Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to precise control of unmanned aerial vehicle material delivery tasks, and specifically to a unmanned aerial vehicle material delivery device and a flexible guiding mechanism design thereof. Background Art

[0002] With the continuous development of drone technology, the application of drones in logistics distribution, precision agriculture, environmental monitoring and other fields has gradually increased. Especially in the task of object delivery, drones have become an ideal choice for performing precision delivery tasks due to their high efficiency and flexibility. However, the existing drone delivery system has certain challenges in delivery accuracy, control stability and sequential delivery of objects. Especially in the process of sequential delivery and precise guidance of multiple objects, traditional mechanical structures and control systems often cannot meet the requirements of high precision and high efficiency.

[0003] In order to improve the accuracy and efficiency of drone object delivery, researchers and engineers have gradually begun to explore more sophisticated and intelligent delivery systems, especially in the design of delivery mechanisms and the control of guidance systems. In the prior art, although there are some delivery devices based on spiral guide grooves, gear drives and other structures, most designs still fail to effectively solve the problems of precise control during delivery, object sequence management and stability during flight. Therefore, there is an urgent need for an innovative drone delivery device that can achieve precise control, sequential delivery of multiple objects, reduce the impact of falling objects, and optimize the weight of the system to meet the needs of modern applications. Summary of the invention

[0004] The present invention relates to a UAV material delivery device based on a flexible guide mechanism and its flexible guide mechanism, aiming to improve the accuracy, stability and efficiency of the UAV when performing material delivery tasks. The device solves the problems of unstable delivery, material damage and difficulty in sequential delivery existing in the existing delivery devices through innovative mechanical design and precision control system, and can efficiently and accurately complete multi-material delivery tasks in complex environments.

[0005] The delivery mechanism of the present invention adopts the design of a spiral guide groove and fixes it to the fuselage of the drone. The spiral guide groove has a unique geometric structure, which enables the materials to move sequentially along the spiral trajectory during the delivery process, avoiding delivery obstacles caused by material accumulation or jamming. This design not only ensures the smooth and stable delivery of materials, but also effectively controls the timing of delivery, so that multiple materials can be released in sequence according to a predetermined order. In addition, the driving method of the delivery mechanism adopts a structure in which a large gear plate is connected to the top cover, and the top cover is connected to the conveying device through a slot, and the sequential delivery of materials is achieved by virtue of the stability of the slot structure. The design of the conveying device combines a rubber belt or similar elastic material, so that the conveying device can always fit closely to the inner wall of the spiral guide groove and maintain stable contact, ensuring the precise positioning of the material in each delivery.

[0006] The flexible guiding mechanism of the present invention mainly realizes the precise guidance of materials through flexible materials. The flexible guiding material has high elasticity and can effectively slow down the speed of the material during its falling process, thereby reducing the impact force that may be caused when the material contacts the ground. This design significantly improves the delivery accuracy of materials and reduces the risk of material damage, and is particularly suitable for mission scenarios that require high-precision delivery. The flexible guiding material is not only elastic, but also has the advantages of being light and compact, which can minimize the overall weight of the delivery system and will not significantly increase the load of the drone. Its compact design also effectively optimizes the spatial layout of the system and improves the flight efficiency and maneuverability of the drone, thereby ensuring the good performance of the system in various complex environments.

[0007] In order to ensure the accuracy and stability of the material delivery process, the present invention adopts a stepper motor as the main driving component. The stepper motor can accurately control the action of the delivery mechanism and the flexible guiding mechanism to ensure that the order and timing of material delivery meet the task requirements. The precise control of the stepper motor enables the materials to be delivered in the set order, position and speed, while avoiding delivery errors caused by equipment loss of control. In addition, the stepper motor is not only used to control the timing of material delivery, but also to adjust the retraction and extension of the flexible guiding mechanism according to the needs of the actual delivery task. Through the precise adjustment of the stepper motor, the flexible guiding mechanism can be expanded or contracted at different stages, thereby ensuring the smooth progress of the delivery process, avoiding collision or interference with other objects, and improving safety during flight.

[0012] The following is a detailed description of a UAV material delivery device based on a flexible guide mechanism of the present invention in conjunction with the accompanying drawings.

[0013] like Figure 2 As shown, the delivery device designed by the present invention includes a material storage module, which is a multi-layer spiral storage disk 1, which is circular in shape as a whole, and multiple material storage units (such as cylindrical silos 2) are evenly distributed on the disk. At the end of the spiral channel 3, a material outlet 4 is provided. The design of the spiral structure allows the material to be gradually transported inward from the outside along the spiral path. This design maximizes the utilization of the storage space, is suitable for storing a variety of small materials, and can be delivered one by one as needed. When the material is transported to the central area, the material will be accurately released by gravity.

[0014] The delivery device designed by the present invention includes a material delivery module, such as Figure 3 As shown, it includes a stepper motor 5, a gear 6, a rotating disk 7, a chute 8 and a slider 9 installed on the rotating disk, and the slider can slide along the radius of the rotating disk. The edge of the rotating disk 7 has a circle of gear teeth, which forms a gear match with the gear 6 next to it. The rotating disk is driven to rotate by a stepper motor, thereby driving the slider to spiral forward. The sliding of the slider 9 is achieved through the chute 8 set on the rotating disk. With the rotation of the rotating disk 7 and the limiting effect of the spiral channel 3, the slider will push the material inward along the spiral channel in the form of a spiral. The speed of the rotating disk can be controlled by a stepper motor to ensure that the material will not get stuck or misoperated during the transportation process.

[0015] The delivery device designed by the present invention comprises a flexible guide module, such as Figure 4 As shown, the guide module is composed of a descending cylinder 10, a stepper motor 11 and a reel 12. The descending cylinder is installed at the lower end of the delivery port. The device is made of highly elastic fabric and has a cylindrical structure. When the material is released from the delivery port, the material will enter the descending cylinder. Because the fabric is elastic, the material will be subject to resistance from the fabric during its fall in the cylinder, thereby slowing down the falling speed. This design can prevent the material from being damaged or inaccurately landed due to free fall during the delivery process. The length and diameter of the descending cylinder can be adjusted according to the mission requirements. When the drone is hovering at a higher position, the descending cylinder can be extended to ensure that the material slows down when approaching the ground, thereby achieving a smoother landing. After the delivery is completed, the stepper motor 11 can drive the reel 12 to roll up the fabric cylinder and restore it to its original state.

[0016] The specific working process of the delivery device designed by the present invention is as follows:

[0017] (1) Preparation before placing: Before placing the material, the descent cylinder is driven by a motor to unfold and hang down to the ground or close to the ground to provide sufficient buffer space.

[0018] (2) Material delivery: When the material is released into the slow-fall cylinder through the delivery port, due to the elasticity of the fabric, the material will be subject to friction and resistance from the fabric cylinder during the falling process, thereby slowing down the falling speed.

[0019] (3) Delivery completion: After the material has landed safely, the control system starts the motor to rewind the descent tube and restore it to its compact storage state so that the drone can continue to perform other tasks.

[0020] The elastic fabric of the descent tube can be made of durable and tear-resistant materials to ensure safety and stability in long-term use. In addition, the control of the motor and the reel can be automatically managed by the main control system of the drone, ensuring that the descent tube can be quickly retracted after each delivery mission without affecting the flight stability of the drone.

[0021] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
