Description

Rigidity reinforcement structure against side impact of passenger cars

The present invention relates to a stiffness reinforcement structure for a side collision of a passenger vehicle, and more particularly, to strengthen the coupling force of the reinforcement panel located at the bottom of the floor panel, the side member and the cross member, and at the same time, to reduce the amount of sliding of the vehicle body during the side collision of the vehicle. The present invention relates to a stiffening reinforcement structure against side impact of a passenger vehicle additionally equipped with a reducing reinforcement panel.

In general, a collision of a vehicle can be classified into a frontal collision and a side collision, and the structures corresponding to the frontal collision of the vehicle are provided with various members and panels interposed in the bumper and the engine room, thereby ensuring some stability. However, the structures corresponding to the side collision of the vehicle include a door, a center pillar assembly and a side seal, but since they are located close to the vehicle compartment, it is difficult to safely protect the passengers from the side collision of the vehicle.

The structure corresponding to the side impact of the vehicle includes a side seal, a floor panel, a side member coupled to the bottom of the floor panel, a cloth member, and the like.

In addition, a support panel may be interposed between the side seal and the cloth member in order to cope with the side collision of the vehicle.

The side seal 101 is positioned below the door, and includes an outer panel 103 and an inner panel 105 that form a predetermined space by being combined with the outer panel 103 forming the exterior of the vehicle. Inside the side seal 101, there is a floor panel 107 that forms the bottom of the vehicle and is coupled to the inner panel 105 of the side seal 101.

Below the floor panel 107, the side member 109 spaced apart from the side seal 101 by a predetermined distance is long in the longitudinal direction of the vehicle.

The side member 109 is a "c" type member in which one side is opened to form the flange 111, and the flanges 111 at both ends are coupled to the bottom surface of the floor panel 107.

Inside the side member 109, a cross member 113 coupled to the floor panel 107 is interposed.

The cross member 113 is coupled to the bottom surface of the floor panel 107 in a state in which the cross member 113 is elongated in the vehicle width direction.

In the space formed by the floor panel 107, the side seal 101, and the side member 109, a support panel 115 prepared for side collision of the vehicle is interposed.

The support panel 115 is coupled to the bottom of the floor panel 107, the side member 109, and the cross member 113.

The support panel 115 is formed to have both side surfaces and a bottom surface, and is formed to be narrowed from the side seal 101 side to the side member 109 side.

Looking at the lower side structure of the vehicle in detail, the support panel 115 and the side member 109 and the cross member 113 mutual coupling structure are only the coupling force of their joint surfaces.

Therefore, in the event of a side collision of the vehicle, their engaging portions are prematurely damaged, so that the amount of impact applied to the vehicle body cannot be sufficiently absorbed.

As described above, the stiffness reinforcement structure of the side impact of the conventional passenger vehicle has a low mutual coupling force between the support panel, the side members and the cross members located at the bottom of the floor panel, so that the side of the lower portion of the vehicle body is easily affected by the impact force generated when the vehicle collides with the side. Pushed back, there is a problem that cannot guarantee the safety of the occupants.

The present invention is devised to solve the problems of the prior art as described above, an object of the present invention is to sufficiently absorb the impact force applied during the side impact of the vehicle from the lower side of the vehicle, and to reduce the amount of vehicle body sliding, the occupant's safety It is to provide a stiffness reinforcement structure for the side collision of a vehicle so as to ensure the safety.

In order to realize the above object of the present invention, a side seal comprising an outer panel forming an outer side of the door and an inner panel coupled to the inner side of the outer panel; A floor panel coupled to the inner panel of the side seal and forming a floor of the vehicle; A side member which maintains a constant distance from the side seal and is coupled to the bottom surface of the floor panel in a longitudinal direction of the vehicle; A rigid reinforcing member positioned in a space formed by the side seal, the side member, and the floor panel, both sides of which are coupled to the side seal and the side member, and an upper surface of which is coupled to the floor panel; A cross member positioned inside the side member in a vehicle width direction and coupled to a bottom surface of the floor panel; In order to reinforce the coupling force between the support panel and the side member and the cross member, it provides a stiffening reinforcement structure for the side collision of the passenger vehicle including a reinforcement panel coupled to the support panel and the side member and the cross member at the same time.

The stiffness reinforcement structure for the side collision of the passenger vehicle further has a rigidity that the reinforcement panel further installed to strengthen the bonding force of the support panel and the side member and the cross member, the reinforcement panel itself can absorb the impact force.

When a side collision occurs in the structure rather than the rigidity of the side collision of the passenger vehicle configured as described above, the side seal 1 is pushed into the inside of the vehicle to absorb the impact force primarily, and the floor panel 7 and the support panel 15 are absorbed. Residual impact force acts on them, and the second impact force is absorbed again, and the remaining residual impact force is applied to the side member 9 and the cross member 13 in sequence, thereby causing the side member 9 and The cross member 13 deforms and absorbs the impact force in a third order.

At this time, due to the strong impact force, each part coupling portion under the floor panel 7 tends to be damaged prematurely, and the deteriorated vehicle is severe enough, and in order to compensate for this, the support panel 15 and the side member 9 and The reinforcement panel 20 for reinforcing the engagement of the cross member 13 is coupled to prevent premature failure of each part.
