Description

Technical Field

[0001] This invention belongs to the field of automotive safety technology, and more specifically, relates to an escape glass device for vehicles based on the expansion of quicklime through hydration. Background Technology

[0002] When a car is flooded, has a faulty electrical system, or is deformed from a collision and the doors cannot be opened, the situation is extremely urgent. Escaping through the car window can be an important way to escape, and time is the first line of defense. Existing conventional methods of breaking windows: 1. First, try the electronic switches. Immediately press all the electronic switches on the windows. When the vehicle is first submerged in water, the circuit may still have a brief residual power supply, but this method will fail once the circuit is dead. For example, there is a patented self-exploding escape window for buses: this window is designed to activate in case of fire by using a salt spray sensor and a pulse signal from the main control chip to initiate electronic ignition, which then detonates the window, allowing for escape. Therefore, this device cannot function if the circuit fails or the entire vehicle is submerged in water and loses power. 2. Break the car window with a safety hammer, which is the most common way to break a window. Disadvantages include: it is difficult to find in an emergency if the storage location is not right; hitting the wrong spot in a panic (the correct way is to hit the four corners, not the center) will not break the window; it is difficult to use underwater, as breaking windows is difficult in underwater resistance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a vehicle escape glass device based on the expansion of quicklime hydration, so that when the vehicle loses power, is submerged in water or other external factors prevent the doors and windows from being opened normally, the vehicle glass will spontaneously explode by the quicklime hydration reaction, thus buying time for the escapee to survive.

[0004] The aforementioned vehicle escape glass device based on the hydration expansion of quicklime includes a lifting mechanism and a vehicle glass, wherein the vehicle glass and the lifting mechanism are fitted together. The device is characterized in that: a filling cavity is provided at the bottom edge of the vehicle glass, and the filling cavity is filled with quicklime powder; a connecting device is fixed to the bottom of the vehicle glass, and the other end of the connecting device is connected to a liquid storage device.

[0005] Preferably, the bottom of the vehicle glass is provided with multiple connecting holes, one end of which is connected to the filling cavity and the other end is connected to the bottom of the vehicle glass and fixedly connected to the connecting device.

[0006] Preferably, the connecting device includes a connecting end, a connecting pipe, and a starting valve. The number of connecting ends is adapted to the number of connecting holes, and one end of the connecting end is fixedly connected to the connecting hole. The connecting pipe has multiple branch pipes in the middle, and the branch pipes are fixedly connected to the connecting end. The starting valve is fixed in series in the middle of the connecting pipe.

[0007] Preferably, a one-way valve is fixed between the branch pipe and the starting valve, and the flow direction is towards the branch pipe.

[0008] Preferably, the connecting end is provided with a sealing component to prevent lime powder from entering the branch pipe and to cut off the water flow of the liquid storage device.

[0009] Preferably, the sealing assembly includes a bracket, a tension spring, and a sealing plate. The bracket is fixedly connected to the inner wall of the connecting end. The sealing plate is embedded in the end of the connecting end facing the filling cavity.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] like Figures 1 to 3 As shown, a vehicle escape window device based on the hydration expansion of quicklime includes a lifting mechanism 1 and a vehicle window 2, with the vehicle window 2 and the lifting mechanism 1 fitted together. The device is characterized by: a filling cavity 3 located near the edge of the bottom of the vehicle window 2, filled with quicklime powder 31; a connecting device 4 fixed to the bottom of the vehicle window 2, with the other end of the connecting device 4 connected to a liquid storage device 9. Thus, when the vehicle cannot open its doors or the vehicle window 2 due to accidents such as water wading or collisions causing electrical equipment failure or body deformation, this device can be activated. The stored water in the liquid storage device 9 flows into the filling cavity 3 under the influence of gravity and pressure difference, causing the quicklime to undergo a hydration reaction. When the stored water comes into contact with the quicklime powder 31, a chemical reaction occurs (CaO + H2O = Ca(OH)2), which is essentially the transformation of quicklime into slaked lime. During the transformation process of the quicklime powder 31, its volume gradually expands to 2 to 3 times its original volume. Relying on the expansion force of the hydration reaction of lime powder 31 and the high-temperature steam generated during the hydration reaction, the pressure inside the filling cavity 3 rises sharply, which is enough to break through the weak point between the filling cavity 3 and the outer wall of the car glass 2, thereby achieving the purpose of automatic explosion of the car glass 2, enabling the people inside the car to save themselves or providing rescue space for rescuers outside the car.

[0019] like Figure 1 and Figure 2 As shown, the filling cavity 3 is located at the bottom of the vehicle glass 2, near the connection between the vehicle glass 2 and the lifting mechanism 1. This ensures that the lime powder 31 in the filling cavity 3 remains inside the door during the hydration reaction. This minimizes the risk of injury to occupants from the high-temperature steam generated by the hydration reaction of the lime powder 31 and the instantaneous pressure release during automatic explosion, thus improving self-rescue safety. Furthermore, the filling cavity 3's location at the connection between the vehicle glass 2 and the lifting mechanism 1 allows the vehicle glass 2 to detach completely from the lifting mechanism 1 after its complete explosion, enabling it to be easily pushed outwards, further increasing the success rate of self-rescue.

[0020] like Figure 2 and Figure 3As shown, the bottom of the vehicle glass 2 is provided with multiple connecting holes 21, one end of which communicates with the filling cavity 3, and the other end communicates with the bottom of the vehicle glass 2 and is fixedly connected to the connecting device 4. In this way, by providing multiple connecting holes 21 at the bottom of the glass that communicate with the filling cavity 3, stored water can be injected into the filling cavity 3 simultaneously from multiple points, thereby achieving a multi-point synchronous hydration reaction of the lime powder 31. This further improves the overall reaction speed within the filling cavity 3, making the explosion of the vehicle glass 2 more rapid compared to single-point injection.

[0021] like Figure 2 As shown, the connecting device 4 includes connecting ends 5, connecting pipes 6, and starting valves 7. The number of connecting ends 5 matches the number of connecting holes 21, and one end of each connecting end 5 is fixedly connected to a connecting hole 21. Multiple branch pipes 61 are provided in the middle of the connecting pipe 6, and the branch pipes 61 are fixedly connected to the connecting ends 5. The starting valves 7 are fixed in series in the middle of the connecting pipe 6. Thus, the connecting pipe 6 forms multiple storage water delivery branches through the branch pipes 61, which, in conjunction with the connecting holes 21, realize multi-point synchronous delivery of the filling chamber 3.

[0022] like Figure 2 and Figure 3 As shown, a one-way valve 8 is also fixed between the branch pipe 61 and the starting valve 7, with the flow direction facing the branch pipe 61. In this way, the one-way valve 8 ensures that the stored water always flows towards the vehicle glass 2, avoiding the problem of insufficient water injection into the filling chamber 3 due to backflow.

[0023] like Figure 4 As shown, the connecting end 5 is equipped with a sealing component 51 to prevent lime powder 31 from entering the branch pipe 61 and to cut off the water flow from the liquid storage device 9. In this way, the sealing component 51 can seal the connection between the connecting end 5 and the filling cavity 3 in non-emergency situations, preventing lime powder 31 from entering the branch pipe 61 or the connecting pipe 6 and causing blockage, thus ensuring the unobstructed flow of the branch pipe 61 and the connecting pipe 6. On the other hand, when a certain injection point of lime powder 31 in the filling cavity 3 has absorbed enough reserve water and undergone sufficient reaction and expansion, the expansion force can re-seal the sealing component 51, allowing the reserve water to flow fully to other injection points.

[0024] like Figure 4As shown, the sealing assembly 51 includes a bracket 511, a tension spring 512, and a sealing plate 513. The bracket 511 is fixedly connected to the inner wall of the connecting end 5; the sealing plate 513 is embedded in the end of the connecting end 5 facing the filling cavity 3; the tension spring 512 is disposed between the bracket 511 and the sealing plate 513, and is fixedly connected to both the bracket 511 and the tension spring 512. Thus, in the initial stage of device startup, the injection pressure of the stored water is greater than the tension force of the spring on the sealing plate 513. Therefore, the stored water, by its injection pressure, can push the sealing plate 513 open, injecting water into the filling cavity 3, allowing the lime powder 31 to undergo a sufficient hydration reaction. When the lime powder 31 in the filling cavity 3 has fully reacted and expanded, its expansion force is greater than the injection force of the stored water. Therefore, the lime powder 31, by its expansion force, pushes the sealing plate 513 back into the connecting end 5, thereby enabling the continued injection of stored water, allowing the stored water to flow to other injection points, ensuring that other injection points receive sufficient stored water for a complete reaction.

[0025] Optionally, the liquid storage device 9 is filled with water and inert gas. In this way, by injecting an inert gas (including but not limited to helium) at a certain pressure into the liquid storage device 9, the liquid storage device 9 does not rely solely on gravity. Under the pressure of the inert gas, the stored water in the liquid storage device 9 can be rapidly injected, improving the reaction efficiency of the lime powder 31, and thus increasing the explosion speed of the vehicle glass 2.

[0026] like Figure 2 and Figure 3 As shown, the side wall of the vehicle glass 2 is provided with a through hole 22 communicating with the filling cavity 3, and a sealing plug 32 is fixed inside the through hole 22. In this way, the lime powder 31 can be quickly filled during the production process of the vehicle glass 2 through the through hole 22 connected to the filling cavity 3, which not only reduces the production difficulty but also improves production efficiency. At the same time, the sealing plug 32 effectively seals the through hole 22, preventing the lime powder 31 in the filling cavity 3 from leaking out through the through hole 22 during the hydration reaction and expansion process, thereby ensuring the expansion pressure inside the filling cavity 3.

[0027] like Figure 3 As shown, the sealing plug 32 has a vent 321 in the middle. In this way, when the stored water is injected into the filling cavity 3 through the vent 321, the air in the connecting pipe 6, branch pipe 61 and filling cavity 3 can be quickly squeezed out, avoiding the situation where the air in the filling cavity 3 cannot be expelled and forms a blockage effect, which would prevent the stored water from being injected into the filling cavity 3 normally.

[0028] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
