Description

Technical Field

[0001] The present invention belongs to the field of unmanned aerial vehicles, relates to unmanned aerial vehicles and transportation, and in particular to a cargo compartment mounting mechanism of a logistics unmanned aerial vehicle. Background Art

[0002] In recent years, the use of unmanned equipment to transport goods has been a hot research topic, and small-scale applications have been achieved, such as unmanned express delivery vehicles and unmanned taxis. In the field of unmanned aerial vehicles, the hot research direction is to use drones to deliver express and take-out. However, there is a defect in the current drone transportation of goods, that is, it can only carry one express box / take-out box at a time, and the transportation efficiency is too low. Take taxi drivers as an example. When accepting travel orders, taxi drivers will accept orders along the way / near destinations to improve efficiency. Therefore, if the rated carrying weight of the drone is sufficient, a new drone transportation mechanism that can conveniently mount multiple express boxes / take-out boxes / cargo compartments is urgently needed. Summary of the invention

[0003] In view of the problem that it is inconvenient to mount multiple cargo holds on the above-mentioned UAV, the present invention proposes a novel UAV cargo hold mounting mechanism.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: the cargo hold mounting mechanism of the logistics drone includes a U-shaped frame, and driving modules are respectively connected to both sides of the U-shaped frame, and the driving module includes a spur gear, and the spur gear is meshed with a rack. A shelf is arranged between the two driving modules, and the side of the shelf is connected to the rack, and the rack is vertically arranged, and one side of the shelf is arranged to be open.

[0005] Preferably, the driving module comprises a bracket, the bracket is rotatably connected to a worm, one end of the worm is connected to a servo motor, the worm is meshed with a worm wheel, and the worm wheel is coaxially connected to the spur gear.

[0006] Preferably, the worm gear and spur gear are coaxially connected to rollers, the side of the shelf is connected to a track, and the track is engaged with the rollers.

[0007] Preferably, a plurality of guide rails are sequentially arranged on the two inner side walls of the shelf from top to bottom, and the guide rails are slidably connected to the cargo compartment.

[0008] Preferably, the side wall of the shelf away from the opening is provided with a plurality of vertical grooves, the side wall of the cargo hold close to the vertical grooves is threadedly connected with bolts, and one end of the bolt away from the cargo hold passes through the vertical grooves.

[0009] Preferably, a baffle is provided on the side of the vertical slot away from the cargo hold, and one end of the bolt away from the cargo hold passes through the baffle.

[0010] Preferably, a base is connected to the bottom of the shelf.

[0011] Preferably, the side of the shelf is provided with a hollow-out structure.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0013] In the present invention, the shelf is arranged in the middle of the U-shaped frame, and the cargo compartments are vertically arranged in the shelf. Therefore, when adding or removing the mounted cargo compartments, the center of gravity can always be kept near the vertical central axis, avoiding the center of gravity deviation that makes it difficult for the UAV to maintain balance during flight.

[0014] The driving module of the present invention drives the U-shaped frame and the battery to move up and down, changing the overall center of gravity height of the UAV. When the number of cargo compartments mounted in the shelf is small, the U-shaped frame descends to lower the center of gravity, which is more conducive to stable landing. When the number of cargo compartments mounted in the shelf is large, the U-shaped frame ascends to make the center of gravity below the U-shaped frame, facilitating the takeoff of the UAV and the adjustment of its attitude during flight.

[0015] In the present invention, vertical grooves are provided on the side wall of the shelf, and bolts pass through the vertical grooves and press the baffle against the side wall of the shelf, so that the cargo compartment can be fixed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To better understand the above objects, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] As Figure 1 、 Figure 2 、 Figure 3 shown, in order to facilitate the mounting of multiple cargo holds 5, the present invention provides a cargo hold mounting mechanism for a logistics drone, including a U-shaped frame 1. A propeller support rod is connected to the U-shaped frame 1, and batteries 2 are provided on both sides of the U-shaped frame 1 to achieve balance. Driving modules 3 are respectively connected to both sides of the U-shaped frame 1. The driving module 3 includes a spur gear 31, and the spur gear 31 meshes with a rack 32. A shelf 4 is provided between the two driving modules 3. The side of the shelf 4 is connected to the rack 32, and the rack 32 is vertically arranged. One side of the shelf 4 is open. The driving module 3 drives the gear to make the U-shaped frame 1 rise and fall along the shelf 4.

[0024] Specifically, the usage method of the present invention: After the drone lands on the ground, put the goods into the shelf 4. Since the overall center of gravity of the drone changes after the goods are put in, the driving module 3 is controlled by a person to start according to the volume and weight of the goods put in, so that the U-shaped frame 1 rises and falls, making it convenient for the drone to take off and land after adjusting the center of gravity.

[0025] Furthermore, the driving module 3 includes a bracket 33. A worm 34 is rotatably connected to the bracket 33. One end of the worm 34 is connected to a servo motor 35. The worm 34 meshes with a worm gear 36. The worm gear 36 is coaxially connected to the spur gear 31. Since the worm gear 36 cannot drive the worm 34 to rotate, automatic locking can be achieved after adjusting the position of the U-shaped frame.

[0026] Furthermore, the worm gear 36 and the spur gear 31 are also coaxially connected with a roller 37. A track 38 is connected to the side of the shelf 4, and the track 38 is engaged with the roller 37. The track 38 is vertically arranged, so that the spur gear 31 will not disengage from the rack 32 in the horizontal direction.

[0027] Furthermore, the side of the shelf 4 is provided with a hollow structure.

[0028] Furthermore, a plurality of guide rails 41 are sequentially arranged on the inner side walls of the two sides of the shelf 4 from top to bottom, and the guide rails 41 are slidably connected to the cargo hold 5.

[0029] Further, a plurality of vertical grooves 42 are provided on the side wall of the shelf 4 away from the open end, and a bolt 7 is threadedly connected to the side wall of the cargo hold 5 close to the vertical groove 42. One end of the bolt 7 away from the cargo hold 5 passes through the vertical groove 42.

[0030] Further, a baffle 6 is provided on the side of the vertical groove 42 away from the cargo hold 5, and one end of the bolt 7 away from the cargo hold 5 passes through the baffle 6. Specifically, since the baffle 6 is longer than the width of the vertical groove 42, by tightening the bolt 7 so that it presses on the baffle 6, the cargo hold 5 is fixed.

[0031] Further, a base 8 is connected to the bottom of the shelf 4.

[0032] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
