Description

Technical Field

[0001] This utility model relates to the field of glass breaking technology, specifically a fully automatic car window breaking escape device. Background Technology

[0002] With the continuous development of automotive safety technology, fully automatic car window breaking escape devices, as emergency escape devices, can quickly shatter car windows in dangerous situations such as vehicles falling into water, fires, or collisions, providing an escape route for occupants. Traditional window breakers mainly rely on mechanical impact methods, such as spring impacts or manual hammering, but they have the following drawbacks:

[0003] (1) In an emergency, occupants may be unable to effectively use manual window-breaking tools due to panic or injury, resulting in a delay in escape;

[0004] (2) Most known glass breakers are installed on the upper part of the glass, which is not aesthetically pleasing;

[0005] (3) The glass breaker is an independent mechanical structure and cannot start on its own. When there is a fire, drowning or violent impact, the glass breaker cannot break the glass on its own when the driver or passenger is temporarily incapacitated.

[0006] Based on this, we have made technical improvements to existing glass breakers to meet usage requirements. Utility Model Content

[0025] The thermal switch is configured to conduct the discharge circuit after reaching a temperature threshold.

[0026] The water-sensitive switch is configured to activate the discharge circuit after reaching the water level threshold.

[0027] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the fully automatic car window breaking escape device described above, wherein the arc output end is a pair of discharge electrodes, the positive terminal of the power supply is connected to one of the discharge electrodes by a wire to form a positive electrode path, the negative terminal of the power supply is connected to one of the discharge electrodes by a wire to form a negative electrode path, and the triggering mechanism is connected in series in the positive electrode path.

[0032] (2) The triggering mechanism includes a thermal switch, a water-sensitive switch and a starting branch, which can realize a variety of triggering conditions. Under the scenarios of high temperature inside the vehicle, water entering the vehicle and violent collision causing the airbag to burst, the discharge circuit is turned on to ignite the chemical energy bag and cause the glass breaking head to hit the glass quickly, thereby achieving the glass breaking operation. This completely solves the fatal defect of traditional glass breaking devices relying on manual operation, ensuring that occupants can still have an escape opportunity when they lose the ability to move, and greatly improving the success rate of vehicle accident rescue.

[0038] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0039] Example 1, referring to Figure 1-4 A fully automatic car window breaking escape device includes a glass breaker body 1, which is formed into a generally cylindrical structure and has the following characteristics:

[0040] Glass clamping port 2, which is opened between the two ends of the glass breaker body 1, is configured to clamp the bottom of the glass.

[0041] The clamping member 3 is installed on one end of the glass breaker body 1 and forms an adjustable glass clamping gap with the end face of the glass clamping opening 2. The clamping member 3 is a fastener that is threadedly connected to the inner or outer wall of the glass breaker body 1. Correspondingly, the inner or outer circumferential surface of the end of the glass breaker body 1 can be provided with threads for use with it. The fastener can be a bolt or nut. During its movement toward the glass clamping opening 2, it can form a clamping force with the glass clamping opening 2 to clamp the glass, thereby keeping the glass breaker body 1 fixed on the bottom of the glass.

[0042] In addition, when the clamping member 3 is built into the end of the glass breaker body 1, the end of the glass breaker 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 glass breaker body 1, then the end of the glass breaker body 1 is closed.

[0043] The glass-breaking power mechanism is installed on the other end of the glass-breaking device body 1 away from the clamping member 3;

[0044] The glass-breaking head 4 is formed into a roughly conical metal structure. Its material can be tungsten steel, which can be selected according to the usage requirements. It is installed inside the glass-breaking device body 1 and located between the glass clamping port 2 and the glass-breaking power mechanism. In order to ensure that the glass-breaking head 4 can move smoothly, a piston 5 that can slide along the inner wall of the glass-breaking device body 1 is fixed on the end of the glass-breaking head 4 away from the glass clamping port 2.

[0045] The triggering mechanism is configured to selectively trigger the glass-breaking head power mechanism to provide power to move the glass-breaking head 4 toward the glass clamping opening 2.

[0046] Example 2, the fully automatic car window breaking escape device described in Example 1, wherein the power mechanism of the window breaking head includes;

[0047] The discharge circuit has a power supply and an arc output terminal 6 that generates an ignition arc. The discharge circuit is connected in series with a power supply 7. The positive and negative terminals of the power supply 7 are connected to a pair of discharge electrodes through a power supply line. The discharge electrodes serve as the arc output terminal 6 described below, and the discharge electrodes extend into the chemical energy capsule 8 described below, thereby forming a discharge circuit that can ignite the chemical energy capsule 8.

[0048] A chemical energy release unit is located within the effective range of the ignition arc and is configured to generate chemical energy that propels the glass-breaking head 4 after being ignited by the ignition arc. The chemical energy release unit includes:

[0049] The sealing plate 9 is located at the end of the glass breaker body 1 and can be threaded, forming a roughly plate-like structure.

[0050] The chemical energy capsule 8 is fixed to one end of the sealing plate 9 facing the glass clamping opening 2. It is filled with a deflagration agent, the composition of which can be configured according to the usage requirements.

[0051] The arc output terminal 6 of the discharge circuit, i.e. the discharge electrode, extends into the chemical energy capsule 8.

[0052] Example 3, a 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 connected in parallel.

[0053] The thermal switch 10 is configured to conduct the discharge circuit after reaching the temperature threshold.

[0054] The water-sensitive switch 11 is configured to conduct the discharge circuit after the water level threshold is reached.

[0055] In Example 3:

[0056] (1) The thermal switch 10 can be selected from models with a temperature threshold between 120℃±10℃. When the temperature is reached, the thermal switch 10 closes, thereby conducting the discharge circuit. The thermal switch 10 can be placed inside the engine hood of the vehicle. 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.

[0057] (2) The model of the water-sensitive switch 11 can be selected according to the usage requirements. For example, the normally open contact is connected in series in the discharge circuit of the water immersion sensor. When water enters the car, since water is a conductor, the water will conduct the water-sensitive switch 11, thereby causing the water-sensitive switch 11 to close and then conduct the discharge circuit. The water-sensitive switch 11 can be installed 10 cm above the brake pedal in the car, or placed in the car storage box (generally the sealing of the car storage box is not very good, so when the water is above the storage box, it will seep into the storage box and trigger the water-sensitive switch 11). Its installation height can be selected according to the usage requirements.

[0058] Example 4, a glass breaker described in Example 3, wherein the arc output terminal 6 is a pair of discharge electrodes, the positive terminal of the power supply 7 is connected to one of the discharge electrodes by a wire to form a positive electrode path, the negative terminal of the power supply 7 is connected to one of the discharge electrodes by a wire to form a negative electrode path, and the triggering mechanism is connected in series in the positive electrode path.

[0059] It also includes a starting branch 12. One end of the starting branch 12 is connected to the negative circuit of the vehicle's own airbag ignition circuit, and the other end of the starting branch 12 is connected to the negative circuit and located between the triggering mechanism and the discharge electrode. It is configured to trigger the airbag and conduct the discharge circuit when the vehicle airbag ignition circuit is turned on. Since the layout of the vehicle airbag ignition circuit of different models is different and it is existing technology, it can be selected according to the usage requirements. Its specific structure will not be described here.

[0060] In Example 4, it should be noted that the end of the starting branch 12 can be connected to the load side (negative circuit, i.e. the node between the igniter and ground) of the ignition device in the vehicle airbag ignition circuit. Its connection position is not limited to this. That is to say, after the vehicle airbag ignition circuit is turned on, the airbag and the discharge circuit are triggered at the same time, causing the glass breaking head 4 to perform window breaking operation.

[0061] The power source 7 is connected in parallel to the vehicle's battery via a power cord, and is configured to be charged by the vehicle's own battery. The power source 7 can be a 12V lithium battery.
