Description

  The present invention relates to a vehicle door structure including a window frame (sash) for guiding a movable window glass at an upper portion of the door.

  In recent years, sashed doors having a window frame (sash) for guiding a movable window glass provided above the door body tend to be employed in vehicle doors from the viewpoint of ensuring the rigidity of the vehicle body. For example, a sash formed on a front door has a main sash that extends from the front edge of the upper edge of the door body along the door opening, and a pair of front and rear auxiliary sashes that extend in the vertical direction. The upper end portion of the sash is connected in the middle of the main sash, and the upper end portion of the rear auxiliary sash is connected to the rear end portion of the main sash to constitute a main part. Furthermore, in this type of sash, gussets, mirror brackets, etc. are generally attached by welding or the like to the front area (corner corner) surrounded by the upper edge of the door body, the main sash, and the front auxiliary sash. Thus, the rigidity of the front auxiliary sash is improved (see, for example, Patent Document 1).

  By the way, in recent vehicles, the front pillar tends to be disposed closer to the front of the vehicle body for the purpose of expanding the cabin living space and improving the design. In such a case, the front part of the main sash is also shifted toward the front of the vehicle body. As a result, the area of the corner portion formed between the main sash and the front auxiliary sash is enlarged, and there is a possibility that the occupant's field of view may be hindered. Therefore, in this type of vehicle door, an auxiliary window portion (so-called triangular window portion) is formed by fitting a fixed window glass at a corner portion instead of a gusset or the like, thereby improving the occupant's visibility. May be planned.

  However, it is common that the window glass is fitted to the corners by fitting. Therefore, when the window glass is arranged at the corner corner, the rigidity of the auxiliary sash may be lowered as compared with the case where the gusset is arranged at the corner corner. When the rigidity of the auxiliary sash is lowered, the auxiliary sash is bent by a negative pressure or the like during high-speed traveling, and there is a possibility that wind noise or the like is generated.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle door structure capable of ensuring both the occupant's field of view and the auxiliary sash's rigidity with a simple configuration.

A vehicle door structure according to an aspect of the present invention includes a main sash extending from one end of an upper edge portion of a door main body, and an upper end portion of the door main body that extends in the vertical direction and is connected to the middle of the main sash. An auxiliary sash, a fixed window glass fixed in a region surrounded by the upper edge of the door body, the main sash and the auxiliary sash, and an upper edge of the door body in the region A front-rear extending portion that extends along the auxiliary body and joins the auxiliary sash and a vertical extending portion that extends along the auxiliary sash and joins the auxiliary sash are integrally formed in a substantially L shape in side view. The reinforcement is folded toward the outside of the fixed window glass at an edge portion on one side in the vehicle width direction of the front and rear extension portion and the vertical extension portion. A series of bent outward flanges A series of inward flange portions that are bent toward the inside of the fixed window glass at the edge of the other side in the vehicle width direction of the front and rear extension portions and the vertical extension portion. The cross section has a substantially crank shape, and the front / rear extending portion is joined across the inner panel and the outer panel constituting the door body via the flange portions.
