[0019] like Figures 1 to 3 As shown, an automatically foldable passenger platform with guardrails includes a vertical beam support structure 1 and a folding base frame 3. The vertical beam support structure 1 is slidably connected to a fixed track via a guide device 5, and the vertical beam support structure 1 is connected to an external power unit via a traction wire rope 7. The folding base frame 3 consists of a fixed base frame 3-1 and a rotating base frame 3-2. The fixed base frame 3-1 is fixedly connected to the vertical beam support structure 1 at one end and hinged to one end of the rotating base frame 3-2 at the other end. Connecting lugs 3-3 are provided on both sides of the middle of the rotating base frame 3-2. The cylinder seat of the electric push cylinder 4 is hinged to the bottom of the vertical beam support structure 1, and the piston rod of the electric push cylinder 4 is hinged to the connecting lugs 3-3. A folding guardrail device 2 is provided on the outer periphery of the upper end of the folding base frame 3. When the electric push cylinder 4 retracts, the rotating base frame 3-2 flips upward about the hinge axis, realizing the folding function of the folding base frame 3.

The fixed guardrail 2-1 is fixedly connected to both sides of the upper surface of the fixed bottom frame 3-1; the folding guardrail 2-2 is hinged to the outer end of the rotating bottom frame 3-2 through a rotating shaft, and a plurality of swing rods 2-3 are movably hinged on the folding guardrail 2-2. The ends of the swing rods 2-3 are hinged to the ears set on the fixed guardrail 2-1; the horizontal plane and the vertical plane where the axis of each swing rod 2-3 are located are parallel and different. When the rotating bottom frame 3-2 flips upward, the folding guardrail 2-2 is pushed up, and the swing rods 2-3 rotate upward at the same time, realizing the overall folding state of the guardrail, as shown in FIG. Figure 6 shown.
