Description

Reinforcement structure of roof panel

The present invention relates to a reinforcing structure of a roof panel that forms an interior cover portion of a vehicle body, and to a reinforcing structure of a roof panel which improves the safety of the occupant by improving the support strength of the roof panel and the strength in the transverse direction.

As is well known, the vehicle body forms the skeleton of the vehicle, and must have sufficient strength to support the equipment to be mounted, and to sufficiently withstand external forces such as impact or bending, torsion, tension, and vibration. In consideration of fuel efficiency, the self-weight is preferably as light as possible.

On the other hand, the roof panel forms a cover portion in the interior of the vehicle. When the prior art is described with reference to FIGS. 1 and 2a and 2b, the front header 20 in which the front end surface of the roof panel 10 is mounted on the vehicle body is described. ), The rear end surface of the roof panel 10 is fixed to the rear header 30 mounted on the vehicle body, and the front pillars 50 and 50 'and the center pillar 60 are provided to face the upper sides of both sides of the vehicle body. 60 ') and the upper ends of the rear pillars 70 and 70' form a structure in which edge portions of the roof panel 10 corresponding to the rear pillars 70 and 70 'are fixed. In addition, since the plate-shaped roof panel 10 is easily deformed even with a small external force, as shown in FIGS. 2A and 2B, the roof panel 10 includes a first reinforcing material 40 having a cross shape in a transverse direction of the vehicle. Both ends of the first reinforcement 40 are fixed to the center pillars 60 and 60 ', respectively, in a state in which they are disposed to be in contact with the bottom of the intermediate position of 10, so that the roof panel 10 at the time of collision is the first reinforcement 40 ) So that the roof panel 10 is deformed and broken so that it does not invade the vehicle interior. However, according to the prior art, since the roof panel 10 is supported by only one first reinforcing material 40, the reinforcement function of the roof panel 10 is not properly performed, so that the roof panel 10 in case of collision Deformation and breakage is frequently invaded into the interior of the vehicle, which causes a problem that the occupant is seriously injured.

In order to solve this problem, conventionally, the first reinforcing material 40 is installed in two or three overlapping, or one second reinforcing material of the X-shape to cross and cross the longitudinal direction (axle direction) and the transverse direction of the vehicle ( 15; 15 ') is provided in place of the first reinforcing material 40, so that the reinforcing function of the roof panel 10 is improved. However, when the two or three first stiffeners 40 are installed so as to be spaced apart from each other at predetermined intervals, the roof panel 10 is only partially supported in the lateral direction, so that the supporting function of the roof panel 10 is efficient. Problems that can not be performed. In addition, when the X-shaped second reinforcing material (15; 15 ') is installed, the support function of the roof panel 10 is efficiently performed, but when external force is applied in the lateral collision accident, the second reinforcing material (15); 15 ') is easily broken, and the impact of the transverse direction causes the pillar parts 50, 50', 60, 60 ', 70, 70', especially the center pillars 60, 60 ', to be invaded into the cabin. There was a problem that was greatly injured.

The present invention has been made to solve the above problems, the object of the present invention is to provide a reinforcing structure of the roof panel to improve the safety of the occupant by improving the support strength and strength in the transverse direction of the roof panel.

20: front header 30: rear header

40: first reinforcing material 50,50 ': front pillar

The present invention for achieving the above object, the front end surface of the roof panel is fixed to the front header attached to the vehicle body, the rear end surface of the roof panel is fixed to the rear header attached to the vehicle body, the upper side of both sides of the vehicle body On the upper ends of the front pillars, the center pillars, and the rear pillars provided oppositely, the edge portions of the roof panels corresponding to the roof pillars are fixed to each other, and the first reinforcement having a cross shape in a transverse direction at an angle of 90 degrees with the axle direction. In the reinforcement structure of the roof panel in which both ends of the first reinforcement are respectively fixed to the center pillar in a state in which the front end is placed in contact with the bottom of the intermediate position of the roof panel, the transverse direction forming an angle of 90 beams with the axle direction and the axle direction. Install a pair of X reinforcement of X type crossing each other in the direction so as to correspond to both sides of the first reinforcement, but arrange the second reinforcement to contact the bottom of the roof panel. Each end of the second reinforcing material is fixed to the front pillar, the center pillar, and the rear pillar in the pinned state, and the roof panel is supported by the first reinforcing material and the second reinforcing material.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing the present invention, the roof panel is a perspective view showing a vehicle supported by the reinforcement, according to this, the front end surface of the roof panel 10 to the front header 20 mounted to the vehicle body It is fixed, the rear end surface of the roof panel 10 is fixed to the rear header 30 attached to the vehicle body, the front pillar (50, 50 '), the center pillar (60, 60) provided opposite the upper side of both sides of the vehicle body '), The edges of the roof panels 10 corresponding to the upper ends of the rear pillars 70 and 70' are fixed. In addition, both ends of the first reinforcing material 40 in a state in which the first reinforcing material having a cross shape in the transverse direction and forming an angle of 90 degrees with the axle direction is in contact with the bottom of the intermediate position of the roof panel 10. The center pillars 60 and 60 'are respectively fixed. In addition, a pair of X-shaped second stiffeners 15 and 15 ′ intersecting each other in the axle direction and the transverse direction forming an angle of 90 beams with the axle direction are mutually intersected on both sides of the first stiffener 40. Each end of the second reinforcing material (15, 15 ') is the front pillar (50, 50') is installed so as to correspond, but the second reinforcing material (15, 15 ') is arranged to contact the bottom surface of the roof panel 10 And the center pillars 60 and 60 'and the rear pillars 70 and 70', the roof panel 10 is supported by the first reinforcement 40 and the second reinforcement 15.

As shown in FIG. 4, the X-shaped second reinforcing material 15 has a cross-sectional center to form a bent shape in a c-shape, thereby increasing rigidity while reducing the weight of the vehicle.

According to the present invention, while the supporting function of the roof panel 10 is satisfactorily maintained by the pair of second reinforcing materials 15, even when an external force is applied to the center pillars 60 and 60 'in the lateral collision, As the center pillars 60 and 60 'are supported by the first and second reinforcing materials 40 and 15 and 15', an external force impacts the entire body through these reinforcing materials 40, 15 and 15 '. Since it is dispersed, the stiffness in the transverse direction is improved.

According to the present invention as described above, one end of the first reinforcement of the --shape fixed to the center pillar while crossing in the lateral direction, and the first reinforcement is disposed at each end of the front pillar, the center pillar, the rear pillar Since the roof panel is supported by two fixed X-shaped second reinforcement materials, the support strength for preventing the roof panel from invading the vehicle in the event of a collision is greatly improved, and the center pillar portion invades the interior of the vehicle in the case of a lateral collision. The strength which prevents it from becoming is improved.

Therefore, the safety of the occupant is greatly improved.
