[0031] This embodiment provides a cargo-carrying drone with good flight stability; simple manufacturing and fixing; convenient loading and unloading of items; more suitable for convenient carrying of miniature items; and high adaptability to the items carried.
[0032] Specifically, such as Figures 1 to 3 As shown, the cargo-carrying drone includes a drone body 100, a cargo basket 200, and an adjustable clamp 300. A cargo platform 110 is located on the top back of the drone body 100, and the cargo platform 110 is detachable and fixed. The cargo basket 200 is placed on the cargo platform 110 with its opening facing upwards. The cargo basket 200 is used to load items. Specifically, when the cargo-carrying drone hovers in the air or lands at a specific location for a period of time, a robotic arm is activated to grab the items to be carried and place them in the cargo basket 200. The entire loading process takes less than 8 seconds. The adjustable clamp 300 includes two clamping plates 310, which are positioned opposite each other on the cargo platform 110. The two clamping plates 310 can move closer or further apart to clamp or release the cargo basket 200.
[0033] Based on the above design, a cargo platform 110 is provided on the top back of the drone body 100. The cargo basket 200 is placed on the cargo platform 110 with its opening facing upwards. Compared with traditional drones with externally attached items, the cargo basket 200 is located on the top back of the drone body 100, which can improve the flight stability of the cargo-carrying drone. Compared with the traditional drone bottom or internal cargo compartment design, the cargo basket 200 is located on the top back of the drone body 100, and the drone body 100 supports the cargo basket 200. This simplifies manufacturing and fixing, and the upward-facing cargo basket 200 makes loading and unloading items convenient, making it more suitable for conveniently carrying miniature items. The adjustable clamp 300 includes two clamping plates 310. The two clamping plates 310 can move closer or further apart to clamp or release the cargo basket 200, which can fix cargo baskets 200 of different sizes, making it easy to replace cargo baskets 200 of different sizes and improving the adaptability to the items carried. In addition, the cargo platform 110 can be detached and fixed to the drone body 100, which facilitates the inspection of the inside of the drone body 100 and the replacement of cargo platforms 110 of different sizes, improving the adaptability to the cargo basket 200 and further improving the adaptability to the items carried.
[0034] It should be noted that the loading platform 110 is a rectangular platform with dimensions of: length × width = (80mm - 120mm) × (70mm - 100mm). For example, the length can be 80mm, 90mm, 100mm, 110mm, or 120mm, etc.; and the width can be 70mm, 80mm, 90mm, or 100mm, etc.
[0035] The cargo platform 110 is detachably connected to the drone body 100 by screws located at the four corners of the rectangular platform.
[0036] The cargo platform 110 has a main frame made of 6061 aviation aluminum, and the surface of the cargo platform 110 is equipped with a 0.5mm anti-slip textured silicone pad.
[0037] The dimensions V of the items that can be placed in the storage basket 200 are ≤115mm×95mm×35mm. For example, V can be 110mm×95mm×35mm, 115mm×90mm×35mm, 115mm×95mm×30mm, or 100mm×90mm×30mm, etc.
[0038] The drone body 100 is equipped with multiple rotors, motors, and landing gear. The landing gear is located at the bottom of the drone body 100. Multiple rotors are evenly distributed on the outer periphery of the drone body 100. The motors correspond one-to-one with the rotors. The motors drive the rotors to rotate, thereby enabling the cargo drone to take off. The motors are powered by batteries located inside the drone body 100. The specific principle is existing technology and will not be described in detail here.
[0039] In this embodiment, the cargo-carrying drone is a quadcopter drone.
[0040] The cargo-carrying drone also includes a navigation module and a control module, both located inside the drone body 100. The navigation module provides navigation for the cargo-carrying drone's flight; the control module controls the flight of the cargo-carrying drone. The specific navigation and control principles are existing technologies and will not be detailed here.
[0041] Furthermore, the cargo-carrying drone also includes a pressure stabilizing rod assembly, which is located inside the drone body 100 and positioned between the navigation module and the control module. Through its mechanical structure, the pressure stabilizing rod assembly helps the cargo-carrying drone maintain balance during flight, reducing vibrations caused by uneven motor speeds or external airflow. It can also help adjust the tilt angle of the rotor, thereby controlling the flight attitude. Moreover, through mechanical damping, the pressure stabilizing rod assembly can absorb some vibrations, improving flight stability.
[0042] In this embodiment, the pressure stabilizing rod assembly includes two front pressure stabilizing rods and two rear pressure stabilizing rods, which are symmetrically distributed. Compared to traditional drones with externally attached items, the flight stability of this cargo-carrying drone can be improved by 27%.
[0043] Optionally, the cargo drone also includes a detection module embedded in the cargo platform 110 and located at the bottom of the cargo basket 200 to measure the weight of the items inside the cargo basket 200.
[0044] In this embodiment, the detection module includes a four-point pressure sensor.
[0045] Of course, this cargo drone has a variety of intelligent functions, such as an automatic overload alarm function (if the weight of the item is >40g, an audible and visual warning will be triggered), asymmetric loading locking (if the center of gravity of the item is offset by >5mm, takeoff will be prohibited), and emergency load dropping function (press and hold the remote control for 3 seconds to automatically release the fixation). The specific setting principles and technologies are all existing technologies, so they will not be elaborated here.
[0046] Optionally, the two clamps 310 are arranged opposite each other along the first direction. The cargo basket 200 is a rectangular basket. The first direction is the width direction of the cargo basket 200, which is also the width direction of the cargo platform 110. The rectangular shape of the cargo basket 200 facilitates clamping and fixing by the clamps 310. The direction of changing the size is set to the width direction of the cargo basket 200. The adjustable clamps 300 are set up to make full use of the empty space on both sides of the width direction of the cargo basket 200, thereby improving the space utilization of the cargo platform 110 and making the structure of the cargo drone more compact.
[0047] Furthermore, the adjustable clamp 300 also includes two elastic elements 320, each corresponding to a clamping plate 310. The two ends of each elastic element 320 along the first direction are connected to the drone body 100 and the corresponding clamping plate 310, respectively. In operation, the two clamping plates 310 are pushed away from each other along the first direction, compressing the elastic elements 320; the cargo basket 200 is placed between the two clamping plates 310 (the cargo basket 200 is removed from between the two clamping plates 310); the two clamping plates 310 are released, and the two elastic elements 320, under the action of their rebound force, push the two clamping plates 310 closer together to clamp the cargo basket 200 (the two elastic elements 320 return to their natural state). The rebound force of the elastic elements 320 drives the clamping plates 310 to clamp the cargo basket 200, making the setup and operation simple.
[0048] To further secure the cargo basket 200, each clamping plate 310 is provided with a clamping claw 311 at its top. The two clamping claws 311 are arranged facing each other and are respectively clamped on the top of the two sides of the cargo basket 200 along the first direction, pressing the cargo basket 200 onto the cargo platform 110.
[0049] The cargo platform 110 has two clearance slots 111, which correspond one-to-one with the elastic element 320. The elastic element 320 is located in the clearance slot 111 on the corresponding side. The bottom of the clamping plate 310 is located in the clearance slot 111. The two ends of the elastic element 320 abut against the inner side wall of the clearance slot 111 and the outer side wall of the clamping plate 310, respectively, so as to avoid occupying the space on the surface of the cargo platform 110 and reduce the weight of the cargo platform 110, thereby reducing the weight of the entire cargo drone.
[0050] Furthermore, the adjustable clamp 300 also includes a guide rod 330, the two ends of which are respectively connected to the two inner sidewalls of the clearance groove 111 along the first direction. The clamping plate 310 is movably inserted through the guide rod 330, which guides the sliding of the two clamping plates 310.
[0051] Furthermore, the elastic element 320 is a spring, which is sleeved on the guide rod 330. The spring connection is simple, low-cost, and effective.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
