[0033] When the vehicle is in an emergency situation, the people in the vehicle need to escape as soon as possible. If the door cannot be easily opened, the window becomes the only way for the people to escape at this time. But most of the vehicles on the market use double-layer laminated windows, and the double-layer laminated windows have very strong resistance to the outside and are not easy to be damaged. If the window is forcibly broken, the people in the vehicle may be injured by the flying window glass debris. Therefore, it is difficult to break the double-layer laminated window, and ordinary window breaking tools cannot safely break the window in a short time, which cannot meet the needs of emergency escape or rescue. Based on this, the present application provides a window breaking device for a vehicle for safely and timely breaking the window.

[0034] Figure 1 A structure schematic diagram of a window breaking device provided in the embodiments of the present application, the window breaking device includes a heat conducting element 11, a control module including a first power supply, a window breaking assembly 13, the window 12 of the vehicle is a double-layer laminated glass, including a first glass and a second glass bonded by laminated adhesive, the heat conducting element 11 is connected with the laminated adhesive and the first power supply. The control module is arranged on the vehicle, for example, can be arranged below the main driver's seat of the vehicle, below the co-driver's seat of the vehicle, etc. After the control module receives the failure signal, the first power supply transmits current to the heat conducting element 11, and the heat conducting element 11 heats the laminated adhesive according to the current transmitted by the first power supply to melt the laminated adhesive. The control module can also send a trigger signal to the window breaking assembly 13, and the window breaking assembly 13 breaks the window 12 according to the trigger signal.

[0035] The control module can include a control unit, and a first power supply in the control unit is configured to deliver electric current to the heat-conducting element 11. The control unit can also send a trigger signal to the window breaking assembly 13. The control module can also include two control units. A first power supply in a first control unit 16 is configured to deliver electric current to the heat-conducting element 11. The first control unit 16 is connected to the heat-conducting element 11 through a first wire harness 14. The first control unit 16 can be a heater, and the working voltage can be set to 220V, and the power can be set to 500W-1500W. A second control unit 17 is configured to send a trigger signal to the window breaking assembly 13. The second control unit 17 is connected to the window breaking assembly through a second wire harness 15.

[0036] Specifically, when the vehicle is in a failure state, such as falling into water, rolling over, or colliding, the air bag module (ABM) of the vehicle sends a failure signal to the control module. The control module receives the failure signal, and the first power supply delivers electric current to the heat-conducting element 11. The heat-conducting element 11 converts the electric energy into heat energy according to the electric current delivered by the first power supply, heats the interlayer, melts the interlayer, and causes the first glass and the second glass to partially separate. After the heat-conducting element 11 melts the interlayer, the control module can send a trigger signal to the window breaking assembly 13 after a preset time interval. The window breaking assembly 13 breaks the window according to the trigger signal.

[0037] The preset time interval can be set according to actual conditions, for example, 1 minute, 2 minutes, 3 minutes, etc.

[0038] By melting the interlayer in the double-layer interlayer glass, the part of the double-layer interlayer glass where the interlayer is melted can be quickly converted into ordinary double-layer glass when the vehicle is in an extreme working condition and the door cannot be opened, so that the adhesion and strength of the interlayer are greatly reduced, thereby reducing the resistance and impact resistance of the double-layer interlayer glass, and the double-layer interlayer glass is more easily broken, and a relatively small force can be used to break the window. After the interlayer is melted, the window breaking assembly is used to achieve automatic window breaking, and a small force is used to break the window as soon as possible, which helps the passengers inside the vehicle to escape quickly and safely or helps the rescuers outside the vehicle to rescue quickly, reduces the possibility of injury to the passengers inside the vehicle by the flying glass fragments, and improves the safety of window breaking.

[0039] In order to better and more completely break the window and avoid glass fragments splashing into the passengers inside the vehicle, in one embodiment, the control module includes a timer, and the control module triggers the window breaking assembly to break the window by monitoring the time information in the timer.

[0040] The timer includes but is not limited to one or more of an RC (Resistance-Capacitance) circuit timer, a crystal oscillator, a pulse generator-based timer, and a timer integrated circuit.

[0041] When the first power supply starts to deliver current to the heat-conducting element 11, the timer starts timing, and when the timing reaches the preset time length, the heat-conducting element 11 melts the interlayer. At this time, the control module triggers the window breaking assembly 13 to break the window, which can greatly reduce the viscosity and strength of the interlayer, thereby reducing the resistance and impact resistance of the double interlayer glass, and the double interlayer glass is more easily broken, which can better and more completely break the vehicle window, avoiding the glass debris splashing into the vehicle occupants.

[0042] In order to improve the heating speed of the interlayer, in an embodiment, the heat-conducting element 11 is arranged between the first glass and the second glass and in contact with the interlayer.

[0043] Arranging the heat-conducting element 11 between the first glass and the second glass and in contact with the interlayer can heat the interlayer faster to reach the melting point of the interlayer, thereby breaking the vehicle window as soon as possible to enable the vehicle occupants to escape as soon as possible or to be rescued as soon as possible.

[0044] In an embodiment, the heat-conducting element 11 includes a heat-conducting resistor.

[0045] The first power supply in the control module delivers current to the heat-conducting resistor, and the heat-conducting resistor can convert electrical energy into heat energy according to the current delivered by the first power supply to heat the interlayer.

[0046] In order to provide stable heating effect, in an embodiment, the heat-conducting resistor is a metal wire.

[0047] The metal wire can quickly convert electrical energy into heat energy to provide efficient heating effect, and the heat generated by heating can be uniformly distributed to avoid local overheating or overcooling, thereby providing stable heating effect to improve overall heating efficiency and reduce energy waste.

[0048] In order to break the vehicle window faster and more safely, in an embodiment, the heat-conducting element 11 is spaced apart from the edge of the vehicle window 12 by a preset distance and surrounds the edge of the vehicle window 12.

[0049] The preset distance is set according to actual conditions, for example, it can be 3 cm, 5 cm, etc.

[0050] The heat-conducting element 11 surrounds the edge of the vehicle window 12 and is spaced apart from the edge of the vehicle window 12 by a preset distance, which can heat the interlayer around the edge of the vehicle window 12. When the interlayer melts, the window breaking assembly 13 can quickly break the entire glass along the edge of the vehicle window 12, thereby reducing the possibility of the vehicle occupants being injured by the splashed vehicle window glass debris and improving the safety of breaking the window.

[0051] In order to completely break the vehicle window and avoid injury to the vehicle occupants by glass debris, in an embodiment, the heat-conducting element 11 surrounds the edge of the vehicle window 12 and is connected at the beginning and the end to form a closed shape.

[0052] Among them, the closed shape can be the shape of the window edge, or an oval, etc.

[0053] If the heat-conducting element 11 does not form a closed shape and is set at multiple points, when the window-breaking component 13 breaks the window, cobwebs will be formed at multiple points, and the whole piece of glass cannot be directly broken. Moreover, the glass fragments generated when breaking the window are very likely to hurt the vehicle occupants. In the embodiment of the present application, the heat-conducting element 11 is connected end to end around the edge of the window 12 to form a closed shape, which can heat the interlayer glue around the edge of the window 12. When the interlayer glue melts, the window-breaking component 13 can quickly break the whole piece of glass along the edge of the window 12. Compared with breaking the window at a single point and then gradually expanding the window-breaking range, quickly breaking the whole piece of glass along the edge of the window 12 in the embodiment of the present application can improve the window-breaking speed and the safety of window-breaking, and avoid the splashing of glass fragments.

[0054] In order to heat the interlayer glue faster and in a larger range and improve the heating efficiency, in one embodiment, the heat-conducting element 11 surrounds the edge of the window 12 at least two times and is arranged in a nested circular pattern.

[0055] The heat-conducting element 11 surrounds the edge of the window 12 at least two times and is arranged in a nested circular pattern, forming a shape like a Chinese character 'hui' or a concentric circle, which can heat the interlayer glue faster and can heat a larger range of interlayer glue. On the basis of heating the interlayer glue as soon as possible, it reduces the force required to break the window 12, enabling the vehicle occupants to escape quickly and safely or enabling rapid rescue outside the vehicle.

[0056] In order to improve the window-breaking efficiency, in one embodiment, the heat-conducting element 11 at least includes one of the following: nickel-chromium wire, nickel wire.

[0057] The material of the interlayer glue can be PVB (Polyvinyl Butyral). The melting point of the PVB material is 65°C to 185°C. The nickel-chromium wire and nickel wire have high thermal efficiency and can quickly generate heat when powered on, efficiently converting electrical energy into heat energy. The temperature of the nickel-chromium wire and nickel wire can reach 200°C within 1 minute when powered on, reaching the melting point of the interlayer glue, thereby greatly reducing the strength of the interlayer glue. The heating speed of the nickel-chromium wire and nickel wire is fast, thus improving the window-breaking efficiency and the speed of vehicle occupants' escape.

[0058] When the interlayer glue melts, the window-breaking component 13 can be used to achieve automatic window-breaking and improve the window-breaking efficiency. In one embodiment, the window-breaking component 13 includes a window-breaking trigger and a window-breaking actuator, and the window-breaking trigger is used to trigger the window-breaking actuator to break the window according to the trigger signal of the control module.

[0059] In an emergency, the broken window trigger automatically triggers the broken window executor to break the window after receiving the trigger signal, without the need for manual operation, and can work automatically in the case that personnel cannot manually operate or start the broken window component, thereby improving the rescue efficiency of rescue personnel, saving valuable escape time, and improving the safety of breaking the window.

[0060] In one embodiment, as shown in Figure 2 , the broken window trigger includes a movable piece 21 and a second power supply;

[0061] The broken window executor includes a spring 26 and a conical hammer 27, one end of the spring 26 is connected to the movable piece 21, and the other end of the spring 26 is connected to the end of the conical hammer 27 opposite the sharp end;

[0062] Wherein, after the broken window trigger receives the trigger signal, the second power supply is started, so that the broken window trigger drives the spring 26 to change from the compressed state to the stretched state, to drive the sharp end of the conical hammer 27 to break the window 12.

[0063] As shown in Figure 2 , the movable piece 21 and the fixed piece 25 are connected by a connecting rod 24, and the fixed piece 25 is connected to the rear end of the spring 26, and the fixed piece 25 is used to connect the spring 26 and the movable piece 21, so that the movable piece 21 can drive the spring 26 to move through the fixed piece 25. When the broken window trigger does not receive the trigger signal, the first contact 22 and the second contact 23 in the movable piece 21 are separated, the spring 26 is clamped in the buckle 28, and is in the compressed state, and the conical hammer 27 cannot contact the window 12. As shown in Figure 3 , when the broken window trigger receives the trigger signal, the second power supply is started, the first contact 22 and the second contact 23 are attracted, the movable piece 21 drives the fixed piece 25 to move through the connecting rod 24, the fixed piece 25 drives the spring 26 to pop out of the buckle 28, and the spring 26 changes from the compressed state to the stretched state, at this time the sharp end of the conical hammer 27 pops out and breaks the window 12.

[0064] Wherein, the broken window component 13 can be arranged at multiple points of the window, for example, as shown in Figure 1 , ①-⑥ can be arranged along the edge of the window, a total of 6 broken window components 13, or more broken window components 13 can be arranged.

[0065] The broken window principle of the broken window device of the vehicle will be further explained as follows: Figures 1-3

[0066] ​The control module is arranged under the seat of the vehicle. When the vehicle fails, the ABM of the vehicle sends a failure signal to the control module. The first power supply delivers electric current to the heat-conducting element 11. The temperature of the heat-conducting element 11 is controlled by the control module. The heat-conducting element 11 can be a nichrome wire or a nickel wire. The nichrome wire or the nickel wire is arranged between the first glass and the second glass and in contact with the interlayer. The nichrome wire or the nickel wire surrounds the edge of the vehicle window 12 and forms a closed shape. The nichrome wire or the nickel wire converts electric energy into heat energy according to the electric current delivered by the first power supply. The temperature reaches 200℃ within 1 minute. The interlayer around the edge of the vehicle window 12 is heated to melt the interlayer, so that the interlayer strength of the first glass and the second glass is greatly reduced, and the first glass and the second glass are partially separated. After the heat-conducting element 11 melts the interlayer, for example, after 180 seconds, the control module sends a trigger signal to the window breaking assembly 13 again. The window breaking trigger in the window breaking assembly 13 starts the second power supply. The first contact 22 and the second contact 23 are attracted. The movable part 21 in the window breaking trigger drives the fixed part 25 to move through the connecting rod 24. The fixed part 25 drives the spring 26 to pop out of the buckle 28. At this time, the tip of the conical hammer 27 pops out and quickly breaks the whole glass along the edge of the vehicle window 12.
