[0031] A power housing 21 is fixedly installed on the back of the fixed door panel 1. The first gear 22 and the second gear 24 are both located inside the power housing 21. The first gear 22 is rotatably connected inside the power housing 21. A power mechanism 25 is arranged inside the power housing 21. The power mechanism 25 is composed of a motor and a reducer. The second gear 24 is fixedly installed on the output end of the reducer. The output end of the motor is fixedly connected to the input end of the reducer. A limit rod 26 is fixedly installed inside the power housing 21. The sliding block 27 is slidably connected to the outside of the limit rod 26. A guide wheel 6 is rotatably connected to the inside of the bottom of the movable door panel 5. The bottom of the guide wheel 6 is flush with the bottom of the fixed door panel 1.

[0032] In this embodiment, when the movable door is opened and closed, the second gear 24 is driven to rotate by the rotation of the motor in cooperation with the reducer, and the second gear 24 rotates in cooperation with the first gear 22 to drive the toothed belt 23 to rotate. The rotation of the toothed belt 23 can drive the mounting block 32 thereon to move, and the movement of the mounting block 32 drives the connecting block 31 and the sliding block 27 to move, thereby driving the lower movable door panel 5 to move, thereby realizing the opening and closing of the movable door panel 5. The lower guide wheel 6 is used to ensure that the movable door panel 5 can move along the ground, and the sliding block 27 slides along the limit rod 26 when sliding, thereby ensuring the stability of the movable door panel 5 when moving.

[0033] Reference Figures 1 to 4 In one aspect of the present embodiment, an insert block 33 is fixedly mounted at the bottom of the mounting block 32, and the insert block 33 is inserted into the connection block 31.

When the movable door panel 5 touches a pedestrian, the movable door panel 5 is squeezed, and the squeezing force will act on the inside of the card block 36. The force acting on the card block 36 increases, the spring 37 contracts, and the card block 36 moves to the inside of the internal groove 35. The plug block 33 is no longer restricted by the card block 36, and the plug block 33 will move out of the connecting block 31. The movement of the toothed belt 23 can no longer drive the movable door panel 5 to move, thereby achieving the effect of the movable door panel 5 automatically stopping after touching a person. This method can ensure that when the infrared anti-pinch method fails, the material anti-pinch method can be used to continue to prevent pinching. The overall mechanical structure control is adopted, the stability is better, and it is not easy to fail.

[0035] Working principle: When the movable door is opened or closed, the motor rotates in coordination with the reducer to drive the second gear 24 to rotate, and the second gear 24 rotates in coordination with the first gear 22 to drive the toothed belt 23 to rotate. The rotation of the toothed belt 23 can drive the mounting block 32 thereon to move, and the movement of the mounting block 32 drives the connecting block 31 and the sliding block 27 to move, thereby driving the lower movable door panel 5 to move, and realizing the opening and closing of the movable door panel 5. The lower guide wheel 6 is used to ensure that the movable door panel 5 can move along the ground, and the sliding block 27 slides along the limit rod 26 when sliding, thereby ensuring the stability of the movable door panel 5 when moving. When the movable door panel 5 moves normally, the card block 36 is connected to the inside of the card slot 34, and the card block is inserted into the card slot 34. 33 drives the connecting block 31 to move, ensuring the normal movement of the movable door panel 5. When the movable door panel 5 touches a pedestrian, the movable door panel 5 is squeezed, and the squeezing force will act on the inside of the card block 36. The force on the card block 36 increases, the spring 37 contracts, and the card block 36 moves to the inside of the internal groove 35. The plug block 33 is no longer restricted by the card block 36, and the plug block 33 will move out of the connecting block 31. The movement of the toothed belt 23 can no longer drive the movable door panel 5 to move, thereby achieving the effect of the movable door panel 5 automatically stopping after touching a person. This method can ensure that when the infrared anti-pinch method fails, the material anti-pinch method can be used to continue to prevent pinching. The overall mechanical structure control is adopted, the stability is better, and it is not easy to fail.
