Description

本発明は、自動車などの燃料タンクに使用される燃料タンクの支持体に関する。   The present invention relates to a fuel tank support used for a fuel tank of an automobile or the like.

従来、自動車に搭載される燃料タンクとして、ブロー成形方法などにより樹脂で成形されているものが知られている。こうした樹脂製の燃料タンクは、外気温の変動にしたがって膨張・収縮をするが、こうした膨張収縮に伴う不具合を解消するために、燃料タンク内に撓み防止装置を収納した構成が知られている（特許文献１）。従来の撓み防止装置は、燃料タンクの上下壁にそれぞれ当接する柱状部材と、柱状部材に装着されかつ該柱状部材を軸方向に付勢するスプリングとを備え、燃料タンクの膨張収縮による動きを柱状部材で受けるとともに、その動きをスプリングにより緩和することで燃料タンクの損傷を防止している。   2. Description of the Related Art Conventionally, fuel tanks mounted on automobiles are known which are molded from resin by a blow molding method or the like. Such a resin fuel tank expands and contracts in accordance with fluctuations in the outside air temperature. In order to eliminate the problems associated with such expansion and contraction, a configuration in which a deflection preventing device is housed in the fuel tank is known ( Patent Document 1). The conventional anti-bending device includes a columnar member that abuts on the upper and lower walls of the fuel tank, and a spring that is attached to the columnar member and biases the columnar member in the axial direction. While being received by the member, damage to the fuel tank is prevented by relaxing the movement with a spring.

しかし、従来の撓み防止装置では、柱状部材やスプリングなどの複数の部材を必要とし、構成が複雑になるという問題があった。   However, the conventional deflection preventing apparatus has a problem that a plurality of members such as columnar members and springs are required, and the configuration becomes complicated.

特表２００２−５３６５８６号公報Special table 2002-536586 gazette

本発明は、上記従来の技術の問題点を解決することを踏まえ、耐久性に優れ、かつ簡単な構成の燃料タンクの支持体を提供することを目的とする。   An object of the present invention is to provide a fuel tank support having an excellent durability and a simple configuration in view of solving the above-described problems of the prior art.

本発明は、上述の課題の少なくとも一部を解決するためになされたものであり、以下の形態又は適用例として実現することが可能である。   SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

［適用例１］
適用例１は、燃料タンクに収納され、燃料タンクの内壁であって対向する固定部位にそれぞれ固定されることで燃料タンクの膨張収縮を抑制するための燃料タンクの支持体において、
上記固定部位の一方に固定される支持部材と、該支持部材に接続され上記固定部位の他方に固定されるダンパ部とを備え、
上記ダンパ部は、上記固定部位の他方に固定される第１固定板と、上記支持部材側に接続される第２固定板と、上記第１固定板と第２固定板とを連結するとともに菱形に対向配置したく字形の脚部とを備え、
上記脚部は、上記第１固定板から突出した第１連結部と、上記第２固定板から突出した第２連結部と、上記第１連結部と第２連結部の開放端側に設けられ該第１連結部と第２連結部とを回動可能に軸支する軸受機構とを備えたこと、を特徴とする。 [Application Example 1]
Application Example 1 is a fuel tank support for suppressing expansion and contraction of the fuel tank by being housed in the fuel tank and being fixed to the fixed portions facing each other on the inner wall of the fuel tank.
A support member fixed to one of the fixed parts, and a damper portion connected to the support member and fixed to the other of the fixed parts,
The damper portion connects the first fixing plate fixed to the other of the fixing portions, the second fixing plate connected to the support member side, the first fixing plate and the second fixing plate, and a rhombus And a leg-shaped leg portion arranged opposite to the
The leg portion is provided on a first connecting portion protruding from the first fixing plate, a second connecting portion protruding from the second fixing plate, and an open end side of the first connecting portion and the second connecting portion. A bearing mechanism for pivotally supporting the first connecting portion and the second connecting portion is provided.

適用例１において、外気温の変動にしたがって、燃料タンクの外壁と一体に支持体のダンパ部の脚部が軸受機構で回動しつつ伸縮することで、ダンパ部は、燃料タンクの膨張収縮による変形量を抑制するように抵抗力を加える。   In Application Example 1, the damper portion is caused by expansion and contraction of the fuel tank as the leg portion of the damper portion of the support body expands and contracts while rotating by the bearing mechanism integrally with the outer wall of the fuel tank according to the fluctuation of the outside air temperature. A resistance force is applied so as to suppress the amount of deformation.

また、支持体のダンパ部は、脚部に伸縮方向の力が加わったときに軸受機構の箇所で回動することにより、第１連結部と第２連結部との接合部分である屈曲した箇所に、曲げ弾性力が加わらない。すなわち、ダンパ部の脚部をく字形に一体成形した場合には、屈曲した部分に大きな繰り返し荷重が加わり、耐久性を損なうが、適用例１にかかるダンパ部によれば、このような不具合がなく、繰り返し荷重に対する耐久性を向上させることができる。   Further, the damper portion of the support body is a bent portion that is a joint portion between the first connecting portion and the second connecting portion by rotating at the location of the bearing mechanism when a force in the expansion / contraction direction is applied to the leg portion. In addition, bending elastic force is not applied. That is, when the leg portion of the damper portion is integrally formed in a square shape, a large repeated load is applied to the bent portion and the durability is deteriorated. And durability against repeated loads can be improved.

さらに、支持体のダンパ部は、軸受機構で脚部を一体化すれば簡単に組み付けることができるので、従来の技術で説明したように、柱状部材やスプリングなどの部材を組み付けた構成より簡単である。   Furthermore, since the damper portion of the support body can be easily assembled by integrating the leg portions with a bearing mechanism, as described in the prior art, it is simpler than the configuration in which members such as columnar members and springs are assembled. is there.

［適用例２］
適用例２は、一方の上記脚部は、上記固定部から突出した第１連結部と、上記第２固定板から突出した第２連結部と、上記第１連結部と第２連結部とを回動可能に軸支する軸受機構とを備え、他方の上記脚部は、他方の脚部は、円弧状のヒンジ部を介して第１連結部および第２連結部とを一体に連結するヒンジ部とを備えている構成である。この構成によれば、ダンパ部が一部品になり、構成および製造が簡単になる。 [Application Example 2]
In Application Example 2, one of the leg portions includes a first connecting portion protruding from the fixing portion, a second connecting portion protruding from the second fixing plate, and the first connecting portion and the second connecting portion. The other leg part is a hinge that integrally connects the first connecting part and the second connecting part via an arcuate hinge part. Part. According to this structure, a damper part becomes one part and a structure and manufacture become easy.

（３） 燃料タンクシステムの製造
支持体１０に支持された燃料タンクユニットを製造するには、汎用のブロー成形により行なうことができる。すなわち、ブロー成形機の押出機から、円筒状のパリソンを型開きしている金型のキャビティに押し出すとともに、パリソン内に支持体１０を挿入し、さらにパリソン内にエアーを吹き込み、金型の成形面に倣わせてタンク外壁となるように賦形する。このとき、タンク外壁は、軟化状態のパリソンと支持体１０の上溶着部１５およびダンパ部２０の第１固定板２２で溶着することで支持体１０と一体化する。 (3) Manufacture of fuel tank system The fuel tank unit supported by the support 10 can be manufactured by general-purpose blow molding. That is, while extruding the cylindrical parison from the extruder of the blow molding machine into the mold cavity, the support 10 is inserted into the parison, and air is blown into the parison to mold the mold. It is shaped to be the outer wall of the tank following the surface. At this time, the tank outer wall is integrated with the support 10 by welding the parison in the softened state with the upper welding portion 15 of the support 10 and the first fixing plate 22 of the damper portion 20.

（４） 実施例の作用・効果
上記実施例の構成により、以下の作用・効果を奏する。
（４）−１ 図１および図３に示すように、外気温の変動にしたがって、燃料タンクＦＴの外壁と一体の支持体１０のダンパ部２０の脚部２６，２６が軸受機構２７で回動しつつ伸縮することで、ダンパ部２０は、燃料タンクＦＴの膨張収縮による変形量を抑制するように抵抗力を加える。このとき、変形量が所定以上となったときに、規制部２８が第１固定板２２に当たってダンパ部２０の変形量を規制する。 (4) Actions and effects of the embodiment The following actions and effects are exhibited by the configuration of the above embodiment.
(4) -1 As shown in FIGS. 1 and 3, the leg portions 26 and 26 of the damper portion 20 of the support body 10 integrated with the outer wall of the fuel tank FT are rotated by a bearing mechanism 27 in accordance with fluctuations in the outside air temperature. By expanding and contracting, the damper portion 20 applies a resistance so as to suppress a deformation amount due to expansion and contraction of the fuel tank FT. At this time, when the deformation amount becomes equal to or greater than a predetermined amount, the restricting portion 28 contacts the first fixing plate 22 to restrict the deformation amount of the damper portion 20.

（４）−２ 支持体１０のダンパ部２０は、脚部２６，２６に伸縮方向の力が加わったときに軸受機構２７の箇所で回動することにより、第１連結部２６ａと第２連結部２６ｂとの接合部分である屈曲した箇所に、曲げ弾性力が加わらない。すなわち、比較例にかかる図６に示すように、ダンパ部１００の脚部１０２をく字形に一体成形した場合には、屈曲した部分１０２ａに大きな繰り返し荷重が加わり、耐久性を損なうが、本実施例にかかるダンパ部２０によれば、このような不具合がなく、繰り返し荷重に対する耐久性を向上させることができる。 (4) -2 The damper portion 20 of the support body 10 is rotated at the position of the bearing mechanism 27 when a force in the expansion / contraction direction is applied to the leg portions 26, 26, whereby the first connecting portion 26a and the second connecting portion 26 are connected. The bending elastic force is not applied to the bent portion which is a joint portion with the portion 26b. That is, as shown in FIG. 6 according to the comparative example, when the leg portion 102 of the damper portion 100 is integrally formed in a square shape, a large repeated load is applied to the bent portion 102a and the durability is deteriorated. According to the damper portion 20 according to the example, there is no such inconvenience, and durability against repeated loads can be improved.

（４）−３ 支持体１０のダンパ部２０は、軸受機構２７で脚部２６，２６を一体化すれば簡単に組み付けることができるので、従来の技術で説明したように、柱状部材やスプリングなどの部材を組み付けるより簡単な構成である。 (4) -3 The damper portion 20 of the support 10 can be easily assembled by integrating the leg portions 26 and 26 with the bearing mechanism 27, so as described in the prior art, a columnar member, a spring, etc. This is a simpler configuration than assembling the members.

なお、この発明は上記実施例に限られるものではなく、その要旨を逸脱しない範囲において種々の態様において実施することが可能であり、例えば次のような変形も可能である。   The present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

図６は他の実施例にかかるダンパ部２０Ｂを示す側面図である。本実施例は、ダンパ部２０Ｂの脚部２６Ｂ，２６Ｃの構成に特徴を有する。一方の脚部２６Ｂは、軸受機構２７Ｂを介して第１連結部２６Ｂａと第２連結部２６Ｂｂを回動可能に支持されており、他方の脚部２６Ｃは、円弧状のヒンジ部２８Ｃを介して第１連結部２６Ｃａおよび第２連結部２６Ｃｂを一体に連結している。本実施例によれば、ダンパ部２０Ｂが一部品になり、構成および製造が簡単になる。また、ヒンジ部２８Ｃが円弧状であるから、応力が分散し、耐久性を損なうこともない。また、仮にヒンジ部２８Ｃが破損しても、軸受機構２７Ｂからなる脚部２６Ｂが連結されており、ダンパ部２０Ｂの全体が支持機能を損なうように破損することもない。   FIG. 6 is a side view showing a damper portion 20B according to another embodiment. This embodiment is characterized by the configuration of the leg portions 26B and 26C of the damper portion 20B. One leg portion 26B is rotatably supported by the first connecting portion 26Ba and the second connecting portion 26Bb via a bearing mechanism 27B, and the other leg portion 26C is interposed via an arcuate hinge portion 28C. The first connecting portion 26Ca and the second connecting portion 26Cb are integrally connected. According to the present embodiment, the damper portion 20B becomes one part, and the configuration and manufacture are simplified. Further, since the hinge portion 28C has an arc shape, the stress is dispersed and the durability is not impaired. Even if the hinge portion 28C is damaged, the leg portion 26B composed of the bearing mechanism 27B is connected, and the entire damper portion 20B is not damaged so as to impair the support function.
