Description

[Detailed description of the invention] This invention relates to an automobile door structure, and in particular to an automobile door structure suitable for use in a so-called flat surface type automobile in which the outer surface of the vehicle body and the door glass surface are flush with each other. .

Air resistance when a car is running at high speeds can be more than double the rolling resistance.

For this reason, so-called flash surface type automobiles have been proposed in which the surface of the vehicle body, including the surface of the door glass, is made flush with the surface of the vehicle in order to reduce air resistance.

In the door structure of such a flat surface type automobile, the outer surface of the door glass and the outer surface of the door frame must be approximately flush with each other when the door glass is fully closed. When the vehicle is running at high speed, the door glass is sucked out to the outside due to the pressure difference between the inside and outside of the vehicle, and if the door glass lifts outward from the outer surface of the door, it not only causes so-called wind noise but also increases air resistance while driving. There is a problem with making it happen.

To address these problems, for example,
As described in Publication No. 158321 (see Fig. 2), a door glass piece 2 having a substantially crank-shaped cross section with a tip 2A offset toward the passenger compartment 3 is attached to the end 1A of the door glass 1. , the sliding portion 2A of the door glass piece 2 is inserted into the door glass 1 by the guide groove 5 on the door frame 4 side.
A vehicle that is slidably guided in the opening/closing direction, thereby bringing the outer surfaces of the door glass 1 and the door frame 4 flush with the road surface and preventing the door glass 1 from being sucked out. A door structure is proposed.

The reference numeral 6 in the figure is a sealing rubber that is placed in the guide groove 5 and also serves as a guide that comes into contact with the tip 2A of the door glass piece 2. 7 is a center pillar, 8 is a door weather strip, 9 is a frame molding, and 10 is a door door. Each door panel welded to the frame 4 is shown.

In the above-mentioned automobile door structure, it is possible to prevent the door glass 1 from being largely sucked outward, but the sliding portion 1 of the door glass 1
Seal rubber 6 for guiding A in the vertical direction
Since the door glass 1 must be elastically contacted to seal between the door glass 1 and the door frame 4 when the door glass 1 is opened and closed, it is elastically deformable in the thickness direction of the door glass. However, when the door glass 1 is fully closed, it is weakly held in the glass thickness direction, and the ability to prevent the door glass from being sucked out is not necessarily sufficient, and there is also the problem that rattling occurs.

On the other hand, it is possible to replace the seal rubber 6 with a hard material to prevent rattling of the door glass 1, but this would impair the sealing function and the operability of opening and closing the door glass. This causes many problems.

Further, for example, as described in West Germany Patent Publication No. 2809721 (see Fig. 3), a guide groove 5 integral with the door frame 4 is formed at the end 1A of the door glass 1 on the passenger compartment 3 side. and a slide piece 11 attached to the back side of the end of the door glass 1 (on the passenger compartment 3 side)
There is one in which the guide groove 5 is slidably projected in the vertical direction and engaged with the guide groove 5, thereby reducing rattling in the thickness direction of the door glass 1.

However, in this case, the seal between the door glass 1 and the door frame 4 is at the end 1A of the door glass 1.
Door glass weather strip 12 that contacts the corner
The outer peripheral surface 12A of the door glass weather strip 12 and the outer surface 4A of the door frame 4 on the outer peripheral side of the door glass weather strip 12 are 1, the portion of the door glass weather strip 12 that contacts the outside surface of the door glass 1 is small, and in order to make the door frame portion appear narrower, Since the width of the door glass weather strip 12 is also small, it is not possible to provide a sufficient seal between the door glass 1 and the door frame 4, and the contact of the door glass weather strip 12 to the door glass is also limited to increase the sealing function. If the pressure or the outer circumferential surface 12A were increased, there were problems in that the door glass 1 could not be opened and closed smoothly or that it would not be possible to make it flush.

This idea was made in view of the above problems, and aims to prevent the rattling of the door glass without impairing the sealing function and operability of opening and closing the door glass, and to achieve flushing. The purpose of the present invention is to provide an automobile door structure that enables the following.

This invention consists of a door glass piece that is attached to the edge of the door glass and has a substantially crank-shaped cross section with its tip sliding portion offset toward the passenger compartment; a sealing member that slidably contacts the door glass from both sides in the door glass thickness direction in the door glass opening/closing direction and seals between the door frame and the door glass piece;
A slider is attached to the door glass at a position closer to the center of the door glass than the door glass piece so as to protrude toward the vehicle interior, and the slider is integrally formed with the door frame and guides the slider in the door glass opening/closing direction. Also, via the slider,
A guide for regulating the position of the door glass at least in the thickness direction is provided, thereby separating the guide portion and the sealing portion of the door glass, impairing the sealing function and the operability of opening and closing the door glass. The above object is achieved by preventing rattling of the door glass.

Embodiments of the present invention will be described below with reference to the drawings.

In this embodiment, the same or equivalent parts as in the conventional automobile door structure shown in FIGS. 1 to 3 are given the same reference numerals as in FIGS. 1 to 3, and the explanation thereof will be omitted. shall be taken as a thing.

As shown in FIG. 4, this embodiment includes a door glass piece 2 which is attached to an end portion 1A of a door glass 1 and has a substantially crank-shaped cross section with a tip sliding portion 2A offset toward the passenger compartment 3 side. A seal that is arranged on the door frame 14 side, contacts the sliding portion 2A of the door glass piece 2 from both sides in the door glass thickness direction so as to be slidable in the door glass opening/closing direction, and seals between the door frame 14 and the door glass piece 2. member 16, and the door glass 1 at a position closer to the center of the door glass 1 than the door glass piece 2.
A slider 17 is attached to protrude toward the passenger compartment 3 and is formed integrally with the door frame 14, and guides the slider 17 in the door glass opening/closing direction, and via the slider 17,
A guide 18 for regulating the position of the door glass 1
and are provided to constitute an automobile door structure.

The sliders 17 are arranged at a total of three locations, the upper and lower ends of the rear end 1A of the door glass 1, and the front end, and each of the sliders 17 is arranged at three locations, as shown in FIG.
Bolt 17A protruding from the slider 17 side,
A nut 17B, which penetrates through the hole 1B from the front side of the door glass 1 and is screwed into the bolt 17A, is screwed onto the bolt 17A, and is tightened and fixed to the door glass 1 via a filler 19.

The tip of the slider 17 in the three directions of the vehicle interior is a head 17C with an enlarged diameter, and the guide 18 is
The head portion 17C of the slider 17 is slidably fitted in the door glass opening/closing direction and has a substantially upward C-shaped cross section, and is continuous with the guide groove 15 and the channel portion 8A for supporting the door weather strip 8. It is formed by integrally roll-forming a plate material.

Reference numeral 20 in the figure indicates the vehicle compartment 3 of the door frame 14.
The garnish covering the sides is shown.

The sealing member 16 includes a lip 16A that is enclosed within the guide groove 15 and contacts the slide portion 2A from the front and back sides in the thickness direction of the door glass.
It is equipped with 16B.

The lip 16B on the compartment 3 side of this seal member 16 is formed long between the guide groove 15 and the guide 18, thereby increasing the length of contact with the slide portion 2A. There is.

In this embodiment, the door glass 1 is firmly guided and held by the guide 18 on the door frame 14 side via the slider 17, so that the door glass 1 is not displaced outwardly when the car is running at high speed. In addition to reliably preventing the generation of wind noise, the sealing member 16 can be made of a sufficiently flexible material since it is not necessary to guide the door glass piece 2, and the door glass piece 2 has a low sliding resistance with the sealing member 16. Therefore, separation from the door glass 1 or wobbling can be prevented.

Further, since the sealing member 16 does not need to guide the door glass piece 2, it can be set with sufficient deflection in the direction of the thickness of the door glass.
Therefore, sealing performance can be improved.

Also, when the door glass 1 is raised or lowered, the seal member 16
Since no excessive force is applied to the door glass 1, the door glass 1 can be operated smoothly.

Furthermore, since the bending allowance of the sealing member 16 in the glass thickness direction can be set sufficiently, variations in the positional relationship between the door glass piece 2 and the slider 17 during manufacturing can be avoided, and the opening/closing operability of the door glass 1 and the sealing member 16 can be adjusted to a sufficient degree. can be absorbed without impairing the sealing performance.

Next, a second embodiment of the present invention shown in FIG. 5 will be described.

This second embodiment is similar to the first embodiment shown in FIG.
The attachment part of the door glass piece 2 to the door glass 1 in the embodiment is formed with an extension part 2B extending in the direction of the center of the door glass 1 along the side surface of the vehicle compartment 3 of the door glass 1, and this extension part 2B are fixed together with the end portion 1A of the door glass 1 using bolts 17A and nuts 17B of the slider 17.

This embodiment has an advantage over the first embodiment shown in FIG. 4 in that the door glass piece 2 can be firmly fixed to the door glass 1.
