Description

車両の高電圧部品の保護構造Protective structure for vehicle high voltage components
　本発明は、車両の高電圧部品の保護構造に関する。 The present invention relates to a protection structure for high voltage components of a vehicle.
　車室（キャビン）に設けられた座席の後方の空間を利用してバッテリーやＤＣ／ＤＣコンバータなどの高電圧部品を配置した車両が提供されている。
　この場合、車両が後面衝突すると、高電圧部品に対して座席および車両後部に位置する周辺部品が干渉するおそれがあるため、高電圧部品の保護を図る必要がある。
　そこで、高電圧部品を強度剛性の高い材料から構成されたケース内に収容する構造が提案されている（特許文献１参照）。
　また、座席と高電圧部品との間に、衝突時に後方に移動する座席に当接して座席の移動を止める上メンバを設けると共に、高電圧部品と車両後部に位置するエンジンとの間に、衝突時に前方に移動するエンジンに当接してエンジンの移動を止める下メンバを設ける構造が提案されている（特許文献２参照）。 2. Description of the Related Art Vehicles are provided in which high-voltage components such as batteries and DC/DC converters are arranged using a space behind a seat provided in a vehicle interior (cabin).
In this case, if the vehicle collides from the rear, there is a risk that the high-voltage components will interfere with the seat and peripheral components located at the rear of the vehicle, so it is necessary to protect the high-voltage components.
Therefore, a structure has been proposed in which high-voltage components are housed in a case made of a material with high strength and rigidity (see Patent Document 1).
In addition, an upper member is provided between the seat and the high-voltage parts to stop the seat from moving backwards in the event of a collision, and an upper member is provided between the high-voltage parts and the engine located at the rear of the vehicle. A structure has been proposed in which a lower member is provided, which stops the movement of the engine by coming into contact with the engine that moves forward at times (see Patent Document 2).

　しかしながら、特許文献１記載の技術では、高電圧部品の全体を覆う強度剛性の高い専用のケースを設ける必要がある。
　また、特許文献２記載の技術では、座席とエンジンとの間に、上メンバと下メンバを設置するに足る大きな占有スペースを確保しなくてはならない不利がある。
　さらに双方の技術では、後面衝突時に、高電圧部品の車両前方に位置する座席の骨格と周辺部品とで挟まれることに対する高電圧部品の保護が何ら図られていない。
　本発明は、上記事情に鑑みなされたものであり、後面衝突時における車両前方に位置する座席の骨格に対する高電圧部品の保護を図りつつ、占有スペースのコンパクト化を図る上で有利な車両の高電圧部品の保護構造を提供することを目的とする。 However, with the technique described in Patent Document 1, it is necessary to provide a dedicated case with high strength and rigidity that covers the entire high voltage component.
Further, the technique described in Patent Document 2 has the disadvantage that a large enough space for installing the upper member and the lower member must be secured between the seat and the engine.
Furthermore, both techniques do not provide any protection for the high-voltage component from being pinched between the frame of the seat located at the front of the vehicle and surrounding components in the event of a rear-end collision.
The present invention has been made in view of the above circumstances, and is designed to improve the height of the vehicle, which is advantageous in reducing the space occupied while protecting high-voltage components on the frame of the seat located at the front of the vehicle in the event of a rear-end collision. The purpose is to provide a protective structure for voltage components.
　上記目的を達成するために、本発明の一実施の形態は、座席と、前記座席直後のフロアパネル上にカバーで覆われた高電圧部品が設けられた車両の高電圧部品の保護構造であって、前記カバーの内部に前記フロアパネルに取り付けられた保護フレームが設けられ、前記保護フレームは、車幅方向に延在して前記高電圧部品を後方から覆う正面部と、前記正面部の延在方向の両端から車両前方に延在し前記座席の骨格部材に正対する一対の側面部とを備えていることを特徴とする。 In order to achieve the above object, an embodiment of the present invention provides a protection structure for high voltage components of a vehicle, in which a seat and a high voltage component covered with a cover are provided on a floor panel immediately behind the seat. A protection frame attached to the floor panel is provided inside the cover, and the protection frame includes a front part that extends in the vehicle width direction and covers the high voltage component from the rear, and an extension of the front part. The seat is characterized by comprising a pair of side surfaces extending toward the front of the vehicle from both ends in the seat direction and directly facing the frame member of the seat.
　本発明の一実施の形態によれば、後面衝突時に、高電圧部品が周辺部品と座席の骨格部材との間で挟まれようとした際に、保護フレームにより高電圧部品を保護する上で有利となる。
　保護フレームはカバーの内部に配置されるコンパクトな部材であるため、保護フレームを小さなスペースに配置できる。 According to an embodiment of the present invention, when a high voltage component is about to be pinched between peripheral components and a seat frame member during a rear collision, the protective frame is advantageous in protecting the high voltage component. becomes.
Since the protective frame is a compact member placed inside the cover, the protective frame can be placed in a small space.
