Description

[Detailed explanation of the invention] This invention is based on four
This invention relates to an automobile in which a spare tire and a fuel tank are arranged so that the height of the rear floor of a wheel-drive automobile can be set at the same low position as the height of the rear floor of a front-wheel-drive automobile.

In ordinary passenger cars, the rear seats are placed slightly in front of the rear wheels, but in 1-box cars,
Many van-type vehicles such as wagons have seats directly above the rear axle. Layout 1 near the rear wheels for van-type front-wheel drive vehicles (FF vehicles)
An example is shown in FIG. Since this FF vehicle does not have a differential gear box on the rear axle, the rear floor 1a can be set at a low position, and even if the fuel tank 2 and spare tire 4 are placed below the rear floor 1a, the height of the rear floor 1a will remain low. You can secure enough seating space without raising the seats. In the figure, 5 is a rear gate, 6 is a rear seat, 8 is a rear wheel, 9 is a roof, and 10 is a passenger.

Figure 2 shows an example of the layout when a four-wheel drive vehicle (4WD vehicle) is developed based on this FF vehicle. In this case, since the rear axle is equipped with the differential gear box 3, the position of the rear floor 1b,
In other words, the height H of the rear wheel 8 from the axis is made higher than the height H from the axis of the rear wheel 8 of an FF vehicle (see Figure 1), and the rear floor 1b is raised by the increased height to secure space for the fuel tank 2. I will do it. Therefore, by raising the rear floor 1b, the space for the seat is narrowed, and either it is used as a child's seat or a space for luggage, or the roof 9 is raised to secure space for the seat, which greatly improves the product quality. spoil. For this reason, if the height of the rear floor of a 4WD vehicle could be set as low as that of a FF vehicle, the body structures of 4WD and FF vehicles could be unified, productivity would be improved, and it would be advantageous in terms of manufacturing and cost. Note that 4 in the figure
indicates the spare tire, and 5 indicates the rear gate.

The present invention has been developed in view of the above, and is applicable to automobiles in which the rear seat is located directly above the rear axle, the rear seat is installed on the rear floor, and a space is formed between the rear seat and the rear gate. A fuel tank is located at the rear, and a spare tire is stored in an upright position on the rear floor of the space, so that the upper part of the spare tire connects the upper edge of the seat back of the rear seat and the lower edge of the rear window. To provide an automobile characterized in that the distance between the floor surface of the spare tire storage part of the rear floor and the above line A-A is set to a size that allows the spare tire to be placed vertically so as to be located below the line A-A. .

Embodiments of the present invention will be described below with reference to FIGS. 3 to 5.

FIG. 3 shows the basic model (first embodiment) of the present invention, in which a fuel tank 2 disposed at the bottom of the rear floor 1 is located behind a differential gear box 3 disposed on the rear wheel axle, and the height of the rear floor 1 is H. is set to the same H dimension as the front wheel drive vehicle (FF vehicle) shown in FIG. The spare tire 4 is attached to the back surface of the seat bag 6' with a clamp 7 and placed on the rear floor 1 by utilizing the space between the seat bag 6' of the rear seat 6 and the rear gate 5. At this time, the spare tire 4 is housed below the line A--A connecting the lower edge of the rear window 11 provided on the seat back 6' and the rear gate 5 so as not to obstruct the rear view. In the figure, 8 indicates a rear wheel, and 9 indicates a roof. Further, 10 indicates a crew member.

FIG. 4 shows a second embodiment, which is basically the same as the first embodiment, but the difference is that in order to widen the rear visibility, the seat back 6' and the rear window 11 are
Since the A-A line connecting the lower edge of the rear floor 1 is lower than in the first embodiment, and the spare tire 4 must be lowered accordingly, a recess into which a part of the spare tire 4 fits is created in the rear floor 1. 1' to house the spare tire 4. The fuel tank 2 disposed behind the differential gear box 3 is formed by providing a recess 2' matching the shape of the rear floor recess 1'.

In the third embodiment shown in FIG. 5, a fuel tank 2 is housed between a recess 1'' formed in a rear floor 1 into which a spare tire is fitted and a differential gear box 3. Therefore, the spare tire 4 is placed in a seat back 6'. The recess 1'' of the rear floor is shaped to match this. A fuel tank 2 is placed in the space between this recess 1'' and the differential gear box 3.
to be placed. In this case, the spare tire is fastened and fixed to the rear floor 1 with a clamp 7. In addition, in FIGS. 4 and 5, the same reference numerals as in FIG. 3 indicate the same parts.

As mentioned above, this invention makes full use of the space between the seat back of the rear seat and the rear gate, and by placing a spare tire in this space, there is enough room under the rear floor to install a differential gear box. , body for 4 wheel drive vehicle and
When reusing it in a FF vehicle, it can be shared without changing the basic body structure (rear floor height, seat position).
Therefore, the effect is that productivity can be increased.

Furthermore, since the spare tire is disposed below the line A-A, there is an effect that the rear visibility is not obstructed.
