The invention provides a child safety seat with an intelligent furling device and a pre-tightening control method thereof.The pre-tightening control method comprises the steps that composite motion data of the child safety seat and current rate data of a driving tool are obtained, and a composite collision risk index is dynamically calculated; when the composite collision risk index exceeds a preset safety boundary value, the furling device is controlled to execute a first protection response strategy; the regulation speed limit data of the road section where the driving tool is located is obtained, and when it is detected that the driving tool is in an overspeed driving state or the current speed data is larger than the preset safety speed, the side wing protection device is triggered to be unfolded; and after the first protection response strategy is executed, dynamically adjusting the buffer protection strategy according to the current rate data and the composite motion data. The child seat solves the technical problems that although an existing child seat can reduce most injuries, the child seat can not fix the body of a child passenger violently rushing forwards when encountering high-speed or offset collision, and protection on the passenger is insufficient.

    本发明提供了一种带有智能卷收装置的儿童安全座椅及其预紧控制方法,预紧控制方法包括:获取儿童安全座椅的复合运动数据和驾驶工具的当前速率数据,且动态计算复合碰撞风险指标;当复合碰撞风险指标超出预设安全边界值时,控制卷收装置执行第一保护响应策略;获取驾驶工具所处路段的法规限速数据,当检测到驾驶工具处于超速行驶状态或当前速率数据大于预设安全速率时,触发侧翼防护装置展开;在第一保护响应策略执行后,根据当前速率数据与复合运动数据动态调整缓冲保护策略。本申请解决的技术问题是:现有的儿童座椅虽然能够减少大部分伤害,但在遇到高速或偏置碰撞时,可能固定不住儿童乘员身体的剧烈前冲,导致对乘员的保护不足。
