Description

  The present invention relates to a water drainage structure for an automotive door glass run which is disposed on the inner periphery of a door sash and has a function of receiving the door glass when the door glass is closed and sealing the outside of the vehicle interior, and more particularly, a corner portion of the door sash. It is related with the drainage structure in the corner type | mold molded part corresponded to.

  As is well known, the door glass run arranged on the inner periphery of the door sash of an automobile is composed mainly of a glass run main body having a substantially channel cross-section that will receive the door glass when the door glass is closed. Seal lips are provided at the indoor and outdoor opening edges of the glass run body to prevent rainwater and the like from entering with the seal lip reaction force.

  On the other hand, when a car was washed under high water pressure with the spread of high-pressure car wash machines in recent years, the ingress of water droplets cannot be completely prevented only by the reaction force of the outdoor seal lip. The water may accumulate on the back side of the outdoor seal lip after getting over. When such a phenomenon that water accumulates on the back side of the outdoor seal lip occurs in the portion corresponding to the upper side of the door sash, the water flows in the longitudinal direction of the door glass run, and then passes through the corner mold forming portion. A corner type in which the flow direction changes greatly when the amount of drainage that can be retained on the back side of the outdoor seal lip is exceeded, although it flows along the portion of the glass run that corresponds to the vertical side of the door sash (the portion along the pillar). Such water will infiltrate indoors at the molding part.

  In particular, the corner-shaped molded part is less likely to have a reaction force of each seal lip than the general part regardless of whether it is an indoor-side seal lip or an outdoor-side seal lip. Since a slight level difference will occur at the joint between the molded part and the general part, water tends to enter the indoor side over the indoor seal lip.

As a countermeasure for draining such water, particularly as a countermeasure for draining water accumulated in the portion corresponding to the upper side of the door sash in the door glass run, for example, as described in Patent Document 1, from the corner mold forming part of the door glass run For example, a tube portion is formed on the bottom surface portion of the glass run main body portion over a portion corresponding to the vertical side portion of the door sash (a portion along the pillar) to actively drain water.

  FIGS. 1 to 7 are views showing a more specific embodiment of the present invention. In particular, FIG. 2 shows a vehicle in which the door glass run 3 at the corner portion a of the right front door 1 of the automobile shown in FIG. FIG. 3 is a perspective view of FIG. 2 viewed from the rear side (right side), FIG. 4A is a right side view of FIG. 2, and FIG. A sectional view taken along line AA in A) is shown. The front door 1 is referred to as a so-called press door or full press door in which the sash frames 2a and 2b of the door sash 2 are integrally formed with the door outer panel and door inner panel of the door body as shown in FIGS. Of the type.

  As shown in FIGS. 2 to 4, the door glass run 3 arranged along the inner periphery of the door sash 2 of the front door 1 is generally a glass run general part that is along the upper side 2 </ b> A of the door sash 2. 3A and the glass run general part 3B which will be along the vertical side part 2B of the door sash 2 and the corner mold forming part 3C which will be interposed between the glass run general parts 3A and 3B. , 4b are joined and integrated. The glass run general portions 3A and 3B are extruded, for example, with a uniform cross-sectional shape as shown in FIG. 5, whereas the corner mold formed portion 3C is formed between the end portions of the glass run general portions 3A and 3B. Are molded so as to join together, and the cross-sectional shape is, for example, as shown in FIGS.

  As shown in FIGS. 5 to 7, such a door glass run 3 sandwiches an elevating type door glass G at an opening edge of a glass run body portion 4 having a substantially channel-shaped cross section that forms a glass receiving space R. An outer seal lip 5 that is positioned outside the vehicle interior and an inner seal lip 6 that is positioned inside the vehicle interior are formed so as to protrude obliquely inward, and are opposite to the inner seal lip 6. On the side, a panel lip 7 is formed so as to protrude. The panel lip 7 is brought into elastic contact with the sash frame 2b while the door glass run 3 is fitted to the sash body 2c of the door sash 2, and the holding lips 8 and 9 are engaged with the locking projections 10 and 11 on the sash body 2c side. The positioning is maintained by combining them.

  5-7, the door sash 2 includes an inner sash frame 2b integrated with the door inner panel, an outer sash frame 2a integrated with the door outer panel, and a sash body 2c having a substantially channel cross section. As shown in FIG. 2, the sash body 2c on the upper side 2A side of the door sash 2 and the sash body 2c on the vertical side 2B side of the door sash 2 are both corner-shaped molded parts 3C. The part corresponding to is interrupted, and both are substantially discontinuous.

  As shown in FIGS. 3, 4, and 7 in addition to FIG. 2, the vertical side portion corresponding portion 12 that extends along the vertical side portion 2 </ b> B of the door sash 2 in the corner mold forming portion 3 </ b> C has a glass receiving space R side. A rectangular drain hole 13 is formed through the bottom surface of the glass run body 4 so as to provide a drainage function from the vertical side portion 12 to the back side of the vertical side portion 12 (in FIGS. Despite this, in order to make the position of the drain hole 13 easier to understand, the corresponding part is hatched). Further, a drip channel 14 having a substantially channel cross section inclined integrally from the glass receiving space R side to the back side of the vertical side portion 12 is integrally formed in the lower half portion of the drain hole 13 as a guide member. 2 (Note that in FIGS. 2 to 4, although not a cross-sectional view, the corresponding part is hatched to make the position of the drip channel 14 easier to understand). Since this drip channel 14 forms a part of the drain hole 13 and is open on the upper surface side, as will be described later, water droplets that flow down the bottom surface in the glass run body 4 at the vertical side portion 12. It has the function to guide to the back side of the vertical side portion equivalent portion 12 while actively collecting. As shown in FIGS. 4 and 7, when the door glass G is raised, the edge of the door glass G is set so as to positively contact or elastically contact the drip channel 14. The drip channel 14 also has a function of compensating for a decrease in rigidity of the bottom surface of the glass run main body 4 due to the formation of the drain hole 13.

  A so-called bowl-like wind noise prevention wall portion 15 is formed so as to protrude above the drainage hole 13 on the back surface of the vertical side portion corresponding portion 12, and this wind noise prevention wall portion 15 is used for water during vehicle travel. It has a function of preventing the entry of traveling wind from the hole 13 and the generation of wind noise associated therewith.

  Further, a baffle rib 16 is formed to protrude along the longitudinal direction at one side portion close to the drain hole 13 on the back surface of the vertical side portion 12 and the upper end of the baffle rib 16 is a wind noise prevention wall. While the lower end of the baffle rib 16 is gradually displaced to the outside of the chamber with a slanted wall 16a, it is finally at a position corresponding to the joint line 4b and corresponding to the vertical side. It converges at the most outdoor portion of the back surface of the portion 12.

  The wind noise prevention wall portion 15 and the baffle rib 16 are both set at the same height. When the door glass run 3 is correctly positioned and held on the door sash 2 as shown in FIG. Both the portion 15 and the baffle rib 16 are in pressure contact with the inner bottom surface of the sash body 2c.

  Here, for example, in the glass run general part 3A along the upper side 2A of the door sash 2 in the door glass run 3, water accumulates on the back side of the outer seal lip 6 (the groove-shaped space formed between the outer seal lip 6 and the glass run main body 4). In this case, the water flows in the longitudinal direction and then drains to the glass run general part 3B side along the vertical side part 2B of the door sash 2 through the equivalent part of the corner mold part 3C. When the amount of drainage that can be held in the back side space of the outer seal lip 6 exceeds the amount of drainage that can be held in the corner mold part 3C whose direction changes greatly, the interior side of the glass receiving space R is closer to the indoor side, for example, the back side of the inner seal lip 5. As mentioned above, water may intrude until the end. In particular, in the corner mold forming part 3C, the reaction forces of the outer and inner seal lips 5 and 6 tend to be insufficient compared to the glass run general parts 3A and 3B. In some cases, the lip 6 may pass over the sealing surface of the lip 6 and enter the indoor side, and the water may pass over the sealing surface of the inner sealing lip 5 and enter or drop into the indoor side.

  Therefore, in the drainage structure of the door glass run 3 according to the present embodiment, at least the rainwater or the like that has entered the interior side of the corner molding portion 3C from the seal surface of the outer seal lip 6 is actively collected by the drip channel 14. In addition, the water is to be drained from the drain hole 13 to the back side of the vertical side portion 12.

  More specifically, at the position corresponding to the drain hole 13 in the vertical side portion corresponding portion 12 of the corner mold forming portion 3C, the water flowing down from above is opened upward while greatly changing the flow direction. It is collected by the drip channel 14 and drained from the drain hole 13 to the back side of the vertical side portion corresponding portion 12. At the same time, when the door glass G is rising, when the door glass is closed, as shown in FIG. 4B, the edge of the door glass G is pressed against or pressed against the drip channel 14 as if it interfered with the drip channel 14. Therefore, the water D flowing down along the edge of the door glass G is also collected by the drip channel 14 and drained from the drain hole 13. As a result, it is possible to prevent water leakage from the corner mold part 3C to the indoor side.

  On the back side of the vertical side portion 12, the wind noise prevention wall portion 15 and the baffle rib 16 projecting from the vertical side portion 12 are pressed or elastically contacted or elastically contacted with the sash body 2 c of the door sash 2. Since the passage is formed, the water drained from the drain hole 13 flows down while being guided by the baffle rib 16 forming the tubular passage. In particular, at the lower end portion of the baffle rib 16, the portion is gradually displaced to the outside of the chamber as the inclined wall portion 16 a, so that the water drained from the drainage hole 13 as described above finally becomes the glass run general portion 3 </ b> B. In the space surrounded by the sash body 2c, the water is drained to the outdoor portion. This makes it possible to prevent re-entry of the water once drained into the room.

  Further, since a so-called bowl-like wind noise prevention wall portion 15 is set on the back side of the vertical side portion equivalent portion 12 above the opening portion of the drainage hole 13, the drainage hole associated with vehicle travel is provided. It is possible to prevent the wind from 13 and the accompanying wind noise from occurring.

  8 to 12 show a second embodiment of the present invention, and the same reference numerals are given to the portions common to the first embodiment described above.

  In the second embodiment, the baffle rib 16 and the wind noise prevention wall portion 15 shown in FIGS. 3 and 4 are completely integrated on the back side of the vertical side portion corresponding portion 12 of the corner mold portion 3C. Therefore, the drain pipe 17 is formed as a tubular passage having a rectangular closed cross-sectional structure.

  The drain pipe 17 communicates with the drain hole 13 at its upper end so that the drain hole 13 is the inflow side, while the discharge hole 18 at its lower end is connected to the sash body on the vertical side 2B side of the door sash 2. It faces the back side of 2c. Further, on the inner bottom surface side of the drain pipe 17, the bottom wall surface of the drip channel 14 is inclined as it is extended downward, and as a result, the drain pipe 17 gradually opens its effective opening as it goes downward. It has a shape that reduces the area. In particular, as shown in FIGS. 10 and 12, the lower end portion of the drain pipe 17 is extended to a position below the upper end of the sash body 2c, and the lower end portion is extended to the sash body 2c as shown in FIGS. It is locked so that it rides on the upper end of the.

  In addition, the inclined wall part 17a of the upper end of the drain pipe 17 has a function equivalent to the wind noise prevention wall part 15 of 1st Embodiment.

  Therefore, according to the second embodiment, not only the drainage function similar to that of the first embodiment described above is exhibited, but also the water drained from the drain hole 13 is drained from the drain pipe 17. Since the drainage efficiency is improved, the drainage pipe 17 is positioned so that the lower end of the drainage pipe 17 rides on the upper end of the sash body 2c. Water can be reliably drained to the outside of the sash body 2c, and re-entry of the water after draining into the indoor side can be more reliably prevented. In addition, since the lower end portion of the drain pipe 17 is positioned by being locked to the upper end portion of the sash body 2c, the water from the drain pipe 1 can be drained with directivity. There is an advantage that it can be drained to the outdoor side by guiding it to the drain hole.
