Description

[Detailed explanation of the idea] (a) Industrial application fields This invention relates to an automobile door.

(b) Prior Art Conventionally, this type of automobile door structure has been known as shown in FIGS. 4 and 5 (see Japanese Utility Model Application Publication No. 11225/1983).

Door window opening periphery 2 formed by door panel 1
A glass run 5 having a substantially U-shaped cross section is attached to the groove 3, which comes into contact with the periphery 4a of the door glass 4 as a window panel when the periphery 4a of the door glass 4 is fitted into the groove 3. . The glass run 5 is formed with an inner lip 5a and an outer lip 5b that sandwich and seal the peripheral edge 4a of the door glass 4.

In addition, the outer flange portion 6 of the groove portion 3 includes:
A molding 7 is fitted to cover the flange portion 6. The member designated by number 8 is a door weather strip that seals the door panel 1 and the vehicle body 9.

The configuration of this prior art is not limited to the type in which the door window opening periphery 2 is formed by the door panel 1 described above, but is also applied to a type in which the door window opening periphery is formed by a door sash.

(c) Problems to be solved by the invention However, in the case of such a conventional door, the outer surface of the molding 7 is There is a problem in that the step dimension L from 7a to the outer surface 4b of the door glass 4 becomes large, and wind noise is more likely to be generated during driving, and aerodynamic characteristics are also deteriorated.

This invention was made in view of these conventional problems, and aims to reduce wind noise and improve aerodynamic characteristics.

(d) Means for Solving Problems In order to achieve the above object, this invention installs a glass run having an inner lip that comes into contact with the inner surface of the window panel in the groove at the periphery of the door window opening, and attaches a glass run to the outer flange of the groove. A molding comprising a main body made of a hard member having a substantially U-shaped cross section and covering the flange portion, and a soft member provided on at least an inner piece of the main body, which cooperates with the inner lip to hold the window panel. The soft member is fitted with a folded part that intervenes between the inner piece and the outer flange part, and an outer lip that cooperates with the inner lip to seal the window panel is provided. do.

(e) Effect With this configuration, the outer lip protruding from the soft member of the molding works together with the inner lip of the glass run to hold and seal the window panel from the inside and outside, so there is no need to provide an outer lip on the glass run, and the outer lip of the molding It is possible to significantly reduce the height difference between the window panel and the outer surface of the window panel, thereby reducing wind noise while driving and improving aerodynamic characteristics.

Moreover, since the reaction force exerted on the window panel by the outer lip is small, the sliding resistance when the window panel is raised and lowered can be reduced, and smooth raising and lowering performance can be ensured. Furthermore, it is possible to effectively suppress the flapping of the window panel when the door is opened and closed, and it is also possible to prevent banging noise. Furthermore, since the main body of the molding has a substantially U-shaped cross section and has elasticity, it can hold the window panel. Furthermore, since the soft member is provided with a folded portion that intervenes between the inner piece and the outer flange, rusting due to contact between the inner piece and the outer flange can be prevented.

(f) Embodiment In FIG. 1, a door D according to this embodiment has an outer panel 10 integrally molded with the outer panel of the door body, and an inner panel 12 integrally molded with the inner panel of the door body. However, the terminal portion of the outer panel 10 and the terminal portion of the inner panel 12 are connected by hemming 14.

A channel plate 16 that holds the door weather strip 8 is welded to the outer periphery of the shelf 12a of the inner panel 12, and a bottom 18a of a U-shaped frame 18 is welded to the inner periphery of the shelf 12a. Flange 1 on the outside of this frame 18 (in the vehicle width direction)
8b is welded to the outer panel 10. Thus, the outer panel 10, the inner panel 12, and the frame 18 constitute a groove 20 at the periphery of the door window opening.

This groove 20 has a base 22 and a base 22.
A leg piece 23 extending from the terminal inside (in the vehicle width direction)
and an inner lip 24 extending outward from the end of the leg piece 23.
is installed. Specifically, the base 22 is fitted into the frame 18 , the end of the inner panel 12 is fitted into the end of the leg piece 23 , and the inner lip 24 is fitted into the base 22 .
is the inner surface 30a of the door glass 30 as a window panel
is in contact with.

The outer flange portion 32 of the groove portion 20 (formed by the flange 10a of the outer panel 10 and the flange 18b of the frame 18) has this flange portion 32.
A molding 34 is fitted to cover the.

The molding 34 consists of a main body 36 made of a hard material such as stainless steel and having a substantially U-shaped cross section, an end cap 38 covering the end of the outer piece 36a of the main body 36, and a central portion from the end of the inner piece 36b of the main body 36. The outer lip 42 is provided with a protruding outer lip 42 that contacts the outer surface 30b of the door glass 30 and cooperates with the inner lip 24 to seal the door glass 30. has been done. A folded part is provided between the inner piece 36b and the outer flange part 32 of the soft member 40, and the soft member 40 having the folded part is made of a resin material such as soft vinyl chloride. The cap 38 and the stainless steel main body 36 can be co-extruded. Alternatively, the end cap 38 can be formed as a separate piece and fitted later.

The outer surface of the main body 36 of the molding 34 (the outer surface of the outer piece 36a) and the general surface of the outer panel 10 are substantially smoothly continuous. As shown in FIG. 2, the molding 34 is integrally provided with a lip 50 protruding from the end cap 38 in a direction opposite to the fitting direction of the molding 34, so as to further ensure that the molding 34 is prevented from falling off. You can also. Further, as shown in FIG. 3, a drop-preventing lip 52 may be provided to protrude from the middle of the outer piece 36a of the main body 36.

With this configuration, the door glass 30 is held and sealed by the cooperation of the inner lip 24 of the glass run 26 and the outer lip 42 of the soft member 40, so there is no need to provide the glass run with an outer lip 5b (see FIG. 5) as in the conventional case. As a result, the step L between the outer surface of the molding (the outer surface of the outer piece 36a) and the outer surface 30b of the door glass 30 can be significantly reduced, reducing wind noise while driving and making the vehicle more flush, resulting in improved aerodynamics. Properties can also be improved.

In addition, since the outer lip 42 is formed into a J-shaped tongue with the soft member 40, the pressing force when it comes into contact with the door glass 30 can be reduced, so the reaction force against the door glass 30 can be reduced. , the sliding resistance when the door glass 30 is raised and lowered can be reduced, and smooth raising and lowering performance can be ensured. (In other words, the operating force of the door glass raising/lowering regulator mechanism can be made light.) Furthermore, it is possible to reliably suppress the door glass 30 from flapping and making banging noises when the door is suddenly opened and closed.

In addition, although the embodiment shows a so-called press door in which the window opening peripheral portion is integrated with the door panel, the present invention can be similarly applied to a roll-formed door sash.

(g) Effects of the invention As described above, this invention has the practicality of reducing wind noise during driving and improving aerodynamic characteristics without compromising liftability or vibration prevention. It can be highly effective.
