Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wing door provided on a wing body of a vehicle, and more particularly, to a wing door panel structure which can reduce the cost and make it more visible.

[0002]

2. Description of the Related Art Truck vehicles equipped with wing doors are excellent in cargo handling for loading and unloading luggage because the sides of the body can be fully opened.

FIG. 7 is a perspective view showing the appearance of a wing body 9 to which a conventionally known wing door 1 is mounted.

The wing door 1 is provided on the left and right of the upper part of the wing body 9, and as shown by the dotted line, when opening, it rotates upward about the upper central part, and the panel part 3,
The frame unit 2 is provided around the panel unit 3.

[0005]

However, the conventional wing door 1 has the following problems.

As described above, the wing door 1 can fully open the side surface of the body and is extremely excellent in cargo handling for loading and unloading luggage. However, when opened, the wing door 1 provides safety and smooth opening. In order to obtain it, it needs to have sufficient strength as a whole so as not to bend or deform.

Therefore, the structure of the wing door 1 requires a large number of reinforcing frames for the panel portion 3 in addition to the frame 2.

Therefore, the wing door 2 has a complicated structure with a heavy panel portion 3, which is expensive.

Further, a frame or a reinforcing plate is provided at a corner portion between the upper surface and the side surface of the panel portion 3, so that the external appearance is not so smart.

The present invention has been made in view of the above, and an object of the present invention is to provide a wing door panel structure having a simple structure that is lightweight and easy to see.

[0011]

A panel structure of a wing door according to the present invention is formed of a resin having a ladder-shaped cross section formed by an upper exterior panel, a lower interior panel, and a plurality of cross panels, and a corner portion bent at a right angle. And a side panel part to which a foam material is joined between the side exterior panel and the side interior panel and which is attached to the lower end of the resin upper panel part.

The upper panel made of resin is transparent or translucent.

A foam material is joined between the upper exterior panel and the upper interior panel, and a foam material is joined between the side exterior panel and the side interior panel, the upper panel portion having a corner bent at a right angle. A side panel attached to a lower end of the upper panel; and a corner interior frame formed in a ladder shape with a curved cross section is provided in the corner.

Further, a foam material having a curved cross section is provided in the corner portion instead of the corner interior frame.

The intermediate frame 25 is provided between the upper panel portion 40 and the side panel portion 50, and is attached mainly for reinforcement when the wing door 10 is relatively large.

FIG. 2 is a perspective view of the front side frame 21 and the panel section 30.

The panel section 30 comprises an upper panel section 40 and a side panel section 50 and is mounted on the front side frame section 21. An intermediate frame 25 (see FIG. 1) is provided between the upper panel section 40 and the side panel section 50. ) Is attached.

FIG. 3 shows a panel section 3 indicated by an arrow AA in FIG.
0 shows a sectional view.

The upper panel section 40 of the panel section 30 is formed of resin, and includes an upper exterior panel 41 and an upper exterior panel 4.
1 and a plurality of transverse panels 43 provided between the upper exterior panel 41 and the upper interior panel 42 to form a ladder-shaped cross section. The section is bent and formed in an L-shape.

The side panel 50 of the panel 30
In this example, a foam material 53 is joined between a side exterior panel 51 made of an aluminum material and a side interior panel 52 made of an aluminum material.

An upper end frame 23 is attached to the upper end of the upper panel 40, and
An intermediate frame 25 is attached between the side panel 50 and the lower panel 24, and a lower end frame 24 is attached to a lower end of the side panel 50. The rubber portion 26 is a cushioning material when the wing door 10 opens and closes.

FIG. 4 is a sectional view of a corner portion 40C of the upper panel portion 40 shown in FIG.

As shown by an arrow P, the corner portion 40C has a cross corner panel 43C.
The upper exterior corner panel 41C is also heated as a whole, and is entirely bent inward, so that it can have sufficient rigidity.

The upper panel section 40 can be made transparent or translucent depending on the resin used, and can illuminate the inside of the wing body 9 (see FIG. 7). It can be easily arranged and confirmed.

As described above, the upper panel section 40
The cross section is formed in a ladder shape by the upper exterior panel 41, the upper interior panel 42, and the plurality of transverse panels 43, so that sufficient strength can be obtained. It is cheap.

Further, since the upper panel section 40 is integrally formed in an L-shaped cross section, particularly, the corner section 40C
The surface can be made to look good without any irregularities.

The side panel portion 50 is formed by joining a foam material 53 between a side exterior panel 51 and a side interior panel 52 made of aluminum material, and can have a simple structure and high rigidity.

Therefore, the panel section 30 is
It is composed of an upper panel part 40 made of resin and a side panel part 50 made of aluminum formed with C. The overall structure is simple, has sufficient strength, can be made lightweight and inexpensive, and has a good looking look. It can be.

FIG. 5 is a sectional view of a panel section 60 according to another embodiment of the present invention.

The panel section 60 includes an upper panel section 70 made of aluminum and a side panel section 50 also made of aluminum.

The upper panel 70 includes an upper exterior panel 71.
