Description

[Detailed Description of the Invention] The present invention relates to an improvement in the body structure of a vehicle in which the space between the side rail and the roof panel is configured as an air passage for ventilation in the vehicle interior.

Generally speaking, in trucks and low-priced vehicles, the interior side of the roof side rails and the interior side of the pillars located above the vehicle body are finished with sheet metal painting only, and the ceiling lining is made of soundproofing and heat-insulating padding and skin. Many cars have a body structure in which a two to three-layer laminate is directly adhered to the side surface of the roof panel in the passenger compartment. If the edge is inserted to the inside of the roof side rail and bonded, there are advantages such as the ability to improve the aesthetic appearance without requiring finishing of the edge of the lining material.

However, in the above structure, as shown in FIG. 2, an air passage 3 for ventilation of the vehicle interior is formed between the roof panel 1 and the side rail 2, and When a gap 6 is provided between the roof panel 1 and the ceiling lining material 5 and the gap 6 is used as an air intake port from the indoor 7 side to the air passage 3, the ceiling lining material 5 is the second As shown by the chain line in the figure, it peels off from the roof panel 1 and closes the gap 6, resulting in a problem that the room 7 is not sufficiently ventilated.

In addition, the edge of the ceiling lining material 5 is difficult to adhere to with adhesive, and is difficult to attach since it is inserted into a narrow space, and is also a location where the above-mentioned peeling is likely to occur.

The present invention was proposed in view of the above, and includes an air passage for ventilation in the vehicle interior between the inner edge of the side rail whose outer edge is joined along the outer periphery of the roof panel and the interior surface of the roof panel. The outer peripheral edge of the ceiling lining material that is affixed to the inner surface of the roof panel faces into the air passage through a gap that exists between the inner edge and the inner surface of the roof panel. A notch is formed along the longitudinal direction of the inner edge of the side rail facing the ceiling lining material, and the air passage is configured to communicate with the vehicle interior through the notch. The main feature is the car body structure, and even if the edge of the ceiling lining material peels off as described above, the above-mentioned notch ensures communication between the passenger compartment and the air passage, allowing normal ventilation in the passenger compartment. It has the following effects:

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

Similarly to the conventional example shown in FIG. 2, 10 is a side rail disposed on the upper side of the vehicle body, and the outer peripheral edge of the roof panel 14 is welded to its outer edge, that is, its outer lower edge 12. An air passage 18 for ventilation inside the vehicle compartment 16 is formed between the side rail 10 and the side rail 10.

A certain ceiling lining material 20 is attached to the inner surface of the roof panel 14 on the passenger compartment 16 side, which is made of a laminated material in which a pad material for heat and sound insulation and a skin material are integrated.
The outer edge 22 extends into the air passage 18.

A notch 26 is provided along the longitudinal direction of the side rail 10 at the inner edge of the side rail 10, that is, the upper edge 24 inside the vehicle compartment 16.

Note that a gap 28 is formed between the ceiling lining material 20 and the upper edge 24 of the side rail 10.

According to the above configuration, when the ceiling lining material 20 is not peeled off, the air inside the vehicle compartment 16 flows into the air passage 18 through the gap 28 and the notch 26 to perform ventilation, and the ceiling lining material When 20 is peeled off as shown by the chain line in FIG. 2, ventilation is performed through the notch 26, so communication between the casing 16 and the air passage 18 is blocked, and the ventilation inside the casing 16 is hindered. This is prevented.

Further, a notch 26 is provided on the upper edge 24 of the side rail 10.
Since it is only necessary to provide the following, there are no problems such as increased cost.

In the above embodiment, a gap 28 was formed between the ceiling lining material 2o and the upper edge 24 of the side rail 10, but this gap 28 was eliminated from the beginning of assembly so that the upper edge 24 was connected to the ceiling lining material 2o. Needless to say, it may be configured so as to come into contact with the material 20.
