Connection transition plate for vehicle

Technical Field

The application relates to the field of auxiliary accessories of railway vehicles, in particular to a connecting transition plate for a vehicle.

Background

In daily life, when a railway vehicle such as a train, a motor car and a high-speed rail stops at a station, a gap with a certain width exists between a car door and the station, so that passengers need to cross the gap when getting on or off the car; however, for the disabled person who takes the wheelchair and the old person who is inconvenient to move, the disabled person cannot cross the gap, and the passenger may carry a large piece of luggage and cannot lift, so that a transition plate is paved between the vehicle door and the platform by people, and the convenience of getting on and off the vehicle by the disabled person who is inconvenient to move and the passenger who carries the large piece of luggage is improved.

However, when the common transition plate is used, a lot of problems usually exist, along with development of technology, a person skilled in the relevant field performs a lot of optimization on the vehicle connection transition plate, for more accurate comparison, for example, a vehicle transition plate disclosed in chinese patent publication No. CN217477286U includes an outer skin, an inner skin and a core material disposed between the outer skin and the inner skin, the core material includes a plurality of longitudinal ribs, the plurality of longitudinal ribs are arranged along a first direction, the longitudinal ribs are in a bending structure, and include a first folded edge and a second folded edge, and an included angle is formed between the first folded edge and the second folded edge; the transverse ribs are arranged along the second direction, the second direction is perpendicular to the first direction, two ends of the longitudinal rib in the length direction are respectively provided with two transverse ribs, and one of the transverse ribs is provided with a mounting hole.

When the device works, the transition between the platform height and the vehicle body height is realized by setting the longitudinal ribs as a bending structure, and the mounting holes are arranged on the transverse ribs on one side of the longitudinal ribs to mount the hinge structure, so that the lifting and the lowering of the transition plate are realized; when a person passes through the transition plate, in order to prevent falling, anti-slip patterns are generally required to be arranged on the upper surface of the transition plate, so that an anti-slip effect is achieved.

However, the above-mentioned vehicular transition plate has some disadvantages in the practical use process:

1. the transition plate is of a bending structure, and the upper end of the transition plate is an inclined surface, so that passengers with inconvenient actions can get on or off the wheelchair, and the transition plate does not have anti-slip measures for the wheelchair, so that the phenomena of deflection of the travelling direction of the wheelchair, slipping of wheels and the like easily occur when the passengers get on or off the wheelchair, and the passengers are easy to drop from the wheelchair.

2. And because the transition plate can not be fixed after being placed, the transition plate is easy to move after being stressed, when a passenger using the crutch or a passenger taking a wheelchair gets on or off, the transition plate can be displaced under the action of gravity of the crutch or the wheelchair, so that the passenger is easy to fall down, and therefore, a great potential safety hazard exists, and the lower end of the crutch is easy to slip due to the inclined surface at the upper end of the transition plate, so that the passenger is easy to fall down.

3. In addition, although the purpose of transition can be played between automobile body and platform, nevertheless need the crew to take the cab apron and place in the door department of automobile body, consequently the complex operation, and to the inconvenient passenger of action, need the crew to place the cab apron and accomplish the back and just can get on or off the bus to can't ensure the passenger in time get on or off the bus, and then cause the jam of other passengers on or off the bus easily.
