Description

  The present invention relates to an apparatus for a vehicle body comprising: an electric device including at least one of a vehicle driving capacitor and a high-voltage electrical component for driving the capacitor; and a vehicle body having a mounting space for mounting the electric device. More particularly, the present invention relates to a vehicle body device mounting structure that can be shared by a vehicle body for a front-wheel drive vehicle using only front wheels as drive wheels and a vehicle body for a two-wheel drive vehicle using front wheels and rear wheels as drive wheels.

  There is a vehicle (hybrid vehicle) including an internal combustion engine and an electric motor (motor) as a drive source. In such a hybrid vehicle, for example, as shown in Patent Document 1, an engine and an electric motor, which are driving sources, are mounted in an engine room on the front side of the vehicle, and a fuel tank that supplies fuel to the engine is provided below the front seat. And an electric device incorporating a high-voltage electrical component including a battery (capacitor), which is an energy source of the motor, and an inverter for the battery, is mounted in the under floor space of the luggage compartment (luggage space) behind the vehicle.

  Further, there are two types of vehicle driving modes: a front-wheel drive vehicle in which only the front wheels of the front and rear wheels are drive wheels, and a four-wheel drive vehicle in which both front wheels and rear wheels are driven. The hybrid vehicle as described above is applied not only to a front wheel drive vehicle but also to a four wheel drive vehicle. However, a four-wheel drive vehicle is provided with a differential device for distributing and transmitting driving force between the left and right rear wheels. For this reason, if the electric device incorporating the battery and the high-voltage component is mounted in the underfloor space of the cargo compartment, the mounting position of the differential device and the mounting position of the differential device overlap, so the mounting position of the electric device must be changed. Don't be. Therefore, even in the same vehicle type, it is necessary to make the mounting position of the electric device different between the vehicle body for a four-wheel drive vehicle and the vehicle body for a front wheel drive vehicle.

  In this case, if the vehicle skeletons (frames) with different configurations are used for the front-wheel drive vehicle and the four-wheel drive vehicle due to the different mounting positions of the electric devices, the number of depreciated frames will be reduced and the vehicle manufacturing cost will be reduced. There is a problem of hindering. Furthermore, if the vehicle skeleton and the vehicle body structure are different between the front-wheel drive vehicle and the four-wheel drive vehicle, there is a problem that the development man-hour of the vehicle increases accordingly.

  The present invention has been made in view of the above-described points, and an object of the present invention is to mount an electric device incorporating a battery and a high-voltage electrical component at different positions between a front-wheel drive vehicle and a four-wheel drive vehicle. It is an object of the present invention to provide a device mounting structure for a vehicle body that can share a structure and can reduce the manufacturing cost of a vehicle and simplify the manufacturing process.

  In order to solve the above problems, an apparatus mounting structure for a vehicle body according to the present invention includes an electric device (10) including at least one of a vehicle driving capacitor and a high-voltage electrical component for driving the capacitor, and an electric device. A vehicle body device mounting structure including a vehicle body (1) having a mounting space (30) for mounting (10), wherein the mounting space (30) is a luggage compartment provided at a rear portion of the vehicle body (1). (2) A support member (15) that is disposed in a space including the space between the left and right rear wheels (WR) on the lower side and extends in the width direction of the vehicle body (1) to support the electric device (10). And a skeleton member (5) provided on the vehicle body (1) side to which the support member (15) is fixed, and by directly attaching the support member (15) to the skeleton member (5), an electric device ( 10) is the first mounting position (30-1) in the mounting space (30). On the other hand, the electrical device (10) is mounted in the first space in the mounting space (30) by attaching the position adjusting component (20) between the support member (15) and the skeleton member (5). It is configured to be mounted at the second mounting position (30-2) which is higher than the mounting position (30-1).

  When the vehicle body (1) is used as a vehicle body for a front-wheel drive vehicle that uses only the front wheels as drive wheels, the electric device (10) is mounted at the first mounting position (30-1), and the vehicle body (1) is mounted on the front wheels.

Are connected obliquely. Thereby, it becomes possible to more firmly support the electric device with respect to the skeleton member.

  In the above-described vehicle body device mounting structure, the first fixing member (40-1) for fixing the first fixing portion (21, 22) of the position adjusting component (20) to the support member (15), and the second A second fixing tool (40-2) for fixing the fixing portions (23, 24) to the skeleton member (5), and a first fixing for fixing the skeleton member (5) to the support member (15). A hole (16) and a second fixing hole (17) for fixing the position adjusting component (20) are provided, and the first fixing portion (21, 22) of the position adjusting component (20) is provided. It is good to comprise so that a 2nd fixing tool (40-2) may be arrange | positioned in the position which opposes a 1st fixing hole (16) in the state fixed to the 2nd fixing hole (17) of the support member (15). .

  According to this configuration, the second fixture is positioned below the second fixing hole in a state where the first fixing portion of the position adjusting component is fixed to the first fixing hole of the support member. Thus, the second fixing tool arranged on the lower side of the support member through the second fixing hole can be visually observed. Therefore, it can be confirmed that the position adjusting component and the skeleton member are securely fixed by the second fixing tool.

  In the above-mentioned vehicle body mounting structure, the second fixture (40-2) is a fixing bolt and is a tool inserted into the first fixing hole (16) of the support member (15). You may comprise so that (40-2) may be fastened.
