[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for reinforcing a vehicle body having a sunroof unit mounting portion in a vehicle having a sunroof.

[0002]

2. Description of the Related Art FIG. 6 is an explanatory view showing a vehicle body structure of a conventional sunroof mounting portion, and an opening hole 4 for mounting a sunroof is formed in a roof panel 2 of a vehicle 1. FIG. A rigid rigid rail 6 having a closed cross section is provided at the joint between the side of the vehicle body and the side edge of the roof panel 2, and the joint between the front edge of the roof panel 2 and the windshield 10 is provided at the joint. A highly rigid roof front rail 8 having a closed section structure is provided. The periphery of the sunroof mounting opening 4 of the sunroof 2 is reinforced by a reinforcement (reinforcement member) 12, and the sunroof unit 20 is tightened to the reinforcement 12 by bolts 14 and nuts 16.
The sunroof unit 20 includes a frame 22 and a lid 26.
The lid 26 covers the sunroof opening hole 4 so that it can be opened and closed. 6 shows the relationship between the side panel 22A of the frame 22 of the sunroof unit, the roof panel 2 including the cantilever 6, and the reinforcement 12, and the roro section shows the front portion 22B of the frame 22 and the roof front. The relationship between the roof panel 2 including the rails 8 and the reinforcement 12 is shown.

[0003]

In recent years, the opening area of the sunroof has been increased, and there has been a demand for an improvement in the strength of the roof panel in order to prevent deformation of the roof panel during mounting work of the sunroof unit. Cantrail 6
And the roof front rail 8 have a closed cross-section structure, high rigidity, and the reinforce 22 itself has sufficient rigidity, but the roof panel 2 connecting both has a single-sheet structure,
In order to improve the rigidity, it is necessary to increase the thickness, which leads to an increase in the weight of the vehicle body. For example, Japanese Unexamined Utility Model Publication No. 61-146422 discloses a structure in which when a frame of a sunroof unit is fixed to a vehicle body, a reinforcement integrated with the frame is extended and attached to a side rail. In the structure described in this publication, the rigidity around the opening is secured after the frame of the sunroof unit is attached to the sunroof opening, but the rigidity of the roof panel around the opening before the frame is attached is the same as the conventional one. There is still a problem that the roof panel is deformed when the sunroof unit is attached. Also, Japanese Utility Model Application No. 62-8187
Microfile No. 7 (Japanese Utility Model No. 63-189815)
In order to improve the mounting accuracy of the sunroof unit,
And an extension on the rain force,
A linked configuration is disclosed. In this mounting structure
Large sunroof unit and large opening hole area
The sunroof unit weighs the sunroof unit.
Unable to support, mounting deformation around the hole, roof panel
There is a fear that the inconvenience of water leakage in the cabin may occur.
Was. Therefore, the present invention proposes a vehicle body reinforcement structure that solves the above-mentioned conventional problems.

[0004]

According to the sunroof unit mounting structure of the present invention, the sunroof unit is fixed via a reinforcing member which covers the inside of the periphery of a sunroof unit mounting opening formed in the roof. To form a closed cross section between the leading edge member is a roof panel of the reinforcing member, the reinforcing
A sealing plate is provided between the side edge of the member and the roof panel.
The side edge of the reinforcing member forms a closed section with the sealing plate.
You. In addition, the front edge (edge corresponding to the roof front rail) and the side edge (edge corresponding to the cant rail) have a plurality of projections, and the projection of the front edge is arranged at the front of the roof panel. It is directly connected to the roof front rail provided, and the protruding portion of the side edge portion is directly connected to the cantilever provided on the side of the roof panel.

[0005]

Since the three sides of the reinforcing member are directly connected to the roof front rail having a closed cross-sectional structure and the cant rail,
The mounting rigidity of the reinforcing member is improved. Also, the side edge of the reinforcing member
Since the sealing plate is arranged between the part and the roof panel ,
The rigidity around the sunroof mounting opening in the roof panel is also improved.

[0006]

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a sectional view taken along line a--a in FIG. 1, FIG. 3 is a sectional view taken along line A--A in FIG.
1 is a sectional view taken along line bb of FIG. 1, and FIG. 5 is a sectional view taken along line BB of FIG. An opening hole 4 for a sunroof is provided in a roof panel 2 of the vehicle body 1. A roof front rail 8 is formed between the roof panel 2 and the front windshield 10, and a cant rail 6 is provided between the roof panel and the side glass 3. The roof front rail 8 and the roof panel 2 form a closed cross section and have high rigidity. The stay of the interior mirror 80 is attached to the inside of the roof front rail 8 via a head lining 72 .

[0007] The cantilever 6 includes an outer panel 61.
And the inner panel 62 form a closed cross section and have high rigidity. A reinforcing member 40 is fixed around the sunroof mounting opening 4 provided in the roof panel 2. The reinforcing member 40 has a quadrangular frame-like planar shape that covers the periphery of the opening hole 4. A plurality of protruding portions 43 are provided on the front edge portion 42 of the reinforcing member 40, as indicated by reference numeral M in FIG. A plurality of protrusions 46 are also provided on the side edge 45 of the reinforcing member 40 as indicated by reference numeral N. The front edge 42 of the reinforcing member 40 and the roof front rail 8 are connected via the roof panel 2, while the front edge protrusion 43 is directly connected to the roof front rail 8. With this structure, the joint rigidity between the reinforcing member 40 and the roof front rail 8 is improved.

Similarly, the side edge 45 of the reinforcing member 40 and the rail 6 are connected via the roof panel 2, while the side edge projection 46 is directly connected to the rail 6. With this structure, the coupling rigidity between the reinforcing member 40 and the cantilever 6 is improved. Further, a sealing plate 70 is provided between the side edge 45 of the reinforcing member 40 and the roof panel 2.
With the double structure and the side edge 45 having a closed cross-sectional structure, the rigidity of the reinforcing member 40 and the rigidity of the entire roof panel 2 around the sunroof mounting opening 4 are improved. The sunroof unit 50 is fixed to the reinforcing member 40 by a fastener 58 such as a bolt and a nut. Sunroof unit 50 includes a frame 52, a guide rail 55 mounted on the frame 52 has a lid 54 which is guided by the frame 5 2, the lid is openable and closable operation.

[0009]

According to the present invention, as described above, the reinforcing member which reinforces the periphery of the opening of the roof having the opening for mounting the sunroof has a closed sectional structure, so that the reinforcing member has high rigidity. And, while providing a plurality of protrusions at the front edge of the reinforcing member and directly connecting to the roof front rail,
A plurality of protrusions are also provided on the side edges of the reinforcing member and are directly connected to the cantilever, so that three sides of the reinforcing member have a closed cross section.
Roof rails and cantilever rails
The connection rigidity improves the mounting rigidity of the reinforcing member.
You. In addition, there is a tight seal between the side edge of the reinforcing member and the roof panel.
Since a sealing plate is provided, the sun roof
The rigidity around the attachment opening is also improved. Therefore, even before the sunroof unit is mounted, the rigidity of the roof around the mounting hole is ensured, and the roof is not deformed when the sunroof unit is mounted, and the roof is prevented from being deformed by a load such as snow. In addition, since the rigidity is improved, noise due to roof flapping and vibration during traveling is also prevented. In addition, even when the vehicle rolls over, the strength of the roof is high, and damage can be reduced.
