Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a quadcopter UAV frame assembly. Background Technology

[0002] The drone frame assembly refers to the mechanical skeleton that constitutes the main structure of the drone, supporting the arms, power system, payload, and other components. Its structural design directly affects the drone's strength, weight, center of gravity distribution, and flight stability. Frame assemblies are characterized by high efficiency, modularity, and ease of expansion, facilitating functional integration and system maintenance for developers. In existing quadcopter drones, arms are typically mounted at the four corners of the frame, with rotors fixed at the ends of the arms. The four rotors propel the drone for takeoff.

[0003] However, existing quadcopter drones typically fix their arms and frame components by bolts or direct welding. While this method ensures structural stability, it does not allow for adjustment of the horizontal angle of the arms. When the operator assembles electronic equipment on the drone, the drone's center of gravity changes. Since the arms cannot be adjusted, the operator cannot change the drone's center of gravity position, increasing the difficulty of operating the drone during flight.

[0004] Therefore, those skilled in the art have provided a quadcopter drone frame assembly to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quadcopter drone frame assembly. By rotating the arm adjustment column, the horizontal angle of the arm can be adjusted. After adjustment, rotating the knob moves the positioning plate into the positioning slot via the screw, fixing the arm angle and ensuring the stability of the angle during flight.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quadcopter drone frame assembly, comprising a drone body, wherein adjustment mechanisms are provided at the front ends and middle of both sides of the drone body, and an arm is provided on one side of each of the four adjustment mechanisms;

[0007] The four adjustment mechanisms include four adjustment columns, four base posts, four adjustment rings, and four screws. The four adjustment columns are movably mounted on the four base posts. Limiting grooves are formed on both sides of the inner wall of each of the four adjustment rings. Multiple circumferentially distributed positioning grooves are formed on the upper end of the inner wall of each of the four adjustment columns. Positioning plates are rotatably mounted on the lower end of each of the four screws. Knobs are fixedly mounted on the upper end of each of the four screws. Multiple circumferentially distributed locking tooth grooves are formed on the lower end of each of the four adjustment columns. A spring piece is fixedly mounted on the upper end of one side of each of the four base posts.

[0008] Furthermore, the lower ends of the four base piles are respectively fixedly installed on the inner bottom surfaces of the front and middle sides of the UAV body, and the upper ends of the four adjustment rings are respectively fixedly installed on the inner top surfaces of the front and middle sides of the UAV body.

[0009] Furthermore, threaded holes are provided on both the front end and the middle of the upper side of the drone body, and the four screw rods pass through the four threaded holes respectively.

[0010] Furthermore, the internal shapes of the plurality of limiting grooves and the plurality of positioning grooves are identical.

[0011] Furthermore, the shapes of the four spring pieces and the shapes within the multiple toothed grooves are matched to each other.

[0012] Furthermore, an arm is fixedly installed on one side of each of the four adjustment columns.

[0013] This utility model has the following beneficial effects:

[0014] This utility model proposes a quadcopter drone frame assembly. By rotating the arm, the operator drives the adjustment column to rotate, thereby adjusting the horizontal angle of the arm and changing the drone's center of gravity. This adjusts the drone's center of gravity position, keeping it relatively balanced and facilitating flight control. Then, by rotating a knob, the operator moves a positioning plate into a positioning slot via a screw, thus fixing the arm angle and ensuring that the arm angle does not easily change during flight, guaranteeing flight stability.

[0023] 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.

[0024] Reference Figures 1-3 One embodiment of this utility model is a quadcopter drone frame assembly, including a drone body 1, with adjustment mechanisms 3 provided at the front and middle of both sides of the drone body 1, and an arm 2 provided on one side of each of the four adjustment mechanisms 3.

[0025] Specifically, it should be noted that the innovation of this utility model lies in the adjustment mechanism 3 connecting the robotic arm 2 and the drone body 1. The main structure of the robotic arm 2 and the drone body 1 remains unchanged and are both existing technologies.

[0026] Reference Figures 2-6 The four adjustment mechanisms 3 include four adjustment columns 301, four base posts 302, four adjustment rings 303, and four screws 304. The four adjustment columns 301 are movably sleeved on the four base posts 302. Limiting grooves 306 are opened on both sides of the inner wall of the four adjustment rings 303. Multiple circumferentially distributed positioning grooves 307 are opened on the upper end of the inner wall of the four adjustment columns 301. Positioning plates 305 are rotatably installed on the lower end of the four screws 304. Knobs 3010 are fixedly installed on the upper end of the four screws 304. Multiple circumferentially distributed locking tooth grooves 308 are opened on the lower end of the four adjustment columns 301. Spring pieces 309 are fixedly installed on the upper end of one side of the four base posts 302. The grooves of the multiple limiting grooves 306 and the multiple positioning grooves 307 have the same shape. The shape of the four spring pieces 309 matches the shape of the grooves of the multiple locking tooth grooves 308.

[0027] Specifically, when the operator rotates the arm 2, since the adjusting column 301 is movably sleeved on the base pile 302, the adjusting column 301 will rotate with the cylinder at the center of the base pile 302 as support. Secondly, the number and distribution angle of the multiple locking tooth grooves 308 and multiple positioning grooves 307 are the same. When the adjusting column 301 rotates, the spring piece 309 will be continuously compressed and then bounced into the locking tooth groove 308. In this way, the rotation angle of the adjusting column 301 is limited, so that there will always be two opposite slots of the multiple positioning grooves 307 at the same horizontal angle as the two limiting grooves 306, ensuring that the positioning plate 305 can move accurately into the positioning groove 307.

[0028] In addition, the height of the positioning plate 305 is the same as the length of the groove in the limiting groove 306. When the operator rotates the knob 3010 in the opposite direction, the screw 304 drives the positioning plate 305 to move upward into the limiting groove 306, releasing the fixing of the adjusting column 301. The operator can then adjust the machine arm 2. The limiting groove 306 acts as a limit. When the operator rotates the knob 3010, it ensures that the screw 304 will push the positioning plate 305 instead of making the positioning plate 305 rotate.

[0029] It should be noted that the height of the positioning plate 305 is longer than the length of the positioning groove 307. When the positioning plate 305 moves into the positioning groove 307, a part of its upper end will remain in the limiting groove 306. When the operator attempts to rotate the adjusting column 301, the limiting groove 306 will disengage the upper end of the positioning plate 305, thereby fixing the adjusting column 301.

[0030] Reference Figure 2 , Figure 3 , Figure 4 The lower ends of the four base posts 302 are fixedly installed on the inner bottom surfaces of the front and middle sides of the UAV body 1, respectively. The upper ends of the four adjusting rings 303 are fixedly installed on the inner top surfaces of the front and middle sides of the UAV body 1, respectively. Threaded holes 3011 are provided on the front and middle sides of the upper end of the UAV body 1. The bodies of the four screws 304 pass through the four threaded holes 3011, respectively. An arm 2 is fixedly installed on one side of each of the four adjusting posts 301.

[0031] Specifically, on the upper part of the drone body 1, there are scales around the four threaded holes 3011. The required adjustment angle of the arm 2 can be observed through these scales. The distribution and number of these scales are the same as the multiple positioning slots 307.

[0032] Working principle: The operator rotates the machine arm 2 to adjust the horizontal angle of the machine arm 2. When the machine arm 2 is rotated, the spring 309 will be briefly compressed and then spring up to the tooth groove 308, thereby simply limiting the adjustment angle of the adjusting column 301. After the adjustment is completed, the operator rotates the knob 3010 to drive the screw 304 to rotate. Through the thread transmission of the screw 304 rotating in the threaded hole 3011, the positioning plate 305 is driven to move down. At this time, the positioning plate 305 moves from the limiting groove 306 to the positioning groove 307, and the two sides of the positioning plate 305 will be locked in the two corresponding positioning grooves 307, thereby fixing the position of the adjusting column 301.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
