[0001] The utility model relates to the technical field of rail transportation equipment, in particular to a platform anti-falling device using a subway door as power. Background Art
[0002] In cities, people often choose to travel by subway. There is often a safety gap of a certain width between the door of the subway car and the safety door of the platform. When the subway running on the track arrives at the destination platform, people always need to carefully cross this gap when getting on and off the train. It is especially inconvenient for disabled people with limited mobility, and they often need the assistance of platform staff to board the train. It is also common for passengers' feet to get stuck in the gap, or for people's belongings to accidentally fall into the gap. There are safety hazards in the operation of the subway, and incidents of passengers being affected by falling objects and the subway being unable to operate on time also occur from time to time.

[0023] Example 1
[0024] like Figures 1-2 A common subway car door has two leaves. When opening, the two doors move to the left and right opposite directions to open at the same time. When closing, the two doors close to the middle at the same time. This embodiment provides a platform anti-fall device powered by a subway door, which is arranged on the ground below the entrance of the subway car door 7. It includes a first rod 1 vertically arranged in the middle of the car door 7. Limiting members 4 are provided at both ends of the first rod 1. A driven hinge 2 is fixed on the first rod 1. The first rod 1 can slide relative to the inside and outside of the car under the limiting action of the limiting member, thereby driving the driven hinge 2 to move inside and outside. Two second rods 3 are hinged on the left and right sides of the driven hinge 2. The other end of the second rod 3 is hinged to the bottom of the car door 7 on both sides through an active hinge 5.
[0025] The outer end of the first rod 1 is fixedly connected with a shielding plate 10, and a third rod 11 is provided on both sides of the first rod 1. The inner end of the third rod 11 is limited by a limit member 4, and the outer end is fixedly connected to the shielding plate 10 and can slide freely in the inside and outside directions of the car. The purpose of its setting is to keep the shielding plate 10 balanced in and out and prevent it from tilting.
[0026] When the compartment door 7 is in a closed state, the driven hinge 2 is located at the innermost side of the compartment;
[0027] When the compartment door 7 is opened, the two second rods 3 drive the driven hinge 2 to move outward from the compartment, driving the first rod 1 to slide outward relative to the compartment between the two limit members 4, and sending the shielding plate 10 from the inside of the compartment door to the outside of the compartment, covering the gap between the safety door 8 and the compartment door 7 when the door is opened; when the compartment door 7 is fully opened, the shielding plate 10 has completely covered one side of the safety door 8;
[0028] When the compartment door 7 is closed, the two second rods 3 drive the driven hinge 2 to move into the compartment, driving the first rod 1 to slide inwardly relative to the compartment between the two limit members 4, and completely retracting the shielding plate 10 from outside the compartment door into the compartment.
[0029] The shielding plate 10 is trapezoidal, with its short side facing outside the car and its long side facing inside the car, and is located at the center of the car door 7. The long side width is the car door width, and the short side length is preferably 75% to 85% of the long side width.
[0030] In order to prevent the components of the device from affecting people's free activities, the device is arranged under the floor of the carriage, and the shielding plate 10 moves inside and outside between the floor of the carriage as the carriage door 7 is opened and closed.
[0031] Example 2
[0032] like Figure 1 , the driven hinge 2 pushes the first rod 1 to slide between the first limiter 41 in the direction of the inside of the carriage and the second limiter 42 near the carriage door. When the carriage door 7 is closed, the driven hinge 2 is located at the innermost side of the carriage, and the two second rods 3 are perpendicular to the carriage door 7 at the same time. At this time, the distance between the driven hinge 2 and the carriage door 7 is equal to the length L of the second rod 3, and the shielding plate 10 is pulled back into the carriage; when the carriage door 7 is opened to the maximum, the driven hinge 2 moves outside the carriage, and the two second rods 3 push the shielding plate 10 to move outside the carriage, connecting the gap between the safety door 8 and the carriage door 7. The distance moved by the driven hinge 2 and the shielding plate 10 is the same as L1, and the distance from the carriage door 7 is L-L1. The shielding width of the shielding plate 10 should be at least greater than the safety gap width E between the carriage door 7 and the safety door 8, and L is greater than or equal to half of the width D of the carriage door.
[0033] All rods are hollow circular tube structures to reduce the overall mass of the structure.
[0034] The above embodiments are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
