Description

Front body reinforcement for automobiles.

The present invention relates to a front body reinforcement device for automobiles, and more particularly, to provide a front body reinforcement device having a configuration that can reduce the injury of the occupant to the minimum by dispersing and absorbing the collision energy generated during the vehicle front collision.

The front body of the vehicle makes up the engine room and allows the engine and various engine-related parts to be installed.In the event of a collision, the front body of the vehicle effectively absorbs and distributes the collision energy to prevent injuries of the occupants in the vehicle. It should be configured to the minimum.

However, since the reinforcing means for absorbing and dispersing the collision energy is not found in the conventional front frame of the conventional vehicle, collision energy is transmitted to the interior of the vehicle in case of a collision, causing serious injury to the occupant.

In recent years, by resolving these problems, a reinforcing device has been developed and mounted on the front frame to effectively absorb the collision energy generated during a collision and to spray it throughout the front frame.

The reinforcement device is divided into a method of fixing in the longitudinal direction on the dash panel that partitions the engine room and the vehicle compartment and a method of fixing to protrude forward across the front body and the side body.

In the case of the reinforcement fixed on the dash panel, it is troublesome to go through several simulations to properly absorb and disperse the collision energy.

In case of the reinforcement fixed between the front body and the side body, oxygen or electric welding is performed between the reinforcement and the body, so that the labor time is increased and additional equipment must be provided, and harmful gas is generated during the welding process. Problems arise such as poor working environment and conditions.

Accordingly, in the present invention, in order to solve the above problems, the reinforcement is separated into an upper panel fixed to the front body and an adapter bracket fixed to the side body and a lower panel fixed to the upper panel and the adapter bracket and spot welding them (spot; SPOT) Welding), which can contribute to reduction of assembly labor, light weight and automation.

Conventional reinforcement (1) for absorbing and dispersing the impact force of the front body in the event of a collision is shown in Figures 1 to 3, and looking at this, as shown in Figure 1 dashes that partition the front body 2 and the vehicle interior In the case of fixing on the panel (3), it should be installed after obtaining the optimal data through a large number of virtual experiments to maintain accuracy.

Therefore, there is a problem that the preparation process for mounting the reinforcement (1) is complicated and bears a lot of time and development costs.

And when the reinforcement (1) is fixed so as to protrude forward over the front body (2) and side body (4) phase as shown in Figure 2 because the reinforcement (1) is a weight body oxygen welding to fix in a solid state However, because it is fixed by electric welding, it is necessary to have dedicated equipment and professional manpower, as well as the working environment due to harmful gas generated during welding.

Above all, each body for constituting the vehicle body is automatized to a spot, while only the reinforcement is fixed by oxygen or electric welding, and thus the above-mentioned problems cannot be automated.

In the present invention in view of the above problems, as shown in Figs. 4 to 9, the reinforcing member 10 and upper panel 11 and lower so as to have the same conditions as the work constituting the vehicle body by occupying each body Separating into the panel 12 and the adapter bracket 13 to enable the connection with the vehicle body automation and to simplify the assembly process of the reinforcement (10).

The upper panel 11 of the reinforcing member 10 has a bent portion 15 in the longitudinal direction for strength reinforcement to fix the spot welding together when configuring the sub-assembly 17 of the front body 16, adapter bracket 13 ) Is fixed to the spot when configuring the side body (18).

The lower panel 12 is the upper panel 11 and the adapter bracket 13, the front body 16 and the side body 18 is fixed (coupled) by spot welding in accordance with the body assembly process after the upper panel ( 11), the adapter bracket (13) and the front assembly (16) to the sub-assembly (17) of the spot welding to be fixed.

The adapter bracket 13 and the lower panel 12 are bonded to the side body 18, the subassembly 17, the lower panel 12, the upper panel 11 and the subassembly 17, and the adapter bracket 13. It is configured to be integrally provided with the bent joint surface (20, 21, 22, 23) to provide ease of.

Looking at the assembly embodiment of the present invention as described above;

EXAMPLE

When constructing the front body 16, the upper panel 11 of the reinforcing material 10 is welded to the sub-assembly 17 of the front body 16 to be integrally formed, and when the side body 18 is formed, the reinforcing material The adapter bracket 13 of (10) is welded and comprised integrally.

In this state, when the front body 16 and the side body 18 are spot welded to each other according to the body welding process, the upper panel 11 and the sub panel are joined using the joining surfaces 20 and 21 of the adapter bracket 13. Spot weld the assembly (17) and the adapter bracket (13).

As described above, the upper panel 11 and the adapter bracket 13 of the front body 16, the side body 18 and the reinforcement 10 are integrally coupled in the vehicle body construction process, and then the lower panel of the reinforcement 10 12) may be welded to the subassembly 17, the upper panel 11 and the adapter bracket 13 of the front body 16, and fixed.

When fixing the lower panel 12, the joint surfaces 22 and 23 are connected to the sub-assembly 17, the upper panel 11, and the adapter bracket by using the joint surfaces 22 and 23 formed on the lower panel 12. The spot welding is carried out in a state where it is brought into contact with the joining surfaces 20 and 21 of (13).

When the reinforcement 10 is fixed over the front body 16 and the side body 18 as described above, the present invention can achieve vehicle weight reduction by configuring the reinforcement 10 in a thin plate having a thickness almost equal to that of the vehicle body panel. As a result, work is performed in conjunction with an automated process that combines each body constituting the vehicle body, thereby eliminating the need for a separate dedicated equipment or labor.

The present invention as described above has the effect of eliminating the additional process and the burden of equipment costs as well as the improvement of the working environment by the automation and simplification of the reinforcement in conjunction with the body assembly line.
