Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a compressed air landing mechanism for a UAV and the UAV itself. Background Technology

[0002] A drone, also known as an unmanned aerial vehicle or a remote-controlled aircraft, is an aircraft without any onboard personnel. It can be remotely controlled by a ground control station or fly autonomously according to a pre-programmed flight plan.

[0003] Currently, drones have a wide variety of applications, ranging from agricultural monitoring to urban patrols and disaster relief. However, due to the diverse outdoor environments, when drones encounter uneven ground for takeoff and landing, the irregular ground conditions may not only cause collision damage to the drone body, but may also cause the drone to tip over and be damaged, thus affecting the drone's lifespan. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when a drone encounters uneven ground for take-off and landing, it may be damaged by collision or rollover, which will affect the service life of the drone. Therefore, this invention proposes a compressed air landing drone take-off and landing mechanism and a drone.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A compressed air landing unmanned aerial vehicle (UAV) landing mechanism includes a landing box and a landing platform mounted on the landing box. A crossbar is fixedly connected inside the landing box, and a pressure-absorbing part is provided on the crossbar. When the landing platform is subjected to an external force, the pressure-absorbing part is used to buffer the landing platform's movement within the landing box. A support leg is provided on the landing box, and an adjusting member is provided on the support leg to drive the landing box to move up and down.

[0007] To reduce the impact force of the UAV landing on the landing platform, preferably, the pressure-reducing part includes two movable blocks slidably connected to a crossbar. A tension spring is sleeved on the crossbar, and the two ends of the tension spring are respectively fixedly connected to the two movable blocks. A crank is rotatably connected to the movable blocks. The landing platform is slidably installed in the landing box. The end of the crank away from the movable blocks is rotatably connected to the bottom of the landing platform. A compressive element is provided on the crossbar.

[0008] In order to guide the landing platform, preferably, guide grooves are provided on both sides of the inner wall of the landing box, and guide blocks are fixedly connected to both sides of the landing platform, and the guide blocks are slidably connected in the guide grooves in the longitudinal direction.

[0009] To further reduce the impact force of the UAV landing on the landing platform, the compressed air component includes a telescopic airbag sleeved on a crossbar. The two ends of the telescopic airbag are fixedly connected to the inner wall of the landing box and the surface of the moving block, respectively. The telescopic airbag is connected to an air inlet pipe and an air outlet pipe, and the air inlet end of the air inlet pipe and the air outlet end of the air outlet pipe both extend to the outside of the landing box. One-way valves are installed in both the air inlet pipe and the air outlet pipe.

[0010] To facilitate horizontal adjustment of the lifting mechanism, preferably, the adjusting component includes an adjusting tube rotatably connected to the bottom of the lifting box, and a lead screw fixedly connected to the top of the support leg, wherein the adjusting tube is threaded onto the lead screw, and a bubble level is fixedly installed on the lifting platform.

[0011] An unmanned aerial vehicle (UAV) includes a UAV body placed on top of a landing platform.

[0012] Compared with the prior art, this utility model provides a compressed air landing drone take-off and landing mechanism and a drone, which has the following beneficial effects:

[0013] 1. The air-cooled landing drone take-off and landing mechanism, through the setting of the landing box and landing platform, can provide horizontal support for the main body of the drone, so as to ensure that the main body of the drone can take off and land horizontally, avoiding the drone body from being bumped or damaged or overturned due to uneven ground, thereby improving the service life of the drone.

[0014] 2. The air-operated landing mechanism of this UAV, through the cooperation of the moving block, tension spring and crank, can significantly reduce the impact force generated when the UAV lands on the landing platform, so as to achieve buffer protection for the UAV and avoid damage to the UAV due to hard landing.

[0015] 3. The air-operated landing mechanism of this UAV, through the design of telescopic airbags, air intake pipes and exhaust pipes, can further reduce the impact force of the UAV body landing on the landing platform, thereby improving the buffer protection effect of the UAV body. It can also provide a certain damping force for the moving block, thereby reducing the rebound force generated by the tension spring, thus greatly improving the landing stability of the UAV body.

[0016] 4. The air-operated landing mechanism of this UAV, through the coordinated use of the adjusting tube, lead screw and support legs, allows users to easily adjust the height of the four corners of the landing box according to the environment, and the landing platform can be adjusted to a horizontal state by referring to the bubble level. This enables the mechanism to meet the landing requirements of UAVs in different operating environments, thereby improving the applicability of the landing mechanism.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model solves the problem in the prior art that when a drone encounters uneven ground for take-off and landing, it may be damaged by collision or rollover, which in turn affects the service life of the drone.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-5This utility model embodiment provides a compressed air landing drone landing mechanism, including a landing box 1, and a landing platform 2 installed on the landing box 1. The landing platform 2 is provided with landing markings to facilitate the drone landing on the landing platform 2. A crossbar 3 is fixedly connected inside the landing box 1, and a pressure buffer is provided on the crossbar 3. When the landing platform 2 is subjected to an external force, the pressure buffer is used to make the landing platform 2 perform buffering movement inside the landing box 1. A support leg 6 is provided on the landing box 1, and an adjusting component is provided on the support leg 6 to drive the landing box 1 to move up and down.

[0028] Specifically, during use, the landing box 1 and landing platform 2 provide horizontal support for the drone body 8, ensuring that the drone body 8 can take off and land horizontally. This prevents the drone body 8 from being damaged by bumps or tipping over due to uneven ground, thereby improving the service life of the drone. The cushioning section significantly reduces the impact force generated when the drone body 8 lands on the landing platform 2, providing buffer protection for the drone body 8 and preventing damage from hard landings. The adjustable parts allow users to easily adjust the height of the four corners of the landing box 1 according to the environment, and the landing platform 2 can be adjusted to a horizontal state by referring to the bubble level 7. This allows the mechanism to meet the take-off and landing requirements of the drone in different operating environments, thereby improving the applicability of the landing mechanism.

[0029] The pressure relief section includes two movable blocks 4 slidably connected to the crossbar 3. A tension spring 41 is sleeved on the crossbar 3. The two ends of the tension spring 41 are fixedly connected to the two movable blocks 4 respectively. A crank rod 42 is rotatably connected to the movable blocks 4. The landing platform 2 is slidably installed in the landing box 1. The end of the crank rod 42 away from the movable blocks 4 is rotatably connected to the bottom of the landing platform 2. A pressure component is provided on the crossbar 3.

[0030] Specifically, when the drone body 8 lands on the landing platform 2, the landing platform 2 moves downward. At the same time, the two moving blocks 4 move apart under the impact force and stretch the tension spring 41. Through the cooperation of the moving blocks 4, the tension spring 41 and the crank 42, the impact force generated by the drone body 8 landing on the landing platform 2 can be greatly reduced, so as to achieve buffer protection for the drone body 8, avoid damage to the drone body 8 due to hard landing, and help improve the service life of the drone body 8.

[0031] Guide grooves 22 are provided on both sides of the inner wall of the landing box 1, and guide blocks 21 are fixedly connected to both sides of the landing platform 2. The guide blocks 21 are longitudinally slidably connected in the guide grooves 22.

[0032] Specifically, by setting up the guide block 21 and the guide groove 22, the landing platform 2 can be guided to prevent it from deviating during movement.

[0033] The compressed air component includes a telescopic airbag 5 sleeved on the crossbar 3. The two ends of the telescopic airbag 5 are fixedly connected to the inner wall of the landing box 1 and the surface of the moving block 4, respectively. The telescopic airbag 5 is connected to an air inlet pipe 51 and an exhaust pipe 52. The air inlet end of the air inlet pipe 51 and the exhaust end of the exhaust pipe 52 both extend to the outside of the landing box 1. One-way valves are installed in both the air inlet pipe 51 and the exhaust pipe 52.

[0034] Specifically, when the main body 8 of the drone lands on the landing platform 2, the two moving blocks 4 move apart under the impact force and compress the telescopic airbag 5, so that the air in the telescopic airbag 5 is gradually discharged through the exhaust pipe 52. Through the setting of the telescopic airbag 5, the air intake pipe 51 and the exhaust pipe 52, the impact force of the main body 8 of the drone landing on the landing platform 2 can be further weakened, thereby improving the buffer protection effect of the main body 8 of the drone.

[0035] Furthermore, when the tension spring 41 returns to its original position, it drives the moving block 4 and the telescopic airbag 5 to return to their original position together, allowing outside air to slowly enter the telescopic airbag 5 through the air intake pipe 51. This provides a certain damping force to the moving block 4, thereby reducing the rebound force generated by the tension spring 41 and greatly improving the landing stability of the UAV body 8.

[0036] In addition, the two one-way valves allow the intake pipe 51 to be used only for intake, while the exhaust pipe 52 is used only for exhaust.

[0037] The adjusting components include an adjusting pipe 61 rotatably connected to the bottom of the lifting box 1, and a lead screw 62 fixedly connected to the top of the support leg 6. The adjusting pipe 61 is threadedly connected to the lead screw 62, and a bubble level 7 is fixedly installed on the lifting platform 2.

[0038] Specifically, by using the adjustment tube 61, lead screw 62 and support leg 6 together, users can easily adjust the height of the four corners of the landing box 1 according to the environment, and the landing platform 2 can be adjusted to a horizontal state by referring to the bubble level 7, so that the mechanism can meet the take-off and landing requirements of the UAV in different operating environments, thereby improving the applicability of the landing mechanism.

[0039] A drone includes a drone body 8, which is placed on top of a landing platform 2.

[0040] During the use of this compressed air landing drone, the landing mechanism and the drone are first placed on the ground, and the landing box 1 and landing platform 2 are adjusted to a horizontal state by adjusting the adjustment pipe 61 and the bubble level 7. Then the drone body 8 is placed on the landing platform 2 to perform the take-off operation.

[0041] Furthermore, when the drone body 8 lands on the landing platform 2, the landing platform 2 moves downward. At the same time, the two moving blocks 4 move apart under the impact force and stretch the tension spring 41. Through the cooperation of the moving blocks 4, the tension spring 41 and the crank 42, the impact force generated by the drone body 8 landing on the landing platform 2 can be greatly reduced, so as to achieve buffer protection for the drone body 8, avoid damage to the drone body 8 due to hard landing, and help improve the service life of the drone body 8.

[0042] Meanwhile, when the main body 8 of the drone lands on the landing platform 2, the two moving blocks 4 move apart under the impact force and compress the telescopic airbag 5, so that the air in the telescopic airbag 5 is gradually discharged through the exhaust pipe 52. Through the setting of the telescopic airbag 5, the air intake pipe 51 and the exhaust pipe 52, the impact force of the main body 8 of the drone landing on the landing platform 2 can be further weakened, thereby improving the buffer protection effect of the main body 8 of the drone.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
