Description

Technical Field

[0001] This utility model relates to the field of drone frame technology, specifically a drone frame folding and retracting mechanism. Background Technology

[0002] A drone is an aircraft that does not require a pilot to operate it from inside the aircraft, relying on remote control, autonomous control, or a combination of both to perform flight missions. Technically, a drone typically consists of an airframe, a power system, a flight control system, a communication system, and a payload. The flight control system is the core, acting as the "brain," controlling flight attitude and trajectory according to preset programs or real-time commands. The communication system is responsible for transmitting data with the ground station or control terminal, ensuring the issuance of control commands and the transmission of flight information. The payload, depending on its purpose, may include equipment such as high-definition cameras, infrared sensors, and cargo bays. The drone frame is the structural framework that constitutes the main body of the drone, like the "skeleton system" of an aircraft, primarily used to support core components such as the power system, flight control system, communication equipment, and payload. However, existing drone frames cannot be scaled, resulting in a large footprint for the drone, making it inconvenient to store and use. Utility Model Content

[0003] The purpose of this utility model is to provide a drone frame folding and unfolding mechanism to solve the problem mentioned in the background art that the drone cannot be scaled, resulting in a large footprint and inconvenience in storage and use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drone frame folding and retracting mechanism, comprising a main body, wherein a connecting rod is fixedly connected to the surface of the main body, and a shock-absorbing block is fixedly connected to the end of the connecting rod;

[0005] The main body has a support arm 1 symmetrically fixedly connected to its surface, and a sliding groove is symmetrically embedded in the surface of the support arm 1. A guide block is embedded in the sliding groove. A rotating block is installed at the end of the support arm 1, and a support arm 2 is sleeved on the surface of the rotating block. A lead screw is embedded in the inner wall surface of the support arm 2, and the other end of the lead screw passes through the end of the support arm 2 and is connected to an installation block. A propeller is connected to the surface of the installation block.

[0006] Preferably, the connecting rods are symmetrically arranged on the bottom surface of the main body, and the support arms are symmetrically arranged on the outer side of the main body.

[0007] By adopting the above technical solution, the connecting rod can buffer and support the main body.

[0008] Preferably, the rotating block and the second support arm are rotatably connected, and the rotating block is connected between the first support arm and the second support arm.

[0009] Using the above technical solution, the second support arm is rotated so that one side of the second support arm rotates on the surface of the rotating block, thereby bending the second support arm.

[0010] Preferably, the surface of the second support arm is symmetrically provided with grooves, and the grooves of the second support arm are positioned corresponding to the sliding grooves.

[0011] Using the above technical solution, support arm 2 is installed on one side of support arm 1, so that support arm 1 and support arm 2 are the same size.

[0012] Preferably, the guide block is disposed inside the groove of the second support arm, and the guide block and the second support arm are connected by sliding friction.

[0013] Using the above technical solution, the guide block is moved to the inside of the second support arm.

[0014] Preferably, the guide block and the slide groove are slidably connected, and the guide block and the support arm are slidably frictionally connected, and the surface of the guide block is provided with protrusions.

[0015] Using the above technical solution, the guide block is moved by the protrusions on the surface of the guide block, so that the guide block slides inside the groove.

[0016] Preferably, the second support arm has internal threads, and the second support arm and the lead screw are connected by threads.

[0017] Using the above technical solution, rotate the lead screw so that it rotates along the internal thread of the second support arm, at which point the lead screw drives the mounting block to rotate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the drone frame retraction and folding mechanism:

[0019] 1. It is equipped with a support arm, a mounting block and a lead screw. When it needs to be stored, rotate the second support arm to bend it. The second support arm rotates around the rotating block and folds, which greatly reduces the size of the body and makes it easy to carry and store. At the same time, rotate the lead screw so that the lead screw drives the propeller to rotate through the mounting block. This can turn the propeller to the inside and protect it.

[0020] 2. A chute and guide block are provided. When the drone is flying, the guide block moves between support arm one and support arm two, which strengthens the connection between the two and improves the stability of the drone connection. The main body of the shock-absorbing block plays a buffering and supporting role, which can buffer the drone when it lands. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a drone frame folding and retracting mechanism, including a main body 10, a connecting rod 20, a shock-absorbing block 201, a first support arm 30, a slide 301, a rotating block 302, a second support arm 303, a mounting block 304, a propeller 305, a lead screw 306, and a guide block 307.

[0031] The drone frame's folding and retracting mechanism facilitates its storage. The specific implementation method is as follows:

[0032] A connecting rod 20 is fixedly connected to the surface of the main body 10, and a shock-absorbing block 201 is fixedly connected to the end of the connecting rod 20. Support arms 1 30 are symmetrically fixedly connected to the surface of the main body 10, and a sliding groove 301 is symmetrically embedded in the surface of the support arm 1 30. A guide block 307 is embedded inside the sliding groove 301. A rotating block 302 is installed at the end of the support arm 1 30, and a support arm 2 303 is sleeved on the surface of the rotating block 302. A lead screw 306 is embedded in the inner wall surface of the support arm 2 303, and the other end of the lead screw 306 passes through the end of the support arm 2 303 and is connected to a mounting block 304. A propeller 305 is connected to the surface of the mounting block 304. The connecting rod 20 is symmetrically arranged on the bottom surface of the main body 10, and the support arms 1 30... The rotating block 302 and the second support arm 303 are symmetrically arranged on the outside of the main body 10. The rotating block 302 is rotatably connected to the first support arm 30 and the second support arm 303. The surface of the second support arm 303 is symmetrically provided with grooves, and the grooves of the second support arm 303 are correspondingly positioned with the sliding groove 301. The guide block 307 is located inside the groove of the second support arm 303, and the guide block 307 is slidably connected to the second support arm 303. The guide block 307 is slidably connected to the sliding groove 301, and the guide block 307 is slidably connected to the first support arm 30. The surface of the guide block 307 is provided with protrusions. The inside of the second support arm 303 is provided with threads, and the second support arm 303 is threadedly connected to the lead screw 306.

[0033] Move the guide block 307 so that it slides inside both the second support arm 303 and the first support arm 30. Move the guide block 307 into the second support arm 303. At this time, the guide block 307 slides outward inside the groove of the second support arm 303. Move the guide block 307 from the second support arm 303 to the first support arm 30. Move the guide block 307 into the slide groove 301. At this time, the guide block 307 has completely moved from the second support arm 303 into the slide groove 301. At this time, the fixation of the guide block 307 between the second support arm 303 and the first support arm 30 disappears.

[0034] At this point, the second support arm 303 can be bent downwards, causing one end of the second support arm 303 to rotate downwards along the surface of the rotating block 302. This causes the second support arm 303 to drive the mounting block 304 to rotate, making the second support arm 303 and the mounting block 304 perpendicular to the first support arm 30. This causes the propeller 305 to rotate to the bottom of the main body 10. Then, the mounting block 304 is rotated, causing the mounting block 304 to drive the lead screw 306 to rotate. This causes the lead screw 306 to rotate along the internal thread of the second support arm 303, causing the mounting block 304 to drive the propeller 305 to rotate. This causes the propeller 305 to rotate to one side of the main body 10, allowing the propeller 305 to be rotated to the inside for protection.

[0035] like Figure 1The guide block 307 is positioned between the second support arm 303 and the first support arm 30. At this time, the guide block 307 can strengthen the connection between the second support arm 303 and the first support arm 30, and enhance the stability between them. Meanwhile, when the main body 10 descends, the bottom of the shock absorber 201 contacts the bottom surface. The shock absorber 201 is set as a flexible structure, which allows the shock absorber 201 to contract. At this time, the shock absorber 201 dampens the main body 10 and reduces the impact on the main body 10.

[0036] Working principle: When using the drone frame folding mechanism, a rotating block 302, a second support arm 303, a mounting block 304, a propeller 305, and a lead screw 306 are set up. The second support arm 303 can be stored, reducing the drone's footprint. At the same time, the lead screw 306 rotates the propeller 305 to the inside, protecting the propeller 305. The propeller 305, lead screw 306, and guide block 307 are also set up. When the drone descends, the shock-absorbing block 201 absorbs the shock, facilitating its protection. Meanwhile, the guide block 307 can enhance the stability between the second support arm 303 and the first support arm 304, increasing the drone's stability and overall practicality.

[0037] 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 of the present invention, the scope of which is defined by the appended claims and their equivalents.
