Description

Technical Field

[0001] This utility model relates to the technical field of road traffic safety facilities, and more specifically to a reinforced anti-torsion and anti-collision pad and its high-speed anti-collision guardrail. Background Technology

[0002] In the field of highway traffic safety facilities, directional crash pads are a key protective device, primarily used to absorb the enormous kinetic energy generated by a vehicle during a collision, providing cushioning for the vehicle and its occupants and mitigating impact injuries. However, existing crash pad technology has some limitations.

[0003] Most common crash barriers currently use a corrugated plate structure. This structure is prone to twisting, wrinkling, and warping during high-speed vehicle impacts. These problems not only compromise the overall structural integrity of the crash barrier but also prevent the energy-absorbing components from deforming as intended, reducing their energy absorption efficiency. Especially in the lowermost trough section of the corrugated plate, the lack of sufficient support and reinforcement makes it more susceptible to twisting and deformation under external forces, thus affecting the performance of the entire crash barrier system.

[0004] In addition, existing crash barriers are poorly adaptable to non-frontal or oblique impacts, making it difficult to effectively guide vehicles and disperse impact forces, thus increasing the risk of vehicle loss of control and secondary accidents.

[0005] In summary, existing highway crash barriers are insufficient in terms of structural stability and energy absorption, failing to meet national requirements for highway crash barrier data and the urgent needs of actual highway traffic safety. Therefore, the development of a highway crash barrier and its associated highway crash guardrail that can effectively prevent torsional deformation and enhance structural stability and energy absorption is particularly urgent. Utility Model Content

[0006] In view of this, the present invention provides a reinforced anti-torsion and anti-collision pad and its high-speed anti-collision guardrail, aiming to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A reinforced anti-torsion anti-collision pad includes an anti-collision pad body, wherein the anti-collision pad body has a corrugated plate structure, and one side surface of the anti-collision pad body is the front-facing surface and the other side surface is the rear-facing surface.

[0009] The frontal surface of the anti-collision pad body is formed with multiple sets of crests and troughs from top to bottom. The bottom edge of the lowest trough has an extended anti-twist extension rib, which is offset from the plane where the trough is located.

[0010] Through the above technical solution, this utility model significantly enhances the structural strength of the lowermost trough section of the anti-collision pad by setting an extended anti-twist rib along the bottom edge of the trough section, which is offset from the plane of the trough section. This effectively prevents the trough section from twisting, wrinkling, or other failure phenomena when subjected to external impact, improving the service life and reliability of the anti-collision pad and ensuring that the entire anti-collision system maintains a stable energy absorption effect under different collision conditions and environments.

[0011] Preferably, in the aforementioned reinforced anti-torsion crash pad, a circular connecting hole is provided at the end of the trough section of the crash pad body near the impact end, and a strip-shaped connecting hole is provided at the end of the trough section away from the impact end. Both the circular and strip-shaped connecting holes are used to connect puncture energy dissipation bolts. The circular connecting hole near the impact end and the strip-shaped connecting hole away from the impact end provide an initial fixing point and sliding space for the puncture energy dissipation bolts, respectively. In the initial stage of the collision, the puncture energy dissipation bolt in the circular connecting hole can respond quickly and begin to puncture and absorb energy; the strip-shaped connecting hole allows the puncture energy dissipation bolt to slide and adjust its position within a certain range, providing initial power and improving the adaptability and energy absorption effect of the crash pad during the collision process.

[0012] Preferably, in the aforementioned reinforced anti-torsion crash pad, the trough section of the crash pad body has a protrusion at one end away from the impact end of the crash pad body, and the protrusion is located behind the strip-shaped connecting hole. The protrusion, located behind the strip-shaped connecting hole, provides a limiting function when multiple crash pad bodies are connected, preventing excessive displacement or misalignment of the crash pad during a collision, ensuring the stability and reliability of the overall structure of the crash pad, and helping to maintain its designed energy absorption performance and guiding function.

[0013] Preferably, in the aforementioned reinforced anti-torsion crash pad, the frontal surface of the crash pad body has three sets of crest segments and trough segments formed sequentially from top to bottom. The formation of multiple sets of crest segments and trough segments sequentially from top to bottom on the frontal surface of the crash pad body increases the energy absorption area and energy absorption path, improves the crash pad's ability to absorb vehicle kinetic energy, allows energy to be more evenly distributed and absorbed, avoids localized stress concentration, and enhances the overall energy absorption effect and stability.

[0014] Preferably, in the aforementioned reinforced anti-torsion crash pad, energy-absorbing holes are provided on the trough sections below each set of wave crests in the crash pad body. The presence of energy-absorbing holes on the trough sections below each set of wave crests increases the number of energy-absorbing points, allowing energy to be more evenly distributed and absorbed during a collision, further improving the energy absorption effect of the crash pad.

[0015] Preferably, in the aforementioned reinforced anti-torsion impact pad, the energy-absorbing hole is an isosceles triangular hole, with the apex of the isosceles triangular hole facing the impact end of the impact pad body. The isosceles triangular shape of the energy-absorbing hole, with the apex facing the impact end, facilitates the guidance and dispersion of impact force, allowing it to be transmitted and absorbed along a specific path. This shape design more effectively guides the energy-dissipating bolts to break through, promoting the deformation of the energy-absorbing component according to a predetermined pattern, improving energy absorption efficiency, while maintaining the stability and integrity of the structure.

[0016] This utility model also provides a high-speed crash barrier, including:

[0017] Base slide;

[0018] A sliding mounting bracket, wherein there are multiple sliding mounting brackets, and the multiple sliding mounting brackets are slidably connected to the base slide, and the aforementioned reinforced anti-torsion and anti-collision pads are connected to both sides of two adjacent sliding mounting brackets.

[0019] Through the above technical solution, multiple sliding mounting brackets of this utility model are slidably connected to the base slide block, and reinforced anti-torsion anti-collision pads are connected between adjacent sliding mounting brackets, so that the anti-collision pads can slide along the base slide block during the collision, realize energy absorption in stages, buffer the impact force of the vehicle, reduce the reaction force on the vehicle, improve the adaptability to different types and speeds of vehicles, and enhance the protection effect.

[0020] Preferably, in the above-mentioned high-speed crash barrier, the base slide includes a base mounting frame and two sliding rods fixed parallel to each other between the base mounting frame. The bottom of the sliding mounting frame has a sliding sleeve that is slidably connected to the sliding rods. The base slide consists of a base mounting frame and two sliding rods. The sliding mounting frame is slidably connected to the sliding rods through the sliding sleeve. The structure is simple and stable, providing good support and guidance for the sliding mounting frame and the crash barrier, ensuring smooth sliding of the crash barrier during a collision, which is conducive to achieving step-by-step energy absorption through perforation, and is also easy to install and maintain.

[0021] Preferably, in the aforementioned high-speed crash barrier, bolt connection holes are provided on both side walls of the sliding mounting bracket. These bolt connection holes are used to connect and engage with the energy-absorbing bolts to fix the crash barrier body. The bolt connection holes on the sliding mounting bracket, in conjunction with the energy-absorbing bolts, enable quick and reliable fixing of the crash barrier body. Installation is convenient, ensuring the stability of the crash barrier during a collision and ensuring that the energy-absorbing bolts accurately act on the energy-absorbing holes, achieving effective energy absorption through puncture.

[0022] Preferably, in the aforementioned high-speed crash barrier, an arc-shaped outer impact plate is fixed to the front end of the sliding mounting bracket near the impact end of the base slide. The arc-shaped outer impact plate fixed to the front end of the sliding mounting bracket near the impact end of the base slide can initially guide and buffer the vehicle, allowing the vehicle to make more stable contact with the crash barrier upon impact, avoiding excessive impact force on certain parts of the vehicle, reducing vehicle damage and occupant injury, and simultaneously guiding the vehicle to slide in a predetermined direction, improving the overall protective performance and reliability of the crash barrier.

[0023] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a reinforced anti-torsion crash pad and its high-speed crash barrier. By setting anti-torsion extension ribs with staggered planes along the bottom edge of the lowest trough section of the crash pad body, the structural strength of the trough section is effectively enhanced, preventing torsional deformation and overall upward warping, thus improving the stability and service life of the crash pad. Simultaneously, the design of multiple crest and trough sections, along with the optimized layout of isosceles triangular energy-absorbing holes, allows the crash pad to more evenly disperse and absorb energy during a collision, significantly improving the energy absorption effect. Furthermore, the cooperation between the sliding mounting bracket and the base slide seat achieves step-by-step energy absorption, reducing the impact force on the vehicle and enhancing the protective effect. Overall, this patent effectively solves the problems of poor structural stability and insufficient energy absorption effect of existing crash pads, providing a more reliable protection solution for highway traffic safety.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Example 1:

[0043] See appendix Figure 1 To be continued Figure 2 This utility model embodiment discloses a reinforced anti-torsion anti-collision pad, including an anti-collision pad body 3, the anti-collision pad body 3 is a corrugated plate structure, and one side surface of the anti-collision pad body 3 is the front-facing surface 31, and the other side surface is the rear-facing surface 32.

[0044] The frontal surface 31 of the anti-collision pad body 3 is formed with multiple sets of crest sections 33 and trough sections 34 from top to bottom. The bottom edge of the lowest trough section 34 has an extended anti-torsion extension rib 35, which is offset from the plane where the trough section 34 is located.

[0045] To further optimize the above technical solution, a circular connecting hole 342 is provided at the end of the trough section 34 of the anti-collision pad body 3 near the impact end of the anti-collision pad body 3, and a strip-shaped connecting hole 343 is provided at the end of the trough section 34 of the anti-collision pad body 3 away from the impact end of the anti-collision pad body 3. Both the circular connecting hole 342 and the strip-shaped connecting hole 343 are used to connect the puncture energy dissipation bolt 4. The design of the strip-shaped connecting hole 343 is to allow the puncture energy dissipation bolt 4 to have a certain acceleration space during puncture, so that there are no other obstacles within the strip-shaped connecting hole 343, and it can quickly accumulate puncture force.

[0046] To further optimize the above technical solution, the trough section 34 of the anti-collision pad body 3 has a protrusion 344 at the end away from the impact end of the anti-collision pad body 3. The protrusion 344 is located behind the strip-shaped connecting hole 343. The protrusion 344 is to provide a limiting function when multiple anti-collision pad bodies 3 are connected.

[0047] In this embodiment, the frontal surface 31 of the anti-collision pad body 3 is formed with three sets of crest sections 33 and trough sections 34 from top to bottom.

[0048] In this embodiment, the anti-torsion extension rib 35 can improve the structural strength of the lowest trough section 34. In practical applications, one of the reasons for designing a corrugated plate structure is that the trough section 34 has crest sections 33 above and below it, which provides a reinforced structure for the trough section 34. However, in Embodiment 1, the lowest trough section 34 is only reinforced by the upper crest section 33. Therefore, the bottom edge of the lowest trough section 34 is easily twisted and wrinkled under the impact of external force, causing failure. Therefore, in order to solve this problem and save material costs, the bottom edge of the lowest trough section 34 has an extended anti-torsion extension rib 35 to improve the structural strength.

[0049] In this embodiment, the anti-torsion extension stiffener 35 is arranged at the bottom edge of the bottom edge of the vertical trough section 34. In fact, in other embodiments, it can be any shape, such as arc, curled, or non-perpendicular but forming an angle, as long as it can improve the structural strength.

[0050] Example 2:

[0051] See appendix Figure 3 and attached Figure 4 This embodiment is a further improvement on embodiment 1. Energy-absorbing holes 341 are provided on the trough section 34 below each set of crest sections 33 of the anti-collision pad body 3.

[0052] In this embodiment, the energy-absorbing hole 341 is an isosceles triangular hole, and the apex of the isosceles triangular hole faces the impact end of the anti-collision pad body 3.

[0053] Example 3:

[0054] See appendix Figure 5 and attached Figure 6 This utility model discloses a high-speed crash barrier, comprising:

[0055] Base slide 1;

[0056] There are multiple sliding mounting brackets 2, which are slidably connected to the base slide block 1. Both sides of two adjacent sliding mounting brackets 2 are connected to the three-layer perforated energy-absorbing anti-collision pads of embodiment 2.

[0057] To further optimize the above technical solution, the base slide 1 includes a base mounting frame 11 and two slide rods 12 that are fixed in parallel between the base mounting frame 11. The bottom of the sliding mounting frame 2 has a sliding sleeve 21 that is slidably connected to the slide rods 12.

[0058] To further optimize the above technical solution, bolt connection holes 22 are provided on both sides of the sliding mounting bracket 2. The bolt connection holes 22 are used to connect and cooperate with the energy dissipation bolts 4 to fix the anti-collision pad body 3.

[0059] To further optimize the above technical solution, the energy-absorbing hole 341 is an isosceles triangular hole, and the apex angle of the isosceles triangular hole faces the impact end of the anti-collision pad body 3; the apex angle of the isosceles triangular holes on the multiple anti-collision pad bodies 3 arranged sequentially from one end of the base slide block 1 near its impact end to the other end gradually increases.

[0060] To further optimize the above technical solution, an arc-shaped outer impact plate 5 is fixed to the front end of the sliding mounting bracket 2 near the impact end of the base slide 1.

[0061] Example 4:

[0062] See appendix Figure 7 The only difference between this embodiment and embodiment 3 is the overall length. This embodiment is longer than embodiment 3 and is suitable for highways with higher speed limits.

[0063] Taking the structure of this embodiment as an example, the impact principle of this embodiment is as follows:

[0064] The car first impacts the curved outer impact plate 5, then pushes the foremost sliding mounting bracket 2 to begin sliding backward. The energy-dissipating bolt 4 on the second sliding mounting bracket 2 begins to puncture the energy-absorbing holes 341 on the foremost anti-collision pad body 3 to dissipate energy, until the anti-collision pad body 3 is completely punctured. Since the edges of adjacent anti-collision pad bodies 3 are stacked, after the first anti-collision pad body 3 is punctured, it continues to push the second sliding mounting bracket 2 to slide. Then the energy-dissipating bolt 4 on the third sliding mounting bracket 2 punctures the second anti-collision pad body 3 to dissipate energy, and so on.

[0065] As the apex angle of the isosceles triangular holes on the multiple anti-collision pad bodies 3 arranged sequentially from one end of the base slide block 1 near its impact end to the other end gradually increases, the spacing of the same group of energy-absorbing holes 341 gradually increases, so the force required to break the hole gradually increases, realizing the stepwise progressive hole breaking and energy dissipation.

[0066] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0067] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
