Traditional window-breaking devices mainly rely on mechanical hitting methods, such as spring impact or manual hammering, but they have the following defects: (1) In an emergency, the occupants may be unable to effectively use the manual window-breaking tool due to panic or injury, resulting in a delay in escape; (2) Most of the known window-breaking devices are installed in the upper part of the glass, which is not aesthetically pleasing; (3) The window-breaking device is an independent mechanical structure and cannot be activated autonomously. When there is combustion, drowning or a violent impact, and the driver or passenger temporarily loses the ability to move, the window-breaking device cannot break the glass autonomously; Based on this, we have made technical improvements to the existing window-breaking devices to meet the usage requirements.

[0011] The technical problem to be solved by the present invention can also be achieved by the following technical solution.

When the airbag explodes due to high temperature caused by fire in the car, water ingress into the car and violent collision, the discharge circuit is turned on to ignite the chemical energy bag and prompt the glass-breaking head to quickly hit the glass, thereby achieving glass-breaking operation. This completely solves the fatal defect of traditional glass breakers that rely on manual operation, ensures that occupants can still get a chance to escape when they lose the ability to move, and greatly improves the rescue success rate of vehicle accidents.

[0017] The following further describes the specific technical solutions of the present invention with reference to the accompanying drawings, so as to facilitate those skilled in the art to further understand the present invention without restricting its rights.
[0018] Example 1. Refer to Figures 1-4 , a fully automatic vehicle window-breaking escape device, including a window-breaking device body 1, which is formed into a substantially cylindrical structure and has; A glass clamping port 2, which is opened between the two ends of the window-breaking device body 1 and is configured to clamp the bottom of the glass; A clamping member 3, which is installed on one end of the window-breaking device body 1 and forms an adjustable gap for glass clamping with the end face of the glass clamping port 2. The clamping member 3 is a fastener threadedly connected to the inner wall or outer wall of the window-breaking device body 1. Correspondingly, a thread for its cooperation may be provided on the inner peripheral surface or outer peripheral surface of the end of the window-breaking device body 1. The fastener may be a bolt or a nut. During its movement towards the glass clamping port 2, it can form a clamping force for clamping the glass with the glass clamping port 2, so as to keep the window-breaking device body 1 fixed on the bottom of the glass; In addition, when the clamping member 3 is built into the end of the window-breaking device body 1, the end of the window-breaking device body 1 has a through hole for the clamping member 3 to enter. If the clamping member 3 is sleeved on the outer wall of the window-breaking device body 1, the end of the window-breaking device body 1 is arranged in a closed shape; A window-breaking power mechanism, which is installed on the other end of the window-breaking device body 1 away from the clamping member 3; A window-breaking head 4, which is formed into a substantially conical metal structure. Its material can be tungsten steel and can be selected according to actual use requirements. It is installed in the window-breaking device body 1 and is located between the glass clamping port 2 and the window-breaking power mechanism. In order to keep the window-breaking head 4 moving smoothly, a piston 5 that can slide along the inner wall of the window-breaking device body 1 is fixedly provided at the end of the window-breaking head 4 away from the glass clamping port 2; A triggering mechanism, which is configured to selectively trigger the window-breaking head power mechanism to provide power for the window-breaking head 4 to move towards the glass clamping port 2.
[0019] Example 2. For the fully automatic vehicle window-breaking escape device described in Example 1, the window-breaking head power mechanism includes; A discharge circuit, which has a power source and an arc output terminal 6 for generating an ignition arc. The discharge circuit is connected in series with a power source 7. The positive and negative poles of the power source 7 are connected by a power cord to a pair of discharge electrodes, which serve as the following arc output terminal 6, and the discharge electrodes extend into the following chemical energy capsule 8, thereby constituting a discharge circuit that can ignite the chemical energy capsule 8; A chemical energy release unit, which is arranged within the range of action of the ignition arc and is configured to generate chemical energy for pushing the window-breaking head 4 to move after being ignited by the ignition arc. The chemical energy release unit includes; A sealing plate 9, which is arranged at the end of the glass breaker body 1 and can be specifically connected by threads, and is formed into a substantially plate-like structure; A chemical energy capsule 8, which is fixed on one end face of the sealing plate 9 facing the glass clamping port 2, and is filled with an explosive combustion agent inside, and the composition of the explosive combustion agent can be configured according to the use requirements; The arc output end 6 of the discharge circuit, that is, the discharge electrode, extends into the chemical energy capsule 8.
[0020] Example 3, a vehicle glass breaker described in Example 2, wherein the triggering mechanism is a trigger switch connected in series in the discharge circuit, and the trigger switch includes a thermal switch 10 and a water-sensitive switch 11 arranged in parallel with each other; The thermal switch 10 is configured to conduct the discharge circuit after reaching the temperature threshold; The water-sensitive switch 11 is configured to conduct the discharge circuit after reaching the water level threshold.
[0021] In Example 3: (1) The model of the thermal switch 10 can be selected as a model with a temperature threshold between 120°C ± 10°C. When reaching this temperature, the thermal switch 10 closes, thereby conducting the discharge circuit. The thermal switch 10 can be placed inside the engine hood of the vehicle, and its specific placement height and position can be selected according to the height of different vehicle models. Its model can be the thermal switch 10 in the prior art; (2) The model of the water-sensitive switch 11 can be selected according to the use requirements. For example, a water immersion sensor with normally open contacts connected in series in the discharge circuit. When water enters the vehicle, since water is a conductor, at this time the water will conduct the water-sensitive switch 11, thereby causing the water-sensitive switch 11 to close, and then conducting the discharge circuit. The water-sensitive switch 11 can be installed 10 centimeters above the brake pedal inside the vehicle, or placed inside the vehicle storage box (generally, the sealing of the vehicle storage box is not very good, so when the water submerges the storage box, it will seep into the storage box and trigger the water-sensitive switch 11), and its installation height can be selected according to the use requirements.
[0022] Example 4, a vehicle glass breaker described in Example 3, wherein the arc output end 6 is a pair of discharge electrodes. The positive pole of the power supply 7 is connected to one of the discharge electrodes through a wire to form a positive pole path, and the negative pole of the power supply 7 is connected to one of the discharge electrodes through a wire to form a negative pole path. The triggering mechanism is connected in series in the positive pole path; It also includes a starting branch 12, one end of which is connected to the negative electrode loop of the vehicle's own airbag ignition circuit, and the other end of the starting branch 12 is connected to the negative electrode path and is located between the trigger mechanism and the discharge electrode. It is configured to trigger the airbag and turn on the discharge circuit when the vehicle-mounted airbag ignition circuit is turned on. Because the layout of the vehicle-mounted airbag ignition circuit of different models of cars is different, and it is a prior art, it can be selected according to usage requirements, and its specific composition will not be repeated here.
[0023] In the fourth embodiment, it should be noted that the end of the start branch 12 can be connected to the load side (negative loop, i.e., the node between the igniter and the ground) of the igniter in the vehicle airbag ignition circuit, and its connection position is not limited thereto, that is, after the vehicle airbag ignition circuit is turned on, the airbag and the discharge circuit are triggered at the same time, prompting the glass breaking head 4 to perform the window breaking operation; The power source 7 is connected in parallel with the battery of the vehicle through a power line, and is configured to be charged by the battery of the vehicle. The power source 7 can be a lithium battery with a voltage of 12V.
