Abstract

The invention provides an apron board locking failure protection device and a bullet train, wherein the apron board locking failure protection device comprises a first fixed piece which is used for being fixedly connected with a bottom frame of a vehicle and is provided with a first hooking piece, and a second fixed piece which is used for being fixedly connected with the upper end of an apron board and is provided with a second hooking piece; the first hooking piece and the second hooking piece are arranged in an opposite way and can be fixed in a hooking way; and the first hooking piece is hooked with the second hooking piece, so that the apron board can be prevented from getting away from the bottom frame of the vehicle, and the vehicle is ensured to run more safely. In addition, a curb chain is not used by the apron board locking failure protection device, so that the apron board is guaranteed not to be damaged.

Description

technical field [0001] The invention relates to vehicle safety technology, in particular to a skirt plate locking failure protection device and a motor vehicle. Background technique [0002] see Figure 1a , Figure 1b and Figure 1c , in order to protect the equipment hoisted at the lower part of the carriage, the high-speed EMU will add a protective plate under both sides of the carriage 1, which is called the skirt plate 2. The upper end of the skirt plate 2 is threadedly connected with the vehicle underframe 3, and the lower end is fixed on the crossbeam 4, which is suspended below the underframe. During the high-speed driving of the vehicle and when meeting vehicles, passing through caves and bridges and other environments, the apron 2 will generate strong positive and negative pressures and strong vibrations due to airflow changes, which may cause the upper end of the apron 2 to collide with the bottom of the vehicle. The threaded connection between the frames 3 fai...
