[0025] like Figure 1-Figure 5 The drone airdrop device shown includes: a drone body, a base 4, a control component and an airdrop box 14.

[0026] like Figure 1-Figure 2 As shown, the drone body includes a fuselage 1, an arm 2 and a landing gear 3. The arm 2 is arranged on one side of the fuselage 1 and connected to the fuselage 1. There are multiple arms 2, which are arranged at intervals along the circumferential direction of the fuselage 1. The arm 2 is provided with a rotor. The landing gear 3 is arranged at the bottom of the fuselage 1 and connected to the fuselage 1. This is a conventional structure of an existing drone, which is well known to those skilled in the art and will not be described in detail.

[0027] like Figure 2 and Figure 3As shown, the base 4 is arranged below the fuselage 1, a strap 5 is provided on one side of the base 4, and a fixing component is provided on the other side. The fixing component includes a clamping shaft 6, a mounting seat 7 and a limit piece. The mounting seat 7 is fixedly connected to the base 4, the clamping shaft 6 is rotatably arranged on the mounting seat 7, and a through hole 8 is provided on the clamping shaft 6. The strap 5 bypasses the fuselage 1 and is arranged in the through hole 8. The limit piece is used to lock the limit clamping shaft 6.

[0028] The control component includes a main controller, a battery, an electromagnet 13 and a camera. The base 4 is hollow inside and is equipped with the main controller and the battery. The camera is arranged outside the base 4, and the electromagnet 13 is arranged at the bottom of the base 4. The main controller is connected to the battery, and the camera and the electromagnet 13 are respectively connected to the main controller; a magnetic suction part 15 is provided on the top of the airdrop box 14, and the magnetic suction part 15 and the electromagnet 13 are magnetically attracted to fix the airdrop box 14.

[0029] Specifically, in order to solve the problem that conventional drones do not have an airdrop function, the present invention provides a detachable airdrop device, which is mainly composed of a detachable base 4 and an airdrop box 14. The base 4 is fixed to the bottom of the drone body 1 by a strap 5 and a card shaft 6. Figure 2 , Figure 3 and Figure 4 A through hole 8 is provided on the card shaft 6. When in use, the strap 5 goes around the fuselage 1 upward and then goes downward through the through hole 8 of the card shaft 6. Then, the card shaft 6 is rotated, and the strap 5 is continuously wound around the card shaft 6, so that the fuselage 1 can be continuously and tightly held. Then, the limit piece is used to lock the limit card shaft 6, and the card shaft 6 cannot rotate. In this case, the strap 5 can be prevented from loosening, so that the base 4 can be firmly fixed on the fuselage 1.

[0030] When the base 4 needs to be removed, the clamping shaft 6 is rotated in the opposite direction, and the clamping shaft 6 is no longer wrapped with the strap 5. After the strap 5 is loosened, it is taken out from the penetration hole 8 to remove the base 4. Therefore, this detachable form fixed by the strap 5 is simple, easy to use, and does not require the size of the drone body 1. By adjusting the tightness of the strap 5, it can be fixedly installed on drone bodies 1 of different sizes and models, and has a wide range of applications and strong practicality.

[0031] An electromagnet 13 is provided below the base 4. When the electromagnet 13 is powered on, a magnetic field is generated. When the power is off, the magnetic field disappears. A magnetic attraction member 15 is provided on the top of the airdrop box 14. The magnetic attraction member 15 can be magnetically attracted by the electromagnet 13 when powered on, so that the airdrop box 14 can be fixed below the base 4. A camera is provided on the drone to shoot the flight picture. When the drone flies to the place to be airdropped, the operator controls the electromagnet 13 to be powered off through the main controller, and the airdrop operation of the airdrop box 14 can be completed. This airdrop method has a simple structure and is easy to implement.

[0032] In further settings, such as Figure 5As shown, the limiting member includes a worm wheel 9 and a worm 10. The worm wheel 9 is coaxially fixed to one end of the clamping shaft 6. A rod seat 11 is provided on the mounting seat 7. The worm 10 is rotatably mounted on the rod seat 11 and meshes with the worm wheel 9. A hand wheel 12 is fixedly provided at one end of the worm 10. Thus, by manually rotating the worm 10, the worm wheel 9 can be driven to rotate, and after the worm wheel 9 rotates, the clamping shaft 6 can be driven to rotate. The transmission of the worm wheel 9 and the worm 10 is self-locking. After releasing the hand, the clamping shaft 6 can be prevented from rotating in the opposite direction, thereby ensuring that the clamping shaft 6 is locked.

[0033] In this device, the battery is a rechargeable battery, and a charging port is provided on one side of the base 4. The airdrop box 14 is equipped with a parachute to prevent the airdrop box 14 from being damaged when it is airdropped and falls. This is a prior art and will not be described in detail.

[0034] In summary, this device has the following characteristics:

[0035] 1. This device can be installed on the fuselage 1 of the drone, so that the existing drones that do not have the airdrop function can also have the airdrop function. Moreover, the installation method does not require any structural changes on the fuselage 1 of the drone, and has a wide range of applications and few restrictions.

[0036] 2. The base 4 is fixed to the bottom of the drone body 1 by means of the strap 5 and the card shaft 6. The base 4 can be installed and fixed by rotating the card shaft 6 and tightening the strap 5 continuously. This detachable form of fixing with the strap 5 is simple and does not select the size of the drone body 1. By adjusting the tightness of the strap 5, it can be fixedly installed on drone bodies 1 of different sizes and models, which is very convenient.

[0037] 3. An electromagnet 13 is provided below the base 4. By controlling the electromagnet 13 to cut off power, the automatic airdrop operation of the airdrop box 14 can be completed. This airdrop method has a simple structure and is easy to implement.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
