Abstract

PURPOSE:To ensure a sufficient opening degree of back doors and to aim at commonly using a vehicle body panel, by forming cut-outs for evading vehicle body side rear combination lamps, in the side sections of the back doors, and by arranging the upper and lower hinges of the doors in the vicinity of right and left side edges of the vehicle body. CONSTITUTION:Right and left split back doors 1, 1 are formed such that they covers as whole the rear end section of a vehicle body 2, and the boundary between the back doors and the vehicle body 2 extends along the outside edge of the vehicle body 2. In the above-mentioned arrangement, cut-out sections 5 are formed in the right and left side sections of the back doors 1 in order to evade rear combination lamps 4 on the vehicle body 2 side, and the top edges of the back doors are slightly curved toward the roof side of the vehicle body 2. Further, a pair of hinges 7, 8 for rotatably supporting each back door 1 are secured to sections above and below the associated rear combination lamp 4 in the vicinity of the right and left outside edges of the vehicle body 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to the improvement of a back door structure for a so-called pan-type automobile, particularly a double-folding back door structure that opens on both the left and right sides.

BACKGROUND OF THE INVENTION The back doors of pan-type automobiles can be roughly divided into two types: flip-up type back doors that open upward and double-fold type back doors that open on both the left and right sides. Figure 4 shows a conventional double-folding back door structure, which is divided into left and right parts.RT and T back doors 11
．． 11, the edge 12 on the hinge side is formed into a substantially elongated shape when viewed from the rear of the vehicle body,
A pair of upper and lower hinges 15° 15 are fixedly installed along the inside of the rear combination lamp 14 buried on both sides of the rear end of the 41 body 13, and the hinges 15, 15 are constructed to be rotatable. It is supported. In other words, a T-shaped and approximately rectangular vehicle body opening is set, leaving a relatively wide aperture behind a part 16 of the roof above the rear combination lamp 14, and the back door 11 is attached here (for example, (See "Toyota Dyna New Model Book Commentary Homare"316'f1, published in August 2013).

However, in the above-mentioned conventional double-folding back door structure, the rear pillar part 16 and the rear connection run 7'14 have 4m'c of the back door as the center of the rear pillar. 11 opens, the door opening degree is limited to a relatively small range of 180 degrees or less, and there are problems in that the rear opening area is small compared to the rear area of the vehicle body. In contrast to the double-folding back door mentioned above, there is a flip-up back door.

A back door is formed in an L-shaped outer shape that substantially covers the rear end of the vehicle body, including the rear ys side plate of the rear villa part 16 fL.

(lr) Since the boundary between the back door and the vehicle body is set along the outer edge of the vehicle body, even for the same plate type, there are cases where a flip-up type back door structure is adopted and a case where a double-fold type back door structure is adopted.
``The structure of the rear part of the vehicle body is basically different depending on the case where it is adopted, and there is a problem that not only is it impossible to share the IL body panel, but the assembly process is also fJIi.

Is there a prescribed way to solve the problem with the above problems? In order to solve the problem, the double-door opening type back door structure for an automobile according to the present invention includes a rear combination lamp on the vehicle body side on the side of the back door that is divided into left and right parts and has a shape that covers the rear part of the vehicle body as a whole. Along with forming a notch to avoid! The present invention is characterized in that hinges are fixedly installed near the outer edge of the body and at the upper and lower parts of the rear combination lamp, respectively, and the left and right back doors are each rotatably supported through one hinge.

Function: The back door opens with a hinge centered near the outer edge of the body, and its opening degree is not restricted by the rear combination lamp or part of the door. The outer shape of the entire back door is the same as that of the flip-up back door.

5J! Example No. 1m is a perspective view of an automatic S-rear section showing a double-folding back door structure according to the present invention.

The back door 1.1, which is divided into left and right parts, is generally collapsed at the rear of the vehicle body 2, and is extended in the left and right width direction compared to conventional ones. A boundary 3 between the vehicle body 2 and the vehicle body 2 is located along the outer edge of the vehicle body 2.

There is a rectangular notch 5 on the left and right sides of the back door 1 to avoid the vehicle body 2@norya combination lamp 4.
is formed.9. Moreover, the upper edge 6 of the back door 1 slightly wraps around toward the roof side of the vehicle body 2. That is, the overall outer shape of this back door 1.1 is exactly the same as the outer shape of the back door in the flip-up type back door structure, and therefore the shape of the door opening of the vehicle body 2 is also the same as that of the back door in the flip-up type back door structure. The details of the gold wire are the same as the door structure.

- A pair of hinges 7.8, each of which rotatably supports the back door 1, are fixed to the upper and lower parts of the handler combination lamp 4 near the left and right outer edges of the IL body 2. In addition, the lower blade hinge 8 has an arm that is fixed to the back door 1 and is formed longer than the upper blade hinge 7. In this case, the upper half of the door opening has a slightly trapezoidal shape and is slightly inclined forward at 7JO, but the hinges 7 and 8 are placed at approximately the center height position and the lower end of the door opening, respectively. A line connecting the centers of the hinges of the HL body 2 and the HL body 2 protrudes somewhat from the rear end surface of the L body 2, and is substantially perpendicular to the HL body 2 when viewed from the rear and side.

Therefore, the back door 1 can be opened sufficiently wide without interfering with the rear villa part 9, etc.

Figure 2 shows the back door 1 opened approximately 18 degrees.

Figure 3 shows each metal in an approximately 270° open state.

Effects of the Invention As is clear from the above explanation, L'n? I% is added to the side of the backdoor, which is shaped like a full-length extension.

One side rear combination lamp? Notch to avoid? At the same time, an upper part and a lower part a are formed near the outer edge of one body.
Since the door is fixed in place, the door opening angle is sufficiently large compared to conventional ones.

The door opening area is also sufficiently large. Therefore, loading and unloading of luggage can be done easily. The structure of the rear extension of the main body can be basically the same as that of the flip-up back door, making it possible to share the body panels and simplify the assembly process. Furthermore, as a result of all the hinges being placed above and below the rear combination lamp, it is possible to ensure a relatively long span for both hinges, and it is also easy to ensure that the hinge centers are vertically connected in relation to the body shape.

For example, there are no problems such as the hinges protruding greatly and the door opening diagonally upward.
