[0002] An unmanned aerial vehicle, abbreviated as UAV, is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device. Currently, UAVs are widely used in aerial photography, agriculture, plant protection, self - shooting, express delivery, disaster relief, wildlife observation, infectious disease monitoring, mapping, news reporting, power line inspection, disaster relief, film and television shooting and other fields.

[0003] A mapping unmanned aerial vehicle is an unpiloted mapping aircraft controlled by a radio remote control device and a self - contained program control device, or is completely or intermittently autonomously operated by an on - vehicle computer. After the UAV mapping is completed, it will land on the ground. The bottom end of the UAV contacts the ground through a support frame. When landing on the ground, the support frame collides with the ground, generating a large vibration. The generated vibration is transmitted to the airframe, which is likely to damage the airframe. Summary of the Utility Model

[0013] For a protection device for a drone proposed by the present utility model, the beneficial effects are as follows:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Embodiment 1: Refer to Figures 1-4 , a protective device for a drone, including a mounting plate 1, the mounting plate 1 is fixedly connected to the bottom end of the drone, and a plurality of first connecting plates 2 are equidistantly connected along the axial direction at the bottom end of the mounting plate 1. Each first connecting plate 2 is inclined away from the mounting plate 1. A groove frame 3 is slidably connected to each first connecting plate 2. A first spring 4 is fixedly connected to each groove frame 3. One end of each first spring 4 is fixedly connected to the first connecting plate 2. An elastic support member 5 is fixedly connected to the bottom end of each groove frame 3.

[0022] Working process:

[0023] When the drone lands, the drone drives the mounting plate 1 to move, the mounting plate 1 drives the first connecting plate 2 to move, the first connecting plate 2 drives the elastic support member 5 to move through the groove frame 3. After the elastic support member 5 contacts the ground and collides, the elastic support member 5 drives the groove frame 3 to move upward after colliding with the ground. The groove frame 3 compresses the first spring 4. After the first spring 4 is compressed, it generates an elastic force. The elastic force generated by the first spring 4 buffers the collision between the elastic support member 5 and the ground, thereby reducing the collision intensity when the drone lands and protecting the drone.

[0024] Embodiment 2: In Embodiment 1, when the elastic support member 5 contacts the ground, the collision intensity with the ground is too large. Refer to Figures 3-4 , as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the elastic support member 5 includes a second connecting plate 51. One end of the second connecting plate 51 is fixedly connected to the groove frame 3. A rotating plate 52 is rotatably connected to the other end of the second connecting plate 51. A second spring 53 is fixedly connected to the rotating plate 52. One end of the second spring 53 is fixedly connected to the second connecting plate 51. A round convex block 54 is fixedly connected to one end of the rotating plate 52. The round convex block 54 contacts the ground. After the round convex block 54 collides with the ground, it pushes the rotating plate 52 upward. After the rotating plate 52 rotates upward, it compresses the second spring 53. After the second spring 53 is compressed, it generates an elastic force. The elastic force generated by the second spring 53 buffers the rotating plate 52, thereby reducing the collision intensity with the ground.

[0025] Embodiment 3: In Embodiment 1, when the drone is flying and approaching a tree, leaves fall on the propeller, thus affecting the rotation of the propeller. Refer to Figure 2, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that a plurality of shielding mechanisms 6 for protecting the propeller are connected at equal intervals along the axial line direction at the bottom end of the mounting plate 1. The shielding mechanism 6 includes a connecting rod 61. One end of the connecting rod 61 is fixedly connected to the mounting plate 1, and the other end of the connecting rod 61 is fixedly connected with a protective frame 62. A protective net 63 is fixedly connected to the upper end of the protective frame 62. A plurality of retaining rods 64 are connected at equal intervals along the arc direction at the upper end of the protective frame 62. The same reinforcing strip 65 is fixedly connected to one ends of the plurality of retaining rods 64. The retaining rod 64 and the reinforcing strip 65 are of an integral structure. The retaining rod 64 fixes the protective frame 62. The protective frame 62 fixes the protective net 63 and the retaining rod 64. The protective net 63 and the retaining rod 64 are located outside the propeller to block leaves and prevent the leaves from falling on the propeller.

[0026] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacement or change, and should be covered within the protection scope of the present utility model.
