Abstract

The present invention, in the structure of the conventional center filler reinforcement for automobiles, the front end of the counterpart vehicle directly hits this place in the event of a side collision, so that both sides of the outer side frame and both sides of the center pillar reinforcement buckles, and the closed section is instantaneously disappeared. There is a problem that there is a risk of injury to people due to the enormous bending deformation, in order to solve this problem, in a vehicle including a center filler reinforcement, the center pillar 40c of both sides of the center pillar reinforcement 40, a plurality of recesses ( 42) provides a center pillar reinforcement of an automobile, characterized in that formed.

[Industrial use]

The present invention relates to a center pillar in a side body of a vehicle, and more particularly, to change the structure of the center pillar reinforcement to increase the rigidity of the center pillar so that the center of the automobile can be reduced in the event of side collision. It relates to a filler reinforcement.

[Prior art]

In general, a vehicle is composed of a chassis that forms an important part of a vehicle, and a body installed on the chassis to constitute a driver's seat or a cabin, and a frame body that separates a body and a frame, and a body and a frame. It can be classified as a structural body, and most of the current cars use a monolithic body.

The chassis is composed of an engine, a power transmission device that receives the power of the engine, a steering device that adjusts the driving direction of the vehicle, a suspension device that blocks shock from being transmitted to the vehicle while driving, and the like. .

The body is the main part of the human body, and the exterior parts such as doors and fenders are attached to the body to form the exterior of the car, and the interior parts such as seats are mounted inside, and the safety, space, and comfort required for the driver and the passengers. It should have elements such as

The body is broadly classified into a front body, an under body, a side body, and a rear body, and the center of the side body is a filler, and the filler plays a very important role in maintaining the rigidity of the entire body.

In particular, in recent years, the top of the filler is getting thinner because each filler tries to widen the clock by making the window as large as possible.

As shown in FIG. 1, the pillar is composed of a front pillar P1, a center pillar P2, and a rear pillar P3.

In the related art, the structure of the center pillar of an automobile will be described with reference to FIG.

The bent portion of the center pillar reinforcement 4 is joined to the outer side of the bent portion of the inner center pillar panel 2, and the outer side frame 6 is joined to the outer side of the bent portion of the center pillar reinforcement 4.

The center pillar reinforcement 4 will be described with reference to FIG. 3. The upper portion 4a coupled to the loop side, the lower portion 4b coupled to the underbody side, and the upper portion 4a and the lower portion 4b It consists of a central portion (4c) for connecting, the central portion (4c) of the center pillar (4) is bent to both sides.

The center pillar reinforcement 4 forms a closed section together with the outer side frame 6 and plays a very important role in the support stiffness and side impact performance of the roof and door.

However, in the structure of the center pillar reinforcement of the conventional vehicle described above, the front end of the counterpart vehicle directly hits this place during a side collision, so that both sides of the outer side frame and both sides of the center pillar reinforcement are buckled and bent momentarily. There is a problem that there is a risk of human damage to the extinction caused a huge bending deformation.

Summary of the proposal

Accordingly, the present invention is devised to solve the above problems, and an object of the present invention is to provide a center pillar reinforcement of an automobile that can prevent the degradation of rigidity during side collisions and promote passenger safety.

In order to achieve the above object, the present invention provides a center pillar reinforcement of a vehicle, characterized in that a plurality of recesses are formed on both sides of the center of the center pillar reinforcement.

In the structure of the center pillar reinforcement of the vehicle as described above, it is possible to prevent the sudden stiffness of the center pillar during side impacts, thereby promoting the safety of the passengers.

EXAMPLE

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object.

In the present embodiment, the same configuration as the prior art has the same name and the same reference numerals and description thereof will be omitted.

4 is a perspective view showing an embodiment to which the present invention is applied and described with reference to the center filler reinforcement as follows.

A plurality of recesses 42 are formed on both side surfaces of the center portion 40c connecting the upper portion 40a and the lower portion 40b of the center pillar reinforcing material 40.

Accordingly, since the center pillar reinforcing member 40 is formed at the center pillar reinforcing member 40 at the time of side impact of the vehicle, the rigidity of the center pillar can be prevented from suddenly disappearing, thereby reducing the deformation of the center pillar portion.

According to the present invention as described above, there is an advantage that can reduce the deformation of the center pillar portion at the time of the side collision to ensure the safety of the passengers.

[effect]

In the above description of the present invention has been described only one embodiment, as can be seen in the appended claims, those skilled in the art to which the present invention belongs can be modified without departing from the spirit of the present invention and such modifications I will understand that it belongs to the scope of the invention.

Claims (1)

In a vehicle comprising a center filler reinforcement, the center pillar reinforcement of the vehicle, characterized in that a plurality of concave portions 42 are formed on both sides of the center portion (40c) of the center filler reinforcement (40).
