[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping bracket provided on a vehicle frame, and more particularly to a reinforcing structure thereof.

[0002]

2. Description of the Related Art When a vehicle is transported by loading, it is necessary to fix the vehicle so as not to move on the ship. Therefore,
As shown in FIGS. 4 and 5, the lower bent portions 1 b, 1, 1, 1 a, 1 b of the front end cross member 1 are welded to the front ends 2 a, 2 a of the front side member 2.
The shipping brackets 3 and 3 are welded in the vicinity of b, and hooks (not shown) provided on the floor are hooked on the shipping brackets 3 and 3 to lock the vehicle. Alternatively, as shown in FIGS. 6 and 7, there is also a structure in which the front end gusset 4 has a box sectional structure and the upper end 4a is welded to the front end 2a of the front side member 2.

[0003]

However, in the former case, when inputs in the front-rear direction indicated by arrows F and R are applied to the shipping bracket 3, the distance from the front end of the front side member 2 to the shipping bracket 3 is long. Since the offset is large, the front end cross member 1 is largely deformed back and forth as shown by a two-dot chain line.
Further, the front side member 2 is formed such that the front portion 2b is easily deformed in order to absorb and relax the energy at the time of collision. Therefore, when the front end cross member 1 is deformed back and forth by the input from the shipping bracket 3, there is a problem that the joint between the front end 1 a of the front end cross member 1 and the front end 2 a of the front side member 2 is deformed. is there.

Further, the front end gusset 4 having a box cross-sectional structure like the latter has a very high rigidity, so that the front portion 2b of the front sand member 2 is hardly crushed. As a result, when the front side member 2 collides, Energy cannot be absorbed and alleviated. There are also problems such as an increase in weight and an increase in cost. The present invention has been made in view of the above points, and an object of the present invention is to provide a shipping bracket that can effectively absorb energy at the time of a collision and has less deformation with respect to an input in a front-rear direction.

[0005]

According to the present invention, in order to achieve the above object, the lower end has a predetermined distance from the front end of the front side member, the lower end being located below the front end cross member of the frame. A gusset is welded to the inner surface of the part and provided diagonally forward and downward between the two, and a locking member is provided at the lower end of the gusset and is provided with a locking hole. Things.

[0006]

The locking member welded to the gusset is locked by hooking a hook provided on the floor surface into the locking hole. A gusset is reinforced between the front end cross member and the front side member, so that the front end cross member is prevented from being deformed by a front-rear force input to the locking member. On the other hand, the upper end of the gusset is fixed to the front side member at a predetermined distance from the front end, and the front side member is a crushable area from the front end to the gusset, effectively saving energy at impact. It becomes possible to absorb.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. 1 to 3, both ends 1a, 1a of the front end cross member 1 are welded to the front ends 2a, 2a of the left and right front side members 2, 2, and both ends of the gussets 6, 6 are interposed therebetween. Welded. The gusset 6 has, for example, an L-shaped cross section (FIG. 3), and a locking member such as a bar 7 is welded to the inside of the bent portion over substantially the entire length. The lower end 7a of the bar 7 is bent as shown in FIG. 1 to form a locking hole (hereinafter referred to as a "locking hole 7a").

The upper end of the gusset 6 is welded to the inner surface of the front side member 2 at a predetermined distance d (FIG. 1) from the front end 2a, and the lower end is formed on the lower side (bent portion) of the front end cross member 1. ) 1b via a bracket 8. That is, the gusset 6 is disposed between the lower portion 1b of the front end cross member 1 and the inner surface of the front side member 2 so as to be substantially along the front end cross member 1, and the upper end is located rearward relative to the lower end. It is located at the front and inclined downward. As a result, the horizontal offset δ (FIG. 2) of the locking hole 7a is reduced. The locking hole 7a of the bar 7 is located slightly below the lower portion 1b of the front end cross member 1. Thus, the shipping bracket 9 is configured. Incidentally, the shipping bracket 9 may be attached to the frame as an outfitting part from the beginning.

The operation will be described below. Vehicle (not shown)
The hook provided on the floor surface (not shown) is hooked and locked in the locking hole 7a at the lower end of the bar 7 of the shipping bracket 9 shown in FIG. The bar 7 is welded to the gusset 6 and the gusset 6 has an L-shaped cross section (FIG. 3), so that the gusset 6 has high rigidity, and has a lower end on the front end cross member 1 and an upper end on the front side. Since the front end cross member 1 is mounted on the member 2 so as to support the front end cross member 1, the force input to the bar 7 in the front-rear direction indicated by arrows F and R is applied to the front side member 2.
Tell Thereby, the deformation of the front end cross member 1 in the above-mentioned direction is prevented.

On the other hand, since the upper end of the gusset 6 is welded rearward at a distance d from the front end 2a of the front side member 2, the front end 2 of the front side member 2 is welded.
The portion b may be a crushable area that is easily deformed, and therefore, the portion 2b of the front side member 2 may be crushed at the time of a collision to effectively absorb energy. This prevents the front side member 2 from being deformed during shipping while holding the crushable area.

[0011]

As described above, according to the present invention, the lower end is welded to the lower portion of the front end cross member of the frame, and the upper end is welded to the inner surface of a portion at a predetermined distance from the front end of the front side member. The gusset is provided with a gusset obliquely provided forward and downward between the two and a locking member welded to the lower end of the gusset and provided with a locking hole. Nevertheless, it is possible to prevent the front end cross member from being deformed at the time of shipping while giving the front side member a crushable area, and it is possible to provide a lightweight and inexpensive structure.
