Description

本開示は、電池パックに関する。 The present disclosure relates to battery packs.

たとえば、特開２０１３−８９４４８号公報（以下、「特許文献１」という。）には、複数の二次電池からなる電池モジュールを車両に搭載するための構造体が開示されている。構造体は、電池モジュールを固定するための下枠体と、電池モジュールの上部を覆う上枠体と、を有している。下枠体及び上枠体は、電池モジュールを覆う形状を有している。このため、車両の衝突時等における衝撃が構造体で受けられる。よって、前記衝撃が電池モジュールに伝わるのが抑制される。 For example, Japanese Patent Laying-Open No. 2013-89448 (hereinafter referred to as "Patent Document 1") discloses a structure for mounting a battery module including a plurality of secondary batteries in a vehicle. The structure has a lower frame for fixing the battery module and an upper frame for covering the upper part of the battery module. The lower frame body and the upper frame body have a shape that covers the battery module. Therefore, the structure receives a shock when the vehicle collides. Therefore, the impact is suppressed from being transmitted to the battery module.

特開２０１３−８９４４８号公報JP, 2013-89448, A

特許文献１に記載される構造体は、車両の衝突時等における衝撃が電池モジュールに伝わるのを抑制するため、高い強度が求められる。このような構造体を鋼材で製造すると、構造体の重量が大きくなり、一方、軽量化のために、構造体をアルミニウムで製造すると、コストが高くなる。 The structure described in Patent Document 1 is required to have high strength in order to suppress the impact transmitted to the battery module during a vehicle collision or the like. If such a structure is manufactured from a steel material, the weight of the structure is increased, while if the structure is manufactured from aluminum for weight reduction, the cost is increased.

本開示の目的は、著しい重量増及びコスト増を回避しながら、衝撃が二次電池に伝わるのを抑制することが可能な電池パックを提供することである。 An object of the present disclosure is to provide a battery pack capable of suppressing an impact from being transmitted to a secondary battery while avoiding a significant increase in weight and cost.

本開示に従った電池パックは、複数の二次電池と、金属からなり、前記複数の二次電池を収容する電池ケースと、絶縁材料からなり、前記電池ケース内に配置された方向変更部材と、を備える。前記二次電池は、容器と、前記容器から突出する形状を有する正極端子と、前記容器から突出する形状を有する負極端子と、前記正極端子又は前記負極端子から前記電池ケースに向かって突出する形状を有する活電部と、を有する。前記方向変更部材は、前記活電部と前記電池ケースとの間に配置されている。前記活電部は、前記正極端子又は前記負極端子に接続されている側の端部である基端部と、前記基端部と反対側の端部である先端部と、を有する。前記方向変更部材は、前記活電部に向かって前記電池ケースとともに変位したときに前記活電部の前記先端部と接触することにより、前記基端部と前記先端部とを結ぶ方向が前記方向変更部材が前記活電部に接触する前における前記基端部と前記先端部とを結ぶ方向と交差するように前記活電部を屈曲させる。 A battery pack according to the present disclosure includes a plurality of secondary batteries, a battery case that is made of metal and houses the plurality of secondary batteries, and an insulating material, and a direction changing member that is arranged in the battery case. , Is provided. The secondary battery includes a container, a positive electrode terminal having a shape protruding from the container, a negative electrode terminal having a shape protruding from the container, and a shape protruding from the positive electrode terminal or the negative electrode terminal toward the battery case. And a live part having. The direction changing member is arranged between the live part and the battery case. The live part has a base end that is an end connected to the positive electrode terminal or the negative electrode terminal, and a tip that is an end opposite to the base end. The direction changing member comes into contact with the distal end of the live part when displaced together with the battery case toward the live part, so that the direction connecting the proximal end and the distal end is the direction. The live part is bent so as to intersect the direction connecting the base end part and the front end part before the changing member comes into contact with the live part.

本電池パックでは、方向変更部材が活電部に向かって変位したときに当該方向変更部材が活電部の先端部に接触することにより、活電部の先端部と基端部とを結ぶ方向が、方向変更部材が活電部に接触する前における基端部と先端部とを結ぶ方向と交差するように活電部が屈曲するため、電池ケースと活電部との接触が抑制される。よって、この電池パックでは、著しい重量増及びコスト増を回避することと、車両の衝突時等における衝撃が二次電池に伝わるのを抑制することと、の双方が達成される。 In the battery pack, when the direction changing member is displaced toward the live part, the direction changing member comes into contact with the leading end of the live part, thereby connecting the leading end and the base end of the live part. However, since the live part is bent so as to intersect with the direction connecting the base end part and the tip part before the direction changing member contacts the live part, contact between the battery case and the live part is suppressed. .. Therefore, in this battery pack, both significant increase in weight and cost increase and suppression of transmission of impact to the secondary battery at the time of collision of the vehicle are achieved.

以上に説明したように、本開示によれば、著しい重量増及びコスト増を回避しながら、衝撃が二次電池に伝わるのを抑制することが可能な電池パックを提供することができる。 As described above, according to the present disclosure, it is possible to provide a battery pack capable of suppressing the transmission of impact to the secondary battery while avoiding a significant increase in weight and cost.

方向変更部材３０は、電池ケース２０内に配置されている。具体的に、方向変更部材３０は、活電部（総正極端子板１４、総負極端子板１５）と電池ケース２０の側板２４との間に配置されている。方向変更部材３０は、容器１１の上方に配置されている。方向変更部材３０は、絶縁材料からなる。 The direction changing member 30 is arranged in the battery case 20. Specifically, the direction changing member 30 is arranged between the live part (total positive electrode terminal plate 14, total negative electrode terminal plate 15) and the side plate 24 of the battery case 20. The direction changing member 30 is arranged above the container 11. The direction changing member 30 is made of an insulating material.

図２は、活電部を構成する総正極端子板と方向変更部材との関係を概略的に示す断面図である。以下、図２を参照しながら、方向変更部材３０について説明する。 FIG. 2 is a cross-sectional view schematically showing the relationship between the total positive electrode terminal plate and the direction changing member that form the live part. Hereinafter, the direction changing member 30 will be described with reference to FIG.

方向変更部材３０は、総正極端子板１４に向かって側板２４とともに変位したときに総正極端子板１４の先端部１４ｂと接触することにより、基端部１４ａと先端部１４ｂとを結ぶ方向が方向変更部材３０が総正極端子板１４に接触する前における基端部１４ａと先端部１４ｂとを結ぶ方向（図２における左右方向）と交差するように総正極端子板１４を屈曲させる。より詳細には、方向変更部材３０は、総正極端子板１４が容器１１の側面１１Ｓよりも容器１１の幅方向における内側に収まる形状となるように総正極端子板１４を屈曲させる。方向変更部材３０は、総正極端子板１４の先端部１４ｂと対向する対向面３２を有している。対向面３２は、総正極端子板１４の先端部１４ｂから離間するにしたがって次第に上方に向かう形状を有している。本実施形態では、対向面３２は、総正極端子板１４の先端部１４ｂから離間するにしたがって次第に上方に向かうように傾斜する形状を有している。 The direction changing member 30 comes into contact with the distal end portion 14b of the total positive electrode terminal plate 14 when displaced together with the side plate 24 toward the total positive electrode terminal plate 14, so that the direction connecting the base end portion 14a and the distal end portion 14b is the direction. The total positive electrode terminal plate 14 is bent so as to intersect the direction (the left-right direction in FIG. 2) connecting the base end portion 14a and the front end portion 14b before the changing member 30 contacts the total positive electrode terminal plate 14. More specifically, the direction changing member 30 bends the total positive electrode terminal plate 14 so that the total positive electrode terminal plate 14 has a shape to fit inside the side surface 11S of the container 11 in the width direction of the container 11. The direction changing member 30 has a facing surface 32 that faces the tip portion 14 b of the total positive electrode terminal plate 14. The facing surface 32 has a shape that gradually extends upward as it is separated from the tip portion 14 b of the total positive electrode terminal plate 14. In the present embodiment, the facing surface 32 has a shape that gradually inclines upward as it is separated from the tip portion 14 b of the total positive electrode terminal plate 14.

このため、車両の衝突時等における衝撃が電池ケース２０の側板２４に作用することによって側板２４が二次電池１０に向かう方向に変位した際、方向変更部材３０の対向面３２が総正極端子板１４の先端部１４ｂに接触した後そのまま基端部１４ａに向かって変位することにより、図２において二点鎖線で示されるように、総正極端子板１４は、先端部１４ｂが対向面３２を摺動しながら上方に向かうように屈曲する。これにより、総正極端子板１４は、容器１１の側面１１Ｓよりも容器１１の幅方向における内側に収まる形状となる。その結果、側板２４が容器１１の側面１１Ｓに接触するため、前記衝撃を二次電池１０全体で受けることが可能となる。 Therefore, when the side plate 24 of the battery case 20 is displaced in the direction toward the secondary battery 10 due to the impact applied to the side plate 24 of the battery case 20 when the vehicle collides, the facing surface 32 of the direction changing member 30 has the entire positive electrode terminal plate. As shown by the chain double-dashed line in FIG. 2, the tip portion 14b of the total positive electrode terminal plate 14 slides on the facing surface 32 by contacting the tip portion 14b of 14 and then displacing it toward the base portion 14a. Bend upward while moving. As a result, the total positive electrode terminal plate 14 has a shape that can fit inside the side surface 11S of the container 11 in the width direction of the container 11. As a result, since the side plate 24 contacts the side surface 11S of the container 11, the impact can be received by the entire secondary battery 10.

以上に説明したように、本実施形態の電池パック１では、方向変更部材３０が活電部（総正極端子板１４、総負極端子板１５）に向かって変位したときに当該活電部の先端部に接触することにより、活電部の先端部と基端部とを結ぶ方向が、方向変更部材３０が活電部に接触する前における基端部と先端部とを結ぶ方向と交差するように活電部が屈曲するため、電池ケース２０と活電部との接触が抑制される。よって、電池パック１では、著しい重量増及びコスト増を回避することと、車両の衝突時等における衝撃が二次電池１０に伝わるのを抑制することと、の双方が達成される。 As described above, in the battery pack 1 of the present embodiment, when the direction changing member 30 is displaced toward the live part (total positive electrode terminal plate 14, total negative electrode terminal plate 15), the tip of the active part is moved. By contacting the live part, the direction connecting the distal end and the base end of the live part may intersect the direction connecting the base end and the front end before the direction changing member 30 contacts the live part. Since the live part is bent, contact between the battery case 20 and the live part is suppressed. Therefore, in the battery pack 1, both a significant increase in weight and a cost increase are prevented, and an impact at the time of a vehicle collision or the like is suppressed from being transmitted to the secondary battery 10.

なお、今回開示された実施形態はすべての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 It should be understood that the embodiments disclosed this time are exemplifications in all respects and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

例えば、方向変更部材３０の対向面３２は、当該対向面３２が活電部に接触した際に活電部の先端部が下方や側方（複数の二次電池１０が互いに隣接する方向）に向かうように当該活電部を屈曲させる形状に形成されてもよい。 For example, in the facing surface 32 of the direction changing member 30, when the facing surface 32 comes into contact with the live part, the tip of the live part is directed downward or laterally (direction in which the plurality of secondary batteries 10 are adjacent to each other). It may be formed in a shape in which the live part is bent so as to face.
