Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle door structure formed with an intermediate window portion below a window portion.
[0002]
[Prior art]
In automobiles (vehicles), visibility on the side of the vehicle body is required to improve safety.
[0003]
Therefore, a technique for increasing the window area of the automobile door has been proposed. In this technology, among the upper ends of the door panel part with the built-in lifting window, the front side of the upper end part outside the vehicle sandwiching the lifting window is made a large step so as to be lower than other parts, and this step forms a wall shape outside. There is a technique in which an opening is formed in the exposed panel portion on the vehicle interior side so that the side of the door can be visually recognized from the inside of the vehicle through the opening (see, for example, Patent Document 1).

[Problems to be solved by the invention]
By the way, normally, when the raising / lowering window of the vehicle door is at the lowest lowered position, the upper edge of the raising / lowering window is covered with the upper end of the door panel.
[0006]
However, in the structure in which the window area is enlarged by using the step structure as described above, the outside part of the passenger compartment at the upper end portion of the door panel is stepped. The upper edge of is exposed outside the vehicle as it is. That is, the upper edge of the lifting window is exposed to the outside.
[0007]
For this reason, when the window is stored, an object is likely to come into contact with the upper edge of the lifting window from the outside. In particular, since most of the elevating window is made of a glass member, the upper edge of the elevating window may be damaged by an applied impact or load.
[0008]
In addition, the structure of the door panel that has a stepped outer part at the upper end of the door panel is required to suppress the exposure of the upper edge of the lifting window. It is necessary to reduce the area of the opening under the window to improve the visibility, and it is difficult to achieve both visibility.
[0009]
SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle door structure that can achieve both prevention of breakage of an elevating window and securing sufficient visibility of a side of a door.
[0010]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on an embodiment shown in FIGS.
[0015]
In FIG. 1, reference numeral 1 denotes a vehicle body of a car (vehicle), 2 denotes a front door that can be opened and closed at a side portion of the vehicle body 1, and 3 denotes a rear door. Each of the doors 2 and 3 has a structure with a large window area. Since the same structure is employed for the front door 2 and the rear door 3, the door on one side, for example, the front door 2 will be described here.
[0016]
Here, the front door 2 uses, for example, a door main body 5 that is entirely constituted by a panel structure. As shown in FIG. 4, for example, the door main body 5 includes a rectangular main panel outer panel portion 7 in which a U-shaped window frame outer panel portion 6 projects from the upper end portion, and a window run channel 8 (see FIG. 2 from the upper end portion). 3), and the inner panel portion 10 for the main body from which the inner panel portion 9 for the window frame is attached is formed. More specifically, the plate surface of the inner panel portion 10 for the main body is formed with, for example, a rectangular bulging portion 11 that protrudes toward the vehicle interior side, and is joined to the outer panel portion 7 for the main body to form a flat box-shaped door panel portion. 13 has a door body 5 having a lower portion and a window frame portion 14 having a built-in run channel 8 on the upper portion. A window portion 15 is formed by the window frame portion 14. A weather strip 4 is incorporated in each part of the run channel 8. A slit-shaped window elevator 12 is formed at the upper end of the door panel 13.
[0017]
Moreover, the upper end part of the door panel part 13 which forms the lower end of the window part 15 is notched to the lower side. This notched portion is an arm portion 16 protruding from the front portion of the door panel portion 13 as shown in FIGS. 1 and 2, for example, at the upper end portion of the main body outer panel portion 7 and the upper end portion of the main body inner panel portion 10. It is formed with a recess 18 that is gradually cut out from the vicinity where there is a gap, and then cut out from the vehicle rear portion of the door panel portion 3 to the arm portion 17 while maintaining a certain depth. The lower side of the window portion 15 is expanded by a recess 18 that occupies most of the door panel portion 13 in the front-rear direction. An intermediate window 19 is formed at the upper end of the door panel 13 by the recess 18. A belt line molding 22 with a weather strip 21 is assembled to the portion of the upper end portion of the outer panel 7 for the main body that forms the opening edge of the window lift 12 as shown in FIGS. Similarly, a weather strip 23 is attached to the upper end of the inner panel 9 for the main body.
[0018]
In addition, an elevating window panel 25 made of glass, for example, is housed inside the door panel portion 13 as an elevating window. The elevating window panel 25 has an upper end portion indicated by a two-dot chain line α in FIG. 1 and a window portion 15 by an elevating mechanism 26 (only part of which is shown in FIG. 4) assembled in the door panel portion 13 together with the window 25. The lower end position located between the intermediate window portion 19 and the upper end portion indicated by the solid line β in FIG. 1 moves up and down between the uppermost position where the window portion 15 is fully closed.
[0019]
Further, between the arm portions 16 and 17 arranged in the front-rear direction of the window frame portion 14, a space between the window portion 15 and the intermediate window portion 19 is, for example, a belt line of the door panel portion 13, specifically, the original intermediate window portion 19. An elongated partition portion 30 is provided to partition vertically according to the upper end portion of the door panel portion 13 that is not provided. As shown in FIGS. 2 and 3, the partition portion 30 straddles the vehicle exterior side of the arm portions 16 and 17 sandwiching the hoistway 24 of the elevating wind panel 25, for example, between the panel surfaces on the outer side of the arm portions 16 and 17. A garnish, for example, a beltline garnish 31, and an elongated interior portion 32 straddling the inner side of the arm portions 16, 17, for example, the inner side panel surfaces of the arm portions 16, 17 are combined. More specifically, the belt line garnish 31 has a space between the arm portions 16 and 17 (in the front-rear direction) following the upper end of the lift window panel 25 when it is at the lowest lowered position as shown in FIGS. ) And a weather strip 34 attached to the upper end of the back surface of the decorative portion 33 is used. Note that a decorative surface (design surface) 35 formed on the outer surface of the decorative portion 33 faces the outside of the passenger compartment. The interior portion 32 has, for example, a cross section extending between the arm portions 16 and 17 (in the front-rear direction) following the upper end portion of the elevating wind panel 25 when in the lowest lowered position as shown in FIGS. A substantially U-shaped elongated reinforcement member 37, a weather strip 38 attached to the upper end of the rear wall of the reinforcement member 27, and a trim that covers the surface side (the vehicle interior side) of the reinforcement member 37 A structure combining the portion 39 is used. The belt line garnish 31 and the interior portion 32 (reinforcement member 37, trim portion 39) are arranged in parallel so that the weather strip 34 and the weather strip 38 face each other across the hoistway 24. In addition, the decorative portion 33, the reinforcement member 37, and the trim portion 38 all have a width dimension that covers the upper edge portion of the elevating wind panel 25 at the lowest position. Note that substantially L-shaped seats 41 that overlap with the front and rear panel portions of the arm portions 16 and 17 are formed at both ends of the reinforcement member 37. As shown in FIG. 2, the belt line garnish 31 and the reinforcement member 37 include a fastener, such as a bolt 40, from both ends of the reinforcement member 37, and the arm portions 16 and 17 that avoid the run channel 8. By passing through the parts of the outer panel part 6 and the inner panel part 9 and screwing into the boss part 42 formed on the back surface of the decorative part 33, the arm parts 16 and 17 can be detached from the indoor and outdoor side parts, respectively. It is concluded. The fixed beltline garnish 31 leaves the intermediate window 19 and covers only the upper edge of the lift window panel 25 at the lowest position from the outside of the vehicle. Further, for example, as shown in FIGS. 3 and 4, the trim portion 39 is integrally formed on an upper portion of a door trim 44 that is detachably attached to the entire surface of the door panel portion 13 on the vehicle interior side. Then, by cooperation of the trim portion 39 supported by the door trim 44 and the reinforcement member 37 supported by the arm portions 16, 17, the upper edge of the elevating wind panel 25 at the lowest position is left, leaving the intermediate window portion 19. Only the part is covered from the inside of the car. That is, when the elevating window 25 is in the lowest lowered position, the upper edge portion of the elevating window 25 is protected from the inside of the vehicle and the outside by the partition portion 30.
[0020]
Further, when the door trim 44 and the bolt 40 are removed, the beltline garnish 31 can be removed from the window frame portion 14. Note that a portion of the door trim 44 that faces the intermediate window portion 19 is opened so that the intermediate window portion 19 can be seen through. 45 shows the open part. In the figure, reference numeral 46 denotes a door outer handle provided on the outer surface of the door panel portion 13.
[0021]
The rear door 3 has the same structure of the intermediate window portion 19 and the partition portion 30 as the front door 2. In addition, about the rear door 3, the same code | symbol which added "a" to the end is attached to the same part as the part demonstrated with the front door 2 in drawing, and the description was abbreviate | omitted.
[0022]
By adopting the structure in which the window area is increased by using the concave portion 18 and the partition portion 30 in this way, as shown in FIGS. 1 and 2, the elevating window panel 25 is moved up and down at the time of storing the window (the lowest lowered position). The upper edge of the wind panel 25 is covered and hidden from both inside and outside the vehicle by a beltline garnish 31, a reinforcement member 37, and a trim part 39 that partition the window 15 and the intermediate window 19, so that objects and passengers can hit it. Therefore, it is possible to prevent the upper edge of the lift window panel 25 from being damaged by an external impact or load. In addition, the intermediate window portion 19 can independently determine the window area independently by adopting a structure that prevents the upper edge of the elevating wind panel 25 from being damaged by the beltline garnish 31 or the trim portion 39. The window area of the window portion 19 can be increased.
[0023]
Therefore, it is possible to achieve both the prevention of breakage of the elevating wind panel 25 and the securing of sufficient visibility on the side of the door.
[0024]
Moreover, since only the partition part 30 is employed, the structure is simple. In particular, since the partition portion 30 is simply provided with the garnish such as the beltline garnish 31 and the interior portion such as the reinforcement member 37 and the trim portion 39 on the window frame portion 14, the partition portion 30 has a simple structure and has a good appearance. In addition, since the reinforcement member 37 is employed, the interior portion 30 is secured with high rigidity.
[0025]
In addition, since the beltline garnish 31 has a structure that is detachably attached to the window frame portion 14, even if the garnish 31 is damaged, the beltline garnish 31 is removed from the window frame portion 14. Simply remove it and replace it with a new beltline garnish 31.
[0026]
The present invention is not limited to the above-described embodiments, and it goes without saying that various modifications may be made without departing from the spirit of the present invention. For example, in one embodiment, the structure in which the partition portion is provided along the belt line of the door has been described as an example. However, the present invention is not limited to this. For example, the partition portion is provided not only on the belt line but also on a point above the belt line. May be.
[0027]
【The invention's effect】
As described above, according to the first aspect of the present invention, the upper edge of the lift window in the lowest position is protected by the partition portion both inside and outside the vehicle. The part does not need to come into contact with external objects. In addition, the partition portion allows the intermediate window portion to independently expand the window area without being affected by the lifting window.
[0028]
Therefore, with a simple structure, it is possible to achieve both prevention of breakage of the lifting window and securing sufficient visibility of the side of the door by the intermediate window portion.
[0029]
According to the second aspect of the invention, in addition to the above-described effects, the partition portion only needs to be a combination of a garnish and an interior portion. Therefore, the partition portion has a simple structure and is excellent in appearance.
[0030]
According to the invention described in claim 3, in addition to the above-described effect, there is an effect that even if the garnish is broken, it can be dealt with by replacing the garnish.
