[0023] like Figures 1-2 As shown, according to an embodiment of the present invention, a tactile paving path is provided, which is located on a sidewalk and includes:

[0024] The support unit is inserted into the ground at its lower end. The height difference between the upper surface of the support unit and the ground is no greater than the first height difference. The support unit is made of steel. The steel support unit has a stable structure and will not deform during long-term use. At the same time, the steel support unit is easy to recycle and will not cause pollution during the recycling process.

[0025] The support unit is made of steel, with its lower end inserted below the ground to ensure a secure connection with the foundation. The height difference between the upper surface of the support unit and the surrounding ground is strictly controlled to avoid tripping risks. To adapt to different terrain requirements, the size of the support unit can be customized according to the width and direction of the sidewalk, such as using an arc structure or a segmented splicing scheme at corners. In addition, the anchoring design between the support unit and the ground can be further strengthened by side plates 2 or additional fasteners (such as screws) to ensure that the tactile paving does not shift or loosen during long-term use.

[0026] The upper surface of the support unit is provided with a first guide area and a second guide area along its length, and the guide protrusion is located in the first guide area and the second guide area. The guide protrusion includes a strip-shaped guide protrusion 3 and a circular guide protrusion 4. The strip-shaped guide protrusion is located in the first guide area, and the guide protrusion or the circular guide protrusion is located in the second guide area.

[0027] The guiding protrusions are divided into strip-shaped guiding protrusions 3 and circular guiding protrusions 4. Their functional zoning is achieved through their different shapes. Strip-shaped guiding protrusions 3 serve as standard road surface guidance, while circular guiding protrusions 4 indicate the presence of an intersection or mountain pass ahead, alerting the blind to traffic conditions. In the first guiding area, the strip-shaped guiding protrusions are arranged parallel to the length of the tactile paving. Their height and spacing conform to the foot sensory habits of visually impaired individuals, forming a continuous tactile guide line. The cross-section of the strip-shaped guiding protrusions is designed to be trapezoidal or arc-shaped to reduce shoe sole wear and enhance drainage performance. The second guiding area features circular guiding protrusions with a higher distribution density than the strip-shaped protrusions. These densely packed dots provide tactile feedback, indicating the presence of dangerous areas (such as intersections or obstacles) ahead. The tops of the circular guiding protrusions are slightly flattened to prevent sharp edges from damaging the cane or shoe sole. Both types of protrusions are fixed to the top plate 1 using stamping, casting, or welding processes, and their surfaces are treated with an anti-slip finish (such as knurling or a rubber coating).

[0028] The support unit includes a top plate 1 and side plates 2. Each side of the top plate 1 is connected to a side plate 2. Adjacent side plates 2 are connected to each other and are inserted into the ground.

[0029] The support unit consists of a top plate 1 and side plates 2. The top plate 1 serves as the load-bearing surface for the tactile paving, while the side plates 2 extend vertically and insert into the ground to provide support. Each side of the top plate 1 is connected to the side plate 2 via welding or integral molding, forming a stable box-like or "U"-shaped frame structure. Adjacent side plates 2 are tightly connected via welding, bolts, or snap-fit ​​structures to ensure the continuity and overall strength of the tactile paving base. In hard foundations, the side plates 2 can be designed with segmented insertion to avoid excessive construction difficulty. The width of the top plate 1 and the height of the side plates 2 are adapted to different pedestrian walkway scenarios; for example, a compact design can be used in narrow areas, while the area of ​​the top plate 1 can be increased in wide areas to expand the guidance range. Reinforcing ribs or folded edge structures can be added at the connection between the top plate 1 and the side plates 2 to disperse local stress and prevent deformation.

[0030] Specifically, the support unit contains concrete blocks located between the top slab 1 and the ground. These concrete blocks, situated between the top slab 1 and the ground, form the load-bearing core layer. The concrete is poured into the cavity enclosed by the top slab 1 and side slabs 2, with a mix design generally meeting high compressive strength and frost resistance requirements. After curing, the concrete forms a composite structure with the steel support unit, combining the toughness of metal with the compressive strength of concrete. Drainage channels or cable routing space can be reserved within the concrete blocks to accommodate compatibility requirements with municipal facilities. Another advantage of using concrete is lowering the center of gravity of the support unit, preventing overturning due to external impacts.

[0031] The top plate 1 has light holes 5, and each light hole 5 houses a motion sensor light. The light is connected to a solar power system, which consists of a vertical pole and solar panels mounted on the pole. This solar power system is typically used for municipal solar streetlights; the vertical pole is the streetlight pole, and the solar panels are mounted on the pole. The motion sensor light is usually connected to the streetlight's solar panels via pre-embedded wiring, which then powers the light. The top plate 1 has light holes 5 on its surface, housing the motion sensor lights. These lights typically use low-power LED light sources and can be combined with or integrated with light and motion sensors to automatically illuminate when ambient light is insufficient or when a pedestrian is detected approaching. The position of the light holes 5 avoids guiding protrusions to maintain the integrity of the tactile function. A lampshade can be installed on the light holes 5, with a frosted surface to prevent glare.

[0032] Specifically, the top plate 1 is provided with a speaker hole 6, and a speaker is installed inside the speaker hole 6. The speaker is connected to the solar power supply system. The speaker is usually a waterproof speaker, and it is typically powered by the solar panels of the street light. The speaker can be connected to a motion-sensor light or a separate sensor to play directional voice prompts (such as "Intersection ahead" or "Caution: Steps") when a pedestrian is detected passing by. The speaker's power supply system can be shared with the motion-sensor light to ensure energy efficiency.

[0033] Specifically, the surfaces of the top plate 1 and side plate 2 are coated with a galvanized layer. This galvanized layer effectively isolates the steel from external moisture and salt, slowing down the corrosion process. The galvanizing process also reduces the surface friction coefficient, preventing pedestrians from slipping. Furthermore, the gloss level of the galvanized layer can be adjusted to suit the aesthetic requirements of different scenarios.

[0034] Specifically, the thickness of the top plate 1 and the side plate 2 is 3mm-5mm. The thickness of the top plate 1 and the side plate 2 can be 3mm, 3.5mm, 4mm, 4.5mm, or 5mm, preferably 4mm. The thickness of the top plate 1 and the side plate 2 reduces the overall weight while ensuring structural strength.

[0035] Preferably, the length of the roof slab 1 is 0.5m-4m. The length of the roof slab 1 is usually modularly designed according to construction conditions. A single roof slab 1 can be installed independently or spliced ​​to form a continuous path. Typically, the length of the roof slab 1 can be 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, or 4.0mm. Shorter roof slabs 1 are suitable for narrow or winding road sections, while longer roof slabs 1 can reduce the number of joints and reduce maintenance frequency.

[0036] Specifically, the top plate 1 has a fixing hole 7 located in the middle of the top plate 1. A fixing screw 8 is installed in the fixing hole 7, and the lower end of the fixing screw 8 extends into the ground. The fixing hole 7 is located in the middle of the top plate 1 in the non-protruding area between the first guide area and the second guide area.

[0037] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: the support unit forms a double anchoring mechanism by being inserted into the ground and anchored by fixing screws, ensuring a tight connection between the tactile paving and the ground, eliminating the risk of loosening or displacement during long-term use. The galvanized layer and concrete filling further block moisture and salt corrosion, significantly extending service life and reducing maintenance frequency.

[0038] The differentiated tactile design using strip-shaped and circular guide protrusions accurately distinguishes the direction of travel from danger warning areas, improving path recognition efficiency for visually impaired individuals. Combined with the coordinated audio-visual prompts of sensor lights and speakers, it automatically triggers lighting and voice warnings in low-visibility environments such as nighttime, rain, and fog, forming a multi-dimensional guidance system that integrates touch, vision, and hearing, significantly reducing the risk of accidents.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
