Embodiment 1

[0038] The wing-span type emergency escape door of large and medium-sized passenger cars of this embodiment is as follows: figure 1 with figure 2 As shown, it includes a door frame 1, a rising window 2 and a pedal 3. The door frame 1 is arranged on the side of the vehicle body, and its bottom is flush with the floor in the passenger car. The rising window 2 is hinged on the top of the door frame 1 , and the pedal 3 is hinged on the bottom of the door frame 1 .

[0039] Such as figure 1 As shown, the emergency escape door is closed when the bus is in normal use, and the rising window 2 and the pedal 3 are folded into the door frame 1 as a part of the bus body.

[0040] Such as figure 2 As shown, during emergency escape, the catch of the locking mechanism 5 is released, the elastic force of the air spring support rod 4 lifts the rising window 2, and the pedal 3 is lowered, and the telescopic plate inside the pedal 3 stretches out thereupon, forming an escape passage. Lock...

Embodiment 2

[0052] In the event of an emergency: the driver presses the emergency button on the control panel, the solenoid valve of the door pump is energized to connect the air circuit between the solenoid valve of the door pump and the air pump, the push rod of the cylinder extends out to push the disc of the linkage mechanism, and the disc drives the pull wire to open the door Lock, the gas spring pushes out, and the safety door opens. At the same time, the vehicle's double-flashing alarm lights, the vehicle's roof-mounted alarm lights, and the built-in voice alarm circuit in the compartment send out an alarm. The whole process takes less than one second.

[0053] The principle of electric control opening is as follows Figure 5 with 6 As shown: the driver presses the emergency door emergency button 19, the control unit 20 connects the emergency door power supply 21 and the door pump solenoid valve 12, and the air pump pushes the push rod of the cylinder 11 to push the turntable 8 cl...

Embodiment 3

[0056] In the event of an emergency, the vehicle circuit fails: open the external safety cover of the manual control valve of the escape door, turn the knob clockwise, the knob will press the air circuit button on the solenoid valve of the door pump through the linkage mechanism to connect the air circuit, and the cylinder push rod will extend Push the disk of the linkage mechanism, the disk drives the pull wire to open the door lock, the gas spring pushes out, and the safety door opens. The whole process takes less than a second.

[0057] The principle of manual opening on the outside of the box is as follows: Figure 5 with Figure 7 As shown: press the red button on the emergency valve cover above the emergency door to trigger the switch 14, turn on the alarm device of the front control unit, prompt the driver that the emergency valve is opened, twist the control switch 13 clockwise, and the linkage shaft 13-1 The shifting block 13-2 toggles the intake switch on the door ...

Abstract

The invention discloses a wing-span type emergency escape door for a large and medium-sized passenger car, which comprises a door frame, a rising window and a pedal. Hinged to the top of the door frame; when the bus is in normal use, the rising window and the pedal are closed into the door frame as a part of the bus body; during emergency escape, the pedal is turned down along the hinge, and the rising window rises to form an escape passage. The invention has the advantages of low manufacturing cost, convenient opening, extremely short use time, practicality and reliability.

Description

technical field [0001] The invention relates to an escape device installed on a vehicle, which is used for emergency evacuation of people in the compartment when an emergency occurs in the vehicle, in particular to a wing-span type emergency escape door device suitable for large and medium-sized passenger vehicles. Background technique [0002] In recent years, due to various reasons, public transport vehicles have experienced many major property losses or mass casualties, resulting in irreparable and serious consequences. How to improve the safety of public transport vehicles, so that the occupants can escape quickly when danger occurs, and avoid or reduce casualties to the greatest extent, is a major problem that public transport vehicles are facing and needs to be solved urgently. The vehicle body of large and medium-sized buses is generally a fully fixed installation structure, and there are only two or three doors for passengers to get on and off. Restricted by factors...
