Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a load-bearing mine-protected vehicle body. Background Technology

[0002] Armored vehicles have been threatened by landmines since their inception. Traditional armored vehicles typically have a flat bottom to accommodate the installation and layout of power, transmission, and running systems, as well as the vehicle's shape, internal equipment, and personnel space. However, flat bottoms cannot effectively disperse or deflect explosive shock energy, offering virtually no mine protection. Significantly thickening the bottom plate improves mine protection to some extent, but increases the overall vehicle weight, reduces mobility, and decreases load-bearing capacity. Even with shock-deflecting structures, ordinary armored vehicles are not ideal for mine protection when the deflection angle is large, as the explosive shock wave cannot be deflected sufficiently. When the deflection angle is small, the shock wave deflection effect is better, but the vehicle height and center of gravity increase significantly, affecting handling stability, mobility, and concealment. Therefore, mine-resistant vehicles need to comprehensively consider mine protection performance, mobility, handling performance, and load-bearing capacity, balancing various performance aspects, improving upon the shortcomings of existing armored vehicles, and meeting usage requirements. This necessitates innovative design of existing armored vehicle mine-resistant structures and breakthroughs in various technical challenges. Utility Model Content

[0037] The upper body includes a front wall panel 11, a roof panel 8, a left front side panel 3, a left rear side panel 4, a right front side panel 14, a right rear side panel 13, a weapon ring 7, and a tail plate 9. The front end of the left front side panel 3 connects to the rear end of the left side panel 2 of the engine compartment, the rear end of the left front side panel 3 connects to the front end of the left rear side panel 4, the front end of the right front side panel 14 connects to the rear end of the right side panel 15 of the engine compartment, and the rear end of the right front side panel 14 connects to the right rear side panel 15. The front end of the upper vehicle body, the bottom ends of the left front side panel 3, the left rear side panel 4, the right front side panel 14, and the right rear side panel 13 are respectively connected to the upper ends of the right side panel 10 and the left side panel 12 of the lower vehicle body. The rear ends of the left rear side panel 4 and the right rear side panel 13 are connected to the tail plate 9. The upper ends of the left front side panel 3, the left rear side panel 4, the right front side panel 14, and the right rear side panel 13 are all connected to the roof panel 8. The weapon ring 7 is located on the roof panel 8.

[0038] The vehicle body is divided into three compartments: the power compartment, the passenger compartment, and the transmission compartment. The power compartment is formed by the engine room, the lower body, and the front wall panel 11. The engine room mainly houses the engine, cooling system, intake system, exhaust system, and battery. The passenger compartment is formed by the upper body and the floor. The space inside the passenger compartment mainly houses the instrument panel, seats, electrical equipment, communication equipment, control system, and weapon terminals. The driver's area and the passenger area are connected. The transmission compartment is formed by the floor and the lower body. The transmission compartment mainly houses the transmission, transfer case, drive shaft, fuel supply system, and pneumatic system. The axle and suspension system are located outside the lower body. Heat dissipation vents are set on the outside and top of the left side enclosure 2 and the right side enclosure 15 of the engine room according to the airflow. The lower body has partial protrusions or openings at the engine oil pan, transmission, and transfer case locations, depending on the installation situation. Protective covers are installed at the openings.

[0039] The upper body features a tilted design on the left and right sides of the vehicle body and the driver's window glass. The lower body has partial protrusions or openings at the engine oil pan, transmission, and transfer case locations, depending on the installation situation. The bottom of the vehicle body adopts a double V-shaped structure, with the first V-shaped design at the bottom of the vehicle body and the second V-shaped design at the left side 12 and right side 10 of the lower body, forming a double V-shaped gradient unloading structure at the bottom of the vehicle body. The floor frame 18 is bolted to the floor mounting bracket 17, and the floor panel 19 is bolted to the floor frame 18. All other parts are welded.

[0040] To ensure the vehicle's mine protection capability, the bottom of the vehicle body adopts a double V-shaped structure. Its main function is to increase the occupants' height off the ground and deflect the impact of the explosion. The second-stage V-shaped angle is smaller than the first-stage V-shaped angle, forming a double V-shaped gradient unloading structure at the bottom of the vehicle body. Through diversion unloading and stepped unloading, the impact of the explosion on the whole vehicle is reduced, and the impact energy is reduced to the occupant compartment.

[0041] Furthermore, the V-angle at the bottom of the front V-shaped plate 5 and the rear V-shaped plate 20 is 90° to 150°, the width is 600 mm to 1200 mm, and the height is 200 mm to 500 mm; the V-angle at the bottom of the left side panel 12 and the right side panel 10 of the lower body is 90° to 135°, and the width is 1600 mm to 2200 mm; the left side panel 12, the right side panel 10, the front V-shaped plate 5, and the rear V-shaped plate 20 are all made of high-strength structural steel with a thickness of 10 mm.

[0042] In this embodiment, the high-strength structural steel plate uses existing materials with a strength of 600-1100 MPa, possessing high strength and good toughness. Through bending and forming, it can absorb some of the explosive energy during a landmine explosion through plastic deformation, while ensuring the vehicle body does not crack during the explosion, thus preventing impact penetration. The engine compartment, upper body, and floor materials use ballistic protection materials. These ballistic protection materials are existing materials with a strength greater than 1200 MPa, preventing damage to the vehicle body from bullets, fragments, and explosive spatter. They also absorb some vibration impact, preventing shattering or breakage, thus avoiding personnel injury and secondary effects.

[0043] Furthermore, the bottom of the left side panel 12, the right side panel 10, the front V-shaped plate 5, and the rear V-shaped plate 20 of the lower body are also provided with V-shaped reinforcing ribs of the same angle, and the reinforcing ribs are made of Q355B low alloy structural steel with a thickness of 4 mm.

[0044] Furthermore, the vehicle body has three doors: the left front side panel 3, the right front side panel 14, and the tailgate 9. There are also two escape windows on the roof panel 8, and three observation windows on the left rear side panel 4 and the right rear side panel 13, to meet the requirements for daily use, observation, lighting, and emergency escape.

[0045] In this embodiment, to ensure structural strength during an explosive impact, the lower body is reinforced with V-shaped reinforcing ribs of the same angle. The lower body reinforcing ribs are mainly arranged at the front and rear ends, the front axle suspension, the rear axle suspension, the transmission, and the transfer case, providing localized reinforcement to ensure the rigidity and strength of the lower body and to prevent the rear V-shaped plate from cracking under impact deformation. The upper body weapon rings, escape windows, observation windows, and other openings are reinforced with channel-shaped reinforcing ribs. The reinforcing ribs are made of Q355B low-alloy structural steel with a thickness of 4 mm.

[0046] The embodiments given above are preferred examples of implementing this utility model, and this utility model is not limited to the above embodiments. Any non-essential additions or substitutions made by those skilled in the art based on the technical features of the technical solution of this utility model shall fall within the protection scope of this utility model.
