[0009] Furthermore, the plurality of guide rods all slide inside the guide hole;
[0010] Through the above technical solution, this design helps to maintain the stability of the landing gear during landing.
[0011] Furthermore, the lower ends of the outer walls of the two sliding rings are rotatably connected to the second rotating rod;
[0012] Through the above technical solution, the rotating connection allows the sliding ring to rotate flexibly on the second rotating rod, so that the angle and position of the landing gear can be adjusted according to different landing conditions, thereby increasing the adjustment range of the landing gear.
[0013] Furthermore, the rear ends of the two installation boxes are fixedly connected to a protection box;
[0014] The above technical solution helps to dissipate heat from the servo motor, prevent overheating, and extend the service life of the servo motor.
[0015] Furthermore, the front ends of the two inner walls of the protection box are fixedly connected to the servo motor;
[0016] Through the above technical solution, the protection box helps to maintain the performance of the servo motor by protecting the servo motor from damage.
[0017] Furthermore, both ends of the two bidirectional threaded rods are rotatably connected to the installation box;
[0018] Through the above technical solution, the friction between the threaded rod and the installation box is reduced, the wear is reduced, and the service life of the component is extended.
[0019] Furthermore, rectangular grooves are provided at both ends of the two installation boxes;
[0020] Through the above technical solution, the rectangular groove provides a positioning and fixing position for the first rotating rod.
[0021] Furthermore, the output ends of the two servo motors are fixedly connected to one end of the bidirectional threaded rod;
[0022] Through the above technical solution, the automated motor drive reduces the need for manual adjustment of the landing gear.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Reference Figure 1-5 , a specific implementation method provided by the utility model:
[0035] A cushioned landing assembly for a drone comprises a mounting plate 1 and a connecting plate 17. Two support rods 2 are fixedly connected to both sides of the lower end of the mounting plate 1. The lower ends of the multiple support rods 2 are fixedly connected to mounting boxes 3. The inner walls of the two mounting boxes 3 are provided with bidirectional threaded rods 5. Both ends of the outer walls of the two bidirectional threaded rods 5 are sleeved with threaded sleeves 6. Both sides of the outer walls of the multiple threaded sleeves 6 are rotatably connected to first rotating rods 7. One end of the multiple first rotating rods 7 is rotatably connected to an expansion plate 8. The rear ends of the two mounting boxes 3 are provided with Servo motor 4, multiple guide holes 19 are provided at the four corners of the upper end of the mounting plate 1, a slide groove 11 is provided in the middle of the upper end of the mounting plate 1, sliders 12 are slidably connected to both sides of the inner wall of the slide groove 11, and the upper ends of the two sliders 12 are rotatably connected to the second rotating rod 13, a plurality of guide rods 18 are fixedly connected to the four corners of the lower end of the connecting plate 17, a slide rod 16 is fixedly connected to the middle of the inner wall of the connecting plate 17, and sliding rings 14 are slidably connected to both sides of the outer wall of the slide rod 16, and a spring 15 is fixedly connected between the two sliding rings 14;
[0036] The design of the unfolding plate 8 effectively increases the contact area with the ground, which helps to disperse the overall weight of the drone during landing, significantly reduces the pressure on the ground, and reduces potential damage to the ground. At the same time, it can effectively avoid tipping or rolling during landing due to too little pressure, thereby improving landing stability. Through the mutual cooperation between the spring 15, the sliding ring 14, the sliding rod 16, the second rotating rod 13, the slider 12, and the slide groove 11, the drone fixed at the upper end of the mounting plate 1 can be effectively buffered when subjected to vibration, thereby effectively reducing the damage to the internal components of the drone caused by vibration and increasing the service life of the drone.
[0037] Multiple guide rods 18 all slide inside the guide holes 19. This design helps to maintain the stability of the landing gear during landing. The lower ends of the outer walls of the two sliding rings 14 are rotatably connected to the second rotating rod 13. The rotating connection allows the sliding rings 14 to flexibly rotate on the second rotating rod 13, so that the angle and position of the landing gear can be adjusted according to different landing conditions, increasing the adjustment range of the landing gear. The rear ends of the two mounting boxes 3 are fixedly connected to the protective box 9, which helps to dissipate heat from the servo motor 4, prevent overheating, and extend the service life of the servo motor 4. The front ends of the inner walls of the two protective boxes 9 are fixedly connected to the servo motor 4. By protecting the servo motor 4 from damage, the protective box 9 helps to maintain the performance of the motor. Both ends of the two bidirectional threaded rods 5 are rotatably connected to the mounting box 3, reducing the friction between the bidirectional threaded rods 5 and the mounting box 3, reducing wear and extending the service life of the components. Rectangular grooves 10 are provided at both ends of the two mounting boxes 3. The rectangular grooves 10 provide a positioning and fixing position for the first rotating rod 7. The output ends of the two servo motors 4 are fixedly connected to one end of the bidirectional threaded rod 5. The automated motor drive reduces the need for manual adjustment of the landing gear.
[0038] Working principle: It is used by connecting the mounting plate 1 to the lower end of the drone. When the drone is ready to land, the servo motor 4 starts and drives the bidirectional threaded rod 5 to rotate. This rotational motion is transmitted to the first rotating rod 7 through the threaded sleeve 6, causing the deployment plate 8 to deploy outward, thereby increasing the contact area with the ground. This design helps to disperse the weight of the drone, reduce the pressure on the ground, and effectively absorb the impact force during landing. At the same time, it can effectively avoid tipping or rolling during landing due to too little pressure, thereby improving landing stability. At the same time, the guide rod 18 slides smoothly inside the guide hole 19, and the slider 12 is slidably connected in the slide groove 11, and the lower end of the outer wall of the sliding ring 14 is rotatably connected to the second rotating rod 13, so that the landing gear can effectively reduce the vibration caused by ground impact during landing. When the drone is ready to take off, the servo motor 4 rotates in the opposite direction to drive the bidirectional threaded rod 5 to rotate, driving the deployment plate 8 to retract.
[0039] Finally, it should be noted that the above is only a preferred specific implementation method of the present invention and is not intended to limit the present invention.
