Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile door structure, and in particular to a door trim structure.

Conventionally, in the process of outfitting automobile doors, a door with a structure in which the peripheral edges of an outer panel and an inner panel are joined to each other is attached to the vehicle body, and the space inside the door is formed between the outer panel and the inner panel of the door. On the factory line, a worker inserts a door lock device, a wind regulator device, and other functional parts inside the door through an appropriate number of work holes drilled in the inner panel, and then They used their hands to individually install these functional parts inside the door, and then covered the surface of the inner panel with the door trim.

However, in order to maintain the rigidity of the door, these work holes cannot be made too large, and most of the functional parts must be installed on the inner panel side of the door interior space, making it difficult for workers to operate. The installation location becomes a blind spot, and the installation work must be done by hand, resulting in extremely poor work efficiency. Furthermore, it is difficult to automate the installation work because the work is diverse.

Therefore, as shown in FIG. 1, an opening 4 of various sizes is drilled in advance in the center of the inner panel 3 whose peripheral edge is joined to the outer panel 2 of the door 1. By closing the door 1 with the sub-panel 5 which is the third panel, the rigidity of the door 1 can be maintained. controller device 6, a door lock device 7, an electric actuator 8 for remotely controlling the door lock device 7, an inside handle 9, a check link device 10 for imparting an appropriate sense of resistance to the opening/closing operation of the door 1, and a speaker. The functional parts inside the door, such as No. 11, are installed integrally in advance, and in that state,
It is considered that by attaching the sub-panel 5 to the inner panel 3, the work of attaching functional parts can be significantly simplified.

In this case, the door trim 12, a grip handle 13, an armrest 14, a tray box 15, a locking/unlocking knob device 16, an escutcheon 17 for an inside handle, and a window regulator handle 1 are attached to the door trim 12.
8. Speaker cover 19 and step lamp 20
The indoor interior parts such as the above are also integrally attached to the sub-panel 5 in advance before the sub-panel 5 is attached to the inner panel 3.

Further, the door glass 21 is inserted into the door interior space through the opening 4 or, as in the conventional case, a slit 22 for raising and lowering the door glass formed at the upper part of the door 1.
After attaching the sub-panel 5 to the inner panel 3, the glass holder 2 is fixed to the door glass 21.
3 and the carrier plate 6a of the wind regulator device 6 are connected to each other using appropriate bolts 24a and nuts 24b.

The outside handle 25 is attached to the outer panel 2 before the sub-panel 5 is attached to the inner panel 3, but in some cases, the outside handle 25 is also attached to the sub-panel 5 side, and the sub-panel 5 is attached to the inner panel 3. When the outside handle 25 is attached to the door 1 from the opening (not shown) formed in the outer panel 2,
You can do whatever you want on the outside.

26 is a window frame erected above the door 1.

The present invention was made in relation to so-called pack doors that are assembled using such a method, and in particular, even after the door trim is attached to the inner panel, it is possible to easily adjust the functional parts inside the door from the outside. The object of the present invention is to provide a door structure for an automobile that allows for easy installation and final installation work.

That is, in the above-mentioned packed door, after inserting the door glass 21 into the door 1, the sub-panel 5 to which the window regulator device 6, door trim 12, etc. are integrally attached is inserted into the inner panel 3.
After that, the glass holder 23 of the door glass 21 and the carrier plate 6a of the window regulator device 6 are connected.
Opening 4 of inner panel 3 by door trim 12
It would be impossible to carry out this work if the area was completely blocked.

In addition, when attaching the sub-panel 5 to the inner panel 3, the upper part of the sub-panel 5 shares the set screw 27 for attaching the grip handle 13 etc. to the door trim 12, so that it looks good.
To avoid unsightly exposure of the screw heads on the trim surface,
However, when it comes to installing the lower part of the sub-panel 5, there is no suitable set screw that can be shared with the lower part of the door trim 12, allowing the screw head to be unsightly exposed on the surface of the door trim 12, or , sub panel 5 and door trim 1
It is necessary to first attach the sub-panel 5 to the inner panel 3, and then attach the door trim 12 from the outside. However, in that case, the advantage of improved workability of the packed door would be halved.

Therefore, even after the door trim is attached to the inner panel, the present invention makes it possible to easily perform the work of connecting the window regulator device and the door glass, the work of connecting the sub-panel and the inner panel, etc. After completing those tasks,
The object of the present invention is to provide an automobile door structure that can exhibit a beautiful appearance that is no different from conventional ones.
