Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle riot control, and more specifically, relates to a riot-proof body-in-white side panel structure and an assembly method thereof. Background Art

[0002] With the rapid development of society and the increasing demand for public safety, police riot control vehicles, as crucial equipment for public security departments responding to emergencies and handling mass public security incidents, play an irreplaceable role in maintaining social stability and protecting the personal safety of law enforcement personnel. When faced with complex scenarios such as violent conflict, projectile attacks, or threats from small arms, the structural strength, protective performance, and maneuverability of police riot control vehicles directly determine their tactical effectiveness. Currently, common police riot control vehicle protective structures primarily include two options: one is the armor-mounted modification, which involves adding detachable armor modules to ordinary vehicles; the other is the integrated welding of thick armored steel plates, which uses thicker armored steel plates directly to form the outer layer of the vehicle body. However, in actual use, the explosion-proof structures of existing police riot control vehicles still have many shortcomings.

[0003] To improve the protective capabilities of police riot control vehicles, existing technologies primarily attempt to optimize material selection and structural design. In terms of materials, the traditional approach is to use a large amount of high-hardness bulletproof steel plates as outer panels to protect against the impact of bullets or fragments. This material has high penetration resistance and can meet basic protection requirements to a certain extent. In addition, some improved design solutions incorporate composite materials or multi-layer structures, attempting to enhance the overall protective effect through the synergistic effect of different materials. In terms of structural design, existing technologies often use a method of overlapping curved pipes to construct the vehicle body frame, and weld armor steel plates to the outer layer to form a closed protective structure. This structural form improves the rigidity and local impact resistance of the entire vehicle to a certain extent. At the same time, to facilitate production and maintenance, some products adopt a modular design concept, making the armor components somewhat replaceable, thereby extending the service life of the vehicle and reducing subsequent maintenance costs.

[0004] Although existing technologies have made certain efforts at the material and structural levels, their inherent defects still make it difficult to meet the higher requirements of police riot control vehicles for modern law enforcement tasks. For example, the extensive use of bulletproof steel plates has led to a significant increase in the weight of the entire vehicle, which not only increases fuel consumption and chassis load, but may also affect the vehicle's maneuverability and trafficability, especially when driving on narrow urban roads or complex terrain. In addition, the external bulletproof steel plates have poor plasticity, which limits the diversity of body shapes, making the entire vehicle appearance relatively bulky and lacking a streamlined design, which is not conducive to improving aerodynamic performance. Secondly, in the traditional process of using arc tubes to overlap and weld armored steel plates, since the welding quality is greatly affected by the process level, the joints are prone to become structural weak points, which may break or fall off when subjected to high-intensity impact, thereby reducing the overall protection effect. In addition, the arc tube overlap structure itself has certain limitations in spatial layout, and there may be blind spots in certain corners or seam areas. Summary of the Invention
