層を設けた場合であっても、人体と他の物質とを識別して確実に検知でき、安定した検知感度が得られる。また、異なる車両に取り付けた場合でも上記電界の強度に差が発生しないため、車両毎の感度調整を要せずにグリップ部材の共用化を図ることができ、手間や費用を抑制できる。   According to the first aspect of the present invention, an electric field is formed between one electrode in the grip member and the metal plating layer on the surface of the grip member, and the electric field strength is changed when the occupant's fingertip blocks the electric field. Is detected by a capacitance detection sensor. Accordingly, even when a metal plating layer is provided on the surface of the grip member, the human body and other substances can be identified and reliably detected, and stable detection sensitivity can be obtained. In addition, even when attached to different vehicles, there is no difference in the intensity of the electric field, so that the grip member can be shared without requiring sensitivity adjustment for each vehicle, and labor and cost can be reduced.

請求項２の発明によれば、請求項１の発明の効果に加え、カバー部材がグリップ部材のコ字形状部分の内部に配設され、コ字形状の開口端がカバー部材とともに、ドアの裏面側に向かって露出したことによって、静電容量センサの正電極と負電極とが裏面側に面して隣接配置される。このことによって、静電容量センサの電界が安定し、乗員がハンドル本体の裏面側に指先をかざした際に起きる電界強度の変化をより確実に検出することができる。   According to the invention of claim 2, in addition to the effect of the invention of claim 1, the cover member is disposed inside the U-shaped portion of the grip member, and the U-shaped opening end together with the cover member serves as the back surface of the door. By being exposed toward the side, the positive electrode and the negative electrode of the capacitance sensor are adjacently disposed facing the back surface side. As a result, the electric field of the capacitance sensor is stabilized, and a change in electric field strength that occurs when the occupant holds the fingertip on the back side of the handle body can be detected more reliably.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１〜図３に示すように、本実施形態の車両用ドアハンドル装置１は、車体の前後方向（図１の左右方向）に延びてアウトサイドドアパネル２の外側に装着されるハンドル本体３を備えるとともに、このハンドル本体３に、周辺に形成される電界Ａの変化を検知する静電容量検知センサ４と、この静電容量検知センサ４と一体に設けられる正電極４１と、キーレスエントリーシステム（図示せず）の構成要素であり、乗員が携帯する携帯キー（図示せず）と交信する信号を送受信するＬＦアンテナ５とが内蔵されている。なお、静電容量検知センサ４、正電極４１及びＬＦアンテナ５の各表面はそれぞれ絶縁されている。   As shown in FIGS. 1 to 3, the vehicle door handle device 1 of the present embodiment includes a handle body 3 that extends in the front-rear direction of the vehicle body (the left-right direction in FIG. 1) and is attached to the outside of the outside door panel 2. The electrostatic capacity detection sensor 4 for detecting a change in the electric field A formed in the periphery of the handle body 3, a positive electrode 41 provided integrally with the electrostatic capacity detection sensor 4, and a keyless entry system ( A LF antenna 5 that transmits and receives signals communicated with a portable key (not shown) carried by a passenger is incorporated. Each surface of the capacitance detection sensor 4, the positive electrode 41, and the LF antenna 5 is insulated.

アウトサイドドアパネル２のハンドル本体３との対向面には、乗員の指を受け入れるための凹部２１が形成されている。   A concave portion 21 for receiving an occupant's finger is formed on the surface of the outside door panel 2 facing the handle body 3.

ハンドル本体３は、断面略コ字形状に形成され、アウトサイドドアパネル２に面する裏面側が開口するグリップ部材３１と、断面略コ字形状に形成され、グリップ部材３１の開口端３２に嵌合するカバー部材３３とから構成されており、これらのグリップ部材３１及びカバー部材３３は、互いに組み付けられた状態にて内部に長手方向（図１の左右方向）へ延びる収納スペース３４が形成されている。グリップ部材３１は、全表面に導電層としてクロームメッキ層などの金属メッキ層３５が設けられた合成樹脂材から形成されており、一方、カバー部材３３は、絶縁性の現着樹脂材から形成されている。   The handle body 3 is formed in a substantially U-shaped cross section, and is formed with a grip member 31 that opens on the back side facing the outside door panel 2, and is formed in a substantially U-shaped cross section and is fitted to the opening end 32 of the grip member 31. The grip member 31 and the cover member 33 are formed with a storage space 34 extending in the longitudinal direction (left-right direction in FIG. 1) in the assembled state. The grip member 31 is formed of a synthetic resin material provided with a metal plating layer 35 such as a chrome plating layer as a conductive layer on the entire surface, while the cover member 33 is formed of an insulating current resin material. ing.

静電容量検知センサ４は、細長い平板状に形成され、ハンドル本体３内の収納スペース３４の長手方向の一端側に収納されるとともに、一端から複数のリード線４２が延出されている。これら複数のリード線４２のうち負電極用リード線４２ａの端子４３は、グリップ部材３１の内側に圧入される金属ナット４４と螺合するビス４５により、グリップ部材３１表面の金属メッキ層３５に電気的に接続され、負電極３６を形成している。   The capacitance detection sensor 4 is formed in an elongated flat plate shape, and is stored on one end side in the longitudinal direction of the storage space 34 in the handle body 3, and a plurality of lead wires 42 are extended from one end. Among the plurality of lead wires 42, the terminal 43 of the negative electrode lead wire 42 a is electrically connected to the metal plating layer 35 on the surface of the grip member 31 by a screw 45 screwed with a metal nut 44 press-fitted inside the grip member 31. Are connected to each other to form a negative electrode 36.

ＬＦアンテナ５は、細長い平板状に形成され、収納スペース３４の長手方向の他端側に収納されている。   The LF antenna 5 is formed in an elongated flat plate shape and is stored on the other end side in the longitudinal direction of the storage space 34.

正電極４１は、より細長い平板状に形成され、ハンドル本体３内の収納スペース３４のほぼ全長にわたって延設されるとともに、静電容量検知センサ４及びＬＦアンテナ５とカバー部材３３との間に介在している。   The positive electrode 41 is formed in a longer and narrow flat plate shape, extends over substantially the entire length of the storage space 34 in the handle body 3, and is interposed between the capacitance detection sensor 4 and the LF antenna 5 and the cover member 33. is doing.

上記構成において、ハンドル本体３に内蔵される静電容量検知センサ４の正電極４１が長手方向に延びるとともに、表面の金属メッキ層３５に負電極用リード線４２ａの端子４３が接続され、負電極３６を形成しているので、静電容量検知センサ４の通電により正電極４１及びグリップ部材３１表面の金属メッキ層３５間に電界Ａが形成される。このとき、グリップ部材３１表面の金属メッキ層３５を負電極として用いるとともに、カバー部材３３を絶縁性の合成樹脂材から構成したので、ハンドル本体３内の正電極４１とグリップ部材３１表面の金属メッキ層３５との間で形成される電界Ａを遮断あるいは吸収する物質が存在しないので、電界Ａが乱れたり弱まることを抑制できる。   In the above configuration, the positive electrode 41 of the capacitance detection sensor 4 built in the handle body 3 extends in the longitudinal direction, and the terminal 43 of the negative electrode lead wire 42a is connected to the metal plating layer 35 on the surface. 36 is formed, an electric field A is formed between the positive electrode 41 and the metal plating layer 35 on the surface of the grip member 31 by energization of the capacitance detection sensor 4. At this time, since the metal plating layer 35 on the surface of the grip member 31 is used as a negative electrode and the cover member 33 is made of an insulating synthetic resin material, the positive electrode 41 in the handle body 3 and the metal plating on the surface of the grip member 31 are used. Since there is no substance that blocks or absorbs the electric field A formed between the layers 35, the electric field A can be prevented from being disturbed or weakened.

次いで、アウトサイドドアパネル２の凹部２１に乗員が手を差し入れてグリップ部材３１の裏面側に指先Ｆをかざし、乗員の手がカバー部材３３の周辺の電界Ａを遮ると、電界強度の変化に伴って静電容量検知センサ４の静電容量が変化し、電圧変換してドア解錠操作を行なうようになっている。   Next, when the occupant inserts his hand into the recess 21 of the outside door panel 2 and holds the fingertip F over the back side of the grip member 31, and the occupant's hand blocks the electric field A around the cover member 33, the electric field strength changes. Thus, the capacitance of the capacitance detection sensor 4 is changed, and the voltage is converted to perform the door unlocking operation.

以上、本発明では、グリップ部材３１内の正電極４１とグリップ部材３１表面の金属メッキ層３５からなる負電極３６との間で電界Ａを形成し、乗員の手が電界Ａを遮ったときに、電界強度が変化したことを静電容量検知センサ４で検知するので、人体と他の物質とを識別して確実に検知でき、安定した検知感度が得られる。また、異なる車両に取り付けた場合でも上記電界Ａの強度に差が発生しないため、車両毎の感度調整を要せずにグリップ部材３１の共用化を図ることができ、手間や費用を抑制できる。   As described above, in the present invention, when the electric field A is formed between the positive electrode 41 in the grip member 31 and the negative electrode 36 made of the metal plating layer 35 on the surface of the grip member 31, the passenger's hand blocks the electric field A. Since the capacitance detection sensor 4 detects that the electric field intensity has changed, the human body and other substances can be identified and reliably detected, and stable detection sensitivity can be obtained. In addition, even when attached to different vehicles, there is no difference in the intensity of the electric field A. Therefore, the grip member 31 can be shared without requiring sensitivity adjustment for each vehicle, and labor and cost can be reduced.

また、カバー部材３３がグリップ部材３１のコ字形状部分の内部に配設され、コ字形状の開口端３２がカバー部材３３とともに、ドアの裏面側に向かって露出したことによって、静電容量センサ４の正電極４１と負電極３６とが裏面側に面して隣接配置される。このことによって、静電容量センサ４の電界Ａが安定し、乗員がハンドル本体３の裏面側に指先Ｆをかざした際に起きる電界強度の変化をより確実に検出することができる。   Further, the cover member 33 is disposed inside the U-shaped portion of the grip member 31, and the U-shaped opening end 32 is exposed toward the back side of the door together with the cover member 33, so that the capacitance sensor Four positive electrodes 41 and a negative electrode 36 are arranged adjacent to each other so as to face the back surface side. As a result, the electric field A of the capacitance sensor 4 is stabilized, and the change in electric field strength that occurs when the occupant holds the fingertip F over the back side of the handle body 3 can be detected more reliably.

さらに、静電容量検知センサ４から延出される負電極用リード線４２ａをグリップ部材３１内側に螺合することによって、静電容量検知センサ４をグリップ部材３１表面の金属メッキ層３５に電気的に接続することができるので、容易に負電極用の配線を行ない、グリップ部材３１表面の金属メッキ層３５を負電極として用いることができる。   Furthermore, the electrostatic capacitance detection sensor 4 is electrically connected to the metal plating layer 35 on the surface of the grip member 31 by screwing the negative electrode lead wire 42 a extending from the capacitance detection sensor 4 into the grip member 31. Since they can be connected, the wiring for the negative electrode can be easily performed, and the metal plating layer 35 on the surface of the grip member 31 can be used as the negative electrode.

なお、上記実施形態では、静電容量検知センサ４の正電極４１をグリップ部材３１に内蔵し、負電極をグリップ部材３１表面の金属メッキ層３５から構成した場合を例示したが、本発明はこれに限定されず、静電容量検知センサの負電極をグリップ部材に内蔵し、正電極をグリップ部材表面の金属メッキ層から構成することもできる。   In the above embodiment, the case where the positive electrode 41 of the capacitance detection sensor 4 is built in the grip member 31 and the negative electrode is constituted by the metal plating layer 35 on the surface of the grip member 31 is exemplified. However, the negative electrode of the electrostatic capacitance detection sensor may be built in the grip member, and the positive electrode may be formed of a metal plating layer on the surface of the grip member.
