[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers. Most drones currently on the market are mainly powered by the rotation of fan blades during flight. The airflow generated by the rotation of the blades cuts the air, thereby generating lift, and by changing the angle or speed of the rotor, forward, backward or sideways thrust can be generated, thereby controlling the flight direction of the drone.

[0003] In the existing technology, since the rotor of a drone is a key component in flight and operation, it is usually exposed and easily hit or scratched by obstacles such as branches and wires, which in turn affects the flight performance and operation effect of the drone. Moreover, when the drone is taking off, landing or flying, if the rotor accidentally touches a person, it may cause serious harm, increasing the risk of personal injury. Therefore, a drone with a flight protection structure is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0030] Embodiment: The embodiment provides a UAV with a flight protection structure, referring to Figure 1-5 , specifically, comprising:

[0031] The body 1 is fixedly installed with a support 101 on the outer wall, and the support 101 is rotatably connected with a rotor 102 at the top. When the rotor 102 rotates, the blades cut the air to generate an upward airflow, thereby generating a lifting force to balance the gravity of the UAV and the component parts of the fuselage in the vertical direction. By changing the angle or rotating speed of the rotor 102, forward, backward or lateral thrust can be generated to control the flight direction of the UAV. The outer wall of the support 101 is fixedly provided with a protective assembly, which comprises:

[0032] The protective cover 2 is movably connected to the outer wall of the rotor 102, surrounding the rotor 102 to reduce the chance of the body 1 accidentally hitting obstacles during flight, thereby reducing the probability and severity of accidents. It can also effectively prevent the rotor 102 from cutting people when rotating at high speed, especially when the UAV is operated in crowded areas or at close range;

[0033] The flipping unit includes an arc block 202 and a fixed block 3. The fixed block 3 is fixedly arranged on the outer wall of the bracket 101, and a rotating rod 203 is movably inserted between the fixed blocks 3. The outer wall of the protective cover 2 is fixedly provided with a connecting rod 201, and an arc block 202 is fixedly provided at one end of the connecting rod 201, and the arc block 202 is fixedly provided on the outer wall of the rotating rod 203. When maintenance and inspection of the rotor 102 is required, the operator pushes the arc block 202 upward to make the arc block 202 drive the connecting rod 201 to rotate upward, and the upward rotating connecting rod 201 drives the protective cover 2 to rotate upward, so that the protective cover 2 moves above the rotor 102. At this time, the rotor 102 is completely exposed, which is convenient for daily inspection, maintenance and replacement of parts of the drone.

[0034] The outer wall of the fixed block 3 is fixedly provided with a fixed ring 302, and the outer wall of the rotating rod 203 extends outward through the fixed ring 302 and is fixedly provided with a rotating block 4. When in use, the user holds the rotating block 4 and rotates it upward.

An extrusion spring 402 is fixedly provided on the inner wall of the connecting groove 401, and the other end of the extrusion spring 402 is fixedly provided on the outer wall of the positioning block 403. When in use, the protective cover 2 located above is rotated downward so that the protective cover 2 is sleeved on the outside of the rotor 102. At this time, the positioning block 403 is aligned with the first positioning hole 303, and the pushing force of the extrusion spring 402 pushes the positioning block 403 outward so that the positioning block 403 is inserted into and clamped in the first positioning hole 303, so that the position of the rotating block 4 is fixed, thereby fixing the use position of the protective cover 2, and further improving the stability of the use position of the protective cover 2.

[0036] The outer wall of the rotating block 4 is provided with a sliding groove 404, the outer wall of the positioning block 403 is fixedly provided with a sliding block 405, one end of the sliding block 405 extends outward through the sliding groove 404 to the rotating block 4, and the sliding block 405 is used for extending the action point of the positioning block 403, so that the user can conveniently contact and adjust.

[0037] The outer wall of the sliding block 405 is fixedly provided with a push plate 406, and the push plate 406 covers the sliding groove 404.

[0038] The inner wall of the fixed ring 302 is provided with a second positioning opening 304, when the protective cover 2 is rotated to above the rotor 102, the positioning block 403 is aligned with the second positioning opening 304, and the positioning block 403 is inserted and clamped in the second positioning opening 304, so that the protective cover 2 is kept in the position above the rotor 102, and the protective cover 2 is prevented from falling randomly to affect the operation of the user.

[0039] The outer wall of the fixed ring 302 is fixedly provided with a mark block 301, the mark block 301 is provided with two groups, corresponding to the positions of the first positioning opening 303 and the second positioning opening 304, so that the user can conveniently find the corresponding positions.

[0040] The bottom of the body 1 is provided with a camera module 103, and the bottom of the body 1 is provided with a protection rack 104, and the protection rack 104 is sleeved outside the camera module 103, so as to further protect the camera module 103.

[0041] Specifically, the working principle and operation method of the utility model are as follows:

[0042] In use, the protective cover 2 located above is rotated downward, the protective cover 2 is sleeved outside the rotor 102, the positioning block 403 is aligned with the first positioning opening 303, the positioning block 403 is pushed outward by the pushing force of the compression spring 402, the positioning block 403 is inserted and clamped in the first positioning opening 303, the position of the rotating block 4 is fixed, the protective cover 2 is fixed outside the rotor 102, the surrounding of the rotor 102 is surrounded, the body 1 is prevented from accidentally colliding with obstacles during flight, the probability and severity of accidents are reduced, and the rotor 102 is prevented from cutting personnel during high-speed rotation, especially when the unmanned aerial vehicle is operated in a densely populated area or at a close distance.

[0043] When it is necessary to perform maintenance and inspection on the rotor 102, the operator pushes the push plate 406 toward the center point of the rotating block 4, so that the push plate 406 drives the slider 405 to move, so that the moving slider 405 drives the positioning block 403 to move toward the inner cavity of the connecting groove 401, so that the positioning block 403 is separated from the first positioning port 303. At this time, the arc block 202 is pushed upward, so that the arc block 202 drives the connecting rod 201 to rotate upward, and the upward rotating connecting rod 201 drives the protective cover 2 to rotate upward, so that the protective cover 2 moves to the top of the rotor 102. At this time, the rotor 102 is completely exposed. When the protective cover 2 rotates to the rotor 102, the protective cover 2 is rotated to the rotor 102. 02, the positioning block 403 is aligned with the second positioning port 304, and by releasing the pushing push plate 406, the extrusion spring 402 pushes the positioning block 403, so that the positioning block 403 is inserted into and stuck in the second positioning port 304, so that the protective cover 2 is kept in the position above the rotor 102, avoiding the protective cover 2 from falling down and affecting the user's operation, and facilitating daily inspection, maintenance and replacement of parts of the rotor 102. When the body 1 falls, the anti-plant frame (104) surrounds the camera module 103, so that the camera module 103 is protected, the collision of the camera module 103 is reduced, and the safety is further improved.
