Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) carriers, and in particular to a UAV transport vehicle and its UAV take-off and landing device. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly being used in aerial photography, inspection, surveying, and emergency rescue. To facilitate the take-off, landing, and storage of drones, various drone take-off and landing devices have emerged.

[0003] Existing drone takeoff and landing systems typically include a fixed-size landing platform mounted on a chassis for vertical takeoff, landing, and parking of the drone. This platform is usually only slightly larger than the drone's overall dimensions to meet basic parking requirements, resulting in a relatively narrow overall width. When a drone takes off or lands on this narrow platform, the airflow generated by its high-speed rotor rotation creates strong edge turbulence near the platform's edge. This turbulence not only reduces the drone's flight stability but can also cause attitude fluctuations, and in severe cases, even lead to takeoff / landing failure or collisions. Utility Model Content

[0004] Therefore, it is necessary to provide a drone transport vehicle and its drone take-off and landing device to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, the inventors provide a drone take-off and landing device, including a take-off and landing platform. The take-off and landing platform includes a take-off and landing plate and two tilting plates. The take-off and landing plate is used for parking the drone. The two tilting plates are located on the left and right sides of the take-off and landing plate. The tilting plates are hinged to the take-off and landing plate and can rotate relative to the take-off and landing plate.

[0006] Furthermore, it also includes a tilting mechanism for driving the tilting plate to rotate relative to the lifting plate.

[0007] Furthermore, the flipping mechanism includes two sets of flipping units, each set of flipping units corresponding to a flipping plate. Each set of flipping units includes a flipping telescopic rod, one end of which is hinged to the lifting plate, and the other end of which is hinged to the flipping plate. The flipping telescopic rod is used to drive the flipping plate to rotate relative to the lifting plate.

[0008] Furthermore, the tilting telescopic rod is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator.

[0009] Furthermore, it also includes a sliding mechanism for driving the lifting plate to slide.

[0010] Furthermore, the sliding mechanism includes two side-by-side slide rails and a sliding telescopic rod. The slide rails are pulley-type slide rails, including a first rail body and a second rail body. The first rail body and the second rail body are slidably connected by pulleys. The second rail body or the first rail body is disposed on the lifting plate. The sliding telescopic rod is connected to the lifting plate and is used to drive the lifting plate to slide along the slide rails.

[0011] Furthermore, the slide rail also includes a connector, the pulley includes a first pulley and a second pulley, the first rail body is provided with a groove, the connector is disposed on the second rail body and supports the first pulley and the second pulley, the first pulley is used to slide in connection with the upper wall of the groove, the second pulley is used to slide in connection with the side wall of the groove, the connector is provided with a first receiving cavity, and the second pulley is disposed in the first receiving cavity.

[0012] Furthermore, the sliding telescopic rod is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator.

[0013] Furthermore, it also includes two limiting structures, one of which corresponds to one of the flip plates, and the limiting structures are used to limit the flip plate on the external positioning member.

[0014] Furthermore, the external positioning element is provided with a positioning hole, and the limiting structure includes two oppositely arranged connecting plates and a pin. The two oppositely arranged connecting plates are for the pin to be inserted, and the pin is used to be inserted into the positioning hole of the positioning element.

[0015] To achieve the above objectives, the inventors provide a drone transport vehicle, including a chassis, a cargo box, and a drone take-off and landing device. The chassis supports the cargo box, and the cargo box supports the drone take-off and landing device, which is the drone take-off and landing device described in the above embodiments.

[0016] The carriage includes a floor, a left side panel, and a right side panel. Both the left side panel and the right side panel can rotate relative to the floor. Each of the left side panel and the right side panel is provided with a positioning element. One flip plate corresponds to one positioning element. Both flip plates are provided with slots for the positioning elements to pass through. In a limiting structure, the slots are located between two oppositely arranged connecting plates.

[0017] The rear portion of the lifting platform is movable to the rear of the carriage.

[0018] To achieve the above objectives, the inventors provide a drone transport vehicle, including a chassis and a drone take-off and landing device. The chassis supports the drone take-off and landing device, which is the drone take-off and landing device described in any of the above embodiments. The rear part of the take-off and landing plate can be moved to the rear of the chassis.

[0019] Unlike existing technologies, the above technical solution has the following beneficial effects.

[0020] When the drone needs to take off or land, the side flaps unfold downwards, significantly increasing the effective width of the takeoff and landing platform. This greatly reduces the generation of edge vortices and turbulence, improving the aerodynamic stability of the drone during takeoff and landing and reducing the risk of attitude loss of control. When not in operation, the flaps can be folded up and erected, or stacked on the takeoff and landing platform, reducing the width of the platform and making it more compact.

[0046] Please see Figures 1 to 7 This embodiment provides a drone take-off and landing device, including a take-off and landing platform 2. The take-off and landing platform 2 includes a take-off and landing plate 21 and two flip plates 22. The take-off and landing plate 21 is used for the drone to park. The two flip plates 22 are located on the left and right sides of the take-off and landing plate 21. The flip plates 22 are hinged to the take-off and landing plate 21 and can rotate relative to the take-off and landing plate 21.

[0047] Typically, two tilting plates 22 are symmetrically arranged on the left and right sides of the lifting platform 21. The two tilting plates 22 are respectively mounted on the left and right sides of the lifting platform 21 via a hinged structure, and can rotate upwards or downwards relative to the lifting platform 21 around a horizontal axis. If the lifting platform 21 and the tilting plates 22 are rectangular, the lifting platform 2 will have a convex shape after the two tilting plates 22 are unfolded. The rotation of the tilting plates 22 can be achieved manually or controlled by a powered tilting unit.

[0048] When the drone needs to take off or land, the two side flip panels 22 are unfolded downwards, significantly increasing the effective width of the takeoff and landing platform 2. This greatly reduces the generation of edge vortices and turbulence, improves the aerodynamic stability of the drone during takeoff and landing, and reduces the risk of attitude loss of control. When not in operation, the flip panels 22 can be folded up and erected, or stacked on the takeoff and landing plate 21, reducing the width of the takeoff and landing platform 2 and making it more compact.

[0049] Please see Figure 6 In some embodiments, the UAV take-off and landing device further includes a flipping mechanism 3, which drives the flipping plate 22 to rotate relative to the landing plate 21. The flipping mechanism 3 is powered and can control the unfolding and retraction of the flipping plate 22 after receiving instructions from the operator, thus achieving automation and intelligence.

[0050] Please see Figure 6 In some embodiments, the flipping mechanism 3 includes two sets of flipping units, each set corresponding to a flipping plate 22. Each set of flipping units includes a flipping telescopic rod 31, one end of which is hinged to the lifting plate 21, and the other end of which is hinged to the flipping plate 22. The flipping telescopic rod 31 is used to drive the flipping plate 22 to rotate relative to the lifting plate 21. The flipping telescopic rod 31 is an actively extendable linear motion component. One end of it is hinged to the lifting plate 21 via a hinge seat, and the other end is hinged to the flipping plate 22 via another hinge seat, forming a three-point hinge structure. When the flipping telescopic rod 31 extends, its thrust acts on the flipping plate 22, pushing the flipping plate 22 to rotate downward around the main hinge axis between it and the lifting plate 21 until the flipping plate 22 reaches a horizontal working position. When the flipping telescopic rod 31 retracts, it pulls the flipping plate 22 upward to flip, realizing the retraction action.

[0051] Please see Figure 6In a further embodiment, the tilting telescopic rod 31 is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. The hydraulic cylinder is supplied with pressurized oil by a hydraulic pump station, and the extension and retraction of the piston rod are controlled by a solenoid directional valve. The pneumatic cylinder uses compressed air as a power source, and the airflow direction is controlled by a solenoid valve to drive the extension and retraction of the piston rod. The electric actuator integrates a DC motor, a reduction gearbox, and a lead screw / nut transmission mechanism. The rotation of the motor drives the lead screw, thereby achieving smooth extension and retraction of the actuator.

[0052] The tilting telescopic rod 31 is electrically connected to the control system, enabling automated and intelligent control of its movements. For hydraulic or pneumatic cylinders, the tilting telescopic rod 31 itself is not directly energized, but its movement is controlled by a solenoid valve. The solenoid valve coil is electrically connected to the control system, which controls the solenoid valve's reversal via a switching signal, thereby determining the flow direction of hydraulic oil or compressed air and driving the piston rod of the hydraulic / pneumatic cylinder to extend or retract. For electric actuators, the actuator is connected to the signal port of the control system via a wire to receive control signals.

[0053] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the drone take-off and landing device further includes a sliding mechanism 1, which drives the landing plate 21 to slide. The sliding mechanism 1 may be powered and can control the sliding of the landing plate 21 after receiving instructions from the operator, realizing the conversion between the landing plate 21 in the storage state and the working state, such as pushing the landing plate 21 from inside the chassis 5 to the outside, or retracting it from the outside back into the chassis 5 to complete storage, thereby achieving automation and intelligence.

[0054] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the sliding mechanism 1 includes two side-by-side slide rails 11 and a sliding telescopic rod 12. The slide rails 11 are pulley-type slide rails 11, including a first rail body 111 and a second rail body 112. The first rail body 111 and the second rail body 112 are slidably connected by pulleys. The second rail body 112 or the first rail body 111 is provided on the lifting plate 21. The sliding telescopic rod 12 is connected to the lifting plate 21 and is used to drive the lifting plate 21 to slide along the slide rails 11.

[0055] The first rail 111 and the second rail 112 can be elongated strips extending in the front-to-back direction. The two rails 11 can form a double-sided support structure to ensure that the lifting plate 21 is subjected to balanced forces during sliding. There are two installation methods for the second rail 112 or the first rail 111: the first is that the two second rails 112 are installed on the chassis 5 of the transport vehicle, and the two first rails 111 are installed on the lifting plate 21; the second is that the two first rails 111 are installed on the chassis 5 of the transport vehicle, and the two second rails 112 are installed on the lifting plate 21.

[0056] The sliding telescopic rod 12 is a linear motion component that can be actively extended and retracted. One end of it is hinged to the lifting plate 21 through a connecting seat, and the other end is connected to the chassis 5 through another connecting seat. The sliding telescopic rod 12 is arranged along the sliding direction of the lifting plate 21, and the lifting plate 21 slides along the slide rail 11 as the sliding telescopic rod 12 extends and shortens.

[0057] Please see Figures 2 to 5 In some embodiments, the slide rail 11 further includes a connector 113, and the pulleys include a first pulley 114 and a second pulley 115. The first rail body 111 is provided with a groove 117, and the connector 113 is disposed on the second rail body 112 and supports the first pulley 114 and the second pulley 115. The first pulley 114 is used to contact the upper wall of the groove 117 (e.g., Figure 5 (as indicated by arrow s) slidably connected, the second pulley 115 is used to slide against the side wall of the groove 117 (such as...) Figure 5 (The position indicated by arrow c) is slidably connected, and the connector 113 has a first receiving cavity 118 inside, and the second pulley 115 is located in the first receiving cavity 118.

[0058] The pulleys rotate as the lifting plate 21 moves. The second pulley 115 on the left slide rail 11 of the lifting plate 21 is slidably connected to the left slide groove 117, and the second pulley 115 on the right slide rail 11 of the lifting plate 21 is slidably connected to the right slide groove 117. This significantly reduces motion resistance and improves the smoothness of the sliding of the lifting plate 21.

[0059] Figure 5 As shown, the second pulley 115 has an axial direction of vertical movement and protrudes from the first receiving cavity 118. The first pulley 114 has an axial direction of horizontal movement and is located outside the second pulley 115. When the lifting plate 21 moves from front to back under the push of the sliding telescopic rod 12, both the first pulley 114 and the second pulley 115 rotate with the movement of the lifting plate 21, achieving low-resistance sliding. Although the first pulley 114 and the second pulley 115 are mounted on the same connecting member 113, their structures may differ. The second pulley 115 has a housing 116, and the wheel body of the second pulley 115 is disposed on the housing 116 and can rotate relative to the housing 116. The housing 116 is fitted into the first receiving cavity. The wheel body of the first pulley 114 can be mounted on the outer wall of the connecting member 113 via bearings and can rotate around the connecting member 113.

[0060] Under normal operating conditions, the first pulley 114 primarily contacts the upper wall of the slide groove 117 and rolls forward on it. At this time, the first pulley 114 acts as the main supporting element, bearing the weight of the lifting plate 21, and achieves low-resistance horizontal sliding through rolling friction. By precisely controlling the height of the slide groove 117, an appropriate gap can be reserved in the assembled state, allowing the first pulley 114 to contact both the upper and lower walls of the slide groove 117 during normal operation.

[0061] When the lifting plate 21 tends to shift left or right during sliding due to uneven force, guide rail installation errors, or external disturbances, the side wall of the slide groove 117 will gradually approach and eventually contact the second pulley 115. At this time, a sliding friction contact is formed between the second pulley 115 and the side wall of the slide groove 117, generating a reverse constraint force to prevent the lifting plate 21 from continuing to shift, thereby ensuring its smooth operation along the predetermined trajectory.

[0062] In some other embodiments, only the first pulley 114 is needed, and the second pulley 115 is not required.

[0063] It should be noted that the sliding mechanism 1 is not limited to the pulley type slide rail 11 mentioned above. Other types of sliding mechanisms can also be used, such as ball type slide rail, slider type slide rail or synchronous belt drive type sliding mechanism, all of which can achieve smooth sliding and reliable guidance of the lifting plate 21.

[0064] In some embodiments, the sliding telescopic rod 12 is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. The sliding telescopic rod 12 can be electrically connected to the control system to achieve automated and intelligent control of the action.

[0065] Please see Figure 7 In some embodiments, the drone take-off and landing device further includes two limiting structures 4, each limiting structure 4 corresponding to one flip plate 22. The limiting structure 4 is used to limit the flip plate 22 to the external positioning member 43. The limiting structure 4 can lock the flip plate 22 to the positioning member 43, preventing the flip plate 22 from shaking in the unfolded or retracted state and affecting the operation.

[0066] Please see Figure 7In some embodiments, the external positioning member 43 is provided with a positioning hole 431, and the limiting structure 4 includes two oppositely arranged connecting plates 41 and a pin 42. The two oppositely arranged connecting plates 41 are for the pin 42 to be inserted, and the pin 42 is used to insert into the positioning hole 431 of the positioning member 43. The flip plate 22 is flipped to a preset position, which can be the fully unfolded position of the flip plate 22 in the working state or the fully retracted position in the stored state. At this time, the positioning hole 431 of the positioning member 43 and the insertion hole of the connecting plate 41 are aligned, allowing the pin 42 to be inserted into the positioning hole 431 of the positioning member 43 and the insertion hole of the connecting plate 41, thereby achieving rigid locking and limiting of the flip plate 22. The unlocking process is simple and convenient; simply removing the pin 42 will release the restriction on the flip plate 22.

[0067] In some embodiments, the flip plate 22 is provided with a slot 221 through which the positioning member 43 passes, providing clearance space for the positioning member 43. In a limiting structure 4, the slot 221 is located between two oppositely arranged connecting plates 41.

[0068] In other embodiments, the limiting structure 4 is not limited to the above-mentioned pin-type limiting structure 4, but may also adopt other forms of limiting structure, such as magnetic limiting structure, rope-type limiting structure, buckle-type limiting structure, etc.

[0069] In a preferred embodiment, when the two flip plates are rotated and laid flat, the overall width d of the two flip plates is ≥ 0.7D, where D is the diameter of the circular area when the UAV rotor rotates. Figure 3 In this system, drones are typically placed one in front of the other, with the front of the drone facing the front of the transport vehicle and the rear of the drone facing the rear of the transport vehicle. The overall width of the two flip-up panels is along the width of the transport vehicle, and by controlling d≥0.7D, the generation of edge eddies and turbulence can be reduced as much as possible.

[0070] Please see Figure 2 This embodiment provides a drone transport vehicle, including a chassis 5, a cargo box 6, and a drone take-off and landing device. The chassis 5 supports the cargo box 6, and the cargo box 6 supports the drone take-off and landing device. The drone take-off and landing device is any of the drone take-off and landing devices described in the above embodiments.

[0071] Please see Figure 7 In some embodiments, the carriage 6 is equipped with a positioning element 43, and the rear portion of the lifting platform 21 is movable to the rear of the carriage 6. The carriage 6 includes a floor plate 61, a left side plate 62, and a right side plate 63. Both the left side plate 62 and the right side plate 63 can rotate relative to the floor plate 61. Each of the left side plate 62 and the right side plate 63 is equipped with a positioning element 43, and one tilting plate 22 corresponds to one positioning element 43. Figure 7The positioning element 43 on the left side plate 62 is shown. Both flip plates 22 are provided with slots 221 for the positioning element 43 to pass through. In a limiting structure 4, the slots 221 are located between two oppositely arranged connecting plates 41.

[0072] The chassis 5 possesses full driving capability, outputting power through a power mechanism to drive the running gear, enabling the transport vehicle to move. In most embodiments, a wheeled chassis 5 is used, offering good road adaptability and driving stability; the power source can be an engine, an electric motor, or a hybrid power system, supporting long-term field operations. The cargo box 6 is a foldable cargo box 6, with the left side panel 62 and right side panel 63 rotatably connected to the left and right sides of the base plate 61 via hinge shafts. When unfolded, the left side panel 62 and right side panel 63 form an open space.

[0073] Please see Figure 2 In operation, the left side panel 62 and right side panel 63 are first unfolded to a horizontal position. Then, the lifting plate 21 is moved out along the rear of the vehicle via the sliding mechanism 1. The rear part of the lifting plate 21 moves to the rear of the carriage 6, and the flip-up panels 22 on both sides of the lifting plate 21 are unfolded to the preset positions. The flip-up panels 22 cover the space below the flip-up panels 22 at the rear of the carriage 6, reducing turbulence interference. When the flip-up panels 22 are in the preset positions, the flip-up door on the left side rotates to the top of the left side panel 62, and the flip-up door on the right side rotates to the top of the right side panel 63. The positioning hole 431 of the positioning member 43 and the insertion hole of the connecting plate 41 are aligned, allowing the pin 42 to be inserted into the positioning hole 431 of the positioning member 43 and the insertion hole of the connecting plate 41, thereby achieving rigid locking and limiting of the flip-up panels 22.

[0074] In the stowed state, the two flip plates 22 rotate upward to the upright position, and the left plate 62 and the right plate 63 also rotate upward to the upright position. The positioning hole 431 of the positioning component 43 and the insertion hole of the connecting plate 41 are aligned, so that the pin 42 is inserted into the positioning hole 431 of the positioning component 43 and the insertion hole of the connecting plate 41, thereby achieving rigid locking and limiting of the flip plate 22.

[0075] Preferably, the left side panel 62 and the right side panel 63 can both cooperate with the limiting structure 4 of the flip panel 22 in the stored or unfolded state.

[0076] The sliding mechanism 1 described above is horizontally placed, meaning the lifting plate 21 slides horizontally, preferably in the front-to-rear direction of the transport vehicle (from the front to the rear). In some other embodiments, the sliding mechanism 1 can also be vertically arranged, allowing the lifting plate 21 to slide vertically, i.e., raising or lowering the lifting plate 21. When the lifting plate 21 is raised, its lower part is farther from the chassis 5, which can also lead to the formation of turbulence.

[0077] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
