DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door structure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 10 and 11, a door structure of this type is formed by an inner panel 1 and an outer panel 2 so that flange portions formed on the outer peripheral portions of the panels 1 and 2 are connected to each other. Door bag part 3 by joining
Is formed.

[0003] The inner panel 1 is formed with a plurality of openings 4 as mounting holes for disposing components in the door bag portion 3, and the openings 4 are formed in the inner panel 1.
In order to secure a predetermined rigidity of the door structure itself, it is formed as small as possible.

[0004] From the opening 4, for example, a glass elevating mechanism 7 to which the door glass 6 is not attached is sunk into the door pouch 3, and a mounting hole provided in a guide rail 8 constituting the glass elevating mechanism 7. The glass elevating mechanism 7 is mounted on the inner panel 1a by matching the mounting holes 8a with the mounting holes 1a on the inner panel 1 side and mounting the screws 8c and the like in the mounting holes 1a. In this case, the glass elevating mechanism 7 includes a glass mounting portion 8b slidably disposed in the guide rail 8, and a glass mounting portion 8b.
And a motor 10 for driving a wire 9 that slides the door glass 6. The rotation of the motor 10 is transmitted to the wire 9, whereby the glass mounting portion 8 b slides along the guide rail 8, thereby causing the door glass 6 to slide. Since the guide rail 8 and the motor 10 are connected by a wire 9, by bending the wire 9, the entire lifting mechanism 7 is moved from one of the working holes 4 to the door pocket. It can be sunk into the part 3.

Further, the motor 10 is attached to the inner panel 1 by screwing screws or the like into the attachment hole 10a of the motor 10 and the motor attachment hole 2a formed in the inner panel 1.

After the glass lifting mechanism 7 is mounted on the inner panel 1, the glass 6 is moved to the lower end side so that the glass 6 can be raised and lowered in the sash 12 attached so as to extend to the inside of the door bag portion 3. From the upper opening 5 of the door bag part 3
And the opening y in the lower end mounting portion 6a of the glass 6
Opening x in the mounting portion 8b formed on the guide rail 8
The glass 6 is mounted on the guide rail 8 by inserting a driver or the like from the through hole k and screwing the screw.

The mounting of the guide rail 8 is performed as shown in FIG.
As shown in FIG. 1, the upper and lower ends of the guide rails 8 are mounted so as to float on the inner panel via the rail brackets 11 so that the door glass 6 can be raised and lowered smoothly. The guide rail 8 follows the vertical movement of the curved door glass 6.
It can slide inside.

As described above, after the glass elevating mechanism 7 and the like are mounted in the door bag portion 3, the sealing screen 13 is attached to almost the entire inner panel 1 by the sealing screen 13 so as to close the working holes 4. Next, the door trim 14 is attached to the inner panel 1 by using a trim clip 14a or a partial screw.

[0009]

However, in the conventional automobile door structure device configured as described above, the plurality of working holes 4 provided in the inner panel 1 are provided with a door structure controlled by the inner panel 1. In view of the rigidity of the opening, it was not possible to form the opening as too large.

For this reason, the glass elevating mechanism 7 is attached to the inside of the inner panel 1 by an operator inserting one hand into the opening 4 and holding the glass elevating mechanism 7 with the other hand. The holes 1a and 8a are aligned so that screws are inserted and fixed using a motor tool. Not only is the insertion of the screws into the mounting holes 8a a blind operation, but also the lifting and lowering of the heavy glass with one hand. This is a very difficult task of holding the mechanism 7.

The guide lifting rail 8 and the motor 10
Since it is connected with the wire 9 by the wire 9, it is very inconvenient to arrange the glass elevating mechanism 7 in the door bag portion 3, and the mounting operation is in a considerably bad condition.

Further, since only a small working hole 4 is provided on the inner panel 1 in consideration of its rigidity, the inner panel 1 becomes considerably bulky and becomes a bottleneck in reducing the weight of the door structure for automobiles. Was.

When attaching the glass 6 to the guide rail 8, the operator holds the glass 6 with one hand, inserts the upper opening 5 of the door pouch 3, and uses the other hand to hold the lower end of the glass 6. Then, a screwdriver or the like was used to align the opening x of the glass mounting portion 8b with the opening y of the lower end mounting portion 6a of the door glass 6 by inserting a screwdriver into the through hole k and screwing it. This is an installation work, and it cannot be denied that the work is a blind work, which also impairs the workability.

Further, the guide rail 8 is mounted on the inner panel via the rail bracket 11, and is mounted so as to float on the inner panel, thereby substantially contributing to an increase in rigidity of the door structure. I didn't.

In view of the foregoing, it is an object of the present invention to provide a door structure for an automobile which achieves both weight reduction and workability for mounting a glass elevating mechanism at the same time.

[0016]

In order to achieve the above object, in an automobile door structure according to the present invention, an outer panel and an inner panel form a door bag by joining outer edges of both panels. In the case where the inner panel side of the door bag portion is dressed with a door trim,

The guide rails are arranged so as to bridge the opening holes formed so that the portions are opened, the guide rails are coupled to the inner panel, and further, the guide rails and the inside of the guide rails are slidable. An elastic body is provided between the glass mounting portion disposed and mounted on the door glass to give a degree of freedom to the movement of the door glass in the left-right direction of the vehicle body and regulate the movement of the door glass. It is characterized in that it is configured to have a play regulating portion that absorbs.

According to the present invention, since the guide rail bridged to the opening of the inner panel is connected to the inner panel, the rigidity of the inner panel also contributes to the guide rail. An extremely large opening area can be secured.

For this reason, the mounting operation is performed by inserting the glass elevating mechanism from the large opening hole, and the mounting workability is greatly improved, and the weight of the inner panel and thus the door structure itself is reduced. Will contribute.

Also, the door trim is composed of an upper part trim and a lower trim divided into two parts vertically, and the lower part of the door trim is constituted by a sub-assembly of a glass elevating mechanism including a guide rail. If it is formed at a position exposed from the lower trim,
Even if the glass lifting mechanism is sub-assembled to the lower trim, the work of attaching the guide rail to the inner panel together with the lower trim is possible, and the guide rail is pre-mounted on the lower trim so that it does not swing like the conventional guide rail , Can be attached to the inner panel, and the attachment work is simplified.

Further, the connecting point of the guide rail to the inner panel is exposed when the lower trim is mounted on the inner panel, but the connecting point on the upper side is covered by an upper part rim mounted on the inner panel later, and the lower side is connected to the lower side. There is no problem in aesthetics as long as the is positioned below the pocket formed in the lower trim or covered with a cap.

Further, a certain degree of movement of the door glass in the lateral direction of the vehicle body is provided between the guide rail according to the present invention and a glass mounting portion slidably mounted in the guide rail and mounted on the door glass. Because it is configured with an elastic body interposed in order to give and regulate the degree of freedom, it gives the degree of freedom for rolling or pitching of the door glass in the longitudinal direction of the guide rail to absorb various stains on the door glass. To achieve a smooth ascent and descent,
In addition, since the door glass is provided with the play regulating portion that absorbs the play of the door glass in the longitudinal direction of the vehicle body, the degree of parallelism of the door glass with respect to the weather strip or the like on the vehicle body side can be obtained.

According to a second aspect of the present invention, in the first aspect of the present invention, a reinforcing plate is connected to the guide rail so as to cross the guide rail, and the reinforcing plate is connected to the lower trim. It is mounted in advance in a sub-assembly and is arranged so as to be bridged with the opening hole and is connected to the inner plate.

According to the present invention, since the reinforcing plate is disposed so as to cross the guide rail and bridge the opening, and is connected to the inner plate, the rigidity of the inner plate is as follows. The height can be increased in combination with the guide rail, and the opening area of the opening can be further increased.
