The invention relates to the technical field of seat sliding rails, in particular to a seat sliding rail with a buffering mechanism, which comprises a first sliding rail, a sliding rod and a triggering mechanism, the sliding rod is matched with the first sliding rail, the inner wall of the first sliding rail is provided with uniformly distributed clamping grooves, the sliding rod is provided with an elastic rod, and the elastic rod is connected with the triggering mechanism. Clamping teeth matched with the clamping grooves are installed at the lower end of the elastic rod, when the elastic rod is completely compressed, the clamping teeth are separated from the clamping grooves, at the moment, the sliding rod can slide along the first sliding rail, in the device, after collision occurs or an automobile is suddenly braked, the third electromagnet is switched on, the magnetorheological fluid is turned into a solid state under the action of magnetic force, and the friction block cannot move; the friction block forms a circle of speed reduction block in the second sliding rail, the sliding block can move in the second sliding rail, the friction block decelerates the sliding block, speed reduction of the sliding rod is achieved, at the moment, when the seat is subjected to external force, the seat can move in a small range, a passenger is buffered, and the safety of the seat is improved.

    本发明涉及座椅滑轨技术领域,尤其涉及一种具有缓冲机构的座椅滑轨,包括第一滑轨、滑杆和触发机构,所述滑杆和第一滑轨相适配,第一滑轨的内壁上设置有均匀分布的卡槽,所述滑杆安装有弹性杆,所述弹性杆的下端安装有与卡槽相适配的卡齿,当弹性杆被完全压缩时,卡齿与卡槽相分离,此时滑杆可以沿第一滑轨滑动,本装置中,当发生碰撞或汽车发生急刹车后,第三电磁铁被接通,磁流变液在磁力作用下,变成固态状,摩擦块无法移动,摩擦块在第二滑轨内部形成一圈圈减速块,滑块可以在第二滑轨内移动,且摩擦块对滑块进行减速,实现滑杆的减速,此时座椅在受到外力作用时,可以小幅度的运动,对乘坐人进行缓冲,提高了座椅的安全性。
