The invention relates to the technical field of vehicles, and discloses an engine hood and a vehicle. The hood includes an outer plate and an inner plate. The inner plate is arranged on the inner side of the outer plate, the inner plate comprises an inner plate frame and three connecting ribs, the inner plate frame is connected with the outer plate, the inner plate frame is provided with a central hollowed-out part, the central hollowed-out part extends in the left-right direction so that the inner plate frame can be annular, the cross section of each connecting rib can be in a flat plate shape, and the three connecting ribs are sequentially arranged on the central hollowed-out part at intervals from left to right; and two ends of the connecting rib are respectively connected with the front edge and the rear edge of the central hollow part. When observed in the top view direction of the inner plate, the ratio of the area of the central hollow part to the total area of the inner plate is larger than 50%. Through the central hollow part and the connecting ribs, the rigidity of the middle area of the engine hood is reduced, the collision probability of the human body and the entity part of the inner plate is reduced, and the impact force on pedestrians in the collision process is reduced. And the torsion resistance of the inner plate frame is improved, the local strength of the inner plate is prevented from being too high, and damage to pedestrians during collision is reduced.
本发明涉及车辆技术领域,公开了一种发动机罩及车辆。发动机罩包括外板和内板。内板设于外板的内侧,内板包括内板框及三根连接筋,内板框与外板相连,内板框上开设有中心镂空部,中心镂空部沿左右方向延伸,以使内板框呈环状,连接筋的横截面呈平板状,且三根连接筋从左至右依次间隔设于中心镂空部,连接筋的两端分别与中心镂空部的前边沿、后边沿连接。沿内板的俯视图方向观察,中心镂空部的面积与内板的总面积的比值大于50%。通过中心镂空部和连接筋,降低发动机罩的中部区域的刚度,降低人体与内板实体部分的碰撞概率,减小在碰撞过程中对行人的冲击力。且提高了内板框的抗扭能力,并且避免内板的局部强度过大,减小碰撞时对行人造成的伤害。
