DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In general, a door for an automobile includes a glass plate (a plate material for a window) that opens and closes a window opening, and a door body that is disposed below the window opening and has a storage portion that can store the glass plate. And a window regulator (elevating means) for elevating and lowering the glass plate between the window opening and the storage part.

[0003] In recent years, in order to simplify the assembling process, modularization of members composing an automobile door has been promoted. As a door module, there is a door module in which a door fitting component including a glass plate and a window regulator is integrally held by a module panel as a base material. When attaching the door module to the door body, first, the worker holds the door module and moves appropriately, and places a glass plate or the like in the storage section through the attachment opening provided in the inner panel (inside the vehicle interior) of the door body. To be done. Then, by inserting a pin provided on the inner panel into a mounting hole provided on a peripheral portion of the module panel, positioning and temporary fixing of the door module with respect to the door body are performed.

[0004]

When a door module is mounted on a door body, a glass plate or a window regulator, which is a component having a large outer dimension, easily interferes with an inner panel of the door body. Therefore, the work of attaching the door module to the door body is complicated. Also, after the glass plate etc. can be placed in the storage section, the worker holds the door module until the pin of the inner panel is inserted into the mounting hole on the peripheral edge of the module panel and the door module is temporarily fixed to the door body This has increased the burden on the workers and reduced the work efficiency. Furthermore, recently, assuming recycling, it has been demanded to be able to easily and quickly remove a glass sheet for an automobile window from a vehicle body. The present invention has been made in view of such circumstances, and an object of the present invention is to provide an automobile door that is easy to assemble and easy to disassemble.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a storage portion which is disposed below a window opening of an automobile and which can store a window plate for opening and closing the window opening. A door body having an ascending and descending opening of the window plate material arranged along the belt line, and a mounting opening provided on the inside surface of the vehicle and communicating with the ascending and descending opening, and the window plate material, and the window plate material A door outfitting part including an elevating means for elevating and lowering the space between the window opening and the storage part has a door module integrally held by a base material, and the door module is provided through the mounting opening. An automobile door attached to the door body, wherein the base material has a belt line frame extending in a front-rear direction along the belt line, and one end and the other end of the belt line frame in a front-rear direction. Each The first receiving portion is supported by a first receiving portion and a second receiving portion provided on the door body, and the first receiving portion supports, at one end of the belt line frame, an outside supporting surface that supports an outside surface and a lower surface. A lower support surface,
The second receiving portion has an end support surface that supports an end surface of the other end of the belt line frame, and provides an automobile door.

In this specification, "front", "rear", "up", "down", "inside", and "outside" used to indicate a direction and a position are such that an automobile door or an automobile door module is attached to a vehicle body. "Before""after""up""down""inside""outside"
Means In the present invention, examples of the window plate include transparent or translucent glass plates and resin plates. A chromatic glass plate or a resin plate may be used as long as it has sufficient transparency. Examples of the glass plate include a single glass plate and a laminated glass. Further, the glass plate may be subjected to a strengthening treatment or a functional coating treatment such as a heat ray reflection film.
Examples of the door body include a door body formed of a metal outer panel and an inner panel, and a door body formed of a resin plate. As the elevating means, a so-called single lift type having one guide member extending in the vertical direction can be exemplified. Alternatively, a type in which a wire is routed between pulleys provided vertically without a guide member may be used.

The configuration of the base material other than the belt line frame is arbitrary, and the base material may be formed by combining the belt line frame with another frame material, or by combining the belt line frame with the panel material. A substrate may be formed. It is preferable to form the base material by combining the belt line frame with another frame material from the viewpoint of reducing the weight. When a base material (module frame) is formed by combining a belt line frame with another frame material, the side view (when viewed in the direction penetrating the window plate material (the thickness direction of the window plate material)) It is preferable that the front-back dimension of the upper portion of the substrate is larger than the front-back dimension of the lower portion. There is no limitation on the form of the belt line frame, and examples thereof include a cylindrical shape, a flat shape, a U-shaped cross-section (C-shaped cross-section), and an I-shaped cross-section. From the viewpoint that the weight can be reduced while securing the rigidity, a cylindrical shape is preferable, and a cylindrical shape having a substantially sun-shaped cross section is more preferable.

[0008] According to the above configuration, since the elevating opening and the mounting opening are continuous, when the door module is mounted on the door main body, the window plate or the elevating means interferes with the inner side surface of the door main body. do not do. When attaching the door module to the door body, one end and the other end of the base material in the front-rear direction of the belt line frame can be supported by the first receiving portion and the second receiving portion provided on the door body, respectively. . When the one end and the other end of the belt line frame are supported by the first receiving portion and the second receiving portion, the belt line frame is positioned in the front-rear direction, the up-down direction, and the inside and outside directions, and at the same time, the operator has one or both hands. It can be released from the door module. That is, the one end and the other end of the belt line frame are supported by the first receiving portion and the second receiving portion, so that the positioning and the temporary fixing of the door module are simultaneously performed. Thus, the positioning and temporary fixing of the door module to the door body can be easily performed. Therefore, the door module can be easily attached to the door body, and the automobile door of the present invention is easy to assemble. In addition, when the door module is removed from the door body, since the elevating opening and the mounting opening are continuous, the window plate or the like does not interfere with the door body.
Therefore, the door module can be easily removed from the door body, and the window plate and the like can be easily recycled. In the above-mentioned automobile door, the belt line frame contributes to the door rigidity, thereby suppressing a decrease in the door rigidity near the belt line.

In the present invention, the first receiving portion provided on the door body may have an end supporting surface opposed to an end surface of one end of the belt line frame at a predetermined interval in a state fixed to the door body. preferable. By providing the end support surface also in the first receiving portion, one end and the other end of the belt line frame are separated from the front-back direction by the end supporting surface of the first receiving portion and the end supporting surface of the second receiving portion. Become supported. In other words, the belt line frame functions more effectively as a reinforcing material for suppressing deformation of the door body. In addition, since the end support surface of the first receiving portion is set at a predetermined interval to the end surface of one end of the belt line frame in a state where the belt line frame is fixed to the door main body, there is some clearance. In addition, there is no difficulty in attaching the belt line frame to the first receiving portion and the second receiving portion. This predetermined interval is preferably in the range of 0.5 to 5 mm. If the distance between one end of the belt line frame and the end supporting surface of the first receiving portion is 0.5 mm or more, a dimensional error of the belt line frame and / or the first receiving portion can be sufficiently tolerated, and the belt line frame can be used. It can be securely and easily assembled to the door body. Also, if the distance between one end of the belt line frame and the end support surface of the first receiving portion is set to 5 mm or less, door rigidity is secured even when a load is applied in the front-rear direction of the door body due to a frontal collision of a vehicle or the like. it can. In the base material of the present invention, at least the belt line frame is preferably disposed on the vehicle interior side than the window plate material, and particularly preferably the entire base material is disposed on the vehicle interior side than the window plate material. . That is, in the present invention, the mounting opening in the present invention communicates with the lifting port in order to facilitate the work of mounting the door module. For this reason, if nothing is attached at a position along the belt line, the strength of the entire door decreases. Therefore, in the present invention, the belt line frame is provided at a position along the belt line. By arranging the belt line frame on the inner side of the vehicle than the window plate, the elevator is located between the belt line frame and the outer panel of the door body, and the thickness of the door near the belt line can be reduced. Furthermore, by arranging the entire base material inside the vehicle than the window plate, the thickness of the entire door can be reduced.
