Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a roof carrier mounting structure for an automobile, and particularly in a structure in which a fixing part for fixing a roof carrier leg directly to the car body roof itself is formed. The present invention relates to an automobile roof carrier mounting structure that improves the assembling formability of the roof and increases the strength of the mounting portions of the roof carrier legs.

<<Prior art>> In recent years, in order to reduce the air resistance coefficient of the car body, attempts have been made to make the car body a flat surface. A structure called .

This Mohican roof has roof side rails 2 disposed on both sides of the vehicle body roof 1, which form the outer shell of the vehicle body roof 1 along the longitudinal direction of the vehicle body and constitute side members as structural members.
A main roof panel 3 is disposed in the center of the vehicle body by spanning between these roof side rails 2, and the both side ends 3a of this main roof panel 3 and the inner end 2a of the roof side rail 2 in the vehicle width direction are connected to each other. Weather strips are provided at both left and right ends of the vehicle body roof 1 to protrude further outward in the vehicle width direction from the roof side rails 2 to remove rainwater, etc. It seems like there is no such thing.

Therefore, with such a mohawk roof, it is not possible to removably attach and fix the legs 4a of the roof carrier 4 using a weather strip. Forming the fixing part 5 of the leg part 4a,
The leg portion 4a was directly attached to this in a removable manner.

That is, as shown in FIG. 7, the inner end 2a of the roof side rail 2 and the side end 3a of the main roof panel 3
The joint part 6 with the roof carrier 4 is recessed along the front-rear direction of the vehicle body to form a long groove 7, and the leg part 4a of the roof carrier 4 is placed on this long groove 7. An insertion hole 9 for a bolt 8 passing through the joint 6 in alignment with the mounting position of the leg 4a.
At the same time, a nut 10 is welded and fixed to the lower end of this insertion hole 9 to form a fixing part 5, and when the roof carrier 4 is installed, the leg part 4a is fixed.
is directly fastened and fixed onto the vehicle roof 1 with bolts 8.

<<Problems to be Solved by the Invention>> By the way, the roof side rail 2 is constructed as a structural member (side member) of the vehicle body, and the roof side outer panel 11 and the roof side inner panel 12 are arranged above and below. Both end portions 11a, 11b, 12a, and 12b are overlapped and joined to form a hollow shape.

Therefore, at the joint 6 between the roof side rail 2 and the main roof panel 3, the side end 11a of the roof side outer panel 11 is placed on the side end 12a of the roof side inner panel 12, and the main roof panel is placed on the side end 11a of the roof side outer panel 11. The side edges 3a of the panels 3 are overlapped, and the panels 3, 11, 12 of these three members
are welded together at the same time when the vehicle body roof 1 is formed.

On the other hand, the fixing part 5 provided in the long groove 7 of the joint part 6
is not formed by post-processing after the assembly and molding of the vehicle roof 1, but each panel 3 of the three members,
Insertion holes 9 for bolts 8 are formed in each of roof side inner panels 11 and 12, and
A nut 10 is welded to the lower end of the insertion hole 9, and when assembling and forming the vehicle body roof 1, the positions of the insertion hole 9 and the nut 10 of each panel 3, 11, 12 are aligned, and the panel of these three members is assembled. 3,11,
12 are simultaneously welded and joined to form the fixing part 5 of the leg part 4a of the roof carrier 4.

For this reason, the positioning precision control of the three-member panels 3, 11, and 12 during assembly and molding of the vehicle body roof 1 becomes strict, and as a result, the assembly and moldability of the vehicle body roof 1 becomes difficult, reducing productivity. There was a problem.

In addition, when roof carrier 4 is installed,
The load acts concentratedly on each fixed part 5 of the long groove 7 from the leg part 4a, and there is a risk of distortion around the fixed part 5, which raises concerns about the strength of the vehicle roof 1. Ta.

Incidentally, in the "roof carrier device for automobiles" disclosed in Japanese Utility Model Application Publication No. 59-39245, the present applicant provided a carrier base member fixed to the long groove over substantially the entire length thereof, and installed the roof carrier on this carrier base member. A method in which the legs are fixed has been proposed, but although this proposal can provide reinforcement in terms of strength, it requires a long carrier base member as a reinforcing material, and it also has problems in assembling and forming the vehicle roof. However, the above-mentioned problems remain, and there is room for improvement.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a roof carrier mounting structure for an automobile in which the legs of the roof carrier are removably fixed directly to the vehicle roof. An object of the present invention is to provide a roof carrier mounting structure for an automobile, which can improve productivity by reducing positioning accuracy during assembly and molding, and improve the strength of the mounting fixing part on both the carrier leg side and the vehicle roof side. .

Roof side rails are arranged along the longitudinal direction on both sides of the vehicle body, and a main roof panel is provided in the center of the vehicle body by spanning between these roof side rails. In a roof carrier mounting structure for removably mounting a roof carrier on the roof of an automobile, which is formed by joining the roof side rail to the upper end of the roof side rail, Vertical walls extending in the vehicle height direction are formed by raising the main roof panel on both sides thereof, and the upper end of either the roof side inner panel or the roof side outer panel is attached to the inner surface of the vertical wall. At the same time, a fixing part is formed in the overlapping part of the vertical wall and the extension part to penetrate through the overlapping part and removably fasten and fix the leg part of the roof carrier. A seating part is formed on the leg part to be seated at the joint between the roof side rail and the main roof panel and to be seated on the vertical wall, and the seating part is fastened to the fixed part by a fastening member. Features.

<<Function>> In the automobile roof carrier mounting structure configured as described above, the leg portion of the roof carrier has a seating portion formed thereon that is seated at the joint between the roof side rail and the main roof panel, and Since it is seated on a wall, the load is distributed over a wide seating area and transmitted to the vehicle body. In addition, the upper end of either the roof side inner panel or the roof side outer panel is extended and reinforced by overlapping and welding on the inner surface of the vertical wall of the main roof panel. Since a fixing part is provided to fasten and fix the seating part to the fixing part by means of a fastening member passing through the overlapping part, the mounting rigidity on both the leg side and the vehicle roof side is significantly improved.

Furthermore, when assembling and molding the car body roof, it is necessary to consider the alignment of the above-mentioned fixing parts that have been formed in advance on the main roof panel and the roof side inner panel (or outer panel). Since the positioning of two panels is required compared to the positioning of two panels, the accuracy of the joint positioning of each panel during assembly and molding of the car body roof can be relaxed, and as a result, productivity can be improved. become.
