Description

Technical Field

[0001] The utility model relates to the technical field of speed bumps, in particular to a road speed bump. Background Art

[0002] Speed ​​bumps, also known as speed bumps, are roadside devices designed to slow down passing vehicles. They are typically strip-shaped, but some are dotted. They are primarily made of rubber, though some are metal. They are typically yellow and black to attract attention, creating a slight arch in the road surface to slow down vehicles. They are typically installed at intersections, industrial and mining enterprises, schools, and residential areas where traffic needs to slow down and where accidents are likely to occur. They are a new type of traffic safety device designed to reduce the speed of both motor vehicles and non-motor vehicles.

[0003] Currently, speed bumps made of materials such as rubber and plastic are commonly used on Chinese roads to reduce vehicle speeds and ensure traffic safety. However, existing speed bumps generate significant noise and vibration when vehicles pass over them, causing damage to the road surface and vehicles. This also creates a poor user experience for passengers in vehicles that are already slowing down. Furthermore, these bumps have a short service life and present certain limitations.

[0025] Example 1

[0026] Currently, speed bumps made of materials such as rubber and plastic are commonly used on Chinese roads to reduce vehicle speeds and ensure traffic safety. However, existing speed bumps generate significant noise and vibration when vehicles pass over them, causing damage to the road surface and vehicles. This also creates a poor user experience for passengers in vehicles that are already slowing down. Furthermore, these bumps have a short service life and present certain limitations.

[0027] Based on this, the utility model provides a road speed bump, such as Figure 1 and Figure 2 As shown, it includes a strip-shaped speed bump body 1 and connectors 2 arranged on both long sides of the speed bump body 1. The connectors 2 are provided with a plurality of first mounting countersunk holes 3 along the length direction. Figure 2 As shown in FIG, the top surface of the speed bump body 1 is an arc-shaped surface. Figure 2 As shown, the speed bump body 1 is composed of a D3O (D3O material remains in a relaxed state under normal conditions, is soft and elastic. Once subjected to a violent impact or extrusion, the molecules immediately lock with each other, quickly tighten and harden to absorb the external force, forming a protective layer. When the external force disappears, the material will return to its original relaxed soft elastic state. It can respond differently to different impact conditions within nanoseconds) speed bump body 101 and a rubber speed bump body 102. The D3O speed bump body and the rubber speed bump body are distributed up and down. In terms of the height of the speed bump body, the D3O speed bump body accounts for 1 / 2 to 3 / 5 of the total height of the speed bump body. It is worth noting that Figure 3-5 The two materials in the speed bump body 1 are not distinguished. Furthermore, the top surface of the speed bump body 1 is provided with anti-slip grooves (not shown in the prior art). The specific formula of the D3O material in this utility model is, by volume, 15-35% PBDMS (expandable non-Newtonian fluid), 40-70% fluid (gas generated during the foaming process, typically carbon dioxide), and the remainder polyurethane.

[0028] Working Principle: First, the speed bump body 1 is laid on the road section where speed reduction is required. The speed bump body 1 is then fixed to the road surface using connectors 2. The connectors 2 can be fixed to the ground by plugging, welding, or threading. Because the top surface of the speed bump body 1 is curved, it can achieve a deceleration effect. Because the upper portion of the speed bump body 1 is the D3O speed bump body 101, it has excellent energy absorption properties and can effectively reduce the vibration and noise generated when vehicles pass over the speed bump. Furthermore, the D3O speed bump body 1 has excellent wear resistance, weather resistance, and corrosion resistance, significantly extending the service life of the speed bump and effectively reducing maintenance costs.

[0029] Example 2

[0030] In Example 1, since the fluorescent strip 502 is not provided on the speed bump, it is not safe for vehicles to pass through at night.

[0031] Based on this, on the basis of Example 1, as Figure 3-5 As shown, the speed bump body 1 (in this embodiment, it refers to the D3O speed bump body. Whether it is set on the D3O speed bump body or the rubber speed bump body in actual installation can be determined according to the situation) has multiple strip grooves 4 set on both sides of the top surface along the length direction. A fluorescent plate 5 is set in each of the strip grooves 4. By setting the fluorescent plate 5 in the strip groove 4, it can emit light at night to alert the driver in time, ensure that the driver can slow down in time, and improve driving safety. Further, as Figure 4 and Figure 5 As shown, the fluorescent plate 5 is composed of a rubber plate 501 and a fluorescent strip 502 arranged on the outside of the rubber plate 501; the top and bottom ends of the rubber plate 501 are respectively in contact with the top wall and bottom wall of the strip groove 4. Furthermore, a second mounting countersunk hole is provided on the fluorescent plate 5, and the fluorescent plate 5 and the strip groove 4 are connected by a limit screw 6 provided in the second mounting countersunk hole. The rubber plate 501 is provided with shock resistance, and can provide a certain support force and shock resistance to the strip groove 4. At the same time, in order to avoid the wheel contacting the fluorescent strip 502, resulting in a reduction in the service life of the fluorescent strip 502, in actual setting, as shown in FIG. Figure 4 and Figure 5 As shown, the fluorescent strip 502 does not protrude from the outside of the strip groove 4 but is entirely located within the strip groove 4, effectively preventing contact with the vehicle tire. Furthermore, the provision of a stop screw 6 allows for a detachable connection between the fluorescent plate 5 and the strip groove 4, allowing for immediate removal from the strip groove 4 for repair or replacement if the fluorescent plate 5 is damaged.

[0032] Example 3

[0033] In Example 2, because the top wall of the strip groove 4 is horizontal and the driver's height is higher than the strip groove 4, the top wall of the strip groove 4 will have a certain blocking effect on the upper portion of the fluorescent strip 502, resulting in partial obstruction of the light emitted by the fluorescent strip 502, which has a certain impact on the warning effect. At the same time, after the strip groove 4 blocks the upper portion of the fluorescent strip 502, it is difficult for rainwater to fully rinse the fluorescent strip 502, making it difficult to promptly remove dirt adhering to the fluorescent strip 502, affecting the luminous effect. Furthermore, because the bottom wall of the strip groove 4 is horizontal, when it rains, rainwater is difficult to drain from the bottom end of the strip groove 4 in a timely manner, resulting in the strip groove 4 being easily attracted by dust. At the same time, the humid environment also has an adverse effect on the performance of the speed bump body 1.

[0034] Based on this, on the basis of Example 2, as Figure 6 As shown, the top wall of the strip groove 4 is tilted upward toward the outside to reduce the degree of obstruction of the fluorescent strip 502 by the strip groove 4, so that the light emitted by the fluorescent strip 502 can be fully displayed, improving the warning effect and ensuring that rainwater completely washes the fluorescent strip 502. Furthermore, the bottom wall of the strip groove 4 is tilted downward toward the outside to effectively drain water and prevent rainwater from accumulating in the strip groove 4. Figure 6 As shown, the fluorescent strip 502 is tilted, so the light-emitting side of the fluorescent strip 502 can directly contact rainwater, which can wash away dust on the light-emitting side of the fluorescent strip 502. The surface of the fluorescent strip 502 and the top and bottom walls of the strip groove 4 are all provided with a hydrophobic layer 7 to ensure that rainwater on rainy days can quickly separate from the strip groove 4 after washing the fluorescent strip 502. This prevents the fluorescent strip 502 from being adhered to by rainwater, which would aggravate the accumulation of dust. This would result in excessive dust adhering to the light-emitting side of the fluorescent strip 502 after the fluorescent strip 502 dries, thus affecting the luminous effect.
