Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision structures, in particular to an anti-collision structure for an unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control and self-contained programmable controls. Compared to manned aircraft, UAVs are often better suited for tasks deemed "dull, dirty, or dangerous." Drones can be categorized into military and civilian applications. In the military, UAVs are divided into reconnaissance and target drones. In the civilian sector, the combination of UAVs and industrial applications is a real necessity. Current applications 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 production, and the creation of romance have greatly expanded the uses of UAVs themselves. Developed countries are also actively expanding industrial applications and developing UAV technology.

[0003] Announcement No. "CN118004467A" discloses an anti-collision structure for a UAV, including a UAV body and an anti-collision component. The anti-collision component includes a rotating block, a rotor, a protective block, a detection head, a driving block, a connecting block, a movable block, an anti-collision head and a limit block. By installing or disassembling the anti-collision head, the anti-collision head can be removed when the anti-collision head is damaged, which facilitates the replacement of a new anti-collision head. By setting the anti-collision head, the UAV body can be subjected to anti-collision treatment, thereby avoiding the situation where the UAV loses power and freely falls due to abnormal power supply of the UAV and a serious collision with the ground or other obstacles occurs, thereby avoiding the situation where the UAV is easily damaged due to a serious collision between the UAV and the ground or other obstacles.

[0004] The above-mentioned UAV anti-collision structure mainly enhances the overall anti-collision performance by installing a protective ring on the outside of the UAV. However, in actual application, since the UAV needs to perform multiple actions such as rising, descending and hovering during flight, this design that relies solely on the protective ring on the outside of the blade has limitations. Especially when the UAV is rising or descending, if it encounters an obstacle on the top, it is easy for the UAV to directly contact the obstacle, thereby damaging key components such as the blades. Therefore, relying solely on the protective ring on the outside of the blade cannot achieve comprehensive protection for the UAV. Therefore, this application provides a UAV anti-collision structure to meet the needs. Utility Model Content

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an anti-collision structure for a drone, including a protective ring 1, which is in a circular ring shape. A fixing frame 2 is provided at the inner edge of the protective ring 1, and a connecting rod 3 is symmetrically protruded on the outer side of the fixing frame 2. The connecting rod 3 is fixed to the inner side of the protective ring 1 on a side away from the fixing frame 2, and a bolt hole 4 for installing the drone is provided on the fixing frame 2. Through the cooperation between the protective ring 1 and the fixing frame 2, the overall frame of the drone can be effectively increased when installed with the drone, and the side collision of the drone with obstacles can be better avoided when a novice operates the drone.

[0036] The above-mentioned protective ring 1 is equipped with a fixing component 5 at the top and bottom, and a top plate 15 is installed above and at the bottom of the axial position of the protective ring 1. The top plate 15 is disc-shaped, and a plug-in hole 151 for the elastic fixing rod 16 to be plugged in is provided on the outer edge of the top plate 15. There are several plug-in holes 151, and the several plug-in holes 151 are arranged in a circular array with the center of the top plate 15 as the center. An elastic fixing rod 16 is installed between the top plate 15 and the fixing component 5.

[0037] By cooperating with the protective ring 1 and the fixing frame 2, the top plate 15, the elastic fixing rod 16 and the fixing assembly 5, the overall frame of the drone can be expanded by pre-installing the drone on the fixing frame 2 during operation. The top plate 15, the elastic fixing rod 16 and the fixing assembly 5 are designed to be in a semicircular cover shape after installation, so that the drone can perform various actions such as rising or descending and circling, and can effectively avoid collisions between various positions of the drone and obstacles, and can try to avoid situations such as damage to the propeller blades caused by the drone encountering overhead obstacles. The drone can be fully protected and can be comprehensively protected when novices are learning to use drones.

[0038] like Figure 2 、 Figure 4 and Figure 5 As shown, there are several fixing components 5, and the several fixing components 5 are arranged in a circular array with the center of the protective ring 1 as the center. The fixing component 5 includes a cylindrical mounting shell 6, and the mounting shell 6 is provided with an insertion hole for the elastic fixing rod 16 to penetrate. A plurality of clamping pads 7 are protrudingly provided at the inner edge of the insertion hole. Through the provided clamping pads 7, the elastic fixing rod 16 can be effectively fixed after being inserted into the insertion hole.

[0039] The fixing assembly 5 arranged in a ring array can ensure that a semicircular protective cover can be formed between the plurality of elastic fixing rods 16 and the protective ring 1, thereby effectively protecting the various components of the drone and effectively protecting the drone.

[0040] A mounting hole 91 is drilled on the outer side of the above-mentioned protective ring 1. Several mounting holes 91 are arranged in a circular array on the protective ring 1 with the center of the protective ring 1 as the center. A buffer component 9 for auxiliary buffering is symmetrically installed on the outer side of the protective ring 1. The buffer component 9 includes a buffer cylinder 10. A buffer cavity is opened inside the buffer cylinder 10. A slide rod 13 is slidingly arranged in the buffer cavity. There is a gasket between the slide rod 13 and the inner side edge of the buffer cavity. There is a certain friction between the gasket and the buffer cavity, which can effectively consume the force when the slide rod 13 slides. A buffer spring 12 is installed in the buffer cavity to assist the slide rod 13 in pushing it. A buffer plate 14 is fixed on the side plate of the slide rod 13 away from the buffer spring 12. A threaded mounting column 11 is fixed on the side of the buffer cylinder 10 away from the slide rod 13, and the mounting hole 91 is threadedly matched with the threaded mounting column 11.

[0041] By setting the buffer component 9 on the outer edge of the protective ring 1, when the side encounters a collision, the buffer plate 14 drives the slide bar 13 to move as a whole, and then drives the buffer spring 12 to be compressed as a whole, thereby realizing the overall buffering treatment of the drone, and avoiding hard collisions between the anti-collision structure and obstacles when the side encounters a collision.

[0042] The buffer tube 10 is provided with an outlet for the slide rod 13 to extend out, the buffer plate 14 is an arc-shaped plate structure, and a limiting groove 131 is symmetrically provided on the outer side of the slide rod 13. The buffer tube 10 is symmetrically provided with a limiting block 101 at the outlet corresponding to the slide rod 13, and the limiting block 101 slides in cooperation with the limiting groove 131.

[0043] The cooperation between the limiting block 101 and the limiting groove 131 can ensure that the slide bar 13 can only slide stably laterally, and can avoid the slide bar 13 from rotating during the buffering process as much as possible.

[0044] The working principle of the technical solution provided by the utility model is as follows:

[0045] When the protective ring 1 needs to be installed, the fixing frame 2 is placed at the bottom of the drone, and the bolt holes 4 are aligned with the positioning bolts and the bolts are tightened with a wrench, thereby completing the preliminary positioning and installation of the fixing frame 2.

[0046] When the anti-collision structure needs to be assembled, the threaded mounting column 11 is threadedly installed in the mounting hole 91 to complete the overall positioning and installation processing of the buffer component 9, the fixing column 8 is threadedly installed in the fixing hole to complete the overall installation processing of the fixing component 5, the elastic fixing rod 16 is plugged into the plug hole 151 to complete the preliminary installation of the elastic fixing rod 16, and one end of the elastic fixing rod 16 is plugged into the penetration hole of the mounting shell 6 to complete the overall assembly of the anti-collision structure.

[0047] During operation, the circular shield is formed at the top and bottom to ensure that the top and bottom of the drone are effectively protected, and the blades are prevented from touching the top and causing damage to the blades during the drone's ascent. The buffer assembly 9 is arranged on the side of the protective ring 1, so that when the side encounters an impact, the buffer plate 14 drives the slide bar 13 to move as a whole, and then drives the buffer spring 12 to be compressed as a whole, thereby realizing the overall buffering treatment of the drone.

[0048] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
