Abstract

PURPOSE:To provide a door construction for a vehicle that is easy in assembling of the door and in adjustment of door window panels installed. CONSTITUTION:A door is structurally divided into three independent modules: an outer module A, an up-and-down module B, and an inner module C. The door can be easily completed by assembling these independent modules. It is much better in terms of operability to assemble only necessary parts into individual modules than assembling independent parts one after another into the complete door because each module can be assembled without being interfered by components of other modules. The modules can be assembled into the door also with improved operability because they are assembled in the same direction along the thickness of the door.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Generally, a vehicle door structure has a structure in which parts such as an outer panel, an inner panel, a door window panel, a window regulator and an interior trim are assembled (Nissan Motor Co., Ltd. 1987).
See page B-30 of the monthly service issue “Service Weekly” No. 578). The inner panel is provided with work holes of various sizes, and the work is performed while inserting screws and the like required for assembly into the door through the work holes.

[0003]

However, in such a conventional technique, each of the above-mentioned constituent parts has a structure in which they are assembled together along a series of steps. Therefore, the screwing work from the inside of the door cannot be performed, so that the work using the work hole is increased and the difficult work is forced.

Further, since the individual components are mounted independently of each other, the door window panel can be installed and adjusted only after all the components are assembled to complete the door. When the door window panel is installed and adjusted, it is necessary to consider the mounting error of each of the independently assembled parts, which makes the adjustment operation difficult.

Further, conventionally, the building adjustment of the door window panel has been performed on the basis of the outer panel shape of the door. Therefore, the accuracy of the door window panel installation may be adversely affected by the shape variation of the outer panel, which necessitates a more complicated adjustment work to correct it, making the door assembly work even more troublesome. I am trying.

The present invention has been made in view of such a conventional technique, and provides a vehicle door structure in which the assembling work is easy and the building and adjusting of the door window panel can be easily performed.

[0007]

In order to achieve the above object, a vehicle door structure according to the present invention includes an outer module formed of a structural member having basic strength and rigidity of a door, and a door window panel. And an ascending / descending module integrally provided with an ascending / descending function of a door window panel, and an inner module constituting an interior material of a door, and the modules can be assembled in the same direction along the thickness direction of the door. It has been done.

[0008]

The door structure is divided into three independent modules (outer module, lifting module, and inner module), and the modules are assembled to complete the door, which facilitates the door assembly work. That is,
Compared to the case where individual parts are individually assembled to complete one door, it is better to assemble only the relevant parts and complete each module individually because the work is not disturbed by other module components. The sex is very good. Moreover, even when the completed modules are assembled together, each module can be assembled in the same direction along the thickness direction of the door, so that the workability is greatly improved.

Further, since the raising / lowering function of the door window panel is integrated into one module called the raising / lowering module and independent, the building window adjustment adjustment can be completed in this module. And
In this way, once the building adjustment of the door window panel is completed in the lifting module, there is only "one step" of mounting the lifting module to the outer module, so there is less error in mounting.
Even if it happens, it is easy to correct it.

First, the lifting module B is attached to the outer module A. Step portions A11 and A12 located inside the door are provided at front and rear upper end portions of the inner panel A2 of the outer module A. The step portions A11 and A12 are brackets A13 provided inside the door, It is supported from inside by A14. Further, the front and rear step portions A11, A12 are formed with one mounting hole A15, A16 on the front side and two mounting holes A15, A16 on the rear side. The front and rear upper end portions of the inner panel A2 close to the step portions A11, A12. Has two mounting holes A17 and A18 on the front side and one mounting hole on the rear side.

On the other hand, the inner reinforcement B4 of the lifting module B is the first member B21 on the inner module C side.
And a second member B22 on the outer module A side are joined together to form a kind of hollow structure only on both side portions, and two attachment holes B23 corresponding to the attachment holes A17 are formed on the front side joint portion. A single mounting hole B24 corresponding to the mounting hole A18 was formed in the rear joint. The second member B22 on the outer module A side has a mounting hole B25 corresponding to the mounting hole A15 on the front side, and a mounting hole B2 corresponding to the mounting hole A16 on the rear side.

After positioning the respective mounting holes A15-18 and B23-26, and fixing them by the bolt / nut means B28 using the working hole B27, the lifting module B can be obtained.
Installation is completed. Since the lifting module B is mounted on the outer module A only in the mounting operation along the left-right direction X, the workability is very good. In addition, the inner reinforcement B4 has a hollow structure that is hard to deform on both sides, and the inner reinforcement B4 and the inner panel A2 are installed at a plurality of attachment points (positions of the bolt / nut means B28), and the inner reinforcement B4 is attached. Since the position of the point B28 is set to be shifted in the front-rear direction Y, the left-right direction X, and the up-down direction, the inner reinforce B4 (door window panel B1) can be mounted with higher accuracy and the door rigidity can be improved. .. The diameter of each of the mounting holes A15 to 18 and B23 to 26 has a margin to the bolt diameter of the bolt / nut means B28, and within this margin range, the front and rear direction Y of the inner reinforcement B4 with respect to the inner panel A2. Subtle position adjustments can be made in the vertical direction (in-plane direction).

Next, how to attach the inner module C to the lifting module B will be described. Inner module C
Since the locate pin C6 is projected on the inner module C, the inner module C is set in the elevating module B along the left-right direction X, and the locate pin C6 of the inner module C is located in the inner reinforcement B4 of the elevating module B. Insert into hole B20. The position of the inner reinforcement B4 with respect to the inner module C is ensured by the correspondence between the locate pin C6 and the locate hole B20, and hence the inner module C is inserted through the mounting hole C8 of the recess C9 provided in the armrest C7. Screw B29 to the L-shaped bracket B1 of the lifting module B
7 is screwed into the screw hole B16, and the grip C
The basic mounting is completed by screwing the screw B30 inserted from the mounting hole C11 at the upper end of 10 into the screw hole B18 of the bracket B19 fixed to the waist bracket B6 on the lifting module B side. After the basic mounting work is completed, the mounting work of the inner module C is completed by clipping the periphery of the inner reinforcement B4 to predetermined positions of the inner panel A2 and the inner reinforcement B4, respectively. .. The door thus completed has a waist opening (a gap between the upper side portion of the outer panel A1 and the inner reinforcement B4) through which the door window panel B1 comes in and out, which is smaller than that of the conventional door. The overall rigidity of is greatly improved. The stabilizer for supporting the door window panel B1 conventionally provided in the waist opening is eliminated to reduce the weight.

[0022]

The door structure for a vehicle according to the present invention has the contents described above, and the door structure is divided into three independent modules (outer module, lifting module, inner module), and Since each module can be assembled in the same direction, the door assembling work becomes very easy and the door assembling work can be easily automated. Further, since the lifting function of the door window panel is integrated into one module called the lifting module and is independent, the building window adjustment adjustment can be completed in this module.
