SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a vehicle tonneau cover device for covering an upper surface opening of a luggage room provided on a rear side of a rear seat, wherein the tonneau cover covers an upper surface opening of the luggage room. A main unit, a winder disposed in a luggage room and configured to take up two series of wires, and one wire connected to the back door and connected to the other wire, thereby interlocking with the back door. And a slider that slides in the luggage room along the front-rear direction. The slider locks the rear side edge of the tonneau cover body to link the opening and closing operation of the back door, so that the rear of the tonneau cover body The side edge moves in the front-rear direction, and opens and closes the upper opening of the luggage room.

Here, if the tonneau cover body has a dimension capable of covering the upper opening of the luggage room, the material thereof may be a flexible tonneau cover sheet such as a fabric sheet, a nonwoven fabric sheet, or a synthetic resin sheet. And
A rigid shutter plate, a foldable board plate, or the like can be used.

When a tonneau cover sheet such as a fabric sheet is used, for example, the front edge of the rectangular tonneau cover sheet is fixed to the back of the rear seat, and the rear edge of the tonneau cover sheet is placed in the luggage room. If the slider slides back and forth on both sides and slides in the front-rear direction, the slider retreats to cover the upper opening of the luggage room. It hangs down and is stored on the front side in the luggage room.

If the front edge of the tonneau cover sheet is set in a free state, and the tonneau cover is provided so as to sandwich the tonneau cover from above and below the cover along the width direction, the front edge side hangs downward. , Can be stored in the luggage room.

Furthermore, if a configuration is adopted in which the four sides of the tonneau cover sheet are supported by a two-fold type split frame, the split frame can be deformed into a flat shape or a two-fold shape according to the reciprocating operation of the slider in this case as well. Thereby, the upper opening of the luggage room can be opened and closed.

When a rigid shutter plate is used as the tonneau cover body, the rear edge is locked to the slider in the same manner as the tonneau cover sheet.
Unlike the tonneau cover sheet, when the shutter plate is stored, if the storage direction is corrected by a guide holder for guiding the shutter plate downward, the shutter plate can be stored in the front space in the luggage room.

Further, according to the present invention, the tonneau cover main body is formed of a rectangular and flexible tonneau cover sheet, the front edge of the tonneau cover sheet is fixed to the front side of the luggage room, and the rear of the tonneau cover sheet is provided. Since the side edge is engaged with the slider, the slider retreats in response to the closing operation of the back door, and covers the upper opening of the luggage room with the tonneau cover sheet,
The slider moves forward in response to the opening operation of the back door,
The tonneau cover sheet is suspended and stored in the luggage room, and the luggage room is opened.

Here, even in the configuration using a drive motor instead of the winder, the tonneau cover body is not limited to a flexible tonneau cover sheet such as a fabric sheet, a nonwoven fabric sheet, or a synthetic resin sheet. , A shutter plate or a bellows-like member can be used.

Then, the take-up shaft is rotated by the drive motor, and the tonneau cover sheet is taken up on the take-up shaft, and the take-up shaft is detachable from the drive motor and the drum. And maintenance becomes easy.

As a drive system of the slider, a drum may be connected to a drive motor, a wire may be circulated between the drum and the guide roller, and the slider may be fixed to the circulated wire. A drive gear may be fixed coaxially, a circulation belt may be wound between the drive gear and the driven gear so as to be circulated, and a slider may be fixed to the circulation belt.

Further, if the drive motor, the drum, the guide rail, and the like are integrated into a unit, assembly can be performed easily.

Therefore, according to the present invention, when the back door is opened, the winding portion of the winder is rotated by the wire connected to the back door, and is wound around the winding portion. The wire on the other side circulates between the guide rollers, thereby causing the slider to move forward.

Since the rear edge of the tonneau cover body is locked to the slider, the tonneau cover body moves toward the rear side or the front side, so that the upper surface of the luggage room can be automatically opened. .

On the other hand, when the back door is closed, the take-up portion of the take-up device rotates in the opposite direction, whereby the slider fixed to the circulating wire is retracted, and the rear edge of the tonneau cover main body is moved. Is pulled out in synchronization with the slider, whereby the upper surface opening of the luggage room can be covered. Therefore, the tonneau cover main body can be linked with the opening and closing operation of the back door.

As described above, according to the present invention, the tonneau cover body eliminates the take-up spring as in the prior art, so that the capacity of the take-up device is small regardless of the capacity of the tonneau cover-side take-up spring. Since the capacity of the tonneau cover can be used, the take-up spring on the side of the tonneau cover is eliminated, and the capacity of the winder is reduced, the tonneau cover device can be made compact, and the labor for opening and closing the back door can be reduced.

Further, according to another embodiment of the present invention, the drive motor is driven in conjunction with the opening / closing operation of the back door,
This drive motor rotates the take-up shaft and drives the drive system of the slider. In this embodiment, the tonneau cover side take-up spring, the back door interlocking take-up device, and the back door and take-up device No connecting wire is required, and the equipment can be made compact. In addition, since the back door does not require a winding load, the opening and closing operation of the back door can be performed with small labor.
