Description

本明細書が開示する技術は、座席の下にバッテリを配置する車載構造に関する。   The technology disclosed in this specification relates to an in-vehicle structure in which a battery is disposed under a seat.

例えば、ハイブリッド車は、モータを駆動するためのバッテリを備える。当該バッテリの設置場所としては、客室内、荷室内など、様々な場所が提案されている。例えば、特許文献１には、客室内にてバッテリを後部座席の下に配置する車載構造が開示されている。   For example, a hybrid vehicle includes a battery for driving a motor. Various places such as a cabin and a cargo room have been proposed as installation locations of the battery. For example, Patent Document 1 discloses an in-vehicle structure in which a battery is disposed under a rear seat in a cabin.

特許文献１に開示されるバッテリの車載構造では、後部座席の座部の裏面と当該裏面と対向するバッテリの上面との間に、空気経路が設けられている。空気経路の一端は、後部座席の前下側（即ち、乗客の足元側）で開口しており、他端は、バッテリの上面の吸入口と連通している。客室内の空気は、上記の空気経路を通過してバッテリ内に吸入される。吸入された空気により、バッテリのケース内のバッテリ本体が冷却される。   In the on-vehicle structure of the battery disclosed in Patent Document 1, an air path is provided between the back surface of the seat portion of the rear seat and the upper surface of the battery facing the back surface. One end of the air path opens at the front lower side of the rear seat (that is, the passenger's foot side), and the other end communicates with the suction port on the upper surface of the battery. Air in the cabin passes through the air path and is sucked into the battery. The battery body in the battery case is cooled by the sucked air.

特開２００１−２３３０６４号公報Japanese Patent Laid-Open No. 2001-233064

車両の用途の多様化により、客室内の空間を利用して、大きな荷物を載せる要望が高まっている。客室内の空間を利用するために、座席を変形し、座席の上の空間を広げることが考えられる。例えば、座部を乗員の足元の空間に移動し、元々の座部の位置へ背もたれを前方に倒すように変形する。元々の座部の位置の下にバッテリが配置されている場合、座席を上記のとおりに変形すると、バッテリの前方の空間が座部と背もたれで覆われる。特許文献１の車載構造では、空気経路が後部座席の前下側に開口しているため、後部座席が上記のごとく変形すると、当該開口から流入する空気の流量が低下する虞がある。本明細書では、前面に通風口が設けられているバッテリを座席の下に配置する車載構造において、座席を変形しても通風口から十分に空気を取り込むことが可能な構造を提供する。   Due to the diversification of vehicle applications, there is an increasing demand for loading large luggage using the space in the cabin. In order to use the space in the cabin, it is possible to change the seat and widen the space above the seat. For example, the seat is moved to the space under the occupant's feet and deformed so that the backrest is tilted forward to the original position of the seat. When the battery is arranged below the original position of the seat, when the seat is deformed as described above, the space in front of the battery is covered with the seat and the backrest. In the in-vehicle structure of Patent Document 1, since the air path opens to the front lower side of the rear seat, when the rear seat is deformed as described above, the flow rate of air flowing from the opening may be reduced. In the present specification, an in-vehicle structure in which a battery having a vent hole on the front surface is disposed under a seat, a structure capable of sufficiently taking in air from the vent hole even when the seat is deformed is provided.

本明細書が開示するバッテリの車載構造は、座席と、座席の座部の下に配置されており、前面に通風口が設けられているバッテリを備えている。座席は、座部が、その裏面がバッテリの前面と対向するように位置し、背もたれが、その表面がバッテリの上面と対向するとともに背もたれの肩部が座部の裏面と近接するように位置する折り畳み姿勢に変形可能である。そして、座部の裏面と背もたれの少なくとも一方に、座席が折り畳み姿勢にあるときに背もたれの上方の空間と通風口を連通する通風通路が設けられている。   The on-vehicle structure of a battery disclosed in the present specification includes a seat and a battery that is disposed under the seat portion of the seat and has a vent hole on the front surface. The seat is positioned so that the back of the seat faces the front of the battery and the backrest faces the top of the battery and the shoulder of the back is close to the back of the seat It can be transformed into a folded position. Further, at least one of the back surface and the backrest of the seat is provided with a ventilation passage that communicates the space above the backrest and the ventilation opening when the seat is in the folded posture.

この構成によれば、座席が折り畳み姿勢にあるとき、バッテリの前方の空間が、座部の裏面と背もたれの肩部で覆われる。このとき、上記の前方の空間には、背もたれの上方の空間から、座部の裏面と背もたれの少なくとも一方に設けられている通風通路を介して、空気が流入する。このため、座席が折り畳み姿勢にあるときでも、通風口から十分に空気を取り込むことができる。本明細書が開示する技術の詳細とさらなる改良は以下の「発明を実施するための形態」にて説明する。   According to this configuration, when the seat is in the folded position, the space in front of the battery is covered with the back surface of the seat portion and the shoulder portion of the backrest. At this time, air flows into the front space from the space above the backrest through a ventilation passage provided on at least one of the back surface of the seat and the backrest. For this reason, even when the seat is in the folded position, air can be sufficiently taken in from the ventilation opening. Details and further improvements of the technology disclosed in this specification will be described in the following “DETAILED DESCRIPTION”.

後部座席３は、乗客の頭部を支持するヘッドレスト１２と、乗客の背中を支持する背もたれ１３と、乗客の臀部を支持する座部１４を備えている。ヘッドレスト１２は、背もたれ１３の肩部に取り付けられており、背もたれ１３から取り外し可能である。後述するが、後部座席３は、折り畳み姿勢（図２参照）に変形可能である。図１に示すような乗客が着座可能な後部座席の姿勢を、以下、「通常姿勢」と称する。   The rear seat 3 includes a headrest 12 that supports the passenger's head, a backrest 13 that supports the passenger's back, and a seat 14 that supports the passenger's buttocks. The headrest 12 is attached to the shoulder portion of the backrest 13 and is removable from the backrest 13. As will be described later, the rear seat 3 can be transformed into a folded posture (see FIG. 2). The posture of the rear seat on which a passenger can be seated as shown in FIG. 1 is hereinafter referred to as “normal posture”.

図２を参照して、後部座席の折り畳み姿勢について説明する。折り畳み姿勢では、座部１４が、その裏面４１がバッテリ６の前面６３と対向するように位置する。そして、背もたれ１３が、その表面３３がバッテリ６の上面６４と対向するとともにその肩部３４が座部１４の裏面４１と接するように位置している。折り畳み姿勢では、バッテリ６の前方の空間Ｓ１は、座部１４の裏面４１と背もたれ１３の肩部３４により覆われる。   The folding posture of the rear seat will be described with reference to FIG. In the folded posture, the seat 14 is positioned such that the back surface 41 faces the front surface 63 of the battery 6. The backrest 13 is positioned such that its front surface 33 faces the upper surface 64 of the battery 6 and its shoulder portion 34 contacts the back surface 41 of the seat portion 14. In the folded posture, the space S <b> 1 in front of the battery 6 is covered with the back surface 41 of the seat portion 14 and the shoulder portion 34 of the backrest 13.

図３及び図４を参照して、通常姿勢から折り畳み姿勢に変形する様子について説明する。図３は、座部１４を折り畳み姿勢における位置に移動する様子を示す斜視図である。図３では、通常姿勢における座部１４の位置を破線で示している。破線に示すように、座部１４は、通常姿勢では、バッテリ６の上面６４の上に位置している。座部１４とバッテリ６は、可倒式のシートレッグ４２により接続されている。シートレッグ４２の一端は、座部１４の前端に固定されており、他端は、バッテリ６の前面６３に回転可能に支持されている。座部１４は、シートレッグ４２の他端を支点に回転することにより、座部１４の裏面４１がバッテリ６の前面６３と対向する位置まで移動可能である。なお、図３に示すように、座部１４の裏面４１には、３本の溝４１ａ−４１ｃが設けられている。溝４１ａ−４１ｃは、折り畳み姿勢において、上下方向に平行に延びている。別言すれば、溝４１ａ−４１ｃは、通常姿勢において、前後方向に平行に延びている。   With reference to FIG.3 and FIG.4, a mode that it deform | transforms from a normal attitude | position to a folding attitude | position is demonstrated. FIG. 3 is a perspective view showing a state in which the seat portion 14 is moved to a position in the folded posture. In FIG. 3, the position of the seat portion 14 in the normal posture is indicated by a broken line. As shown by the broken line, the seat 14 is positioned on the upper surface 64 of the battery 6 in the normal posture. The seat 14 and the battery 6 are connected by a retractable seat leg 42. One end of the seat leg 42 is fixed to the front end of the seat portion 14, and the other end is rotatably supported by the front surface 63 of the battery 6. The seat portion 14 can move to a position where the back surface 41 of the seat portion 14 faces the front surface 63 of the battery 6 by rotating around the other end of the seat leg 42. As shown in FIG. 3, the back surface 41 of the seat portion 14 is provided with three grooves 41 a to 41 c. The grooves 41a-41c extend in parallel to the vertical direction in the folded posture. In other words, the grooves 41a-41c extend parallel to the front-rear direction in the normal posture.

図４は、背もたれ１３を折り畳み姿勢における位置に回転する様子を示す斜視図である。図４では、座部１４は、図３に示す位置まで既に移動している。図４では、通常姿勢における背もたれ１３の位置を破線で示している。破線に示すように、背もたれ１３は、通常姿勢では、上下方向に立っている。背もたれ１３の下端は、バッテリ６の上面に回転可能に支持されている。これにより、背もたれ１３は、前方に向かって回転可能である。背もたれ１３が前方に向かって回転すると、その表面３３はバッテリ６の上面と対向する。   FIG. 4 is a perspective view showing a state in which the backrest 13 is rotated to a position in the folded posture. In FIG. 4, the seat 14 has already been moved to the position shown in FIG. In FIG. 4, the position of the backrest 13 in the normal posture is indicated by a broken line. As shown by the broken line, the backrest 13 stands in the vertical direction in the normal posture. The lower end of the backrest 13 is rotatably supported on the upper surface of the battery 6. Thereby, the backrest 13 can rotate toward the front. When the backrest 13 rotates forward, its surface 33 faces the upper surface of the battery 6.

図４に示すように、後部座席３を折り畳み姿勢にする場合、先ず、座部１４を図３に示す位置まで移動する。その後、背もたれ１３を図４に示すように前方に回転する。これにより、後部座席３を通常姿勢から折り畳み姿勢に変形することができる。なお、図４に示すように、背もたれ１３の肩部３４には、背もたれ１３の裏面３１から表面３３に貫通する２個の貫通孔３２ａ、３２ｂが設けられている。また、２個の貫通孔３２ａ、３２ｂの裏面３１側の開口の夫々は、通気性の良いメッシュ布３１ａ、３１ｂにより覆われている。   As shown in FIG. 4, when the rear seat 3 is folded, first, the seat 14 is moved to the position shown in FIG. 3. Thereafter, the backrest 13 is rotated forward as shown in FIG. Thereby, the rear seat 3 can be deformed from the normal posture to the folded posture. As shown in FIG. 4, the shoulder portion 34 of the backrest 13 is provided with two through holes 32 a and 32 b penetrating from the back surface 31 of the backrest 13 to the front surface 33. The openings on the back surface 31 side of the two through holes 32a and 32b are covered with mesh cloths 31a and 31b having good air permeability.

図５を参照して、バッテリ６の構成について説明する。図５は、後部座席３及びバッテリ６の正面図である。バッテリ６のバッテリケース６１の前面６３には、３個の通風口６３ａ−６３ｃが設けられている。バッテリケース６１に収容されているバッテリ本体（図５では不図示）は、各通風口から流入する空気により冷却される。各通風口には、バッテリケース６１内に異物が侵入することを防止するための格子状のフィルタが取り付けられている。なお、変形例では、前面６３には、少なくとも１個の通風口が設けられていればよい。   The configuration of the battery 6 will be described with reference to FIG. FIG. 5 is a front view of the rear seat 3 and the battery 6. Three ventilation holes 63 a to 63 c are provided on the front surface 63 of the battery case 61 of the battery 6. The battery main body (not shown in FIG. 5) accommodated in the battery case 61 is cooled by the air flowing from the ventilation openings. A lattice-like filter for preventing foreign matter from entering the battery case 61 is attached to each ventilation port. In the modification, the front surface 63 may be provided with at least one ventilation port.

また、図５に示すように、上記した２個の貫通孔３２ａ、３２ｂの表面３３側の開口の夫々も、裏面３１側の開口と同様に、通気性の良いメッシュ布３３ａ、３３ｂにより覆われている。なお、図５に示すように、貫通孔３２ａ（３２ｂ）は、ヘッドレスト１２の下に設けられている。即ち、貫通孔３２ａ（３２ｂ）は、後部座席３に座る乗客の肩が接しない位置に設けられており、後部座席３の座り心地に影響しない。なお、変形例では、貫通孔３２ａ（３２ｂ）は、後部座席３に座る乗客の肩が接しない位置であれば、ヘッドレスト１２の下以外に設けられてもよい。   Further, as shown in FIG. 5, each of the openings on the front surface 33 side of the two through holes 32a and 32b described above is covered with mesh fabrics 33a and 33b having good air permeability, similarly to the opening on the rear surface 31 side. ing. As shown in FIG. 5, the through hole 32 a (32 b) is provided under the headrest 12. That is, the through hole 32 a (32 b) is provided at a position where the shoulder of the passenger sitting on the rear seat 3 does not contact, and does not affect the sitting comfort of the rear seat 3. In the modified example, the through-hole 32a (32b) may be provided other than under the headrest 12 as long as the shoulder of the passenger sitting on the rear seat 3 is not in contact therewith.

図６を参照して、折り畳み姿勢において、通風口６３ａに流入する空気の流れについて説明する。図６は、図５のVI−VI線における断面図であって、折り畳み姿勢にあるときの後部座席３の断面図である。背もたれ１３は、背もたれ本体３６と、背もたれ本体３６の外周を覆うシートカバー３５を備えている。上記の貫通孔３２ａは、背もたれ本体３６の肩部３４に設けられている。また、上記のメッシュ布３１ａ、３３ａは、シートカバー３５の一部である。なお、図６では、メッシュ布３１ａ、３３ａの断面を示すハッチングを省略する。一方、座部１４は、座部本体４６と、座部本体４６の裏面以外の外周を覆うシートカバー４５を備えている。上記の溝４１ａは、座部本体４６の裏面に設けられている。溝４１ａは、背もたれ１３の肩部３４の最大幅よりも長く延びており、溝４１ａは、後部座席３が折り畳み姿勢である場合に、背もたれ１３の裏面３１から表面３３に亘って延びている。   With reference to FIG. 6, the flow of air flowing into the vent hole 63a in the folded posture will be described. FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 5, and is a cross-sectional view of the rear seat 3 when in the folded position. The backrest 13 includes a backrest body 36 and a seat cover 35 that covers the outer periphery of the backrest body 36. The through hole 32 a is provided in the shoulder portion 34 of the backrest body 36. The mesh cloths 31 a and 33 a are part of the seat cover 35. In addition, in FIG. 6, the hatching which shows the cross section of the mesh cloth 31a and 33a is abbreviate | omitted. On the other hand, the seat portion 14 includes a seat portion main body 46 and a seat cover 45 that covers an outer periphery other than the back surface of the seat portion main body 46. The groove 41 a is provided on the back surface of the seat body 46. The groove 41 a extends longer than the maximum width of the shoulder portion 34 of the backrest 13, and the groove 41 a extends from the back surface 31 of the backrest 13 to the front surface 33 when the rear seat 3 is in the folded posture.

図６に示すように、折り畳み姿勢では、背もたれ１３の肩部３４が座部１４の裏面４１に接し、バッテリ６の前方の空間Ｓ１は、座部１４の裏面４１及び背もたれ１３の肩部３４により覆われている。ここで、通風口６３ａと連通する空間Ｓ１は、貫通孔３２ａ及びメッシュ布３１ａ、３３ａを介して、背もたれ１３の上方の空間Ｓ２と連通している。別言すれば、背もたれ１３に、後部座席３が折り畳み姿勢であるときに空間Ｓ２と通風口６３ａを連通する貫通孔３２ａが設けられている。さらに、空間Ｓ１は、溝４１ａを介して、空間Ｓ２と連通している。別言すれば、座部１４の裏面４１に、後部座席３が折り畳み姿勢であるときに空間Ｓ２と通風口６３ａを連通する溝４１ａが設けられている。   As shown in FIG. 6, in the folded posture, the shoulder portion 34 of the backrest 13 is in contact with the back surface 41 of the seat portion 14, and the space S1 in front of the battery 6 is defined by the back surface 41 of the seat portion 14 and the shoulder portion 34 of the backrest 13. Covered. Here, the space S1 communicating with the vent hole 63a communicates with the space S2 above the backrest 13 through the through hole 32a and the mesh cloths 31a and 33a. In other words, the backrest 13 is provided with a through hole 32a that communicates the space S2 and the vent hole 63a when the rear seat 3 is in the folded posture. Furthermore, the space S1 communicates with the space S2 through the groove 41a. In other words, the back surface 41 of the seat portion 14 is provided with a groove 41a that communicates the space S2 and the vent hole 63a when the rear seat 3 is in the folded posture.

図６の太線矢印は、空気の流れを示す。太線矢印に示すように、空間Ｓ２の空気は、溝４１ａ及び貫通孔３２ａを介して、空間Ｓ１に流れ込む。そして、空間Ｓ１に流れ込んだ空気は、通風口６３ａを介して、バッテリケース６１内に流れ込む。この流れ込んだ空気により、バッテリケース６１に収容されているバッテリ本体６２が冷却される。このように、後部座席３が折り畳み姿勢であるときでも、空間Ｓ２の空気が溝４１ａ及び貫通孔３２ａを介して通風口６３ａから流れ込むので、通風口６３ａから十分に空気を取り込むことができ、バッテリ本体６２を冷却することができる。   The bold arrows in FIG. 6 indicate the air flow. As indicated by the thick arrow, the air in the space S2 flows into the space S1 through the groove 41a and the through hole 32a. Then, the air that has flowed into the space S1 flows into the battery case 61 via the vent hole 63a. The battery main body 62 accommodated in the battery case 61 is cooled by the air that has flowed in. Thus, even when the rear seat 3 is in the folded position, the air in the space S2 flows from the ventilation port 63a through the groove 41a and the through hole 32a, so that the air can be sufficiently taken in from the ventilation port 63a. The main body 62 can be cooled.

以下、実施例で示した技術に関する留意点を述べる。溝４１ａ−４１ｃ及び貫通孔３２ａ、３２ｂが、請求項の「通風通路」の一例である。ここで、座部１４の裏面４１に設けられる溝は、３本に限らない。少なくとも１本の溝が設けられていればよい。また、背もたれ１３に設けられる貫通孔は、２個に限らない。少なくとも１個の貫通孔が設けられていればよい。   Hereinafter, points to be noted regarding the technology shown in the embodiments will be described. The grooves 41a to 41c and the through holes 32a and 32b are examples of the “ventilation passage” in the claims. Here, the number of grooves provided on the back surface 41 of the seat portion 14 is not limited to three. It is sufficient that at least one groove is provided. Further, the number of through holes provided in the backrest 13 is not limited to two. It is sufficient that at least one through hole is provided.

また、座部１４の裏面４１に溝４１ａ−４１ｃが設けられ、背もたれ１３に貫通孔３２ａ、３２ｂが設けられなくてもよい。反対に、背もたれ１３に貫通孔３２ａ、３２ｂが設けられ、座部１４の裏面４１に溝４１ａ−４１ｃが設けられなくてもよい。即ち、座部１４の裏面４１と背もたれ１３の少なくとも一方に、後部座席３が折り畳み姿勢にあるときに背もたれ１３の上方の空間Ｓ２と通風口６３ａを連通する通風通路が設けられていればよい。   Further, the grooves 41 a to 41 c are provided on the back surface 41 of the seat portion 14, and the through holes 32 a and 32 b may not be provided on the backrest 13.
