[0031] Embodiment 1: The shape of the first protective block 5 is matched with the shape of the first protective groove 6, and the shape of the second protective block 7 is matched with the shape of the second protective groove 8. The side surfaces of the first protective block 5 and the second protective block 7 are both raised arc surfaces. By respectively arranging the first protective block 5 and the second protective block 8 on the first door 3 and the second door 4, when the two doors are merged and closed, the first protective block 5 and the second protective block 8 are staggered to form an arc surface closed from bottom to top. Under the action of the arc surface, the arms and the like at the intersection of the protective blocks can be lifted upward, and the merging of the arc surfaces causes the door gap to close slowly from bottom to top, thereby reminding passengers to lift up their arms, clothes and the like and retract them, which plays a protective role in the closing of the door. When the door is closed, the lower part of the door closes earlier than the upper part, and it can also timely prevent passengers who are waiting to enter, thereby improving the safety factor when the subway door is closed and playing a protective effect.
[0032] Embodiment 2: Electric slide rails 9 are provided at the top and bottom of the subway door frame 1 and the storage groove 2. The subway door frame 1 and the storage groove 2 are slidably connected with the first door 3 and the second door 4 through the electric slide rails 9. The width of the storage groove 2 is adapted to the width of the first door 3. By arranging the storage groove 2 and the electric slide rails 9 on the subway door frame 1, the first door 3 and the second door 4 can be slid open and closed, and when the doors are opened, the two doors slide outward into the storage groove 2, so that the doors are opened to allow passengers to enter and exit.
[0033] Embodiment 3: A protection strip 10 is provided on the inner side of the first protection block 5 and the second protection block 7, and the direction of the protection strip 10 is respectively adapted to the inner direction of the first protection block 5 and the second protection block 7. An arc groove 11 is provided on the inner side of the first protection groove 6 and the second protection groove 8, and the shape of the arc groove 11 is adapted to the shape of the protection strip 10. By providing the protection strip 10 on the inner side of the first protection block 5 and the second protection block 7, the protection strip 10 can further protect the clamped arm or clothing when the two interact with each other, and can be lifted up and removed from the vehicle door in time under the action of the upward lifting force of the protection strip 10.
