Abstract

PURPOSE:To prevent hissing sounds from occurring by arranging the general face of a wind panel and the car outside face of a wind sash along a smoothly continuing face in a window structure that the wind panel is raised or lowered along the window sash through a glass run. CONSTITUTION:The edge of a window panel 10 as a window glass is bent so as to incline from a panel general face 10a to the inside of a car compartment, and the wind panel 10 is guided up and down along a window sash 3 through a glass run 4 at its bent section 10b. Here, the window panel general face 10a and the car outside face 3a of the window sash 3 are arranged along a smoothly continuing face P by the existence of the bent section 10b, thereby the air current while the car is running flows smoothly along the smooth face, thus the cause creating hissing sounds is eliminated and the aerodynamics characteristics of the car can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window structure for an automobile, and more particularly to a window structure in which a wind panel is raised and lowered along a windshield via a glass run. Taking a door window as an example, looking at the relationship between a door sash shaped like a channel and in contact with the door body, and a door glass that is guided up and down by this door sash via a glass run, the door sash is located at the periphery of the door glass. In order to hold S, the outside surface of the door sash inevitably protrudes to the outside of the vehicle from the space between the door glass and the shell, and a step is formed.

This difference in level between the satchel surface and the glass surface disturbs the airflow when driving, causing air temperature to rise and causing wind noise.The turbulence in the airflow increases running air resistance and reduces running performance. This is well known.

In order to solve this problem, a glass guide offset in the width direction of the glass is glued to the periphery of the door glass, and this glass guide is guided up and down by the door sash via a glass run. A method has been proposed in which pressure is applied so that the space between the shells and the outside surface of the door sash is flush with the road surface, and the above-mentioned level difference is eliminated as much as possible.

However, with a structure in which the glass guide is bonded to the door glass like this, it is necessary to select a material for the glass guide that provides sufficient adhesive strength.
If a sufficient amount of adhesive is allowed between the glass guide and the door glass in order to stabilize the adhesive strength, the side visibility due to the door glass will be reduced, which is not good for safe driving, and it will feel strange as a window. There also arises the problem of deterioration in appearance quality.

This invention was made in view of the conventional situation,
The purpose of the present invention is to provide a window structure with good appearance quality, good wind noise and aerodynamic characteristics even if the glass guide is eliminated, and excellent lateral visibility.

In order to achieve such an object, the present invention bends the edge of a wind panel as a window glass so as to be inclined toward the passenger compartment side from the panel installation surface, and in this bending 11S, the wind panel is inserted through a glass run. The wind panel is configured to be guided up and down by the wind panel, and the wind panel installation surface and the outer surface of the window sash are arranged along a smooth continuous surface, so that the airflow during driving is disturbed along the smooth surface. The purpose is to improve the aerodynamic characteristics of the vehicle by eliminating the cause of wind noise and improving the aerodynamic characteristics of the vehicle.

Next, one embodiment of this invention will be described.

In Figures 1 and 2, t is the door, 2 is the door body,
3 is a door sash as a window sash, DA is a glass run for sealing fitted into the door sash 3, and S is a glass run installed on the door sash that forms the periphery of a single door opening. 10 is a door glass serving as a window panel, the edge of which is bent toward the inside of the vehicle from the general surface 1OIL, and this bent portion 10 b, it comes into elastic contact with the seal lip IIa, #a of the glass rank and is guided up and down.Then, the door sash 30 is connected to the outside surface 3a of the vehicle and the door glass installation surface 10a.
and are arranged along a smoothly continuous plane PK.

The visibility gap @Q between the door glass 10 and the glass rank depends only on the protruding chamber of the glass, and there is nothing that obstructs the visibility between the door glass io and the satsume 3 side. In addition, an example of the door sash JFi press door sash is shown, and the outer panel of the door body 2 is integrated with K1f.
Satsushauta, which was made into f1? 0, and 3 sash/sash molded integrally with the inner panel of the door body 2,
It consists of a U-shaped connector M that connects these outer and inner sashes 30 and 32 and forms a glass run holding member.

The connector 3It is connected to the bent portion of the door glass 10.
Is the bottom wall so that b and the glass rank can secure sufficient sealing performance? tta is formed so as to be approximately perpendicular to the glass bent portion 10b. With this configuration, the door glass faces the door sash 3 via the glass run so as to exhibit sufficient elevating and lowering guiding performance and sealing performance. Since the glass installation surface/□a and the outside thi3a of the door sash 3 are smoothly connected, there is little wind noise caused by turbulence in the airflow (indicated by arrows) during driving. At the same time, aerodynamic characteristics are improved, and fuel efficiency and other driving performance can be improved as well.

However, no matter what, the door glass 10 is not equipped with a separate part such as a glass guide as in the past, so visibility is primarily determined by the glass run IK on the door sash side into which the glass is fitted. Sarekiri 111
Q extends rearward, providing good visibility, and since there is no separate glass guide, there is no need to consider the glass guide material, adhesive, adhesive strength, etc., and productivity is excellent.

It should be noted that forming the bent portion 10b of the door glass 10 is fully possible with the current technological level, and if a transparent or semi-transparent acrylic plate is used as the window panel, the moldability is even better, and it is possible to form the bent part 10b of the door glass 10. Perfect for things.

As is clear from the above, according to the present invention, it is possible to obtain a window structure that is good in terms of wind noise and aerodynamic characteristics without having to attach any guide as a separate part to the wind panel. It is inexpensive, there is no need to take safety into account, and it is highly productive, with sufficient side visibility secured, and has great practical effects.
