Description

Technical Field

[0002] The technological development of road side anti-collision structures has gone through a process from simple to complex, and from single to multiple. In the early days, anti-collision guardrails were mostly made of wood or stone materials, with limited anti-collision performance and high maintenance costs. With the advancement of materials science and engineering technology, new anti-collision structures such as metal guardrails, concrete guardrails and composite guardrails have gradually emerged.

[0003] Existing guardrails, such as corrugated guardrails and concrete guardrails, can prevent vehicles from running off the road to a certain extent. However, their design often focuses on rigidity and strength, ignoring the energy absorption and cushioning capabilities during the impact. When a vehicle hits the guardrail at a high speed, due to the lack of sufficient cushioning mechanism, the guardrail itself may suffer serious damage. At the same time, the vehicle and passengers will also be subjected to huge impact forces, leading to serious consequences. Therefore, we need to propose a road side collision avoidance structure. Utility Model Content

[0004] The purpose of the utility model is to provide a road side collision avoidance structure, which aims to solve the problem that the road side collision avoidance structure in the prior art ignores the energy absorption and buffering capacity during the collision process. When a vehicle hits the guardrail at a high speed, due to the lack of sufficient buffering mechanism, the guardrail itself may suffer serious damage, and the vehicle and passengers will also be subjected to huge impact force, leading to serious consequences.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 , the utility model provides a technical solution:

[0024] A road side anti-collision structure includes a corrugated guardrail 1. The corrugated guardrail 1 is made of high-quality steel plates with anti-corrosion treatment, and has the characteristics of anti-aging and beautiful appearance. While ensuring safety, it can also improve the overall aesthetics of the road. One side wall of the corrugated guardrail 1 is fixedly connected with several groups of fixed blocks 2 at equal intervals. The bottoms of several groups of fixed blocks 2 are respectively provided with supporting plates 3. Two groups of through grooves 4 are respectively opened on one side wall of several groups of supporting plates 3. The insides of the two groups of through grooves 4 are respectively embedded with buffer components 5 for absorbing the impact force received by the corrugated guardrail. One end of the buffer component 5 is connected to the fixed block 2. The bottoms of several groups of supporting plates 3 are respectively fixedly connected with support rods 6. By setting the corrugated guardrail 1 , fixed block 2, supporting plate 3, through slot 4, buffer assembly 5 and support rod 6 are used in coordination. The corrugated guardrail 1 serves as the main anti-collision structure and has good collision resistance and energy absorption. When a vehicle collides, the corrugated guardrail 1 can absorb the collision energy through its own deformation, thereby reducing the impact on the vehicle and passengers. The buffer assembly 5 further enhances the buffering performance of the anti-collision structure. During the collision, the buffer assembly can absorb part of the collision energy and reduce the degree of damage to the guardrail and the vehicle. The utility model can adapt to a variety of road conditions, including mountainous areas, plains, cities, etc. By adjusting the parameters such as the height, length and spacing of the corrugated guardrail 1, the safety requirements of different road sections can be met.

[0025] In this embodiment, if Figure 5As shown, the buffer assembly 5 includes a fixed sleeve 501, which is fixedly embedded in the interior of the through groove 4. An energy-absorbing rod 502 is slidably inserted into the interior of the fixed sleeve 501, and one end of the energy-absorbing rod 502 is fixedly connected to one side of the fixed block 2. The components such as the corrugated guardrail 1, the fixed block 2, and the supporting plate 3 adopt a modular design, which is easy to install and disassemble. This design can reduce installation and maintenance costs and improve construction efficiency.

[0026] The structure further includes a buffer spring 503, one end of which is fixedly connected to the inner wall of the fixed sleeve 501, and the other end of the buffer spring 503 is fixedly connected to one end of the energy-absorbing rod 502. The fixed sleeve 501, the energy-absorbing rod 502, and the buffer spring 503 are used in conjunction with each other to further enhance the buffering performance of the anti-collision structure. During a collision, the structure can absorb part of the collision energy, thereby reducing the damage to the anti-collision structure and the vehicle.

[0027] Further, such as Figure 5 As shown, one end of the energy-absorbing rod 502 is fixedly connected to a protrusion 7, and a pressure sensor 8 is fixedly connected to the inner wall of one side of the fixed sleeve 501. One side of the protrusion 7 abuts against the pressure sensor 8. The pressure sensor 8 is cleverly integrated into the anti-collision structure on the side of the road. Once the anti-collision structure is subjected to any form of impact, the sensor can immediately capture the pressure change at this moment. This real-time monitoring capability enables the control center to obtain relevant information about the impact event in the first time, including the impact force, location and possible impact range. After receiving the data from the pressure sensor 8, the control center will immediately perform accurate analysis and processing. This data can not only help the control center determine the severity of the impact, but also predict possible consequences, such as vehicle damage, casualties, etc. Through this accurate data analysis, the control center can respond quickly and initiate corresponding emergency plans.

[0028] Further, such as Figure 4 As shown, two groups of limit blocks 9 are fixedly connected to the top of the supporting plate 3, and two groups of slide grooves 10 adapted to the limit blocks 9 are opened at the bottom of the fixed block 2. The two groups of limit blocks 9 are slidably connected to the inside of the two groups of slide grooves 10 respectively. By setting the limit blocks 9 and the slide grooves 10 in coordination, the fixed block 2 is limited.

[0029] In a further preferred embodiment, Figure 4 As shown, an energy-absorbing pad 11 is fixedly connected to one side wall of the supporting plate 3, and one side wall of the fixing block 2 abuts against the energy-absorbing pad 11. By providing the energy-absorbing pad 11, the energy-absorbing pad 11 is generally made of foam material, rubber material or other high-energy-absorbing material. These materials can deform when a vehicle collides, thereby absorbing the kinetic energy of the vehicle. This design can significantly reduce the impact force of the vehicle during a collision, reducing damage to the road side structure and the vehicle.

[0030] In addition, if Figure 3 As shown, the bottom end of the support rod 6 is fixedly connected to a fixing seat 12, and four groups of positioning holes 13 are symmetrically opened on the top of the fixing seat 12. Positioning nails 14 are respectively inserted into the inside of the four groups of positioning holes 13. By setting the fixing seat 12, the positioning holes 13 and the positioning nails 14, the fixing seat 12 serves as the basic supporting component of the anti-collision structure, which can ensure the close connection between the support rod 6 and the road side structure. The coordinated use of the positioning holes 13 and the positioning nails 14 further enhances the connection strength between the fixing seat 12, the support rod 6 and the anti-collision structure body, thereby avoiding the failure of the anti-collision structure due to loose connection.

[0031] It is worth noting that if Figure 1 As shown, it also includes a guardrail contour marker 15, which is fixedly connected to one side wall of the corrugated guardrail 1. The guardrail contour marker 15 provides the driver with a clear driving boundary indication at night or under conditions of poor visibility through its retroreflective performance. It is mainly used to provide the driver with a clear driving boundary indication to ensure that the driver can accurately judge the road boundary when driving at high speed, thereby maintaining safe driving. As a warning sign of the road lane boundary, the guardrail contour marker 15 can alert the driver to pay attention to the road boundary, thereby reducing the risk of traffic accidents.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
