DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1, as Figure 1 and Figure 2As shown, a suspended UAV cargo carrying device includes a UAV 1, a traction rope 2 and a box body 3. The bottom of the UAV 1 is movably connected to the upper end of the traction rope 2, the upper end of the box body 3 is movably connected to the lower end of the traction rope 2, a baffle 4 is arranged on the front side of the box body 3, a lifting mechanism 6 is fixedly connected to the bottom wall of the inner surface of the box body 3, a limiting mechanism 5 is fixedly connected to the left and right side walls and the rear side wall of the inner surface of the box body 3, a sliding mechanism 7 is slidably connected to the middle part of the rear end of the box body 3, and a lifting mechanism 8 is slidably connected to the left and right side walls of the inner surface of the box body 3.

[0036] When it is necessary to use the drone 1 in conjunction with the box body 3 to carry goods, first, the goods to be transported are placed in the upper part of the jacking mechanism 6 in sequence, and at the same time, the limiting mechanism 5 set 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 where the goods are offset and damaged during transportation. After the goods fill the inner surface of the box body 3, the jacking mechanism 6 cooperates to push the goods upward as a whole. During the pushing process, the baffle 4 cooperates with the lifting mechanism 8 to automatically fall, and the box body 3 is sealed as a whole;

[0037] After sealing is completed, the box body 3 and the drone 1 are connected by the traction rope 2, and the length of the traction rope 2 can be rolled up, so that the drone 1 can drive the box body 3 for flight transportation. The traction rope 2, the drone 1 and the box body 3 are all movably connected. When the traction rope 2 is needed to connect the drone 1 and the box body 3, the two ends of the traction rope 2 are fastened and fixed to the drone 1 and the box body 3 respectively. When the drone 1 drives the box body 3 to the designated destination, the traction rope 2 is removed for easy unloading.

[0038] After the goods are delivered, the baffle 4 is pulled upwards, and through cooperation with the sliding mechanism 7 and part of the limit mechanism 5, the goods on the inner surface of the box body 3 can be pushed outward for a certain distance, making it convenient for the operator to quickly unload the goods and saving transportation time.

[0039] During the operation of this embodiment, the limiting mechanism 5 can automatically adapt to the different sizes of goods for limiting and clamping, which on the one hand ensures the stability of the goods during transportation and prevents damage caused by shaking or deviation, and on the other hand, no additional manual fixation of the goods is required. At the same time, the cooperation of the rising mechanism 8 causes the baffle 4 to fall automatically, 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 upwards can also enable the sliding mechanism 7 and part of the limiting mechanism 5 to work together to push the goods inside the box body 3 outward for a certain distance, making the process of unloading goods more convenient and saving the operator's time and energy.

[0040] Embodiment 2: Based on embodiment 1, in order to realize the effect that the baffle plate 4 automatically drops and seals the box body 3, the baffle plate 4 is also stretched to cooperate with the push rod 73 and the push plate 1 53 to push the goods out a certain distance.

[0041] See also Figure 3 , Figure 4 and Figure 6 A rectangular groove 31 is provided on the rear side wall of the inner surface of the box body 3, a circular hole 35 is provided in the middle of the rear end of the box body 3, rectangular guide rails 32 are fixedly connected to the middle of the left and right walls of the inner surface of the box body 3, guide rods 33 are fixedly connected to the front of the left and right walls of the inner surface of the box body 3, sliding grooves 34 are symmetrically provided 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 in conjunction with the box body 3 to transport goods, in the process of placing the goods on the inner surface of the box body 3, the rectangular groove 31 and the two rectangular guide rails 32 cooperate with the limiting mechanism 5 to limit and clamp the goods, and at the same time, the baffle 4 cooperates with the two slide grooves 34 to slide freely, so as to facilitate the sealing or opening of the box body 3 as a whole.

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

[0044] Specifically, when the goods are placed in the box body 3 in sequence, the goods will squeeze the limit plates 51 at the left and right ends and then compress the spring 1 52, so that the multiple springs 1 52 on both sides cooperate with the limit plates 51 to clamp and limit the goods. At the same time, during transportation, the multiple springs 1 52 cooperate with the limit plates 51 to clamp the goods to prevent the goods from tilting and being damaged.

[0045] The plurality of springs 52 mentioned above all have elastic rollers inside to limit the springs 52. When the limiting plate 51 squeezes the springs 52, the elastic rollers are compressed at the same time. At the same time, the elastic rollers on both sides cooperate with the springs 52 and the limiting plate 51 to clamp and limit the goods.

[0046] At the same time, in the process of placing goods on the inner surface of the box body 3, the lifting mechanism 8 cooperates to push the push plate 1 53 backward, thereby compressing the plurality of springs 2 54 at the same time. At this time, the front end of the push plate 1 53 is flush with the rear side wall of the inner surface of the box body 3.

[0047] See also Figure 5The lifting mechanism 6 includes a limiting tube 61 fixedly connected to the middle part of the bottom wall of the inner surface of the box body 3, a cylinder 63 is fixedly connected to the front side of the upper end of the bottom plate 36, a pipe 62 is fixedly connected to the bottom wall of the inner surface of the cylinder 63 and the bottom end of the limiting tube 61, a push plate 2 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 pipe 62 located on the bottom wall of the inner surface of the cylinder 63, and an air outlet valve 611 is fixedly connected to the front side of the upper end of the limiting tube 61.

[0048] The one-way valve 621 mentioned above 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, the goods are placed on the upper end of the limiting tube 61. When the inner surface of the box body 3 is filled with goods, the upper end of the push plate 2 64 is pushed and pulled up and down to drive the push plate 2 64 to move back and forth along the inner surface of the cylinder 63. At the same time, the one-way valve 621 is opened, so that air can only flow from the inner surface of the cylinder 63 to the inner surface of the pipe 62, but cannot flow in the opposite direction.

[0050] During the reciprocating movement of the push plate 2 64, the air is pushed toward the inner surface of the pipe 62 through the inner surface of the cylinder 63 through the reciprocating movement of the push plate 2 64, and then enters the interior of the limit tube 61, so that the upper end of the limit tube 61 moves upward, and the limit tube 61 as a whole is no longer in a compressed state;

[0051] Furthermore, when the upper end of the limiting tube 61 moves upward, it pushes the goods on the upper end of the limiting tube 61 to move upward at the same time, and at the same time, the goods slide upward along the surface of the limiting plate 51, and the limiting plates 51 on both sides continue to clamp the goods.

[0052] See also Figure 7-9 The lifting mechanism 8 includes a horizontal plate 81 slidably connected to the outer surfaces of the two rectangular guide rails 32, and the front end of the horizontal plate 81 is symmetrically slidably connected to the second telescopic rod 83, and the front ends of the two telescopic rods 83 are fixedly connected to the card block 82.

[0053] When the goods inside the box body 3 are driven by the limiting tube 61 to move upward, they contact the lower end of the cross plate 81. Then, as the goods continue to move upward, they push the cross plate 81 upward, and then the two blocks 82 move away from each other through the cooperation of the two telescopic rods 83.

[0054] See also Figure 8 The left and right ends of the horizontal plate 81 are both provided with grooves 811, and the inner surfaces of the two grooves 811 are respectively slidably connected with the adapted rectangular guide rails 32. The front end of the horizontal plate 81 is symmetrically provided with inclined grooves 812, and the upper outer surfaces of the two telescopic rods 83 are slidably connected with the inner surface of the adapted inclined grooves 812. The two blocks 82 are both provided with triangular grooves 821 on the side close to each other, and the upper parts of the two blocks 82 away from each other are respectively slidably connected with the outer surfaces of the adapted guide rods 33.

[0055] For further information, see Fig. 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 telescopic rod 2 83 is stretched through the cooperation of the inclined groove 1 812. When the telescopic rod 2 83 is stretched to the longest, the cross plate 81 continues to move upward. At this time, the telescopic rod 2 83 slides along the inner surface of the inclined groove 1 812, driving the block 82 to slide along the outer surface of the guide rod 33 toward the side where the two blocks 82 are away from each other.

[0056] See also Fig.10 A rectangular plate 41 is fixedly connected to the front sides of the left and right ends of the baffle 4, and a triangular plate 42 is fixedly connected to the lower parts of the rear sides of the left and right ends of the baffle 4. The two triangular plates 42 can fit tightly against the inner surfaces of the matching triangular grooves 821, and the outer surfaces of the two rectangular plates 41 are slidably connected to the inner surfaces of the slide grooves 34.

[0057] Furthermore, when the two blocks 82 slide until the inner surface of the triangular groove 821 is not in close contact with the lower end of the triangular plate 42, the push and pull of the second push plate 64 is stopped, that is, the upper end of the limit tube 61 is no longer moved, and the goods and the horizontal plate 81 are stationary. When the lower end of the triangular plate 42 is separated from the inner surface of the triangular groove 821, the baffle 4 falls as a whole, and the rectangular plates 41 on both sides slide downward along the inner surface of the slide groove 34, thereby sealing the box body 3 and putting the whole device in a sealed state. At the same time, the limit plates 51 on both sides of the goods and the push plate 1 53 on the rear side cooperate with each other to keep the goods in a clamped state during transportation.

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

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

[0060] See also Fig.11 and Fig.12 The sliding mechanism 7 includes a U-shaped rod 71 symmetrically fixedly connected to the upper end of the rectangular plate 41, and the rear parts of the two U-shaped rods 71 ​​close to each other are fixedly connected with a telescopic rod 72, and the two telescopic rods 72 are slidably connected with a rectangular block 74, and the front end of the rectangular block 74 is fixedly connected with a push rod 73.

[0061] Specifically, when the baffle 4 automatically falls to seal the box body 3, the baffle 4 will drive the two U-shaped rods 71 ​​to fall at the same time, and then the two U-shaped rods 71 ​​will drive the telescopic rod 1 72 to slide down along the rectangular block 74 for a while, and the telescopic rod 1 72 will be compressed until the upper end of the baffle 4 is flush with the upper end of the box body 3, and the baffle 4 will no longer move. At this time, the telescopic rod 1 72 is compressed to the shortest point.

[0062] See also Fig.12 The left and right ends of the rectangular block 74 are both provided with an L-shaped groove 1 741, and the left and right ends of the rectangular block 74 are both provided with an L-shaped groove 2 742. The inner surfaces of the L-shaped groove 1 741 and the L-shaped groove 2 742 on the same side are connected. The lower ends of the two telescopic rods 1 72 are fixedly connected with a slide bar 721. The inner surfaces of the slide bar 721 are slidably connected with the inner surfaces of the L-shaped groove 1 741 and the inner surfaces of the L-shaped groove 2 742. The lower parts of the inner surfaces of the two slide bars 721 are rotatably connected with a one-way rotating block 743. The outer surface of the push rod 73 is slidably connected with the inner surface of the bottom plate 36, and the front end of the push rod 73 is fixedly connected with the middle part of the rear end of the push plate 1 53.

[0063] The included angle between the two parts of the above-mentioned L-shaped groove 1 741 is an obtuse angle, and the included angle between the two parts of the above-mentioned middle L-shaped groove 2 742 is a right angle.

[0064] Furthermore, when the goods are transported to the destination, the bottom plate 36 is placed on the ground. At this time, the telescopic rod 72 is compressed to the shortest point, and the slide bar 721 is located at the lower part of the inner surface of the inclined part of the L-shaped groove 741, and 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 slide 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, thereby stretching the telescopic rod 72 upward.

[0065] For further information, see Fig.13 When the baffle plate 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, the telescopic rod 72 is stretched to the longest point, and then the baffle plate 4 is pulled upward, and the telescopic rod 72 and the sliding rod 721 are driven upward by the U-shaped rod 71, and the sliding rod 721 slides along the inner surface of the inclined part of the L-shaped groove 741 through the unidirectional cooperation of the one-way rotating block 743, and then the sliding rod 721 on both sides cooperates with the L-shaped groove 741 to make the rectangular block 74 slide forward, and then push the push rod 73 to move forward a distance, and then That is, the push rod 73 pushes the push plate 53 during the forward movement, and the springs 54 are stretched at the same time. During the pushing process of the push plate 53, the goods inside the box body 3 are pushed forward at the same time, and the goods are pushed forward as a whole for a certain distance, which is convenient for users to quickly unload the goods. When the slide bar 721 slides along the inner surface of the inclined part of the L-shaped groove 741 to the inner surface of the vertical part of the L-shaped groove 741, the rectangular block 74 is no longer driven to move, and then the push rod 73 and the push plate 53 stop moving. At this time, the front end of the goods is located at the front side of the front end of the box body 3, which is convenient for users to unload the goods.

[0066] Then, the telescopic rod 72 continues to drive the slide bar 721 upward to rise to the highest point along the inner surface of the vertical portion of the L-shaped groove 741. At this time, the horizontal plate 81 is located above the push plate 53.

[0067] When it is necessary to transport goods through the device again, the operator presses the push plate 1 53 backward, thereby pushing the push rod 73 and the rectangular block 74 backward at the same time. At this time, the slide bar 721 slides forward along the inner surface of the horizontal part of the L-shaped groove 2 742. When the push plate 1 53 is pushed until the front end of the push plate 1 53 is flush with the rear side wall of the inner surface of the box body 3, the push plate 1 53 no longer blocks the cross plate 81 from falling. Then the cross plate 81 slides down along the outer surface of the rectangular guide rail 32 until the lower end of the rectangular guide rail 32 is flush with the lower end of the cross plate 81.

[0068] During the sliding of the horizontal plate 81, the telescopic rod 2 83 is compressed through the cooperation of the inclined groove 1 812, so that the two clamping blocks 82 move toward each other along the guide rod 33. When the horizontal plate 81 slides down and resets, the upper end of the baffle 4 is released immediately. At this time, the upper end of the baffle 4 drives the U-shaped rod 71 and the telescopic rod 1 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. Then, the clamping blocks 82 on both sides cooperate with the matching triangular plates 42 through the triangular groove 821 to fix the height of the baffle 4, which is convenient for users to load goods. At this time, the sliding rod 721 descends to a certain position along the vertical part of the L-shaped groove 2 742;

[0069] Then, the gas inside the limiting tube 61 is released by opening the air outlet valve 611, and the limiting tube 61 returns to the compressed state. After the horizontal plate 81 is reset, it squeezes the push plate 1 53 and the plurality of springs 2 54 backwards, and then the goods can continue to be placed on the inner surface of the box body 3 for transportation.

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