Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an assembly structure of a rear end panel in a hatchback vehicle or the like.

<Prior Art> Generally, as shown in FIG. 5, a hatchback vehicle has a large opening 3 opened and closed by a tailgate 2 at a rear portion of a body 1, and therefore, a rear end panel defining the opening. 4 and the like are required to have high rigidity against torsional load.

In the conventional rear end panel 4, as shown in FIGS. 6 and 7, the eaves-shaped plate 6 is bent rearward from the upper end of the first substrate 5 excluding the left and right parts, and the tip end of the eaves-shaped plate 6 is bent. A rear end panel inner 8 integrally formed with an upward flange 7 and notches 10 on both left and right sides of a second substrate 9 facing the first substrate 5 and the upper end of the second substrate 9 is moved forward. Rear end panel outer 12 bent plate 11
Both panels 8 and 12 are provided by inserting the spot gun 13 into the notch 10 and welding the mating surface of the eaves-shaped plate 6 and the upper plate 11 as shown in FIG. Was assembled.

<Problems to be Solved by the Invention> However, in the conventional assembling structure of the rear end panel 4 as described above, the rear end panel outer 12 has the notches 10 for inserting the spot gun in both right and left portions. Therefore, the left and right parts of the rear end panel 4 do not have a closed cross-section structure. Therefore, in order to provide the rear end panel 4 with sufficiently high rigidity, the plate thickness of both panels 8 and 12 described above must be increased. There was a problem that it had to be done.

Therefore, an object of the present invention is to provide a rear end panel assembling structure capable of thinning the panel while maintaining a sufficiently high rigidity.

<Means for Solving the Problems> In order to achieve the above object, the present invention is directed to an upwardly directed first joint flange portion extending in the vehicle width direction and curved left and right ends thereof, and left and right sides of the first joint flange portion. A second joint flange portion that is continuously connected to both ends and extends by bending forward, an eaves plate bent forward from a lower portion of the first joint flange portion, and a first bent downward from a front end of the eaves plate. Substrate, a lower plate bent backward from the lower end of the first substrate,
And a rear end panel inner having a downward flange portion bent downward from a rear end of the lower plate, and an upward third connecting to the first joint flange portion extending in the vehicle width direction and curved left and right ends thereof. A rear end panel outer having a joining flange portion, a bent plate extending from the lower end of the third joining flange portion by bending backward, and a second substrate extending downward from the rear end of the bent plate and having the downward flange portion joined thereto. And the tip ends of the left and right ends of the first joint flange portion traverse the eaves-shaped plate forward, and protrude forward from the front end of the eaves-shaped plate by the width dimension of the second joint flange portion. The formed lower portion of the protruding first joining flange portion is connected to the second joining flange portion, and an outward flange portion is formed at the vehicle width direction end portion of the first substrate, The outward flange portion and the downward flange portion on the second substrate in al, the second joining flange portions and characterized by being respectively coupled to the lower surface the bent plate.

<Operation> According to the configuration described above, a closed cross-section structure is obtained over the entire length of the rear end panel, and rigidity is enhanced.

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

As shown in FIGS. 1 and 2, the rear end panel 4 has a rear end panel inner 20 and a rear end panel outer 21 extending in the vehicle width direction.

As shown in FIG. 3, the rear end panel inner 20 includes a first substrate 22 in which both left and right parts are slightly inclined rearward, and a lower plate 23 bent backward from the lower end of the first substrate 22. A downward flange portion 24 and an outward flange portion 31 which are continuously formed at the tip of the lower plate 23 and the left and right ends of the first substrate 22.
An eaves-like plate 25 bent rearward from the upper end of the first substrate 22 excluding both left and right parts, and a first joint flange part 26 formed upward at the tip of the eaves-like plate 25, The first joint flange portion 26 has a second joint flange portion 27 formed on both left and right portions of the upper end of the first substrate 22 by being continuously turned forward from both left and right ends, and these are formed by using a sheet metal or the like. Pressed.

On the other hand, in the rear end panel outer 21, the lower half portion is slightly recessed forward, and the above-mentioned downward flange portion 24 and outward flange portion 31 are joined to the upper half portion by spot welding.
The base plate 28 and the second base plate 28 are bent forward from the upper end of the second base plate 28, and the second joint flange portions 27 described above are jointed to the left and right portions thereof from below by spot welding to form a rear end panel end portion into a bag structure. It has a bent plate 29 and a third bonded flange part 30 which is formed at the tip of the bent plate 29 upward and is joined to the above-mentioned first bonded flange part 26 by spot welding, and these are made of sheet metal or the like. Are pressed.

Reinforcing ribs and holes for mounting various parts are appropriately formed on both the panels 20 and 21.

As described above, in this embodiment, the two panels 20 and 21 are basically assembled by joining the outward flanges. Spot welding can be easily performed from the outside of both panels 20 and 21 without forming notches or the like. As a result, in this embodiment, not only in the middle portion of the rear end panel 4 in the vehicle width direction but also in both left and right portions, as shown in FIG. 4, a closed sectional structure is obtained and rigidity is increased. The thickness can be reduced to 20,21.

<Advantages of Device> As described above, according to the present invention, the rear end panel inner and the rear end panel outer can be joined without forming a notch or the like for inserting the spot gun. A closed cross-section structure is obtained over the entire length of the panel, and thus the panel can be made thin while maintaining sufficiently high rigidity.
