Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> This invention relates to a sunroof structure for an automobile.

<Prior Art> Conventional sunroof structures for automobiles include those shown in Figures 6 to 9, for example [Service Bulletin No. 588 (Nissan Motors, published in 1988), page D-37. reference〕.

Generally, a sunroof is provided with a rectangular roof opening 2 in a roof panel 1 as shown in FIG. 6, and this roof opening 2 is equipped with an opening/closing lid 3 and a sunshade 4 that can be slid back and forth.

By opening the opening/closing lid 3 and the sunshade 4, a sense of freedom is given to the occupants, and excellent ventilation can be achieved.

A welt 5 is attached to the opening/closing lid 3 over the entire circumference in order to improve the sealing of the passenger compartment when the roof is fully closed. Furthermore, right below the front end of the roof opening 2, there is a train part 6 on the front side of the roof opening 2 for receiving rainwater etc. that enters from between the opening/closing lid 3 and the roof panel l when the roof is fully closed. Rail body 8 fixed on frame 7
It is divided into sections. Further, a seal rubber 9 projecting upward is attached to the front end of the sunshade 4. This is because when driving with the opening/closing lid 3 and sunshade 4 stored between the roof panel 1 and the ceiling material 10 (when the roof is fully open), the wind 11 is caught between the roof panel 1 and the ceiling material 10. This is to prevent the windslop (air column sound) phenomenon caused by air pollution (see Figure 8).

In another conventional example shown in FIG. 9, a convex portion 13 is formed on the frame 12 in front of the roof opening 2 to define a drain portion 14.

<Problems to be Solved by the Invention> However, in such conventional technology, the frame 7 with the rail body 8 that partitions and forms the drain part 6 for the front side of the roof opening 2 and the frame 7 with the convex part 13 are not provided. frame 1 of
2 is fixed to the front side of the roof opening 2, each frame 7.12 protrudes into the roof opening 2 when the roof is fully opened, and the opening area of the roof opening 2 is reduced by that amount in the front part. It was damaged. In addition, when driving with the roof fully open, wind 11 enters the gap between the roof panel 1 and the ceiling material 10 and windslop occurs, so as a preventive measure, a seal rubber 9 is attached to the sunshade 4. I had to.

This invention was made by focusing on such conventional technology, and it does not damage the opening area of the roof opening when the roof is fully opened, and also prevents the wind from blowing even without providing a sealing member such as a sealing rubber. The present invention provides an automobile sunroof structure that can suppress the occurrence of wind slop caused by wind slop.

<Means for Solving the Problems> In order to achieve the above object, the automobile sunroof structure according to the present invention includes a cross-sectional groove that defines a drain section for the front side of the roof opening on the lower surface of the front end of the opening/closing lid. The shaped member is integrally attached to the entire width of the opening/closing lid.

<Function> According to the sunroof structure for an automobile according to the present invention, the groove-shaped cross-section member that defines the drain portion for the front side of the roof opening is fixed to the lower surface of the front end of the opening/closing lid. It slides back and forth with the opening/closing lid. Therefore, when the roof is fully opened, no member that defines the drain portion remains on the front side of the roof opening, and the opening area of the roof opening becomes large, approximately corresponding to the opening/closing lid.

In addition, since the groove-shaped cross-section member that defines the train section is fixed to the lower surface of the front end of the opening/closing lid over almost the entire width, the groove-shaped cross-section member is connected to the roof panel on the rear side of the roof opening and to the ceiling when the roof is fully opened. It acts as a lid to close the gap between the wood and the wood. Therefore, it is possible to prevent the windslop phenomenon during driving without having to take the trouble of attaching a sealing material as in the past.

Embodiment A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 5. Here, parts common to the conventional example are given the same reference numerals, and redundant explanations will be omitted.

On both left and right sides of the roof opening 2, there are a pair of rail bodies 20, 20 extending from the roof opening 2 to the rear side.
Alternatively, it can be attached to the lower surface of the side end of the roof panel 1. The rail body 20 is provided with a kite recess 22 for the sunshade 21 at the end on the side of the roof opening 2, and has a storage section on the opposite side for routing the cable 24 for operating the opening/closing lid 23. 25 is formed.

Moreover, this rail body 2. , fJ, there is a partition wall 27 erected approximately at the middle of the roof opening 2 for partitioning the train portion 26 at the side portion of the roof opening 2. Furthermore, this partition wall 2
7 also engages with a guide piece 28 attached to the lower surface of the side end of the opening/closing lid 23, thereby regulating the position of the opening/closing lid 23 in the left-right direction.

A motor 29 for driving the cable 24 is disposed below the roof panel l on the front side of the roof opening 2.

A frame 30.
31 is fixed over the entire width of the opening/closing lid 23, and defines respective drain portions 32, 33 on the front and rear sides of the opening/closing lid 23. In the front frame 30 according to the present invention, a horizontal mounting flange 30a formed on the rear side is integrally attached to a restraining member 34 for the welt 5 located on the lower surface of the front end of the opening/closing lid 23. There is. The lower surface of the frame 30 is attached to a finisher 36 via a spring-like finisher support member 35 provided over the entire width of the frame 30. Therefore, when the roof is fully closed, the height from the opening/closing lid 23 to the finisher 36 is equal to the height from the roof panel l to the ceiling material IO. When the roof is fully opened, a finisher support member 35 supporting the lower surface of the frame 30 is used to store the opening/closing lid 23 in the space between the roof hook 1 and the ceiling material 10.
By deforming the above-mentioned opening/closing lid 23, the height from the finisher 36 can be reduced. Moreover, since the frame 30 forming the front drain part 26 moves to the rear side together with the opening/closing lid 23, as shown in FIG. is almost covered over its entire width by the groove-shaped member. Therefore, even without using the conventional seal rubber 9, the wind 3
7 can be suppressed.

Rainwater W that has entered from the front and rear gaps in the gap between the opening/closing lid 23 and the roof opening 2 is drained from the drain part 32 defined by the front and rear frames 30 and 31. Flowing 33 degrees to the left or right,
It flows into the drain section 26 of the rail body 20 mentioned above. Then, these rainwater W is guided forward or backward to the drain hose 3 installed at the front and rear ends of the rail body 20.
It is designed to be discharged from 8.

In this manner, when the roof is fully opened, the frame 30 that defines the front drain part moves rearward together with the opening/closing lid 23, and the roof panel 1 is opened as shown in FIG.
and the ceiling material IO. Therefore, there is nothing blocking the front side of the roof opening 2, so the opening area increases and the sense of freedom increases significantly.

<Effects of the Invention> The automobile sunroof structure according to the present invention has the content as described above, and when the opening/closing lid is opened, the cross-sectional groove-shaped member for forming the drain section moves together with the opening/closing lid. Therefore, there is no member blocking the front side of the roof opening. Therefore, a wide opening area can be secured, and the feeling of freedom is significantly increased.

Furthermore, since the groove-shaped cross-sectional member serves as a lid between the roof panel and the ceiling material when the roof is fully opened, it is possible to suppress the occurrence of wind slop caused by wind during driving. Therefore, the conventional seal rubber is no longer necessary, and the number of parts and costs can be reduced.
