Description
Technical Field
The present invention relates to an automotive door sealing material to be mounted on a door of an automobile.
Background
Conventionally, a sealing material for sealing a gap between a door of an automobile and a door opening of a vehicle body is attached to the door (for example, see patent documents 1 to 3). The sealant of patent document 1 is configured by connecting portions extending in the vehicle longitudinal direction along the upper edge portion of the sash, portions extending in the vertical direction along the rear vertical edge portion of the sash, and the like, and is attached over the entire periphery of the door. The cross section of the extrusion molded part extending along the upper edge part of the window frame is provided with a base part mounted on the window frame, an extrusion molded part sealing lip outside the vehicle compartment and an extrusion molded part sealing lip inside the vehicle compartment, which are integrally molded with the base part, and the sealing lips elastically contact with the vehicle body when the door is closed, thereby ensuring the sealing property. The rear end of the extrusion molding portion is continuous with a die molding portion which also includes a base portion attached to the window frame. The die forming portion is provided with a die forming portion seal lip continuous with the extrusion forming portion seal lip on the vehicle compartment inner side. Further, a support wall portion is provided in the vicinity of the rear end portion of the mold forming portion seal lip so as to extend in the vehicle compartment interior-exterior direction.
The sealing material of patent document 2 is vertically long and is attached to the rear end of the door. The sealing material has an upper end opening portion formed at an upper end portion thereof, a drain opening formed at a lower end portion thereof, and a continuous hollow portion extending from the upper end opening portion to the drain opening. The sealing material can guide water that has entered between the upper end of the door and the vehicle body into the hollow portion from the upper end opening of the sealing material and discharge the water from the drain opening.
The sealing material of patent document 3 is attached to the upper end portion of the sliding door. The sealing material is provided with a water receiving portion opened upward, and a drain hole is formed in the bottom of the water receiving portion.

Disclosure of Invention
However, in the case of the sealing material of patent document 1, since the extrusion molding section sealing lip extending along the upper edge portion of the window frame and the die molding section sealing lip are continuous in the front-rear direction, water that has entered between the upper end portion of the door and the vehicle body tends to flow toward the rear side along the extrusion molding section sealing lip and the die molding section sealing lip. The water flowing to the rear end of the seal lip of the mold forming portion may flow downward and contact the door opening/closing device. If water comes into contact with the door opening/closing device, the water may freeze in a cold region and may obstruct the opening/closing of the door.
Therefore, if a vertically long sealing material having an upper end opening, a hollow portion, and a drain opening is provided at the rear end portion of the door as in patent document 2, water that has entered between the upper end portion of the door and the vehicle body can be guided to a position below the door opening/closing device, and contact between the water and the door opening/closing device can be suppressed.
However, since the sealing material of patent document 2 is provided only at the rear end portion of the door, it is necessary to provide the sealing material having a hollow structure described in fig. 14 of patent document 2 at a position on the front side of the sealing material to ensure sealability. The sealing material having a hollow structure is likely to increase a reaction force acting on the door at the moment of closing the door, and as a result, a force required for closing the door is increased, which may deteriorate the door closing property. In view of this, if a seal structure based on a seal lip like the seal material of patent document 1 is used, deterioration of the door closing performance can be avoided, but there is a problem in patent document 1 that no countermeasure against water is taken for the door opening and closing device.
Further, in patent document 3, since the water receiving portion can receive the water flowing on the upper surface of the partition sealing material and discharge the water from the drain hole, it is considered that the water contacting the door opening/closing device can be greatly reduced. However, since the sealing material having the water receiving portion of patent document 3 is a member different from the partition sealing material, there is a possibility that water leaks from between the sealing material having the water receiving portion and the partition sealing material, and measures against the leaked water are required.
The present invention has been made in view of the above problems, and an object of the present invention is to make it difficult for water that has entered between an upper end portion of a door and a vehicle body to come into contact with a door opening/closing device without deteriorating door closing performance by a sealing material.
Here, in the present invention, the door opening and closing device is defined as a general term for three devices, that is, a door lock device, a door hinge device, and a door check device.
In order to achieve the above object, a first aspect of the present disclosure provides a sealing material for an automobile door, which is attached to a door that opens and closes a door opening portion formed in a side portion of a vehicle body of an automobile, and seals a gap between the door opening portion and the door, the sealing material for an automobile door comprising: an upper side seal portion mounted on an upper side portion of a frame of the door and extending in a vehicle front-rear direction along the upper side portion; and a vertical side seal portion integrally formed at one end portion of the upper side seal portion in the vehicle front-rear direction and extending downward along the vertical side portion of the frame, the upper side seal portion being provided with: a mounting base mounted on the upper edge; an outer seal lip disposed on an outer side of a vehicle compartment and extending in a vehicle front-rear direction, the outer seal lip being in elastic contact with the vehicle body when the door is closed; and an inner seal lip which is disposed further toward the vehicle interior side than the outer seal lip and extends in the vehicle front-rear direction, and which is in elastic contact with the vehicle body when the door is closed, wherein a water guide groove through which water that has entered between the outer seal lip and the vehicle body can flow in the vehicle front-rear direction is formed between the outer seal lip and the inner seal lip, wherein the upper portion of the vertical side seal portion has a water flow inlet that communicates with one end portion in the water guide groove in the vehicle front-rear direction, the lower portion of the vertical side seal portion extends to a position further downward than a door opening/closing device that opens and closes the door, and has a drain opening, and wherein a drain path that extends from the water flow inlet to the drain opening is formed inside the vertical side seal portion.
According to this structure, when the door is closed, the outer seal lip and the inner seal lip of the upper side seal portion elastically contact the vehicle body. In this case, since the outer seal lip and the inner seal lip are disposed at a distance from each other in the vehicle interior-exterior direction and are easily deformed by bending, the reaction force acting on the door at the moment of closing the door is smaller than that in the case of elastically contacting the sealing material having a hollow structure. Therefore, the door closeness is made good.
When the door is closed, the outer seal lip and the inner seal lip of the upper seal portion elastically contact the vehicle body, but water may enter between the upper end portion of the door and the vehicle body. The water entering the water guide groove between the outer seal lip and the inner seal lip flows in the front-rear direction of the vehicle. The water flowing to one end portion in the vehicle longitudinal direction in the water guide tank flows into a drainage path formed inside the vertical side seal portion from a water flow inlet formed at an upper portion of the vertical side seal portion. The water flowing into the drainage path is discharged from the drainage port located at a position lower than the door opening/closing device, and therefore does not contact the door opening/closing device. Since the upper edge seal portion and the vertical edge seal portion are integrally formed, water flowing from the water guide groove to the drain path does not leak in the middle, and thus contact between the water and the door opening/closing device can be suppressed.
According to a second aspect of the present disclosure, the door is a front door, and the drain opening is located on a rear side of the front door and further to a front side than the rear door hinge device and the rear door check device.
According to this configuration, since the water discharged from the water discharge port is discharged to a position further toward the front side than the rear door hinge device and the rear door check device, the water can be suppressed from contacting the rear door hinge device and the rear door check device.
According to a third aspect of the present disclosure, the water inflow port is formed to extend in the vehicle front-rear direction, an inner panel portion is provided at an edge portion of the water inflow port on the vehicle interior side, the inner panel portion extending upward and in the vehicle front-rear direction, and continuing to the inner seal lip.
According to this configuration, the water inflow port is made longer in the vehicle front-rear direction and the opening area is made larger, so that water can easily flow into the water inflow port. In this case, since the inner panel portion provided at the edge portion of the water inlet on the vehicle interior side is continuous with the inner seal lip, water flowing in the water guide groove between the outer seal lip and the inner seal lip is less likely to leak toward the vehicle interior side.
According to the fourth aspect of the present disclosure, in the vehicle interior surface of the inner panel portion, the protruding strip portion that protrudes toward the vehicle interior side and that elastically contacts the vehicle body when the door is closed extends continuously from the inner seal lip side toward one side in the vehicle front-rear direction.
That is, it is considered that water flows from between the upper end portion of the inner panel portion and the vehicle body to the cabin interior side of the inner panel portion when the door is closed. The water flowing toward the vehicle interior side of the inner panel portion can be guided to one end portion in the vehicle longitudinal direction by the ridge portion and discharged.
According to a fifth aspect of the present disclosure, an extension plate portion extending in one of the vehicle front-rear directions is provided at an upper portion of the longitudinal side sealing portion, and a hard plate material made of a material harder than a material constituting the longitudinal side sealing portion is provided so as to overlap with a vehicle interior surface of the extension plate portion, and the hard plate material extends upward from an edge portion of the water inflow port on the vehicle interior outer side.
According to this structure, the hard plate material can suppress deformation of the extension plate portion of the vertical side sealing portion. In this case, since the hard plate extends upward from the edge portion of the water inlet on the vehicle compartment outer side, the water flowing along the hard plate naturally flows into the water inlet by gravity and is discharged through the drainage path.
According to a sixth aspect of the present disclosure, the edge portion of the water inlet on the vehicle exterior side is disposed on the vehicle interior side of the extension plate portion apart from the extension plate portion, a part of the hard plate is disposed between the edge portion of the water inlet on the vehicle exterior side and the extension plate portion, and the edge portion of the water inlet on the vehicle exterior side is in contact with the surface of the hard plate on the vehicle interior side when the door is closed.
According to this configuration, the hard plate and the vertical side sealing portion can be integrated by disposing a part of the hard plate between the edge portion on the vehicle interior outer side of the water inlet and the extension plate portion. Further, when the door is closed, the edge portion on the vehicle interior side of the water inflow port comes into contact with the surface of the hard plate material on the vehicle interior side, so that water flowing along the hard plate material from above easily enters the water inflow port.
According to a seventh aspect of the present disclosure, the upper side seal portion is an extrusion-molded portion that is extrusion-molded, and is formed to have an extrusion-molded hollow portion extending in a vehicle front-rear direction, the vertical side seal portion has a die-molding portion integrally molded at an end portion of the upper side seal portion, the water flow inlet and an upper portion of the drainage path are formed in the die-molding portion, and the die-molding portion has: a die forming hollow portion communicating with the extrusion forming hollow portion; an upper core extraction hole for extracting the core molded in the hollow part formed by the mold; and a partition wall portion that partitions the mold forming hollow portion and the drainage path.
According to this configuration, the upper edge seal portion and the vertical edge seal portion can be integrated by integrally molding the die forming portion of the upper edge seal portion at the end portion of the upper edge seal portion that is extrusion molded. When the die forming portion is formed, the hollow portion can be formed by the core forming die, and after the hollow portion is formed by the die, the core can be pulled out from the die forming hollow portion. After the core is pulled out, the upper core pulling hole is opened, but since the die molding hollow portion and the drainage path are partitioned by the partition wall portion, water in the drainage path does not leak into the die molding hollow portion.
As described above, the outer seal lip and the inner seal lip of the upper side seal portion are elastically brought into contact with the vehicle body, so that the door closeability can be improved. In addition, in a state where the door is closed, water entering between the upper end portion of the door and the vehicle body flows in the vehicle front-rear direction through the water guide groove between the outer seal lip and the inner seal lip and flows into the drainage path of the vertical side seal portion, and therefore the water can be made to flow downward of the door opening/closing device, and therefore the water can be made to hardly contact the door opening/closing device.
Further, by disposing the water discharge port at a position further toward the front side than the rear door lock device and the rear door check device, it is possible to make it difficult for water to contact with the rear door lock device and the rear door check device.

The structures of the rear door hinge 311 and the rear door checker 315 are conventionally known.
(Structure of sealing Material for automobile door 1)
As shown in a part of fig. 5, the door 200 is attached with a door seal material 1 for an automobile that seals between the door 200 and the door opening 102. As shown in fig. 3, the sealing material 1 for an automobile door includes: a front edge sealing part 2 extending along the front edge part 221 of the frame 220; an upper edge sealing part 3 extending in the front-rear direction along an upper edge part 222 of the frame 220; a vertical edge sealing part 4 extending downward along the vertical edge part 223 of the frame 220; a front mold forming part 5; and a lower side sealing portion 6. The front edge seal portion 2 and the upper edge seal portion 3 are extrusion-molded portions integrally molded by extruding a material from a die (not shown), and have the same cross section from the front end portion to the rear end portion. The lower seal portion 6 extends downward along the front end portion of the door body 210 and extends to a front-rear direction intermediate portion along the lower end portion of the door body 210, and this lower seal portion 6 is also an extrusion molded portion. The front mold forming part 5 is a part connecting the front end of the front seal part 2 and the upper end of the lower seal part 6, and is a part formed by a mold (not shown) that performs an opening and closing operation.
Here, a boundary line between the lower seal portion 6 and the front side mold molding portion 5 is denoted by reference symbol L5, and a boundary line between the front side mold molding portion 5 and the front side seal portion 2 is denoted by reference symbol L4. The applicable materials for the front side seal portion 2, the upper side seal portion 3, the longitudinal side seal portion 4, the front side mold forming portion 5, and the lower side seal portion 6 are not particularly limited as long as they are rubber-like elastomers, but EPDM sponge rubber is preferable in the case of rubber, and foamed TPO or soft TPO is preferable in the case of thermoplastic resin.
The front edge sealing portion 2, the front side mold forming portion 5, and the lower side sealing portion 6 are not essential to the present invention, and may be omitted.
The vertical side sealing portion 4 includes a rear side die forming portion 7 formed by a die (not shown) that performs an opening and closing operation, a rear side extrusion forming portion 8 formed by extruding a material from a die (not shown), and a lower side die forming portion 9 formed by a die (not shown) that performs an opening and closing operation. The rear mold forming part 7 is formed to correspond to a boundary portion between the upper side portion 222 and the longitudinal side portion 223 of the frame 220, and a front side portion of the rear mold forming part 7 is connected to a rear end portion of the upper side sealing part 3. The rear extrusion molding section 8 extends in the vertical direction along the longitudinal side section 223 of the frame 220, and the upper portion of the rear extrusion molding section 8 is connected to the lower portion of the rear mold molding section 7. After the upper side sealing portion 3 and the rear side extrusion molding portion 8 are molded, the upper side sealing portion 3 and the rear side extrusion molding portion 8 are held by a mold for molding the rear side mold molding portion 7, and then the material of the rear side mold molding portion 7 is injected into the mold for molding, whereby the upper side sealing portion 3 and the rear side extrusion molding portion 8 can be integrally molded with the rear side mold molding portion 7.
After that, the rear extrusion molded part 8 is held by a mold for molding the lower mold molded part 9, and then the material of the lower rear mold molded part 9 is injected into the mold to be molded, whereby the rear extrusion molded part 8 and the rear mold molded part 9 can be integrally molded.
Here, a boundary line between the upper side seal part 3 and the rear side mold forming part 7 is denoted by reference symbol L1, a boundary line between the rear side mold forming part 7 and the rear side extrusion forming part 8 is denoted by reference symbol L2, and a boundary line between the rear side extrusion forming part 8 and the lower rear side mold forming part 9 is denoted by reference symbol L3.
Fig. 8 is a view showing a cross section of the upper seal portion 3 and a mounting structure. The upper side seal portion 3 has a mounting base portion 30 mounted to an upper side portion 222 of the frame 220. The mounting base 30 has a plate shape extending in the front-rear direction along the upper edge sealing material mounting plate portion 225a, and is fixed to the upper edge sealing material mounting plate portion 225a by a clip or the like, not shown. An outer wall portion 31 extending upward and also extending in the front-rear direction is formed on the vehicle-compartment outer side of the attachment base portion 30, and an inner wall portion 32 extending upward and also extending in the front-rear direction is formed on the vehicle-compartment inner side of the attachment base portion 30. The upper end of the outer wall 31 is continuous with the upper end of the inner wall 32. The upper seal portion 3 is provided with an inclined wall portion 33, and the inclined wall portion 33 extends obliquely from near the lower end portion of the outer wall portion 31 to the vertically intermediate portion of the inner wall portion 32, and also extends in the front-rear direction. Two extrusion hollow portions R1, R2 extending in the front-rear direction are formed by the attachment base portion 30, the outer wall portion 31, the inner wall portion 32, and the inclined wall portion 33.
A rear seal lip 34 is provided at the upper end of the outer wall portion 31 so as to project obliquely upward toward the vehicle compartment outer side. The back seal lip 34 elastically contacts the bent portion 224a of the outer panel 224 from the inside in a state where the upper edge seal portion 3 is attached to the upper edge seal attachment plate portion 225 a.
The upper seal portion 3 is provided with an extrusion portion outer seal lip 35 disposed on the vehicle compartment outer side and an extrusion portion inner seal lip 36 disposed further toward the vehicle compartment inner side than the extrusion portion outer seal lip 35. The extrusion portion outer seal lip 35 protrudes upward from the vicinity of the upper end portions of the outer wall portion 31 and the inner wall portion 32, extends in the front-rear direction, and elastically contacts the ceiling portion 120 that is a part of the vehicle body 101 when the front door 200 is closed. When the front door 200 is opened, it is formed to extend upward as shown by the imaginary line, and when the front door 200 is closed, if it is elastically contacted with the ceiling portion 120, it is pressed downward by the outer contact surface 120a of the ceiling portion 120 extending in the vehicle interior-exterior direction, and is elastically deformed, and is formed to be bent downward.
The extrusion portion inside seal lip 36 protrudes upward from the vertical direction middle portion of the inner wall portion 32 and extends in the front-rear direction, and elastically contacts the top portion 120 that is a part of the vehicle body 101 when the front door 200 is closed. When the front door 200 is opened, it has a shape extending toward the vehicle interior side as shown by the imaginary line, and when the front door 200 is closed, if it is elastically contacted with the ceiling portion 120, it is pressed toward the vehicle interior side by the inner contact surface 120b of the ceiling portion 120 extending in the vertical direction and is elastically deformed.
A water guide groove S is formed between the extrusion part outer seal lip 35 and the extrusion part inner seal lip 36. Since the extrusion part outer side seal lip 35 and the extrusion part inner side seal lip 36 extend in the front-rear direction, the water guide groove S is also constituted by a groove long in the front-rear direction. When the front door 200 is closed, the extrusion outside seal lip 35 elastically contacts the ceiling 120, but there is a possibility that external water enters between the extrusion outside seal lip 35 and the outside contact surface 120a of the ceiling 120. That is, if water enters between the top end of the front door 200 and the ceiling 120, the water flows into the water chute S, and the water flowing into the water chute S can flow in the front-rear direction.
Fig. 9 is a view showing a cross section of the rear extrusion molded part 8 and a mounting structure. The rear extrusion molding portion 8 has a mounting plate portion 80 mounted to the longitudinal edge portion 223 of the frame 220. The mounting plate portion 80 is a plate-like member that extends in the vertical direction along the vertical side sealing material mounting plate portion 225c and extends in the vehicle interior-exterior direction, and is fixed to the vertical side sealing material mounting plate portion 225c by a clip or the like, not shown. The rear extrusion molded part 8 has a peripheral wall part 81, and the peripheral wall part 81 is formed to extend from an edge part of the mounting plate part 80 on the vehicle compartment outer side to an edge part on the vehicle compartment inner side and bulge out to the rear side. The peripheral wall portion 81 is slightly recessed by elastically contacting the center pillar 111, which is a part of the vehicle body 101, when the front door 200 is closed.
A hollow portion R3 (described later in detail) defined by the mounting plate portion 80 and the peripheral wall portion 81 is provided in the rear side extrusion molded portion 8. In a state where the sealing material 1 for an automobile door is attached to the front door 200, as shown in fig. 3, the length of the rear extrusion-molded part 8 is set such that the lower portion of the rear extrusion-molded part 8 extends to a position lower than the door lock device 213. A drain port 82 communicating with the lower end of the hollow portion R3 is formed in the lower portion of the rear extrusion molded part 8, and the drain port 82 opens downward.
As shown in fig. 7, the mold molding section outer seal lip 70 is formed to protrude upward and extend in the front-rear direction on the vehicle compartment outer side of the rear mold molding section 7. The front end of the die-forming portion outer seal lip 70 is continuous with the rear end of the extrusion portion outer seal lip 35 of the upper side seal portion 3. The mold-formed-portion outside seal lip 70 elastically contacts the roof portion 120, which is a part of the vehicle body 101, when the front door 200 is closed.
A tube portion 70a extending in the up-down direction is provided on the vehicle interior side of the rear mold forming portion 7. The lower end of the cylindrical portion 70a is continuous with the upper ends of the mounting plate portion 80 and the peripheral wall portion 81 of the rear extrusion-molded portion 8. Thus, the internal space R4 of the tube portion 70a communicates with the hollow portion R3 of the rear extrusion molded part 8, and forms one drainage path R5 extending in the vertical direction inside the vertical side seal part 4. The lower end of the drain passage R5 communicates with the drain port 82, and the upper end of the drain passage R5 communicates with the water inlet 71 shown in fig. 7. Therefore, the drain path R5 extends continuously from the water flow inlet 71 to the drain port 82.
That is, a water inlet 71 is formed in the upper portion of the rear mold forming portion 7, and the water inlet 71 communicates with a rear end portion which is one end portion in the front-rear direction of the water guide groove S. The water flow inlet 71 is open upward, and is formed long in the front-rear direction. The water inlet 71 is located closer to the vehicle interior side than the mold forming section outer seal lip 70 in the vicinity of the lower end of the mold forming section outer seal lip 70. Since the water guide channel S is positioned in front of the water inlet 71, when water in the water guide channel S flows rearward, the water flows into the water inlet 71 from the front of the water inlet 71.
Both the vehicle interior edge 71a and the vehicle exterior edge 71b of the water inlet 71 extend in the front-rear direction. An inner panel 72 extending upward and in the front-rear direction is formed at an edge portion 71a of the water inlet 71 on the vehicle interior side. The front end of the inner plate 72 is continuous with the rear end of the extrusion inner seal lip 36 of the upper seal 3. Therefore, the water in the water guide channel S can be guided into the water inlet 71 through the inner plate portion 72 without exceeding the vehicle interior edge portion 71a of the water inlet 71.
The projecting strip 72a is provided on the cabin inner surface of the inner panel 27. The protruding portion 72a protrudes from the vehicle interior surface of the inner panel 27 toward the vehicle interior side, and extends continuously rearward from the extrusion portion inner side seal lip 36 side. The tip end of the protruding portion 72a is continuous with the upper end of the extrusion portion inner seal lip 36. The protruding portion 72a reaches the rear end portion of the tube portion 70a while descending obliquely so as to be located downward toward the rear side. As shown in fig. 10, when the front door 200 is closed, the inner panel portion 72 and the protruding strip portion 72a elastically contact the center pillar 111, which is a part of the vehicle body 101.
As shown in fig. 4, the rear mold forming portion 7 is provided with an extension plate portion 74 extending rearward. As shown in fig. 10, the surface of the extension plate portion 74 on the vehicle compartment outer side is in contact with the surface of the frame 220 on the vehicle compartment inner side at the vertical side portion 223. As shown in fig. 7, the edge portion 71b of the water inlet 71 on the vehicle compartment outer side is disposed on the vehicle compartment inner side of the extension plate portion 74 so as to be spaced apart from the extension plate portion 74. As shown in fig. 10, a through hole 74a is formed in the vertical direction intermediate portion of the extension plate portion 74. The through hole 74a is aligned with the corner outer panel sealing member mounting hole 225g of the inner panel 225.
An insert (hard plate) 50 made of a material harder than the material constituting the longitudinal side sealing portion 4 is provided so as to overlap the surface of the extension plate portion 74 on the vehicle interior side. As a material of the insert 50, for example, a material that is less deformable than a material constituting the rear die molding portion 7 such as polyacetal resin can be cited. As shown in fig. 12, the outer insert 50 includes a vertically long main plate 51, a front side protruding plate 52 protruding forward from an upper portion of the main plate 51, and a rear side protruding plate 53 protruding rearward of the main plate 51.
A pin portion 51a is formed on the surface of the main plate portion 51 on the vehicle compartment outer side. As shown in fig. 10, the pin portion 51a is inserted through the through hole 74a of the extension plate portion 74 and also inserted through the corner outer panel sealing material mounting hole 225g of the inner panel 225. This allows the extension plate 74 to be sandwiched between the outer insert 50 and the vertical side portion 223 of the frame 220.
As shown in fig. 6, the rear side projection plate portion 53 is formed so that the upper portion of the extension plate portion 74 is surrounded from the rear end portion thereof toward the vehicle cabin outer side. The upper portion of the extension plate portion 74 can be held by the rear side projection plate portion 53.
As shown in fig. 7 and the like, the front side protruding plate portion 52 is disposed between the vehicle cabin outer side edge portion 71b of the water inlet 71 and the extension plate portion 74. In this state, the front side protruding plate portion 52 extends upward from the vehicle cabin outer side edge portion 71b of the water inlet 71. As shown in fig. 10, when the front door 200 is closed, the inner panel portion 72 is elastically contacted with the right center pillar 111 and pressed outward in the vehicle compartment, so that the vehicle compartment outer edge portion 71b of the water inlet 71 is reliably contacted with the vehicle compartment inner surface of the main panel portion 51. When the front door 200 is closed, the vehicle interior side edge portion 71a of the water inlet 71 and the vehicle exterior side edge portion 71b are separated in the vehicle interior-exterior direction, and the water inlet 71 is not damaged.
As shown in fig. 11, the rear side mold forming part 7 has a mold forming hollow R7 and an upper core drawing hole 77 in the upper part. The die forming hollow R7 is also shown in fig. 4. The die molding hollow portion R7 communicates with the rear end portions of the extrusion molding hollow portions R1 and R2 of the upper side seal portion 3. The upper core drawing hole 77 is a hole for drawing out a core (not shown) formed in the die forming hollow portion R7, and opens downward in the rear die forming portion 7. By forming the die forming hollow portion R7, the difference between the rigidity of the upper portion of the rear die forming portion 7 and the rigidity of the upper side seal portion 3 can be reduced. The core is required for molding the mold molding hollow portion R7 in the rear mold molding portion 7. After the die forming hollow portion R7 is formed, the core is pulled out so that the upper core pulling hole 77 opens downward. However, since the rear mold forming section 7 has the drain passage R5, if the upper core extraction hole 77 remains open, there is a possibility that water in the drain passage R5 may leak from the upper core extraction hole 77.
Therefore, the rear die-forming portion 7 has a partition wall portion 78 that partitions the die-forming hollow portion R7 and the water discharge passage R5. The dividing wall 78 is also shown in fig. 4. The mold molding hollow portion R7 is located forward of the upper portion of the drain passage R5, and therefore the partitioning wall portion 78 extends in the upward and downward direction and the vehicle interior and exterior direction along the upper portion of the drain passage R5. Thus, the water in the drain path R5 does not leak from the upper core pulling hole 77 to the outside through the die forming hollow portion R7.
A lower core drawing hole 79 is formed in a lower portion of the rear mold forming portion 7. As described above, when the tube portion 70a of the rear die-forming portion 7 is die-formed, an intermediate core (not shown) is necessary as in the case of the die-forming of the hollow portion R7 described above. The center core molded on the inner surface of the tube portion 70a is pulled out, so that the lower center core pulling hole 79 opens forward on the outer surface of the tube portion 70 a. In this embodiment, the lower center drawing hole 79 is formed in a slit shape that is long in the vertical direction, but is not limited thereto. The lower core extraction hole 79 is disposed further toward the cabin outer side than the cabin inner side of the tube portion 70 a.
That is, as shown in fig. 6, when the longitudinal side sealing portion 4 attached to the longitudinal side portion 223 of the frame 220 is viewed from the rear side, the longitudinal side sealing portion 4 is inclined so as to be located more inward in the vehicle compartment as going upward, and is gently curved. This is because the longitudinal edge portion 223 of the frame 220 is formed so as to be located further toward the vehicle interior side than the upper side. Therefore, the drainage path R5 in the vertical side seal portion 4 is also inclined or curved in the same direction. The amount of water flowing into the drainage path R5 is not so large because it flows in while being sealed by the extrusion outer seal lip 35. Therefore, the water in the drain passage R5 flows toward the vehicle interior side than the center portion of the drain passage R5 in the vehicle interior-exterior direction. Since the lower core extraction hole 79 is disposed further toward the vehicle cabin outer side than the vehicle cabin inner side of the tube portion 70a, the lower core extraction hole 79 opens at a place where water in the drainage path R5 hardly flows. Therefore, even if the lower core extraction hole 79 is not completely closed, the water flowing through the drain path R5 hardly leaks from the lower core extraction hole 79.
(effects of embodiment)
As described above, according to the present embodiment, when the front door 200 is closed, the extrusion outside seal lip 35 and the extrusion inside seal lip 36 of the upper side seal portion 3 elastically contact the ceiling portion 120, as shown in fig. 8. At this time, since the extrusion portion outer side seal lip 35 and the extrusion portion inner side seal lip 36 are disposed at a distance from each other in the vehicle interior and exterior direction and are easily deformed by bending, a reaction force acting on the front door 200 at the moment of closing the front door 200 becomes smaller than that in the case of elastically contacting the sealing material having a hollow structure. Therefore, the door closeness becomes good.
When the front door 200 is closed, the extrusion outside seal lip 35 and the extrusion inside seal lip 36 of the upper side seal portion 3 elastically contact the ceiling portion 120, but water may enter between the extrusion outside seal lip 35 and the ceiling portion 120 as indicated by an arrow W1 in fig. 7. The immersed water flows into the water guide groove S between the extrusion portion outer side seal lip 35 and the extrusion portion inner side seal lip 36. The water flowing into the water guide channel S flows rearward in the water guide channel S as indicated by an arrow W2. The water flowing backward through the water guide channel S flows into the water discharge path R5 formed inside the vertical side sealing portion 4 from the water flow inlet 71 formed in the upper portion of the vertical side sealing portion 4 as indicated by an arrow W3. The water flowing into the drainage path R5 is discharged from the drainage port 82 located below the door lock device 213 as indicated by an arrow W4 in fig. 3, 13, and 14, and therefore does not come into contact with the door lock device 213.
Further, since the upper edge seal portion 3 is integrally formed with the vertical edge seal portion 4, the water flowing from the water guide groove S to the water discharge path R5 does not leak in the middle, and thus the water can be prevented from contacting the door lock device 213.
Further, as illustrated in fig. 8 and 7, since the water that has entered is discharged as indicated by arrows W1 → W2 → W3 → W4, the water W0 that has fallen from the rear mold forming section 7 as illustrated in fig. 3 can be reduced, and the rear door hinge device 311 and the rear door check device 315 can be prevented from directly contacting the water.
Further, as shown in fig. 13 and 14, since the drain port 82 is disposed at a position further forward than the rear door hinge device 311 and the rear door check device 315, the rear door hinge device 311 and the rear door check device 315 can be made more difficult to contact with water.
As shown in fig. 7, since the water inflow port 71 is long in the front-rear direction, the opening area is large, and water easily flows into the water inflow port 71. In this case, since the inner plate portion 72 provided at the vehicle interior edge portion 71a of the water inlet 71 is continuous with the extrusion portion inner seal lip 36, the water flowing in the water guide channel S between the extrusion portion outer seal lip 35 and the extrusion portion inner seal lip 36 is less likely to leak into the vehicle interior.
When the front door 200 is closed, it is considered that water flows from between the upper end of the inner panel 72 and the right center pillar 111 toward the vehicle interior side of the inner panel 72 as indicated by an arrow W5. The water flowing toward the vehicle interior side of the inner panel 72 can be discharged rearward through the projecting strip 72a as indicated by arrow W6.
When the front door 200 is closed, as indicated by an arrow W7, water is supposed to flow from the upper end of the insert 50 along the surface of the front side panel 52 of the insert 50 on the vehicle interior side. In this case, since the front side projection plate portion 52 of the outer insert 50 extends upward from the vehicle interior side edge portion 71b of the water inlet 71, the water flowing along the front side projection plate portion 52 naturally flows into the water inlet 71 by gravity and is discharged through the drainage path R5.
However, the above-described embodiments are merely illustrative in all respects and are not to be construed in a limiting sense. Further, all modifications and variations falling within the equivalent range of the scope of the claims are within the scope of the present invention.
As described above, the sealing material for automobile doors according to the present invention can be used for front doors and rear doors.
