Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile sunroof drain hose wiring structure.

[0002]

In the case of a sunroof type automobile, for example, Japanese Unexamined Patent Publication No. 4-78773 and Japanese Unexamined Patent Publication No.
As disclosed in JP-A-81324, a through hole is formed in a side wall of a corner portion on the roof side of a brace that is formed into a three-forked shape having a substantially hat-shaped cross section that constitutes an inner panel of a roof frame member having a closed cross section. Then, the drain hose of the sunroof unit (hereinafter referred to as the sunroof drain hose) is inserted into this through hole to route the sunroof drain hose within the closed cross section of the roof frame member. Since it has a relatively large diameter so as not to bend and cause clogging, in order to insert this large diameter sunroof drain hose into the side wall of the brace, the area of the through hole forming portion of the side wall must be increased. It is necessary to secure the formation area of the large-diameter through hole.

Usually, the top wall portion of the inner panel of the roof frame member having a substantially hat-shaped cross section is, as is well known, arranged to be inclined toward the outside of the vehicle in order to expand the living space around the head of the occupant. The side wall on the roof side of the inner panel is arranged substantially vertically, and the top wall portion of the brace and the side wall on the roof side are also arranged in the same manner. Therefore, in order to secure the through hole area as described above, There is no choice but to inversely form the hole forming portion to expand the substantially vertical side wall surface downward, and this inverse forming tends to cause the inclination of the top wall portion to protrude toward the passenger compartment.

On the other hand, the passenger compartment side of the roof panel is decorated by being covered with a roof trim over the portion where the roof frame member around the roof is disposed. The portion of the roof trim peripheral side portion corresponding to the brace is Since the appearance is impaired when the bulging portion is formed corresponding to the inversely shaped portion of the brace, the peripheral side portion of the roof trim is angled so as not to interfere with the inversely shaped portion of the brace as a whole.
That is, it is necessary to increase the degree of collapse to the passenger compartment side and perform the inclination molding.

As a result, when a vehicle body having such a roof frame structure is commonly used as a standard roof specification, the degree of collapse of the peripheral side of the roof trim into the passenger compartment is large, so that it is not a sunroof specification. This causes a problem that the living space around the head of the occupant cannot have sufficient space.

Therefore, according to the present invention, when the vehicle body having the roof frame structure of the sunroof type is used for the standard roof type, the living space around the head of the occupant can be expanded, and the habitability is impaired. It is intended to provide a sunroof drain hose wiring structure for an automobile, which can be commonly used for both the sunroof specification and the standard roof specification.

[0007]

According to a first aspect of the present invention, a roof frame member having a closed cross section is formed by an outer panel and an inner panel having a substantially hat-shaped cross section, and a through hole is provided in the inner panel of the roof frame member. Te, in the structure as by inserting a sunroof drain hose into the through-hole is routed in a closed section of the roof frame member, the outer panel and in
A flat section that divides the closed cross-section between the outer panel and the passenger compartment
A plate-shaped reinforcing plate is provided, the through hole is formed in the top wall portion of the inner panel having a substantially hat-shaped cross section, and the reinforcing plate, and the periphery of the through hole forming portion of the reinforcing plate is formed.
It is characterized in that the bead portion is formed by embossing .

According to a second aspect of the present invention, the inner panel according to the first aspect is formed into three crotch shapes connected to the pillar inner, the roof rail, and the roof side rail inner, and the through holes are formed in the three crotch shapes. It is characterized in that it is formed on the top wall portion in the center of the branch portion of the crotch.

[0009]

According to the first aspect of the invention, since the through hole for inserting the sunroof drain hose is formed in the top wall portion of the inner panel of the roof frame member, the top wall portion is originally a member. Since it is formed in a wide area to ensure rigidity, it is possible to secure a sufficient through hole area for inserting the sunroof drain hose, and therefore, to secure the through hole forming area of the inner panel at the through hole forming portion. Since it is not necessary to form the modified cross section, the cross section can be formed into a constant cross section, and the moldability of the inner panel can be improved.

When the vehicle is used in a vehicle with a standard roof, the inner panel has a constant cross-sectional shape, so that the peripheral side portion of the roof trim can be disposed close to the inner panel as a whole along the top wall portion of the inner panel. , It is possible to expand the living space around the head of the occupant.

According to the second aspect, in addition to the effect of the first aspect, the through-hole is formed in the wide-area top wall portion in the center of the branch portion of the three-forked inner panel. Therefore,
The through hole can be formed easily and advantageously in terms of strength.

1 to 3 show a portion of the front roof corner portion C where the sunroof drain hose 4 is arranged so as to penetrate therethrough. The front pillar 5 is formed by abutting a pillar outer 6 and a pillar inner 7 formed in a substantially hat-shaped cross section. And has a closed cross section.

At the upper end of the pillar outer 6, a front roof rail portion 6a and a roof side rail portion 6b are extended to form three crotch shapes, while at the upper end of the pillar inner 7, the roof side rail portion of the pillar outer 6 is formed. A reinforcing plate 7a extending along 6b is extended in a flat plate shape, and the front roof rail portion 6a and the roof side rail portion 6 are provided.
b, the reinforcing plate 7a constitute a roof frame member 8 together with braces, front roof rails (not shown), and roof side rails (not shown). Therefore, in the front roof corner portion C, the upper end of the pillar outer 6 is the outer panel of the roof frame member 8. Are configured.

Reference numeral 9 denotes a brace having a substantially hat-shaped cross section which constitutes an inner panel of the roof frame member 8 at a front roof corner portion C, and the brace 9 is a substantially hat-shaped not shown extending in the width direction of the roof vehicle. A roof rail connecting portion 10 which is fitted and joined to a front roof rail having a cross section, and a roof side rail which is fitted and joined to a roof side rail inner having a substantially hat-shaped cross section of a roof side rail (not shown) extending in the front-rear direction of the roof. The connecting portion 11 and the pillar connecting portion 12 that is fitted and joined to the upper end portion of the pillar inner 7 are formed into three crotch shapes.

Roof side rail portion 6 of the pillar outer 6
b is fitted and joined to the roof side rail outer having a substantially hat-shaped cross section of the roof side rail (not shown),
The reinforcing plate 7a of the pillar inner 7 is abutted and joined to the roof side rail connection portion 11 of the brace 9 by abutting, and the roof rail portion 6a is abutted and joined to the roof rail connection portion 10 of the brace 9 by abutting. In the roof corner portion C, a reinforcing plate 7a is formed inside to form a closed cross section as a reinforcing beam.

A top wall portion 9a of the brace 9 having a substantially hat-shaped cross section.
Is designed to expand the living space around the occupant's head by slanting toward the outside of the vehicle together with the top wall portions of the substantially hat-shaped cross section of the front roof rail and the roof side rail inner described above. The side wall 9b of is arranged substantially vertically.

Then, a through hole 13 is formed in the top wall 9a at the center of the three-branch branch of the brace 9, and the sunroof drain hose 4 is inserted into this through hole 13 to close the roof frame member 8. The cables are arranged in the cross section.

In this embodiment, since the reinforcing plate 7a at the upper end portion of the pillar inner 7 is present in the closed cross section of the roof frame member 8, the through hole 1 is also formed in the reinforcing plate 7a.
3, a through hole 14 is formed at a position corresponding to 3, and the sunroof drain hose 4 is inserted into the through hole 14 and once passed through a portion of the closed cross section that is partitioned to the outside of the vehicle, and the front pillar 5
It is inserted and routed within the closed cross section.

Since the reinforcing plate 7a is flat, the bead portion 14a is formed by embossing around the portion where the through hole 14 is formed, and the surface rigidity of the reinforcing plate 7a is secured.

As described above, according to the structure of this embodiment, the through-hole 13 is formed in the top wall portion 9a of the brace 9 which constitutes the inner panel of the roof frame member 8 in the substantially hat-shaped cross section, and the sunroof drain hose is formed. Since 4 is inserted into the through hole 13 and arranged in the closed cross section of the roof frame member 8, the top wall portion 9a of the brace 9 is originally formed to have a wide area to secure the member rigidity. Therefore, it is possible to secure a sufficient through hole area for inserting the sunroof drain hose 4, and therefore, the brace 9 is inversely formed at the through hole forming portion as shown by the chain line in FIG.
Different from the conventional structure in which the through hole 13a is formed in the side wall 9b, the brace 9 does not have to have an irregular cross section and can have a constant cross-sectional shape. Can be improved.

In particular, in this embodiment, since the through hole 13 is formed in the top wall 9a at the center of the three-branch branch where the large area of the brace 9 can be obtained, the through hole 13 can be easily and easily formed. It can be advantageously formed in terms of strength.

Further, as described above, the top wall portion 9 of the brace 9 is

In order to avoid interference with the sunroof drain hose 4, it is necessary to form a with an angle of inclination that increases the degree of collapse to the passenger compartment side. Since the wall portion 9a projects toward the passenger compartment, the peripheral side portion 15 of the roof trim 15
Since a is formed to have an inclination angle along the top wall portion 9a protruding toward the vehicle interior side indicated by the chain line, the roof trim 15
The inclination angle of the peripheral side portion 15a may be the same as the conventional one and does not particularly narrow the living space around the head of the occupant.

Further, since the sunroof drain hose 4 is routed through the top wall portion 9a of the brace 9, the position where the sunroof drain hose 4 is slightly displaced downwards,
Since the space between the side wall 9b on the roof side and the sunroof drain hose 4 is widened, the harness 16 of the roof electric component (not shown) can be wired in that portion, and the space can be effectively used.

On the other hand, when a vehicle body having such a roof frame structure is used in a vehicle with a standard roof, as described above, the brace 9 has a constant sectional shape without an inverse portion, as shown in FIG. As described above, the peripheral side portion 15a of the roof trim 15 can be risen according to the arrangement inclination angle of the top wall portion 9a to be inclined, and can be arranged closely along the top wall portion 9a. The surrounding living space can be expanded.
