Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automobile body structure, and more particularly to a vehicle body structure that can be turned into a so-called open car by opening and closing the rear half of the roof.

Conventional technology In some automobiles, an opening is formed in the roof of the vehicle body, and a lid is attached to the roof opening so that the lid can be opened and closed, as shown in Japanese Patent Laid-Open No. 59-6126, for example. The vehicle is equipped with a so-called sunroof that allows the roof opening to be opened, or the roof of the vehicle is removable.
There is one that can be turned into an open car.

Problems to be Solved by the Invention However, in the above-mentioned sunroof, even if the roof opening is opened, the area around the roof opening of the vehicle roof remains.
I tend to lack that sense of openness.

Furthermore, in the above-mentioned open car structure, it is troublesome to attach and detach the vehicle roof, and to store and arrange the removed vehicle roof.

Therefore, it is conceivable to construct the car body roof in an opening/closing type, but even if the car body roof is simply made in an opening/closing type, if the opening/closing operation is made manual, it is difficult to suddenly adopt it because the opening/closing operation is troublesome. It is something.

Therefore, the present invention provides a car body structure that allows the car body roof to be easily opened and closed to convert the car into an open car.

Means for Solving the Problems In the present invention, a vehicle body opening is formed in the vehicle body, and includes a trunk opening and a roof opening extending from the trunk opening to an intermediate portion of the vehicle roof in the longitudinal direction. On the other hand, a rear deck is attached to the front half of the trunk opening of the vehicle body opening via a tilt/slide device so as to be freely openable and closable, and the rear deck is attached to the roof opening of the vehicle body opening via the front half of the trunk opening. The opening/closing roof, which can be stored in the front part of the luggage compartment, is assembled so that it can be opened and closed via a hinge and a rotating device.
Further, by turning on the operation switch to the roof oven side or turning the operation switch to the roof close side, the rear deck is opened, and by detecting that the rear deck has stopped fully opening, the roof can be opened or closed to either the roof oven or roof close position of the operation switch. In response to the ON operation of the roof, the roof moves from the fully closed position to the fully open position, or from the fully open position to the fully closed position, and upon detecting the stoppage of opening or closing of the opening/closing roof, closes the deck in the fully open state. It is equipped with control means.

When the operating switch is turned on to the roof open side or the roof closed side, the rear deck first opens and stops at the fully open position, and then the opening/closing roof is turned on when either the roof open or roof closed position of the operation switch is turned on. In accordance with the operation, the rear deck opens from the fully open position to the fully closed position or closes from the fully open position to the fully open position, and then the rear deck moves to close, completing a series of operations.
