Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sunroof device, and more particularly to a rain gutter portion for flowing water droplets entering from an opening of a vehicle roof.
[0002]
[Prior art]
As a conventional sunroof device, there is a technique disclosed in Japanese Utility Model Laid-Open No. 62-131923. This gazette includes a frame that is provided below the opening formed in the vehicle roof, receives a water drain from the opening of the vehicle roof, and a frame that forms a rain gutter at the periphery of the opening, and between the frame and the vehicle roof. A sunroof device is disclosed that includes a welt seal provided with an inner lip portion extending along the frame toward the inside of the frame.
[0003]
In such a configuration, for example, when the vehicle body is on a flat horizontal surface and the speed of water droplets flowing through the rear drain is relatively slow, the water droplets entering from the opening are set to fall from the rear drain into the rain gutter of the frame. . Also, when the vehicle body is tilted due to road surface conditions or running conditions, the speed of water droplets flowing through the rear drain increases, and the water droplets do not flow into the rain gutters of the frame but scatter toward the side of the frame and jump over the gutters. However, in the above-mentioned conventional device, a water droplet that jumps over the rain gutter is installed by installing a welt seal between the vehicle roof and the frame. The water droplets are absorbed by the welt seal and the water droplets are prevented from falling outside, thereby preventing the water droplets from splashing outside regardless of the state of the vehicle body.
[0004]
[Problems to be solved by the invention]
However, in the configuration of the above-mentioned conventional device, a welt seal made of a separate member is newly required as a configuration for preventing water droplets falling from the rear drain to the rain gutter of the frame from jumping over the gutter and scattering outside. There is a problem that the number of parts increases and the number of manufacturing steps and costs increase.
[0005]
Therefore, in order to solve the above-described problems, it is a technical object of the present invention to provide a sunroof device that can prevent water droplets from splashing outside without increasing the number of parts.
[0006]
[Means for Solving the Problems]
The technical means taken in the present invention in order to solve the above technical problem is that the second gutter member extends along the rear end of the movable panel and has a gap at the end in the left-right direction of the movable panel. And a pair of standing walls that are formed integrally with the end through the gap and face each other in the left-right direction of the movable panel ,
An end portion of the standing wall facing the end portion in the vertical direction of the movable panel is disposed on the gap, and the gap, the standing wall, and the bottom surface are integrally formed .
[0007]
According to the above technical means, when the speed of a water droplet that enters from the opening and flows in the second rain gutter member is equal to or lower than a predetermined speed, the water droplet flows down from the end of the second gutter member into the first rain gutter portion. When the speed of water droplets flowing in the second gutter member is sufficiently high, the water droplets in the second gutter member do not flow directly from the end of the second gutter portion into the first gutter portion, but once hit the standing wall. To the first gutter part. Therefore, according to the configuration of the present invention, since the standing wall is formed integrally with the second gutter member, the water droplet is guided into the first gutter portion regardless of the speed of the water droplet in the second gutter member. It is possible to prevent water droplets from splashing outside without increasing the number of parts.
[0008]
Preferably, when the standing wall has a portion whose upper side is inclined toward the inner side in the left-right direction of the movable panel with respect to the lower side, water droplets directed toward the standing wall are surely guided into the first rain gutter portion. .
[0009]
As a specific configuration of the second gutter member, for example, the second gutter member, said bottom surface and said continuously from the standing wall are formed integrally pairs Oite opposed to the opening and closing direction of the movable panel A configuration having a side wall is conceivable.
[0010]
More preferably, together with the bottom surface has an extending portion extending downward at the boundary between the gap and the vertical wall is to be formed to substantially the same position as the bottom of the extending portion, the bottom surface Both the water droplets flowing through and the water droplets flying toward the standing wall are guided downward, and the water droplets are reliably guided into the first gutter member.
[0011]
Embodiment
Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the sunroof device is disposed in the front and rear direction (up and down direction in FIG. 1) on both edges of the opening 2 and the movable panel 5 that opens and closes the opening 2 of the vehicle roof 1. A pair of guide rails 3 formed integrally with the flange member and the movable panel 5 are disposed along the rear edge of the movable panel 5 and the end of the opening 2 in the left-right direction is located above the guide rail 3. And a rain channel 7 as a second gutter member. A movable panel 5 is supported on the guide rail 3 via a known link mechanism 4 so as to be slidable in the vehicle front-rear direction. A resin-made front frame 6 is disposed at the front edge of the opening 2, and both guide rails 3 are connected to the front frame 6 by tapping screws. Further, a well-known drive mechanism 9 is fixed to the front frame 6, and this drive mechanism 9 is linked to each link mechanism 4 via a cable (not shown). As is well known, the cable is toothed and is slidably guided in the pipe 8 and the guide rail 3.
[0012]
In the configuration described above, when the drive mechanism 9 is operated in one direction, the movable panel 5 slides in the vehicle rear direction via the cable and the link mechanism 4 and the opening 2 is opened. When the drive mechanism 9 is operated in the other direction, the movable panel 5 slides in the vehicle front direction via the cable and the link mechanism 4 and the opening 2 is closed.
[0013]
2 is an enlarged perspective view of a portion A in FIG. 1, FIG. 3 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 4 is a cross-sectional view taken along line CC in FIG. As shown in FIGS. 2 to 4, in the present embodiment, both guide rails 3 include a guide portion 31 that extends in the rail longitudinal direction where the movable panel 5 is slidably supported, and the opening portion 2 is in a closed state. In the guide rail 3, the rain gutter 32 extending in the longitudinal direction of the rail is arranged below the boundary between the roof panel 1 and the movable panel 5 (under the side edge of the opening 2). A gutter member is integrally formed. The guide portion 31 is integrally formed with a groove portion 31a for slidingly guiding the link mechanism 44 and a groove portion 31c for slidingly guiding a sunshade panel (not shown). The rain gutter part 32 has a substantially U-shaped cross section, and a flange part 32b serving as an attaching part to the roof panel 1 and a groove part 32d for slidingly guiding the cable are integrally formed on one side wall 32a. The guide portion 31 and the gutter portion 32 are integrated so that the guide portion 31 is located on the inner side in the vehicle width direction than the gutter portion 32. The guide rail 3 configured in this way is made of aluminum and is formed by extrusion molding.
[0014]
The rain channel 7 is connected to the link mechanism 4 via a rod 75 and moves in the front-rear direction in conjunction with the sliding operation of the movable panel 5. The rain channel 7 includes a pair of side walls 71a and 71b facing each other in the opening / closing direction of the movable panel 5, a bottom surface 72 connecting the pair of side walls 71a and 71b, and a gap 74 between the pair of side walls 71a and 71b and the bottom surface 72. And an upright wall 73 formed continuously from the end of the side wall 71b and a part of the bottom surface 72. In view of the function of the rain channel 7, the side wall 71a on the vehicle front side is configured to be lower than the side wall 71b on the vehicle rear side. The standing wall 73 is inclined inward in the left-right direction of the movable panel 5 (leftward in FIG. 2) as it goes from the lower side to the upper side, and the uppermost end of the standing wall 73 is bent inward. . Further, the standing wall 73 is configured to be lowered from the rear side of the vehicle toward the front side of the vehicle corresponding to the height of the side walls 71a and 71b. Further, an extending portion 72a extending downward is continuously formed at the boundary end portion of the bottom surface 72 with the gap 74, and the lowermost portion of the standing wall 73 is also formed on the extending portion 72a. It is formed up to substantially the same position as the lowest part. The rain channel 7 thus configured is made of reinforced nylon, and the side walls 71a, 71b, the bottom surface 72 and the standing wall 73 are integrally formed by injection molding. When the water drops enter, the water drops first flow into the rain channel 7. When the flow of water droplets in the rain channel 7 is relatively slow, such as when the amount of water droplets in the rain channel 7 is small or the vehicle body is not tilted, the water droplets in the rain channel 7 slowly move toward the gap 74. When the water droplets flow and reach the extending portion 72a, the water droplets flow down from the extending portion 72a into the gutter portion 32. Next, when the flow of water droplets in the rain channel 7 is sufficiently fast, such as when there are a large amount of water droplets in the rain channel 7 or the vehicle body is tilted, the water droplets in the rain channel 7 quickly move toward the standing wall 73. The flow and water droplets are scattered toward the outside in the left-right direction near the boundary with the gap 74 without reaching the lowermost part of the extending part 72a, hitting the standing wall 73 and entering the rain gutter part 32 from the lowest end 73 of the standing wall. Guided reliably. As described above, the water droplets that have fallen into the rain gutter 32 are discharged to the outside through the drain port 33 formed at the end of the vehicle in the front-rear direction.
[0015]
The embodiment of the present invention has been described above, but the present invention is not intended to be limited to the above-described embodiment. For example, the guide rail and the first gutter member are configured separately, Any form of sunroof device may be used as long as the guide rail and the front frame are integrally formed.
[0016]
【The invention's effect】
According to the present invention, when the speed of water droplets flowing through the second gutter member is sufficiently high, the water droplets in the second gutter member do not flow down directly from the end of the second gutter portion into the first gutter portion, Once it hits the standing wall, it flows down into the first gutter. Since the standing wall is formed integrally with the second gutter member, the water droplet is guided into the first gutter portion regardless of the speed of the water droplet in the second gutter member, thereby increasing the number of parts. It is possible to prevent water droplets from being scattered outside.
