Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an automobile door structure that improves the structure of the automobile door body.

[Technical background of the invention and its problems]

Generally, as a door attached to a car, a door body is formed by a door outer panel placed on the outside of the car body and a door inner panel placed on the inside of the car body, and these door outer panels and the door A housing part for housing the door window glass disposed at the top of the door body is formed between the inner panel and the door window glass is inserted into the housing part of the door body from the closed position where it closes the window part at the top of the door body. There is a known structure in which the device can be raised and lowered to a stored storage position. by the way,
The conventional structure had a problem in that the rigidity of the door body was relatively weak. Therefore, for example, when the car is running, the door body can be relatively easily bent due to negative pressure acting on the outside surface of the door window glass, and the door window glass may be pushed out to the outside of the car body. There was a risk of the noise being transmitted.

[Purpose of the invention] This invention increases the rigidity of the area around the door window glass opening in the door body, and prevents the door window glass from being sucked outward in the vehicle width direction by the negative pressure generated when the vehicle is running at high speed. It is an object of the present invention to provide a door structure for an automobile that can prevent the door outer panel around the opening for taking in and taking out the glass from being displaced outward, thereby reducing noise.

[Summary of the idea]

In this invention, a door body is formed by a door outer panel placed on the outside of the car body and a door inner panel placed on the inside of the car body, and a door is placed between the door outer panel and the door inner panel. A storage section is formed to accommodate a door window glass disposed in the upper part of the main body, and the door window glass is raised and lowered from a closed position where it closes the window section at the upper part of the door body to a storage position where it is stored in the storage section. In a possible automobile door structure, a first sash component is formed by slanting a portion of the window frame defining the window that exists in front of the vehicle body, and a front inclined portion of the first sash component a second sash component having one end fixed to approximately the middle portion and the other end extending into the housing portion;
A sash ring for reinforcing a window frame, which is disposed at the front end portion of the door body around the opening for taking in and taking out the door window glass, and between the first sash component member and the second sash component member. a hose, a rear end of the suction hose,
a flange portion formed to extend rearward than the second sash component; and an outer panel reinforcement hose attached to the inner surface of the door outer panel along a portion near the opening, and whose vertical cross section forms a closed cross-sectional shape. The front end portion of the outer panel reinforcement hose is further coupled to the flange portion of the suspension hose.

[Example of idea]

The drawings show one embodiment of this invention.
Figure 1 shows the appearance of a car body 1, and 2
is the front door and 3 is the rear door. In addition, FIGS. 2 and 3 show the door body 4 of the front door 2.
This shows the door body 4 of this front door 2.
is formed by a door outer panel 5 disposed on the exterior side of the vehicle body 1 and a door inner panel 6 disposed on the interior side of the vehicle body 1. Further, a housing portion 8 is formed between the door outer panel 5 and the door inner panel 6 to accommodate a door window glass 7 disposed on the upper part of the door body 4. This door window glass 7 can be raised and lowered from a closed position where it closes a window 9 in the upper part of the door body 4 to a housing position where it is housed in a housing section 8 of the door body 4. Further, as shown in FIG. 2, a suction hose 12 for reinforcing the window frame 11 is disposed at the front end of the door body 4 around the opening 10 for taking in and taking out the door window glass. In this case, the window frame 11 that defines the window portion 9 includes a first sash component 13 whose portion at the front of the vehicle body is inclined, and approximately midway between the front inclined portion of the first sash component 13. One end is fixed to the housing part 8 by means such as welding, and the other end is formed by a second sash component 14 extending into the housing part 8.

In addition, the sapling hose 12 is adapted to the shape of the opening formed between the first sash component 13 and the second sash component 14 of the window frame 11, as shown in FIGS. 4 and 5. It is formed into a shape. And this Satsushirinhose 1
2 is arranged to close the opening between the first sash component 13 and the second sash component 14 of the window frame 11, and the first sash component 1
3 and the second sash component 14 by spot welding. moreover,
A flange portion 15 extending rearward is bent at the rear end of the suction hose 12.

Further, on the inner surface side of the door outer panel 5 of the door body 4, an outer panel reinforcement 16 for reinforcing the door outer panel is arranged near the opening 10 of the door body 4 for taking in and taking out the door window glass. One end of the outer panel reinforcement 16 is fixed to the rear end of the door body 4 by spot welding, and the other end is fixed to the flange 15 of the suspension hose 12 by spot welding. A closed cross section in which an internal space 17 is closed is formed between these outer panel reinforcements 16 and the door outer panel 5.

Therefore, in the case of the above structure, the door body 4
A suction line hose 12 for reinforcing the window frame 11 is disposed at the front end portion around the opening 10 for taking in and taking out the door window glass.
Since the front end portion of the outer panel reinforcement 16 is connected to the flange portion 15 formed at the rear end portion, the rigidity of the door outer panel 5 around the opening 10 for taking in and taking out the door window glass of the door body 4 can be increased. Therefore, the door outer panel 5 around the opening 10 for taking in and taking out the glass passes through the door window glass 7 which tends to be sucked outward in the vehicle width direction by the negative pressure generated when the vehicle is running at high speed.
Since it can be prevented from bending in a state in which it is displaced outward, noise can be reduced compared to the conventional case.

It should be noted that this invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of this invention.

[Effect of idea]

According to this invention, a suspension hose for reinforcing the window frame is provided at the front end of the door body around the opening for taking in and taking out the door window glass, and a flange formed at the rear end of this suspension hose is attached to the outer panel link. By joining the front end of the hose, it is possible to increase the rigidity of the door outer panel around the opening for inserting and removing the door window glass in the door body, and the negative pressure generated when the vehicle is running at high speeds will be sucked out to the outside in the vehicle width direction. Through the door window glass, it is possible to prevent the door outer panel around the opening for taking in and taking out the glass from being displaced outward, thereby reducing noise.
