Rapid window breaking mechanism for bus

Abstract

The invention discloses a rapid window breaking mechanism for a bus. The rapid window breaking mechanism for the bus comprises a hydraulic driving assembly, bases, a hydraulic swing arm, a first flange, a second flange, a driven swing arm, a first hammer head, a second hammer head, a third hammer head and a fourth hammer head, the bases are distributed on the periphery of window glass, the two ends of a first rotating shaft are rotationally mounted on the two bases in front through bearings, the two ends of the first rotating shaft are fixedly sleeved with the hydraulic swing arm and the firstflange respectively, the front end of the hydraulic swing arm is fixedly connected with the first hammer head, and the front end of the first flange is fixedly connected with the second hammer head.According to the rapid window breaking mechanism for the bus, by means of the hydraulic driving assembly, the driving force of a linear motor is amplified, the force transmitted to the hydraulic swingarm meets the requirement, the matching requirement of the driving force of a power source (the linear motor) is lowered, it is guaranteed that the mechanism is triggered when fire happens, the bus falls into water or the mechanism is manually opened, the window breaking function is automatically, conveniently and rapidly achieved, and the safety of passengers in an emergency is ensured.

Description

technical field [0001] The invention relates to the technical field of rapid bus window breaking, in particular to a bus rapid window breaking mechanism. Background technique [0002] In recent years, the number of family cars has increased year by year, and urban congestion has become more and more serious. In order to alleviate urban congestion, local governments encourage citizens to use public transportation to travel. Public transportation has become an efficient, economical and convenient way to travel. In public transportation, bus is the most common way of public travel. However, emergency situations such as falling into the water, spontaneous combustion, and explosion may occur in the bus. After an emergency, a safety hammer needs to be used to break the windows, so that passengers can escape from the carriage in the shortest possible time. Most modern buses use airtight structures, and the window glass is toughened glass. This method not only requires the passe...

Problems solved by technology

This method not only requires the passengers to have a greater percussion force, but also has requirements on the percussion position. In an emergency, the passengers may not be able to break the window calmly and calmly, which delays the timing of escape and causes safety hazards.
