Description

Technical Field

[0001] The present invention relates to the technical field of drones, and particularly to a quick-release structure for the upper arm of a drone. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "drone", with the English abbreviation "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an on-vehicle computer. Compared with a piloted aircraft, drones are often more suitable for tasks that are too "stupid, dirty or dangerous".

[0003] For example, the publication (announcement) number: CN109592024B discloses an intelligent drone, which is based on the Internet of Things and has a remote control communication function, including a body, a flight mechanism arranged above the body, a solar power generation device, and a buffer mechanism arranged below the body. A plurality of indicator lights are arranged on the body. The intelligent drone based on the Internet of Things drives a sliding plate to move through a sliding mechanism, so that the second through hole on the sliding plate is misaligned with the first through hole on the clamping plate, thereby changing the air resistance of each balance unit and adjusting the drone to land smoothly and safely. In the ultrasonic transmitting circuit, conventional discrete components are used to reduce the production cost of the circuit while realizing wireless signal transmission.

[0004] Although the above comparative case solves the corresponding technical problems, the above comparative case still has the following defects:

[0005] The drones of the above technical solutions are equipped with corresponding functional devices, resulting in an increase in the structural volume of some models. Especially for multi-rotor drones, the number and length of the arms will increase accordingly, making it difficult to store and transport the fuselage. Summary of the Invention

[0006] The purpose of the present invention is to provide a quick-release structure for the upper arm of a drone, making the arm in a quick-release form. When flight is required, the arm is installed on the drone, and when flight is not required, the arm is removed to reduce the volume of the drone and facilitate transportation and storage.

[0007] To achieve the above purpose, the main technical solutions adopted by the present invention include:

[0008] A quick-release structure for the upper arm of a drone, comprising:

[0009] A drone fuselage, and a plurality of fuselage end arm seats arranged at equal distances are fixedly connected to the edge of the drone fuselage;

[0010] A plurality of arm mechanisms, the arm mechanisms corresponding to the fuselage end arm seats one by one. The arm mechanism includes an arm carbon tube that matches the fuselage end arm seat. A motor is installed at the end of the arm carbon tube, and a propeller is installed on the output shaft of the motor.

[0011] A quick-release mechanism for connecting the drone fuselage and the arm mechanism. The quick-release mechanism includes a first connection component installed on the fuselage end arm seat and a second connection component installed on the arm carbon tube. The first connection component and the second connection component are connected by a clamping component.

[0012] A support mechanism for supporting the drone fuselage.

[0013] In the above quick-release structure of the upper arm of the drone, the first connection component includes a fixed seat. The fixed seat is fixedly connected to the fuselage end arm seat through a first bonding part, and a spring pin is arranged inside the first bonding part.

[0014] In the above quick-release structure of the upper arm of the drone, the second connection component includes a fixing piece. The fixing piece is fixedly connected to the end of the arm carbon tube through a second bonding part, and a connector matching the spring pin is arranged inside the fixing piece.

[0015] In the above quick-release structure of the upper arm of the drone, the clamping component includes a clamping seat. A first connection seat is fixedly connected to one side of the clamping seat, and a pressing block is rotatably installed on the first connection seat through a connecting shaft. A second connection seat is fixedly connected to the other side of the clamping seat, and a connecting block is rotatably installed on the second connection seat through a connecting shaft. A handle matching the pressing block is fixedly connected to the connecting block.

[0016] In the above quick-release structure of the upper arm of the drone, an anti-slip pad is arranged on the inner wall of the pressing block, and the handle is designed in an arc shape.

[0017] In the above quick-release structure of the upper arm of the drone, the support mechanism includes support legs fixedly connected to the bottom of the drone fuselage, and a stabilizing strut is fixedly connected to the bottom of the support legs.

[0018] In the above quick-release structure of the upper arm of the drone, the handle is designed in an arc shape, and a limiting ring for limiting the fixing piece is also fixedly connected to the fixing piece.

[0019] In the above quick-release structure of the upper arm of the drone, a guiding and limiting groove is fixedly connected to the fixing piece, and a guiding and limiting pin matching the guiding and limiting groove is fixedly connected to the clamping seat at a position corresponding to the guiding and limiting groove.

[0020] In the above quick-release structure of the upper arm of the drone, a anti-detachment limit groove is further provided on the fixing member, and an anti-detachment limit rib matching the anti-detachment limit groove is fixedly connected to the pressing block at a position corresponding to the anti-detachment limit groove.

[0021] The present invention has at least the following beneficial effects:

[0022] 1. In the present invention, a quick-release structure of the upper arm of the drone is realized, which is convenient to operate, can be quickly installed and removed, and is firmly installed and reliable, and can effectively prevent the arm from falling off by itself during flight.

[0023] 2. In the present invention, the power cord connection between the arm mechanism and the drone fuselage is cancelled, and a spring pin connection is adopted. Even if there is a machining error between the arm mechanism and the drone fuselage, the elasticity of the spring pin is utilized, which does not affect the assembly. Moreover, with the spring pin connection, the power cord connection is cancelled, and the arm can be completely removed. Therefore, it is more convenient in operation, transportation and storage, and also saves more space.

[0024] 3. In the present invention, by providing a guiding limit groove and a guiding limit pin, during installation, the guiding limit groove and the guiding limit pin cooperate first, and then the spring pin contacts, which can ensure that during installation, there is no dislocation, and the spring pin will not be deformed due to dislocation, and can ensure smooth and reliable assembly.

[0025] 4. In the present invention, by providing an anti-detachment limit groove and an anti-detachment limit rib, when the handle locks the pressing block, the anti-detachment limit rib presses on the anti-detachment limit groove, which can prevent the arm assembly from falling off outward in various situations and ensure firm and reliable installation.
