[0020] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] As shown in Figures 1-5 , a high - security rail vehicle safety door includes a frame 1 provided on the platform. The frame 1 is provided with a notch 11. A first door body 2 and a second door body 3 are respectively arranged in the notch 11. The first door body 2 is provided with an insertion plate 21. A slot 31 matching with the insertion plate 21 is provided on the second door body 3. A placement groove 22 is provided on the insertion plate 21. A plurality of elastic members 24 arranged in a linear array are provided in the placement groove 22. A sliding plate 26 is provided in the placement groove 22. A sensor 25 is provided between every two elastic members 24.

[0022] Specifically, when in use, the first door body 2 and the second door body 3 are controlled to open by the control center. Then, after passengers get on the vehicle, the first door body 2 and the second door body 3 are closed. When closing, the insertion plate 21 on the first door body 2 slides inward into the slot 31 on the second door body 3. When an object contacts the insertion plate 21, the insertion plate 21 moves inward. At the same time, a plurality of elastic members 24 are stressed. At this time, the sensor 25 detects and feeds back a signal to the control center.

[0023] In the above - mentioned solution, the installation of the safety door is realized through the frame 1 provided on the platform. The first door body 2 and the second door body 3 are installed through the notch 11 on the frame 1. The sealing of the first door body 2 and the second door body 3 is realized through the insertion plate 21 and the slot 31 on the first door body 2 and the second door body 3. The reset of the sliding plate 26 provided in the placement groove 22 is realized through the elastic members 24 in the placement groove 22. After the sliding plate 26 is pressed and moves inward, the sensor 25 is activated and gives a warning.

[0024] As a further embodiment provided by the present utility model, as shown in Figure 1 , Figure 2 and Figure 3 , the frame 1 is provided with a sliding groove 12, and the first door body 2 and the second door body 3 slide in the sliding groove 12.

[0025] Specifically, the first door body 2 and the second door body 3 move in the sliding groove 12 on the frame 1 under the control of the control center.

[0026] As a further embodiment provided by the present utility model, as shown in Figure 4 and Figure 5 , arc - shaped scraping plates 14 are provided on both the first door body 2 and the second door body 3.

[0027] Specifically, when the first door body 2 and the second door body 3 move, they drive the scraper 14 to move at the same time. When the scraper 14 moves, it will push away the sundries on the frame 1 to prevent ground foreign objects from affecting the fastening of the first door body 2 and the second door body 3.

[0028] As a further embodiment provided by the present utility model, according to Figure 4 As shown in the figure, a bottom frame 10 is provided at the bottom of the frame 1, and a circulation groove 13 is opened on the bottom frame 10.

[0029] Specifically, the pushed sundries are discharged through the circulation groove 13.

[0030] Working principle: When in use, the first door body 2 and the second door body 3 are controlled to open through the control center. Then, after the passengers get on the vehicle, the first door body 2 and the second door body 3 are closed. When closing, the plug plate 21 on the first door body 2 will slide inward into the slot 31 on the second door body 3. When an object contacts the plug plate 21, the plug plate 21 will move inward, and at the same time, multiple elastic members 24 are stressed. At this time, the sensor 25 detects and feeds back a signal to the control center. At the same time, when the first door body 2 and the second door body 3 move, they drive the scraper 14 to move at the same time. When the scraper 14 moves, it will push away the sundries on the frame 1 to prevent ground foreign objects from affecting the fastening of the first door body 2 and the second door body 3. Then, the pushed sundries are discharged through the circulation groove 13.

[0031] Only some exemplary embodiments of the present utility model are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
