Problems solved by technology

In particular, when the vehicle is running at high speed, there is a problem that the window frame is sucked to the outside of the cabin under the action of negative pressure, and the sealing performance of the door is lowered.
In Patent Document 1, the rigidity is improved by pressing the window frame of the pillar portion on the front side in the vehicle longitudinal direction, but the problem of stress concentration at the base of the window frame portion remains unsolved.

no. 1 Embodiment approach

[0036] Figure 2 to Figure 5 A pillar window frame portion 2A of the front door 1F to which the door structure according to the first embodiment of the present invention is applied is shown. In the figure, the pillar sash portion 2A is composed of a sash outer reinforcement 21 and an inner reinforcement 22 joined to the interior of the vehicle compartment of the sash outer reinforcement 21, and the sash outer reinforcement 21 substantially serves as the center of the window frame 3A. The mounting portion has an expanding surface (21b) formed on the front side (opposite side to the door glass) of the window frame 3A in the vehicle front-rear direction.

[0037] The sash outer reinforcement 21 (and the inner reinforcement 22) includes: a pillar portion 21a positioned from a junction between the sash outer reinforcement 21 (and the inner reinforcement 22) and the roof side sash portion 2D. On the extension line of the extended roof side sash portion 2D, extending between the abo...

no. 2 Embodiment approach

[0048] Image 6 A pillar window frame portion 2C of the rear door 1R to which the door structure of the second embodiment of the present invention is applied is shown. exist Image 6 Among them, the pillar window frame portion 2C is constituted by joining a window frame outer reinforcement member 23 which serves as an attachment portion on the upper end side of the window frame 3C to an inner reinforcement member 24 disposed on the vehicle interior side of the window frame 3C. An expanded surface is formed on the rear side (the side opposite to the door glass) of the window frame 3C in the vehicle front-rear direction, and the expanded surface is welded by spot welding Wc. In addition, the window frame 3C is welded to the window frame outer reinforcement 23 at the lower end corner between the spot welding Wc and the outer reinforcement 4 ′ in addition to the upper end.

[0049] In the rear door 1R of this embodiment, the width of the pillar window frame portion 2C in the veh...

Abstract

The present invention provides a vehicle door structure capable of reliably increasing the rigidity of a base portion of a window frame portion with a simple structure. The inner reinforcement (22) is joined to the vehicle compartment inner side of the window frame outer reinforcement (21) supporting the window frame (3A), the lower part (22b) of the inner reinforcement is joined to the inner panel (12), and the inner reinforcement (22) And the window frame outer reinforcement (21) has an expansion surface (21b), which is formed on the side opposite to the door glass with the window frame (3A) as a reference, wherein the above-mentioned outer reinforcement (4) has an extension to The extension part (41) of the expansion surface is connected with the inner reinforcement part (22) through the extension part.

Description

technical field [0001] The present invention relates to a door structure for a vehicle, and more specifically, to a mounting structure for a window frame of a sash door with a door main body and a window frame that are independently configured. Background technique [0002] Conventionally, for doors with liftable glass, it is known from the characteristics of the structure that a window frame with the same cross-section formed by roll forming is attached to a main body of the door formed by stamping that securing the rigidity of the base of the window frame is basic question. In particular, when the vehicle is running at high speed, there is a problem that the window frame portion is sucked toward the outside of the vehicle compartment by negative pressure, and the sealing performance of the door is lowered. In Patent Document 1, rigidity is improved by pressing the window frame of the pillar portion on the front side in the vehicle longitudinal direction, but the problem o...
