Technical Field

The invention relates to the field of unmanned aerial vehicle distribution, in particular to a cargo handling structure of an unmanned aerial vehicle.

Background

In recent years, with the rapid development of unmanned aerial vehicles and logistics industries, powerful market demands make unmanned aerial vehicle distribution a new hot field. In the process of unmanned aerial vehicle distribution, the problem of containing and unloading goods is a core technical problem in the field, and the two common loading and unloading modes at present mainly comprise a hanging cabin type loading and unloading structure and a goods shelf type loading and unloading structure.

The unmanned aerial vehicle is connected with a warehouse through a rope, goods are placed in the warehouse, and after the goods reach a destination, the rope is directly cut off or directly released from the warehouse, so that unloading is realized; although logically simple, this approach is not desirable for aircraft flight speeds and generally for the delivery of cargo of greater mass, given that the flexible tether connection of the aircraft during flight may affect flight stability. At the same time, the aircraft can only deliver one cargo at a time in this way, which also limits the delivery efficiency. The latter adopts the mode of carrying on the goods shelves on unmanned aerial vehicle aircraft, and this kind of mode compares with the former, can carry out the transportation of the goods of relative heaviness, and stability is also better.

But the current shelf type loading and unloading structure also has certain problems:

1. although the shelf type loading and unloading structure can meet the requirement of simultaneously delivering a plurality of goods by matching the shelf with the pushing mechanism in theory, the shelf type loading and unloading structure still exists in the theoretical conception stage until now, no mature and feasible specific technical scheme exists, and the development of unmanned aerial vehicle delivery is influenced. Although some technical documents disclose some shelf-type loading and unloading structures, such as patent document CN105923163B, the structure is too simple and the degree of automation is poor, which obviously does not meet the demand of distribution by unmanned aerial vehicles.

2. In the process of aerial delivery of unmanned aerial vehicles, in order to ensure the safety of unmanned aerial vehicles, the unmanned aerial vehicles are not suitable to be too close to buildings, so a vertical delivery mode is mostly adopted in the prior art, however, a special unloading device needs to be arranged on a roof or an outdoor open platform, but for most buildings, the outdoor platform is not convenient to install for the house type of each owner household, so the vertical delivery mode is not suitable for directly delivering goods to a user side, and the advantages of rapidness, accuracy and high efficiency of unmanned aerial vehicle delivery cannot be fully played. Therefore, if an unmanned aerial vehicle distribution device capable of realizing lateral cargo delivery can be designed, after the unmanned aerial vehicle flies to the designated position of the building facade, the cargo is directly delivered to a receiving station on the facade of a user or a residence of the user, and the problems are fundamentally solved.

3. In-process of aerial delivery of unmanned aerial vehicle, because different goods have different bulky, in order to improve the commonality of goods delivery, adopt the structure of dismantling the connection between the goods shelves that unmanned aerial vehicle carried on and the unmanned aerial vehicle main part usually. But owing to adopt high altitude construction, the security of aerial delivery has directly been decided to the stability of so goods shelves and unmanned aerial vehicle connection structure, and present traditional connection structure still has certain defect in the security.

After the flight parcel case 3 of bottommost layer is put down, first electric putter 7 resets, drives layer board 8 and stretches into the storehouse body 4 again, and splint 11 withdraws from the storehouse body 4 simultaneously, and flight parcel case 3 on the second layer from last originally forms the support along the gliding of the storehouse body 1 on layer board 8. In order to improve the smoothness of the downward sliding of the flight wrapping box 3, a plurality of hemispherical lubricating salient points 18 are arranged on the inner side wall of the bin body 4, and the lubricating salient points 18 are suitable for the hard flight wrapping box 3 and are not suitable for the relatively flexible flight wrapping box 3 such as corrugated paper. Therefore, the invention can also arrange a downward pushing mechanism on the inner wall of the top of the bin body 1 so as to push the flying parcel boxes 3 downward one by one. As for detecting whether the flying parcel box 3 has been discharged or has slid down to the right, only a corresponding sensor needs to be arranged, and the form is relatively simple and is not described herein again. The supporting control mechanisms are generally symmetrically arranged on two sides of the bin body 4, so that the stability is excellent.

The present invention also differs from the second point in that the unloading zone comprises an unloading chute 19 in the shape of an inverted U, said unloading chute 19 being provided with unloading means for laterally delivering the flying package out of the unloading chute 19. The unloading chute 19 can be formed by directly extending the front and rear sides of the bin body 4 downwards, or can be an independent component which is assembled at the lower part of the bin body 4.

As shown in connection with fig. 1, 4 and 5, the discharge mechanism includes a pendulum assembly and a drive assembly. The swinging assembly comprises two first rotating shafts 20 which are symmetrically arranged at the left side and the right side of the bottom of the unloading groove 19 and extend along the front-back direction, and two ends of each first rotating shaft 20 are arranged on the front side wall and the rear side wall of the unloading groove 19 and are in rotating fit with the unloading groove 19. Both ends of the first rotating shaft 20 are provided with synchronous gears 21, and the synchronous gears 21 at both ends of the first rotating shaft 20 are in transmission connection through a synchronous belt 22, so that synchronous rotation of the two first rotating shafts 20 is realized.

As shown in fig. 1, the swing assembly further includes a delivery plate 23 and four synchronous swing rods 24, the delivery plate 23 and the four synchronous swing rods 24 are located at the upper portion of the unloading slot 19, the upper ends of the four synchronous swing rods 24 are respectively hinged to the front side and the rear side of the left end and the right end of the delivery plate 23, and the lower ends of the four synchronous swing rods 24 are respectively fixedly connected to two ends of the two first rotating shafts 20. The driving component is in transmission connection with one of the first rotating shafts 20 and is used for driving the motion of the swinging component, and the driving component can be a motor connected with the first rotating shaft 20 or other structures which can drive the first rotating shaft 20 and have the same function.

In the use, after unmanned aerial vehicle main part 1 flies to the target site, flight parcel case 3 shipment in the storage area is to delivery board 23 on, and drive assembly drives first pivot 20 action, and first pivot 20 drives synchronous pendulum rod 24 swing, and delivery board 23 of synchronous pendulum rod 4 upper end keeps the level to send out towards the side, directly delivers flight parcel case 3 on it to in the user's hand or directly place on the receipts goods platform on building facade. Compared with the traditional vertical delivery, the unmanned aerial vehicle main body 1 can directly realize hovering and side unloading, and the goods are delivered to the user terminal directly. Meanwhile, the side delivery mode is very suitable for cargo delivery of modern high-rise buildings, vertical face delivery is directly achieved, a special parking apron, a special goods station and the like are not needed, a brand-new direction is provided for unmanned aerial vehicle delivery, and popularization and promotion are facilitated. In addition, the distance between the unmanned aerial vehicle and the building facade can be ensured by the side delivery mode, and the delivery safety is improved.

Considering that during the side delivery process, when the cargo is relatively heavy, the center of the main body 1 of the unmanned aerial vehicle has a larger inclination, and in order to achieve balance and ensure the stability of the flying posture of the main body 1 of the unmanned aerial vehicle, the invention can be better implemented by combining fig. 1, 4 and 5, the unloading mechanism further comprises a counterweight assembly, the counterweight assembly comprises a second rotating shaft 25 which is arranged between the two first rotating shafts 20 and is parallel to the first rotating shafts 20, and two ends of the second rotating shaft 25 are mounted on the bottom plate of the unloading groove 19 through bearings. The counterweight assembly further comprises two counterweight swing rods 26, the lower ends of the counterweight swing rods 26 are fixedly connected with the positions, close to the bearings, of the two ends of the second rotating shaft 25 respectively, and the upper ends of the counterweight swing rods are fixedly connected with the counterweight part 27. A transmission assembly is arranged between the first rotating shaft 20 and the second rotating shaft 25, and the rotating directions of the first rotating shaft 20 and the second rotating shaft 25 are opposite. The present invention, through the arrangement of the weight assembly, when the first rotating shaft 20 rotates, can drive the second rotating shaft 25 to rotate reversely, and the second rotating shaft 25 drives the weight part 27 to deflect in the opposite direction to the delivering plate 23 and the synchronizing swing rod 24 through the weight swing rod 26, as shown in fig. 6 and 7, that is, the deflection state occurs. The inclined weight part 27 can effectively counteract the influence of the weight of the delivery plate 23, the synchronous swing rod 24 and the flying package box 3 on the center, and maintain the stability of the flying attitude.

The specific structure of the transmission assembly is many as long as the reverse rotation between the first rotating shaft 20 and the second rotating shaft 25 can be realized, as shown in fig. 5, the transmission assembly includes a first transmission wheel 28 disposed between the first rotating shaft 20 and the second rotating shaft 25, and shaft rods at two ends of the first transmission wheel 28 are mounted on a pair of ear plates 29 on the bottom plate of the unloading slot 19 and form a rotating fit with the ear plates 29. The first transmission wheel 28 is in transmission connection with a second transmission wheel 30 arranged on the second rotating shaft 25 through a transmission belt 31. A first transmission gear 32 is further disposed on the shaft rod at one end of the first transmission wheel 28, and the first transmission gear 32 is meshed with a second transmission gear 33 disposed on the first rotation shaft 20. The transmission path of the device comprises a second rotating shaft 25, a second transmission wheel 30, a transmission belt 31, a first transmission wheel 28, a first transmission gear 32, a second transmission gear 33 and a first rotating shaft 20 in sequence.

As for the driving assembly, the driving rod assembly of the present invention preferably drives the second rotating shaft 25 in order to make the center of gravity of the overall apparatus closer to the center, and the second rotating shaft 25 is designed at the center of the bottom plate of the unloading slot 19. As shown in fig. 4 and 5, the driving assembly includes a discharging motor 34 fixedly disposed on the bottom surface of the bottom plate of the discharging chute 19, an output end of the discharging motor 34 upwardly passes through the bottom plate of the discharging chute 19, and an end portion thereof is provided with a first bevel gear 35, and the first bevel gear 35 is engaged with a second bevel gear 36 fixedly disposed on the second rotating shaft 25.

In order to further improve the delivery radius of the swinging assembly and the universality of the counterweight assembly, the invention may be better that a hydraulic oil tank 37 is further fixedly arranged on the bottom surface of the bottom plate of the unloading groove 19, the synchronous swing rod 24 and the counterweight swing rod 26 are both hydraulic telescopic rods, and the hydraulic telescopic rods are communicated with the hydraulic oil tank 37 through oil pipelines. In this way, the delivery radius can be changed by changing the length of the synchronization pendulum 24, and the center of gravity can be more effectively adjusted by changing the length of the counterweight pendulum 26. As for how to pump the hydraulic oil in the hydraulic oil tank 37 into the hydraulic telescopic rod to achieve the telescopic function, the invention is a conventional choice in the prior art, and the invention does not describe the function, and a designer only needs to select proper hydraulic pumps, distribution valves, reversing valves and other accessories according to actual needs.

The counterweight component 27 can select a counterweight component with fixed weight, but under the distribution working condition with larger cargo weight difference, the flexibility of the counterweight component is insufficient by simply depending on the extension and contraction of the counterweight swing rod 26 to change the gravity center, so the invention better practices that the counterweight component 27 is a counterweight oil cylinder, and the counterweight oil cylinder is communicated with the hydraulic oil tank 37 through an oil pipeline. The change of the total weight of the heavy oil distribution cylinder is realized by pumping the hydraulic oil in the hydraulic oil tank 37 into the heavy oil distribution cylinder, so that the adjustment margin is larger.

As for how to detect whether there is a flying parcel box 3 on the delivery board 23, the present invention may be that the upper surface of the delivery board 23 is provided with a weight sensor 38, and the weight information difference collected by the weight sensor 38 is used for distinguishing. It is also possible to provide a light-sensitive sensor to distinguish the presence of the flying package 3 on the delivery board 23 by the acquisition of the light signal. Besides, in order to further improve the stability, the delivery plate 23 is further provided with an adsorption locking assembly, and the adsorption locking assembly can be directly constructed by adopting a sucking disc or an electromagnet matched with an iron sheet on the flying package box 3.

A plurality of vertical screw rods 42 are uniformly arranged on the first connecting disc 39 around the center and are matched with locking nuts 43, a plurality of rod holes are formed in the second connecting disc 40 corresponding to the screw rods 42, and the screw rods 42 penetrate through the rod holes and are locked with the second connecting disc 40 through the locking nuts 43.

More importantly, the connecting mechanism further comprises a reinforcing assembly, as shown in fig. 9, which is a schematic structural diagram of the reinforcing assembly in a top view, the reinforcing assembly is composed of two T-shaped reinforcing rods 44, the end portions of two side rods of the reinforcing rods 44 are provided with C-shaped first bayonets 45, the screw rod 42 is provided with a first side groove 46 matched with the first bayonets 45, and the first bayonets 45 are clamped in the first side groove 46.

Meanwhile, the two T-shaped reinforcing rods 44 connect the position of the first bayonet 45 with the position of the second bayonet 47, and stress is further distributed to the surface of the whole second connecting disc 40 through the reinforcing rods 44, so that the stress condition is greatly improved, deformation and looseness are not prone to occurring, the safety is excellent, and the high-altitude distribution device is particularly suitable for high-altitude distribution, and on the basis, the rubber pads are arranged on the upper surface of the second connecting disc 40, so that the connection is tighter. When the loading and unloading goods shelves with different sizes need to be replaced, the locking nut 43 is unscrewed.
