Description

Fixed window breaker

Technical Field

The invention relates to the technical field of vehicle safety, in particular to a fixed window breaker.

Background

In order to enable the existing buses and buses to run on highways more quickly, a whole piece of toughened window glass is mostly adopted. During the long-distance running process of the vehicle, some accidents inevitably happen. Under the condition that the vehicle burns in the carriage or the vehicle overturns, passengers in the carriage often need to save themselves in the first time, break window glass and open an outward escape passage. In order to facilitate escape in emergency, the existing passenger car is provided with a window breaker, and the window breaker can be used for breaking window glass to realize escape in emergency. When an accident occurs, a passenger firstly needs to find the window breaker and can break the automobile window by a correct window breaking method, under the condition of nervousness and confusion, the passenger not only needs to quickly take the window breaker but also needs to be correctly used, certain difficulty is caused, once the window breaker falls off in knocking, the consequence is not reasonable, precious time is delayed, and the passenger even possibly loses the escape opportunity. The window breaker of the existing passenger car has the defect of insufficient operation convenience. In order to overcome the defects of the conventional window breaking device, various window breaking device schemes are provided for numerous patents. For example, the authorized bulletin numbers CN105999572A "a multifunctional automobile window breaker", CN206566367U "a window breaker and a window breaker using the window breaker" and the like, these window breakers provide beneficial tools for emergency escape when a bus has an accident, but they have a common defect that a window breaker needs to be found when a danger comes, and because the provided window breaker is small and exquisite, the hardness of the ejection spring is strong, the window breaker is difficult to be used normally by old, weak and children, even for adults, if the strength is insufficient or the using method is not correct, the toughened glass is difficult to be broken to realize escape and self rescue; particularly, when the vehicle is inclined and overturned by ninety degrees, the passenger cannot take the window breaker easily, and even if the window breaker is taken, the passenger cannot knock the toughened glass arranged on the top by the window breaker. The prior art has portable window breaker, and this window breaker is small and exquisite portable, but need to trigger this device and break the window, must hold this device and exert pressure more than 10 kilograms to toughened glass's direction and can reach the purpose of trigger cone head broken window, and this is still not suitable for children and old and weak people, or when the door window is above. Before, this research and development team design has the broken window ware of fixing on toughened glass, but this type of broken window ware need reserve the hole of fixed broken window ware on toughened glass, can't install on the current door window that does not preset the fixed orifices.
