Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle safety emergency, in particular to a vehicle safety emergency device based on land and water dual scenes. BACKGROUND

[0002] With the continuous growth of the number of cars and the increasing complexity of driving environment, the importance of vehicle safety emergency device is increasingly prominent. Currently, vehicle safety technology mainly focuses on the prevention and response of land traffic accidents, such as airbags, pre-tensioning seat belts and other systems, which have achieved remarkable results in reducing collision damage. However, when a vehicle encounters a special emergency such as falling into water, the existing technology often fails to provide timely and effective escape assistance, especially under the interaction of land and water dual scenes, i.e. when a vehicle faces both land collision risk and water falling threat, the limitations of traditional vehicle safety emergency devices are particularly prominent, and they cannot fully meet the survival needs of passengers in extreme environments.

[0003] However, when a vehicle falls into water accidentally, there is a lack of vehicle safety emergency device that can quickly trigger and continuously provide stable buoyancy support, while having high visibility warning function. Specifically, traditional devices focus more on the response to land collision in design, and do not consider the special needs in the water falling scene. For example, the underwater environment puts higher requirements on the reliability of the device triggering mechanism, and water pressure may hinder the normal start of the device. At the same time, the light is seriously attenuated under water, and the traditional warning signal is difficult to effectively penetrate the water surface, making it difficult for external rescue to quickly locate. This defect directly limits the self-rescue and mutual rescue ability of passengers after falling into water, increasing the risk of drowning. Therefore, it needs to be improved. SUMMARY

[0004] The purpose of the present application is to provide a vehicle safety emergency device based on land and water dual scenes, to solve the problem that there is a lack of vehicle safety emergency device that can quickly trigger, continuously provide stable buoyancy support and have high visibility warning function when a vehicle falls into water in the prior art.

DETAILED DESCRIPTION

[0033] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0034] As shown in the accompanying Figure 1 to the accompanying Figure 9 drawings:

[0035] Embodiment one:

[0036] The present application provides a vehicle-mounted safety emergency device based on land and water double scenes, which comprises a control box 1, the inner wall of the control box 1 is provided with an assembly box 2, the inner wall of the assembly box 2 is provided with a partition frame 3, the bottom of the partition frame 3 is provided with a sealing gasket 4, the top of the assembly box 2 is provided with a plurality of telescopic mechanisms, the output end of the telescopic mechanism is provided with an impact rod 5, and the sealing gasket 4 is knocked off from the bottom of the partition frame 3 when the impact rod 5 moves downward;

[0037] The surface bottom of the assembly box 2 is provided with a connecting pipe 6, one end of the connecting pipe 6 is provided with a Venturi tube, the other end of the connecting pipe 6 is provided with an air pipe 7, and the two ends of the air pipe 7 are both provided with a one-way valve;

[0038] The bottom end of the air pipe 7 is provided with an arc-shaped air bag 8, the inner bottom wall of the arc-shaped air bag 8 is provided with a counterweight 9, the top end of the air pipe 7 is provided with a cylindrical air bag 10, and the inner wall of the cylindrical air bag 10 is provided with a plurality of lamp strips 11;

[0039] The inner wall of the control box 1 is provided with a collision sensor 12. When the collision sensor 12 receives a collision signal, the telescopic mechanism will move downward.

[0040] A plurality of positioning tubes 13 are mounted on the top of the assembly box 2. The inner wall of the positioning tube 13 is provided with a connecting rope 14. The inner wall of the positioning tube 13 is provided with a driving mechanism 15. The output end of the driving mechanism 15 is provided with an arc-shaped cutting knife 16.

[0041] A sleeving tube 17 is mounted on the top of the assembly box 2. The inner wall of the sleeving tube 17 is sleeved with the top end of the impact rod 5. The top end of the impact rod 5 is provided with a limiting plate 18. The surface of the limiting plate 18 is sleeved with the inner wall of the sleeving tube 17.

[0042] The top of the limiting plate 18 is provided with an extrusion spring 19. The top of the limiting plate 18 is mounted on the bottom end of the connecting rope 14. The surface of the connecting rope 14 is sleeved with the inner wall of the extrusion spring 19.

[0043] The positioning tube 13, the connecting rope 14, the driving mechanism 15, the arc-shaped cutting knife 16, the sleeving tube 17, the limiting plate 18 and the extrusion spring 19 jointly compose a telescopic mechanism.

[0044] In use, the control box 1 as a whole carries and protects the structure, and the assembly box 2 inside is integrated as the installation basis of the core reaction and execution unit. The partition frame 3 inside the assembly box 2 is divided into three parallel chambers from left to right, which store solid citric acid, solid sodium bicarbonate and water as a trigger agent respectively, and the three are in isolation state at ordinary times. The bottom of the partition frame 3 is closed by a sealing gasket 4 to ensure that the materials remain stable in the non-trigger state. When the vehicle collides, the collision sensor 12 receives the signal and triggers the action of multiple telescopic mechanisms. Each telescopic mechanism is composed of a positioning tube 13, a connecting rope 14, a driving mechanism 15, an arc-shaped cutting knife 16, a sleeve pipe 17, a limiting plate 18 and an extrusion spring 19. After the driving mechanism 15 (which can be a servo motor) is started, it drives the arc-shaped cutting knife 16 to cut the connecting rope 14, thereby releasing the constraint on the extrusion spring 19. The spring quickly releases the elastic force, pushing the limiting plate 18 and the impact rod 5 connected thereto to move quickly downward along the sleeve pipe 17. The end of the impact rod 5 impacts the sealing gasket 4, causing it to separate from the bottom of the partition frame 3, resulting in the mixing of the three materials and the chemical reaction to produce a large amount of gas. The gas is discharged through the connecting pipe 6 at the bottom of the assembly box 2, one end of which is provided with a Venturi structure to enhance the efficiency of the gas flow, and the other end is connected to the air pipe 7, both ends of which are provided with one-way valves to ensure one-way gas flow. The gas first fills the arc-shaped air bag 8 at the bottom, and the counterweight 9 arranged on the inner bottom wall of the air bag enables the air bag to maintain a stable posture in water. The arc-shaped air bag 8 can also become a similar bottom disc as a "Tumbler" on the ground, so that the entire device remains stable and exhibits upward; then the gas continues to fill the cylindrical air bag 10 at the top, and the inner wall of the cylindrical air bag 10 is provided with a plurality of lamp strips 11 which are automatically turned on when the air bag is inflated and expanded, providing lighting and distress signal functions. Thus, the air bag system can be quickly started after the vehicle is submerged or collides, providing buoyancy support and visual warning, and enhancing the emergency escape ability of the passengers in both land and water scenes.

[0045] Example Two

[0046] This example is basically the same as the previous example, except that the top of the cylindrical air bag 10 is provided with a connecting block 20, the inner wall of the connecting block 20 is provided with a plurality of button cells, the inner bottom wall of the cylindrical air bag 10 is provided with a stop pad 21, and the surface of the stop pad 21 is inserted between the two button cells. The inner wall of the control box 1 is rotatably connected with a reel 22 around the periphery, the surface of the reel 22 is wound with a traction rope 23, and the top end of the traction rope 23 is connected to the surface of the connecting block 20.

[0047] In use, the connecting block 20 is fixed to the top of the cylindrical air bag 10, and a plurality of button cells for powering the light strip 11 are installed inside. In the initial state, the cylindrical air bag 10 is in a deflated and folded state, and the top end of the stop pad 21 installed on the inner bottom wall of the cylindrical air bag 10 is inserted between the two adjacent button cells in the connecting block 20, acting as an insulating spacer to physically block the connection circuit between the electrodes of the button cells, so that the button cells are in an open circuit state and the light strip 11 cannot be powered. At the same time, the traction rope 23 is wound around the spool 22 installed on the inner wall of the control box 1, and the top end of the traction rope 23 is fixed to the connecting block 20, which serves to store and position the cylindrical air bag 10 and the connecting block 20 in the deflated state. When the device is triggered, the gas generated by the chemical reaction fills the cylindrical air bag 10, which rapidly expands and unfolds. This expansion process generates an upward pulling force, which tightens the traction rope 23 through the connecting block 20 and drives the spool 22 to rotate and release the rope length. As the cylindrical air bag 10 is fully inflated, the connecting block 20 is lifted, causing the button cells inside to move relative to the stop pad 21, and the top end of the stop pad 21 is separated from the electrodes of the button cells. Once the insulating barrier of the stop pad 21 is removed, a conductive circuit is formed between the positive and negative electrodes of the button cells, automatically powering the multiple groups of light strips 11 installed on the inner wall of the cylindrical air bag 10, causing them to emit light.

[0048] Example Three:

[0049] This example is basically the same as the previous example, except that the inner wall of the control box 1 is installed with a telescopic rod 24, and the output end of the telescopic rod 24 is inserted through one side of the control box 1. The front end of the telescopic rod 24 is installed with a suction magnet 25, and the back of the suction magnet 25 is inserted into one side of the control box 1. The two sides of the suction magnet 25 are installed with ear hooks 26.

[0050] In use, the telescopic rod 24 is installed on the inner wall of the control box 1, and its output end is inserted through the side wall of the control box 1 and can be extended and retracted. The front end of the telescopic rod 24 is installed with a suction magnet 25, which is embedded in the groove on the side wall of the control box 1 when not in use, to maintain the compactness of the overall structure. When the vehicle encounters an emergency situation (such as falling into water or a serious collision), the device can be removed from the vehicle body or moved to a specific location (such as being absorbed on the roadside metal fence to fix the rescue position) by the vehicle occupants or rescue personnel. The suction magnet 25 can be easily pulled off the vehicle body by applying force through the ear hooks 26. Subsequently, the device can be placed at the desired location by holding or pulling it with the ear hooks 26, and then re-attached to a nearby metal body (such as a fence, metal edge of a rescue boat, etc.) with the suction magnet 25, achieving quick and reliable temporary fixation.

[0051] Application Example:

[0052] A car is driving at night and suddenly loses control and plunges into a deep river beside the road to avoid a pedestrian crossing the road. The vehicle experiences a violent impact and sinks quickly. The passengers are briefly stunned by the impact, and the vehicle's electrical system shorts out and fails after it enters the water. The car windows and doors cannot be opened normally due to water pressure, and the passengers are plunged into darkness and panic. In the emergency situation of land and water superimposed, the vehicle safety emergency device is triggered to start, providing critical escape assistance and rescue support for the passengers.

[0053] At the moment of the vehicle's violent impact with the water surface after plunging into the river, the collision sensor 12 installed on the inner wall of the control box 1 detects the strong impact signal and immediately transmits it to the telescopic mechanism. After receiving the signal, multiple sets of driving mechanisms 15 (such as micro servo motors) installed on the top of the assembly box 2 are synchronously started, driving the arc-shaped cutting knife 16 at the output end to rotate quickly, accurately cutting the connecting rope 14 that binds the compression spring 19. After the connecting rope 14 is cut, the compression spring 19, which was in a compressed state, releases its elastic potential energy instantly, pushing the limiting plate 18 connected to it to move downward at high speed along the inner wall of the sleeve pipe 17. The impact rod 5 connected to the bottom end of the limiting plate 18 is then impacted downward, and the strong impact force instantly pushes open the sealing gasket 4 at the bottom of the partition frame 3.

[0054] After the sealing gasket 4 is pushed open, the solid citric acid, solid sodium bicarbonate, and liquid water that were originally isolated in the three independent chambers of the partition frame 3 mix with each other, and a violent acid-base neutralization reaction occurs, generating a large amount of carbon dioxide gas. The generated gas is discharged outward through the connecting pipe 6 installed on the surface of the assembly box 2 under pressure. The Venturi structure at one end of the connecting pipe 6 optimizes the gas flow efficiency, and the gas then enters the air pipe 7. The one-way valves at both ends of the air pipe 7 ensure that the gas can only flow in one direction to the air bag system.

[0055] The gas first flows into the arc-shaped air bag 8 at the bottom end of the air pipe 7, causing it to expand rapidly. Since the inner bottom wall of the arc-shaped air bag 8 is installed with a counterweight 9, the air bag can always maintain a specific stable posture after it is deployed in the water, providing preliminary buoyancy support to the vehicle and helping to slow down the sinking trend of the vehicle. Then, the gas continues to fill the cylindrical air bag 10 at the top end of the air pipe 7. The expansion process of the cylindrical air bag 10 generates an upward pulling force acting on the top fixed connecting block 20. The connecting block 20 is connected to the reel 22 around the inner wall of the control box 1 through the traction rope 23. The expansion of the air bag pulls the traction rope 23, causing the reel 22 to rotate smoothly and release the length, ensuring that the cylindrical air bag 10 can expand smoothly and straight up.

[0056] When the cylindrical airbag 10 is not inflated, the top end of the stopper 21 installed on the inner bottom wall of the cylindrical airbag 10 is inserted between the two adjacent electrodes of the button cell inside the connecting block 20, forming a physical isolation, so that the circuit is in an open state. As the cylindrical airbag 10 is fully inflated, the connecting block 20 is lifted upwards, and the stopper 21 is separated from the button cell electrodes. The battery circuit is automatically connected, immediately providing power to the multiple sets of light strips 11 pre-installed on the inner wall of the cylindrical airbag 10. The light strips 11 instantly emit high-brightness light, not only illuminating the interior of the vehicle cabin and alleviating the panic of the occupants, but more importantly, providing a clear underwater positioning and distress signal to external rescuers through the window surface.

[0057] At the same time, quickly find the hanging ear 26 installed on the front end of the telescopic rod 24 on the side of the control box 1. By pulling the hanging ear 26, the telescopic rod 24 with the adsorbing magnet 25 can be pulled out from the storage position on the side wall of the control box 1. The occupants use the hanging ear 26 as a handle to take the entire device out of the car, and firmly adsorb it on the metal frame of the door with the adsorbing magnet 25. The device is stably fixed outside the car, continuously providing buoyancy markers and light signals. After the rescuers arrive at the scene, they quickly locate the accident vehicle according to the clearly visible light-emitting cylindrical airbag 10 on the water surface, and successfully implement the rescue, safely rescuing all occupants.

[0058] Working principle: when the vehicle is in collision or falls into water, the collision sensor 12 installed on the inner wall of the control box 1 receives the collision signal and triggers the telescopic mechanism to act; the telescopic mechanism is composed of the positioning pipe 13 installed on the top of the assembly box 2, the connecting rope 14 inserted into the positioning pipe 13, the driving mechanism 15, the arc-shaped cutting knife 16, the sleeve pipe 17, the limiting plate 18 at the top end of the impact rod 5, and the extrusion spring 19, after the driving mechanism 15 is started, the arc-shaped cutting knife 16 cuts off the connecting rope 14, and the constraint on the extrusion spring 19 is released, the extrusion spring 19 quickly releases the elastic force to push the limiting plate 18 and the impact rod 5 to move downward along the sleeve pipe 17 at high speed; the end of the impact rod 5 impacts the sealing gasket 4 at the bottom of the partition frame 3, so that it is separated from the partition frame 3, causing the solid citric acid, solid sodium bicarbonate and water stored in the partition frame 3 from left to right to mix and react chemically, generating a large amount of gas; the gas is discharged through the connecting pipe 6 connected to the surface of the assembly box 2, one end of the connecting pipe 6 is provided with a Venturi tube to enhance the efficiency of the gas flow, and the other end of the connecting pipe 6 is connected to the air pipe 7, both ends of the air pipe 7 are provided with one-way valves to ensure the one-way flow of the gas; the gas first fills the arc-shaped air bag 8 at the bottom end of the air pipe 7, the counterweight 9 arranged on the inner bottom wall of the air bag keeps the air bag in a stable posture in water, providing initial buoyancy; then the gas continues to fill the cylindrical air bag 10 at the top end of the air pipe 7, when the cylindrical air bag 10 expands, it pulls the traction rope 23 through the top connecting block 20, the other end of the traction rope 23 is wound on the reel 22 around the inner wall of the control box 1, the reel 22 rotates to release the length, ensuring that the air bag can be smoothly unfolded; when the cylindrical air bag 10 is not inflated, the stop pad 21 installed on the inner bottom wall of the cylindrical air bag 10 is inserted between the adjacent battery electrode terminals in the connecting block 20 to disconnect the circuit, when the air bag is inflated to lift the connecting block 20, the stop pad 21 is separated from the battery electrode terminals, and the circuit of the button cell is automatically connected, providing power for the multiple lamp strips 11 on the inner wall of the cylindrical air bag 10 to emit light, providing illumination and distress signal; in addition, the telescopic rod 24 installed on the inner wall of the control box 1 is provided with the adsorbing magnet 25 at the front end, and the magnet is provided with the hanging ears 26 on both sides, which can be pulled out of the device in emergency and fixed on the vehicle body or external metal body by using the adsorbing magnet 25; the air bag system can be quickly started after the vehicle is in collision or falls into water, stable buoyancy is provided, the lighting is automatically turned on, and the portable fixing capacity is achieved, which significantly improves the emergency escape effect in land and water scenes.
