Description

  The present invention relates to a door structure of an automobile in which an upper end portion is attached to a vehicle body side via a hinge.

  Conventionally, a back door of an automobile is configured as shown in FIG. In FIG. 5, the back door 100 of the automobile is supported so as to be swingable with respect to an opening 102 d provided at the rear of the vehicle body of the automobile 102 by a hinge portion (not shown). ing. Here, the back door 100 is comprised from the inner panel 100a and the outer panel 100b (refer FIG. 6) each press-formed from the steel plate.

  Further, as shown in FIG. 6, the back door 100 is provided with a pair of left and right cushion rubbers 103 on the passenger compartment side of the lower end portion of the inner panel 100 a. These cushion rubbers 103 abut against the abutment surface 104a of the lower panel 104 on the vehicle body side when the back door 100 is closed, so that the closing direction of the position of the back door 100 with respect to the vehicle body is regulated. Thereby, what is called the building performance of the back door 100 improves.

Further, since the back door 100 is always in contact with the vehicle body via the cushion rubber 103, resonance of the back door 100 during idling or the like is suppressed, and so-called NV performance is improved.
Further, when the back door 100 is strongly closed, the cushion rubber 103 is interposed between the back door 100 and the vehicle body, so that the back door 100 and the vehicle body are protected.

  In the illustrated case, the lower panel 104 is covered with a rear bumper 105, and only the contact surface 104 a is exposed by a window-like portion 105 a provided on the rear bumper 105.

Incidentally, in the above-described automobile back door 100, the distance d between the cushion rubber 103 and the lower panel 104, that is, the mounting surface 100c of the cushion rubber 103 on the inner panel 100a of the back door 100 and the contact surface 104a of the lower panel 104, The interval may be different on the left and right.
In such a case, conventionally, in the metal back door 100, in a so-called touch-up process, the back door 100 itself is twisted and plastically deformed by using a mold and a jig, so that the distance d between the left and right surfaces is reduced. Can be aligned.

However, in the back door 100, when the inner panel 100a and the outer panel 100b are made of resin, it is difficult to plastically deform the back door 100, so that the distance d between the left and right surfaces is made uniform by deformation of the back door 100 itself. Is difficult.
Accordingly, when the distance d between the left and right surfaces is different from each other, either the left or right cushion rubber 103 is not separated from or brought into close contact with the contact surface 104a of the lower panel 104, and the NV performance is impaired.

  Furthermore, regarding such door installation accuracy, the same applies to not only the back door but also doors provided in other parts of the automobile.

  SUMMARY OF THE INVENTION In view of the above, the present invention provides a vehicle door structure that has a simple configuration and can easily improve the installation accuracy by aligning the left and right surfaces even with a resin door. The purpose is that.

  According to the present invention, the door body having an inner panel and an outer panel is attached to the vehicle body via a hinge provided at the upper end, and a pair of left and right cushion rubbers are provided at the lower end of the inner panel. In the automobile door structure, the mounting surface of each cushion rubber on the inner panel is inclined in the vertical direction with respect to the contact surface of the cushion rubber on the lower panel on the vehicle body side, and each cushion rubber is in contact with the mounting surface. This is achieved by an automobile door structure characterized in that it is mounted so that its position can be adjusted in the vertical direction.

  In the door structure of an automobile, the mounting holes for the cushion rubbers on the mounting surface of the inner panel are preferably formed long in the vertical direction.

  In the door structure of an automobile, the mounting holes for the cushion rubbers on the mounting surface of the inner panel are preferably composed of a plurality of mounting hole portions separated by a predetermined distance in the vertical direction.

  In the door structure of the automobile, preferably, the mounting hole portions communicate with each other in the vertical direction.

  The door structure of the automobile is preferably formed such that the front end surface of each cushion rubber contacting the lower panel on the vehicle body is curved in a convex shape.

  According to the above configuration, for example, in the touch-up process of the door such as a back door, the space between the mounting surface of the cushion rubber on the inner panel of the door and the corresponding contact surface of the lower panel on the vehicle body side is When the left and right are different, the position of one cushion rubber is adjusted in the vertical direction with respect to the mounting surface of the inner panel. As a result, the cushion rubber mounting surface of the inner panel is inclined with respect to the cushion rubber contact surface of the lower panel, so the distance between the cushion rubber mounting heights changes by adjusting the height of the cushion rubber. To do.

  Accordingly, by adjusting the height of the cushion rubber appropriately, the left and right cushion rubber mounting positions are aligned on the left and right sides, so that the door installation accuracy is improved and the NV performance is improved. In this case, since plastic deformation due to twisting of the door as in the prior art is unnecessary, a mold and a jig for this are not necessary, and the door can be easily and easily made of resin or metal. It is possible to surely align the surfaces.

  When the mounting holes for each cushion rubber on the mounting surface of the inner panel are long in the vertical direction, the cushion rubber moves in the vertical direction along this mounting hole, so that The position of the direction can be adjusted.

  When each cushion rubber mounting hole on the mounting surface of the inner panel is composed of a plurality of mounting hole portions separated by a predetermined distance in the vertical direction, each cushion rubber is attached to one of the mounting hole portions. As a result, the vertical position of each cushion rubber can be adjusted.

  When the mounting hole portions communicate with each other in the vertical direction, it is possible to provide each mounting hole portion at an interval shorter than the size, and to perform finer position adjustment of each cushion rubber in the vertical direction. it can.

  If the front end surface of each cushion rubber that contacts the lower panel on the vehicle body is curved in a convex shape, the front end surface is elastically deformed, so that there is a slight gap between the cushion rubber mounting positions. The difference can be absorbed.

  As described above, according to the present invention, there is provided a vehicle door structure that can easily improve the installation accuracy by easily aligning the left and right surfaces even with a resin door. be able to.

It is a schematic perspective view which shows the motor vehicle provided with an example of the conventional back door structure. It is a partial expanded sectional view which shows the structure of the principal part of the back door structure of FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a configuration of a main part of an embodiment of a back door structure of an automobile to which the present invention is applied.
In FIG. 1, a back door structure 10 for an automobile includes a back door 11 supported so as to be swingable so that it can be opened outwardly by a hinge part with respect to an opening provided at the rear part of the body of the automobile. And a lower panel 12 constituting the lower part of the opening.
Here, the back door 11 includes a resin inner panel 11a and an outer panel 11b.

  Further, as shown in FIG. 1, the back door 11 is provided with a pair of left and right cushion rubbers 13 on the vehicle compartment side of the lower end portion of the inner panel 11 a. When the back door 11 is closed, these cushion rubbers 13 come into contact with the contact surface 12a of the lower panel 12 on the vehicle body side, so that the position of the back door 11 with respect to the vehicle body is regulated in the closing direction.

  The above configuration is the same as that of the conventional back door structure shown in FIGS. 5 and 6, but in the back door structure 10 of the automobile according to the embodiment of the present invention, the lower end of the inner panel 11 a of the back door 11. The mounting surface 14 of the cushion rubber 13 in the portion is inclined with respect to the contact surface 12a of the lower panel 12 by an angle θ with respect to the vertical direction. With this configuration, the inter-surface distance d between the mounting surface 14 and the contact surface 12a can be changed by shifting the cushion rubber 13 in the vertical direction.

  Further, as shown in FIG. 2, the mounting holes 15 of the cushion rubber 13 in the mounting surface 14 are composed of a plurality of, in the illustrated case, three mounting hole portions 15a, 15b, 15c arranged in a vertical direction. Has been. In the illustrated case, the mounting hole portions 15a, 15b, and 15c are arranged at intervals smaller than their sizes (diameters) and communicate with each other.

  Further, the tip end surface 13a of the cushion rubber 13 is formed to be convexly curved as shown in FIG.

  In the illustrated case, the lower panel 12 is covered with a rear bumper 16, and only the contact surface 12 a is exposed at a window-like portion 16 a provided on the rear bumper 16.

  The vehicle back door structure 10 according to the embodiment of the present invention is configured as described above, and is assembled and adjusted to the vehicle body as follows.

  First, the left and right cushion rubbers 13 are attached to the attachment hole portion 15b in the center of the attachment hole 15 on the attachment surface 14, and the back door 11 is attached to the vehicle body. At this time, in the closed state of the back door 11, the front end surface 13 a of the cushion rubber 13 comes into contact with the contact surface 12 a of the lower panel 12 as shown in FIG. 1.

  Thereafter, in the touch-up process, the mounting of the back door 11 to the vehicle body is adjusted. However, when the mounting is a so-called exact size, the back door 11 is pressed against the cushion rubber 13 as shown in FIG. By contact with the contact surface 12a, the vehicle body is regulated in a closing direction at a predetermined position with respect to the vehicle body.

  When the construction of the back door 11 is too close to the vehicle body, as shown in FIG. 3, the cushion rubber 13 is attached to the mounting surface 14 below the mounting hole 15 as shown by the arrow A1. It moves to the part 15c and is attached.

  By doing in this way, since the mounting height of the cushion rubber 13 moves downward, the cushion rubber 13 comes into contact with the contact surface of the lower panel 12 at a lower position. Therefore, since the inter-surface distance d described above is reduced, the back door 11 is regulated in the closing direction by the cushion rubber 13 at a position further away from the vehicle body as indicated by an arrow A2. That is, the installation position of the back door 11 moves further to the rear of the vehicle.

  On the other hand, when the back door 11 is installed too far from the vehicle body, as shown in FIG. 4, the cushion rubber 13 is mounted on the mounting surface 14 above the mounting hole 15 as shown by an arrow B1. It moves to the hole portion 15a and is attached. As a result, the mounting height of the cushion rubber 13 moves upward, so that the cushion rubber 13 contacts the contact surface of the lower panel 12 at a higher position. Accordingly, since the above-described distance d between the surfaces is increased, the back door 11 is regulated in the closing direction by the cushion rubber 13 at a position closer to the vehicle body as indicated by an arrow B2. That is, the installation position of the back door 11 moves further forward of the vehicle.

  Further, the mounting position of the cushion rubber 13 is limited to the three stages of the mounting hole portions 15a, 15b, and 15c of the mounting hole 15, but the tip end surface 13a of the cushion rubber 13 is curved in a convex shape. The difference in the distance d between the left and right surfaces at each stage can be absorbed to some extent by the elastic deformation of the tip surface 13a.

In this way, with respect to the mounting hole 15 in the mounting surface 14 provided in the inner panel 11a of the back door 11, the mounting rubber portion 13a, 15b or 15c for mounting the cushion rubber 13 is appropriately selected and the cushion rubber 13 is mounted. Thus, the installation position of the back door 11 can be adjusted based on the inclination of the mounting surface 14 with respect to the contact surface 12a.
Therefore, the right and left mounting accuracy of the back door 11 is improved and the NV performance is also improved without twisting and deforming the back door 11 in the touch-up process as in the prior art. At that time, since the plastic deformation of the back door 11 itself is not performed, a mold or jig for plastic deformation of the back door 11 is not necessary, and even the resin-made back door 11 is adjusted for installation. be able to.

However, the present invention is not limited to this, and so-called front doors or rear seats for other doors, driver seats, and passenger seats. The present invention can also be applied to doors including sliding doors.

  In the embodiment, the three mounting hole portions 15a, 15b, 15c of the mounting hole 15 communicate with each other, but are arranged at intervals longer than the size (diameter) of these mounting hole portions 15a, 15b, 15c. In this case, the mounting hole portions 15a, 15b, and 15c do not communicate with each other.

  Furthermore, although the attachment hole 15 has the three attachment hole parts 15a, 15b, and 15c, it is not restricted to this, You may have two or four or more attachment hole parts. As a result, the height of the cushion rubber 13 can be adjusted in two steps or four or more steps in the vertical direction.

  The mounting position of the cushion rubber 13 is limited to three stages of the three mounting hole portions 15a, 15b, and 15c of the mounting hole 15. However, the mounting position is not limited to this, and the mounting hole 15 is a long hole extending in the vertical direction. Thus, it is possible to continuously adjust the position in the vertical direction in a stepless manner.

  In the above-described embodiment, the case of the resin back door 11 has been described. However, the present invention is not limited to this, and the back door 100 includes a conventional metal inner panel 100a and an outer panel 100b as shown in FIG. However, it is clear that the present invention can be applied.
