[0002] A drone, or unmanned aerial vehicle, is essentially a flying robot. It does not require a pilot inside the aircraft; instead, it flies autonomously via remote control (ground station) or by relying on built-in programs.

[0003] For example, a non-contact building facade defect detection device, Chinese Patent Publication No. CN221725881U, includes a drone; a radar detection mechanism is mounted on the drone, including a radar detection component and a first rotating component, the first rotating component driving the radar detection component to rotate; a camera detection mechanism is mounted on the drone, including a visible light camera component, an infrared thermal imaging camera component, and a second rotating component, the second rotating component driving the visible light camera component and the infrared thermal imaging camera component to rotate; and an information storage component is located inside the drone.

[0004] Existing drones use bolts for mounting lidar, which requires tools for installation when removing or remounting the lidar, resulting in a significant amount of installation time. Therefore, an improved device is needed to address this issue. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides an embodiment of a UAV environment modeling and scanning camera module based on three-dimensional digitalization, including a lidar 2, a mounting device 3, and a positioning device 4. A covering device 5 is fixedly installed at the rear end of the positioning device 4, and the lidar 2 is fixedly installed at the front end of the positioning device 4. The positioning device 4 includes a positioning rod 8, a support base plate 9, a displacement plate 10, a return spring 11, a support cavity 12, a movable rod 13, an L-shaped bracket 14, and a positioning sleeve 15. The support cavity 12 is fixedly installed at both ends of the top of the support base plate 9. The movable rod 13 is slidably inserted into the inside of the support cavity 12. The displacement plate 10 is fixedly installed on the outer ring of the movable rod 13. The return spring 11 is fixedly installed between the displacement plate 10 and the inside of the support cavity 12 away from the displacement plate 10. The L-shaped bracket 14 is fixedly installed at the end of the movable rod 13 away from the displacement plate 10. The positioning sleeve 15 is symmetrically fixedly installed at the top of the rear end of the support base plate 9. The positioning rod 8 is fixedly installed at the end of the movable rod 13 away from the L-shaped bracket 14.

[0021] The mounting device 3 includes a lower edge bracket 6 and a side strip 7. The side strip 7 is symmetrically fixedly installed at the bottom of the outer ring of the lower edge bracket 6. It is installed at the bottom of the UAV 1 through the lower edge bracket 6, so that it can support the support base plate 9 for operation.

[0022] The covering device 5 includes bolts 16, a protective cover 17, a support base frame 18, and a connecting wing plate 19. The connecting wing plate 19 is fixedly installed on the top of both ends of the protective cover 17. The bolts 16 are threaded into the top of the connecting wing plate 19. The protective cover 17 is rotatably installed between the two support base frames 18. When the protective cover 17 is rotated upward, it can drive the internal limiting partition to contact the lever on the L-shaped bracket 14, so as to prevent the L-shaped bracket 14 from shifting when the UAV 1 is running.

[0023] The front end of the support base 18 is connected to the rear end of the support base plate 9. The lower edge bracket 6 is fixedly installed at the bottom center of the UAV 1. The lidar 2 is fixedly installed at the front end of the support base plate 9. The support base plate 9 is slidably sleeved on the outer ring of the side strip 7 and the lower edge bracket 6, which facilitates the docking and assembly of the support base plate 9 with the lower edge bracket 6 and the side strip 7.

[0024] The bottom end of the edge strip 7 is inclined at 45°, and a round hole is opened in the center of the side end of the edge strip 7 to facilitate the insertion of the positioning rod 8 into the interior of the edge strip 7.

[0025] The top center of the support substrate 9 has a mating groove that matches the lower edge bracket 6 and the side strip 7, allowing the support substrate 9 to mate with the lower edge bracket 6 and the side strip 7.

[0026] Working principle: In use, when the lidar 2 needs to be mounted, the lidar 2 is installed at the front end of the support base plate 9, which can move the support base plate 9 to the bottom center of the edge strip 7. The top of the support base plate 9 has a mating groove that matches the lower edge bracket 6 and the edge strip 7, allowing the support base plate 9 to slide onto the bottom of the lower edge bracket 6 and the edge strip 7. At the same time, the positioning rod 8 inside the support base plate 9 will contact the bottom end of the edge strip 7. The bottom end of the edge strip 7 is set at a 45° angle, and the end of the positioning rod 8 away from the L-shaped bracket 14 is set in an arc shape, which improves the smoothness of contact between the positioning rod 8 and the edge strip 7. Subsequently, when the slot inside the support substrate 9 is fully fitted onto the bottom end of the lower edge bracket 6 and the side strip 7, the positioning rod 8 can be aligned with the round hole inside the side end of the side strip 7. At this time, the elasticity of the return spring 11 will drive the displacement piece 10 to move and reset, so that the displacement piece 10 can drive the positioning rod 8 to move and insert into the round hole inside the side end of the side strip 7, which can restrict the support substrate 9 to the bottom end of the lower edge bracket 6, completing the mounting of the lidar 2. Then, the protective cover 17 can be flipped upwards until the protective cover 17 moves to cover the outer ring of the L-shaped bracket 14, thereby protecting the L-shaped bracket 14. At the same time, through the protective cover 17... Internally, symmetrically installed limiting partitions are used. A lever is installed at the end of the L-shaped bracket 14 furthest from the displacement plate 10. The limiting partition contacts the lever side of the top of the L-shaped bracket 14, preventing the L-shaped bracket 14 from sliding when the protective cover 17 covers it. Subsequently, the protective cover 17 can rotate the connecting wing plate 19 to be perpendicularly aligned with the positioning sleeve 15. The bolt 16 can then be tightened until it penetrates the connecting wing plate 19 and enters the threaded hole inside the positioning sleeve 15, thus fixing the protective cover 17 and preventing it from flipping backward. When the lidar 2 needs to be disassembled, the bolt can be... 16. Rotate in the opposite direction until bolt 16 is removed from the inside of connecting wing plate 19 and positioning sleeve 15, thereby releasing the protective cover 17. At this time, the protective cover 17 can be rotated to the rear end, so that the limiting partition inside the protective cover 17 can disengage from the lever on the L-shaped bracket 14. The user can hold the lidar 2 with one hand, and the thumb and forefinger of the other hand can push the lever on the L-shaped bracket 14 to move away from the end of the support base plate 9 until the positioning rod 8 is moved out from the inside of the side strip 7, thereby releasing the support base plate 9. Then, the user can move the support base plate 9 downward to disassemble the lidar 2 and complete the work.

[0027] 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.
