Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle cabin cover installation, and in particular to an airbag for unmanned aerial vehicle and an airbag cabin cover installation device. Background Art

[0002] For drones that are recovered by parachuting, the airbags are compressed and installed in the airbag cabin. When the drone is recovered and landed, the airbag cabin cover is opened and the airbag is inflated for landing cushioning. Due to the small size of the airbag cabin, the airbag needs to be compressed before being loaded into the cabin. When the airbag is installed, the cabin cover acts as a pressure plate to compress the airbag. While the airbag is compressed, the cabin cover snaps into place and the screws are tightened to complete the assembly. When installing the cabin cover, the cabin cover compression force should be no less than 80kgf, and the cabin cover is a special-shaped thin-walled part, which makes it difficult to apply force to the cabin cover during assembly. At the same time, drones are often equipped with multiple airbag cabin covers of different shapes.

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0039] Example

[0040] like Figures 1 to 11As shown, the present invention includes a lifting unit 1, on which a support frame 6 is provided, and the lifting unit 1 is used to drive the support frame 6 to move in a vertical direction, and a hatch cover support block 5 with multiple working surfaces is provided on the support frame 6, and the hatch cover support block 5 can rotate on the support frame 6, and a plurality of first magnets 8 are provided on the hatch cover support block 5, and the first magnets 8 are distributed on the side wall of the hatch cover support block 5 in a circular array around the rotation axis of the hatch cover support block 5 and the support frame 6, and a magnetic coupling member 7 is also provided on the support frame 6, and the magnetic coupling member 7 is aligned with one of the first magnets 8.

[0041] In view of the prior art, when installing the airbag hatch of the drone, the hatch cover pressing force should be no less than 80kgf, and because the hatch cover is a special-shaped thin-walled part, it is not convenient to apply force to the hatch cover during assembly. At the same time, the drone is often provided with multiple airbag hatch covers of different shapes, resulting in an urgent need for an installation device that improves the assembly efficiency of the drone hatch cover. To this end, the present technical solution designs a lifting unit 1, which can drive the support frame 6 to move in the vertical direction. At the same time, a hatch cover support block 5 is arranged on the support frame 6, wherein the four surfaces of the hatch cover support block 5 are respectively provided with profiles that match the corresponding hatch cover shape, ensuring that the hatch cover support block 5 can evenly apply force to the airbag hatch cover. In this way, when installing airbag hatch covers of different shapes, it is only necessary to place the airbag hatch cover to be installed on the working surface of the corresponding hatch cover support block 5, and then use the lifting unit 1 to drive the hatch cover support block 5 to move upward, so that the airbag hatch cover located on the hatch cover support block 5 is pressed into the airbag cabin of the drone, thereby realizing the rapid installation of the drone airbag cabin.

[0042] At the same time, in order to ensure that multiple hatch covers can be installed, the hatch cover support block 5 is capable of rotating on the support frame 6 along different working surfaces of the hatch cover support block 5, so as to realize rapid switching of different working surfaces of the hatch cover support block 5; and, in order to ensure that the airbag hatch cover to be installed on the hatch cover support block 5 is in a vertically upward state, so that the lifting unit 1 can smoothly press the hatch cover support block 5 on the hatch cover support block 5 into the airbag cabin of the drone, a magnetic coupling member 7 is also provided on the support frame 6, and four first magnets 8 are provided on the side of the hatch cover support block 5. In this way, when one of the working surfaces of the hatch cover support block 5 is rotated to a vertically upward state, one of the first magnets 8 is aligned with the magnetic coupling member 7, and the first magnet 8 is used to couple with the magnetic coupling member 7. The suction force generated between the coupling parts 7 can flexibly lock the working surface of the hatch cover support block 5. Similarly, when an airbag compartment of other shapes needs to be installed, when the hatch cover support block 5 is rotated to a vertically upward state on its working surface of the corresponding shape, the set magnetic coupling part 7 is also just aligned with one of the first magnets 8, and the magnetic force is used to flexibly lock the working surface of the hatch cover support block 5. Therefore, in the present technical solution, the magnetic coupling between the magnetic coupling part 7 and the first magnet 8 can avoid rigid connection, thereby ensuring the flexibility of the hatch cover support block 5 when working, so that the airbag compartment cover has a certain amount of activity during installation, ensuring that the airbag compartment cover can be accurately installed in the airbag compartment of the drone, and preventing the rigid connection from causing damage to the drone.

[0043] The lifting unit 1 includes a bottom plate 14 and a top plate 17, the support frame 6 is located on the top plate 17, and two groups of scissor fork assemblies are provided between the bottom plate 14 and the top plate 17; the scissor fork assembly includes a first support plate 15 and a second support plate 16, one end of the first support plate 15 is hinged to the bottom plate 14, and the other end is slidably connected to the top plate 17, one end of the second support plate 16 is slidably connected to the bottom plate 14, and the other end is hinged to the top plate 17, and the first support plate 15 is cross-connected with the second support plate 16; a cross plate is also provided between the two groups of scissor fork assemblies, and the two ends of the cross plate are respectively connected to the two second support plates 16, and a driving mechanism is also provided on the cross plate, the driving mechanism is hinged to the cross plate, and the output end of the driving mechanism is hinged to the first support plate 15.

[0044] In order to realize the movement of the hatch cover support block 5 in the vertical direction in the present embodiment, the lifting unit 1 is provided to include a bottom plate 14 and a top plate 17, and two sets of scissor assemblies are provided between the bottom plate 14 and the top plate 17. When working, the provided driving mechanism is used to apply a thrust to the first support plate 15, forcing the first support plate 15 to rotate upward around the hinge of the bottom plate 14, so that the other end of the first support plate 15 slides on the top plate 17, thereby realizing the adjustment of the height of the top plate 17. When the top plate 17 moves, the provided second support plate 16 also synchronously realizes the support of the top plate 17, and finally the airbag hatch cover on the hatch cover support block 5 is pushed into the airbag cabin of the drone, thereby realizing the installation of the airbag hatch cover.

[0045] A first truss is further disposed on the second support plate 16 , a pressure sensor 4 is disposed on the first truss, and the support frame 6 is connected to the pressure sensor 4 .

[0046] The pressure sensor 4 provided in this embodiment is used to collect the tightening value of the hatch cover carried by the hatch cover supporting block 5 after it contacts the UAV body. An electrical control unit 2 is also provided on the top plate 17. The electrical control unit 2 is respectively connected to the pressure sensor 4 and the driving mechanism. The electrical control unit 2 is used to collect the value of the pressure sensor 4 and control the working state of the driving mechanism, so as to adjust the rising amount of the hatch cover supporting block 5, thereby realizing precise control of the hatch cover fastening force.

[0047] The support frame 6 includes a second truss 9 and two vertical plates 10, the two vertical plates 10 are respectively fixed at the two ends of the second truss 9, and the vertical plates 10 are each provided with a first bearing 11, and the first bearing 11 is provided with a first rotating shaft, and the first rotating shaft is connected to the hatch cover support block 5.

[0048] In this embodiment, in order to ensure that the hatch cover support block 5 can rotate smoothly on the support frame 6 and realize rapid switching of different working surfaces, a first bearing 11 for rotating the hatch cover support block 5 is provided on the vertical plate 10. The first bearing 11 is used to ensure that the hatch cover support block 5 can rotate in a vertical plane, thereby realizing switching of the four working surfaces of the hatch cover support block 5.

[0049] A second bearing is further disposed at the bottom of the second truss 9 . A second rotating shaft is disposed on the second bearing. The second rotating shaft is connected to the pressure sensor 4 .

[0050] In this embodiment, in order to realize the rotation of the hatch cover support block 5 on the horizontal plane and meet different installation requirements, a second bearing is further provided on the second truss 9. The second bearing is used to ensure that the support frame 6 can rotate on the horizontal plane to change the position of the hatch cover support block 5.

[0051] The magnetic coupling member 7 includes a fixing seat, an adjusting nut 12 and a second magnet 13. The fixing seat is fixed to one side of the vertical plate 10. The adjusting nut 12 is connected to the fixing seat by threads. A mounting hole is provided in the adjusting nut 12. The second magnet 13 is located in the mounting hole.

[0052] In this embodiment, in order to ensure that the magnetic coupling member 7 can cooperate with the first magnet 8 to flexibly lock the hatch cover support block 5, the magnetic coupling member 7 includes a fixing seat, an adjusting nut 12 and a second magnet 13, wherein the adjusting nut 12 is connected to the fixing seat through a thread, so that by rotating the adjusting nut 12, the distance between the adjusting nut 12 and the hatch cover support block 5 can be adjusted, thereby realizing the adjustment of the magnetic force between the first magnet 8 and the second magnet 13 to meet different usage requirements.

[0053] The driving mechanism includes a cylinder body 19, a cylinder bottom 18, a cylinder cover 22, a piston 20 and a piston rod 21. The cylinder bottom 18 and the cylinder cover 22 are respectively located at the two ends of the cylinder body 19. The cylinder bottom 18 is hinged to the cross plate. The piston 20 is located in the cylinder body 19. One end of the piston rod 21 is hinged to the first support plate 15, and the other end passes through the cylinder cover 22 and is connected to the piston 20.

[0054] The driving mechanism provided in this embodiment is a hydraulic cylinder. The piston 20 located in the cylinder body 19 divides the cylinder body 19 into a rodless chamber and a rod chamber. A liquid inlet and a liquid discharge port are provided on the cylinder body 19. The liquid inlet is connected to the rodless chamber, and the liquid discharge port is connected to the rod chamber. When it is necessary to drive the piston rod 21 to extend, hydraulic medium is transported into the cylinder body through the liquid inlet, thereby driving the piston 20 to extend in the cylinder body 19, pushing the hatch cover support block 5 to move upward, and installing the airbag hatch cover into the airbag cabin.

[0055] The piston rod 21 includes a first telescopic section and a second telescopic section, the first telescopic section is connected to the piston 20, the second telescopic section is hinged to the first support plate 15, annular grooves are provided on the end surfaces of the first telescopic section and the second telescopic section facing each other, an adjusting ring 23 is also provided between the first telescopic section and the second telescopic section, and connecting balls located in the annular grooves are provided on both sides of the adjusting ring 23; active cavities are provided in the first telescopic section and the second telescopic section, an adjusting rod 24 with an outer diameter the same as an inner diameter of the active cavity is provided in the cavity, and the adjusting ring 23 is threadedly connected to the piston rod 21; a step hole communicating with the active cavity is also provided on the piston 20, a blocking block 28 is provided in the step hole, and a first elastic member 26 connected to the adjusting rod 24 is provided on the blocking block 28; a through hole 27 communicating with the active cavity is also provided on the first telescopic section of the piston rod 21.

[0056] Since airbag cabins of different shapes require different pressures during installation, in order to avoid damage to the cabin cover and the drone caused by excessive pressure generated by the driving mechanism, an adjusting rod 24, a first elastic member 26 and a blocking block 28 are provided in the piston rod 21 of this embodiment, and an adjusting ring 23 is sleeved on the adjusting rod 24, and the adjusting ring 23 and the adjusting rod 24 are connected by threads. In this way, when the adjusting ring 23 is rotated, the adjusting rod 24 can be driven to move in the active cavity of the first telescopic section under the action of the threads, and the distance between the adjusting rod 24 and the blocking block 28 is changed, thereby realizing the adjustment of the elastic force of the first elastic member 26. Therefore, in actual applications, when installing airbag cabin covers of different shapes, it is only necessary to use the adjusting ring 23 to adjust the position of the adjusting rod 24 in the active cavity, thereby realizing The elastic force of the first elastic member 26 is adjusted. When in use, hydraulic medium is transported into the cylinder body 19 through the liquid inlet, and the piston 20 is driven to move under the action of the hydraulic medium, so that the hatch cover support block 5 moves upward, pressing the airbag hatch cover into the airbag cabin. When the pressure in the cylinder body 19 is greater than the elastic force of the first elastic member 26, the hydraulic medium in the rodless cavity will push the blocking block 28 to compress the first elastic member 26. At this time, the hydraulic medium that subsequently enters the rodless cavity will enter the active cavity through the step hole, and then the hydraulic medium will enter the rod cavity through the through hole 27. Therefore, by adjusting the elastic force of the first elastic member 26, the maximum pressure value of the driving mechanism can be changed, thereby avoiding the driving mechanism from exerting excessive pressure on the hatch cover support block 5, thereby achieving the purpose of protecting the hatch cover and the drone during assembly.

[0057] The second telescopic section is further provided with a telescopic rod 25 , which penetrates into the active cavity, and a scale is further provided on the surface of the telescopic rod 25 .

[0058] Since the outer diameter of the adjusting rod 24 is consistent with the inner diameter of the active cavity in the second telescopic section, when the adjusting rod 24 moves in the second telescopic section, the air in the second telescopic section will be compressed, thereby changing the extension amount of the telescopic rod 25 in the second telescopic section. Therefore, the compression amount of the first elastic member 26 can be determined by observing the scale on the telescopic rod 25.

[0059] A rotating rod 30 and a connecting block 31 are also provided between the adjusting rod 24 and the first elastic member 26. The outer diameter of the connecting block 31 is consistent with the inner diameter of the movable cavity. The first elastic member 26 is connected to the connecting block 31. A third bearing is provided in the connecting block 31. One end of the rotating rod 30 is connected to the adjusting rod 24, and the other end is connected to the third bearing.

[0060] Since the adjusting rod 24 is arranged to adjust the elastic force of the first elastic member 26 by rotating, in order to prevent the first elastic member 26 from being worn when the adjusting rod 24 rotates, a rotating rod 30 and a connecting block 31 are also arranged between the first elastic member 26 and the adjusting rod 24. When the adjusting rod 24 rotates, the rotating rod 30 is driven to rotate in the connecting block 31, thereby avoiding the wear of the first elastic member 26 caused by the contact between the adjusting rod 24 and the first elastic member 26.

[0061] The end surface of the piston 20 facing the first telescopic section is provided with a blind hole whose inner diameter is consistent with the outer diameter of the first telescopic section, and a limiting groove is provided on the inner wall of the blind hole. The first telescopic section is located in the blind hole, and a limiting block located in the limiting groove is also provided on the side wall of the first telescopic section. An airbag 29 is provided in the blind hole; the step hole includes a first connecting hole and a second connecting hole connected to each other, and the second connecting hole is connected to the blind hole. The blocking block 28 includes a first blocking rod 32 and a second blocking rod 35 connected to each other, and the first blocking rod 32 is located in the first connecting hole. The inner diameter of the first connecting hole is consistent with the outer diameter of the first blocking rod 32, and the outer diameter of the first blocking rod 32 is smaller than the outer diameter of the second blocking rod 35; a locking groove is also provided on the side wall of the first blocking rod 32, and a second elastic member 33 and a locking block 34 are provided in the locking groove. A locking hole is also provided on the inner wall of the first connecting hole, and the second elastic member 33 is used to push the locking block 34 to be inserted into the locking hole, and the locking hole is connected to the airbag 29.

[0062] In order to prevent the instantaneous pressure in the rodless cavity of the cylinder body 19 from being too high, which would cause the blocking block in the step hole to be opened, a second elastic member and a locking block 34 are provided in the present embodiment. In the initial state, under the elastic force of the second elastic member 33, the locking block 34 is inserted into the locking hole to fix the first blocking rod 32 in the first connecting hole. Even if the instantaneous pressure in the rodless cavity of the cylinder body 19 is relatively high, the first blocking rod 32 cannot be removed from the first connecting hole. When the piston 20 drives the piston rod 21 to press the hatch cover support block 5 into the drone airbag cabin, the hatch cover support block 5 contacts the airbag cabin, and the airbag cabin can press the piston The rod 21 generates a reaction force, forcing the piston rod 21 to retract and squeeze the airbag 29. At this time, the pressure medium in the airbag 29 will enter the locking hole and push the locking block 34 in the locking hole to retract, thereby unlocking the first blocking rod 32. During the installation of the airbag hatch, once the pressure in the cylinder body 19 is greater than the elastic force of the first elastic member 26, the hydraulic medium in the rodless cavity of the cylinder body 19 will push the first blocking rod 32 to move from the first connecting hole, so that the hydraulic medium is finally discharged into the rod cavity of the cylinder body 19 through the through hole 27, thereby preventing the airbag hatch from being damaged due to excessive pressure on the piston rod 21.

[0063] The locking block 34 is provided with a beveled edge. After installation is completed, the blocking block 28 can be pushed back under the action of the first elastic member 26. Under the action of the beveled edge, the locking block 34 protruding outside the first blocking rod 32 can be retracted into the locking groove so that the locking block can smoothly pass through the step surface of the step hole.

[0064] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
