Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a vehicle body structure, and more particularly to a vehicle window structure applicable to a roof panel of an automobile.

<Prior art> Generally, the structure of a vehicle front window, rear window, quarter window, etc., is such that the periphery of the sheet glass is bonded to the opening edge of the vehicle body with a sealing adhesive, and a weather stop,
A mall is attached, and rubber is attached to the inside of the adhesive in some cases to improve the sealing performance against rainwater. However, since there is a considerable difference in dimensional accuracy between the plate glass and the vehicle body structure made of a steel plate, it is not easy to assemble the mounting positions accurately while maintaining the sealing property. Further, since sufficient rigidity cannot be obtained in the window portion, there is a risk that the adhesion of the sheet glass or the like may occur during the vehicle assembly process and the sealing performance may be impaired.

On the other hand, in recent years, a sunroof structure has been widely used in which a roof panel of an automobile is partially configured with window glass or opened and closed so that sunlight and outside air are taken into the vehicle interior to enhance a feeling of liberation during traveling. There is. However, particularly in the case of a small passenger car, there are problems that the opening area of the sunroof portion is small and the sunroof portion is not housed in the roof panel when opened. In addition, there are so-called T-bar roof structure where the roof panel is partially removable, open body structure that removes the entire roof panel, etc., but noise due to wind noise during running, adjustment of vehicle interior temperature corresponding to external environment, Or there is a problem in response to rainfall.

Therefore, if the entire roof panel is made of a translucent plate material such as glass, a sufficient feeling of liberation can always be obtained and the above problems can be solved. However, since the body of an automobile is generally assembled by spot-welding pressed steel plates, a glass roof panel and a body part made of steel plates are joined together.
Problems such as elimination of the difference in dimensional accuracy between glass and steel plate, assembling and rigidity of the vehicle body will occur. Therefore, it is difficult to apply the conventional window structure as it is to the glass-structured roof panel. Further, if the entire vehicle body has a special structure for a roof panel having a glass structure, the manufacturing cost will be increased, which is not preferable.

<Problems to be Solved by the Invention> Therefore, in view of the above-mentioned problems, the main object of the present invention is to provide a vehicle window structure that enhances the rigidity of the vehicle body, is easy to assemble, and has an excellent sealing property. To do. Another object of the present invention is to provide a vehicle window structure that can be applied to a glass-structured roof panel that can be easily joined to another vehicle body part shared with a normal roof panel structure made of steel sheet. It is in.

<Means for Solving the Problems> According to the present invention, the above object is to provide a vehicle window structure for bonding and holding a translucent plate material to an outer surface of an inner peripheral edge portion of an opening of a vehicle body. A ridge extending along the circumferential direction of the opening is at least partially formed on the outer surface of the opening, and the translucent plate member is joined and held inside the ridge at the inner peripheral edge portion, and A first molding having a lip extending to the outside of the ridge is attached to the outer peripheral edge of the plate material, and the lip is pressed by the second molding attached to the outside of the ridge to the ridge. This is achieved by providing a vehicle window structure characterized in that they are in close contact.

<Operation> In this way, the lip of the first molding mounted on the plate material is wound along the ridge by the second molding mounted on the outside of the ridge, and the lip is closely adhered to enhance the sealing property. it can.

Is a mall 1 attached to the side edge thereof as a first mall
By fixing the lower end of 3b to the upper surface of the inner peripheral edge portion 19 with the double-sided tape 32 and filling the space between the double-sided tape 32 and the groove 20 with the adhesive material 33 having a sealing property, the lower surface 27 of the plate glass is changed to the inner peripheral edge portion. It is joined to the upper surface of 19. The outer side of the ridge 31 is bent downward to form a narrow step portion 34. As shown in FIG. 2, the step portion 34 is formed by bending the side edge of the front frame 15 continuously to the step portion and is formed by bending the side edge of the outer frame member 12 back and forth. A joint portion 22 with a side roof rail extending in the direction is configured. The side roof rail 3 is formed in a box-shaped cross-section having a flange portion 37 by superposing and welding an outer panel 35 and an inner panel 36 at upper and lower side edges, respectively. A stepped portion 34 is superposed on the flange portion 37 to form a concave groove 38 having a dovetail-shaped cross section, and the bottom portion thereof is spot-welded to be integrally joined. Lip 39 of the mall 13b
Extends outwardly beyond the upper end of the protrusion 31, and its tip hangs down into the groove 38. In addition, the inner peripheral edge portion 19
A roof lining trim 41 is attached to the inner end 40 of the ridge, and supports the peripheral end of the roof lining 42.

As shown in FIG. 6, a clip 44 having two protrusions 43 is fixed in place on the bottom of the groove 38. Although not shown in FIG. 4, a molding 45 as a second molding is fitted into the groove 38 over the entire length thereof. In this molding 45, the protrusion 43 is inserted into the inner groove 46 of the retainer integrally provided on the inner side portion thereof, and the respective lips 47 to 50 are elastically engaged with the side wall of the concave groove 38 to prevent the molding from coming off. And then fixed. At this time, the lip 39 of the molding 13b (first molding) is brought into close contact with the wall surface of the groove 38 by the lip 49 of the molding 45 (second molding), so that the rainwater is prevented from entering the molding 13b.

As shown in FIGS. 2 and 5, the rear frame 16 has an upward projecting ridge 51 formed at the rear end of the inner peripheral edge portion 19 and is bent downward to form a hinge mounting portion 52 for the tailgate 5. A stepped portion 53 is provided. Further, the rear frame 16 is formed into a box-shaped cross section by overlapping and welding with the inner panels 55 and 56 at the inner end 54 and the step portion 53, and the tail gate 5 can be opened and closed by a hinge (not shown) attached to the hinge attachment portion 52. To support. The molding 13c attached to the rear edge of the plate glass 11 has a recess 57 having a cross-sectional shape that complements the protrusion 51 on the lower surface thereof. The plate glass 11 is positioned in the front-rear direction by engaging the recess 57 of the molding 13c with the protrusion 51 of the rear frame 17. Further, by filling the space between the groove 20 and the molding 13c with the adhesive 58 having a sealing property, the lower surface 27 of the plate glass 11 is joined to the upper surface of the inner peripheral edge portion 19. Further, a roof lining trim 59 is fixed to the inner end 54 of the rear frame 16 that is overlapped and welded to the panels 55 and 56.

As shown in FIG. 2, the protrusions 51 are provided on the rear frame 16 excluding the central portion and both side portions so that a gap is partially formed between the molding 13c and the inner peripheral edge portion 19. . Accordingly, the moldings 13a and 13b and the outer frame member 1
Rainwater that has entered the inside from between 2 and the double-sided tape 25,
32 and the sealing adhesives 26, 33, and 58 do not enter the vehicle interior by being blocked, and the moldings 13a and 13b and the inner peripheral edge portion 1
9 flows toward the rear frame 16 side along the gap with 9, and is discharged from the gap in the center and both side portions of the rear frame 16. Further, water droplets attached to the lower surface 27 of the plate glass 11 flow outward along the curved surface of the plate glass 11 and are discharged from the drainage channel through the groove 20.

In this way, by using the outer frame member, and by holding the plate glass inside the ridge and overlapping the step portion on the outer side with the flange portion on the vehicle body side and welding, the vehicle body other than the roof panel can be relatively easily manufactured. The entire roof panel can be made into a glass structure at low cost by sharing the parts, and the feeling of liberation during driving is dramatically improved.

Although the roof panel having a glass structure has been described in the above embodiments, the present invention can be applied to a general adhesive window structure such as a front window, a rear window and a quarter window. For example, the window structure according to the present invention may be used to connect a quarter window and an adjacent rear window. In this case, the outer frame member is not always necessary. Further, a groove can be provided along the peripheral edge of the adhesive flange portion of the vehicle body opening, similarly to the groove 20 of the outer frame member described above.

<Effects of the Invention> As described above, according to the present invention, the rigidity of the vehicle body is improved by providing the front and rear ridges on the side frames of the outer frame member. It is possible to prevent adhesion failure and the like. Moreover, high sealing performance can be ensured by winding the lip of the molding of the outer frame member into the groove by another molding and bringing it into close contact with the ridge wall surface. Further, by adjusting the degree of winding of the lip into the concave groove, it is possible to easily absorb the variation due to the difference in dimensional accuracy between the steel plate and the plate glass, and to improve the appearance of the vehicle.
