Description

本発明は、車体内部を通過するホース類の位置決めを図ることができる自動車の換気装置に関する。   The present invention relates to a ventilating device for an automobile capable of positioning hoses passing through a vehicle body.

自動車の換気装置とは、自動車のリヤフェンダに換気用開口を設けて室内と車外とを連通させ、走行中にリヤバンパ付近に発生する負圧を利用して室内の空気を車外に導出して換気を行い、また、ドア閉時の耳鳴り防止などを行うシステムである。従来のこの種の換気装置は、この換気用開口に、負圧の作用で開くワンウエイバルブを備えたベンチレータを装着し、このベンチレータの外側をリヤバンパによって覆うようにしている(特許文献1)。   An automobile ventilator is a ventilation fender in the rear fender of an automobile that connects the interior of the vehicle with the outside of the vehicle, and uses the negative pressure generated in the vicinity of the rear bumper while driving to vent the indoor air to the outside of the vehicle. This system also prevents tinnitus when the door is closed. In this type of conventional ventilator, a ventilator provided with a one-way valve that opens by the action of negative pressure is attached to the ventilation opening, and the outside of the ventilator is covered with a rear bumper (Patent Document 1).

一方、サンルーフ等のルーフ部に降った雨水等はドレンホースを通して、車室外に排水している。このドレンホースから排出する雨水が車室内に流入するのを防止するため、ベンチレータに取り付けられたクリップでドレンホースを留めて排水穴まで案内する構造が知られている(特許文献2参照)。

しかしながら、上記従来技術によると、ドレンホースを留めるためのクリップを改めてベンチレータに取り付ける必要があり、作業が煩雑であり、コスト増となってしまう。また、従来構造にあるドレンホースを留めるための構造をベンチレータに一体で設けるには複雑な成形型を必要とする。   However, according to the above prior art, it is necessary to reattach the clip for fastening the drain hose to the ventilator, which makes the operation complicated and increases the cost. Further, in order to integrally provide the ventilator with a structure for fastening the drain hose in the conventional structure, a complicated mold is required.

本発明は、上記課題を解決し、別部品を設けることなく、車体内部を通過するホース類の動きを規制することができる自動車の換気装置を提供することを目的とする。 An object of the present invention is to solve the above-mentioned problems and to provide an automobile ventilation device that can regulate the movement of hoses that pass through the inside of a vehicle body without providing separate parts.

本発明は、上記課題を解決するため、リヤバンパの側面部内面に対向するアウターパネルに開口穴を形成し、該開口穴にベンチレータを装着した自動車の換気装置において、ベンチレータの通気穴に車両搭載状態で縦方向に複数の仕切り壁を設けるとともに、該仕切り壁のうち少なくとも一対の仕切り壁に車内側に延長する延長部を形成し、これら仕切り壁の延長部相互間にホース類を配置したことにある。
また、本発明は、上記延長部を車体内面を形成する車体パネル近傍まで延長したことにある。
さらに、本発明は、上記ホース類が水抜き穴の方向に向くように上記延長部を仕切り壁に沿って縦方向に延設したことにある。
In order to solve the above problems, the present invention provides an automotive ventilator in which an opening hole is formed in the outer panel facing the inner surface of the side surface of the rear bumper, and a ventilator is attached to the opening hole. In addition to providing a plurality of partition walls in the vertical direction, at least a pair of partition walls of the partition walls is formed with an extension portion extending toward the vehicle interior, and hoses are disposed between the extension portions of the partition walls. is there.
Further, the present invention resides in that the extension portion is extended to the vicinity of the vehicle body panel forming the inner surface of the vehicle body.
Furthermore, the present invention resides in that the extension portion extends in the vertical direction along the partition wall so that the hoses are directed in the direction of the drain hole.

以下、図示の実施の形態を図面を参照しながら詳細に説明する。
図1は自動車の換気装置を示す車体の側面図、図2は図1の部分拡大図、図3はホース類を配置した状態の換気装置部分を、一部車体パネルを省略して示す斜視図、図4は図2のA−A線断面図、図5ないし図7は換気装置を示す図、図8は図7の換気装置の車両取付状態を示すB−B線概念断面図である。
Hereinafter, the illustrated embodiment will be described in detail with reference to the drawings.
1 is a side view of a vehicle body showing an automobile ventilation device, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. 3 is a perspective view showing a ventilation device portion in a state in which hoses are arranged, partially omitting a vehicle body panel. 4 is a cross-sectional view taken along the line AA in FIG. 2, FIGS. 5 to 7 are views showing the ventilator, and FIG. 8 is a conceptual cross-sectional view taken along the line BB showing the vehicle mounted state of the ventilator shown in FIG.

図1ないし図4において、1は自動車の車体2に設けられた換気装置で、この換気装置1はリヤバンパ3の内側のサイドボデイアウタパネル(アウタパネル)4に装着されている。このサイドボデイアウタパネル4の内側には所定の間隔で車体パネル5が配設されている。   In FIG. 1 to FIG. 4, reference numeral 1 denotes a ventilator provided on a vehicle body 2, and this ventilator 1 is mounted on a side body outer panel (outer panel) 4 inside a rear bumper 3. Inside the side body outer panel 4, vehicle body panels 5 are arranged at a predetermined interval.

上記換気装置1は、負圧またはドア閉め時の室内圧による作用で一方に開く遮蔽板、いわゆるワンウエイバルブ6を備えたベンチレータ7で、このベンチレータ7は、図5ないし図7に示すように四辺からなる枠体71と、縦方向の複数の仕切り壁72を設けたものである。このベンチレータ7は樹脂成形させたもので、複数の仕切り壁72のうち少なくとも一対の仕切り壁72(図示例では左右両側の各一対の仕切り壁72)には、室内側の車体パネル5の近傍まで延長する延長部72a,72bが設けられて成形されている。サイドボデイアウタパネル4から一対の仕切り壁72の延長部72a,72b先端までの突出長さL1は、サイドボデイアウタパネル4から車体パネル5までの間隔L2と、ドレンホース8の直径Rとから、L2-L1<Rを満足するように設定する。
一対の仕切り壁72の延長部72a,72bには上端部72a1,72b1が上部枠71aよりも突出するように延出され、かつ上端部72a1,72b1の対向面には互いに僅かに近づくフランジ部72a2,72b2が形成されて、入り口のみ狭くして、ドレンホース8の位置決め、および挿入組付けを容易にしている。こうして、仕切り壁72の延長部72a,72bおよびフランジ部72a2,72b2相互によって、ドレンホース8の動きを規制している。
上記ベンチレータ7には、ベンチレータ7の上部枠71aに上端部6aを支持されたワンウエイバルブ6が垂設されて、通常状態では、上記ベンチレータ7の通気穴73を遮蔽している。ワンウエイバルブ6は、ドアを閉めたり、車体外側との圧力差が生じると仕切り壁72から離れる方向に回動し、ベンチレータ7を開放して、室内の圧力を外部に排出するものである。ワンウエイバルブ6が閉じた状態では、仕切り壁72に当接してそれ以上の動きが規制されている。
The ventilator 1 is a ventilator 7 provided with a shielding plate, ie, a so-called one-way valve 6, which opens to one side by the action of negative pressure or indoor pressure when the door is closed, and this ventilator 7 has four sides as shown in FIGS. And a plurality of vertical partition walls 72 are provided. The ventilator 7 is formed by resin molding, and at least a pair of the partition walls 72 (in the illustrated example, the pair of partition walls 72 on both the left and right sides) extends to the vicinity of the vehicle body panel 5 on the indoor side. Extending extensions 72a and 72b are provided and molded. The projecting length L1 from the side body outer panel 4 to the ends of the extension portions 72a and 72b of the pair of partition walls 72 is determined by the distance L2 from the side body outer panel 4 to the vehicle body panel 5 and the diameter R of the drain hose 8 L2- Set so as to satisfy L1 <R.
Upper ends 72a1 and 72b1 extend from the extension portions 72a and 72b of the pair of partition walls 72 so as to protrude from the upper frame 71a, and flange portions 72a2 that are slightly close to the opposing surfaces of the upper ends 72a1 and 72b1. 72b2 is formed so that only the inlet is narrowed to facilitate the positioning and insertion assembly of the drain hose 8. Thus, the movement of the drain hose 8 is regulated by the extension portions 72a and 72b of the partition wall 72 and the flange portions 72a2 and 72b2.
In the ventilator 7, a one-way valve 6 having an upper end portion 6 a supported by an upper frame 71 a of the ventilator 7 is suspended, and the vent hole 73 of the ventilator 7 is shielded in a normal state. The one-way valve 6 rotates in a direction away from the partition wall 72 when the door is closed or a pressure difference from the outside of the vehicle body occurs, opens the ventilator 7 and discharges the indoor pressure to the outside. When the one-way valve 6 is closed, further movement is restricted by contacting the partition wall 72.

一方、上記一対の仕切り壁の延長部72a,72bと車体パネル5とで囲まれた枠S内には、ルーフ部から流れる雨水等を排出するためのドレンホース8が配置されている。このドレンホース8の下端部は一対の仕切り壁72の延長部72a,72bによって車体パネル5等に形成された排水穴(図示せず)まで位置決めされている。   On the other hand, a drain hose 8 for discharging rainwater flowing from the roof portion is disposed in a frame S surrounded by the extension portions 72a and 72b of the pair of partition walls and the vehicle body panel 5. The lower end portion of the drain hose 8 is positioned up to a drain hole (not shown) formed in the vehicle body panel 5 and the like by the extension portions 72a and 72b of the pair of partition walls 72.

上記構成によると、換気装置1は、通常状態では、上記ベンチレータ7の通気穴73をワンウエイバルブ6が遮蔽している。ワンウエイバルブは、仕切り壁72に当接してそれ以上の室内側への回動は規制されている。
そして、ワンウエイバルブ6の外側に、例えばドアを閉めたりして、車体外側との圧力差が生じると、ワンウエイバルブ6は開放し、通気穴73を通して車室内の圧力を抜く作用を行う。
こうして、ベンチレータ7の少なくとも一対の仕切り壁72の延長部72a,72bを室内側の車体パネル5の近傍まで延長させて成形しているので、この一対の仕切り壁72の延長部72a,72bと車体パネル5とで囲まれた枠S内にドレンホース8を位置決めして配置することができる。こうして、ドレンホース8は仕切り壁72の延長部72a,72b相互間に規制されて、車体パネル5等に形成された排水穴まで位置決めされる。
したがって、ドレンホース8から排出される雨水等が車室内に流入する不具合を防ぐことができる。また、一対の仕切り壁72の延長部72a,72bをベンチレータ7の成形時に室内側の車体パネル5の近傍まで達する長さに成形すればよいので、別部品を用いる必要がないことから、経済的で、かつドレンホース8の位置決めを確実に行うことができる。
According to the above configuration, in the ventilation device 1, the one-way valve 6 shields the vent hole 73 of the ventilator 7 in a normal state. The one-way valve is in contact with the partition wall 72 and further rotation to the indoor side is restricted.
Then, for example, when a door is closed on the outside of the one-way valve 6 to cause a pressure difference with the outside of the vehicle body, the one-way valve 6 is opened, and the pressure in the vehicle compartment is released through the vent hole 73.
Thus, since the extension portions 72a and 72b of at least the pair of partition walls 72 of the ventilator 7 are formed to extend to the vicinity of the vehicle body panel 5 on the indoor side, the extension portions 72a and 72b of the pair of partition walls 72 and the vehicle body are formed. The drain hose 8 can be positioned and arranged in a frame S surrounded by the panel 5. In this way, the drain hose 8 is regulated between the extension portions 72a and 72b of the partition wall 72, and is positioned up to the drainage hole formed in the vehicle body panel 5 or the like.
Therefore, it is possible to prevent a problem that rainwater or the like discharged from the drain hose 8 flows into the vehicle interior. Further, since the extension portions 72a and 72b of the pair of partition walls 72 may be formed to a length that reaches the vicinity of the vehicle body panel 5 on the indoor side when the ventilator 7 is formed, there is no need to use separate parts. In addition, the drain hose 8 can be reliably positioned.

なお、本発明は、上記実施の形態のみに限定されるものではなく、例えば、一対の仕切り壁72の延長部72a,72bと車体パネル5とで囲まれた枠S内にドレンホース8を配置したが、ホース類のものであればドレンホース8に限らず、配置することができる。また、ベンチレータ7に一体成形した一対の仕切り壁72の延長部72a,72bは、ホース類が多ければ、ベンチレータ7の両側に成形しても良く、ホース類が1本であれば、片側にのみ一対の仕切り壁72の延長部72a,72bを成形しても良い。また、換気装置1は車体の左右いずれの側に設けることもできるなど、その他、本発明の要旨を変更しない範囲内で適宜変更して実施し得ることは言うまでもない。   The present invention is not limited to the above-described embodiment. For example, the drain hose 8 is disposed in the frame S surrounded by the extension portions 72a and 72b of the pair of partition walls 72 and the vehicle body panel 5. However, if it is a thing of hoses, it can arrange not only the drain hose 8 but. Further, the extension portions 72a and 72b of the pair of partition walls 72 formed integrally with the ventilator 7 may be formed on both sides of the ventilator 7 if there are many hoses, and if there is one hose, only one side is formed. The extensions 72a and 72b of the pair of partition walls 72 may be formed. Further, it goes without saying that the ventilation device 1 can be provided on either the left or right side of the vehicle body, and can be implemented with appropriate modifications within a range not changing the gist of the present invention.
