Detailed Implementation
[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0025] like Figure 1-5As shown, an adjustable mounting frame drone includes a body assembly 1, an adjustment assembly 2, and a mounting assembly 3. The body assembly 1 includes a drone body 11, with wing plates 12 connected to all four sides of the drone body 11. A propeller 14 is connected to the top of the wing plate 12 at the end away from the drone body 11. A shooting device 13 is installed on the lower front part of the drone body 11 using a quick-release buckle structure. A mounting bracket 15 is connected to the bottom surface of the drone body 11.
[0026] The shooting device 13 includes a high-definition camera and a gimbal with omnidirectional rotation and a pitch angle range of -90° to +30°. The camera is used to capture high-definition images and videos during use, and the gimbal allows for precise adjustment of the camera's angle to meet different shooting needs. Four propellers 14 are provided, symmetrically arranged about the longitudinal centerline of the drone body 11.
[0027] The adjusting assembly 2 includes an adjusting box 21, a motor 23, and a lead screw 24. The adjusting box 21 has symmetrically arranged adjusting grooves 22 at its bottom. A linkage block 25 is provided on the inner side of the adjusting box 21, and symmetrical clearance grooves 26 are provided on the inner side of the linkage block 25. Slider blocks 27 are symmetrically connected to both ends of the linkage block 25. The inner wall of the adjusting box 21 is provided with a slide rail 28 that slides with the sliders 27. The motor 23 is connected to the outer wall of the adjusting box 21 via a bracket.
[0028] The mounting assembly 3 includes a mounting frame 31, a connecting rod 34, and a locking nut 36. The top of the mounting frame 31 is connected to a plug plate 32, and the plug plate 32 has a sliding groove 33. Both ends of the connecting rod 34 are provided with external threads 35.
[0029] The adjustment box 21 is connected to the mounting frame 15, which is a telescopic bracket. The mounting frame 15 is used to adjust the height of the adjustment box 21, thereby adjusting the height of the mounting frame 31.
[0030] By adjusting the setting of the sliding groove 22, a guide groove is provided for the insertion of the mounting frame 31 into the adjustment box 21. Simultaneously, it serves as a sliding channel for the mounting frame 31 during adjustment. The surface of the adjusting groove 22 is polished to ensure that the mounting frame 31 can slide easily and smoothly. One end of the lead screw 24 penetrates the wall of the adjustment box 21 and extends to be electrically connected to the output end of the motor 23 via a flexible coupling. The end of the lead screw 24 away from the motor 23 is rotatably connected to the inner wall of the adjustment box 21 via a bearing. The lead screw 24 passes through the linkage block 25 and is threadedly rotatably connected to it. When adjustment of the mounting frame 31 is required, the motor 23 is started. The motor 23 performs precise forward and reverse rotation control according to a preset program, driving the lead screw 24 to rotate. This, in turn, through the threaded transmission between the lead screw 24 and the linkage block 25, enables the lateral movement of the linkage block 25, thereby achieving adjustment of the usage position of the mounting frame 31. The inner wall of the adjustment box 21 is symmetrically connected with slide rails 28. The end of the slider 27 away from the linkage block 25 is located inside the slide rail 28, and the slider 27 is slidably connected to the slide rail 28. By sliding the slider 27 inside the slide rail 28, the stability and accuracy of the linkage block 25 during movement are ensured, shaking and deviation are reduced, and the adjustment accuracy of the mounting frame 31 is ensured.
[0031] The front cross-section of the mounting frame 31 is U-shaped. A symmetrically connected, integrally formed plug-in plate 32 is attached to the top of the mounting frame 31. The dimensions of the sliding groove 33 match the dimensions of the connecting rod 34. When installing the mounting frame 31, precisely align the plug-in plate 32 with the adjusting groove 22, insert it smoothly, and then push the mounting frame 31 upwards until the plug-in plate 32 is inserted into the clearance groove 26, until the top of the mounting frame 31 is tightly fitted with the bottom of the linkage block 25, thus achieving a secure assembly connection between the mounting frame 31 and the linkage block 25. Two connecting rods 34 are provided. A through-hole slot for inserting the connecting rods 34 is provided on the side of the adjusting box 21 near the motor 23. A threaded seat 37 is connected to the inner wall of the adjusting box 21, and an internal thread matching the external thread 35 is provided on the inner side of the threaded seat 37. After the plug plate 32 passes through the linkage block 25, the two connecting rods 34 are precisely inserted into the through-hole slots of the adjustment box 21. The connecting rods 34 are pushed to slide smoothly into the adjustment box 21, and at the same time, the connecting rods 34 are accurately passed through the corresponding sliding grooves 33. Then, a special tool is used to rotate the connecting rods 34 to make a tight threaded connection with the threaded seat 37. Finally, the locking nut 36 is used to double lock the connecting rods 34. The mounting frame 31 is installed on the adjustment box 21 through the linkage block 25, so that it can move along the adjustment slide 22. This allows the position of the mounting frame 31 to be adjusted on the adjustment box 21 according to the usage requirements and the center of gravity distribution of the UAV, so that it can maintain a good balance during flight. This is especially important when carrying payloads of different weights and sizes, and can effectively improve the flight stability and safety of the UAV.
[0032] The working principle of this utility model is as follows: During use, inspect the drone body 11; ensure each wing plate 12 is securely connected to the drone body 11; inspect the shooting device 13; ensure the camera lens is clean and free of stains; ensure all gimbal connections are stable; observe that the adjustment box 21 is undamaged; and ensure the adjustment groove 22 is free of foreign objects and has smooth walls. Open the adjustment box 21 and check that the linkage block 25, slider 27, and slide rail 28 are properly connected; ensure the slider 27 slides smoothly within the slide rail 28. When installing the mounting frame 31, precisely align the connector plate 32 with the adjustment groove 22 and insert it smoothly. Then push the mounting frame 31 upwards, causing the connector plate 32 to insert into the clearance groove 26 until the top of the mounting frame 31 is tightly fitted with the bottom of the linkage block 25, thus achieving a secure assembly connection between the mounting frame 31 and the linkage block 25. After the connector plate 32 passes through the linkage block 25, precisely insert the two connecting rods 34 into the through-hole slots of the adjustment box 21, and push the connecting rods 34 smoothly into the adjustment box 21. The connecting rod 34 is accurately passed through the corresponding sliding groove 33. Then, a special tool is used to rotate the connecting rod 34 to make it tightly threaded with the threaded seat 37. Finally, the locking nut 36 is used to double-lock the connecting rod 34. The mounting bracket 31 is mounted on the adjustment box 21 through the linkage block 25, allowing it to move along the adjustment groove 22. This facilitates adjusting the position of the mounting bracket 31 on the adjustment box 21 according to usage requirements and the center of gravity distribution of the UAV, ensuring good balance during flight. This is especially important when carrying payloads of different weights and sizes, effectively improving the flight stability and safety of the UAV. When adjustment of the mounting bracket 31 is required, the motor 23 is started. The motor 23 performs precise forward and reverse control according to a preset program, driving the lead screw 24 to rotate. This, in turn, via the threaded transmission between the lead screw 24 and the linkage block 25, enables the linkage block 25 to move laterally, thereby adjusting the position of the mounting bracket 31. As the lead screw 24 rotates under the action of the motor 23, the linkage block 25 moves laterally under the threaded transmission of the lead screw 24 and the guidance of the slider 27. Simultaneously, the sliding of the slider 27 within the slide rail 28 ensures the stability and accuracy of the linkage block 25 during movement, reducing wobbling and deviation, and ensuring... The adjustment precision of the mounting bracket 31 is achieved through the setting of the adjustment groove 22, which provides a guide groove for the mounting bracket 31 to be inserted into the adjustment box 21 and also serves as a sliding channel for the mounting bracket 31 during adjustment. The surface of the adjustment groove 22 is polished to ensure that the mounting bracket 31 can slide easily and smoothly. The mounting bracket 15 is used to adjust the height of the adjustment box 21, thereby achieving the adjustment of the height of the mounting bracket 31. The camera is used to capture high-definition images and videos during use. The gimbal is used to facilitate precise adjustment of the camera's angle during use to meet different shooting needs.
