Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV support shock absorption device. Background Technology

[0002] An unmanned aerial vehicle (UAV) is an aircraft capable of autonomous flight without human control. It is typically controlled via remote control or a pre-programmed flight path. UAVs usually carry various types of sensors and payloads, such as high-definition cameras, thermal imagers, and lidar, to collect data including images, videos, and geographic information. This data can be used in fields such as geological exploration, environmental monitoring, disaster management, and agricultural optimization.

[0003] The drone consists of a main body and a fixed support. The main body and the fixed support are connected. After the drone completes data collection, the relevant personnel operate the drone to land in a designated area so that the fixed support is placed steadily on the ground to complete the recovery of the drone. However, during the recovery process, it was found that the drone would be subjected to a large impact during descent. The impact was transmitted to the main body through the fixed support, causing significant damage to the drone.

[0004] To reduce damage during drone recovery, elastic elements are added to the fixed support for cushioning and shock absorption. However, the addition of elastic elements and a series of auxiliary components significantly increases the space occupied by the drone, making it difficult to store. Summary of the Invention

[0005] The purpose of this application is to provide a shock-absorbing device for a drone support that is easy to store.

[0006] The drone support shock absorption device provided in this application adopts the following technical solution:

[0007] A shock absorption device for a drone support includes a mounting plate, a rotating assembly, and supporting legs. The mounting plate can be connected to the drone body. The mounting plate has a storage slot. The rotating assembly is rotatably connected to the storage slot. The supporting legs are connected to the rotating assembly.

[0008] The rotating assembly includes a main storage plate, a secondary storage plate, and an elastic element. The main storage plate is rotatably connected to the storage slot. The two ends of the elastic element act on the main storage plate and the secondary storage plate, respectively. A sliding groove is provided on the main storage plate. The main storage plate is rotatably connected to the secondary storage plate through the sliding groove. The secondary storage plate can slide along the sliding groove.

[0009] By adopting the above technical solution, when the drone is falling, the elastic element can adaptively contract, allowing the storage sub-plate to slide relative to the storage main plate, thereby reducing the impact force generated by the drone during the fall. After the drone is recovered, the storage sub-plate is pushed, causing the rotating shaft of the storage sub-plate to enter the through hole and rotate relative to the storage main plate. Under the action of the rotating component, the support legs are folded. The rotating component not only plays a role in shock absorption and cushioning during the fall of the drone, but also folds the support legs after the drone is recovered, significantly reducing the space occupied by the drone.

[0010] Optionally, the main storage plate is provided with a fixing member and a fixing groove that matches the fixing member. The fixing groove is connected to the sliding groove. The fixing member can abut against the inner wall of the fixing groove and the sliding groove respectively and pass through the storage sub-plate.

[0011] When the storage sub-plate slides along the storage main plate, if the impact on the storage sub-plate is large, its movement trajectory may deviate. By adopting the above technical solution, the rotating component is rotated to change it from the folded working state to the working state. At this time, the fixing component is placed in the fixing groove and the sliding groove. Since the fixing component passes through the storage main plate and the storage sub-plate in sequence, the storage sub-plate is limited. When the storage sub-plate is impacted, the storage sub-plate moves stably along the length direction of the sliding groove, and the temperature-resistant buffering and shock absorption of the storage component is greatly improved.

[0012] Optionally, limit blocks are provided on both sides of the storage motherboard, and both limit blocks are connected to the mounting bracket plate. Limiting components are provided on both sides of the storage motherboard, and the limiting components are connected to the storage motherboard. Limiting slots matching the limiting components are provided on the limit blocks.

[0013] By adopting the above technical solution, when the storage motherboard is rotated, the limiting components on both sides of the storage motherboard are engaged in the limiting grooves opened in the limiting block. The combination of the limiting components and the limiting block limits the storage motherboard, thereby reducing the possibility of the storage motherboard shaking during rotation and improving the stability of the storage motherboard.

[0014] Optionally, the mainboard for storage has a receiving groove, and the limiting member is placed in the receiving groove. The limiting member includes a limiting ratchet and a retracting rod. The limiting ratchet is connected to the retracting rod, and the elastic element is sleeved on the retracting rod. The two ends of the elastic element act on the limiting ratchet and the inner wall of the receiving groove, respectively. The inner wall of the receiving groove also has a through hole that matches the retracting rod.

[0015] By adopting the above technical solution, the limiting ratchet abuts against the inner wall of the limiting groove. During the rotation of the main board, the elastic element adaptively contracts, locking the limiting ratchet in different limiting grooves to adjust the rotation angle of the main board. Personnel can adjust the main board according to the terrain when the drone lands to change the angle of the support leg relative to the mounting plate, which helps to improve the stability of the support shock absorption device.

[0016] Optionally, the storage main board is further provided with an adjustment component, which is placed in an adjustment hole provided on the storage main board. The adjustment hole is connected to the through hole, and the adjustment component can cause the elastic element to contract.

[0017] Since the position of the rotating component is locked by the combination of the limiting member and the limiting groove after it is rotated out, by adopting the above technical solution, when the drone bracket is retrieved, the adjustment component is activated to make the limiting member retract into the receiving groove, thereby unlocking the rotating component and making the rotating component re-abut against the bottom wall of the storage groove, which is beneficial for the storage of the drone bracket shock absorption device.

[0018] Optionally, the adjustment assembly includes an adjustment knob, an adjustment rod, and an adjustment wire. One end of the adjustment rod is connected to the adjustment knob, and the other end of the adjustment rod is placed in the adjustment hole. The adjustment wire is wound around the adjustment rod and connected to the retraction rod.

[0019] By adopting the above technical solution, when it is necessary to rotate the storage motherboard, which has been rotated to a certain angle, in the opposite direction until it abuts against the inner wall of the storage slot, the adjustment knob is turned so that the adjustment screw pulls the retraction rod. Under the pull of the adjustment screw, the elastic element contracts, causing the limiting ratchet to retract back into the receiving slot, thereby engaging the locking of the limiting ratchet. This is beneficial for the storage of the storage motherboard and the adjustment of its angle.

[0020] Optionally, there are several rotating components and several supporting legs, with each rotating component and supporting leg corresponding to the others, and each rotating component being rotatably connected to the mounting plate.

[0021] By adopting the above technical solution, multiple support legs work together to support the mounting plate, which helps to improve the stability of the support vibration damping device.

[0022] Optionally, the storage sub-plate has a threaded groove at one end near the support leg, and the support leg and the storage sub-plate are slidably connected through the threaded groove.

[0023] During the landing of a drone, the support legs directly bear the impact of descent, making them prone to damage. By adopting the above-mentioned technical solution, the support legs and the storage sub-plate are connected by threads. Personnel can screw the support legs into the storage sub-plate and adjust the support legs by controlling the length of screwing them into the storage sub-plate to adapt to different terrain environments. When the support legs are damaged, personnel can also unscrew them from the storage sub-plate and replace them, which helps to reduce the maintenance cost of the support shock absorption device.

[0024] Optionally, the support leg is further provided with a connecting rod and a buffer pad, the two ends of the connecting rod are respectively connected to the support leg and the buffer pad, and one end of the support leg is rotatably connected to the buffer pad.

[0025] During the descent of a drone, the support legs are directly subjected to the impact of the descent, making them prone to damage. By adopting the above technical solution, the buffer pad is preferably in contact with the ground when the drone is descending, and the buffer pad, connecting rod and support legs form a triangle to support the drone body, which helps to improve the stability of the drone when it is parked.

[0026] Optionally, the support leg has a mounting hole, the mounting hole contains the elastic element, one end of the elastic element abuts against the inner wall of the mounting hole, and one end of the connecting rod passes through the mounting hole and is connected to the other end of the elastic element.

[0027] By adopting the above technical solution, during the process of the buffer pad contacting the ground, the buffer pad preferably contacts the ground. When it is impacted by the ground, the buffer pad also rotates adaptively to reduce the impact in time. At this time, the buffer pad and the connecting rod connected to the buffer pad rotate relative to the support leg, causing the elastic element in the mounting hole to contract, reducing the impact and minimizing the damage to the support leg, which is beneficial to protecting the support leg.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. This application includes a rotating component. When the drone is falling, the elastic element can adaptively contract, allowing the storage sub-plate to slide relative to the storage main plate, thereby reducing the impact force generated by the drone during the fall. After the drone is recovered, the storage sub-plate is pushed, causing the rotating shaft of the storage sub-plate to enter the through hole and rotate relative to the storage main plate. Under the action of the rotating component, the support legs are folded. The rotating component not only plays a shock absorption and cushioning role during the fall of the drone, but also folds the support legs after the drone is recovered, significantly reducing the space occupied by the drone.

[0030] 2. In this application, limit blocks are provided on both sides of the storage motherboard. When the storage motherboard is rotated, the limit pieces on both sides of the storage motherboard are engaged in the limit grooves opened in the limit blocks. The combination of the limit pieces and the limit blocks limits the storage motherboard, thereby reducing the possibility of the storage motherboard shaking during rotation and improving the stability of the storage motherboard.

[0031] 3. The support legs and the storage sub-plate in this application are connected by threads. Personnel can screw the support legs into the storage sub-plate and adjust the support legs by controlling the length of the screwing into the storage sub-plate to suit different terrains. When the support legs are damaged, personnel can also screw the support legs out of the storage sub-plate and replace them, which helps to reduce the maintenance cost of the support shock absorption device.

[0039] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 This application will be described in further detail below.

[0040] A shock absorption device for a drone support, as shown in the reference Figure 1 The system includes a mounting plate, a rotating assembly, and supporting legs. The mounting plate 1 can be connected to the main body of the machine. The mounting plate 1 has a storage slot 11. The rotating assembly 2 is rotatably connected to the inner wall of the storage slot 11. The supporting legs 3 are connected to the rotating assembly 2. There are several rotating assemblies 2 and several supporting legs 3. The several rotating assemblies 2 and several supporting legs 3 are arranged in a one-to-one correspondence. The several rotating assemblies 2 are all rotatably connected to the mounting plate 1.

[0041] Reference Figure 2 The rotating assembly 2 includes a storage main board 21, which is rotatably connected to the storage slot 11. When the drone support shock absorption device is retracted, the storage main board 21 is rotated so that its outer wall is completely flush with the inner wall of the storage slot 11, facilitating folding and storage. Figure 5 Limiting blocks 4 are provided on both sides of the motherboard 21, and both limiting blocks 4 are connected to the mounting plate 1. Limiting components 5 are provided on both sides of the motherboard 21, and the limiting components 5 are connected to the motherboard 21.

[0042] Reference Figure 2 and Figure 3 The motherboard 21 has receiving grooves 212 on both sides of its end, and the limiting member 5 is correspondingly set in the receiving groove 212. Figure 4 The limiting component 5 includes a limiting ratchet 51 and a retracting rod 52. The limiting ratchet 51 is fixedly connected to the retracting rod 52. An elastic element 23 is sleeved on the retracting rod 52. The two ends of the elastic element 23 act on the limiting ratchet 51 and the inner wall of the receiving groove 212, respectively. In this embodiment, the elastic element 23 is preferably a spring. For easy distinction, the elastic element 23 sleeved on the retracting rod 52 is named the first spring 231. One end of the first spring 231 abuts against the limiting ratchet 51, and the other end of the first spring 231 abuts against the inner wall of the receiving groove 212. A through hole 214 matching the retracting rod 52 is also provided on the inner wall of the receiving groove 212.

[0043] Reference Figure 5The limiting block 4 has a limiting groove 41 that matches the limiting component 5. The number of limiting grooves 41 is several and they are evenly distributed according to the rotation direction of the main board 21. When the main board 21 is rotated, the top surface of the limiting ratchet 51 abuts against the side wall of the limiting block 4. At this time, the first spring 231 contracts, and the contraction rod 52 contracts inward along the length direction of the through hole 214. When the limiting ratchet 51 falls into the limiting groove 41, the first spring 231 extends outward, so that the main board 21 is limited. The angle of the main board 21 is adjusted according to the working environment of the drone support shock absorption device, so that the limiting ratchet 51 on the main board 21 falls into the limiting groove 41 corresponding to different angles.

[0044] Reference Figure 2 and Figure 4 An adjustment component 6 is provided on the storage motherboard 21. The adjustment component 6 is placed in the adjustment hole 215 of the storage motherboard 21. The adjustment hole 215 is connected to the through hole 214. The adjustment component 6 can cause the elastic element 23 to contract. The adjustment component 6 includes an adjustment knob 61, an adjustment rod 62 and an adjustment wire 63. One end of the adjustment rod 62 is connected to the adjustment knob 61, and the other end of the adjustment rod 62 is placed in the adjustment hole 215. The adjustment wire 63 is wound around the adjustment rod 62 and connected to the retraction rod 52. When it is necessary to reposition the storage motherboard 21, the adjustment knob 61 is rotated so that the adjustment wire 63 pulls the adjustment rod 62 and drives the limiting ratchet 51 back into the receiving groove 212 to complete the unlocking. Then the storage motherboard 21 is rotated.

[0045] Reference Figure 2 and Figure 3 The rotating assembly 2 also includes a storage sub-plate 22 and an elastic element 23. The storage sub-plate 22 is rotatably connected to the storage main plate 21. The two ends of the elastic element 23 act on the storage main plate 21 and the storage sub-plate 22 respectively. For easy distinction, the elastic element 23 between the storage main plate 21 and the storage sub-plate 22 is named the second spring 232. A hanging ring 26 is fixedly connected to the storage main plate 21. One end of the second spring 232 is rotatably connected to the hanging ring 26, and the other end of the second spring 232 is connected to the storage sub-plate 21. 2. Fixed connection: The main storage plate 21 is provided with a sliding groove 211. The main storage plate 21 is rotatably connected to the secondary storage plate 22 through the sliding groove 211. The main storage plate 21 is provided with a first assembly groove 216. The shape of the secondary storage plate 22 matches that of the first assembly groove 216. The side wall of the first assembly groove 216 abuts against the outer wall of the secondary storage plate 22. The secondary storage plate 22 is rotated along the main storage plate 21 until it is completely placed in the first assembly groove 216, so as to facilitate the folding of the main storage plate 21.

[0046] Reference Figure 1In this application, the top of the mounting plate 1 can be threaded and detachably connected to the body (not shown in the figure). In other embodiments, the mounting plate 1 can also be connected to a clamping assembly to fix it to the body. The clamping assembly includes a clamping plate and a threaded push rod. The threaded push rod abuts against the clamping plate and can push the clamping plate to move. When it is necessary to fix the drone bracket shock absorption device to the body, first rotate the threaded push rod in the opposite direction to make the clamping plates move away from each other to make room for the installation of the body. After placing the body on the mounting plate 1, rotate the threaded push rod to make the clamping plates move closer to each other until they abut against the body to complete the installation (existing technology, which will not be described in detail here).

[0047] To improve the folding effect, the depth of the first mounting groove 216 in this application is consistent with the height direction of the storage sub-plate 22. The storage sub-plate 22 has a second mounting groove 221 to accommodate the hanging ring 26 and the second spring 232. As a preferred embodiment of this application, an assembly block can also be fixedly connected to the storage sub-plate 22. A third mounting groove 217 matching the shape of the assembly block is opened on the inner wall of the first mounting groove 216. When the storage sub-plate 22 is completely placed in the first mounting groove 216, the fixing block 25 cooperates with the third mounting groove 217 to improve the effect of the storage sub-plate 22 being folded into the first mounting groove 216.

[0048] Reference Figure 2 and Figure 3 The sliding groove 211 is opened along the length of the main storage plate 21. The two sides of the storage sub-plate 22 are fixedly connected to the connecting shaft 24. The connecting shaft 24 is placed in the sliding groove 211. The storage sub-plate 22 slides along the sliding groove 211 through the connecting shaft 24. Rotating the storage sub-plate 22 makes the storage component change from a folded state to an unfolded state. At this time, the second spring 232 is set along the length of the sliding groove 211 and can extend and retract along the length of the sliding groove 211. When the storage sub-plate 22 is impacted, the second spring 232 retracts and the connecting shaft 24 moves closer to the main storage plate 21 along the length of the sliding groove 211 to achieve shock absorption and buffering.

[0049] Reference Figure 2 and Figure 3The mainboard 21 is provided with a fixing member 27 and a fixing groove 213 that matches the fixing member 27. Preferably, the fixing member 27 is L-shaped. The fixing groove 213 is connected to the sliding groove 211. The fixing member 27 can abut against the inner wall of the fixing groove 213 and the sliding groove 211 respectively and pass through the storage sub-plate 22. Correspondingly, the storage sub-plate 22 is provided with a through groove 222 that matches the fixing member 27. When the storage sub-plate 22 slides due to the transmitted impact, the fixing member 27 limits the storage sub-plate 22, so that the storage sub-plate 22 slides stably along the length direction of the sliding groove 211, so as to ensure the stability of the rotating component 2 in achieving buffering and shock absorption. When it is necessary to rotate the storage sub-plate 22 to store the drone bracket shock absorption device, the fixing member 27 can be pulled out from the fixing groove 213.

[0050] Reference Figure 6 The storage sub-plate 22 has a threaded groove 31 at one end near the support leg 3. The support leg 3 and the storage sub-plate 22 are slidably connected through the threaded groove 31 to facilitate disassembly and assembly. In other embodiments, the depth of the threaded groove 31 can be set to be the same as the length of the support leg 3. When the unmanned support shock absorption device is no longer working, the support leg 3 can be screwed into the threaded groove 31 through the thread to reduce the space occupied.

[0051] Reference Figure 6 The support leg 3 is also provided with a connecting rod 7 and a buffer pad 8. The two ends of the connecting rod 7 are connected to the support leg 3 and the buffer pad 8 respectively. One end of the support leg 3 is rotatably connected to the buffer pad 8. The support leg 3 is provided with a mounting hole 32. An elastic element 23 is provided in the mounting hole 32. For easy distinction, the elastic element 23 in the mounting hole 32 is named the third spring 233. One end of the third spring 233 abuts against the inner wall of the mounting hole 32. The support leg 3 is also provided with an insertion hole 33. The insertion hole 33 is connected to the mounting hole 32. One end of the connecting rod 7 passes through the insertion hole 33 and is connected to the other end of the third spring 233.

[0052] The implementation principle of this application embodiment is as follows: When the main body needs to work, rotate the storage main plate 21 to a certain angle until the limiting ratchet 51 falls into the limiting groove 41 of the corresponding angle. At this time, the first spring 231 extends outward, and the storage main plate 21 is limited by the limiting member 5. Then, the storage sub-plate 22 is rotated relative to the storage main plate 21 until the second spring 232 can extend and retract along the length direction of the storage main plate 21. At this time, the fixing member 27 is inserted into the fixing groove 213 and the sliding groove 211. The fixing member 27 passes through the through groove 222 of the storage sub-plate 22 to limit the storage sub-plate 22, so that the storage sub-plate 22 can slide stably along the length direction of the sliding groove 211. Then, the support leg 3 is screwed into the threaded groove 31 opened in the storage sub-plate 22, and the depth of the support leg 3 inserted into the storage sub-plate 22 is adjusted accordingly.

[0053] During the descent of the drone body, the shock absorption device between the drones first contacts the ground, the buffer pad 8 on the support leg 3 contacts and adapts to the rotation, the buffer pad drives the connecting rod 7 connected to it to apply pressure to the third spring 233, the third spring 233 adapts to the contraction, at the same time, the second spring 232 also adapts to the contraction, the storage plate 22 slides along the length direction of the sliding groove 211 to achieve overall buffering and shock absorption.

[0054] After the main body is retracted, the support leg 3 is unscrewed from the storage sub-plate 22, and then the fixing piece 27 is pulled out from the fixing groove 213 and the sliding groove 211, so that the storage sub-plate 22 rotates relative to the storage main plate 21 until the outer surface of the storage sub-plate 22 is completely in contact with the inner wall of the first assembly groove 216. At this time, the fixing block 25 fixed on the storage sub-plate 22 is embedded in the third assembly groove 217, so that the storage sub-plate 22 is stably placed in the storage main plate 21. Rotate the adjustment knob 61 so that the adjustment screw 63 pulls the adjustment rod 62 to drive the limit ratchet 51 back to the receiving groove 212 to complete the unlocking. Rotate the storage main plate 21 so that the outer surface of the storage main plate 21 is completely in contact with the inner wall of the storage groove 11 for easy storage and folding.

Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
