Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a collision avoidance structure for an operational UAV. Background Technology

[0002] With the widespread application of multi-rotor drones in agricultural plant protection, power line inspection, and other fields, these drones typically need to fly at low altitudes in confined spaces and obstacle-filled environments such as forests, near power lines, and between buildings. They also need to carry spray booms, cameras, probes, and other operational mechanisms for precise operations. In these scenarios, the drone's propellers and the operational mechanisms beneath the fuselage are highly susceptible to collisions with objects such as branches, wires, and walls. This can not only cause the drone to become unstable and crash, but also easily damage the costly operational mechanisms, directly affecting operational effectiveness and safety. Therefore, while ensuring the drone's maneuverability and payload capacity, equipping operational drones with reliable collision avoidance and operational mechanism protection structures is of great significance.

[0003] Currently, common collision avoidance methods mainly involve adding collision protection frames or simple elastic collision protection rings to the outside of the drone, or relying on sensors such as vision and radar for obstacle avoidance. These solutions often use rigid brackets or simple spring supports, resulting in short buffer strokes and a single buffer direction upon impact, making them prone to jamming and unable to effectively convert collisions into sliding along the obstacle surface. Furthermore, the collision protection structure typically only protects the drone body and lacks coordination with operating mechanisms such as the spray boom and sensors beneath the fuselage. In addition, relying solely on electronic sensors for obstacle avoidance is susceptible to environmental factors such as light, smoke, dust, and vegetation obstruction, and the reliability of identifying targets such as branches and power lines is insufficient. Moreover, the lack of direct mechanical triggering and buffering mechanisms means that the overall protective effect still needs improvement. Utility Model Content

[0004] The main objective of this invention is to provide a collision avoidance structure for operational drones, so as to at least solve the problem that the operational mechanisms mounted on operational drones are easily damaged by obstacles.

[0005] To achieve the above objectives, this utility model provides a collision avoidance structure for an operational unmanned aerial vehicle (UAV), comprising: This utility model discloses a collision avoidance structure for a work drone, comprising: multiple support mechanisms, multiple anti-collision mechanisms, multiple rolling mechanisms, and an avoidance mechanism. The multiple support mechanisms are radially spaced along the horizontal center of the drone. The multiple anti-collision mechanisms are correspondingly positioned at the ends of the multiple support mechanisms furthest from the drone. The anti-collision mechanisms provide physical protection for the drone, while the support mechanisms fix the anti-collision mechanisms and absorb the collision momentum when they contact an obstacle. The multiple rolling mechanisms are fixed to the multiple anti-collision mechanisms to achieve rolling contact when they contact an obstacle. The avoidance mechanism is mounted on the drone and connected to the anti-collision and support mechanisms. The anti-collision mechanisms also drive the work mechanism to rotate at a preset angle to avoid an obstacle when in contact with it. The support mechanisms absorb part of the collision momentum through displacement. The avoidance mechanism is mounted on the drone and connected to one of the anti-collision mechanisms. When the anti-collision mechanism moves along the direction of the support mechanism after contacting an obstacle, the avoidance mechanism converts this movement into a driving force on the work mechanism, causing the work mechanism to rotate relative to the drone at a preset angle to avoid the obstacle, thus preventing a collision between the work mechanism and the obstacle. This invention solves the problem that the working mechanism mounted on a drone is easily damaged by obstacles. Attached Figure Description

[0008] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0009] like Figure 1 As shown, the anti-collision structure of a work drone of this utility model includes: multiple support mechanisms 20, multiple anti-collision mechanisms 30, multiple rolling mechanisms 40, and an avoidance mechanism 50. The multiple support mechanisms 20 are arranged radially at intervals along the horizontal center of the drone 10; the multiple anti-collision mechanisms 30 are correspondingly arranged at the ends of the multiple support mechanisms 20 away from the drone 10, and the anti-collision mechanisms 30 are used to provide physical protection for the drone 10. The support mechanisms 20 are used to fix the anti-collision mechanisms 30 and absorb the collision momentum when the anti-collision mechanisms 30 come into contact with obstacles; the multiple rolling mechanisms 40 are fixedly arranged on the multiple anti-collision mechanisms 30 to achieve rolling contact when the anti-collision mechanisms 30 come into contact with obstacles; the avoidance mechanism 50 is arranged on the drone 10 and connected to the anti-collision mechanisms 30 and the support mechanisms 20. The anti-collision mechanisms 30 are also used to drive the work mechanism 60 to rotate at a preset angle to avoid obstacles when in contact with them. The support mechanism 20 absorbs part of the collision momentum through displacement. The avoidance mechanism 50 is mounted on the drone 10 and connected to an anti-collision mechanism 30. When the anti-collision mechanism 30 moves along the direction of the support mechanism 20 after contacting an obstacle, the avoidance mechanism 50 converts this movement into a driving force on the working mechanism 60, causing the working mechanism 60 to rotate relative to the drone 10 at a preset angle to avoid the obstacle, thus preventing the working mechanism 60 from colliding with the obstacle. This invention solves the problem that the working mechanism 60 mounted on the drone is easily damaged by obstacles.

[0010] Furthermore, such as Figure 1As shown, the support mechanism 20 includes: a fixed base 21, a guide sleeve 23, a radial slide bar 22, and a buffer spring. The fixed base 21 is fixedly mounted on the UAV 10; the guide sleeve 23 extends radially along the horizontal center of the UAV 10 and is fixedly mounted on the fixed base 21; the radial slide bar 22 is axially movable and passes through the guide sleeve 23 and is detachably connected to the anti-collision mechanism 30 to guide the anti-collision mechanism 30 to move axially along the guide sleeve 23 when it collides with an obstacle; the buffer spring passes through the guide sleeve 23 to absorb the collision momentum when the anti-collision mechanism 30 contacts the obstacle. The radial slide bar 22 is axially movable and passes through the guide sleeve 23, with one end extending out of the guide sleeve 23 and detachably connected to the corresponding anti-collision mechanism 30, and the other end located inside the guide sleeve 23. A buffer spring passes through the guide sleeve 23 and surrounds the radial slide bar 22. One end of the spring abuts against the guide sleeve 23, and the other end abuts against the radial slide bar 22. It is compressed when the anti-collision mechanism 30 is pushed towards the drone 10 to absorb the impact momentum, and pushes the radial slide bar 22 and the anti-collision mechanism 30 back to their original positions after the collision disappears. This embodiment, through the cooperation of the fixed base 21, guide sleeve 23, radial slide bar 22, and buffer spring, enables the anti-collision mechanism 30 to move smoothly in a defined direction and obtain elastic buffering during a collision, thereby reducing the impact on the drone 10 and the operating mechanism 60.

[0011] Furthermore, such as Figure 3 As shown, the support mechanism 20 also includes a sensing component 24. The sensing component 24 is disposed on the fixed base 21 and the radial slide bar 22 to detect the axial displacement of the radial slide bar 22. Specifically, a trigger block or magnet can be disposed on the radial slide bar 22, and a microswitch, Hall sensor, or photoelectric sensor can be disposed on the fixed base 21, thus forming the sensing component 24. When the anti-collision mechanism 30 moves the radial slide bar 22 towards the UAV 10 to a predetermined distance under the impact of a collision, the trigger block or magnet triggers or senses the microswitch or Hall sensor, thereby outputting a detection signal representing the displacement state of the anti-collision mechanism 30. This signal can be used by the UAV 10 control system to perform deceleration, hovering, or backward control. In this embodiment, by detecting the displacement of the radial slide bar 22 through the sensing component 24, the mechanical displacement of the anti-collision mechanism 30 can be converted into an electrical signal feedback, which is beneficial for realizing the linkage between mechanical anti-collision and flight control strategies.

[0012] Furthermore, such as Figure 4As shown, the anti-collision mechanism 30 includes an arc-shaped main beam 31 and an elastic covering strip 32. The arc-shaped main beam 31 is connected to a radial slide bar 22; the elastic covering strip 32 is disposed on the side of the arc-shaped main beam 31 near the obstacle to absorb collision momentum. One end of the arc-shaped main beam 31 is connected to the radial slide bar 22, which can be connected by a thread, allowing the arc-shaped main beam 31 to move as a whole with the axial movement of the radial slide bar 22. Multiple arc-shaped main beams 31 are arranged at intervals around the circumference of the UAV 10, forming a ring-shaped or multi-segment arc-shaped protective frame around the UAV 10. The elastic covering strip 32 is disposed on the side of the arc-shaped main beam 31 near the obstacle, preferably continuously covering the outer surface of the arc-shaped main beam 31. The material can be rubber, foam, or other elastic materials, which can absorb part of the collision momentum through deformation when the anti-collision mechanism 30 comes into contact with the obstacle, and buffer the rigid contact between the arc-shaped main beam 31 and the obstacle. In this embodiment, a circumferential protective contour is formed by an arc-shaped main beam 31, and an elastic covering strip 32 is provided on its outer side, so that the anti-collision mechanism 30 has both a large protective coverage area and flexible buffering capability.

[0013] Furthermore, such as Figure 4 As shown, the rolling mechanism 40 includes a U-shaped bracket 41, a roller shaft 42, and a roller 43. The U-shaped bracket 41 is fixedly mounted on the anti-collision mechanism 30; the roller shaft 42 passes through the U-shaped bracket 41; and the roller 43 passes through the roller shaft 42 to achieve rolling contact when the anti-collision mechanism 30 contacts an obstacle. The U-shaped bracket 41 is fixedly mounted on the anti-collision mechanism 30, for example, on the upper side of the arc-shaped main beam 31, with its opening facing the anti-collision direction. The two ends of the roller shaft 42 pass through the side walls of the U-shaped bracket 41, so that the roller shaft 42 spans the opening area of ​​the U-shaped bracket 41. The roller 43 is rotatably mounted on the roller shaft 42, and the outer circular surface of the roller 43 is preferably made of a wear-resistant and elastic material. When the anti-collision mechanism 30 approaches an obstacle, the roller 43 first contacts the surface of the obstacle, and then rolls along the surface of the obstacle as the anti-collision mechanism 30 continues to move or the UAV 10 adjusts its attitude, thereby changing the contact form from sliding friction to rolling friction. This embodiment provides a rolling mechanism 40 consisting of a U-shaped bracket 41, a roller shaft 42, and a roller 43 on the anti-collision mechanism 30, which enables the anti-collision mechanism 30 to make rolling contact with the obstacle, significantly reducing contact friction and jamming risk, and facilitating the smooth sliding of the anti-collision mechanism 30 along the surface of the obstacle.

[0014] Furthermore, such as Figure 1 and Figure 2As shown, the obstacle avoidance mechanism 50 includes a fixed component 51 and a connecting rod component 52. The fixed component 51 is used to rotatably fix the working mechanism 60 to the drone 10; the connecting rod component 52 is rotatably connected to the fixed component 51 and the support mechanism 20 so as to drive the fixed component 51 to rotate at a preset angle to avoid obstacles when the anti-collision mechanism 30 moves. The connecting rod component 52 is connected to the fixed component 51 and the support mechanism 20 by a hinge to form a motion transmission link. When the anti-collision mechanism 30 is displaced through the support mechanism 20 after contacting an obstacle, the displacement is transmitted to the connecting rod component 52 through the support mechanism 20. The connecting rod component 52 swings or displaces, thereby driving the fixed component 51 to rotate around the axis between itself and the drone 10, so that the working mechanism 60 fixed on the fixed component 51 rotates at a preset angle to avoid obstacles. The preset angle can be the angle away from the obstacle. This embodiment uses a collision avoidance mechanism 50 composed of a fixed component 51 and a connecting rod component 52 to convert the linear displacement of the anti-collision mechanism 30 into the angular displacement of the working mechanism 60. It can automatically drive the working mechanism 60 to avoid obstacles during a collision without the need for an additional drive motor.

[0015] Furthermore, such as Figure 1 and Figure 3As shown, the fixing component 51 includes: a first fixing member 511, a second fixing member 512, a working bracket 513, a rotating shaft 514, and a torsion spring. A first fixing member 511 is fixedly mounted on the bottom wall of the drone 10; a second fixing member 512 is hinged to the first fixing member 511; a working bracket 513 is fixedly connected to the second fixing member 512 for mounting the working mechanism 60; a rotating shaft 514 passes through the first fixing member 511 and the second fixing member 512 to rotatably connect the first fixing member 511 and the second fixing member 512. The rotating shaft 514 is horizontally positioned and parallel to the collision surface. The working mechanism 60 can rotate around the rotating shaft 514 to approach or move away from the obstacle. The direction of rotation is a preset direction, and the angle of rotation is a preset angle. A torsion spring passes through the rotating shaft 514. The first end of the torsion spring is fixedly connected to the first fixing member 511, and the second end of the torsion spring is fixedly connected to the second fixing member 512. The torsion spring provides auxiliary rotational torque when the second fixing member 512, the working bracket 513, and the working mechanism 60 rotate around the rotating shaft 514 in the preset direction. The first fixing member 511 is fixedly mounted on the bottom wall of the drone 10, for example, by screws or bolts. The working bracket 513 is used to mount the working mechanism 60. For example, the working mechanism 60 is fixed to the working bracket 513 by screws, clips, or clamping structures, so that the working mechanism 60 rotates as a whole with the second fixing member 512. The rotating shaft 514 passes through the first fixing member 511 and the second fixing member 512, so that the first fixing member 511 and the second fixing member 512 are hinged at the rotating shaft 514. The torsion spring is sleeved on the rotating shaft 514. The first end of the torsion spring is fixedly connected to the first fixing member 511, for example, inserted into the limiting hole or slot on the first fixing member 511, and the second end of the torsion spring is fixedly connected to the second fixing member 512, for example, overlapping the limiting block or ear plate on the second fixing member 512. The torsion spring is pre-tensioned during assembly so that when the second fixing member 512, the working bracket 513, and the working mechanism 60 rotate around the pivot 514 in a preset direction, the torsion spring is gradually released and generates elastic torque, providing auxiliary rotational torque for the rotation of the second fixing member 512, thus reducing the external force required by the working mechanism 60 during obstacle avoidance. When the anti-collision mechanism 30 is no longer affected by the obstacle, the working mechanism 60 automatically returns to its original working position under its own weight. This embodiment, by using a fixing component 51 composed of the first fixing member 511, the second fixing member 512, the working bracket 513, the pivot 514, and the torsion spring, enables the working mechanism 60 to achieve obstacle avoidance rotation around the pivot 514 under the condition that the torsion spring provides auxiliary torque, reducing the driving force requirement of the obstacle avoidance mechanism 50 on the anti-collision mechanism 30, while ensuring a smooth transition of the working mechanism 60 between the working state and the obstacle avoidance state.

[0016] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, the linkage component 52 includes a front linkage 521, a middle linkage 522, and a rear linkage 523. The first end of the front linkage 521 is hinged to the anti-collision mechanism 30; the first end of the middle linkage 522 is rotatably hinged to the support mechanism 20, and the second end of the middle linkage 522 is hinged to the front linkage 521; the first end of the rear linkage 523 is hinged to the second end of the middle linkage 522, and the second end of the rear linkage 523 is hinged to the working bracket 513. The anti-collision mechanism 30 drives the front linkage 521 to move horizontally, and the front linkage 521 drives the second end of the middle linkage 522 to rotate around the first end of the middle linkage 522. The middle linkage 522 drives the rear linkage 523 to move by rotation, further driving the working mechanism 60 to rotate around the pivot 514 for obstacle avoidance. The first end of the front linkage 521 is hinged to the anti-collision mechanism 30, preferably to the arc-shaped main beam 31 or its connecting portion on the anti-collision mechanism 30. The first end of the middle connecting rod 522 is hinged to the fixed base 21. When the anti-collision mechanism 30 moves horizontally along the direction of the support mechanism 20 after contacting an obstacle, it first drives the front connecting rod 521 to move. The front connecting rod 521 drives the second end of the middle connecting rod 522 to rotate around the first end of the middle connecting rod 522. The rotation of the middle connecting rod 522 further drives the rear connecting rod 523 to move. The rear connecting rod 523 applies a thrust through its hinge point with the working bracket 513, thereby driving the working mechanism 60 to rotate around the pivot 514 to avoid obstacles. This embodiment effectively amplifies and converts the horizontal movement of the anti-collision mechanism 30 into the avoidance rotation of the working mechanism 60 through a multi-bar linkage mechanism composed of the front connecting rod 521, the middle connecting rod 522, and the rear connecting rod 523. It can achieve stable and reliable mechanical linkage avoidance with a simple structure and without the need for electric drive.

[0017] In actual operation, when the drone 10 approaches an obstacle, the anti-collision mechanism 30 at the front first contacts the obstacle, compressing the elastic covering strip 32. Simultaneously, the roller 43 supported by the U-shaped bracket 41 in the rolling mechanism 40 rolls around the roller axis 42 on the obstacle surface, guiding the anti-collision mechanism 30 to slide along the obstacle surface. The collision force is transmitted to the support mechanism 20 through the arc-shaped main beam 31, causing the radial slide bar 22 to slide inward within the guide sleeve 23 and compress the buffer spring. Part of the collision momentum is absorbed by the buffer spring. The axial displacement of the radial slide bar 22 is detected by the sensing component 24 and provides an anti-collision signal to the control system of the drone 10. During the retraction of the radial slide bar 22, the connecting rod component 52 connected to the anti-collision mechanism 30 is pulled, and each of its connecting rods swings sequentially around the hinge point with the support mechanism 20 and the fixed component 51, converting the horizontal displacement of the anti-collision mechanism 30 into a rotational torque and acting on the fixed component 51. The fixed component 51 thereby drives the working mechanism 60 to rotate around a preset axis in a direction away from the obstacle, realizing active avoidance of the obstacle. After the collision is resolved, the buffer spring pushes the radial slide bar 22 and the anti-collision mechanism 30 to reset outward. The fixed component 51 and the working mechanism 60 simultaneously return to their original working posture under their own weight, thus completing a coordinated work process of anti-collision, avoidance and reset.

[0018] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
