[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment described herein. In all drawings, the same elements are given the same reference numerals, and duplicated explanations will be omitted. In the following description, unless otherwise specified, terms indicating directions and orientations such as front, back, left, right, up, down, etc. indicate directions and orientations related to the vehicle. In each drawing, the arrow FR points forward, the arrow UP points upward, and the arrow LH points leftward.

[0017] This embodiment relates to a drainage structure for a vehicle body that drains condensation water Cw that flows down along the inner surface of a back door glass 16 (see Figs. 1 and 2) as an example of a back glass to the outside of the vehicle. Note that a back door panel 14 described below is an example of a body panel.

[0018] 1 is a perspective view showing the rear of a vehicle 10 according to an embodiment. The vehicle 10 is equipped with a tailgate 12. The tailgate 12 is a flip-up type opening and closing body that opens and closes a rear opening of the vehicle 10. The tailgate 12 is attached to a roof panel of the vehicle body via a hinge (not shown) so as to be able to swing up and down. The tailgate 12 is equipped with a tailgate panel 14 and a tailgate glass 16.

[0019] Fig. 2 is a cross-sectional view of the rear part of the vehicle taken along line AA in Fig. 1. The back door panel 14 includes an outer panel 22 made of a steel plate and disposed on the outside of the vehicle, and an inner panel 20 made of a steel plate and disposed on the inside of the vehicle. The outer panel 22 and the inner panel 20 form a closed cross section.

[0020] The back door 12 includes a trim 18 disposed on the vehicle inner side of the inner panel 20. The inner panel 20 and the trim 18 form a closed cross section. An electrical equipment connector 80 is disposed between the inner panel 20 and the trim 18. The electrical equipment is, for example, electrical / electronic equipment disposed on the back door 12, such as a tail lamp, a back lamp, a wiper, a camera, etc. The electrical equipment connector 80 is, for example, a component for connecting and conducting electric wires (power lines and signal lines) for the electrical / electronic equipment to each other, or between the electrical / electronic equipment and electric wires.

[0021] The back door glass 16 is attached to the back door panel 14 (outer panel 22) so as to incline downward from the front to the rear. FIG. 3 is a schematic diagram for explaining the mounting structure of the back door glass 16, showing a rear view of the vehicle. Line a1-a1 in FIG. 3 indicates the position corresponding to line AA in FIG. 1. In FIG. 3 and FIG. 4 described later, the molding 32 is shown in a simplified form. The back door glass 16 is attached to an opening 15 provided in the back door panel 14. An adhesive portion 30 (shown by a dotted line in FIG. 3) is provided in a continuous manner on the periphery of the back door glass 16 on the vehicle interior side. The adhesive portion 30 is made of a hardened urethane adhesive.

[0022] The adhesive portion 30 is located between the back door glass 16 and the back door panel 14 (outer panel). The adhesive portion 30 adheres the peripheral portion of the back door glass 16 to the peripheral portion of the opening 15 of the back door panel 14. This adhesive portion 30 can prevent water from entering the peripheral portion of the opening 15 of the back door panel 14 from outside the vehicle.

[0023] Fig. 4 is an enlarged view of a left-right central region of the lower edge portion of the back door glass 16 in Fig. 3. The adhesive portion 30 has a passage 31 in the left-right central region of the lower edge portion (lower peripheral portion) of the back door glass 16 that allows condensation water Cw that flows down along the inner surface of the back door glass 16 to pass toward the molding 32.

[0024] 3, a molding 32 is provided on the lower edge of the back door glass 16 on the vehicle interior side, closer to the edge of the back door glass than the adhesive portion 30. The molding 32 is provided along the lower edge of the back door glass 16. The molding 32 is located between the back door glass 16 and the back door panel 14.

[0025] FIG. 6 is a perspective view of the molding 32 attached to the back door glass 16, seen from below, showing only the central region of the molding 32 in the left-right direction. The line a2-a2 in FIG. 6 indicates the position corresponding to the line AA in FIG. 1. The molding 32 includes a support portion 54 and a top plate portion 50 disposed above the support portion 54. The support portion 54 is located between the back door panel (not shown in FIG. 6) and the back door glass 16, and supports the back door glass 16 with respect to the back door panel. The lower end surface of the support portion 54 is in contact with the back door panel (not shown in FIG. 6). The top plate portion 50 includes a front portion 52 that protrudes forward from the support portion 54, and a rear portion 56 that protrudes rearward from the support portion 54. The upper surface of the front portion 52 of the top plate portion 50 is adhered to the inner surface of the back door glass 16 by double-sided tape. The molding 32 is a part made of rubber or resin.

[0026] A water drainage hole 64 is formed in the molding 32 by cutting out a part of the support portion 54. The water drainage hole 64 is a passage for discharging condensed water Cw on the inner surface of the back door panel 14 to the outside of the vehicle. In the following, the part of the molding 32 where the water drainage hole 64 is formed is referred to as a water drainage portion 32B, and the part other than the water drainage portion 32B is referred to as a general portion 30A. In FIG. 6, the water drainage portion 32B is shown filled with a dot pattern.

[0027] Here, the process of assembling the back door glass 16 to the back door panel 14 will be described with reference to FIG. 3. First, the molding 32 is attached to the inner surface of the back door glass 16. This is done by bonding the upper surface of the top plate portion 50 of the molding 32 to the inner surface of the back door glass 16 with double-sided tape. Then, a urethane adhesive constituting the adhesive portion 30 is applied to the peripheral portion of the inner surface of the back door glass 16. Next, with the inner surface of the back door glass 16 facing downward, the back door glass 16 is attached to the peripheral portion of the opening 15 (see FIG. 3) of the back door panel 14 from the outside of the vehicle. At this time, the molding 32 functions to prevent the back door glass 16 from being displaced at the lower edge of the back door glass 16 until the urethane adhesive hardens. The molding 32 also plays a role in improving the appearance of the lower edge of the back door glass 16 after the back door glass 16 is assembled.

[0028] Next, the adhesive portion 30 and the molding 32 will be described in more detail. As shown in Figs. 3 and 4, the adhesive portion 30 extends continuously from a starting end 30S to a terminal end 30E on the peripheral portion of the back door glass 16. The starting end 30S and the terminal end 30E of the adhesive portion 30 are located on the lower peripheral portion of the back door glass 16 and are located in the central region of the back door glass 16 in the left-right direction. In addition, as shown in Fig. 4, the starting end 30S and the terminal end 30E of the adhesive portion 30 are provided at positions shifted from each other in the left-right direction. As a result, the adhesive portions 30 are provided partially overlapping on the lower peripheral portion of the back door glass 16. The adhesive portions 30 are provided at intervals in the up-down direction in the overlapping region, forming a passage 31 for discharging the condensed water Cw.

[0029] Moreover, the adhesive portion 30 is inclined downward toward the starting end 30S and toward the ending end 30E. This makes it easier for the condensation water Cw to flow toward the passage 31 and to flow through the passage 31 toward the drainage hole 64 of the molding 32. In addition, since the adhesive portions 30 are partially overlapped, it is possible to prevent water from outside the vehicle from crossing the adhesive portions 30 and entering the inside of the vehicle.

[0030] The molding 32 includes a water drainage portion 32B (see FIG. 6 for detailed structure) in which a water drainage hole 64 is formed, and general portions 32A provided on both left and right sides of the water drainage portion 32B. The water drainage portion 32B is located at the center of the back door glass 16 in the left and right direction. The two general portions 32A (specifically, the support portions 54 of the general portions 32A) on both sides of the water drainage portion 32B are each inclined downward toward the water drainage portion 32B, as shown in FIG. 4. This makes it easier for the condensation water Cw that reaches the general portions 32A (the support portions 54 of the general portions 32A) to flow toward the water drainage holes 64.

[0031] 6, general portion 32A has a generally T-shaped cross section. General portion 32A includes a support portion 54 and a top plate portion 50. Top plate portion 50 includes a front portion 52 and a rear portion 56. General portion 32A is manufactured by extrusion molding.

[0032] The water draining portion 32B includes a support portion 54 and a top plate portion 50, similar to the general portion 32A. A part of the support portion 54 of the water draining portion 32B is cut out, thereby forming a water draining hole 64. In addition to the support portion 54 and the top plate portion 50, the water draining portion 32B further includes a lip 58 that covers the rear of the support portion 54. The lower right of FIG. 6 shows a side surface of the water draining portion 32B (the side surface at the position where it is joined to the general portion 32A (the position indicated by the arrow B)). FIG. 5 is an enlarged cross-sectional view showing the periphery of the water draining hole 64 in FIG. 2, with the adhesive portion 30 omitted. Note that in FIGS. 2 and 5, the cross section of the lip 58 should actually be shown, but in FIG. 2, the lip 58 is omitted, and in FIG. 5, the outer contour of the lip 58 is shown by a broken line. As shown in FIG. 5, the tip of the lip 58 is in contact with the back door panel 14 (the outer panel 22). The lip 58 covers the rear of the drain hole 64 in order to prevent rainwater Rw (see FIG. 5) and the like from entering the inside of the vehicle through the drain hole 64 from the outside of the vehicle.

[0033] As shown in Fig. 5, the upper surface of the top plate portion 50 (front portion 52) of the molding 32 and the back door glass 16 are adhered with double-sided tape to form a molding adhesion portion 26. In the figure, the member indicated by the reference numeral 26 is the double-sided tape. The molding adhesion portion 26 is provided so as to extend along the lower edge portion of the back door glass 16.

[0034] Here, as shown in FIG. 6, a notch 60 is provided in the front part of the top plate part 50 located above the water drainage hole 64. As shown in FIG. 5, the front surface 51 of the notch 60 is located at the front end of the molding bonding part 26. That is, the front part of the top plate part 50 is notched up to the position of the front end of the molding bonding part 26. The molding bonding part 26 extends along the lower edge part of the back door glass 16 at a position spaced apart from the front end of the top plate part 50 except for the notch 60. Therefore, at the position of the top plate part 50 except for the notch 60, a gap is present between the top plate part 50 and the back door glass 16 in front of the molding bonding part 26. Condensed water Cw may enter the gap, but the presence of the notch 60 allows the condensed water Cw that has entered the gap to be smoothly guided to the water drainage hole 64 through the notch 60.

[0035] The molding 32 can be manufactured by, for example, insert molding. For example, two general parts 32A of the molding 32 are made in advance by extrusion molding. Then, the two general parts 32A are inserted into a metal mold including a mold for the drainage parts 32B of the molding 32, and a rubber material or a resin material is injected into the metal mold to fill it. Then, the molded product is removed from the metal mold. This makes it possible to make the drainage parts 32B and obtain the molding 32 in which the drainage parts 32B and the two general parts 32A are integrated.

[0036] Next, the operation and effect of the drainage structure for the vehicle body according to this embodiment will be described.

[0037] As shown in Fig. 2, the condensation water Cw generated on the inner surface of the back door glass 16 flows down along the inner surface of the back door glass 16 due to the action of gravity. At this time, as shown in Fig. 4, the condensation water Cw reaches the adhesive part 30 and can flow out to the molding 32 side through the passage 31 of the adhesive part 30. The condensation water Cw is then guided to the drainage hole 64 of the molding 32 and can pass through the drainage hole 64. At this time, as shown in Figs. 5 and 6, since the rear of the drainage hole 64 is covered with the lip 58, the condensation water Cw can flow out of the vehicle from both the left and right sides of the lip 58 after reaching the lip 58, as shown in Fig. 6.

[0038] Furthermore, according to the embodiment described above, the lip 58 is provided and the adhesive portion 30 is partially overlapped as shown in FIG. 4, so that rainwater Rw (see FIG. 5) and the like from outside the vehicle can be prevented from entering the inside of the vehicle.

[0039] Fig. 9 is a cross-sectional view showing a part of a back door 112 of the prior art, showing the conventional structure of the portion shown in Fig. 2 of this embodiment. In the conventional structure, the lower edge of the back door glass 16 is sealed by the adhesive part 30, and no passage for condensation water is provided. Also, in the conventional structure, the molding 132 is composed only of the general part 32A described above, and no drainage hole is provided.

[0040] In such a conventional structure, the condensation water Cw flows down along the inner surface of the back door glass 16 due to gravity, passes through the gap between the back door glass 16 and the trim 18, and reaches the adhesive part 30. The condensation water Cw accumulates in front of the adhesive part 30, and may drip through the gap 90 between the trim 18 and the back door panel 14 and the gap 91 between the inner panel 20 and the outer panel 22. There is a concern that the condensation water Cw that enters the space between the trim 18 and the inner panel 20 may directly reach the electrical equipment connector 80, as shown in FIG. 9. In addition, since the inner panel 20 has a plurality of holes, there is a concern that the condensation water Cw that enters the space between the inner panel 20 and the outer panel 22 may also reach the electrical equipment connector 80 through the holes in the inner panel 20. If the condensation water Cw reaches the connector 80 in this way, there is a risk of a short circuit or the like occurring.

[0041] However, according to the embodiment described above, as shown in FIG. 2, the condensation water Cw that flows down along the inner surface of the back door glass 16 can be discharged outside the vehicle, thereby eliminating or reducing the risk of the condensation water Cw reaching the connector 80 as in the conventional structure.

[0042] In the embodiment described above, as shown in FIG. 6, the drainage portion 32B of the molding 32 includes the lip 58 and the notch 60 of the top plate portion 50. However, the drainage portion 32B may be configured to omit at least one of the lip 58 and the notch 60. FIG. 7 is a perspective view showing the rear of a vehicle 10A according to another embodiment. The vehicle 10A in FIG. 7 is different from the vehicle 10 in FIG. 1 in that a rear garnish 70 is attached, and the other configurations are the same. The rear garnish 70 is disposed below the back door glass 16 and near the center in the left-right direction. In the vehicle 10A having such a rear garnish 70, the rear of the drainage hole 64 (see FIG. 6) of the molding is covered by the rear garnish 70, so that even if the lip 58 is not provided on the molding 32, the rear garnish 70 can suppress the intrusion of water into the drainage hole 64 from the outside of the vehicle. Therefore, the vehicle 10A having the rear garnish 70 may adopt a molding 32 without the lip 58.

[0043] In the above-described embodiment, the vehicle 10, 10A has a back door 12. However, the vehicle may be an automobile such as a sedan that does not have a back door. Even in such a vehicle, the above-described embodiment can be adopted to prevent condensation water from entering unintended locations. In this case, the back door glass 16 is replaced with a back window glass (an example of a back glass), and the back door panel 14 is replaced with a rear body panel (an example of a body panel) located at the rear of the vehicle.

[0044] Next, a modified example will be described. FIG. 8 is a diagram showing a drainage structure of a vehicle body according to a modified example, and shows a configuration in which the part shown in FIG. 4 is modified. As shown in FIG. 8, the adhesive part 30 may have a plurality of passages 31A for condensed water Cw. Also, as shown in FIG. 8, the adhesive part 30 may be in a form that extends straight in the left-right direction (not inclined downward). Also, as shown in FIG. 8, the molding 32 may be in a form that extends straight in the left-right direction (not inclined downward). As shown in FIG. 8, the passage 31A of the adhesive part 30 and the drainage hole 64 of the molding 32 may be provided at positions offset in the left-right direction. Even with such a modified example, it is possible to obtain the same or similar effects as those of the embodiment described above. [Explanation of symbols]
