Abstract

PURPOSE:To restrain the amount of deformation of a sash and prevent air from leaking by extending the front and rear ends of a rain hose and bonding these ends to said sash and an inner panel. CONSTITUTION:A sash 9 consists of an upper sash 23, around which a weather strip 21 is provided, and a lower sash 25 housed in a door body 5, and is erectly provided by means of welding, etc. to an inner panel 13 on the front and rear end sides of a retracting opening 17. A rain hose 27 is welded S1 and bonded P to the upper inside of an outer panel 11 in the longitudinal direction. The negative pressure generated around the door when running at a high speed acts as a suction force that sucks a window panel 7 outwardly, but the deformation of the sash 9 can be restrained small since it is supported by the inner panel 13 and the outer panel 11 through the rain hose 27, with the three parts being formed in one body. Thereby, the sealing function of the weather strip 21 can be secured preventing air from leaking.

Description

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

Conventionally, as shown in Figs. 1 to 3, a window glass d moves up and down on the upper end of a door body C consisting of an outer panel a and an inner panel b. A frontage e for advancing and retreating is provided E), and an opening e for advancing and retreating is provided.
A sash f supported by an inner panel b is erected at the front and rear ends of the sash f.

In a door structure with such a configuration, the negative pressure generated around the vehicle body during high-speed regular running is a suction force F that sucks the window glass d outward.
As a result, the satsush f deforms outward. During this deformation, the upper end of the boot shoe 1 undergoes a large amount of deformation using the root fixed to the periphery of the opening as a fulcrum, so the weather strip around the boot shoe (the weather strip around the boot shoe 1) becomes unable to function due to the seal, and air leaks out and is sucked out. It was causing the noise.

Therefore, in order to eliminate the deformation of Satsush f, for example, 1
Although it is conceivable to increase the rigidity by making the bush f itself thicker, this measure is not desirable from the viewpoint of energy saving and weight reduction. It is also possible to increase the welding surface at the base of the sash r, but since the end of the inner panel f is processed by the end of the outer panel a and the hemming 9, the inner panel b itself may be deformed (
(dashed line), and the rigidity was still insufficient.

Therefore, the object of the invention is to suppress the deformation of the sash to the extent that the weather strip provided around the sash functions as a seal, thereby eliminating air leakage.

In order to achieve the first objective, in this invention, an opening for advancing and retracting the window panel is provided at the upper end of the door body consisting of an outer panel and an inner panel. The gist is that a sash is erected, and the front and rear ends of a rain hose supported on the upper part of the outer panel are extended and connected to the sash and the inner panel.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 4 to 9.

FIG. 4 shows a four-door type automobile 1.

The door 3 of the automobile 1 has a door body 5, a window panel 7 (glass), and a shutter 9. The door body 5 has a box-shaped cross section with an outer panel 11 and an inner panel 13, as shown in FIG. It is shaped like.

The ends of the outer panel 11 and the inner panel 13 are processed by a hemming 15, and the upper ends are C-opened along the front and rear panel direction, forming an opening 17 for the window panel 7 to move forward and backward. The lower end of the window panel is supported by a window regulator 19 so as to be movable up and down.

On the other hand, the sash 9 is provided with a weather strip 21 (from the upper 23 and the lower sash 25 in the door body 5) to the inner panel 13 on the front and rear ends of the opening 17 for advancing and retracting. The rainport 27 is erected by means such as welding.Furthermore, a rainport 27 is welded S1 and WP in the front-rear direction on the inner upper part of the outer panel 11.The front end 29 of the rainport 27 is attached to the front end 27 as shown in FIG. As shown in FIG.
and are welded S3 and connected. Ma]ζ, Rainport 27
The rear end 33 is integrally connected to the inner panel 13 and the base end 35a of the portion 35 that fits into the center pillar of the CC ZARASH under the bell mill line W by welding or the like, as shown in FIG.

With the door structure constructed in this manner, the negative pressure generated around the door during high-speed driving acts as a suction force by sucking the window panel 7 outward, but the suction force is applied to the window panel 9 through the rain hose 27. Inner panel 13 and outer panel 1
Since it is supported by three parts (1), deformation can be kept small. This ensures the sealing function of the weather strip 21 and prevents air leakage. As a result, the sucking sound disappears.

As explained above, according to the door structure according to the present invention, the outer panel and the inner panel extend through the rainport to support the sash, and therefore the supporting rigidity of the sash can be greatly increased. This makes it possible to eliminate the problem of air leakage caused by air leakage.
