Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof reinforcing structure for a vehicle with a sunroof, which can improve the rigidity of the roof portion of the vehicle with a sunroof.

[0002]

2. Description of the Related Art In a vehicle with a sunroof, a large hole is formed in a roof panel, and a sunroof device is assembled in the hole, so that the roof panel is required to have sufficient strength. Therefore, conventionally, a reinforcement is arranged around the hole to reinforce the roof panel.

FIG. 10 shows a conventional roof reinforcing structure for an automobile with a sunroof, in which a sunroof device 102 is attached to an opening hole 101 formed in a roof panel 100, and the opening hole 101 is formed by a sunroof glass 103.
Is being opened and closed. 11 to 13 show a roof portion to which the sunroof device is assembled. The roof panel 100 has an opening hole 10 on the upper surface.
1 is formed, and the opening hole 101 is formed by bending the peripheral edge inward.

On both sides of the roof panel 100, a side body panel 106 composed of a side body outer panel 104 and a quarter inner panel (also referred to as a side body inner panel) 105 is provided. The side body panel 106 has a sunroof device. A sunroof mount bracket 107 for assembling 102 is fastened via bolts 108. A sunroof frame 109 for supporting the sunroof device 102 is attached to the sunroof mount bracket 107 by bolts 11.
0 and nut 111 are attached. A sun shade 112 is provided on the indoor side of the sunroof glass 103 of the sunroof device 102.

Reference numeral 113 is a sunroof-type thick plate reinforcement for reinforcing the roof panel 100. As shown in FIG. 14, the lean reinforcement 113 is provided with a downwardly bent portion 114 at the inner edge of the panel whose central portion is opened, and the bent portion 114 is provided inside the opening hole 101 of the roof panel 100. It is joined to the outer peripheral side of the wall surface provided in. A roof lining 115 is provided on the indoor side of the roof panel 100.
According to the above-mentioned conventional technique, in a sunroof-equipped vehicle, the roof panel 100 becomes heavier by the amount of the sunroof device 102. Therefore, it is desirable to use a lightweight reinforcement 113, but in order to secure strength, the plate thickness becomes thick and Causing an increase.

Therefore, as shown in FIGS. 15 to 17, a flange portion 117 is provided by extending the periphery of the lean reinforcement 116, and the front end side and the rear end side of the flange portion 117 are bonded to the back surface of the roof panel 100. Then, the side surface and the side body panel 106 together with the roof panel 1
We have developed a technique for bonding to the back surface of 00 (so-called Mohican part) (Japanese Patent Application No. 5-144456). This makes it possible to reduce the thickness of the lean reinforcement 116 and reduce the weight of the roof panel 100. However, Lean Force 116
If the entire area around the above is widened, the reinforcement 116 becomes large in size, which is not preferable in order to reduce the price of the product. Therefore, a method of extending a portion of the thick reinforcement 13 and joining only the extended portion to the mohican portion of the roof panel 100 can be considered.

On the other hand, in order to standardize the materials such as the side body panel 106 and to reduce the cost, it is required to standardize the vehicle bodies of the sunroof specification vehicle and the normal roof specification vehicle. In the case of a vehicle with a normal roof specification, a strip-like reinforcement 118 is used in this portion, as shown in FIG. 18, instead of the lean reinforcement 113 of the vehicle with a sunroof specification. Generally, the normal roof type lean reinforcement 118 and the sunroof type lean reinforcement 113 have different thicknesses.
It was necessary to make the thickness of No. 8 thicker than necessary to match the thickness of the lean reinforcement 113 of the sunroof type. By the way, thick plate 113
A bracket, which is a separate component, is bolted to the roof panel 100 and the side body panel 10.
Prior art for joining to No. 6 is known (actual fair 6-69
79).

[0008]

However, in this case, since the thickness of the sunroof type lean reinforcement 113 is narrower and the bracket is thicker than the strip-shaped normal roof type lean reinforcement 118, the normal roof is thicker. It was difficult to apply the specification vehicle and the sunroof specification vehicle to the side body panel 106 common to both. Further, the position of the lean reinforcement 113 for an automobile with a sunroof may be displaced or curved due to the tightening condition of the bolts that fasten the bracket, etc., which is not practical.

The present invention can solve the above problems, improve rigidity and reduce weight, and use a side body panel common to both a normal roof type vehicle and a sunroof type vehicle. An object of the present invention is to provide a roof reinforcement structure for an automobile with a sunroof that can be manufactured.

[0010]

In order to solve the above-mentioned problems, the present invention joins the left and right sides of a roof panel having sunroof opening holes to the flanges of a side body panel, and In a roof reinforcing structure of a sunroof-equipped vehicle in which a sunroof-type lean reinforcement for reinforcing the periphery of the sunroof opening hole is arranged, an extension member extending outwardly on both side flange portions of the sunroof-type lean reinforcement. One side of the extension member and the other side of the extension member are joined to the side body panel together with the side part of the roof panel, and the width of the extension member in the front-rear direction of the vehicle is the width of the lean reinforcement of the normal roof specification. It is set to be almost equal to.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 5 show a roof reinforcing structure for an automobile with a sunroof according to the present invention. FIG. 1 shows a vehicle body 1 of an automobile with a sunroof, in which a roof portion 2 of the vehicle body is provided with a sunroof 3. The sectional structure of the roof portion 2 is shown in FIGS. The roof portion 2 is composed of a roof panel 4 and a side body panel 5, and an opening hole 6 for the sunroof 3 is formed on the upper surface of the roof panel 4. A bent portion 7 bent downward is provided at a peripheral portion of the opening hole 6, and a sunroof-type lean reinforcement 8 formed of a thick plate is provided on the back side of the bent portion 7. Has been. This lean force 8 is shown in FIG.
As shown in FIG. 7 and FIG. 7, it is a frame-shaped member having an opening in the center and is provided on the back surface side of the roof panel 4. The lean reinforcement 8 is bent downward on the inner peripheral side to form a bent portion 9, and the bent portion 9 is formed into the bent portion 9.
It is joined to the back surface of the bent portion 7 by welding such as spot welding or adhesion.

Flange portions 10 are provided on both side ends of the lean reinforcement 8, and the flange portions 10 are provided.
On the rear side, an extension member 1 protruding laterally by a predetermined width
One side part 11a of 1 is spot-welded. The other side portion 11b of the extension member 11 is, as shown in FIGS. 4 and 8, a joint flange portion 12a, 13a of the side body outer panel 12 and the side body inner panel 13, which constitute the side body panel 5, and a roof panel. 4 is joined to the lower surface of the drip rail portion 4a of No. 4 by welding to the Mohican portion. In this case, the side body panel 5 side is bent and the other side portion 11b of the extension member 11 is sandwiched and welded. However, as shown in FIG. 9, the roof panel 4 side is bent and the other side of the extension member 11 is bent. You may sandwich and weld the part 11b. Therefore, the diaphragm die of the roof panel 4 can be commonly used for the normal roof specification and the sunroof specification.

Bolts 14 are attached to both side flange portions 10 of the lean reinforcement 8, and a sunroof frame 15 is fastened via the bolts 14. The sunroof frame 15 is fastened and supported by a sunroof mount bracket (not shown) mounted on the side body panel 5. Reference numeral 16 is a sunshade supported by the sunroof frame 15, 17 is a molding provided on the drip rail portion 4a, and 18 is a roof lining provided on the indoor side of the roof panel 4.

2a, 13a and the drip rail portion 4 of the roof panel 4
a Spot welding is performed between the lower surface and the lower surface. Since both sides of the lean reinforcement 8 are thus supported, the rigidity of the roof panel 4 can be improved. Also, the extension member 11
Since the width of the vehicle body in the front-rear direction is set to be substantially equal to the width of the lean reinforcement of the normal roof specification, the side body panel 5 can be commonly used for both the normal roof specification vehicle and the sunroof specification vehicle. further,
Since the thickness of the extension member 11 can be made thinner than that of the lean force 8, the thickness of the normal roof type lean force can be made thinner according to the extension member 11.

The plate thickness of the lean reinforcement 8 is usually molded to about 1.4 mm in order to fix the sunroof unit. However, the normal roof type lean reinforcement can satisfy the function even at 1.0 mm. The thickness of the extension member 11 can be set to 1.0 mm, and the thickness of the normal roof specification reinforcement can be set to 1.0 mm. In this way, the thickness of the normal roof specification reinforcement can be made thinner than before.
