Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicles (UAVs), and in particular to an attached UAV anti-falling-into-water bionic airbag device. Background Art

[0002] Currently, most rotary-wing drones lack waterproofing. A drop into water during use can severely damage the drone's circuit boards, rendering them irreparable. For one thing, existing anti-water protection accessories suitable for various rotary-wing drone models are scarce, and even fewer have protective devices that can anticipate a water drop and activate in advance. Existing drone anti-water protection features typically activate only after the drone enters the water, which doesn't address the need to prevent the drone from entering water. Furthermore, if a drone malfunctions and falls into water, it can only transmit its last location. Water damage to the circuit boards prevents the drone from transmitting any further location information. Furthermore, the movement of the drone's position due to water flow significantly hinders its recovery. Summary of the Invention

[0022] The invention will be further described in detail below with reference to the accompanying drawings.

[0023] Figures 1 to 9 An attached drone anti-water bionic airbag device according to an embodiment of the present invention is schematically shown.

[0024] Reference Figures 1 to 9 A bionic airbag device for preventing a drone from falling into water includes a main body 1, an alarm 2, an airbag device 3, a power switch 4, a distance detector 5, a warning flashing light 6, an acceleration detector 7, a GPS locator 8, a PE hexagonal roller 9, an elastic nylon rope 10, an adhesive sheet 11, a power supply compartment 12, and a wire 13. The power switch 4, distance detector 5, acceleration detector 7, GPS locator 8, and power supply compartment 12 are all fixed to the main body 1. The PE hexagonal rollers 9 are arranged in parallel to form a PE hexagonal roller belt. One end of the elastic nylon rope 10 is connected to the main body 1, and the other end of the elastic nylon rope 10 passes through the PE hexagonal roller belt and is connected to the adhesive sheet 11. The adhesive sheet 11 and the PE hexagonal roller belt are respectively provided in two and connected to both sides of the main body 1. Two airbag devices 3 are provided, one of which is fixed to the outside of the main body 1, and the other is fixed to the outside of the adhesive sheet 11.

[0025] Reference Figures 4 to 8The two adhesive sheets 11 can be bonded to each other. When in use, the main body 1 is placed on one side of the drone 14. Two PE hexagonal roller belts are wrapped around both sides of the drone 14 and then the two adhesive sheets 11 are bonded together to install the device on the drone 14. After being worn, the two airbag devices 3 are respectively located on the abdomen and back of the drone 14.

[0026] The power switch 4, the distance detector 5, the acceleration detector 7 and the GPS locator 8 are electrically connected to the power supply compartment 12. The power switch 4 is used to control the working state and stop of the instrument and control whether the power supply is energized.

[0027] Airbag device 3 is equipped with a gas generator, which can be a DTN model DTN60P. The gas generator's gas outlet is connected to a custom-shaped, inflatable PA66 high-strength fiber fabric airbag. The airbag's shape is lifelike, employing a multi-legged structure reminiscent of a water strider or spider. A ring-shaped connection at the bottom of the airbag creates an outward-expanding, hollowed-out structure. This allows the airbag to conform to the water surface to prevent capsizing upon contact. Furthermore, its downward-opening, hollowed-out design prevents confluence and water accumulation.

[0028] The acceleration detector 7 is electrically connected to the distance detector 5. It monitors real-time acceleration and can transmit an activation signal to the distance detector 5. The brand of the acceleration detector 7 is likely Analog Devices, model number ADIS16204BCCZ. The acceleration detector 7 is connected to the power supply compartment 12, the distance detector 5, and the airbag device 3. By monitoring the drone's real-time acceleration, it transmits an abnormality signal to the airbag device and an activation signal to the distance detector if the acceleration is abnormal.

[0029] The distance detector 5 is electrically connected to the airbag device 3. It detects distance information and transmits an activation signal to the airbag device 3. A typical brand of distance detector 5 is TF-Luna from Beixing. The distance detector 5 is connected to the power supply compartment 12, the acceleration detector 7, and the airbag device 3. It is activated by an abnormal signal transmitted by the acceleration detector 7 and transmits an activation signal to the airbag device when the measured distance to the ground reaches five meters.

[0030] The GPS locator 8 is a Concord model GT741. It is connected to the power supply compartment 12 and the airbag device 3. When the airbag device 3 is deployed, it sends real-time location information to a remote signal receiving device. The remote signal receiving device can be a mobile phone, computer, or other signal receiving device.

[0031] One end of the wire 13 passes through the main body 1, and the other end of the wire 13 passes through the PE hexagonal roller tape and is connected to the airbag device 3 outside the adhesive sheet 11. The airbag device 3 is connected to the components inside the main body 1 through the wire 13 and transmits signals.

[0032] The alarm 2 and the warning flashing light 6 are fixed to the main body 1. The alarm 2 is electrically connected to the power supply compartment 12 and the airbag device 3. The alarm 2 is triggered and emits an alarm sound after the airbag device is in a ready state.

[0033] The warning flashing light 6 is electrically connected to the power supply compartment 12 and the airbag device 3 . The warning flashing light 6 is triggered and emits a flashing warning light after the airbag device is turned on in the ready state.

[0034] The PE hexagonal roller 9 is located outside the device body and connected by an elastic nylon rope 10. A single PE hexagonal roller belt can utilize two elastic nylon ropes 10. Made of PE, it boasts low mass, low density, corrosion resistance, and a soft, yet durable material. The hexagonal structure allows the wristband to be bent into various curved configurations, providing a closer fit with the surfaces of various drone models 14, while maintaining high friction and preventing damage to the drone's surface.

[0035] The elastic nylon rope 10 is located outside the device body and is connected in series with the PE hexagonal roller. It is durable and not easy to break, and has strong elasticity.

[0036] The power supply compartment 12 is the device's primary power supply system and contains a removable battery. It is connected to the power switch, distance sensor, acceleration sensor, airbag trigger, GPS locator, flashing warning lights, and loudspeaker alarm. This provides power to detect if the drone is accelerating downward, deploy the airbag at the appropriate time, and generate an audible and visual alarm.

[0037] The present invention provides a convenient and safe attachable drone anti-water bionic airbag device. The operating steps are as follows:

[0038] Step 1) Wear the device. Install the device on the waist of the drone with the device panel facing downward. Tighten the elastic nylon rope to make it fit tightly against the drone and use the adhesive sheet to secure it.

[0039] Run step 2) to turn on the device. Press the power button.

[0040] Run step 3) Due to the drone falling, the acceleration detector detects an abnormal value, and the acceleration detector sends an abnormal signal to the airbag device, triggering the airbag device's "ready mode". The acceleration detector sends a start signal to the distance detector.

[0041] After step 4) "Ready Mode" is turned on, the warning light will flash and the alarm will sound, which will facilitate the fault warning and the drone recovery work.

[0042] Operation step 5) The distance detector is started to monitor the height above the ground in real time. When the ground distance is 5m, a start signal is transmitted to the airbag device.

[0043] Operation step 6) The airbag device is in the "ready mode" and receives the start signal transmitted by the distance detector, triggering the airbag device "opening mode" to generate gas to inflate the airbag, causing the airbag to explode.

[0044] Run step 7) The GPS locator starts and transmits the drone's location information in real time.

[0045] After completing the above steps, the drone's anti-falling water protection is completed.

[0046] The attached drone anti-water-falling bionic airbag device of the present invention has the following advantages:

[0047] 1) The device is stick-on and easy to install and remove. No modification is required to the original drone model. It is easy to use. The PE wrist strap can protect the drone casing from damage during use.

[0048] 2) Comprehensive coverage and safe deployment before entering the water significantly reduces the possibility of motor damage caused by a drone falling into the water. ① Two airbags, A and B, are installed on the drone's abdomen and back, respectively. Their high degree of coverage prevents the drone from sinking into water regardless of its landing posture. ② The airbag deploys before contact with water, preventing the drone from sinking. ③ The airbag trigger sequence is as follows: upon detecting an abnormal speed, the distance detector activates, and the drone ejects at a height of five meters from the ground. This procedure prevents false triggering during low-altitude flight and prevents premature deployment in mid-air, which could cause the drone to flip.

[0049] 3) The airbag system features an anthropomorphic shape, resembling the multi-legged structure of water striders and spiders. Rings connect the bottom of the airbag, creating an outward-expanding, hollowed-out structure. This structure conforms to the water surface to prevent capsizing upon contact, while also preventing confluence and water accumulation due to the downward-opening, hollowed-out shape of the airbag.

[0050] 4) The device uses a PE hexagonal roller to connect the wristband. The hexagonal structure allows the connected wristband to be bent into different curved structures, which fits more closely with the surface of different types of drones. It has high friction and the soft material will not cause damage to the drone surface.

[0051] 5) The device is equipped with a locator, which contains a positioning and data transmitting device, which is used to send real-time positioning information data to facilitate the recovery of drones.

[0052] 6) The device is equipped with an audible and visual alarm device, which facilitates the recovery of drones through flashing lights and sharp alarm sounds.

[0053] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the invention.
