Description

Technical Field

[0001] This application relates to the field of rail transit equipment technology, and in particular to a barrier-free ramp. Background Technology

[0002] Accessible ramps in subway operations are mainly used to bridge gaps and height differences between train doors and platforms, ensuring that people with mobility impairments (such as wheelchair users, the elderly, pregnant women, and passengers carrying large luggage) can safely and smoothly enter and exit the carriages. They effectively reduce the risk of tripping and falling due to height differences or gaps, thus improving the accessibility of subway services.

[0003] The application of barrier-free ramps not only reflects the humanization and inclusiveness of urban rail transit, but also meets the requirements of modern public transportation for barrier-free environment construction, and promotes the safety and fairness of subway operation.

[0004] The existing three-fold accessible ramps need to be manually unfolded by subway staff and placed at an angle on the ground. They are not secured to the platform or train, making it easy for wheelchairs to slide when crossing, affecting safety. Staff need to press them down with their hands or feet to stabilize them, which increases their workload and is detrimental to improving the convenience and stability of subway accessibility services. Summary of the Invention

[0005] This application provides an accessible ramp that overcomes at least one or more problems existing in the prior art.

[0006] A barrier-free ramp is provided, comprising three plates that are hinged in sequence. Each plate has an upper flexible plate and a lower flexible plate at its two ends. The plates on both sides can be folded toward the upper and lower surfaces of the plate in the middle. At least one plate is slidably connected to a slider on its underside.

[0007] In one possible implementation, a groove is provided on the bottom side of the plate near the upper flexible plate, and a slider is installed within the groove. Under the action of gravity, the slider can slide within the groove: when the bottom of the plate is facing down, the slider partially slides out of the groove; when the top of the plate is facing down, the slider slides completely into the groove.

[0008] In one possible implementation, the slider is T-shaped, and the groove opening is provided with a baffle to prevent the slider from completely disengaging.

[0009] In one possible implementation, the side of the plate is provided with several shafts, and the corresponding shafts of adjacent plates are connected by bushings, leaving a gap between the two connected plates.

[0010] In one possible implementation, the upper flexible plate is made of flexible material at least at the connection point with the plate body. When the plate body is placed at an angle, the upper flexible plate droops under the influence of gravity, with its bottom surface touching the ground.

[0011] In one possible implementation, the lower flexible plate is made of flexible material at least at the connection point with the plate body. When the plate body is placed at an angle, the lower flexible plate folds to one side of the plate body, with its underside touching the ground.

[0012] In one possible implementation, both the upper and lower flexible plates are wedge-shaped with their inclined surfaces facing outwards.

[0013] In one possible implementation, the surface of the upper flexible plate is provided with several transversely arranged grooves; the underside of the lower flexible plate is provided with anti-slip texture.

[0014] In one possible implementation, a horizontally positioned clearance groove is provided at the top of the connection between the lower flexible plate and the plate body.

[0015] Compared with the prior art, this utility model has the following advantages: The slider and the groove in the barrier-free ramp provided in this application cooperate to limit the ramp after it is placed, preventing displacement when the wheelchair is squeezed, eliminating the need for subway staff to step on and fix it throughout the process, thus reducing the operational burden; the upper and lower flexible plates can be folded relative to the plate body, increasing the adhesion to the ground and the anti-slip performance, and also avoiding interference when folding; the overall structure is simple, the production cost is low, and it is easy to promote and apply, which can effectively improve the user experience and operational efficiency of the barrier-free facilities in the subway.

[0016] It should be noted that all the above possible implementation methods can be combined, provided that the solutions do not contradict each other. Attached Figure Description

[0025] The present application will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present application. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and to fully illustrate the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0026] An embodiment of this application provides a barrier-free ramp, please refer to it as well. Figure 1 and Figure 2 The transition plate is composed of three plates 10 connected sequentially by a pivot. Each plate 10 has an upper flexible plate 20 and a lower flexible plate 30 at both ends. The plates 10 on both sides can be folded towards the upper and lower surfaces of the middle plate 10, resulting in a three-layer stacked structure after folding. The bottom of the middle plate 10 is slidably connected to a slider 13.

[0027] For details, please refer to Figure 3 , Figure 3 The interaction between slider 13 and groove 12 is shown. A groove 12 is located on the bottom of plate 10 near the upper flexible plate 20, and slider 13 is positioned within the groove 12. Under gravity, slider 13 can slide within the groove 12. When plate 10 is facing down, slider 13 partially slides out of groove 12. Because slider 13 is T-shaped, its end is limited by a baffle at the opening of groove 12, preventing it from completely exiting groove 12. When plate 10 is facing up, slider 13 slides completely into groove 12, without affecting the folding of the plate.

[0028] In one possible implementation, the side of the plate 10 is provided with several shafts 11, and the corresponding shafts 11 of adjacent plates 10 are connected by bushings 40. After the bushings 40 are connected, a gap is left between the two plates 10 to avoid interference when folding.

[0029] Please see Figure 6 , Figure 6 The diagram illustrates the use of the flexible platform. The upper flexible platform 20, placed facing the train door, is made of flexible material and hangs naturally under gravity, conforming to the ground. Flexible materials are typically made of polyurethane, rubber, etc., possessing good flexibility and wear resistance.

[0030] Furthermore, the main body of the upper flexible plate 20 is made of rigid material. Common rigid materials include polyetheretherketone, polyamide, and polycarbonate, which have good corrosion resistance and mechanical strength. To ensure that the upper flexible plate 20 can still bend at a certain angle while connected to the plate body 10, a flexible material is used at the connection point, so that the outer end of the upper flexible plate 20 can better fit the ground.

[0031] The lower flexible plate 30 is also made of flexible material and can be folded upwards under external force, with its bottom surface in contact with the ground. When the main body of the lower flexible plate 30 is made of rigid material, the connection between it and the plate 10 must be made of at least flexible material to ensure a certain degree of flexibility.

[0032] In one possible implementation, both the upper flexible plate 20 and the lower flexible plate 30 are wedge-shaped with their inclined surfaces facing outwards.

[0033] In some cases, the surface of the upper flexible plate 20 is provided with a number of transversely arranged grooves 21. When the upper flexible plate 20 is made of a flexible material, these grooves 21 help it bend downwards and also serve as an anti-slip function.

[0034] The lower flexible plate 30 has anti-slip texture 31 on its underside to enhance friction with the ground and prevent the tread from shifting towards the platform when a wheelchair gets off.

[0035] When the flexible plate 30 is made of rigid material, in order to avoid interference after it rotates relative to the plate body 10, a transverse clearance groove 32 is provided at the top of the connection between the lower flexible plate 30 and the plate body 10.

[0036] Please refer to the following: Figure 4 and Figure 5 The two side plates 10 can be folded towards the top and bottom of the middle plate 10, forming a "Z" shape. During this process, the slider 13 gradually slides into the groove 12, and finally the three plates 10 are stacked from top to bottom to form a shape like... Figure 4 The storage configuration shown makes it easy to store.

[0037] In use, lift the top plate 10 by hand, while the other two plates 10 hang down naturally. Place the transition plate between the train door and the platform, with one side of the upper flexible plate 20 facing the train door and the other side of the slider 13 facing downwards. The slider 13 slides out of the groove 12 under gravity. Gently push the transition plate so that the slider 13 rests against the bottom of the train door. Figure 6 As shown. At this time, when the wheelchair passes by and applies a pushing force to move the ramp towards the train door, the slider 13 acts as a limit to prevent the ramp from shifting.

[0038] When a wheelchair disembarks, the lower flexible plate 30 provides friction, restricting the movement of the ramp. This design effectively reduces the pushing and displacement of the ramp when a wheelchair gets on or off, and reduces the operational burden on subway staff who need to constantly step on and stabilize the ramp. The overall structure is simple, the production cost is low, and it is easy to promote and apply.

[0039] While exemplary embodiments of this application have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this application without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this application as defined by the claims.
