Description

本発明は、燃料タンクの取付構造に関し、更に詳しくは、例えば燃料電池に用いる水素ガス等の高圧ガスを充填した燃料タンクを車体部材に固定するタンク搭載バンドの取付構造に関する。 The present invention relates to a fuel tank mounting structure, and more particularly to a tank mounting band mounting structure for fixing a fuel tank filled with a high-pressure gas such as hydrogen gas used in a fuel cell to a vehicle body member.

近年、燃料電池に水素ガスと空気を供給して発電し、これによって得られた電気でモータを駆動して走行する燃料電池車両が開発されており、前記水素ガスは、高圧の状態で円筒状の燃料タンクに充填されている。   In recent years, fuel cell vehicles have been developed in which fuel gas is generated by supplying hydrogen gas and air to the fuel cell and the motor is driven by the electricity obtained thereby. The hydrogen gas is cylindrical in a high pressure state. The fuel tank is filled.

従来、この燃料タンクの全周に帯状のタンク搭載バンドを巻き付け、タンク搭載バンドの両端部に締結用ステーを設け、該締結用ステー同士を締結ボルトで連結させると共に、該締結ボルトにスプリングを付勢させた状態で配設することにより、燃料タンクの膨張変位に対応させながら、車体に燃料タンクを取り付けている（例えば、特許文献１参照）。
特開平１０−２７８６０１号公報（第３，４頁、図３参照） Conventionally, a belt-like tank mounting band is wound around the entire circumference of this fuel tank, fastening stays are provided at both ends of the tank mounting band, the fastening stays are connected with fastening bolts, and a spring is attached to the fastening bolt. The fuel tank is attached to the vehicle body in correspondence with the expansion displacement of the fuel tank by being disposed in a biased state (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-278601 (see pages 3 and 4 and FIG. 3)

しかしながら、前記従来の燃料タンクの取付構造においては、スプリングを介して燃料タンクを固定していたため、燃料タンクを保持するタンク搭載バンドの締結トルク管理が困難で、車両が前面衝突等を起こして燃料タンクに大きな荷重が入力した場合に、燃料タンクを安定して保持できないおそれがあった。また、従来は、タンク搭載バンド、締結ボルト及びスプリングなど部品点数が増加し、コストが増加する上に、質量が増して管理値が多くなるため、燃料タンクの取付けの信頼性を確保することが困難であった。   However, in the conventional fuel tank mounting structure, since the fuel tank is fixed via a spring, it is difficult to manage the fastening torque of the tank mounting band that holds the fuel tank, and the vehicle causes a frontal collision and the like. When a large load is input to the tank, there is a possibility that the fuel tank cannot be stably held. In addition, the number of parts such as tank mounting bands, fastening bolts and springs has increased in the past, and the cost has increased, and the mass has increased and the control value has increased, so the reliability of fuel tank mounting can be ensured. It was difficult.

そこで、本発明は、燃料タンクに大きな荷重が入力された場合でも安定して保持することができる燃料タンクの取付構造を提供することを目的としている。   In view of the above, an object of the present invention is to provide a fuel tank mounting structure that can stably hold a large load applied to the fuel tank.

前記目的を達成するために、本発明に係る燃料タンクの取付構造は、燃料タンクを取付具を介して車両後部の車体部材に車幅方向に沿って取り付ける燃料タンクの取付構造であって、前記取付具を、燃料タンクの下部を保持するタンク搭載フレームと、その一端がタンク搭載フレームの前側取付部に固定され、他端がタンク搭載フレームの後側取付部に締結されることによって、前記燃料タンクの上部を保持するタンク搭載バンドとから構成し、前記タンク搭載バンドの車両後側の他端の締結力を可変自在に構成したことを特徴としている。   In order to achieve the above object, a fuel tank mounting structure according to the present invention is a fuel tank mounting structure for mounting a fuel tank along a vehicle width direction to a vehicle body member at the rear of the vehicle via a mounting tool. By attaching the fixture to the tank mounting frame that holds the lower part of the fuel tank, one end thereof is fixed to the front mounting portion of the tank mounting frame, and the other end is fastened to the rear mounting portion of the tank mounting frame. The tank mounting band holds the upper part of the tank, and the fastening force of the other end of the tank mounting band on the vehicle rear side is variable.

本発明に係る燃料タンクの取付構造によれば、タンク搭載バンドの車両前側をタンク搭載フレームに固定しているため、後面衝突などの車両後方から過大荷重が入力した場合における燃料タンクの移動量を最小限度に抑制することができる。即ち、燃料タンクの車両前側を固定することにより、前側の保持力及び剛性が増大するため、車両後部に車幅方向に沿って取り付けられている燃料タンクに車両後方から衝突荷重が入力すると、タンク搭載バンドの前側で燃料タンクの移動を抑止させることができる。   According to the fuel tank mounting structure of the present invention, since the vehicle front side of the tank mounting band is fixed to the tank mounting frame, the amount of movement of the fuel tank when an excessive load is input from the rear of the vehicle, such as a rear collision. It can be suppressed to the minimum. That is, by fixing the front side of the fuel tank to the vehicle, the holding force and rigidity on the front side are increased, so if a collision load is input from the rear of the vehicle to the fuel tank attached to the rear of the vehicle along the vehicle width direction, The movement of the fuel tank can be suppressed on the front side of the mounting band.

また、タンク搭載バンドの後側で締付力（締付けトルク）を調整することができるため、燃料タンクの外形寸法が個々にばらついても、このばらつきを効率的に吸収しつつ、燃料タンクを確実に保持することができる。   In addition, since the tightening force (tightening torque) can be adjusted on the rear side of the tank mounting band, even if the outer dimensions of the fuel tank vary, the fuel tank can be reliably absorbed while absorbing this variation. Can be held in.

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

A belt-like rubber portion 35, which is an elastic material, is provided at a portion that directly contacts the outer peripheral surface of the fuel tank 1. As shown in FIG. 4, the rubber part 35 is provided over the entire length of the tank mounting band 7.

以下に、燃料タンク１をタンク搭載フレーム５に搭載する手順を簡単に説明する。   The procedure for mounting the fuel tank 1 on the tank mounting frame 5 will be briefly described below.

まず、図２に示すように、タンク搭載フレーム５に燃料タンク１を載置し、前記タンク搭載バンド７を燃料タンク１の上面に被せ、この状態で、図６に示すように、ボルト２３を介してタンク搭載バンド７の前端を支持フレーム１７の前端の前側取付部１９にボルト締結する。   First, as shown in FIG. 2, the fuel tank 1 is placed on the tank mounting frame 5, and the tank mounting band 7 is put on the upper surface of the fuel tank 1. In this state, as shown in FIG. Then, the front end of the tank mounting band 7 is bolted to the front mounting portion 19 at the front end of the support frame 17.

次いで、タンク搭載バンド７の後端を支持フレーム１７の後側取付部２９に当接させ、ボルト２３を締結させる。ここで、図６に示すように、タンク搭載バンド７の前端は、タンク搭載フレーム５の支持フレーム１７の前側取付部１９に密着して固定されている。また、タンク搭載バンド７の後端は、ボルト２３と緩み防止用ナット３７（図２参照）を介して支持フレーム１７の後側取付部２９に締結される。そして、図６に示すように、締結する初期段階では、タンク搭載バンド７の後端は支持フレーム１７の後側取付部２９から上方に間隔を隔てて締結されているが、図７に示すように、更にボルト２３を所定トルクに至るまで締結させていく。このように、ボルト２３を締め付けて後端を支持フレーム１７の後側取付部２９に近づけていくと、タンク搭載バンド７が燃料タンク１を締め付けるトルクを所定値にすることができる。   Next, the rear end of the tank mounting band 7 is brought into contact with the rear mounting portion 29 of the support frame 17 and the bolt 23 is fastened. Here, as shown in FIG. 6, the front end of the tank mounting band 7 is fixed in close contact with the front mounting portion 19 of the support frame 17 of the tank mounting frame 5. Further, the rear end of the tank mounting band 7 is fastened to the rear mounting portion 29 of the support frame 17 via a bolt 23 and a loosening prevention nut 37 (see FIG. 2). As shown in FIG. 6, in the initial stage of fastening, the rear end of the tank mounting band 7 is fastened at a distance from the rear mounting portion 29 of the support frame 17, but as shown in FIG. 7. Further, the bolt 23 is further tightened until a predetermined torque is reached. Thus, when the bolt 23 is tightened and the rear end is brought closer to the rear mounting portion 29 of the support frame 17, the torque at which the tank mounting band 7 tightens the fuel tank 1 can be set to a predetermined value.

前記構成を有する燃料タンク１の取付構造によれば、以下の作用効果を有する。   According to the mounting structure of the fuel tank 1 having the above configuration, the following operational effects are obtained.

まず、タンク搭載バンド７の前側を支持フレーム１７の前側取付部１９に固定しているため、タンク搭載バンド７の前側が確実に支持フレーム１７に固定される。よって、車両が例えば後面衝突を起こして、燃料タンク１に車両前方側への荷重が入力された場合に、燃料タンク１の前方への移動を阻止することができる。   First, since the front side of the tank mounting band 7 is fixed to the front mounting portion 19 of the support frame 17, the front side of the tank mounting band 7 is securely fixed to the support frame 17. Therefore, for example, when the vehicle has a rear collision and a load to the front side of the vehicle is input to the fuel tank 1, the forward movement of the fuel tank 1 can be prevented.

また、タンク搭載バンド７の後側を、ボルト２３と緩み防止用ナット３７を介して支持フレーム１７の後側取付部２９にボルト締結するため、タンク搭載バンド７の後側で締結トルクの調整を行うことができる。よって、燃料タンク１の径の大きさが製造上、個々に多少ばらついて作製された場合でも、その燃料タンク１の大きさに応じて、締付代を適宜変えることができ、一定の締結トルクを保持することができる。   Further, since the rear side of the tank mounting band 7 is bolted to the rear mounting portion 29 of the support frame 17 via the bolt 23 and the loosening prevention nut 37, the fastening torque is adjusted on the rear side of the tank mounting band 7. It can be carried out. Therefore, even when the diameter of the fuel tank 1 is slightly varied in manufacturing, the tightening allowance can be appropriately changed according to the size of the fuel tank 1, and a constant fastening torque can be obtained. Can be held.

さらに、支持フレーム１７の後側取付部２９を、平面視で取付フレーム１８の内方に配置したため、車両が後面衝突又は側面衝突を起こした場合にも、後側取付部２９が取付フレーム１８によって保護される。   Further, since the rear mounting portion 29 of the support frame 17 is disposed inward of the mounting frame 18 in a plan view, the rear mounting portion 29 can be moved by the mounting frame 18 even when the vehicle has a rear collision or a side collision. Protected.

また、タンク搭載バンド７の全長に亘って弾性材である帯状のゴム部３５を嵌着したため、燃料タンク１を保持する面圧を燃料タンク１の外周に亘って均一に保持することができる。なお、タンク搭載フレーム５の支持フレーム１７の内側にもゴム部３９からなる弾性材を配設しているため、燃料タンク１の保持面圧が更に均一になる。燃料タンク１を車両に取り付けたのちに燃料タンク１が径方向に膨張又は収縮して、タンク搭載バンド７が燃料タンク１を締め付ける締結力がばらついても、弾性材であるゴム部３５，３９がこの締結力のバラツキを吸収して確実に燃料タンク１を保持することができる。   In addition, since the belt-like rubber portion 35 that is an elastic material is fitted over the entire length of the tank mounting band 7, the surface pressure that holds the fuel tank 1 can be uniformly held over the outer periphery of the fuel tank 1. In addition, since the elastic material which consists of the rubber part 39 is also arrange | positioned inside the support frame 17 of the tank mounting frame 5, the holding surface pressure of the fuel tank 1 becomes still more uniform. Even if the fuel tank 1 expands or contracts in the radial direction after the fuel tank 1 is attached to the vehicle, and the fastening force with which the tank mounting band 7 tightens the fuel tank 1 varies, the rubber portions 35 and 39, which are elastic materials, remain. The fuel tank 1 can be reliably held by absorbing the variation in the fastening force.

そして、図４に示すように、タンク搭載フレーム５を構成する支持フレーム１７の周方向長さは、タンク搭載バンド７の周方向長さよりも小さく構成されている。従って、タンク搭載フレーム５の車両前後方向の長さを小さく抑えて、タンク搭載フレーム５の重量を抑制することができる。なお、図４に示すように、タンク搭載バンド７の両端には、タンク搭載フレーム５と同等の強度を有する締結ブラケット２５，２７が取り付けられており、この締結ブラケット２５，２７によってタンク搭載バンド７の周方向長さを長く設定することができるため、燃料タンク１の締付力を低下させることなく、前記支持フレーム１７の周方向長さを短く設定することができる。また、支持フレーム１７の周方向長さを短く設定できたので、タンク搭載フレーム５の開口部(胴部前後左右フレームに囲まれたスペース)が広くなり、燃料タンク１の搭載時や取外し時の作業性が向上する。   As shown in FIG. 4, the circumferential length of the support frame 17 constituting the tank mounting frame 5 is configured to be smaller than the circumferential length of the tank mounting band 7. Accordingly, the length of the tank mounting frame 5 in the vehicle front-rear direction can be suppressed to be small, and the weight of the tank mounting frame 5 can be suppressed. As shown in FIG. 4, fastening brackets 25 and 27 having the same strength as the tank mounting frame 5 are attached to both ends of the tank mounting band 7, and the tank mounting band 7 is secured by the fastening brackets 25 and 27. The circumferential length of the support frame 17 can be set short without reducing the tightening force of the fuel tank 1. In addition, since the circumferential length of the support frame 17 can be set short, the opening of the tank mounting frame 5 (the space surrounded by the front, rear, left and right frames) becomes wider, and the fuel tank 1 can be mounted or removed. Workability is improved.
