Description

Technical Field

[0001] The present invention relates to the technical field of protection devices, and particularly to an airbag type automatic protection device for drone crashes. Background Art

[0002] An unmanned aerial vehicle, abbreviated as "drone", is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device, or is operated completely or intermittently autonomously by an on - board computer.

[0003] With the progress of drone technology and the expansion of its application scope in recent years, drones have been widely used in civilian and military fields. However, during flight, drones may malfunction or even crash due to internal and external factors, which not only causes huge economic losses to drone owners, but also may endanger human life safety.

[0004] Currently, there are mainly four types of drone crash protection devices: First, improving the stability of the control system during flight, but this solution is greatly affected by the environment and cannot avoid drone crashes caused by external factors. Second, installing a parachute, which cannot ensure safe and stable landing in harsh environments or below the minimum parachute - opening altitude. Third, installing shock - absorbing brackets, but the protection ability of installing shock - absorbing brackets during drone crashes is limited and there are limitations in terms of aircraft models. Fourth, installing airbags, although the protection against drone crashes is safer and more reliable, it lacks universality, economy, and environmental adaptability, and has obvious disadvantages. In the prior art, gravity sensors have been used to monitor the state of drones. However, gravity sensors are relatively expensive, have a low cost - effectiveness ratio, and poor sensitivity, and cannot accurately determine the real - time state of drones. Summary of the Invention

[0005] The present invention discloses an airbag type automatic protection device for drone crashes, aiming to solve the problems raised in the background art.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An airbag type automatic protection device for drone crashes, comprising:

[0008] A drone body and a protection mechanism, the protection mechanism is arranged on the upper and lower surfaces of the drone body;

[0009] The protection mechanism includes two mounting shells respectively arranged on the upper surface and the lower surface of the drone body, and an airbag assembly, a gas cylinder assembly, and a control assembly respectively arranged inside the mounting shells;

[0010] The airbag assembly includes an airbag main body folded and arranged inside the mounting shell, and an inflation nozzle arranged on the surface of the airbag main body;

[0011] The gas cylinder assembly includes a high-pressure gas cylinder body disposed inside the installation housing, and a control valve disposed at the bottle mouth of the high-pressure gas cylinder body;

[0012] The control assembly includes a power module, a detection module, and an insulating spring capacitor.

[0013] In a preferred embodiment, an installation frame is fixedly provided on the inner wall of the installation housing. The installation frame has an upper opening structure, and the airbag body is folded and disposed inside the installation frame. A rectangular opening adapted to the installation frame is provided on the upper surface of the installation housing, and a film is adhesively disposed on the inner wall of the rectangular opening.

[0014] By providing the installation frame and the film, when the UAV body is operating normally, the airbag body can be folded and stored inside the installation frame and sealed by the film. When the UAV body falls, the airbag body can be inflated by the high-pressure gas cylinder body and expand, then push out the film, so that the airbag body unfolds on the outer surface of the UAV body.

[0015] In a preferred embodiment, an inflation hole is provided on the inner side wall of the installation frame, and an inflation nozzle is fixedly provided inside the inflation hole. An inflation channel corresponding to the inflation hole is fixedly provided on the side surface of the installation frame, and the inflation end of the high-pressure gas cylinder body is threadedly connected inside the inflation channel.

[0016] By providing the inflation channel, on the one hand, the high-pressure gas cylinder body can be threadedly connected to the inflation channel to achieve rapid installation and disassembly of the high-pressure gas cylinder body. On the other hand, the high-pressure gas cylinder body can inflate the inflation nozzle on the airbag body through the inflation channel, so as to achieve the purpose of quickly inflating the airbag body.

[0017] In a preferred embodiment, after the high-pressure gas cylinder body inflates the airbag body through the inflation channel, the airbag body pushes open the film and extends into a plurality of crescent shapes on the outer surface of the UAV body.

[0018] By designing the airbag body into a plurality of crescent shapes, the UAV body and its components thereon can be completely wrapped in all directions, ultimately achieving the purpose of protecting the UAV body from falling.

[0019] In a preferred embodiment, the insulating spring capacitor includes an upper electrode plate and a lower electrode plate disposed inside the installation housing, and the upper electrode plate is disposed above the lower electrode plate. An insulating spring body is disposed between the upper electrode plate and the lower electrode plate. Both ends of the insulating spring body are fixedly connected to the opposite surfaces of the two upper electrode plates and the lower electrode plate respectively, and a gravity hammer is disposed in the middle of the insulating spring body.

[0020] By setting the upper plate, the lower plate and the insulating spring body, in the initial state, due to the gravitational forces of the upper plate and the gravity hammer, the insulating spring body is in a compressed state and provides a repulsive force between the upper plate and the lower plate. At this time, the capacitance value between the upper plate and the lower plate is relatively large. When the drone body is in a state of weightlessness, the upper plate, the lower plate and the gravity hammer are all in a state of weightlessness. Under the action of elastic potential energy, the insulating spring body changes from the compressed state to the stretched state, the distance between the upper plate and the lower plate changes, and the capacitance value changes.

[0021] In a preferred embodiment, the control component further includes a gyroscope-like bracket disposed inside the mounting housing, and the insulating spring capacitor is disposed inside the gyroscope-like bracket.

[0022] By setting the gyroscope-like bracket, to prevent the lateral relative displacement between the upper plate and the lower plate caused by external factors such as jolts and tilts during daily use, which may change the capacitance and cause the airbag body to be accidentally triggered. The insulating spring capacitor is specifically placed in the gyroscope-like bracket to ensure its horizontal stability and avoid accidental triggering of the airbag body.

[0023] In a preferred embodiment, the detection module is electrically connected to the lower plate, and it is used to detect the capacitance value of the capacitor, and the control valve is electrically connected to the detection module through a wire.

[0024] In a preferred embodiment, double-sided tapes are adhesively fixed to the opposite surfaces of the two mounting housings, and the other surface of the double-sided tape away from the mounting housing is adhesively fixed to the outer surface of the drone body.

[0025] By setting the double-sided tapes, the two mounting housings can be respectively installed on the upper surface and the lower surface of the drone body, so that the protection mechanism has the advantages of simple shape, convenient installation, and strong versatility.

[0026] As can be seen from the above. An airbag-type automatic drone fall protection device provided by the present invention has the following technical effects.

[0027] First: After the overall protection mechanism is installed on the drone body, it has a compact structure, small size, simple and light weight, convenient installation, and does not require the installation of other auxiliary devices. It has strong versatility and can be applied to various drones.

[0028] Second: Since the upper plate, the lower plate and the detection module in the protection mechanism are all relatively low-cost parts, compared with the gravity sensors in the prior art, the cost is lower. Therefore, the device has a high cost performance, and at the same time has a high precision and can detect the state of the drone in real time.

[0029] Thirdly: It can achieve all-round protection of the UAV body, be applicable to various complex environments, have waterproof performance, and greatly reduce the harm caused by the UAV falling.

[0030] Fourthly: When the UAV falls into a water environment, it floats relying on the airbag, preventing the device from being immersed in water, and the device can be reused by replacing the high-pressure gas cylinder body and folding the airbag body. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0045] Refer to Figure 1-10 , an airbag-type automatic protection device for the fall of an unmanned aerial vehicle, comprising:

[0046] The unmanned aerial vehicle body 100 and the protection mechanism 200, and the protection mechanism 200 is arranged on the upper and lower surfaces of the unmanned aerial vehicle body 100;

[0047] The protection mechanism 200 includes two installation housings 201 respectively arranged on the upper surface and the lower surface of the unmanned aerial vehicle body 100, and an airbag assembly 202, a gas cylinder assembly 203 and a control component 204 respectively arranged inside the installation housings 201;

[0048] Refer to Figure 1 , in a preferred embodiment, double-sided adhesives are adhesively fixed to the opposite surfaces of the two installation housings 201, and the other surface of the double-sided adhesive away from the installation housing 201 is adhesively fixed to the outer surface of the unmanned aerial vehicle body 100.

[0049] Specifically, by setting the double-sided adhesive, the two installation housings 201 can be respectively installed on the upper surface and the lower surface of the unmanned aerial vehicle body 100, so that the protection mechanism 200 has the advantages of simple shape, convenient installation and strong versatility.

[0050] The airbag assembly 202 includes an airbag main body 2021 that is folded and arranged inside the installation housing 201, and an inflation nozzle 2022 arranged on the surface of the airbag main body 2021;

[0051] Referring to Figure 1 and 5 In a preferred embodiment, an installation frame 2023 is fixedly arranged on the inner wall of the installation housing 201. The installation frame 2023 has an upward opening structure, and the airbag main body 2021 is folded and arranged inside the installation frame 2023. A rectangular opening adapted to the installation frame 2023 is formed on the upper surface of the installation housing 201, and a thin film 2024 is adhesively arranged on the inner wall of the rectangular opening.

[0052] The gas cylinder assembly 203 includes a high-pressure gas cylinder main body 2031 arranged inside the installation housing 201, and a control valve 2032 arranged at the bottle mouth of the high-pressure gas cylinder main body 2031.

[0053] Specifically, by arranging the installation frame 2023 and the thin film 2024, when the UAV body 100 is operating normally, the airbag main body 2021 can be folded and stored inside the installation frame 2023 and sealed by the thin film 2024. When the UAV body 100 falls, the airbag main body 2021 can be inflated by the high-pressure gas cylinder main body 2031 and expand, pushing out the thin film 2024, so that the airbag main body 2021 unfolds on the outer surface of the UAV body 100.

[0054] Referring to Figure 5 In a preferred embodiment, an inflation hole is formed on the inner side wall of the installation frame 2023, and the inflation nozzle 2022 is fixedly arranged inside the inflation hole. An inflation channel 2033 corresponding to the inflation hole is fixedly arranged on the side surface of the installation frame 2023, and the inflation end of the high-pressure gas cylinder main body 2031 is threadedly connected inside the inflation channel 2033.

[0055] Specifically, by arranging the inflation channel 2033, on the one hand, the high-pressure gas cylinder main body 2031 can be threadedly connected to the inflation channel 2033 to realize the quick installation and disassembly of the high-pressure gas cylinder main body 2031. On the other hand, the high-pressure gas cylinder main body 2031 can inflate the inflation nozzle 2022 on the airbag main body 2021 through the inflation channel 2033, so as to realize the purpose of quickly inflating the airbag main body 2021.

[0056] Referring to Figure 2 and Figure 4 In a preferred embodiment, after the high-pressure gas cylinder main body 2031 inflates the airbag main body 2021 through the inflation channel 2033, the airbag main body 2021 pushes open the thin film 2024 and extends into a plurality of crescent shapes on the outer surface of the UAV body 100.

[0057] Specifically, by designing the airbag body 2021 into a plurality of crescent shapes, the drone body 100 and its components thereon can be completely wrapped in all directions, ultimately achieving the fall protection of the drone body 100.

[0058] The control component 204 includes a power module 2041, a detection module 2042, and an insulating spring capacitor 2043.

[0059] Refer to Figure 5 , in a preferred embodiment, the insulating spring capacitor 2043 includes an upper electrode plate 20431 and a lower electrode plate 20432 disposed inside the mounting housing 201, and the upper electrode plate 20431 is disposed above the lower electrode plate 20432. An insulating spring body 20433 is disposed between the upper electrode plate 20431 and the lower electrode plate 20432. Both ends of the insulating spring body 20433 are fixedly connected to the opposite surfaces of the two upper electrode plates 20431 and the lower electrode plate 20432 respectively. A gravity hammer 20434 is disposed in the middle of the insulating spring body 20433. The purpose is to make the insulating spring body 20433 have a certain amount of compression in the normal state. When the drone crashes, the gravity hammer 20434 and the upper electrode plate 20431 are in a weightless state, and the insulating spring body 20433 elongates under the action of elastic force, causing the capacitance to change.

[0060] Specifically, by setting the upper electrode plate 20431, the lower electrode plate 20432, and the insulating spring body 20433, in the initial state, due to the gravitational action of the upper electrode plate 20431 and the gravity hammer 20434, the insulating spring body 20433 is in a compressed state and provides a repulsive force between the upper electrode plate 20431 and the lower electrode plate 20432. At this time, the capacitance value between the upper electrode plate 20431 and the lower electrode plate 20432 is relatively large. When the drone body 100 is in a weightless state, both the upper electrode plate 20431 and the lower electrode plate 20432 are in a weightless state. Under the action of elastic potential energy, the insulating spring body 20433 changes from a compressed state to an elongated state, the distance between the upper electrode plate 20431 and the lower electrode plate 20432 changes, and the capacitance value changes.

[0061] Refer to Figure 5 , in a preferred embodiment, the control component 204 further includes a gyroscope-like bracket 2044 disposed inside the mounting housing 201, and the insulating spring capacitor 2043 is disposed inside the gyroscope-like bracket 2044.

[0062] Specifically, by setting up a gyroscope-like bracket 2044, to prevent the lateral relative displacement between the upper electrode plate 20431 and the lower electrode plate 20432 during daily use due to external factors such as bumps and tilts, which may cause changes in capacitance and lead to the accidental triggering of the airbag main body 2021, the insulated spring capacitor 2043 is specifically placed in the gyroscope-like bracket 2044 to ensure its horizontal stability and avoid the accidental triggering of the airbag main body 2021.

[0063] Referring to Figure 5 , in a preferred embodiment, the detection module 2042 is electrically connected to the lower electrode plate 20432, which is used to detect the capacitance value of the capacitor, and the control valve 2032 is electrically connected to the detection module 2042 through a wire.

[0064] Among them, this module has a low cost and can effectively monitor the state of the drone in real time. The insulated spring capacitor 2043 is installed on the gyroscope-like bracket 2044, thereby reducing the capacitance error detected by the insulated spring capacitor 2043 due to external factors such as bumps and tilts, ensuring that the insulated spring capacitor 2043 can correctly reflect the acceleration of the drone in real time and convert it into a capacitance signal. The capacitance signal judges the operating state of the drone through data processing in the detection module 2042 and controls the activation switch of the airbag, thereby realizing the protection of the drone.

[0065] When the capacitance value detected by the detection module 2042 does not continuously reach the preset value, it means that the drone body 100 is in a normal state and the control valve 2032 is not activated; when the capacitance value detected by the detection module 2042 continuously reaches the preset value, it means that the drone body 100 has a fault and falls. At this time, the detection module 2042 automatically controls the control valve 2032 to open, and the gas cylinder body 2031 is opened to inflate the airbag main body 2021 through the inflation channel 2033. The specific capacitance preset value and duration are obtained based on multiple free-fall tests. The specific method is as follows:

[0066] Through the research on the normal falling state and the fault crashing state of the drone, the relationship between the acceleration of the drone and the capacitance value of the protection device is determined, so as to realize the conversion from the acceleration signal to the capacitance signal, and finally determine the capacitance preset value. Under normal conditions, the acceleration of the drone will not be equal to the gravitational acceleration for a long time, that is, the capacitance value corresponding to the normal state will not be equal to the capacitance value corresponding to the state of gravitational acceleration for a long time. Taking a certain drone's normal falling state and fault crashing state as an example, study the relationship between its acceleration and capacitance. From Figure 9 and Figure 10It can be known that under normal operating conditions, the capacitance value of the drone remains constant at a uniform speed. Under an accelerating state, the capacitance value will experience a brief fluctuation. However, due to the short acceleration time and the relatively small acceleration compared to the gravitational acceleration, the capacitance value is significantly different from that in the fault crash state. Thus, the specific capacitance preset value and duration can be determined.

[0067] In summary, for the technical solution proposed in this application, after the overall protection mechanism 200 is installed on the drone body 100, the structure is compact, the volume is small, it is simple, lightweight, and easy to install. Moreover, no other auxiliary devices need to be installed, and it has strong versatility and can be applied to various drones. Also, since the upper plate 20431, the lower plate 20432, and the detection module 2042 in the protection mechanism 200 are all relatively low-cost parts, the cost is lower than that of the gravity sensor in the prior art. As a result, the device has a high cost performance, and at the same time, it has high precision, can detect the state of the drone in real time, and can achieve all-round protection of the drone body 100. It is applicable to various complex environments, has waterproof performance, and greatly reduces the harm caused when the drone falls.

[0068] Therefore, for the technical solution proposed in this application, when the drone falls, the detection module 2042 controls the high-pressure gas cylinder body 2031 to quickly inflate the airbag body 2021, wrapping the drone body 100 all around. And the model adopts a capsule design with strong versatility. When the drone falls to the ground, it relies on the airbag for buffering, thus achieving all-round protection of the drone. At the same time, when the drone falls into a water environment, it floats relying on the airbag to avoid the device from being immersed in water, and the device can be reused by replacing the high-pressure gas cylinder body 2031 and folding the airbag body 2021.

[0069] Working principle: When the UAV body 100 is flying normally, due to the gravitational forces of the upper plate 20431 and the gravity hammer 20434, the insulating spring body 20433 is in a compressed state and provides a repulsive force between the upper plate 20431 and the lower plate 20432. At this time, the capacitance value between the upper plate 20431 and the lower plate 20432 is relatively large. When the UAV body 100 experiences an out-of-control fall, a weightlessness phenomenon occurs. Both the upper plate 20431 and the lower plate 20432 are in a weightless state. Under the action of elastic potential energy, the insulating spring body 20433 changes from a compressed state to an extended state, the distance between the upper plate 20431 and the lower plate 20432 changes, and the capacitance value changes. At this time, when the detection module 2042 detects that the capacitance value continuously reaches the preset value, it means that the UAV body 100 has a failure and falls. At this time, the detection module 2042 automatically controls the control valve 2032 to open, and the high-pressure gas cylinder body 2031 inflates the airbag body 2021 through the inflation channel 2033. After the airbag body 2021 can be inflated and expanded by the high-pressure gas cylinder body 2031, it pushes out the film 2024, so that the airbag body 2021 unfolds on the outer surface of the UAV body 100. At this time, the two airbag bodies 2021 are respectively inflated and extended on the upper and lower sides of the UAV body 100 to form two semi-shell shapes and unfold into a plurality of crescent shapes, which can completely wrap the UAV body 100 and its components thereon in all directions, and finally realize the fall protection of the UAV body 100.

[0070] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution can be a substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
