The invention discloses a self-power-generation tire state monitoring device, and relates to the field of automobile safety, the self-power-generation tire state monitoring device comprises a hub, a mounting bolt is arranged on the hub, a plurality of reinforcing ribs distributed circumferentially are arranged between the hub and the mounting bolt, and a monitoring sensor is arranged on the hub. A protection mechanism is arranged between the monitoring sensor and the hub, and a self-power-generating mechanism is arranged on the hub. When the automobile is started to run, the hub rotates, the self-power-generating mechanism is driven by the hub to generate electric quantity and transmits the electric quantity to the monitoring sensor, the monitoring sensor transmits a monitored tire pressure signal to a central control of the automobile, the protection mechanism protects the monitoring sensor, and meanwhile the protection mechanism also plays a role in supporting the self-power-generating mechanism. Therefore, the monitoring sensor on the hub can run without a battery, the possibility of replacing the battery of the monitoring sensor by disassembling a tire back and forth is reduced, and meanwhile, the monitoring sensor is protected by the protection mechanism.
本申请公开了一种自发电轮胎状态监测装置,涉及汽车安全领域,包括轮毂,所述轮毂上设置有安装螺栓,所述轮毂与安装螺栓之间设置有若干个呈圆周分布的加强筋,所述轮毂上设置有监测传感器,所述监测传感器与轮毂之间设置有保护机构,所述轮毂上设置有自发电机构。当车辆启动行驶过程中,轮毂转动,自发电机构在轮毂的带动下产生电量并传递给监测传感器,监测传感器将监测到的胎压信号传递给汽车的中控,保护机构对监测传感器进行保护,同时保护机构还对自发电机构起到支撑作用,从而能够让轮毂上的监测传感器能够不需要电池就能运行,减少来回拆卸轮胎更换监测传感器电池的可能,同时保护机构对监测传感器提供保护。
