Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) equipment technology, and more specifically, to a UAV robotic arm deployment assembly. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. UAVs are actually a general term for unmanned aircraft. Compared with manned aircraft, they have advantages such as small size, low cost and ease of use.

[0003] However, some existing drone devices are too large and inconvenient to store. If a drone cannot be folded or stored, users may face difficulties when carrying it out. Large, bulky drones often require additional storage space, which may increase the burden on users. Furthermore, drones need to be stored when not in use, and if they are large or have an inconvenient shape, they may take up too much space, causing inconvenience to users, especially those who use drones frequently. The inability to conveniently store drones may affect the daily user experience.

[0004] To address the aforementioned issues, this application provides a drone robotic arm deployment assembly. Utility Model Content

[0005] One objective of this application is to provide a drone robotic arm deployment assembly, comprising a drone body, a groove at the bottom of the drone body, connecting holes at the four corners of the inner wall of the groove, two fixing plates symmetrically fixedly connected to the four corners of the drone body, a shaft rotatably connected between the two fixing plates, a driven wheel and a robotic arm fixedly connected to the outer side of the shaft, four mounting plates fixedly connected to the inner wall of the groove, a rotating rod rotatably connected between the mounting plates and the inner wall of the groove, driven wheels four, three, and two sequentially fixedly connected to the outer side of the rotating rod from top to bottom, a rotating shaft rotatably connected to the middle of the inner wall of the groove, a driving wheel fixedly connected to the outer side of the rotating shaft, a fixing assembly provided on the outer side of the rotating shaft, two threaded grooves formed in the inner wall of the groove, a transmission belt one disposed inside the connecting holes, and transmission belts four, three, and two disposed inside the groove.

[0006] Furthermore, the transmission belt is set on the outside of driven wheel one and driven wheel two. There are two transmission belts in total, and the transmission belt two is set on the outside of two adjacent driven wheels three.

[0007] Furthermore, the transmission belt four is sleeved on the outside of one of the driven pulleys four and the driving pulley, and the transmission belt three is sleeved on the outside of two adjacent driven pulleys four. Both the transmission belt four and the transmission belt three are located below the transmission belt two.

[0008] Furthermore, the fixing component includes a rotating plate and a fixing bolt. The rotating plate is fixedly connected to the outside of the rotating shaft. An insertion hole is provided on the rotating plate, and a fixing bolt is inserted into the insertion hole.

[0009] Furthermore, the fixing bolt is threaded into the inside of the threaded groove, and the rotating plate is located between the inner wall of the groove and the drive wheel.

[0010] Furthermore, a cover plate is provided on the lower inner side of the groove, and the bottom of the cover plate is at the same level as the bottom of the drone body.

[0011] The beneficial effects of this application are:

[0012] Release the fixing of the rotating plate, causing it to rotate. The rotation of the rotating plate causes the rotating shaft to rotate, which in turn causes the drive wheel and transmission belt four to rotate. In conjunction with the four driven wheels three, four driven wheels four, two transmission belts two, and one transmission belt three, the four rotating rods rotate. The rotation of the rotating rods causes driven wheels two and transmission belt one to rotate, which in turn causes driven wheels one and the shaft to rotate, thereby causing the four robotic arms to rotate simultaneously. This allows the four robotic arms to rotate to the four sides of the drone body, and then the robotic arms are fixed. This folding method reduces the size of the drone body, making it easier to store and transport. Attached Figure Description

[0024] Example:

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This application discloses a drone robotic arm deployment assembly, including a drone body 1. The bottom of the drone body 1 has a groove 20. The inner wall of the groove 20 has four corners with connecting holes 3. The connecting holes 3 are connected to the groove 20. Two fixing plates 4 are symmetrically fixed to the four corners of the drone body 1. A shaft is rotatably connected between the two fixing plates 4. Two driven wheels 6 and a robotic arm 2 are fixedly connected to the outer side of the shaft. The robotic arm 2 is disposed between the two driven wheels 6. Four mounting plates 16 are fixedly connected to the inner wall of the groove 20. A rotating rod 15 is rotatably connected between the mounting plates 16 and the inner wall of the groove 20. Driven wheels 10, 9, and 7 are fixedly connected from top to bottom to the outer side of the rotating rod 15. A rotating shaft 17 is rotatably connected to the middle of the inner wall of the groove 20. A drive wheel 14 is fixedly connected to the outer side of the rotating shaft 17.

[0026] A fixing component is provided on the outer side of the rotating shaft 17. Two threaded grooves 21 are opened on the inner wall of the groove 20. A transmission belt 5 is provided inside the connecting hole 3. A transmission belt 13, a transmission belt 11 and a transmission belt 8 are provided inside the groove 20. The transmission belt 5 is sleeved on the outer side of the driven wheel 6 and the driven wheel 7. There are two transmission belts 28. The transmission belt 28 is sleeved on the outer side of two adjacent driven wheels 9. The transmission belt 13 is sleeved on the outer side of one of the driven wheels 10 and the driving wheel 14. The transmission belt 11 is sleeved on the outer side of two adjacent driven wheels 10. The transmission belt 13 and the transmission belt 11 are both located below the transmission belt 8.

[0027] Release the fixing of the rotating plate 18, and then drive the rotating plate 18 to rotate. The rotation of the rotating plate 18 drives the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 drives the driving wheel 14 and the transmission belt 13 to rotate. With the action of the four driven wheels 9, four driven wheels 10, two transmission belts 8 and one transmission belt 11, the four rotating rods 15 are rotated. The rotation of the rotating rods 15 drives the driven wheel 7 and the transmission belt 5 to rotate. The rotation of the transmission belt 5 drives the driven wheel 6 and the shaft to rotate, which in turn drives the four robotic arms 2 to rotate.

[0028] Please see Figure 3 and Figure 4 The fixing assembly includes a rotating plate 18 and a fixing bolt 19. The rotating plate 18 is fixedly connected to the outside of the rotating shaft 17. The rotating plate 18 has an insertion hole, and the fixing bolt 19 is inserted into the insertion hole. The fixing bolt 19 is threaded into the inside of the threaded groove 21. The rotating plate 18 is located between the inner wall of the groove 20 and the drive wheel 14. The fixing bolt 19 is threaded into the inside of the threaded groove 21 to facilitate the fixing of the rotating plate 18, thereby facilitating the fixing of the robotic arm 2.

[0029] Please see Figure 2A cover plate 12 is provided on the lower side of the inside of the groove 20. The cover plate 12 serves to protect the components inside the groove 20. The bottom of the cover plate 12 is at the same level as the bottom of the drone body 1. The cover plate 12 and the drone body 1 are fixed by a snap fastener. Releasing the snap fastener makes it easy to remove the cover plate 12 from the inside of the groove 20, thereby facilitating the operation of the fixing bolt 19 or the maintenance of the inside of the groove 20.

[0030] The implementation principle of this application embodiment is as follows: When it is necessary to store the drone body 1, the fixing bolt 19 is unscrewed from the inside of the threaded groove 21, thereby releasing the fixing of the rotating plate 18, and then driving the rotating plate 18 to rotate. The rotation of the rotating plate 18 drives the rotating shaft 17 to rotate, and the rotation of the rotating shaft 17 drives the driving wheel 14 and the transmission belt 13 to rotate. With the action of the four driven wheels 9, four driven wheels 10, two transmission belts 8 and one transmission belt 11, the four rotating rods 15 rotate. The rotation of the rotating rods 15 drives the driven wheel 7 and the transmission belt 5 to rotate. The rotation of the transmission belt 5 drives the driven wheel 6 and the shaft to rotate, thereby driving the four robotic arms 2 to rotate simultaneously, so that the four robotic arms 2 rotate to the four sides of the drone body 1 respectively. Then, the fixing bolt 19 is threaded into the inside of the corresponding threaded groove 21 to fix the robotic arm 2. This folding method reduces the volume of the drone body 1 and facilitates storage.

[0031] When needed, the rotating plate 18 is released from its fixed position, and the rotating plate 18 is rotated in the opposite direction to unfold the four robotic arms 2 and then fixed.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
