Detailed implementation manners
[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0045] Please refer to Figures 1 to 13 Figures 1 to 13 , this embodiment provides a steerable anti-collision cushion, which includes an anchoring column 1 fixed to the ground. Two parallel guide rails 2 are detachably connected to the anchoring column 1. The guide rails 2 are fixed to the anchoring column 1 using hoop clamps and can be disassembled and reinstalled at an adjusted height according to requirements. One end of the guide rail 2 is fixed to the ground using flange bolts, and a plurality of first support frames 3 that can slide along its length are connected to the guide rail 2. A first energy absorption plate 4 is provided between any two of the first support frames 3. On both sides of the plurality of first support frames 3, there are multiple second energy absorption plates 5 connected to each other.
[0046] In this embodiment, the plurality of first support frames 3 are supported by the ground and can slide along the guide rail 2. Specifically, when the anti-collision cushion is impacted by a collision object such as a car, it can be guided along the direction of the guide rail 2 to reduce the risk of deviation and rollover. The first energy absorption plate 4, the second energy absorption plates 5, and the first support frames 3 together form a structurally compact energy absorption structure, which can effectively absorb collision energy and reduce the damage of the impact force to the collision object and the surrounding environment. It should be particularly noted that the difference between this embodiment and the anti-collision cushions in the prior art is that the main energy absorption structure is an energy absorption plate with excellent energy absorption effect. Therefore, there is no need to set other components inside the anti-collision cushion, which can not only take into account the anti-collision performance but also lightweight the design of the anti-collision cushion, greatly reducing the production cost.
[0047] Further, as a preferred implementation manner rather than a limitation of this solution, the second energy absorption plate 5 is in a waveform. A plurality of energy absorption holes 51 for buffering during a collision are uniformly arranged along the plate length direction between any two wave crests of the second energy absorption plate 5. One side of the second energy absorption plate 5 is also provided with a first mounting hole 52 corresponding to the energy absorption hole 51 on the adjacent second energy absorption plate 5. The first mounting hole 52 and the energy absorption hole 51 on the adjacent second energy absorption plate 5 are connected to the first support frame 3 through fasteners.
[0048] In this embodiment, the second energy absorption plate 5 is in a waveform, which can increase the energy absorption area and improve its energy absorption effect. At the same time, the waveform structure can also increase the structural stability and reduce deformation. A plurality of energy absorption holes 51 are uniformly arranged along the plate length direction between any two wave crests of the second energy absorption plate 5. Specifically, the best positions for these energy absorption holes 51 are at the wave valleys between two wave crests and are linearly arranged along the length direction of the energy absorption plate. Of course, in some other embodiments, they can also be arranged on the inclined surfaces between the wave crests and wave valleys of the second energy absorption plate 5. The first mounting hole 52 on the second energy absorption plate 5 and the energy absorption hole 51 on the adjacent second energy absorption plate 5 are connected to the first support frame 3 through fasteners, which is convenient for installation and disassembly to meet different installation requirements.
[0049] In a real collision scenario, when a colliding object such as a vehicle collides with the steerable anti-collision pad proposed in this embodiment, the second energy absorption plate 5 deforms along the direction of the guide rail 2. The energy absorption holes 51 on the second energy absorption plate 5 will be pressed against the fasteners and subjected to shear force, causing them to deform, thereby achieving the effect of energy absorption and buffering until the energy absorption holes 51 are torn. Another energy absorption hole 51 adjacent to the energy absorption hole 51 will continue to be stressed and deformed to absorb energy, reducing the adverse effects of the impact on the vehicle and personnel.
[0050] Further, as Figure 4 、 Figure 6 、 Figure 7 shown, the energy absorption hole 51 is a polygonal hole with each inner side tangent to the fastener. The tangency design of the polygonal energy absorption hole 51 and the fastener can enhance the connection stability between the fastener and the second energy absorption plate 5, reducing the risk of loosening or falling off during the impact. On the other hand, when the polygonal energy absorption hole 51 is subjected to an impact, its shape helps to concentrate the impact force, and it is more likely to generate stress concentration and thus undergo energy absorption deformation compared to ordinary round holes, improving the energy absorption efficiency.
[0051] Specifically, as Figure 4 shown, the energy absorption hole 51 is preferably an equilateral triangular hole, and one of the edges of the equilateral triangular hole is oriented in the same direction as the length direction of the second energy absorption plate 5. When a collision occurs, the edge of the equilateral triangular hole can be pressed against the fastener and absorb energy under shear. Triangles have the characteristic of strong stability, but when encountering a collision, the edges of the triangular hole are more likely to generate stress concentration and thus be squeezed and deformed compared to other shapes. Utilizing this characteristic, the energy absorption hole 51 can have a good energy absorption and buffering effect. In some other embodiments, the energy absorption hole 51 can also be in the shape of a rhombus, rectangle, regular hexagon, etc.
[0052] Further, as Figure 5 shown, the energy absorption hole 51 is a curved hole with a continuous smooth curve and inner sides tangent to the fastener. In some other embodiments, the energy absorption hole 51 can also be in the shape of a round hole, oblong hole, oval hole, etc. with a continuous smooth curve. Different from the regular polygonal energy absorption hole, the anti-collision pad with a curved energy absorption hole has a higher stiffness and thus better durability. However, because the stress distribution it receives during impact is relatively more uniform, its energy absorption and buffering effect is slightly worse than that of the anti-collision pad with a regular polygonal energy absorption hole.
[0053] Further, as a preferred implementation manner rather than a limitation of the present solution, a gasket 6 for preventing fasteners from detaching when the energy absorption holes 51 are deformed during a collision is also provided between any two wave crests of the second energy absorption plate 5. The fastener sequentially passes through the gasket 6, the energy absorption hole 51, and the first mounting hole 52 on the adjacent second energy absorption plate 5 from outside to inside and then is fixed to the first support frame 3. The cross-sectional shape of the gasket 6 matches the waveform of the second energy absorption plate 5.
[0054] In this embodiment, the gasket 6 is used to press the second energy absorption plate 5 and at the same time prevent the bolts from coming out due to the increase in the aperture of the energy absorption hole 51 when the anti-collision pad is deformed by absorbing energy during a collision, which is of great significance for maintaining the buffering and energy absorption effect of the energy absorption hole 51.
[0055] Further, as a preferred implementation manner rather than a limitation of the present solution, a raised surface 53 is provided at one end of the second energy absorption plate 5 that is far from the first mounting hole 52 and close to the gasket 6 to avoid direct physical contact with the gasket 6 on the adjacent second energy absorption plate 5 during collision deformation, which may cause uneven energy absorption.
[0056] Specifically, when the impact-resistant anti-collision pad proposed in this embodiment is impacted, the second energy absorption plate 5 will be deformed and displaced backward under extrusion. At this time, the edge of the deformed second energy absorption plate 5 may press against the gasket 6 provided on the adjacent second energy absorption plate 5, resulting in uneven energy absorption. By providing the raised surface 53, this situation can be effectively avoided.
[0057] Further, the distance between adjacent energy absorption holes 51 is 5 - 15 mm, preferably 10 mm. This distance setting is based on a comprehensive consideration of the energy absorption efficiency and structural stability of the anti-collision pad. The anti-collision pad can achieve a more uniform energy absorption and buffering effect during the impact process, improving the overall energy absorption efficiency. On the other hand, it provides convenience for the installation and maintenance of the fasteners and ensures the smooth progress of the installation process.
[0058] Further, as a preferred implementation manner rather than a limitation of the present solution, the first energy absorption plate 4 includes an arc-shaped plate 41. For details, please refer to Figure 8 The surface of the arc-shaped plate 41 is provided with a plurality of rib surfaces 42 formed by stamping for improving the energy absorption effect. Installation edges 43 connected to the first support frame 3 are respectively provided on both sides of the arc-shaped plate 41, and second mounting holes 44 for fixing the fasteners to the first support frame 3 are provided on the installation edges 43.
[0059] In this embodiment, the first energy absorption plate 4 is mainly composed of an arc-shaped plate 41. This arc-shaped design helps to provide a better energy absorption and dispersion path when being impacted. The ribbed surface 42 formed by stamping on the surface of the arc-shaped plate 41 increases the local stiffness of the plate and at the same time has a certain shrinkage performance, and can achieve the energy absorption and buffering effect through local deformation when being impacted.
[0060] Furthermore, as a preferred implementation manner rather than a limitation of this solution, the first energy absorption plate 4 further includes a corrugated plate 45. Please refer to Figures 9 - 10 , the peaks and valleys of the corrugated plate 45 are parallel to the first support frame 3. Installation edges 43 connected to the first support frame 3 are respectively provided on both sides of the corrugated plate 45, and second installation holes 44 for fixing the fasteners to the first support frame 3 are provided on the installation edges 43.
[0061] Different from the first energy absorption plate 4 with the above-mentioned arc-shaped design, in this embodiment, by setting the corrugated plate 45 with peaks and valleys parallel to the first support frame 3, the corrugated plate 45 can cooperate with the first support frame 3 to improve the overall energy absorption efficiency. Specifically, when the anti-collision pad is impacted, the corrugated plate 45 generates a compression displacement under the action of an external force, thereby achieving the effect of buffering and energy absorption.
[0062] Furthermore, as a preferred implementation manner rather than a limitation of this solution, a second support frame 7 that can slide along its length direction and maintains the overall stability during the collision process is further connected to one end of the guide rail 2 close to the ground. The first energy absorption plate 4 is connected between the second support frame 7 and the first support frame 3. The first support frame 3 includes a frame body 31. Support columns 32 matching the number of the guide rails 2 are provided at the lower part of the frame body 31. A first connecting beam 33 is provided between the lower parts of the support columns 32. A sleeve 34 sleeved on the guide rail 2 is provided on the side of the support column 32. Third installation holes 35 corresponding to the first installation holes 52 for installing the second energy absorption plate 5 are provided on both sides of the frame body 31, and fourth installation holes 36 corresponding to the second installation holes 44 for installing the first energy absorption plate 4 are provided at the upper part of the frame body 31; the second support frame 7 includes at least two of the first support frames 3, and a plurality of second connecting beams 71 are evenly provided between two adjacent first support frames 3.
[0063] In this embodiment, through the cooperation of the support columns 32 and the sleeves 34, the first support frame 3 and the second support frame 7 can be stably connected to the guide rail 2, improving the stability of the overall structure of the anti-collision pad. At the same time, when being impacted, it can be guided along the length direction of the guide rail 2, reducing the risk of the collided object such as a vehicle rolling over or deviating.
[0064] It should be particularly noted that since the second support frame 7 is provided with at least four support columns 32, at least four support points are provided to maintain the overall frame movement stability of the anti-collision pad during the collision process, and prevent the poor energy absorption and buffering effect caused by the uneven force on the first energy absorption plate 4 and the second energy absorption plate 5.
[0065] Furthermore, as a preferred implementation manner of this solution rather than a limitation, a front protection plate 8 is provided on the side end of the second support frame 7. Flanking plates 81 that cover the ends of the second energy absorption plate 5 are bent and extended from both side ends of the front protection plate 8. A plurality of mounting portions 83 for fixedly connecting with the second energy absorption plate 5 are provided on the flanking plates 81. When a collision occurs, the front protection plate 8 prevents the second energy absorption plate 5 from directly physically contacting the collision object; a reflective marking 82 for improving visibility at night and under bad weather conditions is also provided on the surface of the front protection plate 8, which helps to improve the visibility of the anti-collision pad and reduce the collision risk at night or in low visibility conditions.
[0066] In this embodiment, a front protection plate 8 is provided on the side end of the second support frame 7. This protection plate provides an additional protection layer for the anti-collision pad to resist direct impact. At the same time, flanking plates 81 are bent and extended from both side ends of the front protection plate 8, and these flanking plates cover the ends of the second energy absorption plate 5 to avoid direct physical contact with the collision object. For example, in an actual scenario, it can effectively prevent the second energy absorption plate 5 from penetrating the vehicle when the vehicle collides with the anti-collision pad.
[0067] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the guide rail 2 gradually rises from the end fixed to the ground to the end connected to the anchor post 1, presenting a gradually changing structure with a lower front and a higher rear.
[0068] In this embodiment, the design of the guide rail 2 with a lower front and a higher rear helps to direct the energy upward and rearward during the impact, reducing the impact on the bottom and fixing points of the anti-collision pad. At the same time, it helps to maintain the overall stability of the anti-collision pad during the impact process and reduce the structural deformation caused by the impact. In an actual scenario, when a vehicle collides, the impact force can be dispersed along the gradually rising direction of the guide rail, thereby prolonging the impact process time. This helps to reduce the impact force received per unit time and improve the energy absorption efficiency. On the other hand, it can guide the vehicle to move in a more optimal direction during the collision process, reducing the direct and violent impact backward or to the side and reducing the potential harm to passengers and the vehicle. Further, setting the front end at a lower height ensures that the vehicle impact surface is at the same height as the anti-collision pad's impact surface, thereby achieving a better energy absorption effect, and the higher end at the rear also facilitates a smooth transition and connection with the standard steel guardrail at the rear.
[0069] The working principle of the present utility model:
[0070] This application proposes a steerable anti-collision pad, which is fixed to the ground by an anchor column. Two parallel guide rails are detachably connected to the column, and the guide rails and the column are fixed using hoop clamps. The installation height can be adjusted according to requirements. One end of the guide rail is fixed to the ground using flange bolts to ensure stability.
[0071] A plurality of first support frames that can slide along the length direction of the guide rail are connected to the guide rail. These frames support the ground and can be guided along the direction of the guide rail when the anti-collision pad is collided, reducing the risk of deviation and rollover.
[0072] A first energy absorption plate is provided between any two first support frames, and a plurality of second energy absorption plates connected to each other are respectively provided on both sides of the plurality of first support frames. These energy absorption plates together constitute a compact energy absorption structure, which can effectively absorb collision energy and reduce the damage of the impact force to the collided object and the surrounding environment.
[0073] The second energy absorption plate is in a waveform, increasing the energy absorption area and the stability of the structure. A plurality of energy absorption holes are provided between the wave crests for buffering during collision. The energy absorption holes are polygonal holes or curved holes, and are designed to be tangent to the fasteners, enhancing the connection stability and improving the energy absorption efficiency.
[0074] A gasket is also provided between the wave crests of the second energy absorption plate to prevent the fasteners from detaching when the energy absorption holes are deformed during collision. In addition, a convex surface is provided on the second energy absorption plate to avoid direct contact with the gasket on the adjacent second energy absorption plate during collision deformation, resulting in uneven energy absorption.
[0075] The first energy absorption plate includes an arc plate or a waveform plate. When an arc plate is used, a plurality of rib surfaces formed by stamping are provided on the surface to improve the energy absorption effect. Installation edges are provided on both sides for connecting to the first support frame.
[0076] A second support frame that can slide along the length direction of the guide rail is connected to one end of the guide rail close to the ground to maintain the overall stability during the collision process. A first energy absorption plate is connected between the second support frame and the first support frame.
[0077] A front protection plate is provided on the side end cover of the second support frame to prevent the second energy absorption plate from directly contacting the collided object. A reflective marking is also provided on the surface of the protection plate to improve visibility at night and in bad weather conditions.
[0078] The guide rail gradually rises from the end fixed to the ground to the end connected to the anchor column, showing a gradually changing structure with the front end lower and the rear end higher, which helps to direct the energy upward and backward during impact, reducing the impact on the bottom and fixed points of the anti-collision pad.
[0079] Through these designs, the steerable anti-collision pad can effectively absorb energy when collided, reduce the damage to the collided object and the surrounding environment, and at the same time maintain its own stability and durability.
[0080] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of this application is only limited to these descriptions. Any structure similar to the method of this application, or several technical deductions or substitutions made on the premise of the concept of this application, shall be regarded as the protection scope of this application.
