Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an anti-falling unmanned aerial vehicle mounting device and method. Background Art

[0002] The drone-mounted device can carry a variety of equipment, connecting various equipment or payloads to the drone to achieve components with specific mission functions, including high-definition cameras, satellite modules, laser radars, infrared thermal imagers and other products. The unused equipment can be replaced according to different mission requirements.

[0003] Due to the different products carried on the drone and the inconsistent center of gravity of each carried product, direct carrying flight can easily affect flight stability. The drone may sway left and right, pitch instability or yaw, making it difficult to maintain a stable flight posture, reducing flight performance. It will also affect the use of the carried equipment. Inconsistent center of gravity may cause the equipment to be unable to maintain a stable posture, and the drone will vibrate during flight. Long-term flight use can easily cause the connectors to fall off, and safety accidents such as the carried products falling off can easily occur.

[0004] A UAV mounting device and a UAV are disclosed in the patent application with reference publication number CN111874245A. The mounting device effectively realizes one-to-many adaptation of the mounting device and the mounting equipment through the cooperation of the mobile connecting buckle and the fixed connecting pin, and avoids the problem of troublesome operation when disassembling and replacing the mounting equipment.

[0005] The above-mentioned UAV carrying device completes the locking operation of the carrying equipment through the cooperation of the connecting buckle and the connecting pin. Although it can complete the carrying operation, it cannot complete the automatic detection and adjustment operation of the center of gravity position for different carrying equipment. Therefore, there is a deviation between the center of gravity of the carrying equipment and the UAV, which is very likely to interfere with the flight of the UAV and has a high risk. At the same time, it affects the operational stability of the carrying equipment. Moreover, the above-mentioned carrying device cannot complete stable multiple locking for the carrying equipment. Therefore, in the vibration environment of the UAV flight, the carrying equipment is very likely to loosen and fall off, which reduces safety and stability, and is very likely to cause safety accidents, which is not conducive to the stable implementation of the flight mission.

The embedded part is connected to the temporary storage part. The center of gravity of the mounting device 12 is dynamically known through the movable ball head 6. The two-axis adjustment table 9 is specifically a linear module in the X and Y axes. The linear module specifically adopts one of an electric slide and a manual slide. The linear module in the Y axis is arranged at the output end of the linear module in the X axis. It can complete the adjustment of X and Y on the assembly seat 8. The electric slide and the manual slide are both equipped with a self-locking function to ensure stable adjustment.

[0071] The positioning mechanism is hidden in the control shaft 3. The positioning mechanism is divided into an insert and a follower. The insert can be raised and lowered on the control shaft 3 to complete the dynamic positioning of the active ball head 6. The follower is connected with the insert to complete the active control of the temporary storage. At the same time, the cooperation between the follower and the temporary storage completes the additional reinforcement of the assembly seat 8.

[0072] In the embodiment of the present invention, a mounting area 13 is formed on the connecting seat 2, a semi-open area 14 is formed at the bottom of the connecting seat 2, guide rails 15 are formed on both sides of the inner wall of the semi-open area 14, and the lifting seat 4 is slidably mounted in the mounting area 13;

[0073] The connector includes:

[0074] The connecting plate 16 is slidably engaged in the semi-open area 14, and the two ends of the connecting plate 16 are correspondingly slidably engaged in the guide rails 15. The connecting plate 16 is detachably fixed to the bottom of the connecting seat 2 by bolts and other structures, and two handles are symmetrically installed on both sides of the bottom of the connecting plate 16;

[0075] The hidden area is opened on one side of the connecting plate 16. Two No. 1 extrusion chambers 17 are symmetrically installed on both sides of the hidden area. A No. 1 piston member 18 is slidingly sealed in each No. 1 extrusion chamber 17. A No. 1 spring for resetting is installed between each No. 1 extrusion chamber 17 and the No. 1 piston member 18. An intercommunication pipe 19 is installed between the two No. 1 extrusion chambers 17, and the intercommunication pipe 19 is connected with the temporary storage member through a pipeline;

[0076] Two reinforcement grooves 20 are symmetrically opened on one side of the semi-open area 14, and each No. 1 piston member 18 can slide and extend into the reinforcement groove 20;

[0077] It is worth mentioning that when the control shaft 3 is connected to the connecting seat 2: by providing a connecting piece, the connecting plate 16 is pushed into the semi-open area 14, and slidably engaged into the guide track 15, and then the connecting plate 16 and the connecting seat 2 are connected by bolts to complete the primary fixation, and then the control shaft 3 drives the lifting seat 4 to extend to the installation area 13 of the connecting seat 2, and the lifting seat 4 is slidably set in the installation area 13, which can complete the secondary fixation of the control shaft 3 and the connecting seat 2. With the help of the engagement of the lifting seat 4 and the connecting seat 2, the control shaft 3 can be blocked during the falling process, thereby improving safety, and can complete the guidance use for the up and down movement of the control shaft 3.

[0078] Embodiment 2: Based on the vibration reduction unit provided in Embodiment 1, this embodiment provides a further technical solution of the vibration reduction unit.

[0079] like Figure 5 As shown, the vibration reduction unit comprises:

[0080] The retaining ring 21 is sleeved on the outside of the control shaft 3. A damping spring 22 is provided between the retaining ring 21 and the connecting plate 16 of the connecting member. The damping spring 22 is sleeved on the outside of the control shaft 3.

[0081] A plurality of dampers 23 are distributed in a rectangular shape at the bottom of the lifting seat 4 of the connecting member, each damper 23 is in contact with the bottom of the mounting area 13 of the connecting seat 2, and the damper 23 is specifically one of a liquid damper 23, a rubber damper 23 and a friction damper 23;

[0082] It is worth noting that: when the carrying unit is subjected to vibration reduction control: a vibration reduction unit is provided, and multiple dampers 23 are arranged between the lifting seat 4 and the connecting seat 2. When the control shaft 3 vibrates up and down, the vibration can be absorbed by means of multiple dampers 23, and the control shaft 3 and the self-weight of the carrying device 12 produce a downward movement trend, which further ensures the stable contact between the damper 23 and the connecting seat 2, and can achieve a good vibration reduction state. The position design of the vibration reduction spring 22 is optimized. The vibration reduction spring 22 is arranged below the connecting plate 16. The vibration reduction spring 22 also provides a downward movement trend. The vibration can be flexibly absorbed by the damper 23. With this design, the vibration generated by the operation of the drone body 1 can be absorbed in multiple ways through the vibration reduction unit and the control shaft 3, thereby improving safety and ensuring the stability of each connection point, thereby avoiding safety accidents caused by looseness and falling.

[0083] Embodiment 3: Based on the positioning mechanism provided in Embodiment 1, this embodiment provides a further technical solution for the positioning mechanism.

[0088] It is worth noting that when adjusting the center of gravity of the carrying device 12: by providing a positioning mechanism, when the carrying device 12 is connected to the carrying seat 10 through the carrying base plate 11, the plug-in 28 is separated from the inner locking channel 7 of the movable ball head 6 and is not in contact with it, so that the weight of the carrying device 12 directly acts on the movable ball head 6, and the carrying device 12 is disturbed by its center of gravity, which drives the movable ball head 6 to change its posture, which is beneficial for the installer to know the center of gravity position of the carrying device 12, and then operate the two-axis adjustment platform 9 to adjust the position of the carrying device 12 in the X and Y axes, and adjust the center of gravity of the carrying device 12 to be relatively consistent with the center of gravity of the drone body 1, thereby ensuring the stability of the subsequent flight of the drone body 1, and at the same time, it can be adjusted and used for different carrying devices 12, enriching the types of carrying devices 12. After the center of gravity adjustment is completed , it is only necessary to turn the hand wheel, and the worm gear 25 is driven to rotate via the worm 26, and the threaded sleeve 29 is driven to rotate at the same time, so as to push the lifting screw 30 to extend in the threaded sleeve 29, and push the plug-in 28 to move down in the hollow area 27, so that the plug-in 28 is correspondingly inserted into the inner locking channel 7 to complete the locking operation of the active ball head 6 and the carrying device 12, and when the plug-in 28 moves down, it synchronously drives multiple reinforcing arms 32 to follow the sliding, and multiple reinforcing arms 32 contact and trigger with the temporary storage part during the downward movement, and at the same time, multiple reinforcing arms 32 form a multi-point rigid connection with the assembly seat 8 through the temporary storage part, so that the assembly seat 8 and the carrying device 12 can be reinforced at multiple points, thereby ensuring the stability of the carrying device 12, and at the same time improving the torsion resistance of the control shaft 3, and being able to maintain the strength of the carrying device 12 in a complex working environment, thereby extending the service life;

[0089] The positioning mechanism also includes:

[0090] Four sliding areas 31 are distributed around the control shaft 3 in a rectangular shape;

[0091] Four reinforcing arms 32 are slidably engaged in the four sliding areas 31, and each reinforcing arm 32 is connected to the plug-in 28;

[0092] like Fig.11 As shown, in an embodiment of the present invention, the temporary storage component includes:

[0093] The annular cavity 33 is detachably mounted on the top of the assembly seat 8. A certain amount of medium is injected into the annular cavity 33. The medium is specifically oil, which can synchronously control the embedded parts and the connecting parts. An end cover is detachably sealed and installed in the open area at the top of the annular cavity 33. A No. 1 pipe is connected and installed on one side of the bottom of the annular cavity 33, and a No. 2 pipe is connected and installed on the other side of the bottom of the annular cavity 33. The No. 2 pipe is connected to the interconnecting pipe 19 of the connecting part through a flexible pipe.

[0094] A control ring 34 is installed in the annular cavity 33 with a sliding seal. A plurality of guide rods 35 are arranged in a circular array on the control ring 34. Each guide rod 35 is arranged to slide through the end cover.

[0095] The contact ring 36 is arranged on the top of the plurality of guide rods 35. A second spring is sleeved on the outside of each guide rod 35. The contact ring 36 is normally separated from the reinforcing arm 32 of the positioning mechanism. The second spring is located between the contact ring 36 and the end cover to control the reset.

[0096] like Fig.13 and Fig.14 As shown, in an embodiment of the present invention, the embedded component includes:

[0097] The groove 37 is recessed on the mounting seat 10, and two reserved areas are extended on both sides of the groove 37 on the mounting seat 10;

[0098] A protrusion 38 is protruded on the mounting substrate 11 and can extend into the groove 37;

[0099] The moving area is hidden and opened in the bottom of the mounting seat 10 and communicates with the groove 37. A gear 39 is rotatably installed in the middle position of the moving area. A first rack 40 is slidably installed on one side of the moving area, and a second rack 41 is slidably installed on the other side of the moving area.

[0101] Two inner locking grooves 43 are symmetrically arranged on both sides of the protruding member 38, and the two inner locking blocks 42 can extend into the inner locking grooves 43 to complete locking;

[0102] The second extrusion chamber 44 is arranged on one side of the mounting seat 10, and a second piston member 45 is installed in the second extrusion chamber 44 in a sliding and sealing manner.
