Description

この発明は車両用センサの保護構造に係り、特に、車両の側面衝突時に車両用ドア内に配置した車両用センサを保護することができる車両用センサの保護構造に関する。 The present invention relates to a vehicle sensor protection structure, and more particularly to a vehicle sensor protection structure capable of protecting a vehicle sensor disposed inside a vehicle door when a side collision of the vehicle occurs.

車両においては、搭載された各種装置を制御する情報を得るために、車載用センサを車体の各部に配置している。これら車両用センサを衝突による荷重から保護する技術としては、特許文献1、特許文献2に開示されるものがある。
特許文献1には、車両の前後方向に延びるフロントフレームの前端近傍部に補強板で補強された非クラッシュ部を形成し、非クラッシュ部内にエアバッグセンサを配置することで、正面衝突時にエアバッグセンサの姿勢が変動することを防止した構造が開示されている。
特許文献2には、車両用ドアのインナパネルに車両外側方向に突出する凹部を形成し、凹部の底部にエアバッグ装置の側突センサを取り付け、側突センサと側面視で重なる位置にスペーサを設けることで、側突センサが配置された領域の剛性を高めて、側突時(車両の側面衝突時)の加速度を側突センサに効率的に伝達させ、衝突加速度の検知時間を短縮させた構造が開示されている。
In a vehicle, in-vehicle sensors are arranged at various parts of the vehicle body in order to obtain information for controlling various mounted devices. Techniques for protecting these vehicle sensors from a load due to a collision include those disclosed in Patent Documents 1 and 2.
In Patent Literature 1, a non-crash portion reinforced by a reinforcing plate is formed in the vicinity of a front end of a front frame extending in the front-rear direction of a vehicle, and an airbag sensor is arranged in the non-crash portion, so that an airbag can be used in a frontal collision. A structure is disclosed in which the attitude of the sensor is prevented from changing.
In Patent Document 2, a concave portion projecting toward the vehicle outer side is formed in an inner panel of a vehicle door, a side collision sensor of an airbag device is attached to a bottom portion of the concave portion, and a spacer is provided at a position overlapping the side collision sensor in a side view. By providing the side impact sensor, the rigidity of the area where the side impact sensor is arranged is increased, the acceleration at the time of a side impact (at the time of a side collision of the vehicle) is efficiently transmitted to the side impact sensor, and the collision acceleration detection time is shortened. A structure is disclosed.

ところで、車両用センサには、特許文献2に開示されるように、車両用ドアのインナパネルに形成した車両外側に突出する凹部の底部に取り付け、インナパネルと車体内側のドアトリムとの間配置する構造のものがある。これに対して、車両用センサには、車両用ドアのインナパネルとアウタパネルとの間に配置する構造のものがある。
しかしながら、インナパネルとアウタパネルとの間に車両用センサを配置した構造においては、車両用ドアへの衝突(車両の側面衝突)によりアウタパネルが車両内側に変形した場合、インナパネルと変形したアウタパネルとの間に車両用センサが挟まれ、アウタパネルから衝突による荷重が車両用センサに作用して破損するという課題がある。
By the way, as disclosed in Patent Document 2, the vehicle sensor is attached to the bottom of a recess formed in the inner panel of the vehicle door and protruding to the outside of the vehicle, and is disposed between the inner panel and the door trim inside the vehicle body. There is a structure. On the other hand, some vehicle sensors have a structure arranged between an inner panel and an outer panel of a vehicle door.
However, in the structure in which the vehicle sensor is arranged between the inner panel and the outer panel, when the outer panel is deformed inside the vehicle due to a collision with the vehicle door (side collision of the vehicle), the inner panel and the deformed outer panel are separated from each other. There is a problem that the vehicle sensor is sandwiched between them, and a load due to a collision from the outer panel acts on the vehicle sensor to damage it.

この発明は、車両の側面衝突による荷重が車両用ドアに加わった際に、車両用ドア内に配置された車両用センサヘの車両用ドア変形による荷重の作用を抑制し、車両用センサを保護することを目的とする。 This invention protects a vehicle sensor by suppressing the action of the load on the vehicle sensor disposed inside the vehicle door due to the deformation of the vehicle door when the load due to the side collision of the vehicle is applied to the vehicle door. The purpose is to

この発明は、車両用ドアのインナパネルとアウタパネルとの間に配置した車両用センサの保護構造であって、前記インナパネルの平坦部分には前記平坦部分より車両内側方向に凹む収容部が一体的に設けられ、前記収容部は、平面視で三角形となるように形成され、前記車両用センサを前記収容部内に収まるように配置しており、前記収容部の周縁の前部及び後部のそれぞれには、前記アウタパネル方向に突出し、車両上下方向に延びる凸形状が前記平坦部分に設けられていることを特徴とする。 The present invention is a protective structure for a vehicle sensor arranged between an inner panel and an outer panel of a vehicle door, wherein a flat portion of the inner panel is integrally provided with a housing portion that is recessed inward from the flat portion toward a vehicle inner side. The housing portion is formed so as to have a triangular shape in a plan view, and the vehicle sensor is arranged so as to be housed in the housing portion, and is provided at each of a front portion and a rear portion of a peripheral edge of the housing portion. Is characterized in that a convex shape protruding in the outer panel direction and extending in the vehicle vertical direction is provided in the flat portion .

この発明は、インナパネルに一体形成した収容部内に車両用センサを配置することで、車両用ドアへの衝突時にアウタパネルが変形しても、インナパネルと変形したアウタパネルとの間に車両用センサが挟み込まれることがないので、車両用センサを保護することができる。 According to the present invention, by arranging the vehicle sensor in the accommodating portion formed integrally with the inner panel, even if the outer panel is deformed at the time of a collision with the vehicle door, the vehicle sensor is provided between the inner panel and the deformed outer panel. Since it is not caught, the vehicle sensor can be protected.

図1は車両外側から見たインナパネルの正面図である。(実施例)FIG. 1 is a front view of the inner panel viewed from the outside of the vehicle. (Example) 図2は車両上側から見たインナパネルとアウタパネルの平面図である。(実施例)FIG. 2 is a plan view of the inner panel and the outer panel viewed from the upper side of the vehicle. (Example)

以下、図面に基づいて、この発明の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.

図1、図2は、この発明の実施例を示すものである。図1、図2において、車両用ドア1は、車両内側部材を構成するインナパネル2と、車両外側部材を構成するアウタパネル3と、を備えている。インナパネル2の車両内側は、ドアトリムにより覆われている。
車両用ドア1は、インナパネル2とアウタパネル3との間に、車両用センサ4を配置している。車両用センサ4は、例えば、車両用ドア1内の圧力を検出する圧力センサなどからなる。圧力センサの検出する圧力情報は、サイドエアバッグ装置の制御に使用される。
車両用センサ4の保護構造は、インナパネル2に車両内側方向に凹ませた収容部5を一体形成している。収容部5は、インナパネル2の平坦部分6の一部を車両内側方向に向かいV字形状に凹ませることで、アウタパネル3に向かい開口する開口部分7の両端から車両内側方向に向かいV字形状に延びる2つの斜壁部分8・9を備え、平面視にて三角形の収容空間10を有する形状に形成される。
収容部5の周縁の平坦部分6には、アウタパネル3の方向(車両外側方向)に突出した凸形状の支持部11・12を設けている。支持部11・12は、車両上下方向に延びるように形成され、収容部5の収容空間10を幅方向両側から挟むように配置している。
車両用センサ4は、開口部分7からアウタパネル3の方向に突出しないように、一方の斜壁部分8に取付ボルトなどの取付具13により取り付けられる。これにより、車両用センサ4は、収容部5の収容空間10内に収まるように配置している。
1 and 2 show an embodiment of the present invention. 1 and 2, the vehicle door 1 includes an inner panel 2 that constitutes a vehicle inner member and an outer panel 3 that constitutes a vehicle outer member. The vehicle inner side of the inner panel 2 is covered with a door trim.
The vehicle door 1 has a vehicle sensor 4 arranged between an inner panel 2 and an outer panel 3. The vehicle sensor 4 includes, for example, a pressure sensor that detects the pressure inside the vehicle door 1. The pressure information detected by the pressure sensor is used to control the side airbag device.
In the protective structure of the vehicle sensor 4, the inner panel 2 is integrally formed with a housing portion 5 that is recessed in the vehicle inner direction. The accommodating portion 5 is formed by recessing a part of the flat portion 6 of the inner panel 2 toward the vehicle inner side in a V shape so that the housing portion 5 has a V shape toward the vehicle inner side from both ends of the opening portion 7 opening toward the outer panel 3. It has two slanted wall portions 8 and 9 extending in the shape of a triangle, and is formed in a shape having a triangular accommodation space 10 in a plan view.
In the flat portion 6 at the periphery of the housing portion 5, there are provided convex-shaped support portions 11 and 12 projecting in the direction of the outer panel 3 (vehicle outer direction). The support portions 11 and 12 are formed so as to extend in the vehicle vertical direction, and are arranged so as to sandwich the accommodation space 10 of the accommodation portion 5 from both sides in the width direction.
The vehicle sensor 4 is attached to one of the slanted wall portions 8 by a mounting tool 13 such as a mounting bolt so as not to project from the opening portion 7 toward the outer panel 3. As a result, the vehicle sensor 4 is arranged so as to be accommodated in the accommodation space 10 of the accommodation portion 5.

車両用センサ4の保護構造は、インナパネル2に一体形成した収容部5内に車両用センサ4を配置することで、車両用センサ4が開口部分7からアウタパネル3の方向に突出しないようにしている。
これにより、車両用センサ4の保護構造は、車両用ドア1への衝突時(側面衝突時)に、アウタパネル3が図2の矢印Aで示す方向に移動して2点鎖線で示すように変形しても、インナパネル2と変形したアウタパネル3との間に車両用センサ4が挟み込まれることがない。
このため、車両用センサ4の保護構造は、車両用ドア1の変形による荷重が車両用センサ4ヘ作用することを抑制し、車両用センサ4を保護することができる。
また、車両用センサ4の保護構造は、収容部5の周縁にアウタパネル3の方向に突出した凸形状の支持部11・12を設けている。
これにより、車両用センサ4の保護構造は、車両用センサ4を固定する収容部5の剛性を向上させることができ、また、側面衝突時の荷重を受けてアウタパネル3が変形した際、アウタパネル3が凸形状の支持部11・12に当接し、これ以上の変形を抑制することができ、さらに、アウタパネル3の変形による荷重をインナパネル2の凸形状の支持部11・12で受け止め、アウタパネル3と車両用センサ4が接触するのを防止できる。
なお、収容部5は、アウタパネル3に向かい開口する開口部分7の両端から車両内側方向に向かいV字形状に延びる2つの斜壁部分8・9を同一の長さとし、平面視にて二等辺三角形の収容空間10を有する形状に形成することで、収容部5の剛性が高くなり、潰れにくくすることができ、また、開口部分7を狭くして変形したアウタパネル3が収容部5内に入りにくくすることができ、側面衝突時の荷重から車両用センサ4を保護することができる。
The protective structure of the vehicle sensor 4 is arranged so that the vehicle sensor 4 does not project from the opening portion 7 in the direction of the outer panel 3 by disposing the vehicle sensor 4 in the housing portion 5 formed integrally with the inner panel 2. There is.
As a result, the protective structure of the vehicle sensor 4 is deformed as shown by the chain double-dashed line when the outer panel 3 moves in the direction indicated by the arrow A in FIG. 2 when the vehicle door 1 collides with the vehicle door 1 (side collision). However, the vehicle sensor 4 is not sandwiched between the inner panel 2 and the deformed outer panel 3.
Therefore, the protective structure for the vehicle sensor 4 can prevent the load due to the deformation of the vehicle door 1 from acting on the vehicle sensor 4 and protect the vehicle sensor 4.
Further, the protective structure of the vehicle sensor 4 is provided with convex support portions 11 and 12 projecting toward the outer panel 3 on the periphery of the housing portion 5.
As a result, the protective structure for the vehicle sensor 4 can improve the rigidity of the housing portion 5 that fixes the vehicle sensor 4, and when the outer panel 3 is deformed under the load of a side collision, the outer panel 3 is deformed. Contact the supporting portions 11 and 12 having a convex shape, and further deformation can be suppressed. Further, the load due to the deformation of the outer panel 3 is received by the supporting portions 11 and 12 having a convex shape of the inner panel 2, and the outer panel 3 The vehicle sensor 4 can be prevented from coming into contact with the vehicle sensor 4.
In addition, in the accommodation portion 5, two slanted wall portions 8 and 9 extending in a V shape toward the vehicle inner side from both ends of the opening portion 7 opening toward the outer panel 3 have the same length, and are isosceles triangles in a plan view. When the outer panel 3 is formed in a shape having the accommodating space 10, the rigidity of the accommodating portion 5 can be increased and the collapsing can be prevented, and the outer panel 3 that is deformed by narrowing the opening portion 7 is unlikely to enter the accommodating portion 5. Therefore, the vehicle sensor 4 can be protected from the load at the time of a side collision.

この発明は、車両用ドアへの衝突時にアウタパネルが変形しても、インナパネルと変形したアウタパネルとの間に車両用センサが挟み込まれることがなく、車両用センサを保護することができるものであり、車両用センサに限らず、車両用ドア内に配置される車両部品の保護に利用することが可能である。 According to the present invention, even if the outer panel is deformed at the time of collision with the vehicle door, the vehicle sensor is not sandwiched between the inner panel and the deformed outer panel, and the vehicle sensor can be protected. Not only the vehicle sensor, but it can be used for protection of vehicle parts arranged in the vehicle door.
