Description

Technical Field

[0001] The utility model relates to the technical field of highway speed reduction strips, in particular to a speed-limiting speed reduction strip used for rural roads. Background Art

[0002] Speed ​​bumps achieve deceleration by affecting the driver's driving psychology. When a vehicle passes over a speed bump at a high speed, violent vibrations will be transmitted from the tires through the body and seat to the driver. The vertical curve can produce a vertical acceleration, resulting in violent physiological stimulation (including vibration stimulation and visual stimulation) and psychological stimulation. Physiological stimulation causes the driver to feel strongly uncomfortable, while psychological stimulation deepens the driver's unsafe doubts and further reduces the driver's sense of security about the road environment. Generally speaking, drivers believe that the greater the discomfort, the less safe the vehicle is, that is, the less sense of security. Therefore, the setting of speed bumps will reduce the driver's expectations of driving safety and riding comfort, prompting the driver to choose a lower expected speed. Under the guidance of the expected speed, the driver will actively drive the vehicle to approach and pass the speed bump at a lower speed.

[0003] The existing rural roads have low traffic volume and serious speeding. When driving through villages and schools at too fast speed, traffic accidents are very likely to occur. It is now planned to install speed bumps on some sections where pedestrians appear frequently to reduce the probability of traffic accidents. The existing speed bumps are mainly divided into rubber speed bumps and concrete speed bumps. The advantage of concrete speed bumps is that they are built together with road construction, formed in one go, simple to construct, inexpensive, and durable. The disadvantage is that the warning effect is not obvious. The advantage of rubber speed bumps is that the setting position can be adjusted at will, the warning effect is obvious, and the installation is easy. The disadvantage is that the service life is short and the maintenance cost is high.

[0004] Rural roads are the main channels connecting villages with the outside world, and their traffic safety issues have always attracted much attention. Compared with urban roads, rural roads have complex and changeable road conditions, with many bends, narrow roads, and incomplete traffic signs, which make driving more difficult and easily lead to traffic accidents, especially at level crossings, which often become accident-prone areas due to excessive speed.

[0005] In order to reduce vehicle speed and traffic accidents, speed limit deceleration bumps are widely used on rural roads as an effective traffic safety facility. Speed ​​limit deceleration bumps force vehicles to slow down by physical means, so that drivers have more reaction time and judgment space during driving, thereby reducing the risk of accidents. Early speed limit deceleration bumps were mainly made of cement or metal materials or rubber, with fixed shapes and difficult to change after installation. Although these speed bumps have played a speed limiting role to a certain extent, they also have some problems. For example, cement speed bumps have a large wear on vehicle tires and are not easy to remove after installation, which brings difficulties to the maintenance of roads; metal speed bumps may be deformed or damaged due to vehicle collisions, and require frequent repairs or replacements; rubber speed bumps, due to the high rolling of vehicles every day, plastic is easily damaged and has a short lifespan. At the same time, the existing speed bumps are set as an integrated molding structure. After damage, they can only be replaced as a whole, and the maintenance cost is high; and the existing speed bumps play a key role in slowing down vehicles. In order to achieve a better deceleration effect, the existing speed bumps usually have multiple speed bumps set in the same place, but the stiffness is strong when the vehicle passes by, the comfort is not high, and there are problems such as large damage to the vehicle when the vehicle rolls over the speed bumps. Utility Model Content

[0006] In view of the deficiencies in the prior art, the technical problem solved by the utility model is a speed-limiting deceleration bump for rural roads, which solves the problem of high maintenance costs of the prior deceleration bumps.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is: a speed limit deceleration bump for rural roads, characterized in that: it includes a fixed seat, support seats are arranged at both ends of the fixed seat, and the support seats are connected with the fixed seat in a cooperative manner; a plurality of connecting seats are arranged at the lower end of the support seat, and the connecting seats are fixedly connected with the support seat; a supporting device is arranged on the surface of the fixed seat, and a plurality of springs are fixedly arranged on both sides of the supporting device; a rubber layer is arranged at the upper end of the support seat, and folded edges are arranged at both ends of the rubber layer, and the folded edges are connected with the support seat in a cooperative manner, and mounting grooves and mounting pieces are respectively arranged at both ends of the fixed seat, and the mounting piece is connected with the mounting groove on another fixed seat in a cooperative manner.

[0008] The beneficial effects of this solution are: through the cooperation and connection of the mounting piece and the mounting groove arranged on the fixed seat, and the connection seat and the support seat are threadedly connected by connecting bolts, the fixed seat and the support seat are cooperated and connected, so that the speed bump is spliced ​​together with multiple speed bumps, which is convenient for maintenance. During maintenance, there is no need to replace the entire speed bump, which reduces maintenance costs. The support device arranged inside the fixed seat and the springs arranged on both sides of the support device reduce the stiffness of the speed bump when the vehicle is driving, and improve the comfort when passing through the speed bump.

[0009] Furthermore, an arc-shaped structure is arranged at one end of the support seat away from the fixed seat. The arc-shaped design of the support seat can make the vehicle more stable when entering and leaving the speed bump, reduce sudden changes in direction or bumps, and thus reduce the risk of traffic accidents caused by vehicle loss of control or sideslipping; at the same time, the arc-shaped design can disperse the impact force of the vehicle on the speed bump, reduce the wear of the speed bump, and extend its service life.

[0010] Furthermore, the side of the support device close to the rubber layer is arranged in an arc-shaped structure, and the arc-shaped top of the support device can effectively disperse the impact force when the vehicle tire contacts the speed bump. This design can reduce damage to the vehicle suspension system and tires, while reducing wear on the speed bump itself and extending its service life.

[0011] Furthermore, the support seat and the fixing seat are connected by bolts, and the connection is stable and reliable, and easy to disassemble, which is convenient for subsequent maintenance. At the same time, it is highly flexible and can be installed according to different road widths.

[0012] Furthermore, the rubber layer is provided with a plurality of reflective grooves arranged in parallel, and the reflective grooves are arranged in a trapezoidal structure. The design of the trapezoidal reflective grooves can effectively collect and reflect light, especially at night or in an environment with insufficient light, and can provide better lighting effects and visual clarity. This design helps to increase the driver's perception of road conditions and improve driving safety.

[0013] Furthermore, a sunken connecting groove is provided on the rubber layer, and a fixing bolt is provided in the connecting groove and is threadedly connected to the supporting device, so that the rubber layer and the supporting device fit better, which can better reduce noise when the vehicle is rolling over and increase the service life.

[0014] Furthermore, a mounting groove is provided at one end of the fixing seat, and a mounting piece corresponding to the mounting groove is provided at the other end. The mounting piece is connected with the mounting groove to facilitate installation and fixation of the fixing seat, and is easy to disassemble and has strong flexibility.
