Bus escape window capable of sliding down automatically

Abstract

The invention discloses a bus escape window capable of sliding down automatically, and the problems that in the prior art, centralized control and automatic operation cannot be achieved, efficiency islow, and lanes are occupied in the vehicle window gliding process are solved. The bus escape window is characterized in that a guide wheel assembly, a hinge and a connecting rod are arranged on the car window; a window frame is connected with an air cylinder; a piston sleeve is arranged in the air cylinder; a retainer is arranged in the piston sleeve; a radial round hole communicated with an axial blind hole is formed in the retainer; a first spring and a separation rod are arranged in the axial blind hole; a steel ball is assembled in the radial circular hole; a blind threaded hole is formedunder the cylinder body of the air cylinder; a pipe joint is in threaded connection in the blind threaded hole; a bent line track formed by an inner side guide groove, an inclined guide groove and anouter side guide groove is arranged on a wind frame stand column; and a handheld button is installed on the back end of the piston sleeve. The bus escape window has the advantages that centralized control, automatic operation and compatible manual operation can be achieved, operation is easy and convenient, the bus escape window is tightly attached to the outer side of a vehicle body in the sliding process of the vehicle window, overturning is avoided, and a lane is not occupied.

Description

technical field [0001] The invention belongs to the technical field of buses, in particular to an automatic sliding down escape window of a bus. Background technique [0002] Since fires, traffic accidents and other emergencies occur frequently during the operation of buses, which may endanger the personal safety of passengers in serious cases, in order to ensure that passengers can escape from the bus in time when an accident occurs and reduce the harm of accidents, In the prior art, general buses all have escape hammers, but the bus window glass is generally made of toughened glass, the window is hard, has good mechanical properties and impact resistance, and the four corners of the window glass must be knocked. The glass may be smashed, and even so, it is difficult to hit it with one blow, and the broken glass takes a long time, losing precious escape time. [0003] Some buses are equipped with an electric breaker. In a critical moment, the bus driver presses the button ...

AI Technical Summary

Problems solved by technology

[0006] The problem with the above two technical solutions is that they cannot realize centralized control and automatic operation, and in case of an emergency, "a bus window emergency escape quick opening system" requires passengers to rotate the locking knobs one by one , and push the window outward by hand to release the fixed constraints on the window, so that the window can automatically slide down under the guidance of the guide grooves on both sides. The efficiency is low and the window is opened slowly. In an emergency, the passengers are in a panic , and cannot operate, then the emergency escape quick opening system cannot be opened, and the vehicle window can not be quickly opened to escape; "a kind of sliding vehicle escape window" is under normal conditions, and the emergency switch and the locking piece are fixed. One pulley is located in the arc-shaped guide rail, the second pulley is located in the straight track, and the spring is compressed by the sliding window; in case of emergency, passengers need to unscrew the emergency switch to disengage the locking plate, and the force of spring rebound makes the sliding window The body moves outward as a whole, the sliding form slides down by gravity, the first pulley falls along the arc guide rail and the straight guide rail, and the straight track falls along the second pulley, so as to ensure that the sliding form slides down according to the established path, and there is also low efficiency. The window is slow, and in an emergency, passengers are in a state of panic and cannot operate, so the sliding vehicle escape window described in this utility model cannot slide down, and it is impossible to quickly open the window to escape
