Upper-layer safety escape device for city double-decker bus

Abstract

The invention discloses an upper-layer safety escape device for a city double-decker bus. The upper-layer safety escape device comprises a safety door arranged at the back of the upper layer of the double-decker bus and an inflatable escape air-cushion arranged behind the safety door; and the safety door is provided with a drawbar lock switch mechanism. The inflatable escape air-cushion is connected with a pressure switch through an air pipe four; the pressure switch is connected with an air reservoir through an air pipe three; when the pressure switch is in a compaction state, an air path isclosed; and when the safety door is opened and the pressure switch is loosen and opened, the air path is in an opening state. The drawbar lock switch mechanism is used by a person in the bus to open the safety door in an emergency situation, or the safety door is opened by a safe door electric control button on an instrument panel inside the bus. According to the upper-layer safety escape device,when escape is needed in case of a fire or an unexpected situation, passengers in the bus can escape along the exit opened by the escape safety door and safely fall on the inflatable escape air-cushion; the rapid and safety escape of the upper-layer passengers of the city double-decker bus is solved.

Description

technical field [0001] The invention relates to a double-decker passenger car, in particular to a safety escape device for an upper layer of an urban double-decker passenger car. Background technique [0002] At present, there are no safety doors or other escape devices on the upper floors of existing double-decker buses in cities. The means of escape are too slow and inefficient. Moreover, due to the high height of the double-decker car, the lower edge of the escape window on the upper floor is at least about 3 meters away from the ground. When passengers on the upper floor escape, if they jump from a height of about 3 meters, fractures or even life-threatening will occur, which is not conducive to the safe escape of passengers. According to the GB 13094-2017 "Safety Requirements for Passenger Car Structures", at least one escape exit on the upper deck of a double-decker bus is located at the rear. Therefore, the problem of safe escape from the upper deck of urban double-...
