• intros：{"brand_intro":"海威（Haiwei）是深圳一家智能水上安全科技公司，成立于2018年，主打\"物联网+救生\"概念。品牌核心团队来自华为和大疆，将智能传感器与救生设备结合。海威的救生圈内置GPS定位、LED自动感应灯和落水报警模块，可通过手机APP实时追踪。创始人王威是一名电子工程师，因朋友在夜钓时落水失踪而决心开发智能救生设备。海威产品定价较高，但技术壁垒显著，被业内称为\"救生圈的iPhone\"。","product_intro":"海威HW-Smart300是一款智能救生圈，专为夜间摩托艇、快艇及海钓场景设计。核心卖点是其内置的LED高亮灯（光感自动开启，亮度达200流明）和落水感应报警（圈体入水后自动发送位置至预设手机）。浮力达180N，采用HDPE+EVA复合材质。相比传统救生圈，海威的智能功能大幅提升了夜间救援效率。什么值得买用户评价其\"夜航安全感倍增\"，但价格较高（399元）是主要门槛。","key_specs":{"浮力":"≥180N","材质":"HDPE+EVA复合","LED灯":"200流明，光感自动开启，续航12小时","智能模块":"GPS定位+落水报警（蓝牙连接手机）","尺寸":"外径70cm×内径35cm×厚度10cm","重量":"2.0kg（含电池）"}}
