Description

Technical Field

[0001] The present invention relates to the field of water-falling flotation-aiding equipment, in particular to an automatic inflatable flotation-aiding equipment for water-falling. Background Art

[0002] With technological advancements, drones, as a new technology, are gradually gaining recognition and widespread adoption due to their unique advantages. However, with the widespread use of drones, flight safety has also become a growing concern, and various equipment to ensure drone flight safety has rapidly developed. Among these, drone floats are particularly useful for recovering drones that have fallen into the water due to malfunctions.

[0003] The original drone floats after falling into the water. After the drone falls into the water, the sponge absorbs water and expands, squeezing the electronics at the front end to connect the electronics. There is a wire at the front end of the electronics. After power is turned on, the head ignites and detonates the cotton wool, pushing the firing pin at the front to pierce the gas cylinder. The gas in the gas cylinder quickly flows into the airbag to inflate the airbag. As the airbag expands, the drone gradually floats to the water surface.

[0004] However, most of the automatically inflating life-saving airbags in the existing technology adopt an electronic trigger structure. The electronic components need to be sealed during production. Failure to seal will cause the risk of water ingress. At the same time, the internal structure of the equipment is relatively complex and the triggering link is relatively complicated, which makes the actual weight of the product larger, increases the load of the drone during normal flight, and puts a certain burden on the drone's flight. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an automatic inflatable flotation device for falling into water to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic inflatable flotation aid device for falling into water, comprising a lower shell, a card block, a card interface, a strap, a drone leg and an upper shell, the lower shell and the upper shell ends are respectively provided with a first water permeable port and a second water permeable port, an expansion sponge is installed in the lower shell, and a gas cylinder that conflicts with the expansion sponge is movably installed in the lower shell, a fixing frame corresponding to the gas cylinder is installed in the lower shell, and an air guide seat corresponding to the gas cylinder is provided at the other end of the lower shell, an air guide hole corresponding to the gas cylinder is opened in the air guide seat, and the air nozzle at the end of the gas cylinder conflicts with the inner end of the air guide hole, an air bag is detachably installed on the top of the air guide seat, and the air nozzle at the end of the air bag is connected to the air guide hole.

[0007] By adopting this technical solution, when the device falls into water, the expansion sponge expands and pushes the gas cylinder toward the air guide seat. The guide hole squeezes the gas nozzle of the gas cylinder, releasing gas from inside. The air guide hole, delivery hole, and guide hole all work together to inflate the airbag. This product is a purely mechanical design that can be stored for a long time without maintenance. It has higher reliability, lower cost, and is extremely lightweight and compact, making it suitable for flight platforms.

[0008] The present invention is further configured such that a plurality of through openings are formed through the bottom surface of the lower shell, and the through openings close to the interior of the lower shell are open.

[0009] By adopting the above technical solution, water in the lower shell can flow through the opening, thereby effectively reducing the resistance when the airbag drives the lower shell to rise.

[0010] The present invention is further configured such that the first water permeable openings and the second water permeable openings are provided in multiple groups at equal angles at the ends of the lower shell and the upper shell, respectively, and the opening positions of the first water permeable openings and the second water permeable openings correspond to the positions of the expansion sponges.

[0011] By adopting the above technical solution, water can enter the lower shell through multiple groups of first water permeable openings and second water permeable openings at the same time, thereby achieving the expansion of the expandable sponge.

[0012] The present invention is further configured such that two gas cylinders are symmetrically installed in the lower shell, and the gas nozzles at the ends of the gas cylinders are press-type gas nozzles.

[0013] By adopting the above technical solution, when the gas cylinder slides towards the gas guide seat, the gas nozzle at the end thereof will be squeezed, so that the gas cylinder will automatically open and release gas as the product falls into water.

[0014] The present invention is further configured such that a support frame corresponding to the air guide seat is installed in the lower shell, and multiple groups of corresponding bolt holes are provided on the support frame and the air guide seat, and the support frame and the air guide seat are connected by bolts.

[0015] By adopting the above technical solution, the support frame will support the air guide seat, thereby ensuring the fixity of the position of the air guide seat.

[0016] The present invention is further configured such that a delivery hole corresponding to the airbag is provided in the air guide seat, the delivery hole is designed as a threaded hole, and the airbag is connected to the delivery hole by a thread.

[0017] By adopting the above technical solution, the connection between the airbag and the air guide seat is fixed, and the airbag can be easily disassembled and maintained.

[0018] The gas guide seat is internally provided with two groups of guide holes corresponding to the gas guide holes, and the gas guide holes are communicated with the conveying holes through the guide holes.

[0019] By adopting the above technical scheme, the gases emitted by the two gas cylinders can be synchronously introduced into the conveying holes, so that the gases can be introduced into the air bag.

[0020] The diameter of the guide hole is smaller than that of the gas guide hole, and the diameter of the guide hole is the same as the inner diameter of the gas nozzle at the end of the gas cylinder.

[0021] By adopting the above technical scheme, the gas nozzle at the end of the gas cylinder can be in contact with the connection part of the guide hole and the gas guide hole, and the gas nozzle at the end of the gas cylinder will not enter the guide hole.

[0022] The guide hole and the conveying hole are provided with sealing elements corresponding to the gas nozzle at the end of the gas cylinder, and the conveying hole is provided with a sealing element at the connection part of the air bag.

[0023] By adopting the above technical scheme, the leakage of a large amount of gas is effectively prevented, and the inflation of the air bag is affected.

[0024] In summary, the present application mainly has the following beneficial effects:

[0025] The present application is provided with an inflatable sponge, a gas guide seat, a gas guide hole, a conveying hole and a guide hole. Under the action of the inflatable sponge, when the equipment falls into water, the inflatable sponge will expand and push the gas cylinder to the gas guide seat. Under the action of the guide hole, the gas nozzle of the gas cylinder is extruded, so that the gas inside is released. Under the action of the gas guide hole, the conveying hole and the guide hole, the air bag is inflated.

DETAILED DESCRIPTION

[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] An automatic inflatable floatation aid for falling into water, as shown in Figures 1-6, includes a lower shell 1, a clamping block 101, a card interface 1011, a strap 102, a drone leg 1021 and an upper shell 2.

[0036] Specifically, the ends of the lower shell 1 and the upper shell 2 are respectively provided with a first water permeable port 3 and a second water permeable port 4 to ensure that water can enter the lower shell 1 and the upper shell 2 through the first water permeable port 3 and the second water permeable port 4, and an expansion sponge 5 is installed in the lower shell 1. When a large amount of water is absorbed into the expansion sponge 5, the expansion sponge 5 will begin to expand, and a gas cylinder 6 that conflicts with the expansion sponge 5 is movably installed in the lower shell 1, so that when the expansion sponge 5 expands, the gas cylinder 6 will be pressed and slide toward the air guide seat 8, and a fixing frame 7 corresponding to the gas cylinder 6 is installed in the lower shell 1. The fixing frame 7 will cooperate with the air guide seat 8 to limit the position of the gas cylinder 6, and an air guide seat 8 corresponding to the gas cylinder 6 is provided at the other end of the lower shell 1, and an air guide hole 9 corresponding to the gas cylinder 6 is opened in the air guide seat 8, and the air nozzle at the end of the gas cylinder 6 conflicts with the inner end of the air guide hole 9, and the gas cylinder 6 There are two symmetrically installed in the lower shell 1, and the gas nozzle at the end of the gas cylinder 6 is a press-type gas nozzle, so that when the gas cylinder 6 slides toward the gas guide seat 8, the gas nozzle at the end will be squeezed, thereby prompting the gas nozzle to open, so that the gas inside the gas cylinder 6 quickly enters the gas guide hole 9, and the air bag 12 is detachably installed on the top of the gas guide seat 8, and the gas nozzle at the end of the air bag 12 is connected to the gas guide hole 9, so that the gas in the gas guide hole 9 will enter the air bag 12, so that the air bag 12 is quickly inflated. In the process of opening the air bag 12, the upper shell 2 will be pushed open. After the air bag 12 is fully inflated, it will have buoyancy, which makes it convenient for staff to rescue drones equipped with this equipment or other equipment that needs to be automatically inflated when it falls into water. In addition, this product is a purely mechanical design, can be stored for a long time without maintenance, has higher reliability, lower cost, and is extremely small in weight and volume, making it suitable for flight platforms.

[0037] See also Figure 5 In the above embodiment, multiple groups of through openings 103 are formed through the bottom surface of the lower shell 1, and the through openings 103 close to the inside of the lower shell 1 are open, so that when the airbag 12 drives the lower shell 1 to rise, the water in the lower shell 1 can flow through the through openings 103, thereby effectively reducing the resistance when the airbag 12 drives the lower shell 1 to rise.

[0038] See also Figure 1-2 and Figure 5 In the above embodiment, multiple groups of first water permeable openings 3 and second water permeable openings 4 are respectively provided at equal angles at the ends of the lower shell 1 and the upper shell 2, so that water can simultaneously enter the lower shell 1 through multiple groups of first water permeable openings 3 and second water permeable openings 4. At the same time, because the positions of the first water permeable openings 3 and the second water permeable openings 4 correspond to the positions of the expandable sponge 5, the expandable sponge 5 will come into contact with a large amount of water, thereby achieving the expansion of the expandable sponge 5.

[0039] See also Figure 5In the above embodiment, a support frame 81 corresponding to the air guide seat 8 is installed in the lower shell 1. The support frame 81 supports the air guide seat 8, thereby ensuring the fixed position of the air guide seat 8, and multiple groups of corresponding bolt holes are provided on the support frame 81 and the air guide seat 8, and the support frame 81 and the air guide seat 8 are connected by bolts, so that the air guide seat 8 can be removed from the support frame 81 for maintenance.

[0040] See also Figure 3-4 In the above embodiment, a delivery hole 10 corresponding to the airbag 12 is opened in the air guide seat 8, and the delivery hole 10 is a threaded hole design, and the airbag 12 is connected to the delivery hole 10 by a thread, so that the connection between the airbag 12 and the air guide seat 8 is fixed, and the airbag 12 is convenient for disassembly and maintenance. Two groups of guide holes 11 corresponding to the air guide holes 9 are opened in the air guide seat 8, so that the gas released by the two groups of gas cylinders 6 can enter the corresponding guide holes 11, and the air guide holes 9 are connected to the delivery hole 10 through the guide holes 11. Under the guidance of the guide holes 11, the gas emitted by the two gas cylinders 6 will enter the delivery hole 10 synchronously, thereby ensuring that the gas will enter the airbag 12.

[0041] See also Figure 4 In the above embodiment, the diameter of the guide hole 11 is smaller than the diameter of the gas guide hole 9, thereby ensuring that the gas nozzle at the end of the gas cylinder 6 will conflict with the connection between the guide hole 11 and the gas guide hole 9, while at the same time ensuring that the gas nozzle at the end of the gas cylinder 6 will not enter the guide hole 11, and the diameter of the guide hole 11 is the same as the inner diameter of the gas nozzle at the end of the gas cylinder 6, so that when the gas nozzle at the end of the gas cylinder 6 is pressurized and opened, the gas can smoothly enter the guide hole 11.

[0042] See also Figure 3-4 In the above embodiment, a sealing member corresponding to the gas nozzle at the end of the gas cylinder 6 is provided at the connecting position between the guide hole 11 and the delivery hole 10, which effectively increases the sealing between the connecting position between the guide hole 11 and the delivery hole 10 and the gas nozzle at the end of the gas cylinder 6, thereby preventing a large amount of gas leakage when the gas cylinder 6 is deflated. In addition, a sealing member is provided at the connection between the delivery hole 10 and the airbag 12, thereby improving the sealing of the connection between the delivery hole 10 and the airbag 12, further preventing a large amount of gas leakage from affecting the inflation of the airbag 12.

[0043] The working principle of the present invention is as follows: when a drone equipped with this device or other device that needs to be automatically inflated when it falls into water, water will first enter the lower shell 1 and the upper shell 2 through the first water permeable port 3 and the second water permeable port 4, causing a large amount of water to be absorbed into the expansion sponge 5, thereby causing the expansion sponge 5 to begin to expand, and then the gas cylinder 6 is pressed to slide toward the air guide seat 8, because the air nozzle at its end conflicts with the air guide hole 9 and the end of the guide hole 11, thereby causing the air nozzle at the end of the gas cylinder 6 to open. At this time, the gas in the gas cylinder 6 will be quickly released, causing the airbag 12 to be quickly inflated. In the process of the airbag 12 opening, the upper shell 2 will be pushed open. After the airbag 12 is fully inflated, it will have buoyancy, thereby making it convenient for staff to rescue the drone equipped with this device or other device that needs to be automatically inflated when it falls into water.

[0044] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
