An emergency control system for a passenger door of a passenger vehicle

Abstract

An emergency control system for passenger doors in a bus includes a first two-position three-way emergency valve and a second two-position three-way emergency valve. The first two-position three-way emergency valve is connected to a door pump quick-release valve, which is connected to a door pump cylinder via a door pump solenoid valve. The first two-position three-way emergency valve is installed on the passenger door panel, the passenger door lock, or the external trim of the passenger door. The second two-position three-way emergency valve is located inside the vehicle. Compared with the prior art, this utility model has the following advantages: This utility model provides a passenger door emergency control system based on an integrated emergency valve, a passenger door lock, and a quick-release valve. Through innovative design, a two-position three-way valve is used to provide pilot air to control the quick-release valve for rapid venting, and an electrical signal is used to control the quick-release valve to reset during reset.
