Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a protective shell. Background Art

[0002] Compared with traditional cameras, drones can record the scenery along the way, which can show more open and spectacular scenery, and can also bring unique shooting experience to travelers. Drones are composed of flight control power system, remote control system, gimbal camera and drone frame. However, during the flight, drones still have the risk of falling from the air. The existing drone protection structure is often a hard protective frame. Although it can support the landing gear of the drone to a certain extent, it lacks elastic protection structure for the collision point of the drone, resulting in an increased risk of damage to the aerial camera carried at the bottom of the drone after it falls. For this reason, we propose a protective shell that can reduce the risk of damage to the drone. Utility Model Content

When the drone falls from the air, the buoyancy of the air on the baffle causes the baffle to pull the length extension rod to rotate around the central axis of the circular shaft, and the surface of the torsion spring passes through a dynamic protective shell structure, which provides anti-collision protection for the tail end of the drone.

[0005] As a further solution of the utility model: a support rod is welded at the bottom of the connecting rod, and a limit rod is welded at the top of the connecting rod. Both the support rod and the limit rod are U-shaped rods, which can form a recess adapted to the landing gear, so as to facilitate the adaptation and connection between the annular airbag and the landing gear.

[0006] As a further solution of the utility model: the side of the annular airbag is connected to an inflation valve, and an air pump is used to connect the inflation valve to inflate the annular airbag.

When the UAV falls from the air, the buoyancy of the air on the baffle causes the baffle towing length extension rod to rotate around the central axis of the circular shaft, and the head and tail ends of the UAV are protected by the dynamic protective shell structure.

[0008] As a further solution of the utility model: a length extension rod is welded at one end of the pulling rod, and a support foot is vertically welded at one end of the length extension rod. The support foot is a U-shaped rod, and the support foot is symmetrical about the center line of the connecting rod. The support foot serves as a bottom supporting structure and plays a lifting role.

[0009] As a further solution of the utility model: a fixing rod is welded to one side of the length extension rod, a baffle is glued to the surface of the fixing rod, the bottom surface of the baffle or the cross-section of its bottom surface is coplanar with the bottom surface of the supporting foot, and the baffle can assist the supporting foot in supporting the protective shell.

[0010] As a further solution of the utility model: the baffle is a curved plate, and reinforcing rods are fixed between the two sides of the baffle and the length extension rods to improve the connection stability of the baffle.

[0011] As a further solution of the utility model: an aerial camera is connected to the lower end of the drone, and the annular airbag facing the aerial camera can protect the aerial camera.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides an annular airbag connected to the landing gear, and can cooperate with the U-shaped frame to provide anti-collision protection for the bottom of the drone. The annular airbag is clamped with the landing gear, and the annular airbag can be inflated or deflated through the inflation valve, which makes it easy to disassemble the protective shell. By providing the annular airbag facing the aerial camera, the aerial camera can be protected.

[0014] 2.
