Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a collision-preventing unmanned aerial vehicle. BACKGROUND

[0002] An unmanned aerial vehicle is a kind of unmanned aircraft that is controlled by radio remote control equipment and self-provided program control device. It has the advantages of small size, low cost, easy use, and low requirement for the use environment. At present, unmanned aerial vehicles are widely used in many industries such as military, agriculture, forestry, and logistics transportation.

[0003] For example, a kind of explosion-proof unmanned aerial vehicle with the authorization announcement number CN 217706278 U in China discloses an unmanned aerial vehicle capable of improving the detection sensitivity of the unmanned aerial vehicle in the event of a collision accident.

[0004] However, most of the current unmanned aerial vehicles only use a single protective structure to protect the wing assembly when flying in harsh environments, resulting in poor protection effect of the wing assembly, making it vulnerable to damage from collisions. At the same time, the protective structure is mostly fixed and installed in an integrated manner, which is not convenient to disassemble and replace. Content of the utility model

[0005] Therefore, the present application provides a collision-preventing unmanned aerial vehicle to solve the problem of poor protection effect of the wing assembly, making it vulnerable to damage from collisions, and inconvenient to disassemble and replace.

[0006] In order to achieve the above purpose, the present application provides the following technical solutions:

[0007] The collision-preventing unmanned aerial vehicle comprises an unmanned aerial vehicle body, a protective frame, and a mounting column. The left and right ends of the unmanned aerial vehicle body are fixedly installed with mounting frames on the outer sides, and the wing assembly is arranged on the upper side of the end of the mounting frame away from the unmanned aerial vehicle body.

[0008] The outer side of the mounting frame is connected with the protective frame, and the outer side of one end of the protective frame close to the unmanned aerial vehicle body is fixedly installed with a positioning block.

[0009] The inner side of the unmanned aerial vehicle body is rotatably provided with a mounting column, and the inner side of the unmanned aerial vehicle body is provided with an adjusting screw rod on the upper end. The lower end of the adjusting screw rod is fixedly installed with a connecting block on the outer side, and the outer side of the mounting column is integrally fixedly installed with a fixed block. The upper end of the mounting column is provided with a prefabricated groove in the inner side, and the lower end of the connecting block extends into the inner side of the prefabricated groove.

[0010] Further, the side wall of the protective frame is provided with a ventilation hole penetratingly formed in the inner side, and the lower end of the protective frame is arranged in an open manner.

[0011] Furthermore, the positioning block and the protective frame are connected by a plug-in connection, and the interior of the positioning block has a slot-shaped structure that is compatible with the fixing block.

[0012] Furthermore, the fixing block is connected to the positioning block by a plug-in connection through a groove structure.

[0013] Furthermore, the connecting block is connected to the precast groove by a snap-fit ​​method, and the cross-section of the precast groove is "+" shaped.

[0014] Furthermore, tripods are installed on both the lower left and right sides of the drone body.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] 1. The protective frame is set up in a one-to-one correspondence with the wing assembly. Align the positioning block with the limiting groove opened inside the mounting frame, and insert the positioning block into the inside of the mounting frame from top to bottom, so that the protective frame is located on the outside of the wing assembly. This makes it easy to protect the wing assembly through the protective frame and avoid collisions to the wing assembly.

[0017] 2. After the positioning block is fully inserted into the drone body, rotate the adjusting threaded rod to make the adjusting threaded rod threadedly connected to the drone body, and drive the mounting column and fixing block to rotate inside the drone body. As the mounting column rotates, the fixing block can be inserted into the positioning block and mounting frame. At this time, the fixing block plays a good role in fixing the positioning block. When one set of protective frames is deformed due to collision, the above steps can be reversed to disassemble and replace the corresponding protective frame, improving the convenience of use.

[0018] 3. The lower end of the connecting block extends into the interior of the precast groove. The connecting block has a good limiting and transmission function for the adjusting threaded rod. When the adjusting threaded rod rotates, it is convenient to drive the mounting column and the adjusting threaded rod to rotate synchronously through the connecting block and the precast groove.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 4 As shown, the anti-collision drone in the first aspect embodiment of this application includes: drone body 1, protective frame 4 and mounting column 7. Mounting frame 2 is fixedly installed on the outer sides of both the left and right ends of the drone body 1, and a wing assembly 3 is provided on the upper side of the end of the mounting frame 2 away from the drone body 1. Footrests 12 are installed on both the left and right sides of the lower end of the drone body 1. The combination constitutes the drone structure. The mounting frame 2 plays a good role in the installation and support of the wing assembly 3, and at the same time facilitates the subsequent installation of the protective frame 4.

[0028] A protective frame 4 is connected to the outside of the mounting frame 2, and a positioning block 6 is fixedly installed on the outer side of the protective frame 4 near the UAV body 1. The positioning block 6 is connected to the protective frame 4 by a plug-in method. The lower end of the protective frame 4 is open. When installing the protective frame 4, first align the positioning block 6 with the limiting groove opened inside the mounting frame 2, and insert the positioning block 6 into the inside of the mounting frame 2 from top to bottom, so that the protective frame 4 is located on the outside of the wing assembly 3, so that the wing assembly 3 can be protected by the protective frame 4 to avoid the wing assembly 3 from being hit.

[0029] The protective frame 4 has ventilation holes 5 through the inside of its side wall. The ventilation holes 5 can promote airflow and reduce the drag encountered by the whole during flight.

[0030] The drone body 1 has a mounting column 7 inside for rotation, and an adjusting threaded rod 8 is provided on the upper inner side of the drone body 1. A connecting block 9 is fixedly installed on the outer side of the lower end of the adjusting threaded rod 8. A fixing block 11 is integrally fixedly installed on the outer side of the mounting column 7. A groove-shaped structure adapted to the fixing block 11 is opened through the interior of the positioning block 6. The fixing block 11 is connected to the positioning block 6 by plugging in through the groove-shaped structure.

[0031] After the positioning block 6 is fully inserted into the interior of the UAV body 1, rotate the adjusting threaded rod 8 to make the adjusting threaded rod 8 threadedly connected to the UAV body 1, and drive the mounting post 7 and the fixing block 11 to rotate inside the UAV body 1. As the mounting post 7 rotates, the fixing block 11 can be inserted into the interior of the positioning block 6 and the mounting bracket 2. At this time, the fixing block 11 plays a good role in fixing the positioning block 6, which makes it convenient to fix the protective frame 4 to the outside of the wing assembly 3 through the positioning block 6. At the same time, the protective frame 4 and the wing assembly 3 are set in a one-to-one correspondence. When one set of protective frames 4 is deformed due to collision, the above steps can be reversed to disassemble and replace the corresponding protective frame 4, improving the convenience of use.

[0032] The upper end of the mounting column 7 has a prefabricated groove 10, and the lower end of the connecting block 9 extends into the interior of the prefabricated groove 10. The connecting block 9 and the prefabricated groove 10 are connected by a snap-fit ​​method, and the cross-section of the prefabricated groove 10 is "+" shaped. The connecting block 9 has a good limiting and transmission function for the adjusting threaded rod 8. When the adjusting threaded rod 8 rotates, it is convenient to drive the mounting column 7 and the adjusting threaded rod 8 to rotate synchronously through the connecting block 9 and the prefabricated groove 10. There is a certain distance between the lower end of the adjusting threaded rod 8 and the upper end of the mounting column 7. When the adjusting threaded rod 8 moves downward with the UAV body 1, it will not affect the rotation of the mounting column 7.

[0033] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
