[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides a foldable drone, including a drone shell 1. Four equally spaced arms 4 are fixedly mounted on the outer side of the drone shell 1. A folding mechanism 2 is provided at one end of each arm 4. An adjustment mechanism 3 is fixedly mounted on the lower surface of the drone shell 1, and an imaging device 5 is fixedly mounted on the lower surface of the adjustment mechanism 3. The folding mechanism 2 includes a folding arm 20, one end of which is rotatably connected to the arm 4. A locking block 22 is fixedly mounted at one end of the folding arm 20. A positioning tube 28 is fixedly mounted at one end of the arm 4. The outer side of the positioning tube 28 is in contact with the inner side of the locking block 22. A positioning screw 23 is threaded into the inner side of the positioning tube 28. A sleeve 24 is fixedly mounted at the upper end of the positioning screw 23. A knob 25 is fixedly mounted on the upper surface of the sleeve 24. When… When the drone needs to be folded, the user can first rotate the knob 25 to rotate the positioning screw 23 counterclockwise inside the positioning tube 28, so that the positioning screw 23 gradually unscrews out. At the same time, the sleeve 24 moves upward, and the contact between the slot 27 and the upper end of the positioning tube 28 and the locking block 22 is released. At this time, the user can push the folding arm 20 to rotate around the rotating connection with the drone arm 4 to fold and store the drone arm 4. When the drone needs to be unfolded, the folding arm 20 is rotated back to its original position, so that the outer side of the positioning tube 28 and the inner side of the locking block 22 are contacted again. Then, the knob 25 is rotated clockwise to rotate the positioning screw 23 downward inside the positioning tube 28. The sleeve 24 descends accordingly until the inner side of the slot 27 is tightly contacted with the upper end of the positioning tube 28 and the locking block 22, thus completing the unfolding and fixing of the drone arm 4.

[0018] The adjustment mechanism 3 includes an adjustment frame 30. The upper surface of the adjustment frame 30 is fixedly connected to the lower surface of the drone shell 1. A rotating rod 32 is fixedly mounted on the inner walls of both sides of the adjustment frame 30. A rotating frame 36 is rotatably sleeved on the outer side of the rotating rod 32. The lower surface of the rotating frame 36 is fixedly connected to the upper surface of the imaging device 5. An adjustment rod 35 is slidably inserted into one side of the rotating frame 36. Arc grooves 38 are provided on both sides of the adjustment frame 30. The inner side of the arc grooves 38 slides against one end of the adjustment rod 35. Both ends of the adjustment rod 35 are threaded with fastening nuts 33. When it is necessary to adjust the shooting angle of the imaging device 5... First, the user loosens the fastening nuts 33 at both ends of the adjusting rod 35, allowing the adjusting rod 35 to slide against the arc grooves 38 on both sides of the adjusting frame 30. Next, the user can manually push the imaging device 5, causing the rotating frame 36 to rotate around the rotating rod 32. The adjusting rod 35 slides in the slot 34 on one side of the rotating frame 36, while both ends of the adjusting rod 35 slide in the arc grooves 38, thereby changing the pitch angle of the imaging device 5. After adjusting to a suitable shooting angle, the user tightens the fastening nuts 33 to ensure that the adjusting rod 35 fits tightly against the arc grooves 38, fixing the imaging device 5 at the current angle and completing the shooting angle adjustment.

[0019] A slot 27 is provided on the inner side of the sleeve 24. The inner side of the slot 27 fits against the upper end of the positioning tube 28 and the locking block 22. During the flight of the UAV, it can effectively prevent the folding arm 20 from loosening or shifting with the arm 4, greatly enhance the connection stability of the folding mechanism 2, ensure the stability of the UAV's flight attitude, avoid flight safety hazards caused by the shaking of the arm 4, and ensure the reliable operation of the UAV in complex flight environments.

[0020] Multiple anti-slip textures 26 are arranged in a ring on the outer side of the knob 25. The anti-slip textures 26 increase the friction between the user's hand and the knob 25. When turning the knob 25 to tighten or loosen the positioning screw 23, the user can apply force more easily and accurately. Even in wet conditions or when the hands are oily, it can effectively prevent slipping, making the operation process more convenient and efficient, and improving the user experience.

[0021] The folding arm 20 has a blade mounting port 21 at one end, which provides a dedicated mounting position for the blades, making the installation and removal of the blades simple and easy. Users can quickly replace or maintain the blades without complicated tools and operating procedures, improving the maintenance efficiency of the drone. At the same time, it also makes it easier for users to replace different types of blades according to different flight needs, enhancing the applicability of the drone.

[0022] An installation groove 31 is provided on the upper surface of the adjustment frame 30. The installation groove 31 is tightly fixed to the lower surface of the drone shell 1, making the connection between the adjustment mechanism 3 and the drone shell 1 more solid and stable. It can better withstand the various forces generated by the imaging device 5 during the angle adjustment process, avoid the shaking or damage of the imaging device 5 due to unstable connection, ensure the stability and quality of image shooting, and also improve the overall integrity and reliability of the entire drone structure.

[0023] A slot 34 is provided on one side of the rotating frame 36. The inner side of the slot 34 slides and fits against the adjusting rod 35. This fit allows the adjusting rod 35 to slide smoothly on one side of the rotating frame 36, ensuring that when adjusting the angle of the imaging device 5, the adjusting rod 35 can move accurately along the predetermined trajectory, thereby precisely controlling the pitch angle of the imaging device 5.

[0024] Among them, the imaging device 5 is prior art and will not be described in detail; at the same time, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0025] Working principle: When the drone needs to be folded, the user can first rotate the knob 25 to drive the positioning screw 23 to rotate counterclockwise inside the positioning tube 28, so that the positioning screw 23 gradually unscrews out. At the same time, the sleeve 24 moves upward, and the contact between the slot 27 and the upper end of the positioning tube 28 and the locking block 22 is released. At this time, the user can push the folding arm 20 to rotate around the rotation connection with the drone arm 4 to realize the folding and storage of the drone arm 4. When the drone needs to be unfolded, the folding arm 20 is rotated back to its original position, so that the outer side of the positioning tube 28 and the inner side of the locking block 22 are contacted again. Then, the knob 25 is rotated clockwise to drive the positioning screw 23 to rotate downward inside the positioning tube 28. The sleeve 24 descends accordingly until the inner side of the slot 27 is tightly contacted with the upper end of the positioning tube 28 and the locking block 22, thus completing the unfolding and fixing of the drone arm 4.

[0026] When it is necessary to adjust the shooting angle of the imaging device 5, the user first loosens the fastening nuts 33 at both ends of the adjusting rod 35, so that the adjusting rod 35 and the arc grooves 38 on both sides of the adjusting frame 30 are in a sliding state. Then, the user can manually push the imaging device 5, causing the rotating frame 36 to rotate around the rotating rod 32. The adjusting rod 35 slides in the slot 34 on one side of the rotating frame 36, and at the same time, the two ends of the adjusting rod 35 slide in the arc grooves 38, thereby changing the pitch angle of the imaging device 5. After adjusting to a suitable shooting angle, the user tightens the fastening nuts 33 again, so that the adjusting rod 35 and the arc grooves 38 fit tightly, fixing the imaging device 5 at the current angle, thus completing the adjustment of the shooting angle.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
