Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicles, and particularly relates to a hanging device for unmanned aerial vehicle mounting. BACKGROUND

[0002] Common unmanned aerial vehicle mounting structures include rigid connection hangers, flexible connection hangers and adjustable hangers. When a hanger with flexible or single-point connection is used, the mounted object is prone to large swing under the impact of airflow in high altitude or complex terrain, which interferes with the flight attitude of the unmanned aerial vehicle, increases the control difficulty, and even causes the unmanned aerial vehicle to crash, and the equipment may be damaged.

[0003] In actual use, most of the time, rigid connection hangers are used for air transportation, and the mounting of the mounted object is achieved by mechanical locking on the rigid connection hanger. Special lock buckles, card slots and other structures are arranged on the hanger, and the corresponding connecting parts are arranged at the corresponding positions of the mounted object. The mounted object is safe and stable, but when the unmanned aerial vehicle travels unevenly, the mounted object is prone to damage due to unevenness.

[0004] Therefore, when the hanger is used, it is difficult to balance the stable operation of the unmanned aerial vehicle and the stable transportation of the mounted object after the installation of the mounted object, and flight risk or damage risk of the mounted object is prone to exist.

[0005] In the above-mentioned rigid connection hanger, a large number of screws and the like are used as connecting pieces for assembly and fixation. Therefore, during installation, the operator needs to use tools to screw the screws many times, and the operation process is complicated, which consumes a lot of time and labor. Moreover, when the mounted object needs to be frequently replaced or the hanger needs to be maintained, the complicated installation and disassembly method seriously affects the work efficiency.

[0006] Meanwhile, when the existing hanger and the mounted object are closed by the lock buckle or clamped by the card slot for disassembly, the disassembly between the hanger and the mounted object completely depends on the connection point when quick connection and release are needed. When the emergency disassembly of the connection point fails, the quick connection and release of the mounted object are difficult to achieve. Moreover, since the connection and release operation of some hangers needs multiple steps, and the lock buckle, card slot and other structures are involved in part of the operation, manual operation may be needed on site, which cannot meet the quick response demand in emergency situations or high-efficiency operation scenarios. SUMMARY

[0007] In view of the deficiencies in the prior art, the present application provides a hanging device for unmanned aerial vehicle mounting to solve the problem that the existing hanger is difficult to balance the stable operation of the unmanned aerial vehicle and the stable transportation of the mounted object after the installation of the mounted object.

[0008] In order to achieve the above object, the basic scheme of the present application is as follows: a hanging device for unmanned aerial vehicle mounting, comprising: The swing damping hanging frame is detachably connected with the unmanned aerial vehicle. The emergency throwing assembly is detachably connected with the mounting object, and is located between the swing damping hanging frames. The connecting assembly comprises: The end of the swing damping hanging frame is rotationally connected with the peripheral surface of the mounting rod. The joint bearing is coaxially rotationally installed on the mounting rod, and the peripheral surface of the joint bearing is fixedly connected with the emergency throwing assembly. The plurality of nuts are locked on the end of the mounting rod, and the joint bearing and the swing damping hanging frame are located between the nuts.

[0009] The technical principle of the present application is that, in use, the mounting object is connected with the emergency throwing assembly, and when the mounting object swings during the transfer and transportation of the unmanned aerial vehicle, the swing of the mounting object can be transmitted to the swing damping hanging frame through the emergency throwing assembly and the connecting assembly, at this time, the swing of the mounting object can be stably and uniformly transmitted to the swing damping hanging frame through the mounting rod and the joint bearing, and the swing damping hanging frame can eliminate the swing of the mounting object under the action of the original inertia, thereby eliminating the influence of the swing of the mounting object on the unmanned aerial vehicle as much as possible, and ensuring the stability, safety and reliability during the transportation of the mounting object.

[0010] When an emergency situation occurs and the mounting object needs to be air-dropped or thrown, the emergency throwing assembly can quickly loosen the mounting object, so that the mounting object is quickly air-dropped or thrown, and the emergency situation has corresponding processing capacity.

[0011] Further, the profile of the swing damping hanging frame is in the shape of a prism or a pyramid, and the end of the swing damping hanging frame with a smaller cross-sectional profile is rotationally connected with the mounting rod.

[0012] Through the above arrangement, the swing damping hanging frame in the shape of a prism or a pyramid can uniformly and widely disperse the tension generated during the swing of the mounting object, and this part of the force is transmitted to the unmanned aerial vehicle through the swing damping hanging frame, which can further reduce the influence of the swing of the mounting object on the unmanned aerial vehicle.

[0013] Further, the present application further comprises: The plurality of lifting rings are installed at the end of the swing damping hanging frame away from the mounting rod. The plurality of length-adjustable pull ropes are connected with the lifting rings at one end, and are connected with the unmanned aerial vehicle at the other end.

[0014] Through the above setting, when the load is mounted on the emergency throwing assembly, the length of the pull rope can be adjusted according to the equivalent swing center line of the load, so that the equivalent swing center line of the load is located near the vertical gravity center of the unmanned aerial vehicle, which can effectively reduce the swing of the load during transfer transportation; so that the load is swung, because the gravity centers of the load and the unmanned aerial vehicle are located on the same vertical line, the influence of the load on the stable flight of the unmanned aerial vehicle can be reduced; at the same time, the anti-swing hanger cooperates with the pull rope, and the tension generated during the swing of the load is dispersed by the anti-swing hanger and the pull rope, so that the swing of the load is fully eliminated.

[0015] Further, the emergency throwing assembly comprises: a plurality of emergency throwers; a decoupler adapter, one end of the decoupler adapter is fixedly connected with the knuckle bearing, and the other end of the decoupler adapter is fixedly connected with the plurality of emergency throwers; a connecting buckle connected with the load, the connecting buckle is detachably connected with the emergency thrower.

[0016] Through the above setting, the decoupler adapter can stably connect the plurality of emergency throwers, so that the plurality of emergency throwers can be stably installed in the hanging device, and the use of the plurality of groups of emergency throwers increases the maximum mass of the single hanging device during mounting, so that the hanging device can mount large goods.

[0017] Further, the emergency thrower comprises: a first mounting plate; a second mounting plate, the second mounting plate is arranged in parallel with the first mounting plate; two rotating clamping jaws, the two rotating clamping jaws are detachably connected with the connecting buckle after being combined, and the rotating clamping jaws are rotatably installed between the surfaces of the first mounting plate and the second mounting plate; a rotating control motor, the rotating control motor is fixedly installed on the surface of the second mounting plate; a rotating shaft, the rotating shaft passes through the first mounting plate and the second mounting plate and is connected with the power output end of the rotating control motor, and the rotating shaft is rotatably connected with the first mounting plate and the second mounting plate; a cam, the cam is fixedly installed on the rotating shaft; a jacking rod, the jacking rod is vertically slidably installed between the surfaces of the first mounting plate and the second mounting plate, and the end surface of the jacking rod abuts against the wheel surface of the cam; a limiting rod, the limiting rod is rotatably installed between the surfaces of the first mounting plate and the second mounting plate, one end of the limiting rod abuts against the end of the jacking rod away from the cam, and the other end of the limiting rod is provided with an abutting groove which can abut against the end of the rotating clamping jaw away from the connecting buckle; When the top rod abuts against the wheel surface close to the center of the cam, the rotating clamping jaws are in the abutting state with the abutting grooves, and the two rotating clamping jaws are in the buckling state; when the top rod abuts against the wheel surface away from the center of the cam, the rotating clamping jaws are in the non-abutting state with the abutting grooves, and the two rotating clamping jaws can be separated around the rotating part.

[0018] Through the above setting, when the unmanned aerial vehicle delivers the hanging object to the destination, the rotation of the rotating shaft is controlled by rotating the control motor, so that the lower end of the top rod abuts against the position farthest from the rotating shaft axis of the cam wheel surface, the top rod lifts the clamping block, the clamping block pushes the end of the limiting rod to move up, at this time the upper end of the rotating clamping jaw is loosened by the abutting groove on the limiting rod, and then the shackle can be taken out from the loosened two rotating clamping jaws; or, the shackle is directly disassembled from the disassembled shackle, so that the connecting buckle is disassembled from the rotating clamping jaw; or, the hanging object is disassembled from the connecting buckle; the above three ways can quickly and stably take down the hanging object, and the disassembly is flexible and convenient.

[0019] Further, the emergency thrower further comprises: The thrower shell, the first mounting plate, the two rotating clamping jaws, the second mounting plate, the rotating control motor, the rotating shaft, the cam, the top rod and the limiting rod are all installed in the thrower shell, the first mounting plate and the second mounting plate are fixedly connected with the thrower shell, and the unhooker adapter is connected with the thrower shell, the first mounting plate and the second mounting plate.

[0020] Through the above setting, the thrower shell can protect the first mounting plate, the two rotating clamping jaws, the second mounting plate, the rotating control motor, the rotating shaft, the cam, the top rod and the limiting rod; the unhooker adapter can be stably connected through the thrower shell, the first mounting plate and the second mounting plate, and the stress on the local part of the emergency thrower during hanging is reduced.

[0021] Further, the emergency thrower further comprises: The limiting support piece abuts against the outer wall of the rotating clamping jaw close to one end of the limiting rod, is located between the rotating connection point between the rotating clamping jaw and the first mounting plate and the limiting rod, and is located at the side of the rotating clamping jaw away from the other rotating clamping jaw; The limiting support shaft is installed between the surfaces of the first mounting plate and the second mounting plate; The supporting block is coaxially installed on the limiting support shaft, and the limiting support piece is buckled on the supporting block.

[0022] Through the above setting, when the two rotating clamping jaws are loosened, the limiting support at the outer side of the two rotating clamping jaws can support and limit the outer side of the rotating clamping jaws, so that the upper end of the outer side of the rotating clamping jaws is prevented from being completely separated from the abutting groove; when the rotating control motor continues to control the rotation of the shaft, and the lower end of the top rod slides to the local part of the cam surface close to the center of the shaft again, the top end of the rotating clamping jaw is facilitated to be pushed back into the abutting groove by the limiting support piece again for locking.

[0023] Further, the number of emergency throwers is two, and the two emergency throwers are oppositely arranged and symmetrically arranged along the vertical center planes of the two first mounting plates. The end portions of the shafts in the two emergency throwers are fixedly connected.

[0024] Through the above setting, when the rotating control motor of one of the emergency throwers is damaged or cannot be controlled, emergency air drop or throwing is needed, and only the rotating control motor in the remaining emergency thrower needs to be operated. At this time, since the shafts in the two emergency throwers are coaxially fixedly connected, the intact rotating control motor can synchronously drive the two shafts to rotate, and the corresponding two rotating clamping jaws can still be in a loosened state, so that the whole mounted object and connecting fastener can be automatically separated, and emergency air drop or throwing can be realized.

[0025] Further, a groove is arranged on the end of the shaft away from the rotating control motor, and the groove of the shaft and the groove at the other end of the shaft are clamped and installed after the end of the shaft away from the rotating control motor penetrates through the first mounting plate.

[0026] Through the above setting, the end portions of the shafts in the two groups of emergency throwers are aligned and connected through the grooves, the synchronism of the two connected shafts is improved, and the installation and connection operation of the end portions of the two shafts is convenient and rapid.

[0027] Further, the connecting fastener comprises: A release buckle, which is in the shape of a "D", and the horizontal section of the release buckle can be hung to between the two rotating clamping jaws; A universal buckle, which is in the shape of an "8", and the universal buckle is connected with the release buckle and connected with the mounted object.

[0028] Through the above setting, the mounting and throwing of the mounted object are realized through the release buckle and the universal buckle respectively, and the connection and cooperation of the universal buckle and the mounted object are not affected when the mounted object is thrown through the release buckle, so that the mounted object is not easy to scatter, and the connecting fastener is not easy to be lost.

[0042] Meanwhile, as shown in Figure 2 , Figure 3 and Figure 4 , the limiting support sheet 210 abuts against the outer wall of the rotating clamping jaw 202 close to one end of the limiting rod 208, and is located between the rotating connection point of the rotating clamping jaw 202 and the first mounting plate 201 and the limiting rod 208, and is located at the side of the rotating clamping jaw 202 away from the other rotating clamping jaw 202; the limiting support shaft 211 is installed between the surfaces of the first mounting plate 201 and the second mounting plate 203; the support block 212 is coaxially installed on the limiting support shaft 211, and the limiting support sheet 210 is clamped and installed on the support block 212.

[0043] As shown in Figure 2 , Figure 3 and Figure 4As shown in the figures, the first mounting plate 201, the two rotating clamping jaws 202, the second mounting plate 203, the rotating control motor 204, the rotating shaft 205, the cam 206, the top rod 207, the limiting rod 208, the limiting support sheet 210, the support block 212 and the limiting support shaft 211 are all installed in the thrower shell 214, the first mounting plate 201 and the second mounting plate 203 are fixedly connected with the thrower shell 214, the decoupler adapter 3 is connected with the thrower shell 214, the first mounting plate 201 and the second mounting plate 203; the two sets of limiting rods 208, the two sets of limiting support sheets 210 and the two sets of limiting support shafts 211 are symmetrically arranged along the vertical center line of the surface of the first mounting plate 201; the axis of the rotating shaft 205 is horizontally arranged and parallel to the rotating axes of the limiting rods 208, the limiting support sheets 210 and the limiting support shafts 211.

[0044] As shown in the figures, Figure 1 , Figure 2 and Figure 3 , the number of the emergency throwers 20 is two, the two emergency throwers 20 are oppositely arranged, the two emergency throwers 20 are symmetrically arranged along the vertical center planes of the two first mounting plates 201, and the end portions of the rotating shafts 205 in the two emergency throwers 20 are fixedly connected.

[0045] As shown in the figures, Figure 1 , Figure 2 and Figure 3 , the connecting fastener 4 includes a release buckle 41 and a universal buckle 42, the release buckle 41 is in the shape of "D", and the horizontal section of the release buckle 41 can be hung to between the two rotating clamping jaws 202; the universal buckle 42 is in the shape of "8", the universal buckle 42 is connected with the release buckle 41, and the universal buckle 42 is connected with the hanging object.

[0046] In use, the hanging device for unmanned aerial vehicle hanging in the embodiment is used to install the hanging object to be transferred and transported on the universal buckle 42, connect the upper end of the pull rope 63 with the hanging point at the bottom of the unmanned aerial vehicle, and realize the connection between the anti-swing hanging rack 1 and the unmanned aerial vehicle; in this process, the length of the pull rope 63 can be adjusted according to the equivalent swing center line of the hanging object, so that the equivalent swing center line of the hanging object is located near the vertical gravity center of the unmanned aerial vehicle, which can effectively reduce the swing of the hanging object during the transfer and transportation; at the same time, when the hanging object swings, since the gravity centers of the hanging object and the unmanned aerial vehicle are basically located on the same vertical line, the influence of the hanging object on the stable flight of the unmanned aerial vehicle can be reduced.

[0047] When the unmanned aerial vehicle takes off, the pyramid-shaped sway elimination hanging bracket 1 cooperates with the pull rope 63 to uniformly and widely disperse the pulling force generated in the swinging process of the hanging load, and then the pulling force is transmitted to the unmanned aerial vehicle through the sway elimination hanging bracket 1 and the pull rope 63; in this process, the sway elimination hanging bracket 1 can eliminate the swing of the hanging load under the action of the original inertia, and can eliminate the influence of the swing of the hanging load on the unmanned aerial vehicle as much as possible, thereby ensuring the stability, safety and reliability of carrying the hanging load.

[0048] At the same time, the sleeve 11 on the sway elimination hanging bracket 1 can rotate relative to the mounting rod 51, and the joint bearing 52 can stably connect the emergency throwing device 20 and the sway elimination hanging bracket 1, so that the connection and installation of the hanging load are stable; and since the power transmission between the shackle 41, the universal buckle 42, the emergency throwing device 20 and the unhooking device adapter 3 is linear, it is convenient to stably transmit the swing of the hanging load to the sway elimination hanging bracket 1 and the pull rope 63 for elimination, thereby further improving the stability of carrying.

[0049] When the unmanned aerial vehicle delivers the hanging load to the destination, the unmanned aerial vehicle can directly land, and after placing the hanging load, the control motor 204 is rotated to control the rotation of the shaft 205, so that the lower end of the jacking rod 207 is located at the position farthest from the shaft center of the cam 206, the jacking rod 207 jacks up the clamping block 213, the clamping block 213 pushes the end of the limiting rod 208 to move upward, at this time the upper end of the rotating jaw 202 is loosened at the abutting groove 209 on the limiting rod 208, and then the shackle 41 can be taken out from the two loosened rotating jaws 202; or, the shackle 41 is separated from the rotating jaw 202 by directly disassembling the shackle 41; or, the hanging load is disassembled from the universal buckle 42; the above three methods can quickly and stably remove the hanging load, and are flexible and convenient to disassemble.

[0050] When air dropping or throwing is needed, the control motor 204 is rotated to control the rotation of the shaft 205, so that the lower end of the jacking rod 207 is located at the position farthest from the shaft center of the cam 206, the jacking rod 207 jacks up the clamping block 213, the clamping block 213 pushes the end of the limiting rod 208 to move upward, at this time the upper end of the rotating jaw 202 is loosened at the abutting groove 209 on the limiting rod 208, and then the hanging load is automatically separated from the two loosened rotating jaws 202 under the action of its own gravity, and the air dropping or throwing can be accurately realized.

[0051] When one of the rotating control motors 204 of the emergency thrower 20 is damaged or unable to control the response, an emergency air drop or throw is needed, and only the rotating control motor 204 in the remaining emergency thrower 20 needs to be operated. At this time, since the two rotating shafts 205 in the two emergency throwers 20 are coaxially fixedly connected, the intact rotating control motor 204 can synchronously drive the two rotating shafts 205 to rotate, and the two rotating clamps 202 can still be in a relaxed state, facilitating the automatic disengagement of the mounting object and the connecting fastener 4 as a whole, and enabling the emergency air drop or throw to be realized.

[0052] When the two rotating clamps 202 are relaxed, the limiting support located outside the two rotating clamps 202 can support and limit the outside of the rotating clamps 202, so as to avoid the upper end of the outside of the rotating clamps 202 from being completely disengaged from the abutting groove 209. When the rotating control motor 204 continues to control the rotating shaft 205 to rotate, and the lower end of the jacking rod 207 again slides to the local part of the cam 206 wheel surface close to the center of the rotating shaft 205, the jacking rod 207 drives the clamping block 213 and the end of the limiting rod 208 to move downward. At this time, the top end of the rotating clamp 202 is again limited to the abutting groove 209 for locking. In this process, the cylindrical cam 206 is eccentrically arranged on the rotating shaft 205. When the jacking rod 207 slides along the wheel surface of the cam 206, the range of the wheel surface of the cam 206 close to the center of the rotating shaft 205 is greater than the range of the wheel surface of the cam 206 away from the center of the rotating shaft 205. When the rotating shaft 205 rotates one revolution, the period during which the top end of the rotating clamp 202 is abutted into the abutting groove 209 is greater than the period during which the top end of the rotating clamp 202 is released from the abutting groove 209, so that the mounting object can be stably mounted during the conveying process, and the two rotating clamps 202 can be stably clamped.

[0053] When the mounting object is mounted on the emergency thrower 20, a single set of emergency thrower 20 can mount a mounting object of 200 kg, and two sets of emergency throwers 20 can simultaneously mount a mounting object. The cooperation of the two sets of emergency throwers 20 increases the maximum mass of the single hanging device during mounting, and thus large cargo can be mounted. The two sets of emergency throwers 20 ensure the reliability of transportation. The cooperation of the two sets of emergency throwers 20 enables the single emergency thrower 20 to also have the function of emergency throwing, so as to cope with some unexpected situations and improve the use reliability of the hanging device.

[0054] When the hanging device is maintained, the repair points can be directly judged from the outside of each structure such as the shackle 41, the universal buckle 42, the mounting rod 51, the joint bearing 52, the nut 53, the lifting ring 60, the screw rod 61 and the fixing nut 62, so as to improve the maintenance efficiency. At the same time, the connection points are less associated with each other, can be repaired in a targeted manner, can effectively reduce the position of the screw nut 53 and other structures, can improve the maintenance efficiency and reduce the maintenance cost.

[0055] Example 2 The differences between Example 2 and Example 1 are basically as shown in the appendix. Figure 5 As shown, the rotating shaft 205 includes an output main shaft 215, a connecting shaft 225, an internal gear 235, and an external gear meshing with the internal gear 235. One end of the output main shaft 215 is integrally formed with the power output end of the rotation control motor 204; the external gear is integrally formed on the other end of the output main shaft 215; the cam 206 is eccentrically mounted on the connecting shaft 225; the internal gear 235 is integrally formed on the end of the connecting shaft 225 near the output main shaft 215; and the other end of the connecting shaft 225 is fixedly connected to the end of the connecting shaft 225 in the adjacent emergency thrower 20.

[0056] like Figure 5 As shown, the end of the connecting shaft 225 away from the output spindle 215 is provided with a cross groove, which can be fitted into the cross grooves of the two connecting shafts 225.

[0057] like Figure 5 As shown, the cam 206 and the internal gear 235 are integrally formed, and the internal gear 235 is located between the first mounting plate 201 and the second mounting plate 203.

[0058] In addition, a rubber ring 245 is coaxially tensioned and installed at the connection of the two connecting shafts 225, and the rubber ring 245 covers the circumference of the "+" groove of the connecting shaft 225.

[0059] In this embodiment, the sling device for drone mounting facilitates segmented repair or replacement of the output main shaft 215 and the connecting shaft 225 during maintenance. When the rotation control motor 204 is damaged, repair can be performed by simply disassembling the launcher housing 214 and the rotation control motor 204, without needing to disassemble a series of structures such as the first mounting plate 201, the second mounting plate 203, the connecting shaft 225, and the top rod 207, which can effectively improve maintenance efficiency.

[0060] Meanwhile, when installing and connecting the output spindle 215 and the connecting shaft 225, internal gears 235 are used to ensure precise fit and stable power transmission between the output spindle 215 and the connecting shaft 225. When adjusting the synchronous clamping or synchronous release cycle of the rotating jaws 202 in the two sets of emergency throwers 20, it is only necessary to adjust the rotating connecting shaft 225 to drive the cam 206 to rotate. Then, the internal gear 235 on the connecting shaft 225 is engaged with the external gear on the output spindle 215, making the clamping and installation adjustment of the rotating jaws 202 convenient and quick, and also improving the synchronization of the two sets of emergency throwers 20.

[0061] Meanwhile, when connecting the ends of the two connecting shafts 225 in the two sets of emergency throwers 20, the "cross" recesses of the two connecting shafts 225 can be inserted and fitted with each other, the fitting installation is stable and reliable, and the synchronization of the two sets of rotating clamping jaws 202 when a single emergency thrower 20 is started is improved. At this time, due to the setting of the rubber ring 245, the connection of the ends of the two connecting shafts 225 can be reinforced, and the probability of horizontal sliding and falling out of the connecting shaft 225 is reduced. At the same time, it can block the dust at the ends of the two connecting shafts 225, and facilitate the two connecting shafts 225 to maintain good synchronization.

[0062] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
