Description

[Technical Field]

[0001] The present invention relates to a sunroof device, and more particularly to a drainage structure for a sunroof device. [Background technology]

[0002] A conventional sunroof device for a vehicle includes a pair of guide rails extending in the front-to-rear direction of the vehicle and provided on both sides of the sunroof opening in the vehicle width direction, and a panel drainage member extending in the vehicle width direction and crossing the sunroof opening. The panel drainage member is provided with a panel drainage groove extending in the vehicle width direction, and each guide rail is provided with a first drainage groove and a second drainage groove extending in the front-to-rear direction and arranged side by side in the vehicle width direction. The first drainage groove is used to drain water on the guide rail to the outside of the vehicle. The second drainage groove is located below both ends of the panel drainage member in the vehicle width direction, and water flows directly from the panel drainage groove into the second drainage groove and is guided by the second drainage groove to be discharged to the outside of the vehicle. Summary of the Invention [Problem to be solved by the invention]

[0003] However, in the above sunroof device, the guide rail must be provided with two drainage grooves, one for the sunroof panel and one for the guide rail, which makes the cross section of the guide rail complex and increases manufacturing costs. Also, since space is required on the sunroof opening side to provide the second drainage groove, the area of the sunroof opening becomes smaller, which reduces the marketability of the sunroof device.

[0004] The present invention has been made in view of the above-mentioned problems, and has an object to provide a sunroof device that can increase the area of the sunroof opening while reducing the size of the guide rails. [Means for solving the problem]

[0005] The sunroof device of the present invention comprises a pair of guide rails extending in the fore-and-aft direction of the vehicle and provided on both sides of the sunroof opening in the vehicle width direction, a panel drainage member extending in the vehicle width direction and crossing the sunroof opening, and a pair of drainage tools attached to the pair of guide rails and positioned lower than both end portions of the panel drainage member in the vehicle width direction, wherein the panel drainage member has a panel drainage groove extending in the vehicle width direction, and each guide rail has only one guide rail drainage groove extending in the fore-and-aft direction, and the drainage tool is configured so that water flowing out from the panel drainage groove is guided into the guide rail drainage groove via the drainage tool.

[0006] According to the above structure, the guide rail is provided with only one guide rail drainage groove, and water flowing out from the panel drainage groove of the panel drainage member is guided into the guide rail drainage groove via a separately provided drainage device, thereby achieving drainage of both the guide rail and the sunroof panel. Compared to when the guide rail is provided with two drainage grooves, one for guide rail drainage and one for panel drainage for receiving water from the panel drainage member, the cross-sectional structure of the guide rail can be simplified and the dimension of the guide rail in the vehicle width direction can be reduced, which in turn reduces the manufacturing cost of the guide rail and increases the area of the sunroof opening, improving the marketability of the sunroof device.

[0007] In addition, in the present invention, preferably, the guide rail drain groove is defined and formed by a pair of drain groove wall portions on the guide rail, and an opening or groove is provided so as to pass through the drain groove wall portion of the pair that is closer to the inside in the vehicle width direction, and the drain device is inserted into the opening or groove.

[0008] According to the above structure, the drainage device is inserted into an opening or recessed groove in the drainage groove wall portion of the guide rail, so there is no need to add vertical space to accommodate the drainage device, thereby reducing the height of the entire sunroof device.

[0009] In addition, in the present invention, preferably, the lower edge of the opening is inclined so that it is positioned downward as it approaches the guide rail drain groove, and the bottom wall of the drain device has a first part and a second part, in that order, from the outside to the inside in the vehicle width direction, and when the drain device is attached to the guide rail, at least the tip of the first part abuts the lower edge of the opening and is inclined so that it is positioned downward as it approaches the guide rail drain groove.

[0010] According to the above structure, the first part of the bottom wall of the drainage device is inclined downward toward the guide rail drainage groove, and is inserted into an opening whose lower edge is inclined in the same way. This allows water flowing out of the panel drainage member to be guided smoothly into the guide rail drainage groove, and also increases the water flow speed and the amount of water discharged.

[0011] Also, in the present invention, preferably, the second portion of the bottom wall is formed so as to be inclined downwards toward the guide rail drain groove when the draining tool is attached to the guide rail.

[0012] According to the above structure, water flowing out from the panel drainage member flows smoothly into the guide rail drainage groove, and can be further guided so as not to remain inside the drainage device.

[0013] In the present invention, preferably, the angle of inclination of the first portion with respect to the horizontal direction is larger than the angle of inclination of the second portion with respect to the horizontal direction.

[0014] According to the above structure, the second portion further increases the water flow velocity, allowing the water to be discharged more smoothly into the guide rail drain groove.

[0015] In the present invention, preferably, a wall portion of the guide rail located more inward in the vehicle width direction than the pair of drain groove wall portions is formed with a notch portion into which the drain tool is fitted.

[0016] According to the above structure, a cutout portion into which the drainage device is fitted is formed, so there is no need to arrange space above the guide rail to accommodate the drainage device, thereby reducing the height of the entire sunroof device.

[0017] In addition, in the present invention, it is preferable that the drainage device has a pair of side walls on both sides in the fore-and-aft direction that rise upward from the bottom wall and extend in the vehicle width direction, and each of the pair of side walls is provided with a protrusion, and when the drainage device is attached to the guide rail, the pair of side walls abut against the drainage groove wall portion in which the opening or groove is provided from the inside in the vehicle width direction, and the protrusions engage with the wall portion in which the notch is formed in the guide rail from the outside in the vehicle width direction, thereby fixing the drainage device to the guide rail.

[0018] According to the above structure, the movement of the drainage tool in the vehicle width direction is restricted by the drain groove wall portion and the guide rail wall portion, so that the drainage tool can be stably fixed to the guide rail of the sunroof device. Moreover, the simple structure of the locking makes it easy to install the drainage tool. In addition, the drainage tool is provided with a pair of side walls, so that water that has flowed into the drainage tool can be prevented from entering the vehicle interior from both the front and rear directions.

[0019] In addition, in the present invention, it is preferable that the drainage device has a base end side wall that rises upward from the second part of the bottom wall and extends in the fore-and-aft direction on the inside of the vehicle width direction of the second part, and the base end side wall is positioned on the inside of the vehicle width direction relative to both end parts of the panel drainage member in the vehicle width direction when the drainage device is attached to the guide rail.

[0020] According to the above structure, the drainage device is installed in a drawer shape having a base end side wall and two side walls, which more reliably prevents water that flows into the drainage device from entering the vehicle interior.

[0021] In addition, in the present invention, it is preferable that the sunroof device has a sunroof panel that covers the sunroof opening and includes a front panel and a rear panel arranged side by side in the fore-and-aft direction, at least one of the front panel and the rear panel being slidable while being guided by the pair of guide rails, and the panel drainage member being positioned between the front panel and the rear panel.

[0022] In the present invention, it is also preferable that the guide rail drain groove also serves as a slide groove along which a slider of at least one of the front panel and the rear panel slides.

[0023] According to the above structure, the cross-sectional shape of the guide rail can be further simplified, the dimension of the guide rail in the width direction can be reduced, and the area of the sunroof opening can be increased. [Brief explanation of the drawings]

[Figure 3] FIG. 10 is a schematic diagram for explaining a state in which the drainage tool is attached to the guide rail. [Figure 4] FIG. 3 is a cross-sectional view taken along line BB in FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

[0025] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings. In the following description, the direction along the front and rear of the vehicle will be referred to as the longitudinal direction X, the direction along the width of the vehicle will be referred to as the transverse direction Y, and the direction along the top and bottom of the vehicle will be referred to as the vertical direction Z.

[0026] Fig. 1 is a schematic diagram showing a sunroof device according to the present invention. Fig. 2 shows the structure of the sunroof device in the vicinity of the drainage device in part A in Fig. 1. Fig. 3 is a schematic diagram for explaining how the drainage device is attached to the guide rail. Fig. 4 is a cross-sectional view taken along line BB in Fig. 2. In Figs. 2 to 4, for the sake of simplicity, only the structure of one side of the sunroof device in the vehicle width direction Y is shown, and the structure of the other side is similar and therefore not shown.

[0027] The sunroof device 1 is attached to the roof of a vehicle, and as shown in Fig. 1, the sunroof device 1 has a front panel 2, a rear panel 3, a pair of guide rails 4, a panel drainage member 5, a pair of drainage devices 6 (see Fig. 2), a front frame 8, and a rear frame 9. Here, the area surrounded by the pair of guide rails 4, the front frame 8, and the rear frame 9 connected to each other is the sunroof opening 7 of the sunroof device 1.

[0028] The front panel 2 and the rear panel 3 shield the sunroof opening 7 of the sunroof device 1 and are arranged side by side in the front-to-rear direction X. The front panel 2 and the rear panel 3 each have, for example, a substantially rectangular shape in a plan view. At least one of the front panel 2 and the rear panel 3 may be translucent, for example, it may transmit all light or may selectively transmit part of light, or it may also have a function of blocking ultraviolet light. The front panel 2 and the rear panel 3 may be made of any known panel material, for example, glass.

[0029] Furthermore, the front panel 2 and the rear panel 3 are slidable in the longitudinal direction X of the vehicle in accordance with the movement of sliders (not shown) connected thereto. However, without being limited thereto, one of the front panel 2 and the rear panel 3 may be movable in the longitudinal direction X of the vehicle in accordance with the movement of its slider, while the other may be a fixed panel that cannot move. Alternatively, one of the front panel 2 and the rear panel 3 may slide in the longitudinal direction X of the vehicle in conjunction with the other.

[0030] As shown in FIGS. 2 to 4 , the pair of guide rails 4 may be made of metal, such as aluminum or an aluminum alloy, but are not limited thereto. The material of the guide rails is not particularly limited as long as the required functions of the guide rails can be achieved. The pair of guide rails 4 extend in the front-to-rear direction X of the vehicle and are provided on both sides of the sunroof opening 7 in the vehicle width direction Y. The pair of guide rails 4 guide at least one of the front panel 2 and the rear panel 3 to move in the front-to-rear direction X. Specifically, each of the pair of guide rails 4 is provided with a slide groove 43, and a slider of at least one of the front panel 2 and the rear panel 3 slides in the slide groove 43, thereby guiding at least one of the front panel 2 and the rear panel 3 to move in the front-to-rear direction X. Each guide rail 4 is provided with only one guide rail drain groove 41 extending in the front-to-rear direction X, and the guide rail drain groove 41 drains water that enters the interior of the vehicle through the sunroof device 1 to the outside of the vehicle. The guide rail drain groove 41 is defined by a pair of drain groove walls 41a, 41b in the guide rail 4. In this embodiment, the guide rail drain groove 41 also serves as a slide groove 43 along which the sliders of the front panel 2 and the rear panel 3 slide. However, in other embodiments, the guide rail drain groove and the slide groove may be provided separately.

[0031] 3 and 4, an opening 42 for inserting the drain tool 6 is provided through the drain groove wall 41a of the pair of drain groove walls 41a, 41b that is closer to the inside in the vehicle width direction Y. The opening 42 may be formed, for example, by cutting diagonally relative to the drain groove wall 41a. The lower edge 42a of the opening 42 is inclined so as to be positioned lower as it approaches the guide rail drain groove 41. Here, the lower edge 42a of the opening 42 does not strictly refer to the lower edge of the opening in the drain groove wall 41a, but also includes a portion that is formed near the drain groove wall 41a by the same cutting process or the like, is connected to the lower edge of the drain groove wall 41a, and is on the same inclined plane.

[0032] In addition, in the guide rail 4, a wall portion 44 located more inward in the vehicle width direction Y than the pair of drain groove wall portions 41a, 41b is formed with a notch 45 into which the drain tool 6 is fitted.

[0033] As shown in Figures 1 and 2, the panel drainage member 5 is located between the front panel 2 and the rear panel 3, extends along the vehicle width direction Y, and crosses the sunroof opening 7. The panel drainage member 5 is a member for discharging water from between the front panel 2 and the rear panel 3 into the guide rail 4. The panel drainage member 5 is provided with a panel drainage groove 51 that extends in the vehicle width direction Y. As shown by the arrows in Figures 1 and 2, water flows into the panel drainage member 5 from above and then flows along the panel drainage member 5 to the outside in the vehicle width direction Y.

[0034] As shown in Figures 2 and 4, a pair of drainage devices 6 are attached to a pair of guide rails 4, respectively. The pair of drainage devices 6 are located lower than both ends of the panel drainage member 5 in the vehicle width direction Y. In the front-rear direction X of the vehicle, the pair of drainage devices 6 are located at approximately the same positions as both ends of the panel drainage member 5 in the vehicle width direction Y. The drainage devices 6 are configured so that water flowing out from the panel drainage grooves 51 of the panel drainage member 5 is introduced into the guide rail drainage grooves 41 of the guide rails 4 via the drainage devices 6, as shown by the arrows in Figures 2 and 4.

[0035] As shown in Figures 3 and 4, the drainage device 6 is drawer-shaped and includes a bottom wall 61 that is inclined so that it is positioned downward toward the guide rail drainage groove 41 when the drainage device 6 is attached to the guide rail 4, a pair of side walls 62 that rise upward from the bottom wall 61 and extend in the vehicle width direction Y on both sides of the drainage device 6 in the fore-and-aft direction X, and a base side wall 63 that rises upward from the bottom wall 61 and extends in the fore-and-aft direction X on the inside of the bottom wall 61 in the vehicle width direction Y.

[0036] The bottom wall 61 of the drainage device 6 has a first portion 611 and a second portion 612, arranged in this order from the outside to the inside in the vehicle width direction Y. When the drainage device 6 is attached to the guide rail 4, the tip of the first portion 611 abuts the lower edge 42a of the opening 42 and is inclined so as to be positioned downward toward the guide rail drainage groove 41, while the second portion 612 is inclined so as to be positioned downward toward the guide rail drainage groove 41. The angle of inclination of the first portion 611 with respect to the horizontal direction is greater than the angle of inclination of the second portion 612 with respect to the horizontal direction.

[0037] A protrusion 64 is provided at a position near the base end side wall 63 of each of the pair of side walls 62, and engages with the wall portion 44 of the guide rail 4 so as to fix the drainage tool 6 to the guide rail 4. However, the installation position of the protrusion 64 is not limited to the above position on the side wall 62, and the protrusion 64 may be provided at any appropriate position on the side wall 62 as long as the drainage tool 6 can be stably fixed to the guide rail 4.

[0038] The base end side wall 63 rises upward from the second portion 612 of the bottom wall 61 and extends in the front-rear direction X. When the drainage tool 6 is attached to the guide rail 4, the base end side wall 63 is located more inward in the vehicle width direction Y than both end portions of the panel drainage member 5 in the vehicle width direction Y.

[0039] Next, the attachment of the draining device 6 to the guide rail 4 will be described. The draining device 6 is fitted into the notch 45 of the wall portion 44 of the guide rail 4 from the inside in the vehicle width direction Y, and then the draining device 6 is guided by the notch 45 and moved outward in the vehicle width direction Y as shown by the arrow in FIG. 3 until the first portion 611 of the bottom wall 61 of the draining device 6 is supported by the lower edge 42a of the opening 42, the pair of side walls 62 abut against the drain groove wall portion 41a from the inside in the vehicle width direction Y, and the protrusions 64 provided on the side walls 62 of the draining device 6 are engaged with the wall portion 44 of the guide rail 4 from the outside in the vehicle width direction Y through the notch 45, and the opposite side of the base end side wall 63 of the draining device 6 is inserted into the opening 42 in the drain groove wall portion 41a of the guide rail 4. This completes the attachment of the draining device 6 to the guide rail 4.

[0040] The effects of this embodiment will be described below.

[0041] According to the sunroof device structure of the present invention, only one guide rail drainage groove 41 is provided in the guide rail 4, and water that flows out from the panel drainage groove 51 of the panel drainage member 5 is introduced into the guide rail drainage groove 41 via a separately provided drainage device 6, thereby achieving drainage of both the guide rail and the sunroof panel. Compared to when the guide rail is provided with two drainage grooves, one for guide rail drainage and one for panel drainage for receiving water from the panel drainage member, the cross-sectional structure of the guide rail can be simplified and the dimension of the guide rail in the vehicle width direction can be reduced, which in turn reduces the manufacturing cost of the guide rail and increases the area of the sunroof opening, improving the marketability of the sunroof device.

[0042] In this embodiment, an opening 42 through which the drain tool 6 is inserted is provided so as to penetrate the drain groove wall portion 41a located closer to the inside in the vehicle width direction Y. Therefore, there is no need to add space in the vertical direction Z to accommodate the drain tool 6, and the height of the entire sunroof device 1 is reduced.

[0043] In addition, in this embodiment, the lower edge 42a of the opening 42 is inclined so that it is positioned downward toward the guide rail drain groove 41, and when the drain device 6 is attached to the guide rail 4, the first part 611 that abuts against the lower edge 42a of the opening 42 on the bottom wall 61 of the drain device 6 is also inclined so that it is positioned downward toward the guide rail drain groove 41.

[0044] This allows the water flowing out from the panel drainage member 5 to be guided so that it flows smoothly into the guide rail drainage groove 41, and also increases the water flow speed and the amount of drainage.

[0045] In this embodiment, the second portion 612 of the bottom wall 61 is formed to be inclined so that it is positioned downward toward the guide rail drain groove 41 when the drain device 6 is attached to the guide rail 4. This allows water that flows out from the panel drain member 5 to smoothly flow into the guide rail drain groove 41, and further guides it so that it does not remain inside the drain device 6.

[0046] In this embodiment, the angle of inclination of the first portion 611 relative to the horizontal direction is greater than the angle of inclination of the second portion 612 relative to the horizontal direction. This allows the second portion 612 to further increase the water flow speed, allowing water to be discharged into the guide rail drain groove 41 more smoothly.

[0047] In this embodiment, a notch 45 into which the drainage tool 6 is fitted is formed in the wall portion 44 of the guide rail 4. Therefore, there is no need to provide a space above the guide rail 4 to accommodate the drainage tool 6, and the overall height of the sunroof device 1 can be reduced.

[0048] In addition, in this embodiment, the drainage device 6 has a pair of side walls 62 on both sides in the fore-and-aft direction X that rise upward from the bottom wall 61 and extend in the vehicle width direction Y, and each of the pair of side walls 62 is provided with a protrusion 64 that engages with the wall portion 44 of the guide rail 4.

[0049] As a result, movement of the drainage device 6 in the vehicle width direction Y is limited by the drain groove wall portion 41a and the wall portion 44 of the guide rail 4, so that the drainage device 6 can be stably fixed to the guide rail 4 of the sunroof device 1. Moreover, the simple structure of locking makes it easy to attach the drainage device 6. Furthermore, the drainage device 6 is provided with a pair of side walls 62, which prevents water that has flowed into the drainage device 6 from entering the vehicle interior from both sides in the front-rear direction X.

[0050] In addition, in this embodiment, the drainage device 6 has a base end side wall 63 that rises upward from the second portion 612 of the bottom wall 61 on the inside in the vehicle width direction Y of the second portion 612 and extends in the front-to-rear direction X, and when the drainage device 6 is attached to the guide rail 4, the base end side wall 63 is located on the inside in the vehicle width direction Y of both end portions in the vehicle width direction Y of the panel drainage member 5. As a result, the drainage device 6 is installed in a drawer shape having the base end side wall 63 and the two side walls 62, which more reliably prevents water that has flowed into the drainage device 6 from entering the vehicle compartment.

[0051] In this embodiment, the guide rail drain groove 41 also serves as a slide groove 43 along which a slider of at least one of the front panel 2 and the rear panel 3 slides. This further simplifies the cross-sectional shape of the guide rail 4, reduces the width dimension of the guide rail 4, and increases the area of the sunroof opening.

[0052] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this and various modifications can be made as follows.

[0053] In the above-described preferred embodiment, the drain device 6 is inserted into the opening 42 in the drain groove wall portion 41a and fitted into the notch 45 in the wall portion 44 of the guide rail 4. However, the drain device 6 may be attached in a different manner as long as it can guide the water from the panel drain member 5 into the guide rail drain groove 41 of the guide rail 4, for example, the drain device may be mounted across the guide rail 4. In this case, there is no need to provide the opening 42 or the notch 45 in each wall portion of the guide rail.

[0054] In the above-described preferred embodiment, the drain groove wall portion 41a is provided with the opening 42 through which the drain tool 6 is inserted, but is not limited to this. The drain groove wall portion 41a may be provided with a recessed groove that opens upward and through which the drain tool 6 is inserted, as long as it does not affect the movement of the sunroof panel guided by the guide rail 4.

[0055] In the preferred embodiment, the entire bottom wall 61 of the drainer 6 is inclined so that it is positioned downward toward the guide rail drain groove 41 when the drainer 6 is attached to the guide rail 4. However, the installation of the bottom wall 61 of the drainer 6 is not limited to the above-described method. For example, the entire bottom wall 61 may be installed horizontally, or one of the first portion 611 and the second portion 612 of the bottom wall 61 may be installed horizontally, and the other may be installed so that it is inclined so that it is positioned downward toward the guide rail drain groove 41. Note that, although the inclination angle of the first portion 611 is larger than the inclination angle of the second portion 612 in the preferred embodiment, this is not limiting. For example, the inclination angle of the first portion 611 may be the same as or smaller than the inclination angle of the second portion 612. Furthermore, it is preferable that the inclination angle of the first portion 611 is the same as the inclination angle of the lower edge 42a. However, this is not limited thereto, and the inclination angles of the first portion 611 and the second portion 612 are not particularly limited as long as the first portion 611 can abut against the lower edge 42a.

[0056] Here, in the above preferred embodiment, the tip of the first portion 611 abuts the lower edge 42a of the opening 42, but the first portion 611 may penetrate further through the guide rail drainage groove 41 as long as it does not interfere with drainage of the guide rail drainage groove 41.

[0057] In the above-described preferred embodiment, the drain tool 6 is formed in a drawer shape having a base end side wall 63 rising upward from the bottom wall 61 and a pair of side walls 62, but the shape of the drain tool 6 is not particularly limited as long as it can prevent water that has flowed into the drain tool 6 from the panel drain member 5 from entering the vehicle interior through the drain tool 6. For example, if the inclination angle of the bottom wall 61 is sufficiently large, it is not necessary to provide a base end side wall to prevent water from entering the vehicle interior.

[0058] Furthermore, in the above-described preferred embodiment, the projection 64 provided on the side wall 62 of the drainage tool 6 engages with the wall portion 44 in which the notch 45 of the guide rail 4 is formed, thereby fixing the drainage tool 6 to the guide rail 4. However, the method of fixing the drainage tool 6 to the guide rail is not limited to this, and for example, by providing threaded holes in both the guide rail and the drainage tool, the two may be fixed together via a threaded member such as a screw.

[0059] In the above preferred embodiment, the panel drainage member 5 is described as being located between the front panel 2 and the rear panel 3. However, this is not limiting, and the panel drainage member 5 may be provided between the front panel 2 and the front frame 8, or between the rear panel 3 and the rear frame 9. In cases where there is only one sunroof panel, the panel drainage member 5 may be located between the sunroof panel and the front frame or the rear frame.

[0060] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments. Any modifications, combinations, or deletions of the above components by those skilled in the art that do not deviate from the spirit of the present invention are also included within the scope of the claims of the present invention.
