Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle technology, and in particular to a drone protective cover and a drone system having the drone protective cover. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are a general term for unmanned aerial vehicles that are controlled by radio remote control equipment and onboard program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. Compared to manned aircraft, UAVs have advantages such as small size, low cost, and ease of use, and are widely used in both military and civilian applications. In civilian applications, UAVs are used in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romantic scenes, greatly expanding the application areas of UAVs.

[0003] With the increasing demand for drones in complex environments, such as confined spaces like pipes, chimneys, and alleyways, drones are more susceptible to collisions with walls, objects, and obstacles while flying in such confined spaces, or even crashes due to malfunctions. To prevent collision damage and improve drone safety, environmental adaptability, and mission reliability, protective shields are typically added to drones. These shields protect the drone from collisions, especially the propellers, a core component of the drone's propulsion system.

[0004] However, the existing protective cover is composed of components connected by bolts and nuts, resulting in a heavy cover that increases the overall weight of the drone. Furthermore, assembling these components is cumbersome, time-consuming, and labor-intensive. Additionally, the existing protective cover is installed on the drone using multiple sets of bolts, making removal and reassembly cumbersome, time-consuming, and unable to achieve rapid assembly and disassembly. Utility Model Content

[0005] The primary objective of this invention is to provide a drone protective cover that is simple and quick to assemble and disassemble, lightweight, and structurally strong, thereby enabling rapid assembly and disassembly response.

[0006] The second objective of this invention is to provide a drone system with the aforementioned drone protective cover.

[0007] To achieve the primary objective of this utility model, a protective cover for a drone is provided, comprising an upper ring, a middle ring, a lower ring, multiple protective strips, and two hollow carbon tubes. The upper ring is vertically positioned above the lower ring, and the middle ring is vertically positioned between the upper and lower rings. The diameters of both the upper and lower rings are smaller than the diameter of the middle ring. The multiple protective strips are evenly arranged around the circumference of the middle ring to form a protective space. The upper ends of the protective strips are detachably and elastically engaged with the upper ring. The middle buckle of the strip is detachably and elastically engaged with the middle ring, and the lower end buckle of the protective strip is detachably and elastically engaged with the lower ring. Two of the protective strips, which are arranged radially opposite to each other in the middle ring, are each provided with a locking sleeve. The first end of a hollow carbon tube is detachably inserted into the locking sleeve, so that the two hollow carbon tubes are arranged radially opposite to each other in the protective space. The second end of each hollow carbon tube is provided with a disassembly structure, which is used to detachably connect to the mounting bracket on the drone. The drone's propeller is located in the protective space.

[0008] As can be seen from the above scheme, during the assembly of the UAV protective cover of this utility model, each protective strip is elastically engaged with the upper, middle, and lower rings respectively through the upper, middle, and lower buckles. Thus, multiple protective strips support the upper, middle, and lower rings and form a protective space. Next, the first ends of two hollow carbon tubes are respectively inserted into the engaging sleeves of two oppositely arranged protective strips. Subsequently, the second end of the hollow carbon tubes is connected to the hanger on the UAV through the disassembly and assembly structure, so that the UAV's propeller is located within the protective space, thereby providing collision protection for the UAV and propeller, and improving the safety, environmental adaptability, and mission reliability of the UAV.

[0009] Therefore, the assembly of the drone protective cover of this utility model does not require any tools, and the assembly operation is simple and quick. In addition, compared with the existing protective covers where the related components are connected by bolts and nuts, the drone protective cover of this utility model is connected by snap-fit ​​elastic engagement and snap-fit ​​sleeve engagement, which reduces the weight of complex connection structures and can reduce the weight of the drone protective cover.

[0010] Furthermore, this utility model's drone protective cover can be disassembled into individual parts: an upper ring, a middle ring, a lower ring, multiple protective strips, and two hollow carbon tubes, reducing its volume during transportation or storage. Simultaneously, the upper, middle, and lower rings, multiple protective strips, and two hollow carbon tubes of this utility model's drone protective cover can be assembled like building blocks; only the damaged part needs to be replaced, instead of discarding the entire cover, thus reducing repair costs. Moreover, the disassembly and assembly structure of this utility model's drone protective cover allows for quick disassembly and assembly with the drone's mounting bracket, significantly reducing the time required for disassembly and assembly between the drone and the protective cover, thereby achieving rapid response.

[0011] In addition, the multiple protective strips of the drone protective cover of this utility model are evenly arranged around the central ring to form a protective space, and the protective strips are elastically engaged with the upper ring, the middle ring and the lower ring respectively by the upper buckle, the middle buckle and the lower buckle, thereby enhancing the structural strength of the drone protective cover.

[0012] Therefore, the drone protective cover of this utility model is lightweight, has high structural strength, and is simple and quick to assemble and disassemble, thus achieving rapid assembly and disassembly response.

[0016] A further proposed solution is to have a mounting sleeve protruding from the side of the mounting base away from the side cover, into which the second end of the hollow carbon tube can be detachably inserted.

[0017] A further improvement is that the drone protective cover also includes two upper inclined bracing structures, which are radially opposite each other in the middle ring. Each upper inclined bracing structure includes an upper connector and two upper support rods. The upper connector includes an upper ring and two upper inclined sleeves. The upper ring is detachably fitted onto the hollow carbon tube. The two upper inclined sleeves are connected to the upper ring in a V-shape towards the upper ring.

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0040] See Figures 1 to 13 This embodiment discloses an unmanned aerial vehicle (UAV) system 10, including a UAV 12 and a UAV protective cover 11.

[0041] In this embodiment, the drone 12 is provided with mounting brackets 123 on opposite sides, and the drone protective cover 11 includes an upper ring 111, a middle ring 113 and a lower ring 112. The upper ring 111 is located above the lower ring 112 in the vertical direction, and the middle ring 113 is located between the upper ring 111 and the lower ring 112 in the vertical direction. The diameters of the upper ring 111 and the lower ring 112 are both smaller than the diameter of the middle ring 113.

[0042] Furthermore, the drone protective cover 11 in this embodiment also includes multiple protective strips 115 and two hollow carbon tubes 116. The multiple protective strips 115 are evenly arranged around the central ring 113 to form a protective space (not shown). The upper end buckle 1151 of the protective strip 115 is detachably and elastically engaged with the upper end ring 111, the middle buckle 1153 of the protective strip 115 is detachably and elastically engaged with the middle ring 113, and the lower end buckle 1152 of the protective strip 115 is detachably and elastically engaged with the lower end ring 112.

[0043] Furthermore, two of the protective strips 115 arranged radially opposite to each other in the middle ring 113 are respectively provided with locking sleeves 1155. The first end of a hollow carbon tube 116 is detachably inserted into the locking sleeve 1155, so that the two hollow carbon tubes 116 are arranged radially opposite to each other in the protective space of the middle ring 113. The second end of each hollow carbon tube 116 is provided with a disassembly structure 117. The disassembly structure 117 is used to detachably connect to the mounting bracket 123 on the UAV 12. The propeller 121 of the UAV 12 is located in the protective space surrounded by the upper ring 111, the middle ring 113, the lower ring 112 and the multiple protective strips 115.

[0044] In this embodiment, during the assembly of the drone protective cover 11, each protective strip 115 is elastically engaged with the upper ring 111, middle ring 113, and lower ring 112 respectively via the upper buckle 1151, middle buckle 1153, and lower buckle 1152. Thus, multiple protective strips 115 support the upper ring 111, middle ring 113, and lower ring 112 and form a protective space. Next, the first ends of two hollow carbon tubes 116 are respectively inserted into the engaging sleeves 1155 of two oppositely arranged protective strips 115. Subsequently, the second end of the hollow carbon tube 116 is connected to the mounting bracket 123 on the drone 12 via the disassembly and assembly structure 117 on the second end of the hollow carbon tube 116, so that the propeller 121 of the drone 12 is located within the protective space, thereby providing anti-collision protection for the drone 12 and the propeller 121, thereby improving the safety, environmental adaptability, and mission reliability of the drone 12.

[0045] Therefore, the assembly of the drone protective cover 11 in this embodiment does not require any tools, and the assembly operation is simple and quick. In addition, compared with the existing protective covers where the relevant components are connected by bolts and nuts, the drone protective cover 11 in this embodiment is connected by snap-fit ​​elastic engagement and snap-fit ​​sleeve 1155, which reduces the weight of complex connection structure and can reduce the weight of the drone protective cover 11.

[0046] Furthermore, the drone protective cover 11 in this embodiment can be disassembled into individual parts: an upper ring 111, a middle ring 113, a lower ring 112, multiple protective strips 115, and two hollow carbon tubes 116, thus reducing the transport volume during transportation or storage. Simultaneously, the upper ring 111, middle ring 113, lower ring 112, multiple protective strips 115, and two hollow carbon tubes 116 of the drone protective cover 11 in this embodiment can be assembled like building blocks; only the damaged parts need to be replaced, instead of discarding the entire cover, reducing maintenance costs. Moreover, the disassembly and assembly structure 117 of the drone protective cover 11 in this embodiment allows for quick disassembly and assembly with the mounting bracket 123 on the drone 12, significantly reducing the disassembly and assembly time between the drone protective cover 11 and the drone 12, thereby achieving rapid disassembly and assembly response.

[0047] In addition, in this embodiment, the multiple protective strips 115 of the drone protective cover 11 are evenly arranged around the central ring 113 to form a protective space, and the protective strips 115 are elastically engaged with the upper ring 111, the middle ring 113 and the lower ring 112 respectively by the upper buckle 1151, the middle buckle 1153 and the lower buckle 1152, thereby enhancing the structural strength of the drone protective cover 11.

[0048] Therefore, the drone protective cover 11 in this embodiment is lightweight, has high structural strength, and is simple and quick to assemble and disassemble, thus achieving rapid assembly and disassembly response.

[0049] To further improve the structural strength of the outer frame of the drone protective cover 11, the drone protective cover 11 in this embodiment also includes two transition rings 114. One transition ring 114 is located vertically between the upper ring 111 and the middle ring 113, and the other transition ring 114 is located vertically between the lower ring 112 and the middle ring 113. The two transition rings 114 are symmetrically arranged about the middle ring 113. The two transition buckles 1154 of each protective strip 115 are detachably and elastically engaged with the two transition rings 114. In this embodiment, the diameter of the transition ring 114 is smaller than the diameter of the middle ring 113, and the diameter of the transition ring 114 is larger than the diameter of the upper ring 111 and the diameter of the lower ring 112.

[0050] Combination Figure 12In this embodiment, the diameter of the locking hole 11531 of the central buckle 1153 on the protective strip 115 is slightly smaller than the diameter of the central ring 113, and the width of the locking opening 11532 of the central buckle 1153 on the protective strip 115 is smaller than the diameter of the central ring 113. This allows the central buckle 1153 on the protective strip 115 to elastically engage with the central ring 113, relying on the frictional force generated by the elastic deformation of the central buckle 1153 to securely fasten the central ring 113 to the protective strip 115. Correspondingly, the elastic engagement method of the upper buckle 1151, lower buckle 1152, and transition buckle 1154 on the protective strip 115 in this embodiment is the same as that of the central buckle 1153.

[0051] To further improve the structural strength of the protective strip 115, in this embodiment, a first reinforcing rib 1156 protrudes from the center of the circumferential direction of the central ring 113. The first reinforcing rib 1156 connects the upper buckle 1151 and the transition buckle 1154 near the upper buckle 1151. Furthermore, in this embodiment, a second reinforcing rib 1157 protrudes from the center of the circumferential direction of the central ring 113. The second reinforcing rib 1157 connects the central buckle 1153 and the transition buckle 1154 near the upper buckle 1151. Between the buckles 1154, and in this embodiment, the protective strip 115 has a third reinforcing rib 1158 protruding from the center of the circumferential direction of the central ring 113. The third reinforcing rib 1158 connects between the central buckle 1153 and the transition buckle 1154 near the lower buckle 1152. In this embodiment, the protective strip 115 has a fourth reinforcing rib 1159 protruding from the center of the circumferential direction of the central ring 113. The fourth reinforcing rib 1159 connects between the lower buckle 1152 and the transition buckle 1154 near the lower buckle 1152.

[0052] To further improve the structural strength of the hollow carbon nanotube 116 and enhance the connection stability between the disassembly and assembly structure 117 of the hollow carbon nanotube 116 and the mounting bracket 123 on the UAV 12, the UAV protective cover 11 in this embodiment also includes two upper inclined bracing structures. The two upper inclined bracing structures are arranged radially opposite each other in the middle ring 113. Each upper inclined bracing structure includes an upper connector (not shown) and two upper support rods (not shown). The upper connector includes an upper ring sleeve and two upper inclined sleeves. The upper ring sleeve is detachably fitted onto the hollow carbon nanotube 116. The two upper inclined sleeves are connected to the upper ring sleeve in a V-shape facing the upper ring 111. The first ends of the two upper support rods are detachably inserted into the two upper inclined sleeves, and the second ends of the two upper support rods are respectively hinged to the upper ring 111, so that the two upper support rods are arranged in a V-shape facing the upper ring 111. And / or, the UAV protective cover 11 in this embodiment also includes two lower inclined bracing structures. The support structure consists of two lower inclined support structures arranged radially opposite each other in the middle ring 113. Each lower inclined support structure includes a lower connector 1182 and two lower support rods 1181. The lower connector 1182 includes a lower ring sleeve 11821 and two lower inclined sleeves 11822. The lower ring sleeve 11821 is detachably fitted onto the hollow carbon tube 116. The two lower inclined sleeves 11822 are connected to the lower ring sleeve 11821 in a V-shape facing the lower end ring 112. The first ends of the two lower support rods 1181 are detachably inserted into the two lower inclined sleeves 11822, and the second ends of the two lower support rods 1181 are respectively hinged to the lower end ring 112, so that the two lower support rods 1181 are V-shaped facing the lower end ring 112. This improves the structural support strength of the hollow carbon tube 116 of the UAV protective cover 11, so that the hollow carbon tube 116 of the UAV protective cover 11 can stably support the UAV 12.

[0053] See Figures 14 to 17In this embodiment, the disassembly and assembly structure 117 includes a mounting base 1171, a side cover 1172, a locking element 1173, and a spring 1174. The mounting base 1171 is disposed at the second end of the hollow carbon tube 116. The side cover 1172 covers the side of the mounting base 1171 away from the hollow carbon tube 116 and forms an internal cavity (not shown) with the mounting base 1171. A first through groove 11721 is provided on the outer side of the side cover 1172 away from the mounting base 1171, and the upper end of the side cover 1172 passes through... A second through slot 11722 is provided. A locking member 1173 is movably located within the built-in cavity formed between the side cover seat 1172 and the mounting seat 1171. The locking part 11731 of the locking member 1173 extends out of the second through slot 11722, and the protruding part 11732 of the locking member 1173 extends out of the first through slot 11721 and engages with the engaging groove 1231 of the hanger seat 123. A spring 1174 is located within the built-in cavity and presses against the locking member 1173 and the mounting seat 1171. Therefore, when the drone 12 needs to have a drone protective cover 11 installed, the protruding part 11732 of the locking member 1173, under the elastic restoring force of the spring 1174, extends out of the first through slot 11721 of the side cover seat 1172 and engages with the engaging groove 1231 of the hanger seat 123 of the drone 12, thus connecting the drone protective cover 11 to the drone 12.

[0054] Specifically, in this embodiment, the mounting base 123 of the drone 12 is provided with a limiting groove 1232, which extends in the vertical direction. The side cover 1172 of the detachable structure 117 of the drone protective cover 11 is provided with a limiting plate 11724 on the outside, which is detachably inserted into the limiting groove 1232. Therefore, when the drone 12 needs to have its protective cover 11 installed, the operator presses the locking part 11731 of the locking member 1173, causing the protruding part 11732 of the locking member 1173 to retract into the internal cavity formed by the side cover seat 1172 and the mounting seat 1171. At this time, the spring 1174 located between the locking member 1173 and the mounting seat 1171 is in a compressed state, which inserts the limiting plate 11724 on the side cover seat 1172 into the limiting groove 1232 on the hanging support seat 123. The limiting groove 1232 limits the limiting plate 11724. Then, the operator releases the locking part 11731 of the locking member 1173, and the protruding part 1173 of the locking member 1173 retracts. 2. Under the elastic restoring force of the spring 1174, the first through groove 11721 of the side cover seat 1172 extends and engages with the fastening groove 1231 of the hanger seat 123 of the drone 12, thus connecting the drone protective cover 11 with the drone 12. When it is necessary to remove the drone protective cover 11 from the drone 12, the operator presses the fastening part 11731 of the locking member 1173, causing the protruding part 11732 of the locking member 1173 to retract into the built-in cavity formed by the side cover seat 1172 and the mounting seat 1171. Then, the limiting plate 11724 on the side cover seat 1172 is pulled out from the limiting groove 1232 on the hanger seat 123, thus separating the drone protective cover 11 from the drone 12. It can be seen that the disassembly and assembly operation of the drone protective cover 11 and the drone 12 in this embodiment is simple and quick, thereby achieving rapid disassembly and assembly response.

[0055] To improve the stability and reliability of the movement of the locking component 1173, the locking component 1173 in this embodiment is provided with a slide rail 11733. The slide rail 11733 extends in the moving direction of the locking component 1173. The mounting base 1171 is provided with a first slide groove 11713, and the side cover base 1172 is provided with a second slide groove 11723. The first end of the slide rail 11733 is slidably located in the first slide groove 11713, and the second end of the slide rail 11733 is slidably located in the second slide groove 11723.

[0056] To improve the assembly accuracy between the mounting base 1171 and the side cover 1172, in this embodiment, the mounting base 1171 is provided with a positioning post 11712, and the side cover 1172 is provided with a positioning hole 11726. The positioning post 11712 extends in the moving direction of the locking member 1173 and is detachably inserted into the positioning hole 11726. Furthermore, in this embodiment, a positioning plate 11725 protrudes from the lower end of the side cover 1172, and a positioning groove 11715 is formed through the lower end of the mounting base 1171. The positioning plate 11725 is detachably inserted into the positioning groove 11715. Specifically, in this embodiment, a mounting sleeve 11711 protrudes from the side of the mounting base 1171 away from the side cover 1172, and the second end of the hollow carbon tube 116 is detachably inserted into the mounting sleeve 11711, thus forming a detachable connection between the mounting base 1171 and the hollow carbon tube 116.

[0057] In order to improve the working stability and reliability of the spring 1174, in this embodiment, the locking member 1173 is provided with a first limiting hole 11734 on the side near the mounting base 1171, and the mounting base 1171 is provided with a second limiting hole 11714 on the side near the locking member 1173. The two ends of the spring 1174 are respectively located in the first limiting hole 11734 and the second limiting hole 11714.
