Description

本発明は、フロアパネルの下側にバッテリが配置される自動車車両に関する。 The present invention relates to an automobile vehicle in which a battery is arranged under the floor panel.

バッテリを搭載した自動車車両において、フロアパネルの下側にバッテリを配置したものが知られている（例えば、特許文献１及び２参照）。特許文献１及び２に記載の自動車車両では、バッテリの下側にアンダーパネルが設けられる。 It is known that an automobile vehicle equipped with a battery has a battery arranged under a floor panel (see, for example, Patent Documents 1 and 2). In the automobile vehicle described in Patent Documents 1 and 2, an under panel is provided under the battery.

国際公開第２０１０／１３７１５０号International Publication No. 2010/137150 特開平１０−５６７０１号公報Japanese Unexamined Patent Publication No. 10-56701

しかしながら、特許文献１及び２に記載の自動車車両では、段差部通過時に車両の下側が段差部に接触したり、車輪により跳ね上げられた小石が車両の下側に衝突した際に、バッテリの下側に配置される単一のパネルのみでは、外部からの負荷に十分に抗することができずに容易に変形してしまうおそれがある。従って、バッテリの損傷をより確実に防止するため、車両の下側から加えられる負荷に対して十分に抗することのできる構造が望まれている。 However, in the automobile vehicle described in Patent Documents 1 and 2, when the lower side of the vehicle comes into contact with the step portion when passing through the step portion, or when a pebble flipped up by a wheel collides with the lower side of the vehicle, the lower side of the battery is used. A single panel arranged on the side cannot sufficiently withstand the load from the outside and may be easily deformed. Therefore, in order to more reliably prevent damage to the battery, a structure that can sufficiently withstand the load applied from the underside of the vehicle is desired.

本発明は、前記事情に鑑みてなされたものであり、その目的とするところは、フロアパネルの下側にバッテリが配置された自動車車両において、車両の下側から加えられる負荷に対する抗力を増大させることのできる自動車車両を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to increase drag against a load applied from the lower side of a vehicle in an automobile vehicle in which a battery is arranged under the floor panel. It is to provide a vehicle that can be used.

前記目的を達成するため、本発明によれば、車室下部をなすフロアパネルと、前記フロアパネルの下側に間隔をおいて配置され、バッテリを支持する支持パネルと、前記支持パネルの下側に間隔をおいて配置される下面パネルと、前記支持パネルと前記下面パネルとを接続し、前記支持パネル及び前記下面パネルとともに空間を形成する複数の骨格部材と、前記空間に配置され、前記支持パネル及び前記下面パネルと接触する弾性部と、を備えた自動車車両が提供される。 In order to achieve the above object, according to the present invention, the floor panel forming the lower part of the passenger compartment, the support panel arranged at a distance under the floor panel to support the battery, and the lower side of the support panel. A plurality of skeleton members that connect the support panel and the lower surface panel and form a space together with the support panel and the lower surface panel, and the support panel arranged in the space and supported by the lower surface panel. An automobile vehicle comprising a panel and an elastic portion in contact with the lower surface panel is provided.

この自動車車両によれば、車両の下側の障害物や衝突物は、下面パネルと衝突する。下面パネルは、バッテリを支持する支持パネルの下側に各骨格部材を介して設けられているので、十分な強度及び剛性が付与されている。これに加え、支持パネル、下面パネル及び各骨格部材により形成された空間には弾性部が配置されているので、下面パネルへの入力を広範囲で受け止めることができる。これにより、下面パネルの変形量が低減され、下面パネルの塑性変形が抑制される。また、衝撃により下面パネル及び弾性部が一時的に弾性変形しても、下面パネル及び弾性部を元の形状に復元させることができ、実用に際して極めて有利である。 According to this vehicle, obstacles and collisions on the underside of the vehicle collide with the bottom panel. Since the lower surface panel is provided on the lower side of the support panel that supports the battery via each skeleton member, sufficient strength and rigidity are imparted. In addition to this, since the elastic portion is arranged in the space formed by the support panel, the lower surface panel and each skeleton member, the input to the lower surface panel can be received in a wide range. As a result, the amount of deformation of the lower surface panel is reduced, and the plastic deformation of the lower surface panel is suppressed. Further, even if the lower surface panel and the elastic portion are temporarily elastically deformed due to an impact, the lower surface panel and the elastic portion can be restored to their original shapes, which is extremely advantageous in practical use.

上記自動車車両において、前記弾性部は、断熱性を有することが好ましい。 In the automobile vehicle, the elastic portion preferably has a heat insulating property.

この自動車車両によれば、外気温の変動によるバッテリの温度変化を抑制することができる。 According to this automobile vehicle, it is possible to suppress the temperature change of the battery due to the fluctuation of the outside air temperature.

上記自動車車両において、前記弾性部は、流体が充填された袋体とすることができる。 In the automobile vehicle, the elastic portion can be a bag body filled with a fluid.

この自動車車両によれば、流体が充填された袋体は比較的軽量であることから、下面パネルを過度に厚くすることなく、下面パネルに加わる負荷に抗することができ、下面パネルを比較的薄くして車両の軽量化を図ることができる。 According to this automobile vehicle, since the bag body filled with fluid is relatively lightweight, it is possible to withstand the load applied to the bottom panel without making the bottom panel excessively thick, and the bottom panel is relatively lightweight. The weight of the vehicle can be reduced by making it thinner.

上記自動車車両において、前記流体は、気体とすることができる。 In the automobile vehicle, the fluid can be a gas.

この自動車車両によれば、流体として液体を用いた場合よりも袋体を軽量とすることができる。 According to this automobile vehicle, the bag body can be made lighter than the case where a liquid is used as a fluid.

上記自動車車両において、前記バッテリの近傍、及び、前記空間の少なくとも一方に温度調節された空気を流通させる空気流通機構を備えてもよい。 The automobile vehicle may be provided with an air circulation mechanism for circulating temperature-controlled air in the vicinity of the battery and at least one of the spaces.

この自動車車両によれば、バッテリの近傍、及び、空間の少なくとも一方の雰囲気温度を調節することにより、バッテリの温度を制御することができる。 According to this automobile vehicle, the temperature of the battery can be controlled by adjusting the ambient temperature of at least one of the vicinity of the battery and the space.

本発明の自動車車両によれば、フロアパネルの下側にバッテリが配置された自動車車両において、車両の下側から加えられる負荷に対する抗力を増大させることができる。 According to the automobile vehicle of the present invention, in an automobile vehicle in which a battery is arranged under the floor panel, it is possible to increase the drag against a load applied from the lower side of the vehicle.

サイドシル部２０は、左右方向外側に配置されるアウタパネル２１と、左右方向内側に配置されアウタパネル２１とともに袋状の断面を形成するインナパネル２２と、を有する。アウタパネル２１は、正面視の断面にて、上下に延びる側面部と、側面部の上端から上方へ傾斜しつつ左右内側へ延びる上面部と、上面部の左右内端から上方へ延びる上側フランジと、側面部の下端から下方へ傾斜しつつ左右内側へ延びる下面部と、下面部の左右内端から下方へ延びる下側フランジと、を有している。インナパネル２２は、正面視の断面にて、上下に延びる側面部と、側面部の上端から上方へ傾斜しつつ左右外側へ延びる上面部と、上面部の左右外端から上方へ延びる上側フランジと、側面部の下端から下方へ傾斜しつつ左右外側へ延びる下面部と、下面部の左右外端から下方へ延びる下側フランジと、を有している。アウタパネル２１及びインナパネル２２は、各上側フランジ及び各下側フランジにてスポット溶接により接合される。 The side sill portion 20 has an outer panel 21 arranged on the outer side in the left-right direction and an inner panel 22 arranged on the inner side in the left-right direction and forming a bag-shaped cross section together with the outer panel 21. The outer panel 21 has a side surface portion extending vertically, an upper surface portion extending upward from the upper end of the side surface portion to the left and right inward, and an upper flange extending upward from the left and right inner ends of the upper surface portion in a front view. It has a lower surface portion extending inward to the left and right while inclining downward from the lower end of the side surface portion, and a lower flange extending downward from the left and right inner ends of the lower surface portion. The inner panel 22 has a side surface portion extending vertically, an upper surface portion extending upward from the upper end of the side surface portion to the left and right outside, and an upper flange extending upward from the left and right outer ends of the upper surface portion in a front view. It has a lower surface portion extending downward from the lower end of the side surface portion to the left and right outside while being inclined downward, and a lower flange extending downward from the left and right outer ends of the lower surface portion. The outer panel 21 and the inner panel 22 are joined by spot welding at each upper flange and each lower flange.

フロアパネル３０は、サイドシル部２０のインナパネル２２に接続される。本実施形態においては、フロアパネル３０は、正面視の断面にて、左右に延びる本体部３０ａと、本体部３０ａの左右中央に形成され上方へ突出するトンネル部３０ｂと、本体部３０ａの左右外端から上方へ伸びる上側フランジ３０ｃと、を有し、上側フランジ３０ｃがインナパネル２２と溶接等により接続される。 The floor panel 30 is connected to the inner panel 22 of the side sill portion 20. In the present embodiment, the floor panel 30 has a main body portion 30a extending to the left and right, a tunnel portion 30b formed in the center of the left and right of the main body portion 30a and projecting upward, and the left and right outside of the main body portion 30a in a front view. It has an upper flange 30c extending upward from the end, and the upper flange 30c is connected to the inner panel 22 by welding or the like.

支持パネル４０は、サイドシル部２０のインナパネル２２に接続される。支持パネル４０は、フロアパネル３０の下方にてバッテリＢを支持する。本実施形態においては、バッテリＢは、略直方体状を呈し、前後及び左右方向に所定の間隔をおいて支持パネル４０上に並べられる。本実施形態においては、支持パネル４０は、正面視の断面にて、左右方向にわたって略平坦に形成され、左右外端が各インナパネル２２の下面部に溶接により接続される。 The support panel 40 is connected to the inner panel 22 of the side sill portion 20. The support panel 40 supports the battery B below the floor panel 30. In the present embodiment, the batteries B have a substantially rectangular parallelepiped shape and are arranged on the support panel 40 at predetermined intervals in the front-rear and left-right directions. In the present embodiment, the support panel 40 is formed substantially flat in the left-right direction in the cross section in the front view, and the left and right outer ends are connected to the lower surface portion of each inner panel 22 by welding.

下面パネル５０は、各骨格部材６０を介して支持パネル４０に固定される。本実施形態においては、各骨格部材６０は、平面視にて、格子状に配置されている。各骨格部材６０の形状は任意であり、例えば、所定板厚の平坦なパネル部材であってもよいし、支持パネル４０及び下面パネル５０の一方とともに閉塞した断面形状をなす略ハット状のパネル部材であってもよい。 The lower surface panel 50 is fixed to the support panel 40 via each skeleton member 60. In the present embodiment, the skeleton members 60 are arranged in a grid pattern in a plan view. The shape of each skeleton member 60 is arbitrary, and may be, for example, a flat panel member having a predetermined plate thickness, or a substantially hat-shaped panel member having a cross-sectional shape closed together with one of the support panel 40 and the lower surface panel 50. It may be.

支持パネル４０、下面パネル５０及び各骨格部材６０により形成された空間Ｓには、それぞれ袋体７０が配置される。袋体７０には、流体７１が充填されている。すなわち、袋体７０は、断熱性を有している。本実施形態においては、流体７１は気体であり、具体的には空気である。尚、気体として空気以外のものを用いてもよく、不活性ガスを用いると安全性が向上するし、熱伝導率の比較的低い気体を用いると断熱性能が向上する。不活性ガスとしては、アルゴン、ヘリウム等の希ガスの他、例えば、窒素、二酸化炭素を挙げることができる。熱伝導率の比較的低い気体としては、例えば、アルゴン、二酸化炭素を挙げることができる。尚、流体７１として、液体を用いてもよいことは勿論である。袋体７０は、空間Ｓを略埋めるように配置されている。従って、下面パネル５０の上側は、各骨格部材６０と接続している領域を除いて、各袋体７０によりほぼ覆われている。 A bag body 70 is arranged in the space S formed by the support panel 40, the lower surface panel 50, and each skeleton member 60. The bag body 70 is filled with the fluid 71. That is, the bag body 70 has a heat insulating property. In this embodiment, the fluid 71 is a gas, specifically air. A gas other than air may be used as the gas, and the safety is improved by using an inert gas, and the heat insulating performance is improved by using a gas having a relatively low thermal conductivity. Examples of the inert gas include rare gases such as argon and helium, as well as nitrogen and carbon dioxide. Examples of the gas having a relatively low thermal conductivity include argon and carbon dioxide. Of course, a liquid may be used as the fluid 71. The bag body 70 is arranged so as to substantially fill the space S. Therefore, the upper side of the lower surface panel 50 is substantially covered by each bag body 70 except for the region connected to each skeleton member 60.

以上のように構成された自動車車両１０によれば、図２に示すように、車両の下側の障害物や衝突物は、下面パネル５０と衝突する。下面パネル５０は、バッテリＢを支持する支持パネル４０の下側に各骨格部材６０を介して設けられているので、十分な強度及び剛性が付与されている。これに加え、支持パネル４０、下面パネル５０及び各骨格部材６０により形成された空間Ｓには袋体７０が配置されているので、下面パネル５０にてより大きい入力に抗することができる。これにより、下面パネル５０の変形量が低減され、下面パネル５０の塑性変形が抑制される。従って、バッテリＢの保護を的確に行うことができる。また、図２に示すように衝撃により下面パネル及び弾性部が一時的に弾性変形しても、下面パネル及び弾性部を元の形状に復元させることができ、実用に際して極めて有利である。 According to the automobile vehicle 10 configured as described above, as shown in FIG. 2, obstacles and collision objects on the lower side of the vehicle collide with the lower surface panel 50. Since the lower surface panel 50 is provided on the lower side of the support panel 40 that supports the battery B via each skeleton member 60, sufficient strength and rigidity are imparted. In addition to this, since the bag body 70 is arranged in the space S formed by the support panel 40, the lower surface panel 50, and each skeleton member 60, the lower surface panel 50 can resist a larger input. As a result, the amount of deformation of the lower surface panel 50 is reduced, and the plastic deformation of the lower surface panel 50 is suppressed. Therefore, the battery B can be properly protected. Further, as shown in FIG. 2, even if the lower surface panel and the elastic portion are temporarily elastically deformed by an impact, the lower surface panel and the elastic portion can be restored to the original shape, which is extremely advantageous in practical use.

また、流体７１が充填された袋体７０は比較的軽量であることから、下面パネル５０を過度に厚くすることなく、下面パネル５０に加わる負荷に抗することができ、下面パネル５０を比較的薄くして車両の軽量化を図ることができる。さらに、袋体７０の流体７１として気体を用いているので、流体７１を液体として場合と比べて格段に軽量である。
さらにまた、袋体７０が断熱性を有するので、外気温の変動によるバッテリＢの温度変化を抑制することができる。 Further, since the bag body 70 filled with the fluid 71 is relatively lightweight, it is possible to withstand the load applied to the lower surface panel 50 without making the lower surface panel 50 excessively thick, and the lower surface panel 50 is relatively lightweight. The weight of the vehicle can be reduced by making it thinner. Further, since gas is used as the fluid 71 of the bag body 70, the weight of the fluid 71 is much lighter than that of the case where the fluid 71 is used as a liquid.
Furthermore, since the bag body 70 has a heat insulating property, it is possible to suppress the temperature change of the battery B due to the fluctuation of the outside air temperature.

ここで、例えば図３及び図４に示すように、バッテリＢの近傍と空間Ｓの少なくとも一方に、温度調節された空気を流通させる空気流通機構を備えるようにし、バッテリＢの温度を積極的に制御するようにしてもよい。図３は、前記実施形態の自動車車両１０において、空調装置にて温度調節された空気が供給されるダクト８０が、バッテリＢの近傍に配置された状態を示す。また、図４は、前記実施形態の自動車車両１０において、袋体７０に、空調装置から温度調節された空気が供給される供給孔９０が形成された状態を示す。袋体７０は、供給孔９０とは別個に空気の排出孔が形成されており、流体７１としての空気の温度が制御される。 Here, for example, as shown in FIGS. 3 and 4, an air flow mechanism for circulating temperature-controlled air is provided in at least one of the vicinity of the battery B and the space S, and the temperature of the battery B is positively adjusted. It may be controlled. FIG. 3 shows a state in which the duct 80 to which the temperature-controlled air is supplied by the air conditioner is arranged in the vicinity of the battery B in the automobile vehicle 10 of the embodiment. Further, FIG. 4 shows a state in which a supply hole 90 for supplying temperature-controlled air from the air conditioner is formed in the bag body 70 in the automobile vehicle 10 of the embodiment. The bag body 70 is formed with an air discharge hole separately from the supply hole 90, and the temperature of the air as the fluid 71 is controlled.

また、前記実施形態においては、弾性部として流体７１が充填された袋体７０を示したが、弾性部の構成は空間Ｓ内で支持パネル４０及び下面パネル５０と接触していれば任意に変更することができ、例えば弾性部をスポンジ状のウレタン材とすることもできる。 Further, in the above-described embodiment, the bag body 70 filled with the fluid 71 is shown as the elastic portion, but the configuration of the elastic portion can be arbitrarily changed as long as it is in contact with the support panel 40 and the lower surface panel 50 in the space S. For example, the elastic portion can be made of a sponge-like urethane material.

以上、本発明の実施の形態を説明したが、上記に記載した実施の形態は特許請求の範囲に係る発明を限定するものではない。また、実施の形態の中で説明した特徴の組合せの全てが発明の課題を解決するための手段に必須であるとは限らない点に留意すべきである。 Although the embodiments of the present invention have been described above, the embodiments described above do not limit the invention according to the claims. It should also be noted that not all combinations of features described in the embodiments are essential to the means for solving the problems of the invention.
