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 sectional view is shown, and FIG. 5 is a rear half plan view of the sliding roof housing. Figure 3,
In FIGS. 4 and 5, the sliding roof has a sliding panel 3 supported on a sliding roof housing (hereinafter also referred to as housing) 2 arranged at the lower part of the vehicle body roof 1 so as to be able to move back and forth. The opening 4 formed in a part of the vehicle body roof 1 is configured to be opened and closed by the sliding panel 3. 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 sunshield 7 that is slidably provided. has been done. Furthermore, a drainage channel 8 is recessed on the outer periphery of the housing 2 to receive rainwater that enters the inside of the vehicle through the gap between the sliding panel 3 and the opening 4. It is partitioned off by a bead 9 formed integrally with 2. Further, as shown in FIG. 5, drain ports 10 are provided at each corner of the drain channel 8, and water accumulated in the drain channel 8 is discharged from the drain ports 10 to the outside of the vehicle via a drain hose (not shown). ing.

By the way, in the conventional housing 2 of this type, as shown in FIG. 5, the bottom surface of the drainage channel 8 extending along the outer periphery is made flat (see FIG. 4), so that it does not occur when the vehicle suddenly starts. In this case, the drainage canal 8
The standing water flows forcefully into the rear side of the drainage channel 8 from the left and right. The surging water is marked by the arrow P in Figure 5.
(Here, water is shown flowing in from the right side, but the same is true for the left side). As shown by Q, there was a problem in that the water got too strong and overflowed over the bead 9 and overflowed into the inner area of the housing 2, and the water entered the vehicle interior through the opening 6 at the front of the housing 2.

(Purpose of the invention) This invention was made in order to solve the above problem.In the sliding roof housing that supports the sliding panel of the sliding roof, standing water in the drainage channel is removed from the housing when the vehicle suddenly starts. To provide a drainage channel structure for a sliding roof housing that can prevent water from overflowing into the interior of a vehicle and intruding into a vehicle interior.

(Means for Achieving the Object) This invention is a drainage channel structure of a sliding roof housing that supports a sliding panel that opens and closes an opening formed in a vehicle roof, and has a drainage channel on the outer periphery. In order to achieve this purpose, a plurality of discontinuous protrusions are provided on the bottom of the drainage channel all around the drain, and each protrusion is integrally formed so that a part of the bottom is raised. By suppressing the flow rate of water accumulated in the drainage channel during a sudden start, etc., the protrusion is configured to prevent water from overflowing from the drainage channel.

(Embodiment) FIG. 1 is 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 a sectional view taken along the line BB in FIG. 1. As shown in both figures, the housing 11 is provided with a plurality of discontinuous protrusions 13 over the entire area on the bottom surface of a drainage channel 12 which is recessed along the outer circumference thereof. As shown in FIG. 2, this protrusion 13 is integrally formed with the drain channel 12 so that a part of the bottom surface of the drain channel 12 is raised in a mountain shape. It is designed to reduce the flow rate of water. The rest of the configuration is the same as that of the prior art described above, so the same parts are given the same reference numerals and the explanation thereof will be omitted.

The above sliding roof housing 12
According to the drainage channel structure, since the protrusion 13 is protruded from the bottom of the drainage channel 12, standing water in the drain channel 12 can flow from the left and right when the vehicle starts suddenly.
Even if the water tries to flow forcefully toward the rear side, the flow velocity of the water is suppressed by the protrusion 13, and as a result,
Since a rapid rise in water level is suppressed in the drainage channel 12 at the rear of the housing 11, water in the drainage channel 12 will not overcome the bead 9 and overflow into the inner area of the housing 11. In addition, drainage channel 1
Naturally, the force of the water hitting the corner part 2 also becomes weaker, and the water pushed back at the corner part does not overflow over the bead 9a and overflow into the inner area of the housing 11. In this way, a situation where standing water in the drainage channel 12 enters the vehicle interior can be avoided.

In addition, since a part of the bottom surface of the drainage channel 12 is raised like a mountain and each protrusion 13 is integrally formed over the entire circumference of the drainage channel 12, the rigidity of the drainage channel 12 can be improved and the strength In addition, the cost can be reduced compared to the case where a separate protrusion is separately produced and provided on the bottom surface of the drainage channel 12.

(Effect of the invention) As described above, according to the drainage channel structure of the sliding roof housing of this invention, a plurality of discontinuous protrusions provided on the bottom surface of the drainage channel along the entire circumference prevents the drainage channel from pooling. The water flow rate is suppressed, so even if the vehicle suddenly starts, the standing water that hits the corner of the drainage channel and is pushed back will not overflow into the inner area of the housing, or the standing water will suddenly rise in water level and cause the drainage channel to collapse. This has the effect of reliably preventing a situation where the liquid overflows and enters the vehicle interior. In addition, the bottom of the drainage channel is partially raised and each projection is integrally formed around the entire circumference of the drainage channel, which improves the rigidity and strength of the drainage channel. The cost can be reduced compared to the case where the section is manufactured separately and installed on the bottom of the drainage channel.
