Description

Technical Field

[0001] This utility model relates to the field of traffic safety facilities technology, and in particular to a flexible anti-collision traffic safety facility. Background Technology

[0002] In the field of road traffic safety, crash barriers, as one of the important road infrastructures, are widely installed in key locations such as highways, urban arterial roads, bridges, tunnel entrances and exits, and accident-prone areas. They play a vital role in guiding traffic flow, isolating traffic flow, absorbing collision energy, and preventing vehicles from crossing the median or entering oncoming lanes. For example, when vehicles are traveling at high speeds on the road, collisions can occur at any time due to various unforeseen factors, such as driver negligence, sudden mechanical failures, obstructed visibility due to inclement weather, or poor road conditions. In such cases, crash barriers become the first line of defense against the spread of danger. For vehicles, crash barriers can effectively absorb and disperse impact energy when a vehicle loses control and veers toward the roadside or collides with other vehicles, reducing the extent of vehicle damage and preventing more serious situations such as rollovers or disintegration due to severe collisions. This maximizes the protection of the lives of passengers and the integrity of the vehicle.

[0003] Traditional crash barriers mainly use rigid guardrails such as concrete barriers, which are characterized by their sturdy structure and strong impact resistance, making them suitable for protection in high-risk areas. However, in practical applications, it has been found that when a vehicle collides with a rigid guardrail at a high speed, it is difficult to effectively absorb and disperse the impact energy, which can easily cause the vehicle to bounce, roll over, or even penetrate the guardrail, thus causing serious injury to the occupants. In addition, after being subjected to multiple impacts, rigid guardrails may suffer local damage or overall deformation, which is difficult and costly to repair, affecting their long-term effectiveness.

[0004] To overcome the aforementioned problems, flexible collision avoidance traffic safety facilities have been increasingly researched and applied in recent years. Flexible collision avoidance facilities are typically made of high-strength materials and possess good buffering and energy absorption properties. They can absorb some of the impact energy through deformation during a vehicle collision, thereby reducing vehicle damage and the risk of personal injury. However, in practical applications, existing flexible collision avoidance facilities still face challenges such as limited buffering and energy absorption effects, complex installation, inconvenient maintenance, and insufficient weather resistance and environmental adaptability. Their stability and reliability, especially in complex environments such as mountain curves, icy roads, or rainy areas, still need improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible anti-collision traffic safety facility to protect vehicles from serious damage as much as possible at the moment of vehicle collision, maximize the safety of people and reduce the degree of property damage.

[0006] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0007] This utility model provides a flexible anti-collision traffic safety facility, including a buffer assembly, a mounting plate, and a supporting mounting frame; the buffer assembly includes a buffer box frame and a buffer pad installed on the buffer box frame; the buffer box frame and the supporting mounting frame are respectively installed on opposite sides of the mounting plate; the side of the buffer pad facing away from the mounting plate is exposed from the buffer box frame, and honeycomb holes are formed on the buffer pad.

[0008] The embodiments of this utility model can achieve at least the following beneficial effects:

[0009] When a vehicle unfortunately collides with this flexible collision avoidance traffic safety facility, the first point of contact is the buffer pad. As the first line of defense in this flexible collision avoidance traffic safety facility, the buffer pad plays a crucial pioneering role in the entire buffer system. Thanks to its unique honeycomb structure, the buffer pad effectively reduces the impact force. When the impact force is transmitted to the buffer pad, these honeycomb holes act like tiny energy traps, causing the impact energy to be continuously reflected, dispersed, and dissipated within the holes, thus effectively reducing the impact force transmitted to the vehicle. Simultaneously, because the buffer pad is made of flexible material, which possesses excellent deformation capacity and elastic recovery characteristics, during the impact, the buffer pad can rapidly adapt its deformation according to the shape and force of the impact, acting like a soft shield to evenly distribute the impact force, avoiding serious damage caused by localized stress concentration, and greatly reducing the damage suffered by the vehicle in the initial stage of the collision.

[0010] In an optional embodiment of this example, in addition to the buffer box frame and buffer pad mentioned above, the buffer assembly is also provided with other buffer structures. When the collision force of the vehicle is large and exceeds the buffer range that the buffer pad alone can withstand, the other buffer structures inside the flexible anti-collision traffic safety facility work together to further absorb and convert the remaining impact energy of the vehicle, thereby providing comprehensive protection for the vehicle under high-intensity collisions.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] In vehicle collision scenarios, due to the combined influence of various factors, the impact force between the vehicle and the device often exhibits complex and inconsistent variations. Based on this, this embodiment provides a flexible anti-collision traffic safety facility to protect the vehicle from severe damage as much as possible at the moment of impact, maximize the safety of personnel, and reduce the degree of property damage.

[0042] Reference Figures 1 to 5The flexible collision avoidance traffic safety facility includes a buffer assembly 1, a mounting plate 2, and a supporting mounting frame 3. Specifically, the buffer assembly 1 includes a buffer box frame 11 and a buffer pad 12 mounted on the buffer box frame 11; the buffer box frame 11 and the supporting mounting frame 3 are respectively mounted on opposite sides of the mounting plate 2. The buffer pad 12 has the buffer box frame 11 exposed on the side facing away from the mounting plate 2, and honeycomb holes 121 are formed on the buffer pad 12. The buffer pad 12 is made of flexible material, and the shape, size, and arrangement of the honeycomb holes 121 are not specifically limited, but are preferably evenly distributed throughout the buffer pad 12, and the shape, size, and hole spacing are determined based on multiple mechanical analyses and tests.

[0043] When a vehicle unfortunately collides with this flexible collision avoidance traffic safety facility, the first point of contact is the buffer pad 12. As the first line of defense of this flexible collision avoidance traffic safety facility, the buffer pad 12 plays a crucial pioneering role in the entire buffer system. With its unique honeycomb hole 121 structure, the buffer pad 12 can effectively reduce the impact force. When the impact force is transmitted to the buffer pad 12, these honeycomb holes 121 act like tiny energy traps, causing the impact energy to be continuously reflected, dispersed, and consumed within the holes, thereby effectively reducing the impact force transmitted to the vehicle. At the same time, because the buffer pad 12 is made of flexible material, this flexible material has excellent deformation capacity and elastic recovery characteristics. During the impact, the buffer pad 12 can quickly adapt to the shape and force of the impact, like a soft shield, evenly dispersing the impact force of the vehicle, avoiding serious damage caused by local stress concentration, and greatly reducing the damage suffered by the vehicle in the initial stage of the collision.

[0044] like Figure 4 As shown, regarding the specific installation method of the buffer pad 12 on the buffer box frame 11, in an optional embodiment of this example, the buffer box frame 11 includes at least a perimeter frame that encloses the installation space, and one side surface of the perimeter frame is provided with an installation opening; one side of the buffer pad 12 is fixedly connected to an installation plate 13, and the buffer pad 12 is embedded into the installation space of the buffer box frame from the aforementioned installation opening, and the installation plate 13 is fixed to the part of the perimeter frame of the buffer box frame where the installation opening is provided.

[0045] This optional embodiment provides an installation space enclosed by a perimeter frame on the buffer box frame 11, with an installation opening on one side, allowing the buffer pad 12 to be directly embedded into the installation space through the installation opening. This structural design simplifies the assembly process and improves installation efficiency. When the buffer pad wears or is damaged due to long-term use, it can be quickly replaced without affecting other components, facilitating production and maintenance after deployment. Simultaneously, an installation plate 13 is fixedly connected to one side of the buffer pad 12, and this installation plate 13 is fixedly connected to the installation opening on the buffer box frame 11. This method enhances the connection strength between the buffer pad and the buffer box frame, improves the overall structural stability and impact resistance, thereby further improving the application safety and service life of this flexible anti-collision traffic safety facility after deployment.

[0046] In an optional embodiment of this invention, a reflective guide sign 4 is installed on the side of the buffer pad 12 facing away from the mounting plate 2. The reflective guide sign 4 can be glued, sewn, or otherwise installed on the surface of the buffer pad 12. Alternatively, the reflective guide sign 4 can be embedded in the installation space of the aforementioned buffer box frame 11 and pressed between the buffer pad 12 and the periphery of the buffer box frame 11. Alternatively, the periphery of the reflective guide sign 4 can be engaged in a groove provided on the inner surface of the periphery of the buffer box frame 11. Or, any other installation method can be used, as long as the reflective guide sign 4 is installed on the side of the buffer pad 12 facing away from the mounting plate 2. In this optional embodiment, by installing the reflective guide sign 4 on the side of the buffer pad 12 facing away from the mounting plate 2, the flexible anti-collision traffic safety facility can effectively guide traffic flow. Furthermore, the reflective guide sign 4 will not interfere with the rapid adaptive deformation of the buffer pad 12 according to the impact shape and force of the vehicle during the impact process, absorbing and dispersing the collision energy.

[0047] In an optional embodiment of this example, in addition to the buffer box frame 11 and the buffer pad 12, the buffer assembly 1 is also provided with other buffer structures. When the collision force of the vehicle is large and exceeds the buffer range that the buffer pad 12 can withstand alone, the other buffer structures inside the flexible anti-collision traffic safety facility work together to further absorb and convert the remaining impact energy of the vehicle, thereby ensuring that the vehicle can minimize the damage under high-intensity collisions in all aspects and providing solid and reliable protection for road traffic safety.

[0048] Specifically:

[0049] like Figures 1 to 3 As shown, in an optional embodiment of this example, the buffer assembly 1 further includes an elastic steel 52 fixedly installed between the buffer box frame 11 and the mounting plate 2; the elastic steel 52 has a concave-convex surface with multiple recesses and protrusions on one side of the buffer box frame 11 and the other side of the mounting plate 2.

[0050] It should be noted that in this optional embodiment, the "recessed portion" and "convex portion" of the "concave-convex surface" are relative to the surface of the buffer box frame 11 or the mounting plate 2 that the "concave-convex surface" faces. Specifically, when the "concave-convex surface" is the surface of the elastic steel 52 facing the buffer box frame 11, the "recessed portion" refers to the recessed part of the elastic steel 52's surface away from the buffer box frame 11, and the "convex portion" refers to the raised part of the elastic steel 52's surface facing the buffer box frame 11; when the "concave-convex surface" is the surface of the elastic steel 52 facing the mounting plate 2, the "recessed portion" refers to the recessed part of the elastic steel 52's surface away from the mounting plate 2, and the "convex portion" refers to the raised part of the elastic steel 52's surface facing the mounting plate 2. The design of the "concave" and "convex" parts of the "concave-convex surface" can be arranged regularly or irregularly. The shapes of the "concave" and "convex" parts can be the same or different. The shapes of the depressions in different "concave" parts can be the same or different, and the shapes of the protrusions in different "convex" parts can be the same or different. The main purpose of this "concave-convex surface" design is to make the elastic steel 52 more adaptable to deformation, so that after the elastic steel 52 absorbs the energy generated by the collision, it can further absorb and convert the remaining impact energy of the vehicle, thereby strengthening the buffering capacity of the buffer assembly 1.

[0051] In this optional embodiment, the surfaces of the buffer box frame 11 and the mounting plate 2 facing the elastic steel 52 respectively contact part or all of the convex surfaces of the corresponding concave-convex surface of the elastic steel 52. In this optional embodiment, the surface of the buffer box frame 11 facing the elastic steel 52 includes the surface of the perimeter frame of the buffer box frame 11 facing the elastic steel 52. In addition to the buffer box frame 11, the surface of the buffer pad 12 facing the elastic steel 52 also contacts part or all of the convex surfaces of the corresponding concave-convex surface of the elastic steel 52. Alternatively, the buffer box frame 11 may also include a back plate disposed between the buffer pad 12 and the elastic steel 52 and fixedly or integrally connected to the perimeter frame of the buffer box frame 11. The back plate and the mounting plate 2 respectively contact part or all of the convex surfaces of the corresponding concave-convex surface of the elastic steel 52. The back plate is a thin plate structure that can quickly deform with the buffer pad 12 to absorb collision energy during a collision.

[0052] Regarding the specific installation method of the elastic steel 52 between the buffer box frame 11 and the mounting plate 2, alternatively, the surfaces of the buffer box frame 11 and the mounting plate 2 facing the elastic steel 52 are respectively fixedly connected to part or all of the convex surfaces of the corresponding concave and convex surfaces of the elastic steel 52. The fixed connection method includes, but is not limited to, bonding or fixing with fasteners such as screws. The number of elastic steel 52 is not specifically limited. For example, in some optional embodiments, the elastic steel 52 extends in the left-right direction, and at least four elastic steel 52s are arranged longitudinally at intervals, so that the elastic steel 52 corresponds to the buffer pad 12 front and back as much as possible. When the buffer pad 12 is impacted, the elastic steel 52 can absorb and convert as much of the remaining impact energy of the vehicle as possible after the buffer pad 12 absorbs the energy generated by the impact.

[0053] In an optional embodiment of this invention, the buffer assembly 1 further includes at least two damping buffer members 5 installed between the buffer box frame 11 and the mounting plate 2, with at least some of the damping buffer members 5 arranged on opposite sides of the elastic steel 52. For example, as Figures 1 to 3 As shown, at least one damping buffer 5 is arranged on both the left and right sides of the elastic steel 52. The specific structure of the damping buffer 5 may include, but is not limited to, a guide post extending in the front-back direction and a spring sleeved on the outside of the guide post, as shown in the figure; or, it may only include a guide post extending in the front-back direction made of elastic material such as nylon; or, it may only include a damping structure such as a spring arranged in the front-back direction. The specific number of damping buffers 5 is not specifically limited. For example, but not limited to, three damping buffers 5 are arranged as a group, with one group of damping buffers 5 arranged on each of the left and right sides of the elastic steel 52.

[0054] In this optional embodiment, the damping buffer 5, as an important component of the buffer system, can effectively assist the elastic steel 52 in performing efficient buffering and energy absorption. When a vehicle collides violently with this device due to an accident, the damping buffer 5 will work in conjunction with the elastic steel 52. Based on its unique structural design and material properties, such as the internal damping medium and special mechanical structure, the damping buffer 5 responds rapidly at the moment of impact. It and the elastic steel 52 deform simultaneously. The elastic steel 52 mainly relies on its elastic deformation to initially absorb and disperse the impact energy, while the damping buffer 5 focuses on... By converting kinetic energy into heat and other forms of energy through internal damping, the impact force is reduced in a multi-dimensional and profound way. The two complement each other and work closely together to buffer and absorb energy during a violent vehicle collision. This not only effectively reduces the damage to the vehicle and the device itself, but also complements each other in different energy conversion and buffering mechanisms. This improves the practicality and reliability of the flexible collision avoidance traffic safety facility in dealing with various complex collision scenarios, enabling it to better adapt to the ever-changing road traffic safety needs and provide a more solid guarantee for protecting vehicles, pedestrians and road infrastructure.

[0055] To ensure that other buffer structures in the buffer assembly 1, besides the buffer pad 12, located between the buffer box frame 11 and the mounting plate 2, can be successfully triggered, in an optional embodiment of this example, the buffer assembly 1 further includes a plurality of connecting posts 51 installed between the buffer box frame 11 and the mounting plate 2. At least some of the connecting posts 51 are arranged on opposite sides of the elastic steel 52. One end of each connecting post 51 is fixedly installed on the buffer box frame 11, and the other end is suspended or abuts against the mounting plate 2; or, one end of each connecting post 51 is fixedly installed on the mounting plate 2, and the other end is suspended or abuts against the buffer box frame 11; or, one end of each connecting post 51 is fixedly installed on the buffer box frame 11, and the other end is fixedly installed on the mounting plate 2. For example, as... Figures 1 to 3 As shown, at least one set of connecting columns 51 are arranged on the upper and lower sides of the elastic steel 52, and multiple connecting columns 51 are arranged at intervals in each set along the left and right direction. The spacing between any two adjacent connecting columns 51 is equal or unequal (preferably equal for uniform distribution). The connecting columns 51 can be inclined or extend along the front and back direction to provide a buffer space between the buffer box frame 11 and the mounting plate 2.

[0056] In this optional embodiment, the connecting column 51, as an important component connecting the buffer box frame 11 and the mounting plate 2, not only undertakes a simple connecting function, but is also a key component that enables the other buffer components of the flexible anti-collision traffic safety facility, except for the buffer pad 12, to be triggered. Its material has good toughness and strength, and its structural design fully considers mechanical principles and buffering requirements. When a vehicle collides with the device, the connecting column 51 can quickly sense the huge impact force due to its own characteristics, and based on this impact force, it will produce a misaligned bending phenomenon. This misaligned bending is not random damage, but a deformation that follows a pre-designed path and method. It cleverly converts the linear impact force transmitted by the vehicle into the bending potential energy of the connecting column 51 itself, as well as some thermal energy and other forms of energy, thereby effectively dispersing the impact force and ensuring that the buffer space between the buffer box frame 11 and the mounting plate 2 can be fully utilized. This allows other buffer structures located between the buffer box frame 11 and the mounting plate 2 to be successfully triggered, thereby minimizing the damage to the vehicle and the device, ensuring road traffic safety, and improving the reliability and durability of the device itself.

[0057] The structures provided by the above-mentioned optional embodiments of this example can be combined. When the buffer box frame 11, buffer pad 12, elastic steel 52, damping buffer 5, and connecting column 51 are designed simultaneously, when a vehicle unfortunately collides with this flexible anti-collision traffic safety facility, the buffer pad 12 is the first to come into contact. Under the action of its unique honeycomb hole 121 structure, the buffer pad 12 can effectively reduce the impact force. When the vehicle collision force is large and exceeds the buffer range that the buffer pad 12 can withstand alone, the elastic steel 52, damping buffer 5, and connecting column 51 are activated and work together. The connecting column 51 is displaced and bent to absorb energy, the elastic steel 52 deforms to absorb energy, and the damping buffer 5 assists in buffering and converting energy. Through the joint action of these multi-layered and multi-mechanism buffering energy-absorbing components, the remaining impact energy of the vehicle is further absorbed and converted, thereby comprehensively ensuring that the vehicle can minimize the degree of damage under high-intensity collisions and providing a solid and reliable protective guarantee for road traffic safety.

[0058] To facilitate the installation of this flexible anti-collision traffic safety facility, in an optional embodiment of this example, the support mounting frame 3 and the mounting plate 2 are connected in a detachable manner.

[0059] Specifically, such as Figure 5 As shown, in an optional embodiment of this example, a snap-fit ​​seat 21 is provided on the side surface of the mounting plate 2 facing the support mounting frame 3. The snap-fit ​​seat 21 is provided with a snap-fit ​​groove 22, and a snap-fit ​​block 31 is provided on the side surface of the support mounting frame 3 facing the snap-fit ​​seat 21. The support mounting frame 3 is snapped together with the snap-fit ​​block 31 and the snap-fit ​​groove 22. A mounting part 32 is provided at the bottom of the support mounting frame 3. The mounting part 32 may be, but is not limited to, a mounting hole penetrating one end of the support mounting frame 3 or a flange or other specific type of mounting base fixedly connected to the support mounting frame 3.

[0060] Taking the installation part as an example, when installing this flexible anti-collision traffic safety facility, firstly, select a suitable installation point for drilling according to the actual situation of the installation site (when there are two or more installation holes, the distance between adjacent installation holes should be further measured to accurately determine the installation point before drilling); after drilling, place the support mounting bracket 3 on the installation hole, aligning the installation hole with the drilled hole, and then connect and fix the support mounting bracket 3 to the ground with bolts; after fixing, place the mounting plate 2 on top of the support mounting bracket 3, aligning the snap-fit ​​groove 22 with the snap-fit ​​block 31, and then move the mounting plate 2 downward so that the mounting plate 2 and the support mounting bracket 3 snap together.

[0061] In this optional embodiment, the ingenious interlocking design between the snap-fit ​​block 31 and the snap-fit ​​slot 22 achieves a convenient working mode for quick disassembly and installation. When the equipment needs to be installed, the operator only needs to align the snap-fit ​​block 31 with the snap-fit ​​slot 22 and push it in; the two will then precisely engage and quickly complete the connection, building a stable structure. When disassembly is required for maintenance, replacement, or equipment relocation, only appropriate external force needs to be applied to detach the snap-fit ​​block 31 from the snap-fit ​​slot 22, easily achieving separation. This greatly saves time and labor costs, and improves the flexibility and convenience of equipment use. The mounting section ensures that the mounting bracket is accurately positioned on the ground.

[0062] In an optional embodiment of this example, the snap-fit ​​groove 22 is strip-shaped and has two sections, which are symmetrical about the center of the snap-fit ​​base 21. The support mounting bracket 3 is provided with two strip-shaped snap-fit ​​blocks 31 that correspond one-to-one with the two snap-fit ​​grooves 22. In this optional embodiment, during installation, the mounting bracket plate 2 needs to be lifted from both sides simultaneously to complete the snap-fit ​​operation. This structural design ensures that even if one side of the mounting bracket plate 2 is lifted later, the mounting bracket plate 2 will not separate from the support mounting bracket 3 because the other side of the mounting bracket plate 2 is squeezed and locked, thereby further improving the installation stability after snap-fit.

[0063] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to mutually. The above embodiments in this specification are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model.
