[0039] The related art adopts the way of manually releasing the air bag and inflating the high-pressure gas cylinder, which on the one hand leads to a large weight and volume of the entire air bag system, is not conducive to the lightweight of the aircraft, and the triggering time is slow, which cannot meet the use demand of the forced landing of the aircraft in low altitude flight. In view of the above problems, the air bag assembly provided in the embodiments of the application can simplify the overall weight of the air bag assembly, which is conducive to the lightweight of the aircraft, and can meet the forced landing demand of the aircraft in low altitude flight.

[0040] The technical solutions of the embodiments of the application are described in detail below with reference to the drawings.

[0041] Figure 1 is a structural schematic diagram of the airbag assembly shown in the embodiments of the present application; Figure 2 is a sectional view of the airbag assembly shown in the embodiments of the present application; Figure 3 is an exploded view of the airbag assembly shown in the embodiments of the present application.

[0042] Please see Figures 1-3 , the present application provides an airbag assembly 100, the airbag assembly 100 includes a shell 140, an airbag 110, an initiating component 120 and at least one inflation component 130; the shell 140 forms a containing space, the airbag 110 is housed in the containing space when in a collapsed state, the airbag 110 is provided with a first air inlet 111 and a second air inlet 112; the initiating component 120 is provided corresponding to the first air inlet 111, the initiating component 120 is used to charge the airbag 110 with gas through the first air inlet 111, so that the airbag 110 is ejected from the shell 140; the inflation component 130 is provided corresponding to the second air inlet 112, the inflation component 130 is used to charge the airbag 110 with gas through the second air inlet 112 after the airbag 110 is ejected, so that the airbag 110 is deployed.

[0043] The airbag assembly 100 provided by the present application combines the initiating component 120, the inflation component 130 and the airbag 110, after the initiating component 120 is triggered, high-pressure gas can be charged into the airbag 110, so that the airbag 110 is ejected from the shell 140, at the same time, the inflation component 130 is started to continuously inflate the airbag 110 until the airbag 110 is completely deployed. Compared with the structure of related art which uses manual triggering and high-pressure gas cylinder inflation, the present application avoids using manual triggering mechanism and high-pressure gas cylinder, which can simplify the overall weight of the airbag assembly 100 and is beneficial to the lightweight of the aircraft.

[0044] Moreover, after the inflation component 130 is triggered, the ejected airbag 110 can be quickly inflated, so that the airbag 110 is rapidly inflated and deployed in a short time, which can be applied to the forced landing demand of the aircraft when flying at low altitude.

[0045] In the present application, the initiating component 120 is an electronic component which can receive a trigger signal, can be detonated and can generate high-temperature and high-pressure gas after detonation. In some specific embodiments, the initiating component 120 includes a detonating head, a charge and an electronic circuit and the like. When the initiating component 120 receives a trigger signal, an electric spark plug in the detonating head will generate an electric spark, ignite the charge, and the charge will rapidly explode to generate high-temperature and high-pressure gas. These gases enter the airbag 110 in the shell 140 through the first air inlet 111, so that the airbag 110 is rapidly inflated and ejected from the shell 140.

[0046] Since the high-temperature and high-pressure gas generated by the initiating component 120 is not persistent, it is difficult to make the air bag 110 fully expand. Therefore, the application also provides the inflating component 130. After the air bag 110 is ejected, the inflating component 130 is started synchronously to inflate the air bag 110, so that the air bag is fully inflated and expanded.

[0047] In some embodiments, the inflating component 130 is a fan, for example, an axial fan. The fan is provided with an air inlet end and an air outlet end. The air inlet end faces away from the air bag 110, and the air outlet end is connected in communication with the second air inlet part 112. After the fan is started, the air outside is continuously filled into the air bag 110 through the second air inlet part 112, so that the air bag 110 is inflated and expanded.

[0048] In some embodiments, the shell 140 is fixed to the middle region of the air bag 110 after the air bag 110 is expanded. The air bag 110 is expanded on the side of the shell 140 away from the inflating component 130. The thickness direction of the expansion is parallel to the inflating direction of the fan, and the width direction of the expansion is perpendicular to the inflating direction of the fan.

[0049] In the embodiment, the air bag 110 is substantially rectangular after being fully expanded, but is not limited to a rectangle, and can also be circular, elliptical or other irregular shapes. The air bag 110 has a middle part and a hollow annular part surrounding the outer periphery of the middle part in the expanded state. The height of the annular part is higher than that of the middle part, or the middle part is concave downward. The shell 140 is mounted on the middle part of the air bag 110.

[0050] In some embodiments, the air bag 110 can be provided with an exhaust hole. The inflating amount of the inflating component 130 is greater than the exhaust amount of the exhaust hole. During the inflating process of the inflating component 130, the air bag 110 can simultaneously exhaust. After being set in this way, when the gas pressure in the air bag 110 increases to a predetermined threshold or the effective load reaches a predetermined overload, the inflating amount of the fan per unit time is equal to the exhaust amount of the exhaust hole per unit time. In this way, when the fan continuously runs, the gas pressure in the air bag 110 is stably controlled at a preset level, and the air bag 110 is not likely to be inflated and exploded.

[0051] In some embodiments, according to the actual use scene, the air bag 110 can be made of a material with air tightness, or the air bag 110 can be made of a material with air permeability. In some embodiments, when the air bag 110 is used for floating on the water surface, the exhaust hole can not be provided, and the air bag 110 is made of a material with air tightness.

[0052] In some embodiments, when the air bag 110 is used for land cushioning, the air bag 110 can be provided with exhaust holes or made of a material with air permeability. Specifically, the exhaust holes can be provided with a valve assembly that closes when impacted, and the air bag 110 first remains closed to store and absorb energy by compression. When the air pressure in the bag increases to a predetermined threshold or the payload reaches a predetermined overload, the valve assembly of the exhaust port opens, and the gas in the bag leaks out through the exhaust port to dissipate energy.

[0053] In some embodiments, the second air inlet portion 112 can also be provided with an adjusting valve to control the inflation flow of the inflation component 130, so that the air pressure change in the air bag 110 during the cushioning process can be stably controlled at a preset level.

[0054] In some embodiments, the air outlet pressure of the fan is less than the air pressure of the air bag 110 after being filled. When the air bag 110 is filled, i.e., the air pressure in the air bag 110 increases to a predetermined threshold or the payload reaches a predetermined overload, the fan cannot continue to fill the air bag 110 with gas at this time, so that the air pressure change in the air bag 110 is stably controlled at a preset level. After such a setting, the air bag 110 will not be overfilled, and there is no need to set a component or structure for controlling the inflation amount, so that the air bag assembly 100 of the present application is more simplified in structure.

[0055] In some embodiments, the shell 140 is fixedly connected with the air bag 110, and the initiating component 120 and at least one inflation component 130 are fixedly installed in the shell 140. When the air bag 110 is in a contracted state and is accommodated in the shell 140, the shell 140 can protect the air bag 110 from being damaged.

[0056] Referring to Figure 3 In some embodiments, the shell 140 is provided with an ejection portion for the air bag 110 to pop out, and the ejection portion can be an opening or a hole. The initiating component 120 and the inflation component 130 are installed on the side of the shell 140 away from the ejection portion. The shell 140 is provided with a first mounting portion 141 and a second mounting portion 142. The initiating component 120 is installed on the first mounting portion 141, and the inflation component 130 is installed on the second mounting portion 142.

[0057] The shell 140 is generally flat and fits the air bag 110 after being expanded. The shell 140 includes a top portion and a bottom portion. The ejection portion is provided on the bottom portion, and the initiating component 120 and the inflation component 130 are installed on the top portion. When the air bag 110 is filled with high-temperature and high-pressure gas by the initiating component 120, it can quickly pop out from the ejection portion on the bottom portion, and at the same time, it can be continuously inflated by the inflation component 130. Finally, the air bag 110 expands and unfolds at the outer periphery of the bottom portion of the shell 140.

[0058] In some embodiments, the shell 140 is provided with a plurality of second mounting portions 142, the inflating component 130 is provided with a plurality of inflating components 130, the air bag 110 is provided with a plurality of second air inlets 112, the plurality of inflating components 130 are respectively mounted on the plurality of second mounting portions 142 and are connected to the plurality of second air inlets 112 in one-to-one correspondence; wherein the first mounting portion 141 is arranged at the middle portion of the air bag 110, and the plurality of second mounting portions 142 are arranged around the first mounting portion 141. In this way, the gas generated by the initiating component 120 at the middle portion can uniformly enter each position of the air bag 110, so that the air bag 110 uniformly expands in each direction. In addition, the plurality of inflating components 130 simultaneously inflate the air bag 110 at multiple positions, so that the inflation speed is fast, and the expansion speed of each position of the air bag 110 is more uniform.

[0059] With reference to Figure 3 In some embodiments, the shell 140 is provided with four second mounting portions, the inflating component 130 is provided with four inflating components 130, the air bag 110 is provided with four second air inlets 112, the four inflating components 130 are respectively mounted on the four second mounting portions, and are connected to the four second air inlets 112 in one-to-one correspondence; wherein the four second mounting portions are arranged at four vertices of a virtual quadrilateral, and the first mounting portion 141 is arranged at the center of the virtual quadrilateral. Specifically, the virtual quadrilateral is arranged at the middle portion of the shell 140, and the virtual quadrilateral can be a regular quadrilateral, and the initiating component 120 is arranged at the center of the regular quadrilateral.

[0060] It is worth noting that the inflating component 130 of the present application can not be limited to four, and in other embodiments, according to different use scenarios, the inflating component 130 can also be more than four, for example, five, six, seven, or eight or more.

[0061] With reference to Figure 1 and Figure 2 In some embodiments, the first mounting portion 141 and the second mounting portion are mounting holes arranged on the shell 140, the fan is an axial fan, and the fan is mounted on the mounting hole of the first mounting portion 141 in the axial direction. Specifically, the air inlet end of the fan faces away from the air bag 110, and the air outlet end faces the air bag 110; the initiating component 120 is in a columnar shape, the initiating component 120 is mounted on the mounting hole of the second mounting portion in the axial direction, the initiating component 120 has an exhaust end, and the exhaust end is connected to the first air inlet 111.

[0062] In some embodiments, in order to realize the triggering of the inflator 120 and the inflating component 130, the airbag assembly 100 further comprises a controller, the inflator 120 and the inflating component 130 are electrically connected with the controller, the controller is configured to send a triggering signal to the inflator 120 and send a starting signal to the inflating component 130, so that the inflator 120 is triggered, and the inflating component 130 is triggered synchronously, thereby improving the deployment speed of the airbag 110.

[0063] In some embodiments, a power supply assembly is further included, and the power supply assembly is configured to supply power to the inflating component 130.

[0064] The application further provides an aircraft, which comprises a fuselage and the airbag assembly 100 according to any one of the above embodiments, and the airbag assembly 100 is mounted on the fuselage.

[0065] In the application, the aircraft can be a lander or a flying vehicle, when the aircraft is a flying vehicle, the flying vehicle can be a manned flying vehicle or a drone, and the airbag assembly 100 can be mounted on the belly or the landing gear of the manned flying vehicle or the drone, when the manned flying vehicle or the drone is a multi-rotor flying vehicle, the airbag assembly 100 can be mounted on the arm of the multi-rotor flying vehicle.

[0067] During the forced landing of the aircraft, the airbag 110 is compressed after being in contact with the ground, and during the compression process, the kinetic energy of the aircraft is converted into the potential energy of the compressed gas in the airbag 110, so that the descending speed of the aircraft at the moment of contact with the ground can be significantly slowed down, and the aircraft can be protected from damage.

[0068] Furthermore, compared with the related art, the airbag assembly 100 has a lighter overall weight, because the airbag 110 does not need to be manually triggered to be ejected, and the airbag 110 does not need to be inflated by a high-pressure gas cylinder, which is beneficial to reduce the weight of the entire aircraft and meet the lightweight demand of the aircraft.
