Abstract

The invention discloses a backing device for driver seat collision of a metro vehicle, and relates to the technical field of driver seats of metro vehicles. The backing device comprises a front sleeving, a shearing pin assembly and a rear sleeving. The front sleeving comprises a front square tube and a sealing vertical plate. The shearing pin assembly comprises two shearing pins and two blocking blocks. The rear sleeving comprises a rear square tube, a connecting plate, an L-shaped plate and an opening vertical plate. The backing device for driver seat collision of the metro vehicle has the beneficial effects that a driver seat is fixed on the backing device, and when collision occurs between vehicles, the backing device drives the driver seat to move back automatically for a section of distance in order to ensure the fact that an enough safe distance is left between the driver seat and a driver console in a collision accident, so that the survival probability of a driver in the vehicle collision accident is improved, and requirements of the ASME RT-2-2014 standard of the America are met.

Description

technical field [0001] The invention relates to the technical field of a subway vehicle driver's seat, in particular to a collision retreat device for a subway vehicle driver's seat. Background technique [0002] At present, the driver's seats of domestic and foreign subway vehicles are all fixed on the vehicle chassis floor with bolts. When a vehicle collision occurs, the structure in front of the driver's seat, especially the driver's console, is squeezed and retreats, while the driver's seat Since it is installed on the floor, the position basically does not move. Therefore, when a collision accident occurs, the living space between the driver's seat and the driver's console will be compressed. When the accident is minor, it is difficult for the driver to escape from the narrow space and cannot get timely assistance; when the accident is serious, the driver will be injured or killed due to extrusion. [0003] According to the requirements of the American ASME RT-2-2014 ...
