Abstract

PURPOSE:To prevent the stress concentration at a hinge portion, facilitate assembling, and resolve the hue difference after coating by temporarily fixing an outer panel to a vehicle body with a jig, coating them together, removing it after drying, separately assembling accessory parts to an inner panel, fitting it to the vehicle body, and fastening it together with the outer panel. CONSTITUTION:An outer panel main body 1 is temporarily fitted to a vehicle body with a jig, and the vehicle body and the outer panel main body 1 are concurrently coated. The outer panel main body 1 is removed after a paint is dried. An inner panel main body 10 coated separately and a door rim 14 are connected, and door inner parts are assembled to the inner panel main body 10. A completed door inner is assembled to the vehicle body, and door adjustment is performed. The outer panel main body 1 and the inner panel 10 with a door trim 14 are connected with bolts 3. The door rim 14 and the outer panel main body 1 are reinforced, the outer panel 1 and the vehicle body can be concurrently coated, the occurrence of the hue difference can be prevented, and the assembling work is facilitated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door and a method of handling the same in an automobile manufacturing process.

0002

2. Description of the Related Art Conventionally, door parts made by integrally welding an outer panel and an inner panel formed by press working are used in automobile manufacturing and assembly processes. After hinge-joining this door to the body, assemble the door (window regulator, door lock complete, key cylinder, lock release, door window glass, etc.)
and door adjustments (hinge, door striker).

0003

However, this door component is bulky and expensive. The door is assembled from the inside of the vehicle with the door open, which tends to cause stress to be concentrated at the hinge and is inefficient. The installation of the window regulator, door lock complete, key cylinder, lock release, door window, and glass is more cramped than the openings dotted in the inner panel. Also, when painting non-metallic doors, including the door outer panel and inner panel, the body and door are painted separately, so
There was a hue difference in the metallic paint.

[Means for Solving the Problems] Therefore, in order to eliminate the above-mentioned drawbacks, the present invention provides an outer panel of an automobile door and an inner panel with a door trim that are retrofitted, the inner panel being used as a vertical stile, and the inner panel being used as a stile. Based on the automobile door and door jig, the door hinge body and door striker are attached to the body in advance, and only the outer panel is painted together with the body via the jig, and after drying. The present invention seeks to provide a method for handling the automobile door, which comprises removing the door, incorporating a lock and a regulator into a separately painted inner panel, attaching the door hinge to the door hinge, and attaching an outer panel to the inner panel. be.

[Embodiment] An embodiment of the automobile door of the present invention will be described based on the drawings.The outer panel of the automobile door is provided with a press-molded outer panel body (1), and a stiffening material is provided approximately in the center of the body. An impact bar (2) is installed horizontally, stud bolts (3) etc. are installed at appropriate intervals on both ends and the lower end of the outer panel body (1), and a reinforcing edge (4) is installed at the upper end of the outer panel body (1). ) and weather strip (5). In addition, install the handle cover (6).

[0006] The inner panel is the vertical stile (7) on both sides.
(8) are connected in an H-shape with a sill (9) to form an inner panel main body (10), and a door sash assembly (11) is installed across the vertical stile (7) and (8). Also reinforced edges (
12), and a flange portion (13) for receiving the stud bolt (3) of the outer panel main body (1) is formed.

The door trim (14) covers and is fixed to the inner panel body (10).

This is an automobile door in which the above-described outer panel body (1) and inner panel body (10) with a door trim (14) are retrofitted using stud bolts (3).

[0009] One embodiment of the above-mentioned method for handling automobile doors in the automobile manufacturing process includes: 1) determining the door position on the body after assembly based on a master door (hereinafter referred to as a jig) in the car body assembly process; Determine and attach the hinge and door striker to the body. 2) Temporarily assemble the outer panel main body (1) to the body using a jig.

[0010] In the painting process, the body and the outer panel body are painted at the same time.

In the vehicle assembly process, 1) the outer panel main body (1) is removed from the body. 2) Joining the separately painted inner panel body (10) and door trim (14). 3) Assemble the door internal parts to the inner panel body (10). 4) Attach the door inner completed in 3) to the body. door adjustment. 5) Attach the outer panel body (1). 6) Assembly of door exterior parts.

[0012] Normally, a bending moment and a shearing force are applied to the door using the hinge portion as a fulcrum. The horizontal load and vertical load are slight, and if the vertical stile (7) near the hinge part where local stress occurs even if the load is applied, and the vertical stile (8) related to the door striker have sufficient strength, it is sufficient. The vertical frames (7) and (8) are connected by a sill (9) that has a width-thickness ratio that transmits stress and prevents buckling and twisting, and connects this to the door trim (14) and outer panel. Main body (1)
Since the walls are reinforced, the effective ratio of the wall ratio is improved, and sufficient strength as a door can be obtained. Spaces other than the stiles (7), (8) and the sills (9) can be used as openings. Further, when the door is closed from the outside of the car (before the outer panel is attached), the door can be assembled from the outside of the car.

[0013] In the case of a bonnet, a trunk lid, or a sliding roof, an outer panel and an inner panel formed by press processing are joined together. It is easy to analogize what can be accomplished as follows.

[0014]

As a result, the weight and cost of the door can be reduced, and damage to the door can be dealt with simply by modifying or replacing the outer panel, which is economical. If the inner panel and door trim are integrally molded with resin, the indoor side will be completely protected from rain, eliminating the need for waterproof doors, inside screens, etc. that are conventionally installed on doors. It becomes easy to integrate the door internal parts with the inner panel and door trim, and to improve the fixing method. Since the outer panel and the inner panel can be painted separately, the degree of freedom in design is improved, and since the outer panel and the body can be painted at the same time, it is possible to prevent hue differences from occurring. In addition, since the above-mentioned separate painting is possible, each part of the door can be painted according to its rust prevention ability, and rust prevention measures (such as application of rust preventive agent) after painting are unnecessary. The inner panel that faces the inside of the vehicle is painted in the interior color to eliminate any discomfort in the interior of the vehicle. Since the door assembly work surface has a large opening, the installation work is easy, and if resin integral molding is adopted, positioning guides for each part can be easily set, making automatic assembly easier. With the door installed on the body (no outer panel attached), it is possible to adjust the door, adjust the glass of a hardtop vehicle, and check for water leaks into the cabin from the outside of the vehicle, making quality maintenance easier.
