Description

Technical Field

[0001] The present invention relates to a buoyancy generating device for a vehicle, which is detachably provided in the vehicle, separates from the vehicle when a waterlogging accident occurs, and provides buoyancy by means of a tube body that operates and expands under a simple operation by an occupant, so that the occupant can float to the water surface. Background Art

[0002] Watercraft are provided with various inflatable safety devices for dealing with safety accidents. For example, lifebuoys are provided on ships, and occupants wear life jackets when boarding, so that even those who are not proficient in swimming can float to the water surface when falling into the water.

[0003] However, when an accident occurs where a vehicle sinks into a deep river, deep lake, deep sea, etc., it may be difficult to respond appropriately in an emergency, leading to personal accidents. In particular, it is extremely rare for occupants to wear life jackets when boarding a vehicle or for lifebuoys for dealing with emergencies to be available on the vehicle. In addition, when a waterlogging accident occurs, the vehicle will sink into the water due to the weight of the vehicle body. Therefore, there may be a risk that occupants who are not proficient in swimming may be injured or killed because they cannot float to the water surface.

[0004] Life-saving devices for water use can be composed of simple structures that can float from the water by the buoyancy of gas. However, currently, buoyancy generating devices for watercraft have been developed, and there is no buoyancy generating device for vehicles suitable for vehicles. In particular, it is difficult to apply protective equipment such as lifebuoys worn by occupants in a vehicle to the vehicle.

[0005] Therefore, in order to deal with frequently occurring waterlogging accidents and urban floods that may occur in future cities, an invention is introduced here. As a buoyancy generating device for vehicles suitable for vehicles that is studied for the first time in the world, it can function as a lifebuoy when a waterlogging accident occurs. Summary of the Invention

[0006] (1) Technical Problems to be Solved

[0007] The present invention is proposed to solve the above problems, and its purpose is to provide a device provided in a vehicle that can separate from the vehicle when a waterlogging accident occurs and can expand a tube body according to a simple operation, thereby providing buoyancy that can enable an occupant to float to the water surface.

[0008] (2) Technical Solutions

[0009] To achieve the above object, the buoyancy generating device for a vehicle of the present invention may include: a housing detachably provided in the vehicle; a buoyancy generating unit provided in the housing and including a tube body that expands outwardly of the housing during expansion and a gas supply unit that supplies expansion gas to expand the tube body during operation; and a handle unit provided in the housing and providing a handle so that when the tube body expands and floats from the water by buoyancy during operation, an occupant floats with the tube body.

[0010] Among them, the pressure applied by the occupant gripping the handle unit can be transmitted to the gas supply unit, and the gas supply unit supplies expansion gas to the tube body, thereby expanding the tube body.

[0011] Among them, the handle unit may include a trigger. When the occupant applies pressure by gripping, the trigger moves in the direction of the applied external force, and when the trigger moves, the gas supply unit operates in linkage therewith.

[0012] Among them, the handle unit may include a deformable part that deforms in the direction of the applied pressure, and when the pressure applied to the trigger is transmitted to the deformable part, the volume of the deformable part decreases, and the gas supply unit receives the pressure corresponding to the decreased volume of the deformable part and operates.

[0013] Among them, a pressure transmission part may be formed inside the handle unit. The pressure transmission part is connected between the deformable part and the gas supply unit and is formed as a flow path for transmitting the pressure generated by the deformable part to the gas supply unit.

[0014] Among them, the pressure transmission part may be formed as a microtube with a narrow cross-sectional area, so as to transmit a force greater than the pressure applied to the trigger to the gas supply unit.

[0015] Among them, the deformable part may be in the form of a corrugated tube. One end of the deformable part is connected to the trigger and sealed, and the other end is connected to the pressure transmission part and sealed, so that the pressure corresponding to the decreased volume of the deformable part is transmitted to the gas supply unit without loss through the pressure transmission part.

[0016] In addition, the handle unit may include a closer. When the position connecting the gas supply unit and the tube body is subjected to a pressure exceeding a critical pressure, the closer opens, thereby supplying expansion gas to the tube body. When the gas supply unit operates and discharges the expansion gas, the closer is opened by the pressure of the expansion gas, and the expansion gas is supplied to the tube body through the closer.

[0017] Among them, the handle unit may be provided with a pressure transmission element. The pressure transmission element seals the gas supply unit outside the gas supply unit. The pressure transmission element transmits the pressure applied by the occupant when gripping the handle unit to the gas supply unit to make the gas supply unit operate, and opens the closer when the internal pressure of the gas supply unit exceeds the critical pressure.

[0018] In addition, it may further include a connecting line, one end of which is connected to the housing and the other end is connected to the vehicle body. When the tube body is deployed, it is disconnected from the housing. The connecting line is connected to the handle portion and is disconnected from the housing due to the pressure when the occupant tightly holds the handle portion.

[0019] Wherein, a tear line may be provided on the outer side surface of the housing to enable the tube body to break through the housing and expand outward when the tube body expands.

[0020] In addition, a lighting module may be provided on the housing to visually identify the position provided in the interior space of the vehicle. The lighting module may include a battery for supplying power, and the battery is charged by being connected to the connecting line.

[0021] (III) Advantageous Effects

[0022] The present invention is usually provided in a vehicle. When a waterlogging accident occurs, it is operated through a simple operation by an occupant and provides buoyancy, so that the occupant can float to the water surface in the case of a waterlogging accident. Therefore, it has the effect of being able to prevent safety accidents.

[0023] In addition, the present invention is composed of a structure for effectively transmitting the pressure generated by the occupant by holding the handle portion, has a simple structure, is easy to manufacture and use, has a low manufacturing cost, and has the advantage of being applicable to all vehicles.

[0036] For the embodiments of the present invention disclosed in this specification or application, the illustration of specific structural and functional descriptions is only for explaining the embodiments of the present invention. The embodiments of the present invention can be implemented in various ways and should not be understood as being limited to the embodiments described in this specification or application.

[0037] The embodiments of the present invention can be deformed in various ways and can have various forms. Therefore, specific embodiments are shown in the drawings and are described in detail in this specification or application. However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosure manner, but should be understood to include all changes, equivalents, and alternatives within the technical idea and technical scope of the present invention.

[0038] Terms such as "first" and / or "second" can be used to describe various components, but the components are not limited to these terms. These terms are only used to distinguish one component from other components. For example, without departing from the scope of the rights according to the concept of the present invention, the first component can be named the second component, and similarly, the second component can also be named the first component.

[0039] Next, the preferred embodiments of the present invention will be described with reference to the drawings, so as to describe the present invention in detail. The same reference numerals shown in the drawings represent the same components.

[0040] The present invention relates to a buoyancy generation device for a vehicle, which can provide buoyancy in the case of water immersion of the vehicle so that the occupants can float from the water to the water surface. Different from the existing life-saving buoyancy generation devices, this device is the world's first device built into a vehicle and capable of assisting the emergency escape of occupants in the event of a water immersion accident to prevent personal accidents.

[0041] Figure 1 is a perspective view of a buoyancy generation device for a vehicle according to an embodiment of the present invention. Refer to Figure 1 , a buoyancy generation device for a vehicle according to an embodiment of the present invention may include a housing 100, a buoyancy generation part 200, and a handle part 300.

[0042] The housing 100 forms the appearance of the buoyancy generating device for a vehicle according to the present invention and can be detachably provided in the vehicle. The housing 100 can be provided in the interior space or on the vehicle body of the vehicle and is exposed to the outside when a waterlogging accident occurs for the use of the occupants. The vehicle can include a rain sensor, a power outage sensor, etc. for sensing waterlogging. Usually, if the housing 100 is formed in a state of being exposed to the occupants, it may limit the use of the interior space. Therefore, the housing 100 can be configured to be stored in the vehicle usually and only be exposed when the sensor senses that the vehicle is waterlogged, so that the occupants can use it easily.

[0043] The buoyancy generating part 200 is a structure for generating buoyancy, which provides buoyancy in water during operation so that the occupants can float to the water surface. The buoyancy generating part 200 can be provided inside the housing 100. The buoyancy generating part 20 can include a tube body 210 and a gas supply machine 220.

[0044] The tube body 210 is usually arranged in the housing 100 in a folded state and can be unfolded to the outside of the housing 100 when receiving expansion gas, so as to provide buoyancy. An unfolding part such as a sewing thread that is easy to tear can be formed on the outside of the housing 100 so that the tube body 210 can break through the housing 100 and be exposed to the outside when it expands.

[0045] The gas supply machine 220 is a structure that stores expansion gas inside to provide expansion gas to the tube body 210 during operation. The expansion gas is compressed under high pressure and stored in the gas supply machine 220, so that the tube body 210 can be unfolded quickly. The gas supply machine 220 needs to be sealed to prevent the leakage of expansion gas, and in order to provide expansion gas to the tube body 210, one side of the gas supply machine can be connected to the tube body 210. The operation mode of the gas supply machine 220 can be that when the volume decreases due to an external force, the pressure of the expansion gas inside increases, so as to discharge the expansion gas to the tube body 210.

[0046] The handle part 200 is a structure provided on the housing 100 and provides a handle so that the occupants can float up from the water. The handle part 200 has a shape that is easy for the occupants to hold. When the occupants hold it with their hands in the water, the occupants can float to the water surface by the buoyancy generated by the buoyancy generating part 200. As shown in the figure, preferably, the handle part 300 is formed in a hollow shape to have a shape that is easy for the occupants to hold.

[0047] Figure 2 It is a view showing the inside of the buoyancy generating device for a vehicle according to an embodiment of the present invention. Refer to Figure 2 and the handle part 300 can include a trigger 310, a pressure transmission part 330, a deformation part 320, and an elastic body 340. A pressure transmission element 240 and a closer 230 can be formed in the buoyancy generating part 200.

[0048] The buoyancy generating device for a vehicle according to an embodiment of the present invention can be operated by a passenger gripping the handle portion 300. When the passenger grips the handle portion 300 with a hand, the gripping pressure can be transmitted to the air supply machine 220. The air supply machine 220 can be operated by the pressure and supply the expansion gas to the tube body 210, so that the tube body 210 unfolds and generates buoyancy.

[0049] The handle portion 300 can be provided with a trigger 310, and an elastomer 340 can be formed in the trigger 310. The trigger 310 can move in the direction of the pressure applied by the passenger, and can move in the vertical direction as shown. When the trigger 310 moves, the air supply machine 220 can be operated in linkage with the trigger 310. Figure 2 As shown, it moves in the vertical direction. When the trigger 310 moves, the air supply machine 220 can be operated in linkage with the trigger 310.

[0050] The handle portion 300 can further include a deformation portion 320. When the deformation portion 320 is subjected to pressure, it can be deformed in the direction of the pressure or move in the direction of the pressure.

[0051] In the case where the deformation portion 320 is deformed, when the pressure applied to the trigger 310 is received, the volume of the deformation portion 320 decreases, and the pressure corresponding to the decreased volume can be transmitted to the air supply machine 220. When the pressure is received, the volume of the air supply machine 220 decreases, and the pressure of the expansion gas inside increases, so that the gas can be discharged to the tube body 210.

[0052] In addition, the handle portion 300 can further include a pressure transmission portion 330. The pressure transmission portion 330 is connected between the deformation portion 320 and the air supply machine 220, so that the pressure generated by the deformation portion 320 can be transmitted to the air supply machine 220.

[0053] In order to effectively transmit the pressure, the pressure transmission portion 330 can be formed of a microtube with a narrow cross-sectional area. This is to use the principle that when the cross-sectional area of a fluid narrows under constant pressure, the force increases to provide strong force to the air supply machine 220. The air supply machine 220 contracts due to the strong force, and the pressure of the expansion gas inside increases, so that the expansion gas can be provided to the tube body 210. Therefore, in an emergency situation, the passenger can easily operate the air supply machine 220 by applying a small force to the trigger 310, which has the advantage of preventing safety accidents. The cross-sectional area of the microtube can be formed to be smaller than the cross-sectional area of the handle portion 300 and to be able to transmit force sufficiently.

[0054] The deformable portion 320 may be formed in the shape of a corrugated tube. One end of the deformable portion 320 may be connected to the trigger 310 and sealed, and the other end may be connected to the pressure transmission portion 330 and sealed. That is, both ends of the deformable portion 320 are sealed to the trigger 310 and the pressure transmission portion 330. The displacement of the trigger 310 caused by the sealing of the deformable portion 320 is fully reflected as the deformation amount of the deformable portion 320, so that the pressure applied to the trigger 310 can be transmitted to the air supply machine 220 through the pressure transmission portion 330. That is, since the pressure is transmitted without loss, the occupant only needs to apply a small pressure to operate the air supply machine 220, so it can be easily used in an emergency.

[0055] In addition, the handle portion 300 may further include a closure 230. The closure 230 is disposed at a position connecting the air supply machine 220 and the tube body 210, and opens when receiving a pressure exceeding a specified critical pressure, so that the expanded gas can be discharged to the tube body 210. The closure 230 may be a film that opens when receiving a pressure exceeding a specified critical pressure. When the air supply machine 220 operates to increase the pressure of the expanded gas, the discharge pressure of the expanded gas exceeds the critical pressure of the closure 230, causing the closure 230 to open. The expanded gas flows into the tube body 210 through the closure 230 and expands the tube body, so that buoyancy can be provided to the occupant.

[0056] In addition, the handle portion 300 may further include a pressure transmission element 240. The pressure transmission element 240 may perform the function of transmitting the pressure applied by the occupant to the handle portion 300 to the air supply machine 220. The pressure transmission element 240 may be disposed outside the air supply machine 220 and is usually used to seal the air supply machine 220. When the occupant tightly holds the handle portion 300, the pressure applied by the occupant is transmitted to the pressure transmission element 240. The pressure transmission element 240 may receive the pressure and increase the internal pressure of the air supply machine 220 by pressing the air supply machine 220 from the outside, so that the closure 230 is opened and expanded gas is provided to the tube body 210. Alternatively, the pressure transmission element 240 may be formed of a flexible material and connected to the air supply machine 220, so that the pressure applied by the occupant can flow into the interior of the air supply machine 220. When the pressure transmission element 240 is formed of a flexible plastic material, it deforms toward the air supply machine 220 according to the pressure applied by the occupant and increases the internal pressure of the air supply machine 220. The internal pressure of the air supply machine 220 is increased through the pressure transmission element 240, and when the internal pressure exceeds the critical pressure of the closure 230, the closure 230 is opened, so that buoyancy can be generated.

[0057] In addition, the buoyancy generation device for a vehicle according to an embodiment of the present invention may further include a connection line. One end of the connection line is connected to the vehicle body, and is disconnected from the housing 100 when the tube body 210 is deployed. The connection line 400 can connect the housing 100 to the vehicle to prevent the buoyancy generation device from being lost. When a waterlogging condition occurs, the connection line 400 is separated for use by the occupants. If the buoyancy generation device is set in an exposed state, it may be misoperated due to unexpected external forces, resulting in the risk that the buoyancy generation device does not operate in a situation where the buoyancy generation device is needed. Therefore, the connection line 400 can enable the buoyancy generation device to be normally installed in the vehicle and only be exposed to the occupants in a situation where the buoyancy generation device is needed.

[0058] In addition, the connection line 400 can be connected to the handle part 300, so that when the occupant tightly holds the handle part 300, the connection between the connection line 400 and the housing 100 is released by the pressure. Therefore, when the occupant tightly holds the handle part 300 in an emergency, the housing 100 is separated from the vehicle and can float to the water surface. The handle part 300 and the connection line 400 are physically connected, so that they can also be structurally connected or separated. For example, when the occupant grabs the handle part 300, the pin of the handle part 300 can move to separate the connection line 400. In addition, the handle part 300 and the connection line 400 can also be electrically connected, so that they can be connected or separated according to an electrical signal. For example, a solenoid type locking device can be used.

[0059] In addition, a tear line can be provided on the outer side surface of the housing 100, which can expose the tube body 210 to the outside after expansion. Like a weak sewing thread, when the internal part of the tear line receives a force above a specified level, it is easily torn, so that the tube body 210 can easily penetrate the housing 100 and expand to the outside.

[0060] In addition, although not shown in the drawings, the housing 100 may further include a lighting module. The lighting module may include a light-emitting device, so as to provide a visual signal to the occupants by emitting light in the dark. When a waterlogging accident occurs on a cloudy day or at night, there may be a dangerous situation where it is difficult for the occupants to find the installation position of the buoyancy generation device according to an embodiment of the present invention. Therefore, the occupants can easily master the installation position of the buoyancy generation device through the lighting module, thus having the advantage of preventing safety accidents. In addition, the lighting module can also be electrically connected to the above-mentioned sensor for sensing waterlogging to emit light when waterlogging is sensed. The lighting module can automatically emit light in a waterlogging condition, so that it is easy for the occupants to use.

[0061] The lighting module can be charged through the connection line 400. The lighting module can have a battery that provides power to the lighting module, and the battery is charged by connecting to the connection line 400.

[0062] Figure 3 FIG. Figure 3 is a view showing a state in which a buoyancy generating device for a vehicle according to an embodiment of the present invention is exposed to the vehicle. Figure 4 FIG. Figure 4 is a view showing an operating state of a buoyancy generating device for a vehicle according to an embodiment of the present invention. Figure 5 FIG. Figure 5 is a view showing a usage state of a buoyancy generating device for a vehicle according to an embodiment of the present invention.

[0063] Refer to Figures 3 to 5 FIGs. Figure 3 to Figure 5 , and the usage of a buoyancy generating device for a vehicle according to an embodiment of the present invention will be described as follows.

[0064] As Figure 3 shown in FIG. Figure 3 , a buoyancy generating device according to an embodiment of the present invention is usually installed in a vehicle and is exposed in the event of vehicle flooding to facilitate use by an occupant. At this time, in the case of having a connection line 400, the buoyancy generating device is exposed in a state where one end is connected to the vehicle through the connection line 400.

[0065] Refer to Figure 4 FIG. Figure 4 . When an occupant grabs the handle portion 300 with a hand and tightly holds it, the connection line 400 can be separated. By separating the connection line 400, the housing 100 is separated from the vehicle, and by tightly holding, the buoyancy generating portion 200 operates according to the above principle, and the tube body 210 is deployed. When the expansion gas flows into the tube body 210 and the tube body 210 is deployed, buoyancy can be generated. Therefore, as Figure 5 shown in FIG. Figure 5 , the occupant grabs the handle portion 300 with a hand and floats to the water surface together with the tube body 210. Therefore, in the event of a flooding accident, a personal accident of the occupant can be prevented.

[0066] As described above, although specific embodiments of the present invention have been described with reference to the drawings, it is obvious to those of ordinary skill in the art that various improvements and changes can be made without departing from the technical idea of the present invention provided in the claims.
