Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automobile body structure particularly suitable for application to so-called three-door cars and five-door cars in which a roof panel can be shared.

[Prior Art] Conventionally, 3-door cars and 5-door cars share a roof panel, and the cross-sections of the upper quarter windows of 3-door cars and 5-door cars are shown in FIGS. 3 and 4.
As shown in the figure, the drip channel 2 and the drip channel 3 were constructed in a similar relationship to the roof panel 1. 3 is a sectional view of the 5-door car 4 shown in FIG. 5 taken along the - line, and FIG. 4 is a sectional view of the 3-door car 5 shown in FIG.
FIG. 3 is a cross-sectional view taken along a line. In FIGS. 3 and 4, reference numeral 6 indicates a quarter panel, and 7 indicates a roof side inner panel. Further, in FIG. 3, reference numeral 20 is a molding, and in FIGS. 5 and 6, reference numeral 22 is a front door, and reference numeral 24 is a rear door.

[Problems that the invention attempts to solve] By the way, the quarter window of a 5-door car 4
(See FIG. 3), when the roof panel 1 is shared and the construction is similar to that of the three-door vehicle 5, the quarter panel 6 is attached to the spot welding gun 9 in order to secure the working space for the spot welding gun 9.
This results in a structure that largely misses the point. That is,
A surface 6a recessed toward the indoor side of the quarter panel 6
It is necessary to provide Therefore, in order to hide this area from the outside, the inner surface of the window glass 8a of the quarter window 8 must be coated with ceramics 10 in a vertical direction (as indicated by dimension H in FIG. 3), which is disadvantageous in terms of exterior appearance. It arrived. In addition, in the above structure, the interior trim 11
It also had to be made wider in the vertical direction, and the interior also had the problem of looking unsightly.

The purpose of this invention was made in view of the above-mentioned problems.The purpose of the present invention was to create an automobile body structure that allows the roof panel of a 3-door car and a 5-door car to be shared, without causing any loss in design. is to provide.

[Means for Solving the Problems] The vehicle body structure according to the present invention has a drip channel extending from a predetermined position at the front end to the upper part of the quarter window at the rear of the rear door, and a drip channel extending from the upper part of the quarter window to the rear end side. The structure eliminates the lip channel, and from the upper part of the quarter window to the rear end side, the quarter panel is provided with a protrusion that protrudes upward and outward from the vehicle body, and the end of this protrusion is located inside the vehicle body. A roof panel, a quarter panel, and a roof side inner panel are welded together so as to sandwich the protruding portion, and a quarter window window glass is provided at the bent portion. It is characterized by the fact that the upper end of the

According to the above configuration, the roof panel, the quarter panel, and the roof side inner panel are integrally welded to the protrusion provided on the quarter panel so as to protrude upward and outward from the vehicle body. That is, since the spot welding gun can be welded by sandwiching it from the interior and exterior sides of the automobile using the opening of the quarter window, there is no need to provide an escape for the spot welding gun. For this reason, the number of parts to be subjected to exterior treatment and interior treatment for concealing the relief that occurs in the case of a structure with relief is reduced, so that the appearance of the interior and exterior is improved.

Moreover, since this protrusion protrudes upward and outward from the vehicle body, the interior space of the vehicle is not sacrificed.

Furthermore, the end of the protrusion is bent toward the inside of the vehicle body to provide a bent portion, and the upper end of the quarter window windshield is attached to this bent portion. No need to sacrifice interior space.

In addition, when performing exterior treatment, it is only necessary to apply the exterior material up to the part where the window glass is attached to the bending part, so from this point of view as well, the number of areas to be coated with the exterior material is reduced.
Improves the appearance of the vehicle exterior.

[Example] Hereinafter, details of the present invention will be explained using examples shown in the drawings.

FIG. 1 is a perspective view of essential parts showing an embodiment of an automobile body structure according to the present invention, and FIG.
It is a sectional view taken along a line, and the same parts as in FIG. 3 are given the same reference numerals. As shown in Fig. 1, the roof panel 1 has a structure in which it is welded to the drip channel 13 up to the upper part of the rear door, but the drip channel 13 is eliminated at the upper part of the quarter window, and instead, the drip channel 13 is welded to the quarter panel 14. A protrusion 14a is provided. This protrusion 14a
protrudes upward from the general surface of the quarter panel 14 and toward the outside of the vehicle interior. Further, the end of the protrusion 14a extends parallel to the general surface of the quarter panel 14, and after being bent inward into the vehicle interior, the end of the protrusion 14a extends parallel to the general surface of the quarter panel 14. The bent portion 30 is extended so as to be located in the same plane as the surface.
The structure is such that the protrusion 14a, the roof panel 1, and the roof side inner panel 16 are welded together. At this time, spot welding gun 1
5 uses the opening of the quarter window to connect the welding points of the roof panel 1, the quarter panel 14, and the roof side inner panel 16 to the interior side of the automobile.
It is set so that it is sandwiched from the outside of the room. Also,
The upper end of the window glass 8a of the quarter window 8 is attached to the bent portion 30 formed by bending the end of the protrusion 14a.

Therefore, according to the structure of the present invention, there is no need to set a relief in the quarter panel 14 for the spot welding gun 15, so that the coating is applied to the molding 17, the quarter window 8, and the inner surface of the window glass 8a of the quarter window 8. The position of the ceramics 10 to be applied is limited only by the moldability of the quarter panel 14 and the roof side inner panel 16, and as a result, compared to the conventional structure, the vertical application length of the ceramics 10 can be halved. It became. In addition, the quarter panel 14
Since the spot welding gun 15 does not need to have a large recessed shape, the interior trim 18 does not need to be wide vertically. Therefore, the structure of the present invention has the advantage that both the interior and exterior look better than the conventional structure.

Further, since the protrusion 14a protrudes upward and outward from the vehicle body relative to the general surface of the quarter panel 14, the interior space of the vehicle does not need to be sacrificed.

Furthermore, since the upper end of the window glass 8a of the quarter window 8 is attached to the bent portion 30 formed by bending the end of the protrusion 14a, from this point of view as well, the interior space of the vehicle is not sacrificed. You don't have to.

In addition, when performing exterior treatment, it is only necessary to apply the ceramics 10 up to the attachment area of the upper end of the window glass 8a to the bending part 30, so the area to be applied with the ceramics 10 is reduced from this point of view as well. Improves the appearance of the exterior.

[Effects of the invention] As explained above, according to the automobile body structure according to the invention, not only can the roof panel of a three-door car and a five-door car be shared, but the welding gun can also weld the roof panel from the indoor side and the outdoor side. Since the structure is such that the welded portions of the quarter panel and the roof side inner panel are sandwiched, there is no longer a need to provide the quarter panel with a surface that is concave toward the interior of the vehicle, as was the case in the past. Therefore, the ceramic coated on the inner surface of the quarter window glass does not need to be very long in the vertical direction, and the interior trim does not need to be wide in the vertical direction. Therefore, it is possible to improve the appearance of both the interior and exterior.

Further, since this protrusion is provided on the quarter panel so as to protrude upward and outward from the vehicle body, the interior space of the vehicle does not need to be sacrificed.

Furthermore, the end of the protrusion is bent toward the inside of the vehicle body to provide a bent portion, and the quarter window window glass is attached to this bent portion. There is no need to sacrifice.

In addition, when performing exterior treatment, it is only necessary to apply the exterior material up to the part where the window glass is attached to the bending part, so from this point of view as well, the number of areas to be coated with the exterior material is reduced.
Improves the appearance of the vehicle exterior.
