Description

Technical Field

[0001] This utility model relates to the field of drone accessories technology, specifically a drone landing gear shock absorption device. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are commonly referred to simply as "drones." A UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control system. It can also be operated autonomously, either fully or intermittently, by an onboard computer. Landing gear is a crucial component of a UAV, its main functions being to support the UAV during takeoff and to provide cushioning during landing.

[0003] According to patent publication number CN213384690U, a shock-absorbing device for landing gear of unmanned aerial vehicles (UAVs) is disclosed. The shock-absorbing device for UAVs includes a UAV body, a rotating shaft is disposed on the surface of the UAV body, a propeller is disposed on the surface of the rotating shaft, and a retaining ring is disposed on the top of the rotating shaft.

[0004] The above solution reduces the impact force on the drone when it lands, preventing damage to the drone's fuselage and increasing its service life. However, the solution still has certain limitations: the landing gear and the drone body are integrated in the above device. Although this design ensures the overall stability of the drone, it also brings a significant drawback: the integrated design makes the drone larger, making it inconvenient for users to store and transport. To address this, we provide a drone landing gear shock absorption device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a shock absorption device for the landing gear of unmanned aerial vehicles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing device for unmanned aerial vehicle (UAV) landing gear, including a UAV body mounted above the UAV body, a set of support legs mounted on the bottom surface of the UAV body, an installation mechanism on the UAV body for connecting the UAV body and the UAV body, a shock-absorbing mechanism on the support legs, a set of motors mounted on the upper surface of the UAV body, a rotating shaft fixedly connected to the output end of the motors, and a set of propeller blades fixedly connected to the outer surface of the rotating shaft.

[0007] Furthermore, the installation mechanism includes a limiting groove, which is formed in the inner bottom wall of the drone body. A second rotating shaft is rotatably connected inside the drone body. A rotating handle is fixedly connected to the upper surface of the second rotating shaft, and a first bevel gear is fixedly connected to the bottom surface of the second rotating shaft.

[0008] Furthermore, the unmanned aerial vehicle body is rotatably connected to a lead screw, and two symmetrical positioning blocks are fixedly connected to the inner top wall of the unmanned aerial vehicle body. The outer surfaces of the two lead screws are rotatably connected to the interior of the positioning blocks, and bevel gears are fixedly connected to the ends of the two lead screws that are close to each other.

[0009] Furthermore, the first bevel gear and the second bevel gear mesh with each other, and the outer surfaces of the two lead screws are threaded with moving blocks. The bottom surfaces of the two moving blocks are fixedly connected with limit blocks, and the outer surfaces of the two limit blocks are slidably connected to the inside of the limit groove. The sides of the two moving blocks that are far apart from each other are fixedly connected with insert rods.

[0010] Furthermore, two symmetrical connecting blocks are fixedly connected to the upper surface of the square plate, and the outer surfaces of the two connecting blocks are inserted into the interior of the drone body, and the outer surfaces of the two insert rods are inserted into the interior of the connecting blocks.

[0011] Furthermore, the shock absorption mechanism includes a storage cavity, which is opened inside the support leg. A damper is fixedly connected to the inner top wall of the storage cavity. A slider is fixedly connected to the telescopic end of the damper. The outer surface of the slider is slidably connected to the inside of the storage cavity. A spring is fixedly connected to the upper surface of the slider.

[0012] Furthermore, the top end of the spring is fixedly connected to the inner top wall of the storage cavity, a support rod is fixedly connected to the bottom surface of the slider, the outer surface of the support rod is slidably connected to the inside of the support leg, and a base is fixedly connected to the bottom surface of the support rod.

[0013] Compared with existing technologies, this drone landing gear shock absorption device has the following advantages:

[0014] 1. By setting up an unmanned aerial vehicle (UAV) body and an installation mechanism, the landing gear and UAV body can be disassembled during actual use, thereby reducing the overall size of the UAV and making it easier to store and transport. This design effectively solves the problems existing in the current device.

[0015] 2. This utility model, by setting up a storage cavity, damper, slider, spring, support rod, and base, allows the drone to land. When the drone lands, gravity acts on the base, causing it to experience a downward impact force. Under the action of the impact force, the support rod pushes the slider upward, causing the slider to slide within the storage cavity. At this time, the damper begins to function, consuming some energy, while the spring is compressed, further absorbing and buffering the impact force. When the impact force disappears, the drone body returns to its original position under the elastic restoring force of the spring and the action of the damper, thereby achieving a shock absorption effect and protecting the drone's structure and internal components from damage.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] This embodiment provides a drone landing gear shock absorption device. By setting up the drone body 2 and the mounting mechanism 4, the landing gear and the drone body 2 can be separated in actual use with the help of the mounting mechanism 4, so as to reduce the overall size of the drone and make it easier to store and transport. This design effectively solves the problems existing in the existing devices.

[0024] Example 1

[0025] like Figure 1-5 As shown, the present invention proposes a drone landing gear shock absorption device, which includes a U-shaped plate 1, and a drone body 2 is provided above the U-shaped plate 1.

[0026] The drone body 2 also contains batteries and various necessary components to power the drone.

[0027] A set of support legs 3 is installed on the bottom surface of the square plate 1. The drone body 2 is equipped with an installation mechanism 4, which is used to connect the square plate 1 and the drone body 2. The support legs 3 are equipped with a shock absorption mechanism 5.

[0028] When the drone lands, the shock absorption mechanism 5 can effectively absorb and buffer the impact force generated during landing, protecting the drone's structure and internal components from damage.

[0029] A set of motors 6 are installed on the upper surface of the unmanned aerial vehicle body 2. The output end of the motors 6 is fixedly connected to a rotating shaft 7. A set of propeller blades 8 are fixedly connected to the outer surface of the rotating shaft 7.

[0030] Motor 6 provides power for the drone's flight. By driving the rotating shaft 7, motor 6 drives the propeller blades 8 to rotate, thereby generating lift and enabling the drone to fly in the air.

[0031] Example 2

[0032] like Figure 1-5 As shown, this embodiment further illustrates Example 1. The installation mechanism 4 includes a limiting groove 401, which is formed on the inner bottom wall of the unmanned aerial vehicle body 2. A second rotating shaft 402 is rotatably connected inside the unmanned aerial vehicle body 2. A rotating handle 403 is fixedly connected to the upper surface of the second rotating shaft 402, and a bevel gear 404 is fixedly connected to the bottom surface of the second rotating shaft 402.

[0033] The limiting groove 401 and the limiting block 409 work together to guide and limit the movement of the moving block 408, making the movement of the moving block 408 more stable and reliable. The surface of the rotating handle 403 is provided with a layer of non-slip and non-grip flexible rubber material.

[0034] The unmanned aerial vehicle body 2 is internally connected to a lead screw 406. The inner top wall of the unmanned aerial vehicle body 2 is fixedly connected to two symmetrical positioning blocks 405. The outer surfaces of the two lead screws 406 are rotatably connected to the interior of the positioning blocks 405. The two ends of the two lead screws 406 that are close to each other are fixedly connected to a bevel gear 407.

[0035] The first bevel gear 404 and the second bevel gear 407 mesh with each other. The outer surfaces of the two lead screws 406 are threaded with moving blocks 408. The bottom surfaces of the two moving blocks 408 are fixedly connected with limiting blocks 409. The outer surfaces of the two limiting blocks 409 are slidably connected to the inside of the limiting groove 401. The two moving blocks 408 are fixedly connected with insert rods 410 on the side of each other that are far apart from each other.

[0036] Two symmetrical connecting blocks 411 are fixedly connected to the upper surface of the UAV body 2. The outer surfaces of the two connecting blocks 411 are inserted into the interior of the UAV body 2, and the outer surfaces of the two insert rods 410 are inserted into the interior of the connecting blocks 411.

[0037] In actual use, rotating the handle 403 drives the second shaft 402 to rotate, which in turn drives the first bevel gear 404 to rotate. Under the meshing action of the first bevel gear 404 and the second bevel gear 407, the lead screw 406 rotates inside the drone body 2 and the positioning block 405. Under the transmission action of the lead screw 406, the two moving blocks 408 move towards each other, causing the limiting block 409 to move inside the limiting groove 401, and causing the insertion rod 410 to move until the insertion rod 410 is completely disengaged from the inside of the connecting block 411, thus releasing the limiting of the connecting block 411. Then, the return plate 1 is moved to remove the connecting block 411 from the drone body 2, thereby completing the disassembly of the landing gear and the drone body 2, so as to reduce the overall size of the drone and make it easier to store and transport. This design effectively solves the problems existing in the current device.

[0038] The shock absorption mechanism 5 includes a storage cavity 501, which is located inside the support leg 3. A damper 502 is fixedly connected to the inner top wall of the storage cavity 501. A slider 503 is fixedly connected to the telescopic end of the damper 502. The outer surface of the slider 503 is slidably connected to the inside of the storage cavity 501. A spring 504 is fixedly connected to the upper surface of the slider 503.

[0039] Upon landing, the damper 502 dissipates some energy, and the spring 504 is compressed, further absorbing and buffering the impact force. Through the combination of the two, a shock absorption effect can be achieved.

[0040] The top of the spring 504 is fixedly connected to the inner top wall of the storage cavity 501. The bottom surface of the slider 503 is fixedly connected to the support rod 505. The outer surface of the support rod 505 is slidably connected to the inside of the support leg 3. The bottom surface of the support rod 505 is fixedly connected to the base 506.

[0041] When the drone lands, gravity acts on the base 506, causing it to experience a downward impact force. Under the action of the impact force, the support rod 505 pushes the slider 503 upward, causing the slider 503 to slide within the receiving cavity 501. At this time, the damper 502 begins to function, consuming some energy. Simultaneously, the spring 504 is compressed, further absorbing and buffering the impact force. When the impact force disappears, the elastic restoring force of the spring 504 and the action of the damper 502 cause the drone body 2 to return to its original position, thereby achieving the effect of shock absorption and protecting the drone's structure and internal components from damage.

[0042] Working principle: In actual use, rotating the handle 403 drives the second shaft 402 to rotate, which in turn drives the first bevel gear 404 to rotate. Under the meshing action of the first bevel gear 404 and the second bevel gear 407, the lead screw 406 rotates inside the drone body 2 and the positioning block 405. Under the transmission action of the lead screw 406, the two moving blocks 408 move towards each other, causing the limiting block 409 to move inside the limiting groove 401, and causing the insertion rod 410 to move until the insertion rod 410 is completely disengaged from the inside of the connecting block 411, thus releasing the limiting of the connecting block 411. Then, the return plate 1 is moved to remove the connecting block 411 from the drone body 2, thereby completing the disassembly of the landing gear and the drone body 2, so as to reduce the overall size of the drone and make it easier to store and transport. This design effectively solves the problems existing in the current device. When the drone lands, gravity acts on the base 506, causing it to experience a downward impact force. Under the action of the impact force, the support rod 505 pushes the slider 503 upward, causing the slider 503 to slide within the receiving cavity 501. At this time, the damper 502 begins to function, consuming some energy. Simultaneously, the spring 504 is compressed, further absorbing and buffering the impact force. When the impact force disappears, the elastic restoring force of the spring 504 and the action of the damper 502 cause the drone body 2 to return to its original position, thereby achieving the effect of shock absorption and protecting the drone's structure and internal components from damage.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
