Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sash structure for a full press door, and particularly to a full press door comprising a connecting member between a door outer panel and a door inner panel. Regarding improvement of the sash structure.

[Conventional technology]

Generally, as shown in FIG. 1, in a full press door D, a door outer panel and a door inner panel are press-molded into a predetermined shape in advance, and the door body 1 and the sash portion 2 are integrally formed by these door panels. This full press door D
The body shape is made smoother by minimizing the height difference between the body and the outer skin of the vehicle, and it is also designed to reduce air resistance and prevent wind noise when the vehicle is running (Sankaido version). (See page 125).

[Problem to be solved by the invention]

By the way, the sash section 2 in this type of full press door includes a door outer panel 31 and a door inner panel 3, as shown in FIG. 3, for example.
2 are hemmed together at their peripheral edge 30, while the door outer panel 31 and the door inner panel 3
On the inside of 2 is a connecting member 33 that connects the two by welding. In this type, the sash part 2 is equipped with a guide member 35 etc. that suppresses the suction phenomenon of the door glass 3 when the door glass 3 is closed. is generally formed, and the holding portion 39 of the guide member 35 etc. in the related art is, for example, a U-shaped portion attached to the connecting member 33 adjacent to the joining flange 38 between the connecting member 33 and the inner edge of the door outer panel 31. A channel portion 40 is formed.

By the way, from the viewpoint of improving rigidity, the sash section 2 in the conventional full press door of this type has a closed space 54 formed by the door outer panel 31, the door inner panel 32, and the connecting member 33.
There is a desire to increase the area by .

Therefore, it is possible to increase the dimension H of the closed space in the vertical direction, but increasing this dimension H would reduce the vertical dimension of the window opening below the sash, which is not preferable in terms of ensuring visibility of the window. Therefore, the closed space 54 is formed to bulge toward the interior of the vehicle, as shown by the imaginary line in FIG.

By the way, when the closed space is formed to bulge out in this way, it becomes difficult for the door weather strip 50 to come into contact with the vehicle body if the door weather strip 50 is attached to the position shown in FIG. A joining flange portion 52 formed by the door inner panel 32 and the joining member 33 is formed at the end of this closed space, and a door weather strip 51 is attached thereto.

However, when joining the joint flange part 52 in the sash part of such a full press door using a spot welder, the spot gun is affected by the presence of the protruding step part 53 of the door inner panel, making it difficult to perform the welding work. There's a problem.

SUMMARY OF THE INVENTION An object of the present invention is to facilitate spot welding work on the sash of a full press door and to provide sufficient welding strength.

[Means to solve the problem]

The gist of the present invention is that a door outer panel and a door inner panel are hemmed together at their peripheral edges, and a connecting member is fixed to the inner edges of the door outer panel and door inner panel to connect them. In the sash structure of a full press door, the door inner panel has a protruding step that protrudes into the vehicle interior, and a flange extending from the protruding step toward the interior of the vehicle, and a connecting member is joined to the flange. This joint flange and the protruding step portion constitute a door weather strip holding portion, and the opening angle of the door weather strip holding portion formed by the protruding step portion and the joining flange is expanded. The reason lies in that the joining flange is inclined in the opening direction.

〔Example〕

Embodiments shown in the accompanying drawings will be described in detail below.

In the embodiment shown in FIG. 2, the sash portion 2 of the full press door D includes a door outer panel 4 having a panel surface that smoothly connects to the vehicle body outer panel and door glass 3 (not shown), and a panel surface of this door outer panel 4. On the other hand, there is a door inner panel 7 having a protruding step portion 5 protruding toward the inside of the vehicle interior, and a flange 6 extending toward the inside of the vehicle interior at the end of the protruding step portion 5, and a substantially L-shape with a recessed portion 23 in the middle portion. It consists of a molded channel, and its both ends are spot welded to the inner circumferential edge flange 6 and the vicinity of the outer circumferential edge of the door inner panel 7, respectively, and the door outer panel 4
The end of the protruding portion 25 protruding to the side is composed of a reinforcement 10 which is a connecting member and is attached to the door outer panel 4 through an adhesive 26.

In this embodiment, a hemmed portion 11 is formed on the outer periphery of the door outer panel 4, and the outer periphery of the door inner panel 7 is clamped and fixed to the hemmed portion 11, so that the door outer panel 4 and the rainforth 10 are connected to each other. Thus, a closed cross-sectional space S is formed.

Further, a door weather strip holding portion 18 is formed in a channel shape by the protruding step portion 5 and flange 6 of the door inner panel 7 and the channel portion 9 of the rain force 10. Embosses 20 for positioning and bending flanges 21 are formed on both side walls constituting the door, and a door weather strip 19 is fitted into the door weather strip holding portion 18.

In this embodiment, the flange 6 of the door inner panel 7 and the portion of the reinforcement 10 that becomes the welding surface of the flange 6 are provided so as to be inclined toward the inside of the vehicle. In this embodiment, the guide member holding portion 13 is formed of an inner peripheral edge flange 22 of the door outer panel 4 and a protrusion 27 protruding into the recess 23 of the reinforcement 10. A glass run 15 is fitted as a guide member. Also, Satsushi Department 2
A closed cross-section space S' that is different from the closed cross-section space S is formed inside, which increases the substantial closed cross-section space of the sash section 2, increasing the rigidity of the sash section 2, and increasing the door resistance. The tensile rigidity of the outer panel 4 also increases.

Therefore, according to this embodiment, since the joint flange f between the rain force 10 and the door inner panel 7 is inclined in the direction in which the opening angle of the door weather strip holding part 18 widens, the spot welding work is not necessary. At times, the spot gun is not affected by the presence of the protruding step part 5 of the door inner panel 7, making it possible to easily carry out spot welding work and ensuring sufficient welding strength at the joining flange. Furthermore, when the joining flange f is viewed from the inside of the vehicle, the width of the joining flange f becomes narrower as the joining flange f is inclined, and the door thickness l at the sash portion 2 can be made thinner by that amount. This makes it possible to reduce the feeling of pressure on the occupants.

〔Effect of the invention〕

As explained above, according to the structure of the sash part of the full press door according to the present invention, it is possible to widen the opening end width of the holding part of the member attached to the sash part, and the insertion space for the spot gun is widened. This not only makes it easier to weld the joint flange forming a part of the holding part, but also allows the tip of the spot gun to be made larger to a certain extent, so that the welding strength of the joint flange can be increased to a sufficient level.
