Description

本発明は、ルーフパネルの前端部に配設されたヘッダパネルにルームミラーを支持させるようにした自動車のルームミラー支持構造に関する。   The present invention relates to an automobile rearview mirror support structure in which a rearview mirror is supported by a header panel disposed at a front end portion of a roof panel.

自動車のルーフ部は、ルーフパネルの前縁部によりヘッダパネルを片持ち支持する構造が一般的である。このような片持ち支持されたヘッダパネルの後側部分にルームミラー取付け位置を設定すると、上下方向の車体振動等によってルームミラーにびびり振動が発生し、後方視界を悪化させるおそれがある。   The roof portion of an automobile generally has a structure in which the header panel is cantilevered by the front edge portion of the roof panel. If the rearview mirror mounting position is set on the rear portion of the header panel supported by such a cantilever, chatter vibration may occur in the rearview mirror due to vertical body vibration or the like, which may deteriorate the rear view.

このようなルームミラーのびびり振動を防止するために、従来、例えば特許文献１には、ルーフインナパネル（ヘッダパネル）にリインホースを配設し、該リインホースとルーフインナパネルとで閉断面部を形成することでルームミラーの支持剛性を高めるようにした構造が開示されている。   In order to prevent such chatter vibration of the rearview mirror, conventionally, for example, in Patent Document 1, a rein hose is provided on a roof inner panel (header panel), and a closed cross-section is formed by the rein hose and the roof inner panel. Thus, a structure is disclosed in which the support rigidity of the rearview mirror is increased.

特開平９−３０１０７０号公報JP-A-9-301070

ところで、前記従来のように、リインホースを追加して閉断面を形成することでルームミラーの支持剛性を高める構造では、新たにリインホースを追加する分だけ車体重量及びコストが上昇するという問題点がある。   By the way, in the structure which increases the support rigidity of the rearview mirror by adding a rein hose to form a closed cross section as in the conventional case, there is a problem that the vehicle body weight and cost increase by adding a new rein hose. .

本発明は、前記従来の状況に鑑みてなされたもので、車体重量やコストの上昇といった問題を招くことなく、ルームミラーのびびり振動を防止できる自動車のルームミラー支持構造を提供することを課題としている。   The present invention has been made in view of the above-described conventional situation, and it is an object of the present invention to provide a vehicle rearview mirror support structure that can prevent chatter vibration of a rearview mirror without causing problems such as an increase in vehicle body weight or cost. Yes.

本発明は、ルーフパネルと該ルーフパネルの前端部に配設された車幅方向に延びるヘッダパネルとの前フランジ部同士を結合し、該ヘッダパネルにルームミラーを支持させるようにした自動車のルームミラー支持構造において、前記ルーフパネルと前記ヘッダパネルの後縁部との間に、両者の隙間を埋める閉塞部材を配置し、該閉塞部材の下面に前記ヘッダパネルの後縁部が当接する摺動部材を配置したことを特徴としている。   The present invention relates to a vehicle room in which front flange portions of a roof panel and a header panel disposed in a front end portion of the roof panel and extending in the vehicle width direction are coupled to each other so that a rearview mirror is supported by the header panel. In the mirror support structure, a sliding member is disposed between the roof panel and the rear edge portion of the header panel so as to fill a gap between the roof panel and the rear edge portion of the header panel. It is characterized by arranging members.

本発明に係るルームミラー支持構造によれば、ルーフパネルとヘッダパネルの後縁部との隙間に閉塞部材を配置し、該閉塞部材の下面にヘッダパネルの後縁部が当接する摺動部材を配置したので、ヘッダパネルに伝わる上下方向の車体振動等の運動エネルギーは、ヘッダパネルの後縁部が摺動部材に摺接することで前後方向の摩擦エネルギーに変換されることとなる。このように上下方向の運動エネルギーを前後方向の摩擦エネルギーに変換させることで減衰させるので、ルームミラーのびびり振動を抑制することができる。これによりルームミラーの取付位置に対する自由度を高めることができるとともに、後方視界を確保することができる。   According to the rearview mirror support structure according to the present invention, the closing member is disposed in the gap between the roof panel and the rear edge portion of the header panel, and the sliding member with which the rear edge portion of the header panel contacts the lower surface of the closing member is provided. Since it has been arranged, kinetic energy such as vertical vehicle body vibration transmitted to the header panel is converted into frictional energy in the front-rear direction when the rear edge of the header panel is in sliding contact with the sliding member. As described above, the kinetic energy in the vertical direction is attenuated by converting it into the frictional energy in the front-rear direction, so that chatter vibration of the rearview mirror can be suppressed. Thereby, while being able to raise the freedom degree with respect to the attachment position of a room mirror, a back view can be ensured.

また本発明では、ヘッダパネルの後縁部を摺動部材に摺接させることで車体振動を減衰させる構成であるので、従来のようなリインホースを追加して支持剛性を高める場合に比べて車体重量及びコストの上昇を抑制できる。   Further, according to the present invention, the vehicle body vibration is attenuated by sliding the rear edge portion of the header panel against the sliding member. Therefore, the vehicle body weight is increased as compared with the case where the support rigidity is increased by adding a rein hose as in the prior art. In addition, an increase in cost can be suppressed.

The cabin 1 includes a front part 3 provided with a headlight 2, a left and right side part 5 provided with a door 4, and the left and right side parts. It has a structure in which a vehicle compartment R is formed by a back panel 6 and a roof portion 7 disposed at the rear end of the side portion 5. In addition, 9 is a loading platform.

前記ルーフ部７，左，右のサイド部５及びフロント部３により囲まれた開口にはフロントガラス８が配設されている。 A windshield 8 is disposed in the opening surrounded by the roof portion 7, the left and right side portions 5 and the front portion 3.

前記ルーフ部７は、外装面を有するルーフパネル１０と、該ルーフパネル１０の室内側に敷設された天井部材１２と、前記ルーフパネル１０の前端部１０ａに車幅方向に延びるように配設されたヘッダパネル１１とを備えている。   The roof portion 7 is disposed to extend in the vehicle width direction on a roof panel 10 having an exterior surface, a ceiling member 12 laid on the indoor side of the roof panel 10, and a front end portion 10 a of the roof panel 10. Header panel 11.

前記ルーフパネル１０の前端部１０ａには、前フランジ部１０ｂが段落ち形成され、前記ヘッダパネル１１の前端部１１ａには、前記前フランジ１０ｂの下面に当接する前フランジ部１１ｂが屈曲形成されており、該前フランジ部１０ｂ，１１ｂ同士はスポット溶接により結合されている。この前フランジ部１０ｂ，１１ｂの結合部に前記フロントガラス８の上縁部８ａが不図示のシール部材を介して取り付けられている。   A front flange portion 10b is formed at the front end portion 10a of the roof panel 10, and a front flange portion 11b that is in contact with the lower surface of the front flange 10b is bent at the front end portion 11a of the header panel 11. The front flange portions 10b and 11b are coupled to each other by spot welding. An upper edge portion 8a of the windshield 8 is attached to a joint portion of the front flange portions 10b and 11b via a seal member (not shown).

前記ヘッダパネル１１は、前記前端部１１ａに続いて後方に延びる平板部１１ｃと、該平板部１１ｃに続いて斜め後上方に屈曲して延びる後端部１１ｄとを有する。   The header panel 11 has a flat plate portion 11c that extends rearward after the front end portion 11a, and a rear end portion 11d that bends and extends obliquely rearward and upward following the flat plate portion 11c.

この後端部１１ｄと前記ルーフパネル１０との間には所定の隙間ｓが設けられており、これによりヘッダパネル１１はルーフパネル１０により片持ち支持されている。   A predetermined gap s is provided between the rear end portion 11 d and the roof panel 10, whereby the header panel 11 is cantilevered by the roof panel 10.

前記ヘッダパネル１１の平板部１１ｃの車幅方向中央部には、ミラー取付座１１ｅが形成されており、該取付座１１ｅにルームミラー１５が取り付けられている。   A mirror mounting seat 11e is formed at a central portion in the vehicle width direction of the flat plate portion 11c of the header panel 11, and a room mirror 15 is mounted on the mounting seat 11e.

このルームミラー１５は、車両後方を視認するミラー本体１５ａと、該ミラー本体１５ａに接続された取付けブラケット１５ｂとを有する。この取付けブラケット１５ｂは、前記ヘッダパネル１１のミラー取付座１１ｅにボルト締め固定されており、該取付けブラケット１５ｂの室内側はカバー部材１６により覆われている。なお、１７は取付けブラケット１５ｂに取り付けられたルームランプであり、該ルームランプ１７が点灯すると前記カバー部材１６に配設されたレンズ（不図示）を透して室内を照射する。   This rear mirror 15 has a mirror main body 15a for visually recognizing the rear of the vehicle, and a mounting bracket 15b connected to the mirror main body 15a. This mounting bracket 15b is bolted and fixed to the mirror mounting seat 11e of the header panel 11, and the interior side of the mounting bracket 15b is covered with a cover member 16. Reference numeral 17 denotes a room lamp attached to the mounting bracket 15b. When the room lamp 17 is turned on, the room lamp is irradiated through a lens (not shown) disposed on the cover member 16.

そして前記ルーフパネル１０と前記ヘッダパネル１１の後端部１１ｄと隙間ｓには、該隙間ｓを埋める閉塞部材２０が配置されており、該閉塞部材２０の下面２０ａには、前記後端部１１ｄの上端面１１ｆが当接する摺動部材２１が配置されている。   The roof panel 10 and the rear end portion 11d of the header panel 11 and the gap s are provided with a closing member 20 that fills the gap s. The lower surface 20a of the closing member 20 has the rear end portion 11d. The sliding member 21 with which the upper end surface 11f of the abutment comes into contact is arranged.

前記閉塞部材２０は、前記ルームミラー１５のミラー取付座１１ｅに対応する車幅寸法を有し、前記ルーフパネル１０に接着固定されている。この閉塞部材２０は、弾性を有する部材，例えばウレタンチップにより構成されており、図２に二点鎖線で示すように僅かな弾性変形ａを有する状態でルーフパネル１０とヘッダパネル１１とで挟持されている。   The closing member 20 has a vehicle width dimension corresponding to the mirror mounting seat 11e of the rearview mirror 15, and is adhesively fixed to the roof panel 10. The closing member 20 is made of an elastic member, for example, a urethane chip, and is sandwiched between the roof panel 10 and the header panel 11 with a slight elastic deformation a as shown by a two-dot chain line in FIG. ing.

また前記摺動部材２１は、前記閉塞部材２０に接着固定されており、潤滑機能を有する薄板状の例えばＰＰ（ポリプロピレン）材により構成されている。   The sliding member 21 is bonded and fixed to the closing member 20, and is made of a thin plate-like material such as PP (polypropylene) having a lubricating function.

本実施例では、ルーフパネル１０とヘッダパネル１１の後端部１１ｄとの隙間ｓに、ウレタンチップからなる閉塞部材２０を配置し、該閉塞部材２０の下面２０ａに前記後端部１１ｄの上端面１１ｆが当接するＰＰ材からなる摺動部材２１を配置したので、車体振動等による上下方向ａの運動エネルギーは、ヘッダパネル１１の上端面１１ｆが摺動部材２１に接した状態で前後方向ｂに摺動することで摩擦エネルギーに変換されることとなる。このように上下方向ａの運動エネルギーを前後方向ｂの摩擦エネルギーに変換することで減衰させるので、ルームミラー１５のびびり振動を防止することができる。これによりルームミラー１５の取付位置に対する自由度を高めることができ、ひいてはヘッダパネル１１の後部に設定することが可能なる。またルームミラー１５のびびり振動が防止されるので、後方視界を確保することができる。 In this embodiment, a closing member 20 made of a urethane chip is disposed in the gap s between the roof panel 10 and the rear end portion 11d of the header panel 11, and the upper end surface of the rear end portion 11d is disposed on the lower surface 20a of the closing member 20. Since the sliding member 21 made of PP material with which 11f abuts is disposed, the kinetic energy in the vertical direction a due to vibration of the vehicle body or the like is in the longitudinal direction b with the upper end surface 11f of the header panel 11 in contact with the sliding member 21. By sliding, it is converted into friction energy. As described above, since the kinetic energy in the vertical direction a is attenuated by converting it into the friction energy in the front-rear direction b, chatter vibration of the rearview mirror 15 can be prevented. Thereby, the freedom degree with respect to the attachment position of the room mirror 15 can be raised, and it becomes possible to set to the rear part of the header panel 11 by extension. Moreover, since the chatter vibration of the room mirror 15 is prevented, a rear view can be secured.

また本実施例では、前記ヘッダパネル１１の後端部１１ｄを樹脂製の閉塞部材２０を介在させて同じく樹脂製の摺動部材２１に摺接させることで車体振動を減衰させる構成であるので、従来のような金属製のリインホースを別途追加してルームミラーの支持剛性を高める場合に比べて車体重量及びコストの上昇を抑制できる。   Further, in this embodiment, the rear end portion 11d of the header panel 11 is slidably contacted with the resin sliding member 21 with the resin closing member 20 interposed therebetween, so that the vehicle body vibration is attenuated. Compared to the case where a metal rein hose is added separately as in the conventional case to increase the support rigidity of the rearview mirror, an increase in vehicle weight and cost can be suppressed.
