Description

Technical Field

[0001] This invention relates to the technical field of unmanned aerial vehicles (UAVs), and particularly to a pod shock absorption structure and an UAV. Background Technology

[0002] Existing pod vibration damping structures mostly involve setting multiple vertical damping balls between the pod's load-bearing plate and the fuselage connecting plate. For example, a Chinese patent with publication number CN205480075U uses multiple vertical damping balls to reduce the pod's vertical vibration. However, because this structure can only reduce vertical impact, it suffers from a single damping function and poor damping effect, resulting in insufficient pod stability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The primary objective is to provide a pod shock absorption structure with good shock absorption effect and improved pod stability.

[0004] The second objective of this invention is to provide a drone with good shock absorption and improved pod stability.

[0005] The technical solution adopted in this invention is as follows: the pod vibration damping structure includes a pod mounting platform, on which a pod is mounted. The pod mounting platform includes a primary vibration damping mechanism, which includes a primary vibration damping base frame and a primary vibration damping mounting frame. The primary vibration damping mounting frame is located above the primary vibration damping base frame. Multiple vibration damping ball mounting frames are obliquely arranged between the primary vibration damping mounting frame and the primary vibration damping base frame, and each of the multiple vibration damping ball mounting frames is provided with vibration damping balls.

[0006] Furthermore, the pod mounting platform also includes a secondary damping mechanism mounted on the primary damping mechanism. The secondary damping mechanism includes a secondary damping mounting frame, a fuselage connecting plate, and two secondary damping arms. The secondary damping mounting frame is arranged opposite to the fuselage connecting plate. One end of each of the two secondary damping arms is connected to the secondary damping mounting frame, and the other end is connected to the lower part of the fuselage connecting plate through a secondary damping column. A secondary damping buckle is connected between the upper part of the fuselage connecting plate and the secondary damping mounting frame.

[0007] Furthermore, both of the secondary shock absorber arms are connected to the primary shock absorber base frame. The primary shock absorber base frame, the secondary shock absorber mounting frame, and the two secondary shock absorber arms form a lever structure, with the connection point between the two secondary shock absorber arms and the primary shock absorber base frame serving as the fulcrum.

[0008] Furthermore, the two secondary damping columns are located near the fulcrum.

[0009] Furthermore, the secondary shock absorber includes a first fastener, a second fastener, and a shock absorber column. The first fastener is connected to the secondary shock absorber mounting bracket, with its opening facing the bracket. The second fastener is connected to the body connecting plate, with its opening facing the plate. The openings of the first and second fasteners engage. The shock absorber column is connected between the first and second fasteners.

[0010] Furthermore, the bottom of the pod mounting platform is connected to the pod via a pod connecting part, and the pod mounting platform is also provided with an unlocking mechanism for unlocking the pod.

[0011] Furthermore, the unlocking mechanism includes a lever bracket, on which a lever is rotatably connected. One end of the lever has a toggle part, and the other end has a trigger end. An unlocking trigger switch is provided on the pod mounting platform. When the toggle part is toggleed, the trigger end triggers the unlocking trigger switch to unlock.

[0012] Furthermore, a limit feedback protrusion is provided on the lever bracket, and the lever is limited by the limit feedback protrusion when the unlocking trigger switch is triggered at the trigger end.

[0013] Furthermore, multiple shock-absorbing balls are arranged around the primary shock-absorbing mounting frame.

[0014] In addition, the present invention also provides a drone, which includes a main body and a pod shock absorption structure, wherein the main body is connected to the fuselage connecting plate.

[0015] The beneficial effects of this invention are:

[0016] In contrast to the shortcomings of existing technologies, this invention provides multiple shock-absorbing ball mounting frames that are inclinedly arranged between the primary shock-absorbing mounting frame and the primary shock-absorbing base frame. This allows the multiple shock-absorbing balls located on the multiple shock-absorbing ball mounting frames to provide cushioning when subjected to impacts in the vertical and horizontal directions, thus giving the pod shock-absorbing structure the advantages of good shock absorption and improved pod stability.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

When the combination of technical solutions is contradictory or impossible to implement, the user should consider such a combination of technical solutions to be non-existent and not within the scope of protection claimed by this invention.

[0031] like Figures 1 to 5 As shown, in this embodiment, the pod vibration damping structure includes a pod mounting platform 1, on which a pod 2 is mounted. The pod mounting platform 1 includes a primary vibration damping mechanism 3, which includes a primary vibration damping base frame 5 and a primary vibration damping mounting frame 6. The primary vibration damping mounting frame 6 is located above the primary vibration damping base frame 5. Multiple vibration damping ball mounting frames 7 are inclinedly arranged between the primary vibration damping mounting frame 6 and the primary vibration damping base frame 5, and each of the multiple vibration damping ball mounting frames 7 is provided with a vibration damping ball 8.

[0032] In contrast to the shortcomings of existing technologies, in this invention, multiple shock-absorbing ball mounting frames 7 are inclinedly arranged between the primary shock-absorbing mounting frame 6 and the primary shock-absorbing base frame 5, so that multiple shock-absorbing balls 8 located on the multiple shock-absorbing ball mounting frames 7 can provide buffering when subjected to impacts in the vertical and horizontal directions, so that the pod shock-absorbing structure has the advantages of good shock absorption effect and improved pod stability.

[0033] like Figures 2 to 3 As shown, in some embodiments, the pod mounting platform 1 further includes a secondary damping mechanism 9 disposed on the primary damping mechanism 3. The secondary damping mechanism 9 includes a secondary damping mounting frame 10, a fuselage connecting plate 11, and two secondary damping arms 12. The secondary damping mounting frame 10 is disposed opposite to the fuselage connecting plate 11. One end of each of the two secondary damping arms 12 is connected to the secondary damping mounting frame 10, and the other end is connected to the lower part of the fuselage connecting plate 11 through a secondary damping column 13. A secondary damping buckle 15 is connected between the upper part of the fuselage connecting plate 11 and the secondary damping mounting frame 10. The fuselage connecting plate 11 is used to connect to the main body of the UAV.

[0034] It should be noted that when the primary damping mechanism 3 is subjected to excessive impact, the secondary damping mechanism 9 can absorb the impact energy to achieve a stronger damping effect. Specifically, secondary damping is achieved through the damping action of the secondary damping column 13 and the secondary damping buckle 15.

[0035] like Figures 2 to 3 As shown, in some embodiments, both secondary damping arms 12 are connected to the primary damping base frame 5. The primary damping base frame 5, the secondary damping mounting frame 10, and the two secondary damping arms 12 form a lever structure, with the connection point between the two secondary damping arms 12 and the primary damping base frame 5 serving as the fulcrum 14. Specifically, the lever structure formed by the primary damping base frame 5, the secondary damping mounting frame 10, and the two secondary damping arms 12 can convert the tendency of vertical vibration experienced by the pod 2 into a tendency of rotation along the fulcrum 14. Since the rotational tendency is smoother during movement, it has less impact on the visual effect. Moreover, through the above-mentioned lever structure, the energy absorption and damping effect of the secondary damping mounting frame 10 and the secondary damping buckle 15 on the primary damping mechanism 3 and the pod 2 is multiplied by a lever arm factor, improving the damping effect and thus improving the stability of the pod.

[0036] like Figures 2 to 3 As shown, in some embodiments, the two secondary damping columns 13 are located close to the fulcrum 14. Specifically, by placing the two secondary damping columns 13 close to the fulcrum 14, a damping effect can be achieved on the one hand, and direct impact of the fulcrum 14 on the fuselage connecting plate 11 can be avoided on the other hand, thus providing a buffer protection function.

[0037] like Figures 6 to 7 As shown, in some embodiments, the secondary damping buckle 15 includes a first fastener 16, a second fastener 17, and a damping column 18. The first fastener 16 is connected to the secondary damping mounting bracket 10, with its opening facing the bracket 10. The second fastener 17 is connected to the fuselage connecting plate 11, with its opening facing the plate 11. The openings of the first fastener 16 and the second fastener 17 engage. The damping column 18 is connected between the first fastener 16 and the second fastener 17. The damping column 18 is simultaneously located within the openings of both the first fastener 16 and the second fastener 17. Specifically, when the pod 2 is connected to the primary shock absorption mechanism 3, the secondary shock absorption mounting bracket 10 and the secondary shock absorption buckle 15 connected thereto tend to rotate toward the pod 2, thus squeezing the shock absorption column 18 located between the first fastener 16 and the second fastener 17, and then being fixed by the action of the secondary shock absorption buckle 15 connected to the fuselage connecting plate 11.

[0038] It is worth mentioning that since damping materials / mechanisms typically achieve damping through compression to absorb energy, although damping can also be achieved through spring tension, its energy absorption and damping effect is weak, and spring tension is prone to fatigue and has a limited lifespan. Therefore, by setting the secondary damping buckle 15, the separation tendency of the secondary damping mounting bracket 10 and the fuselage connecting plate 11 is transformed into the approach tendency of the first fastener 16 and the second fastener 17. This transforms the tension of the secondary damping mounting bracket 10 and the fuselage connecting plate 11 into the compression of the damping column 18 between the first fastener 16 and the second fastener 17, thereby improving the stability of the connection, the damping effect, and the lifespan of the damping mechanism.

[0039] like Figures 4 to 5 As shown, in some embodiments, the bottom of the pod mounting platform 1 is connected to the pod 2 via a pod connecting part 19. The pod mounting platform 1 is also provided with an unlocking mechanism 20, which is used to unlock the pod 2. Specifically, the unlocking mechanism 20 triggers the unlocking of the pod 2, allowing the pod 2 to detach from the pod connecting part 19.

[0040] like Figures 4 to 5 As shown, in some embodiments, the unlocking mechanism 20 includes a lever bracket 21, on which a lever 22 is rotatably connected. One end of the lever 22 has a toggle part 23, and the other end has a trigger end 25. An unlocking trigger switch 26 is provided on the pod mounting platform 1. When the toggle part 23 is toggleed, the trigger end 25 triggers the unlocking trigger switch 26 to unlock. Specifically, since the unlocking mechanism 20 in the prior art is often located near the pod 2 or the pod connecting part 19, it is inconvenient to operate. At the same time, in this invention, by toggle the toggle part 23 of the lever 22, the trigger end 25 of the lever 22 rotates to trigger the unlocking trigger switch 26 to achieve unlocking. Therefore, the unlocking method of this invention by toggle the lever 22 can expand the operating range and increase the convenience of operation.

[0041] like Figures 4 to 5 As shown, in some embodiments, a limit feedback protrusion 27 is provided on the lever bracket 21, and the lever 22 is limited by the limit feedback protrusion 27 when the trigger end 25 triggers the unlock trigger switch 26. Specifically, the limit feedback protrusion 27 is used to limit the position of the lever 22 and provide feedback to the operator that the lever 22 is in place; when the operator moves the lever 22 to the limit feedback protrusion 27, the trigger end 25 of the lever 22 presses the unlock trigger switch 26, thereby releasing the lock of the pod 2, and the operator can then remove the pod 2.

[0042] like Figures 1 to 4As shown, in some embodiments, a plurality of the damping balls 8 are arranged around the primary damping mounting frame 6. Specifically, the number of damping balls 8 can be four, with four damping balls 8 arranged around the primary damping mounting frame 6.

[0043] In addition, the present invention also provides a drone, which includes a main body and a pod shock absorption structure, wherein the main body is connected to the fuselage connecting plate 11.

[0044] The specific structure of the drone is as described in the above embodiments. Since the drone adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
