The invention provides an anti-collision beam (20) of a vehicle door, the anti-collision beam (20) is provided with a plurality of sections in the length direction of the anti-collision beam (20), and the sections comprise a middle section (21) centered in the length direction, end sections (22) located at the two opposite ends in the length direction and transition sections (23) located between the middle section (21) and the end sections (22). The intermediate section (21) has a first hardness, the end section (22) has a second hardness, the first hardness is greater than the second hardness, and the hardness of the transition section (23) is between the first hardness and the second hardness. The invention further relates to a corresponding vehicle door and a vehicle. The anti-collision beam (20) has different hardness in different sections, so that the anti-collision beam (20) has high impact resistance, small thickness, small weight and/or good connection strength.
本申请提出了一种车门的防撞梁(20),其中,所述防撞梁(20)沿其长度方向具有多个区段,所述多个区段包括沿所述长度方向居中的中间区段(21)、位于所述长度方向上的两个相反端部处的端部区段(22)和位于中间区段(21)与端部区段(22)之间的过渡区段(23),中间区段(21)具有第一硬度,端部区段(22)具有第二硬度,第一硬度大于第二硬度,过渡区段(23)的硬度在第一硬度与第二硬度之间。本申请还涉及相应的车门和车辆。通过使防撞梁(20)在不同区段具有不同的硬度,可使防撞梁(20)在具有高抗冲击能力的同时,还能具有较小的厚度、较小的重量和/或良好的连接强度。
