Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back door of a vehicle, and more particularly to an improvement in a structure for preventing raindrops. FIG. 4 shows an example of a back door for opening and closing a rear opening O of a van type vehicle. Door body of back door 1
The upper end thereof is rotatably connected to the upper edge of the rear opening O, and is flipped up to a position where it is substantially horizontal with respect to the vehicle body as shown in FIG. In such a back door, the left and right side edges 21 of the window glass 2 provided so as to cover the window opening (FIG. 5) 12 of the back door body 1 are designed as shown in FIG. One extending to the left and right side edges 1a (only one is shown) of the main body 1 is known. In this case, a spacer 5 is provided between the side edge of the window glass 2 and the side edge 1a of the back door main body 1 to maintain a predetermined distance between the window glass 2 and the back door main body 1. ing. More specifically, as shown in FIG. 7, a door side edge frame 11 is provided on a lower surface of a side edge portion 21 of a window glass 2 extending in a vehicle front-rear direction with the back door body 1 flipped up.
The adhesive 3 is interposed between the outer panel 111 and
Window glass 2 is fixed to outer panel 111. A rubber spacer 5 is joined to a lower surface of the side edge portion 21 outside the adhesive 3, and a lower end surface 51 of the spacer 5 is connected to an outer edge of the outer panel 111 which is hemmed to an outer edge of the inner panel 112. It touches the upper edge. A lip portion 52 is formed at a lower end portion of the spacer 5, and the lip portion 52 extends to the side, and a tip 521 extends outside the side edge of the window glass 2. With such a lip portion 52, the rainwater falling on the window glass 2 in a state where the back door body 1 is flipped up and opened is lipped from the side edge 21 of the window glass 2 as shown by a solid arrow in FIG. It falls on the part 52 and drops from the tip 521 toward the road surface. When the door is closed, FIG.
As shown by the dashed line, the weather strip P1 provided on the body panel P at the edge of the rear opening O of the vehicle is pressed against the center of the inner panel 112 to completely prevent rainwater or the like from entering the cargo compartment. I have. [0005] The lip portion 5
If the momentum of the rainwater falling on the top 21 is sufficient, the rainwater drops from the tip 52 of the lip portion 5 toward the road surface as described above. In the case where there is no momentum such as rainwater, such as when falling onto the lip portion 52 due to the opening and lifting of 1, rainwater or the like often pushes the lip tip 521 as shown by a chain line arrow in FIG. There is a problem in that the baggage gets around, travels along the inner panel 112, goes inward in the width direction of the back door body 1, and then drops into the luggage compartment (arrow in FIG. 4) to wet the luggage. Accordingly, the present invention is to solve such a problem. Therefore, even in a case where there is no momentum such as rainwater, the present invention is directed to a vehicle which can surely drop them on a road surface and prevent dripping into a luggage compartment. The purpose is to provide a back door. In order to achieve the above object, according to the present invention, a window opening (12) is coupled to a vehicle body so that the window opening (12) can be flipped up to a position which is substantially horizontal. The formed back door body (1) and the back door body (1) are fixed so as to cover the window opening (12), and the side edges (21) are side edges (21) of the back door body (1). 1a)
Window glass (2) extending to the side of the window glass (2), and interposed between the side edge (21) of the window glass (2) and the side edge (1a) of the back door body (1). ) And a spacer (4) for maintaining a distance between the back door body (1) at a predetermined interval, the back door body (1) is jumped up by the spacer (4). In the state, the first lip portion (42) protruding downward at a position away from the side edge (1a) of the back door body (1) to the side.
And a second lip portion (43) disposed above the first lip portion (42) and protruding laterally beyond the side edge (21) of the window glass (2) and the first lip portion (42). Are formed. In the present invention, the rainwater falling on the window glass with the back door body being flipped up and opened falls relatively vigorously from the side edge of the window glass onto the second lip portion, and the rain water falls on the second lip portion. Dripping from the tip toward the road surface. On the other hand, if the rainwater or the like that has accumulated in the window glass has no momentum such as when the backdoor body is flipped up and opened and the rainwater or the like falls down, the rainwater or the like touches the tip of the second lip portion. It goes around to the first lip. Since the first lip portion protrudes downward, water droplets such as rainwater that have reached the tip of the first lip portion do not rise, but drop away from the tip of the first lip portion toward a lower road surface. This prevents a problem such as impetuous rainwater or the like from dropping into the luggage compartment along the side edge of the back door body and causing the luggage to get wet. The tip (42) of the first lip (42)
It is preferable that 1) protrude below the side edge (1a) of the back door body (1). With this configuration, even when the distance between the tip of the first lip and the side edge of the back door body cannot be sufficiently separated, it is possible to prevent water droplets from moving from the tip of the first lip to the side edge of the back door body. can do. [0010] The symbols in parentheses indicate the correspondence with specific means described in the embodiments described later. FIG. 1 is a cross-sectional view of a side edge portion of a back door body showing an embodiment of the present invention, and is a view corresponding to FIG. The reference numerals are attached. In FIG. 1, an adhesive 3 is interposed between an outer panel 111 of a door side frame 11 and a lower surface of a side edge 21 of a window glass 2 extending in a vehicle front-rear direction with the back door body 1 flipped up. Thus, the window glass 2 is fixed to the outer panel 111. A rubber spacer 4 is joined to the lower surface of the window glass side edge 21 outside the adhesive 3. The lower end surface 41 of the spacer 4 is in contact with the upper surface of the outer edge of the outer panel 111 as shown in FIG. The outer edge of the inner panel 112 is hemmed to the outer edge of the outer panel 111. The spacer 4 has a first lip portion 42 and a second lip portion 43 disposed above the first lip portion 42.
Is formed. Here, the first lip portion 42 has an inner panel 112 and an outer panel 11 which are hemmed to each other.
1, extending downward from the lower end of the spacer 4 located outside the side edge 1a of the back door body 1,
The tip 421 protrudes below the side edge 1 a of the back door body 1. The second lip portion 43 extends outward from the outer surface of the upper end of the spacer 4 and has a tip 431.
Protrudes laterally beyond the side edge 21 of the window glass 2 and the tip 421 of the first lip portion 42. In the back door having such a structure, the back glass main body 1 is flipped up and the window glass 2 is opened.
The rainwater falling upward falls relatively vigorously onto the second lip portion 43 from the side edge 21 of the window glass 2 as shown by the solid arrow in FIG. 2, and from the tip 431 of the second lip portion 43 toward the road surface. Drip. On the other hand, when the rainwater or washing water accumulated in the window glass 2 falls onto the second lip portion 43 with the back door body 1 being flipped up and opened, the rainwater or the like has no momentum and the chain line in FIG. As indicated by the arrow, rainwater or the like goes around the tip 431 of the second lip portion 43 and heads toward the first lip portion 42. Since the first lip portion 42 protrudes downward as described above, as shown in FIG.
The water droplet W such as rainwater that has reached the tip of the first lip portion 2a does not rise along the inner side surface 42b of the first lip portion 42, but stays at the tip 421 and gathers there.
1 and dripping toward the lower road surface. Thereby, it is possible to prevent a problem that rainwater or the like drops from the side edge 1a of the back door main body 1 along the inner panel 112 (FIG. 2) into the luggage compartment and the luggage gets wet. In the present embodiment, in particular, the tip 421 of the first lip portion 42 protrudes below the side edge 1a of the back door body 1, so that the tip 421 of the first lip portion 42 is formed.
Even when the side edge 1a of the back door main body 1 cannot be sufficiently separated in the inward and outward directions (the left-right direction in FIG. 2), the side edge 1a of the back door main body 1 from the tip 421 of the first lip portion 42.
It is possible to reliably prevent water droplets from migrating. As described above, according to the back door of the vehicle of the present invention, even when there is no momentum such as rainwater, these are surely dropped onto the road surface, and the rainwater and the like enter the cargo room. Dropping can be prevented.
