Description

[Detailed description of the invention] (Field of industrial application) This invention is a sliding roof in which an opening formed in the body roof of a vehicle is opened and closed by a sliding panel. Regarding the drainage channel structure of riding roof housing.

(Prior art and its problems) Fig. 3 shows a plan view of a vehicle equipped with this type of sliding roof, and Fig. 4 shows A of Fig. 3.
-A cross-sectional view is shown. In FIGS. 3 and 4, the sliding roof is the vehicle body roof 1.
A sliding panel 3 is supported on a sliding roof housing (hereinafter also referred to as a housing) 2 arranged at the lower part of the body so that it can move back and forth, and an opening 4 formed in a part of the vehicle body roof 1 is inserted into the sliding panel 3. It is configured to open and close. As shown in FIG. 4, guide rails 5 are provided on both sides of the housing 2, and guided by the guide rails 5, the sliding panel 3 is driven forward and backward by a drive cable (not shown). An opening 6 is formed on the front side of the housing 2 facing the opening 4 of the vehicle body roof 1, and the rear side is configured to serve as a storage area for the sliding panel 3 and a separately provided sunshade 7 that is slidably provided. has been done. Furthermore, a drainage channel 8 is formed on the outer periphery of the housing 2 to receive rainwater that enters the inside of the vehicle from between the sliding panel 3 and the opening 4, and to discharge it to the outside of the vehicle from a drain hose (not shown). , drain 8
It is separated from the inner region by a bead 9 integrally formed on the housing 2.

By the way, in the conventional drainage channel structure of the housing 2 of this type, at the rear corner of the housing 2, as shown in FIG. A corner bead 9c that extends diagonally toward the rear end of the vertical bead 9b along the horizontal bead 9a connects the horizontal bead 9a and the vertical bead 9b.
The corner portion of the drain channel 8 having the drain port 10 is partitioned from the inner area of the housing 2 by 9b and 9c.

However, with the above-mentioned drainage channel structure, when the vehicle suddenly starts, the water accumulated in the drainage channel 8 is
As shown by the dashed line in the figure, there is a problem in that the water is pushed back at the corner of the drainage channel 8, overcomes the corner bead 9c, overflows into the interior area, and enters the interior of the vehicle through the opening 6 of the housing 2. In particular, since the bead 9 is integrally formed with the housing 2 by press molding or the like, the corner bead 9c has an R shape as shown in FIG. The risk of water overflowing over the bead 9c becomes even higher.

Therefore, as a measure to prevent water from overflowing from the corner bead 9c, for example, as shown in FIG. 7, a separate member having an S-shaped cross section is welded to the corner bead 9c' of the housing 2. If the upper end of the corner bead 9c' is bent, water can be effectively prevented from getting over the corner bead 9c' as shown by the dashed line in the same figure. This causes problems such as the manufacturing of the housing 2 becoming complicated due to its attachment.

(Purpose of the invention) This invention was made in order to solve the above-mentioned problem.The purpose of this invention was to solve the problem described above. To provide a drainage channel structure for a sliding roof housing that can reliably prevent water from overflowing into a vehicle interior with a simple configuration.

(Means for achieving the object) In order to achieve the above object, the drainage channel structure of the sliding roof housing of this invention supports the sliding panel that opens and closes the opening formed in the vehicle roof, and At the rear corner of a sliding roof housing that has a drainage channel separated by a bead, from one end of the horizontal bead along the rear edge of the sliding roof housing to the rear end of the vertical bead along the side edge of the sliding roof housing. The rear end of the vertical bead is extended to the outside of the corner bead, and one end of the horizontal bead is extended to the outside of the rear end of the vertical bead. A maze is formed at the corner of the drainage channel, and the maze is configured to suppress the force of water that tends to overflow from the corner.

(Example) Fig. 1 shows a plan view of the rear half of a sliding roof housing to which an embodiment of this invention is applied, and Fig. 2 is an enlarged plan view of the part surrounded by the dashed line in Fig. 1. shows.

In this housing 12, at the rear corner of the drainage channel 18, which is provided by forming a recess on the outer periphery, the housing 12 is diagonally directed from one end of the horizontal bead 19a to the rear end of the vertical bead 19b, as shown in FIG. A part 19b' of the rear end of the vertical bead 19b is formed to extend outside the corner bead 19c connecting the horizontal bead 19a and the vertical bead 19b, while one end of the horizontal bead 19a is connected to the vertical bead 19b. By extending the rear end part 19b' to the outside,
The drainage channel 18 is configured to form a zigzag maze in the direction from its rear corner toward the corner bead 19c. Note that FIG. 1 shows a state in which the guide rail 15 is installed on the vertical bead 19b, and FIG. 2 shows a state in which the guide rail 15 is omitted. A drain port 20 is provided at each corner of the drain channel 18.
The water accumulated in the tank is drained from the drain port 20 to the outside of the vehicle via a drain hose (not shown).

In the drainage channel structure of the sliding roof housing 12, when the vehicle suddenly starts, the standing water in the drainage channel 18 is pushed back at the corner of the drainage channel 18, as shown by the dashed line in FIG. When the water tries to flow toward the corner bead 19c, the force of the water flows through the horizontal bead 19a, the vertical bead 19b and a portion 19b', and the corner bead 1.
It is attenuated by the zigzag maze formed by 9c. Therefore, it is possible to reliably prevent water from overflowing over the corner bead 19c and overflowing into the inner area of the housing 12.
This prevents water from entering the vehicle through the opening 16.

(Effects of the invention) As described above, according to the drainage channel structure of the sliding roof housing of this invention, even if the accumulated water in the drainage channel of the housing is pushed back at the rear corner due to a sudden start of the vehicle, etc. The simple structure of the labyrinth formed at the corner sufficiently reduces the force of water that tends to overflow from the drainage channel, thereby achieving the effect of reliably preventing water from entering the interior of the vehicle.
