Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a magnetic fast-release UAV arm connection structure. Background Technology

[0002] Unmanned aerial vehicles (UAVs), or drones for short, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. UAVs are divided into civilian and military applications. In the civilian sector, the combination of drones and industry applications represents a true necessity. Currently, applications in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romantic moments have greatly expanded the uses of drones. Developed countries are also actively expanding industry applications and developing drone technology. However, in existing technologies, the drone arms and drone bodies are fixedly connected, making quick disassembly and reassembly after damage inconvenient. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a magnetic quick-release drone arm connection structure, comprising a drone body, a disassembly arm, and a drone arm. The drone body is fixedly connected to one end of the drone arm, and the other end of the drone arm is detachably connected to the disassembly arm. A propeller is rotatably connected to the end of the disassembly arm away from the drone arm. A pin slot is provided on all four sides of one end of the disassembly arm. A pin block is provided on the drone arm, and the pin block is inserted into the pin slot. A first magnetic block is fixedly connected to the end of the pin block, and a second magnetic block is provided on the inner wall of the pin slot. The first magnetic block and the second magnetic block are magnetically connected.

[0004] Optionally, a pin is fixedly connected to the middle of one end of the disassembly arm near the machine arm, and a pin hole is opened in the middle of the machine arm, and the pin and the pin hole are plugged into each other.

[0005] Optionally, it also includes a locking component, which has a first fixing rod and a first connecting hole on one side of the middle part of the arm, wherein the first fixing rod and the first connecting hole are plugged into each other.

[0006] Optionally, a first magnet is fixed to the end of the first fixing rod, and a second magnet is provided on the inner wall of the first connecting hole, and the first magnet and the second magnet are magnetically connected.

[0007] Optionally, the pin hole and the first connecting hole are connected, and a second connecting hole is provided on one side of the middle part of the pin post, and the first fixing rod and the second connecting hole are plugged into each other.

[0008] Optionally, the locking element further includes a connecting plate, and the end of the first fixing rod away from the first connecting hole is fixedly connected to the connecting plate.

[0009] Optionally, a second fixing rod is provided on the connecting plate, and a third connecting hole is provided on the side wall of the arm, wherein the second fixing rod and the third connecting hole are plugged into each other.

[0010] Optionally, the second fixing rod is provided with a mounting groove, in which a silicone ring is fixedly installed, and the wall of the third connecting hole is provided with a connecting groove, in which the silicone ring is adapted to connect.

[0011] Optionally, a protective frame is fixedly connected to the end of the disassembly arm, and the protective frame is sleeved on the outside of the propeller.

[0012] Optionally, the bottom of the unmanned aerial vehicle is fixedly connected with a support foot.

[0013] Compared to existing technologies, this invention first connects the disassembly arm and the machine arm by insertion. Then, a pin is inserted into the internal pin hole of the machine arm. After insertion, the first and second magnetic blocks attract each other magnetically, providing auxiliary fixation and preventing displacement. The first fixing rod on the locking component passes through the first connecting hole on the machine arm and then through the second connecting hole on the pin, thus radially locking the pin. Simultaneously, the first magnet at the end of the first fixing rod magnetically connects with the second magnet in the second connecting hole, providing auxiliary fixation and preventing displacement. During disassembly, the connecting plate is pulled out, causing the first fixing rod to simultaneously disengage from both the first and second connecting holes, releasing the radial lock on the pin. Then, axial force is applied to the machine arm or disassembly arm to axially disengage the pin from the pin hole, achieving disassembly and separation. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] This utility model embodiment provides a magnetic fast-release drone arm connection structure, combined with... Figures 1 to 3 As shown, the device includes a drone body 1, a disassembly arm 2, and a robotic arm 3. The drone body 1 is fixedly connected to one end of the robotic arm 3, and the other end of the robotic arm 3 is detachably connected to the disassembly arm 2. A propeller 4 is rotatably connected to the end of the disassembly arm 2 away from the robotic arm 3. A pin slot 21 is provided on all four sides of one end of the disassembly arm 2. A pin block 31 is provided on the robotic arm 3. The pin block 31 is inserted into the pin slot 21. A first magnetic block 311 is fixedly connected to the end of the pin block 31. A second magnetic block (not shown) is provided on the inner wall of the pin slot 21. The first magnetic block 311 and the second magnetic block are magnetically connected.

[0021] like Figure 3 As shown, in this embodiment, the pin slots 21 are located on the upper, lower, left, and right sides of the disassembly arm 2, respectively. The number and position of the pin blocks 31 are adapted to the pin slots 21. After the pin slots 21 and the pins are quickly connected, they can be positioned at the upper limit of the disassembly arm 2 in the up, down, left, and right directions to prevent movement and make the connection more stable.

[0022] The first magnetic block 311 is fixedly connected to the end of the pin block 31, and the second magnetic block is located on the moving path of the first magnetic block. Both the first magnetic block 311 and the second magnetic block are strong magnets. The first magnetic block 311 and the pin slot 21 are magnetically attracted to each other to achieve an auxiliary fixing effect and prevent displacement.

[0023] like Figure 3 As shown, optionally, a pin 22 is fixedly connected to the middle of one end of the disassembly arm 2 near the machine arm 3, and a pin hole 32 is opened in the middle of the inside of the machine arm 3. The pin 22 and the pin hole 32 are inserted and connected to each other, thereby stabilizing the axial connection and facilitating installation and disassembly.

[0024] like Figure 3As shown, optionally, it also includes a locking member 5, which is provided with a first fixing rod 51, and a first connecting hole 33 is provided on one side of the middle part of the arm 3. The first fixing rod 51 and the first connecting hole 33 are inserted and connected to stabilize the radial connection.

[0025] like Figure 3 As shown, optionally, a first magnet is fixed to the end of the first fixing rod 51, and a second magnet is provided on the inner wall of the first connecting hole 33. The first magnet and the second magnet are magnetically connected. Both the first magnet and the second magnet are strong magnets, and they are not easy to detach after being magnetically connected. This provides good stability while facilitating installation and disassembly, and the first fixing rod 51 is not easy to detach from the first connecting hole 33 during working vibration or rotation.

[0026] like Figure 3 As shown, optionally, the pin hole 32 and the first connecting hole 33 are connected, and a second connecting hole 221 is provided on one side of the middle portion of the pin post 22. The first fixing rod 51 is inserted into and connected to the second connecting hole 221. This arrangement can lock the radial connection between the pin post 22 and the arm 3, preventing it from disengaging.

[0027] like Figure 3 As shown, optionally, the locking member 5 further includes a connecting plate 52, and the end of the first fixing rod 51 away from the first connecting hole 33 is fixedly connected to the connecting plate 52. The connecting plate 52 is used to provide a point of force for the user when inserting or removing the rod.

[0028] like Figure 3 As shown, optionally, a second fixing rod 53 protrudes from the connecting plate 52, and a third connecting hole 34 is provided on the side wall of the arm 3. The second fixing rod 53 and the third connecting hole 34 are inserted into each other. The second fixing rod 53 is used to fix the position of the connecting plate 52, prevent the connecting plate 52 from rotating, and make the structure more stable.

[0029] like Figure 3 As shown, optionally, the second fixing rod 53 is provided with a mounting groove, in which a silicone ring 531 is fixedly installed. The wall of the third connecting hole 34 is provided with a connecting groove, and the silicone ring 531 is adapted to connect with the connecting groove. The silicone ring 531 is used to provide friction, making it difficult for the second fixing rod 53 to disengage from the third connecting hole 34, thus stabilizing the structure.

[0030] like Figure 1 and 2 As shown, optionally, a protective frame 6 is fixedly connected to the end of the disassembly arm 2, and the protective frame 6 is sleeved on the outside of the propeller 4. The protective frame 6 is used to protect the propeller 4 and prevent external objects from damaging the propeller 4.

[0031] like Figure 1As shown, optionally, a support foot 7 is fixedly connected to the bottom end of the drone body 1. The support foot 7 is used to provide support when the drone lands, preventing the drone body 1 from directly contacting the ground.

[0032] Working Principle: During use, the disassembly arm 2 and the machine arm 3 are first connected by insertion. Then, the pin 22 is inserted into the internal pin hole 32 of the machine arm 3. After insertion, the first magnetic block 311 and the second magnetic block are magnetically attracted, achieving auxiliary fixing and preventing displacement. The first fixing rod 51 on the locking component passes through the first connecting hole 33 on the machine arm 3, and then through the second connecting hole 221 on the pin 22, thereby radially locking the pin 22. Simultaneously, the first magnet at the end of the first fixing rod 51 is magnetically attracted to the second magnet in the second connecting hole 221, achieving auxiliary fixing and preventing displacement. During disassembly, the connecting plate 52 is pulled out, causing the first fixing rod 51 to simultaneously disengage from the first connecting hole 33 and the second connecting hole 221, releasing the radial locking of the pin 22. Next, axial force is applied to the machine arm 3 or the disassembly arm 2, causing the pin 22 to axially disengage from the pin hole 32, achieving disassembly and separation.

[0033] Similarly, the components included in the "components," "mechanisms," and "devices" of this disclosure can also be flexibly combined. They can be modularly produced according to actual needs and assembled as an independent module; or they can be assembled separately to form a module in this device.
