By the way, the shipping bracket is generally formed by processing a sheet metal in order to reduce the weight and cost. In the case of a sheet metal shipping bracket, since the rigidity against an input load in the plate thickness direction is low, it can be reinforced by bending the periphery of the hook hole where stress is concentrated and the peripheral edge portion in a flange shape to increase the rigidity.

Therefore, in the process of devising the present invention, the present inventor has developed a sheet metal shipping bracket 110 having a reinforcing structure as shown in FIG. 6 and attached to a vehicle body as shown in FIG. 7. As shown in FIG. 6, the shipping bracket 110 is configured by combining panel members 110A and 110B made of sheet metal.

It has a hooking portion 112 formed on (the lower end side at the time of mounting the vehicle body) and having a hook hole 114 for locking the fixing hook, and an intermediate portion 113 extending between the vehicle body mounting portion 111 and the hooking portion 112. ing. The vehicle body mounting portion 111 is formed in a flat plate shape so that it can be joined to the vehicle body frame 1 over a wide area.

Hereinafter, the panel members 110A will be described with reference to the peripheral portions of the panel members 110A and 110B, which are bent diagonally toward the front side in FIG. 6 to form the flange portion 115, whereby the rigidity is increased. Further, in FIG. 6, a bead portion 116 projecting diagonally toward the front side is formed so as to surround the outer circumference of the hook hole 114. Among the panel members 110A and 110B, a bead portion 117 projecting diagonally toward the front side is also formed in the flat intermediate portion 113 which is widespread in a wide area in FIG. 6, and the rigidity is enhanced. The two bead portions 116 and 117 are formed independently of each other.

The panel members 10A and 10B have a vehicle body mounting portion 11 joined to the vehicle body frame 2 on one end side which is upward when the panel members 10A and 10B are attached to the vehicle body 1, and are fixed to the other end side which is downward when the panel members 10A and 10B are attached to the vehicle body 1. It has a hooking portion 12 formed with a hook hole 14 for locking the hook 19 (see FIG. 5). An intermediate portion 13 that separates the two 11 and 12 is provided between the vehicle body mounting portion 11 and the hooking portion 12, and when the shipping bracket 10 is attached to the vehicle body 1, the hooking portion 12 is attached to the vehicle body frame 2 (see FIG. 2). It is designed to take a position that protrudes downward.

The panel members 10A and 10B are formed with bead portions 15 that continuously extend from the periphery of the hook hole 14 of the hooking portion 12 to the vehicle body mounting portion 11 via the intermediate portion 13. Although the details will be described later, the panel members 10A and 10B have a main surface portion 10 m as a reference surface thereof, and the bead portion 15 is formed so as to project to one surface side (outer surface side) of the main surface portion 10 m.

In the case of the present embodiment, the shipping bracket 10 is attached to the frame 2 at the rear of the vehicle body 1. The vehicle body 1 illustrated here has a rear structure as shown in FIGS. 2 to 5. Regarding the three axes X, Y, and Z shown in FIGS. 2 to 5, it is assumed that the vehicle is located on the horizontal plane, X is the vehicle width direction (the left side of the vehicle body is positive), and Y is the front-rear direction. (The rear of the vehicle body is positive), and Z indicates the vertical direction (the vertical upper direction is positive).

As shown in FIGS. 2 to 5, below the floor surface (rear floor panel) 3 at the rear of the vehicle body 1, a rear floor side member (vertical skeleton member) 21 extending in the vehicle length direction as a vehicle body frame 2 and the rear floor side member (longitudinal skeleton member) 21 thereof. It has a rear end cross member (end skeleton member) 22 that is coupled to the rear end of the rear floor side member 21 and extends in the vehicle width direction. The shipping bracket 10 is attached to a portion where the rear end cross member 22 at the rear end of the rear floor side member 21 is joined.

The rear floor side member 21 is configured as an inverted hat type in which the cross section of the hat type is turned upside down, both flange portions 21a and 21a are connected to the back surface 31 of the rear floor panel 3 by spot welding or the like, and the hat convex portion 21b is the rear floor. It protrudes below the panel 3. The rear end cross member 22 also has an inverted hat cross section, and the surface 22c of the hat convex portion 22b facing the front side of the vehicle body is joined to the tip of the rear floor side member 21 by spot welding or the like, and both flange portions 22a and 22a are formed. It is connected to the back surface 31 of the rear floor panel 3 by spot welding or the like.

The flat main surface portions 11m of the vehicle body mounting portions 11 of the panel members 10A and 10B are arranged so as to be separated from each other so as to sandwich the left and right side wall portions 21c and 21d of the rear floor side member 21, and both walls. It is joined to the outer surfaces of the portions 21c and 21d by spot welding or the like. Further, in this mounted state, the planar main surface portions 12m of the hooking portions 12 of the panel members 10A and 10B approach each other and are joined to each other by bolt fastening, spot welding, or the like.

In this way, the main surface portions 11m of the vehicle body mounting portions 11 of the panel members 10A and 10B are separated so as to face each other in the vertical direction, whereas the hooking portions of the panel members 10A and 10B are separated from each other. Since the main surface portions 12m of the 12 are close to each other in the vertical direction facing the vehicle length direction, the flat main surface portion 13m of the intermediate portion 13 is hooked to the main surface portion 11m of the vehicle body mounting portion 11. It is also inclined with respect to the main surface portion 12 m of the portion 12 (that is, it is inclined with respect to the vertical direction).

The other edge side linear bead edge portion 15c extending from the other end of 15a (the end portion located on the rear side of the vehicle body at the time of mounting) along the other edge side (rear edge side) of the intermediate portion 13 and the vehicle body mounting portion 11 is smooth. It is formed continuously in.

The edge portion 15E of the bead portion 15 is formed inside the panel members 10A and 10B along the front edge portion, the lower edge portion, and the trailing edge portion of the panel members 10A and 10B. It stands up against the main surface portion 10 m and increases the rigidity of the panel members 10A and 10B. Therefore, it functions as a reinforcing structure (reinforcing bead) of the panel members 10A and 10B. The inside of the bead portion 15 surrounded by the edge portion 15E (main surface portion 15 m of the bead portion 15) is formed in a planar shape or a smooth curved surface shape at a position shifted to the outer surface side from the main surface portion 10 m. ..

Further, on the outer periphery of the bead portion 15 (the edges of the panel members 10A and 10B), a flange portion 16 bent and formed on the outer surface side with respect to the bead portion 15 is formed. The flange portion 16 also stands up against the main surface portion 10m of the panel members 10A and 10B to increase the rigidity of the panel members 10A and 10B. Therefore, it functions as a reinforcing structure (reinforcing flange) of the panel members 10A and 10B.

Further, the flange portions 16a and 16b formed on a part of the flange portion 16, that is, the portion of the rear end cross member 22 on the rear edge side of the panel members 10A and 10B that abuts on the outer surface of the hat convex portion 22b, are the hat convex portions. It also functions as a mounting structure (mounting flange) that is joined to the outer surface of 22b by spot welding or the like.

As shown in FIG. 1, mounting holes (bolt holes) 17a and 17b for bolting the panel members 10A and 10B to each other are formed in the main surface portion 15m of the bead portion 15, and each mounting hole 17a is formed. , 17b are inserted with bolts (not shown) to fasten the panel members 10A and 10B to each other. The mounting hole 17b close to the hook hole 14 is formed in the reverse bead portion 18 formed so as to project toward the inner surface side contrary to the bead portion 15. The reverse bead portion 18 has a surface or a flat surface that protrudes inward as the distance from the hook hole 14 increases, and the hook hole 14 m and the circumference of the mounting hole 17b are reinforced by the edge portion 18E forming the reverse bead portion 18. ..
