Technical Field

[0001] This utility model relates to the field of barrier-free building facilities technology, and in particular to a tactile paving brick with haptic feedback function. Background Technology

[0002] Tactile paving is a road facility designed to facilitate safe travel for the blind. Current tactile paving typically consists of ordinary square bricks with raised dots. When the soles of a blind person's shoes are thick, it can affect the tactile sensation of stepping on the raised dots. Therefore, there is a need to provide a new type of tactile paving that enhances the tactile sensation for the blind. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a tactile paving brick with haptic feedback function, including a brick, a supporting shell, an elastic element, and a base. The supporting shell supports the brick at its upper end and is positioned above the base. The elastic element is positioned between the supporting shell and the base. A limiting structure is provided between the supporting shell and the base to restrict the vertical movement of the supporting shell and the base.

[0005] Preferably, a steel back plate is provided between the facing brick and the supporting shell.

[0006] Preferably, the facing bricks and the steel back plate are bonded together with adhesive, and the supporting shell is welded to the steel back plate.

[0007] Preferably, the upper surface of the brick has raised protrusions.

[0008] Preferably, the supporting shell is a square shape with a hollowed-out top.

[0009] Preferably, the four side walls of the supporting shell are provided with limit grooves, and the base is provided with limit blocks corresponding to the limit grooves.

[0010] Preferably, the elastic element is composed of an inverted trapezoidal structure consisting of a long plate, two inclined plates, and two short plates. Inclined plates are connected to both sides of the long plate, and short plates are connected to the outer ends of the inclined plates. The midpoint of the long plate is connected to the midpoint of the bottom of the base, and the two short plates are in contact with the two ends of the upper surface inside the supporting shell.

[0011] Preferably, the elastic element is made of metal.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model uses components such as a steel back plate and a supporting shell, which are connected by welding and slots to form a stable whole, ensuring uniform stress distribution and structural stability. When subjected to a certain force, this utility model can slowly sink, and this tactile feedback can help blind people better perceive the tactile paving and improve its warning effect. This utility model is compatible with national standards and can adapt to the usage needs of different environments and scenarios, and has high versatility and practicality.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 , 2 As shown, this embodiment provides a tactile paving brick with haptic feedback function, which is installed at the tactile paving and includes a facing brick 1, a steel back plate 2, a supporting shell 3, an elastic element 4, and a base 5. The supporting shell 3 supports the facing brick 1 at its upper end and is located above the base 5. The elastic element 4 is located between the supporting shell 3 and the base 5. A limit structure is provided between the supporting shell 3 and the base 5.

[0023] The upper surface of the paving brick 1 is provided with protrusions so that blind people can perceive the existence of the tactile paving through touch. The paving brick 1 meets the relevant specifications and daily use requirements of the tactile paving.

[0024] The steel back plate 2 is set between the face brick 1 and the supporting shell 3. The steel back plate 2 has strong hardness and ductility. The face brick 1 and the steel back plate 2 are bonded together with special adhesive to ensure that the face brick 1 is subjected to uniform force in daily use and to ensure the durability requirements of the face brick 1. The supporting shell 3 is welded to the steel back plate 2.

[0025] The upper end of the supporting shell 3 supports the facing brick 1 and the steel back plate 2, and the lower end is attached to the elastic element 4. The supporting shell 3 is a square with a hollow top, and its four side walls are provided with limit grooves. The side walls of the base 5 are provided with limit blocks. The limit blocks and limit grooves cooperate to make the supporting shell 3 and the base 5 form a whole and realize the up and down movement of the supporting shell 3 and the base 5.

[0026] The elastic element 4 is set on the base 5. The elastic element 4 has strong elasticity and can be reused. The elastic element 4 is composed of an inverted trapezoidal structure consisting of a long plate, two inclined plates and two short plates. Inclined plates are connected to both sides of the long plate, and short plates are connected to the outer ends of the inclined plates. The midpoint of the long plate is connected to the midpoint of the bottom of the base 5 by bolts. The two short plates are in contact with the two ends of the upper surface inside the supporting shell 3.

[0027] In this embodiment, the supporting shell 3 is an angle steel, the elastic element 4 is a strong metal spring sheet, and the base 5 is a spring sheet box.

[0028] Working principle: The facing brick 1 receives external pressure from pedestrians. The steel back plate 2 is the internal skeleton of the facing brick, ensuring that the facing brick 1 is subjected to uniform force. The supporting shell 3 is the side maintenance structure, which forms a limiting relationship with the base 5 through the limiting groove to ensure the integrity of the structure. Figure 4 , 6 As shown, when a pedestrian steps on the tactile paving brick 1, the elastic element 4 causes the tactile paving brick to slowly sink a certain distance when subjected to a certain force. In this embodiment, the tactile paving brick can slowly sink 3-5 mm when subjected to a force of more than 45 kg. When stepped on, the limiting block moves downward within the limiting groove, ensuring the safe passage of pedestrians while providing a stronger tactile warning effect compared to ordinary tactile paving; Figure 3 , 5 As shown, when no force is applied, the elastic element 4 returns to its original shape, and when it returns to its original shape, the limiting block moves upward within the limiting groove.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
