Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a vehicle door structure adapted to a flush surface.

[Conventional technology]

2. Description of the Related Art In recent years, in vehicles, particularly automobiles, in order to improve aerodynamic characteristics, a so-called flush surface has been developed in which steps are removed as much as possible from the outer surface of the vehicle body. As a configuration for realizing this flush surface, as disclosed in Japanese Utility Model Application Publication No. 114012/1983, a door glass that can be raised and lowered is placed on the outside of the door sash extending upward from the door body. Some systems are known that use this method.

In the above door structure, since the door sash is located inside the vehicle, care is taken not to spoil its appearance, and a guide mechanism is used to guide the door glass so that the door glass can move up and down smoothly. is attached. This door glass guide mechanism utilizes a flange portion of a door sash and is comprised of this flange portion and a guide shoe provided on the inner surface of the door glass so as to slide along the flange portion. Further, the space between the door glass and the door sash is sealed by a weather strip that is separately provided on the door sash.

[Problem to be solved by the invention]

However, in the above-mentioned conventional structure, since the door sash requires a flange portion, a garnish that covers the flange portion is required to maintain the aesthetic appearance. Further, it is necessary to fix the guide shoe to the inner surface of the door glass. In addition, to attach the guide shoe to the door glass, a stopper member is used that penetrates the door glass from the outer surface of the door glass and engages with the guide shoe in order to obtain sufficient installation strength. Therefore, this stopper member is exposed on the outer surface of the door glass, detracting from its aesthetic appearance. Furthermore, the weather strip provided along the door sash to provide a seal between the door glass and the door sash is made of flexible material and is easily deformed, which also causes problems such as spoiling the aesthetics. have. Furthermore, there is a relatively large gap between the guide shoe and the door sash, which causes wind noise generated during driving to easily enter the vehicle interior, resulting in problems such as impairing the quietness of the vehicle interior. In addition, the aesthetic appearance around the corners formed by the door sash and the door body is insufficient, and a structure for improving this is required.

[Means to solve the problem]

In order to solve the above-mentioned problems, the vehicle door structure of the present invention has a door glass that can be elevated on the outside of the vehicle of a door sash that forms a window space above the door main body, and a door sash that can be used as a door glass. In a vehicle door structure in which a weather strip is provided for sealing between the glass and the door body, and a corner bracket is provided at the corner portion formed by the door sash and the door body at the end portion of the door body, the above-mentioned The weather strip has a part that wraps around from the inner peripheral edge of the door glass to the outer peripheral edge,
A core material is embedded in this part to form a glass guide part, while the front part of the door sash is bent along the rear edge of the corner bracket and extends downward.

[For production]

According to the above configuration, the weather strip has a core material embedded in the glass guide portion to increase rigidity, and thus has a door glass guiding function and a sealing function. Thereby, the door glass can be guided by the glass guide portion of the weather strip and perform a rising motion. Therefore, there is no need for a separate guide mechanism for the door glass, and this guide mechanism also eliminates the problem of unsightly appearance. Further, since the weather strip has a core material disposed in the glass guide portion, it is difficult to deform, and this also improves the appearance.

In addition, as mentioned above, the weather strip guides the door glass and seals the door glass and door sash without providing a separate guide mechanism, so when the door glass is closed, the door glass and door sash are sealed. There are few gaps formed between the two, making it difficult for wind noise generated during driving to enter the vehicle interior.

In addition, since the front part of the door sash is bent along the rear edge of the corner bracket and extends downward, continuity of the door sash at the rear edge of the corner bracket is achieved, making the corners particularly aesthetically pleasing. is improved.
