The invention discloses a vehicle-mounted box type rodless ejection device, and belongs to the field of spaceflight equipment ejection. The device comprises a launching box, a left cylinder, a right cylinder, a tray, an upper guide rail, a lower guide rail, two groups of sliding blocks, an aircraft and a gas cylinder. The launching box is a square launching box, multiple sections of square reinforcing ribs are distributed on the outer side of the launching box, and the launching box wraps the internal aircraft, the air cylinder, the guide rail sliding block and other components to isolate the external environment. The air cylinder structure comprises an external reinforcing frame, a cylinder barrel, a buffering device, a pressure relief hole and an air inlet. The tray comprises a tray main body for lifting the aircraft in the middle, a piston, a sealing ring, a sealing steel belt and a power output arm. The lower guide rail downwards extends out of the launching box body to be combined with the erecting bracket, and is fixedly connected with the frame through the front end locking device, so that the overall strength of the frame is improved. Compressed air is selected as an ejection medium. The device has the characteristics of box-type launch aircraft protection, quick response and convenience in maintenance, and also has the advantages of long effective stroke, good compatibility and adaptability and low thermal protection requirement of rodless launch.
