The invention discloses a small-offset collision active protection threshold device which comprises an original threshold, the original threshold comprises an inner plate, an outer plate and a cavity formed by the inner plate and the outer plate, and an active protection threshold is arranged in the cavity between the inner plate and the outer plate of the original threshold; when small offset collision occurs, the front end of the active protection threshold extends out of the original threshold and abuts against the tire. The active protection threshold is arranged at the front end of an existing threshold and shielded by the wheel cover plate, in the vehicle running process, space conflicts do not exist between the active protection threshold and other surrounding parts, the active protection threshold is triggered only when collision occurs, and therefore the active protection threshold extends forwards to make contact with tires in advance, and a fulcrum is provided for a vehicle body, the vehicle rotates around the threshold, so that the threshold is prevented from colliding with the front of the passenger compartment; therefore, a plurality of reinforcing plates do not need to be additionally arranged for the upper longitudinal beam, the column A and the threshold, and the active protection threshold is not increased too much in weight, so that the collision with the energy-saving and environment-friendly development concept of the automobile is avoided.
本发明公开了一种小偏置碰撞主动防护门槛装置,包括原始门槛,原始门槛包括内外板以及由内外板组成的空腔,原始门槛内外板之间的空腔内设有主动防护门槛;当小偏置碰撞发生时,主动防护门槛的前端从原始门槛内伸出并顶住轮胎。本发明所提供的主动防护门槛布置在现有门槛前端,被轮罩板所遮挡,车辆行驶过程中,主动防护门槛与周围其他部件的布置不存在空间方面的冲突,仅在碰撞发生时被触发,从而向前延伸,提前与轮胎发生接触,从而为车身提供支点,使车辆绕其旋转,避免刚性壁障与乘员舱正面碰撞,因而无需针对上纵梁、A柱及门槛增加诸多加强板,且主动防护门槛的增加不会增加过多重量,这样就不会与汽车节能环保开发理念冲突。
