The reinforcement beam 42 is disposed in the accommodating cavity 41, and the reinforcement beam 42 is fixedly disposed on the threshold beam 40, as some alternative embodiments of the present application, the reinforcement beam 42 may extend along a length direction (i.e., an X direction shown in fig. 1) of the vehicle, and the threshold beam 40 may extend along the length direction (i.e., the X direction shown in fig. 1) of the vehicle. In the first direction of the rocker beam 40, i.e., in the width direction of the vehicle (i.e., in the Y direction shown in fig. 1), the reinforcement beam 42 is disposed spaced apart from the inner side wall 411 of the accommodation chamber 41, specifically, the reinforcement beam 42 is disposed spaced apart from the inner wall of the rocker inner panel 43, and the inner wall of the rocker inner panel 43 can be understood as the wall of the rocker inner panel 43 facing the accommodation chamber 41.

When the vehicle is subjected to a side collision, since the reinforcement beam 42 is spaced from the inner side wall 411 of the accommodating chamber 41, if the collision force is small, the spacing between the reinforcement beam 42 and the inner side wall 411 of the accommodating chamber 41 can fully absorb the intrusion amount of the reinforcement beam 42, so that intrusion of the reinforcement beam 42 toward the inside of the vehicle can be avoided, and transmission of collision energy into the vehicle and the battery pack 5 by the reinforcement beam 42 can be avoided.

In some embodiments of the present utility model, as shown in fig. 4 to 6, the reinforcement beam 42 may have a plurality of buffer chambers 423, and the plurality of buffer chambers 423 may be sequentially arranged in a first direction, i.e., in a width direction of the vehicle (i.e., in a Y direction shown in fig. 5). The side collision performance of the reinforcement beam 42 can be effectively improved by the arrangement, so that the side collision performance of the vehicle is improved, and the reinforcement beam 42 is improved in manufacturing difficulty and efficiency by constructing the plurality of buffer cavities 423 of the reinforcement beam 42 in a mode of sequentially arranging the buffer cavities along the first direction.

As some alternative embodiments of the present application, as shown in fig. 4-6, the reinforcement beam 42 may define a first cavity 424, and a plurality of partition plates 425 may be disposed in the first cavity 424, and the plurality of partition plates 425 may be sequentially spaced apart in a first direction to divide the first cavity 424 into a plurality of buffer cavities 423.
