Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a robotic arm for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs), or unmanned aerial vehicles, have developed into flight platforms with a certain degree of autonomous flight capability and environmental adaptability in recent years, thanks to the continuous maturation of technologies such as electronic manufacturing, navigation, and control. In my country, UAVs have rapidly entered people's lives, especially in the logistics industry, where the role of UAV delivery is becoming increasingly prominent. Utilizing the precise take-off and landing, as well as the small size and flexibility of UAVs, they can be used to transport small items over short distances with simple operation and settings.

[0003] The robotic arm installed on a drone and the rod connecting the drone are usually fixed. When grasping objects of different shapes and positions, the robotic arm is restricted and can only operate in a fixed direction. The drone needs to constantly adjust its flight attitude and position to meet the operational needs of the robotic arm, which increases the complexity of the operation. Therefore, we propose a robotic arm for drones. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm for drones. By setting a steering component, the angle of the object grasped by one end of the rotating rod can be controlled. The steerable rod allows the grasping device to operate within a wider angle range, thereby increasing the flexibility of the drone in grasping objects. This makes it easier for the drone to adapt to different grasping environments and object shapes. It solves the problem that existing robotic arms are limited when grasping objects of different shapes and placement positions, and can only operate in a fixed direction. The drone needs to constantly adjust its flight attitude and position to meet the operational needs of the robotic arm, which increases the complexity of operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a robotic arm for drones, including a rotating rod one, a rotating rod two rotatably connected to the left side of the rotating rod one, a connecting plate fixedly connected to the top of the rotating rod two, a battery fixedly connected to the top of the rotating rod one, a signal receiver fixedly connected to the side wall of the rotating rod two, and the connecting plate is provided with mounting holes. The device is installed on the drone by screws passing through the connecting plate.

[0007] The second rotating rod has a steering assembly on its side wall. The steering assembly includes a hydraulic cylinder fixedly connected to the side wall of the second rotating rod. The output end of the hydraulic cylinder is fixedly connected to a support frame. The second rotating rod has a sliding groove inside. A moving block is slidably connected to the inner wall of the sliding groove. The side of the moving block away from the first rotating rod is fixedly connected to the outer surface of the support frame. Support rods are rotatably connected to both sides of the moving block. The ends of the two support rods away from the moving block are rotatably connected to the side wall of the first rotating rod. The moving block controls the rotation angle of the first and second rotating rods through the support rods on both sides, thereby controlling the angle of the object grasped by the end of the first rotating rod. The steerable rods allow the grasping device to operate within a wider angle range, thereby increasing the flexibility of the drone in grasping objects. This makes it easier for the drone to adapt to different grasping environments and object shapes.

[0008] Furthermore, the inside of the rotating rod has a wire-passing groove, and a connecting wire is connected to the outer surface of the battery. The connecting wire passes through the inside of the wire-passing groove, and a dual-axis motor is fixedly connected to the end of the connecting wire away from the battery. The connecting wire passes through the wire-passing groove opened inside the rotating rod, thereby protecting the connecting wire from damage caused by external bumps.

[0009] Furthermore, a fixing block is fixedly connected to the end of the rotating rod one that is away from the rotating rod two. The inner wall of the fixing block is fixedly connected to the outer surface of the dual-axis motor. The dual-axis motor is model AX-, and is small in size, making it suitable for installation in application scenarios with limited space.

[0010] Furthermore, the outer surface of the fixing block is provided with a clamping assembly, which includes two gears rotatably connected to the outer surface of the round rod. The outer surfaces of the two gears rotatably connect to gears 1. The sides of the two gears 1 that are close to each other are fixedly connected to the output end of the dual-axis motor. The ends of the two gears 1 that are away from the fixing block are fixedly connected to a fixing frame. Several round rods are fixedly connected to the inner wall of the fixing frame. The fixing frames on both sides are close to each other to clamp the object. The side of the fixing frames on both sides that is close to the object is provided with a striped groove, which can increase the friction between the fixing frame and the object when gripping the object, thereby gripping the object more firmly.

[0011] Furthermore, the fixed frame is equipped with an electric push rod inside. The electric push rod is rotatably connected to the outer surface of the round rod through a connecting block. The output end of the electric push rod is rotatably connected to a clamping block through the connecting block. The inner wall of the clamping block is rotatably connected to the outer surface of the round rod located at the end of the fixed frame. The electric push rod pushes the clamping block to rotate, and the clamping blocks on both sides rotate to the surface of the object being grabbed, thereby ensuring that the object will not fall off due to vibration, airflow or other factors during the flight or operation of the drone.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting a steering component, specifically by activating a hydraulic cylinder to control the support frame to move up and down, and simultaneously controlling the moving block to slide inside the slide groove, allows the moving block to control the rotation angle of rotating rod one and rotating rod two through the support rods on both sides, thereby controlling the angle of the object grasped by the end of rotating rod one. The steerable rods allow the grasping device to operate within a wider angle range, thereby increasing the flexibility of the drone in grasping objects. This makes it easier for the drone to adapt to different grasping environments and object shapes.

[0014] 2. This utility model features a clamping assembly. Specifically, as gear one rotates, gear two rotates simultaneously. Since gear one and gear two mesh, the fixing frames on both sides approach each other to clamp the object. The fixing frames on both sides have grooved slots on the side closest to the object, which increases the friction between the fixing frames and the object when gripping it, thus making the grip more secure. When gripping small objects, after the fixing frames are fixed to the object, the electric push rod is activated to rotate the clamping blocks. The clamping blocks on both sides rotate to the surface of the object being gripped, thus ensuring that the object will not fall off due to vibration, airflow, or other factors during the flight or operation of the drone.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model is a robotic arm for drones, including a rotating rod 1, a rotating rod 2 101 rotatably connected to the left side of the rotating rod 1, a connecting plate 102 fixedly connected to the top of the rotating rod 2 101, a battery 103 fixedly connected to the top of the rotating rod 1, and a signal receiver 104 fixedly connected to the side wall of the rotating rod 2 101.

[0026] A steering assembly 2 is provided on the side wall of the second rotating rod 101. The steering assembly 2 includes a hydraulic cylinder 201 fixedly connected to the side wall of the second rotating rod 101. A support frame 202 is fixedly connected to the output end of the hydraulic cylinder 201. A sliding groove 203 is provided inside the second rotating rod 101. A moving block 204 is slidably connected to the inner wall of the sliding groove 203. The side of the moving block 204 away from the first rotating rod 1 is fixedly connected to the outer surface of the support frame 202. Support rods 205 are rotatably connected to both sides of the moving block 204. The ends of the two support rods 205 away from the moving block 204 are rotatably connected to the side wall of the first rotating rod 1. By setting the steering component 2, specifically by activating the hydraulic cylinder 201 to control the support frame 202 to move up and down, while the support frame 202 moves, the moving block 204 is controlled to slide inside the slide groove 203. The moving block 204 controls the rotation angle of the rotating rod 1 and the rotating rod 201 through the support rods 205 on both sides, thereby controlling the angle of the object grasped by the end of the rotating rod 1. The steerable rods allow the grasping device to operate in a wider range of angles, thereby increasing the flexibility of the UAV in grasping objects. This makes it easier for the UAV to adapt to different grasping environments and object shapes.

[0027] The inside of the rotating rod 1 has a wire groove 301, and the outer surface of the battery 103 is connected to a connecting wire 302. The connecting wire 302 passes through the inside of the wire groove 301, and a dual-axis motor 304 is fixedly connected to the end of the connecting wire 302 away from the battery 103.

[0028] A fixing block 303 is fixedly connected to the end of the rotating rod 1 away from the rotating rod 2 101. The inner wall of the fixing block 303 is fixedly connected to the outer surface of the dual-axis motor 304.

[0029] The outer surface of the fixing block 303 is provided with a clamping assembly 4. The clamping assembly 4 includes two gears 402 that are rotatably connected to the outer surface of the round rod 404. The outer surfaces of the two gears 402 are meshed with gears 401. The sides of the two gears 401 that are close to each other are fixedly connected to the output end of the dual-axis motor 304.

[0030] Two gears 401 are fixedly connected to a fixed frame 403 at the end away from the fixed block 303, and several round rods 404 are fixedly connected to the inner wall of the fixed frame 403.

[0031] An electric push rod 405 is installed inside the fixed frame 403. The electric push rod 405 is rotatably connected to the outer surface of the round rod 404 through a connecting block.

[0032] The output end of the electric push rod 405 is rotatably connected to a clamping block 406 via a connecting block. The inner wall of the clamping block 406 is rotatably connected to the outer surface of the round rod 404 located at the end of the fixed frame 403. By setting the clamping component 4, specifically, as the gear one 401 rotates, it simultaneously drives the gear two 402 to rotate. Since the gear one 401 and the gear two 402 are meshed, the fixed frames 403 on both sides move closer to each other to clamp the object. The side of the fixed frames 403 on both sides that is closer to the object is provided with a striped groove, which can increase the friction between the fixed frame 403 and the object when gripping the object, thereby gripping the object more firmly. When gripping small objects, after the fixed frame 403 is fixed to the object, the electric push rod 405 is then activated to push the clamping block 406 to rotate. The clamping blocks 406 on both sides rotate to the surface of the object being gripped, thereby ensuring that the object will not fall off due to vibration, airflow or other factors during the flight or operation of the drone.

[0033] A specific application of this embodiment is as follows: The device is mounted on a mounting bracket at the bottom of a drone via a connecting plate 102. The drone is then started, propelling the device in flight. When the drone reaches its destination, the operator controls the signal receiver 104 mounted on the surface of the rotating rod 101 to issue a gripping and placing command to the device. The connecting cable 302 leading to the dual-axis motor 304 passes through a wire groove 301 inside the rotating rod 1, thus protecting the connecting cable 302 from damage caused by external impacts. The dual-axis motor 304 is started, controlling the rotation of gears 401 at both ends. As gears 401 rotate, they simultaneously drive gears 401 and 402. 2. Rotation: Due to the meshing connection between gear 1 401 and gear 2 402, the fixing frames 403 on both sides approach each other to clamp the object. The fixing frames 403 on both sides are provided with striped grooves on the side closest to the object. When gripping the object, the friction between the fixing frame 403 and the object can be increased, thus gripping the object more firmly. When gripping small objects, after the fixing frame 403 is fixed to the object, the electric push rod 405 is then activated to push the clamping block 406 to rotate. The clamping blocks 406 on both sides rotate to the surface of the object being gripped, thus ensuring that the object will not fall off due to vibration, airflow or other factors during the flight or operation of the drone.

[0034] The hydraulic cylinder 201 is activated to control the support frame 202 to move up and down. While the support frame 202 is moving, the moving block 204 is controlled to slide inside the slide groove 203. The moving block 204 controls the rotation angle of the rotating rod 1 and the rotating rod 201 through the support rods 205 on both sides, thereby controlling the angle of the object grasped by the end of the rotating rod 1. The steerable rods allow the grasping device to operate in a wider range of angles, thereby increasing the flexibility of the UAV in grasping objects. This makes it easier for the UAV to adapt to different grasping environments and object shapes.
