Embodiment

[0017] Such as figure 1 , figure 2 As shown, the bus door emergency escape opening system provided by the present invention is to add a mechanism for quickly driving the door to open when an emergency occurs on the original door driving cylinder block 3 . Specifically, it is composed of a connecting rod mechanism and a soft connection pulling device. The connecting rod mechanism includes a rocker, a connecting rod and a sliding sleeve. The connecting rod mechanism uses the original cylinder body 3 as the base of the driving mechanism. The driving mechanism is symmetrically designed and distributed in the cylinder body. Both sides constitute the main body mechanism of the rocker slider with the connecting rod 5 as the driving element. One end of the rocker 4 is hinged to the tail of the cylinder block 3, the other end is hinged to the connecting rod 5, the connecting rod 5 is hinged to the sliding sleeve 6, and the sliding sleeve 6 is set on the end of the cylinder rod to pus...

Abstract

An emergency escape opening system for a bus door comprises a connecting rod mechanism and a soft connecting pulling device, wherein the connecting rod mechanism comprises a rocker, a connecting rod and a sliding cover, an air cylinder body is taken as a machine seat by the connecting rod mechanism and is symmetrically arranged at the tops of two sides of the air cylinder body axis, a connecting rod (or the rocker ) is taken as a driving member, and a pulling rope in the soft connecting pulling device is connected with the driving member in the connecting rod mechanism. When emergency occurs, a passenger pulls the pulling rope so that an exhaust valve is driven to open, the connecting rod mechanism is driven, and then an air cylinder piston is driven to open the door in sequence.

Description

technical field [0001] The invention belongs to a vehicle door driving device capable of quickly opening the vehicle door to enable drivers and passengers to escape when a bus emerges in an emergency, and particularly relates to a mechanism for driving the vehicle door to open. Background technique [0002] At present, when the bus is in a sudden emergency, the way to open the door to allow passengers to escape is to install a rotary emergency switch on the car body above the door. To open the door, use the cylinder to ensure that the electrical circuit system can also be used normally. to drive the door open. When an emergency occurs and the electrical appliances and gas system fail, even if the emergency switch is rotated, the closed door will not be opened automatically. Contents of the invention [0003] The invention solves the problem that the doors of the existing buses cannot be opened automatically in an emergency situation, and provides an emergency escape openi...
