Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, in particular to a unmanned aerial vehicle with a protective structure. Background Art

[0002] There are many types of drones, some of which are called unmanned aircraft. They are mainly divided into two major fields: military and civilian. Drones are controlled by program or radio remote control, such as for aerial photography, survey, mapping, news reporting, etc.

[0003] Drones commonly use lithium polymer batteries for battery life. Before driving, you need to confirm the battery level to reduce the possibility of low battery during driving. Then connect the drone and the remote control, start the corresponding software, turn on the power button, calibrate the compass, and perform other operations.

[0004] Due to external factors, such as strong winds, bad weather and other uncontrollable factors, the battery power may be consumed faster, resulting in insufficient power. When the drone is crossing the lake at this time, it may fall into the water due to insufficient power. Subsequent salvage requires a certain amount of time, which may cause a large amount of water to seep into the drone, causing damage to internal components and short circuit. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model proposes a drone with a protective structure.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the utility model is a drone with a protective structure, comprising a body; a mounting box is installed inside the bottom end of the body; a high-pressure gas cylinder bin is installed inside the mounting box, and a gas pipe is connected to the gas delivery end of the high-pressure gas cylinder bin; a connecting plate is connected around the outer wall of the mounting box, and an airbag is fixedly connected to one end of the connecting plate; a limiting frame is fixedly connected around the outer wall of the mounting box, and each group of limiting frames is located on one side of the airbag; one end of the limiting frame is hinged to the limiting plate through a torsion spring.

[0007] Preferably, multiple groups of card frames are fixed around the bottom end of the body, and multiple groups of first springs are fixed equidistantly inside the card frames; a card plate is elastically and slidably connected to the inside of the card frames through the first springs; multiple groups of receiving plates are fixed around the outer wall of the installation box, and the receiving plates and the card frames are arranged in corresponding positions; one end of the card plate is plugged into the inside of the receiving plate.

[0008] Preferably, a connecting column is fixed at the center of the bottom side of the installation box, and multiple groups of first connecting rods are fixed around the connecting column; a second connecting rod is fixed to one side of the connecting plate; the second connecting rod and the end of the first connecting rod are both fixed with screws, and the two groups of screws are connected by a threaded sleeve; the length of the screw is greater than the length of the threaded sleeve.

[0009] Preferably, a plurality of groups of reinforcing ribs are equidistantly fixed to the inner wall of the airbag, and the reinforcing ribs are made of rubber.

[0010] Preferably, a plurality of groups of positioning columns are fixedly connected at equal distances to one end of the installation box, and a plurality of groups of positioning grooves are correspondingly provided inside the bottom end of the body.

[0011] Preferably, a spring column is provided inside the wing at the bottom end of the body, and a universal wheel is installed at one end of the spring column.

[0012] Preferably, the airbag is made of lightweight and waterproof material, such as nylon or polyester.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model provides a drone with a protective structure. When the drone is short of power and is about to fall into water, the electromagnetic valve is controlled to open by a remote controller, so that the gas supply end of the high-pressure gas cylinder warehouse transmits gas to the inside of the airbag through the air pipe, so that the airbag is quickly extended. When the drone falls into water, the airbag provides buoyancy support for the drone, so that the drone floats on the water surface, reduces the damage to the drone during the period of waiting for salvage, and achieves the effect of protecting the drone. The airbag is arranged in four groups, which provides stable, uniform and sufficient buoyancy for the drone when it falls into water, so that it can land safely on the water surface. At the same time, during the extension process of the airbag, it will continue to squeeze the limit plate, so that the limit plate is flipped and rotated through the torsion spring, reducing the impact on the normal extension of the airbag, and the limit plate is set by the torsion spring to fix the stored airbag.

[0015] 2. The utility model provides a UAV with a protective structure. By pulling the card plate, one end of the card plate is detached from the inside of the receiving plate, and the installation box can be quickly detached from the bottom of the body, which is convenient for the subsequent disassembly and replacement of several components arranged inside the installation box. At the same time, when the installation box is inserted into the body, the card plate is inserted into the inside of the receiving plate under the thrust of the first spring, so that the effect of quick disassembly and installation is achieved.
