Problems solved by technology

[0005] Secondly, the windows are at a certain height from the floor inside the car, and the height of the vehicle’s chassis is higher than the road / ground outside the car. In an emergency, it is difficult for passengers to climb through the windows and jump to the ground in an orderly manner, because it is easy to step on them due to congestion cause secondary damage

Embodiment 1

[0039] The closing state of the unfolded emergency escape door of the large and medium-sized passenger car in this embodiment is as follows: figure 1 As shown, the door frame 1 is installed on the left side of the passenger car, and at the same time it serves as the dividing line of the adjacent windows. When the passenger car is in normal use, the emergency escape door is closed, the rising window 2 is closed into the door frame 1 as a part of the passenger car window, and the pedal 3 is closed. Into door frame 1 as part of the passenger car skin. The dividing line between the rising window 2 and the pedal 3 just in time is also the dividing line between the car window and the skin, and the bottom of the door frame 1 is flush with the lower edge of the vehicle body skin. In this way, the overall appearance of the passenger car will not be affected after the escape door is installed, and it is skillfully integrated to facilitate the production of body advertisements.

Embodiment 2

[0053] 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.

[0054] The principle of electric control opening is as follows Figure 5 and 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 clo...

Embodiment 3

[0057] 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.

[0058] The principle of manual opening on the outside of the box is as follows: Figure 5 and 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 p...

Abstract

The invention discloses an expansion type emergency escape door for large and medium passenger vehicles, comprising a door frame, a rising window and a pedal, wherein the door frame is arranged on the side face of a vehicle body; a driving bent arm and a driven support arm which are used for translating up and down along the outer side of the vehicle body are mounted between the rising window and the door frame; and the pedal is articulated to the bottom of the door frame. When a passenger vehicle is in normal use, the rising window and the pedal are folded in the door frame, the rising window serves as a part of a vehicle window, and the pedal serves as a part of vehicle body skin; and in emergency escape, the pedal is turned downwards along a hinge, and the rising window is translated upwards along the outer side of the vehicle body, thereby forming an escape passage. The expansion type emergency escape door is low in manufacturing cost, convenient in opening and very short in opening time and is practical and reliable.

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, and specifically designs a deployable 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 fac...
