이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2에는 본 발명의 1실시예에 따라 고압전장부품케이스가 차체에 장착된 상태의 단면이 도시되어 있는 바, 즉 리어 시트(10)의 후방에 고압전장부품(11)이 수납된 케이스(12)가 리어 플로워 패널(13)에 안착된 상태에서 다수개의 볼트를 매개로 체결되어 장착된다.FIG. 2 is a cross-sectional view of a state in which the high-voltage electric component case is mounted on the vehicle body according to an embodiment of the present invention, that is, the case 12 in which the high-voltage electric component 11 is accommodated in the rear of the rear seat 10. ) Is mounted on the rear floor panel 13 by being fastened through a plurality of bolts.

상기 케이스(12)는 대체로 평행 사변형 형상을 이루고서 그 저면의 전체가 리어 플로워 패널(13)에 안착되어 도 3에 자세히 도시된 바와 같이 6개의 볼트를 매개로 체결되어 지지된다.The case 12 has a generally parallelogram shape, and the entire bottom surface thereof is seated on the rear follower panel 13, and is supported by being fastened through six bolts as shown in detail in FIG. 3.

상기와 같이 케이스의 저면 전체가 리어 플로워 패널에 안착되어 지지됨에 따라 케이스 전체의 하중을 리어 플로워 패널에 부분적으로 집중시키지 않고 분산시키는 효과가 있게 된다.As described above, the entire bottom surface of the case is seated on and supported by the rear floor panel, thereby distributing the load of the entire case without partially concentrating the rear floor panel.

또한 상기 케이스(12)의 상부 후면은 차폭 방향으로 연장되게 형성된 리어 파 셀(14)에 고정되어 케이스(12)의 지지력이 향상됨과 더불어 차체의 강성도 향상되게 된다. 상기 케이스의 전면은 리어 시트와 평행하도록 경사지게 형성하여 장착하는 것이 바람직하다.In addition, the upper rear surface of the case 12 is fixed to the rear wave cell 14 formed to extend in the vehicle width direction, thereby improving the support force of the case 12 and also improving the rigidity of the vehicle body. The front surface of the case is preferably formed to be inclined so as to be parallel to the rear seat.

도 3에는 고압전장부품 케이스(12)가 차체에 장착된 상태의 사시도가 도시되어 있는 바, 상기 케이스(12)는 직방체 형상을 하고서 그 후면 상단이 리어 파 셀(14)에 3군데에서 볼트를 매개로 체결됨과 더불어 그 저면이 6군데에서 리어 플로워 패널 볼트를 매개로 체결되어 있다.3 is a perspective view of a state in which the high-voltage electric component case 12 is mounted on the vehicle body, and the case 12 has a rectangular parallelepiped shape, and the upper end of the case 12 is bolted to the rear parcel 14 at three places. In addition to being fastened by means of media, the bottom is connected to the rear floor panel bolts in 6 places.

한편, 도 4에는 본 발명의 다른 실시예에 따라 케이스가 차체에 장착된 상태의 단면에 도시되어 있는 바, 즉 상기 리어 플로워 패널(13)에 경사면을 형성하고, 직방체의 케이스 저면을 상기 경사면에 안착시켜 비스듬히 조립하는 구조를 도시하고 있다.On the other hand, Figure 4 is shown in the cross section of the case is mounted on the vehicle body according to another embodiment of the present invention, that is, the inclined surface is formed on the rear floor panel 13, the case bottom of the rectangular parallelepiped to the inclined surface The structure which mounts at an angle by mounting is shown.

또한 도 5에 도시한 바와 같이 케이스 자체의 강성을 증대시키기 위해 케이스(12)를 2개로 분할해서 1장의 플레이트(15)를 매개로 서로 연결시킨 구조가 도시 되어 있다.In addition, as shown in FIG. 5, in order to increase the rigidity of the case itself, the structure in which the case 12 is divided into two and connected to each other via one plate 15 is illustrated.

그리고 본 발명에서는 케이스와 리어 플로워 패널사이의 접지 면적이 크기 때문에 후방 충돌사고 발생시에 그 충격이 리어 플로워 패널로부터 케이스에 전달되기 쉬운데, 이 문제를 해결하기 위해 플로워 및 트렁크 주변의 강성을 저감하거나 플로워에 충격 흡수부를 마련하는 등의 일반적인 방법에 부가하여 케이스의 장착 볼트의 강성을 저하시켜 소정 이상의 충격이 가해지면 파단되도록 해서 케이스에 가해지는 충격을 저감시킬 수 있다.In addition, in the present invention, since the ground area between the case and the rear floor panel is large, the impact is easily transmitted from the rear floor panel to the case in the event of a rear collision, and in order to solve this problem, the rigidity around the floor and the trunk is reduced or the floor is solved. In addition to a general method such as providing a shock absorbing portion, the rigidity of the mounting bolts of the case can be lowered, and the impact applied to the case can be reduced by breaking when a predetermined or more impact is applied.

이상 설명한 바와 같이 본 발명에 따른 고압전장부품케이스의 차체장착구조에 의하면, 시트의 후방에 중량 부품을 탑재할 때에 부품 수납 케이스의 기능 외에도 케이스 자체가 차체의 강성을 향상시키고, 탑승자와 고압전장부품들이 서로 격리될 뿐만 아니라 차체의 강성이 높은 부위에 고압전장부품을 탑재함에 따라 충돌사고 발생시에 부품들의 전기 안정성도 향상되게 되며, 리어 필러 크로스 멤버나 부수의 브래킷을 사용할 필요가 없으므로, 차량의 중량 저하와 원가의 절감을 도모할 수 있는 등의 효과가 있다.As described above, according to the vehicle body mounting structure of the high-voltage electronic component case according to the present invention, when mounting a heavy component in the rear of the seat, in addition to the function of the component storage case, the case itself improves the rigidity of the vehicle body, the occupant and the high-voltage electrical component Not only are they isolated from each other, but the high-voltage electronic parts are mounted on the high rigidity of the car body, which improves the electrical stability of the parts in the event of a crash. There are effects such as reduction and cost reduction.
