Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle body structure for a small vehicle, and is intended to enable a highly rigid vehicle body to be manufactured easily and at low cost.

There are various types of small vehicles, but for example, in a vehicle with a single occupant and intended for driving mainly in urban areas, it is important to reduce the vehicle weight as much as possible in terms of handling and fuel efficiency. Needless to say, this is desirable.

However, if the rigidity becomes low because of this, it is not desirable for safety. Furthermore, from the viewpoint of the manufacturer or the seller, it is desired that the product be easy to manufacture, have a wide range of variations by replacing some parts, and be convenient for transportation. This invention was made to satisfy these demands, and
To explain one embodiment with reference to the drawings, FIG. 1 shows a completed state of a Type 4 vehicle according to the present invention, where 1 is a body main body that is the lower half of the vehicle, and 2 is a body main body 1. 3 is a roof panel whose front edge is joined to the front panel 2, and 4 is a panel whose front edge is joined to the roof panel 3. The lower edge of this rear panel 4 is fixed to the rear of the main body 1. Reference numeral 5 designates a door panel, which is hinged to the main body 1, and reference numeral 6 represents a seat portion. FIG. 2 shows an exploded state of each of these parts.

The main body 1 is integrally formed of synthetic resin and includes the following parts.

As shown in FIG. 3, the body main body 1 has a floor section la on which a passenger rides, and from the front and rear of this floor section la, the right side, and the left side excluding the door panel 5 (see FIGS. 1 and 2). In this case, an interior wall lb stands upwardly, and a vehicle interior space lc is formed by the floor portion la and the interior wall lb.

A flat part ld facing outward is formed at the upper end of the indoor wall lb, and an outdoor wall le extends downward from the outer end of the flat part ld. , plane part ld,
A buffer space lf is formed surrounded by the outdoor wall le.

This buffer space lf is also formed on the right side of the body main body 1 and on the left side excluding the door panel 5 portion. The exterior wall le forms the outer shell of the lower half of the vehicle. As shown in FIG. 3, the front panel 2 is mounted on the flat part ld at the front of the main body 1, and the rear panel 4 is
As shown in Fig. 4, the flat parts ld on both rear sides of the body 1
The body main body 1, front panel 2, and rear panel 3 are fixed together using rivets, tapping screws, bolts, adhesives, or the like.

What is shown in FIG. 5 is a chassis frame, and this chassis frame 7 consists of two pipes 8, 9 bent in a concave shape, and four pipes 10, 11, 12, 13.
It is formed by crossing the bridge.

And screw holes 14 are provided in these pipe materials 8 to 13, respectively.
A cut bracket 16 is attached by welding. These brackets 15 connect the body body 1 and the chassis frame 7 by receiving bolts (not shown) inserted through bolt insertion holes (not shown) drilled in the body body 1 side. (See Figure 6). Since this invention is configured as described above, it has the following effects.

'11 The body is integrally formed from synthetic resin, making it easy to manufacture.Moreover, buffer spaces are formed on the front, rear, left and right sides surrounded by the interior wall, the following flat section, and the exterior wall, resulting in increased rigidity. A fully secured vehicle body can be obtained.

■ Parts other than the main body can be made of resin or thin steel plates, which is advantageous in terms of overall cost.

[3' It is advantageous in terms of manufacturing because the number of parts is small.

■ The shape of parts other than the main body can be easily changed, resulting in a wide range of variations. {51 Since the entire body can be easily assembled, the main body and other parts can be transported separately, which is extremely advantageous in terms of transportation.
