Figure 1 As shown, the fully automated driving type A vehicle electric emergency safety device provided in this embodiment includes: a fully open door 1, an evacuation ramp 2, vehicle lights 3, and a door opening and retraction mechanism 4. The top of the fully open door 1 is hinged to the top crossbeam of the vehicle body, which facilitates the upward opening and downward closing of the fully open door 1. At the same time, the evacuation ramp 2 is set on the vehicle body floor, so that when the evacuation ramp 2 is unfolded and extended to the track, passengers in the carriage can smoothly evacuate through the evacuation ramp 2. Meanwhile, vehicle lights 3 are set on the outer side of the lower part of the fully open door 1, providing lighting conditions for normal driving and evacuation.

[0028] Specifically, Figure 2 This is a structural diagram of a door opening and retraction mechanism according to a preferred embodiment of the present invention. Figure 1 and Figure 2As shown, the door leaf opening and recovery mechanism 4 is arranged on the vehicle body floor and beside the evacuation ramp 2, avoiding the interference of the door leaf opening and recovery mechanism 4 to the evacuation ramp 2 and the evacuation of people. At this time, the door leaf opening and recovery mechanism 4 comprises a support 41, a supporting rod 42, an electric telescopic device 43 and a pull rope 44. The support 41 is vertically arranged on the vehicle body floor, ensuring the stable arrangement of the support 41 on the vehicle body floor. One end of the supporting rod 42 is hingedly connected to the upper end of the support 41, so that the supporting rod 42 can swing on the support 41. The other end of the supporting rod 42 extends towards the side of the full-open door leaf 1. When the supporting rod 42 swings on the support 41, the end of the supporting rod 42 towards the full-open door leaf 1 will contact and push the full-open door leaf 1 to open, or move away from the full-open door leaf 1 to realize the recovery of the supporting rod 42. One end of the electric telescopic device 43 is hingedly connected to the lower end of the support 41, and the other end of the electric telescopic device 43 is hingedly connected to the middle part of the supporting rod 42. When the electric telescopic device 43 operates, it can provide power for the swinging of the supporting rod 42 on the support 41, and the structure design is more reasonable. Preferably, the electric telescopic device 43 is an electric push rod, which is simple in structure and convenient to control. Meanwhile, one end of the pull rope 44 is connected to the support 41, and the other end of the pull rope 44 is connected to the bottom of the full-open door leaf 1. When the full-open door leaf 1 is turned up to open, if the operator wants to turn down the full-open door leaf 1 to close, the operator only needs to pull the pull rope 44 to drive the full-open door leaf 1 to turn down, which is more convenient to operate. It should be pointed out that the one end of the supporting rod 42 hingedly connected to the support 41 is fixedly sleeved with a ratchet wheel. A manual operating rod is also rotatably arranged on the support 41 and sleeved with the ratchet wheel. The manual operating rod is provided with a pawl matched with the ratchet wheel. When the operator repeatedly swings the manual operating rod up and down, the pawl can drive the ratchet wheel to rotate, and the deflection of the supporting rod 42 is also realized, so as to manually drive the supporting rod 42 and meet the manual opening requirement. In the case of power failure, the manual opening can still be realized, which is safer and more reliable.

In addition, the rack 33 is slidably arranged in the full opening door leaf 1 along the height direction of the full opening door leaf 1, i.e. the rack 33 is arranged perpendicular to the top wall of the vehicle lamp mounting hole 111, so that the arrangement plane of the rack 33 is perpendicular to the turning over shaft of the turnover part, thereby providing conditions for the subsequent turning over of the turnover part 31 driven by the rack 33. At the same time, the half gear 35 is fixedly arranged on the turnover plate, and the intermediate gear 34 is rotatably arranged on the full opening door leaf 1 and located between the rack 33 and the half gear 35 and engaged with both of them, i.e. when the rack 33 slides from the lower part of the full opening door leaf 1 to the upper part, the rack 33 drives the intermediate gear 34 to rotate, at the same time, the intermediate gear 34 drives the half gear 35 to rotate towards the outside of the full opening door leaf 1, thereby making the turnover part 31 turn over towards the inside of the full opening door leaf 1. At this time, only the full opening door leaf 1 needs to be kept in the turned over state, and the lower part of the vehicle lamp 3 can be turned over from the vehicle lamp mounting hole 111, thereby meeting the use requirement of being inclined to illuminate forward of the vehicle, thereby illuminating the space in front of the vehicle, and the light will not be blocked by the full opening door leaf 1 itself, the illumination effect is better, which is beneficial for the passengers to obtain the external environment information in front of the vehicle, beneficial for the evacuation and improving the evacuation safety. In addition, one end of the trigger rope 32 is connected to the rack 33, and the other end of the trigger rope 32 is extended to the upper end of the full opening door leaf 1 and then passes out from the side of the full opening door leaf 1 close to the vehicle body, at the same time, the end of the trigger rope 32 passing out to the outside of the full opening door leaf 1 is connected to the vehicle body. Since the full opening door leaf 1 is hinged to the top cross beam of the vehicle body, when the full opening door leaf 1 is opened and turned over, the distance between the full opening door leaf 1 and the vehicle body will gradually increase, thereby gradually tightening the trigger rope 32, so that the trigger rope 32 drives the rack 33 to slide in the full opening door leaf 1, i.e. the turning over operation of the vehicle lamp 3 is realized at the same time when the full opening door leaf 1 is opened, without the need for additional operation of the vehicle lamp 3, the coordination is better, the action process is more compact, and it is particularly suitable for emergency situations.In addition, one end of the reset spring 39 is connected to the end of the rack 33 away from the trigger rope 32, and the other end of the reset spring 39 is connected to the full open door leaf 1, that is, after the rack 33 is pulled by the trigger rope 32 to realize the turnover of the vehicle lamp 3, if the full open door leaf 1 is closed downward, at this time, the reset spring 39 can reversely pull the gear to reset, so that the vehicle lamp 3 returns to the vehicle lamp mounting hole 111, and the subsequent operator can conveniently maintain and completely reset the vehicle lamp 3 by the operator.

[0030] More specifically, the full open door leaf 1 further comprises a door body 11, a hinge 12 and a first air spring 13, at this time, the hinge 12 is arranged between the top of the door body 11 and the top crossbeam of the vehicle body, that is, the hinge 12 realizes the upward and downward turnover of the door body 11 on the vehicle body, and meets the opening and closing requirements of the door body 11. At this time, the vehicle lamp 3 is mounted on the door body 11, and the door body 11 serves as the front face of the vehicle. Meanwhile, a first air spring 13 is arranged between the two sides of the door body 11 and the side walls of the vehicle frame, and the lower part of the door body 11 selectively contacts the end of the supporting rod 42 of the door leaf opening and recovery mechanism 4 away from the connecting bracket 41, that is, when opening is required, the supporting rod 42 contacts and opens the door body 11, so that the door body 11 is turned upward, and when the turnover reaches a certain angle, the critical point of the action of the first air spring 13 is reached, at this time, the door body 11 is turned upward by the first air spring 13, and the supporting rod 42 is away from the door body 11 and is reversely recovered, which meets the opening requirements of the full open door leaf 1.

[0031] More specifically, the evacuation ramp 2 mounted on the floor of the vehicle body further comprises a mounting bracket 21, a plurality of connecting rods 22, a plurality of stepping plates 23 and a second air spring 24, at this time, the mounting bracket 21 is vertically and fixedly mounted on the floor of the vehicle body, and is arranged beside the bracket 41 to prevent the door leaf opening and recovery mechanism 4 from affecting the unfolding of the evacuation ramp 2.
