The invention discloses a buffer device and a vehicle. The technical problem that in the prior art, the buffering effect is poor after an automobile is collided is solved. The buffering device is installed at the end of a steering transmission shaft and comprises a first-stage buffering assembly, a second-stage buffering assembly and an installation frame which are sequentially connected in a force transmission mode, the second-stage buffering assembly comprises two buffering units, each buffering unit comprises a first support, a force transmission sliding block, a force unloading mechanism and a force transmission rod, and one end of the first support is connected with the installation frame; the force transmission sliding block is connected with the first-stage buffering assembly through a connecting arm, and the force transmission sliding block is in sliding connection with the first support. The force unloading mechanism is parallel to the mounting frame; one end of the dowel bar is hinged to the force transmission sliding block, and the other end of the dowel bar is hinged to the force unloading mechanism, so that the first support, the force unloading mechanism and the dowel bar form a triangular structure. And compared with a first-stage buffering assembly, the buffering assembly has higher buffering performance, the steering transmission shaft can be better protected, and the using effect of the steering transmission shaft after collision is improved.

    本申请公开了一种缓冲装置及车辆。以解决现有技术中汽车发生碰撞后缓冲效果不佳,的技术问题。其中缓冲装置,安装于转向传动轴的端部,包括依次传力连接的一级缓冲组件、二级缓冲组件和安装架,其中二级缓冲组件包括两个缓冲单元,其中缓冲单元包括第一支架、传力滑块、卸力机构和传力杆,其中第一支架一端与安装架连接;传力滑块通过连接臂与一级缓冲组件连接,且传力滑块与第一支架滑动连接;卸力机构与安装架平行设置;传力杆一端与传力滑块铰接,另一端与卸力机构铰接,以使第一支架、卸力机构和传力杆形成三角形结构。相较于设置一级缓冲组件,具有更强的缓冲性能,能够更好的保护转向传动轴,提高转向传动轴在碰撞后的使用效果。
