Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] <Industrial field of application> The present invention relates to a sunroof that can open and close an opening provided in a fixed roof of an automobile. The present invention relates to a drain structure for receiving water and draining it outside the vehicle.

<Prior Art> A movable panel made of glass, a steel plate or the like is slidably provided in an opening formed in a fixed roof of an automobile so that the opening can be opened and closed.
Movable roofs, so-called sunroofs, are well known.

An inner frame is fixedly installed inside the fixed roof in order to provide a mechanism for moving the movable panel up and down, a guide rail for guiding the sliding movement, and the like. A drain groove is provided as a water channel for receiving water droplets that enter the fixed roof from the gap between the movable panel and the movable panel and discharging the water droplets to the outside. The drain groove preferably connects the water channels extending to the left and right side portions of the fixed roof to each other so that the water can be appropriately drained even when the vehicle is rollingly inclined when turning, for example, the present application. Japanese Patent Application No. 62-057615 proposes a structure in which the rear ends of the left and right drain grooves are connected to each other by a vinyl hose or the like.

<Problems to be solved by the invention> However, according to the structure in which the left and right drain grooves are connected by a tube member such as a vinyl hose, the difference in cross-sectional area between the drain groove and the tube member tends to be too large.
Depending on the amount of water, the water does not flow smoothly into the tube member,
In some cases, it may not be possible to follow a sudden change in vehicle attitude, and water may overflow from the drain groove. In addition, since it is difficult to automate the hose connection work, the manufacturing process tends to be complicated.

The present invention has been made in view of the above problems, and its main purpose is to improve the connection between the drain grooves on the left and right without overflow and to simplify the manufacturing process. To provide a sunroof drain structure.

[Construction of the Invention] <Means for Solving the Problems> According to the present invention, such an object is provided on a steel plate inner frame provided inside a sunroof having an opening and closing opening. And a drain structure for receiving water from the opening and discharging the water to the outside of the vehicle.
Side water channels that extend in the vehicle front-rear direction and that are open upwards on both sides of the inner frame, and a connection portion that extends in the vehicle left-right direction at the rear portion of the inner frame and that connects to the side water channels is forward. This is achieved by providing a drain structure for a sunroof characterized in that a rear water channel having a closed cross section that opens toward the front is integrally formed of a synthetic resin material.

<Operation> According to such a configuration of the present invention, since the inner frame made of a steel plate having high rigidity is stacked, the rigidity of the constituent members of the water channel can be low. Therefore, as compared with the case where the frame is formed of only the synthetic resin material, it is easier to secure the rigidity, and thus the thickness is increased.
It does not need to be upsized. Also, if a waterway with a closed cross section is to be provided on a steel plate frame, a lid for closing the waterway must be welded, so it is necessary to take rust prevention measures on the members after welding, increasing the number of manufacturing steps. However, according to the present invention, such a problem can be avoided. Moreover, since the connection portion of the rear waterway to the side waterway is open toward the front, the upper surface is closed from the corner portion, so that the inflow from the side waterway to the rear waterway is smoothed, and The risk that the water that bounces off the part will overflow is greatly reduced. In addition, the inner frame can be formed separately, and since it is not necessary to form the inner frame over the entire circumference of the water channel, the weight can be reduced and the degree of freedom in designing the inner frame can be increased.

<Embodiment> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a main part of a movable roof to which the present invention is applied. An opening 2 having a substantially rectangular shape that is long in the left-right direction of the vehicle body is formed in the front portion of the fixed roof 1. This opening 2 can be complementarily closed by a movable panel 3 made of glass, for example. Has been done.

The movable panel 3 is guided by a pair of guide rails 4 extending in the vehicle front-rear direction at left and right positions inside the fixed roof 1 to completely close the opening 2 from the position toward the rear inner surface of the fixed roof 1. And is slidable in the front-back direction. In addition, a deflector blade 5 curved in an arc shape along the inner edge of the opening is provided at the front of the opening 2 so as to be able to move up and down according to the opening / closing operation of the movable panel 3.

On the other hand, as also shown in FIG. 2, a glass holder 9 is fixed to the inner peripheral edge of the movable panel 3 via seal members 7a and 7b and an adhesive 8. At the same time, panel stays 10 are hung vertically on both front lower surfaces of the glass holder 9. The panel stay 10 is formed into a substantially channel shape by bending the inside tip end thereof toward the outside after being hung down, and the slide shoe 6 made of, for example, a fluororesin or the like at the tip end portion 10a facing the outside. Is stuck.

A front end portion of the guide rail 4 that receives the slide shoe 6 and guides it in the front-rear direction is fixed to the inner frame 11 provided inside the fixed roof 1 via a guide rail stay 12. The guide rail stay 12 includes an engaging portion 13 that receives the front end portion of the guide rail 4 and a base portion 14 that is bolted to the inner frame 11, and is formed by, for example, zinc alloy die casting.

The inner frame 11 is formed by deep-drawing a steel plate, and has a relatively low outer peripheral wall 11 formed upright over the entire circumference.
A space S having an appropriate height dimension is formed between the corresponding position of the opening 2 of the fixed roof 1 and the position where the movable panel 3 is housed via the a, with the inner surface of the fixed roof 1. .

A drain member 16 is provided on the outer peripheral portion of the inner frame 11 which faces the fixed roof 1 and has U-shaped side water channels 15 extending in the front-rear direction on both left and right sides. It is set up. The drain member 16 is made of a synthetic resin material, and the outer peripheral edge portion thereof elastically and closely engages with the upper edge of the outer peripheral wall 11a of the inner frame 11, and the upper edge has a hollow cross section. The seal ridge 17 forming the is formed over the entire circumference. This seal ridge 17 is fixed roof 1
When the inner frame 11 is fixed to the inner surface of the, the inner surface of the fixed roof 1 is brought into liquid tight contact with the inner surface of the fixed roof 1.

As also shown in FIG. 3, the front portions of the left and right side water channels 15 extend inward in the vehicle width direction along the front edge of the opening 2 and are connected to each other. At the same time, in this portion, a widened portion 16W is formed further inside the side water passage 15 so as to form a storage portion for the deflector blade 5. Then, in order to prevent water droplets from entering the passenger compartment, the rising wall 16 is provided along the inner peripheral edge of the widened portion 16W.
a is extended.

By the way, the engaging portion 1 of the guide rail stay 12 described above.
A gripping piece 18 for gripping the rising wall 16a is formed on the outer side wall of No. 3 so as to ride over the rising wall 16a. The gripping piece 18 prevents the widened portion 16W of the drain member 16 from being lifted up on the inner peripheral side. Further, a projecting piece 18a is provided on the outer surface of the gripping piece 18 in a perpendicular direction, and an engaging hole 19 for fixing the supporting device of the deflector blade 5 is formed at the projecting end thereof.

Incidentally, the deflector device including the deflector blade 5 is not directly related to the essence of the present invention, and therefore its detailed description is omitted.

The rear ends of the right and left side water channels 15 whose upper surfaces are open are connected to each other by a hollow rear water channel 20. The connection portion J between the side water passage 15 and the rear water passage 20 is somewhat curved and smoothly continues, and its upper surface is closed from the rear end portion 15a of the side water passage 15, that is, in the rear water passage 20. The connection portion with the side water channel 15 at the side is open toward the front. As shown in FIG. 4, the cross-sectional area of the portion that transitions to the rear water channel 20 is gradually changed. In this embodiment, the rear water channel 20 side is made smaller. The cross-sectional area is used.

A drain port 21 is provided in a radial direction at each corner of the drain member 16 configured as described above (FIG. 5), and a vinyl tube or the like (not shown) along the pillar is provided. By connecting to the drainage port 21, it is possible to drain the water to the outside of the vehicle.

In this way, the water flowing backward in the side water passage 15 smoothly flows into the connection portion J where the cross-sectional area of the water passage gradually decreases, and then flows out to the outside through the drain port 21 projecting in the same portion. To do. Then, the water that cannot be completely drained from the drain port 21 on the upper side due to the inclination of the vehicle body or the like is drained from the other drain port 21 located on the lower side via the rear water channel 20.

The drain member 16 described above is formed by an appropriate method such as pultrusion molding, injection molding, blow molding, or the like, and then integrated by vulcanization adhesion.

[Effects of the Invention] As described above, according to the present invention, the manufacturing process can be mechanized because it can be manufactured without manual labor.
A great effect can be achieved in promoting automation. In addition, the inflow and outflow of water between the opened side water channel and the closed rear water channel becomes smooth, and at the same time it is possible to suitably prevent water from overflowing from this connecting portion,
The effect is extremely large because the improvement of drainage performance can be planned.
