The lower reinforcing plate 19 has a fourth cavity 193 communicating with the third cavity 183 . The fourth cavity 193 can reduce the weight of the lower reinforcing plate 19 , reduce the weight of the lower reinforcing plate 19 and at the same time ensure the structural strength of the lower reinforcing plate 19 . The fourth cavity 193 communicates with the third cavity 183, so that the force at the shock absorber 121 is transmitted from the fourth cavity 193 to the third cavity 183, and then transmitted to the first cavity 133 by the third cavity 183 and the second cavity 143 form a closed-loop force transmission path. In some embodiments, the lower reinforcing plate 19 has a fourth cavity 193, and the fourth cavity 193 communicates with the third cavity 183, which can improve the torsional stiffness and NVH performance of the electric vehicle 10, and has a simple structure and light weight. Easy to implement.
