Description

[Detailed Description of the Invention] The present invention relates to a vehicle body structure of a pick-up type truck that shares the front part of the vehicle body with a sedan type vehicle.

Conventionally, the vehicle body of a pick-up type truck has generally had a cabin section and a loading platform section behind it integrated into a monocoque structure.

The present invention divides the vehicle body structure of a pick-up truck into a cabin section and a loading platform section, the cabin section has a monocot structure, and the loading platform section is configured as a frame type in which the loading platform is supported on a frame, and the front end of the frame is By having a structure in which the cabin is connected to the rear part of the pickup truck, the cabin part of the pickup type truck can be used in common with a sedan type general passenger car, thereby reducing production costs.

The present invention will be explained below with reference to the accompanying drawings.
2 indicates a front floor, and 2 indicates a frame. The front body portion, that is, the cabin portion a, including the front floor 1 and frame 2, is a part shared with a sedan type automobile and has a monocot structure.

The loading platform part b is constructed in a frame type.
That is, the front end of the frame 4 that supports the loading platform is
It is fastened and fixed by bolts 9 and nuts 10 to a frame 7 (both ends of which are connected to a center pillar (not shown)) provided at the lower part of a back panel 3 that partitions the cabin part a and the loading platform part b.

A cross member 6 is fixed to the frame 4 near the joint with the cabin part a, and a reinforcement member whose front end is formed at the rear end of the front floor 1 below the frame 7 is attached to the lower part of the cross member 6. The rear end of the frame 5 is fixed by welding or the like, and the rear end of the frame 5 is tightened and fixed to the frame 8 with a bolt 9 and a nut 10.
By connecting it to the cross member 6, the load applied to the joint part is dispersed into compressive and tensile loads, thereby preventing the load from being concentrated on one part.

The rear surfaces on both sides of the cross member 6 are mounting surfaces 6 for suspension devices such as trailing arms 11 for supporting the rear wheels.
It is configured in a.

As mentioned above, according to the present invention, by making the cabin part a monocot structure, it can be used in common with a sedan-type car body, which can significantly reduce production costs, and by making the rear cargo area a frame type. It is extremely advantageous in practical terms because it can be mounted on a variety of loading platforms and can be used for multiple purposes.

In addition, the connecting part between the monocot structure cabin part and the frame-type loading platform is constructed by providing two frames 5 at the bottom of the frame 4 supporting the loading platform and connecting them to the cross member 6. Therefore, a compressive load mainly acts on the frame 4, which is received by the frame 7 and distributed to the center pillar, side sills, etc., and a tensile load mainly acts on the frame 5, which is received by the front floor 1 and It is possible to prevent a load from being concentrated on one part, such as being distributed to the cross member 6. Furthermore, with a simple structure, such as using the rear surface of the cross member 6 as a mounting surface for the rear wheel suspension, it is possible to exhibit extremely rational and effective functions.

If necessary, a reinforcing member may be inserted into the frame 7, which is the mounting portion of the frame 4, to improve the strength.
