Abstract

PROBLEM TO BE SOLVED: To prevent a lip section from falling to the inside at the corner section of a sunroof seal. SOLUTION: A sunroof seal 15 for securing the water-tightness with an opening is fitted to the peripheral edge section of a moving panel 3 for opening/ closing the opening formed on the roof 1 of a vehicle, and the waterdrops infiltrating from between the moving panel 3 and the opening are dropped to a drain gutter 13 formed on the side section frame 4 of a sun roof by a lip section 15b integrally molded on the sunroof seal 15. A guide plate 17 kept in contact with the face of the lip section 15b on the center side of the opening is fixed to a reinforcing panel holder 16. The deformation of the lip section 15b toward the center side of the opening generated by the peripheral length difference between the corner section inside portion of the seal main body 15a of the sunroof seal 15 and the lip section 15b at the corner section of the moving panel 3 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof drainage structure for preventing water from leaking from an opening of a sunroof device in which an opening formed in a roof of a vehicle can be opened and closed by a slide panel.

[0002]

2. Description of the Related Art Conventionally, there is a sunroof apparatus in which an opening is formed in a roof of a vehicle such as an automobile and a slide panel for selectively opening and closing the opening is provided.
-36661. This sunroof device has a structure in which a lip portion for guiding water droplets is provided on a sunroof seal attached to a peripheral edge of a sunroof panel, and the lip portion faces a drain groove formed in a sunroof frame. This makes it possible to guide water droplets entering from between the sunroof panel and the opening of the vehicle to the drain grooves of the sunroof frame without entering the guide rails and the vehicle interior.

[0003]

However, in the prior art as described above, when the sunroof seal is attached to the peripheral edge of the sunroof panel, the sunroof seal is located inside the corner of the seal body at the corner of the sunroof panel. Since there is a difference in circumferential length between the portion and the lip portion located on the outside, the tip of the lip is deformed so as to be inclined toward the inside of the corner portion. The deformation may cause the tip of the lip to be positioned on the guide rail, and in the worst case, water droplets may fall into the guide rail and further into the vehicle interior. In order to avoid such a situation, the drain groove of the sunroof frame may be set wider, but in this case, there is a problem that the opening area on the vehicle compartment side is reduced.

[0004]

SUMMARY OF THE INVENTION In order to solve such a problem, a sunroof seal attached to the peripheral edge of a sunroof panel falls inside the tip of the lip due to a difference in peripheral length between the seal body and the lip at the corner. In the present invention, a sunroof seal is provided at a peripheral portion of a movable panel for opening and closing an opening formed on a roof of a vehicle so as to ensure watertightness between the opening and the opening. A sunroof drainage structure integrally formed with a lip portion for dropping water droplets entering from between the movable panel and the opening into a drainage groove of a sunroof frame, wherein the lip portion is directed toward the center of the opening. In order to prevent deformation, a guide plate is provided near the peripheral edge of the movable panel, the guide plate being in contact with a surface of the lip facing the center of the opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to specific examples shown in the accompanying drawings.

FIG. 1 shows an outline of an automobile sunroof apparatus to which the present invention is applied. The roof 1 of the vehicle is formed with a substantially rectangular opening 2 having a long side in the width direction of the vehicle body. The opening 2 is complementarily closed or opened by a movable panel 3 made of, for example, sheet glass. I am getting it. Since the members constituting the present invention are disposed substantially symmetrically with respect to the center line along the front-rear direction of the vehicle, the positional relationship below is based on the center of the vehicle compartment unless otherwise specified. This will be explained.

As shown in FIG. 1, stays 3 extending in the front-rear direction are provided on both left and right end portions of the inner surface of the movable panel 3.
are fixed, and a slider 3b mounted on the lower end of the stay 3a is slidably engaged with a guide rail 4a formed on the side frame 4. A distal end of a push-pull cable 6 as a driving force transmission cable is connected to the slider, and a proximal end of the push-pull cable 6 is connected to a drive shaft of a speed reducer 9 integrated with a motor 7 by a rack-and-pin. It is meshed in a pinion shape. The movable panel 3 is driven to open and close by pushing and pulling the push-pull cable 6.

[0008] At the intermediate portions of the two side frames 4,
Both ends of an intermediate portion reinforcing stiffener 8 fixed to the inner surface of the roof 1 are connected to each other. The motor 7 is disposed between the two free ends of the opposite side frames 4 opposite to the front frame 5. A reduction gear 9 is integrated with the motor 7, and constitutes a motor device together with a motor mounting bracket 10 that supports them. The motor mounting bracket 10 is fixed to the inner surface of the roof 1 by screws.

Next, the drain structure of the sunroof configured as described above will be described below with reference to FIG. FIG. 3 is a partially enlarged sectional view taken along the line III-III in FIG.

As shown in FIG. 3, the guide rail 4a has a T-shaped cross section standing on the bottom wall of the side frame 4 and extends in the vehicle front-rear direction. The side frame 4 is formed with a ridge 4b parallel to the guide rail 4a, and the ridge 4b is provided with a cable guide groove 4c for guiding the push-pull cable 6. A slider guide groove 11 is formed between the guide rail 4a and the ridge 4b, and the slider 3b is guided by the slider guide groove 11. A portion of the guide rail 4a facing the indoor opening 12 guides a sunshade stay (not shown).

The outer side of the side frame 4 is formed in a crank shape so as to be one step higher than the bottom surface provided with the guide rails 4a and the ridges 4b. Outer wall 4d parallel to the ridge 4b
Is provided, and a drain groove 13 is formed between the outer wall portion 4d and the ridge portion 4b.

Although FIG. 3 shows the rear side of the movable panel 3, the rear part of the movable panel 3 is designed to receive water droplets entering from a gap between the rear edge of the movable panel 3 and the opening 2. A drain channel 14 extending in the vehicle width direction is provided. This drain channel 14
Is provided so as to cover above the guide rail 4a and the slider guide groove 11 at a portion corresponding to the corner portion of the movable panel 3, and the movable panel 3 is viewed from a plan view.
This prevents water drops from the corners of the movable panel 3 from falling into the guide rails 4a and the slider guide grooves 11 at the portions where the corners of the movable panel 3 cross the guide rails 4a.

A sunroof seal 15 formed by, for example, rubber extrusion molding is attached to the periphery of the movable panel 3. A frame-shaped reinforcing panel holder 16 provided around the entire periphery of the movable panel 3 is fixed, for example, by bonding, and a sunroof seal 15 is supported by the panel holder 16. The sunroof seal 15 is also provided on the entire periphery of the movable panel 3. Sunroof seal 15 provided in this manner
When the movable body 3 is fully closed with the seal body 15a
And the gap between the periphery of the movable panel 3 and the opening 2 is sealed in a watertight state.

The sunroof seal 15 is integrally formed with a lip 15b extending downward from the seal body 15a. The lip portion 15b is formed so as to substantially hang down in a normal mounting state, and the seal body 15a
Lip 15b
Can be dropped almost directly below the tip.

A guide plate 17 is fixed to the lower surface of the panel holder 16.
7 is formed so as to extend from the fixed portion so that one end of the lip abuts on the surface of the lip portion 17b facing the center of the opening 2.

Normally, one sunroof seal 15 is mounted over the entire periphery of the movable panel 3, and in this case, the peripheral length is provided between the inside of the corner portion of the seal body 15a and the lip portion 15b at the corner portion. A difference occurs, and the lip portion 15b is deformed in a direction inclining toward the center of the opening 2;
7 is provided to prevent deformation of the lip 15b. Therefore, even in the corner portion, the lip portion 15b
Is held in a substantially hanging state.

Thus, in the straight portion of the movable panel 3, the lip portion 15b is located at a predetermined position above the drain groove 13 as shown by the imaginary line in FIG. The lip portion 15b is held in contact with the guide plate 17 so that the lip portion 15b is in the same hanging state as the linear portion. For this reason, the tip of the lip portion 15b is always located at a predetermined position, and it is possible to preferably prevent a problem that a water drop falls to an unexpected place and, in the worst case, a water drop falls into a vehicle interior. The water droplets fall on the drain channels 14 at the corners of the movable panel 3 and then flow down to the drain grooves 13, and fall into the drain grooves 13 at the left and right side edges of the movable panel 3. The water is discharged out of the vehicle through drain tubes connected to both ends of the drain groove 13 in the axial direction.

In the illustrated example, the sunroof seal 1 is used.
Although the example in which the guide plate 17 attached to the panel holder 16 is provided separately from the structure 5 is shown, the extension end of the guide plate 17 is not limited to this structure, and the lip portion 15 may be used.
b may be integrated by, for example, insert molding.
By doing so, the rigidity of the lip 15b can be further increased, and the positional accuracy of the tip of the lip 15b can be improved.

In the illustrated example, the rear corner of the movable panel 3 is shown, but the same applies to the front corner. In this embodiment, a slidable structure is shown as the movable panel of the sunroof. However, the present invention can be applied to a tiltable structure. In these cases, the same effects as those described above can be obtained.

[0020]

As described above, according to the present invention, in the corner portion of the movable panel of the sunroof, there is a difference in circumferential length between the inner portion of the corner portion of the sunroof seal mounted on the peripheral portion of the movable panel and the lip portion. The lip can be prevented from inclining and deforming inside the corner, and the inclination of the lip can be kept constant. The water drop can be dropped to the place, and the width of the drain groove of the sunroof frame can be reduced by increasing the accuracy of the water drop drop position, so that the indoor opening can be enlarged.
