The invention relates to the technical field of tire inflation and discloses a vehicle-mounted tire inflation device. The device comprises an inflator pump and a transfer gas cavity, the transfer gascavity sleeves a periphery of a round rod which is perpendicular to the wheel and can synchronously rotate along with the wheel; the transfer gas cavity is connected to the vehicle and does not rotatealong with the round rod; and the round rod is provided with a gas inlet and a gas outlet, the gas inlet is covered by the transfer gas cavity, a first gas inlet pipe is arranged between the inflatorpump and the transfer gas cavity, a second gas inlet pipe is arranged between a round rod gas outlet and a tire valve, and a reversing valve is arranged on the first gas inlet pipe and/or the secondgas inlet pipe. The device does not need to be disassembled after being installed on a vehicle, an influence is not generated on operation of the vehicle, and the device can respond and supplement airin time when the tire needs to be inflated no matter in emergency or in case of daily gas loss of the tire; and the device is high in applicability and can be installed on any vehicle with two wheels, three wheels, four wheels and more than four wheels, and when the device is installed on the inner side of the tire, the appearance of the vehicle is not influenced at all.
本发明涉及轮胎充气技术领域,公开一种随车轮胎充气装置,包括充气泵和中转气腔,中转气腔套设在一垂直于车轮且可跟随车轮同步旋转的圆杆外周,中转气腔连接在车辆上且不跟随圆杆转动,圆杆上开设气体通入口和气体排出口,气体通入口被中转气腔覆盖,充气泵和中转气腔之间设有第一进气管,圆杆气体排出口和轮胎气门之间设有第二进气管,第一进气管和/或第二进气管上设有换向阀。装置安装至车辆上后无需拆卸,不会对车辆的运行产生任何影响,无论是应急还是轮胎发生日常的气体损耗,装置都可在轮胎需要充气时及时响应补气;装置适用性强,可装在两轮、三轮、四轮和四轮以上的任意车辆上,装置安装在轮胎内侧时,完全不会影响车辆的外观。
