Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a back door structure for an automobile.

(Prior Art) Some automobiles include a back door that opens and closes in the vertical direction at the rear of the vehicle body, as represented by a coupe type automobile.

The window provided on the back door is set to be inclined so that it becomes lower toward the rear. However, the visibility behind the vehicle body from the passenger compartment through the window of the back door is not always good.

From this point of view, as shown in Japanese Utility Model Application Laid-Open No. 53-30624, the inclined window is used as a first window, and a second window extending downward from the vicinity of the rear end of the first window is further provided. It is proposed that the rear side of the vehicle body can be visually recognized from the passenger compartment through the second window. That is, by providing the second window, it is possible to improve the situation where the lower end of the back door hinders the rear view. Then, in the frame of the back door, the rear end of the first window and the upper end of the second window are provided with respect to the lateral frame extending in the vehicle width direction at the boundary between the first window and the second window. Is fixed.

The fixing of the upper end of the second window to the horizontal frame is described in the above publication in which the joint flange portion of the outer panel and the inner panel forming the horizontal frame is extended downward and slightly lower than the outer surface of the outer panel. The upper end of the second window is seated on the outer surface of the joint flange so as to be fixed. As a result, the outer panel and the second window are substantially flush with each other so that the appearance is good.

(Problems to be solved by the invention) However, even the one described in the above publication is still not sufficiently satisfactory from the viewpoint of securing a rear view. Explaining this point in detail, the horizontal frame serves as a boundary portion between the horizontal surface and the vertical surface at the rear end of the vehicle body and occupies a large weight in the vehicle body design. The horizontal frame will have to be positioned at a considerably high position. This increases the sectional height of the horizontal frame, which is disadvantageous in terms of securing the rear view.

(Object of the Invention) Therefore, an object of the present invention is to extend the first window inclined and the second window extending downward from the vicinity of the rear end of the first window.
(EN) A back door structure for a vehicle, in which a rear view can be more sufficiently secured in a back door provided with a window.

(Structure and operation of device) In order to achieve the above-mentioned object, the present invention has the following structure. That is, a back door structure for an automobile, which is provided at a rear portion of a vehicle body so as to be openable and closable in a vertical direction, and includes a first window extending obliquely in a front-rear direction and a second window extending below a rear end portion of the first window. At a boundary portion between the first window and the second window, a horizontal frame of the back door, which extends in the vehicle width direction and fixes the rear end of the first window and the upper end of the second window, is positioned. A garnish is provided to cover an outer surface of the lateral frame, and the garnish covers a fixed portion of the second window with respect to the lateral frame.

As described above, according to the present invention, the outer surface of the lateral frame is covered with the garnish, so that the requirement for the vehicle body design at the boundary portion between the first window and the second window can be substantially left to the garnish. This means that the structure of the horizontal frame only needs to secure the required strength, and the cross section thereof can be made small, and particularly the vertical cross section can be made small. In addition to this, since the garnish covers the fixed portion between the upper end of the second window and the lateral frame, even if the fixed portion has a structure that makes it a little unattractive, there is no particular bearing. This leads to that the upper end of the second window can be positioned as close as possible to the upper end of the horizontal frame, and the second frame can be fixed even when the vertical cross section of the horizontal frame is reduced.

(Effects of the Invention) As described above, according to the present invention, it is possible to further reduce the degree of hindrance to the rear view by the lateral frame, and it is possible to more sufficiently secure the rear view. Further, since the lateral frame is not restricted by the viewpoint of the vehicle body design, the manufacturing of the entire back door becomes easy.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

First, the entire back door will be described with reference to FIGS. 1 and 2.

The automobile B has a front seat 1 and a rear seat 2, and the rear of the rear seat 2 is a trunk room 3.

The trunk room 3 can be inserted into the outside of the vehicle body through an opening 4 formed in the rear portion of the vehicle body, and the opening 4 is opened and closed by a back door 10. That is, the front end portion of the back door 10 is attached to the roof panel 5 via a hinge (not shown), and by moving the rear end portion of the back door 10 up and down, the solid line in FIG. The closed position shown and the open position shown by the one-dot chain line in FIG. 1 can be selectively taken. The back door 10 has a first window 11 and a second window 12, as will be described later.
Has two windows.

As shown in FIG. 3, the frame 13 of the back door 10 is basically constituted by an outer panel 14 and an inner panel 15 as a closed cross section structure. The frame 13 includes three horizontal frames, first to third, which extend in the vehicle width direction.
With 13a to 13c, the first horizontal frame 13a is located at the front, the second horizontal frame 13b is located behind the first horizontal frame 13a, and the third horizontal frame 13c is located at the second horizontal frame 13b. It is located just below.

The side edges of the first horizontal frame 13a and the second horizontal frame 13b have a pair of left and right connecting frames 13 extending in the front-rear direction.
The four windows 13a and 13b are connected to each other by d, and the two windows 13d hold the peripheral edge of the first window 11. In other words, the first opening of the back door 10 covered by the first window 11 is defined by the four members 13a, 13b and the two 13d. Of course, the first window 11 is inclined so that it becomes lower from the front to the rear.

The side edges of the second horizontal frame 13b and the third horizontal frame 13c have a pair of left and right connecting frames 13 extending vertically.
These four members 13b, 13c and two 13e are connected to each other by e, and the peripheral portion of the second window 12 is held. In other words, the second opening of the back door 10 covered by the second window 12 is defined by the four members 13b, 13c and the two 13e. Of course, the second window 12 extends vertically.

The structure near the boundary between the first window 11 and the second window 12 will be described with reference to FIG.

First, the rear end of the first window is fixed to the second horizontal frame 13b located near the boundary between the first window 11 and the second window 12 using the adhesive A1. The upper end of the second window 12 is fixed to the second horizontal frame 13b. When fixing the second window 12, in the embodiment, in addition to the adhesive agent A2, the bolt 16 which is previously fixed to the front surface of the upper end portion of the second window 12 by an adhesive agent or the like.
It is also performed by using nut 17 and. That is,
With the bolt 16 penetrated by the joint flange portion 18 extending in the vertical direction in the second horizontal frame 13b, the nut
This is done by screwing 17 onto the contact bolt 16. The upper end of the second window 12 is located near the upper end of the second horizontal frame 13b in the fixed state.

The outer surface of the second horizontal frame 13b is covered with the garnish 19. The garnish 19 is formed of, for example, plastic or the like so as to match the shape required from the viewpoint of vehicle body design. More specifically,
The front end portion 19a of the garnish 19 is positioned on the rear end portion of the first window 11 so as to overlap the rear end portion of the first window 11 slightly. Further, the garnish 19 smoothly extends rearward from the front end portion 19a so as to match a desired vehicle body design, and then gently curves downward and extends downward. Then, the rear end portion of the garnish 19, that is, the lower end portion 19b,
The position is slightly lower than the bolt 16, that is, the minimum required position so as to cover the fixed portion between the second horizontal frame 13b and the second window 12. In addition, garnish 19
Is fixed to the second horizontal frame 13b using an adhesive A3.

Incidentally, reference numerals 20 and 21 in FIG. 3 are trim members.
