Abstract

PURPOSE: A reinforcing structure for an intermediate stay of a vehicle is provided to restrain the deformation of the holding parts of the striker bracket and the intermediate stay due to an impact load generated when opening or closing doors and prevent the invasion of side vehicle bodies due to side impacts by effectively absorbing the impact. CONSTITUTION: In a reinforcing structure for an intermediate stay of a vehicle, a striker bracket(20) is formed with a protruded reinforcing part(25) in the center in a closed sectional surface and folded upper parts at both sides, so that the striker bracket is positioned in a space of a closed sectional space formed between inner and outer panels(11,12) to be mounted to side surfaces of a vehicle, and an intermediate stay(10) is formed with closed sectional surfaces at upper and lower parts of the inside.

Description

Reinforcement structure of car middle pillar

The present invention relates to a reinforcing structure for improving the rigidity of the intermediate pillar is installed in the center of the vehicle, in particular, to effectively intrude the door and the intermediate column into the vehicle compartment during side impact of the vehicle to enhance the reinforcement against impact energy It relates to a reinforcement structure of a vehicle intermediate pillar to suppress.

In general, the vehicle body structure of the side portion of the vehicle, the opening is formed between the front pillar (center pillar) and the center pillar (center pillar) and rear pillar (rear pillar), the door is installed to open and close the opening, the pillars A roof rail which forms an outer portion of the roof is connected to the upper end, and a floor panel and a side sill, which form a bottom portion of the vehicle, are connected to the lower end of the pillars.

Here, the conventional reinforcement structure of the intermediate pillar of the vehicle is closed as the inner panel (11) and the outer panel (outer panel 12) bent as shown in Figures 1 and 2 with a predetermined space It is coupled to the surface, one end of the striker bracket 20 is mounted between the inner panel 11 and the outer panel 12 in the closed end surface, the inner side of the outer panel 12 in contact with one side of the striker bracket ( 20) is mounted.

The reinforcement structure of the conventional automobile intermediate pillar configured as described above includes a hinge mounted at one side of the door installed at the side of the vehicle and mounted at the striker bracket 20 in contact with the inner surface of the outer panel 12. The door installed on the side of the vehicle is prevented from being opened while driving, and in the event that a collision accident or the like occurs while driving the vehicle, the impact energy is absorbed by the outer panel 12, so that the door is a side structure. Is prevented from entering the room and absorbs impact energy, thereby suppressing deformation of the side vehicle body and protecting the occupant of the room.

However, the conventional reinforcement structure of the middle pillar of the vehicle is the door as the outer surface of the striker bracket 20 to the hinge is installed on one side of the door is fastened to one side of the outer surface of the panel 12 in close contact. When the opening and closing of the striker bracket 20, the shock is transmitted, the outer panel 12 forming the striker bracket 20 and the intermediate pillar 10 had a problem that the deformation occurs.

Accordingly, an object of the present invention is to close the left and right sides of the bent to form a flange, a striker bracket formed with a reinforcing part protruding in the center, the outer panel and the inner panel is mounted to complement the conventional problems as described above To provide a reinforcement structure of a vehicle intermediate pillar mounted on the inside of the surface to effectively absorb the impact energy generated when the door is opened and closed, to suppress the deformation of the intermediate pillar by the impact energy generated when the door is opened and closed. have.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail. In the detailed description of the present invention, the same reference numerals are used for the same parts as in the prior art. As shown in FIG. 3, the reinforcing structure of the automobile intermediate pillar of the present invention is that the bent inner panel 11 and the outer panel 12 are coupled to the closed end surface with a predetermined space, and the inside of the closed end surface. Reinforcement portion 25 is formed in the protruding portion in the center and the left and right sides of the upper end is bent to the striker bracket 20 in contact with the inner panel 11 and the outer panel 12 is a basic feature in its technical configuration.

In the present invention configured as described above, one side portion is mounted in contact with the outer panel 12 in the transverse direction to the closed end surface formed in the intermediate column 10, and the upper end portion is mounted with the outer panel 12 and the inner panel 11 Attached to the mounting portion, the respective closed cross-sections are formed in the upper and lower portions of the intermediate column (10).

Therefore, in the present invention, the striker bracket 20 mounting surface for opening and closing the door installed at the side of the vehicle is supported by the reinforcing portion, and each closed end surface is formed at the inner upper and lower portions of the intermediate pillar, The impact load generated at the opening of the door suppresses deformation of the intermediate pillar 10 as well as the mounting surface of the striker bracket 20, effectively cushioning the impact, and opening and closing the door, as well as during side collisions. By preventing the column from being damaged and flowing into the vehicle compartment, there is an effect of improving safety of the occupants.

As described above, in the present invention, the closed end surfaces formed in the middle column 10 are formed at the top and the bottom, respectively, and one side is mounted to be supported at one side of the outer panel 12 to be generated when opening and closing the door. It is very useful to prevent the mounting surface and the intermediate column of the striker bracket 20 from being deformed by the impact energy, as well as to suppress the invasion of the side vehicle body and effectively cushion the impact even in the case of the side stratification.

Claims (1)

In the reinforcement structure of the middle pillar of the vehicle, which is spaced apart by a predetermined space between the bent inner and outer panels 11 and 12 to form a closed cross section and brackets are mounted therebetween, the striker bracket 20 protrudes from the center portion. The reinforcement structure of the vehicle intermediate pillar, characterized in that the reinforcement portion 25 is bent to the left and right sides and mounted on the inner and outer panels (11, 12).
