Description

[Detailed description of the invention] This invention relates to an improvement of an automobile door.

Conventionally, as shown in Japanese Utility Model Application Publication No. 55-165824, a triangular corner bracket has been attached to the part surrounded by the door sash and glass of an automobile, but this bracket cannot be connected to the door panel. It was not made firmly and contributed little to improving the rigidity of the door.

This invention was made to solve these conventional drawbacks, and provides a structure that allows the corner bracket to be firmly attached to the door panel and improves the rigidity of the front upper part of the door. It is something. That is, this invention is a door in which the door panel is formed by joining an inner panel and an outer panel, and a substantially horizontal flange is formed at the upper front joint portion of the inner panel and the outer panel. A corner bracket is located at the corner between the upper edge and the front part of the door sash, and a substantially horizontal flange is formed at the lower end of the corner bracket, and the flange of the corner bracket and the outer panel and inner panel are connected to each other. The flanges are stacked in three layers and fixed to each other by welding.

Embodiments of this invention will be described below with reference to the drawings. The front seat door 1 has a door panel composed of an outer panel 2 and an inner panel 3, and a door sash 4 is attached thereto, and a door glass 5 is held by the door sash 4 so as to be movable up and down. Further, a triangular corner bracket 7 is attached to the upper front side of the door panel and a portion surrounded by the door sash 4 and the glass 5.

The corner bracket 7 is, as shown in FIG.
It is formed into a triangular box shape by a pair of mutually parallel side plates 70, a hypotenuse plate 71 connecting them, and a bottom flange 72, and a protrusion 73 is formed on the hypotenuse plate 71. Further, a connecting plate 74 bent into a U-shape is attached to the rear end vertical portion of both side plates 70 by means such as welding.

As shown in FIG. 3, the front upper portions of the outer panel 2 and the inner panel 3 are extended and bent inward, and further bent downward, and the tip end is a flange 2 extending in the horizontal direction.
0 and 30, and these are overlapped with each other to form a recess. A corner bracket 7 is fitted into this recess, and its flange 72 is stacked with the flanges 20 and 30 in three layers and welded to each other. Further, at the upper end of the recess, the upper end of the outer panel 2 and the side plate 70 of the corner bracket are brazed (brazed portion 75). Further, the oblique side portions 71 of the corner brackets 7 abut against the inner edge of the door sash 4, and the protrusions 73 are fitted into corresponding recesses, thereby being connected to each other.
The outer surface of the corner bracket 7 is covered with an anti-corrosion coating 76, and a garnish 77 is further attached to the surface on the inside of the vehicle.

As shown in FIG. 2, a launch channel 50 is fitted into a connecting plate 74 on the vertical side of the corner bracket 7, and the glass 5 is slidably held by this launch channel 50. Further, a front pillar 13 is located on the front side of the door 1, a front window 15 is adhesively fixed to this front pillar portion, and a molding 14 is attached to the outside thereof. Further, a pillar trim 16 is attached to the inside of the front pillar 13. A weather strip 8 is attached to the outer periphery of the door sill 4.
A seal is created by press-fitting this to the front pillar 13 and the like.

In Figure 2, the corner bracket 7 is attached to the door mirror 9.
An example is shown in which the operating lever 91 is passed through the corner bracket 7 to the inside of the vehicle, and the screw 90 is attached to the corner bracket 7.
By tightening, the door mirror 9 is fixed to the corner bracket 7.

In this embodiment, the flanges 20 and 30 are joined to the front upper part of the door panel, and the flange 72 of the corner bracket is welded in three layers, so that the corner bracket 7 is firmly connected to the door panel. This greatly improves the strength of the front part of the door. Furthermore, corner bracket 7
is fitted into the recess of the door panel, and the protrusion 73 on the oblique side is fitted into the door sash 4, so that it is firmly held by both.
Therefore, when the door mirror 9 is attached to the corner bracket 7, the door mirror 9 is stably held and does not resonate due to the vibrations of the vehicle. Note that the recessed portion of the door panel and the protrusion 73 of the corner bracket 7 do not necessarily have to be provided.

As explained above, this invention allows the corner bracket to be firmly attached to the door panel, thereby improving the rigidity of the front portion of the door.
