Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a shock-absorbing mounting structure and a UAV. Background Technology

[0002] With the gradual maturation of drone technology, especially the rapid decline in the price of small drones, their advantages in the field of aerial photography are becoming increasingly apparent. Using multi-rotor drones for aerial photography offers advantages such as high safety, good flexibility, stable attitude, low cost, and access to dangerous airspace.

[0003] However, during flight, drones often experience high-frequency camera vibrations due to propeller rotation, gimbal shaking, and strong winds, resulting in poor image quality and requiring extensive post-processing to minimize the impact of camera shake. However, the processed data is often still unsatisfactory. Therefore, it is necessary to install a shock-absorbing mechanism between the drone body and the pod.

[0004] Currently, most shock absorption mechanisms used in drones consist of multiple shock-absorbing balls made of rubber or silicone placed between two or more mounting plates. The shock absorption structure made of silicone rubber has poor durability and is not suitable for use in high and low temperature weather environments. In addition, once damaged, the entire shock absorption structure needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0005] The main purpose of this utility model is to propose a shock-absorbing installation structure and a drone, which aims to solve the problems of poor durability and high maintenance costs of existing drone shock-absorbing mechanisms.

[0006] To achieve the above objectives, this utility model proposes a shock-absorbing mounting structure, including a first mounting frame and a second mounting frame. The first mounting frame includes a first connecting mechanism connected to the UAV body, and the second mounting frame includes a second connecting mechanism connected to the pod. The first mounting frame and the second mounting frame are connected by a shock-absorbing mechanism. The shock-absorbing mechanism includes multiple steel wire shock-absorbing components arranged at intervals. Each steel wire shock-absorbing component includes an upper connecting seat, a lower connecting seat, and multiple steel wire ropes. The multiple steel wire ropes are arranged at intervals around the lower connecting seat. One end of each steel wire rope is detachably connected to the upper connecting seat, and the other end is detachably connected to the lower connecting seat. The length of each steel wire rope is greater than the distance between the upper connecting seat and the lower connecting seat.

[0007] According to some embodiments of the present invention, the shock absorption mechanism further includes a plurality of springs, the two ends of which are respectively connected to the first mounting bracket and the second mounting bracket, and each spring is disposed between two adjacent steel wire shock absorption components.

[0008] According to some embodiments of the present invention, the plurality of steel wire damping components are evenly distributed in the circumferential direction of the first mounting frame, and the spacing between each spring and the adjacent steel wire damping component is consistent.

[0009] According to some embodiments of the present invention, the upper connecting seat and the lower connecting seat are both square and arranged opposite to each other, and there are four steel wire ropes, which are evenly distributed in the circumference of the upper connecting seat and the lower connecting seat.

[0010] According to some embodiments of the present invention, threaded holes are provided on all four sides of the upper connecting seat and the lower connecting seat, and bolts are connected to both ends of each wire rope. One end of the wire rope is connected to the upper connecting seat through the bolt and the threaded hole, and the other end is connected to the lower connecting seat through another bolt and another threaded hole.

[0011] According to some embodiments of the present invention, each side of the upper connecting seat and the lower connecting seat has two threaded holes.

[0012] According to some embodiments of the present invention, the first mounting bracket further includes a first connecting plate, a first connecting member, and a first mounting plate that can be connected to the first connecting mechanism. The first connecting plate and the first mounting plate are connected by the first connecting member. The second mounting bracket further includes a second connecting plate, a second connecting member, and a second mounting plate that can be connected to the second connecting mechanism. The second connecting plate is located between the first connecting plate and the first mounting plate. The first connecting plate has an opening in the middle. One end of the second connecting member is connected to the second mounting plate, and the other end passes through the opening and is connected to the second connecting plate. The diameter of the second connecting plate is larger than the diameter of the opening.

[0013] According to some embodiments of the present invention, the upper connecting seat of the steel wire shock absorber assembly is connected to the second connecting plate, and the lower connecting seat is connected to the first connecting plate.

[0014] According to some embodiments of the present invention, the second connecting mechanism has two engaging slots into which the two connectors of the pod can respectively extend and engage.

[0015] In addition, this utility model also provides a drone, including a drone body, a pod, and a shock-absorbing mounting structure as described in any of the above. The crossbeam of the drone body is detachably connected to the first connecting mechanism of the first mounting frame, and the connector of the pod is detachably connected to the second connecting mechanism of the second mounting frame.

[0016] This utility model has at least the following beneficial effects:

[0017] In this invention, the shock absorption mechanism includes multiple steel wire shock absorption components arranged at intervals. Vibration is eliminated by the deformation of the steel wire ropes in the steel wire shock absorption components. Since the steel wire ropes are made of metal, they are more durable than existing silicone rubber shock absorption balls, can be used in high and low temperature weather environments, and have a longer service life. Furthermore, since one end of each steel wire rope is detachably connected to the upper connecting seat and the other end is detachably connected to the lower connecting seat, even if individual steel wire ropes break after multiple deformations, only the broken steel wire ropes need to be replaced to complete the repair of the shock absorption mechanism, resulting in extremely low repair costs and high repair efficiency.

[0029] This utility model provides a shock-absorbing installation structure and a drone. Figures 1 to 5 This invention provides a specific embodiment of a shock-absorbing installation structure and a drone.

[0030] like Figures 1 to 3As shown, this utility model embodiment provides a shock-absorbing mounting structure 100, including a first mounting frame 1 and a second mounting frame 2. The first mounting frame 1 includes a first connecting mechanism 11 connected to the UAV body, and the second mounting frame 2 includes a second connecting mechanism 21 connected to the pod. The first mounting frame 1 and the second mounting frame 2 are connected by a shock-absorbing mechanism 3. The shock-absorbing mechanism 3 includes a plurality of steel wire shock-absorbing components 31 arranged at intervals. Each steel wire shock-absorbing component 31 includes an upper connecting seat 311, a lower connecting seat 312, and a plurality of steel wire ropes 313. The plurality of steel wire ropes 313 are arranged at intervals in the circumferential direction of the lower connecting seat 312. One end of each steel wire rope 313 is detachably connected to the upper connecting seat 311, and the other end is detachably connected to the lower connecting seat 312. The length of each steel wire rope 313 is greater than the distance between the upper connecting seat 311 and the lower connecting seat 312.

[0031] In this invention, the shock absorption mechanism 3 includes multiple steel wire shock absorption components 31 arranged at intervals. Vibration is eliminated by the deformation of the steel wire ropes 313 in the steel wire shock absorption components 31. Since the steel wire ropes 313 are made of metal, they are more durable than existing silicone rubber shock absorption balls, can be used in high and low temperature weather environments, and have a longer service life. Furthermore, since one end of each steel wire rope 313 is detachably connected to the upper connecting seat 311 and the other end is detachably connected to the lower connecting seat 312, even if individual steel wire ropes 313 break after multiple deformations, only the broken steel wire ropes 313 need to be replaced to complete the repair of the shock absorption mechanism 3. The repair cost is extremely low and the repair efficiency is high.

[0032] Because drones experience various types of vibration during operation, in order to improve the stability of the drone-borne pod, in some embodiments, such as... Figure 3 and Figure 4 As shown, the vibration damping mechanism 3 also includes multiple springs 32, with both ends of each spring 32 connected to the first mounting bracket 1 and the second mounting bracket 2, respectively. Each spring 32 is positioned between two adjacent wire vibration damping components 31. This arrangement allows the wire vibration damping components 31 to eliminate high-frequency, low-amplitude vibrations, while the springs 32 eliminate low-frequency, high-amplitude vibrations. Combining the wire vibration damping components 31 and the springs 32 optimizes vibration damping performance and further improves the imaging quality of the camera installed in the pod.

[0033] Preferably, in some embodiments, such as Figure 3 and Figure 4As shown, the plurality of wire vibration damping components 31 are evenly distributed circumferentially on the first mounting frame 1, and the spacing between each spring 32 and the adjacent wire vibration damping component 31 is consistent. This arrangement, through the uniform distribution of the wire vibration damping components 31 and the springs 32, ensures that the vibration damping effect is consistent across all parts of the vibration damping mounting structure 100, thereby ensuring consistent imaging effects from all angles captured by the camera.

[0034] Furthermore, in some embodiments, such as Figure 5 As shown, both the upper connecting seat 311 and the lower connecting seat 312 are square and arranged opposite each other. Four steel wire ropes 313 are provided, and the four steel wire ropes 313 are evenly distributed circumferentially on the upper connecting seat 311 and the lower connecting seat 312. This arrangement ensures that when subjected to vertical vibration, the stress and deformation of each steel wire rope 313 are consistent, preventing some steel wire ropes 313 from experiencing excessive stress and breaking.

[0035] The specific connection method between the wire rope 313 and the upper connecting seat 311 and the lower connecting seat 312 is not limited, as long as both ends of the wire rope 313 are detachably connected to the upper connecting seat 311 and the lower connecting seat 312 respectively. For example, in some embodiments, such as Figure 5 As shown, threaded holes 3111 are provided on all four sides of the upper connecting seat 311 and the lower connecting seat 312. Bolts 314 are connected to both ends of each wire rope 313. One end of each wire rope 313 is connected to the upper connecting seat 311 via the bolt 314 and the threaded hole 3111, and the other end is connected to the lower connecting seat 312 via another bolt 314 and another threaded hole 3111. This configuration allows the bolts 314 to be threaded into all the threaded holes 3111. One end of each wire rope 313 is connected to one side of the lower connecting seat 312, and the other end can be connected to the corresponding side of the upper connecting seat 311, or to an adjacent side of the corresponding side of the upper connecting seat 311. This tilted and twisted arrangement of the wire rope 313 allows the wire vibration damping assembly 31 to simultaneously filter vertical motor vibration and lateral airflow disturbances, improving the camera's imaging stability.

[0036] Specifically, the end of the wire rope 313 and the bolt 314 are connected by a bearing. The end of the wire rope 313 is connected to the inner ring of the bearing, and the bolt 314 is connected to the outer ring of the bearing. This arrangement prevents the wire rope 313 from breaking due to excessive twisting when the bolt 314 is rotated to connect with the threaded hole 3111.

[0037] Furthermore, in some embodiments, such as Figure 5As shown, each side of the upper connecting seat 311 and the lower connecting seat 312 has two threaded holes 3111. By connecting the bolt 314 to different threaded holes 3111 on adjacent sides, the torsion angle of the wire rope 313 is changed, the damping ratio of the wire rope 313 is adjusted, and the energy dissipation efficiency in the resonance zone is optimized.

[0038] The specific structures of the first mounting bracket 1 and the second mounting bracket 2 are not limited. For example, in some embodiments, such as... Figures 1 to 4 As shown, the first mounting bracket 1 further includes a first connecting plate 12, a first connecting member 13, and a first mounting plate 14 that can be connected to the first connecting mechanism 11. The first connecting plate 12 and the first mounting plate 14 are connected by the first connecting member 13. The second mounting bracket 2 further includes a second connecting plate 22, a second connecting member 23, and a second mounting plate 24 that can be connected to the second connecting mechanism 21. The second connecting plate 22 is located between the first connecting plate 12 and the first mounting plate 14. The first connecting plate 12 has an opening in the middle. One end of the second connecting member 23 is connected to the second mounting plate 24, and the other end passes through the opening and is connected to the second connecting plate 22. The diameter of the second connecting plate 22 is larger than the diameter of the opening. With this configuration, the second connecting plate 22 is placed between the first connecting plate 12 and the first mounting plate 14, and the diameter of the second connecting plate 22 is larger than the opening diameter of the first connecting plate 12. Even if all the steel wire ropes 313 of the steel wire shock absorption assembly 31 break during the flight of the UAV, the first mounting frame 1 and the second mounting frame 2 will not become disconnected, thus improving the reliability of the shock absorption mounting structure 100.

[0039] Specifically, in some embodiments, such as Figure 3 and Figure 4 As shown, the upper connecting seat 311 of the wire rope damping assembly 31 is connected to the second connecting plate 22, and the lower connecting seat 312 is connected to the first connecting plate 12. This configuration ensures that during drone flight, the wire rope damping assembly 31 is in a compressed state, and the wire rope 313 is tightly twisted under pressure, increasing the lateral stiffness of the wire rope 313 and making it more resistant to lateral airflow gusts. Furthermore, compared to the stretched state, no additional anti-sway structure is required.

[0040] The specific structure of the second connecting mechanism 21 is not limited, as long as the second connecting mechanism 21 is connected to the pod. For example, in some embodiments, such as... Figure 1 and Figure 2As shown, the second connecting mechanism 21 has two engaging slots 211 into which the two connectors of the pod can respectively extend and engage. The connection is completed by inserting the two connectors of the pod into the corresponding engaging slots 211. Specifically, the second connecting mechanism 21 includes a locking part 212, which can lock the connectors and engaging slots 211 in place by turning the locking part 212.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the first connecting mechanism 11 includes four fixing members 111, which are arranged at the four vertices of a rectangle. The fixing members 111 have through holes through which the crossbeam of the UAV body passes.

[0042] In addition, this utility model also provides a drone, including a drone body, a pod, and the shock-absorbing mounting structure 100. The crossbeam of the drone body is detachably connected to the first connecting mechanism 11 of the first mounting frame 1, and the connector of the pod is detachably connected to the second connecting mechanism 21 of the second mounting frame 2.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
