The invention discloses an air charging device of an automobile safe inflatable curtain. The device comprises an electromagnetic isolation box and air bags, wherein an air outlet pipe is arranged at the lower end of the electromagnetic isolation box, a distributor is arranged on the air outlet pipe, air outlet mouths are arranged on the side wall of the distributor, air guide pipes are installed on the air outlet mouths, the air guide pipes are connected with the multiple air bags, the upper and lower ends of each two adjacent air bags are connected through connecting parts, air generators arefixed to the end, close to the air outlet pipe, of the interior of the electromagnetic isolation box though fixing garter springs, and a storage battery is arranged at the other end of the interior of the electromagnetic isolation box. The device has the advantages that by means of the electromagnetic isolation box, it can be avoided that normal work of the safe inflatable curtain is interfered by external electromagnetic signals; meanwhile, the multiple air generators can fast generate a lot of air for air charging, so that the safe inflatable curtain is filled with the air fast; moreover, the air in the air bags can be used for respiration, so that the device is convenient to use in an oxygen-deficient environment, and the safety of an automobile is improved.
