Japanese Patent Laid-Open No. 11-129761 JP 2005-41483 A

By the way, the vehicle body is required to have a substantially barrel shape so that the shape when viewed from above in the vertical direction (hereinafter simply referred to as the vertical direction) along the direction of gravity is most bulged at the approximate center in the traveling direction. It is done. However, if the vehicle body is formed in a simple barrel shape, the vehicle width at the rear portion in the traveling direction (hereinafter simply referred to as the rear portion) becomes too small if the vehicle body has a long longitudinal length.

For this reason, in order to expand the vehicle width at the rear part of the vehicle body, the door is formed to bulge outward in the vehicle width direction, and the belt line part of the door panel is moved in the vertical direction in order to improve the view from the vehicle interior. It is conceivable to form a bend. However, when the door is formed to bulge outward in the vehicle width direction and the belt line portion of the door panel is bent in the vertical direction, it is necessary to provide a plurality of bent portions on the door panel. There is a problem that becomes complicated.

Therefore, the present invention has been made in view of the above-described circumstances, and without complicating the structure, the shape of the vehicle body when viewed from above in the vertical direction can be formed into a barrel shape, and the view from the vehicle interior can be reduced. A door structure that can be improved is provided.

The first arm portion 64 is a plate-like member extending so as to incline backward as it goes upward, and an upper end portion 64 a is slidably connected to the glass holder 61. On the other hand, the lower end portion 64 b of the first arm portion 64 is connected to the window motor 63 and is rotatable about an output shaft (not shown) of the window motor 63.

The second arm portion 65 is a plate-like member extending to incline forward as it goes upward. The second arm portion 65 and the first arm portion 64 intersect each other at the approximate center in the longitudinal direction. And the 1st arm part 64 and the 2nd arm part 65 are rotatably connected via the rotation support part 67 in the position which cross | intersects.
Further, the upper end portion 65 a of the second arm portion 65 is rotatably connected to the front end portion 61 a of the glass holder 61. On the other hand, the lower end portion 65 b of the second arm portion 65 is slidably connected to the guide rail 66. The guide rail 66 is provided so as to extend in the front-rear direction.

Here, the position of the window motor 63 is the position of the boundary A1 between the beltline front portion 15a and the beltline rear portion 15b in the beltline portion 15 of the door outer panel 8, that is, the first inclination angle change point P1 and the second inclination angle. It is set to a position that does not overlap in the vertical direction with respect to the position of the change point P2. That is, the position of the window motor 63 and the position of the rotation support portion 67 are set in front of the position of the boundary A1 between the beltline front portion 15a and the beltline rear portion 15b.

On the other hand, the position of the rotation support portion 67 of the regulator unit 62 is the position of the boundary A1 between the beltline front portion 15a and the beltline rear portion 15b in the beltline portion 15 of the door outer panel 8 (first inclination angle change point P1 and 2) (position of 2 tilt angle change point P2) and a position that does not overlap in the vertical direction. That is, the position of the rotation support part 67 is set behind the position of the boundary A1 between the beltline front part 15a and the beltline rear part 15b.
In other words, the position of the window motor 63 and the position of the rotation support portion 67 of the regulator unit 62 are in the vertical direction with respect to the position of the drain hole 39 (the lowest point P3) formed in the outer side weather strip 25. The overlapping position is not set, and is offset in the horizontal direction from the position of the drain hole 39.

Under such a configuration, when the window motor 63 is driven so as to lower the door glass 13, the first arm portion 64 rotates downward about the lower end portion 64b, and the upper end portion 64a is moved rearward. Slide towards you. Then, the second arm portion 65 rotates upward about the upper end portion 65 a and rotates about the rotation support portion 67. And the lower end part 65b of the 2nd arm part 65 slides toward back. As a result, the door glass 13 is lowered together with the glass holder 61.

On the other hand, when the window motor 63 is driven so as to raise the door glass 13, the first arm portion 64 rotates upward about the lower end portion 64b, and the upper end portion 64a slides forward. Then, the second arm portion 65 rotates downward about the upper end portion 65 a and rotates about the rotation support portion 67. And the lower end part 65b of the 2nd arm part 65 slides toward the front. Thereby, the door glass 13 rises with the glass holder 61.

(Front side door)
Next, the front side door 3 will be described with reference to FIG.
FIG. 10 is a perspective view of the front side door 3 and the rear side door 4 as seen from the outside in the vehicle width direction.
As shown in FIGS. 2 and 10, the configuration of the front side door 3 is basically the same as the configuration of the rear side door 4. That is, the front side door 3 includes a door main body 80 having a door outer panel 78 and a door inner panel 79 overlapped along the vehicle width direction, and a door lining 81 attached to the door main body 80 from the inner side in the vehicle width direction. A window frame portion 82 which is provided at the upper end of the door body 10 and defines a window opening 82a; a door glass 83 which can be moved up and down with respect to the door body 80 and opens and closes the window opening 82a; and a door inner panel 79. And an elevator device 14 for raising and lowering the door glass 83.

Here, the belt line portion 85 of the door main body 80 (door outer panel 78, door inner panel 79) in the front side door 3 has an upper inclined portion 85a that is inclined upward as it goes from the front to the rear. The upward inclined portion 85a is formed so as to be substantially parallel to the belt line rear portion 15b of the belt line portion 15 of the rear side door 4 in a plan view in the vehicle width direction.

Also, the door outer panel 78 of the front side door 3 is formed with a convex portion 87 projecting outward in the vehicle width direction below the belt line portion 85. The convex portion 87 is formed in a substantially L-shaped cross section so that the inner side in the vehicle width direction opens. And the convex-shaped part 87 is formed in the substantially linear form so that it may incline upward as the ridgeline part 87a goes back from the front. The convex portion 87 is formed so as to be continuous with the convex portion 17 formed on the rear side door 4.

(Weather strip action)
Next, the operation of the outer side weather strip 25 and the inner side weather strip 51 will be described.
First, the operation of the outer side weather strip 25 will be described with reference to FIGS. 4, 5, and 9.
As shown in FIGS. 4 and 5, the outer side weather strip 25 is formed with two

lip seal portions

34, 38, an upper lip seal portion 34 and a lower lip seal portion 38. Here, the upper lip seal portion 34 is formed so as to extend along the extended line of the upper wall portion 29 from the corner portion 33 located at the boundary between the upper wall portion 29 and the inner wall portion 28. The lip seal portion 34 is smoothly connected.

For this reason, for example, when it rains, rainwater or the like flowing down the upper lip seal portion 34 through the door glass 13 is prevented from being accumulated on the upper lip seal portion 34. In addition, since the upper lip seal portion 34 and the upper wall portion 29 are formed so as to incline upward as they approach the proximity direction, rainwater or the like on the upper lip seal portion 34 promptly enters the door outer panel 8. Discharged.

Even if rainwater or the like enters between the door glass 13 and the upper lip seal portion 34, the rainwater or the like is received by the lower lip seal portion 38. For this reason, it can suppress that rainwater etc. penetrate | invade into the inside of the door main body 10 from between the door glass 13 and the outer side weather strip 25, and the door glass 13 can be wiped off reliably.

Here, the outer side weather strip 25 is substantially V-shaped so as to protrude downward in a side view in the vehicle width direction so as to correspond to the shape of the belt line portion 15 of the door body 10. For this reason, the outer side weather strip 25 has a boundary A1 between the beltline front portion 15a and the beltline rear portion 15b, that is, a change point of the inclination angle of the beltline portion 15 (the first inclination angle change point P1 of the beltline portion 15). The second inclination angle change point P2 (see FIG. 3) is the lowest point P3.
In other words, the outer weather strip 25 (lower lip seal portion 38) is formed with a water gradient so that rainwater or the like flows to the lowest point P3. For this reason, rainwater or the like that has flowed down to the lower lip seal portion 38 accumulates at the lowest point P3.

Since the drainage hole 39 is formed at the lowest point P3 in the lower lip seal portion 38, the rain water and the like flowing down to the lower lip seal portion 38 is efficiently discharged through the drainage hole 39. The As shown in FIG. 9, rainwater or the like flowing down from the drain hole 39 of the outer side weather strip 25 hangs down on the glass holder 61 of the lifting device 14 and further hangs down.

Here, the position of the window motor 63 of the elevating device 14 and the position of the rotation support portion 67 of the regulator unit 62 are positioned so as to overlap with the position of the drain hole 39 formed in the outer side weather strip 25 in the vertical direction. It is not set and is offset in the horizontal direction from the position of the drain hole 39. For this reason, it is possible to prevent rainwater or the like flowing down from the drain hole 39 of the outer side weather strip 25 from dripping onto the wind motor 63 or the rotation support portion 67 of the regulator unit 62.

Next, based on FIG. 6, FIG. 7, the effect | action of the inner side weather strip 51 is demonstrated.
As shown in FIGS. 6 and 7, the inner side weather strip 51 has a front engagement piece 55 and a rear engagement piece for attaching the inner side weather strip 51 to the weather strip attachment portion 44 of the door lining 11. 56 is formed. The front engagement piece 55 is formed so that the tip thereof is raised rearward, and is engaged with the rear inner edge of the front engagement hole 45 of the weather strip attachment portion 44. On the other hand, the rear engagement piece 56 is formed so that the front end is cut and raised forward, and is engaged with the front inner edge of the rear engagement hole 46 of the weather strip attachment portion 44.

Here, the width W1 in the front-rear direction of each

engagement hole

45, 46 is formed larger than the width W2 in the front-rear direction of each

engagement piece

55, 56, and the vertical direction of each

engagement hole

45, 46. The width W3 is formed larger than the vertical width W4 of the

engagement pieces

55, 56. For this reason, even when the manufacturing error of the weather strip mounting portion 44 and the manufacturing error of the inner side weather strip 51 are large, the engagement holes 45 and 46 and the

engagement pieces

55 and 56 can be reliably engaged. .

The inner side weather strip 51 attached to the weather strip attachment portion 44 may be placed at a high temperature and the core material 52a may be thermally stretched. In such a case, the front engaging piece 55 is slightly displaced forward, and the rear engaging piece 56 is slightly displaced backward.

Here, a gap S 1 is formed between the front engaging hole 45 and the front engaging piece 55 on the front side of the front engaging piece 55. For this reason, it is possible to prevent the front engaging piece 55 from being pressed against the front inner edge of the front engaging hole 45 and applying an excessive force to the front engaging hole 45 and the front engaging piece 55. . On the other hand, a gap S 2 is formed between the rear engagement hole 46 and the rear engagement piece 56 on the rear side of the rear engagement piece 56. For this reason, it is possible to prevent the rear engaging piece 56 from being pressed against the rear inner edge of the rear engaging hole 46 and applying an excessive force to the rear engaging hole 46 and the rear engaging piece 56.

(effect)
In the above-described embodiment, the belt line portion 15 of the door outer panel 8 constituting the rear side door 4 is constituted by the belt line front portion 15a and the belt line rear portion 15b. And the beltline front part 15a is formed so that it may incline below while it inclines in the vehicle width direction outside as it goes to the back from the front. On the other hand, the belt line rear portion 15b is formed so as to incline in the vehicle width direction and incline upward as it goes from the front to the rear. Furthermore, at the boundary A1 between the beltline front part 15a and the beltline rear part 15b, the position of the first inclination angle change point P1 where the inclination angle in the vehicle width direction changes and the second inclination angle where the inclination angle in the vertical direction changes. The position of the change point P2 is matched. Further, the belt line portion 18 of the door inner panel 9 is configured similarly to the belt line portion 15 of the door outer panel 8. With this configuration, when the vehicle body 1 is viewed from above, the vehicle body 1 has a generally barrel shape (see FIG. 1).

Therefore, the bent portions of the

belt line portions

15 and 18 can be minimized, the structure can be simplified and the appearance of the vehicle body 1 can be enhanced. Further, since the

belt line portions

15 and 18 are V-shaped so as to protrude downward in a side view in the vehicle width direction, the field of view of the central portion in the front-rear direction of the rear side door 4 can be improved. Furthermore, since the beltline front portion 15a is inclined outward in the vehicle width direction, the vehicle width is increased, and the space in the vehicle compartment can be increased. Further, since the beltline rear portion 15b is inclined inward in the vehicle width direction, it is possible to absorb the vehicle width swelled at the beltline front portion 15a and to prevent the vehicle width from being unnecessarily widened.

Further, since the first inclination angle change point P1 and the second inclination angle change point P2 are provided in the

belt line portions

15 and 18 of the rear side door 4 located at the rear of the vehicle body 1, the vehicle width on the rear side of the vehicle body 1 Can be increased. For this reason, even if the longitudinal length of the vehicle body 1 is long, it is possible to prevent the vehicle width of the rear portion of the vehicle body 1 from becoming too narrow.

Further, the belt line portion 85 of the front side door 3 has an upper inclined portion 85a that is inclined upward as it goes from the front to the rear. The upper inclined portion 85a is formed to be substantially parallel to the belt line rear portion 15b of the belt line portion 15 of the rear side door 4 in the vehicle width direction plan view and the vertical direction plan view.
For this reason, the external appearance property of the vehicle body 1 in the vehicle width direction side view can be improved. Further, by changing the shape of the belt line portion 85 of the front side door 3 and the shape of the

belt line portions

15 and 18 of the rear side door 4, the visibility of the front side door 3 and the rear side door 4 is deteriorated. Can be prevented.

Further, the convex portion 17 is formed on the door outer panel 8 of the rear side door 4, the convex portion 87 is formed on the door outer panel 78 of the front side door 3, and the

convex portions

17 and 87 are linearly formed. It is formed to be connected. For this reason, the external appearance of the vehicle body 1 can be enhanced by the

convex portions

17 and 87. Further, the sense of unity between the front side door 3 and the rear side door 4 can be enhanced, and the appearance of the vehicle body 1 can be further enhanced. Furthermore, the rigidity of each

door

3 and 4 can be improved.

Further, the convex portion 17 of the rear side door 4 is formed in a substantially straight shape so that the ridge line portion 17a gradually approaches the belt line rear portion 15b as it goes from the front to the rear. The uncomfortable feeling that the inclination changes with the belt line rear portion 15b can be reduced.

Further, in the weather strip attachment portion 44 and the inner side weather strip 51, a gap S1 is formed between the front engagement hole 45 and the front engagement piece 55, and the rear engagement hole 46 and the rear engagement portion are formed. A gap S 2 is formed between the joint piece 56. For this reason, the thermal expansion deformation of the inner side weather strip 51 can be absorbed by the gaps S1 and S2. In other words, each of the gaps S1 and S2 can be used as a deformation allowance for absorbing the heat extension deformation of the inner side weather strip 51.

Further, the vertical width W3 of each

engagement hole

45, 46 is formed larger than the vertical width W4 of each

engagement piece

55, 56. For this reason, even if the weather strip mounting portion 44 and the inner side weather strip 51 are formed in a substantially V shape in plan view in the vehicle width direction, the manufacturing error of the weather strip mounting portion 44 and the manufacturing error of the inner side weather strip 51 are reduced. It can be absorbed by the respective engagement holes 45 and 46.

Further, the weather strip mounting portion 44 has a front engagement hole in the vicinity of a boundary A2 between the upper edge front portion 43a and the upper edge rear portion 43b of the door lining 11 formed along the

belt line portions

15 and 18. 45 and a rear engagement hole 46 are formed. By engaging the

engagement pieces

55 and 56 of the inner side weather strip 51 at this position, the mounting state of the inner side weather strip 51 can be stabilized, and the engagement holes 45 and 46 and the

engagement pieces

55 and 56 can be stabilized. The total number of 56 can be reduced.

And the belt line part 15 of the door outer panel 8 which comprises the rear side door 4 is formed in the substantially V shape so that it may protrude below in the vehicle width direction side view, and the belt line part 15 (outer side flange part) The outer side weather strip 25 attached to 16) is also substantially V-shaped so as to protrude downward in a side view in the vehicle width direction. Therefore, a water gradient is formed in the outer side weather strip 25 (lower lip seal portion 38), and even if rainwater or the like enters between the door glass 13 and the upper lip seal portion 34, Rainwater or the like accumulates at the lowest point P3 of the lower lip seal portion 38. Since the drainage hole 39 is formed at the lowest point P3 in the lower lip seal portion 38, the rain water or the like that has flowed down to the lower lip seal portion 38 is efficiently discharged through the drainage hole 39. be able to.

Further, since there is only one drainage hole 39 formed at the lowest point P3 of the lower lip seal portion 38, it is possible to suppress an increase in noise caused by the drainage hole 39 and infiltration of dust and the like into the rear side door 4. On the other hand, the structure of the outer side weather strip 25 can be simplified to suppress a decrease in rigidity.

Further, since the upper lip seal portion 34 is formed above the lower lip seal portion 38 in the outer side weather strip 25, the wiping performance of the door glass 13 by the outer side weather strip 25 can be enhanced. Here, since the upper lip seal portion 34 is located above the lower lip seal portion 38 in which the drain hole 39 is formed, rainwater or the like does not accumulate in the upper lip seal portion 34.
Further, the upper lip seal portion 34 is formed so as to extend along the extended line of the upper wall portion 29 from the corner portion 33 located at the boundary between the upper wall portion 29 and the inner wall portion 28. The seal part 34 is smoothly connected. Moreover, the upper lip seal portion 34 and the upper wall portion 29 are formed so as to be inclined upward as they approach the proximity direction. For this reason, rainwater or the like on the upper lip seal portion 34 is quickly discharged to the door outer panel 8.

Further, the inner wall portion 28 constituting the main body portion 26 of the outer side weather strip 25 includes a first vertical wall portion 35 extending downward from the corner portion 33 and a lower portion from the lower end portion of the first vertical wall portion 35. It is comprised by the inclination part 36 which inclines toward a near direction as it goes to, and the 2nd vertical wall part 37 extended toward the downward direction from the lower end part of the inclination part 36. As shown in FIG. In this way, by forming the inner wall portion 28 into a bent shape, the rigidity of the outer side weather strip 25 can be increased as compared with the case where the inner wall portion 28 is formed flat.

Further, the position of the window motor 63 of the elevating device 14 and the position of the rotation support portion 67 of the regulator unit 62 are set to positions that overlap with the position of the drain hole 39 formed in the outer side weather strip 25 in the vertical direction. However, it is offset in the horizontal direction from the position of the drain hole 39. For this reason, it is possible to prevent rainwater or the like flowing down from the drain hole 39 of the outer side weather strip 25 from dripping onto the wind motor 63 or the rotation support portion 67 of the regulator unit 62. Therefore, malfunction of the window motor 63 and the regulator unit 62 can be prevented.

The present invention is not limited to the above-described embodiment, and includes various modifications made to the above-described embodiment without departing from the spirit of the present invention.
For example, in the above-described embodiment, the case where the front engagement piece 55 and the rear engagement hole 46 of the inner side weather strip 51 are formed by cutting the core material 52a has been described. However, the present invention is not limited to this, and convex portions that can be engaged with the engagement holes 45, 46 are provided at positions corresponding to the engagement holes 45, 46 of the weather strip mounting portion 44 in the inner side weather strip 51. What is necessary is just to be provided.

In the above-described embodiment, the case where the front engagement hole 45 and the rear engagement hole 46 are formed in the weather strip attachment portion 44 has been described. However, the engagement holes 45 and 46 do not need to completely penetrate the weather strip mounting portion 44, and may have a shape that can receive the

engagement pieces

55 and 56 of the inner side weather strip 51. For example, the engagement holes 45 and 46 may be concave.

Further, in the above-described embodiment, four front engagement holes 45 and four rear engagement holes 46 are formed in the weather strip mounting portion 44, and each engagement hole 45 is formed in the inner-side weather strip 51. A case has been described in which the
