Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle technical field, concretely relates to a vehicle lightning protection assembly. BACKGROUND

[0002] The lightning protection vehicle is mainly used for performing tasks in high-risk areas, such as anti-terrorism, peacekeeping, humanitarian rescue and the like. Since these vehicles often face the threat of landmines, IEDs (improvised explosive devices) and other explosives, the chassis design must have very high anti-explosion capability to protect the safety of the passengers in the vehicle. The existing lightning protection vehicle chassis has integrated various protection measures in the design to resist the initial explosion impact, such as landmines or improvised explosive devices, but when facing explosive threats, these vehicles often show insufficient "staged anti-explosion capability". This means that they may not be able to effectively maximize the reduction of the damage of the explosion.

[0003] CN111735346A discloses a vehicle bulletproof and lightning protection structure and a mine-resistant and ambush-resistant vehicle, the lower parts of the left side plate and the right side plate of the vehicle body are oppositely inclined inward and connected with the vehicle body bottom plate to form a U-shaped structure, and a U-shaped lightning protection plate is connected below the vehicle body bottom plate. Although the prior art discloses using a staged structure to weaken the impact performance layer by layer, since the bottom of the U-shaped lightning protection plate is a flat surface, it leads to excessive staging to reduce the rapid dispersion capability of the impact force of the explosive. When the explosive that the mine-resistant and ambush-resistant vehicle is facing is on one side below, the impact on the bottom of the U-shaped lightning protection plate needs to be first transferred by the inclined surface and then transferred through the flat surface to the other inclined surface, which increases the staging effect, but the design of the flat surface increases a transition space, so the impact force cannot quickly enter the large space of the other inclined surface for rapid dispersion, and therefore a vehicle lightning protection assembly that maintains the staged anti-explosion capability and improves the speed of dispersing the explosion impact is needed to be invented. SUMMARY

[0004] The utility model provides a vehicle lightning protection assembly, solve the problem that the prior art in the staging is excessive and leads to a reduction in the impact dispersion speed.

[0005] The technical solution of the utility model is as follows:

[0006] A vehicle lightning protection assembly, comprising at least two longitudinal beams, two longitudinal beams are provided with a two-stage lightning protection structure on one side, the two-stage lightning protection structure comprises a two-stage lightning protection plate arranged obliquely on the side of the longitudinal beam; the bottom of the two longitudinal beams is provided with a one-stage lightning protection structure, the one-stage lightning protection structure comprises a vertical plate fixed below the longitudinal beam and a one-stage lightning protection plate connected obliquely below the vertical plate, and the two one-stage lightning protection plates are symmetrically arranged and connected at the bottom of the inclined edge; the outside of the two-stage lightning protection plate, the vertical plate and the one-stage lightning protection plate is uniformly distributed with waveguide particles.

[0007] Further, the second-order lightning protection structure further comprises a plurality of triangular plates fixed to the side edges of the longitudinal beams, and the second-order lightning protection plates are fixed to the inclined edges of the triangular plates.

[0008] Further, the first-order lightning protection plate further comprises a sealing plate fixed between the two second-order lightning protection plates and the two vertical plates, and the sealing plate is obliquely arranged and fixed at the edges of the second-order lightning protection plates and the ends of the vertical plates.

[0009] Further, the outer part of the sealing plate is fixed with a connecting plate, and the connecting plate is L-shaped and fixed to the bottom of the longitudinal beam and the sealing plate on both sides.

[0010] Further, the waveguide particles are in strip shape.

[0011] The technical scheme provided by the application has the beneficial effects of:

[0012] 1. The vehicle lightning protection assembly cancels the flat design of the bottom of the traditional U-shaped lightning protection plate. This improvement not only reduces the staging of the impact force in the transmission process, but also significantly improves the dispersion speed of the impact force, so that the explosion impact can be more quickly spread in the chassis structure, thereby reducing the damage of concentrated impact to the vehicle and passengers.

[0013] 2. The vehicle lightning protection assembly, the waveguide particles uniformly distributed on the outside of the lightning protection assembly play an important role in the explosion resistance process. When the explosion shock wave acts on the vehicle chassis, the waveguide particles can further weaken the intensity of the shock wave through their rebound and expansion effect. At the same time, these particles can also guide the propagation direction of the shock wave, so that it is more evenly distributed on the entire chassis structure, avoiding excessive local impact force leading to structural damage. The synergistic effect of the waveguide particles and the inclined surface design enables the lightning protection assembly to more efficiently protect the safety of passengers in the vehicle and improve the survival ability of the vehicle when facing explosion threats.

DETAILED DESCRIPTION

[0019] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Reference Figs. 1-3 A vehicle lightning protection assembly includes at least two longitudinal beams 10, two longitudinal beams 10 are provided with two-stage lightning protection structures 20 on one side, two-stage lightning protection structures 20 include two-stage lightning protection plates 22 arranged obliquely on the side edges of longitudinal beams 10; The bottom of the two longitudinal beams 10 is provided with a one-stage lightning protection structure 30, the one-stage lightning protection structure 30 includes a vertical plate 31 fixed below the longitudinal beam 10 and a one-stage lightning protection plate 32 connected obliquely below the vertical plate 31, two adjacent one-stage lightning protection plates 32 are symmetrically arranged and the oblique edges of the bottom are connected to each other; The outside of the two-stage lightning protection plate 22, the vertical plate 31 and the one-stage lightning protection plate 32 are evenly distributed with waveguide particles 40. The one-stage lightning protection structure 30 is composed of the vertical plate 31 fixed below the longitudinal beam 10 and the one-stage lightning protection plate 32 arranged obliquely below, and two adjacent one-stage lightning protection plates 32 are symmetrically arranged and the oblique edges of the bottom are connected to each other; The two-stage lightning protection structure 20 includes two-stage lightning protection plates 22 arranged obliquely on the side edges of longitudinal beams 10. This design not only reduces the staging of impact force in the transmission process, but also significantly improves the dispersion speed of impact force, so that the explosion impact can be more quickly spread in the chassis structure, thereby reducing the damage of concentrated impact to the vehicle and the passengers. When the explosion shock wave acts on the vehicle chassis, the waveguide particles 40 first weaken the intensity of the shock wave through their rebound and expansion effect, and guide the propagation direction of the shock wave, so that it is more evenly distributed on the entire chassis structure. Subsequently, the oblique design of the one-stage lightning protection structure 30 and the two-stage lightning protection structure 20 enables the impact force to quickly spread in the chassis structure, reducing the staging of the impact force, thereby more effectively protecting the safety of the passengers in the vehicle and improving the survival ability of the vehicle.

[0021] In some embodiments, the second-order lightning protection structure 20 further comprises a plurality of triangular plates 21 fixed to the side edges of the longitudinal beam 10, and the second-order lightning protection plates 22 are fixed to the inclined edges of the triangular plates 21. The triangular plates 21 serve as connecting members to firmly fix the second-order lightning protection plates 22 to the longitudinal beam 10, thereby enhancing the overall stability of the second-order lightning protection structure 20. This design enables the second-order lightning protection plates 22 to more effectively transmit the impact force to the longitudinal beam 10 through the triangular plates 21 when subjected to side explosion impact force, thereby reducing the direct effect of the impact force on the side structure of the vehicle and better protecting the safety of the occupants in the vehicle. At the same time, the inclined edge design of the triangular plates 21 cooperates with the inclined arrangement of the second-order lightning protection plates 22 to enable the impact force to be transmitted and dispersed along an inclined path, further improving the blast resistance of the entire lightning protection assembly.

[0022] The first-order lightning protection plate 32 further comprises a sealing plate 33 fixed between the two second-order lightning protection plates 22 and the two vertical plates 31 from front to back, and the sealing plate 33 is arranged obliquely and fixed at the edges with the second-order lightning protection plates 22 and the vertical plates 31. This design makes the first-order lightning protection structure 30 more stable and can more effectively disperse the explosion impact force from the bottom of the vehicle, thereby reducing the concentration of impact force and better protecting the safety of the bottom structure of the vehicle and the occupants in the vehicle. The oblique arrangement of the sealing plate 33 cooperates with the second-order lightning protection plates 22 and the vertical plates 31 to further enhance the structural stability of the entire lightning protection assembly, enabling the impact force to be more evenly distributed on the entire chassis structure and avoiding excessive local impact force that can cause structural damage.

[0023] In some embodiments, the outer part of the sealing plate 33 is fixed with a connecting plate 34, which is L-shaped and fixed to the bottom of the longitudinal beam 10 and the sealing plate 33 on both sides. The connecting plate 34 tightly connects the sealing plate 33 and the longitudinal beam 10, enabling the impact force to be quickly transmitted to the longitudinal beam 10 through the connecting plate 34 and then dispersed to the entire chassis structure below. This design makes the connection between the sealing plate 33 and the longitudinal beam 10 more stable, thereby enhancing the structural stability of the entire lightning protection assembly. The L-shaped design of the connecting plate 34 enables the impact force to be more effectively transmitted and dispersed along the sealing plate 33 and the longitudinal beam 10, thereby reducing the concentration of impact force and better protecting the safety of the bottom structure of the vehicle and the occupants in the vehicle.

[0024] In some embodiments, the waveguide particles 40 are in the form of strips. If the shock wave is parallel to the waveguide particles 40, the waveguide particles 40 will cut the shock wave into multiple smaller shock waves, accelerating the shock speed and rapidly dispersing it, thereby avoiding the concentration of impact force on a certain point. If the shock wave is not parallel to the waveguide particles 40, the waveguide particles 40 will block the shock wave and change its propagation direction, acting as a spoiler effect. This spoiler effect causes the shock wave to change direction during propagation, thereby facilitating the rapid expansion of the shock wave between the waveguide particles 40 and further dispersing it. In this way, the strip-shaped waveguide particles 40 not only effectively weaken the intensity of the shock wave, but also guide the propagation direction of the shock wave, making it more evenly distributed throughout the chassis structure, avoiding excessive local impact force that can cause structural damage.

[0025] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
