Description

  The present invention relates to a vehicle door structure including a door sash and a door glass that can be raised and lowered along the door sash.

  In a general vehicle door structure, a glass run as a sealing material is provided between a door glass and a door sash. The glass run has a groove into which an edge of the door glass is inserted, and the door glass is configured to move up and down while being guided by the groove. The glass run is made of a flexible resin material, and prevents rainwater or the like from entering the vehicle interior by contacting the door glass. Since this glass run is rich in flexibility, it may be deformed by being pressed by the door glass. Therefore, for example, in Patent Document 1, a member called a stopper member is provided between the door sash and the glass run, and the glass run is supported by this stopper member to suppress the deformation of the glass run.

  The glass run has a portion called a seal lip or the like that curves and extends toward the door glass. Since this seal lip can be bent, it does not interfere with the raising and lowering operation of the door glass while in contact with the door glass, and even if there is a slight error in the arrangement of the door glass, the error will not occur. It has an acceptable structure. However, for example, in the portion of the glass run outside the door glass (the vehicle outer portion), the seal lip projects greatly from the base toward the door glass, and the overall size of the vehicle outer portion is large. In addition to increasing the air resistance during travel, it may cause wind noise.

  In view of such a problem, an object of the present invention is to provide a door structure capable of preventing the generation of air resistance and noise by suppressing the thickness of the glass run with respect to the door glass.

  In order to solve the above problems, a typical structure of a door structure according to the present invention is a vehicle door structure including a door sash and a door glass that can be raised and lowered along the door sash, and the upper side of the door sash. A glass stopper that interferes with the upper edge of the door glass and regulates the rise of the door glass, and a flexible glass run that is attached to the door sash so as to be interposed between the glass stopper and the door glass. The glass run has a vehicle inner portion that contacts the vehicle inner surface of the door glass, an upper portion that contacts the upper end surface of the door glass, and a vehicle outer portion that contacts the vehicle outer surface of the door glass. Furthermore, it is continuous with the glass stopper inside the car and interferes with the inside part of the glass run. Characterized in that it comprises a kick side stopper portion.

  According to the above configuration, since the side stopper portion presses the door glass against the outside portion of the glass run, the outside portion of the glass run is compressed, and the outside portion of the glass run protrudes from the outside surface of the door glass. The degree of becomes smaller. Therefore, it is possible to suppress the generation of air resistance and wind noise during traveling.

  The interior portion of the glass run has a vertical wall portion extending vertically and a seal lip portion that extends upward from the lower end of the vertical wall portion on the door glass side and contacts the door glass. A region above the seal lip portion in the vertical wall portion may be pushed and bent. This is because this configuration does not affect the sealing performance of the seal lip and does not hinder the lifting and lowering operation of the door glass.

  The glass run may further include a protruding portion that protrudes so as to interfere with the door glass toward the door glass side in a region above the seal lip portion in the vertical wall portion. By providing this projecting portion, it is possible to suitably exert the pressing action of the side stopper portion against the outside portion of the door glass.

  Said side stopper part is good to incline so that a surface contact may be carried out to the vehicle inner side part of a glass run, and a door glass is pushed to the vehicle outer side part, so that it goes upwards. This makes it possible to more suitably press the door glass against the outside portion of the glass run when the door glass is closed.

  The surface on the door glass side of the protruding portion of the glass run is preferably parallel to the side stopper portion. Thereby, it becomes possible to more suitably exhibit the pressing action of the door glass against the outside portion of the glass run of the door glass.

  Said glass stopper and side stopper part are good to be provided in the vicinity of the side of a door sash along the side edge of a door glass among the upper sides of a door sash. The vicinity of the side of the upper side of the door sash is a portion located at the end of the upper edge of the door glass. By compressing the outside part of the glass run over the entire upper edge of the door glass by causing the side stopper to press the door glass against the outside part of the glass run at the upper edge of the door glass. Is possible.

  The glass stopper and the side stopper portion may be integrally made of the same sheet metal and may be independent of the door sash. By providing the glass stopper and the side stopper as independent members, it is easier to adjust the pressing action of the door glass on the outside portion of the glass run. Further, if it is made of sheet metal, it is possible to suppress the secular change and maintain its performance.

  The door glass 112 is surrounded by a door sash 114 that is a window frame, and moves up and down along the door sash 114. The door sash 114 is provided with a glass run 116 along the edge of the door glass 112. The glass run 116 is a resin or rubber-made sealing member that seals the gap between the door sash 114 and the door glass 112.

  In the door structure 100, two glass stoppers 118 are provided on the upper side of the door sash 114 (sash upper side portion 114a). FIG. 2 is an enlarged perspective view of the glass stopper 118 of FIG. The glass stopper 118 is a sheet metal member independent of the door sash 114 (see FIG. 1B), and interferes with the upper edge 122 of the door glass 112 via the glass run 116, whereby the door glass 112. Has the function of regulating the rise of The glass stopper 118 is roughly divided into a base portion 118a joined to the door sash 114, and a side stopper portion 118b formed so as to rise from the base portion 118a.

  In FIG. 2, the glass run 116 and a part of the door glass 112 are illustrated in a fragmentary manner. The glass run 116 is formed in a U-shaped cross section into which the upper edge 122 of the door glass 112 can be inserted. Briefly describing each part of the glass run 116, the vehicle interior portion 124 that contacts the vehicle inner surface 112a (the vehicle interior surface in the vehicle width direction) of the door glass 112, and the upper portion 126 that contacts the upper end surface 112b of the door glass 112. The vehicle has a vehicle exterior portion 128 that contacts the vehicle exterior surface 112c (the vehicle exterior surface in the vehicle width direction) of the door glass 112.

  As a function of the glass stopper 118 in the present embodiment, the side stopper portion 118 b pushes and bends the vehicle interior portion 124 of the glass run 116, and presses the door glass 112 against the vehicle exterior portion 128 of the glass run 116. Accordingly, in the present embodiment, the outside portion 128 of the glass run 116 is compressed to suppress its thickness, and the dimension D1 (see FIG. 3) of the outside portion 128 of the glass run 116 relative to the door glass 112 is reduced. As a result, the generation of air resistance and noise that can occur at the vehicle outer side during traveling is suppressed.

  FIG. 3 is a cross-sectional view taken along the line AA in FIG. The configuration of the glass run 116 will be described in more detail with reference to FIG. The glass run 116 is attached to the flange portions 130 a and 130 b of the door inner panel 108 and the door outer panel 110 constituting the door sash 114. The vehicle interior portion 124 of the glass run 116 includes a vertical wall portion 132 that extends vertically in the vehicle, a seal lip portion 134 that protrudes from the lower end of the vertical wall portion 132 toward the door glass 112, and the vehicle inner side from the lower end of the vertical wall portion 132. An inner lip 136 projecting into the body. The seal lip portion 134 is curved and extends upward on the door glass 112 side, and contacts the door glass 112 to prevent intrusion of rainwater or the like from the outside of the vehicle. The inner lip portion 136 extends along the flange portion 130a of the door inner panel 108 and is connected thereto.

  The vehicle outer portion 128 of the glass run 116 also extends from the lower end of the vertical wall portion 138 to the door glass 112 side, and from the lower end of the vertical wall portion 138 to the vehicle outer side. An outer lip 142 is included. The seal lip 140 is curved and extends upward on the door glass 112 side, and contacts the door glass 112 to prevent intrusion of rainwater or the like from the outside of the vehicle. The outer lip portion 142 is curved and extends upward along the flange portion 130b of the door outer panel 110, and is connected to the flange portion 130b.

  The side stopper portion 118b of the glass stopper 118 interferes with the vertical wall portion 132 in the vehicle interior portion 124 of the glass run 116, and pushes and bends the vertical wall portion 132 toward the vehicle outer portion 128 side. As a result, the door glass 112 is pressed against the seal lip 140 of the vehicle exterior portion 128, and the vehicle exterior portion 128 including the seal lip portion 140 becomes thin.

  The side stopper portion 118b can come into surface contact with the vertical wall portion 132, and is configured to push a protruding portion 144 provided in a region above the seal lip portion 134 in the vertical wall portion 132 in particular. . The protruding portion 144 is a portion protruding toward the door glass 112 on the door glass 112 side of the vertical wall portion 132. The surface on the door glass 112 side of the protruding portion 144 is provided in parallel with the side stopper portion 118b. The side stopper portion 118b can suitably exert the pressing action of the door glass 112 against the vehicle outer side portion 128 through the protruding portion 144. Further, since the side stopper portion 118b does not press the seal lip portion 134 of the vehicle interior portion 124, the side stopper portion 118b does not affect the sealing performance of the seal lip portion 134, and in addition, the door glass 112 does not hinder the lifting and lowering operation.

  FIG. 4 is a diagram illustrating an operation when the door glass 112 of FIG. 3 is closed. FIG. 4A illustrates the state of the door glass 112 immediately before closing. As illustrated in FIG. 4A, the upper edge 122 of the raised door glass 112 first comes into contact with the seal lip 134 of the glass run 116, and then comes into contact with the protrusion 144 at the back thereof.

  The side stopper portion 118b is inclined so that the door glass 112 is pushed toward the vehicle outer side 128 as it goes upward, and the surface of the protruding portion 144 is also inclined in parallel with the side stopper portion 118b. In the present embodiment, as an example, the angle α of the surface of the protrusion 114 with respect to the glass entrance direction is set to be about α = 30 °, and the groove of the glass run 116 becomes narrower toward the back. It has become. With these configurations, as illustrated in FIG. 4B, the door glass 112 in the closed state is pressed against and closely contacts the seal lip 140 of the vehicle outer side portion 128 of the glass run 116. In this way, the vehicle outer portion 128 of the glass run 116 is reduced in thickness, and the dimension D1 of the vehicle outer portion 128 is reduced.

  Here, FIG. 5 is a diagram illustrating a configuration of a conventional door structure 10. As illustrated in FIG. 5, in the conventional glass run 11, the door glass 112 in the closed state is arranged at the center of the seal lip portions 14 a and 14 b of the glass run 11. Further, the glass stopper 16 has only a function of regulating the rise of the door glass 112 through the glass run 11. Compared to this configuration, in the door structure 100 illustrated in FIG. 4B, the door glass 112 is biased toward the seal lip 140 side of the vehicle exterior portion 128. Therefore, in this embodiment, the dimension D1 of the vehicle outer side portion 128 on the vehicle outer side of the door glass 112 can be made lower than the size D2 of the vehicle outer side portion 18 in the conventional glass run 10. Thus, in this embodiment, it is possible to suppress the generation of air resistance and wind noise during traveling.

  In the present embodiment, as illustrated in FIG. 1B, the side stopper portion 118b is replaced by the side edge of the door sash 114 along the side edges 113a and 113b of the door glass 112 (the sash on the front side of the vehicle). It is provided at a total of two locations in the vicinity of the side portion 114b and the sash side portion 114c on the rear side of the vehicle. The vicinity of the sash side portions 114b and 114c is also the position of the end of the upper edge 122 of the door glass 112. Therefore, the outside portion of the glass run 116 of the door glass 112 by the side stopper portion 118b (see FIG. 2) at that position. By causing the pressing action to 128, the dimension D1 of the vehicle exterior portion 128 can be suitably suppressed over the entire upper edge 122 of the door glass 112. The number of glass stoppers 118 can be changed as appropriate.

  In the present embodiment, as illustrated in FIG. 2, the glass stopper 118 is an independent member from the door sash 114, and the side stopper portion 118 b is provided on the glass stopper 118. However, the glass stopper 118 and the side stopper 118b can be provided integrally with the door sash 114. If the glass stopper 118 is a sheet metal member independent of the door sash 114 as in this embodiment, the position of the pressing action of the door glass 112 can be arbitrarily adjusted. In addition, a resin or the like can be used as the material of the glass stopper 118, but if it is made of sheet metal, its performance can be maintained while suppressing the secular change. Further, if the glass stopper 118 and the side stopper portion 118b have a simple configuration as in the present embodiment, it is possible to prevent an increase in cost, an increase in weight, and a deterioration in fuel consumption.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used for a vehicle door structure including a door sash and a door glass that can be raised and lowered along the door sash.
