Abstract

A tailgate panel assembly for a vehicle includes an outer panel and an inner panel. The outer panel and the inner panel are directly joined to each other at an outer side with respect to a widthwise direction of the vehicle. An extended panel is joined to the inner panel and to the outer panel at an inner side with respect to the widthwise direction of the vehicle, thereby forming a closed cross-section.

First claim

What is claimed is:

1. A tailgate panel assembly for a vehicle, the tailgate panel assembly comprising:
an outer panel;
an inner panel that is located farther from a glass section of the tailgate than the outer panel, wherein the outer panel and the inner panel are directly joined to each other at an outer side with respect to a widthwise direction of the vehicle; and
an extended panel joined to the inner panel and to the outer panel at an inner side with respect to the widthwise direction of the vehicle, thereby forming a single closed cross-section, wherein a portion at which the inner panel and the extended panel are joined is positioned within a width of the single closed cross-section composed of the outer panel, the inner panel and the extended panel.

2. The tailgate panel assembly of claim 1 , wherein a portion at which the outer panel and the extended panel are joined is positioned within a width of the closed cross-section composed of the outer panel, the inner panel and the extended panel.

3. The tailgate panel assembly of claim 2 , wherein the extended panel is formed to allow an end portion thereof joined to the outer panel to be stepwisely bent towards the inner side of the width of the closed cross-section composed of the outer panel, the inner panel and the extended panel.

4. The tailgate panel assembly of claim 1 , wherein the inner panel and the extended panel are joined to each other by a structural adhesive.

5. The tailgate panel assembly of claim 4 , wherein the inner panel and the extended panel are joined to each other by a fastener.

6. The tailgate panel assembly of claim 5 , wherein the fastener comprises a fastening bolt and a fastening nut.

7. The tailgate panel assembly of claim 5 , wherein the inner panel and the extended panel are provisionally fastened by the fastener after applying the structural adhesive, and are joined to each other by curing the structural adhesive.

8. The tailgate panel assembly of claim 1 , wherein, in the closed cross-section composed of the outer panel, the inner panel and the extended panel, a distance from the center of gravity of the closed cross-section to an outer wall of the closed cross-section is formed to be greater than a distance from the center of gravity of the closed cross-section to an inner side wall of the closed cross-section.

9. The tailgate panel assembly of claim 1 , wherein, in the closed cross-section composed of the outer panel, the inner panel and the extended panel, a distance from the center of gravity of the closed cross-section to a lower wall of the closed cross-section is formed to be greater than a distance from the center of gravity of the closed cross-section to an upper wall of the closed cross-section.

10. The tailgate panel assembly of claim 1 , wherein the tailgate glass is formed at a side structure of a portion of the closed cross-section.

11. The tailgate panel assembly of claim 1 , wherein paint applied along a periphery of the tailgate glass has a width smaller than a width of the closed cross-section composed of the outer panel, the inner panel and the extended panel.

12. The tailgate panel assembly of claim 1 , further comprising a wiring installed on a stepped portion of the extended panel.

13. The tailgate panel assembly of claim 12 , further comprising a wiring guide restricting the wiring to be located on a bent portion of the extended panel, the wiring guide being fastened to the extended panel.

14. A tailgate panel assembly for a vehicle, the tailgate panel assembly comprising:
an outer panel;
an inner panel, wherein the outer panel and the inner panel are joined by a fastener or an adhesive, the outer panel and the inner panel joined to each other at an outer side with respect to a widthwise direction of the vehicle;
an extended panel joined to the inner panel and to the outer panel at an inner side with respect to the widthwise direction of the vehicle thereby forming a closed cross-section, wherein the extended panel includes a stepped portion between the outer panel and the inner Panel, the stepped portion being spaced from both the outer panel and the inner panel;
a wiring installed on the stepped portion of the extended panel; and
a wiring guide attached to the extended panel to restrict the wiring to be located on the stepped portion of the extended panel.

15. The tailgate panel assembly of claim 14 , wherein the outer panel and the inner panel are joined by both the fastener and the adhesive.

16. The tailgate panel assembly of claim 14 , wherein, in the closed cross-section composed of the outer panel, the inner panel and the extended panel, a distance from the center of gravity of the closed cross-section to an outer wall of the closed cross-section is formed to be greater than a distance from the center of gravity of the closed cross-section to an inner side wall of the closed cross-section.

17. The tailgate panel assembly of claim 14 , wherein, in the closed cross-section composed of the outer panel, the inner panel and the extended panel, a distance from the center of gravity of the closed cross-section to a lower wall of the closed cross-section is formed to be greater than a distance from the center of gravity of the closed cross-section to an upper wall of the closed cross-section.

18. The tailgate panel assembly of claim 14 , wherein the extended panel includes a first end contacting the outer panel but not the inner panel and a second end contacting the inner panel but not the outer panel;
wherein the extended panel includes first, second and third segments between the first end and the second end, the first segment contacting the first end and the third segment contacting the second end;
wherein the first, second and third segments are each spaced from both the inner panel and the outer panel;
wherein the first segment extends away from the outer panel, the second segment is arranged at an angle relative to the first segment and extends away from the first segment, and the third segment is arranged at an angle relative to the second segment and extends away from the second segment; and
wherein the stepped portion is created by the first and second segments.
