Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a back door of an automobile.

[Prior Art] Generally, a back door of a passenger vehicle or a commercial vehicle has a structure in which an inner panel having an upper window frame and an outer panel are joined by spot welding or the like, and the outer periphery of the wind glass is fitted into the wind frame via a weather strip. It is taken.

In this case, the inner panel and the outer panel are press-molded, but since these panels have a wind frame integrally, the press mold becomes large, and the joints of both panels are accurate, rust-proof, and safe. Since a complicated shape is required from the viewpoint of etc., many pressing processes are required,
There was a problem with equipment cost and workability.

Also, the door panel body and the wind frame are separated,
Although attempts have been made to connect both ends of the frame to the door panel body, the wind frame needs to have a shape that exactly matches the window opening of the body, and both ends of the window frame having a complicated cross-sectional shape are attached to the door panel body. The workability for manufacturing is not necessarily good because a process for joining is required.

[Problems to be Solved by the Present Invention] The present invention has been made in view of the above circumstances, and it is possible to reduce the cost by not requiring a large press die and to reduce the cost by not requiring a wind frame having a complicated sectional shape. Another object of the present invention is to provide a back door for an automobile having improved manufacturing workability, thereby solving the conventional problems.

[Means for Solving the Problems] The present invention is a wind frame in which the lower half portions of both legs of a wind frame, which is separate from the door panel formed in the inverted U shape, are fixed to the inner surface of the door panel and project above the door panel. The windshield is fixed to the outer surface of the upper half of the above so that the upper half of the windshield is along the outer periphery of the wind glass.

[Effect] Since the door panel and wind frame are separate, a large press die is not required. Further, since the wind frame is not of a glass fitting type and has a structure in which glass is fixed to the outside thereof, a complicated cross-sectional shape is not required and, for example, a pipe can be used. Further, the wind frame does not have to have a shape that matches the door opening of the body as in the conventional case, which greatly contributes to improvement in productivity and cost.

[Embodiment] FIGS. 1 to 3 show an embodiment of the present invention. The back door 2 has a hinge 4 at the rear door opening of the van-type automobile body 1.
Are combined by.

The back door panel 3 is formed by welding the outer panel 3a and the inner panel 3b at the outer peripheral portion thereof. The wind frame 6 is a pipe material molded into a U shape.
It is arranged in an inverted U-shape position, and the lower halves of both legs are fixed to both side portions of the inner panel 3b. That is, as shown in FIGS. 1 and 2, a bracket 7 is fixed to the leg portion in advance by welding or the like, and the inner panel 3b is fixed to the bracket 7.
Are fixed with bolts 8a and nuts 8b.

The upper half of the wind frame 6 projects above the back door panel 3, to which the wind glass 5 is fixed from the outer surface side. That is, as shown in FIGS. 1 and 3, brackets 10 whose ends extend like arms are fixed to the upper half of the wind frame 6 in advance by welding or the like. The bracket 1 is provided on the outer periphery of the windshield 5.
A hole is formed at a position corresponding to 0, and the bolt 11 is inserted into the hole of the bracket 10 from this hole and the nut 12 is tightened to fix the window glass 5 to the wind frame 6 via the bracket 10. . In addition, bolt 1
Cushion rubber 13 is provided between the head of 1 and the window glass 5, and between the bracket 10 and the window glass 5.
a and 13b are interposed. Reference numeral 14 is a cap that covers the nut 12.

As shown in FIGS. 1 and 2, a weather strip 9 is attached to the lower edge of the door glass 5 and is fixed to the upper edge of the back door panel 3 via the weather strip 9. The hinge 4 is a wind frame 6
It is fixed to the upper side of the.

As shown in FIGS. 1 and 3, a weather strip 15 is mounted around the door opening of the automobile body and comes into contact with the outer periphery of the window glass 5 to perform a sealing action when the back door is closed.

Therefore, in the above back door, the press die can be made smaller than the door panel integrally provided with the wind frame. In addition, the wind frame is pipe-shaped, so it is easier to manufacture than the conventional glass-embedded wind frame, and it is not necessary to have a shape that perfectly matches the door opening of the body, which is extremely advantageous in terms of productivity and cost. Is. Further, unlike the conventional wind frame, it is not necessary to provide a weather strip along the frame, and only the lower edge of the glass is required for the weather strip. Further, the glass surface can be made wider than that of the conventional glass fitting type in the frame.
