Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to the structure of an opening/closing body such as a trunk lid or back door that covers an opening formed in the rear body of an automobile.

(Prior Art) A trunk lid back door, etc. that covers the opening of the vehicle body at the rear of an automobile is usually composed of an outer panel forming the outer surface and an inner panel forming the inner surface in order to ensure a certain level of strength. Both panels are joined by welding or the like on the entire circumference. Japanese Utility Model Application Publication No. 59-53118 discloses a back door having such a structure.

(Problems to be Solved by the Invention) However, when the opening and closing body is constructed of both panels in this manner, the weight of the opening and closing body becomes large. Further, when attaching exterior parts such as a tail lamp and a license lamp to such an opening/closing body, a mounting portion must be formed on the outer panel itself. Since this attachment portion is formed by molding the outer panel into a predetermined shape, the layout of the exterior components is limited to the moldable range of the outer panel.

The present invention has been made in view of these points, and aims to provide an opening/closing body that is lightweight and allows for easy attachment of exterior parts to the opening/closing body.

(Means for Solving the Problems) The opening/closing body of an automobile according to the present invention includes a first plane portion extending from the front of the vehicle body to the rear of the vehicle body, and a first bent portion extending from the rear end of the first parallel portion toward the bottom of the vehicle body. a second plane part extending substantially parallel to the first plane part; and a second plane part extending substantially parallel to the first plane part; In the opening/closing body for an automobile, the auxiliary member extends substantially perpendicularly to the second bending portion, and has one end extending substantially perpendicularly to the second bending portion. It is connected to almost the tip of the first bent part, and the other end is connected to the second bent part, and a space is formed below the auxiliary member for attaching the exterior parts, and when the exterior parts are attached, the second bent part All parts extending downward from the first bent part of the outer panel are covered by the outer panel, and the distance between the first bent part and the second bent part is equal to the outer surface of the outer panel when the outer part is attached. is determined so that it lies substantially in the same plane as the outer surface of the exterior component.

(Example) Examples of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the present invention, in which the present invention is applied to a trunk lid.

As shown in FIGS. 1 and 2, the trunk lid 1 consists of a portion A consisting of an inner panel 3 and an outer panel 5 extending in the longitudinal direction of the vehicle body, and only the inner panel 3 extending from the rear end of this portion A toward the lower side of the vehicle body. It consists of a part B consisting of:

As shown in FIG. 4, the outer panel 5 has a flat portion 5a as a first flat portion extending from the front of the vehicle body to the rear of the vehicle body, and the rear side of this flat portion 5a is slightly inclined toward the bottom of the vehicle body. Plane part 5a
A curved portion 5 is formed as a first bent portion that curves downward from the rear end of the vehicle body and extends downward. On the other hand, the inner panel 3 has a U-shaped cross section that opens toward the outer panel 5 at the portion facing the front end and both side ends of the outer panel 5, and is closed by this U-shaped cross section and the outer panel. A cross section is formed. FIG. 3 shows a closed section extending from the left end of the vehicle body in the longitudinal direction, and shows the side end (flange) 3 of the inner panel 3.
a is held between the side ends 5c of the outer panel 5 which is bent inward, and both ends are joined by welding.

As shown in FIGS. 1 and 4, the inner panel 3 has a flat portion 3k as a second flat portion extending substantially parallel to the flat portion 5a of the outer panel 5. A vertical wall 3c extends as a bent portion. The vertical wall 3c is a curved portion 5b
and is substantially parallel to the curved portion 5c. Further, the vertical wall 3c of the inner panel 3 extends downward from the vehicle body longer than the curved portion 5b of the outer panel 5, forming a portion B consisting only of the inner panel 3. The lower end of this vertical wall 3c is bent toward the rear of the vehicle body at a substantially right angle, and the lower end of the vertical wall 3d
A flange 3e is formed by bending the lower wall 3d at a right angle toward the bottom of the vehicle body. Further, both ends of the vertical wall 3c are bent toward the rear of the vehicle body at a substantially right angle to form a side wall 3f, and the tip of the side wall 3f is further bent outward in the vehicle width direction at a substantially right angle to form a flange 3g. It is formed. The side wall 3f and flange 3g are connected to the lower wall 3d and flange 3e, respectively.

Here, as shown in FIG. 1, the length in the vehicle width direction of the portion B consisting only of the inner panel is narrower than the width of the outer panel 5. Therefore, the side wall 3f and the flange 3g of this portion B are bent outward in the vehicle width direction at the tip 5d of the curved portion of the outer panel 5, and are connected to the side wall 3h and flange 3a of the above-mentioned U-shaped cross section, respectively.

Next, part B consisting only of this inner panel
, a plate-shaped reinforcing member 7 extending in the vehicle width direction is attached between the side walls 3f, 3f.
That is, this reinforcing member 7 is arranged in parallel with the lower wall 3d near the tip 5d of the curved part of the outer panel 5, and its ends facing the longitudinal direction of the vehicle body are bent downward and upward at right angles, respectively. Flanges 7a and 7b are formed, of which flange 7a is joined to the vertical wall 3c. Further, both ends of the flange 7b protrude above the flange 3g of the side wall 3f and are joined to the flange 3g. On the other hand, the ends of the reinforcing member 7 in the vehicle width direction have flanges 7c and 7d bent toward the lower side of the vehicle body, respectively.
d is joined to both side walls 3f, 3f.

As described above, in the portion B consisting only of the inner panel, the inner panel and the reinforcing member form the recess 9 that opens toward the rear of the vehicle body.
This recess is used as an attachment part for the exterior parts.

That is, as shown in FIG. 1, a garnish 17 having a license plate seat 15 in the center where the tail lamp 11 and the license lamp 13 are attached is mounted in the recess 9. Flanges 17a are formed around the four peripheries of the garnish 17, and abut against flanges 3e, 3g, and 7b formed around the four peripheries of the recess 9, and these flanges are joined by bolts or the like. Furthermore, in this example, the garnish 1 attached to the recess 9
A molding 21 is attached between the upper end of the vehicle body 7 and the tip 5d of the rear panel. For this purpose, an attachment hole 23 for attaching a clip 21a of the molding 21 is formed at the tip 5d of the outer panel.

In addition, in the recess 9, a hole 3i made in the vertical wall 3c and a hole 7e made in the reinforcing member 7 are holes for pulling out lead wires of a tail lamp and a license lamp, respectively.

5 to 7 show other embodiments of the present invention. In this example, the arrangement of the reinforcing member in the recess 9 is changed. To explain in detail, in this example, the reinforcing member 3 has a U-shape as a whole.
1 is used. Both side walls 31 of this reinforcing member 31
a, 31b and the upper wall 31c have flanges 31d, 31e, 31f and 31g at the front and rear ends of the vehicle body.
31h and 31i are formed, among which flanges 31d, 31e and 31f on the front end side of the vehicle body are respectively joined to the vertical wall 3c. The flange 31i on the rear end side of the vehicle body of the upper wall 31c is joined to the outer panel tip 5d from the rear side of the vehicle body.
1a, 31b rear end side flanges 31g, 31 of the vehicle body
As shown in FIG. 7, h is the mounting surface of the exterior component, which is indicated by a dashed line. Also, both side walls 31a, 3
The flanges 31j and 31k at the lower end of the vehicle body 1b are respectively joined to the lower wall 3d of the inner panel. Furthermore, in this example, a portion of the outer panel tip 5d is extended to form a flange 3g formed on the side wall 3f of the inner panel and the side walls 31a, 31 of the reinforcing member.
Flanges 5e and 5f are formed between the flanges 31g and 31h formed in b, and these flanges 5e and 5f are also used as mounting surfaces for exterior parts.

The other configurations are the same as the example shown in FIG.

In each of the embodiments described above, the lower end side of the opening/closing body is formed only from the inner panel, but it can also be formed only from the outer panel.

(Effects of the invention) In the trunk lid constructed as described above, the lower end side of the opening/closing body is comprised of only one panel, so the weight of the trunk lid itself can be reduced. Furthermore, parts such as a tail lamp and a license lamp are attached to the outer surface of the vehicle body, which is made up of only one panel. Therefore, the layout of the exterior parts becomes easy. In addition, when the lower end side of the opening/closing body is composed of only the inner panel, parts can be attached using the space from the outer surface of the vehicle body of the inner panel to the inner surface of the outer panel. That is, when attaching each component, there is no need to partially mold the inner panel or the outer panel itself to form attachment portions for each component. As a result, each component can be freely arranged, and the outer panel itself can be easily molded.

Furthermore, since the outer surface of the bent portion is completely covered by the lamp, license plate, and other exterior parts, there is no need for improvement in precision, appearance, etc. in forming the outer surface of the bent portion. Further, since the outer surface of the exterior component and the outer panel are substantially flush with each other, this is preferable in terms of appearance and aerodynamic characteristics.

Although the present invention has been described in the case where it is applied to a trunk lid, the present invention is not limited to this. For example, it goes without saying that the present invention can also be applied to a back door of a vehicle having a hatchback type vehicle body.
