Especially in the case of a car falling into the water, the driver or passengers cannot open the door or window to escape.

[0034] To solve the technical problems existing in the related art, the present application provides a window-breaking device 10. Refer to Figures 1 - 5 , Figure 1 is a schematic structural diagram of the first embodiment in which the window-breaking device 10 provided by the present application is installed in the door 1. Figure 2 is Figure 1 the structural schematic diagram of the structure within the dashed box A in Figure 3 is a schematic structural diagram of the second embodiment in which the window-breaking device 10 provided by the present application is installed in the door 1. Figure 4 is a schematic structural diagram of an embodiment of the window-breaking device 10 provided by the present application. Figure 5It is a schematic structural diagram of an embodiment in which the window-breaking device 10 provided in the present application removes the installation sleeve 120.

[0035] The window-breaking device 10 includes an installation sleeve 120, an integrated pyrotechnic package 130, an ignition member 110, and a window-breaking cone 160; the installation sleeve 120 is formed with a first accommodation groove 121; the integrated pyrotechnic package 130 is disposed on the bottom wall of the first accommodation groove 121; the ignition member 110 is located outside the installation sleeve 120, and the ignition member 110 penetrates through the bottom wall of the installation sleeve 120; the window-breaking cone 160 is located in the first accommodation groove 121; the window-breaking cone 160 is located on one side of the integrated pyrotechnic package 130 away from the bottom wall of the first accommodation groove 121. Among them, the ignition member 110 is used to trigger the integrated pyrotechnic package 130 under the action of an external force, so as to generate gas between the integrated pyrotechnic package 130 and the window-breaking cone 160 to push the window-breaking cone 160 to move towards the notch of the first accommodation groove 121.

[0036] First, components such as the integrated pyrotechnic package 130, the ignition member 110, and the window-breaking cone 160 of the window-breaking device 10 are all disposed in the first accommodation groove 121 inside the installation sleeve 120, and the window-breaking cone 160 is located on one side of the notch of the first accommodation groove 121 and can move along the notch of the first accommodation groove 121. Specifically, the ignition member 110 can be a piezoelectric igniter, which penetrates through the bottom wall of the installation sleeve 120 and contacts the reserved lead wire of the integrated pyrotechnic package 130. When the button of the piezoelectric igniter is pressed by an external force, the piezoelectric igniter generates an electric arc to ignite the lead wire, thereby triggering the integrated pyrotechnic package 130, generating high-pressure gas in the first accommodation groove 121, and the high-pressure gas then pushes the window-breaking cone 160 to move rapidly towards the notch of the first accommodation groove 121, so that the window-breaking cone 160 impacts the glass to achieve the purpose of breaking the glass.

[0037] The above-mentioned pyrotechnic integrated package 130 is also called a fire tool, which refers to a general term for disposable components and devices that are filled with gunpowder or explosives, and produce combustion or explosion after being stimulated by external stimuli to ignite gunpowder, detonate explosives or perform mechanical work. The pyrotechnic integrated package 130 includes a primer, a primer, an ignition tube, a delay part, a detonator, a detonator tube, a fuse, a detonating cord, an explosion switch, an explosion bolt, a starter, a cutting rope, etc., which are commonly used to ignite gunpowder and detonate explosives. It can also be used as a small drive device to quickly open valves, release safety, and separate rocket stages. It should be noted that the amount of gunpowder in the pyrotechnic integrated package 130 does not need to be too much, so that the window breaking cone head 160 can break the glass. In order to facilitate better breaking of glass, the window breaking cone head 160 can be made of high-speed steel material, and the notch of the first accommodating groove 121 is placed at the fragile point of the glass. It can be understood that high-speed steel is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or sharp steel. Using it as the material for making a metal cone head and giving it a certain speed can easily break the glass. Glass usually has a fragile point, and hitting this fragile point can cause the glass to be completely broken. Therefore, placing the notch of the first accommodating groove 121 at the fragile point of the glass can allow the window-breaking cone head 160 to move along the notch of the first accommodating groove 121 to better break the glass.

[0038] The window breaking device 10 includes a stopper 170, which is arranged at the notch of the first receiving groove 121, and the stopper 170 allows being pierced by the window breaking cone 160. The stopper 170 is arranged at the notch of the first receiving groove 121, and the two ends of the stopper 170 abut against the two inner side walls of the first receiving groove 121, so as to limit the movement of the window breaking cone 160, so as to avoid the window breaking cone 160 from moving due to unexpected circumstances and causing damage to the glass when the window breaking device 10 is not triggered, such as when a car is driving on a bumpy road, the window breaking cone 160 may move due to vibration. Specifically, the stopper 170 may be a rubber strip, and the stopper 170 has a certain rigidity, so that the stopper 170 abuts against the two inner side walls of the first receiving groove 121 to generate a large friction force, and the stopper 170 is difficult to move, thereby blocking the movement of the window breaking cone 160.

[0039] The window breaking device 10 includes a first elastic member 140, which is elastically supported between the pyrotechnic integrated package 130 and the window breaking cone head 160. In some embodiments, the first elastic member 140 can be arranged in the space of the first accommodating groove 121 between the pyrotechnic integrated package 130 and the window breaking cone head 160, the diameter of the first elastic member 140 is smaller than the diameter of the first accommodating groove 121, and the first elastic member 140 is pre-set to a certain compression state. When the window breaking device 10 is triggered, the first elastic member 140 can release elastic force to assist in pushing the window breaking cone head 160 to hit the glass, making it easier to break the glass, and at the same time, the amount of gunpowder used in the pyrotechnic integrated package 130 can be relatively reduced.

[0040] The window-breaking device 10 includes a support base 150 located in the first accommodation groove 121. The support base 150 is connected to the pyrotechnic integrated package 130, and the first elastic member 140 elastically supports between the support base 150 and the window-breaking cone head 160.

[0041] The support base 150 includes a partition portion 151 and a support portion 152. The support portion 152 is used to support one end of the first elastic member 140. The partition portion 151 is located between the support portion 152 and the pyrotechnic integrated package 130 and is used to separate the pyrotechnic integrated package 130. It can be understood that since the pyrotechnic integrated package 130 is an inflammable and explosive item, the partition portion 151 helps to reduce the probability of the pyrotechnic integrated package 130 being accidentally triggered (such as being squeezed or collided). When the pyrotechnic integrated package 130 is triggered by the ignition member 110 under an external force, in addition to the high-pressure gas generated in the first accommodation groove 121 applying a thrust to the window-breaking cone head 160, a thrust can also be applied to the first elastic member 140 through the support base 150, and the first elastic member then applies a thrust to the window-breaking cone head 160 to assist in breaking the glass.

[0042] See Figure 6 , Figure 6 is Figure 2 the schematic cross-sectional structure diagram of the window-breaking device 10 shown.

[0043] The window-breaking cone head 160 includes a pushing body 161, a cone head body 162, and a second elastic member 163. The second elastic member 163 elastically supports between the pushing body 161 and the cone head body 162. Specifically, the second elastic member 163 can be a spring and is used to assist in pushing the cone head body 162 to break the window. When the pyrotechnic integrated package 130 is triggered, the pushing body 161 can apply a thrust to the cone head body 162, and at the same time, the second elastic member 163 can also apply a thrust to the cone head body 162 to assist in breaking the window. The pushing body 161 can be made of engineering plastic, which is an excellent material. Engineering plastics have excellent comprehensive properties. They have high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in relatively harsh chemical and physical environments for a long time, can replace metals as engineering structural materials, and are known for their light weight characteristics. Their density usually remains in the range of 0.9 to 2.3 grams per cubic centimeter (much lower than the density of steel), so the weight of the window-breaking device 10 can be reduced.

[0044] The driving body 161 is provided with a second accommodating groove 164, and the second elastic member 163 is located in the second accommodating groove 164. The second elastic member 163 is elastically supported between the conical head body 162 and the bottom wall of the second accommodating groove 164. Specifically, the second elastic member 163 can be a spring, which is pre-set in a certain compressed state and presses against the bottom wall of the second accommodating groove 164 and the conical head body 162. When the pyrotechnic integrated package 130 is triggered, the second elastic member 163 can release elastic force to push the conical head body 162 and assist the conical head body 162 to break the window.

[0045] A puncturing member 165 is provided on one side of the driving body 161 facing the limiting member 170. The puncturing member 165 extends towards the direction where the limiting member 170 is located, and the puncturing member 165 is used to puncture the limiting member 170. By providing the puncturing member 165 on the driving body 161, when the pyrotechnic integrated package 130 is triggered, the puncturing member 165 moves towards the limiting member 170 along with the driving body 161. At the same time, the limiting member 170 is squeezed and bent, and the puncturing member 165 can cut the limiting member 170 so that the movement of the window-breaking conical head 160 is no longer restricted, and the second elastic member 163 can also release elastic force to apply a thrust to the conical head body 162.

[0046] In the state where the ignition member 110 does not trigger the pyrotechnic integrated package 130, the limiting member 170 is in contact with the conical head body 162. In the state where the ignition member 110 triggers the pyrotechnic integrated package 130, the limiting member 170 compresses the second elastic member 163 through the conical head body 162. When no external force is applied to the ignition member 110 to trigger the pyrotechnic integrated package 130, since the limiting member 170 is in contact with the conical head body 162 and both ends are abutted against the two inner side walls of the first accommodating groove 121, the conical head body 162, the driving body 161, and the entire window-breaking conical head 160 are blocked by the limiting member 170 and cannot move. When the pyrotechnic integrated package 130 is triggered, the driving body 161 will receive a thrust moving towards the limiting member 170, and the second elastic member 163 located in the second accommodating groove 164 will also be further compressed. The limiting member 170 is squeezed and bent by the driving body 161 and the conical head body 162. When the puncturing member 165 located on the driving body 161 contacts the limiting member 170 and cuts it, the movement of the window-breaking conical head 160 is no longer restricted, and the elastic force of the second elastic member 163 is also released. Then, the window-breaking conical head 160 moves along the notch direction of the first accommodating groove 121 to impact the glass.

[0047] In summary, a window-breaking device 10 provided by the present application can trigger the pyrotechnic integrated package 130 by externally pressing the ignition member 110, so as to generate high-pressure gas in the space of the first accommodation groove 121 between the window-breaking cone head 160 and the pyrotechnic integrated package 130. The high-pressure gas pushes the window-breaking cone head 160 to move at high speed towards the notch of the first accommodation groove 121 to impact the window 30 glass. At the same time, the first elastic member 140 provided between the support base 150 and the window-breaking cone head 160 can also assist in pushing the window-breaking cone head 160 to impact the vehicle glass. The second elastic member 163 located in the second accommodation groove 164 of the pushing main body 161 can assist in pushing the cone head main body 162, so as to achieve the purpose of emergency window-breaking in case of emergencies such as fire or falling into water in the vehicle.

[0048] See again Figure 1 、 Figure 2 and Figure 3 , Figure 1 is a schematic structural diagram of the first embodiment of the window-breaking device 10 provided by the present application installed in the vehicle door 1. Figure 2 is Figure 1 the structural schematic diagram within the dashed box A in Figure 3 is a schematic structural diagram of the second embodiment of the window-breaking device 10 provided by the present application installed in the vehicle door 1.

[0049] The present application also provides a vehicle door 1, which includes a window 30, a vehicle door 1 main body, and the above-mentioned window-breaking device 10. The vehicle door 1 main body is provided with an installation groove 210 for installing the window-breaking device 10. The ignition member 110 of the window-breaking device 10 is exposed at the notch of the installation groove 210. The window-breaking device 10 is used to break the window 30. The window-breaking device 10 is installed in the installation groove 210 on the vehicle door 1. The window-breaking cone head 160 is located on the side of the installation groove 210 close to the glass, and the ignition member 110 is located at the notch of the installation groove 210. The notch of the installation groove 210 is close to the vehicle interior side. Therefore, in case of emergencies such as fire and falling into water, the user can press the ignition member 110 to activate the window-breaking device 10 to achieve the purpose of emergency window-breaking.

[0050] The main body of the vehicle door 1 includes a switch cover 220. The switch cover 220 is connected to the main body of the vehicle door 1 and can move relative to the main body of the vehicle door 1 to block or expose the notch of the installation groove 210. In some embodiments, the switch cover 220 can be provided at the notch of the installation groove 210. When the window-breaking device 10 is not activated, the switch cover 220 covers the notch of the installation groove 210 to prevent the window-breaking device 10 from being accidentally triggered due to accidental situations such as the ignition element 110 being collided or squeezed; when it is necessary to activate the window-breaking device 10, the switch cover 220 can be moved away to expose the ignition element 110 at the notch of the installation groove 210. Specifically, the switch cover 220 can be rotatably connected or slidably connected to the vehicle door 1, so that the switch cover 220 rotates or slides relative to the vehicle door 1 to expose or cover the notch of the installation groove 210. Of course, the installation method of the switch cover 220 can also adopt other forms, which are not limited here.
