Description

Technical Field

[0001] This application relates to the field of emergency rescue equipment technology, specifically a towable multi-functional emergency vehicle. Background Technology

[0002] With the increasing frequency of emergencies such as natural disasters, power outages, and outdoor rescues, the demand for mobile emergency power supply and rescue equipment is growing. Towable emergency vehicles, due to their high mobility and rapid deployment, have become core equipment for providing on-site support in areas such as power, lighting, and communication. Currently, the mainstream solution integrates generator sets, energy storage devices, control units, and emergency tools into a closed trailer body to meet the needs of various rescue scenarios.

[0003] Currently, most towable emergency equipment adopts a closed enclosure structure. While this offers advantages such as high equipment integration and convenient transportation, it still suffers from the following significant drawbacks: high-power equipment such as generators and inverters generate high temperatures during operation, and the closed enclosure relies solely on a few ventilation holes for passive heat dissipation. In high-temperature environments, continuous full-load operation of the equipment can easily trigger overheat protection shutdowns, severely impacting power supply stability. Forcibly adding ventilation holes, however, reduces dustproof and waterproof performance, creating a design contradiction.

[0004] Existing enclosures mostly use top-mounted ventilation openings or side-opening doors. In heavy rain or high humidity environments, rainwater can easily enter the equipment compartment through ventilation gaps, leading to short circuits in the control circuits and battery leakage.
