The invention relates to an energy absorption component for a bumper assembly, the bumper assembly and a vehicle. The energy absorbing component (2) is configured to be arranged behind a bumper body (1) of a bumper assembly and is provided with a retaining channel (21) suitable for retaining a flexible pressure pipe (3), so that the pressure pipe (3) deforms when the bumper body (1) is impacted, the retaining channel (21) comprises a middle section (211) extending in the transverse direction of the energy absorption component (2) and a bent section (212) extending out of the end of the middle section, a plurality of notches are formed in the wall of the bent section (212), and the multiple notches are arranged on the two sides of the pressure pipe (3) alternately in the extending direction of the retaining channel (21). According to the energy absorption component, the deformation sensitivity of the pressure pipe arranged in the energy absorption component can be basically kept consistent along the whole length of the pressure pipe, so that the air pressure threshold value for triggering the engine cover to automatically bounce can be accurately calibrated.

    本发明涉及用于保险杠总成的吸能部件、保险杠总成及车辆。所述吸能部件(2)配置成布置于保险杠总成的保险杠本体(1)后方并设有适于保持柔性压力管(3)的保持通道(21),以在保险杠本体(1)受到撞击时使压力管(3)发生变形,其中,所述保持通道(21)包括沿着吸能部件(2)的横向方向延伸的中间区段(211)和从中间区段的端部延伸出的弯曲区段(212),所述弯曲区段(212)的壁设有多个缺口,所述多个缺口配置成沿着所述保持通道(21)的延伸方向交替地布置于压力管(3)两侧。根据本发明的吸能部件有利于使布置于其中的压力管的变形敏感度沿该压力管的整个长度保持基本一致,以使得触发发动机罩自动弹起的气压阈值能够被精确标定。
