Document Type and Number:
WIPO Patent Application WO/2021/155645
Kind Code:
A1
Abstract:
A novel anti-impact device and a working method thereof. The novel anti-impact device comprises, sequentially connected: a first connector, an upper outer cylinder (15), a lower outer cylinder (12) and a second connector. The top of the lower outer cylinder (12) is sleeved within the upper outer cylinder (15) so as to be movably connected to the upper outer cylinder (15); and an aluminum honeycomb (10) and a magnetorheological buffer outer cylinder (9) are arranged inside the lower outer cylinder (12). The aluminum honeycomb (10) is arranged at the bottom of a lower end cover (11), a piston rod (5) is arranged inside the magnetorheological buffer outer cylinder (9), the top end of the piston rod (5) extends out of an upper end cover (14) and is connected to an impact head (3), and a return spring (4) is sleeved on the piston rod (5) between the impact head (3) and the upper end cover (14); and an electromagnetic coil (7) is wound around the piston rod (5), the lower part of the piston rod (5) is a damping piston (8), on which a damping hole is provided, the bottom end of the damping piston (8) is provided with a guide plate (13), and the lower part of the guide plate (13) is filled with a magnetorheological fluid. The novel anti-impact device is mounted between two carriages of a tramcar, capable of preventing, when the speed of the rear carriage is greater than that of the front carriage or the front carriage is braked, the impact of the rear carriage to buffer and achieve effective deceleration, and buffering the subsequent carriages in the event of an accident to effectively prevent the secondary injury of the accident.
