Specific embodiments

[0034] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0035] Example 1, as shown in Figure 1 and Figure 2As shown in the figure, a suspended unmanned aerial vehicle (UAV) cargo-carrying device includes a UAV 1, a towing rope 2, and a box body 3. The bottom of the UAV 1 is movably connected to the upper end of the towing rope 2, and the upper end of the box body 3 is movably connected to the lower end of the towing rope 2. A baffle 4 is provided on the front side of the box body 3. The bottom wall of the inner surface of the box body 3 is fixedly connected with a jacking mechanism 6. The left, right, and rear side walls of the inner surface of the box body 3 are fixedly connected together with a limiting mechanism 5. The middle part of the rear end of the box body 3 is slidably connected with a sliding mechanism 7. The left and right side walls of the inner surface of the box body 3 are slidably connected together with a lifting mechanism 8.

[0036] When it is necessary to use the UAV 1 to cooperate with the box body 3 for carrying and transporting goods, first, the goods to be transported are sequentially placed on the upper part of the jacking mechanism 6. At the same time, the limiting mechanism 5 provided on the inner surface of the box body 3 cooperates to limit and clamp the goods, automatically adapting to goods of different sizes, and avoiding the situation that the goods are damaged due to offset during transportation. After the box body 3 is filled with goods on its inner surface, the jacking mechanism 6 cooperates to push the goods upward as a whole. During the pushing process, the baffle 4 automatically drops in cooperation with the lifting mechanism 8 to seal the box body 3 as a whole.

[0037] After the sealing is completed, the box body 3 and the UAV 1 are connected through the towing rope 2, and the length of the towing rope 2 can be wound up, which is convenient for the UAV 1 to drive the box body 3 to fly and transport. The towing rope 2 is movably connected to both the UAV 1 and the box body 3. When it is necessary to connect the UAV 1 and the box body 3 with the towing rope 2, the two ends of the towing rope 2 are respectively fastened and fixed to the UAV 1 and the box body 3. When the UAV 1 drives the box body 3 to reach the designated destination, the towing rope 2 is removed, which is convenient for unloading the goods.

[0038] After the goods are transported, the baffle 4 is lifted upward. By cooperating with some structures of the sliding mechanism 7 and the limiting mechanism 5, the goods on the inner surface of the box body 3 can be pushed outwards for a certain distance, which is convenient for the operator to quickly unload the goods and saves the transportation time.

[0039] During the operation of this embodiment, the limiting mechanism 5 can automatically adapt to goods of different sizes for limiting and clamping. On the one hand, it ensures the stability of the goods during transportation and prevents damage caused by shaking or offset. On the other hand, there is no need for manual additional fixation of the goods. At the same time, the cooperation of the lifting mechanism 8 makes the baffle 4 automatically drop, thereby sealing the box body 3. The automated sealing process not only improves the efficiency but also ensures the safety and confidentiality of the goods during transportation. At the same time, the process of pulling the baffle 4 upward can also make some structures of the sliding mechanism 7 and the limiting mechanism 5 work together to push the goods inside the box body 3 outwards for a certain distance, making the process of unloading the goods more convenient and saving the time and physical strength of the operator.

[0040] Embodiment 2. On the basis of Embodiment 1, in order to achieve the effect that the baffle 4 automatically falls to seal the box body 3, the baffle 4 is stretched to cooperate with the push rod 73 and the first push plate 53 to push the goods out a certain distance.

[0041] Refer to Figure 3 , Figure 4 and Figure 6 , a rectangular groove 31 is opened on the rear side wall of the inner surface of the box body 3, a circular hole 35 is opened in the middle of the rear end of the box body 3, rectangular guide rails 32 are fixedly connected to the middle parts of the left and right side walls of the inner surface of the box body 3, guide rods 33 are fixedly connected to the front parts of the left and right side walls of the inner surface of the box body 3, sliding grooves 34 are symmetrically opened at the front end of the box body 3, and a bottom plate 36 is fixedly connected to the bottom end of the box body 3.

[0042] When preparing to use the drone 1 to cooperate with the box body 3 to transport goods, during the process of placing the goods on the inner surface of the box body 3, the goods are limited and clamped through the rectangular groove 31 and the two rectangular guide rails 32 in cooperation with the limiting mechanism 5. At the same time, the baffle 4 slides freely in cooperation with the two sliding grooves 34, which is convenient for sealing or opening the whole box body 3.

[0043] Refer to Figure 6 , the limiting mechanism 5 includes a plurality of second springs 54 fixedly connected to the front side wall of the inner surface of the rectangular groove 31, a first push plate 53 is fixedly connected to the plurality of second springs 54 together, and a plurality of first springs 52 are fixedly connected to the left and right side walls of the inner surface of the box body 3, and a limiting plate 51 is fixedly connected to the plurality of first springs 52 on the same side together.

[0044] Specifically, when the goods are sequentially placed inside the box body 3, the goods will compress the first springs 52 by pressing the limiting plates 51 at the left and right ends, so that the plurality of first springs 52 on both sides cooperate with the limiting plates 51 to clamp and limit the goods. At the same time, during transportation, the plurality of first springs 52 cooperate with the limiting plates 51 to clamp the goods, avoiding the situation that the goods are damaged due to tilting.

[0045] There are elastic rollers inside the above-mentioned plurality of first springs 52 to limit the first springs 52. When the limiting plate 51 presses the first spring 52, the elastic rollers are compressed at the same time. At the same time, the elastic rollers on both sides cooperate with the first springs 52 and the limiting plates 51 to jointly clamp and limit the goods.

[0046] At the same time, during the process of placing the goods on the inner surface of the box body 3, the lifting mechanism 8 cooperates to push the first push plate 53 backward, so that the plurality of second springs 54 are compressed at the same time. At this time, the front end of the first push plate 53 is flush with the rear side wall of the inner surface of the box body 3.

[0047] Refer to Figure 5, the lifting mechanism 6 includes a limit tube 61 fixedly connected to the middle of the bottom wall of the inner surface of the box body 3. The front side of the upper end of the bottom plate 36 is fixedly connected with a cylinder 63. The bottom wall of the inner surface of the cylinder 63 and the bottom end of the limit tube 61 are jointly fixedly connected with a pipeline 62. A second push plate 64 is slidably connected to the inner surface of the cylinder 63. A one-way valve 621 is fixedly connected to the inner surface of the pipeline 62 located at the bottom wall of the inner surface of the cylinder 63. The front side of the upper end of the limit tube 61 is fixedly connected with an air outlet valve 611.

[0048] The above one-way valve 621 is a conventional design in the prior art, and its purpose is to control the one-way flow of air.

[0049] When placing goods on the inner surface of the box body 3, place the goods on the upper end of the limit tube 61. When the inner surface of the box body 3 is filled with goods, by pushing and pulling the upper end of the second push plate 64 up and down, drive the second push plate 64 to reciprocate up and down along the inner surface of the cylinder 63, and at the same time open the one-way valve 621, so that air can only flow from the inner surface of the cylinder 63 to the inner surface of the pipeline 62 and cannot flow in the reverse direction.

[0050] During the reciprocating movement of the second push plate 64 up and down, the air is pushed from the inner surface of the cylinder 63 to the inner surface of the pipeline 62 through the reciprocating movement of the second push plate 64, and then enters the inside of the limit tube 61, causing the upper end of the limit tube 61 to move upward, and at the same time the whole limit tube 61 is no longer in a compressed state;

[0051] Furthermore, during the upward movement of the upper end of the limit tube 61, the goods at the upper end of the limit tube 61 are pushed to move upward at the same time, and the goods slide upward along the surface of the limit plate 51, and the two limit plates 51 on both sides continue to clamp the goods.

[0052] Refer to Figures 7 - 9 , the lifting mechanism 8 includes a cross plate 81 slidably connected to the outer surfaces of two rectangular guide rails 32. The front end of the cross plate 81 is symmetrically slidably connected with second telescopic rods 83. The front ends of the two second telescopic rods 83 are fixedly connected with clamping blocks 82.

[0053] When the goods inside the box body 3 are driven to move upward by the limit tube 61 and contact the lower end of the cross plate 81, and then during the continuous upward movement of the goods, the cross plate 81 is pushed upward, and then through the cooperation of the two second telescopic rods 83, the two clamping blocks 82 move away from each other.

[0054] Refer to Figure 8 , grooves 811 are respectively opened at the left end and the right end of the cross plate 81. The inner surfaces of the two grooves 811 are respectively slidably connected with the adapted rectangular guide rails 32. Oblique grooves 812 are symmetrically opened at the front end of the cross plate 81. The outer surfaces of the upper ends of the two second telescopic rods 83 are slidably connected with the inner surfaces of the adapted oblique grooves 812. Triangular grooves 821 are respectively opened on the mutually approaching sides of the two clamping blocks 82. The upper parts of the mutually remote sides of the two clamping blocks 82 are respectively slidably connected with the outer surfaces of the adapted guide rods 33.

[0055] Further, referring to Figure 9 , when the cross plate 81 is pushed upward by the goods, the inner surface of the groove 811 slides upward along the outer surface of the rectangular guide rail 32. During the upward movement of the cross plate 81, the second telescopic rod 83 is driven to be stretched through the cooperation of the first inclined groove 812. When the second telescopic rod 83 is stretched to the longest, the cross plate 81 continues to move upward. At this time, the second telescopic rod 83 slides along the inner surface of the first inclined groove 812, driving the clamping block 82 to slide along the outer surface of the guide rod 33 to the side where the two clamping blocks 82 are away from each other.

[0056] Referring to Figure 10 , rectangular plates 41 are fixedly connected to the front sides of the left end and the right end of the baffle 4, and triangular plates 42 are fixedly connected to the lower parts of the rear sides of the left end and the right end of the baffle 4. The inner surfaces of the two triangular plates 42 can be in close contact with the inner surfaces of the adapted triangular grooves 821, and the outer surfaces of the two rectangular plates 41 are slidably connected to the inner surfaces of the sliding grooves 34.

[0057] Further, when the two clamping blocks 82 slide to the position where the inner surface of the triangular groove 821 is not in close contact with the lower end of the triangular plate 42, the pushing of the second push plate 64 is stopped, that is, the upper end of the limiting tube 61 no longer moves. At this time, the goods and the cross plate 81 stop moving. When the lower end of the triangular plate 42 is separated from the inner surface of the triangular groove 821, the whole baffle 4 drops at this time, and the rectangular plates 41 on both sides slide downward along the inner surfaces of the sliding grooves 34, so that the box body 3 can be sealed, making the whole device in a sealed state. At the same time, the limiting plates 51 on both sides of the goods and the first push plate 53 at the rear cooperate together to make the goods in a clamped state during the transportation process.

[0058] Similarly, during the transportation of the goods, the height of the cross plate 81 remains unchanged, and at the same time, the lower end of the cross plate 81 is slightly higher than the upper end of the first push plate 53.

[0059] Furthermore, the box body 3 can be connected to the drone 1 through the towing rope 2, and the drone 1 is activated to operate, so that the box body 3 can be transported to the destination.

[0060] Referring to Figure 11 and Figure 12 , the sliding mechanism 7 includes U-shaped rods 71 symmetrically and fixedly connected to the upper ends of the rectangular plates 41. Telescopic rods 72 are fixedly connected to the rear parts of the two U-shaped rods 71 close to each other. A rectangular block 74 is slidably connected to the two telescopic rods 72 together, and a push rod 73 is fixedly connected to the front end of the rectangular block 74.

[0061] Specifically, when the baffle 4 automatically drops to seal the box body 3, the baffle 4 will drive the two U-shaped rods 71 to drop simultaneously. Then, the two U-shaped rods 71 drive the telescopic rods 72 to slide down along the rectangular block 74 for a certain distance, and then the telescopic rods 72 are compressed until the upper end of the baffle 4 is flush with the upper end of the box body 3 and the baffle 4 no longer moves. At this time, the telescopic rods 72 are compressed to the shortest.

[0062] Refer to Figure 12 Figure 12 , both the left end and the right end of the rectangular block 74 are provided with a first L-shaped groove 741, and both the left end and the right end of the rectangular block 74 are provided with a second L-shaped groove 742. The inner surfaces of the first L-shaped groove 741 and the second L-shaped groove 742 on the same side are connected. Both lower ends of the two first telescopic rods 72 are fixedly connected with sliding rods 721. The inner surface of the sliding rod 721 is slidably connected with the inner surfaces of the first L-shaped groove 741 and the second L-shaped groove 742. Both lower parts of the inner surfaces of the two sliding rods 721 are rotatably connected with one-way rotating blocks 743. The outer surface of the push rod 73 is slidably connected with the inner surface of the bottom plate 36. The front end of the push rod 73 is fixedly connected with the middle part of the rear end of the first push plate 53.

[0063] The included angle between the two parts of the above-mentioned first L-shaped groove 741 is an obtuse angle, and the included angle between the two parts of the second L-shaped groove 742 is a right angle.

[0064] Further, when the goods are transported to the destination, the bottom plate 36 is placed on the ground. At this time, the first telescopic rod 72 is compressed to the shortest, and at the same time, the sliding rod 721 is located at the lower part of the inner surface of the inclined part of the first L-shaped groove 741. Then, the upper end of the baffle 4 is pulled upward. At this time, the two rectangular plates 41 slide upward along the inner surface of the sliding groove 34. When the upper end of the baffle 4 is pulled upward, the baffle 4 drives the two U-shaped rods 71 at the upper end to move upward, and further stretches the first telescopic rod 72 upward;

[0065] Further, refer to Figure 13 Figure 13 , when the baffle 4 is pulled upward until the lower end of the triangular plate 42 is flush with the horizontal part of the inner surface of the triangular groove 821, at this time, the first telescopic rod 72 is stretched to the longest. Then, continue to pull the baffle 4 upward. Through the U-shaped rod 71, the first telescopic rod 72 and the sliding rod 721 are driven upward. Through the one-way cooperation of the one-way rotating block 743, the sliding rod 721 slides along the inner surface of the inclined part of the first L-shaped groove 741. Further, through the joint cooperation of the sliding rods 721 on both sides and the first L-shaped groove 741, the rectangular block 74 slides forward, and then the push rod 73 is pushed forward for a certain distance. Then, during the forward movement of the push rod 73, the first push plate 53 is pushed, and at the same time, several second springs 54 are stretched. During the pushing process of the first push plate 53, the goods inside the box body 3 are simultaneously pushed forward, and the goods are pushed out forward for a certain distance, which is convenient for the user to quickly unload the goods. When the sliding rod 721 slides along the inner surface of the inclined part of the first L-shaped groove 741 to the inner surface of the vertical part of the first L-shaped groove 741, the rectangular block 74 is no longer driven to move. Then, the push rod 73 and the first push plate 53 both stop moving. At this time, the front end of the goods is located in front of the front end of the box body 3, which is convenient for people to unload the goods.

[0066] Then, the first telescopic rod 72 continues to drive the sliding rod 721 upward along the inner surface of the vertical part of the first L-shaped groove 741 to the highest position. At this time, the cross plate 81 is located above the first push plate 53.

[0067] When it is necessary to transport goods through the device again, the operator presses the first push plate 53 backward, thereby simultaneously pushing the push rod 73 and the rectangular block 74 backward. At this time, the sliding rod 721 slides forward along the inner surface of the horizontal part of the second L-shaped groove 742. When the first push plate 53 is pushed until the front end of the first push plate 53 is flush with the rear side wall of the inner surface of the box body 3, at this time, the first push plate 53 no longer blocks the falling of the cross plate 81. Immediately, the cross plate 81 slides down along the outer surface of the rectangular guide rail 32 to a position where the lower end of the rectangular guide rail 32 is flush with the lower end of the cross plate 81;

[0068] During the sliding process of the cross plate 81, the second telescopic rod 83 is compressed through the cooperation of the first inclined groove 812, thereby causing the two clamping blocks 82 to move toward each other along the guide rod 33. When the cross plate 81 slides down and resets, immediately release the upper end of the baffle 4. At this time, the upper end of the baffle 4 drives the U-shaped rod 71 and the first telescopic rod 72 to slide downward until the triangular plates 42 on both sides are in close contact with the inner surface of the triangular groove 821. Immediately, the clamping blocks 82 on both sides cooperate with the triangular plates 42 in the triangular groove 821 to fix the height of the baffle 4, which is convenient for the user to load goods. At this time, the sliding rod 721 descends to a certain position along the vertical part of the second L-shaped groove 742;

[0069] Furthermore, by opening the air outlet valve 611, the gas inside the limiting pipe 61 is released, and the limiting pipe 61 returns to the compressed state. After the cross plate 81 resets, it squeezes the first push plate 53 and several second springs 54 backward, and then goods can be continuously placed on the inner surface of the box body 3 for transportation preparation.

[0070] Therefore, in this solution, when the triangular plate 42 of the baffle 4 is separated from the triangular groove 821 of the clamping block 82, the whole baffle 4 falls, realizing the automatic sealing of the box body 3 to prevent the goods from falling or being damaged during flight. Secondly, when the baffle 4 is pulled upward, through the cooperation with the rectangular block 74 and the push rod 73, the push rod 73 will push the first push plate 53, pushing the whole goods forward by a certain distance, so that the front end of the goods is located in front of the front end of the box body 3, which is convenient for the personnel to unload the goods. The whole loading device can effectively load, transport, seal and protect the goods, and can make full use of the suspension and transportation ability of the drone 1 to ensure the safety and stability of the goods during transportation, improving the practicability and efficiency of the drone transporting goods.
