Description

Technical Field

[0001] The present invention relates to the technical field of drone auxiliary equipment, and in particular to an intelligent adjustment device for a low-altitude drone take-off and landing platform that can actively cooperate. Background Art

[0002] With the rapid development of drone technology, drones have found widespread application in a variety of fields, including agriculture, exploration, inspection, and logistics. However, drone takeoff and landing, especially at low altitudes, often present technical challenges. Traditional drone landing platforms are typically fixed structures that cannot dynamically adjust to the drone's tilt. This fixed platform presents numerous shortcomings when operating in complex environments.

[0003] First, when the take-off and landing platform is placed on uneven ground, it is difficult to ensure the platform's levelness. This can cause the drone to form a large angle with the platform during takeoff and landing, affecting the drone's balance and even causing the risk of landing failure or crash. Second, during landing, the drone may adopt a certain tilt due to crosswinds or other factors. If the take-off and landing platform does not match the drone's tilt, it will also increase landing instability and may even cause the drone to vibrate violently during landing, damaging the drone's structure or equipment.

[0004] Furthermore, traditional take-off and landing platforms also have shortcomings in securing and stabilizing drones after landing. If a drone is disturbed by external forces, it may slip or tip over, compromising its safety. Furthermore, existing take-off and landing platforms lack high positioning accuracy during landing and lack active coordination, making them incapable of achieving precise landings. This is particularly inadequate in scenarios requiring precise landings. Summary of the Invention

Through the configuration of a universal joint assembly and an adjustment mechanism, the platform plate can automatically adjust its own angle according to the different tilt postures of the drone during landing, achieving active parallelism with the drone. This design not only reduces the angle between the drone and the platform plate, but also improves the stability and safety of the drone during takeoff and landing, effectively avoiding the risk of landing failure or crash due to mismatch between the platform and the drone's posture. It also solves the problem of insufficient positioning accuracy during drone landing, lack of active coordination, and inability to achieve precise landing.

[0022] (3) Beneficial effects

[0023] Compared with the existing technology, the present invention provides an intelligent adjustment device for a low-altitude UAV take-off and landing platform that can actively cooperate, which has the following beneficial effects:

[0024] The present invention adopts the setting of the universal joint component, which not only facilitates the adjustment of the platform plate to different angles after installation, but also makes it easy for the platform plate to always be parallel to the ground when the equipment is located on uneven ground, thereby improving the take-off and landing of the drone on different grounds; through the setting of the adjustment mechanism, the angle of the platform plate can be adjusted according to the different tilt postures of the drone during the landing process, so that the platform plate is actively parallel to the drone body with different tilt postures, reducing the angle between the drone body and the platform plate, thereby realizing orderly landing.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example 1:

[0046] Refer to the attached Figures 1-11 An intelligent adjustment device for a low-altitude UAV take-off and landing platform that can actively cooperate includes a housing 1 and a cover plate 2 detachably mounted on the top of the housing 1. A mounting frame 4 is mounted inside the housing 1 via a lifting mechanism 3. A platform plate 5 is movably mounted on the top of the mounting frame 4 via a universal joint assembly 7. The platform plate 5 is used to support the take-off and landing of the UAV body 6.

[0047] The lifting mechanism 3 is provided to adjust the mounting frame 4 to a certain height, thereby facilitating the telescopic adjustment of the take-off and landing platform 5. This not only facilitates the protection of the drone body 6, but also forms a hidden protection work and a hidden take-off and landing work, thereby reducing the interference of crosswinds.

[0048] It should be noted that the lifting mechanism 3 utilizes a conventional mechanism for adjusting the height of the mounting frame 4, including but not limited to components such as a cylinder and a lead screw for adjusting the height. The drone body 6 utilizes a conventional low-altitude drone for agriculture, detection, testing, logistics, and distribution.

[0049] The universal assembly 7 is used to keep the platform plate 5 in a horizontal state when the housing 1 is located on different concave and convex surfaces;

[0050] The setting of the universal assembly 7 not only facilitates the adjustment of the platform plate 5 to different angles after installation, but also facilitates the platform plate 5 to always be parallel to the ground when the device is located on uneven ground, thereby improving the take-off and landing of the drone on different ground surfaces;

[0051] An adjustment mechanism 8 is provided on the top of the mounting frame 4. The adjustment mechanism 8 is used to adjust the angle of the platform plate 5 with the universal joint 7 according to the different tilt postures of the drone body 6, so that the platform plate 5 is parallel to the drone body 6;

[0052] By setting the adjustment mechanism 8, the angle of the platform plate 5 can be adjusted according to the different tilt postures of the drone during the landing process, so that the platform plate 5 is actively parallel to the drone body 6 with different tilt postures, reducing the angle between the drone body 6 and the platform plate 5, thereby achieving orderly landing. It not only has good angle adjustment, but also has the function of active coordination, thereby improving the stability of the drone during take-off and landing;

[0053] By configuring the universal joint 7 and adjustment mechanism 8, the platform automatically adjusts its angle based on the varying tilt of the drone during landing, achieving active parallelism with the drone. This design not only reduces the angle between the drone and the platform 5, but also improves the stability and safety of the drone during takeoff and landing, effectively avoiding the risk of landing failure or crashes caused by mismatched platform and drone attitudes.

[0054] Refer to the attached Figure 5 and Figure 7 , the interior of the drone body 6 and the top of the platform plate 5 are both equipped with a tilt sensor 51, and a wireless transmission system is provided between the drone body 6 and the interior of the housing 1;

[0055] By installing inclination sensors 51 inside the drone body 6 and on the top of the platform plate 5, the two inclination sensors 51 can detect the angles of the drone body 6 and the platform plate 5. When the drone body 6 is landing, the platform plate 5 is actively adjusted to be parallel to the drone body 6, thereby reducing the angle between the drone body 6 and the landing platform 5, thereby improving the orderliness and stability of the drone during landing.

[0056] The wireless transmission system is used to transmit the tilt posture of the drone body 6 to the control system inside the shell 1, and the adjustment mechanism 8 is activated by the control system to adjust the angle of the platform plate 5;

[0057] The tilting posture of the drone body 6 is transmitted through a wireless transmission system, and the platform plate 5 can be adaptively adjusted through the adjustment mechanism 8, so that the platform plate 5 and drones with different tilting postures can be processed in parallel, forming an active cooperative work, thereby improving the landing effect of the drone. This solves the problem that when the drone is landing, due to the drone being tilted at a certain angle or due to a certain angle caused by crosswind, there is a certain angle between the platform plate 5 and the drone during the landing process, thereby affecting the balance of the drone during landing, and ultimately causing damage due to strong vibration caused by imbalance.

[0058] Refer to the attached Figure 6-Figure 9 The universal assembly 7 includes an annular block 71 fixed to the top of the mounting frame 4 through a bracket, and a sphere 72 is movably connected to the inside of the annular block 71, and a control shaft 73 is fixedly connected to the inside of the sphere 72. The bottom end of the control shaft 73 is fixedly connected to a conical gravity block 74, and the top end of the control shaft 73 is fixed to the bottom of the platform plate 5;

[0059] By rolling the sphere 72 inside the annular block 71, the platform plate 5 connected to the sphere 72 via the control shaft 73 can be tilted at different angles. This not only facilitates parallel correction of the platform plate 5, but also facilitates adjustment of the platform plate 5 at different angles to adapt to different tilt postures of the drone, thus providing an active coordinated landing function.

[0060] By setting the conical gravity block 74, it is convenient to control the platform plate 5 through the control shaft 73. By vertically downwardly pointing the conical gravity block 74, the device can be placed on different ground surfaces, and its platform plate 5 is always in a vertical and parallel state, thereby improving the effect of its drone taking off and landing.

[0061] Refer to the attached Figure 9 The inside of the annular block 71 is fixedly connected to a clamping cylinder 75, and the telescopic end of the clamping cylinder 75 is fixedly connected to a clamping plate 76, which is used to frictionally lock the sphere 72 inside the annular block 71;

[0062] The clamping cylinder 75 is connected to the external power supply and control switch, and is used to drive the clamping plate 76 to extend and retract. The extension and retraction movement of the clamping plate 76 can frictionally lock the sphere 72 to ensure the stability of the sphere 72 inside the annular block 71. It not only ensures the stability of the platform plate 5 after self-parallel correction when the supporting ground is uneven, but also ensures the stability of the platform plate 5 after adjusting different angles through the adjustment mechanism 8. It solves the problem in the prior art that the landing platform plate 5 is prone to angle changes during the take-off and landing of the drone due to the lack of fastening work and the impact force during the take-off and landing of the drone, thereby affecting the normal take-off and landing of the drone.

[0063] Refer to the attached Figure 4 and Figure 7 The interior of the control shaft 73 is hollow, and a lifting cylinder 77 is fixedly connected to the interior of the control shaft 73. The telescopic end of the lifting cylinder 77 is fixedly connected to a matching shaft 78, and the top end of the matching shaft 78 extends to the top of the platform plate 5;

[0064] The lifting cylinder 77 is connected to the external power supply and control switch, and is used to drive the matching shaft 78 to move up and down. Through the upward movement of the matching shaft 78, it can cooperate with the UAV in the air, forming a subsequent orderly landing work, and improving the positioning and stability of the UAV during landing;

[0065] The bottom of the drone body 6 is fixedly connected to a matching frame 61, and the bottom of the matching frame 61 is fixedly connected to an annular cone sleeve 62. The matching shaft 78 is driven by the lifting cylinder 77 to be inserted into the inside of the annular cone sleeve 62 to form the positioning of the drone body 6 when landing;

[0066] By installing a matching frame 61 at the bottom of the drone body 6, and fixing the bottom of the matching frame 61 with an annular cone sleeve 62, when the matching shaft 78 is lifted upward, the matching shaft 78 is inserted into the inside of the annular cone sleeve 62 to form a fixed work, thereby preventing the drone from shaking and swaying due to side wind or other reasons during landing, and causing landing difficulties. The drone has the function of actively cooperating with landing.

[0067] Refer to the attached Figure 4 and Figure 7 , an annular magnet block 79 is provided on the top of the platform plate 5, and the annular magnet block 79 is slidably sleeved on the outer surface of the matching shaft 78, and the annular cone sleeve 62 is made of a metal material that can be magnetically attracted by the annular magnet block 79; the outer surfaces of the top and bottom of the matching shaft 78 are both provided with limited skirts;

[0068] The lower skirt is provided so that when the mating shaft 78 is removed from the interior of the control shaft 73, the annular magnet block 79 can be driven to lift up, thereby facilitating high-strength adsorption of the annular cone sleeve 62 by the annular magnet block 79, thereby ensuring the stability of the drone body 6 and preventing the drone from falling off and contacting the mating shaft 78, causing subsequent rollover problems.

[0069] The upper skirt is provided so that when the mating shaft 78 is retracted downwards by a certain distance, the upper skirt can come into contact with the annular magnet block 79. By continuously retracting the mating shaft 78, the drone can be driven to land stably above the platform plate 5. Finally, by continuously retracting the mating shaft 78, the annular magnet block 79 can be peeled off from the bottom of the drone. This not only prevents the presence of the annular magnet block 79 from affecting the drone's next take-off, but also improves the stability and orderliness of the drone during landing.

[0070] A magnet sheet 52 is embedded in the top of the platform plate 5, and a metal pad 63 is fixedly connected to the landing frame of the drone body 6;

[0071] By installing a magnet sheet 52 on the top of the platform plate 5 and connecting a metal pad 63 to the landing frame of the drone body 6, when the drone lands on the platform plate 5, the magnet sheet 52 adsorbs the metal pad 63, thereby ensuring the stability of the drone after landing;

[0072] It should be noted here that the magnet piece 52 is in a ring shape, which facilitates better magnetic adsorption of the metal pads 63 located at different positions to form stability after the drone is seated.

[0073] Refer to the attached Figure 4 and Figure 7 , an infrared transmitter 64 is embedded in the top of the control shaft 73, and an infrared receiver 65 is fixedly connected to the bottom of the matching frame 61;

[0074] The infrared emitter 64 is used to emit an infrared beam, which is received by the infrared receiver 65, thereby facilitating the better insertion of the shaft 78 into the annular cone sleeve 62, thereby achieving the landing calibration of the UAV and enhancing its positioning during landing;

[0075] The specific operating principle is that the UAV is controlled by a remote control to fly on the top of the platform plate 5, and the infrared light beam is received by the infrared receiver 65. When the infrared light beam is received, it means that the UAV is directly above the landing point, and then it is convenient to insert the matching shaft 78 into the interior of the annular cone sleeve 62 to form an orderly landing of the UAV.

[0076] Refer to the attached Figure 8 and Figure 11 The adjustment mechanism 8 includes a lifting member for lifting the side of the platform plate 5 and an adjusting member for annularly adjusting the lifting member;

[0077] The jacking member in the adjustment mechanism 8 is provided to lift the side of the platform plate 5, so that the platform plate 5 is tilted at an angle by the universal assembly 7, thereby facilitating the platform plate 5 to better adapt to the landing of drones with different inclination angles. The adjustment member is provided to adjust the position of the jacking member, thereby meeting the adjustment of different azimuth angles of the platform plate 5 and improving the diversity of inclination adjustment.

[0078] What is required here is that the lifting member and the adjusting member both adopt the electric telescopic rod, motor, etc. in the prior art to automatically adjust the angle of the platform plate 5.

[0079] Example 2: Based on Example 1, the difference is that;

[0080] Refer to the attached Figure 6 and Figure 10 The bottom of the mounting frame 4 is provided with a reinforcement assembly 9 for reinforcing the platform plate 5. The reinforcement assembly 9 includes a fastening cylinder 91 fixed to the bottom of the mounting frame 4 through a bracket. At least two fastening ropes 92 are movably passed through the interior of the fastening cylinder 91. Both ends of the at least two fastening ropes 92 are fixed to the bottom of the platform plate 5. The bottom of the mounting frame 4 is fixedly connected to a plurality of guide sleeves 93 for guiding the at least two fastening ropes 92.

[0081] The at least two fastening ropes 92 are provided to further reinforce the platform plate 5, thereby ensuring the stability of the platform plate 5 after angle adjustment or parallel adjustment, and improving the impact resistance of the platform plate 5;

[0082] It should be noted that at least two fastening ropes 92 are arranged in an equidistant and encircling manner, and the number of fastening ropes 92 can be set according to actual conditions. The more fastening ropes 92 there are, the higher the stability is guaranteed.

[0083] The bottom of the mounting frame 4 is fixedly connected to a reinforcement cylinder 94, and the telescopic end of the reinforcement cylinder 94 is fixedly connected to a reinforcement block 95;

[0084] The reinforcement cylinder 94 is a telescopic cylinder in the prior art, which is connected to an external power supply and a control switch, and is used to drive the reinforcement block 95 to move up and down. The downward movement of the reinforcement block 95 can tighten the at least two superimposed fastening ropes 92, thereby facilitating the reinforcement of the periphery of the platform plate 5 through the two fastened fastening ropes 92, further ensuring the stability of the platform plate 5 after the angle adjustment;

[0085] The problem that the platform plate 5 is supported solely by the universal joint 7 and has low stability is solved, so that when the impact force is large when the drone lands, the impact force is likely to cause a high-intensity impact on the platform plate 5, causing the platform plate 5 to tilt, resulting in a change in the balance of the drone and a crash.

[0086] Example 3: Based on Example 1, the difference is that;

[0087] Refer to the attached Figure 11 The adjusting member includes an annular gear disc 81 fixed to the top of the mounting frame 4 and a sliding frame 82 slidably connected to the top of the mounting frame 4. The top of the sliding frame 82 is fixedly connected to a rotating shaft 83 that is rotatably connected. The rotating shaft 83 is fixedly connected to a gear 84 that meshes with the outer surface of the annular gear disc 81 through a one-way bearing. The top of the sliding frame 82 is fixedly connected to a motor 85 for rotating the rotating shaft 83.

[0088] The motor 85 is connected to the external power supply and control system. It is a forward and reverse rotating and speed-adjustable electric motor. It is set up using the connection method and encoding method of the existing technology and is used to drive the rotating shaft 83 to rotate forward and reverse. The clockwise rotation of the rotating shaft 83 can drive the gear 84 to rotate through the one-way bearing. The gear 84 is engaged with the outer surface of the annular gear plate 81, so that the overall position of the lifting member can be adjusted, thereby meeting the lifting movement at different positions and forming the adjustment work of different angles of the platform plate 5.

[0089] The lifting member includes a screw rod 86 rotatably connected to the sliding frame 82. The screw rod 86 is threadedly connected to a threaded block 87, and the top of the threaded block 87 is fixedly connected to a lifting rod 88. The threaded block 87 is slidably connected to the top of the sliding frame 82 through a guide rod. The bottom end of the screw rod 86 is transmission-connected to the rotating shaft 83 through a belt set 89.

[0090] The screw rod 86 is connected to the rotating shaft 83 through a belt group 89, and the gear 84 is connected to the rotating shaft 83 through a one-way bearing. When the rotating shaft 83 rotates counterclockwise, the screw rod 86 can be driven to rotate alone, thereby forming an upward movement of the threaded block 87 and the lifting rod 88, thereby adjusting the angle of the platform plate 5. When the rotating shaft 83 rotates clockwise, it can not only drive the lifting member to perform position conversion, forming a lifting movement of different angles, but also synchronously drive the lifting member to perform a retraction movement, thereby improving the smoothness of the position conversion of the lifting member and enhancing the convenience of subsequent lifting adjustment.

[0091] The guide rod is provided to improve the smoothness of the up and down movement of the threaded block 87;

[0092] Among them, one of the pulleys of the belt set 89 is connected to the screw rod 86 using an elastic clamping sleeve 810;

[0093] It should be noted here that the elastic clamping sleeve 810 is composed of a rigid sleeve and an elastic sleeve. By fixing the elastic sleeve inside the rigid sleeve, the rigid sleeve is clamped and connected to the bottom end of the screw rod 86 in an elastic clamping manner, and the pulley of the belt group 89 is fixedly connected to the outer surface of the rigid sleeve, so that when the gear 84 is driven to rotate clockwise by the motor 85, the screw rod 86 can be driven to rotate synchronously through the belt group 89 to form a descending movement of the threaded block 87. When the threaded block 87 moves downward to the extreme position, when the gear 84 continues to rotate, the screw rod 86 will not be driven to rotate continuously through the belt group 89, thereby preventing motion interference in the lifting adjustment and position adjustment.

[0094] The specific principle is that when the elastic clamping sleeve 810 is driven to rotate by the belt group 89, the elastic clamping sleeve 810 clamps the screw rod 86, causing the screw rod 86 to rotate synchronously. When the threaded block 87 moves downward or upward to the extreme position, the elastic clamping sleeve 810 is in an idling state, which can effectively prevent the problem of motion interference.

[0095] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
