Reinforcement structure of car front pillar lower panel

The present invention relates to a reinforcement structure of a front pillar lower panel in which a front door of a vehicle is hinged, one end of a front panda panel is bolted, and side seals supporting lower ends of the front door and the rear door are extended and coupled. Particularly, the connection between the reinforcement lower panel reinforcing the front pillar panel and the reinforcement rocker panel reinforcing the side seal inner panel is prevented from being deformed and deformed during frontal collision of the vehicle. The first and second hinge support panels are installed on the inner surface of the reinforcement lower panel, and the first and second hinge support panels are held at regular intervals and are orthogonally coupled to the reinforcement lower panels. The front pillars, the impact energy transmitted to the front pillars in the event of a front collision It effectively absorbs and absorbs the lower part of the lower part, and prevents the lower part from being deformed, thereby preventing the side seal connected to the lower part from being deformed toward the interior of the car. The present invention relates to a reinforcement structure of an automobile front pillar lower panel that enables passengers in a vehicle to safely open and exit a door in a car accident.

In general, the vehicle body is installed on the frame, or directly connected to the suspension system to accommodate people or cargo, and is separate from the frame and integral with the frame, such body is the front as shown in FIG. The front body 20 is divided into an under body 22, a side body (not shown), and a rear body 24. The front body 20 ) Is composed of first and second front pillars 10 which form the support of the front window including the engine room from the front fore end of the vehicle body, and the design of the front body 20 is In order to alleviate the impact force in the room in the event of a frontal collision of the vehicle, the impact energy is sufficiently absorbed through proper stiffness adjustment in the front and rear directions. In addition, the engine and steering system are designed to minimize the amount of intrusion into the vehicle interior during a collision. When designing the engine room, the inherent performance protection, workability, maintenance and maintenance of the size of the relevant parts according to the type of engine, the wire harness mounting path, the battery mounting position, and the position of other auxiliary parts It is considered and manufactured to properly block the inflow of noise into the car interior.

Since the underbody 22 is directly mounted with a driving device such as a suspension device of an engine mounting transmission rear wheel driver and is directly subjected to an external force by this, the member has a structure reinforced with an element element. Unlike trucks, passenger cars have a three-dimensional structure without a frame, because the weight of the vehicle is lighter than the frame type and integrated with the body other than the frame. Because of its workability and mass productivity. However, since the vibration of noise in the power transmission device is directly transmitted to the body, it is necessary to prevent the soundproof soundproofing. For this purpose, the floor surface is manufactured by considering beads and members. In addition, when setting spare tire and fuel tank mounting position on the trunk floor surface, it is designed and manufactured in consideration of energy absorption and fuel leakage prevention in case of collision.

The side body is a structural member forming a side portion of the vehicle, and serves to suppress deformation of the vehicle during vehicle overturning and side collision and to secure durability. The belt line top cross section of each pillar 10, 12, 14 tends to be possible to widen the field of view, but the bending and torsional stiffness of the body should be taken into account. The lower end portion of the belt line has a larger cross section compared to the upper portion, and many parts of the belt change rapidly, but are manufactured in consideration of the decrease in rigidity of the door because it supports the door. In addition, in the vicinity of the rear wheel of the side body, since the negative pressure of the outer surface is generally high during driving, a ventilation hole is provided in this area.

The rear body 24 is located at the back of the passenger compartment, and is generally composed of a portion of the cargo compartment and a portion including a side body and a portion of the underbody 22. The rear body 24 is structurally a cabin and a trunk room. It is completely separated by this panel, and is divided into a structure in which the left and right side bodies are attached, and a structure in which the cabin and the luggage compartment are not separated.

Self-panel and seat back supports contribute significantly to the torsional stiffness of the car body when the cabin and the trunk room are separated. However, vehicles that do not distinguish between the cabin and the trunk room do not have a self-panel and seat back support. Has a double structure or a fully closed cross section.

In the figure, 16 is a side seal, and 18 is a roof panel.

The lower end of the front pillar 100 that forms the support of the front window including the engine room from the front fore end of the conventional vehicle body, the front door is hinged as shown in Figure 2, one end of the front panda panel is bolted The side seal 160 supporting the lower ends of the front door and the rear door is extended and coupled.

Reinforcement lower panel 100-1 for reinforcing rigidity is integrally joined to the front pillar panel (not shown) at the lower end of the front pillar 100 by welding, and the reinforcement lower panel The horizontal extension portion of the (100-1) is connected to the reinforcement rocker panel (160-1) for reinforcing the rigidity of the side seal inner panel (not shown) is coupled, such a conventional front pillar (100) Although the side seal 160 is formed and manufactured to have rigidity corresponding to the frontal collision of the vehicle, the side seals connected to the front pillar 100 may not effectively absorb impact energy due to the collision. Impact energy is transmitted to the 160 and the roof panel and the center pillar panel such that each connection part is deformed.

More specifically, the front pillar reinforcement lower panel 100-1 and the side seal reinforcement rocker panel 160-1 due to the impact energy applied to the A portion of the front pillar 100 during the frontal collision of the vehicle. ) Moment is generated in the B part which is contacted and fixed by contacting, and the reinforcement rocker panel 160-1 is deformed in the direction of arrow C, and the front door is inserted into the gap created by the deformation. Thereafter, the driver and the passenger seat of the passenger seat could not open the door by magnetic force and thus could not escape out of the car.

In addition, there was a problem such as a large accident caused by the fire and explosion that occurs continuously after the frontal collision of the car.

In other words, the front bumper, the front body and the front wheel, etc. are deformed and intruded toward the interior of the vehicle during a front collision, and the impact energy is transmitted to the lower end of the front pillar 100, that is, the arrow A direction and part. In this case, the front pillar 100 is also deformed to some extent to absorb and relax the impact energy. However, the front pillar 100 does not absorb all the shock energy to the side seal 160, and at the same time, a moment such as arrow C is generated in the B portion. As the side seal 160 is deformed, the front door hinged to the front pillar 100 is inserted into the deformed gap so that the front door cannot be opened by the driver and the passenger of the passenger seat by themselves. The driver and the passenger in the passenger seat had problems such as not being able to escape out of the car.

The present invention has been made in consideration of the above circumstances, and its purpose is to connect the front of the vehicle to the rain force lower panel which reinforces the front pillar panel and the rear force rocker panel which reinforces the side seal inner panel. The first and second hinge support panels are installed on the inner surface of the reinforcement lower panel of the front pillar so as to prevent them from being deformed and deformed during a collision, so that the first and second hinge support panels are maintained at a constant interval. At the same time, by combining the reinforcement lower panel orthogonal to each other, the impact energy transmitted to the front pillar in the event of a frontal collision of the vehicle is effectively absorbed by the lower portion of the front pillar, and at the same time, the lower portion is prevented from being deformed. The side seals connected to the lower end being deformed toward the interior of the car And by ensuring that anti should not at the same time replace the deformed portion of the front door by the modification to provide a reinforcing structure of the vehicle front pillar lower panel that can allow a car accident the passenger cabin can come to open the safe door.

In order to achieve the above object, the present invention maintains a constant distance between the first and second hinge support panels on the flat plate on the inner surface of the reinforcement lower panel for reinforcing the inner panel of the front pillar. It is achieved by providing a reinforcing structure of an automobile front pillar lower panel which is combined orthogonally with the reinforcement lower panel in a vertical state.
