The bottom of the outer cylinder is fixedly assembled with the top of the foot protection subplate.

[0007] As a preferred embodiment of this utility model, a magnetic ring is fixedly mounted at the bottom of the slide cylinder, a coil is fixedly sleeved on the inner wall of the outer cylinder near the bottom, and the inner wall of the coil is slidably sleeved with the outer edge of the magnetic ring. A spring is fixedly connected to the top of the outer cylinder, and the top of the spring is fixedly connected to the top of the inner wall of the foot protector main board.

[0008] As a preferred embodiment of this utility model, an auxiliary cylinder is fixedly mounted on the side of the side frame, and a rotating rod is rotatably sleeved on the inner wall of the auxiliary cylinder, with the outer edge of the rotating rod passing through the inner wall of the side frame and fixedly sleeved on the inner wall of the mounting plate.

[0010] As a preferred embodiment of this utility model, a motor is fixedly mounted on the side of the inner wall of the auxiliary frame, and a winding wheel is fixedly sleeved on the output shaft of the motor, with the outer edge of the winding wheel fixedly connected to the end of the connecting rope away from the circular plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This foldable elevator foot protection plate assembly, through the cooperation of the sliding rod and the inner cylinder, when the bottom of the foot protection plate is impacted, the side of the foot protection plate slides on the inner wall of the foot protection main plate, thereby driving the outer edge of the sliding rod to slide in the inner wall of the inner cylinder, the outer edge of the sliding cylinder to slide in the inner wall of the outer cylinder, and driving the inner wall of the sliding cylinder to slide on the outer edge of the inner cylinder. Then, the sliding cylinder drives the outer edge of the magnet ring to slide in the inner wall of the coil, thereby using the coil to generate electromagnetic damping on the magnet ring, thereby assisting the sliding cylinder to drive the foot protection plate to perform shock absorption protection. Furthermore, the spring at the top of the outer cylinder assists in pushing the outer cylinder to move away from the inner wall of the foot protection main plate, thereby assisting the foot protection plate to reset.

[0013] 2. This foldable elevator foot protection plate assembly, through the cooperation of the mounting plate and the auxiliary foot protection plate, utilizes a motor to drive a winding wheel to rotate. This winding wheel, via a connecting rope, drives a circular plate, which in turn drives the auxiliary foot protection plate to rotate. The auxiliary foot protection plate, in turn, drives the main foot protection plate to rotate. This allows for easy adjustment of the angles of the main and auxiliary foot protection plates as needed. The main and auxiliary foot protection plates push the mounting plate to rotate into the inner wall of the side frame until the sides of the main and auxiliary foot protection plates separate from the sides of the mounting plate. A torsion spring then pushes the mounting plate back to its original position. The top of the mounting plate supports the main and auxiliary foot protection plates, ensuring stable folding and storage of the auxiliary and main foot protection plates.

Through the cooperation of the foot protection main plate 3 and the foot protection sub-plate 4, the side of the foot protection sub-plate 4 slides on the inner wall of the foot protection main plate 3, thereby helping to reduce the impact on the bottom of the foot protection sub-plate 4. Through the cooperation of the circular plate 12 and the connecting rope 13, the connecting rope 13 drives the circular plate 12 to move, and the circular plate 12 drives the foot protection main plate 3 to rotate through the foot protection sub-plate 4.

[0022] In a preferred embodiment, a slide cylinder 6 is fixedly sleeved on the outer edge of the slide rod 5 near its top, and the top of the slide cylinder 6 is fixedly assembled with the top of the inner wall of the foot protection main plate 3.

The bottom of the outer cylinder 8 is fixedly assembled with the top of the foot protection sub-plate 4. Through the cooperation of the slide cylinder 6 and the inner cylinder 7, the outer edge of the slide rod 5 slides in the inner wall of the inner cylinder 7, and the inner wall of the slide cylinder 6 slides in the outer edge of the inner cylinder 7. The outer edge of the slide cylinder 6 slides in the inner wall of the outer cylinder 8, thereby providing auxiliary limiting for the movement path of the side of the foot protection sub-plate 4 on the inner wall of the foot protection main plate 3.

[0023] In a preferred embodiment, a magnet ring 10 is fixedly mounted on the bottom of the slide cylinder 6, and a coil 9 is fixedly sleeved on the inner wall of the outer cylinder 8 near the bottom.

Through the cooperation of the magnet ring 10 and the coil 9, when the slide cylinder 6 drives the magnet ring 10 to move, the outer edge of the magnet ring 10 slides in the inner wall of the coil 9, thereby generating electromagnetic damping on the magnet ring 10 by the coil 9, which in turn assists the slide cylinder 6 in shock absorption. The spring 11 is pushed down by the top of the inner wall of the foot protection main board 3, which in turn assists the outer cylinder 8 in moving down and resetting.

[0024] In a preferred embodiment, an auxiliary cylinder 19 is fixedly mounted on the side of the side frame 17. A rotating rod 20 is rotatably sleeved on the inner wall of the auxiliary cylinder 19, and the outer edge of the rotating rod 20 passes through the inner wall of the side frame 17 and is fixedly sleeved on the inner wall of the mounting plate 18. Through the cooperation of the rotating rod 20 and the auxiliary cylinder 19, the outer edge of the rotating rod 20 rotates in the inner wall of the auxiliary cylinder 19, thereby driving the side of the mounting plate 18 to rotate in the inner wall of the side frame 17. The length of the side of the mounting plate 18 is a, the height of the inner wall of the side frame 17 is b, and the length and width of the side of the main foot protector 3 are c, and c+a<b, thereby ensuring that the rotation of the main foot protector 3 pushes the mounting plate 18 to rotate and be stored in the inner wall of the side frame 17.

[0025] In a preferred embodiment, the bottom of the mounting plate 18 overlaps with the bottom of the inner wall of the side frame 17. A torsion spring 21 is provided on the inner wall of the auxiliary cylinder 19. One end of the torsion spring 21 is fixedly connected to the inner wall of the auxiliary cylinder 19, and the other end of the torsion spring 21 is fixedly connected to the outer edge of the rotating rod 20. Through the cooperation of the torsion spring 21 and the rotating rod 20, the torsion spring 21 pulls the rotating rod 20 to reset in the inner wall of the auxiliary cylinder 19, thereby using the rotating rod 20 to drive the mounting plate 18 to reset, and then the bottom of the auxiliary mounting plate 18 overlaps with the bottom of the foot protection main plate 3.

[0026] In a preferred embodiment, a motor 15 is fixedly mounted on the side of the inner wall of the auxiliary frame 14. The output shaft of the motor 15 is fixedly sleeved with a winding wheel 16, and the outer edge of the winding wheel 16 is fixedly connected to the end of the connecting rope 13 away from the circular plate 12.

[0027] Working principle: When the device is in use, when the bottom of the foot protection plate 4 is impacted, the side of the foot protection plate 4 slides on the inner wall of the foot protection plate 3, thereby causing the outer edge of the slide rod 5 to slide in the inner wall of the inner cylinder 7, and the outer edge of the slide cylinder 6 to slide in the inner wall of the outer cylinder 8, and causing the inner wall of the slide cylinder 6 to slide on the outer edge of the inner cylinder 7. This, in turn, causes the outer edge of the magnet ring 10 to slide in the inner wall of the coil 9, thereby generating electromagnetic damping on the magnet ring 10 using the coil 9. This assists the slide cylinder 6 in driving the foot protection plate 4 for shock absorption and protection. Furthermore, the spring 11 at the top of the outer cylinder 8 assists in pushing the outer cylinder 8 away from the inner wall of the foot protection plate 3, thereby assisting the foot protection plate 4 in resetting. The motor... 15 drives the winding wheel 16 to rotate, thereby using the winding wheel 16 to drive the circular plate 12 through the connecting rope 13, and using the circular plate 12 to drive the foot protection sub-plate 4 to rotate, and using the foot protection sub-plate 4 to drive the foot protection main plate 3 to rotate, so that the angle of the foot protection main plate 3 and the foot protection sub-plate 4 can be adjusted as needed. The foot protection main plate 3 and the foot protection sub-plate 4 push the mounting plate 18 to rotate into the inner wall of the side frame 17 until the sides of the foot protection main plate 3 and the foot protection sub-plate 4 separate from the sides of the mounting plate 18. Then, the torsion spring 21 pushes the mounting plate 18 to reset, and the top of the mounting plate 18 supports the foot protection main plate 3 and the foot protection sub-plate 4, thereby ensuring that the foot protection sub-plate 4 and the foot protection main plate 3 are stably folded and stored.
