Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning structure for welding parts of an automobile door, and more particularly to a positioning structure for welding a sash frame to a window opening of an inner panel of an automobile door.

[0002]

2. Description of the Related Art In an automobile door 1 as shown in FIG.
Various welded parts are welded to the inner panel, which is one of the main structural parts, until completion. Among these welded parts, the sash frame is to be welded to the portion forming the window opening of the inner panel.
FIG. 5 shows, as an example, a state in which the sash frame 2 is welded to the inner panel 3 of the automobile door 1. The sash frame 2 is welded to the inner panel 3 to form a reinforcing frame having a closed cross section in the window opening (having a partition space such as 4 in FIG. 5).

When welding the sash frame 2 to the inner panel 3, the position on the plane including the automobile door 1 is relatively easily determined by the shape of the window opening 5 provided in the inner panel 3. However, the lateral direction of the vehicle body, that is, the position in the direction indicated by the arrow B in FIG. 2, is not necessarily determined depending on the shape of the window opening 5. For this reason, the positioning structure is conventionally adopted at several points in the section indicated by X in FIG.

FIG. 5 shows a general positioning structure. As shown in the figure, in this structure, the inner panel 3 is provided with a pin hole 51, and the sash frame 2 is also provided with a pin hole 52 corresponding to the pin hole 51. Align these pin holes 51, 52 with the jig pin 5
Positioning was performed by inserting No. 3.

[0005]

However, the above-mentioned conventional positioning structure has the following drawbacks. (1) Since it is necessary to provide the pin hole 51 in the inner panel 3 and further to provide the pin hole 52 corresponding to the pin hole 51 in the sash frame 2, the cost tends to increase due to the increase in the number of processes. . (2) The pin holes 51 and 52 must be aligned with each other and the jig pin 53 must be inserted therethrough, which causes an increase in the number of working steps. (3) Water leakage may be caused by forming the pin hole 52 in the sash frame 2.

Therefore, an object of the present invention is to provide a positioning structure for a welded part of an automobile door which eliminates the above-mentioned pin hole to reduce the burden on the process and cost and eliminates the inconvenience such as water leakage. It is in.

[0007]

In order to solve the above problems, the invention according to claim 1 is a positioning structure for welding a welded component to a panel member constituting an automobile door, which includes the automobile door. It is characterized in that a bead shape running in a direction perpendicular to a plane is attached to the panel member.

According to a second aspect of the present invention, in the positioning structure for a welded part of an automobile door according to the first aspect, the panel member is an inner panel, and the inner panel has a window forming opening. A bead shape is attached, and the welded part is a sash frame.

[0009]

In the structure for locating the welded parts of the automobile door according to the first aspect of the present invention, the bead shape running in the direction perpendicular to the plane including the automobile door is attached to the panel member, which is conventionally required. Positioning is possible without using a pin hole, and the process and cost can be reduced.

According to the second aspect of the present invention, there is provided a welded part positioning structure for an automobile door, wherein the bead shape is attached to a portion of the inner panel forming the window opening portion to position the sash frame. It is not necessary to provide a pin hole in the sash frame, and water leakage from this part can be prevented.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows an automobile door 1 provided with a welding part positioning structure according to the present invention. The positioning structure according to the present embodiment is provided in the window frame portion 6 above the window opening portion 5 in the section indicated by X in the drawing.

Next, FIG. 2 is a sectional view taken along the line AA of FIG. 1, showing the positional relationship between the sash frame 2 and the inner panel 3. The sash frame 2 is welded to the inner panel 3 to form a reinforcing frame having a closed cross section in the window opening. That is, the sash frame 2 and the inner panel 3 form a partition space 4.

Further, in FIG. 2, 7 is a door glass,
8 is an upper molding and 9 is a glass run. The upper mole 8 has a function of sealing between the upper portion 10 of the door frame and the window frame portion 6, while the glass run 9 has a function of sealing between the door glass 7 and the window frame portion 6. And these functions are almost the same as the conventional ones.

Incidentally, in FIG. 2, the upper molding 8,
Although the elastic member such as the glass run 9 is drawn as if it interferes with other members, it is actually deformed by a rigid member such as the window frame 6 and the door glass 7 so as to maintain the sealing structure. There is.

3 and 4 show characteristic parts of the present invention.
FIG. 3 shows the window frame portion 6 so that the characteristic part of the present invention becomes clear.
It is shown by cutting a part of. As shown in FIG. 3, the present invention is characterized in that the inner panel 3 is provided with a bead 11 (beaded). The bead 11 is provided so as to run in a vertical direction or a substantially vertical direction with respect to a plane including the vehicle door 1. In this embodiment, the bead 11 is formed to have a semicircular cross section as shown in the figure.

As shown in FIG. 4, the bent end 2a of the sash frame 2 is in contact with the end 11a of the bead 11 in a welded state. In addition, in FIG. 3 and FIG.
Indicates the welding point.

In this embodiment, when welding the sash frame 2 to the inner panel 3, the position on the plane including the automobile door 1 is determined by the shape of the window opening 5 provided in the inner panel 3. On the other hand, at the position in the lateral direction of the vehicle body, that is, in the position shown by the arrow B in FIG.
It can be easily determined only by bringing it into contact with the end portion 11a of No. 1. As described above, the positioning can be performed without providing the pin hole which is conventionally required. Further, since the sash frame 2 is not provided with the pin hole, there is no possibility of water leakage from that portion.

Although the illustrated embodiment has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made to the shape of each component and the like. For example, in the above embodiment, the bead was formed as a semi-circular recess, but in short, if it determines the position in the vertical direction of the sash frame with respect to the plane including the automobile door, it performs the same function as the bead according to the present invention. be able to. Further, the number of beads to be provided can be appropriately determined according to design conditions. In addition to the above inner panel, the same structure can be adopted when welding other welded parts to other panel members used for automobile doors. Further, the welded parts welded to the panel member may be other than the sash frame.

[0019]

As is apparent from the above description, the above-described pin hole is not required to reduce the burden on the process and the cost, and the positioning structure for the welding parts of the automobile door which eliminates the inconvenience such as water leakage is provided. Can be provided.
