Description

Technical Field

[0001] This utility model relates to the field of highway infrastructure technology, and in particular to a variable-angle intersection anti-collision pad structure. Background Technology

[0002] A crash barrier is a safety device installed at traffic intersections or road junctions, primarily used to prevent vehicle collisions, especially in the event of a traffic accident, acting as a buffer and absorbing energy. Its design aims to reduce the impact force of a vehicle collision, thereby effectively reducing personal injury and property damage in traffic accidents. Crash barriers typically consist of multiple energy-absorbing structures and connecting components, capable of absorbing a portion of the impact force during a vehicle collision, protecting the safety of drivers, passengers, and road infrastructure.

[0003] Existing intersection crash barriers typically use fixed-angle connecting components, and the angle of the crash barrier is usually preset based on the fixed structure and size of the intersection. However, intersections vary greatly in their actual conditions, with different intersections having different intersection angles. Traditional crash barriers cannot adapt to these varying angles. Due to the variability in intersection shapes, existing crash barriers cannot meet the needs of different intersection angles, resulting in an inability to maximize crash protection. Furthermore, installation requires adjustment of the crash barrier according to the specific angle, increasing installation complexity and cost.

[0004] Therefore, there is an urgent need for a variable-angle intersection crash pad structure that is no longer limited by a fixed angle during installation. This allows the energy-absorbing components to be adjusted according to the intersection angles of different intersections, ensuring that the energy-absorbing end can always match the angle of the guardrail and achieve the ideal crash protection effect.

[0028] like Figures 1 to 4 The variable-angle intersection crash barrier structure shown includes: a connecting component 1 and an energy-absorbing component 2. The connecting component 1 is horizontally positioned at the intersection of two converging guardrail sections; the energy-absorbing component 2 is positioned on the side of the connecting component 1 relatively away from the road. The connecting component 1 has a bending connector 11 and a connecting guardrail plate 12. The bending connector 11 connects the connecting guardrail plate 12 and the energy-absorbing component 2. The connecting guardrail plate 12 is installed at the end of the original guardrail. The bending connector 11 is configured to bend at an angle adapted to the intersection angle of the original guardrail. Figure 1 and Figure 2 As shown, the connecting component 1 is horizontally positioned at the intersection of two converging guardrail sections, specifically at the corner where the two guardrails meet. It is used to secure the energy-absorbing component 2 to the guardrail system. The connecting component 1 includes a bending connector 11 and a connecting guardrail plate 12. The connecting guardrail plate 12 is installed at the end of the existing guardrail and extends and connects to the energy-absorbing component 2. The bending connector 11 connects the connecting guardrail plate 12 and the energy-absorbing component 2. It is designed to bend at an angle appropriate to the intersection angle of the original guardrail, thus achieving adaptability of this crash pad structure at intersections with different angles. The energy-absorbing component 2 is positioned on the side of the connecting component 1 furthest from the road, i.e., closer to the outside. Its primary function is to absorb impact energy during a vehicle collision, providing cushioning protection.

[0029] In the above embodiments, the present invention adjusts the bending connector 11 according to the intersection angle of different intersections to ensure that the energy-absorbing component 2 can always be adapted to the angle of the guardrail, providing an ideal anti-collision effect. Compared with the prior art, it can flexibly adapt to the needs of different intersections, and simplifies maintenance and installation work while ensuring safety.

[0030] In an embodiment of this utility model, the energy-absorbing component 2 has an energy-absorbing end 21, which includes an end plate 211 and an energy-absorbing box 212. The end plate 211 is arc-shaped, connecting two sections of the guardrail plate 12. Figure 1 and Figure 2 As shown, the end plate 211 has an arc-shaped structure and is used to connect two sections of the connecting guardrail 12. The energy-absorbing box 212 is connected to the end plate 211 and is used to absorb energy during a vehicle collision. The arc-shaped structure of the end plate 211 allows it to form a natural transition between the two guardrail sections at intersecting angles, not only connecting the two sections of the connecting guardrail 12 but also helping to guide the vehicle's slippage after impact, structurally guiding the collision direction and reducing blind spots. The energy-absorbing box 212, as a specific energy-absorbing element, absorbs impact force during a collision through material deformation and structural compression. It should be noted that the energy-absorbing box 212 can be made of metal materials such as aluminum alloy, or polymer / plastic materials such as polypropylene or EPP foam, etc., depending on the usage requirements of different roads. In this embodiment, the arc-shaped end plate 211 makes the connection between the two sections of the connecting guardrail 12 smoother and avoids the safety hazards caused by sharp corners or hard bends, which is beneficial to the structural aesthetics and traffic guidance.

[0031] In an embodiment of this utility model, the energy-absorbing box 212 is disposed on the inner arc of the end plate 211. Please continue to refer to... Figure 1 and Figure 2The energy-absorbing box 212 is installed within the concave area enclosed by the arc-shaped structure. This arrangement forms an embedded energy-absorbing structure layout that neither protrudes from the outside of the structure nor obstructs the vehicle's normal driving route or visual identification. In this embodiment, the energy-absorbing box 212 is covered and protected by the end plate 211, effectively preventing it from being eroded by wind and rain or mechanically damaged during use, extending its service life, and improving the impact resistance and deformation resistance of the overall structure of the energy-absorbing end plate 21.

[0032] Furthermore, the energy-absorbing assembly 2 also includes an energy-absorbing box 22, which is installed on the side of the energy-absorbing box 212 away from the end plate 211. Please refer to [link / reference needed]. Figure 1 and Figure 2 The energy-absorbing box 22 is installed on the side of the energy-absorbing box 212 away from the end plate 211, forming a sequential arrangement structure of a front energy-absorbing box 212 and a rear energy-absorbing box 22. The energy-absorbing box 212 and the energy-absorbing box 22 are connected in series to respond sequentially to the impact force from the collision. The energy-absorbing box 22 can be configured as a closed or semi-closed structure, and its interior can be designed with energy absorption units such as honeycomb, corrugated, or collapsible structures to further bear and disperse the remaining energy that is not completely absorbed by the energy-absorbing box 212. It should be noted that the material selection for the energy-absorbing box 22 can be the same as described above, and will not be repeated here. In this embodiment, the energy-absorbing box 22 is located at the end of the energy absorption path, and can continue to bear the residual energy after the energy-absorbing box 212 has completed its initial deformation, realizing the gradual release of impact energy and reducing the peak instantaneous force on the occupants.

[0033] Furthermore, a positioning frame 23 is also provided at the end of the installation stroke of the energy-absorbing box 22, and the positioning frame 23 is connected to the connecting guardrail plate 12 by a bent connector 11. Figure 2 and Figure 3 As shown, the positioning frame 23 is located at the end of the installation stroke of the energy-absorbing box 22, that is, at the end position of the movement path of the energy-absorbing box 22. It serves to limit the deformation or sliding limit position of the energy-absorbing box 22 and constrains the movement boundary of the energy-absorbing device. The positioning frame 23 is connected to the connecting guardrail plate 12 through the bending connector 11 to form a complete fixed support system. The bending connector 11 not only realizes the angle adaptation function, but also undertakes the structural connection function of the positioning frame 23. In this embodiment, by setting the positioning frame 23 at the end of the stroke of the energy-absorbing box 22 and connecting it to the connecting guardrail plate 12 through the bending connector 11, the remaining impact force is effectively dispersed and transmitted to the road guardrail foundation during impact, avoiding localized concentrated force that could cause structural damage.

[0034] In an embodiment of this utility model, the connecting component 1 further includes a support member 13 and a plurality of fixing members 14. The support member 13 is disposed at the bottom of the energy-absorbing component 2, and the fixing members 14 fix the energy-absorbing component 2 to the support member 13. Figure 3 and Figure 4As shown, the support member 13 is located at the bottom of the energy-absorbing component 2, serving to support the weight of the energy-absorbing component 2 and maintain structural stability. Multiple fasteners 14 fix the energy-absorbing component 2 to the support member 13, using bolts or rivets for connection, ensuring that the energy-absorbing component 2 will not detach or slip when subjected to impact. In this embodiment, the multiple fasteners 14 provide multi-point positioning constraints, ensuring that the energy-absorbing component 2 maintains its installation position even under environmental vibration or continuous impact during use, ensuring that the anti-collision pad is always in the correct working state.

[0035] Furthermore, the support member 13 is horizontally positioned, and the fixing member 14 is vertically positioned. The bottom end of the fixing member 14 has a connecting hole 141, into which the support member 13 passes. For example... Figure 4 As shown, the support member 13 is horizontally positioned and can be made of steel beams, channel steel structures, or pipe columns. The bottom end of the fixing member 14 has a connecting hole 141, i.e., a through hole or sleeve hole is opened at the end of the vertical structure. During installation, the support member 13 is inserted into the connecting hole 141 at the bottom of the fixing member 14. The fixing member 14 securely positions the energy-absorbing component 2 onto the support member 13, while the support member 13 provides a lateral support foundation. Installation can also be achieved using bolts, clips, or other methods to reinforce the structure. In this embodiment, the plug-in design reduces cumbersome alignment operations; simply align the fixing member 14 with the connecting hole 141 and insert it into the support member 13. This greatly improves the speed and accuracy of construction and installation, facilitating large-scale rapid deployment.

[0036] In this embodiment of the invention, the connecting guardrail plate 12 is a corrugated guardrail plate. The guardrail plate has a continuous wavy undulating structure along the longitudinal direction, and can be configured as a double-wave or triple-wave structure. The corrugated structure itself has a certain degree of elasticity and deformation capacity, and can undergo controllable deformation after being subjected to force to absorb energy. In this embodiment, the corrugated guardrail is highly versatile in road traffic, easy to procure, and convenient for engineering construction and subsequent maintenance management.

[0037] In an embodiment of this utility model, the bent connector 11 is provided with reinforcing ribs 111. For example... Figure 3 As shown, the reinforcing rib 111 enhances the ability of the bending connector 11 to resist deformations such as bending, tension, compression, and torsion, making it less prone to breakage, excessive bending, or instability under severe impact, thus improving the structural rigidity of the bending connector 11.
