Description

本発明は、車室と後荷室とを隔絶する隔壁と、後荷室に燃料容器を配置した車体後部に関するものである。   The present invention relates to a partition wall that separates a vehicle compartment from a rear cargo compartment, and a vehicle body rear portion in which a fuel container is disposed in the rear cargo compartment.

車体後部には、後荷室に燃料容器、例えば、燃料ボンベを配置したものがある。
この燃料ボンベを配置した車体後部では、燃料ボンベを専用の固定台に載せ一体化した後、後荷室に組み入れて、後部座席のシートバック近傍に配置している(例えば、特許文献1参照)。
また、後部座席のシートバックに近接させて、車室と後荷室とを仕切るパネル(バルクヘッド)を設け、このパネルに車室に連通する開口部を設けたものがある。そして、開口部にX字状に形成した補強バーを取付けることによって、車体後部の強度を高めている(例えば、特許文献2参照)。
In the rear part of the vehicle body, there is one in which a fuel container, for example, a fuel cylinder is arranged in a rear loading chamber.
In the rear part of the vehicle body in which the fuel cylinder is disposed, the fuel cylinder is mounted on a dedicated fixing base and integrated, and then incorporated into the rear luggage compartment and disposed in the vicinity of the seat back of the rear seat (see, for example, Patent Document 1). .
In addition, there is a panel (bulk head) that partitions the vehicle compartment and the rear cargo compartment in the vicinity of the seat back of the rear seat, and an opening that communicates with the vehicle compartment. And the intensity | strength of the vehicle body rear part is raised by attaching the reinforcement bar formed in X shape to the opening part (for example, refer patent document 2).

しかし、従来技術(特許文献1)は、後荷室の前後の長さが短い小型車の場合、燃料ボンベに占有され、後荷室の容積が小さくなる。燃料ボンベをさらに前に移動させると、隔壁に干渉する。干渉を避けるために、隔壁を切り欠いたり、隔壁に開口(開口部)を開けると、車体後部の強度が低下する。   However, in the prior art (Patent Document 1), in the case of a small vehicle having a short front and rear length of the rear loading chamber, it is occupied by the fuel cylinder, and the volume of the rear loading chamber is reduced. If the fuel cylinder is moved further forward, it interferes with the partition wall. In order to avoid interference, if the partition wall is cut out or an opening (opening) is opened in the partition wall, the strength of the rear part of the vehicle body is reduced.

また、特許文献1は、燃料ボンベを専用の固定台(容器保持機構)に載せ一体化した後、後荷室に組み入れている。燃料ボンベを専用の固定台に載せ一体化すると、一体化した物が大型になり、小型車の後荷室に組み入れる際に、車体に干渉し、小型車に搭載できない。   Further, in Patent Document 1, a fuel cylinder is mounted on a dedicated fixing base (container holding mechanism) and integrated, and then incorporated into a rear cargo chamber. If the fuel cylinder is mounted on a dedicated fixed base and integrated, the integrated object becomes large and interferes with the vehicle body when it is incorporated into the rear cargo compartment of a small vehicle, so that it cannot be mounted on the small vehicle.

特許文献2は、後輪から車体の床(フロアパネル)に荷重が入力されると、荷重はX字状の補強バーの下端から補強バーの上部を介してパネルの上部に伝わるが、パネルの下部に荷重を分散できず、パネルの強度を高め難い。結果的に車体後部の強度が低下する恐れがある。よりパネル(バルクヘッド)の強度を高める構造が望まれていた。   In Patent Document 2, when a load is input from the rear wheel to the floor (floor panel) of the vehicle body, the load is transmitted from the lower end of the X-shaped reinforcing bar to the upper part of the panel through the upper part of the reinforcing bar. The load cannot be distributed to the bottom, making it difficult to increase the panel strength. As a result, the strength of the rear part of the vehicle body may be reduced. A structure that further increases the strength of the panel (bulkhead) has been desired.

Next, the hole of the second bar 64 is hooked on the central bolt of the first bar 63. That is, it passes through the hole. Subsequently, the upper end 44 and the lower end 45 (fastening plate 73) of the second bar 64 are temporarily tightened with bolts 124 and 125.
The bolts 121, 122, 124, 125 temporarily tightened with the X-shaped reinforcing bar 43 are finally tightened. Finally, the center of the first bar 63 and the second bar 64 is fastened with a nut.
In a subsequent process, the fuel container 21 is placed on the lower band 88 and the upper band 106 is fastened.

次に、車体後部13の作用を説明する。
このように、車体後部13では、バルクヘッド17に含まれるX字形補強バー43と燃料容器21を保持する容器保持機構18のベースブラケット41を一体化することによって、容器保持機構18の小型化を図り、バルクヘッド17の強度を確保しつつ、燃料容器21をバルクヘッド17より前方に配置して燃料容器21の搭載エリアを縮小することができる。
Next, the operation of the vehicle body rear portion 13 will be described.
As described above, in the vehicle body rear portion 13, the container holding mechanism 18 can be reduced in size by integrating the X-shaped reinforcing bar 43 included in the bulkhead 17 and the base bracket 41 of the container holding mechanism 18 that holds the fuel container 21. As shown, the fuel container 21 can be disposed in front of the bulkhead 17 while the strength of the bulkhead 17 is secured, and the mounting area of the fuel container 21 can be reduced.

「燃料容器21をバルクヘッド17より前方に配置し」とは、図4に示す通り、前方にバルクヘッド17から燃料容器21を距離Bだけ出した状態である。   “The fuel container 21 is disposed in front of the bulkhead 17” means that the fuel container 21 is protruded from the bulkhead 17 by a distance B forward as shown in FIG.

燃料容器21のみを後工程で搭載するので、燃料容器21のみを運び入れる空間を確保すればよく、空間の縮小化が図れ、汎用性が高まる。つまり、採用できる車種が増加するという利点がある。   Since only the fuel container 21 is mounted in a subsequent process, it is sufficient to secure a space for carrying only the fuel container 21, the space can be reduced, and versatility is enhanced. In other words, there is an advantage that the number of vehicles that can be employed increases.

また、車体後部13では、燃料容器21をバルクヘッド17より前方に配置したために、バルクヘッド17は中央の開口27の面積が大きくなり、細くなる(後側壁16からの距離)が、容器保持機構18の横置きバー36をバルクヘッド17の開口27の近傍に固定することによって、バルクヘッド17の強度を補完することできる。   Further, since the fuel container 21 is arranged in front of the bulkhead 17 at the rear body 13, the area of the central opening 27 becomes larger and the bulkhead 17 becomes thinner (distance from the rear side wall 16). The strength of the bulkhead 17 can be supplemented by fixing the 18 horizontal bars 36 in the vicinity of the opening 27 of the bulkhead 17.

さらに、後輪から車体12の床(アンダボデー)に荷重が入力されると、ベースブラケット41および容器保持機構18の縦置きフレーム(タンクサイドビーム)34、35によって、バルクヘッド17の下部に荷重を伝え、さらにバルクヘッド17の中央(ホイールハウス61のガセット61aに連なる上部)から後側壁(リアサイドボデ)16へ荷重を分散することができる。従って、バルクヘッド17の強度を高めることができる。   Further, when a load is input from the rear wheel to the floor (underbody) of the vehicle body 12, the load is applied to the lower portion of the bulkhead 17 by the base bracket 41 and the vertical frames (tank side beams) 34 and 35 of the container holding mechanism 18. In addition, the load can be distributed from the center of the bulkhead 17 (the upper part connected to the gusset 61a of the wheel house 61) to the rear side wall (rear side body) 16. Therefore, the strength of the bulkhead 17 can be increased.

本発明の車体後部は、燃料容器(燃料ボンベ)を搭載した自動車に好適である。   The rear part of the vehicle body of the present invention is suitable for an automobile equipped with a fuel container (fuel cylinder).
