[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body assembling method and a vehicle body structure relating to a connection between an engine compartment skeleton assembly and a body side skeleton assembly.

[0002]

2. Description of the Related Art As a conventional vehicle body assembling method and a vehicle body structure of this kind, there are, for example, those shown in FIGS. A similar structure is disclosed in Japanese Utility Model Application Laid-open No. 63-108869.
There is one such as described in Japanese Patent Publication No. The vehicle body structure shown in FIGS. 5 and 6 has an engine compartment skeleton assembly 1.
And the body side skeleton assembly 2.
The engine compartment skeleton assembly 1 includes a hood ridge 3, a strut tower 4, and a cowl box 5.
And so on.

The hood ridge 3 has a closed cross-sectional structure in which a hood ridge reinforcement 7 is connected to the outer side in the vehicle width direction of a hood ridge panel upper 6 constituting an upper portion of the hood ridge panel. Although not shown, the hood ridge panel has a hood ridge panel lower below the hood ridge panel upper 6. The strut tower 4 is connected to the engine room side at the front and rear intermediate portion of the hood ridge panel, and supports the upper portion of the suspension strut by fastening and coupling. A strut tower brace 8 having one side coupled to the strut tower 4 is provided in the hood ridge 3.

The cowl box 5 is a vehicle body frame member having a closed cross-sectional structure extending in the vehicle width direction below the front window, and is coupled to the rear end of the hood ridge 3. The front lower side of the cowl box 5 and the food ridge panel including the food ridge 3 include:
The dash lower panel 9 is connected.

The engine compartment skeleton assembly 1 includes a front side member, a radiator core support upper, a lower, and the like in addition to the illustration.

[0006] The body side skeleton assembly 2 includes a front pillar 10 which is a skeleton member having a closed cross-sectional structure, and includes an outer panel 11 and an inner panel 12. 13 is a dash side panel. The outer panel 11 is formed by press-forming a single plate as a whole, including, for example, not only the front pillar 10 and the dash side panel 13 but also the side roof rail, the center pillar, the rear quarter, and the side sill. The panel 12 and the like are divided at each part such as the front pillar 10 and the roof side rail, and are joined to the outer panel 11 to have a closed cross-sectional structure.

The lower end of the dash lower panel 9
A floor panel (not shown) is connected to a lower end of the dash side panel 13 and a side sill (not shown).

The method of assembling the vehicle body with the vehicle body structure is as follows. That is, as shown in FIGS. 5 and 6, the engine compartment skeleton assembly 1 is connected to the hood ridge panel upper 6, the strut tower 4, the cowl box 5, the dash lower panel 9, etc., except for the hood ridge reinforcement 7. Next, a floor panel (not shown) is joined to the dash lower panel 9 by spot welding.

The body side frame assembly 2 has a closed cross-sectional structure in which the inner panel 12 and the like are joined to the outer panel 11 by spot welding separately from the engine compartment assembly 1. A strut tower brace 8 is previously joined to the hood ridge reinforcement 7 by spot welding.

Then, the engine compartment skeleton assembly 1 excluding the hood ridge reinforcement 7 is connected to the body side skeleton assembly 2 as shown in FIG. In FIG. 5, the coupling flange portion 15 formed in the range of the arrow B of the body side skeleton assembly 2 is attached to the coupling flange portion 14 of the engine compartment skeleton assembly 1 in the range shown by the arrow A in FIG. The two flange portions 14 and 15 are joined by spot welding.

Then, the connecting flanges 16 and 17 of the hood ridge reinforcement 7 are connected to the connecting flanges 18 and 19 of the hood ridge panel upper 6 by spot welding, and the hood ridge reinforcement 7 is connected to the hood ridge reinforcement 7 by spot welding.
The rear connection flange portions 20 and 21 are brought into contact with a connection surface 21 formed in the range of the arrow C of the body side skeleton assembly 2 and welded. In addition, the body side frame assembly 2 is joined to the side of the floor panel at a lower portion by spot welding or the like.

Thus, the connection between the engine compartment skeleton assembly 1 and the body side skeleton assembly 2 can be completed.

Reference numeral 22 denotes a door hinge mounting surface, and 23 denotes a hood hinge mounting surface.

[0014]

However, in the vehicle body structure and the vehicle body assembling method described above, the connection between the hood ridge reinforcement 7 and the body side frame assembly 2 tends to be unstable, and the strut tower brace is used. 8
Despite the provision, it could not be said that it was enough reinforcement for suspension input. That is, the coupling flange portion 20 at the rear end of the hood ridge reinforcement 7 is provided.
In the part where the front pillar 10 has a closed cross-sectional structure formed by the outer panel 11 and the inner panel 12, the welding sequence is performed by welding to the connecting surface 21. Since arc welding must be performed along the line 20, there is a limit in obtaining stable appearance quality.

On the other hand, if work holes are provided in the outer panel 11 and the inner panel 12 of the front pillar 10, spot welding can be performed even if the front pillar 10 has a closed cross-sectional structure. There is a possibility that a problem may occur in terms of the upper quality, appearance quality, and airtightness of the passenger compartment.

The strut tower brace 8
Is formed by spot welding in advance to the hood ridge reinforcement 7 and spot welding the hood ridge reinforcement 7 to the hood ridge panel upper 6, so that the strut tower 4 and the strut tower brace 8 and the like are connected. The coupling is as shown in FIG. 7 as viewed from the line VII-VII in FIG. That is, the connecting flange portion 24 of the strut tower brace 8 is spot-welded by being overlapped with the hood ridge reinforcement 7, and the connecting flange portion 16 of the hood ridge reinforcement 7 is joined together with the connecting flange portion 18 of the hood ridge panel upper 6. , And a structure in which three pieces are spot-welded to the strut tower 4. Therefore, the strut tower brace 8 is not directly spot-welded to the strut tower 4 but is indirectly connected via the hood ridge reinforce 7, so that the upper and lower struts on the strut tower 4 cannot be welded. The structure was disadvantageous for suspension input.

In order to solve such a problem, before the body side skeleton assembly 2 is made to have a closed sectional structure, the connecting flange portion 20 of the hood ridge reinforcement 7 is connected to the outer panel 1.
1 is joined to the joining surface 21 by spot welding, and then the inner panel 12 and the like are joined to form the body side skeleton assembly 2 including the hood ridge reinforcement 7, and the strut tower brace 8 is a hood ridge reinforcement. A structure and a method for solving the above-mentioned problem by spot-welding to the strut tower 4 and the hood ridge panel upper 6 in three layers from the beginning and connecting the two assemblies 1 and 2 instead of connecting them in advance are considered. Can be

However, in this case, the hood ridge reinforcement 7 is long and cantilevered in front of the body side skeleton assembly 2 before the two assemblies 1 and 2 are joined, and during assembly and transfer, etc. A large stress concentration occurs at the joint of the hood ridge reinforcement 7 to the body side skeleton assembly 2, and the ridge may be deformed.
