Abstract

PURPOSE:To lift a roof at the time of opening a lid for enabling the whole of the lid to retreat slidably to the rear part of the roof, and enlarge or otherwise a roof opening area by so positioning the roof at the rear side of the roof opening as to be freely liftable. CONSTITUTION:In opening a sun roof lid 4, a rear roof 2 is preliminarily raised with a lift mechanism 7, and a gap S for allowing the passage of the sun roof lid 4 is formed between the rear roof 2 and a frame rear part 5A. Thereafter, the sun roof lid 4 is slided aft via the aforesaid gap S and a roof opening part 3 is thereby made wide open. On the other hand, when the sun roof lid 4 is tilted up, a roof 3 is also lifted and the cabin air (a) is exhausted outside through the aforesaid gap S. Also, only the rear roof 2 is lifted with the sun roof lid 4 closed. and the air (b) flowing along the roof 2 is so deflected as to move along the surface of a back door 9 via the gap S, thereby preventing the deposit of dusts on the aforesaid door surface 9.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a sliding sunroof structure for an automobile.

BACKGROUND OF THE INVENTION Some conventional automobiles are known in which a sunroof lid is slid from a roof opening toward the rear outside the vehicle, as disclosed in, for example, Japanese Patent Application Laid-Open No. 62-253521. Specifically, a guide rail is provided on both sides of the front part of the sunroof lid that engages with guide rails laid on both side edges of the roof opening. After lifting it higher up, you can slide it onto the rear part of the roof.

Problems to be Solved by the Invention As mentioned above, in the so-called outer slide sunroof structure in which the sunroof lid slides toward the rear outside the vehicle,
The slide stroke of the sunroof lid is restricted by the rear edge of the roof opening and becomes shorter, and the front part of the sunroof lid with the guide roller remains inside the roof opening, resulting in a narrowing of the actual opening area. . SUMMARY OF THE INVENTION Therefore, the present invention provides a sliding sunroof structure for an automobile, in which the entire sunroof lid can be slid toward the rear of the roof, thereby increasing the roof opening area.

Means for Solving the Problem In a structure in which the sunroof lid slides from the roof opening toward the outside of the vehicle, the roof can be raised and lowered to a height that allows the sunroof lid to pass through using a lifting mechanism behind the roof opening. It is located in.

Operation When the lid is opened, the roof is raised on the rear side of the roof opening by the operation of the lifting mechanism to form a gap through which the sunroof lid can pass. The sunroof lid slides rearward through this gap and retreats to a position out of the plane of the roof opening.

Example Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 3, ■ indicates the vehicle body, and the roof 2 has a roof opening 3 in which a sunroof lid 4 is arranged.
It is formed. The peripheral edge of the roof opening 3 is reinforced with a sunroof frame 5.

This sunroof frame 5 has its both sides joined to roof site rails (not shown), which are roof frame members, and
The rear side of the sunroof frame 5 extends to the rear roof rail 6 of the frame member and is joined to the rear roof rail 6. Frame rear part 5A on the rear side of the roof opening 3
A rear roof 2A that covers the sunroof lid 4 is formed separately and can be raised and lowered to a height that allows the sunroof lid 4 to pass through, by means of a lifting mechanism 7 such as a hydraulic actuator provided on both sides of the rear frame 5A. Also, this sunroof free
The RAD 4 is moved from both sides of the roof opening 3 to the rear part 5A of the frame.
Guide rails laid across the area and sunroof lid 4
The entire lid can be slid back onto the rear part 5A of the frame while being guided by guide rollers provided in the lid (both guide rails and guide rollers are not shown). The operation of the elevating mechanism 7 is independently controlled, and the operation is also controlled in conjunction with the sliding and tilting operations of the sunroof lid 4. When the sunroof lid 4 is operated backward, the elevating mechanism 7 operates upward, and the sunroof lid 4 moves forward.

When the lid is closed, the sunroof lid 4 is lowered.
It is designed to rise and fall in synchronization with the tilt up and tilt down of the camera. In the figure, 8 indicates a front window panel, 9 indicates a back door, and IO indicates a roof trim.

According to the above embodiment structure, when the lid is opened, the rear roof 2A is raised by the lifting mechanism 7 before the sunroof lid 4 slides backward, and there is a gap S between the rear roof 2A and the frame rear part 5A through which the sunroof lid 4 can pass. form. Following the rise of the rear roof 2A, the sunroof lid 4 slides rearward through this gap S, and the roof opening 3
The roof opening 3 is fully opened by retreating to a position above the rear frame 5A that is out of the plane of the frame.

When the sunroof lid 4 is tilted up, the rear roof 2A also rises as shown in FIG. 4, and the connected state between the rear edge of the sunroof lid 4 and the front edge of the rear roof 5A is maintained.
Air inside the vehicle is ventilated to the outside of the vehicle through a gap S as shown by arrow a in the figure.

Next, with the sunroof lid 4 closed, when the lifting mechanism 7 is activated to raise the rear roof 2A, a gap -5S is formed between the rear roof 2A and the rear frame 5A as described above. Therefore, the air flowing along the roof 2 is deflected through the gap S to flow along the surface of the back door 9, as shown by the arrow in the figure, and dust is not deposited on the surface of the back door window panel 9A. This allows the rear roof 2A to effectively function as a rear wind guide device.

FIG. 6 shows the present invention applied to a T-bar roof specification vehicle. The roof center 2B and the rear roof 2A are integrally molded into a T-shaped plane, and the front end of the roof center 2B is hinged to the front roof 2C so as to be freely rotatable in the vertical direction.

The sunroof frame 5 is formed to match the shape of the roof, and a lifting mechanism 7 is provided on both sides of the rear part 5A of the frame so that the rear roof 2A can be raised and lowered together with the roof center 2B around the hinge point. . Further, the sunroof lid 4 is an integral type spanning the left and right roof openings 3.3, and is provided at the frame center 5 of the roof frame 5.
It is possible to slide in the front-back direction along a guide rail (not shown) laid from B to the rear of the frame 15A. Of course, the sunroof lid 4 may be provided as separate left and right parts.

Therefore, even in the case of this embodiment, when the lid is opened, the rear roof 2A is moved to the roof center 2 by the lifting mechanism 7.
A gap S is formed between the sunroof frame 5 and the sunroof frame 5 through which the sunroof lid 4 can pass. 5
A can be moved upwardly and the roof opening 3 can be fully opened.

Effects of the Invention As described above, according to the present invention, the roof is disposed on the rear side of the roof opening so that it can be raised and lowered freely by the raising and lowering mechanism, so that when the lid is opened, the roof is raised and the entire sunroof lid is moved to the roof opening. This has a great practical effect in that it can be slid back to the rear part of the roof that is separated from the outer sliding sunroof structure, thereby eliminating the narrowing of the roof opening area, which can be said to be a weak point of the outer sliding sunroof structure.
