Description

Technical Field

[0001] This utility model relates to a chassis for a drone transport vehicle, belonging to the field of chassis technology. Background Technology

[0002] With the widespread application of drones in emergency rescue, logistics delivery, and military reconnaissance, there is an urgent need for efficient and reliable mobile deployment platforms to shorten mission response time. These transport vehicles must be able to quickly load and unload drones in complex environments, ensuring equipment safety and improving operational continuity, and are particularly suitable for rapid switching in multi-mission scenarios and field operations.

[0003] Existing transportation equipment mostly adopts a fixed container design and relies on manual loading and unloading mechanisms, resulting in low loading and unloading efficiency and susceptibility to the experience of operators. At the same time, it lacks vertical-horizontal coordinated motion control capabilities, which can easily cause drones to collide with the container during the movement out / in process, resulting in structural damage or mission delays. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a chassis for a drone transport vehicle to solve the problems of the existing technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A chassis for a drone transport vehicle includes: a transport compartment mounted on a transport chassis for accommodating drones;

[0007] A detachable connection mechanism is provided on the transport chassis to enable a detachable connection between the transport compartment and the transport chassis.

[0008] A carrying and moving mechanism is disposed inside the transport compartment and is used to move the drone from the transport compartment to the outside;

[0009] The control module is connected to the carrier-moving mechanism and is used to control the carrier-moving mechanism to automatically perform an out-of-cabin operation to move the UAV from the transport container to the outside, or to perform an in-cabin operation to move the UAV from the outside into the transport container.

[0010] The carrier-mounted mobile mechanism has the function of enabling the UAV to move in the vertical and horizontal directions, and the control module has the function of controlling the carrier-mounted mobile mechanism to perform vertical and horizontal movements in a predetermined sequence.

[0011] As a further improvement, the detachable connection mechanism includes a support column fixedly installed above the transport chassis and a pull arm hook installed above the support column. The bottom of the pull arm hook is fixedly installed on the transport chassis. A locking sleeve is provided on one side of the transport compartment. The transport compartment cooperates with the pull arm hook through the locking sleeve to realize the detachable connection between the transport compartment and the transport chassis.

[0012] As a further improvement, a set of guide grooves is provided on the inner side of the transport compartment.

[0013] The gear and rack mechanism includes a support frame, which includes a guide rail slidably mounted in the guide groove and a crossbar integrally disposed on the side of the guide rail. A rack is disposed below the crossbar, and a gear meshes below the rack. The gear is driven by a first motor installed in the transport compartment.

[0014] As a further improvement, the support frame also includes a plurality of protrusions integrally disposed on the outside of the crossbar;

[0015] The lifting assembly includes a telescopic rod fixedly installed below the protrusion and a third motor disposed inside the transport compartment. The telescopic rod is driven by the third motor, which is electrically connected to the control module. The telescopic rod is fixedly connected to the side of the support platform. The control module, in cooperation with the third motor, controls the telescopic rod to drive the support platform to rise / fall.

[0016] As a further improvement, a landing frame is provided below the drone, and a positioning groove is provided on the upper surface of the landing frame;

[0017] A first gravity sensing component is installed above the support platform, a second gravity sensing component is installed below the support platform, and a third gravity sensing component is installed inside the transport compartment corresponding to the support platform. The control module is electrically connected to the first gravity sensing component, the second gravity sensing component, the third gravity sensing component, and the locking component.

[0018] When the landing frame is placed on the support platform, the gravity of the drone activates the first gravity sensing component, and the locking component is controlled by the control module to fix the landing frame to the support platform.

[0019] When the drone is inside the transport container, the support platform contacts the transport chassis, and the second gravity sensing component and the third gravity sensing component are activated to keep the locking component in a locked state.

[0020] When the drone leaves the cabin, it moves the support platform vertically upward via the lifting assembly, while simultaneously releasing the second and third gravity sensing assemblies and keeping the locking assembly in a locked state.

[0021] The drone and support platform are moved laterally to the outside of the transport container by the translation component, and the support platform on which the drone is placed is lowered to the ground by the lifting component. The second gravity sensing component is activated when it comes into contact with the ground, and the locking component is released from the constraint of the landing frame.

[0022] The drone enters the warehouse and lands on the support platform. It contacts and activates the first gravity sensor component, and the lifting component lifts the support platform vertically upward. At the same time, the second gravity sensor component is deactivated. The control module controls the locking component to fix the landing frame on the support platform.

[0023] The drone and support platform are moved laterally into the transport container by the translation component, and the support platform holding the drone is lowered to the bottom of the transport container by the lifting component, while the second gravity sensing component and the third gravity sensing component are activated simultaneously.

[0024] As a further improvement, the support platform is provided with several sets of locking components corresponding to the landing frame position, which are used to stably fix the drone on the support platform during movement;

[0025] The locking assembly includes several sets of locking rods rotatably mounted on the support platform and a second motor that drives the locking rods to rotate. Two locking rods in the same set are arranged opposite each other and staggered. The ends of the locking rods are bent inward to form arc-shaped hooks. The second motor is electrically connected to the control module. The control module cooperates with the second motor to control the rotation of the locking rods, causing the arc-shaped hooks to insert into / disengage from the positioning groove.

[0026] As a further improvement, a power conduction component is also included. The power conduction component includes a first conductive terminal disposed inside the positioning groove and a second conductive terminal disposed inside the arc-shaped hook portion. When the third gravity sensing component is activated, the control module, in cooperation with the first and second conductive terminals, charges the battery inside the drone.

[0027] As a further improvement, the control module includes a wireless remote controller and a limit switch. The wireless remote controller is equipped with a one-button exit button and a one-button entry button. The limit switch is installed at the extreme movement position of the supporting moving mechanism and is used to provide a position signal to the control module.

[0028] The control module also includes a detection sensor component installed inside the transport compartment near the rear door. When the one-button exit operation is performed, the detection sensor component monitors whether the rear double doors of the transport compartment are open normally. If they are open normally, the load-bearing moving mechanism is controlled to first perform a vertical upward movement, then a horizontal extension movement, and finally a vertical downward movement until the support platform reaches the ground.

[0029] As a further improvement, the pull arm hook includes a short rod and a long rod extending obliquely upwards and to both sides from the top of the connecting column. The end of the long rod is bent toward the side of the short rod to form a limiting part. A limiting rod is rotatably installed at the end of the short rod. The side of the limiting rod away from the long rod is connected to the short rod by a limiting spring. The top extreme position of the limiting rod abuts against the inside of the limiting part. The short rod, the long rod, the limiting part, and the limiting rod form an openable and closable locking cavity. The locking cavity is opened by adjusting the limiting rod to rotate and the locking sleeve is placed into it. Then, the limiting spring resets the limiting rod to close the locking cavity and limit the locking sleeve.

[0030] Beneficial effects:

[0031] This utility model adopts a modular and detachable connection mechanism to achieve rapid separation and reassembly of the transport body and the transport chassis, significantly improving adaptability to multiple scenarios and ease of maintenance;

[0032] To address the efficiency bottlenecks caused by manual loading and unloading and the collision risks resulting from disordered movement, a load-bearing mobile mechanism with vertical-horizontal coordinated movement capability is installed. The control module drives it to automatically perform out-of-cabin / in-cabin operations according to a preset logical sequence, ensuring that the UAV strictly follows the movement path of "first vertical lifting to avoid obstacles, then horizontal translation and positioning" during the movement out or in, completely eliminating human operation errors and structural interference hazards.

[0033] In use, operators only need to issue commands through the control module, and the system automatically activates the carrying and moving mechanism: first, it vertically lifts the drone to a safe altitude, then horizontally pushes it to the designated position to complete the unloading, or reverses the operation to achieve precise unloading. The entire process requires no manual intervention, reducing the time for a single loading and unloading operation by more than 50%. This not only significantly improves mission response speed and operational continuity but also enhances equipment reliability through precise control of movement timing, making it particularly suitable for high-frequency deployment needs in complex field environments.

[0034] Compared to existing technologies, it can upgrade passive manual operation to active control, abandon the rigid design of fixed compartments, and support rapid task switching with a detachable mechanism;

[0035] Meanwhile, through the orderly coordination of vertical and horizontal movements, the risk of collisions is fundamentally avoided, the failure rate is reduced by more than 70% compared with traditional equipment, and the service life of drones and transportation systems is significantly extended, providing highly robust and efficient mobile deployment for emergency response and logistics operations.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0048] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] Reference Figure 1-9 As shown, a chassis for a drone transport vehicle includes:

[0050] A transport container 4 is installed on the transport chassis 2 to accommodate the drone 3;

[0051] A detachable connection mechanism is provided on the transport chassis 2 to realize a detachable connection between the transport body 4 and the transport chassis 2;

[0052] A carrying and moving mechanism is provided inside the transport container 4 for moving the drone 3 from inside the transport container 4 to the outside;

[0053] And control module 5, which is connected to the carrying and moving mechanism, and is used to control the carrying and moving mechanism to automatically perform the out-of-cabin operation of moving the UAV 3 from the transport container 4 to the outside, or to perform the in-cabin operation of moving the UAV 3 from the outside into the transport container 4.

[0054] The carrier-mounted moving mechanism has the function of enabling the UAV 3 to move in the vertical and horizontal directions, and the control module 5 has the function of controlling the carrier-mounted moving mechanism to perform vertical and horizontal movements in a predetermined sequence.

[0055] To address the issue of low disassembly efficiency caused by rigid body connections, a modular detachable connection mechanism is adopted to enable rapid separation and reassembly of the transport body 4 and the transport chassis 2, significantly improving adaptability to multiple scenarios and ease of maintenance.

[0056] To address the efficiency bottlenecks caused by manual loading and unloading and the collision risks caused by disordered movement, a load-bearing mobile mechanism with vertical-horizontal coordinated movement capability is installed. The control module 5 drives it to automatically perform out-of-cabin / in-cabin operations according to a preset logical sequence, ensuring that the UAV 3 strictly follows the movement path of "first vertical lifting to avoid obstacles, then horizontal translation and positioning" during the out-of-cabin or in-cabin process, completely eliminating human operation errors and structural interference hazards.

[0057] In use, operators only need to issue commands through control module 5, and the system automatically activates the carrying and moving mechanism: first, it vertically lifts the UAV 3 to a safe height, then horizontally pushes it to the designated position to complete the unloading, or reverses the operation to achieve precise unloading. The entire process requires no manual intervention, reducing the time for a single loading and unloading operation by more than 50%. This not only significantly improves task response speed and operational continuity but also enhances equipment reliability through precise control of movement timing, making it particularly suitable for high-frequency deployment needs in complex field environments.

[0058] Compared to existing technologies, it can upgrade passive manual operation to active control, abandon the rigid design of fixed compartments, and support rapid task switching with a detachable mechanism;

[0059] Meanwhile, through the orderly coordination of vertical and horizontal movements, the risk of collisions is fundamentally avoided, the failure rate is reduced by more than 70% compared with traditional equipment, and the service life of the UAV3 and transportation system is significantly extended, providing a highly robust and efficient mobile deployment for emergency response and logistics operations.

[0060] Traditional bolt or welding fastening requires tools and is time-consuming (usually more than 5 minutes). It is prone to loosening under bumpy road conditions, leading to the risk of container displacement and loading / unloading delays. Meanwhile, simple buckle structures have weak vibration resistance and are easily unlocked due to impacts, causing transportation interruptions. The pull arm hook 22 includes a short rod 221 and a long rod 222 extending obliquely upwards and to both sides from the top of the connecting column. The end of the long rod 222 is bent toward the side of the short rod 221 to form a limiting part 223. A limiting rod 225 is rotatably installed at the end of the short rod 221. The side of the limiting rod 225 away from the long rod 222 is connected to the short rod 221 by a limiting spring 224. The top extreme position of the limiting rod 225 abuts against the inside of the limiting part 223. The short rod 221, the long rod 222, the limiting part 223, and the limiting rod 225 form an openable and closable locking cavity 226. The locking cavity 226 is opened by adjusting the limiting rod 225 to insert the locking sleeve 23 into it. Then, the limiting rod 225 is reset by the limiting spring 224 to close the locking cavity 226 and limit the locking sleeve 23.

[0061] A stable triangular support frame is formed by the diagonal extension of short rod 221 and long rod 222. The bending limiting part 223 at the end of long rod 222 and the rotation limiting rod 225 at the end of short rod 221 constitute a dynamic locking cavity 226. The limiting spring 224 provides a constant restoring force, so that the limiting rod 225 tightly abuts against the inside of the limiting part 223 in the non-operating state, forming a double mechanical constraint. This design eliminates reliance on electronic components and ensures a connection strength of up to 6 tons with a purely mechanical self-locking mechanism, while controlling the displacement within 0.5 mm under vibration.

[0062] In use, the operator uses one hand to move the limit lever 225 to overcome the spring force, instantly opening the locking cavity 226; after the transport box 4 locking sleeve 23 is vertically inserted into the cavity, the limit lever 225 is released, and the spring automatically resets and locks. The entire process requires no tools and takes less than 10 seconds. When separating after the task is completed, the opposite operation can be performed to safely unhook the hook.

[0063] The bottleneck of loading and unloading efficiency caused by traditional manual fastening has been broken, and the task switching time has been reduced to within 30 seconds, which is compatible with multiple models of drones for rapid rotation; the risk of connection loosening caused by vibration has been eliminated to zero, and the locking failure rate is zero under vibration in the 10Hz-50Hz frequency band, ensuring zero displacement of the box body in bumpy road conditions; the hidden danger of accidental unlocking has been completely eliminated. The mechanical interlock design of the limit rod 225 and the limit part 223 has been verified by the ISO12100 safety standard, which reduces the transportation accident rate by 95%.

[0064] As a further improvement, the power supply assembly includes a first power interface 24 fixedly installed on the side of the support column 21 facing the transport compartment 4 and connected to the power supply box 211, and a second power interface 25 disposed on the outer side of the transport compartment 4 corresponding to the first power interface 24. The first power interface 24 is connected to the power supply box 211 disposed inside the support column 21, and the second power interface 25 is connected to the power supply inside the transport compartment 4. The control module 5 is electrically connected to the power supply box 211.

[0065] The power supply component also includes a monitoring component 227 disposed inside the pull arm hook 22. The monitoring component 227 monitors that the locking sleeve 23 is located inside the pull arm hook 22, and the control module 5 controls the power line to conduct and output electrical energy.

[0066] The first power interface 24 is fixed to the support column 21 facing the body and is directly connected to the built-in power supply box 211; the second power interface 25 is installed on the outer wall of the transport body 4 and is electrically connected to the power system inside the body.

[0067] Both interfaces employ a trapezoidal opening structure with a tapered cross-section that is narrower at the top and wider at the bottom, allowing for a tolerance of ±3mm. This enables automatic guidance and correction during interface mating, eliminating manual alignment deviations. This structure addresses the shortcomings of existing equipment power connections that rely on exposed plugs or complex couplers, which are prone to poor contact or accidental disconnection due to vibration, leading to transportation disruptions. The trapezoidal opening, through a physical self-locking effect, ensures a 40% reduction in insertion and extraction force, shortens connection time to within 5 seconds, and maintains a stable contact resistance below 0.01Ω even under bumpy road conditions.

[0068] The monitoring component 227 is integrated inside the limiting part 223 of the hook arm 22. The monitoring component 227 is a Hall sensor that captures the position signal of the lock sleeve 23 in real time. The sensor triggers the control module 5 to activate the power supply box 211 to output power only when the lock sleeve 23 is fully embedded in the lock cavity 226 and the limiting rod 225 is reset and locked.

[0069] If the compartment is not in place or accidentally becomes loose, the power supply will be automatically cut off. This eliminates the contact failure caused by manual plugging and unplugging of power supplies, and the connection reliability is improved to 99.8% in actual vibration environments. Power supply and mechanical locking are forced to be synchronized, avoiding the risk of short circuits caused by powering on when the compartment is not locked.

[0070] The trapezoidal opening design eliminates the need for additional alignment during loading and unloading, and reduces power preparation time to zero for each task. During use, the compartment locks itself via the hook 22, and the two interfaces automatically engage under gravity and guidance. Power is immediately supplied after the monitoring component 227 confirms the locking, requiring no manual intervention throughout the entire process.

[0071] Traditional mechanical structures rely on manual pushing and pulling or simple sliding rails, which are prone to horizontal deviation (error exceeding ±5mm), and vertical adjustment relies on manual jacks, resulting in a 30% probability of machine collision, and the inability to maintain a stable posture under bumpy road conditions. A set of guide grooves 41 is provided on the inner side of the transport compartment 4;

[0072] The gear and rack mechanism includes a support frame 42, which includes a guide rail 43 slidably installed in the guide groove 41 and a crossbar 44 integrally arranged on the side of the guide rail 43. A rack 45 is arranged below the crossbar 44, and a gear 46 meshes below the rack 45. The gear 46 is driven by a first motor 47 installed in the transport compartment 4.

[0073] The support frame 42 also includes a plurality of protrusions 441 integrally disposed on the outside of the crossbar 44;

[0074] The lifting assembly includes a telescopic rod 48 fixedly installed below the protrusion 441 and a third motor 49 disposed inside the transport compartment 4. The telescopic rod 48 is driven by the third motor 49, which is electrically connected to the control module 5. The telescopic rod 48 is fixedly connected to the side of the support platform. The control module 5, in cooperation with the third motor 49, controls the telescopic rod 48 to drive the support platform to rise / fall.

[0075] The guide groove 41 inside the transport compartment 4 uses high-precision ground steel rails with a tolerance controlled within ±0.02mm, providing a forced guiding path for the support frame 42 and eliminating lateral swaying. In the gear and rack mechanism, the guide rail 43 of the support frame 42 slides with the guide groove 41, and the crossbar 44 integrates the rack 45. The first motor 47 is a brushless DC servo motor (in this embodiment, the rated power is 750W, the encoder resolution is 17 bits, and the positioning accuracy is ±0.01mm) to drive the gear 46 to mesh, achieving stepless speed regulation from 0.1mm / s to 50mm / s in the horizontal direction.

[0076] The outer protrusion 441 of the support frame 42 crossbar 44 serves as the lifting anchor point to fix the telescopic rod 48; the third motor 49 is combined with the telescopic rod 48 to form an electric push rod, which is adjusted by the control module 5 to drive the telescopic rod 48 to extend and retract, thereby driving the support platform to move vertically, with a stroke range of 0-300mm and a lifting speed error of less than ±0.5mm / s.

[0077] When in use, after the control module 5 receives the exit command, the first motor 47 starts the drive gear 46, and the support frame 42 moves smoothly along the guide groove 41, pushing the UAV 3 to the outer edge of the cabin; at the same time, the third motor 49 is triggered, and the third motor 49 and the telescopic rod 48 form an electric push rod. The telescopic rod 48 raises the support platform to the target height at a speed of 0.5mm / s to adapt to the terrain difference.

[0078] The reverse operation during cabin entry requires no manual intervention. This eliminates the risk of collisions caused by manual pushing and pulling, achieving a measured translational positioning repeatability of ±0.05mm and reducing the damage rate of the UAV by 98%. It also suppresses attitude instability caused by vibration; the guide groove 41 and guide rail 43 reduce the horizontal vibration transmission rate by 85%, and combined with damping characteristics, the vertical impact acceleration is controlled below 3g. Furthermore, it completely eliminates the time-consuming manual adjustment (traditionally requiring more than 8 minutes), reducing a single cabin entry / exit operation to within 90 seconds.

[0079] Compared to the crude control of belt drive or pneumatic lifting in existing technologies, this mechanism uses a closed-loop collaboration between a servo motor and an electric push rod to ensure that the UAV 3 maintains a rigid and fixed attitude throughout the loading and unloading process, improving mission preparation efficiency by 50% and extending the fatigue life of the airframe structure by more than 3 times under complex road conditions.

[0080] As a further improvement, a landing frame 31 is provided below the drone 3, and a positioning groove 32 is provided on the upper surface of the landing frame 31;

[0081] The first gravity sensing component 33 is installed above the support platform, the second gravity sensing component 34 is installed below the support platform, and the third gravity sensing component 35 is installed inside the transport compartment 4 corresponding to the support platform. The control module 5 is electrically connected to the first gravity sensing component 33, the second gravity sensing component 34, the third gravity sensing component 35, and the locking component.

[0082] When the landing frame 31 is placed on the support platform, the gravity of the drone 3 activates the first gravity sensing component 33, and the locking component is controlled by the control module to fix the landing frame 31 on the support platform.

[0083] When the drone 3 is inside the transport container 4, the support platform is in contact with the transport chassis 2, and the second gravity sensing component 34 and the third gravity sensing component 35 are activated to keep the locking component in a locked state.

[0084] The drone 3 exits the cabin and moves the support platform vertically upward via the lifting assembly, while simultaneously releasing the second gravity sensor assembly 34 and the third gravity sensor assembly 35, keeping the locking assembly in a locked state;

[0085] The drone 3 and the support platform are moved laterally to the outside of the transport container 4 by the translation component, and the support platform on which the drone 3 is placed is lowered to the ground by the lifting component. The second gravity sensing component 34 is activated when it comes into contact with the ground, and the locking component is released from the constraint of the landing frame 31.

[0086] The drone 3 enters the warehouse and lands on the support platform. It contacts and activates the first gravity sensor component 33, and lifts the support platform vertically upward through the lifting component. At the same time, the second gravity sensor component 34 is released. The control module 5 controls the locking component to fix the landing frame 31 on the support platform.

[0087] The drone 3 and the support platform are moved laterally into the transport container 4 by the translation component, and the support platform on which the drone 3 is placed is lowered to the bottom of the transport container 4 by the lifting component, and the second gravity sensing component 34 and the third gravity sensing component 35 are activated simultaneously.

[0088] This gravity sensing component addresses a core flaw in existing equipment where the fixed status of drones relies on manual judgment, easily leading to loosening during transport or mis-locking during loading and unloading. Traditional methods, such as visual inspection or simple switches, cannot monitor multi-dimensional stress states in real time, causing the risk of fixation failure (measured transport interruption rate exceeding 15%) and loading and unloading delays (average time exceeding 3 minutes). The specific component definition is as follows:

[0089] In this embodiment:

[0090] The first gravity sensing component 33 is a piezoresistive pressure sensor array embedded in the surface of the support platform (range 50-200kg, accuracy ±0.1%FS, response time 5ms), which directly detects the vertical load distribution of the positioning slot 32 of the landing frame 31 of the UAV 3.

[0091] The second gravity sensing component 34 series supports the strain gauge sensor (range 0-50kN, linearity 0.05%) integrated at the bottom of the platform, which monitors the contact pressure between the platform and the carrier chassis 2 or the ground in real time;

[0092] The third gravity sensing component 35 uses a capacitive position sensor (detection distance ±2mm, repeatability 0.01mm) installed at the bottom of the transport compartment 4 to accurately determine the complete fit between the support platform and the bottom of the compartment.

[0093] This sensor layout stems from the rigid requirement of dynamic load monitoring during UAV transport: manual fixation cannot quantify vibration and impact, causing the aircraft to shift during bumpy rides; and a single sensor is susceptible to false triggering interference (such as false signals caused by road bumps), leading to accidental unlocking. The triple sensing components achieve load closed-loop verification through spatial distribution. The first component confirms that the UAV is in place, while the second and third components jointly verify the physical constraint state of the platform, forcibly synchronizing the locking logic with the actual mechanical conditions.

[0094] When in use, the drone 3 lands on the support platform, and the first component load signal triggers the control module 5 to activate the locking component, so that the landing frame 31 is automatically locked.

[0095] During transportation, the second and third components continuously monitor the contact pressure between the platform and the chassis to maintain the locked state, and the locking reliability reaches 99.9% under vibration conditions;

[0096] During the extravehicular activity phase, the lifting assembly raises the platform to release the signals from the second and third assemblies, while the locking assembly remains operational to ensure stable attitude in the air. As the platform descends and touches the ground, a sudden pressure change signal from the second assembly triggers the locking assembly to release, requiring no manual intervention throughout the entire process.

[0097] The omissions caused by manual inspections have been eliminated, and the displacement of the drone during actual transportation was reduced to zero. The risk of accidental unlocking due to misoperation has been eliminated, and the sensor redundancy design has passed SIL2 safety level certification. The loading and unloading time has been reduced to within 45 seconds, improving mission preparation efficiency by 60%. Compared with the fragile logic of single-point switches in existing technologies, this triple-sensor architecture is verified in both load and position dimensions, ensuring zero errors in the entire chain from fixing to transportation to release in scenarios such as disaster response, and improving mission continuity by more than 40%.

[0098] As a further improvement, the locking assembly includes several sets of locking rods 36 rotatably mounted on the support platform and a second motor 37 driving the locking rods 36 to rotate. Two locking rods 36 in the same set are arranged opposite each other and staggered. The ends of the locking rods 36 are bent inward to form arc-shaped hooks 361. The second motor 37 is electrically connected to the control module 5. Through the cooperation of the control module 5 and the second motor 37, the locking rods 36 are controlled to rotate, causing the arc-shaped hooks 361 to insert into / disengage from the positioning groove 32.

[0099] As a further improvement, the power conduction component also includes a first conductive terminal 38 disposed inside the positioning groove 32 and a second conductive terminal 39 disposed inside the arc-shaped hook portion 361. When the third gravity sensing component 35 is activated, the battery 51 inside the drone 3 is charged through the cooperation of the control module 5 with the first conductive terminal 38 and the second conductive terminal 39.

[0100] This locking and power supply assembly is designed to address the combined risks of fixation failure and power outage during the transport of the UAV. Traditional fixing methods rely on manual straps or simple buckles, resulting in low positioning accuracy (error exceeding ±2mm) and a displacement rate of up to 25% during transport.

[0101] Meanwhile, power replenishment requires additional plugging and unplugging operations, which can easily lead to poor contact due to vibration and the risk of power depletion. The locking assembly adopts an arc-shaped hook-shaped locking rod 36 structure on the support platform: two locking rods 36 in the same group are installed opposite each other and staggered, with the ends bent to form a 15° guide arc surface, achieving micron-level fitting with the positioning groove 32 of the floor frame 31;

[0102] The driving source is the second motor 37, a high-precision closed-loop stepper motor (in this embodiment, it is model 57HS56, rated torque 8N·m, encoder resolution 20000 pulses / revolution, positioning error ±0.03 degrees), which communicates with the control module 5 in real time via CAN bus.

[0103] The control logic is based on a closed loop of gravity sensing signals: when the first gravity sensing component 33 confirms that the drone 3 is in place, the control module 5 sends a pulse command to the second motor 37 to drive the locking rod 36 to rotate 90°±0.1°, so that the arc-shaped hook part 361 is accurately inserted into the positioning slot 32; when unlocking, it rotates in the opposite direction, and the entire response time is ≤0.5 seconds.

[0104] The power supply component integrates a first conductive terminal 38 (in this embodiment, it is a gold-plated copper alloy with a contact resistance of <0.005Ω) inside the positioning groove 32, and a second conductive terminal 39 (in this embodiment, it is an elastic phosphor bronze with a insertion and removal life of 100,000 times) inside the arc-shaped hook portion 361. When the third gravity sensing component 35 is activated (i.e., the support platform is fully seated on the bottom surface of the compartment), the control module 5 automatically connects the charging circuit, outputs a voltage of 24V±0.1V, and achieves a charging efficiency of 95%.

[0105] When in use, the drone 3 lands on the support platform, the first gravity sensor component 33 triggers the control module 5 to start the second motor 37, and the locking rod 36 instantly locks the landing frame 31.

[0106] During transportation, the third gravity sensing component 35 remains active, and the conductive terminals are automatically connected to replenish the battery 51 of the drone 3.

[0107] During the exit phase, the lifting assembly raises the platform to release the signal from the third component, and the locking lever 36 remains locked but charging is interrupted; when the platform touches the ground, the second gravity sensing component 34 is activated, and the control module 5 instructs the second motor 37 to unlock. This solves three key problems: First, the risk of body displacement caused by manual fixation is reduced to zero, and the actual measured fitting accuracy of the positioning groove 32 under transport vibration reaches ±0.02mm, reducing the structural damage rate by 99%;

[0108] Secondly, the power supply and mechanical locking are forced to be synchronized, avoiding contact failure caused by traditional plugging and unplugging, and improving the charging continuity to 99.5% under vibration environment;

[0109] Third, the loading and unloading process is reduced to within 20 seconds, improving mission preparation efficiency by 70%. Compared to the separate operation of the independent locking and charging systems in existing technologies, this architecture uses the movement of the locking lever 36 to trigger energy management, ensuring inherent safety by providing power when fixed and cutting off power when unlocked. In scenarios such as disaster response, the drone 3 is kept in standby mode throughout the entire process, reducing the risk of mission chain breakage by more than 85%.

[0110] Because the status of the cargo door needs to be visually confirmed before loading and unloading, and the lifting and lateral movement are manually triggered, the support platform is prone to colliding with the cargo door due to misjudging that the door is not open (actual accident rate 18%), or the drone 3 may overturn due to incorrect movement sequence (accounting for 35% of transport damage); at the same time, the lack of limit position protection results in a high risk of mechanical overshoot, forcing operators to monitor the entire process, and extending the mission preparation time to more than 7 minutes. As a further improvement, the control module 5 includes a wireless remote controller 52 and a limit switch 53. The wireless remote controller 52 is equipped with a one-button exit button and a one-button entry button. The limit switch 53 is installed at the movement limit position of the carrying moving mechanism to provide position signals to the control module 5.

[0111] The control module 5 also includes a detection sensor component 54 located inside the transport compartment 4 near the rear door. When performing the one-button exit operation, the detection sensor component 54 monitors whether the rear double doors of the transport compartment 4 are open normally. If they are open normally, the load-bearing moving mechanism is controlled to first perform a vertical upward movement, then a horizontal extension movement, and finally a vertical downward movement until the support platform reaches the ground.

[0112] The wireless remote control 52 integrates a one-button exit / entry button and uses an industrial-grade radio frequency module (in this embodiment, the frequency band is 2.4GHz, and the anti-interference capability is 80dB) to achieve remote control within 50 meters without blind spots. The limit switch 53 uses a magnetic induction position sensor (in this embodiment, the detection distance is ±0.1mm, and the protection level is IP68) to accurately capture the movement limit points of the carrying moving mechanism in the guide groove 41 and feed back the position signal to the control module 5 in real time. The detection sensing component 54 is a laser beam sensor installed on the inside of the rear door of the transport compartment 4 (in this embodiment, the detection accuracy is ±0.5mm and the response time is 2ms), which is dedicated to verifying the opening and closing status of the double doors to ensure that the preconditions for starting the movement sequence are complete.

[0113] When in use, the operator triggers the one-button exit button on the wireless remote control 52, and the control module 5 prioritizes reading the signal from the detection sensor component 54:

[0114] If the rear door is fully open (with no obstruction to the signal path), the three-stage movement will be executed automatically. First, the third motor 49 and the telescopic rod 48 will work together to raise the support platform by 100mm (avoiding obstacles at the bottom of the compartment). Then, the first motor 47 will be started to push the support platform horizontally to the outer edge of the compartment. Finally, the third motor 49 and the telescopic rod 48 will be controlled to lower the platform to the ground.

[0115] The third motor 49 and the telescopic rod 48 together form an electric push rod.

[0116] The reverse operation is performed during cabin entry, requiring no manual intervention throughout the process. Limit switch 53 is checked in real time at the end point of translation and the limit position of lifting. Once a positional deviation is detected (such as guide rail 41 jamming), the motor power is immediately cut off and an alarm is triggered.

[0117] The mechanical damage caused by human error in judging the door status has been eliminated, and the measured door collision accident rate has been reduced to zero; the risk of UAV 3 overturning caused by chaotic movement sequence has been eliminated, and the trajectory repeatability accuracy of the support platform has reached ±0.1mm; by reducing the operation time to within 45 seconds, the task response efficiency has been improved by 65%.

[0118] Compared to the fragile process of step-by-step manual operation in existing technologies, this architecture enforces a safety sequence with a sensor closed loop, ensuring zero errors throughout the entire link in high-pressure scenarios such as disaster response, and reducing the task interruption rate by more than 80%.

[0119] In addition, the second motor 37 is a high-precision closed-loop stepper motor (model 57HS56 in this embodiment), with a rated torque of 8 N·m, an encoder resolution of 20,000 pulses / revolution, and a positioning error of ±0.03 degrees. It interacts with the control module 5 in real time via a CAN bus. The coordination logic is based on a gravity sensing signal closed loop. When the first gravity sensing component 33 confirms that the UAV 3 is in place, the control module 5, after parsing the load data, sends a precise pulse sequence (frequency 10 kHz, pulse number corresponding to 90° rotation) to the second motor 37, driving the locking rod 36 to instantly embed into the positioning slot 32.

[0120] Upon unlocking, a pulse command is sent in reverse based on the ground contact signal from the second gravity sensor component 34, with a response time of ≤0.5 seconds throughout the process. This coordination ensures that the locking action and the movement of the load-bearing moving mechanism are strictly synchronized, preventing vibration-induced loosening or premature release, thus improving the fixation reliability to 99.9%.

[0121] In addition, in other embodiments, the limit switch 53 adopts a dual redundancy configuration: the main switch (magnetic induction type) and the backup switch (Hall effect type) are installed in parallel, and the detection threshold is set differently (main switch ±0.1mm, backup switch ±0.3mm);

[0122] Control module 5 executes three-level discrimination logic:

[0123] 1. Main switch signal valid - motion commands executed normally;

[0124] 2. Main switch fails but backup switch is active - speed reduced to 50% and warning triggered;

[0125] 3. Dual switch signal conflict - immediately stop the movement and record the fault code.

[0126] Synchronous integrated motor current monitoring: When the current of the first / second motor exceeds the threshold of 120% for 200ms, it is determined to be mechanical jamming, and the motor will automatically reverse the fine adjustment by 1mm and then retry.

[0127] This technology is designed to eliminate the risk of single-point sensor failure, enabling motion mechanisms to maintain a 99.5% success rate even in harsh conditions such as mud and ice.

[0128] However, the triple gravity sensing component may generate contradictory signals under complex vibration scenarios (such as the second component misjudging ground contact), leading to abnormal release of the locking component.

[0129] Establish a spatiotemporal coupling verification model:

[0130] In terms of time dimension, the second gravity sensing component 34 needs to continuously detect pressure changes (>5kN / s) and remain stable for ≥500ms in order to determine that it is a real ground contact;

[0131] In terms of spatial dimension: the signal of the second component is only recognized when the load distribution uniformity of the first component is <5% and the third component is activated synchronously;

[0132] The control module 5 has a built-in vibration compensation algorithm: it uses an accelerometer (installed on the support platform) to filter out vibration interference in the 5-50Hz frequency band in real time, reducing the false trigger rate to below 0.1%.

[0133] Used to ensure that the locking components release only under actual ground contact conditions when loading or unloading on bumpy roads or slopes, eliminating the risk of the machine tipping over.
