Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a rear drain structure for a sunroof for an automobile.

Prior art Fig. 1 shows an example of a sunroof type automobile.This sunroof type automobile has an opening 2 formed in the front side of the roof 1, and a connection between the opening 2 and the inside of the roof 1. A sunroof lid 3 is provided that slides in the longitudinal direction of the vehicle body. By sliding the sunroof lid 3 rearward along the inside of the roof, a feeling of openness is obtained, and lighting is increased to improve the interior of the vehicle. This is to improve the atmosphere. A weather strip 4 is attached to the periphery of the sunroof lid 3, and the weather strip 4 comes into close contact with the periphery of the roof opening 2 when the lid 3 is closed. ,
Since it is directly hit by rainwater and washing water, it is not possible to completely prevent water from entering the interior of the vehicle. Therefore, the water that penetrates the close contact area between the both side edges and the front edge of the roof opening 2 and the weather strip 4 and enters the inside of the vehicle is removed by the sunroof frame placed below the roof 1 as shown in FIG. 5 is received by the drip channel section 6 formed in the section 5, and drained out of the vehicle through the entire drain pipe 7, and water that penetrates the close contact area between the rear edge of the roof opening 1 and the weather strip 4 and enters the inside of the vehicle. For ζ, for example, Jikko 58-168
By adopting a rear drain structure as shown in No. 94, water is guided to drip channel portions 6 on both sides of the sunroof frame 5, and similarly drained to the outside of the vehicle via drain pipes 7.

As shown in FIG. 3, this rear drain structure has a step 10 on the lower side of the rear end of the sunroof lid 3, specifically on the girder rain force 8, and has a step 10 between the rear edge of the lid 3 and the rear edge of the roof opening 2. A sealing material support plate 9 extending under the roof 1 across the joint part is fixed by spot A contact or screws 11, and the end of this plate 9 is attached to the lower surface of the roof near the rear edge of the roof opening, specifically. roof reinforcement 1
A sealing member 15 having a sealing lip 14 in close contact with 2
It is fixed. According to this rear drain structure, the joint part between the rear edge of the lid 3 and the rear part of the roof opening 2, that is, the close contact part between the weather strip 4 and the roof molding [6] attached to the periphery of the roof opening is penetrated and The step 10 of the plate 9 receives water entering the interior of the vehicle, and the seal lip 14 prevents water from entering the passenger compartment due to its close contact with the roof reinforcement [2]. Sunroof frame 5 shown in FIG. 2 from both sides of plate 9
This guides drainage to the drip channel portions 6 on both sides.

However, in such a conventional structure, when the vehicle suddenly starts or brakes, the water that has flowed down to the stepped portion 10 swings and overcomes the front of the stepped portion 10, causing the plate 9 to come into contact with the weather strip support frame 4a. 1 as shown by the arrows in FIG.
There was a risk that it might get inside the room.

Purpose of the Invention In view of the conventional situation, the present invention has been developed to prevent water from entering through the joint between the rear edge of the sunroof lid and the rear edge of the roof opening.
It is an object of the present invention to provide a rear drain structure for an automobile sunroof that can reliably guide drainage without intruding into the passenger compartment.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a sealing material supporting plate disposed below the rear end of the sunroof lid, and a sealing material support plate having a sealing member at one end that is in close contact with the lower surface of the roof near the rear edge of the roof opening. It is integrally provided with a seal lip and a second seal lip that is in close contact with the lower surface near the rear edge of the lid at the other end, and when the lid is closed, these il, g2 A sealing member that forms a drip channel portion between the sealing lip and the sealing lip is firmly attached.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals assigned to the same parts as in the conventional structure.

That is, in the present invention, as shown in FIG.
The sealing material support plate 9 located on the lower side of the roof 1 is spot welded or straddles the joint between the back cover and the back of the roof opening 2, and the close contact area between the weather strip 4 and the molding 16A. The roof reinforcement 1 in the vicinity of the roof opening rear mount is placed on one end of the sealing material support plate 9, specifically on the stepped portion 10.
A first seal lip 21 that is in close contact with two surfaces, and a second seal lip 22 that is in close contact with the reinforcement surface 8 near the rear edge of the lid 3 are integrally provided at the other end. 1st. second seal lip 21,
A sealing member 20 constituting a drip channel portion 23 is fixed between the drip channel portion 22 and the drip channel portion 23 . This sealing member 20 is fixed on the step portion 10 in contact with it or fixed with screws, but
Preferably, as shown in the figure, a sandwiched layer cap 24 having a substantially U-shaped cross section is formed at the end of the first seal lip 21, and this sandwiching portion 24 is separated from the plate 9 terminal to form a sealing member from the plate 9 terminal side. It is preferable to prevent the peeling of 20. Further, by arranging the general part of the sealing member in close contact with the lower edge of the weatherstrip 4 as shown in the figure, a double seal structure can be obtained between the weatherstrip 4 and the second seal lip 22. Therefore, the sealing effect can be further enhanced as will be described later. If the third seal lip 35 or the like is formed, the effect will be more reliable.

According to the structure of the above actual case, the lid 3 has a weather strip 4 that cannot be used, and the roof and opening 2 have a molding 16 that cannot be used.
The water that penetrates into the storm room 11)u through the close contact area is received by the drip channel part 23 of the sealing member 20, and the water is received by the drip channel part 23 of the sealing member 20, and the second water flows along the drip channel part 23 from both sides of the drip channel part. Drainage is guided to drip channel portions 6 on both sides of the sunroof 7 frame 5 shown in the figure. Here, when the vehicle is suddenly started or braked, the water that has flowed down into the drip channel section 23 swings particularly greatly, but this flow is separated by the general section of the seal member 20, the first seal lip 21°, and the second seal lip 22. It only takes place within the drip channel section n. Above all,
When the lower edge of the weather strip 4 is in close contact with the general portion of the seal member 20 as in this embodiment, the flowing water only moves between the first seal lip 21 and the weather strip 4. Moreover, the first seal lip 21 is in close contact with the lower surface of the roof, specifically, the main lip 21a of the first seal lip 21 formed in a V shape is in close contact with the lower surface of the molding 16A, and the sub lip 211) is in close contact with the surface of the roof trim 17. Since the first seal lip 21 is sealed at 2M, water will not enter the inside of the vehicle interior beyond the entire first seal lip 21.

Furthermore, even if a gap is partially formed between the weather strip 4 and the sealing member 20 due to an assembly error or a molding error of the weather strip 140, the second seal lip 22 is attached to the rear of the lid 3. Since it is in close contact with the bottom surface of the end, does water flow toward the joint between the plate 9 and the lid reinforcement 8? iit leakage is completely prevented, so that the I! It is possible to completely prevent water from entering the fenced house.

Effects of the Invention As described above, according to the present invention, the sealing member-
Since the drip channel is composed of the crotch, a first seal lip that is in close contact with the lower surface of the roof, and a second seal lip that is in close contact with the lower surface of the rear end of the lid, the fluid movement during starting and braking of one vehicle is carried out through this drip channel. It is regulated only within the department, and the '1. Since the second seal lip ζ can prevent water from leaking outside the drip channel, it is possible to reliably prevent water from entering the interior of the vehicle, further improving reliability9 quality. It has a great effect.
