[0002] Unmanned aerial vehicle, referred to as "drone", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer. The current application of drones in aerial photography, agriculture, plant protection, news reporting, disaster relief and other fields has greatly expanded the use of drones themselves. Drones are sought after by more and more people for their simple structure, convenient control and high safety.

[0003] Announcement No. CN 215323290 U discloses a wing protection structure for an unmanned aerial vehicle. By setting a protection device, the side of the propeller can be protected by a protection ring, and the top of the propeller can be protected by a protection plate, so that the propeller can be fully protected, and the protection effect of the wing is effectively enhanced. By setting a fixing device and a mounting device, the stability of the mounting block is enhanced by a reinforcement rod and a stabilizing rod, thereby improving the stability of the protective cover. The protective cover can be removed from the fixing block by tightening the bolts, and the fixing plate can be removed from the fixing seat by loosening the screws, thereby facilitating the removal and replacement of the protective cover, and improving the practicality of the device.

[0004] However, there are some defects in the above scheme: although a protective ring is provided for protection in the above scheme, the protective ring is easily damaged by collision and has poor durability. In addition, the protective cover is installed and fixed by multiple bolts, which greatly affects the efficiency of disassembly and assembly of the protective cover and reduces its practicality.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with 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 of the embodiments.

[0030] See also Figure 1-Figure 5 The present application provides a drone with a protective structure, including a drone component 100 and a protective component 200.

[0031] See also Figure 1 and 2 The drone assembly 100 includes a drone body 110 , a support arm 120 and an electric rotor 130 . The support arm 120 is disposed on one side of the drone body 110 , and the electric rotor 130 is installed at the end of the support arm 120 .

[0032] In a specific implementation scheme, a support leg 140 is provided at the bottom of the drone body 110, and a rubber pad is provided at the bottom of the support leg 140. By providing the rubber pad at the bottom of the support leg 140, the friction with the ground is increased and wear is reduced.

[0033] See also Figure 1 , 2 , 3, 4 and 5, the protection assembly 200 includes a fixed block 210, a protection ring 220, a fixing member 230, a spring sheet 240, a protection cover 250 and a hook 270, the fixed block 210 is fixedly connected to the support arm 120, the protection ring 220 is sleeved on the outside of the electric rotor 130, and the protection ring 220 is connected to the fixed block 210 through the fixing member 230, the spring sheet 240 is arranged on the outside of the protection ring 220, the hook 270 is arranged at the bottom of the protection cover 250, and the hook 270 abuts against the bottom of the protection ring 220.

[0034] Among them, the fixed block 210 is provided with a slot 211, the protective ring 220 is provided with a break and is fixedly connected with an insert block 222, the insert block 222 is inserted into the slot 211, and the fixing piece 230 is crimped on the top of the insert block 222. By setting the insert block 222 to be inserted into the slot 211, the protective ring 220 can be pre-installed and connected to the fixed block 210, and then fixed with the fixing piece 230.

[0035] It should be noted that the slot 211 and the plug-in block 222 are both T-shaped. By providing the T-shaped slot 211 and the plug-in block 222, a stable plug-in connection between the plug-in block 222 and the slot 211 can be achieved to prevent disengagement.

[0036] In this embodiment, the fixing member 230 includes a pressing plate 231 and a fixing bolt 232. The fixing bolt 232 passes through the pressing plate 231. The fixing bolt 232 is threadedly connected to the fixing block 210. The pressing plate 231 is pressed on the top of the insert block 222. By setting the pressing plate 231 and the fixing bolt 232, the fixing bolt 232 is rotated to pass through the pressing plate 231, and the fixing bolt 232 is threadedly connected to the fixing block 210.

[0037] The top of the protective cover 250 is arched, and the protective cover 250 is provided with a plurality of ventilation holes 251. The protective cover 250 with an arched top is used to block debris, and the plurality of ventilation holes 251 are used for air flow.

[0038] In a specific implementation, the protective cover 250 is provided with a positioning opening 252, which is sleeved on the outside of the fixing block 210. The positioning opening 252 is used to position the installation of the protective cover 250, and the protective cover 250 is stably installed in the protective ring 220 in cooperation with the hook 270.

[0039] It should be noted that the electric rotor 130 is driven by a motor to rotate the rotor, and the UAV body 110 and the electric rotor 130 are conventional prior art and well known to those skilled in the art, and will not be described in detail here.

[0040] The working principle of the drone with a protective structure is as follows: during use, the electric rotor 130 rotates at high speed to drive the entire drone to take off, and the protective ring 220 protects the outer side of the electric rotor 130. When an accidental collision occurs, the spring sheet 240 contacts the collision object, and the elastic effect of the spring sheet 240 is used to buffer the collision, which greatly reduces the damage caused by the collision force and improves the protection and durability. The protective cover 250 with a plurality of vents 251 can ensure air flow and the airflow lift required by the electric rotor 130. When disassembly, maintenance, repair or replacement is required, the protective cover 250 can be rotated. Remove the fixing bolts 232, and then remove the pressure plate 231, and the protective ring 220 and the plug block 222 can be removed from the fixing block 210, avoiding the installation method of multiple bolts, greatly improving the disassembly efficiency, and similarly, the installation is more efficient. Further, it is necessary to replace the protective cover 250 separately, push the bottom end of the hook 270 to bend, and the protective cover 250 can be pulled out of the protective ring 220. When installing, just press it into the protective ring 220. The positioning port 252 on the protective ring 220 cooperates with the hook 270 to stably install the protective cover 250 in the protective ring 220.

[0041] It should be noted that the specific model specifications of the drone body 110 and the electric rotor 130 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] The power supply and principle of the drone body 110 and the electric rotor 130 are clear to those skilled in the art and will not be described in detail here.

[0043] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
