Description

Anti-explosion shock wave device for motor vehicles

technical field

The invention belongs to the technical field of protective devices for motor vehicles, in particular to an anti-explosion shock wave device for motor vehicles that can effectively resist damage to vehicles and occupants caused by shock waves generated by the explosion of landmines or random explosive devices.

Background technique

During the wars in Iraq and Afghanistan, various transport vehicles of the United States and its allies were often attacked by landmines and improvised explosive devices (IEDs), which seriously threatened the lives of a large number of battlefield personnel and caused significant loss of life and property. In response to the needs of international peacekeeping operations and the increasingly serious threat of terrorism, Western countries have paid attention to the research on vehicle anti-kinetic shrapnel and landmine threats to occupants since the end of the 1990s, and have formulated corresponding standards, such as NATO's STANAG4569, the United States' RSA-MIL-STD-37, etc. In the field of car body anti-kinetic energy shrapnel and vehicle bottom lightning protection, through the development of new composite materials and special vehicle bottom structures, South Africa and other countries have obtained fruitful research results, and products using this result have been put into the battlefields of Iraq and Afghanistan Use, such as the RG-33 series mine-resistant ambush vehicles of the US military, the "Viper" high-mobility vehicles produced by OSHKOSH Truck Company, and the G-Wagon280CDI light armored patrol vehicles produced by Mercedes-Benz. Throughout this type of vehicle, the body uses composite materials with anti-ballistic properties and a V-shaped structure that is conducive to dispersing the blast shock wave. However, this V-shaped structure sacrifices the minimum ground clearance of the vehicle and reduces the passing speed of the vehicle. performance.

The overall armor protection level of modern armed vehicles is getting higher and higher, and it can already defend against most anti-vehicle mines or improvised explosive devices (IEDs). The damage caused is still on the rise. This is because when tanks and armored vehicles are subjected to such attacks, many casualties are not caused by armor breakdown, but by the detonation impact transmitted to the human body through vehicles, seats and other structures. caused by energy.

Therefore, the problems existing in the prior art are: the anti-explosion shock wave capability of the motor vehicle is insufficient, and the safety protection performance is insufficient.

Contents of the invention

The object of the present invention is to provide an anti-explosion shock wave device for a motor vehicle, which can improve the anti-explosion shock wave capability of the vehicle without reducing the maneuverability and passing performance of the vehicle.

The technical solution to realize the object of the present invention is: a motor vehicle anti-explosion shock wave device, comprising an upper protective plate and a lower protective plate arranged in parallel, between which a plurality of protective plates for absorbing , The energy-absorbing mechanism that cushions the blast shock wave.

Compared with the prior art, the present invention has significant advantages:

1. Improve the anti-explosion shock wave function of the vehicle: the energy-absorbing mechanism installed between the two protective plates can effectively convert the huge energy generated by the explosion into the elastic potential energy of the spring; at the same time, the two protective plates can effectively block the explosion generated by the explosion. Kinetic energy shrapnel, so the present invention can greatly reduce the damage of explosion to vehicles and occupants.

2. Does not reduce the maneuverability and passing performance of the vehicle: the present invention is different from the previous V-shaped plate bottom protection mechanism, does not sacrifice the minimum ground clearance of the vehicle, greatly improves the passing performance of the vehicle, and has a simple structure, which is easy to implement and install.

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Description of drawings

Fig. 1 is a top view of the anti-explosion shock wave device for a motor vehicle of the present invention.

Fig. 2 is a sectional view along line A-A of Fig. 1 .

Among the figure, 1 upper protective plate, 2 lower protective plates, 3 energy absorbing mechanisms, 31 bolts, 32 nuts, 33 upper spring draw-in slots, 34 lower spring draw-in slots, 35 springs, 36 upper rubber pads, 37 lower rubber pads.

Detailed ways

As shown in Figure 1, the anti-explosion shock wave device for a motor vehicle of the present invention includes an upper protective plate 1 and a lower protective plate 2 arranged in parallel, and multiple 3. The energy-absorbing mechanism for buffering the blast shock wave. The upper fender 1 can also be directly the vehicle floor.

The energy-absorbing mechanism installed between the two protective plates can effectively convert the huge energy generated by the explosion into the elastic potential energy of the spring; at the same time, the two protective plates can effectively block the kinetic energy shrapnel produced by the explosion, so the present invention can greatly reduce The explosion caused damage to the vehicle and its occupants.

Without sacrificing the minimum ground clearance of the vehicle, the passing performance of the vehicle is greatly improved, and the structure is simple, easy to realize and install.

All of the following are shown in Figure 2.

The energy-absorbing mechanism 3 includes a bolt 31, a nut 32, an upper spring slot 33, a lower spring slot 34, and a spring 35, and the bolt 31 passes through the upper protective plate 1, the upper spring slot 33, the spring 35, and the lower spring slot in turn. The spring clamping groove 34 and the lower guard plate 2 are connected with the nut 32 behind, and the guard plate 1 and the lower guard plate 2 are connected into a whole, and the two ends of the spring 35 are respectively fixed in the upper spring clamping groove 33 and the lower spring clamping groove 34 .

The bolt 31 not only acts as a guide to the spring 35, but also plays a role in connecting the vehicle floor or the upper fender 1 and the lower fender 2 together.

Upper spring retaining groove 33, lower spring retaining groove 34 are respectively welded on upper protective plate 1 and lower protective plate 2, and the two ends of spring 35 are respectively fixed in the groove of upper spring retaining groove 33 and lower spring retaining groove 34. In this way, when the spring is deformed, its two ends are still confined in the groove without horizontal displacement.

As an improvement, an upper rubber pad 36 is further provided between the upper protective plate 1 and the upper spring retaining groove 33 of the energy absorbing mechanism 3 .

As a further improvement, a lower rubber pad 37 is further provided between the lower spring clamping groove 34 of the energy absorbing mechanism 3 and the lower protective plate 2 .

The rubber pad is a damping element, which can absorb energy and effectively reduce the damage caused by the impact to the protective plate.

The spring 35 is a metal spring. Of course, other springs with the same performance can also be used.
