The invention discloses a fully-automatic special covering 
canopy for a car, which is mainly composed of a plastic housing, a small electric air-inflation and air-extraction dual-purpose 
machine, a 
remote control signal receiver, two upper square chemical fabrics, four telescopic thin 
alloy sleeves, a fixing device, etc. An unfolding 
signal is transmitted to the special covering 
canopy disclosed by the invention by virtue of a remote controller; the small electric air-inflation and air-extraction dual-purpose 
machine is used for inflating air into the contracted thin 
alloy sleeves via air tubes respectively; two of the 
alloy sleeves stretch forwards, and the other two of the alloy sleeves stretch backwards; the two upper square chemical fabrics are connected with the alloy sleeves via a plurality of connection points; and the chemical fabrics are unfolded to cover the upper part of the car during the stretching process of the alloy sleeves. In the case that the car has no need to be covered, a folding 
signal is transmitted via the remote controller; the small electric air-inflation and air-extraction dual-purpose 
machine is used for extracting the air in the stretched thin alloy sleeves; the alloy sleeves synchronously retreat into the final section of hollow tube; and the chemical fabrics is folded and contracted in the plastic housing. The special covering 
canopy disclosed by the invention is fixed at the middle of a car roof, and has no influence on the structure and the safety of a car body.
