摘要： 为探究儿童骑行电动玩具车的火灾危险性和燃烧规律，分别对玩具车零部件和整车进行了燃烧性能试验。测试了玩具车中使用的各类非金属材料的燃烧特性，包括氧指数、引燃温度、引燃时间、热释放速率、发烟量和燃烧产物中的毒气成分，以及整车燃烧的热释放速率、热释放总量和燃烧温度。试验结果表明：该款儿童骑行电动玩具车具有较高的火灾风险性，车头套及车身外套的氧指数为18.8%，引燃温度为283 ℃；车辆线路短路后15 s出现了明火，整车起火后热释放速率峰值为755.012 kW，热释放总量为192.50 MJ。通过本次试验研究，归纳总结了类似独立电源设备的火灾危险性分析流程，为相关设备的火灾调查工作提供了技术支持。

Abstract: To investigate the fire hazards and combustion patterns of children's electric toy vehicle, combustion performance experiments were conducted on vehicle components and the complete vehicle. The combustion performance experiment of non-metallic materials used in the vehicle were tested, including oxygen index, ignition temperature, ignition time, heat release rate, smoke production, and toxic gas; the heat release rate, total heat release amount, and combustion temperature of the entire vehicle combustion were tested, too. The experimental results show this children's electric toy vehicle has a high fire risk, with an oxygen index of 18.8% for the front cover and body cover, and the ignition temperature is 283 ℃; after a short circuit in the vehicle wire for 15 seconds, an open fire appeared, and the peak heat release rate of the complete vehicle was 755.012 kW, with a total heat release of 192.50 MJ. Through this experimental study, the fire hazard analysis process of similar independent power supply equipment is summarized, which provides technical support for the fire investigation of related equipment.
