The present invention provides a reinforcement member inside the side end structure for the purpose of protecting the occupant from the impact caused by the vehicle overturning or an object falling from the top, so that the indoor inflow of the vehicle can be significantly reduced. It relates to a reinforcement structure.

In general, when a vehicle is rolled over or an object falls naturally from the top of the roof panel, stress concentration occurs at the junction of the roofside rail, which causes severe deformation, which causes the roofside rail and the junction to be indoors. As the amount of inflow increases, it can be seen that the degree of injury to the upper body during injury of the occupant is greatly increased.

2 is a conventional side-end structure, in which the inner and outer panels 10 and 20 of the groove-shaped portion constituting the roofside rail are connected to each other to form one space part sealed therein, and the upper connection thereof. The side top end structure of the vehicle body in which the graded horizontal part of the roof panel 30 was integrally integrated in the part is shown.

This conventional side-end structure has been shown to be very vulnerable to impacts from the top of the vehicle body, and thus there is an urgent need for reinforcing its own support stiffness for this area.

Accordingly, the present invention devised in view of such a point provides a groove-shaped reinforcement panel between the roofside rail and the roof panel connected to the roof side rail, and uses the self-supporting rigidity thereof to make the most impact of the vehicle. It is an object of the present invention to provide a side reinforcement structure of the vehicle body that allows the absorption of the vehicle body to be suppressed to the extent that the side vehicle end of the vehicle body flows into the room.

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

The present invention is a side upper end of the vehicle body consisting of the inner and outer panels 10, 20 and the roof panel 30 which is integrally connected and fixed to the upper joint of these 10, 20 to have a closed space portion. In the structure, both ends of each of the panels 20 and 30 are disposed at the bottom of the junction between the outer panel 20 and the roof panel 30 while the reinforcement panel 40 is disposed to wrap the junction at regular intervals. It is fused and fixed, and the inner end of the inner panel 10 is fixed while overlapping the outer side wall of the groove bent portion of the reinforcement panel 40, and the space portion of the inner and outer panels 10, 20 and It is characterized by consisting of a structure provided with a separate buffer space portion in the neighbor.

In particular, both ends of the reinforcing panel 40 is characterized in that the semi-circular glove 41 is formed to include a sealer therein facing downward.

If this is described in more detail as follows.

3 is a cross-sectional perspective view showing a side reinforcement structure of the vehicle body according to the present invention, wherein reference numeral 20 denotes an outer panel formed in a groove shape in which a central portion protrudes upward, and 30 denotes an inner panel of the outer panel. Represents a roof panel that is connected.

The reinforcement panel 40 of the present invention is a strip-shaped panel having a length much longer than a width, and is disposed over the entire length of the side top end structure of the vehicle body, and both sides thereof are provided on the outer panel 20 and the roof panel 30. One side by one connection, while strengthening the binding between the panels 20, 30 will complement its own support stiffness.

The reinforcement panel 40 has an overall cross-sectional shape formed into a recessed portion, and the wing portion is formed at a predetermined angle so as to face in the outward direction at the ends of both side walls constituting the recessed portion.

In particular, a glove 41 having a semicircular cross section in the longitudinal direction is formed in the gradient horizontal portion of the reinforcing member 40, that is, the wing portion, and the members 40 are formed on the respective panels 20, 30. Prior to installation on the joint 41, the sealer can be used by applying it here.

The reinforcement panel 40 formed as described above is fusion-fixed to the upper side of the groove-shaped bottom surface of the outer panel 20 and the inner side of the outer horizontal portion of the roof panel by using each of the gradient-formed wings, and the panel 20. ), (30) to form a space together with the junction of the connection, it is possible to enhance the self-support stiffness of the place while complementing the connection structure of the junction. At this time, the reinforcement panel 40 is fixedly arranged in a form surrounding the bottom of the joint portion of each panel 20,30.

In addition, the inner panel 10 is formed in a groove-like overall cross-section, the outer end of the gradient is connected to the bottom end of the outer panel, the other end, for example, the inner end is vertically upwards Extending is formed in a structure coupled to one side of the reinforcing member 40.

That is, the vertically extending end portion of the inner panel 10 is fusion-bonded while overlapping the outer side wall surface of the recessed portion of the reinforcing member 40, so that the two space portions inwardly and outwardly with the junction part therebetween. It can be formed in a state arranged in succession.

Therefore, when the vehicle is overturned or when an object is dropped and the impact is transmitted to the upper part of the roof panel 30 or the upper part of the roof side rail, the inner panel 10, the outer panel 20, and the roof panel at this time. 30 is able to reduce the impact most of the two times while being sequentially deformed by using the space portion formed in a linkage structure with the reinforcing member 40, thereby significantly reducing the degree of inflow of the side upper end of the vehicle body into the room. It becomes possible.

As described above, the present invention installs a reinforcement panel inside the roofside rail, thereby effectively absorbing shock, thereby minimizing the indoor inflow of the roofside rail due to objects and falling from the vehicle overturning or falling from the top. By doing so, there is an advantage that can maximize the safety of the occupants.
