Coast Guard rescues 4 Canadians from capsized catamaran off North Carolina_我的网站

一 |     8月26日消息，近期，国家知识产权局公示了比亚迪批量申报的多项轮胎相关发明专利，覆盖可变电控轮胎骨架、四轮独立充放气、轮胎内壁光栅传感、双层防爆多气腔等多个方向，整套技术方案形成完整自研体系。     这套方案中，轮胎内壁光栅传感专利通过轮胎内壁全覆盖式柔性光栅贴片，消除传统胎压监测的形变盲区，同步采集胎压、温度、轮胎形变等多维状态数据，为胎压调节提供感知输入。    Four Canadian mariners were rescued by the U.S. Coast Guard after their boat capsized 140 miles off the shore of Wilmington, North Carolina, the USCG said in a release.The Coast Guard Command Center received an emergency signal at 12:18 p.m. from Moon Dragon, a catamaran off the coast of North Carolina Sunday afternoon.Once at the scene, an airplane crew found the capsized catamaran and a covered life raft. All four aboard the Moon Dragon were found safe in the raft and were uninjured, using a radio to call for help.The mariners were saved by a Coast Guard Jayhawk helicopter crew and sent to Air Station Elizabeth City.The four aboard the catamaran told the Coast Guard that their hatches broke on both the port and starboard sides of the vessel, causing the catamaran to flood and forcing them to abandon ship.。

二 |          与之配套的是主动四轮独立充放气系统专利。简单来说，这套系统可实现无需下车，车辆对每个轮胎单独完成充气、放气，四轮可同步操作，互不干扰。     过往主动充放气技术多应用在军用越野轮式装甲车，大多采用车桥控制模式，前桥两轮、后桥两轮统一调压，或是管路共用，轮胎只能够依次调压。    路虎早期中央充放气专利同样以桥控为主，无法做到每个车轮充放气通道完全独立并行，大多只能整车统一升压降压，单轮独立调节能力有限。          比亚迪这套充放气系统主要由充气阀组、放气阀组两部分构成。充气阀组接入车载气源，分出多路出气口分别对接4条轮胎，每一路管路都配有独立电磁阀，可单独控制对应轮胎充气。

三 |     放气阀组为每条轮胎配备独立放气电磁阀，排气口直连外界大气，需要给某一轮胎降压时，仅开启对应阀门即可向外排气。每条轮胎充、放气通路均可单独通断，支持多轮同步充放气，调节效率大幅提升。     两套专利相互配合，车辆依靠光栅贴片识别路面带来的轮胎状态变化，充放气系统据此动态调整各个车轮胎压。沙地、泥地越野场景下，系统可以降低胎压扩大轮胎接地面积。    行驶至铺装路面，自动将胎压恢复至标准数值；遇到轮胎慢撒气故障，也能够自动补压，不必立刻靠边停车，全程无需人工干预，优化轮胎抓地性能。
