Description

[Detailed description of the invention] "Field of industrial application" This invention relates to an automobile back door mounting device that improves the operability of opening and closing the back door, as well as improving work efficiency and reducing weight during assembly. be.

``Prior Art'' Some automobiles have a resin cover that covers the upper part of the vehicle body at the rear of the driver's cabin with a resin cover separate from the vehicle body. This type of car uses the body behind the driver's cab as a luggage compartment or passenger seat, and the cover can be removed if necessary, but when used in Japan where there is a lot of rain and dust, the cover I often leave it attached. For this reason, it is convenient to integrate the door panel at the rear of the cover with the rear gate at the rear of the vehicle body.

``Problem that the invention aims to solve'' In the above-mentioned types of cars, the rear of the car body is perpendicular to the road surface, but the rear of the cover has a shape in which the top is slightly slanted forward relative to the bottom. Because of design and other reasons, it is common for the door panel on the cover side to be attached to the rear gate on the vehicle body side to form a back door, and if a hinge is also provided on the door panel side, this shape will change. Since the axis of the hinge must be provided on the same line as the axis of the rear gate hinge, the hinge on the cover side will protrude significantly rearward. In order to solve this problem, the door panel of the cover could be pivoted with a hinge at the top, and the door panel could be opened vertically while the rear gate opens sideways, but if you do this, rainwater will leak out from the gap between the rear gate and the door panel. There is a risk of infiltration.

This invention solves these problems and provides an automobile back door mounting device in which the door panel is removably mounted on the rear gate at the rear of the vehicle body, and the door panel is not provided with a hinge, but the door panel can be rotated horizontally together with the rear gate. The purpose is to

``Means for Solving the Problems'' The automobile back door mounting device of this invention has a horizontal upper edge and is used in automobiles in which the upper part of the vehicle body at the rear of the driver's cab is covered with a resin cover separate from the vehicle body. A rear gate made of a metal plate that is attached to the rear of the vehicle body by a hinge and rotates horizontally to open and close the rear surface of the vehicle body, and a plate that is attached from the horizontal upper edge of the rear gate to the upper rear surface of the rear gate. a seal rubber having a shape, a bifurcated part sandwiching the upper part of the rear gate with the seal rubber interposed between the lower parts and connected to the upper part of the rear gate with a bolt, and a forked part formed inside the forked part and abutting on the upper surface of the seal rubber. The present invention is characterized by comprising a resin door panel having ribs and rotating horizontally together with the rear gate to open and close the rear surface of the cover.

``Function'' If the configuration is as described above, the rear gate and the door panel attached to the rear gate will be integrated to form a back door.
This eliminates the need for hinges on the door panel, improving operability and water resistance.

``Embodiment'' Next, an embodiment of this invention will be explained with reference to the drawings. In FIG. It is covered with a cover 4 manufactured by Manufacturer. A rear gate 6 is provided at the rear of the vehicle body 3 so as to be opened and closed in a horizontal plane by means of a hinge 5. A door panel 7 is provided on the top of the rear gate 6 so as to open and close the rear part of the cover 4, and is attached to the rear gate 6 by a structure described later. Reference numeral 8 denotes a spare tire, which is attached to the rear gate 6 by a bolt (not shown) that projects rearward.

FIG. 2 shows a cross section taken along the - line in FIG. 1, and FIG. 3 shows the door panel 7 viewed from the inside of the vehicle. The door panel 7 is made of resin, and its lower part is bifurcated into a bifurcated portion 9 at the front and rear.

As shown in FIG. 2, the rear gate 6 has a horizontal upper edge formed by bending and joining the upper parts of an inner panel 10 and an outer panel 11 made of metal plates.
A plate-shaped seal rubber 16 is attached extending from the horizontal upper surface of the rear gate 6 to the upper rear surface of the rear gate 6.

The bifurcated portion 9 of the door panel 7 mentioned above sandwiches the upper part of the rear gate 6 with a seal rubber 16 interposed therebetween.
It is connected to the upper part of the rear gate 6 with bolts 12 and 13 and nuts 14 and 15. Nats 14, 15
is preferably fixed to the inner surfaces of the inner panel 10 and outer panel 11 by welding.

When the door panel 7 is connected to the rear gate 6 in this way, the vertical portion of the seal rubber 16 is sandwiched between the upper rear surface of the outer panel 11 and the rear side of the bifurcated portion 9, and the rib 17 of the door panel 7 is also placed on the upper surface of the seal rubber 16. They are starting to touch each other. A plurality of ribs 17 are formed inside and above the bifurcated portion 9 in the front-rear direction, and are provided at appropriate intervals as shown in FIG.

As shown in FIG. 2, a back door glass 19 is attached to the door panel 7 via a weather strip 18. The upper part of the door panel 7 is in contact with the cover 4 via a weather strip 20, as shown in FIG. This structure is similar to the side portions of the door panel 7.

The back door mounting device configured in this way is
Since the door panel 7 is integrated with the rear gate 6 to form a back door, there is no need to provide a hinge between the door panel 7 and the cover 4. Since the door panel 7 is made of resin and is lightweight, no burden is placed on the rear gate 6 and the hinge 5 that supports the rear gate 6 on the vehicle body 3. Further, by loosening and removing the bolts 12 and 13, the door panel 7 can be removed from the upper part of the rear gate 6.

``Effect of the invention'' As explained above, this invention
Since the door panel 7 is connected to the upper part of the rear gate 6 with bolts 12 and 13, the door panel 7 can be easily installed and removed, and in the connected state, the door panel 7 will not come off from the rear gate 6 due to vibration or the like. In addition, the lower part of the door panel 7 is a bifurcated part 9 that is connected to the rear gate 6.
Since the upper part of the rib 17 is sandwiched between the ribs 17, it is easy to position the door panel 7 on the upper part of the rear gate 6, and it is possible to hold it stably.
This makes it possible to ensure the rigidity of the bifurcated portion 9.

In addition, since the door panel 7 is made of resin and is lightweight,
Even without providing a hinge on the door panel, the strength during rotation can be maintained by the hinge 5 supporting the rear gate 6 made of a metal plate.

Furthermore, the seal rubber plate 16 attached from the horizontal upper edge of the rear gate 6 to the upper rear surface of the rear gate 6 can improve the watertightness between the rear gate 6 and the door panel 7.
