BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle roof opening / closing mechanism for opening and closing a lid to store a roof in a storage portion.
In particular, the present invention relates to an automobile roof opening / closing mechanism having a simplified structure.

[0002]

2. Description of the Related Art Conventionally, a roof opening / closing mechanism has been adopted for an automobile having an openable / closable roof. Although various types of roof opening / closing mechanisms have been proposed, for example, there is one in which an opened roof is stored in a storage portion formed in the rear portion of the vehicle compartment. This type of roof opening / closing mechanism is generally provided with a lid for opening / closing the storage section. As a conventional example of such a roof opening / closing mechanism, Japanese Patent Application Laid-Open No. 3-167 is known.
There is one described in No. 030.

Now, a conventional example of the roof opening / closing mechanism for an automobile as described above will be described in detail with reference to FIG.
As shown in the figure, the roof 2 is provided so as to be openable and closable with respect to the vehicle body 1. A hydraulic cylinder 4 is attached to the roof 2 via a roof link 7. Further, the storage portion 1a is provided with a plate-shaped lid 3 that opens and closes the storage portion 1a. A hydraulic cylinder 5 is attached to the lid 3 via a lid link 8.

In the vehicle roof opening / closing mechanism having such a structure, when the roof 2 is opened, the hydraulic cylinder 5 first extends to rotate the lid link 8 in the clockwise direction to open the lid 3. Subsequently, the hydraulic cylinder 4 contracts, the roof link 7 rotates clockwise, and the roof 2
Collapses to the side of the storage unit 1a and is stored in the storage unit 1a. Finally, the hydraulic cylinder 5 contracts, the lid link 8 rotates counterclockwise, and the lid 3 closes.

On the other hand, when closing the roof 2, the hydraulic cylinder 5 extends and the lid link 8 rotates clockwise to open the lid 3, and then the hydraulic cylinder 4 extends and the roof link 7 rotates counterclockwise. When the roof 2 rotates in the rotation direction, the roof 2 comes out of the storage portion 1a and covers the vehicle compartment. Finally, the hydraulic cylinder 5 contracts, the lid link 8 rotates counterclockwise, and the lid 3 closes.

[0006]

In the conventional roof opening / closing mechanism for an automobile as described above, a cylinder for opening / closing the roof and a hydraulic cylinder for opening / closing the lid are separately provided. Usually, separate roof opening / closing mechanisms are provided on both the left and right sides of the vehicle body so that the roof and the lid can be stably opened and closed. Therefore, the total number of hydraulic cylinders installed is two, two on each side. Although not shown, another hydraulic cylinder may be used to push the closed roof 2 toward the vehicle body.

As described above, in the prior art, the number of hydraulic cylinders installed is large, and the piping for supplying and discharging fluid to the hydraulic cylinders is complicated. Therefore, there is a problem that it is difficult to lay out the constituent members and the weight is heavy, and moreover, the production cost is increased.

The present invention has been proposed to solve the above problems, and its purpose is to reduce the number of cylinders installed, simplify piping, and increase the degree of freedom in the layout of the constituent members. It is an object of the present invention to provide a roof opening / closing mechanism for an automobile, which achieves weight reduction and production cost reduction.

[0009]

To achieve the above object, a roof opening / closing mechanism for an automobile according to the present invention includes a roof provided on a vehicle body so that the roof can be opened and closed, and a roof link rotatably attached to the roof. A roof housing portion provided on the vehicle body, a lid for opening and closing the housing portion, a lid link rotatably attached to the lid, a cylinder body, and a cylinder rod slidable on the cylinder body. A retractable cylinder, one of which is connected to the roof link and the other of which is connected to the lid link, first locking means for locking the roof or the roof link at a position where the roof is closed, and the lid for storing part. Second locking means for locking the lid or the lid link at the closed position, and the lid or the lid link at the position where the lid opens the storage section Third locking means that, characterized in that it comprises a fourth locking means for locking the roof or link roof at the position where the roof is accommodated in the storage unit.

[0010]

The operation of the vehicle roof opening / closing mechanism of the present invention having the above-described structure is as follows. That is, when the roof is opened and stored in the storage portion on the vehicle body side, the opening operation of the lid is first performed. The first locking means locks the roof or the roof link when the roof is in the closed position.

When the cylinder extends in this state, since the first locking means locks the roof or the roof link, the members of the cylinder body and the cylinder rod connected to the roof link side do not move, and the members for the lid are not moved. Only the members connected to the link side move. Therefore, the extending force of this member rotates the lid link to open the lid. Then, when the lid is opened, the third locking means locks the lid or the lid link.

Subsequently, the opening operation of the roof is performed. That is, if the cylinder extends further with the lid open,
Since the third locking means locks the lid or the lid link, the member connected to the lid link side of the cylinder body and the cylinder rod does not move, and only the member connected to the roof link side moves. The force of extension of this member causes the roof link to rotate and open the roof.
The fourth locking means locks the roof and the roof link when the opened roof is stored in the storage part.

Finally, the lid closing operation is performed. That is, when the cylinder contracts when the roof is open, the fourth locking means locks the roof and the roof link, so that the members of the cylinder body and the cylinder rod connected to the roof link side do not move and the lid does not move. Only the members connected to the work link side move. Therefore, the contracting force of this member causes the lid link to rotate and close the lid. When the lid is finally closed, the second locking means locks the lid or the lid link.

On the other hand, when the roof is closed to cover the vehicle body side,
The lid opening operation, the roof closing operation, and the lid closing operation are performed in this order. Among these operations, the opening operation of the lid is basically the same as the above-described opening operation of the lid, except that the means for locking the roof or the roof link is not the first locking means but the fourth locking means. The closing operation of the lid is basically the same as the closing operation of the lid described above, except that the means for locking the roof or the roof link is the first locking means instead of the fourth locking means. .

Further, when the roof is closed, when the cylinder contracts with the lid open, the third locking means locks the lid or the link for the lid. The members connected to the link side do not move, and only the members connected to the roof link side move. The contracting force of this member causes the roof link to rotate and close the roof. When the closing roof covers the vehicle body, the roof is in the closed position, and the first locking means locks the roof and the roof link.

As described above, in the vehicle roof opening / closing mechanism of the present invention, it is possible to open / close the roof and the lid with a single cylinder. Therefore, the piping for supplying / discharging the fluid to / from the cylinder can be simplified,
The configuration can be simplified.
