[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an on-board computer. Compared with manned aircraft, drones are often more suitable for dangerous tasks. Drones are currently used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, and romance creation, etc., which has greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology.

[0003] During aerial photography operations, if the operator operates improperly or does not respond in time, the drone may collide with obstacles. When colliding, the first thing to be damaged is the drone's rotor. Damage to the rotor will cause the entire drone to lose power, causing the drone to fall, which will cause economic losses. For this reason, we propose a protective structure for drones to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] Embodiment 1:

[0033] like Figure 1-Figure 4As shown, a protective structure of a drone includes a fuselage 100, the fuselage 100 is arranged in a hexagonal prism shape, six sides of the fuselage 100 are equipped with arms 101, a rotor 102 is installed at the middle of the upper end of each arm 101, a mounting block 103 is fixed at one end of each arm 101 away from each other, and a protective structure is commonly arranged at one end of each mounting block 103 away from each other;

[0034] The protective structure includes a rubber protective ring 104, which abuts against one end of each mounting block 103 away from each other. The cross-section of the rubber protective ring 104 is set to be semicircular. A cavity 105 is opened inside the rubber protective ring 104. A through groove 106 connected to the cavity 105 is opened in the middle of the inner wall of the rubber protective ring 104. A T-slot 107 is opened at one end of each mounting block 103 away from each other, and a matching clip assembly is provided between the rubber protective ring 104 and each T-slot 107.

[0035] The fuselage 100, the arms 101 and the rotors 102 together constitute a multi-rotor UAV. Since the fuselage 100 is in the shape of a hexagonal prism, the arms 101 and the rotors 102 arranged in this way can hover in the air more stably, making it easier to capture more accurate data. The mounting block 103 is an important component connected to the rubber protective ring 104. The rubber protective ring 104 is elastic and can buffer the impact force generated by the collision, thereby reducing the impact on the overall flight of the UAV. The through groove 106 and the cavity 105 can both be used for wiring arrangement to prevent the lines from being exposed and affecting the flight of the UAV.

[0036] When the UAV is about to hit an obstacle: the first thing that comes into contact with the obstacle is the rubber protective ring 104. Since there is a cavity 105 inside the rubber protective ring 104, it has a certain buffering effect during collision, which can effectively alleviate the impact on the flight of the UAV. At the same time, the rubber protective ring 104 is completely wrapped around the outside of each rotor 102, which can play a good protective role on the rotor 102, thereby indirectly protecting the UAV, so as not to cause damage to the UAV and cause serious economic losses.

[0037] In this embodiment, by installing a rubber protective ring 104 on the outer side of the outermost edge of the arm 101, not only the impact force generated when the drone collides can be reduced, but also the impact on the rotor 102 during the collision can be prevented, thereby ensuring the flight safety of the drone and reducing the cost of the drone.

[0038] Embodiment 2:

[0039] like Figure 1-Figure 6As shown, based on the first embodiment, other components on the protective structure of a drone are further described. The snap-on assembly includes two n-shaped fixing blocks 200. One end of the two n-shaped fixing blocks 200 is fixedly connected to the inner wall of the rubber protective ring 104. The other ends of the two n-shaped fixing blocks 200 are respectively snapped into the inside of the T-shaped slot 107. The two n-shaped fixing blocks 200 are symmetrical to each other with the through slot 106.

[0040] The n-shaped fixing block 200 extends out of one side of the T-shaped slot 107 to fix the limiting block 201 .

[0041] A plurality of evenly distributed mounting holes 202 are provided on the outside of the cavity 105 , and a plurality of cameras 203 are placed inside the cavity 105 . The head of each camera 203 is located inside the corresponding mounting hole 202 , and the tail of each camera 203 is provided with a block 204 that is engaged with the through slot 106 .

[0042] A groove 205 is formed at the lower end of each arm 101 , and the groove 205 is connected to the T-shaped groove 107 . A plurality of protection rods 206 are fixed inside each groove 205 .

[0043] A chassis 300 is fixed in the middle of the lower end of the fuselage 100, and four evenly distributed rectangular grooves are opened at the lower end of the chassis 300. A V-shaped supporting foot 301 is hinged inside each rectangular groove, and a connecting rod 302 is hinged at the corner of each V-shaped supporting foot 301. A pull rod 303 is hinged at the end of each connecting rod 302, and one end of each pull rod 303 extending into the interior of the fuselage 100 is commonly connected to a lifting assembly.

[0044] The lower side of the opposite side of each V-shaped support foot 301 is provided with anti-slip grooves.

[0045] A threaded rod 304 is provided in the middle of the upper end of the fuselage 100 , and a protective cover 305 is threadedly connected to the outer side of the threaded rod 304 . The protective cover 305 covers the upper side of the rubber protective ring 104 , and a rotating piece 306 is provided in the middle of the upper end of the protective cover 305 .

[0046] In this embodiment, the limit block 201 can prevent the n-shaped fixing block 200 from being separated from the T-shaped slot 107, thereby affecting the connection between the rubber protection ring 104 and the mounting block 103, and affecting the protection of the drone;

[0047] By pressing two opposite n-shaped fixing blocks 200 at the same time, the n-shaped fixing blocks 200 can be taken out from the inside of the T-shaped slot 107, so that the rubber protective ring 104 can be quickly removed, which is convenient for repairing or replacing the rubber protective ring 104.

[0048] By relying on the cooperation between the mounting hole 202 and the clamping block 204, the camera 203 can be mounted and fixed, so as to facilitate the maintenance and replacement of the camera 203;

[0049] The cameras 203 are arranged in a ring shape by means of the rubber protective ring 104, so that 360-degree all-round shooting can be performed, thereby obtaining clearer and more accurate data.

[0050] The groove 205 can facilitate the wiring arrangement of the drone, and also facilitate the line connection of the camera 203. During the flight of the drone, each protective rod 206 can prevent the line from sagging, reducing the impact of the external environment on the drone.

[0051] The lifting assembly can drive each pull rod 303 to move up and down, and through the transmission of the connecting rod 302, it can rotate at the hinge point between the V-shaped support foot 301 and the chassis 300;

[0052] Among them, the four rectangular grooves correspond to four V-shaped support feet 301, and the four V-shaped support feet 301 are respectively located at four positions of the chassis 300. When the pull rod 303 rises, the four V-shaped support feet 301 can be driven to flip outward by relying on the connecting rod 302, so that the four V-shaped support feet 301 are in contact with the ground at the same time, thereby achieving support for the drone;

[0053] When the pull rod 303 moves downward, the four V-shaped support legs 301 are turned inward by relying on the connecting rod 302. With the anti-slip grooves on the lower side of the inner wall of each V-shaped support leg 301, objects can be easily grabbed without slipping.

[0054] By twisting the rotating piece 306, the protective cover 305 can be indirectly driven to rotate, so that the protective cover 305 can be removed from the drone;

[0055] The protective cover 305 can protect the rotors 102 and prevent high-altitude debris from falling directly onto the drone, affecting the rotation of the rotors 102 and causing the drone to fall directly and be damaged.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
