[0002] A conventional sunroof device of a vehicle includes a pair of guide rails extending along a front-rear direction of the vehicle and each disposed on either side of a sunroof opening in a vehicle width direction; and a panel drainage component extending in the vehicle width direction and traversing the sunroof opening. The panel drainage component is provided with a panel drainage groove extending in the vehicle width direction. Each guide rail is provided with a first drainage groove and a second drainage groove extending in the front-rear direction and disposed adjacent to each other in the vehicle width direction. The first drainage groove serves to drain water on the guide rail out of the vehicle.The second drainage groove is arranged below the two ends of the panel drainage component in the vehicle width direction, and the water flows directly from the panel drainage component into the second drainage groove and is drained out of the vehicle through the guide via the second drainage groove.

[0003] However, the above sunroof device requires two drainage grooves on the guide rail for the sunroof panel drainage and the guide rail drainage, respectively. This results in a complex cross-section of the guide rail and high manufacturing costs. Furthermore, space must be created on the sunroof opening side to install the second drainage groove. Therefore, the sunroof opening area becomes smaller, and the commercial quality of the sunroof device deteriorates. Brief summary of the utility model

[0004] The present invention is completed in view of the above-mentioned problems, and an object of the present invention is to provide a sunroof device which can downsize the guide rail and increase the area of ​​the sunroof opening.

[0005] The present invention relates to a sunroof device including a pair of guide rails extending along a front-rear direction of a vehicle and respectively disposed on both sides of a sunroof opening in a vehicle width direction; a panel drainage component extending in the vehicle width direction and traversing the sunroof opening; and a pair of drainage members respectively attached to the pair of guide rails and respectively disposed below two end portions of the panel drainage component in the vehicle width direction. The panel drainage component is provided with a panel drainage groove extending in the vehicle width direction. Each of the guide rails is provided with only one guide rail drainage groove extending in the front-rear direction.The drainage element is configured such that water flowing out of the panel drainage groove is directed via the drainage element into the guide rail drainage groove.

[0006] According to the above structure, only one guide rail drainage groove is provided on the guide rail, and water flowing from the panel drainage groove of the panel drainage component is guided into the above guide rail drainage groove via a separately provided drainage member, thereby simultaneously achieving the drainage of the guide rail and the drainage of the sunroof panel.Compared with a case where two drainage grooves, namely a drainage groove for guide rail drainage and a drainage groove for panel drainage for receiving water from the panel drainage component, are provided on the guide rail, the cross-sectional structure of the guide rail can be simplified, the dimension of the guide rail in the vehicle width direction can be reduced, the manufacturing cost of the guide rail can be reduced, and the area of ​​the sunroof opening can be increased, so that the commercial quality of the sunroof device is improved.

[0007] Moreover, in the present invention, preferably, the guide rail drainage groove is formed by a pair of drainage groove wall portions in the guide rail, wherein the drainage groove wall portion near an inner side in the vehicle width direction in the pair of drainage groove wall portions is provided with an opening or a recess in a continuous manner, and the drainage member is inserted into the opening or the recess.

[0008] According to the above structure, the drainage member is inserted into the opening or the recess of the drainage groove wall portion of the guide rail, and therefore there is no need to enlarge the space in the up-down direction to accommodate the drainage member, thereby reducing the overall height of the sunroof device.

[0009] Moreover, in the present invention, preferably, a lower edge of the opening is inclined in such a manner that the lower edge of the opening faces downward as it approaches the guide rail drainage groove side, and a bottom wall of the drainage member has a first portion and a second portion arranged sequentially from an outer side to an inner side in the vehicle width direction, and when the drainage member is attached to the guide rail, at least an upper end of the first portion abuts against the lower edge of the opening, and the first portion is inclined such that the first portion faces downward as it approaches the guide rail drainage groove side.

[0010] According to the above structure, the first portion of the bottom wall of the drainage element is inclined such that the first portion faces downward as it approaches the guide rail drainage groove side and is inserted into the opening at the bottom edge, which is inclined in the same way. Thus, the water flowing from the panel drainage element can be guided to flow evenly into the guide rail drainage groove, and the water flow velocity can be increased to increase the drainage volume.

[0011] In addition, in the present invention, preferably, the second portion of the bottom wall is inclined such that the second portion faces downward as it approaches the side of the guide rail drainage groove when the drainage member is mounted on the guide rail.

[0012] Further, according to the above structure, the water flowing out of the panel drainage component can be guided to flow smoothly into the guide rail drainage groove without being retained in the drainage member.

[0013] Furthermore, in the present invention, preferably, an inclination angle of the first portion relative to a horizontal direction is larger than an inclination angle of the second portion relative to a horizontal direction.

[0014] According to the above structure, the water flow velocity through the second section can be further increased, and the water can be more evenly discharged into the guide rail drainage groove.

[0015] In addition, in the present invention, preferably, a recess portion in which the drainage member is embedded is formed in a wall portion located on the inner side in the vehicle width direction relative to the pair of drainage groove wall portions in the guide rail.

[0016] According to the above structure, since the recess portion in which the drainage member is embedded is formed, it is not necessary to provide a space for disposing the drainage member above the guide rail, so that the overall height of the sunroof device can be reduced.

[0017] Moreover, in the present invention, the drainage member preferably has a pair of side walls extending in the vehicle width direction and projecting upward from the bottom wall on both sides in the front-rear direction, and projections are provided on the pair of side walls, respectively, wherein, when the drainage member is mounted on the guide rail, the pair of side walls abuts against the drainage groove wall portion provided with the opening or the recess from the inside in the vehicle width direction, and the projection engages with the wall portion in the guide rail from the outside in the vehicle width direction in which the recess portion is formed, so that the drainage member is fixed to the guide rail.

[0018] According to the above structure, the movement of the drainage member in the vehicle width direction is restricted by the drainage groove wall portion and the guide rail wall portion, so that the drainage member can be stably attached to the guide rail of the sunroof device. Furthermore, such a simple engagement structure can facilitate the installation of the drainage member. Furthermore, by providing a pair of side walls, the drainage member can prevent water flowing into the drainage member from entering the vehicle interior from both sides in the front-rear direction.

[0019] In addition, in the present disclosure, preferably, on an inner side of the second portion of the floor wall in the vehicle width direction, a base end side wall extending in the front-rear direction and extending upward from the second portion is provided, and when the drainage member is mounted on the guide rail, the base end side wall is arranged on the inner side in the vehicle width direction relative to the two end portions in the vehicle width direction of the panel drainage component.

[0020] According to the above structure, the drainage member is provided in the form of a drawer having a base end side wall and two side walls, so that the intrusion of water flowing into the drainage member into the interior of the vehicle can be more reliably prevented.

[0021] Furthermore, in the present invention, the sunroof device preferably includes a sunroof panel, the sunroof panel covering the sunroof opening and including a front panel and a rear panel arranged in the front-rear direction, and at least one of the front panel and the rear panel is slidable by being guided over the pair of guide rails, and the panel drainage component is arranged between the front panel and the rear panel.

[0022] Furthermore, in the present invention, preferably, the guide rail drainage groove also serves as a sliding groove for sliding a slider of at least one of the front panel and the rear panel.

[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.

[0027] The front panel 2 and the rear panel 3 cover the sunroof opening 7 of the sunroof device 1 and are arranged in the front-rear direction X. The front panel 2 and the rear panel 3 each have an approximately rectangular shape, for example, when viewed from above. In addition, at least one of the front panel 2 and the rear panel 3 may be translucent, for example, it may transmit light completely or selectively transmit a portion of the light, and they may also have the function of blocking ultraviolet rays. In addition, the front panel 2 and the rear panel 3 may be made of any known panel material, such as glass, etc.

[0028] In addition, the front panel 2 and the rear panel 3 can each slide in the front-to-rear direction X of the vehicle along with the movement of the associated slider (not shown). However, the adjustment of the front panel 2 and the rear panel 3 is not limited to this. Alternatively, one of the front panel 2 and the rear panel 3 may move in the front-to-rear direction X of the vehicle along with the movement of the associated 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 and move in conjunction with the other in the front-to-rear direction X of the vehicle.

[0029] As in the Fig. 2 to 4, a pair of guide rails 4 can be made of metals such as aluminum and aluminum alloys, but the material of the guide rail is not limited thereto. As long as the function required of the guide rail can be achieved, the material of the guide rail is not specifically limited. A pair of guide rails 4 extend along the front-rear direction X of the vehicle and are respectively arranged on both sides of the sunroof opening 7 in the vehicle width direction Y. A pair of guide rails 4 guides at least one of the front panel 2 and the rear panel 3 to move them in the front-rear direction X.Specifically, a pair of guide rails 4 are each provided with a sliding groove 43, and a slider of at least one of the front panel 2 and the rear panel 3 slides in the sliding groove 43, thereby moving at least one of the front panel 2 and the rear panel 3 in the front-rear direction X. In addition, each guide rail 4 is provided with only one guide rail drainage groove 41 extending along the front-rear direction X, and the guide rail drainage groove 41 drains water that enters the vehicle interior from the sunroof device 1 to the outside of the vehicle. The guide rail drainage groove 41 is formed by a pair of drainage groove wall portions 41a and 41b in the guide rail 4. In this embodiment, the guide rail drainage groove 41 also serves as a sliding groove 43 for the sliding of a slider of the front panel 2 and the rear panel 3.However, in other embodiments, the guide rail drainage groove and the sliding groove may be provided separately.

[0030] In addition, as described in the Fig. 3 and Fig. 4, an opening 42 is provided in a continuous manner in the drainage groove wall portion 41a near an inner side of the vehicle width direction Y in the pair of drainage groove wall portions 41a and 41b, and the opening 42 is provided for inserting the drainage member 6. The opening 42 can be formed, for example, by chamfering the drainage groove wall portion 41a. The lower edge 42a of the opening 42 is inclined such that the lower edge 42a faces downward as it approaches the guide rail drainage groove 41 side. Here, the lower edge 42a of the opening 42 does not strictly refer to the lower edge of the opening on the drainage groove wall portion 41a, but also includes a portion on the same inclined surface formed near the drainage groove wall portion 41a by the same cutting method, etc., and connected to the lower edge of the drainage groove wall portion 41a.

[0031] In addition, a recess portion 45 in which the drainage member 6 is embedded is formed in a wall portion 44 of the guide rail 4, which is located on an inner side in the vehicle width direction Y relative to the pair of drainage groove wall portions 41a and 41b.

[0032] As in the Fig. 1 and Fig. 2, the panel drainage component 5 is arranged between the front panel 2 and the rear panel 3, extends in the vehicle width direction Y, and passes through the sunroof opening 7. The panel drainage component 5 is a component for draining water between the front panel 2 and the rear panel 3 to the guide rail 4. A panel drainage groove 51 is provided in the panel drainage component 5 and extends in the vehicle width direction Y. As shown by the arrows in the Fig. 1 and Fig. 2, water flows into the panel drainage component 5 from above and then flows outward along the panel drainage component 5 in the vehicle width direction Y.

[0033] As in the Fig. 2 and Fig. 4, a pair of drainage elements 6 is attached to a pair of guide rails 4. The two drainage elements 6 are each arranged below two end portions of the panel drainage component 5 in the vehicle width direction Y. In the front-rear direction X of the vehicle, the two drainage elements 6 and the two end portions of the panel drainage component 5 are each arranged at approximately the same position in the vehicle width direction Y. The drainage element 6 is configured such that water flowing from the panel drainage groove 51 of the panel drainage component 5 is guided through the drainage element 6 into the guide rail drainage groove 41 of the guide rail 4, as indicated by the arrows in the Fig. 2 and Fig. 4 shown.

[0034] As in the Fig. 3 and Fig. 4, the drainage member 6 has a drawer shape and includes a bottom wall 61 inclined such that the bottom wall 61 faces downward as it approaches the guide rail drainage groove 41 side when the drainage member 6 is mounted on the guide rail 4; a pair of side walls 62 projecting upward from the bottom wall 61 and extending in the vehicle width direction Y on both sides in the front-rear direction X of the drainage member 6; and a base end side wall 63 projecting upward from the bottom wall 61 and extending in the front-rear direction X on an inner side of the bottom wall 61 in the vehicle width direction Y.

[0035] The bottom wall 61 of the drainage member 6 has a first portion 611 and a second portion 612, which are successive from an outer side to an inner side in the vehicle width direction Y. When the drainage member 6 is mounted on the guide rail 4, an upper surface of the first portion 611 abuts the lower edge 42a of the opening 42, and the first portion 611 is inclined such that the first portion 611 faces downward as it approaches the guide rail drainage groove 41 side, and the second portion 612 is inclined such that the second portion 612 faces downward as it approaches the guide rail drainage groove 41 side. The inclination angle of the first portion 611 relative to a horizontal direction is greater than the inclination angle of the second portion 612 relative to a horizontal direction.

[0036] A projection 64 is provided at a position near the base end side wall 63 of each of the pair of side walls 62, and the projection 64 is used to engage with the wall portion 44 of the guide rail 4 to fix the drainage member 6 to the guide rail 4. However, the setting position of the projection 64 is not limited to the above position of the side wall 62, and the projection 64 may be provided at any suitable position of the side wall 62 as long as the drainage member 6 can be stably fixed to the guide rail 4.

[0037] The base end side wall 63 protrudes upward from the second portion 612 of the bottom wall 61 and extends along the front-rear direction X. When the drainage member 6 is attached to the guide rail 4, the base end side wall 63 is arranged on the inner side of the vehicle width direction Y relative to the two end portions of the panel drainage component 5 in the vehicle width direction Y.

[0038] The following describes the attachment of the drainage element 6 to the guide rail 4. The drainage element 6 is embedded from the inside in the vehicle width direction Y into the recessed portion 45 of the wall portion 44 of the guide rail 4, and then the recessed portion 45 is used to guide the drainage element 6 to move to the outside in the vehicle width direction Y, as indicated by the arrow in Fig.3, and the side of the drainage member 6 opposite the base end side wall 63 is inserted into the opening 42 on the drainage groove wall portion 41a of the guide rail 4 until the first portion 611 of the bottom wall 61 of the drainage member 6 is supported on the lower edge 42a of the opening 42 and the pair of side walls 62 abuts against the drainage groove wall portion 41a from the inner side in the vehicle width direction Y, and the projection 64 provided on the side wall 62 of the drainage member 6 rides over the recess portion 45 and engages with the wall portion 44 of the guide rail 4 from the outer side in the vehicle width direction Y. Thus, the attachment of the drainage member 6 to the guide rail 4 is completed.

[0039] The effects of this embodiment are described below.

[0040] According to the above-described structure of the sunroof device of the present invention, only one guide rail drainage groove 41 is provided on the guide rail 4, and water drained from the panel drainage groove 51 of the panel drainage component 5 is guided into the above guide rail drainage groove 41 via the separately provided drainage member 6, so that the drainage of the guide rail and the drainage of the sunroof panel are achieved simultaneously.Compared with a case where two drainage grooves, namely a drainage groove for guide rail drainage and a drainage groove for panel drainage for receiving water from the panel drainage component, are provided on the guide rail, the cross-sectional structure of the guide rail can be simplified, the dimension of the guide rail in the vehicle width direction can be reduced, the manufacturing cost of the guide rail can be reduced, and the area of ​​the sunroof opening can be increased, so that the commercial quality of the sunroof device is improved.

[0041] Furthermore, in this embodiment, the opening 42 is provided in a continuous manner in the drainage groove wall portion 41a near the inner side in the vehicle width direction Y, and the drainage member 6 is inserted into the opening 42. Therefore, it is not necessary to enlarge the space in the up-down direction Z to accommodate the drainage member 6, so that the overall height of the sunroof device 1 is reduced.

[0042] Furthermore, in this embodiment, the lower edge 42a of the opening 42 is inclined such that the lower edge 42a faces downward as it approaches the side of the guide rail drainage groove 41, and the first portion 611 of the bottom wall 61 of the drainage member 6, which abuts the lower edge 42a of the opening 42, is also inclined such that the first portion 611 faces downward as it approaches the side of the guide rail drainage groove 41 when the drainage member 6 is mounted on the guide rail 4.

[0043] Therefore, the water flowing out of the panel drainage component 5 can be guided to flow smoothly into the guide rail drainage groove 41, and the water flow velocity can be increased to increase the drainage amount.

[0044] Furthermore, in this embodiment, the second portion 612 of the bottom wall 61 is inclined such that the second portion 612 faces downward as it approaches the guide rail drainage groove 41 side when the drainage member 6 is mounted on the guide rail 4. Thus, the water flowing from the panel drainage component 5 can be directed to flow smoothly into the guide rail drainage groove 41 without being retained in the drainage member 6.

[0045] Furthermore, in this embodiment, the inclination angle of the first portion 611 relative to the horizontal direction is greater than the inclination angle of the second portion 612 relative to the horizontal direction. Thus, the water flow velocity through the second portion 612 can be further increased, and water can be more evenly discharged into the guide rail drainage groove 41.

[0046] In addition, in this embodiment, a recess portion 45 in which the drainage member 6 is embedded is formed in the wall portion 44 of the guide rail 4, and therefore, it is not necessary to provide space for disposing the drainage member 6 above the guide rail 4, so that the overall height of the sunroof device 1 can be reduced.

[0047] In addition, in this embodiment, the drainage member 6 has a pair of side walls 62 extending along the vehicle width direction Y and projecting upward from the bottom wall 61 on both sides in the front-rear direction X, and the pair of side walls 62 are each provided with projections 64 that engage with the wall portion 44 of the guide rail 4.

[0048] Thus, the movement of the drainage member 6 in the vehicle width direction Y is restricted by the drainage groove wall portion 41a and the wall portion 44 of the guide rail 4, so that the drainage member 6 can be stably attached to the guide rail 4 of the sunroof device 1. Furthermore, such a simple engagement structure can facilitate the installation of the drainage member 6. Furthermore, by providing a pair of side walls 62, the drainage member 6 can prevent water flowing into the drainage member 6 from entering the vehicle interior from both sides in the front-rear direction.

[0049] Additionally, in this embodiment, the drainage member 6 has a base-end side wall 63 extending in the front-rear direction X and projecting upward from the second portion 612 on an inner side of the second portion 612 of the floor wall 61 in the vehicle width direction Y. When the drainage member 6 is mounted on the guide rail 4, the base-end side wall 63 is disposed on the inner side in the vehicle width direction Y relative to the two end portions of the panel drainage component 5 in the vehicle width direction Y. Thus, the drainage member 6 is provided in a drawer shape with the base-end side wall 63 and two side walls 62, so that water flowing into the drainage member 6 can be more reliably prevented from intruding into the interior of the vehicle.

[0050] Moreover, in this embodiment, the guide rail drainage groove 41 also serves as a sliding groove 43 for sliding a slider of at least one of the front panel 2 and the rear panel 3. Thus, the cross-sectional shape of the guide rail 4 can be further simplified, the dimension of the guide rail 4 in the width direction can be reduced, and the area of ​​the sunroof opening can be increased.

[0051] The preferred embodiment of the present invention has been described above, but is not limited thereto. Various modifications may be made as follows.

[0052] In the above-mentioned preferred embodiment, the drainage element 6 is inserted into the opening 42 of the drainage groove wall portion 41a and embedded in the recess portion 45 on the wall portion 44 of the guide rail 4.

[0053] However, as long as the drainage element 6 can direct the water from the panel drainage component 5 into the guide rail drainage groove 41 of the guide rail 4, the drainage element 6 can also be installed in other ways. For example, the drainage element can be stretched over the guide rail 4. In this case, it is not necessary to provide the opening 42 and the recess portion 45 on each wall section of the guide rail.

[0054] In the above-mentioned preferred embodiment, the opening 42 into which the drainage element 6 is inserted is provided continuously in the drainage groove wall portion 41a, but the configuration is not limited thereto. Provided that the guide rail 4 for guiding the movement of the sunroof panel is not interfered with, an upwardly open recess may also be provided in the drainage groove wall portion 41a for inserting the drainage element 6.

[0055] In the above-mentioned preferred embodiment, the bottom wall 61 of the drainage member 6 is formed to be inclined as a whole so that the drainage member 6 faces downward as it approaches the guide rail drainage groove 41 side when the drainage member 6 is mounted on the guide rail 4. However, the arrangement of the bottom wall 61 of the drainage member 6 is not limited to the above-described manner. For example, the bottom wall 61 may be arranged horizontally as a whole, or one of the first portions 611 and the second portions 612 of the bottom wall 61 may be arranged horizontally, and the other may be inclined so that the other faces downward as it approaches the guide rail drainage groove 41 side.Furthermore, in the above-mentioned preferred embodiment, the inclination angle of the first portion 611 is greater than the inclination angle of the second portion 612, but the adjustment of the inclination angle is not limited thereto. For example, the inclination angle of the first portion 611 may be equal to the inclination angle of the second portion 612 or smaller than the inclination angle of the second portion 612. Furthermore, the inclination angle of the first portion 611 is preferably the same as the inclination angle of the lower edge 42a, but the adjustment of the inclination angle is not limited thereto. As long as the first portion 611 can abut against the lower edge 42a, the inclination angles of the two are not specifically limited.

[0056] In the above-mentioned preferred embodiment, an upper end of the first portion 611 abuts the lower edge 42a of the opening 42, and the first portion 611 may also extend further into the guide rail drainage groove 41 as long as the drainage of the guide rail drainage groove 41 is not obstructed.

[0057] In the above-mentioned preferred embodiment, the drainage member 6 is formed in a drawer shape having a base-end side wall 63 and a pair of side walls 62 projecting upward from the bottom wall 61. However, the shape of the drainage member 6 is not specifically limited as long as water flowing from the panel drainage component 5 into the drainage member 6 can be prevented from entering the vehicle interior. For example, it is not necessary to provide a base-end side wall to prevent water from entering the vehicle interior as long as the inclination angle of the bottom wall 61 is large enough.

[0058] Moreover, in the above-mentioned preferred embodiment, the projection 64 provided on the side wall 62 of the drainage member 6 is engaged with the wall portion 44 formed with the recess portion 45 in the guide rail 4, so that the drainage member 6 is fixed to the guide rail 4. However, the fixing method of the drainage member 6 and the guide rail is not limited to this; for example, threaded holes may be provided on both the guide rail and the drainage member, and the two may be fixed by threaded members such as screws.

[0059] Furthermore, in the above preferred embodiment, a case is described where the panel drainage component 5 is arranged between the front panel 2 and the rear panel 3. However, the arrangement of the panel drainage component 5 is not limited thereto. The panel drainage component 5 may also be provided between the front panel 2 and the front frame 8 and / or the rear panel 3 and the rear frame 9. In the case of only one sunroof panel, the panel drainage component 5 may be arranged between the sunroof panel and either the front frame or the rear frame.

[0060] The above describes the embodiment of the present invention. However, the present invention is not limited to the above embodiment. Without departing from the main purpose of the present invention, the embodiment obtained by those skilled in the art by appropriately modifying, combining, and deleting the above components is also included in the technical scope to be protected by the present invention.
