Description

Technical Field

[0001] This utility model relates to the field of road inspection technology, and more specifically, it relates to a landing base for a road inspection drone. Background Technology

[0002] In the field of road inspection, drones have become a core tool for road condition monitoring, rapid defect detection, and emergency rescue reconnaissance due to their advantages of flexibility, efficiency, and wide coverage. To ensure that drones can land stably in complex outdoor environments such as roadsides, bridges, and suburban sections, and to avoid the aircraft tipping over or the propeller being damaged due to uneven ground or debris accumulation, the industry generally uses landing bases as auxiliary equipment.

[0003] An existing road inspection drone landing base has been found to have the following issues during use:

[0004] After landing, the drone remains completely exposed to the external environment, making it unable to withstand the erosion and damage caused by the complex outdoor environment. This seriously affects the drone's lifespan and operational reliability. Furthermore, rainwater and dew can easily splash directly onto the exposed drone body and electronic components such as batteries, sensors, and circuit boards, causing short circuits and corrosion of metal parts. The failure rate increases significantly, especially during the rainy season or in high humidity environments, resulting in poor practicality. Utility Model Content

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0028] Please see Figure 1-5 A landing base for a road inspection drone includes a landing platform 1. An annular plate 2 is slidably attached to the outer side of the landing platform 1. A base 3 is provided at the bottom of the annular plate 2. A lifting mechanism is provided at the top of the base 3. The top of the base 3 is connected to the bottom of the landing platform 1 through the lifting mechanism. A reserved hole is provided at the top right end of the inner side of the annular plate 2. A cover plate 4 is slidably attached to the reserved hole of the annular plate 2. The outer side of the cover plate 4 is respectively attached to one end of the inner side of the corresponding annular plate 2. A mounting frame 5 is provided at the right end of the cover plate 4. A U-shaped groove is provided at the left end of the mounting frame 5. The front and rear sides of the U-shaped groove of the mounting frame 5 are respectively slidably attached to one end of the corresponding annular plate 2. A sliding component is provided at the front end of the bottom of the mounting frame 5.

[0029] In this embodiment, when the drone is about to land on the base, the lifting mechanism at the top of the base 3 is activated. The lifting mechanism drives the landing platform 1 to move upward. The outer side of the landing platform 1 slides along the inner side of the annular plate 2 until the top of the landing platform 1 is higher than the top of the annular plate 2, so that the drone can land accurately on the landing platform 1.

[0030] After the drone lands, the lifting mechanism moves the landing platform 1 downwards. The landing platform 1 carries the drone into the inner side of the ring plate 2 until the bottom of the landing platform 1 fits into the matching position of the lifting mechanism, thus completing the action of the drone entering the inner side of the ring plate 2.

[0031] Activate the sliding component at the bottom front end of the mounting bracket 5. The sliding component drives the mounting bracket 5 to slide along one end of the annular plate 2. The front and rear sides of the U-shaped groove at the left end of the mounting bracket 5 slide along the corresponding ends of the annular plate 2. At the same time, the mounting bracket 5 drives the cover plate 4 to slide along the inner side of the reserved hole in the annular plate 2. Until the cover plate 4 completely covers the reserved hole in the annular plate 2, the outer side of the cover plate 4 is tightly fitted with one end of the inner side of the annular plate 2, forming a closed protection for the UAV inside the annular plate 2.

[0032] More specifically, when the drone enters the inner side of the annular plate 2 and the cover plate 4 needs to be closed for protection, the second motor 15 on the top of the fixing base 17 is activated. The fixing base 17 is fixed to the top right side of the front end of the annular plate 2, providing stable support for the second motor 15. The rear output end of the second motor 15 drives the connecting gear 18 to rotate. The top of the connecting gear 18 meshes with the bottom of the rack plate 16 at the bottom front end of the mounting frame 5. When the connecting gear 18 rotates, it drives the rack plate 16 to move laterally. The rack plate 16 drives the mounting frame 5 to move synchronously. The left end of the mounting frame 5 drives the cover plate 4 to slide along the inner side of the reserved hole in the annular plate 2 until the cover plate 4 completely covers the reserved hole, forming protection.

[0033] Please see Figure 1 and Figure 4 As one embodiment of the lifting mechanism: the lifting mechanism includes a mounting block 6, a driving component is provided at the bottom of the inner side of the annular plate 2, the mounting block 6 is provided on the inner side of the annular plate 2 through the driving component, a first sliding groove is provided at the top of the base 3, and a connecting block 7 is slidably provided in the first sliding groove of the base 3, and the top of the connecting block 7 is connected to the bottom of the mounting block 6. A set of first connecting rods 8 are hinged at both ends of the mounting block 6 through hinges, and sliding blocks 9 are hinged at the other ends of the two sets of first connecting rods 8 through hinges. The bottoms of the two sets of sliding blocks 9 are respectively slidably attached to one side of the top of the base 3. A support plate 10 is provided at the top of the two sets of sliding blocks 9. Second connecting rods 11 are hinged on the left and right sides of the top of the two sets of support plates 10 through hinges, and the bottom of the landing platform 1 is evenly hinged to the other ends of the four sets of second connecting rods 11 through hinges.

[0034] Specifically, when the landing platform 1 and the drone need to enter the inner side of the annular plate 2, the drive component at the bottom of the inner side of the annular plate 2 is activated. The drive component drives the mounting block 6 to move along the inner side of the annular plate 2. The connecting block 7 at the bottom of the mounting block 6 slides laterally along the first slide groove at the top of the base 3, providing guidance for the movement of the mounting block 6. When the mounting block 6 moves, the two sets of first connecting rods 8 hinged at its front and rear ends rotate accordingly. The other end of the first connecting rod 8 drives the sliding block 9 to slide along one side of the top of the base 3. The support plate 10 at the top of the sliding block 9 moves synchronously with the sliding block 9. When the support plate 10 moves, the four sets of second connecting rods 11 hinged on the left and right sides of its top rotate synchronously. The other end of the second connecting rod 11 drives the landing platform 1 to move downward. The landing platform 1, carrying the drone, gradually enters the inner side of the annular plate 2.

[0035] Please refer to Figures 2-4As a further embodiment of the drive assembly: the drive assembly includes a first motor 12, a connecting screw 13 is rotatably provided on the bottom inner side of the annular plate 2, the first motor 12 is provided on the bottom right end of the annular plate 2, the left output end of the first motor 12 passes through the annular plate 2 and is connected to the right end of the connecting screw 13, a threaded cylinder 14 is threadedly connected to the outside of the connecting screw 13, and a reserved hole is provided on the mounting block 6, the inside of the reserved hole of the mounting block 6 is connected to the outside of the threaded cylinder 14.

[0036] Specifically, when the lifting mechanism is needed to move the landing platform 1, the first motor 12 at the bottom right end of the annular plate 2 is activated. The output end of the first motor 12 on the left side passes through the annular plate 2 and drives the connecting screw 13 to rotate. The outer side of the connecting screw 13 rotates stably along the bottom inner side of the annular plate 2. Since the threaded cylinder 14 connected to the outer side of the connecting screw 13 is connected to the inner side of the reserved hole of the mounting block 6, when the connecting screw 13 rotates, the threaded cylinder 14 drives the mounting block 6 to move along the inner side of the annular plate 2. The movement of the mounting block 6 then drives the first connecting rod 8, the sliding block 9, and the second connecting rod 11 to move together, ultimately realizing the lifting and lowering of the landing platform 1, and driving the UAV into or out of the inner side of the annular plate 2.

[0037] In summary, the overall equipment is in use (or running):

[0038] When the drone is preparing to land, the first motor 12 at the bottom right end of the annular plate 2 is activated. The first motor 12 drives the connecting screw 13 on the inner side of the annular plate 2 to rotate. The threaded cylinder 14 drives the mounting block 6 to move. The connecting block 7 at the bottom of the mounting block 6 slides along the first slide groove of the base 3. The mounting block 6 drives the first connecting rod 8 at the front and rear ends to rotate, pushing the sliding block 9 to move. The second guide block 21 at the bottom of the sliding block 9 slides along the second slide groove of the base 3. The support plate 10 on the sliding block 9 drives the four sets of second connecting rods 11 to rotate, raising the landing platform 1 to a height above the top of the annular plate 2. The drone lands on the landing platform 1.

[0039] Then, the first motor 12 is started in reverse, the connecting screw 13 rotates in reverse, the mounting block 6 drives the various components to move together, the landing platform 1 lowers the drone into the inner side of the annular plate 2, the first motor 12 is turned off to lock the height, the second motor 15 on the fixed seat 17 is started, the second motor 15 drives the connecting gear 18 to rotate, meshing with the rack plate 16 at the bottom of the mounting frame 5, the first guide block 19 of the U-shaped groove of the mounting frame 5 slides along the slide groove of the annular plate 2, driving the cover plate 4 to slide along the reserved hole of the annular plate 2 until the positioning block 20 at the left end of the cover plate 4 is inserted into the positioning hole of the annular plate 2, completing the sealing protection.

[0040] When the drone needs to be removed, the second motor 15 is started in reverse to open the cover 4; then the first motor 12 is started, the landing platform 1 is raised after landing, and the drone can take off or be removed. Finally, the first motor 12 is operated in reverse to reset the landing platform 1.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
