I: Prior Art 3 Background of the Invention The front body structure of an automobile includes side beams arranged along the front and back directions of both sides of the vehicle body, and 10 girder beams arranged along the wide direction of the vehicle body to connect the front ends of the side beams. Each cross section of the side beam and the cross beam is a hollow quadrangular shape, and the bottom surface of the side beam is aligned with the top surface of the cross beam (for example, refer to JP 6-26468). The side beams are formed into a hollow rectangular shape with a cross section, and the upper wall and the inner wall are left at the front end and an opening is provided. The beam is formed by a beam body with an inverted U-shaped cross section and a locking plate (bottom plate) that closes the lower opening of the 15 far beam body. The upper surfaces of the two ends of the beam are close to the rear side of the part that is opened below the side beam and are welded to the inner side wall. A gusset is installed at the joint of the side beam and the beam. The lower edge of the gusset is spot welded to the upper part of the beam, and the outer edge is spot welded to the upper wall with the inner wall of the side marker. The openings remaining below the front of the side beams and the cross beams without being blocked by 20 are closed with a blocking plate. The latching plate has a welded outer edge on the upper edge of the latching wall (front wall), the inner edge of the front side wall, the rear edge of the extension (bottom wall), the inner edge of the bottom wall / knife. The welding flange at the rear edge of the bottom wall is spot-welded to the front side wall of the beam. The other welding flanges are spot-welded to the portions overlapping the side beams. 5 The part of the outer surface of the middle face / force correction is blocked by an extension panel, and the upper edge, the front edge, and the rear edge are folded back toward the wide direction of the car body, and the front edge flange is connected with The front end of the closed side beam is spot welded at the outer edge of the 2 wall, and the flanges at the trailing edge are welded at the 卞, the 刖 end of the side wall and the flange that is bent outward in the width direction of the vehicle body. The flanges are spot welded to the extension panels of each side beam. In the above structure, the cross beam is installed from the lower side of the side beam. The upper end of the outer edge of the gusset 7 is covered by the upper surface of the side wall of the side beam for anonymizing. After welding the side beam and the cross beam, , The gusset must be installed by spot welding or the side beam and the cross beam must be welded after the gusset is installed by spot welding, or the cross beam of the gusset can be installed by spot welding from the front of the side beam, and the side beam and the cross beam must be welded. Sequential assembly. 4) Since the joint between the plate beam and the gusset is far from the openings on the outside of the two ends facing the beam, it is difficult to perform spot welding with the side beam and beam aligned. In addition, the spot welding of the gusset plate in the cross beam must be complicated in the assembly line in the positioning device that aligns the side beam and the cross beam. 0 According to the beam body of the cross beam welded on the side beam, and then the gusset plate is installed, the locking plate is locked. Installed in sequence under the body beam, so that the joint between the cross beam and the gusset can be easily accessed. However, in this assembly step, since the components must be sequentially installed, the manufacturing process cannot be shortened.

The transport bracket 8 extends downward from the lower portion 32. Here, the transport bracket 8 refers to a bracket used for fixing to a hull when a vehicle or the like is transported by a ship or the like. The gusset 4 is installed across the joint between the cross beam 3 and the side beam 2. As shown in FIG. 7, the gusset 4 is opposite to the cross beam 3, and is bent downward from both ends of the upper portion 31 'at the top wall 33 and the front side wall 34 and the rear side wall 35 at the base point 4a and opposite Side beam 2, welded χ flanges at 25 points on the inner side wall. The gusset 4 extends upward beyond the upper end of the inner side wall 25. The headlamp support 5 is spot-welded X in a state where it is inserted between the inner side wall 25 and the gusset 4 and extends above the upper wall 23. In addition, a rib 5a is provided on the upper wall 23, and a flange 5b provided on the leg is spot-welded to the upper wall 23. The front-end upper pole 6 is fixed across the upper ends of the left and right headlight support frames 5. Next, the assembling sequence of the previous body 丨 will be described.

In addition, the headlamp support 5 is spot-welded to the front end portion of the interior 21. The headlamp support 5 and the outer portion 22 may be mounted on the inner portion 21 first. The inner part 21, the outer part 22 and the headlight support 5 of the side sill 2 are combined into a side sill assembly. As shown in Fig. 4, the gusset 4 is mounted on the upper part 3 of the cross beam 3, and the transport bracket 8 is spot-welded X to the bottom wall 36 of the lower part 32. After the gusset 4 and the transport bracket 8 are mounted, the upper portion 31 and the lower portion 32 of the cross member 3 are spot-welded χ. Next, the upper part 31 and the lower part 32 of the cross beam 3, the gusset 4 and the transport bracket 8 are combined to form a 200424079 horizontal standard assembly. The left and right side beam assemblies are arranged at a certain interval, and are lifted down to form a combination beam assembly. As shown in FIG. 5, the X top wall 33 and the lower wall 24 and the overlaps of the gusset 4 and the headlight support 5 and the inner wall 25 are spot-welded, respectively. The front outer wall 7 is spot-welded X in the following order, for example. As shown in FIG. 6, after the rear flange 7a is spot-welded to the front flange 26c provided on the outer side% of the front edge, the upper flange 7b and the upper portion provided on the outer side edge of the upper wall 23 are convex.

As described above, the front vehicle body 1 is configured. Before the side beam 2 and the cross beam 3 are joined, the 15 headlight support 5 is mounted on the side beam 2, and the gusset 4 and the transport bracket 8 are mounted on the cross beam 3. Furthermore, since the gusset 4 extends upward beyond the upper end of the inner side wall 25 of the side beam 2, the combination cross mark 3 can be raised from below the side beam 2. Therefore, in the assembly line, since the side beam assembly can be transported to the front and the cross beam assembly can be aligned from below, the operation of positioning the farming is simple. In addition, since the upper beam 31 and lower beam 32 of the assembling beam 3, the gusset 4, and the transport bracket 8 are installed on the side beam assembly, the assembling line of the side beam 2 can be assembled with another assembly line. Assembly. Therefore, the assembly efficiency is good, and the production cost can be reduced. In addition, the materials of the upper wall 23, the inner wall 25, and the lower wall 24 of the inner part 21 are connected to the front end. Therefore, assuming forward impact and deflection impact, the twist strength to the forward direction is high. In addition, it is assumed that the impact from the wide direction, since the members of the beam 3 are connected to the front outer wall 7 of the side beam 2, the buckling strength is high. 5 For the mounting portion of the cross beam 3, the cross-sectional shape of the front end portion 2a of the side beam 2 is fixed along the front-back direction, so that the length of the front suspension can be easily adjusted. That is, the size of the front body 1 can be easily adjusted for engines of different sizes. The headlight support 5 is attached to the side member 2 as another component,

Since the transport bracket 8 is mounted on the bent portion bent downward from the lower portion 32 toward the inward bend as shown in FIG. 7, the force acting on the transport bracket 8 can be transmitted from the horizontal mark 3 to the lateral mark. 2. In addition, the shape of the delivery technology is symmetrical, which can reduce production costs. 15 The joint of side beam 2 and cross beam 3 is connected to the lower wall 24 and the top wall 33, the end of the cross lapel (front side 34, rear side 35, bottom wall 36) and the front outer side wall 7, upper part 31 and gusset 4, angle Since the stay 4 is joined to many places of the inner side wall 25, since there are many spot welding X points, the joining strength is high. In the present embodiment, although the joining is performed by spot welding, it is also possible to perform tack welding using a YAG laser. The vehicle body structure before the present invention includes side beams, cross beams, and corner slabs. The side beams are arranged along the front-to-rear direction of the vehicle body on both sides of the front of the vehicle, and have a top wall; the inner side wall extending in a vertical direction and connected to the inner side end of the upper wall in the width direction; and connected to the inner side The lower end of the wall extends below the horizontal direction. 12 Top two two, the body is arranged in the wide direction, and it has the second wall joined to the lower wall of the side beam and the front and rear side walls in the front-rear direction. The gusset is connected to the side wall and the top wall of the beam. It extends beyond the upper end of the inner side wall and extends upward to find the structure of the car body. Because the corners can be positioned in advance ^ && • state ' Aligning the crossbeam in the downward direction of the side marker makes the movement of the device simple.
