Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a heavy-load transport UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, generally refer to aircraft without a pilot. They can be remotely controlled or fly autonomously. UAVs are widely used in fields such as military reconnaissance, search and rescue, agricultural monitoring, environmental protection, and film and television production. Their designs include various types, such as fixed-wing UAVs and rotary-wing UAVs, each with its unique uses and advantages.

[0003] In existing technologies, the wings are fixed during use and cannot be folded during transportation. This results in a large transport space required for the drone, making transportation inconvenient. In addition, existing technologies use a single motor to drive the propeller for flight. This method results in low propeller efficiency and insufficient power redundancy. When transporting heavy cargo, the drone is prone to flight instability and crashes. Utility Model Content

[0004] The purpose of this utility model is to provide a heavy-duty transport drone to solve the problems in the background technology where the wings are fixed and cannot be folded during transportation, resulting in a large transport space required for the drone and inconvenience in transportation. At the same time, the existing technology uses a single motor to drive the propeller for flight, but the propeller has low working efficiency and insufficient power redundancy. When encountering heavy cargo, it is easy for the drone to become unstable and crash.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heavy-load transport drone, including a body, a folding component on the outer surface of the body, and a flight component on the outer surface of the body;

[0006] The folding assembly includes multiple arms, and one side of the outer surface of each arm is fixedly connected to the body. An inner folding tube clamp is fixedly installed on the side of each arm away from the body. An inner folding support plate is fixedly installed on the side of each inner folding tube clamp away from the connecting arm. A folding support rod is fixedly installed inside each inner folding support plate. An outer folding support plate is rotatably sleeved on the outer surface of each folding support rod.

[0007] The flight assembly includes multiple extension arms, and each extension arm has an end-fixing clamp fixedly installed on one side of its outer surface. Each end-fixing clamp has a motor fixedly installed on the side away from the extension arm, and each motor output shaft has a propeller on its outer surface.

[0008] Preferably, the outer folding support plates are all fixedly installed with outer folding tube clamps on the side away from the inner folding tube clamps.

[0009] Preferably, an outer folding tube clamp is fixedly installed on the side of each of the multiple protective sleeves away from the inner folding tube clamp, and the side of each of the multiple outer folding tube clamps away from the inner folding tube clamp is fixedly connected to the extension arm.

[0010] Preferably, each of the outer folding support plates has a fixing bolt threaded inside, and the fixing bolts penetrate the outer folding support plate and are threaded inside the inner folding tube clamp.

[0011] Preferably, a base is fixedly installed on the bottom of the outer surface of the machine body.

[0012] Preferably, multiple protective sleeves are fixedly installed on the bottom of the outer surface of the base.

[0013] Preferably, a mounting plate is fixedly installed on the inner wall of the base near the middle, and a battery is fixedly installed on the top of the outer surface of the mounting plate.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model allows the fixing bolt to be rotated and removed, thereby releasing the fixing bolt from its limiting position on the protective sleeve. At this point, the extension arm can be dragged upwards, causing the extension arm to drive the outer folding support plate to flip through the outer folding pipe clamp, thus folding the motor and propeller to save transportation space and increase transportation convenience.

[0016] Secondly, this utility model uses a motor to drive a propeller to generate lift and lift the device into the air. Since the motor is installed in a coaxial and opposite direction, the propeller rotates in the same direction as the motor. This method can enable the propeller to achieve higher working efficiency and ensure flight stability. Attached Figure Description

Detailed Implementation

[0022] 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 protection scope of the present utility model.

[0023] Please see Figure 1-4 A heavy-duty transport drone includes a body 1, with a folding component on the outer surface of the body 1 and a flight component on the outer surface of the body 1.

[0024] The folding assembly includes multiple arms 2, and one side of the outer surface of each arm 2 is fixedly connected to the body 1. An inner folding tube clamp 201 is fixedly installed on the side of each arm 2 away from the body 1. An inner folding support plate 202 is fixedly installed on the side of each inner folding tube clamp 201 away from the connecting arm 2. A folding support rod 203 is fixedly installed inside each inner folding support plate 202. An outer folding support plate 204 is rotatably sleeved on the outer surface of each folding support rod 203.

[0025] The flight assembly includes multiple extension arms 3, and each extension arm 3 has an end-fixing clamp 301 fixedly installed on one side of its outer surface. Each end-fixing clamp 301 has a motor 302 fixedly installed on the side of its outer surface away from the extension arm 3, and each motor 302 has a propeller 303 installed on the outer surface of its output shaft.

[0026] With the above technical solution, when it is necessary to fold the extension arm 3, the fixing bolt 8 can be rotated and removed, so that the fixing bolt 8 releases the restriction on the protective sleeve 5. At this time, the extension arm 3 can be dragged upward, so that the extension arm 3 drives the outer folding support plate 204 to flip through the outer folding pipe clamp 6 to fold the motor 302 and propeller 303 to save transportation space and increase transportation convenience.

[0027] Through the above technical solution, the end fixing clamp 301 is fixedly connected to the motor 302, and the propeller 303 is installed on the output shaft of the motor 302. The propeller 303 is driven by the motor 302 to rotate and generate lift to lift the device into the air. Since the motor 302 is installed in a coaxial and opposite manner, the rotation direction of the propeller 303 is coaxial and opposite. This method can enable the propeller 303 to achieve higher working efficiency and ensure flight stability.

[0028] Specifically, each of the multiple outer folding support plates 204 has an outer folding pipe clamp 6 fixedly installed on the side away from the inner folding pipe clamp 201.

[0029] Through the above technical solution, the outer folding tube clamp 6 supports the extension arm 3.

[0030] Specifically, the side of each of the multiple outer folding tube clamps 6 away from the inner folding tube clamp 201 is fixedly connected to the extension arm 3.

[0031] With the above technical solution, since both the extension arm 3 and the battery 4 adopt a double-layer lightweight structure, compared with the existing solution, this solution can increase its stability, reduce the vertical vibration of the extension arm 3 and the battery 4 during operation, and reduce system resonance. The preferred number of extension arms 3 and batteries 4 is four, six or eight.

[0032] Specifically, each of the multiple outer folding support plates 204 has a threaded fixing bolt 8 inside, and the multiple fixing bolts 8 all penetrate the outer folding support plate 204 and are threaded inside the inner folding tube clamp 201.

[0033] The above technical solution uses fixing bolts 8 to fix the outer folding support plate 204 and the inner folding support plate 202 together.

[0034] Specifically, a base 9 is fixedly installed on the bottom of the outer surface of the body 1.

[0035] The base 9 supports the device through the above technical solution.

[0036] Specifically, multiple protective sleeves 5 are fixedly installed on the bottom of the outer surface of the base 9.

[0037] The above technical solution protects the bottom of the base 9 with the protective sleeve 5, preventing damage to the base 9.

[0038] Specifically, a mounting plate 7 is fixedly installed on the inner wall of the base 9 near the middle, and a battery 4 is fixedly installed on the top of the outer surface of the mounting plate 7.

[0039] Through the above technical solution, the mounting plate 7 increases the stability of the base 9 while supporting the battery 4. At the same time, the cooperation between the base 9 and the battery 4 can lower the overall center of gravity of the device, achieve better control effect, and provide energy to the device through the battery 4.

[0040] When in use, if it is necessary to fold the extension arm 3, the fixing bolt 8 can be rotated and removed, so that the fixing bolt 8 releases the restriction on the outer folding support plate 204. At this time, the extension arm 3 can be dragged upward, so that the extension arm 3 drives the outer folding support plate 204 to flip through the outer folding tube clamp 6, folding the motor 302 and propeller 303 to save transportation space and increase transportation convenience. The end fixing tube clamp 301 is fixedly connected to the motor 302. At the same time, the propeller 303 is installed on the output shaft of the motor 302. The propeller 303 is driven by the motor 302 to rotate and generate lift to lift the device into the air. Since the motor 302 is installed in a coaxial and opposite manner, the rotation direction of the propeller 303 is coaxial and opposite. This method can enable the propeller 303 to achieve higher working efficiency and ensure flight stability.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
