The invention discloses an anti-getting-into protection device for the rear of a truck. The anti-getting-into protection device comprises a first anti-collision cross beam and a second anti-collisioncross beam which are located below the rear of a frame, the first anti-collision cross beam is located behind the second anti-collision cross beam, the two ends of the first anti-collision cross beamare fixedly connected to the lower end of a first connecting rod, and the upper end of the first connecting rod is hinged to the rear end of a longitudinal beam of the frame; the two ends of the second anti-collision cross beam are fixedly connected to the lower end of a second connecting rod, and the upper end of the second connecting rod is hinged to the longitudinal beam of the frame; sliding blocks are connected between a hinge part of the longitudinal beam of the frame and the first connecting rod and a hinge part of the longitudinal beam of the frame and the second connecting rod in a sliding manner, the sliding blocks are hinged to one end of a third connecting rod and that of a fourth connecting rod respectively, the other end of the third connecting rod is hinged to the lower partof the first connecting rod, and the other end of the fourth connecting rod is hinged to the middle of the second connecting rod; and a buffer component for limiting the displacement of the sliding blocks is fixed on the longitudinal beam of the frame. The anti-getting-into protection device is simple in structure, low in cost, and high in protection ability, and can better solve the problem thatcars get into trucks in rear-end collision accidents, thereby reducing traffic accident mortality.

    本发明公开了一种卡车后部防钻保护装置,包括位于车架后部下方的第一防撞横梁和第二防撞横梁,第一防撞横梁位于第二防撞横梁后方,第一防撞横梁两端分别与第一连杆下端固定连接,第一连杆上端与车架纵梁后端铰接;第二防撞横梁两端分别与第二连杆下端固定连接,第二连杆上端与车架纵梁铰接;车架纵梁在与第一连杆铰接处和与第二连杆铰接处之间滑动连接有滑块,滑块分别与第三连杆和第四连杆的一端铰接,第三连杆另一端与第一连杆下部铰接,第四连杆另一端与第二连杆中部铰接;车架纵梁上固定有用于限制滑块位移的缓冲组件。其结构简单,成本低廉,防护能力强,能够较好地解决追尾事故中小汽车的钻卡问题,从而降低交通事故死亡率。
