Technical Field

[0001] This application belongs to the field of vehicle escape technology, and particularly relates to an escape device, a sunroof, and a vehicle. Background Technology

[0002] Currently, the most common type of escape device on the market is the manual knocking type. This type of device requires manual force to knock on the edge of the glass. Manual escape devices are relatively large, which affects the overall appearance of the vehicle interior. In addition, it usually takes multiple knocks to successfully break the window, and the stability and reliability are insufficient, which will delay the precious escape time of the people inside the vehicle. Summary of the Invention

[0013] In one possible implementation, the electric generator includes a second elastic element that, in the second state, is elastically compressed between the second portion and the piezoelectric element; when the first portion strikes the piezoelectric element, the second elastic element provides an elastic force to the first portion and the top cover, causing both the first portion and the top cover to move away from the piezoelectric element and extruding the second portion out of the notch.

[0014] In one possible implementation, the inner wall forming the through hole includes a first inclined wall. When switching from the first state to the second state, the top cover moves toward the piezoelectric element, and the first inclined wall is used to squeeze the second portion so that the second portion falls from the first opening into the notch.

[0015] In one possible implementation, the inner wall forming the through hole includes a second inclined wall that is close to the piezoelectric element relative to the first inclined wall; when switching from the first state to the second state, the top cover moves toward the piezoelectric element, and the second inclined wall is used to press the second portion so that the second portion moves from the notch to the first opening.

[0016] In one possible implementation, the escape device includes a second housing connected to the first housing, the second housing having a second receiving cavity; the gas generator is received and fixed within the second receiving cavity; the escape device further includes a wire, one end of which is located within the first receiving cavity and electrically connected to the piezoelectric element, and the other end of which is located within the second receiving cavity and electrically connected to the gas generator.

[0019] In one possible implementation, the second receiving cavity penetrates the second housing, and the reaction cavity penetrates the bushing; the gas generator includes a lower cover and a sealing ring, the lower cover being disposed on one end of the second housing opposite to the first annular step, and the sealing ring being disposed between the bushing opposite to the second annular step and the lower cover, the sealing ring being used to seal the reaction cavity and the second receiving cavity.

[0020] In one possible implementation, the combustible material burns and forms gas in the reaction chamber; a nozzle is provided on the bushing, the nozzle connecting the reaction chamber and the outside of the second housing, the nozzle being used to collect the gas formed after the combustible material burns, so as to release the gas formed after the combustible material burns from the outside of the second housing.

Detailed Implementation

[0044] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] With the development of the automotive industry and consumer demand, sunroofs have gradually become standard equipment on most car models. Sunroofs not only provide a wider view and ventilation, but they also serve as an important escape route in the event of an accident, especially after a vehicle has fallen into water and the doors cannot be opened; opening the sunroof can significantly increase the chances of passenger escape.

[0047] Please see Figure 1 , Figure 1 This is a partial structural diagram of a vehicle provided in one embodiment of this application.

[0048] Based on this, this application provides a vehicle 1000, which includes a sunroof 101 and a roof 103, with the sunroof 101 disposed on the roof 103 of the vehicle 1000. The sunroof 101 provides a wider field of vision from the roof of the vehicle 1000 and facilitates ventilation and air exchange inside the vehicle 1000. Simultaneously, the sunroof 101 can be designed as an escape route for the vehicle 1000, increasing the chances of passenger escape in the event of an accident.

[0049] However, most sunroofs on the market do not have emergency escape devices. If a vehicle falls into water and loses power, there is a risk that the sunroof cannot be opened in time, which will reduce the chances of passengers escaping.

[0050] Please see Figure 1 and Figure 2 , Figure 2 This is a structural diagram of a skylight provided in one embodiment of this application.

[0051] Based on this, this application provides a sunroof 101, which includes a sunroof glass 1011 and an escape device 100. The escape device 100 is installed on the sunroof glass 1011. The escape device 100 can break the sunroof glass 1011 in the absence of power supply, so as to solve the problem that the sunroof 101 cannot be opened after the vehicle 1000 falls into water.

[0052] In this embodiment, the escape device 100 is installed at the corner of the sunroof glass 1011. By triggering the escape device 100, the user can break the sunroof glass 1011 to create an escape passage. In other embodiments, the escape device 100 can be installed at other locations on the sunroof glass 1011, and this application does not impose any restrictions on this.

[0053] In this embodiment, a gasket 1012 is provided between the escape device 100 and the sunroof glass 1011. The gasket 1012 is used to form a sealed connection between the sunroof glass 1011 and the escape device 100, and also to buffer the impact of the sunroof 101 shaking on the escape device 100. The gasket 1012 has a connecting hole so that the escape device 100 can act on the sunroof glass 1011 through the connecting hole after being triggered.

[0054] In this embodiment, the escape device 100 is small in size and can be fixed in the black edge area of ​​the sunroof glass 1011, which can reduce the impact of the escape device 100 on the appearance of the sunroof 101.

[0055] Please see Figures 1 to 5 , Figure 3 This is an assembly diagram of an escape device provided in one embodiment of this application, viewed from a first perspective. Figure 4 This is an assembly diagram of an escape device provided in one embodiment of this application, viewed from a second perspective. Figure 5 This is an exploded view of an escape device provided in one embodiment of this application.

[0056] This application provides an escape device 100, which includes a gas generator 10, an electric generator 20, a first housing 30, a first elastic element 40, a second elastic element 50, a second housing 60, and a wire 70. The gas generator 10 includes a combustible material 11, a bushing 12, a lower cover 13, and a sealing ring 14. The electric generator 20 includes a piezoelectric element 21, a hammer 22, an upper cover 23, and an operating element 24.

[0057] Specifically, the upper cover 23 is connected to the first housing 30 by a snap-fit ​​and is fixedly connected to the operating member 24. The operating member 24 can drive the upper cover 23 to move within the sliding groove of the first housing 30. The first elastic member 40 is arranged inside the upper cover 23, with one end connected to the upper cover 23 and the other end connected to the hammer 22. The two ends of the hammer 22 are connected to the first elastic member 40 and the second elastic member 50, respectively. The elastic force of the first elastic member 40 is greater than that of the second elastic member 50, allowing the hammer 22 to move up and down and rotate at a certain angle within the first housing 30. One end of the second elastic member 50 is connected to the hammer 22, and the other end is connected to the piezoelectric member 21. After the hammer 22 strikes the piezoelectric member 21, the second elastic member 50 pushes the hammer 22 to reset. The two ends of the wire 70 are connected to the piezoelectric element 21 and the combustible material 11 of the gas generator 10, respectively. After the piezoelectric element 21 is squeezed and discharged, the voltage is transmitted to the combustible material 11 of the gas generator 10 through the wire 70. The gasket 1012 is located between the second housing 60 and the skylight glass 1011 to ensure the seal between the second housing 60 and the skylight glass 1011. The first housing 30 and the second housing 60 are integrally formed and serve as the main supporting components of the escape device 100. The first housing 30 and the second housing 60 are respectively supported by the load-bearing generator and the gas generator 10. The combustible material 11 is located in the cavity of the bushing 12. After being ignited by the combustible material 11, it can quickly generate a large amount of gas. The bushing 12 is used to protect the combustible material 11 and provide combustion space for the combustible material 11. It has a conical cavity inside and a small nozzle 123 near the skylight glass 1011. The gas impacts the glass surface through the nozzle 123. The sealing ring 14 is located at the gap between the second housing 60 and the bushing 12, serving a sealing function. The lower cover 13 is connected to the second housing 60 by threads, and the lower cover 13 is used to fix the bushing 12 and the combustible material 11. At the same time, the lower cover 13 compresses the sealing ring 14 to ensure the sealing of the bushing 12. One end of the operating component 24 is fixed to the upper cover 23, and the other end can be provided with an annular buckle. The operating component 24 can be fixed to the inner wall of the roof 103 of the vehicle 1000. Pulling the operating component 24 can move the upper cover 23, thereby triggering the window-breaking function of the escape device 100. The piezoelectric component 21 is fixed inside the first housing 30. After being subjected to mechanical impact, the piezoelectric component 21 releases voltage instantaneously, and discharges through the wire 70 in the cavity of the bushing 12, igniting the combustible material 11 to generate high-pressure gas.

[0058] In one embodiment, the escape device 100 includes a gas generator 10 and an electric generator 20. The gas generator 10 contains a flammable material 11. The electric generator 20 includes a piezoelectric element 21 and a hammer 22. The hammer 22 strikes the piezoelectric element 21 to generate voltage and form an electric spark, which ignites the flammable material 11. After combustion, the flammable material 11 generates a large amount of gas. This gas passes through the connecting hole of the gasket 1012 and acts on the sunroof glass 1011, thereby breaking the sunroof glass 1011 and creating an escape passage.

[0059] In this embodiment, the piezoelectric element 21 is a piezoelectric ceramic. In other embodiments, the piezoelectric element 21 can be other piezoelectric materials. In this embodiment, the combustible material 11 is a combustible gas, such as methane, ethane, propane, ethylene, acetylene, etc. In other embodiments, the combustible material 11 can be a liquid or a solid, and this application does not limit this.

[0060] The escape device 100, sunroof 101, and vehicle 1000 provided in this embodiment utilize a passenger-driven hammer 22 to strike a piezoelectric element 21, causing the piezoelectric element 21 to generate voltage and form an electric spark. This electric spark ignites the combustible material 11 within the gas generator 10, forming gas. The gas then impacts the sunroof glass 1011, achieving a window-breaking effect. The escape device 100 provided in this application does not require connection to an onboard power source or a portable power source, avoiding situations where the escape device 100 malfunctions due to power supply issues. This improves the stability and reliability of the escape device 100, thereby increasing the survival rate of passengers who need to break the window to escape in an emergency.

Figure 12 yes Figure 6 The escape device shown is a cross-sectional view in the CC direction.

[0062] In one embodiment, the escape device 100 further includes a first housing 30 having a first receiving cavity 31. A piezoelectric element 21 is received and fixed within the first receiving cavity 31, and a hammer 22 is in movable contact with the piezoelectric element 21. The electric generator 20 further includes a top cover 23 and an operating member 24. One end of the top cover 23 is received within the first receiving cavity 31 and is movably connected to the first housing 30. The hammer 22 is connected to the top cover 23, and the operating member 24 is fixedly connected to the top cover 23.

[0063] The escape device 100 provided in this embodiment is sequentially connected via an operating component 24, a top cover 23, and a hammer 22. Passengers can drive the operating component 24 to move the top cover 23, which in turn drives the hammer 22 to strike the piezoelectric component 21, thereby triggering the window-breaking function of the escape device 100. In an emergency, passengers can activate the escape device 100 simply by pulling the operating component 24, making it easy for passengers to operate.

[0064] In one specific embodiment, the upper cover 23 has a receiving cavity 231 and a through hole 232, which are connected. The through hole 232 penetrates to form a receiving sidewall. The hammer 22 includes a first part 221 and a second part 222 connected together. The first part 221 is received within the receiving cavity 231, and the second part 222 movably passes through the through hole 232 and extends out of the through hole 232. The first housing 30 has a first opening 32 and a notch 33. The first opening 32 is connected to the first receiving cavity 31, and the notch 33 is located at the first opening 32. The escape device 100 includes a first state and a second state. The first state is the initial state of the escape device 100, that is, in the first state, the hammer 22 and the piezoelectric element 21 are spaced apart. The second state is the triggered state of the escape device 100, that is, in the second state, the hammer 22 strikes the piezoelectric element 21 to generate electricity, at which time the escape device 100 has a window-breaking function. When the top cover 23 moves toward the piezoelectric element 21, the escape device 100 switches from a first state to a second state. In the first state, the second part 222 abuts against the first opening 32 of the first housing 30, and the second part 222 is located outside the notch 33. At this time, the first part 221 and the piezoelectric element 21 are spaced apart. During the process of the escape device 100 switching from the first state to the second state, the top cover 23 moves toward the piezoelectric element 21, and the second part 222 moves from the first opening 32 of the first housing 30 toward the opening of the notch 33. In the second state, the second part 222 moves from the opening of the first opening 32 corresponding to the opening of the notch 33 into the notch 33, and the first part 221 is located inside the notch 33. At this time, the first part 221 abuts against the piezoelectric element 21. After the escape device 100 switches from the first state to the second state, the first part 221 impacts the piezoelectric element 21, causing the piezoelectric element 21 to deform and generate electrical energy.

[0065] The escape device 100 provided in this embodiment has the following characteristics: In its first state, the second part 222 abuts against the first opening 32 of the first housing 30, and the second part 222 is located outside the notch 33. At this time, the first part 221 and the piezoelectric element 21 are spaced apart. The second part 222 of the hammer 22 abuts against the periphery of the first opening 32 of the first housing 30, so that the escape device 100 can stably maintain the first state, thereby improving the stability of the escape device 100 without external drive. At the same time, by providing the notch 33 on the first housing 30, in the second state, the second part 222 moves from the first opening 32 into the notch 33, and the first part 221 is located inside the notch 33. At this time, the first part 221 abuts against the piezoelectric element 21. When the escape device 100 is driven by an external force, it quickly switches from the first state to the second state, so that the escape device 100 can break a window, thereby opening the skylight 101 to form an escape passage, which helps to improve the survival rate of passengers who need to break the window to escape in an emergency.

[0066] In one embodiment, the electric generator 20 further includes a first elastic element 40, which, in a first state, is elastically compressed between the upper cover 23 and the first portion 221 of the hammer 22. When the escape device 100 switches from the first state to the second state, the first elastic element 40 provides an elastic force to the first portion 221 of the hammer 22, causing the first portion 221 of the hammer 22 to strike the piezoelectric element 21.

[0067] In this embodiment, the first elastic element 40 is a storage spring. In the first state, the first elastic element 40 is elastically compressed between the upper cover 23 and the first part 221 and completes the storage of force. When the escape device 100 switches from the first state to the second state, the second part 222 of the hammer 22 falls from the periphery of the first opening 32 of the first housing 30 into the notch 33. In addition, the elastic force of the first elastic element 40 acts on the first part 221 of the hammer 22, so that the second part 222 of the hammer 22 quickly moves from the opening of the notch 33 to the bottom of the notch 33. At the same time, the first part 221 also quickly strikes the piezoelectric element 21 under the action of the elastic force of the first elastic element 40, so that the piezoelectric element 21 generates voltage.

[0068] The escape device 100 provided in this embodiment, through the setting of the first elastic member 40, enables the escape device 100 to quickly switch from the first state to the second state. Moreover, during the process of switching from the first state to the second state, the passenger only needs to drive the operating member 24 once to move the upper cover 23 toward the piezoelectric member 21. That is, the passenger only needs to use the first inclined wall 2321 of the upper cover 23 to squeeze the second part 222 of the hammer 22 to the opening of the notch 33. As for the movement of the second part 222 of the hammer 22 within the notch 33, no manual operation is required by the passenger. The elastic force of the first elastic member 40 can drive the second part 222 of the hammer 22 to move within the notch 33. That is, the elastic force of the first elastic member 40 drives the first part 221 of the hammer 22 to strike the piezoelectric member 21. Therefore, by setting the first elastic element 40, during the process of the escape device 100 switching from the first state to the second state, the passenger only needs to drive the operating element 24 once in a short period of time, without having to continuously drive the operating element 24. This reduces the time the passenger has to operate the escape device 100, thus providing the passenger with more escape time in an emergency and improving the passenger's chances of survival if they need to break the window to escape in an emergency.

[0069] In one embodiment, the electric generator 20 further includes a second elastic element 50, which, in a second state, is elastically compressed between the second portion 222 of the hammer 22 and the piezoelectric element 21. When the first portion 221 of the hammer 22 strikes the piezoelectric element 21, the second elastic element 50 provides elastic force to the first portion 221 of the hammer 22 and the top cover 23, causing both the first portion 221 of the hammer 22 and the top cover 23 to move away from the piezoelectric element 21, and pushing the second portion 222 of the hammer 22 out of the notch 33, so that the second portion 222 of the hammer 22 ultimately abuts against the periphery of the first opening 32 of the first housing 30.

[0070] In this embodiment, the second elastic element 50 is a return spring. In the second state, the second elastic element 50 is elastically compressed between the piezoelectric element 21 and the first part 221 and completes the storage of force. When the escape device 100 needs to switch from the second state to the first state, since the second part 222 of the hammer 22 falls from the periphery of the first opening 32 of the first housing 30 into the notch 33, the elastic force of the second elastic element 50 acts on the first part 221 of the hammer 22, so that the second part 222 of the hammer 22 quickly moves from the bottom of the notch 33 to the opening of the notch 33. At the same time, the first part 221 also moves away from the piezoelectric element 21 under the action of the elastic force of the first elastic element 40, so that the escape device 100 resets, that is, the escape device 100 returns from the second state to the first state.

[0071] The escape device 100 provided in this embodiment, through the provision of the second elastic element 50, allows the escape device 100 to switch from a second state to a first state under the action of the second elastic element 50. That is, when the escape device 100 triggers the window-breaking function, it can reset, giving the escape device 100 a recyclable function. This means that after replacing the gas generator 10, the escape device 100 can be reused, improving its reuse rate. Simultaneously, due to the provision of the second elastic element 50, passengers do not need to manually switch the escape device 100 from the second state to the first state, reducing passenger operation and thus achieving the automatic reset function of the escape device 100.

[0072] In one specific embodiment, the inner wall of the through hole 232 forming the first housing 30 includes a first inclined wall 2321. During the process of the upper cover 23 moving toward the piezoelectric element 21, the first inclined wall 2321 is used to squeeze the second part 222 of the hammer 22 so that the second part 222 of the hammer 22 falls into the notch 33 from the first opening 32. At this time, the first part 221 of the hammer 22 also moves toward the piezoelectric element 21 and strikes the piezoelectric element 21 to form a voltage.

[0073] It should be understood that the second part 222 of the hammer 22 can move within the through hole 232, and the first part 221 can move within the receiving cavity 231 of the upper cover 23. As the upper cover 23 moves toward the piezoelectric element 21, the through hole 232 of the upper cover 23 gradually enters the first receiving cavity 31 of the first housing 30, and the through hole 232 of the upper cover 23 can communicate with the notch 33 during this movement. Simultaneously, as the upper cover 23 moves toward the piezoelectric element 21, the first inclined wall 2321 will compress the second part 222 of the hammer 22, causing it to move toward the notch 33 and eventually fall into it. As the second part 222 of the hammer 22 moves from the opening of the notch 33 to the bottom of the notch 33, the corresponding first part 221 will also move toward the piezoelectric element 21 within the receiving cavity 231 of the upper cover 23, and ultimately impact the piezoelectric element 21 to generate voltage.

[0074] The escape device 100 provided in this embodiment utilizes a first inclined wall 2321 on the inner sidewall of the first housing 30. This inclined wall 2321 compresses the second part 222 of the hammer 22 from the first opening 32 of the first housing 30 into the notch 33 of the first housing 30, thereby switching the escape device 100 from a first state to a second state. This simplifies the structure for switching the escape device 100 from the first state to the second state, and eliminates the need for passengers to perform cumbersome operations, making it easier for passengers to activate the escape device 100.

[0075] In one specific embodiment, the inner wall forming the through hole 232 further includes a second inclined wall 2322, which is closer to the piezoelectric element 21 than the first inclined wall 2321. During the movement of the upper cover 23 away from the piezoelectric element 21, the second inclined wall 2322 compresses the second portion 222 of the hammer 22, causing the second portion 222 of the hammer 22 to move from the bottom of the notch 33 to the opening of the notch 33, and then to the edge of the first opening 32, thereby switching the escape device 100 from the second state to the first state and maintaining stability.

[0076] The escape device 100 provided in this application forms a second inclined wall 2322 on the inner sidewall of the through hole 232. Under the action of the second elastic member 50, the second inclined wall 2322 is used to squeeze the second part 222 of the hammer 22, so that the second part 222 of the hammer 22 moves from the bottom of the notch 33 to the opening of the notch 33, and then moves to the edge of the first opening 32, so that the escape device 100 can be reset.

[0077] In this more specific embodiment, the through hole 232 is parallelogram-shaped, and the notch 33 is rectangular. The first inclined wall 2321 is located in the through hole 232 away from the piezoelectric element 21, and the second inclined wall 2322 is located in the through hole 232 closer to the piezoelectric element 21. When the escape device 100 is in the first state, the through hole 232 and the notch 33 are isolated from each other. During the transition from the first state to the second state, the through hole 232 and the notch 33 gradually approach each other until they connect. Under the action of the first inclined wall 2321 and the first elastic element 40, the second part 222 of the hammer 22 falls from the through hole 232 into the notch 33. When the escape device 100 is in the second state, the second part 222 of the hammer 22 is simultaneously located within both the through hole 232 and the notch 33. During the process of the escape device 100 switching from the second day state to the first state, the through hole 232 and the notch 33 move further apart until they are separated. Under the action of the second inclined wall 2322 and the second elastic member 50 of the through hole 232, the first part 221 of the hammer 22 is exposed from the notch 33 and abuts against the edge of the first opening 32 of the first housing 30, so that the escape device 100 remains stable in the first state.

[0078] In one embodiment, the escape device 100 further includes a second housing 60 connected to the first housing 30, the second housing 60 having a second receiving cavity 61. The gas generator 10 is received and fixed within the second receiving cavity 61. The first housing 30 and the second housing 60 are integrally formed. The arrangement of the first housing 30 and the second housing 60 separates the gas generator 10 and the electric generator 20, which helps reduce mutual interference between them, thereby improving the operational stability of each. The escape device 100 also includes a wire 70, one end of which is located within the first receiving cavity 31 and electrically connected to the piezoelectric element 21, and the other end of which is located within the second receiving cavity 61 and electrically connected to the gas generator 10. By setting the wire 70, the voltage generated by the piezoelectric element 21 housed in the first receiving cavity 31 under the impact of the hammer 22 is transmitted through the wire 70 to form an electric spark. The wire 70 is also connected to the combustible material 11 in the gas generator 10, so that the voltage generated by the piezoelectric element 21 is transmitted through the wire 70 to ignite the combustible material 11, thereby forming a large amount of gas for impacting the sunroof glass 1011.

[0079] In one embodiment, the gas generator 10 includes a bushing 12 housed within a second receiving cavity 61. A first annular step 62 is provided on the inner wall of one end of the second housing 60, and a second annular step 121 is provided on the outer wall of one end of the bushing 12. The first annular step 62 and the second annular step 121 abut against each other to engage the bushing 12 with the second housing 60 and to limit the bushing 12's position. The bushing 12 has a reaction chamber 122, within which a combustible material 11 is housed. The other end of a wire 70 passes through the bushing 12 and is located within the reaction chamber 122, with the other end of the wire 70 in contact with the combustible material 11.

[0080] In this embodiment, the first annular step 62 of the second housing 60 cooperates with the second annular step 121 of the bushing 12 to stably install the bushing 12 within the second receiving cavity 61, which helps improve the installation stability of the gas generator 10 within the second receiving cavity 61. Furthermore, the combustible material 11 is ignited within the reaction chamber 122 of the bushing 12, forming a large amount of gas. The reaction chamber 122 of the bushing 12 provides a stable combustion environment for the combustible material 11, thereby making the gas formed by the combustible material 11 more stable, thus improving the stability of the escape device 100 against damage to the skylight glass 1011.

[0081] In one embodiment, the second receiving cavity 61 penetrates the second housing 60, and the reaction cavity 122 penetrates the bushing 12. The gas generator 10 also includes a lower cover 13 and a sealing ring 14. The lower cover 13 is disposed on the end of the second housing 60 opposite to the first annular step 62, and the sealing ring 14 is disposed between the bushing 12 opposite to the second annular step 121 and the lower cover 13. The sealing ring 14 is used to seal the reaction cavity 122 and the second receiving cavity 61.

[0082] In this embodiment, the lower cover 13 is placed on the side of the second housing 60 opposite to the first annular step 62, which improves the stability of the bushing 12 housed in the second receiving cavity 61, thereby improving the stability of the combustion of the combustible material 11 within the bushing 12. Furthermore, the sealing ring 14, positioned between the bushing 12 and the lower cover 13, forms a seal between the reaction chamber 122 and the second receiving cavity 61. This prevents the gas generated by the combustion of the combustible material in the reaction chamber 122 from flowing out of the second receiving cavity 61, ensuring the amount of gas that the escape device 100 applies to the skylight glass 1011, and thus ensuring the stability of the window-breaking function of the escape device 100.

[0083] In one specific embodiment, the combustible material 11 burns and forms gas in the reaction chamber 122. Simultaneously, a nozzle 123 is provided on the bushing 12, connecting the reaction chamber 122 to the outside of the second housing 60. The nozzle 123 is used to collect the gas formed after the combustible material 11 burns, so as to release the gas from the outside of the second housing 60. By setting the nozzle 123 to collect and spray the gas formed after the combustible material 11 burns and acts on the skylight glass 1011, it is beneficial to improve the effect of the gas formed by the combustion of the combustible material 11 on the skylight 101, thereby improving the window-breaking effect of the escape device 100 on the skylight glass 1011.

[0084] In a more specific embodiment, the inner diameter of the nozzle 123 gradually decreases from the end of the nozzle 123 near the reaction chamber 122 to the end of the nozzle 123 away from the reaction chamber 122. The nozzle 123 is conical in shape so that the gas generated after the combustion of the combustible material 11 is released through the nozzle 123 to form high-pressure gas. This high-pressure gas can effectively shatter the sunroof glass 1011, ensuring the window-breaking effect of the gas generating device on the sunroof glass 1011 and improving the window-breaking effect of the escape device 100 on the sunroof glass 1011.

[0085] The above are some embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
