Description

  This specification discloses a structure of a side door provided on a side of a vehicle.

  2. Description of the Related Art Generally, a side door provided on a side of a vehicle is provided with a window for visually recognizing the outside and taking in outside air. Such windows were often provided in the upper half area of the side door.

  In some vehicles, it has been proposed to provide two windows on a side door for the purpose of expanding the field of view and improving the feeling of opening. For example, Patent Literature 1 proposes that a side door be provided with a relatively large door window and a side view window disposed below the door window. With this configuration, the field of view when viewing the outside from the vehicle interior can be widened.

JP 2011-184022 A

  However, in Patent Literature 1, different window panels (window glass) are fitted in the door window and the side view window, respectively, and the two windows have a poor sense of unity. As a result, the side door disclosed in Patent Literature 1 has not been described as a design having a sufficient open feeling.

  Here, in order to enhance the feeling of openness, it is more desirable to provide a single large window than to provide a plurality of completely separate windows. However, when a single large window is provided, it is difficult to secure the strength of the side door. That is, conventionally, it has been difficult to achieve both the maintenance of the strength and the improvement of the open feeling in the side door.

  Thus, the present specification discloses a side door that can provide a design with a more open feeling while ensuring the strength of the side door.

  The side door disclosed in this specification is a structure of a side door provided on a side portion of a vehicle, and is formed by joining an inner panel and an outer panel disposed outside the inner panel in the vehicle width direction. A door body configured, wherein a first window opening, a second window opening, a door body formed, a first glass portion covering the first window opening, the second window for A single glass pane integrally formed with a second glass part covering the opening, and a connecting glass part connecting the first glass part and the second glass part, and a vehicle width of the connecting glass part. A closed cross-section structure in which the inner panel and the outer panel are joined to form a closed cross-section at a position on the inner side in the direction, wherein the closed cross-section structure extends so as to cross the connecting glass portion in a plane direction; Disposed between the cross-sectional structure and the connecting glass part, An outer trim covering the structure from the outside in the vehicle width direction, characterized in that is provided.

  By covering the opening for the first window and the opening for the second window with a single window glass, the sense of unity of the opening for the first window and the opening for the second window is increased, and an impression as if there is one large window is provided. give. On the other hand, the strength of the side door can be kept high because the closed cross-section structure extending so as to cross the connecting glass portion in the plane direction is provided. Further, since the closed cross-section structure can be hidden by the outer trim, the design of the side door can be kept high.

  In this case, at a position on the inner side in the vehicle width direction of the connecting glass portion, a peripheral portion of the first window opening and a peripheral portion of the second window opening of a panel joining portion joining a peripheral edge of the inner panel and a peripheral edge of the outer panel. May be provided with a liquid-tight seal.

  With this configuration, it is possible to effectively prevent the liquid from entering the inside of the door body.

  Further, the first glass portion occupies most of the upper half of the door body, and the second glass portion moves rearward as the vehicle progresses downward in the lower half region of the door body. And the connection glass part may connect a lower end and a front end of the first glass part to an upper end and a front end of the second glass part.

  With such a configuration, most of the side doors are covered with the window glass, so that a more open design can be obtained.

  ADVANTAGE OF THE INVENTION According to the side door disclosed by this specification, a design with a more open feeling is obtained, ensuring the strength of a side door.

It is the figure which looked at the side door from the vehicle side. It is a front view of a fixed window glass. FIG. 2 is an AA end view of FIG. 1. It is a BB end view of FIG. It is an end elevation which shows an example of the conventional side door.

  Hereinafter, the structure of the side door 10 of the vehicle will be described with reference to the drawings. FIG. 1 is a diagram of the side door 10 as viewed from the side of the vehicle. FIG. 2 is a front view of the fixed window glass 14 provided on the side door 10. 3 is an AA end view of FIG. 1, and FIG. 4 is a BB end view of FIG. In the following drawings, “Fr”, “Up”, and “Out” respectively indicate the front, the upper side, and the outer side in the vehicle width direction of the vehicle. In FIG. 1, the window opening of the door main body 12 is shown in white. In addition, the portion of the door body 12 that is covered with the fixed window glass 14 is light hatched, and the portion that is not covered by the fixed window glass 14 is dark hatched.

  A side outer panel (not shown) is provided on a side portion of the vehicle, and a front opening and a rear opening for an occupant to get on and off are formed in the side outer panel in a line in front and rear. The side door 10 shown in FIG. 1 is a front side door 10 that covers a front opening. The side door 10 has a door body 12 in which a plurality of window openings 20, 22, 24 are formed, and window glasses 14, 16 covering the window openings 20, 22, 24.

  The door main body 12 is configured by joining a door outer panel 42 (see FIGS. 3 and 4) and a door inner panel 44 (see FIGS. 3 and 4) located inside the door outer panel 42 in the vehicle width direction. . The door outer panel 42 and the door inner panel 44 are both sheet metal members made of metal such as steel. The door outer panel 42 has a substantially dish-like shape bulging inward in the vehicle width direction, and the door inner panel 44 has a substantially dish-like shape bulging inward in the vehicle width direction. ing. By joining the flange 46 of the door outer panel 42 and the flange 48 of the door inner panel 44 by welding, a thick door body 12 is formed.

  The door inner panel 44 may be configured by a single panel member, or may be configured by joining a plurality of panel members in a surface direction. Similarly, the door outer panel 42 may be constituted by a single panel member, or may be constituted by joining a plurality of panel members in the surface direction. When the flanges 46 and 48 of the door outer panel 42 and the door inner panel 44 are joined to each other, a closed space is formed between the panels 42 and 44. In this closed space, a reinforcing panel (for example, inner reinforcement 49 or the like) for reinforcing the door body 12 may be provided. Further, in the closed space, an impact beam for protecting the passenger compartment from a side collision, an elevating mechanism (both not shown) for elevating and lowering an elevating window glass 16, which will be described later, may be arranged.

  An inside trim 52 is provided inside the door main body 12 in the vehicle width direction. The inner trim 52 is a panel material constituting a design surface of the side door 10, and is made of resin or the like. A door pocket, a door inner handle, and the like are formed in the inner trim 52. The inner trim 52 may also be constituted by a single panel member, or may be constituted by combining a plurality of panel members.

  An upper window opening 20, a lower window opening 22, and an elevating window opening 24 are formed in the door main body 12 (therefore, the door outer panel 42 and the door inner panel 44). The upper window opening 20 is a relatively large opening that occupies most of the upper half of the side door 10. The lower window opening 22 is provided below the upper window opening 20 and has a substantially rectangular shape that is inclined so as to move downward from the front of the vehicle toward the rear. The front edge of the lower window opening 22 is located on an extension of the front edge of the upper window opening 20, and the front edge of the upper window opening 20 and the front edge of the lower window opening 22 are different from each other. Are given in a row, and the sense of unity between the upper window opening 20 and the lower window opening 22 is enhanced. Hereinafter, a region of the door body 12 between the lower end of the upper window opening 20 and the upper end of the lower window opening 22 is referred to as a “connection portion 40”.

  The lifting window opening 24 is provided above and behind the door body 12. An elevating window glass 16 is fitted into the elevating window opening 24 so as to be able to move up and down. The user can take in outside air into the vehicle cabin through the elevating window opening 24 by lowering the elevating window glass 16 as necessary.

  The upper window opening 20 and the lower window opening 22 are covered with a single fixed window glass 14. The fixed window glass 14 is a fixed glass that is attached to and fixed to the door body 12 from the outside. In this example, as shown in FIG. 2, the fixed window glass 14 includes an upper glass part 30 that covers the upper window opening 20, a lower glass part 32 that covers the lower window opening 22, and an upper glass part 30. It can be roughly divided into a connection glass part 34 connecting the upper glass part 30. The connection glass part 34 connects the front end of the lower end of the upper glass part 30 and the front end of the upper end of the lower glass part 32, and the fixed window glass 14 has a substantially C shape as a whole.

  Here, the reason why the upper window opening 20 and the lower window opening 22 are covered with a single fixed window glass 14 will be briefly described. The larger the window provided in the side door 10, the wider the field of view becomes, and the feeling of opening is improved. However, when an excessively large opening is provided in the side door 10, it is difficult to maintain the strength of the side door 10. Therefore, in this example, two window openings, an upper window opening 20 and a lower window opening 22, are provided, and a part of the door body 12 (the connecting portion 40) is present between the two window openings 20,22. In this way, the strength of the side door 10 is secured.

  However, when the upper window and the lower window are simply completely separated, the open feeling of the side door 10 is not sufficiently improved, and the comfort of the passenger compartment is reduced. Therefore, in this example, the upper window opening 20 and the lower window opening 22 are covered with a single fixed window glass 14. With such a configuration, the sense of unity between the upper window and the lower window is increased, and as if there is one large window (a window in which the upper window opening 20 and the lower window opening 22 are connected). You can give an impression like. By giving such an impression that there is such a large window, the open feeling of the side door 10 can be remarkably improved.

  Also, by covering the two window openings 20 and 22 with a single fixed window glass 14, the edges of the window glass are held at the lower end of the upper window opening 20 and the upper end of the lower window opening 22. There is no need to provide a holding structure. As a result, each window opening can be enlarged by the size of the holding structure.

  However, when the upper window opening 20 and the lower window opening 22 are covered with a single fixed window glass 14, there is a problem that the connection portion 40 of the door body 12 has a poor appearance. This will be described with reference to FIG. FIG. 3 is an AA end view of FIG. As described above, the flanges 46 and 48 are formed on the peripheral edges of the door inner panel 44 and the door outer panel 42, respectively, and the door main body 12 is configured by joining the flanges 46 and 48 to each other. Therefore, the panel joining portion 62 in which the flanges 46 and 48 are overlapped and joined exists on the periphery of the upper window opening 20 and the periphery of the lower window opening 22.

  In the AA line, the periphery of the fixed window glass 14 is attached to the door main body 12 so as to overlap the panel joining portion 62 in the thickness direction. At this time, if the panel joining portion 62 is seen from the outside, the appearance is poor, and therefore, a mask portion 58 provided with opaque coating, for example, a black ceramic coating, is provided on the periphery of the fixed window glass 14. As a result, the panel joint portion 62 cannot be visually recognized from the outside of the vehicle, so that it is possible to prevent a decrease in beauty. Further, since the inside trim 52 is provided inside the door main body 12, the panel joint portion 62 is not seen from the vehicle interior, so that it is possible to prevent a decrease in aesthetics.

  By the way, when such a mask portion 58 is provided in order to hide the panel joint portion 62 in the connecting portion 40, the fixed window glass 14 gives an impression of being divided into upper and lower portions, and a sense of unity and openness are impaired. . Therefore, the panel joint portion 62 in the connection portion 40 cannot be hidden by the mask portion 58. Therefore, in this example, in the connecting portion 40, the outer trim 50 is disposed between the door outer panel 42 and the fixed window glass 14, and the connecting portion 40 is hidden by the outer trim 50.

  This will be described with reference to FIG. As shown in FIG. 4, in the connection portion 40, the door outer panel 42 and the door inner panel 44 are joined to each other to form a closed-section structure 13 having a closed section. The closed-section structure 13 extends so as to cross the connecting glass portion 34 in the vehicle front-rear direction (plane direction) inside the connecting glass portion 34 in the vehicle width direction.

  At the upper and lower ends of the closed cross-section structure 13, there are panel joints 62 that join the flanges 46 and 48 of the door outer panel 42 and the door inner panel 44. The panel joint 62 has a poor appearance as it is. Therefore, in this example, as shown in FIG. 3, an outer trim 50 that covers and hides the closed cross-sectional structure 13 from the outside is provided between the connecting glass part 34 and the closed cross-sectional structure 13. The outer trim 50 is a design panel made of resin or the like. The outer trim 50 has a substantially C-shaped cross section that is opened inward in the vehicle width direction, and covers and hides not only the outside of the closed cross-section structure 13 in the vehicle width direction but also the upper and lower parts. A fastening portion 54 is formed on the rear surface of the outer trim 50 (a surface that cannot be seen from the outside of the vehicle). The fastening portion 54 and the door outer panel 42 are connected by a fastening member 56 such as a clip.

  Further, an inner trim 52 is provided on the inner side in the vehicle width direction than the closed-section structure 13. By providing such an inner trim 52, the fastening portion 54 is hidden from the inside of the vehicle.

  As described above, in the present example, the closed section structure 13 which is a part of the door body 12 is traversed by the connecting portion 40 between the upper window and the lower window. Thereby, the strength of the side door 10 can be kept high. Further, in this example, by disposing the outer trim 50 between the fixed window glass 14 and the closed-section structure 13, it is not necessary to provide the fixed window glass 14 with the mask portion 58 that crosses the connecting portion 40. The panel joint 62 of the closed-section structure 13 can be hidden. Thus, it is possible to maintain a high sense of unity between the upper window and the lower window, and prevent a reduction in aesthetics due to the visible panel joint 62. As a result, according to this example, it is possible to improve the open feeling and design of the side door 10 while maintaining the strength of the side door 10.

  By the way, in this example, as shown in FIG. 3, between the door outer panel 42 and the door inner panel 44, an inner reinforcement (hereinafter referred to as "inner R / F") is used to keep the strength of the side door 10 higher. 49). The inner R / F 49 is a panel material made of metal such as steel, and is provided to reinforce the door body 12. The inner R / F 49 extends from near the front end of the door body 12 to near the rear end via the connecting portion 40, as shown in FIG. By providing such an inner R / F 49, the strength of the connecting portion 40 and thus the strength of the side door 10 can be further improved.

  In this example, the liquid-tight seal 60 is applied to the upper and lower ends of the closed-section structure 13, that is, the panel joint 62. The liquid-tight seal 60 is configured by, for example, applying a curable resin so as to cover the ends of the panels 42 and 44 and the inner R / F 49. The reason for providing such a liquid-tight seal 60 will be described in comparison with the prior art. In the conventional side door 10, the window glass 70 is often held between the door inner panel 44 and the door outer panel 42 as shown in FIG. For this reason, a sealing member such as a glass run 64 is disposed on the periphery of the door inner panel 44 and the periphery of the door outer panel 42 that constitute the periphery of the window opening. In such a configuration, the liquid tightness of the door main body 12 is ensured without separately providing the liquid tight seal 60.

  On the other hand, in this example, as described above, the fixed window glass 14 is attached to the outside of the door main body 12, that is, to the outside of the door inner panel 44 and the door outer panel 42. In this case, since a sealing member such as a glass run 64 is not attached to the panel joint 62 between the door inner panel 44 and the door outer panel 42, liquid tightness at the panel joint 62 is not ensured. Therefore, in this example, the liquid-tight seal 60 is provided at the panel joint 62 that forms the periphery of the upper window opening 20 and the lower window opening 22. With this configuration, it is possible to prevent liquid from entering the door body 12 (the closed-section structure 13).

  The configuration described so far is merely an example. While two or more window openings are covered with a single fixed window glass 14, the two window openings are located inside the fixed window glass 14 in the vehicle width direction. If the closed cross-section structure 13 and the outer trim 50 that covers the closed cross-section structure 13 are arranged in the connecting portion 40, other configurations may be appropriately changed. Therefore, the fixed window glass 14 may be configured to cover not two vertically arranged window openings but two vertically arranged window openings. Further, in this example, the inner R / F 49 is provided between the door inner panel 44 and the outer panel in order to reinforce the side door 10, but such a reinforcing panel may be omitted, or a larger number may be provided. You may.
