Description

Reinforcement structure of center pillar}

The present invention relates to a center pillar reinforcement structure, and more particularly, to a coupling part and a vehicle body coupled to an upper part of a roof rail by connecting a reinforcing connection member to an inner side of a reinforcement center pillar so that another space portion may be formed inside the center pillar. It relates to a center pillar reinforcement structure to improve the connection rigidity by allowing the connection state of the coupling portion of the lower portion to be tightly coupled.

The general body structure is a basic structure of the vehicle body, which is composed of an underfloor skeleton supporting an engine or a chassis part, a filler side, a doyside skeleton such as a roof rail, and a panel part called a floor and a roof.

The filler needs to be concerned about securing the driver's front or side clock and the safety of the rollover, and to reduce the air resistance and the wind noise, it is necessary to reduce the surface of the front pillar and the door to reduce the flash surface. .

The main role under the front pillars and the center pillar is the support of the doors, since when the door is opened with a strong force, or when the door is pressed down with a strong force, a great force is applied to the door hinge and check link attachments so that the reinforcement is installed. It is necessary to sufficiently secure the surface stiffness and strength of the attachment portion.

Therefore, the center pillar may need to be thinned for designing a watch or securing a watch. However, since the seat belt anchorage is usually set at this portion, a reinforcing panel may be added in order to secure the strength.

Referring to Figures 1, a, b, c showing the conventional centrifugal structure as follows.

1a

Conventional centrifugal structure has a rear fender (3) is installed in the center of the vehicle side door is mounted in the center of the central pillar to be separated from the front and rear doors to be able to absorb the external shock, and the The reinforcement center pillar (1) is bent in multiple stages to be in close contact with the inner wall surface of the rear fender (3), and the end is connected to the inner left and right of the reinforcement center pillar (1) can be formed space The plate anchor 2 and the center pillar 4 are connected to the outside of the plate anchor so as to prevent external shock from being transferred into the vehicle compartment.

The conventional center pillar structure configured as described above has a rear panda (3) and a reinforcement center pillar (1) to facilitate opening and closing of the door with the front and rear doors as a boundary, and to prevent the impact of the door opening and closing to be transmitted to the interior of the vehicle. The inner side of the reinforcing center pillar (1) to form a constant space between the plate anchor (2) and the center pillar (4) connected to the inside of the reinforcement center pillar (1) so that the impact energy can be absorbed in the space side The vibration caused by the impact from the can be attenuated.

However, the conventional center pillar structure has a problem in that the joints of the upper and lower portions of the rear panda and the center pillar are coupled to the vehicle body, so that when the impact is applied from the outside, the coupling portion is deformed or deformed or damaged.

The present invention is intended to solve the problems of the prior art, the purpose of which is coupled to the upper portion of the roof rail by connecting the reinforcing connection member to the inner side of the reinforcement center pillar so that another space portion can be formed inside the center pillar. It is to improve the connection rigidity by allowing the connection state of the coupling portion of the lower portion to be coupled to the vehicle body to be close.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

The present invention relates to a structure for reinforcing the structure of a centrifugal pillar that borders a vehicle door. As shown in FIGS. 2A to 2E, the present invention is installed at a center at which a door of a side of a vehicle is mounted to distinguish a front and rear door. The rear fender 13 is bent in multiple stages to the outside of the center pillar to absorb external shocks, and the reinforcement center pillar is bent in multiple stages to be in close contact with the inner wall surface of the rear fender 13. And a reinforcing connection member 30 formed at a plurality of bends so that ends are connected to left and right ends of the reinforcement center pillar 10 so that a space is formed inward, and coupled to left and right ends of the reinforcing connection member. The center pillar 14 is connected to the outside of the vehicle to prevent the shock from being transmitted.

Referring to the effects of the present invention configured in this way in detail as follows.

The present invention relates to a structure for reinforcing a structure of a centrifugal pillar bounded by a vehicle door. As shown in FIGS. 2A to 2E, a reinforcement center pillar 10 having a similar bending formation to a rear fender 13 is provided. The left and right ends are closely connected to each other so as to absorb external shocks by the coupling rigidity, and the left and right ends of the reinforcing connection member 30 are coupled to the inside to be coupled to the left and right ends of the reinforcement center pillar 10. The space is formed so that the impact energy transmitted from the reinforcement center pillar 10 side can be absorbed in the space.

Here, the reinforcing connection member 30 is a center fill line 14 by forming a space at a predetermined distance from the reinforcing connection member 30 while the center fill line 14 is closely connected to the left and right ends of the other side, Is to absorb the remaining impact energy transmitted through the reinforcing connection member 30 to attenuate the impact energy delivered to the vehicle interior.

Therefore, the centafil is to prevent the twisted or broken or deformed even when the impact is transmitted from the outside to the vehicle body coupled to the upper and lower by further connecting the reinforcing connection member 30 to the reinforcement center pillar (10).

The present invention acting as described above connects the reinforcing connection member to the inside of the reinforcement center pillar so that another space portion can be formed in the center pillar, and the coupling portion coupled to the upper portion of the roof rail and the coupling portion of the lower portion coupled to the vehicle body. By making the state closer, the connection rigidity is improved, so that even if an impact is transmitted from the outside to the vehicle body, it is prevented from being twisted or damaged.
