[0020] In order 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 introduced in detail below in conjunction with the accompanying drawings.

[0021] As shown in Figures 1-3 A door leaf applied to a rail vehicle door includes a bottom plate 1. A sliding groove 11 is opened on the bottom plate 1. A door body 2 is slidably arranged in the sliding groove 11 respectively. A buffer layer 34 is arranged on the door body 2. A plurality of fixing blocks 35 arranged in a linear array are arranged in the buffer layer 34. A sliding groove 36 is opened in the fixing block 35. An elastic member 37 is arranged in the sliding groove 36. A sliding rod 38 is slidably arranged in the sliding groove 36. The elastic member 37 is fixedly arranged on the elastic member 37.

[0022] Specifically, if the door body 2 is impacted, it will contact the buffer layer 34. At the same time, the sliding rod 38 on the fixing block 35 in the buffer layer 34 slides. The sliding rod 38 slides in the sliding groove 36 opened on the fixing block 35. Then when the sliding rod 38 moves in the sliding groove 36, the elastic member 37 is stressed to relieve the impact force. After the impact ends, the elastic member 37 releases the force, pushes the sliding rod 38 to slide outward in the sliding groove 36, and pushes the buffer layer 34 to reset the buffer layer 34.

[0023] In the above solution, the door body 2 slides on the sliding groove 11 of the bottom plate 1 through the sliding groove 11 on the bottom plate 1. Through the buffer layer 34 on the door body 2, when the door body 2 is impacted, it can be buffered, realizing the protection of the door body 2 and the passengers. Through the fixing block 35 in the buffer layer 34 and the sliding groove 36 in the fixing block 35, the sliding rod 38 slides in the buffer layer 34 to realize the buffering of the impact on the door body 2. Through the elastic member 37, after the buffer layer 34 of the door body 2 is impacted, it is reset.

[0024] As a further embodiment provided by the present utility model, according to Figure 2 and Figure 3 As shown, a first placement groove 23 is opened on the door body 2, and a heat preservation board 24 is arranged in the first placement groove 23.

[0025] Specifically, the door body 2 is heat-preserved through the heat preservation board 24 in the first placement groove 23.

[0026] As a further embodiment provided by the present utility model, according to Figure 2 and Figure 3 As shown, a second placement groove 25 is opened on the door body 2, a sound insulation board 26 is arranged in the second placement groove 25, and a plurality of sound insulation holes 27 arranged in a linear array are opened on the sound insulation board 26.

[0027] Specifically, the sound insulation board 26 in the second placement groove 25 is used to insulate the interior of the carriage. When sound enters the sound insulation board 26, it will enter the sound insulation holes 27 for absorption.

[0028] As a further embodiment provided by the present utility model, according to Figure 2 and Figure 3 As shown, a third placement groove 28 is formed in the door body 2, and a plurality of pressure-resistant plates 29 arranged in a linear array are staggered in the third placement groove 28.

[0029] Specifically, when being subjected to a relatively strong impact, the pressure-resistant plates 29 in the third placement groove 28 strengthen the strength of the door body 2.

[0030] As a further embodiment provided by the present utility model, according to Figure 2 and Figure 3 As shown, a fourth placement groove 30 is formed in the door body 2, and a plurality of vertical rods 31 and horizontal rods 32 arranged in a linear array are respectively arranged in the fourth placement groove 30. The plurality of vertical rods 31 and the plurality of horizontal rods 32 are cross-arranged to form a reinforcement plate 33.

[0031] Specifically, by the staggered arrangement of the vertical rods 31 and the horizontal rods 32 in the fourth placement groove 30, the strength of the door body 2 is further enhanced.

[0032] As a further embodiment provided by the present utility model, according to Figure 2 and Figure 3 As shown, a slider 21 is provided at the bottom of the door body 2, and the slider 21 is slidably arranged in the chute 11.

[0033] Specifically, the door body 2 slides in the chute 11 on the bottom plate 1 through the slider 21.

[0034] Working principle: If the door body 2 is impacted, it will contact the buffer layer 34. At the same time, the sliding rod 38 on the fixed block 35 in the buffer layer 34 slides, and the sliding rod 38 slides in the sliding groove 36 opened on the fixed block 35. Then when the sliding rod 38 moves in the sliding groove 36, the elastic member 37 is stressed to relieve the impact force. After the impact ends, the elastic member 37 releases the force, pushes the sliding rod 38 to slide outward in the sliding groove 36, and pushes the buffer layer 34 to reset the buffer layer 34. At the same time, when being subjected to a relatively strong impact, the pressure-resistant plates 29 in the third placement groove 28 strengthen the strength of the door body 2. By the staggered arrangement of the vertical rods 31 and the horizontal rods 32 in the fourth placement groove 30, the strength of the door body 2 is further enhanced, and the strength of the door body 2 is further improved. Rain is prevented from entering the carriage by the rain shield 22 provided on the door body 2.

[0035] Only some exemplary embodiments of the present utility model have been described by way of illustration. 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 description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
