Description

Technical Field

[0001] This utility model relates to the field of anti-collision buffer vehicles, and in particular to an anti-side impact buffer pack for anti-collision buffer vehicles. Background Technology

[0002] Collision buffer vehicles are one of the important tools used in road protection to reduce the impact on personnel safety during road construction. When constructing roads, a vehicle equipped with a collision buffer energy absorption device at the rear needs to be placed behind the construction work area. In the event of a rear-end collision, a buffer zone can be created between the offending vehicle and the construction work area in front. The energy of the impact can be absorbed by the deformation of the equipment structure, minimizing the probability of collision to the protected personnel and equipment.

[0003] Currently, collision buffer energy absorption devices are allowed to deform significantly during vehicle collisions in order to absorb impact energy reasonably. However, if they encounter impact forces exceeding the allowable range, especially when subjected to offset angle collisions, the buffer device may break at the middle connection point, making it difficult to guarantee the personal safety of workers in the construction area in front of the vehicle.

[0004] Therefore, it is necessary to improve the anti-collision devices of current road construction vehicles. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3 As shown, the embodiments of this utility model include:

[0021] A collision avoidance buffer pack for a vehicle includes a shell 1, honeycomb energy-absorbing horizontal plates 2, a top cover 3, a base 4, and a front cover 5 riveted together. The shell 1 is a single plate structure and is bent to form a square groove shape. Several honeycomb energy-absorbing horizontal plates 2 are stacked inside the shell 1. The two ends of the shell 1 are respectively encapsulated with the front cover 5 and the base 4, which wrap around the honeycomb energy-absorbing horizontal plates 2. The top cover 3 covers all the honeycomb energy-absorbing horizontal plates 2 and is connected to the top edge of the shell 1. The two ends of the top cover 3 are respectively connected to the base 4 and the front cover 5. A buffer plate 6 is provided on the outer side of the front cover 5.

[0022] The honeycomb energy-absorbing horizontal plate 2 and the outer shell 1 are provided with a lateral gap, and a plurality of honeycomb energy-absorbing vertical plates 7 are stacked and filled in the lateral gap. The honeycomb energy-absorbing vertical plates 7 are perpendicular to the honeycomb energy-absorbing horizontal plate 2.

[0023] Furthermore, the honeycomb energy-absorbing horizontal plate 2 is divided into a front half 8 and a rear half 9, and a middle partition 10 is stacked between the front half 8 and the rear half 9.

[0024] Furthermore, the outer edge of the front half 8 is vertically stacked with a left offset collision honeycomb plate 11, a central collision honeycomb plate 12, and a right offset collision honeycomb plate 13, and the front cover plate 5 covers the left offset collision honeycomb plate 11, the central collision honeycomb plate 12, and the right offset collision honeycomb plate 13.

[0025] Furthermore, the corners of the left offset collision honeycomb plate 11 and the right offset collision honeycomb plate 13 are provided with reinforcing bending plates 14, which are angle steel.

[0026] Furthermore, the outer wall of the honeycomb energy-absorbing longitudinal plate 7 is provided with a plurality of bent riveting plates 15 at equal intervals. The bent riveting plates 15 are C-shaped and fasten the honeycomb energy-absorbing longitudinal plate 7 to the honeycomb energy-absorbing transverse plate 2.

[0027] The C-shaped bend plate is designed to better and more securely connect the outer shell and the cover plate.

[0028] Furthermore, the base 4 is composed of a bottom bending plate 16, a bottom surrounding plate 17, and a bottom plate 18. The bottom bending plate 16, the bottom surrounding plate 17, and the bottom plate 18 are riveted together to form a box structure, which encloses the honeycomb energy-absorbing horizontal plate 2.

[0029] Furthermore, the inner bottom surface of the base 4 is provided with a plurality of equally spaced fixing strips 19, which are connected to the honeycomb energy-absorbing horizontal plate 2.

[0030] Specifically, the outer shell 1 and the upper cover plate 3 are made of a single plate to increase the overall robustness of the product's anti-collision buffer pack; wherein, the outer shell 1, the upper cover plate 3, the middle partition plate 10, the front cover plate 5, and the bent riveted plate 15 are made of rust-proof and corrosion-resistant aluminum alloy material, such as: 3003 aluminum alloy, 3004 aluminum alloy, 5052 aluminum alloy, 5083 aluminum alloy, etc.

[0031] In addition, the honeycomb energy-absorbing horizontal plate 2 and the honeycomb energy-absorbing vertical plate 7 are made of energy-absorbing material with an internal structure of aluminum honeycomb, and are made of a whole plate to prevent the honeycomb energy-absorbing material from being squeezed and disintegrating when the product's anti-collision bag is subjected to impact force; the honeycomb energy-absorbing material can be aluminum alloy honeycomb plate, aluminum alloy + aramid honeycomb core plate, aluminum alloy corrugated core plate, etc.

[0032] The impact-absorbing pad of this product has a buffer plate 6 installed at its front end made of polymer material, which can better absorb impact energy as a buffer layer; the polymer material used for this buffer layer can be EVA, TPE, POE, aliphatic TPU, PUR, EPE, etc.

[0033] Furthermore, the base 4 of this product will be made of high-strength structural steel, such as Q355 series steel, Q345 series steel, 40Cr / 42CrMo alloy structural steel, etc. The base 4 is mainly used to fix the outer shell 1 and the upper cover plate 3, and at the same time connects to the vehicle body seat of the anti-collision buffer vehicle.

[0034] This product is assembled into a complete box by riveting the base 4, outer shell 1, upper cover plate 3, middle partition plate 10, front cover plate 5, and bending and riveting plate 15 together. The inside is filled with honeycomb energy-absorbing material, which consists of honeycomb energy-absorbing horizontal plates 2 and vertical plates. A buffer plate 6 is installed at the front end. Multi-level energy absorption is achieved through the buffer plate 6, the front half 8, and the rear half 9.

[0035] Since the outer shell 1 and the upper cover plate 3 are made of a single piece of material and are reinforced laterally by bending and riveting plate 15, there is no risk of breakage or disintegration when encountering impact forces exceeding the range or impacts at an offset angle. The energy-absorbing part of the internal honeycomb energy-absorbing material is also made of a single piece of material and stacked together, resulting in strong overall structural consistency. When encountering impact forces exceeding the range or impacts at an offset angle, it can effectively transmit the stress caused by compression of the outer shell 1 and the cover plate, resulting in excellent stability.

[0036] Through the above methods, this product can effectively solve the problem of the collision avoidance device of road construction vehicles breaking at the middle connection when it encounters an impact force that exceeds the range or an off-angle impact.

[0037] In summary, this utility model provides a collision buffer pack for a vehicle designed to prevent off-center collisions. The reinforced box structure with excellent consistency is achieved by riveting the base 4, outer shell 1, upper cover plate 3, middle partition plate 10, front cover plate 5, and bent riveting plate 15 together. This provides a reliable energy transfer interface for overload energy caused by off-center collisions, allowing the honeycomb panel to fully buffer and absorb energy, effectively suppressing local stress disintegration problems, and significantly improving collision safety.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
