Reference is made to fig. 3 and 4, which show a schematic view of a reinforcement structure and a cross-sectional view of the reinforcement structure, proposed according to an embodiment of the present invention. The reinforcement structure 100 is installed within and extends through the rocker beam structure of the vehicle. In the reinforcing structure 100, a plurality of cavities, in the embodiment of fig. 3, 6 cavities, are formed, the strength of the cavity structure closer to the vehicle interior side being greater than the strength of the cavity structure closer to the vehicle exterior side, i.e., the strength of the three cavity structures on the left side being greater than the strength of the three cavity structures on the right side in fig. 4, whereby the three cavity structures on the left side resembling a Chinese character 'mu' form an energy absorption region of the reinforcing structure 100 for absorbing kinetic energy in a collision, and the three cavity structures on the right side resembling a Chinese character 'mu' form a holding region of the reinforcing structure 100 for holding the strength and collision stability of the rocker beam.

The outer geometry of the reinforcement structure 100 is configured to conform to the inner geometry of the rocker beam of the vehicle so that the left and right side interface surfaces of the reinforcement structure 100 are parallel to the vertical plane of the rocker inner panel 101. The arrangement mode of 6 cavities is three rows and two columns, the longitudinal boundary surface of the cavity except the vertical plane of the threshold beam inner plate 101 is parallel to the vertical plane of the threshold beam inner plate 101, and the transverse boundary surface of the cavity except the upper surface and the lower surface of the threshold beam inner plate 101 is perpendicular to the vertical plane of the threshold beam inner plate 101. That is, it is equivalent to adding a vertical longitudinal panel, which is parallel to the left and right sides of the rocker inner panel 101 and perpendicular to two lateral panels, and two lateral panels, which are parallel to each other, in the completely hollow reinforcement beam structure, thereby dividing the hollow reinforcement beam structure into six cavities. The upper side of the reinforcing structure 100 is connected with the upper surface of the rocker inner panel 101 through bolts, and the lower side of the reinforcing structure 100 is glued with the lower surface of the rocker inner panel 101, so that the installation stability between the rocker inner panel 101 and the reinforcing structure 100 is enhanced. As shown in fig. 4, four corners of the outer side of the reinforcing structure 100 are configured to be rounded. The reinforcing structure 100 is integrally formed of extruded aluminum, wherein the cross-sectional width of a single profile of the extruded aluminum profile constituting the left and right vertical edge interfaces of the reinforcing structure 100 may be 5 to 8 mm, and the cross-sectional width of a single profile of the remaining extruded aluminum profile may be 3.5 to 5.5 mm. The length of the reinforcing structure 100 can be 1700-1900 mm. The height and width of the reinforcing structure 100 are determined according to the size of the rocker beam inner and outer panels.

It should be understood that the number of the cavities is not limited to 6, and the boundary surfaces of the cavities can be differently shaped. Thereby additional connection mode can also be passed through with the upside and the downside of additional thereby the stability of threshold roof beam inner panel connection realization structure, for example threaded connection, joint, grafting etc.

Referring to fig. 5, which shows a schematic view of a rocker beam assembly 10 according to an embodiment of the present invention, the rocker beam assembly 10 includes a rocker outer panel 102, a rocker inner panel 101, and a reinforcement structure 100. The rocker outer panel 102 and the rocker inner panel 101 are connected to each other and form a cavity in which the reinforcement structure 100 is disposed.

Referring to fig. 6, which shows an assembly view of a threshold beam assembly according to an embodiment of the invention, the arrows in the figure indicate the direction of force transmission in a side pillar collision. The rocker beam assembly 10 overlaps the second floor cross member 200, the third floor cross member 300, and the B-pillar structure 400, thereby enhancing the bending resistance of the rocker beam structure of the vehicle body and effectively transmitting the collision force of side impact to the second floor cross member 200, the third floor cross member 300, and the B-pillar structure 400. The stronger bending resistance of the reinforcing structure 100 ensures the strength of the vehicle body sill beam structure and controls the intrusion deformation of the vehicle body sill beam structure, thereby ensuring the living space of passengers, improving the safety performance of the collision of the side pillars of the whole vehicle and effectively protecting the safety of the passengers.
