CONSTITUTION: A reinforcing structure for a tie down hook coupling part of a vehicle includes a reinforcing element(100) integrally formed with a bottom surface joining part(110) formed with a hook hole(111) and surface-joined with a lower flange of a rear seal side inner(300), and a top surface joining part(120) surface-joined to an upper flange of the rear seal side inner.

Description

Reinforced structure for combinating parts of tie down hook for automobiles}

The present invention relates to a tie-down hook reinforcement structure of an automobile, and in particular, when the vehicle is transported over a long distance by using a vehicle such as a ship or a vehicle transport vehicle, the vehicle is installed on the bottom of the vehicle body to fix the vehicle body to the vehicle. A device for reinforcing a tie-down hook fastening part, which improves durability of a tie-down hook fastening part of a vehicle, thereby securely fixing the vehicle body to a vehicle and preventing a vehicle body deformation due to torsion occurring in the vehicle body transport. will be.

In general, the tie-down hook fastening portion of the automobile is used to secure the vehicle by fixing the hooks fastened to the vehicle when the vehicle is transported over a long distance and the vehicle is transported to transport the vehicle from the automobile production factory to the consumer. It is a device installed to transport.

Since the tie-down hook fastening portion of the vehicle that fixes the vehicle body during acceleration and deceleration of the vehicle receives a large force, the reinforcing material is attached to the tie-down hook fastening portion, thereby preventing the body deformation due to the torsion generated during the vehicle body transportation.

1 to 4 is a conventional tie-down hook fastening portion reinforcement structure, Figure 1 is a perspective view showing a rear floor panel of a vehicle, Figure 2 is a perspective view showing a tie-down hook fastening portion reinforcement structure of a conventional vehicle. 3 is a cross-sectional view taken along line AA ′ of FIG. 2, and FIG. 4 is a perspective view illustrating a reinforcing member of a tiedown hook fastening portion reinforcing structure of a conventional vehicle.

As shown in FIG. 3, the tie down hook fastening part reinforcing structure of a conventional vehicle includes a reinforcing material formed of a lower surface joining part 11 in which a hook hole 12 is formed to be bonded to a lower flange of the rear seal side inner 30. 10).

The tie-down hook fastening portion reinforcement structure of the conventional vehicle configured as described above includes a hook hole formed in the reinforcement 10 when the vehicle is transported over a long distance by using a transport means such as a ship or a vehicle transport vehicle. The vehicle body is fixed by fastening to 12, and the bottom joint 11 of the stiffener 10 is attached to the lower flange of the rear seal side inner 30 located on the side of the rear side frame 20 by welding.

However, in order to increase rigidity, the tie-down hook coupling part of the conventional vehicle has two bottom flanges 11 of the rear seal side inner 30 located on the side of the rear side frame 20 in order to increase rigidity. Since the above welding method is used and the reinforcing material 10 is attached only to the lower flange of the rear seal side inner 30, there is a high possibility of deformation and cracking in the lower flange of the rear seal side inner 30.

The present invention is to solve the above problems, to improve the durability of the tie-down hook fastening portion of the vehicle to secure the vehicle body securely to the vehicle, a tie that can prevent the body deformation due to torsion occurs during the vehicle body transport It is intended to provide a down hook reinforcement structure.

The present invention is a hook hole is formed and the lower surface bonded portion that is bonded to the rear seal side inner lower flange; It is achieved by constructing a reinforcing member integrally formed with an upper surface joining portion that is face-bonded to the rear seal side inner upper flange.

Fig. 7 is a perspective view showing the reinforcing material of the tie down hook fastening portion reinforcing anchor of the automobile of the present invention.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 6, the tie down hook fastening portion reinforcement structure of the vehicle of the present invention, when the vehicle is transported over a long distance by using a vehicle such as a ship or a vehicle transport vehicle, the hook fastened to the vehicle means It is fastened to the hook hole 111 is located on the bottom surface, the hook hole 111 is formed is a lower surface joint portion which is welded to the lower flange of the rear seal side inner 300 located in the upper flange of the rear side frame 200 by welding ( 110); The technical features of the rear seal side inner 300 is composed of a reinforcing material 100 formed integrally with the upper surface joint part 120 welded to the upper flange by welding.

Hereinafter, the operation of the present invention will be described with reference to FIGS. 5 to 7.

The bottom joint 110 and the top side joint 120 of the stiffener 100 are simultaneously attached to the rear seal side inner 300 positioned in the rear side frame 200 by welding to be transmitted from the hook hole 111. By distributing the force evenly to the body, it is possible to prevent deformation and cracking at the tie down hook joint of the car, and to simplify the welding work, and to improve the durability to secure the body securely to the vehicle. To prevent the deformation of the body caused by torsion during transportation.

The present invention as described above is to improve the durability of the tie-down hook fastening portion of the vehicle to secure the vehicle body securely to the vehicle, it is an invention that can prevent the deformation of the vehicle body due to the torsion generated during the vehicle body transport.
