  However, as shown in Patent Document 1, a partition support partially provided in the vehicle front-rear direction with respect to the partition glass is welded to a flange at the lower end of the window frame (belt line portion) of the inner panel. When adopting a configuration that receives the lower part of the door, it is difficult to increase the rigidity of the door panel near the partition glass. In addition, there is a problem that water falls from the partition glass portion into the door, and water is applied to components such as a door latch to cause rust.

  In view of such problems, the present invention increases the rigidity of the partition support and has a drainage function, thereby improving the rigidity of the door panel near the partition glass and preventing water from splashing on the components inside the door. The object is to provide a vehicle door structure.

  In order to solve the above-described problems, a typical configuration of the present invention is that the weather strip attached to the outer periphery of the partition glass for the vehicle door is an inner panel of the vehicle door on each of the interior side and the exterior side of the partition glass. And a door structure of a vehicle including a partition support provided between the inner panel and the outer panel across the vehicle interior side and the vehicle exterior side, which is supported by the outer panel and further supports the lower end of the weather strip, The partition support has a flange that rises substantially vertically at the upper end and is joined to the inner panel, a downwardly inclined part that continues downward from the downwardly inclined part toward the outer panel, and continues downward from the downwardly inclined part along the outer panel. With a lower side extending to , And the and further comprising a bonding agent for bonding both between the outer panel and the lower portion.

  According to the above configuration, the partition support has a diaphragm shape having a flange, a downward inclined portion, and a lower side portion, so that the rigidity of the partition support can be increased, and thus the door panel (door panel assembly) near the partition glass can be improved. The rigidity can be increased, and deformation near the partition support including the outside handle and the latch can be suppressed at the time of a side collision, and the door latch can be prevented from being released and the door can be prevented from being opened.

  Also, the surface rigidity of the outer panel at the top of the outside handle can be improved, the feeling of stickiness when pressing this part of the outer panel when the door is closed, and the operation feeling of the outside handle are improved. Can do.

  Furthermore, the rigidity of the partition support can be further increased by joining the flange of the partition support to the joint flange (inner panel flange) of the inner panel.

  The rear part of the partition support may be connected to the pillar reinforcement of the vehicle door.

  According to the above configuration, by combining the rear part of the partition support with the pillar reinforcement, it is possible to improve the yield, rather than extending the pillar reinforcement and integrating it with the partition support. Parts costs can be reduced.

  The front portion of the partition support may be coupled to a beltline reinforcement provided along the beltline portion of the vehicle door.

  According to said structure, the rigidity of a belt line part can be improved by couple | bonding the front part of a partition support with a belt line reinforcement.

  It is preferable that the flange also wraps around the rear portion of the partition support and faces the pillar reinforcement of the vehicle door.

  According to said structure, since the rear part of a flange is facing the pillar reinforcement and forms the wall, it is prevented that water falls from the rear part of a partition support. Below the rear part of the partition support, there are a latch and a latch reinforcement, and it is possible to prevent the occurrence of rust due to water splashing on the components inside the door.

  A drainage groove that inclines toward the front side of the vehicle may be provided in the downward inclined portion of the partition support.

  According to the above configuration, the water falling from the drain hole of the partition weather strip is guided to the front side of the vehicle by the groove and dropped into the door in front of the latch, so that the latch is splashed with water. Can be prevented.

  A first drainage guide member extending in the front-rear direction may be fixed to the downward inclined portion of the partition support.

  According to the above configuration, the water falling from the drain hole of the partition weather strip is blocked by the drainage guide member, guided to the front of the vehicle, and dropped into the door on the front side of the latch. It is possible to prevent water from splashing on the surface.

  A second drainage guide member standing on the rear side of the partition support and before the pillar reinforcement of the vehicle door may be fixed.

  According to said structure, since the 2nd drainage guide member is standingly arranged before the pillar reinforcement, it is prevented that water falls from the rear part of a partition support. Such a configuration can also prevent the occurrence of rust due to water splashing on the components inside the door, such as the latch and the latch reinforcement.

  According to the present invention, the partition support can be made to have a drawn shape, thereby increasing the rigidity of the partition support, allowing the partition support to have a drainage function, thereby increasing the rigidity of the door panel near the partition glass. It is possible to provide a vehicle door structure that prevents water from splashing on components inside the door.

FIG. 3 is a partial perspective view, FIG. 3 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 4 is a cross-sectional view taken along line BB in FIG.

  As shown in FIGS. 1 and 2, a pair of left and right rear doors 1 (vehicle doors) (only the right side is shown in FIG. 1) is composed of an inner panel 2 and an outer panel 3 ( And a window frame sash 4 configured as shown in FIG. The partition glass 7 is held by the window frame sash 4 and the center sash 6 to form a fixed window. A door latch 8 is disposed in the rear lower part of the rear door 1 and below the window. The center sash 6 in FIG. 1 should be indicated by a solid line as in the case of the window frame sash 4, but is indicated by a two-dot chain line for the convenience of illustration of the partition support 10.

  A partition support 10 (see FIGS. 3 and 4) is provided between the inner panel 2 and the outer panel 3 as a member that supports the lower part of the partition glass 7 of the rear door of the vehicle. The partition support 10 is provided over the entire interior of the partition glass 7 in the vehicle front-rear direction along the belt line portion 5 (lower portion of the door window frame) of the door panel over the interior and exterior of the partition glass 7. As shown in FIG. 4, a partition weather strip 12 is attached to the outer periphery of the partition glass 7, and a center sash 6 is attached and fixed and sealed by being fitted into the window frame 4 of the door. Hereinafter, the partition weather strip 12 is also abbreviated as “weather strip 12”. The weather strip 12 has a vehicle interior side lip 12b and a vehicle interior outside lip 12a supported by the inner panel 2 and the outer panel 3 of the vehicle door 1 respectively on the interior side and the exterior side of the partition glass 7, respectively. The space between the panel 2 and the outer panel 3 is sealed.

  The lower side of the partition glass 7 is placed on and fixed to the partition support 10 via a weather strip 12. That is, the lower end of the weather strip 12 is further supported by the partition support 10. Several drain holes 12d (see FIG. 4) are provided at intervals on the lower side of the weather strip 12 so that water that has entered between the partition glass 7 and the partition weather strip 12 can be removed. It is supposed to be discharged through.

  The weather strip 12 shown in FIG. 4 has a cross section at a position where the drain hole 12d is provided and a wall of the drain hole 12d which is visible behind the drain hole 12d (a portion where the drain hole 12d of the weather strip 12 is not provided). ). A glass fitting groove 12c is formed on the inner circumference of the weather strip 12, and the outer circumference of the partition glass 7 is fitted into the glass fitting groove 12c. The drain hole 12d is formed in such a manner that the bottom of the glass fitting groove 12c is partially removed and a hole is formed through the glass fitting groove 12c and the outer peripheral side of the weather strip 12.

  Water enters the glass fitting groove 12c through the gap between the weather strip 12 and the partition glass 7 on the outside of the passenger compartment, but is discharged into the door through the drain hole 12d provided in the weather strip 12, so Water is prevented from overflowing from the gap between the weather strip 12 and the partition glass 7 and entering the vehicle interior side. The arrow W shown in FIG. 2 and FIG. 3 shows an example of the position of the drain hole 12d provided in the partition weather strip 12 (not shown).

  As shown in FIGS. 2 and 4, the partition support 10 has a flange 10 a formed to rise substantially vertically at the upper end portion, and is inclined downward in the vehicle width direction toward the outer panel 3 continuously to the flange 10 a. A downward inclined portion 10b, a lower side portion 10c extending downward along the inner surface of the outer panel 3 continuously from the downward inclined portion 10b, and an inwardly curved portion 10d formed at the lower end of the lower side portion 10c, The aperture shape has Here, the drawn shape refers to a shape in which the flange portion 10a, the downward inclined portion 10b, the lower side portion 10c, and the curved portion 10d are formed in a concave shape by drawing with a mold.

  A front end flange 10e is formed at the end portion of the partition support 10 on the front side of the vehicle. The front end wall 10g is provided in a portion surrounded by the front end flange 10e, the downward inclined portion 10b, the lower side portion 10c, and the side wall 10f that continues to the vehicle front side of the curved portion 10d, and the diaphragm is continuously closed. Is formed.

  The flange 10a is integrally joined to the inner panel flange 2a at the lower end of the window frame of the inner panel 2 (see FIG. 4). The flange 10a has a shape in which a wraparound portion 101 that wraps around to the end portion on the vehicle rear side (the rear portion of the partition support 10) is formed. The flange 10a, which is bent at a substantially right angle with respect to the descending inclined portion 10b, wraps around the corner of the descending inclined portion 10b, so that the flange 10a, the wraparound portion 101, and the descending inclined portion 10b are formed into a diaphragm shape. As described above, the partition support 10 is formed in a structure having high rigidity by being configured as a diaphragm shape as a whole.

  The lower part 10c of the partition support 10 is brought close to the inner surface of the outer panel 3 at a substantially constant interval, and the gap 14 between the lower part 10c of the partition support 10 and the outer panel 3 is filled by applying a bonding agent such as a mastic sealer 15 or the like. In addition, the partition support 10 and the outer panel 3 are bonded to each other via the mastic sealer 15.

  With this configuration, the surface rigidity of the outer panel 3 is improved. When the door is closed from the open state, the back side of the belt line part 5 of the outer panel 3 of the door is often pushed by hand. However, the improvement in surface rigidity eliminates the feeling of stickiness and improves the merchantability. In addition, an outside handle mounting portion 3a is provided on the outer surface of the outer panel 3 below the partition support 10 and an outside handle (not shown) is arranged, and an upper portion of the outside handle mounting portion 3a is arranged. By improving the surface rigidity of the outer panel 3, the rigidity of the outside handle mounting portion 3a is also improved, and the operation feeling of the outside handle is improved.

  The partition support 10 increases the rigidity of the entire door panel (door panel assembly) in the vicinity of the partition glass 7 of the belt line portion 5 in the vehicle longitudinal direction. Therefore, at the time of a side collision, the door panel does not bend at a portion where the partition support 10 is present, but is bent entirely at the front portion of the vehicle with respect to the partition support 10, and the outside handle disposed below the partition support 10. And the deformation of the latch 8 portion is suppressed, and the positional relationship of the connection between the outside handle and the latch 8 is maintained, so that the latch release is prevented and the door is prevented from being opened.

  Further, when the side collision occurs, local deformation of the outer panel 3 near the outside handle mounting portion 3a toward the vehicle interior side is also suppressed by the shape in which the lower side portion 10c of the partition support 10 is brought close to the outer panel 3, and the outer panel 3 Direction of the door latch release of the outside handle and the latch coupling member due to the movement of the outside handle mounting portion 3a to the vehicle interior side due to local deformation of the outside handle (by changing the positional relationship of the coupling between the outside handle and the latch 8) To prevent the door from opening.

  The rear end portion of the partition support 10 is joined to the pillar reinforcement 16 (see FIG. 2). Reference numeral J <b> 1 shown in FIG. 2 indicates a joint portion between the partition support 10 and the pillar reinforcement 16. In this embodiment, the mark “*” indicates a welding spot. The pillar reinforcement 16 is disposed along the vertical frame portion (pillar portion) of the window frame 4 of the door 1 and joined to the inner panel 2. Although the pillar reinforcement 16 and the partition support 10 may be configured as an integral structure, a separate structure as in the embodiment of the present invention can improve the yield compared to the integral structure. The front end portion of the partition support 10 is joined to the beltline reinforcement 11 (see FIG. 2), and the rigidity of the beltline portion 5 can be improved.

  A symbol J2 illustrated in FIG. 2 indicates a joint portion between the partition support 10 and the beltline reinforcement 11. Again, the mark “*” indicates a welding spot. The beltline reinforcement 11 is disposed along the lower end (beltline portion 5) of the window frame 4 of the door 1 from the front end portion of the partition support 10 to the entire lower portion of the window frame 4 on the vehicle front side. The beltline reinforcement 11 is joined to the inner panel 2 by welding together with the partition support 10, and is joined to the outer panel 3 via a mastic sealer in the same manner as the lower side portion 10c of the partition support 10 (FIG. Not shown).

  The partition support 10 and the pillar reinforcement 16 are joined together because they are separate structures, but due to the relationship between component accuracy and component assembly accuracy, a gap is set without joining the portions facing both in the vehicle longitudinal direction. . For this reason, since the terminal on the vehicle rear side of the downward inclined portion 10b of the partition support 10 and the pillar reinforcement 16 face each other in the vehicle front-rear direction, there is a gap between them. In this embodiment, the wraparound portion 101 of the flange 10a facing upward is arranged at the terminal of the partition support 10 on the rear side of the vehicle, and a wall facing the pillar reinforcement 16 is formed, so that the water of the partition weather strip 12 is The water discharged from the hole 12d is prevented from falling from the gap between the partition support 10 and the pillar reinforcement 16 on the vehicle rear side (see FIG. 3).

  As shown in FIG. 2, a drainage groove 17 that is inclined toward the front side of the vehicle is provided in the downwardly inclined portion 10 b of the partition support 10 in the vehicle front-rear direction. The groove 17 guides water discharged from the drain hole 12d of the partition weather strip 12 to the front side of the vehicle. Further, as described above, since the lower side portion 10c of the partition support 10 is brought close to the outer panel 3, even when the water discharged from the drain hole 12d of the partition weather strip 12 exceeds the groove 17, the outer panel. It is guided to the side 3 and can be dropped inside the door outside the vehicle compartment from the latch 8. In this way, by controlling the flow and falling position of water, it is possible to prevent water from splashing on components such as the latch 8 and the latch reinforcement 9 below the partition support 10 inside the door. Occurrence and functional failure can be prevented.

  5 and 6 show another embodiment of the present invention. In the present embodiment, a drainage guide member 20 (first drainage guide member) (FIG. 6) is attached in the vehicle front-rear direction of the upper surface of the partition support 10 in place of the groove 17 of the partition support 10 in the above embodiment. . The drainage guide member 20 is fixed to the descending inclined portion 10b of the partition support 10 so as to extend in the vehicle front-rear direction. The drainage guide member 20 guides water discharged from the drain holes 12d of the partition weather strip 12 to the front side of the vehicle. The downward inclined portion 10b is also inclined along the belt line portion 5 toward the vehicle front side.

  In addition, a pillar is provided along the terminal portion of the downward inclined portion 10b of the partition support 10 at the rear portion (end portion on the rear side of the vehicle) of the partition support 10 and in front of the pillar reinforcement 16 of the vehicle (front side of the vehicle). A drainage guide member 21 (FIG. 5) standing up against the reinforcement 16 is also fixed. With this drainage guide member 21 (second drainage guide member), even if there is no wraparound portion 101 of the flange 10a, the water discharged from the drain hole 12d of the partition weather strip 12 is discharged from the gap at the rear portion of the partition support 10. Prevent falling.

  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.
