Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit technology, specifically an anti-collision structure for a platform safety step. Background Technology
[0002] During the construction of rail transit, in order to ensure the safe operation of trains, a certain gap is often left between the platform and the train body, which brings certain safety hazards and inconvenience to passengers. To facilitate the passage of wheelchairs, step stools are usually needed for assistance. In order to avoid train collisions and scrapes against the step stools, the step stools are usually made portable and laid out by station staff.
[0003] Currently, when installing the step stools, station staff need to actively notice wheelchair users and manually retrieve and place them between the platform and the train doors. If staff fail to notice wheelchair users in time, or if it is during train arrival or when passenger boarding and alighting time is tight, it is often difficult to complete the process of retrieving and installing the step stools in a timely manner, resulting in inconvenience. It is not convenient to directly install the step stools on the platform to prevent train collisions and scrapes. When needed, wheelchair users should install them themselves. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-collision structure for a platform safety step to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A collision-resistant structure for a platform safety step includes:
[0007] A crash barrier is hinged to one end of the pedal, and a storage compartment is fixedly installed on the lower surface of the pedal;
[0008] A sensing component is disposed on one side of the pedal. The sensing component includes two storage slots opened on the surface of one side of the pedal. A sliding groove is opened at one end of the storage slot. A pressure block is slidably connected inside the sliding groove. A second pressure sensor is fixedly installed at one end inside the sliding groove.
[0009] The lifting assembly is installed inside the placement compartment;
[0010] The reset component is located inside the placement chamber.
[0011] Furthermore, the upper surface of the pedal is provided with an inspection port, a cover plate is movably embedded inside the inspection port, a control module is fixedly installed inside the placement compartment, and a pressure sensor is fixedly embedded on one side of the anti-collision plate.
[0012] Furthermore, the lifting assembly includes:
[0013] An electric push rod is fixedly installed on the inner surface of the placement chamber;
[0014] The push block is fixedly installed at the output end of the electric push rod and slides through the pedal.
[0015] Furthermore, the storage groove is hinged with a flap, and a sliding rod is symmetrically fixed at one end of the sliding groove. A through hole is symmetrically opened on one side surface of the pressure block, and the sliding rod is slidably connected to the through hole at the corresponding position.
[0016] Preferably, the other end of the pressure block is inclined at the point where it fits against the flip plate, and a spring is fixedly connected to the outside of the slide rod between the pressure block and the slide groove.
[0017] Furthermore, the reset component includes:
[0018] The winding drum is rotatably connected to the inner surface of the placement chamber via a bracket;
[0019] The pull rope is wound around the outer surface of the take-up drum.
[0020] Preferably, one end of the pull rope passes through the pedal and is fixedly connected to the anti-collision plate, and a motor capable of driving the winding drum to rotate is fixedly installed on the inner surface of the placement chamber.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. By aligning the wheelchair wheels with the storage slot, when the wheels press against the flip plate, the flip plate moves down, and the wheels continue to move, pushing the pressure block to slide and press the second pressure sensor. Then, the electric push rod extends, pushing the push block upward and flipping the anti-collision plate. The wheelchair user's feet push the anti-collision plate to flip and lay it at the train door. Then the push block returns to its original position. Thus, when a wheelchair user needs to board the train, the wheelchair user can push the anti-collision plate to lay it between the platform and the train door, while avoiding the train colliding with the pedals. This makes the anti-collision plate easy to lay and store quickly, making it convenient to use.
[0023] 2. After the wheelchair user enters the train, the No. 1 pressure sensor detects that the gravity above the anti-collision plate has decreased. The motor then starts, rewinds the pull rope, and pulls the anti-collision plate to reset, allowing the anti-collision plate to automatically reset and reducing manual operation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-5 In this embodiment of the utility model, a collision-proof structure for a platform safety step includes a collision-proof plate 101 hinged to one end of a step 1. A storage compartment 102 is fixedly installed on the lower surface of the step 1. A sensing component 2 is disposed on one side of the step 1. The sensing component 2 includes two storage slots 201 opened on one side surface of the step 1. A sliding groove 202 is opened at one end of the storage slot 201. A pressure block 205 is slidably connected inside the sliding groove 202. A second pressure sensor 204 is fixedly installed at one end inside the sliding groove 202. A lifting component 3 is disposed inside the storage compartment 102. A reset component 4 is disposed inside the storage compartment 102.
[0032] Specifically, the pedal 1 and the storage compartment 102 are buried in the platform ground, so that the pedal 1 is higher than the platform ground. When the wheelchair user needs to board the vehicle, the wheelchair wheels are aligned with the storage slot 201. The second pressure sensor 204 senses the force of the wheelchair wheels moving and controls the lifting component 3 to operate, flipping the anti-collision plate 101 upward. As the wheelchair user continues to move, the user's footsteps push the anti-collision plate 101 to be laid at the door. Then, the reset component 4 resets the anti-collision plate 101. Example 1
[0033] like Figure 4As shown, in this embodiment, an inspection port 104 is provided on the upper surface of the pedal 1, a cover plate 105 is movably embedded inside the inspection port 104, a control module 103 is fixedly installed inside the placement compartment 102, and a pressure sensor 106 is fixedly embedded on one side surface of the anti-collision plate 101.
[0034] In this embodiment, by removing the cover plate 105, the internal parts can be easily inspected through the inspection port 104. The control module 103 is electrically connected to the first pressure sensor 106, the motor 403, the electric push rod 301, and the second pressure sensor 204. It receives and processes the signals emitted by the first pressure sensor 106 and the second pressure sensor 204, and then controls the operation of the motor 403 and the electric push rod 301.
[0035] like Figure 5 As shown, in this embodiment, a flap 203 is hinged inside the storage slot 201, and a slide rod 207 is symmetrically fixedly installed at one end of the slide groove 202. A through hole 206 is symmetrically opened on one side surface of the pressure block 205, and the slide rod 207 is slidably connected to the through hole 206 at the corresponding position. The other end of the pressure block 205 is in contact with the flap 203, which is a sloped structure. The sloped structure facilitates the flap 203 to be flipped upward and reset. A spring 208 is fixedly connected to the outside of the slide rod 207 between the pressure block 205 and the slide groove 202. The lifting assembly 3 includes: an electric push rod 301 fixedly installed on the inner surface of the placement chamber 102, and a push block 302 fixedly installed on the output end of the electric push rod 301 and slidingly passing through the pedal 1.
[0036] In practice, the wheelchair wheels are aligned with the storage slot 201. When the wheels press against the flip plate 203, the flip plate 203 moves down, and the wheels continue to move, pushing the pressure block 205 to slide and press the second pressure sensor 204. Then, the electric push rod 301 extends, pushing the push block 302 upward and flipping the anti-collision plate 101. At the same time, the motor 403 runs, releasing the pull rope 402. After the train arrives at the station, the wheelchair moves, and the wheelchair user's feet push the anti-collision plate 101 to flip and lay it at the train door. Then, the push block 302 returns to its original position. Thus, when a wheelchair user needs to board the train, the wheelchair user can push the anti-collision plate 101 to lay it between the platform and the train door, while preventing the train from colliding with the pedal 1. This makes the anti-collision plate 101 easy to lay and store quickly, making it convenient to use. At the same time, the sound of the anti-collision plate 101 colliding with the train alerts passengers inside the train, leaving some space for wheelchair users. Example 2
[0037] Based on Embodiment 1, in order to solve the problem that the anti-collision plate 101 is not easy to automatically reset.
[0038] like Figure 4As shown, in this embodiment, the reset component 4 includes: a take-up drum 401 rotatably connected to the inner surface of the placement chamber 102 via a bracket, and a pull rope 402 wound around the outer surface of the take-up drum 401; one end of the pull rope 402 passes through the pedal 1 and is fixedly connected to the anti-collision plate 101, and a motor 403 capable of driving the take-up drum 401 to rotate is fixedly installed on the inner surface of the placement chamber 102.
[0039] In practice, after a wheelchair user enters the train, the No. 1 pressure sensor 106 detects a decrease in gravity above the anti-collision plate 101, the motor 403 starts, the pull rope 402 is wound up, and the anti-collision plate 101 is pulled back to reset, so that the anti-collision plate 101 can be automatically reset, reducing manual operation.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
