Description

[Detailed description of the invention] Industrial applications The present invention relates to an automobile roof structure.

Prior Art Some automobiles have an opening partially formed in the roof panel, as shown in page 69 of the June issue of Motor Fan published by Sanei Shobo Co., Ltd. on June 1, 1985. It is known that a lighting glass is attached to this opening to expand the lighting inside the vehicle interior.

Problems to be Solved by the Invention In order to increase the amount of daylight inside the vehicle interior, it is possible to make the roof panel almost entirely transparent with light-emitting glass, but this does not allow for slight twisting of the vehicle body while driving. Therefore, as mentioned above, it is necessary to partially provide an opening in the roof panel and install lighting glass in this opening. It is not always possible to expect a significant increase in daylighting. Furthermore, if the lighting glass is attached to an opening partially formed in the roof panel, the roof panel will be directly hit by rain or car wash water, so the reliability of the waterproofing around the area where the lighting glass is installed is unreliable. It has been pointed out.

SUMMARY OF THE INVENTION Therefore, the present invention provides a roof structure for an automobile that can significantly improve lighting inside the vehicle interior without impairing the strength of the vehicle body, and can also improve sealing performance.

Measures to solve the problem: The opening surrounded by roof rails that form the framework on both sides of the vehicle roof is subdivided into multiple openings using multiple roof bows that straddle the opposing roof rails. At the same time, a glass fixing portion is formed at the periphery of each opening with a step at least equivalent to the thickness of the daylighting glass, and the peripheral edge of the daylighting glass is fixed onto the glass fixing portion, and a roof made of a transparent resin material is formed. A panel is fixed to a roof rail and a roof bow, and the roof panel covers lighting glass at intervals in the vertical direction.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In Figures 1 to 5, reference numeral 1 indicates a roof rail that constitutes a frame on both sides of the vehicle body roof by a front roof rail 2, a rear roof rail 3, and side roof rails 4 on both sides, and an opening surrounded by the roof rail. It is subdivided into a plurality of openings 7 by roof bows 5, 6 joined across the front roof rail 2, rear roof rail 3, and side roof rails 4, 4 on both sides (one not shown). The periphery of each opening 7 surrounded by the roof rail 1 and the roof bows 5 and 6 has a step at least equivalent to the thickness of the daylighting glass 8, and in this embodiment, the step is larger than the thickness of the daylighting glass 8. A flange portion 7a is formed as a glass fixing portion, and the peripheral edge of the daylighting glass 8 is fixed onto the flange portion 7a with an adhesive 9 via a dam rubber 10 which also serves as a spacer. 11 is a roof panel made of transparent resin material,
Its peripheral portion is fixed to the upper surface of the roof rail 1 with an adhesive 9. In addition, this roof panel 11
Even if it is in the part corresponding to roof bows 5 and 6,
The roof panel 11 is fixed to the upper surfaces of the roof bows 5 and 6 with an adhesive 9, and covers and protects the above-mentioned lighting glass 8 at intervals in the vertical direction. The roof panel 11 is made of polycarbonate, for example, and is surface-treated with a silicone-based surface hardening agent. The front edge flange 2a of the front roof rail 2 extends substantially on the upper surface of the front roof rail 2, and on the front edge flange 2a, a dam rubber 10 which also serves as a spacer is attached to the upper edge of the front windshield 12. It is fixed with adhesive 9 via. Trailing edge flange 3a of rear roof rail 3
The upper edge of the rear window glass 13 is also fixed to the rear edge flange 3a with an adhesive 9 via a dumb rubber 10 which also serves as a spacer. There is.
Further, between the front and rear edge ends of the roof panel 11 and the upper edge ends of the front windshield 12 and the rear window glass 13, there are a top surface of the front roof rail 2 and a rear roof rail 3, respectively.
A spacer rubber 14 having a sealing function and adhesively fixed to the upper surface is interposed to avoid mutual interference and to provide a sense of continuity between the roof panel 11, the front windshield 12, and the rear windshield 13. . In addition, the ends of both side edges of the roof panel 11 are covered with spacer bars 14 that are adhesively fixed to the upper surface of the side roof rail 4 and have a sealing function to avoid interference with the upper edge of the door sash 16 when the door is closed. Moreover, a sense of continuity between the roof panel 11 and the door sash 16 is provided. 15 in the diagram is roof rail 1
17 and 18 are door weather strips, and 19 is a door glass.

According to the structure of the above embodiment, the lighting glass 8 is divided and arranged for each opening 7 formed by the roof rail 1 and the roof bows 5 and 6, and is made of a transparent resin material with high elasticity as a whole. Since the roof panels 11 are covered with roof panels 11 spaced apart in the vertical direction, the lighting inside the vehicle can be greatly expanded.
The material does not act as a bracing material, and does not allow the vehicle body to twist, thereby reducing the strength of the vehicle body. In addition, since the roof panel 11 is entirely covered with a transparent resin material, there is no problem with the sealing properties around the lighting glass 8. 8 can be protected, so damage can be prevented even if the lighting glass 8 is formed of a light control glass that can change the amount of light transmission depending on the amount of sunlight, for example. Furthermore, since the roof has a double structure with the roof panel 11 and the lighting glass 8, it has excellent heat insulation and sound insulation effects, and together with the expansion of lighting, the atmosphere inside the vehicle can be further improved. In particular, if the lighting glass 8 is made of light control glass, the amount of lighting can be freely changed and the quality can be further improved.

In the above embodiment, the roof panel 11, the front windshield 12, and the rear windshield 1 are
3 and the door sash 16 are aligned and continuous substantially flush with each other to form a so-called flat surface ace, which improves aerodynamic characteristics and appearance. However, the present invention is not limited thereto. Of course.

Effects of the Invention As described above, according to the present invention, the daylighting glass is divided and arranged for each opening surrounded by the roof rail and the roof bow, and the daylighting glass is arranged with a roof panel made of a transparent resin material having excellent elasticity. Since the entire body is covered at intervals in the vertical direction, it can tolerate the twisting of the car body while driving, greatly expanding the lighting inside the car without compromising the car body strength, and also preventing water from flowing around the lighting glass. It can completely prevent leakage. Moreover, the roof panel can protect the lighting glass, and the roof panel and lighting glass can form a double structure, which has a great practical effect in that it can improve heat insulation and sound insulation effects. have an effect.
