Water circulation safety belt system and adjusting method

The invention relates to the technical field of vehicle part devices and control methods, in particular to a safety belt temperature and buffer pressure adjusting method and device. The device comprises a water bag, a water pump, a temperature acquisition unit, a pressure acquisition unit, a temperature adjusting unit and a controller, and the controller is in data connection with the temperature acquisition unit, the pressure acquisition unit, the temperature adjusting unit and the water pump. The controller controls the temperature adjusting unit to adjust the temperature of liquid in the water bag through data transmitted by the temperature acquisition unit, and controls the water pump to adjust the flow of circulating water in the water bag through data transmitted by the pressure acquisition unit temperature acquisition unit to change the pressure between a safety belt and a driver and passengers. The adjusting method is extremely simple, the comfort of a driver and passengers can be improved through tem
