[0035] Example 1

[0036] Reference Figures 1 to 4 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0037] 100 racks;

[0038] Support unit 200 is mounted on frame 100 and is used to adapt and support frame 100. Buffer assembly 300 is mounted on support unit 200 and is used to reduce impact on frame 100.

[0039] Air-bombing assembly 400 is mounted on the frame 100 and is used to clean the landing position of the frame 100.

[0040] In use, the support unit 200 can adaptively adjust the support mode according to the required landing ground, which is convenient for the drone to land on different ground surfaces. The buffer component 300 enables the drone to convert the impact into elastic deformation energy at the moment of contact with the ground, reducing its vibration and improving the landing stability of the drone. The air impact component 400 works with the support unit 200 to compress and generate airflow, which effectively blows away the gravel and debris in the landing area and avoids affecting the landing of the drone.

[0041] Example 2

[0042] Reference Figures 1 to 4 This is the second embodiment of the present invention, which differs from the previous embodiment in that...

[0043] The support unit 200 includes a cross-shaped plate 201, which is slidably connected to the frame 100. An electric push rod 202 is fixedly connected to the bottom surface of the frame 100. The telescopic end of the electric push rod 202 is fixedly connected to the top surface of the cross-shaped plate 201. Multiple support rods 203 are slidably connected to the cross-shaped plate 201. A support block 204 is fixedly connected to the bottom end of each of the multiple support rods 203. A stop block 205 is fixedly connected to the top end of each of the multiple support rods 203. Two base plates 206 are fixedly connected to the bottom surface of the frame 100.

[0044] The linkage between the cross-shaped plate 201 and the electric push rod 202 enables adaptive adjustment of take-off and landing height. The electric push rod 202 pushes the cross-shaped plate 201 to slide, driving the support rod 203 and support block 204 to rise and fall, adapting to different terrain heights. It can also flexibly switch between landing on hard and soft ground. When landing on hard ground, the electric push rod 202 is activated, and vice versa. The sliding cooperation between the multiple support rods 203 and the cross-shaped plate 201 can distribute the load on the fuselage. The frame 100 is used in conjunction with the UAV, and the UAV is mounted on the frame 100. This is existing technology and will not be described in detail here.

[0045] Specifically, the buffer assembly 300 includes multiple buffer sleeves 301, each of which is fitted onto a corresponding support rod 203. The multiple buffer sleeves 301 are fixedly connected to the cross-shaped plate 201. Multiple support blocks 204 and the bottom surfaces of the two base plates 206 are fixedly connected with anti-slip pads 302. The arms of the multiple support rods 203 are fixedly connected with top blocks 303.

[0046] With the cooperation of the buffer sleeve 301 and the top block 303, when the support block 204 touches the ground, the top block 303 squeezes the buffer sleeve 301 to produce elastic deformation, absorbs the impact energy of landing, and reduces the vibration damage of the frame 100. Meanwhile, the anti-slip pad 302 increases the ground friction and prevents the drone from sliding.

[0047] Specifically, the air-cushioning assembly 400 includes multiple connecting blocks 401, all of which are fixedly connected to the cross-shaped plate 201. Each of the multiple connecting blocks 401 is fixedly connected to a telescopic airbag 402, which is also fixedly connected to the cross-shaped plate 201. The bottom surface of each of the multiple telescopic airbags 402 is fixedly connected to an air outlet pipe 403, which passes through the corresponding connecting block 401. Each of the multiple telescopic airbags 402 is fixedly connected to an air inlet 404.

[0048] When in use, when the cross-shaped plate 201 is pushed down by the electric push rod 202, the telescopic airbag 402 is squeezed, causing the internal gas to be ejected through the air outlet pipe 403, which facilitates the clearing of gravel and debris at the landing position and improves the safety of take-off and landing in complex terrain. The air inlet 404 ensures that the airbag is automatically replenished when it expands.

[0049] Example 3

[0050] Reference Figures 2 to 4 This is the third embodiment of the present invention, which differs from the previous embodiment in that...

[0051] One-way valves 4031 are fixedly connected to multiple air outlet pipes 403 and air inlets 404, and the air outlets of multiple air outlet pipes 403 are all facing the lower side of the corresponding support block 204.

[0052] The one-way valve 4031 ensures that the air outlet pipe 403 sprays air in one direction and the air inlet 404 replenishes air in one direction, avoiding airflow backflow. The air outlet faces the lower side of the support block 204, which can accurately blow away debris at the landing point.

[0053] Specifically, two illumination lamps 2011 are fixedly connected to the bottom surface of the cross-shaped plate 201, and the two illumination lamps 2011 are arranged symmetrically.

[0054] The 2011 illumination lamp can provide uniform lighting during takeoff and landing, covering blind spots in the landing area and assisting the flight control system or operators in clearly identifying ground obstacles, slopes, and other conditions.

[0055] Specifically, the two side surfaces of the multiple top blocks 303 are respectively in contact with the corresponding support blocks 204 and buffer sleeves 301.

[0056] The top block 303 is movably fitted to the support block 204 and the buffer sleeve 301 on both sides, which can accurately transfer the load to the buffer sleeve 301 during take-off and landing impacts, and evenly disperse the impact force through surface contact to avoid local stress concentration.

[0057] Specifically, both ends of the two base plates 206 are set with an arc-shaped structure, and positioning rods 2061 are fixedly connected to the surfaces of the two base plates 206 that are far apart from each other.

[0058] When in use, the arc-shaped structure at both ends of the base plate 206 can reduce ground scraping and airflow resistance during take-off and landing, and the positioning rod 2061 can enhance the stability of the drone after being inserted into the ground.

[0059] During operation, when the drone is preparing to land, the electric push rod 202 is activated. Its telescopic end pushes the cross-shaped plate 201 to slide downwards along the frame 100, causing the support rod 203 to move downwards, so that the support block 204 is in contact with a relatively hard ground, providing support for landing. During landing, at the moment the support block 204 contacts the ground, the buffer sleeve 301 comes into play. Since multiple support rods 203 are slidably connected to the cross-shaped plate 201, when the support block 204 is impacted, the support rods 203 can slide upwards relative to the cross-shaped plate 201, causing the top block 303 to compress the buffer sleeve 301, converting the impact force into a buffer. The elastic deformation energy of 301 reduces the impact on the frame 100. When the support block 204 descends, the top block 303 moves upward with the support rod 203, squeezing the telescopic airbag 402. After the telescopic airbag 402 is squeezed, the internal gas is discharged through the air outlet pipe 403. Since the air outlet of the air outlet pipe 403 faces the lower side of the support block 204, the high-pressure airflow can effectively blow away the debris at the landing position, thus clearing the landing area and preventing gravel from affecting the landing of the drone. The one-way valve 4031 at the air inlet 404 ensures that the gas can only flow in one direction. When the telescopic airbag 402 recovers its deformation, it draws in air to prepare for the next compression and jetting.

[0060] When landing in a softer position, the electric push rod 202 does not need to be activated, allowing the anti-slip pad 302 on the bottom surface of the base plate 206 to contact the ground, making it easier for the drone to land on different ground surfaces. The illumination lights 2011 on the bottom surface of the cross-shaped plate 201 are turned on during the landing process. The symmetrically arranged lights can clearly illuminate the landing area and help judge the ground conditions. The arc-shaped structure at both ends of the base plate 206 helps to smoothly pass over obstacles during landing, and the positioning rod 2061 can cooperate with the ground structure to further enhance the landing stability.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
