[0024] Please refer to Figures 1-4 The embodiment provides a multifunctional warning device, which comprises a supporting framework 100, a waterproof air bag 200, a walking mechanism 300 and an alarm mechanism 400; the supporting framework 100 is connected with the waterproof air bag 200, the waterproof air bag 200 has an inflation state and a folding state which are switched with each other, when in the inflation state, the waterproof air bag 200 is in a tetrahedron structure; when in the folding state, the waterproof air bag 200 is in a planar triangle; the walking mechanism 300 and the alarm mechanism 400 are both installed on the supporting framework 100, the walking mechanism 300 is used for walking on the ground; the alarm mechanism 400 is used for sending a sound alarm signal or / and a light alarm signal.

[0025] As described above, the multifunctional warning device provided in this embodiment is used as follows: In its initial state, the waterproof airbag 200 is uninflated and folded, roughly triangular in shape, compact and small in size, making it easy to store in the vehicle's trunk. In an emergency, the waterproof airbag 200 can be inflated, transforming into a tetrahedral structure. When used on roads, it can be automatically positioned by the walking mechanism 300, eliminating the need for manual placement, making it easy to place and highly safe. When used in water, the inflated and waterproof airbag 200 provides buoyancy, allowing it to float on the surface and aid in rescue efforts. During operation, the multi-functional warning device activates the alarm mechanism 400, providing audible and visual alarm information. Furthermore, the tetrahedral structure of the waterproof airbag 200 provides a three-dimensional warning effect, making it easy to observe and providing a strong alert.

[0026] It should be understood that this multi-functional warning device can be used in conjunction with vehicles, ships, or aircraft, and has a wide range of applications.

[0027] The following embodiments illustrate the details of the multifunctional warning device of this application by way of example.

[0028] Please refer to Figures 1-4 In this embodiment, optionally, the multi-functional warning device includes a support frame 100, a waterproof airbag 200, a walking mechanism 300, an alarm mechanism 400, and a flight mechanism 500. The waterproof airbag 200, the walking mechanism 300, the alarm mechanism 400, and the flight mechanism 500 can all be connected to the support frame 100 to form a single module, which is compact, small in size, and easy to store and use.

[0029] Initially, the waterproof airbag 200 is uninflated and folded, roughly triangular in shape. In emergencies, the airbag 200 inflates, transforming into a tetrahedral structure, increasing its volume, visible area, and viewing angle, making it easier to observe and providing a better warning. When placed on a road, the walking mechanism 300 can automatically position the warning device at a set distance. When placed in water, it floats on the surface using buoyancy; in complex terrain, the flying mechanism 500 can lift the entire device off the ground, providing a warning from the air. The warning device is flexible in use and suitable for various scenarios.

[0030] In this embodiment, optionally, the support frame 100 can be a tripod, which can be fixed to the surface of the waterproof airbag 200 by means of adhesive, screws, anchors, etc. The support frame 100 can be a plastic frame, which is lightweight and easy to move; at the same time, the plastic frame can be a hollow frame, which can provide a certain buoyancy and float better on the water surface.

[0031] It should be understood that in some scenarios, when a vehicle is trapped in water, the owner can operate the button inside the car to open the trunk. The waterproof airbag 200 can be inflated by the air pump installed in the vehicle. The waterproof airbag 200 has a certain buoyancy and can float on the water surface. With the trunk open, it can leave the trunk, making it easier to be found and facilitating rescue work.

[0032] Please refer to Figures 2-3 Optionally, the waterproof airbag 200 is equipped with a one-way inflation valve 210. One end of the one-way inflation valve 210 is connected to a hose, and the other end is used to connect to an air pump. To improve stability, the one-way inflation valve 210 can be fixed to the support frame 100. The air pump can be integrated into the vehicle, and the air pump can be separately configured with a second power supply and controller. When an accident occurs, the air pump can be manually or automatically activated. For example, a collision sensor can be installed in the vehicle. When the collision sensor is triggered, the signal from the collision sensor is transmitted to the controller, and the controller automatically starts the air pump to inflate the waterproof airbag 200 through the hose.

[0033] Optionally, the one-way inflation valve 210 is equipped with a connection port, and a hose is fitted over the connection port. The hose and the connection port are detachably connected via a quick-release clip. With this design, in the event of a traffic accident on the road, the air pump inflates the waterproof airbag 200. The vehicle owner can actively detach the hose from the one-way inflation valve 210, remove the waterproof airbag 200 from the vehicle, place it on the ground, and use the walking mechanism 300 to move the waterproof airbag 200 to a designated location. In the event of a traffic accident in a water environment, the hose serves not only as an air delivery pipe but also as a rope connecting to the vehicle. In this case, the quick-release clip keeps the hose connected to the one-way inflation valve 210. After inflation, the waterproof airbag 200 remains connected to the vehicle through the hose, preventing it from being swept away from the vehicle and facilitating positioning for rescue personnel.

[0034] In this embodiment, optionally, the alarm mechanism 400 includes a first power supply 410, an alarm 420, and an automatic start unit 430. Both the first power supply 410 and the alarm 420 are connected to the support frame 100. The first power supply 410 and the alarm 420 are electrically connected, and can be electrically connected via a second power line to form a circuit loop. When the first power supply 410 is activated, it can provide power to the alarm 420. The automatic start unit 430 is connected to a one-way inflation valve 210. The automatic start unit 430 is activated when fluid enters the waterproof airbag 200 from the one-way inflation valve 210. After activation, the automatic start unit 430 turns on the first power supply 410. That is, in the initial state, the waterproof airbag 200 is not inflated, the automatic start unit 430 is not activated, and the first power supply 410 is disconnected. When the warning device is needed, the air pump inflates the waterproof airbag 200 through a hose. Airflow enters the waterproof airbag 200 through the one-way inflation valve 210, activating the automatic start unit 430 and automatically turning on the first power supply 410. The alarm 420 then operates, providing an alarm signal. In this embodiment, the alarm 420 can be automatically activated, making it convenient and reliable to use.

[0035] Optionally, the start switch of the first power supply 410 includes a first conductive sheet 411 and a second conductive sheet 412 arranged at intervals. The start switch is installed on the circuit circuit. In the initial state, because the first conductive sheet 411 and the second conductive sheet 412 are arranged at intervals, the circuit circuit is in an open circuit state, and the alarm 420 is in a power-off state and will not operate. When the air pump inflates the waterproof airbag 200, the automatic start unit 430 is triggered, which can connect the first conductive sheet 411 and the second conductive sheet 412, thereby making the circuit conductive.

[0036] Please refer to Figures 2-3Optionally, the automatic start unit 430 includes a trigger plate 431, a rotating shaft 432, a conductive rod 433, a waterproof box 434, a waterproof elastic layer 435, a baffle 436, a first torsion spring 437, a second torsion spring 438, and a spring 439. The trigger plate 431 is rotatably connected to the one-way inflation valve 210 via the rotating shaft 432. The first torsion spring 437 is sleeved outside the rotating shaft 432 and provides the trigger plate 431 with a spring force for rotation in a first direction 001. One side of the trigger plate 431 closes the air outlet 211 of the one-way inflation valve 210, and the other side of the trigger plate 431 is spaced from the air outlet 211. The waterproof box 434 has an open side and is connected to the support frame 100. The waterproof elastic layer 435 closes the open side. The conductive rod 433 penetrates and is sealed to the waterproof elastic layer 435. The conductive rod 433 is slidably connected to the waterproof box 434. One end of the conductive rod 433, located outside the waterproof elastic layer 435, is on the rotation path of the trigger plate 431 on the other side. Simultaneously, the conductive rod 433 is connected to a spring 439, which in turn is connected to the waterproof box 434. The spring 439 is located inside the waterproof box 434 and causes the conductive rod 433 to tend to move away from the first conductive piece 411 and the second conductive piece 412. Both the first conductive piece 411 and the second conductive piece 412 are located inside the waterproof box 434, providing good waterproof performance and preventing short circuits due to water contact. The baffle 436 is rotatably connected to the one-way inflation valve 210. The baffle 436 is connected to the one-way inflation valve 210 via a second torsion spring 438. The second torsion spring 438 enables the baffle 436 to have a tendency to rotate in the first direction 001, and the elastic force of the second torsion spring 438 is greater than that of the first torsion spring 437. Furthermore, the trigger plate 431 is located on the side of the baffle 436 near the air outlet 211, thereby pressing the trigger plate 431 against the air outlet 211 of the one-way inflation valve 210 via the baffle 436. When the air pump inflates the waterproof airbag 200, the trigger plate 431 can rotate along the first direction 001 under the action of the airflow and push the baffle 436 to rotate along the second direction 002 opposite to the first direction 001. After the trigger plate 431 rotates a certain angle, the trigger plate 431 can pass over the baffle 436 and contact the conductive rod 433, pushing the conductive rod 433 to insert between the first conductive sheet 411 and the second conductive sheet 412, thereby conducting the first power supply 410 and realizing the automatic start of the alarm 420.

[0037] Since the trigger plate 431 passes the baffle 436, the first torsion spring 437 applies a spring force to the trigger plate 431 to rotate in the first direction 001, so that the trigger plate 431 can push the conductive rod 433, overcome the spring force of the spring 439 and keep the conductive rod 433 in the position between the first conductive piece 411 and the second conductive piece 412, so that the conduction effect is good.

[0038] It should be understood that after use, the waterproof airbag 200 deflates. Then, the baffle 436 can be manually operated to rotate it first along the second direction 002, and then the trigger plate 431 can be operated to rotate it along the second direction 002. The trigger plate 431 will then rotate again to the side of the baffle 436 near the air outlet 211, using the baffle 436 to restrict the rotation of the trigger plate 431 along the first direction 001. Under the action of the spring 439, the conductive rod 433 separates from the first conductive sheet 411 and the second conductive sheet 412, and the first power supply 410 is disconnected.

[0039] In this embodiment, optionally, the walking mechanism 300 includes a second power supply and a hub motor, both of which are mounted on the support frame 100. The second power supply is electrically connected to the hub motor; the hub motor is used for walking on the ground. The number of walking mechanisms 300 can be designed as needed; for example, three can be set, which provides high stability.

[0040] It should be understood that the walking mechanism 300 may also include a remote controller, which is electrically connected to the hub motor and used to adjust the working status of the hub motor. This provides convenient and flexible operation.

[0041] Optionally, in some embodiments, the flight mechanism 500 may include a motor and a propeller. Multiple flight mechanisms 500 may be mounted on the support frame 100, and the cooperation of multiple flight mechanisms 500 can propel the entire warning device off the ground. Obviously, the flight mechanism 500 can also be controlled by a remote controller.

[0042] It should be understood that, in order to adapt to use in aquatic environments, many electrical components of the multi-functional warning device can be waterproofed. Furthermore, the alarm 420 may include a speaker and / or a light fixture, the light fixture of which can be installed inside a waterproof airbag 200, which is translucent to improve visibility.

[0043] The multifunctional warning device provided in this embodiment can adapt to various environments such as land, water, and air, making it widely applicable and flexible in use. During use, it presents a three-dimensional, multi-faceted display with a wide range of visibility, facilitating observation and identification, and providing excellent alerting effects.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
