As shown in fig. 7, an air inlet is disposed on the surface of the spherical elastic sheet 27; the surface of the spherical elastic sheet 27 is provided with an air outlet 33 at a position close to the air inlet; the surface of the safety plate 21 is fixedly connected with elastic blocks 29 which are uniformly arranged; an air bag 30 is fixedly connected between two adjacent elastic blocks 29; the surface of the elastic block 29 is fixedly connected with a pressing block; a first one-way pipe 31 is connected between the air bag 30 and the air inlet hole of the spherical elastic sheet 27, and the air bag 30 is communicated with the outside atmosphere in a one-way mode; the during operation, through setting up elasticity piece 29, when wheelchair or passenger's surface downstream at cab apron body 2, under the effect of gravity, pedestrian's foot or wheel can extrude elasticity piece 29, even elasticity piece 29 can play anti-skidding effect, receive extruded elasticity piece 29 simultaneously and warp, two adjacent elasticity pieces 29 can extrude gasbag 30, make the inside of the gaseous a large amount of one-way leading-in spherical shell fragment 27 of gasbag 30 inside, spherical shell fragment 27 inflation, and then if the wheelchair has appeared when swift current car problem, a large amount of gasbags 30 can receive the extrusion in the short time, and the gaseous a large amount of spherical shell fragment 27 that gets into of the inside, the spherical shell fragment 27 of inflation state improves the effect that blocks the wheelchair, guarantee the passenger of taking the wheelchair at the security of the in-process of getting off the bus.

A drain hole is formed in the surface of the safety plate 21 at the position of the air bag 30; the air outlet hole 33 of the spherical elastic sheet 27 is fixedly connected with a second one-way pipe 32; the side surfaces of the elastic blocks 29 are provided with air outlet holes 33, and the air outlet holes 33 are communicated with the second one-way pipe 32; during operation, during sleet weather, the access & exit position of train drenches water easily, and these water flows down along with cab apron body 2, perhaps glues the surface of cab apron body 2 through pedestrian's foot, has increased cab apron body 2's slippery problem, can discharge the water on cab apron body 2 surface fast through the wash port, and when wheel or passenger's foot extrusion spherical shell fragment 27 simultaneously, the inside gas of spherical shell fragment 27 can one-wayly be led out through venthole 33, realizes giving vent to anger dry to the elastic block 29 surface.

According to the working principle, when the cab apron body 2 needs to be used, firstly, a power supply is switched on, a switch is started, the electric sliding block 5 slides downwards in the second guide rail 4, meanwhile, the mounting plate 1 can be pushed manually to adjust the position, the mounting plate 1 can synchronously drive the cab apron body 2 to adjust the position, so that the cab apron body 2 corresponds to the train inlet and outlet, at the moment, the electric guide block can drive the gear 7 to move downwards, the gear 7 and the toothed plate 6 are meshed and connected, the gear 7 synchronously rotates in the downward movement process, the gear 7 further drives the cab apron body 2 to rotate, and finally the cab apron body 2 is loaded between a train and a platform; in the process that passengers wait for taking a bus at a platform, in order to facilitate rapid position movement among a large number of people at the platform, a large number of people can enter a safety defense line, because the platform is open, the train rails are far lower than the platform, and safety accidents are easily caused by the behavior of the passengers, through arranging the infrared probe 8, the infrared probe 8 can constantly detect the condition inside the safety defense line, and if the inside enters the passengers, an alarm can be automatically given in time to remind the passengers to rapidly leave a warning area; because the platform serves different trains, and the height difference between different trains and the platform is different, by arranging the rotating rod 11, when the gear 7 drives the cab apron body 2 to rotate, if one end of the cab apron body 2 is already carried on the train, but the other end of the cab apron body is not yet contacted with the platform, the rotating rod 11 and the gear 7 can rotate mutually and compress the first spring 12, so that the electric slide block 5 can continuously move downwards at the moment to drive the cab apron body 2 to be completely contacted with the platform, and the two ends of the cab apron body 2 can be ensured to be fully contacted with the surfaces of corresponding positions; when the electric sliding block 5 slides to the bottom position of the second guide rail 4, the second electric sliding block 5 can extrude the telescopic bag 13, so that the gas in the telescopic bag 13 enters the guide groove, the limiting guide block 14 in the guide groove is ejected out, and the limiting guide block 14 can be inserted into the limiting groove at the corresponding position, at the moment, the position limitation of the safety plate 21 and the cab apron body 2 can be realized, and when a passenger gets on or off the train through the cab apron body 2, the cab apron body 2 cannot be displaced along the direction of the train rail due to large acting force; by arranging the guide plate 16, when the cab apron body 2 is carried on a platform and a train, because the height difference between the platform and different trains is different, the connection effect of the end surface of the cab apron body 2 is poor, and the wheelchair wheel is inconvenient to move at the joint position of the end part of the cab apron body 2, so that the guide plate 16 can be extruded by the elastic sheet 17 and the guide plate 16 through the elastic sheet 17 and the guide plate 16, the guide plate 16 rotates at the end part of the cab apron body 2, and the guide plate 16 can play a better guiding role; by arranging the movable plate 18, when the wheelchair moves obliquely upwards on the surface of the cab apron body 2, the electric push rod 19 is controlled to extend, the electric push rod 19 can drive the movable plate 18 to move, the movable plate 18 can drive the ejector rod 20 to move, the ejector rod 20 can extrude the safety plate 21, so that the safety plate 21 rotates and is led out of the accommodating groove, at the moment, when the wheelchair moves upwards, the safety plate 21 is extruded and extruded, the ejector rod 20 and the telescopic spring are extruded by the safety plate 21, the safety plate 21 automatically retracts inwards to correspond to the accommodating groove, and if the wheelchair has a backward sliding problem, the safety plate 21 can be pressed against wheels of the wheelchair to play a safety protection role; by arranging the convex block 22, when the safety plate 21 rotates and is internally accommodated in the accommodating groove, the bottom of the safety plate 21 extrudes the convex block 22 and is extruded by the convex block 22, the push plate 23 moves upwards and drives the anti-skid block 24 to move, and the ejected anti-skid block 24 plays an anti-skid role when the wheelchair or a passenger moves downwards; by arranging the swinging block 25 at the top of the anti-skid block 24, when the wheelchair moves downwards, the wheelchair can easily and quickly move downwards due to the downward inertia effect and extrude the swinging block 25, if the downward speed is too high, the safety problem can be caused, the swinging of the swinging block 25 extrudes the elastic sheet 26 to play a role in buffering, the safety of downward movement of pedestrians and the wheelchair is ensured, and meanwhile, the buffering effect is further improved through the elastic effect of the spherical elastic sheet 27; by arranging the elastic blocks 29, when a wheelchair or a passenger moves downwards on the surface of the cab apron body 2, under the action of gravity, feet or wheels of the pedestrian can extrude the elastic blocks 29, the uniform elastic blocks 29 can play a role of skid resistance, and meanwhile, the extruded elastic blocks 29 deform, the air bags 30 can be extruded by the two adjacent elastic blocks 29, so that a large amount of air in the air bags 30 can be led into the spherical elastic pieces 27 in one way, the spherical elastic pieces 27 expand, and further, if the wheelchair has the problem of rapid sliding, a large amount of air bags 30 can be extruded in a short time, and a large amount of air in the air bags enters the spherical elastic pieces 27, the spherical elastic pieces 27 in an expanded state improve the blocking effect on the wheelchair, and the safety of the passenger taking the wheelchair in the process of getting off the vehicle is ensured; in rainy and snowy weather, water is easily sprayed at the positions of the entrances and exits of the trains, the water flows downwards along with the cab apron body 2, or the water is adhered to the surface of the cab apron body 2 through the feet of pedestrians, so that the problem of wet and slippery of the cab apron body 2 is solved, the water on the surface of the cab apron body 2 can be quickly discharged through the drain holes, meanwhile, when the wheels or the feet of passengers extrude the spherical elastic pieces 27, the gas in the spherical elastic pieces 27 can be guided out through the air outlet holes 33 in one way, and the air outlet drying on the surface of the elastic blocks 29 is realized.
