The present invention relates to a front lashing hook of the front side member, and more particularly, by improving the front lashing hook to sufficiently absorb the impact force during the front impact (FRONT IMPACT), the amount of indirect impact delivered to the passengers in the room A front lashing hook on the front side member that can be reduced to improve safety.

In general, the vehicle body is an important factor to ensure the safety of the vehicle by testing the front and side impact to ensure the safety of the passenger in the event of a crash, and already in each country It is used as a large item such as import regulation by legalizing.

Conventional front side members for responding to the above regulations are shown in FIGS. 1 and 2, wherein the front side members 10 are formed by spot welding of side outer and side mermaid members 11 and 12. Under the front side member 10, a gusset 13 is mounted to complement the body coupling rigidity with the radiator support lower chamber (not shown) in the event of a frontal collision of the vehicle, and the bottom of the gusset 13 The front lashing hook is fixed by arc welding so that the vehicle can be fixedly carried by hooking the vehicle, for example, by ship, train or truck.

The front lashing hook is made of a round bar of steel material 14, the hook hook portion 15 is formed at the bottom of the round bar 14, the one side of the round bar 14 has the same diameter as the hook hook portion 15 The bracket 16 with the insertion hole 16a formed thereon is mounted.

The front lashing hook of the front side member configured as described above inserts a rope or hook into the insertion hole 16a of the bracket 16 so as to transport the vehicle, and at the hook hook portion 15 of the round bar 14. I carried it on foot.

However, since the round bar and gusset for transporting the vehicle wrap around the bottom of the front side member as described above, the gusset is not sufficiently distorted during the frontal collision of the vehicle, thus preventing the deformation of the front side member so that the impact force is indirectly transmitted. Of course, there is a problem that the stiffness of the round bar is reduced, in particular, passenger safety from the frontal collision can not be achieved. The present invention is to solve the above problems, the object of the present invention is to increase the cross-sectional area of the front side member In addition, by installing a reinforcing member to which the front lashing hook is coupled in the side mermaid member, the front lashing hook increases the rigidity and coupling of the front lashing hook as well as the amount of indirect shock transmitted to the passenger as the impact force is sufficiently absorbed in the front side member. Front side for reduced safety To provide a front hook member. Features of the present invention for achieving the above object, the side mermaid and the side outer member is spot-welded to form a front side member and the lower side of the front side member is mounted on the gusset and fixed to the bottom of the gusset A front lashing hook for carrying, comprising: a reinforcing member fixed to a front side member having an increased cross-sectional area and an inner side surface of a side mermaid member of the front side member so as to absorb an impact force during a frontal collision of the vehicle, and reinforcing body rigidity; It is characterized in that it comprises a front lashing hook is coupled to the reinforcement member and fastened by a pipe to carry the vehicle.

Hereinafter, preferred embodiments of the front lashing hook of the front side member according to the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 is a view showing a front lashing hook according to the present invention, the front side member 30 is made so that the side outer 31 and the side mermaid member 32 is welded to each other to increase the cross-sectional area, B-shaped reinforcement member 33 is fixed to the inner surface of the side outer member 31 by spot welding to reinforce the body rigidity, and to prevent bending at a right angle of the reinforcement member 33. 34 is fixed.

In addition, a through hole 33a is formed at one surface of the reinforcing member 33, and a front lashing hook 36 having a hook hook hole 35 is penetrated through the through hole 33a, and the front lashing hook ( The thread 37 machined therein is tightened with a pipe 37 machined with a female thread.

In the front lashing hook according to the present invention configured as described above, the reinforcing member 33 is fixed to the inner side surface of the side outer member 31 of the front side member 10 whose cross-sectional area is increased, and the penetration of the reinforcing member 33 is performed. The front lashing hook 36 penetrates the hole 33a, and the pipe 37 is connected to the reinforcing member 33 by welding at the upper end of the reinforcing member 33, and the rope and the hook are connected in the state of completion of coupling. It hangs on the hook hanger hole 35 of the front lashing hook 36, and carries a vehicle.

In addition, when the vehicle collides with the front of the vehicle from the outside, the cross-sectional area of the side outer and side mermaid members 31 and 32 is increased, so that the impact force is sufficiently absorbed to reduce the amount of impact transmitted indirectly to the passenger, and the front lashing hook 36 It is possible to increase the rigidity and bonding.

As described above, according to the front lashing hook of the front side member according to the present invention, the cross sectional area of the front side member is increased, and a reinforcing member to which the front lashing hook is coupled is mounted in the side mermaid member, so In addition to increasing stiffness and bondability, as the impact force is sufficiently absorbed from the front side members, the indirect impact delivered to the passenger can be reduced to improve safety.
