Abstract
Description
本発明は、車両や構造物の緩衝を目的としたエアバッグ装置に関する。 The present invention relates to an airbag device for the purpose of buffering a vehicle or a structure.
従来の車両や構造物の緩衝を目的としたエアバッグ装置は、強固なバッグに膨らんだ状態で圧力を掛けている(特許文献1参照)。
また、バッグ内に圧力センサを設け、バッグ内の圧力を計測すると共に、バッグ全体を圧力センサとしている(特許文献2参照)。A conventional airbag device for buffering a vehicle or a structure applies pressure while being inflated into a strong bag (see Patent Document 1).
Moreover, while providing the pressure sensor in a bag and measuring the pressure in a bag, the whole bag is made into the pressure sensor (refer patent document 2).
以上に述べた従来のエアバッグ装置では、排気する過程での圧力のコントロールが困難であった。 In the conventional airbag apparatus described above, it is difficult to control the pressure during the exhaust process.
また、自動車の衝突の場合は、衝突の速度、形態、対象物の相違により、一定の速度、一定の圧力で減圧しても、一部のケースでしか性能が発揮できない。例えば、同じ速度のオフサイド衝突とフルラップ衝突を比較した場合、同じ安全性能を得る為には緩衝性能を変える必要がある。 Further, in the case of a car collision, due to the difference in the speed, form, and object of the collision, even if the pressure is reduced at a constant speed and a constant pressure, the performance can be exhibited only in some cases. For example, when comparing off-side collision and full-lap collision at the same speed, it is necessary to change the buffer performance in order to obtain the same safety performance.
さらに、従来のダンバーやメンバーで衝突のエネルギーを吸収する方法は、予め想定した事例でしか効果が発揮できず、クラッシュが進に従って性能が著しく低下する。 Further, the conventional method of absorbing the energy of the collision with the dambar or member can be effective only in a case assumed in advance, and the performance is remarkably lowered as the crash progresses.
以下、自動車以外で本発明を応用できる分野での課題を表記する。 Hereinafter, problems in fields where the present invention can be applied other than automobiles will be described.
エレベータでは、落下事故に備えて大きなスプリングをショックアブソーバーとして使用しているが高層階からの落下事故では、スプリングがリバウンドを起こし役に立たない。 In the elevator, a large spring is used as a shock absorber in preparation for a fall accident, but in the fall accident from a higher floor, the spring rebounds and is useless.
電車では、踏切や落石による車両の緩衝対策は取られていない。 On the train, no measures are taken to buffer the vehicle by crossing or falling rocks.
宇宙開発での惑星着地や地球帰還では、袋体のエアバッグ装置を応用しているが、袋体では、圧力を少し下げるだけで力が横方向に逃げ、岩石等に当ると役に立たない。従って、着地点を慎重に選ぶ必要があった。 For planetary landing and space return in space development, a bag airbag device is used. However, if the bag is slightly lowered, the force can escape to the side and hit a rock. Therefore, it was necessary to choose the landing point carefully.
本発明は、従来の構成が有していた問題点を解決しようとするものであり、衝突のエネルギーを効果的に外部へ逃し、安全性の確保を目的としたものである。 The present invention is intended to solve the problems of the conventional configuration, and is intended to effectively release the energy of collision to the outside and ensure safety.
上記課題を解決すための手段として、蛇腹構造に成型した鋼板或いは、カーボン繊維で成型し、さらに、タイヤの技術を応用した硬質ゴムを複合化した高強度複合素材からなり、圧力を受けると規則的に変形するエアバッグと、エアバッグの設定圧力を維持する逆止弁、減圧の過程において、排気の圧力で逆止弁を操作する排気タービンからなるインフレータで構成している。 As a means to solve the above-mentioned problems, it is made of a high-strength composite material that is molded with a steel plate or carbon fiber molded into an accordion structure and combined with a hard rubber that applies the tire technology. And an inflator comprising a check valve for maintaining the set pressure of the airbag and an exhaust turbine for operating the check valve with the pressure of the exhaust in the process of pressure reduction.
上記課題解決手段による作用は次のとおりである。衝突を感知した時点で、インフレータの火薬に点火し、エアバッグ内の圧力を上昇させると共に、同時に逆止弁を前方へ押し出し排気の体制にはいる。排気は逆止弁側面に複数ある排気口から排出される。 The effect | action by the said problem-solving means is as follows. When a collision is detected, the gunpowder of the inflator is ignited to increase the pressure in the airbag, and at the same time, the check valve is pushed forward to enter the exhaust system. Exhaust gas is discharged from a plurality of exhaust ports on the side of the check valve.
激しい衝突で発生した高圧の排気は、排気タービンに回転の作用を及ぼし、後方へ移動し、スプリグを介して連動する逆止弁も後方へ移動し、排気口の面積を小さくすることでエアバッグ内の圧力を持続させる。 The high-pressure exhaust generated by a violent impact exerts a rotating action on the exhaust turbine, moves backward, and the check valve linked with the sprig also moves backward, reducing the area of the exhaust port and reducing the air bag area. Maintain the pressure inside.
また、エアバッグ内の圧力を連続的に測定し、排気タービンをブレーキ操作で排気に抵抗を加え、エアバッグ内部の圧力を適正に制御することで車両の安全と乗員の安全性を確保する。 In addition, the pressure inside the airbag is continuously measured, the exhaust turbine is braked to add resistance to the exhaust, and the pressure inside the airbag is controlled appropriately to ensure vehicle safety and passenger safety.
エレベータでは、エレベータシャフト内の下部に装備し、電車では、先頭車両の連結装置を連結時以外は油圧シリンダーを用いて後方へ収納する方法をとり、前部に装備した本発明のエアバッグ装置で乗員乗客の安全性を確保できる。 Elevators are installed in the lower part of the elevator shaft, and in trains, the connecting device of the leading vehicle is stored rearward using a hydraulic cylinder except when connected, and the airbag device of the present invention installed at the front is used. The safety of passengers can be ensured.
上述したように本発明のエアバッグ装置は、大きなエネルギーを高速で制御し、事故から乗員乗客の安全性確保に止まらず、危険物積載車両の車両自体の安全性を確保する。 As described above, the airbag apparatus of the present invention controls large energy at high speed, and ensures the safety of the vehicle itself of the dangerous goods-carrying vehicle as well as ensuring the safety of passengers from an accident.
また、従来のクラッシュセンサで感知できにくかった電球や道路標識の衝突も容易になり、SRSエアバッグ装置へデータの供給が可能となる。 In addition, it becomes easy to collide with a light bulb or a road sign that was difficult to detect with a conventional crash sensor, and data can be supplied to the SRS airbag device.
