Technical Field

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

[0002] Search and rescue drones are intelligent devices that use drone technology to conduct search and rescue (SAR) missions, mainly used for quickly locating missing persons, disaster site surveys, and material delivery.

[0003] Existing search and rescue drones cannot fold their arms when participating in rescue missions, resulting in a bulky overall structure that is inconvenient to carry and store, affecting rapid deployment and rescue efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-joint robotic arm structure for search and rescue drones.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The multi-joint robotic arm structure of the search and rescue drone includes a frame, with connecting seats fixedly installed at both ends of the left and right sides of the frame. The connecting seats have through slots, and the through slots are rotatably connected to the rotating slot on one side of the first robotic arm through a first rotating column. A second robotic arm is connected to the other side of the first robotic arm, and a fixed seat is fixedly installed on one side of the second robotic arm.

[0006] The first arm is fixedly mounted with a fixed plate, and a second rotating column is installed inside the fixed plate. The second rotating column is rotatably connected to a rotating plate on one side of the second arm.

[0007] In addition, the preferred structure is that the first arm is rotatably connected to both ends of the connecting seat via the first rotating column, and the connecting seat is provided with a limit groove.

[0008] In addition, a preferred structure is that a fixed plate is fixedly installed on one side of the first arm, and the fixed plate is rotatably connected to a rotating plate on one side of the second arm through a second rotating column.

[0009] Furthermore, in a preferred configuration, the first arm is connected to one side of an elastic rope via a first connecting groove, and the other side of the elastic rope is connected to a second connecting groove in the second arm.

[0010] The beneficial effects of this utility model are as follows: by setting a connecting seat and first and second arms, the drone arms can be folded and retracted, significantly reducing the overall structure, making it easy to carry and store, and enabling rapid deployment, thereby improving rescue efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-5 The multi-joint robotic arm structure of the search and rescue drone includes a frame 1, a connecting seat 2, a first robotic arm 3, a second robotic arm 4, and a fixed seat 5. The connecting seats 2 are fixedly installed at both ends of the left and right sides of the frame 1. A through groove is opened in the connecting seat 2, and a rotating column is rotatably connected in the through groove. Limit grooves are opened on both the upper and lower sides of the connecting seat 2, and the limit grooves pass through the rotating column. A locking screw is set at the top of the connecting seat 2, and the locking screw is connected to the locking column through the locking groove. The locking column is located at the bottom of the connecting seat 2.

[0015] The first arm 3 is rotatably connected to the rotating column in the through groove of the connecting seat 2 via a rotating groove on one side. The first arm 3 has a first connecting groove on the other side, which is fixedly connected to one side of the elastic rope. The first connecting groove has grooves on both sides, and the first limiting blocks are fixedly installed on both sides of the surface of the first arm 3. The first limiting blocks have first positioning grooves. The upper and lower ends of one side of the surface of the first arm 3 are fixedly installed with fixing plates, and the two fixing plates are rotatably connected to the second rotating column.

[0016] A second connecting groove is provided on one side of the second arm 4. The bottom end of the second connecting groove is fixedly connected to the other side of the elastic rope. Protrusions are fixedly installed on both sides of the second connecting groove. The protrusions correspond to the grooves of the first arm 3. Second limiting blocks are fixedly installed on both sides of the surface of the second arm 4. A second positioning groove is provided in the second limiting block. The second limiting block corresponds to the position of the first limiting block of the first arm 3. A limiting screw is connected to one side of the second limiting block. The limiting screw is connected to the limiting post through a fixing groove. The limiting post is located on the side of the first limiting block of the first arm 3 near the frame 1. A rotating plate is fixedly installed on one side of the surface of the second arm 4. The rotating plate is rotatably connected to the rotating post in the fixing plate of the first arm 3.

[0017] The second arm 4 is fixedly installed on the side away from the frame 1 with a fixed base 5. The top of the fixed base 5 has an installation groove, and a rotating column is set in the middle of the installation groove. The top of the rotating column is rotatably connected to the bottom of the installation column, and fan blades are fixedly installed on both sides of the upper half surface of the installation column.

[0018] In this embodiment, during storage, when the search and rescue drone finishes its rescue and is stored, because the limiting screw and the limiting post fixing groove are threadedly connected, the limiting screw is separated from the limiting post fixing groove by a knob. At this time, the second arm 4 is rotated outward. At this time, the rotating plate on one side of the surface of the second arm 4 rotates outside the second rotating post inside the fixing plate on one side of the surface of the first arm 3. At this time, the elastic rope rotates outward with the second arm 4 to prevent damage to the rotating post from causing the second arm 4 to separate from the first arm 3 during folding. At this time, the second arm 4 and the first arm 3 are folded.

[0019] Since the locking screw and the locking post are threaded together, unscrew the locking screw from the locking post's locking groove. At this time, rotate the first arm 3. The rotating groove on one side of the first arm 3 rotates outside the first rotating post in the through groove of the connecting seat 2. When the first arm 3 rotates to the appropriate position, gently screw the locking screw into the locking post's locking groove to limit the first arm 3. Because the second arm 4 is folded with the first arm 3, the fan blades on the second arm 4 side of both sides of the frame 1 will not interfere with each other. At this time, place the frame 1 in the storage box, and it can be moved to another location or prepared for the next use. In use, the operation is reversed. The first arm 3 is rotated open by the first rotating column and fixed with the limiting screw. Then, by rotating the rotating plate of the second arm 4, the rotating plate rotates outside the second rotating column. At this time, the elastic rope will generate a backward pulling force, inserting the protrusion of the second arm 4 into the groove of the first arm 3, and initially limiting the first arm 3 and the second arm 4. Then, the limiting screw passes through the first and second positioning grooves and is threaded to the limiting column, completely limiting and fixing the first arm 3 and the second arm 4.

[0020] In this invention, by setting a connecting seat 2 and a first arm 3 and a second arm 4, the drone's arms can be folded and retracted, significantly reducing the overall size of the structure, making it easier to carry and store, and enabling rapid deployment, thereby improving rescue efficiency.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
