Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0025] Example 1:

[0026] Please see Figure 1 - Figure 5As shown, a subway car platform clearance compensation tread includes a base 1 and a tongue plate 2. At least two T-shaped guide rails 11 are symmetrically arranged on the base 1, and at least two T-shaped grooves 21 are symmetrically formed on the tongue plate 2. The two T-shaped guide rails 11 are slidably connected in the two T-shaped grooves 21 respectively. Multiple T-shaped guide rails 11 are provided on both the base 1 and the tongue plate 2, and are evenly distributed horizontally. Multiple base plates 3 are provided on the base 1, with multiple first screw holes 31 on the sides and multiple evenly distributed horizontal insertion holes 32 on the top. Each base 1 is provided with a drive assembly 4. The base 1 is the basic support structure of the entire device, used for installing and fixing other components. The T-shaped guide rails 11 cooperate with the T-shaped grooves 21 on the tongue plate 2 to provide guidance, allowing the tongue plate 2 to slide smoothly along a predetermined trajectory and avoid uneven movement. If deviation or jamming occurs during the movement, the tongue plate 2 is the part that directly contacts the gap between the subway car door and the platform. It has at least two T-shaped grooves 21 symmetrically opened on it. These grooves cooperate with the T-shaped guide rails 11 on the base 1 to realize the sliding function of the tongue plate 2. The movement of the tongue plate 2 is controlled by the drive assembly 4 to compensate for the gap between the subway car door and the platform. The upper cover plate 3 plays the role of protecting and fixing the internal structure. It has multiple first screw holes 31 on its side for connecting and fixing with the external structure. The upper cover plate 3 is connected and fixed to the external structure by bolts 433 to ensure the stability of the entire device. Multiple insertion holes 32 are opened on the top of the upper cover plate 3 for inserting a rocker arm to drive the retraction assembly 5 to work. The drive assembly 4 is the power source for the movement of the tongue plate 2, which is used to push or pull the tongue plate 2 to realize the extension and retraction of the tongue plate 2.

[0027] The drive assembly 4 includes a slot 41 formed on the tongue plate 2, an electric push rod 42 fixedly connected to the base 1, and a connecting member 43 provided on the output end of the electric push rod 42. The slot 41 is formed on the tongue plate 2 to accommodate the electric push rod 42 and the connecting member 43 in the drive assembly 4, ensuring that the drive assembly 4 can work normally. Through the extension and retraction of the electric push rod 42, the tongue plate 2 is pushed or pulled to realize the extension and retraction of the tongue plate 2. The connecting member 43 is used to connect the output end of the electric push rod 42 to the tongue plate 2 to ensure that the electric push rod 42 can effectively drive the tongue plate 2 to move.

[0028] Specifically, the connecting component 43 includes a connecting buckle 431 fixedly connected to the output end of the electric actuator 42. The connecting buckle 431 has a second screw hole 432. The tongue plate 2 is provided with a bolt 433. The connecting buckle 431 is used to connect to the tongue plate 2 through the bolt 433, fixing the tongue plate 2 and the output end of the electric actuator 42 together. The second screw hole 432 is used to connect to the tongue plate 2 through the bolt 433. The bolt 433 is used to connect the tongue plate 2 and the connecting buckle 431 through the second screw hole 432, thereby fixing the tongue plate 2 and the output end of the electric actuator 42 together, ensuring that the electric actuator 42 can effectively drive the tongue plate 2 to move.

[0029] Furthermore, the bolt 433 is threaded into the second screw hole 432, and the drive assembly 4 is set in the slot 41 to ensure that the drive assembly 4 can work normally.

[0030] As can be seen from the above, the entire device is installed at the opening of the subway station door. The upper cover plate 3 is connected and fixed to the subway car body through the first screw hole 31. When the subway door is opened, the electric push rod 42 receives the control signal and extends and retracts. Through the connecting component 43, it pushes the tongue plate 2 to extend along the T-shaped guide rail 11 and T-shaped slide 21 to compensate for the gap between the subway door and the platform. When the subway door is closed, the electric push rod 42 extends and retracts in the opposite direction. Through the connecting component 43, it pulls the tongue plate 2 back to the initial position. Through the electric push rod 42 of the drive component 4, the tongue plate 2 is automatically extended and retracted through the connecting component 43, which effectively compensates for the gap between the subway door and the platform, making it convenient for passengers to get on and off the train. It also makes it less likely for passengers carrying luggage, pushing strollers, or with mobility difficulties to trip over the gap, preventing falls and injuries. Furthermore, it prevents passengers' feet or luggage from being caught between the door and the platform, avoiding the phenomenon of pinching or damaging luggage.

[0031] Example 2:

[0032] Please see Figure 4 - Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that each base 1 is provided with a recycling component 5. The recycling component 5 includes a rotating seat 51 rotatably connected to the bottom plate of the base 1. The top of the rotating seat 51 is provided with a hexagonal hole 52. The recycling component 5 is an emergency device for manually retracting the tongue plate 2 when the drive component 4 fails. The rotation of the rotating seat 51 pulls the tongue plate 2 back through the steel wire 53. The hexagonal hole 52 is used to insert a rocker arm to drive the rotating seat 51 to rotate.

[0033] Specifically, the recycling assembly 5 also includes a steel wire 53 mounted on a rotating seat 51. A baffle 54 is fixedly connected to the rotating seat 51. The steel wire 53 is used to pull back the tongue plate 2. The baffle 54 is used to protect the steel wire 53 and to limit the rotation angle of the rotating seat 51, ensuring that the recycling assembly 5 can work normally.

[0034] Furthermore, the hexagonal hole 52 is connected to the insertion hole 32 to ensure that the rocker arm can be smoothly inserted and drive the rotating seat 51 to rotate. The two ends of the steel wire 53 are fixedly connected to the rotating seat 51 and the tongue plate 2 respectively. When the rotating seat 51 rotates, the steel wire 53 is pulled, thereby driving the tongue plate 2 to retract. The top of the baffle 54 is set on the rotating seat 51.

[0035] As can be seen from the above, when the drive component 4 malfunctions and the electric push rod 42 cannot work properly, the tongue plate 2 needs to be manually retracted. The rocker arm is inserted into the insertion hole 32 on the top of the upper cover plate 3, and the hexagonal end of the rocker arm is inserted into the hexagonal hole 52 on the top of the rotating seat 51. By rotating the rocker arm, the rotating seat 51 is driven to rotate, and the steel wire 53 is pulled, thereby driving the tongue plate 2 to retract along the T-shaped guide rail 11 and the T-shaped slide 21 and return to the initial position, ensuring the safety and reliability of the device.
