The invention provides an energy-absorbing braking device and an energy-absorbing braking method, and the energy-absorbing braking device comprises an anti-collision beam which is restrained by a limiting assembly and is kept parallel to a cross beam of a vehicle body; two sets of two-connecting-rod assemblies are arranged on the two sides of the limiting assembly respectively, and the two ends of each two-connecting-rod assembly are pivoted to the anti-collision beam and the vehicle body cross beam respectively; and at least one tension spring which is arranged between the anti-collision beam and the vehicle body cross beam in parallel, the two ends of the tension spring are connected to the hinged joints of the two-connecting-rod assembly respectively, and the tension spring provides reset tension for restraining the hinged joints from expanding outwards to the two sides. A long-distance energy absorption stroke can be provided by fully utilizing the width of the vehicle body, the thickness of the energy absorption device is greatly reduced, the occupation of the internal space of the vehicle is reduced, and the driving flexibility of the vehicle is enhanced.

    本发明提供了吸能制动装置以及吸能制动方法,吸能制动装置包括了:一防撞梁,受限位组件约束,保持与车体横梁平行;两套二连杆组件,分别设置于限位组件的两侧,二连杆组件的两端分别枢接于防撞梁、车体横梁;以及至少一拉簧,拉簧平行设置于防撞梁与车体横梁之间,拉簧的两端分别连接于二连杆组件的铰接节点,拉簧提供约束铰接节点向两侧外扩的复位拉力。本发明能够充分利用车身宽度提供长距离的吸能行程,大大缩小了吸能装置的厚度,减少了对车辆内部空间的占用,增强了车辆行驶的灵活性。
