Description

Technical Field

[0001] This utility model relates to the field of bus safety equipment technology, specifically to an electric automatic glass-breaking device. Background Technology

[0002] With the continuous development of society, buses have become an indispensable public transportation tool. As bus companies attach increasing importance to the safety of buses, methods of breaking bus windows have been widely developed as an important emergency escape route.

[0003] There are two common types of glass breakers on the market: one is a mechanical glass breaker hammer, which is attached to the window frame of a bus and can be inserted and removed. It requires manual glass breaking and is less efficient than an automatic glass breaker. The other is a pneumatic glass breaker, which is an automatic glass breaker, but this type of glass breaker has the risk of accidental explosion due to vehicle bumps. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric automatic glass breaking device, which aims to solve the problems of low glass breaking efficiency and safety hazards in the existing technology.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: When a glass breaking operation is required, pressing the switch triggers the device, which drives the motor rocker arm to rotate. When the motor rocker arm pushes the hammer to the highest point, the torsion spring reaches its maximum energy storage. When the motor rocker arm continues to rotate and slides past the hammer, the torsion spring releases its energy storage, causing the hammer to hit the striking pin and strike the car window glass. This device can solve the problem of low glass breaking efficiency of mechanical glass breakers, and is also safer than pneumatic automatic glass breakers.

[0007] Furthermore, the striking assembly also includes a striking hammer bracket. The striking hammer bracket is connected to the inside of the housing near the side of the motor rocker arm. One end of the striking hammer bracket is rotatably connected to a pin. The pin is fixedly connected to the striking hammer. The striking hammer extends from the pin towards the motor rocker arm. The torsion spring is fixedly connected to the striking hammer bracket. One end of the torsion spring abuts against one side of the striking hammer.

[0008] Furthermore, the firing pin assembly includes a firing pin bracket, on which a firing pin is slidably connected. The firing pin is located on the side of the striking hammer facing away from the torsion spring, and the striking hammer abuts against the end of the firing pin facing away from the opening.

[0009] Furthermore, a limiting plate is connected to the firing pin, the diameter of which is larger than the diameter of the opening, and a tower spring is fitted onto the firing pin, the tower spring being located between the limiting plate and the inner wall of the housing.

[0010] Furthermore, the end of the striking hammer facing away from the pin is rotatably connected to a miniature bearing, and the end of the motor rocker arm facing away from the motor has an arc surface.

[0011] Furthermore, the end of the firing pin facing away from the striking hammer is conical.

A motor bracket 3 is connected inside the housing 1 and is fixedly connected to one side of the inner wall of the housing 1. The motor bracket 3 is connected to a motor 2, and the switch is electrically connected to the motor 2. A power source is connected inside the housing, and the power source is electrically connected to the motor 2. A through hole is formed in the motor bracket 3, and the output end of the motor 2 is rotatably connected to a motor rocker arm 4 through the through hole. The rotation range of the motor rocker arm 4 is... The motor rocker arm 4 has a 360-degree radius. The end of the motor rocker arm 4 furthest from the output end of the motor 2 is an arc surface to prevent jamming between the motor rocker arm 4 and the striking hammer 13. A striking assembly is installed inside the housing 1, including a striking hammer bracket 11 and a striking hammer 13. The striking hammer bracket 11 is connected to the side of the housing 1 closest to the motor rocker arm 4. Two fixed seats 16 are connected to the end of the striking hammer bracket 11 furthest from the motor rocker arm 4. The two fixed seats 16 are connected to opposite sides of the striking hammer bracket 11, and a pin 15 is rotatably connected between the fixed seats 16.

The limiting plate 25 prevents the striking pin 23 from falling off. A tower spring 21 is fitted onto the striking pin 23, located between the limiting plate 25 and the inner wall of the housing 1. A groove is provided at the end of the striking hammer bracket 11 near the striking pin 23, adapting to the striking pin 23 to prevent the striking pin 23 from shifting during sliding.Further improve the stability of the automatic glass-breaking device.

[0025] When it is necessary to break the car window, open the protective cover 31, press the switch 3 to trigger the device, and the motor 2 drives the motor rocker arm 4 to rotate. When the motor rocker arm 4 pushes the hammer 13 to the highest point, the torsion spring 14 reaches its maximum energy storage. When the motor rocker arm 4 continues to rotate and slides past the miniature bearing 12, the torsion spring 14 releases its energy storage, causing the hammer 13 to hit the striker 23 and break the car window glass. At the same time as the striker 23 hits the glass, the tower spring 21 stores energy and then releases it, causing the striker 23 to return to its original position. This device can solve the problem of low efficiency of mechanical glass breakers. At the same time, the electric automatic glass breaker is safer than the pneumatic automatic glass breaker, and there is no safety hazard of accidental activation of the glass breaker due to car bumps.
