[0001]

[Industrial applications]

 The present invention relates to a roof structure for vehicles such as passenger cars, trucks, and trains having a sunroof.

[0002]

[Prior Art]

 Conventionally, roof drainage structures as shown in FIGS. 8 and 9 have been proposed. FIG. 8 is a perspective view of a vehicle equipped with a sunroof. A roof opening 3 is provided substantially in the center of a roof panel 2, and a sunroof glass 4 made of transparent or translucent glass is provided in the roof opening 3 by a supporting structure (not shown). The sunroof glass 4 is attached so that the outer peripheral edge of the sunroof glass 4 opens and closes the opening 3 of the roof panel 2 via the outer weather strip 13. The sunroof glass 4 can be tilted up with its front side as a fulcrum by a support structure (not shown). Further, the outer side roof rail 8 and the pillar rail 9 are welded to the roof panel 2 so as to be smoothly connected to each other in appearance. As shown in FIG. 9 (a sectional view taken along the line IX-IX in FIG. 8) from the sunroof glass 4 to the tailgate 6, an outer weather strip 13 is attached to the rear end of the sunroof glass 4, The glass seal portion 3a ′ of the rear end inner peripheral wall 3a of the roof opening portion 3 of the roof panel 2 comes into contact with the tailgate 6 via a rear roof panel 2r, which will be described later, and is connected to the tailgate 6 in appearance. The rear roof panel 2r constituting the roof 1 on the vehicle rear side of the sunroof glass 4 is bent downward so as to form the rear end inner peripheral wall 3a of the roof opening 3 on the vehicle front side. 4 that bends forward so as to enter under 4 and receives and drains water from the outside of the vehicle that enters through the gap between the outer weather strip 13 of the sunroof glass 4 and the inner peripheral wall 3a of the rear end of the roof opening. A receiving portion 2r1 is formed. At the rear of the vehicle body, the rear roof panel 2r is bent downward so as to be convex, and further bent under the tailgate 6, and the end portion is further bent in the tailgate direction. A bent flange 2r2 is provided to form a drainage portion 2r3 of the roof panel 2r. In addition, as described above, the water receiving portion 2r1 of the roof panel 2r is formed so that the closed rear cross section is formed by the rear roof panel 2r that is convex upward in the vehicle and the rear roof rail 11 that is an inner member on the vehicle body rear side of the roof. In the drainage section 2r3, spot welding is performed as indicated by 14a and 14b, respectively. An inner weather strip 15 is attached to a front end portion 15 'of the vehicle body of the water receiving portion 2r1 so as to contact the sunroof glass 4, and a weather strip 7 for a tailgate is attached to a flange 2r2 at a rear end portion of the vehicle body of the drainage portion 2r3. Are attached so as to abut the tailgate 6. A plurality of drain pipes 16 are fixed to the roof panel 2 by welding so as to bridge through the convex space of the roof panel 2 between the water receiving portion 2r1 and the drainage portion 2r3 of the roof panel 2r.

Rainwater is sealed by the outer weather strip 13, but when the glass seal portion 3a ′ is detached from the roof panel 2 such as when the sunroof glass 4 is tilted up, or when it is sealed by the glass seal portion 3a ′. If it cannot be drained, rainwater will enter the water receiver 2r1. If the amount of infiltrated water is relatively small or the momentum is small, it is drained to the drainage section 2r3 by the drain pipe 16 and is connected to the drainage groove on the outer periphery of the trunk room (not shown) arranged on the tailgate side. Drained to the rear of the vehicle. In addition, even if a large amount of water has entered and the momentum is so great that the drain pipe 16 cannot be used to completely drain the water at once, and the water has come in front of the water receiving portion 2r1, the inner weather strip 15 causes the water receiving portion 2r1 to drain. The water is stopped at, preventing water from invading into the passenger compartment A , and finally drained by the drain pipe 16.

[0004]

[Problems to be solved by the device]

However, in such a conventional drainage structure, as shown in FIG. 9, a relatively large amount of water intrudes from the glass seal portion 3a ′, and the drain pipe 16 is increased in number due to the strength restriction of the roof panel 2. If the diameter cannot be increased, the diameter of the drain pipe 16 is also small and the number of the drain pipe 16 is about 2. Since the drain pipe 16 has a relatively long overall length, it may not be possible to drain it all at once. If it becomes clogged due to dirt or corrosion, the drainage performance will deteriorate further, and the water that cannot be drained will spill around in front of the water receiving portion 2r1 of the vehicle body, and due to the large amount of water pressure and the vibration of the vehicle, the inner weather strip 15 There is a risk of passing through the space between the mounting portion 15 ′ and the tip of the water receiving portion 2r1 and entering the passenger compartment A. In addition, during production and assembly, the drain pipe 16 must be welded and assembled before painting the body, which complicates the process, and if the drain pipe 16 is corroded by rainwater or the like, replacement is very troublesome. There is a problem that is. Further, since the spot dents 14a are visible through the sunroof glass 2, there is room for improvement in terms of appearance.

The present invention has been made in view of these problems, and a roof panel at the rear of the sunroof is recessed toward the passenger compartment to form a roof extension, and an SMC (Sheet Sheet) is formed on a roof member of the recessed portion. By using a rear roof panel made of resin such as Molding Compound) material and devising a drainage route, a drain pipe is not required and the ingress of water into the inner weather strip is blocked as much as possible to ensure drainage. It aims at providing the roof drainage structure which does.

[0006]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. Members that are substantially the same as those of the conventional structure shown in FIGS. 8 and 9 are designated by the same reference numerals.

In a vehicle equipped with a sunroof as shown in FIG. 1, the roof 1 is composed of a roof panel 2 and a sunroof, and a roof opening 3 is provided substantially in the center of the roof panel 2 and the front side of the vehicle body is provided. As shown in FIG. 3, the inner peripheral wall 2a and the outer peripheral wall 2b bend the roof panel 2 downward so that the roof opening 3 on the F side and the side S does not include the rear roof panel and the rear inner peripheral wall 2a. The U-shape (plan view) constitutes the base material of the roof panel. A sunroof glass 4 made of transparent or translucent glass is mounted in front of the roof opening 3 so that the sunroof glass 4 can be tilted up with its front side as a fulcrum by a support structure (not shown). .. The structure of the roof opening 3 on the rear side of the vehicle body is such that the water receiving portion 5a extends downwardly from the left and right inner peripheral walls 2a and is inclined rearward, and the rear end of the water receiving portion 5a enters under the tailgate 6. A roof extension 5 is formed integrally with the roof panel 2 on which the drainage portion 5b is extended. The drain portion 5b of the roof extension 5 is provided with a bent flange 5c so as to face the back surface of the tailgate 6, and is in contact with the tailgate 6 via the weatherstrip 7 for the tailgate. Further, a rear roof panel 2R is formed, the front end of which is mounted so as to substantially coincide with the front end of the roof extension 5 and which is fitted between the left and right side roof panels 2c and 2d on the side of the vehicle body. The roof panel 2 includes a front roof panel 2F, left and right side roof panels 2c and 2d, and a rear roof panel 2R.

Further, as shown in FIG. 3, the flanges (a) at the rear ends of the left and right outer side roof rails 8 are the flanges (a ′) at the front ends of the left and right pillar rails 9 and the upper parts of the left and right pillar rails 9. The side flanges (b) and (c) are the flanges (b ') and (c') at the left and right ends of the roof extension 5, and the flanges (d) of the left and right side pillar rails are the left and right roofs. The flanges (e) of the left and right outer side roof rails 9 which are welded and connected to the flanges (d ') extending to the rear of the lower surfaces of the panels 2c and 2d so as to be smoothly connected to each other, and the flanges (e) of the left and right outer side roof rails 9 connected as described above are the above The outer roof panels 2c, 2d are welded to the peripheral walls 2b 'of the two roof panels 2c, 2d so as to be smoothly connected with each other, and as shown in FIG. Note that, as shown in FIG. 6, the cross section of the left and right side portions of the tailgate of the pillar rail 9 is formed with a groove 9a that opens upward.

As shown in FIGS. 3 and 7, a resin member such as SMC (Sheet Molding Compound) material is used for the rear roof panel 2R which is a constituent member of the roof panel 2 and is different from the roof panel 2. The cross section formed on the body as viewed from the vehicle width direction has a shape of approximately five over the entire width of the sunroof. The rear roof panel 2R is bent toward the front side of the vehicle body so as to go under the sunroof glass 4 one step below itself, and further, the front portion 5d of the roof extension 5 and the front portion 5d are substantially parallel to each other while maintaining the desired space 10. The water immersion portion 2R1 formed by extending to the vicinity of the front end of the vehicle body, and the water draining flange 2R2 are provided at the front end portion of the water immersion portion 2R1 so as to stand upright. In addition, an outer wall 2R3 that can be bent toward the vehicle compartment side A is provided at the rear part of the vehicle body of the rear roof panel 2R, and a tip portion 2R4 of the outer wall 2R3 has a gap 2R5 with which the roof extension 5 and rainwater flow. In addition, the rear end walls 2c ', 2d' of the left and right side roof panels 2c, 2d and the outer wall of the rear roof panel 2R are arranged so as to have the same appearance. (See Fig. 1). Also, the D near the inflection point between the flooded portion 2R1 inclined toward the rear of the vehicle body and the front wall 2R9, weep holes 2R6 is is provided with several positions, the cabin side A of the flooded portion 2R1 is the As shown in FIG. 3, several bead-shaped mounting portions 2R10 extending in the axle direction are provided. However, the positional relationship between the water immersion portion 2R1 and the water drainage hole 2R6 may not be the same as in the above embodiment as long as the water drainage hole 2R6 is provided near the lowest point of the water immersion portion 2R1.

Next, a mounting structure of the rear roof panel 2R will be described. As shown in FIG. 4 (a cross-sectional view taken along the line IV-IV in FIG. 1), the rear roof panel 2R has a mounting portion 2R10, and a front portion 5d of the roof extension 5 and a rear roof rail 11 which is an inner member on the vehicle body rear side of the roof. The submerged portion 2R1 except the mounting portion 2R10 maintains a space 10 with the front portion 5d of the roof extension 5. Further, as shown in FIG. 5 (a sectional view taken along the line VV in FIG. 1), the left and right end portions 2R7, 2R8 of the rear roof panel 2R in the vehicle width direction are formed with the inner peripheral wall 2a of the left and right side roof panels 2c, 2d. The rainwater W that is in contact with and infiltrates between the two members falls on the roof extension 5 as shown in FIG. 7 and is drained from the drain portion 5b.

As shown in FIG. 7 (a sectional view taken along the line VII-VII in FIG. 1), an outer weather strip 13 is attached to an end portion of the sunroof glass 4, and is attached to a front wall 2R9 of the rear roof panel 2R. The glass seal portion 2R9 'is configured to come into contact with the tailgate 6 so that the tailgate 6 is smoothly connected in appearance. Further, the roof extension 5 and the rear roof rail 11 are spot-welded near the mounting portion 5d for fixing the rear roof panel 2R of the roof extension 5 and the drainage portion 5b like 14a and 14b, respectively. An inner weatherstrip 15 is attached to the front end of the vehicle body of the water receiving portion 5a of the roof extension 5 so as to abut against the sunroof glass 4, and a tailgate weatherstrip 7 is attached to the flange 5c. 6 is attached so as to abut. The flooded part 2R1 of the rear roof panel 2R maintains the space 10 with the front part 5d of the roof extension 5 as described above, and the tip 2R4 is also attached so as to maintain the drainage part 5b and the space 2R5. ing.

The rainwater is sealed by the outer weather strip 13, but when the glass seal portion 2R9 ′ is detached or cannot be completely sealed by the glass seal portion 2R9 ′ when the sunroof glass 4 is tilted up, the rainwater is flooded. It invades 2R1. When the amount of invading water is relatively small or the momentum is small, the water is drained to the drain portion 5b of the roof extension 5 through the drain hole 2R6, and the pillar outer rail 9 disposed on the side of the tailgate 6 is removed. It is drained to the rear side of the vehicle body by connecting the groove portion 9a. When the amount of water that has entered is large and the force of the water is large, the water is not drained from the drain hole 2R6 at once, but is blocked by the drain flange 2R2 and finally drained from the drain hole 2R6. Further, even when water intrudes so hard that it crosses over the drain flange 2R2, it is blocked by the inner weather strip 15, and there is a space 10 between the front portion 5d of the roof extension 5 and the flood portion 2R1 of the rear roof panel 2R. Therefore, the roof extension 5 is connected to the water receiving portion 5a and the drainage portion 5b, and the groove portion 9a of the pillar rail 9 arranged on the side portion of the tailgate 6 is connected to the rearward side of the vehicle body as shown in FIG. To be done.

Therefore, by taking such a drainage path, the ingress of water into the inner weather strip 15 is blocked as much as possible, so that not only the drain pipe 16 is required, but also the drainage is surely performed. By using the rear roof panel 2R that is a resin member, there is no risk of rusting, and the spot dents 14a between the roof extension 5 and the rear roof rails 11 are covered by the flooded portion 2R1 of the rear roof panel 2R, which makes it look good. Also improves.

Note that the present invention is not limited to the above-described embodiment, and the sunroof may be any of a tilting roof and an outdoor sliding roof as long as the glass seal part comes off when the sunroof is opened. The material is not limited to glass and may be resin. In any case, it goes without saying that various modifications can be made without departing from the scope of the present invention.
