Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle protection, in particular to a landing protection device for an unmanned aerial vehicle. Background Art

[0002] A drone is an unmanned aircraft that usually consists of a flight control system and an autonomous navigation system, and can perform flight missions through remote control or preset navigation plans.

[0003] For example, the Chinese utility model patent (CN 220430574 U) discloses a device for protecting a drone from a fall, which includes a fuselage and legs, with legs distributed at the bottom of the fuselage. The device is characterized in that: a support plate is provided below the fuselage, and slide grooves are symmetrically provided on the support plate. A clamping assembly is slidably provided in each slide groove, and each clamping assembly can clamp the legs. A corrugated plate is provided at the bottom of the support plate, a shock absorbing plate is provided at the bottom of the corrugated plate, and a shock absorber is provided between the support plate and the shock absorbing plate. The utility model provides a corrugated plate and a shock absorbing plate at the bottom of the support plate to buffer the impact generated by the collision between the drone and the bottom surface when the drone falls. At the same time, a shock absorber is provided between the support plate and the shock absorbing plate to absorb the impact force between the drone and the bottom surface, thereby reducing the bouncing frequency of the corrugated plate, thereby achieving a protective effect when the drone lands.

[0004] However, in the above patent, the cushioning and shock-absorbing effect is only achieved through the shock-absorbing plate and the protrusions. However, when the drone malfunctions and falls, the impact force is too large, and the corrugated plate not only fails to achieve the cushioning effect, but also increases the height of the bounce, causing further damage to the drone. This patent cannot stabilize the drone in time, the drone will roll over, and the length of the buffer structure cannot be controlled. In addition, the structure is large in size and will block the drone from installing other equipment for operation. The utility model can achieve a good cushioning effect, can solve the problem of drone falling, and quickly complete the disassembly and assembly work. For this reason, a drone landing protection device is needed. Utility Model Content

[0026] The working assembly includes a connecting plate 2, the bottom of the frame 1 is provided with the connecting plate 2, the bottom of the connecting plate 2 is fixedly connected with a threaded column 3, and the outer wall of the threaded column 3 is spirally connected with a fixing plate 4;

[0027] The buffer assembly includes a sliding column 5, the bottom of the fixed plate 4 is fixedly connected to the sliding column 5, the outer wall of the sliding column 5 is slidably connected to the contraction column 6, the outer wall of the contraction column 6 is provided with a first spring 7, the bottom of the fixed plate 4 is rotatably connected to the telescopic column 8, the outer wall of the telescopic column 8 is provided with a second spring 9, and the bottom end of the contraction column 6 is fixedly connected to a positioning cone 10.

[0028] Among them, Figure 3 As shown, the fixed plate 4 and the sliding column 5 are fixedly connected, and the fixed plate 4 and the sliding column 5 are provided with thread grooves that match the threaded column 3, which is beneficial for the rotation of the threaded column 3, adjusting the distance between the connecting plate 2 and the fixed plate 4, and controlling the length of the support.

[0029] Among them, Figure 3 As shown, the retractable column 6 is provided with a sliding groove that matches the sliding column 5. The sliding column 5 forms a buffer structure with the retractable column 6 through the first spring 7, which is conducive to retracting the sliding column 5 into the groove of the retractable column 6, providing a buffer distance and reducing the impact force of the drone.

[0030] Among them, Figure 2 As shown, three groups of positioning cones 10 are provided, and the positions of the three groups of positioning cones 10 are symmetrically distributed about the center of the frame 1. The positioning cones 10 have a conical appearance, which is conducive to the positioning cones 10 being inserted into the ground when the drone falls, and can play a certain stabilizing effect, preventing the drone from falling and rolling multiple times.

[0031] Example 2

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, a pressing block 11 is provided at the bottom of the frame 1, a locking block 12 is fixedly connected to the top of the pressing block 11, a third spring 13 is fixedly connected to one side of the locking block 12, a connecting column 14 is slidably connected to the outer wall of the locking block 12, a fourth spring 15 is fixedly connected to one side of the pressing block 11, a supporting column 16 is fixedly connected to the bottom of the frame 1, a bracket 17 is fixedly connected to the bottom end of the supporting column 16, a connecting rod 18 is fixedly connected to the outer wall of the frame 1, a blade 19 is provided at one end of the connecting rod 18, and a camera 20 is fixedly connected to the top of the frame 1.

[0034] Among them, Figure 1 As shown, the frame 1 is provided with a sliding groove that matches the locking block 12. The locking block 12 forms a snap-fit ​​structure with the frame 1 through the pressing block 11 and the third spring 13, which is conducive to inserting the locking block 12 into the groove of the frame 1 to complete the fixation and facilitate installation.

[0035] When in use: First, when the drone lands, the positioning cone 10 will first contact the ground, so that the bottom of the positioning cone 10 is inserted into the ground, which has a certain stabilizing effect and prevents the drone from bouncing and rolling. The length of the support can be controlled by rotating the threaded column 3. At this time, the impact force of landing will cause the sliding column 5 to shrink into the groove of the contraction column 6, and the first spring 7 will play a buffering support effect. At the same time, the telescopic column 8 shrinks and relies on the second spring 9 to play an elastic support effect, which can buffer the side, reduce the impact force, and protect the drone equipment;

[0036] Finally, the user inserts the connecting column 14 into the groove at the bottom of the frame 1, and the locking block 12 shrinks back into the groove of the connecting column 14. When the position is reached, the locking block 12 pops out from the groove of the connecting column 14 by the elastic force of the third spring 13, and is inserted into the slot of the frame 1 to complete the fixation. Then, the locking block 12 shrinks back into the groove of the connecting column 14 by pressing the pressing block 11, and the connecting column 14 can be quickly installed and disassembled, which is convenient for its inspection and maintenance.
