The invention discloses an air valve, a tire pressure adjusting method and a tire pressure adjusting device, relates to the technical field of automobiles, and can reduce the probability of collision between a vehicle and an object. The air valve comprises an air nozzle. A valve core and a fixed iron core are arranged in the air tap, a coil is wound at the bottom outside the air tap, the fixed iron core is fixed at the bottom inside the air tap, and the coil comprises an interface for connecting a power supply. The valve core comprises a valve core shell, a movable iron core and a spring connected with the movable iron core, and an air hole is formed in the top of the valve core shell. And when the coil is not electrified, the spring generates upward acting force on the movable iron core, so that the movable iron core is connected with the bottom of the valve core shell. When the coil is powered on, the bottom of the valve core shell is separated from the movable iron core, and air in the air nozzle enters the valve core through the bottom of the valve core shell and is exhausted through an air hole in the top of the valve core shell.

    本申请公开了气门、胎压调整方法及胎压调整装置,涉及汽车技术领域,能够降低车辆与物体发生碰撞的概率。该气门包括气嘴。气嘴内部设置有气门芯和定铁芯,气嘴外部的底部缠绕有线圈,定铁芯固定在气嘴内部的底部,线圈包括用于连接电源的接口。气门芯包括气门芯外壳、动铁芯和与动铁芯连接的弹簧,气门芯外壳顶部设置有气孔。线圈未通电时,所述弹簧对所述动动铁芯产生向上作用力,使得所述动铁芯与气门芯外壳底部相连。线圈通电时,气门芯外壳底部与动铁芯分离,气嘴内部的空气通过气门芯外壳底部进入气门芯并由气门芯外壳顶部的气孔排出。
