Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure of an automobile, and more particularly to a vehicle body structure in which the rear half of the roof can be opened and closed to form a so-called open car.

2. Description of the Related Art In an automobile, an opening is formed in a vehicle body roof as shown in, for example, Japanese Patent Laid-Open No. 59-6126, and a lid is attached to the roof opening so as to be openable and closable. With a so-called sunroof that can open the roof opening by using
There are things that were made to be convertible cars.

Problems to be Solved by the Invention However, in the above-mentioned sunroof, even when the roof opening is opened, the area around the roof opening of the vehicle body remains,
There is a lack of openness. Further, in the above-described open car structure, it is troublesome to attach and detach the vehicle body roof and to store and arrange the removed vehicle body roof.

Therefore, it is conceivable to configure the vehicle body roof to be openable and closable, but even if the vehicle body roof is simply opened and closed, if the opening and closing is done manually, the opening and closing operation is troublesome, so it is difficult to suddenly adopt it. It is a thing.

Accordingly, the present invention provides a vehicle body structure for an automobile, in which the vehicle body roof can be easily opened and closed to form an open car.

Means for Solving the Problems In the present invention, a vehicle body opening including a trunk room opening and a roof opening formed from the trunk room opening to an intermediate portion in the front-rear direction of the vehicle body roof is formed in a vehicle body. On the other hand, a rear deck is attached to the front half of the trunk room opening of the vehicle body opening so as to be openable and closable through a tilting / sliding device, and the roof opening of the vehicle body opening extends from the roof opening to the front half of the trunk room opening. The opening and closing roof that can be stored in the front part of the luggage compartment via the
Further, the rear switch is opened by turning the operation switch on to the roof open side or on the roof close side, and it is detected whether the rear switch is fully opened or stopped, and the open / close roof is opened or closed by the operation switch. Corresponding to one of the ON operations, it opens from the fully closed position to the fully open position or closes from the fully open position to the fully closed position, and the open / closed stop or the closed stop of the roof is detected to detect the rear deck in the fully open state. A control means for closing is attached.

When the operation switch is turned on to the roof open side or turned on to the roof close side, the rear deck first opens and stops at its fully open position, and then the open / close roof turns on either the roof open or roof close of the operation switch. Along with the operation, it is moved from the fully open position to the fully closed position or from the fully open position to the fully closed position, and then the rear deck is closed to complete a series of operations.

When the opening / closing of the rear deck F and the opening / closing roof J according to the above-described embodiment structure is performed according to the flow chart shown in FIG. 7, when the operation switch Y arranged around the driver's seat is turned on, the tilt / slide device is operated by the section. By driving G, the rear deck F is opened from the fully closed position of the solid line shown in FIG. 2 to the fully open position of the phantom line, and it is judged by the section whether the first sensor U is on or off. In that case, the processing of the section is continued, and when the first sensor U is turned on, the driving of the tilt / slide device G is stopped by the detection signal of the first sensor U, and at the same time, the operation switch Y is turned on. It is determined whether the operation is roof opening or roof closing. In the case of roof opening, the rotating device T is driven by the section to open / close the roof J by the solid line shown in FIG. When the third sensor W is turned off, the processing of the third sensor W is continued, and when the third sensor W is turned on, the third sensor W is turned on and off. In response to the detection signal of the third sensor W, the driving of the rotating device T is stopped, and the tilt / slide device G is driven in the opposite direction by the section to close the rear deck F from the fully open position to the fully closed position. The second sensor V is turned on / off by the section, and if the second sensor V is off, the section processing is continued, and if the second sensor V is on, the detection signal of the second sensor V is detected. Thus, the reverse drive of the tilt / slide device G is stopped, the series of operations by the roof opening operation of the operation switch Y is completed, and the opening / closing roof J is smoothly connected to the front of the trunk lid H by the rear deck F. Cover It is stored in the front part of the luggage compartment in the opened state, and the roof opening D is opened. On the other hand, when the judgment in the section is roof closing, the turning device T is driven in the opposite direction by the section to open and close the roof. When J is closed from the fully open position, the section determines whether the fourth sensor X is on or off. When the fourth sensor X is off, the section processing is continued, and when the fourth sensor X is on, the fourth sensor X is turned on. The reverse drive of the rotating device T is stopped by the detection signal of the sensor X, the processing of the section and the judgment of the section are continued, the rear deck F is closed to complete a series of operations, and the opening / closing roof J is closed. Is smoothly connected to the rear of the vehicle body roof front half I to close the roof opening D, and the rear deck F
Connects smoothly to the rear of the opened and closed roof J and the front of the trunk lid H to close the front half of the trunk room opening B.

As described above, according to the present invention, by turning on the operation switch, the rear deck can be opened first, and then the open / close roof can be opened or closed, and then the opened rear deck can be closed. The open / close roof can be easily opened / closed with the operation switch's one-touch to make it into an open car or a vehicle body with a roof, and when it is an open car, the open / close roof is stored with the rear deck covering the front of the trunk room. While the appearance can be ensured because it is possible, when the vehicle with roof is used, the front part of the trunk room can be effectively utilized as a luggage room, which is a great practical effect.
