Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision buffer vehicle accessories, specifically to an anti-collision pad for an anti-collision buffer vehicle. Background Technology

[0002] Crash buffer vehicles are commonly used safety equipment in road construction, accident handling, and other scenarios. The performance of their core component, the crash pad, directly affects the energy absorption effect and the safety of personnel and equipment during a collision. Most existing crash buffer vehicle crash pads use only a single energy-absorbing structure for energy buffering, resulting in low energy absorption efficiency and insufficient buffer stroke. When subjected to large impact forces, they are unable to fully absorb collision energy, easily leading to damage to the crash pad structure and even causing secondary injuries to the colliding vehicle and personnel.

[0003] Therefore, there is an urgent need for a collision buffer pad for vehicles that has excellent energy absorption, stable and reliable cushioning, and a long service life to solve the above problems. Utility Model Content

[0004] This utility model aims to solve the above-mentioned technical problems by providing a crash pad for a crash-proof buffer vehicle.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A crash cushion for a crash protection vehicle includes a cushioning element and a cushioning box filled with energy-absorbing filler. The buffer box is equipped with a partition that divides the buffer box into a buffer zone and an energy absorption zone. Energy-absorbing components are installed within the energy-absorbing zone; The buffer box has an outer side that can push the energy-absorbing component to the buffer energy-absorbing steel plate, and multiple sets of buffer rods are installed between the buffer component and the steel plate.

[0006] Preferably, a cushioning rubber is installed in the buffer zone.

[0007] Preferably, the energy-absorbing component includes a rubber frame installed in the energy-absorbing zone, a plurality of honeycomb columns are installed in the rubber frame, and rubber ring columns are installed in the honeycomb columns.

[0008] Preferably, the steel plate has sliding holes that move on the outside and inside of the buffer box.

[0009] Preferably, the buffer box has sliding grooves on both sides to facilitate its movement.

[0010] Preferably, multiple sets of springs are installed between the steel plate and the buffer box.

[0011] Preferably, a baffle for blocking the spring is installed on the outer side of the steel plate.

[0012] With the above structure, this utility model has the following advantages: This invention achieves the first layer of energy absorption through the energy-absorbing filler inside the buffer component, the second layer of buffering through the buffer rubber inside the buffer box, and the third layer of efficient energy absorption through the synergy of the honeycomb columns and rubber ring columns in the energy-absorbing zone. At the same time, the buffer rod and spring provide auxiliary buffering. The combination of multiple structures can fully absorb collision energy, significantly improve the buffering effect, and effectively reduce the damage to vehicles and people caused by collisions.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0023] The present invention will now be described in further detail in conjunction with the full text.

[0024] Combined with appendix Figures 1-5 A crash cushion for a crash-resistant vehicle includes a buffer component 1 filled with energy-absorbing filler and a buffer box 2. The buffer box 2 has an internal partition 3 that divides it into an independent buffer zone 201 and an energy-absorbing zone 202. An energy-absorbing component 4 is fixedly installed in the energy-absorbing zone 202. A steel plate 5, movable axially along the buffer box 2, is located on the outside of the buffer box 2. The steel plate 5 can compress and push the energy-absorbing component 4 during movement. Multiple sets of evenly distributed buffer rods 6 are fixedly installed between the buffer component 1 and the steel plate 5. The energy-absorbing filler can be made of materials with good energy absorption properties, such as polyurethane foam or rubber granules. The partition 3 is welded and fixed inside the buffer box 2, dividing the internal space into the buffer zone 201 and the energy-absorbing zone 202. A buffer rubber 7, made of highly elastic natural rubber, is fixedly installed in the buffer zone 201 by bolts, providing initial cushioning.

[0025] Specifically, a buffer rubber 7 is fixedly installed inside the buffer zone 201. The buffer rubber 7 is tightly fitted with the partition 3, which can initially buffer the impact force. Multiple honeycomb columns 402 are integrally formed inside the rubber frame 401 in a matrix distribution. The honeycomb columns 402 are made of aluminum alloy and have good crush energy absorption performance. A rubber ring column 403 is nested and fixed inside each honeycomb column 402. The rubber ring column 403 is tightly fitted with the honeycomb column 402, which can further improve the energy absorption effect.

[0026] The energy-absorbing component 4 includes a rubber frame 401 fixedly installed in the energy-absorbing zone 202. Multiple sets of honeycomb columns 402 arranged in an array are fixedly installed in the rubber frame 401. Rubber ring columns 403 are fixedly nested in the honeycomb columns 402. The honeycomb columns 402 and the rubber ring columns 403 work together to achieve efficient energy absorption.

[0027] In practical use, this utility model, such as Figure 2 and Figure 4As shown, the steel plate 5 has sliding holes 8, and the side walls of the buffer box 2 have sliding grooves 9. The steel plate 5 can move outside and inside the buffer box 2 through the sliding holes 8, allowing the steel plate 5 to move stably within the energy absorption zone 202. Multiple sets of springs 10 are welded and fixed between the steel plate 5 and the buffer box 2. The springs 10 are high-strength alloy springs, symmetrically distributed on both sides of the buffer box 2. Baffles 11, made of stainless steel, are bolted to the outer side of the steel plate 5. Two sets of baffles 11 are located on either side of the springs 10, providing protection for the springs 10.

[0028] In a specific implementation of this utility model, multiple sets of symmetrically distributed springs 10 are fixedly installed between the steel plate 5 and the buffer box 2. The springs 10 can provide auxiliary buffering force and achieve reset when the steel plate 5 moves. A baffle 11 is fixedly installed on the outer side of the steel plate 5. The two sets of baffles 11 are located on both sides of the springs 10 respectively, and are used to shield and protect the springs 10. The buffer box 2 and the baffles 11 are staggered.

[0029] The working principle of this utility model: Upon collision, the impact force first acts on buffer 1, causing the energy-absorbing filler within buffer 1 to deform and absorb some of the energy. Subsequently, buffer 1 pushes buffer rod 6, which in turn moves steel plate 5 along the guide direction of sliding hole 8 and sliding groove 9 towards buffer box 2. During this movement, steel plate 5 compresses spring 10, causing it to elastically deform and absorb energy. When steel plate 5 contacts energy-absorbing component 4, it causes the honeycomb pillars 402 within energy-absorbing component 4 to crush and deform, while simultaneously the rubber ring pillars 403 undergo elastic deformation, further absorbing collision energy. During this process, the buffer rubber 7 within buffer zone 201 can also assist in absorbing energy through deformation. The synergistic effect of these multiple energy-absorbing structures achieves highly efficient buffering. After the collision, the elastic restoring force of spring 10 can reset steel plate 5 and buffer rod 6, facilitating future use.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
