The invention provides a vehicle body plate, a vehicle door and a vehicle, the vehicle body plate comprises an outer plate, an inner plate and a negative Poisson's ratio structure, and the negative Poisson's ratio structure comprises at least two cell element layers connected between the outer plate and the inner plate in a stacked mode; each cell element layer comprises a plurality of basic cell elements which are connected in sequence; and when the vehicle body plate is subjected to a load perpendicular to the vehicle body plate, the outer wall of each basic cell element shrinks towards the center of the basic cell element. According to the vehicle body plate, the vibration suppression and energy absorption level is improved, meanwhile, the light weight level of the vehicle body plate is improved, and the vibration suppression and energy absorption performance of the vehicle body plate and the light weight requirement of the vehicle body plate can be considered.

    本发明提供一种车身板件、车门及车辆,包括外板、内板以及负泊松比结构,所述负泊松比结构包括层叠连接在所述外板和内板之间的至少两个胞元层;每一个所述胞元层均包括顺次连接的多个基础胞元;所述车身板件受到垂直于所述车身板件的载荷时,每个所述基础胞元的外壁向所述基础胞元的中心收缩。本发明车身板件在提升了抑振吸能水平的同时,还提升了车身板件的轻量化水平,可以兼顾车身板件抑振吸能性能和车身板件轻量化需求。
