Description

Window breaking escape device applied to passenger car falling into water

Technical Field

The invention relates to the technical field of public safety of vehicles, in particular to a window breaking escape device applied to the condition that a passenger car falls into water.

Background

The public transportation safety significance is great. In the face of sudden accidents of buses, particularly, the problem that the doors cannot be normally opened due to fire, dense smoke, mechanical deformation and the like is a primary task of how to ensure that passengers safely and quickly escape from the site. At present, a safety hammer with a configured foundation is taken as a main countermeasure on a bus, but the bus still has a plurality of problems in design and use, including confirmation of a correct hammering point position, a hammering direction, reasonable hammering force, a use mode and the like.

Under the circumstances such as car accident or conflagration, window glass utilizes safe hammer still to open with suitable position and dynamics easily, but in case the vehicle falls the aquatic, glass has sunk under water, it will be extremely difficult to break glass this moment, because the vehicle falls into water completely after, there is the pressure differential inside and outside the car, glass fuses as an organic whole because of the pressure differential with the water, produce huge rigidity, glass is extremely difficult to be broken, in addition because chaotic condition, people hardly find safe hammer in the short time, and oxygen in the confined space can be less and less, lead to in case the bus falls into water and just cause a large amount of casualties easily.
