Description

Technical Field

[0001] This utility model belongs to the field of window breaker technology, and in particular relates to an electric window breaker device. Background Technology

[0002] A window breaker is an emergency escape tool used to break windows and escape in an emergency. Its principle is based on the fact that when tempered glass reaches its stress limit at a certain point, the entire piece of tempered glass will shatter. The basic principle of a window breaker is to compress and store energy in a spring connected to a breaker pin, and then release it, giving the breaker pin a tremendous impact force to strike the tempered glass and cause it to break.

[0003] Traditional window breakers mainly rely on mechanical impact methods, such as pressing a spring or manually striking with a hammer. However, they have the following drawbacks: in emergency situations, occupants may be unable to effectively use manual window breakers due to panic or injury, leading to delays in escape; window breakers are independent mechanical structures and cannot be activated autonomously. In the event of fire, drowning, or violent impact, the window breaker cannot break the glass on its own when the driver or passengers are temporarily incapacitated.

[0004] Therefore, there is a need for an electrically driven car window breaking escape device that can automatically and quickly shatter car windows in dangerous situations such as vehicle submersion, fire, or collision, providing an escape route for occupants. Existing window breakers have a shattering needle that extends along the length of the glass and is set perpendicular to the glass, requiring a large space perpendicular to the glass. Simply changing the drive of the window breaker to electric drive cannot meet the thickness installation requirements at the car window. Therefore, it is necessary to provide an electric window breaking device that can achieve electric drive while meeting the vehicle installation space requirements at the window.

A spring and a hammer are sequentially arranged inside the first housing from the first end. A fixing groove is provided on the outer wall of the hammer. A fixing hole is provided through the first housing. When the fixing groove corresponds to the fixing hole, the hammer compresses the spring. A retaining ball is placed in the fixing hole. A fixing sleeve is provided outside the first housing, sealing the fixing hole to prevent the retaining ball from disengaging, thus forcing the retaining ball to engage with the window through the fixing hole. The fixing groove fixes the hammer; the second housing is an L-shaped hollow tubular structure with a third end and a fourth end that are perpendicular to each other. The third end is fixedly connected to the second end and the interior communicates to form a chamber.
