Summary of the Invention

Problems to be Solved by the Invention

[0003] However, in the above sunroof device, since it is necessary to provide two drainage grooves, a drainage groove for sunroof panel drainage and a drainage groove for guide rail drainage, in the guide rail, the cross-section of the guide rail becomes complicated and the manufacturing cost increases. In addition, since a space for providing the second drainage groove is required on the sunroof opening side, the area of the sunroof opening becomes small and the commerciality of the sunroof device deteriorates.

[0004] The present invention has been made in view of the above problems, and an object thereof is to provide a sunroof device capable of reducing the size of the guide rail and increasing the area of the sunroof opening.

Means for Solving the Problems

[0005] The sunroof device according to the present invention comprises a pair of guide rails extending in the longitudinal direction of the vehicle and provided on both sides of the sunroof opening in the vehicle width direction, a panel drain member extending in the vehicle width direction and traversing the sunroof opening, and a pair of draining devices attached to the pair of guide rails and each located below the ends of the panel drain member in the vehicle width direction, wherein the panel drain member is provided with a panel drain groove extending in the vehicle width direction, each guide rail is provided with only one guide rail drain groove extending in the longitudinal direction, and the draining devices are configured such that water flowing out of the panel drain groove is introduced into the guide rail drain groove via the draining devices.

[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 introduced 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 a case where the guide rail is provided with two drainage grooves, one for guide rail drainage and one for panel drainage to receive water from the panel drainage member, the cross-sectional structure of the guide rail can be simplified, the dimensions of the guide rail in the vehicle width direction can be reduced, and consequently, the manufacturing cost of the guide rail can be reduced, and the area of ​​the sunroof opening can be increased, thereby improving the marketability of the sunroof device.

[0007] Furthermore, in the present invention, preferably, the guide rail drainage groove is partitioned by a pair of drainage groove walls in the guide rail, and an opening or recess is provided through the drainage groove wall that is closer to the inside in the vehicle width direction of the pair of drainage groove walls, and the drainage device is inserted into the opening or recess.

[0008] According to the above structure, since the draining device is inserted into the opening or groove in the drainage channel wall of the guide rail, there is no need to add vertical space to accommodate the draining device, thus reducing the overall height of the sunroof system.

[0009] Furthermore, in the present invention, preferably, the lower edge of the opening is inclined to be located lower towards the guide rail drainage groove side, and the bottom wall of the draining device has a first portion and a second portion in order from the outside to the inside in the vehicle width direction, and when the draining device is attached to the guide rail, at least the tip of the first portion abuts against the lower edge of the opening and is inclined to be located lower towards the guide rail drainage groove side.

[0010] According to the above structure, the first portion of the bottom wall of the draining device is inclined so as to be positioned lower towards the guide rail drainage groove, and is inserted into an opening whose lower edge is similarly inclined. This allows water flowing out from the panel draining member to be guided smoothly into the guide rail drainage groove, and also increases the water flow velocity, thereby increasing the drainage volume.

[0011] Furthermore, in the present invention, preferably, the second portion of the bottom wall is formed to be inclined such that, when the draining device is attached to the guide rail, it is located lower towards the guide rail drainage groove side.

[0012] According to the above structure, water flowing out from the panel drainage member can be smoothly guided into the guide rail drainage groove, preventing it from remaining inside the drainage device.

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

[0014] According to the above structure, the second part further increases the water flow velocity, allowing the water to be smoothly discharged through the guide rail drainage groove.

[0015] Furthermore, in the present invention, preferably, a notch is formed in the wall portion of the guide rail that is located inward in the vehicle width direction from the pair of drainage channel wall portions, into which the drainage device is fitted.

[0016] According to the above structure, since a notch is formed into which the drainage device is fitted, there is no need to place a space above the guide rail to accommodate the drainage device, and thus the overall height of the sunroof device can be reduced.

[0017] Furthermore, in the present invention, preferably, the draining device has a pair of side walls on both sides in the front-rear 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 projection, and when the draining device is attached to the guide rail, the pair of side walls abut against the drainage channel wall portion provided with the opening or groove from the inside in the vehicle width direction, and the projection engages with the wall portion of the guide rail where the notch is formed from the outside in the vehicle width direction, thereby fixing the draining device to the guide rail.

[0018] According to the above structure, the movement of the draining device in the vehicle width direction is restricted by the drainage channel wall and the guide rail wall, thereby allowing the draining device to be stably fixed to the guide rail of the sunroof device. Moreover, the simple locking structure makes it easy to install the draining device. Furthermore, the draining device is provided with a pair of side walls, which prevents water flowing into the draining device from entering the vehicle interior from both the front and rear sides.

[0019] Furthermore, in the present invention, preferably, the draining device has a base end side wall that rises upward from the second portion of the bottom wall on the inside in the vehicle width direction of the second portion and extends in the front-rear direction, and the base end side wall is located on the inside in the vehicle width direction relative to both ends of the panel draining member in the vehicle width direction when the draining device is attached to the guide rail.

[0020] According to the above structure, the draining device is installed in a drawer shape having a base side wall and two side walls, which makes it possible to more reliably prevent water flowing into the draining device from entering the vehicle interior.

[0021] In addition, in the present invention, preferably, the sunroof device has a sunroof panel that shields the sunroof opening and includes a front panel and a rear panel arranged side by side in the front-rear direction, and at least one of the front panel and the rear panel is guided by the pair of guide rails and is slidable, and the panel drain member is located between the front panel and the rear panel.

[0022] In addition, in the present invention, preferably, the guide rail drain groove also serves as a sliding groove in which at least one slider 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 made simpler, the dimension in the width direction of the guide rail can be reduced, and the area of the sunroof opening can be increased.

[Figure 3] It is a schematic diagram for explaining the situation where the drain is attached to the guide rail. [Figure 4] It is a cross-sectional view taken along line B-B in FIG. 2.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the direction along the front and rear of the vehicle is referred to as the front-rear direction X, the direction along the width of the vehicle is referred to as the vehicle width direction Y, and the direction along the up and down of the vehicle is referred to as the up-down direction Z.

[0026] Figure 1 is a schematic diagram showing a sunroof device according to the present invention. Figure 2 shows the structure near the drainage device of the sunroof device in part A of Figure 1. Figure 3 is a schematic diagram illustrating how the drainage device is attached to the guide rail. Figure 4 is a cross-sectional view along line BB of Figure 2. In Figures 2 to 4, for the sake of clarity, 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 omitted from the illustration.

[0027] The sunroof device 1 is mounted on the roof of the vehicle, and as shown in Figure 1, the sunroof device 1 has a front panel 2, a rear panel 3, a pair of guide rails 4, a panel drain member 5, a pair of drainers 6 (see Figure 2), a front frame 8, and a rear frame 9. Here, the area enclosed 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 plan view. At least one of the front panel 2 and the rear panel 3 may be light-transmitting, for example, it may transmit all light, selectively transmit a portion of the light, or even have the function of blocking ultraviolet rays. The front panel 2 and the rear panel 3 can be made of any known panel material, for example, glass.

[0029] Furthermore, the front panel 2 and the rear panel 3 are each slidable in the longitudinal direction X of the vehicle in conjunction with the operation of their connected sliders (not shown). However, the design is not limited to this; one of the front panel 2 and the rear panel 3 may be movable in the longitudinal direction X of the vehicle in conjunction with the operation of its slider, while the other is 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 Figures 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 to this; the material of the guide rails is not particularly limited as long as it can perform the functions required of the guide rails. The pair of guide rails 4 extend in the longitudinal 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 longitudinal direction X. Specifically, each of the pair of guide rails 4 is provided with a sliding groove 43, and the slider of at least one of the front panel 2 and the rear panel 3 slides in the sliding groove 43, and furthermore, at least one of the front panel 2 and the rear panel 3 is guided to move in the longitudinal direction X. In addition, each guide rail 4 is provided with only one guide rail drainage groove 41 that extends in the longitudinal direction X, and the guide rail drainage groove 41 discharges water that enters the vehicle interior from the sunroof device 1 to the outside of the vehicle. The guide rail drainage groove 41 is defined by a pair of drainage groove walls 41a and 41b in the guide rail 4. In this embodiment, the guide rail drainage groove 41 also serves as a sliding groove 43 on which the sliders of the front panel 2 and rear panel 3 slide. However, in other embodiments, the guide rail drainage groove and the sliding groove may be provided separately.

[0031] Furthermore, as shown in Figures 3 and 4, an opening 42 for inserting a draining device 6 is provided through the draining wall portion 41a, which is closer to the inside in the vehicle width direction Y of the pair of draining wall portions 41a and 41b. The opening 42 may be formed by cutting it at an angle to the draining wall portion 41a, for example. The lower edge 42a of the opening 42 is inclined to be located lower towards the guide rail draining groove 41 side. Here, the lower edge 42a of the opening 42 does not strictly refer to the lower edge of the opening in the draining wall portion 41a, but further includes a portion formed near the draining wall portion 41a by the same cutting process, etc., and connected to the lower edge of the draining wall portion 41a and on the same inclined surface.

[0032] Furthermore, in the guide rail 4, a notch 45 is formed in the wall portion 44 located inward in the vehicle width direction Y from the pair of drainage channel wall portions 41a and 41b, into which the drainage device 6 is fitted.

[0033] As shown in Figures 1 and 2, the panel drain 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 drain member 5 is a component for draining water from between the front panel 2 and the rear panel 3 to the guide rail 4. The panel drain member 5 is provided with a panel drain 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 drain member 5 from above and then flows outward along the panel drain member 5 in the vehicle width direction Y.

[0034] As shown in Figures 2 and 4, each pair of drainers 6 is attached to each pair of guide rails 4. Each pair of drainers 6 is located below both ends of the panel drain member 5 in the vehicle width direction Y. In the longitudinal direction X of the vehicle, the pair of drainers 6 are located at approximately the same position as both ends of the panel drain member 5 in the vehicle width direction Y. The drainers 6 are configured so that water flowing out of the panel drain groove 51 of the panel drain member 5 is introduced into the guide rail drain groove 41 of the guide rail 4 via the drainers 6, as shown by the arrows in Figures 2 and 4.

[0035] As shown in Figures 3 and 4, the draining device 6 has a drawer-like shape and includes a bottom wall 61 that slopes downward toward the guide rail drain groove 41 when the draining 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 draining device 6 in the front-rear direction X, and a base end side wall 63 that rises upward from the bottom wall 61 and extends in the front-rear direction X on the inside of the bottom wall 61 in the vehicle width direction Y.

[0036] The bottom wall 61 of the draining device 6 has a first portion 611 and a second portion 612, in order from the outside to the inside in the vehicle width direction Y. When the draining device 6 is attached to the guide rail 4, the tip of the first portion 611 abuts against the lower edge 42a of the opening 42 and is inclined to be located lower towards the guide rail drain groove 41, and the second portion 612 is also inclined to be located lower towards the guide rail drain groove 41. The angle of inclination of the first portion 611 with respect to the horizontal is greater than the angle of inclination of the second portion 612 with respect to the horizontal.

[0037] Each of the pair of side walls 62 is provided with a projection 64 near the base side wall 63, which engages with the wall portion 44 of the guide rail 4 to secure the draining device 6 to the guide rail 4. However, the position of the projection 64 is not limited to the above position on the side wall 62; the projection 64 may be provided at any suitable position on the side wall 62 as long as the draining device 6 can be stably fixed to the guide rail 4.

[0038] The base 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 draining device 6 is attached to the guide rail 4, the base side wall 63 is located inward in the vehicle width direction Y than both ends of the panel draining member 5 in the vehicle width direction Y.

[0039] Next, the installation 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. Then, 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, and the pair of side walls 62 come into contact with the drainage channel wall portion 41a from the inside in the vehicle width direction Y. The projection 64 provided on the side wall 62 of 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 Figure 3 until it is locked into the wall portion 44 of the guide rail 4 from the outside in the vehicle width direction Y. The opposite side of the base end side wall 63 of the draining device 6 is inserted into the opening 42 in the drainage channel wall portion 41a of the guide rail 4. This completes the installation of the draining device 6 to the guide rail 4.

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

[0041] According to the structure of the sunroof device of the present invention described above, the guide rail 4 is provided with only one guide rail drainage groove 41, and water flowing out from the panel drainage groove 51 of the panel drainage member 5 via a separately provided drainage device 6 is introduced into the guide rail drainage groove 41, thereby achieving drainage of both the guide rail and the sunroof panel. Compared to the case where the guide rail is provided with two drainage grooves, one for guide rail drainage and one for panel drainage to receive water from the panel drainage member, the cross-sectional structure of the guide rail can be simplified and the dimensions of the guide rail in the vehicle width direction can be reduced, which in turn can reduce the manufacturing cost of the guide rail and increase the area of ​​the sunroof opening, thereby improving the marketability of the sunroof device.

[0042] Furthermore, in this embodiment, an opening 42 through which the drainage device 6 is inserted is provided in the drainage channel wall portion 41a on the inner side in the vehicle width direction Y. Therefore, there is no need to add space in the vertical direction Z to accommodate the drainage device 6, and thus the overall height of the sunroof device 1 is reduced.

[0043] Furthermore, in this embodiment, the lower edge 42a of the opening 42 is inclined to be located lower towards the guide rail drainage groove 41, and when the draining device 6 is attached to the guide rail 4, the first portion 611 of the bottom wall 61 of the draining device 6 that abuts against the lower edge 42a of the opening 42 is also inclined to be located lower towards the guide rail drainage groove 41.

[0044] This allows the water flowing out from the panel drain member 5 to be guided smoothly into the guide rail drain groove 41, and also increases the water flow velocity, thereby increasing the amount of water drained.

[0045] Furthermore, in this embodiment, the second portion 612 of the bottom wall 61 is formed to be inclined so that it is located lower towards the guide rail drainage groove 41 when the draining device 6 is attached to the guide rail 4. This further guides the water flowing out from the panel draining member 5 to flow smoothly into the guide rail drainage groove 41 and prevent it from remaining inside the draining device 6.

[0046] Furthermore, in this embodiment, the inclination angle of the first portion 611 with respect to the horizontal is greater than the inclination angle of the second portion 612 with respect to the horizontal. This allows the second portion 612 to further increase the water flow velocity, enabling smoother discharge of water into the guide rail drainage channel 41.

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

[0048] Furthermore, in this embodiment, the draining device 6 has a pair of side walls 62 on both sides in the front-rear 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 projection 64 that engages with the wall portion 44 of the guide rail 4.

[0049] As a result, the movement of the draining device 6 in the vehicle width direction Y is restricted by the drainage channel wall 41a and the guide rail 4 wall 44, thereby allowing the draining device 6 to be stably fixed to the guide rail 4 of the sunroof device 1. Moreover, the simple locking structure makes it easy to install the draining device 6. Furthermore, the draining device 6 is provided with a pair of side walls 62, which prevents water flowing into the draining device 6 from entering the vehicle interior from both sides in the front-rear direction X.

[0050] Furthermore, in this embodiment, the drainer 6 has a base end side wall 63 that rises upward from the second portion 612 of the bottom wall 612 and extends in the front-rear direction X, on the inside of the second portion 612 in the vehicle width direction Y, and when the drainer 6 is attached to the guide rail 4, the base end side wall 63 is located on the inside of the vehicle width direction Y relative to both ends of the panel drain member 5 in the vehicle width direction Y. As a result, the drainer 6 is installed in a drawer shape having a base end side wall 63 and two side walls 62, which makes it possible to more reliably prevent water flowing into the drainer 6 from entering the vehicle interior.

[0051] Furthermore, in this embodiment, the guide rail drainage groove 41 also serves as a sliding groove 43 through which at least one of the sliders 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 widthwise dimension of the guide rail 4, and increases the area of ​​the sunroof opening.

[0052] Preferred embodiments of the present invention have been described above, but the invention is not limited thereto. Various modifications can be made as follows.

[0053] In the above preferred embodiment, the draining device 6 is inserted into the opening 42 of the drainage channel wall portion 41a and fitted into the notch 45 in the wall portion 44 of the guide rail 4. However, the draining device 6 may be mounted in any other way as long as it can introduce water from the panel draining member 5 into the guide rail drainage channel 41 of the guide rail 4. For example, the draining device may be straddled over the guide rail 4. In this case, it is not necessary to provide openings 42 or notches 45 in each wall portion of the guide rail.

[0054] In the above preferred embodiment, the drain wall portion 41a is provided with an opening 42 through which the draining device 6 is inserted, but it is not limited to this. The drain wall portion 41a may also be provided with a recessed groove that opens upwards through which the draining device 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 above preferred embodiment, the entire bottom wall 61 of the draining device 6 is formed to be inclined so that it is located lower toward the guide rail drain groove 41 when the draining device 6 is attached to the guide rail 4. However, the installation of the bottom wall 61 of the draining device 6 is not limited to the above 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 to be inclined so that it is located lower toward the guide rail drain groove 41. In the above preferred embodiment, the inclination angle of the first portion 611 is greater than the inclination angle of the second portion 612, but this is not limited to this. For example, the inclination angle of the first portion 611 may be the same as the inclination angle of the second portion 612, or it may be 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 to this, and the inclination angles of the two are not particularly limited as long as the first portion 611 can abut against the lower edge 42a.

[0056] In the above preferred embodiment, the tip of the first portion 611 abuts against the lower edge 42a of the opening 42, but the first portion 611 may extend further through the guide rail drainage groove 41, as long as it does not obstruct the drainage of the guide rail drainage groove 41.

[0057] In the above preferred embodiment, the drainer 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. However, the shape of the drainer 6 is not particularly limited as long as it can prevent water flowing from the panel drain member 5 into the drainer 6 and into the passenger compartment. 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 passenger compartment.

[0058] Furthermore, in the above preferred embodiment, the draining device 6 is fixed to the guide rail 4 by a projection 64 provided on the side wall 62 of the draining device 6 engaging with the wall portion 44 in the guide rail 4 where the notch 45 is formed. However, the method of fixing the draining device 6 to the guide rail is not limited to this, and for example, screw holes may be provided in both the guide rail and the draining device, and the two may be fixed together via screw members such as screws.

[0059] Furthermore, in the above preferred embodiment, the panel drain member 5 was described in a situation where it is located between the front panel 2 and the rear panel 3. However, it is not limited to this, and the panel drain 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. If there is only one sunroof panel, it may be located between the sunroof panel and the front frame or the rear frame.

[0060] Embodiments of the present invention have been described above. However, the present invention is not limited to the embodiments described above. Embodiments obtained by persons skilled in the art by making appropriate changes, combinations, or deletions to the above components are also included within the scope of the claims of the present invention, without departing from the spirit of the invention.
