Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Generally, a vehicle door includes a glass plate (a plate material for a window) that opens and closes a window opening, and a door body having a storage portion that is arranged below the window opening and can store the glass plate. , And a window regulator (elevating means) for raising and lowering the glass plate between the window opening portion and the storage portion. The glass plate moves up and down through an elevating port provided along the belt line of the door body.

Recently, in order to simplify the assembly process, modularization of members constituting an automobile door has been advanced. 2. Description of the Related Art As a door module, there is one in which door fitting parts including a glass plate and a window regulator are integrally held by a module panel as a base material. The door module is assembled to the door body such that a glass plate or the like is arranged in a storage portion of the door body through a mounting opening provided in an inner panel (side surface inside the vehicle) of the door body.

[0004]

When the door module is assembled to the door body, the glass plate and the window regulator, which are parts having large outer dimensions, are likely to interfere with the inner panel or the like of the door body. Therefore, the work of assembling the door module to the door body is complicated. In particular, when the base material of the door module is plate-shaped, the door module tends to be heavy, and the operator or the automatic means such as a robot tends to have a heavy load. To make it easier to assemble the door module to the door body, make the inner panel mounting opening larger, or remove the part along the belt line of the inner panel (belt line part) so that the mounting opening communicates with the elevating port. Can be considered. However, this reduces the strength (rigidity) of the entire door. Although it is conceivable to add a reinforcing material to the door module in order to suppress the decrease in the door rigidity, this makes the door module heavy and reduces the workability of assembling the door module. The present invention has been made in view of the above circumstances, and an object thereof is to provide an automobile door and an automobile door module for the automobile door, in which the assemblability is improved while maintaining the door rigidity.

[0005]

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 plate material for opening and closing the window opening. A door body having an elevating port of the window plate member provided along a belt line and a mounting opening provided on a side surface inside the vehicle, the window plate member, and the window plate member being the window opening portion and A door fitting component including a raising / lowering unit having a driving unit for raising and lowering between the storage units and a latch for locking is provided as a door module integrally held by a module frame, and the door module is mounted by the mounting. An automobile door mounted to the door body through an opening, wherein the module frame is formed in an annular shape in a side view, and the drive frame is provided on one side in the front-rear direction of the module frame. Part is arranged and the latch is arranged on the other side, the drive part is arranged inside the ring of the module frame and the latch is arranged outside the ring, and the latch is arranged outside the ring on the upper side of the module frame. A mounting portion having a protruding bracket is provided at a position that maintains a weight balance in the front-rear direction with respect to a vertical line passing through the center of gravity of the door module, and the door module is mounted through the mounting portion to the mounting opening of the door body and the ascending / descending position. Provided is an automobile door characterized by being locked to a belt line portion between the mouth. Further, according to the present invention, a door fitting component including a window plate member for opening and closing a window opening of an automobile, a lifting unit having a driving unit for lifting the window plate member, and a latch for locking is integrated with a module frame. Are held in the window opening portion and are arranged below the window opening portion, and are capable of storing the window plate material; an elevating port of the window plate material provided along the belt line; A door body for a vehicle having a mounting opening provided therein, the door module being mounted on the door body through the mounting opening, wherein the module frame is formed in an annular shape in a side view, and the module frame is in the front-back direction. The drive unit is arranged on one side and the latch is arranged on the other side, and the drive unit is arranged inside the ring of the module frame and is arranged outside the ring. A latch is arranged, and an attachment portion having a bracket projecting outside the ring is provided on the upper side of the module frame at a position where a weight balance between the front and the back with respect to a vertical line passing through the center of gravity of the door module is maintained. A door module for an automobile is provided, which is locked to a belt line portion between the attachment opening of the door body and the elevating port.

In the present specification, "front", "rear", "upper", "lower", "inside", "outer" and "vertical" used to indicate directions and positions refer to an automobile door or an automobile door module as a vehicle body. "Front""rear""up""bottom" when attached to
It means “inside”, “outside”, and “vertical”. In the present specification, the side view refers to the case of being viewed in a direction that penetrates the window plate material (the thickness direction of the window plate material). The upper side of the belt line frame is not limited to a straight side, but may be a curved side or a side formed by connecting a plurality of straight lines.

According to the above construction, when the door module is locked to the belt line portion of the door body through the mounting portion on the upper side of the module frame, the operator releases one or both hands from the door module. Is possible.
That is, even before the door module is permanently fixed to the door body, if the door module is temporarily fixed to the belt line part of the door body via the mounting portion, the door module will have the same posture as when the door module was fully fixed. And, it is held on the door body without losing the balance. Therefore, the operator or the robot does not have to support the door module until the main fixing is completed. According to the above configuration,
Leave the belt line part of the door body without removing it, and
By making the module frame annular, the rigidity of the door and door module is secured. Also, by adopting an annular module frame instead of a panel shape,
The door module is lighter. Thus, the assemblability of the door module to the door body is improved without reducing the door rigidity. Furthermore, the door module can be miniaturized by disposing the drive unit in the annular module frame in a side view and effectively utilizing the space in the module frame as a storage space for the drive unit. As a result, the assemblability of the door module to the door body is improved.

It is preferable that there are a plurality of mounting portions on the upper side of the module frame, and that each of the plurality of mounting portions is arranged in front of and behind the intersection of the vertical line passing through the center of gravity of the door module and the upper side. With this configuration, the door module can be stably held by the door body when temporarily fixed. With respect to the plurality of mounting portions provided on the upper side of the module frame, if the position of one of the mounting portions is determined, the position of the other mounting portion is also determined. Therefore, the assemblability of the door module to the door body does not deteriorate. It is also preferable that the mounting portion on the upper side of the module frame is arranged on a vertical line passing through the center of gravity of the door module. With this configuration, when the door module is temporarily fixed to the belt line portion of the door body through one mounting portion, the door module is in the same posture as when the door module is fully fixed, and the door body does not lose its balance. Held in. Since only one mounting portion needs to be locked to the belt line portion of the door body, the door module can be easily attached to the door body.

In the present invention, a transparent or semi-transparent glass plate or a resin plate can be exemplified as the window plate material. 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 laminated glass. Further, the glass plate may be one that has been strengthened or functionally coated with a heat ray reflective film or the like. Examples of the door body include those formed of a metallic outer panel and inner panel, and those formed of a resin plate. Examples of the elevating means include a wire type regulator having pulleys on the upper and lower portions of the door body, and a regulator composed of a rack and a pinion extending vertically. As the wire type regulator, for example, a so-called single lift type regulator having one vertically extending guide member (guide rail) can be adopted. The rigidity of the door can be improved by fixing, for example, the lower end of the guide rail to the inner panel of the door body or the like.

There is no limitation on the form of the members constituting the module frame, and those having a U-shaped section (C-shaped with corners),
Examples thereof include a cylindrical shape, a flat shape, and an I-shaped cross section. A module frame including a member having a U-shaped cross section having a back plate and a pair of side plates standing on the back plate is preferable in terms of weight saving while ensuring rigidity. In this case, the back plate of the module frame is placed outside the vehicle,
It is preferable to open the U-shaped recess toward the inside of the vehicle. This makes it possible to easily fix the substrate or bracket of the drive unit and the back plate of the module frame by spot welding or fastening. That is, the door fitting parts can be easily fixed to the module frame. The module frame is
It is also possible to bend and form a single frame member having a U-shaped cross section having a back plate and a pair of side plates standing upright from the back plate. That is, the frame member is formed into a long shape by extrusion molding of aluminum or the like. At this time, the back plate and the side plate standing upright from the back plate are integrally extruded, and one frame member is formed so as to form a U-shaped recess defined by the back plate and both side plates. After that, the frame member is cut into a predetermined length (a length substantially corresponding to the entire circumference of the module frame). The module frame is formed by bending the cut frame member into a predetermined shape. 1
Forming the module frame by bending the book frame members is preferable because it can reduce the number of parts as compared with the case where the module frame is formed by coupling a plurality of frame members.

The form of the mounting portion is not limited, and examples thereof include a bracket having mounting holes, a bracket having mounting pins and mounting hooks, and the like. It is preferable to use a bracket having a mounting hole into which a bolt (stat bolt) provided in the belt line portion of the door body can be inserted. In this case, by fastening the nut to the bolt fitted in the mounting hole, the bolt and the mounting portion can have not only the function of temporary fixing but also the function of main fixing.
That is, it is not necessary to separately provide a mounting member for the main fixing.

It is preferable that the drive unit of the elevating means fixes a substrate supporting the drive unit to the module frame and attaches to the module frame via the substrate. in this case,
At least the upper edge or the lower edge of the board is preferably fixed to the module frame, and the length between the upper and lower edges of the board (the vertical dimension of the outer shape of the board) and the upper and lower edges of the upper edge of the module frame It is preferable that the length between the lower end and the length (dimension in the vertical direction of the outer shape of the module frame) substantially coincides. As a result, the outer dimensions of the module frame can be made as small as possible, and the weight of the door can be reduced and the assembling of the door module to the door body can be improved.
In addition, "generally coincident" means that the sizes of the two are slightly different from each other within a range in which the weight can be reduced and the assembling property can be improved. If the dimensions of the two are slightly different,
For example, when the board slightly projects outside the ring of the module frame (the vertical dimension of the outer shape of the module frame is slightly smaller than the vertical dimension of the outer shape of the board), or either the upper edge or the lower edge of the board One side and the side edge of the board may be fixed to the module frame (the outer dimension of the module frame in the vertical direction is slightly larger than the outer dimension of the board in the vertical direction).

The following method can be adopted as a method of assembling the door module to the door body. That is, a storage portion that is disposed below a window opening of an automobile and that can store a window plate material that opens and closes the window opening, an elevating port of the window plate material that is provided along a belt line, and an interior of the vehicle. A door body having a mounting opening provided on a side surface, the window plate member, an elevating unit having a drive unit for elevating the window plate member between the window opening section and the storage unit, and a latch for locking. In a vehicle door having a door module that is integrally held by a module frame, the door fitting part including the above is a method for assembling a vehicle door module, wherein the door module is assembled to the door body through the mounting opening. The door module is oriented so that the window plate member is along a surface that intersects the opening surface of the mounting opening at a predetermined angle, and the door module is After the pitch side is inserted into the mounting opening,
