Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a structure for a roof side rail in an automobile equipped with a door without a sash, which reduces the number of parts, significantly improves assembly workability, and reduces manufacturing costs.

[Prior art and its problems]

In a car using a door without a door as described above,
By coming into direct contact with the door glass, it prevents wind, rain, water, dust, and sound from entering the vehicle interior, and also reduces the impact when opening/closing the door and raising and lowering the door glass, and even protects the door glass while driving. A weather strip is attached to the roof side rail to prevent vibrations. An example of such a roof side rail structure for an automobile is disclosed in Japanese Utility Model Application No. 137711/1983. A cross section of the structure of this roof side rail is shown in FIG. This roof side rail a has a closed cross-sectional structure formed by a roof side rail outer b, a roof side rail inner C, and a retainer d that holds a weather strip e. That is, on the inside in the vehicle width direction, the edges of the outer roof side rail b and the inner roof side rail C are welded, and at the lower end of the roof side rail a, the edges of the inner roof side rail C and the retainer d are welded. The edges are welded, and on the outer side in the vehicle width direction, the edge of the roof side rail outer b and the bottom surface of the retainer d are welded. However, such a conventional structure has the following problems. First, the roof side rail outer b1, the roof side rail inner C, and the retainer d must be made by cutting and press-molding a flat plate using special molds. Therefore, the manufacturing process has become complicated, which has been a factor in increasing the manufacturing cost of the component itself. In addition, in the assembly process of the roof side rail a, the retainer d is welded to the roof side rail outer b, and then the roof side rail inner C is welded to the roof side rail outer b and the retainer d. . In other words, three members were welded at three locations. Therefore, the assembly process becomes complicated due to the large number of parts and the large number of welding points, resulting in an increase in manufacturing costs in the assembly process. The present invention was devised under the above-mentioned circumstances, and it solves the above-mentioned conventional problems, reduces the number of parts, saves labor in the assembly process, and improves assembly workability.
The object of the present invention is to provide a roof side rail structure that significantly reduces manufacturing costs.

[Technical means for solving the problems] In order to solve the above-mentioned problems, the present invention provides a light grooved steel or a hollow grooved steel (
These are hereinafter referred to as groove shaped steel), and a panel member whose both side edges are joined to the outside of both side walls of the groove shaped steel and forms a closed cross-sectional structure in cooperation with the bottom wall of the groove shaped steel. A roof side rail is formed, and the weather strip is held directly on the inner surface of the groove of the groove section of the roof side rail.

[Actions and effects of the present invention]

In the present invention, a roof side rail is formed from a commercially available groove steel and a panel member, and the weather strip is held by the groove steel. Therefore, it is no longer necessary to press-form the retainer for holding the weatherstrip from a flat plate through a special process, as in the past, and manufacturing costs are significantly reduced. Further, in the present invention, the roof side rails are formed of groove shaped steel and panel members. In other words, the two conventional roof side rail outer and roof side rail inner
Instead of the member, a panel member, which is one member, is used. Therefore, since the roof side rail can be constructed from two members, the groove shaped steel and the panel member, the number of members can be reduced compared to the conventional method. Furthermore, since it is sufficient to perform welding at two locations: the side wall of the groove shaped steel and the side edge of the panel member, the number of welding locations can be reduced compared to the conventional method. As a result, assembly workability is significantly improved, and manufacturing costs in the assembly process can be significantly reduced.

[Explanation of Examples]

Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an automobile to which a roof side rail structure according to the present invention is applied, and FIG. 2 is a sectional view of the roof side rail 1. This roof side rail 1 is arranged such that the groove part 3 faces the inner surface of the door opening, and the lip groove section 2 and the side edge 7.7 are welded and joined to the outside of the side wall 5.5 of the lip groove section 2. , and a panel member 6 that cooperates with the bottom wall 4 of the lip groove shaped steel 2 to form a closed cross-sectional structure. Furthermore, the edge 8a of the roof panel 8 is attached to the outer surface of the outer side wall 7 of the panel member 6 by welding. Therefore, compared to the conventional method shown in FIG. 5 in which the roof panel is welded at the drip portion, the number of welding locations and the number of parts can be significantly reduced. The welding marks on the edge 8a of the roof panel 8 are formed by a molding 9 attached to the edge 8a with an adhesive 10 or the like.
covered by. As shown in FIG. 2, by bringing the outer end of this molding 9 into close contact with the lip groove section steel 2, it becomes unnecessary to apply sealant between the roof site rail 1 and the roof panel 8 as in the conventional method. . A protector 11 for sealing a gap with respect to the roof panel 8 is fitted into the inner edge of the molding 9. This mall 9
is made by resin molding, and therefore a drip can easily be integrally formed on the edge of the door glass side as shown by the imaginary line in FIG. Further, the edge of the inner side edge 7 of the panel member 6 extends slightly further downward than the lower end of the side wall 5 of the lip groove shaped steel 2, and the trim T is fitted therein. Further, the base 13 of the weather strip 12 is held in close contact with the bottom 4 of the groove 3 of the lip groove section 2 and the inner surface of the side wall 5. This weather strip 1
The easily deformable head 14 of No. 2 is arranged so that it can be sandwiched between the outer edge of the panel member to which the trim T is attached and the inner surface of the door glass, and is protected against impact when the door glass is raised and lowered and when the door is opened and closed. This cushions the impact of the vehicle and ensures a good seal inside the vehicle. In this example, as shown in FIG. 3, the structure shown in FIG. 2 is continued to a part of the front pillar as it is, thereby forming the front pillar 15. As shown in FIG. 4, in the portion corresponding to the roof front edge of the structural member consisting of the lip groove wI2 and the panel member 6, which extends continuously from the roof side rail to a part of the front pillar, there is an inner panel 16 on both sides of the windshield. The edges are attached by welding in the form of a bridge. In a part of the front pillar, a windshield glass 17 is provided on the outer wall 18 of the panel member 6 facing forward in the vehicle length direction.
is fixed. As this fixing means, for example, after temporarily attaching the inner surface of the peripheral edge of the windshield glass 17 to the outer wall 18 with a double-sided tape 19 having a cushioning property, the edge of the windshield glass 17 is fixed with a clamp 20 in the shape of a cross section. A method of holding and fixing is adopted. A base end 20a of the clamp 20 is fixed to the outer wall 18 by a tapping screw 21. Furthermore, the outer wall 18 or the side edge 7 of the panel member 6
Welding marks between the tapping screw 21 and the lip groove shaped steel 2 appearing on the outer surface of the panel member 6 are located on the outer wall 18 or the side edge 7 of the panel member 6 outward from the clamp 20, and the molding 22 is continuous with the molding 9 in the roof side rail portion. is covered and hidden by being attached with adhesive 10 or the like. Similar to the molding 9 in the roof side rail portion, this molding 22 can have a drip shown by the imaginary line. Moreover, on the inner edge of this molding 22,
A protector 23 for sealing a gap with respect to the clamp 20 is fitted. Furthermore, a trim T that is continuous with the trim in the roof side rail section is attached to the extended edge of the inner side wall end of the panel member 6. Furthermore, in the groove portion 3 of the lip groove shape m2, a weather strip 12 similar to that in the roof side rail portion is provided.
is installed. In this way, by integrating the front pillar 15 and the roof side rail 1, it is possible to reduce the number of parts in the vehicle body, and furthermore, it is possible to significantly improve the workability of assembling the vehicle body, and to reduce manufacturing costs. can be achieved. Furthermore, the front pillar 15 and the roof side rail 1 have no seam as in the past, so it is possible to create a structure with excellent strength, and the vehicle body can be strengthened. Note that the scope of the present invention is of course not limited to the above-mentioned embodiments. In the embodiment, the edge of the side wall portion was bent inward and grooved steel was used, but it goes without saying that the same effects as the present invention can be achieved even if light grooved steel is used. .
