Description

この発明は車両の電気機器固定構造に係り、特に車両後方から衝突されたときに対応するために、電気機器固定部の取付固定部の剛性を支持部よりも高く形成し、支持部のみを変形させて電気機器が破損されるのを防止する車両の電気機器固定構造に関するものである。   The present invention relates to a structure for fixing an electric device of a vehicle, and in particular, in order to cope with a collision from the rear of the vehicle, the mounting fixing portion of the electric device fixing portion has a higher rigidity than the supporting portion, and only the supporting portion is deformed. The present invention relates to an electric equipment fixing structure for a vehicle that prevents the electric equipment from being damaged.

車両としては、内燃機関を搭載するガソリンエンジン車両以外にも、内燃機関とバッテリとを搭載するハイブリッド車両や、バッテリを搭載する電気自動車等がある。   As a vehicle, in addition to a gasoline engine vehicle equipped with an internal combustion engine, there are a hybrid vehicle equipped with an internal combustion engine and a battery, an electric vehicle equipped with a battery, and the like.

そして、ハイブリッド車両、電気自動車等のモータをパワートレインとして使用する車両においては、モータを駆動するために、バッテリやインバータ等の部品を必要としている。   And in vehicles which use motors, such as a hybrid vehicle and an electric car, as a power train, parts, such as a battery and an inverter, are needed in order to drive a motor.

ところで、従来の車両において、車両自体が小さい場合には、前記部品を搭載するスペースに限りがあり、特にハイブリッド車両においては、高電圧系システムを構成するバッテリやインバータ等の部品以外に、既存のエンジン部品もあるため、搭載スペースの確保が特に限られてくる。   By the way, in the conventional vehicle, when the vehicle itself is small, the space for mounting the parts is limited, and particularly in the hybrid vehicle, in addition to the parts such as the battery and the inverter constituting the high voltage system, Since there are also engine parts, securing the mounting space is particularly limited.

そして、軽自動車タイプのハイブリッド車両１０２の場合は、図７及び図８に示す如く、従来の後部座席１０３が配置される場所にインバータやバッテリ等の電気機器１１０を搭載することがあるが、この場合、搭載スペースが小さいために、インバータやバッテリ等の電気機器１１０の搭載を後部車軸１１１より前方のみで納めることが困難である。   In the case of a light vehicle type hybrid vehicle 102, as shown in FIGS. 7 and 8, an electric device 110 such as an inverter or a battery may be mounted at a place where the conventional rear seat 103 is disposed. In this case, since the mounting space is small, it is difficult to store the electric device 110 such as an inverter or a battery only in front of the rear axle 111.

このため、図７及び図８に示す如く、リアパネル１０６近傍までバッテリやインバータ等の電気機器１１０をギリギリに配置することがある。   For this reason, as shown in FIGS. 7 and 8, an electric device 110 such as a battery or an inverter may be arranged in the last minute until the vicinity of the rear panel 106.

ところが、軽自動車、特に後部にトランクルームを有していない車両１０２においては、図８に示す如く、後面衝突時に後部車軸１１１または後部ホイール１１３付近までリヤパネル１０６が押されて変形することがあるので、この場所にインバータや電池等の電気機器１１０を配置すると、損傷により高電圧系システムが停止する場合があるという不都合がある。   However, in a light vehicle, particularly a vehicle 102 that does not have a trunk room at the rear, as shown in FIG. If the electric device 110 such as an inverter or a battery is disposed in this place, there is a disadvantage that the high voltage system may stop due to damage.

そこで、この発明は、上述不都合を除去するために、車両のシートより後部のフロアに車両駆動用電気機器を搭載した車両の電気機器固定構造において、車両幅方向において中央部分に形成された凹部と、この凹部両側に形成されサイドパネルに連結される両端部とから構成された後部フロアを設け、前記電気機器は、前記凹部に固定されるブラケットに固定されるとともに、このブラケットは、はしご形状を備えたラダー部と、電気機器固定部とから構成され、この電気機器固定部は、前記電気機器と直接接し、かつ固定部材により電気機器を固定している取付固定部と、前記電気機器とは取付時において直接接触していない支持部とから構成され、前記電気機器が固定された状態では前記取付固定部の剛性は前記支持部よりも高く形成したことを特徴とする。   Accordingly, in order to eliminate the above-described disadvantages, the present invention provides a vehicle electrical device fixing structure in which a vehicle drive electrical device is mounted on the floor behind the vehicle seat, and a recess formed in the central portion in the vehicle width direction. A rear floor formed from both ends formed on both sides of the recess and connected to the side panel, and the electric device is fixed to a bracket fixed to the recess, and the bracket has a ladder shape The electric device fixing portion includes a ladder portion provided and an electric device fixing portion, and the electric device fixing portion is in direct contact with the electric device and is fixed to the electric device by a fixing member. And a support portion that is not in direct contact during mounting, and in a state where the electric device is fixed, the rigidity of the mounting fixing portion is higher than that of the support portion. It is characterized in.

以上詳細に説明した如くこの本発明によれば、車両のシートより後部のフロアに車両駆動用電気機器を搭載した車両の電気機器固定構造において、車両幅方向において中央部分に形成された凹部と、凹部両側に形成されサイドパネルに連結される両端部とから構成された後部フロアを設け、電気機器は、凹部に固定されるブラケットに固定されるとともに、このブラケットは、はしご形状を備えたラダー部と、電気機器固定部とから構成され、電気機器固定部は、電気機器と直接接し、かつ固定部材により電気機器を固定している取付固定部と、電気機器とは取付時において直接接触していない支持部とから構成され、前記電気機器が固定された状態では取付固定部の剛性は支持部よりも高く形成したので、車両後方から衝突されたときにおいて、前記電気機器の固定された取付固定部は剛性が高いため、電気機器が破損されることがなく、衝突後も電気機器が再使用可能となるものである。   As described in detail above, according to the present invention, in the vehicle electrical equipment fixing structure in which the vehicle drive electrical equipment is mounted on the floor behind the vehicle seat, a recess formed in the central portion in the vehicle width direction; A rear floor composed of both ends formed on both sides of the recess and connected to the side panel is provided, and the electrical device is fixed to a bracket fixed to the recess, and the bracket is a ladder portion having a ladder shape. And the electric equipment fixing portion, the electric equipment fixing portion is in direct contact with the electric equipment and the electric equipment is in direct contact with the mounting fixing portion that fixes the electric equipment by the fixing member. In the state where the electric device is fixed, the mounting and fixing portion has a higher rigidity than the supporting portion. Te, fixed fixing lug of the electrical equipment for high rigidity, without electrical device is damaged, in which after the collision also has electric device becomes reusable.

上述の如く発明したことにより、車両後方から衝突されたときにおいては、電気機器の固定された取付固定部は支持部よりも剛性が高いため、支持部のみが衝突時のエネルギを吸収して変形し、電気機器が破損されることがない。   As a result of the invention as described above, when the vehicle is collided from behind, the mounting and fixing portion to which the electric device is fixed has higher rigidity than the support portion. The electrical equipment will not be damaged.

Standing portions 22a-2, 22b- 22c-2, and in the left and right side fixing members 22a and the right side fixing member (not shown) flat plate portion 22a-1 of the fixing member 22 at a plurality of locations, for example, two locations. Then, the electric device 10 is fixed to the mounting fixing portion 24 of the electric device fixing portion 20.

更にまた、前記電気機器固定部２０は、図３及び図４に示す如く、２枚の側板３８−１、３８−２と、これらの側板３８−１、３８−２の上端を連絡する平板状の上板３８−３とにより、断面コ字状に形成される。   Furthermore, as shown in FIGS. 3 and 4, the electric equipment fixing portion 20 is a flat plate shape that connects two side plates 38-1 and 38-2 and the upper ends of these side plates 38-1 and 38-2. The upper plate 38-3 is formed in a U-shaped cross section.

そして、２枚の側板３８−１、３８−２には、図３に示す如く、車両後方に指向するに従い下側寸法を漸次減少させた傾斜部４０−１が形成されるとともに、車両前側に側板用切除孔部４０−２が形成される。   In addition, as shown in FIG. 3, the two side plates 38-1 and 38-2 are formed with an inclined portion 40-1 in which the lower dimension is gradually reduced as it is directed toward the rear of the vehicle, and on the front side of the vehicle. A side plate excision hole 40-2 is formed.

このとき、前記電気機器固定部２０の２枚の側板３８−１、３８−２の傾斜部４０−１を、図５に示す如く、前記電気機器固定部２０に固定された前記電気機器１０よりも車両後方側へ突出させる。   At this time, as shown in FIG. 5, the inclined portions 40-1 of the two side plates 38-1 and 38-2 of the electric device fixing portion 20 are fixed by the electric device 10 fixed to the electric device fixing portion 20. Project to the rear side of the vehicle.

また、前記電気機器固定部２０の上板３８−３は、図４に示す如く、２枚の側板３８−１、３８−２の上端を連絡すべく矩形状に形成され、中央部位に切除孔部４２を形成する。   Further, as shown in FIG. 4, the upper plate 38-3 of the electric device fixing portion 20 is formed in a rectangular shape so as to connect the upper ends of the two side plates 38-1 and 38-2, and a cut hole is formed in the central portion.

このとき、前記側板３８−１、３８−２の側板用切除孔部４０−２の形成位置に対して、上板３８−３の切除孔部４２の形成位置を車両後方側とする。   At this time, the formation position of the excision hole portion 42 of the upper plate 38-3 is the vehicle rear side with respect to the formation position of the excavation hole portion 40-2 for the side plate of the side plates 38-1 and 38-2.

そして、前記固定部材２２を前記取付固定部２４を構成する上板３８−３に固定して前記取付固定部２４の剛性を高める。側板３８−１、３８−２に側板用切除孔部４０−２を形成するとともに、上板３８−３に切除孔部４２を形成して前記取付固定部２４を構成する部分以外すなわち前記支持部２６の剛性を低下させている。これにより、取付固定部２４の剛性は、前記支持部２６よりも高く形成されることとなる。   And the said fixing member 22 is fixed to the upper board 38-3 which comprises the said mounting fixing part 24, and the rigidity of the said mounting fixing part 24 is improved. The side plate 38-1, 38-2 is formed with a side plate excision hole 40-2, and the upper plate 38-3 is formed with an excision hole 42 to constitute the mounting fixing portion 24, that is, the support portion. 26 is reduced in rigidity. Thereby, the rigidity of the attachment fixing part 24 is formed higher than the support part 26.

次に作用を説明する。   Next, the operation will be described.

前記車両２の後部フロア８において、従来、スペアタイヤの収納される場所、つまり凹部１２に前記電気機器１０を搭載する際には、図１及び図２に示す如く、前記ブラケット１６を後部フロア８の凹部１２に固定し、ブラケット１６の電気機器固定部２０に電気機器１０を固定する。   Conventionally, when the electric device 10 is mounted on the rear floor 8 of the vehicle 2 where a spare tire is stored, that is, in the recess 12, the bracket 16 is attached to the rear floor 8 as shown in FIGS. And the electric device 10 is fixed to the electric device fixing portion 20 of the bracket 16.

つまり、ブラケット１６のラダー部１８を構成する第１、第２部材２８−１、２８−２の後端に、図１及び図２に示す如く、第２連結部３２−２及び第４連結部３２−４を介して、電気機器固定部２０を取り付ける。   That is, at the rear ends of the first and second members 28-1 and 28-2 constituting the ladder portion 18 of the bracket 16, as shown in FIGS. 1 and 2, the second connecting portion 32-2 and the fourth connecting portion. The electric equipment fixing | fixed part 20 is attached via 32-4.

そして、この電気機器固定部２０は、取付固定部２４と前記支持部２６とから構成され、図１及び図４に示す如く、固定部材２２により電気機器１０を電気機器固定部２０の取付固定部２４に固定する。   And this electric equipment fixing | fixed part 20 is comprised from the attachment fixing | fixed part 24 and the said support part 26, and as shown in FIG.1 and FIG.4, the electric equipment 10 is attached to the electric equipment fixing | fixed part 20 of the electric equipment fixing | fixed part 20 by the fixing member 22. 24.

前記車両２の後方からの後面衝突時には、図５に示す状態に搭載される電気機器１０が、図６に示す如く、リヤパネル６の変形によって車両前方に移動する。   At the time of a rear collision from the rear of the vehicle 2, the electric device 10 mounted in the state shown in FIG. 5 moves forward of the vehicle by deformation of the rear panel 6, as shown in FIG.

すなわち、前記取付固定部２４に固定部材２２を固定して前記取付固定部２４には固定部材２２が固定されているので、前記取付固定部２４の剛性を高めることができる。さらに、側板３８−１、３８−２に側板用切除孔部４０−２を形成して前記支持部２６の剛性を低下させたことにより、後面衝突時にリヤパネル６が変形して前記電気機器１０が車両前方に移動する際には、図６に示す如く、前記支持部２６後端にリヤパネル６が接触し、支持部２６が衝突時のエネルギを吸収して２枚の側板３８−１、３８−２部分に変形が生ずるが、剛性を高めた前記取付固定部２４は変形しないため、リヤパネル６と電気機器１０との間隙は維持されたまま、前記電気機器１０が単に車両前方にスライド移動することとなる。   That is, since the fixing member 22 is fixed to the mounting fixing portion 24 and the fixing member 22 is fixed to the mounting fixing portion 24, the rigidity of the mounting fixing portion 24 can be increased. Further, by forming the side plate excision hole portion 40-2 in the side plates 38-1 and 38-2 to reduce the rigidity of the support portion 26, the rear panel 6 is deformed at the time of a rear collision, and the electric device 10 is When moving forward of the vehicle, as shown in FIG. 6, the rear panel 6 comes into contact with the rear end of the support portion 26, and the support portion 26 absorbs the energy at the time of the collision and the two side plates 38-1, 38- Although the two portions are deformed, the mounting and fixing portion 24 with increased rigidity is not deformed, so that the electric device 10 simply slides forward of the vehicle while the gap between the rear panel 6 and the electric device 10 is maintained. It becomes.

なお、前記支持部２６の２枚の側板３８−１、３８−２における変形は、例えば図３に斜線部分で示す如く、側板用切除孔部４０−２の上部且つ車両前方向側と、側板用切除孔部４０−２の下部且つ車両後方向側の傾斜部４０−１下端との剛性の低下する部位に発生する。   The two side plates 38-1 and 38-2 of the support portion 26 are deformed, for example, as shown by the hatched portion in FIG. It occurs in a portion where the rigidity is lowered with the lower end of the cutting hole 40-2 and the lower end of the inclined portion 40-1 on the vehicle rear side.

これにより、前記ブラケット１６をはしご形状を備えたラダー部１８と電気機器固定部２０とから構成し、この電気機器固定部２０を、前記電気機器１０と直接接し、かつ固定部材２２により電気機器１０を固定している取付固定部２４と、前記電気機器１０とは取付時において直接接触していない支持部２６とから構成し、前記電気機器１０が固定された状態では前記取付固定部２４の剛性を前記支持部２６よりも高く形成したことによって、車両後方から衝突されたときにおいて、前記電気機器１０の固定された取付固定部２４は剛性が高いため、電気機器１０が破損されることがなく、衝突後も電気機器１０が再使用可能となり、実用上有利である。   As a result, the bracket 16 includes a ladder portion 18 having a ladder shape and an electric device fixing portion 20. The electric device fixing portion 20 is in direct contact with the electric device 10 and is fixed by the fixing member 22. And a support portion 26 that is not in direct contact with the electric device 10 when the electric device 10 is fixed. When the electric device 10 is fixed, the rigidity of the mounting fixing portion 24 is fixed. Since the mounting fixing portion 24 to which the electric device 10 is fixed has high rigidity when the vehicle is collided from behind the vehicle, the electric device 10 is not damaged. The electric device 10 can be reused after the collision, which is practically advantageous.

また、前記電気機器固定部２０は、取付固定部２４と支持部２６とを有しているとともに、固定された前記電気機器１０より車両後方側へ突出した形状を備えていることにより、車両後方から衝突された場合においても、変形したリヤパネル６が電気機器１０よりも先に電気機器固定部２０に接触し、支持部２６が変形しながらエネルギを吸収するため、電気機器１０が破損されるのを確実に防止し得る。   In addition, the electric device fixing portion 20 includes a mounting fixing portion 24 and a support portion 26, and has a shape protruding toward the vehicle rear side from the fixed electric device 10. Even in the case of collision, the deformed rear panel 6 contacts the electric device fixing part 20 before the electric device 10, and the support portion 26 absorbs energy while deforming, so that the electric device 10 is damaged. Can be surely prevented.
