Abstract
Description
Technical Field
[0001] This utility model relates to the field of special vehicle technology, and in particular to a fire truck. Background Technology
[0002] As core equipment in the emergency rescue field, existing fire trucks primarily undertake firefighting and rescue missions. Their overall structure is typically based on a specialized chassis with high load-bearing capacity, integrating key components such as a crew compartment, equipment boxes, water or foam storage tanks, and fire pumps to provide power for firefighting. These components work together to meet the needs of emergency scenarios. However, in long-term practical application, the design flaws of traditional fire trucks have gradually become apparent, making them difficult to adapt to the actual needs of efficient rescue.
[0003] From a structural assembly perspective, traditional fire trucks mostly use welded connections for their core components. While this rigid connection ensures basic stability, it results in a fragmented overall structure and a complex assembly process. Not only does each component need to be welded individually during production, but disassembling and replacing damaged parts during later maintenance also requires cutting the welds first. This increases maintenance time and costs and hinders modular production and rapid iterative upgrades. Regarding driving and operational efficiency, traditional models often have a separate cab and rear work compartment, creating a physical partition. Firefighters must frequently get in and out of the vehicle to retrieve and load equipment and adjust parameters, especially in emergency rescue scenarios, where this repeated movement directly delays response times.
[0004] Issues regarding space utilization and safety / comfort are equally significant: the equipment compartments mostly feature fixed partitions, lacking flexible zoning, resulting in a large amount of unused space when storing some equipment, while frequently used tools are difficult to access quickly due to cluttered layouts; the crew compartment, limited by its enclosed structure, suffers from poor ventilation, easily leading to stale air during prolonged duty, and in emergencies, escape relies solely on the vehicle doors, resulting in a single escape route and posing a safety hazard. Furthermore, the vehicle's control systems are scattered across different areas, requiring firefighters to move between the driver's cab and the work area, hindering unified control and further reducing operational convenience. Therefore, developing a new type of fire truck with a compact structure, scientific layout, modular assembly capabilities, and a through-type crew compartment has become an urgent need to improve vehicle overall performance, ensure rescue efficiency, and enhance driver and passenger safety.
