Description

[Detailed Description of the Invention] This invention relates to an improvement in the rear body structure of an automobile in which a rear gate is provided on the back of the vehicle body.

Generally, as shown in Fig. 1, an automobile such as a passenger car has a configuration in which a rear gate 2 that can be opened and closed and a pair of left and right rear combination lamps (rear lamps) 3 are respectively disposed on the rear surface of a car body 1. is being developed. By the way, as shown in FIG. 2, this type of vehicle has a weather strip 5 formed of an elastic material such as rubber around the entire periphery of the rear opening 4 of the rear body that is opened and closed by the rear gate 2. is installed, and when the rear gate 2 is closed, this weather strip 5 is pressed against the inner surface of the peripheral edge of the rear gate 2, preventing rainwater etc. from flowing into the passenger compartment from the joint between the peripheral edge of the rear opening 4 of the rear body and the rear gate 2. The system is designed to prevent the infiltration of However, poor adhesion of the weather strip 5 tends to occur in the upper part of the rear opening 4 of the rear body or in the vicinity of each corner of the rear opening 4, and water from the outside flows into the passenger compartment from the part where the adhesion is poor. There was a risk that it might get inside. In this case, at the peripheral edge of the rear opening 4 in the rear body, the outer panel on the outside and the inner panel on the inside are joined via a joint such as a flange, and the weather strip 4 is connected to the outer panel and the inner panel. Fitted into the joint. Therefore, rainwater, etc. that has entered the interior of the vehicle through the poorly adhered portion of the weather strip 4 is guided downward along the joint between the inner panel and the outer panel, and
As shown in the figure, the rear opening 4 in the rear body
It is collected at the joints 7a and 7b between the rear end outer 6a and the rear end inner 6b, which are the lower parts of the rear end, and flows into the passenger compartment through the joints 7a and 7b or along the inner surface of the rear end inner 6b. This caused problems such as dirt and rust on the floor of the trunk compartment inside the vehicle.

Therefore, as shown in FIG.
A notch 8 is locally provided in b, and rainwater etc. that have entered the vehicle interior are discharged to the outside through this notch 8 as shown by the solid line arrow in the same figure, or as shown in FIG. 4. In addition to providing a drainage hole 9 in the rear end inner 6b, a drainage bead 11 is also formed in the rear floor 10 to drain rainwater that has entered the interior of the vehicle, as shown by the solid line arrow in the figure. The liquid was discharged to the outside through the hole 9 and the bead portion 11. However, in the case of the conventional structure described above, when washing the car or in the case of heavy rain, rainwater etc. may flow back into the vehicle interior through the notch 8, hole 9, bead 11, etc. There were problems such as mud being kicked up and exhaust gas emitted from the tail pipe flowing into the passenger compartment.

This idea was created in consideration of the above circumstances, and its purpose is to ensure that rainwater, etc. that has entered the interior of the vehicle due to poor adhesion of the weather strip, etc., can be reliably drained to the outside. It is an object of the present invention to provide a rear body structure for an automobile that can prevent backflow of rainwater etc. from the outside side to the inside of the vehicle interior and prevent exhaust gas etc. from flowing into the inside of the vehicle interior.

An embodiment of this invention will be described below with reference to FIGS. 5 to 7. Note that in FIGS. 5 to 7, the same parts as in FIGS. 1 to 4 are designated by the same reference numerals, and the explanation thereof will be omitted. That is, in this invention, a rear opening 4 is formed in the rear body, and this rear opening 4 is openably and closably closed by the rear gate 2, and the rear opening 4 is provided with a rear gate at the peripheral edge of the rear gate 2 when the rear gate 2 is closed. A weather strip 5 is attached to the inner surface of the peripheral edge of the rear body 2, and the weather strip 5 located below the rear opening 4 of the rear body is connected to the joint 7a of the rear end outer 6a and the rear end inner 6b. 7b, a notch 21 for draining water is provided in a part of the joint part 7b of the rear end inner 6b with the rear end outer 6a, as shown in FIG. A guide member 22 is provided for discharging rainwater, etc. that has flowed into the inner surface of the rear end outer 6a through the portion 21 to the outside.
The upper part of the guide member 22 is fixed to the inner surface of the rear end inner 6b, and the lamp housing 26 of the rear lamp 3 is formed in the lower part of the guide member 22, so that a drainage channel bent in the vertical direction is formed between the guide member 22 and the rear lamp 3. was formed. in this case,
The rear end outer 6a is a first outer panel 24 above the opening 23 for mounting the rear lamp 3.
and a lower second outer panel 25. A lamp housing 26 surrounding the mounting portion 3a of the rear lamp 3 is integrally formed on the upper part of the second outer panel 25. Furthermore, the upper end of the lamp housing 26 is joined to the inner surface of the rear end inner 6b, and the second outer panel 25 forms the guide member 22. Further, a groove-shaped bead portion 27 as shown in FIG. 7 is formed at the upper end portion of the second outer panel 25 at a portion facing the notch portion 21 of the rear end inner 6b. Rainwater, etc. runoff from the roof is smoothly guided to the outside. Note that the rear end inner 6b
The lower end of the lamp housing 26 is joined to the rear end of the lamp housing 26, and a bag-like structure 28 is formed between the rear end inner 6b and the lamp housing 26, increasing the strength of the vicinity of the mounting part of the rear lamp 3. It's becoming like that.

Therefore, in the case of the above structure, a notch 21 for draining water is provided in a part of the joint 7b of the rear end inner 6b with the rear end outer 6a, and the rear end outer 6a is connected to the rear end outer 6a through this notch 21. Since a guide member 22 is provided that guides rainwater etc. flowing out on the inner surface side of the first outer panel 24 to the outside side via between the rear lamp 3 and the lamp housing 26, it is possible to prevent rainwater etc. from forming due to poor adhesion of the weather strip 5. 5. Remove rainwater that has entered the inside of the vehicle.
As shown by the solid line arrow in the figure, it can be reliably discharged to the outside. Furthermore, rear end outer 6
A notch is not provided in the joint 7a of the first outer panel 24 of the first outer panel 24 with the rear end inner 6b, and the weather strip 5 is tightly attached to the entire outer surface of the joint 7a. This prevents rainwater from flowing back into the cabin from the outside,
It is also possible to reliably prevent mud and exhaust gas kicked up by the tires from flowing into the interior of the vehicle. Further, while the upper part of the guide member 22 is fixed to the inner surface of the rear end inner 6b, the lamp housing 26 of the rear lamp 3 is formed in the lower part of the guide member 22, and the lamp housing 26 of the rear lamp 3 is formed between the guide member 22 and the rear lamp 3 in the vertical direction. Since a bent drainage channel is formed, rainwater flowing in through the notch 21 can be reliably discharged to the outside of the vehicle, thereby preventing problems such as rainwater accumulating inside the rear end panel and causing rust. I can do it. Furthermore, since the drainage channel is bent in the vertical direction, rainwater splashed by the tires and water from washing the car are effectively prevented from reaching the notch 21 and entering the vehicle interior. be able to. In this case, the drainage channel is particularly connected to the guide member 2 forming the lamp housing 26 of the rear lamp.
2 and the rear lamp 3, it is possible to easily form a structure bent in the vertical direction depending on the back shape of the rear lamp 3, etc., and to prevent backflow of rainwater etc. with an extremely simple structure. I can do it.

It should be noted that this invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the gist of this invention.

As explained above, according to this invention, a notch for draining water is formed in a part of the joint between the rear end inner and the rear end outer, which forms the rear body below the rear opening that is opened and closed by the rear gate on the rear of the vehicle body. In addition to providing a guide member for discharging rainwater, etc. that have flowed into the inner surface of the rear end outer through this notch to the outside, it is possible that rainwater, etc. that has flowed into the inner surface of the rear end outer through this notch will be discharged to the outside. Infiltrated rainwater and the like can be reliably discharged to the outside, and it is also possible to prevent backflow of rainwater and the like from the outside to the interior of the vehicle, and to prevent exhaust gas and the like from flowing into the interior of the vehicle. Furthermore, while the upper part of the guide member is fixed to the inner surface of the rear end inner, the lamp housing of the rear lamp is formed in the lower part of this guide member, and a drainage channel that is bent in the vertical direction is formed between the guide member and the rear lamp. Therefore, rainwater flowing in from the notch can be reliably drained out of the vehicle, preventing problems such as rainwater accumulating inside the rear end panel and causing rust, and the drainage channel is connected to the top and bottom. Since it is bent with respect to the direction, it is possible to effectively prevent rainwater splashed up by the tires and water from washing the car from reaching the notch and entering the vehicle interior. In addition, it is possible to easily form a configuration bent in the vertical direction depending on the rear shape of the rear lamp, etc., so it is possible to prevent backflow of rainwater etc. with an extremely simple configuration, which is a rational and practical effect. to play.
