Description

Technical Field

[0001] This invention relates to the field of drone auxiliary equipment technology, specifically to a take-off and landing facility for drone logistics delivery based on road-air cooperation. Background Technology

[0002] Against the backdrop of the rapid development of drone logistics delivery technology, the road-air collaborative model has become an important development direction for the logistics industry due to its ability to effectively expand delivery coverage and improve last-mile delivery efficiency. However, current drone take-off and landing facilities adapted to road-air collaborative scenarios still have many technical shortcomings, making it difficult to meet actual delivery needs. Existing drone take-off and landing facilities are mostly fixed structures or only have simple support functions. In road-air collaborative scenarios, take-off and landing facilities often need to be moved with logistics vehicles to temporary stations, such as suburban roads or open spaces. The road surfaces in these areas often have problems such as inclination and unevenness, affecting the safety and stability of take-off and landing. There are already drone take-off and landing platform devices on the market, such as the prior art EP4053021B1, which discloses a drone airport and a drone system. The drone airport includes a support base, a landing pad, a protective cover, and a protective cover opening and closing drive device. If the protective cover is opened, the drone is parked on the landing pad and takes off from the landing pad. When the protective cover is in the closed position, it protects the unmanned aerial vehicle (UAV) from damage and contamination caused by external rainwater, impurities, etc. Existing take-off and landing platforms can meet the functions of UAV take-off and landing and protection, but there is still room for improvement in the horizontal adaptability of the take-off and landing platforms. Summary of the Invention

[0003] The purpose of this invention is to provide a take-off and landing facility for UAV logistics delivery based on road-air cooperation, which solves the problems of poor horizontal adaptability and insufficient compatibility of existing take-off and landing platforms. The take-off and landing facility of this invention has the advantages of strong adaptability, high safety and high flexibility.

[0004] To address the aforementioned technical problems, the present invention specifically provides the following technical solution: a take-off and landing facility for unmanned aerial vehicle (UAV) logistics delivery based on road-air cooperation, comprising a vehicle body with a mounting slot, an adjustment component built into the mounting slot, and a take-off and landing platform positioned above the adjustment component. The adjustment component is capable of adjusting the horizontal angle of the take-off and landing platform. There is a gap between the edge of the take-off and landing platform and the mounting slot.

[0005] The vehicle body of this invention is a mobile carrier that can be moved to temporary stations according to delivery needs. Compared with existing fixed take-off and landing facilities, the take-off and landing facilities of this invention are more flexible. Furthermore, the mounting slot provides installation space for the adjustment components, which are used to adjust the horizontal angle of the take-off and landing platform. This can offset the impact of the road surface tilt at the temporary station, prevent the center of gravity from shifting due to the platform tilt during take-off and landing of the drone, reduce the risk of tipping over and falling, and improve take-off and landing safety. The distance between the edge of the take-off and landing platform and the mounting slot can prevent structural interference between the take-off and landing platform and the vehicle body during angle adjustment.

[0006] According to one embodiment of the present invention, the adjustment assembly includes a first base plate disposed on the bottom surface of the mounting groove. The first base plate has at least three drive motors placed at different positions. The output shafts of the drive motors are horizontally arranged, and the ends of the output shafts are connected to a first swing arm perpendicular to its axis. The ends of the first swing arm are connected to a second swing arm. The bottom of the lifting platform is connected to the second base plate. The bottom surface of the second base plate has a mounting plate disposed perpendicular to its surface, and the second swing arm is connected to the mounting plate.

[0007] The second base plate is located above the first base plate and the second swing arm. The drive motors on the first base plate are placed along its edge with a spacing of 90°. That is, the first base plate can be a quadrilateral structure with at least one drive motor on each side. Thus, the output shafts of adjacent drive motors are at a 90° angle. In this structural configuration, the mounting plates on the first base plate form a quadrilateral structure. The second swing arm is connected to each mounting plate. The horizontal angle of the second base plate above can be controlled by controlling the drive motor, thereby controlling the horizontal angle of the lifting platform.

[0008] In the adjustment assembly, the first base plate serves as the installation reference to prevent displacement during the operation of the drive motor. The drive motor is placed at 90° intervals along the edge of the first base plate, which can apply force to the second base plate from multiple directions, eliminating dead angles in level adjustment and offsetting the tilting effect of uneven road surfaces such as suburbs and open areas in road-air cooperative scenarios. Secondly, the drive motor, together with the first and second swing arms, controls the tilting amplitude of the second base plate, thereby adjusting the horizontal angle of the take-off and landing platform and preventing the UAV from shifting its center of gravity due to platform tilt. In addition, during the adjustment of the level of the second base plate, it helps to remove debris or water from the second base plate and the take-off and landing platform above it, reducing or eliminating the interference of debris or water on the take-off and landing of the UAV.

[0009] According to one embodiment of the present invention, each drive motor is connected above a third substrate. The third substrate and the mounting plate are spaced apart. The third substrate is used to provide integral support and fixation for the drive motors that are dispersed along the edge of the first substrate, suppressing displacement or axial offset of the drive motors due to vibration during operation. At the same time, the spaced distance between the third substrate and the mounting plate provides sufficient space for the swinging of the first and second swing arms, avoiding structural interference between the third substrate and the mounting plate when the adjustment assembly is working.

[0010] According to one embodiment of the present invention, the take-off and landing platform includes take-off and landing modules arranged in an array at intervals. Each take-off and landing module has a take-off and landing plate, and a support base plate perpendicularly arranged to the bottom of the take-off and landing plate is slidably connected to it. One end of the support base plate is connected to a first connecting pipe perpendicularly arranged to its surface, and the other end is connected to a second connecting pipe perpendicularly arranged to its surface. A mounting base plate is connected to the bottom of the support base plate through a first elastic element. The slidable connection between the take-off and landing plate and the support base plate can form a buffer linkage with the first elastic element at the bottom of the support base plate, effectively absorbing the vertical impact force during the take-off and landing of the UAV, reducing vibration damage to the fuselage and collision with cargo. The first and second connecting pipes at both ends of the support base plate can enhance the structural rigidity of a single module, preventing the take-off and landing module from deforming under stress, and providing a stable reference for the array splicing of take-off and landing modules, preventing loosening and displacement at the splicing points. Furthermore, the mounting base plate is detachably connected to the second base plate of the adjustment component through fasteners, facilitating the rapid assembly of the take-off and landing platform and the adjustment component, and also allowing for individual disassembly and replacement in case of a single module failure, without the need for overall disassembly, reducing maintenance costs and time.

[0011] The mounting base plate is connected to the second base plate of the adjustment assembly. The overall area of ​​the landing platform can be controlled by increasing or decreasing the number of landing modules, solving the adaptation limitations of traditional fixed-area platforms. The mounting base plate is detachably connected to the bottom second base plate via fasteners.

[0012] According to one embodiment of the present invention, there is a gap between the landing plates of adjacent landing modules. The landing plates have an inner groove near the first or second connecting pipe to increase the gap between the landing plates of the two landing modules. This gap between the landing plates of adjacent landing modules allows rainwater, pebbles, fallen leaves, and other debris to fall directly from the gap, preventing debris from accumulating on the landing plate surface and affecting the stability of the UAV's takeoff and landing. It also prevents debris from getting stuck in the sliding connection between the landing plate and the supporting base plate, ensuring smooth sliding. Furthermore, the inner groove near the first or second connecting pipe further increases the gap between adjacent landing plates, improving debris removal and overall ventilation of the landing platform. This helps the UAV dissipate heat quickly after takeoff and landing, reducing the impact of heat buildup on equipment performance. The increased gap also facilitates observation of the bottom structure of the landing plates by personnel, reducing the difficulty of maintenance and inspection.

[0013] According to one embodiment of the present invention, a snap-fit ​​plate is connected to the bottom surface of the end of the adjacent second connecting pipe of the landing plate. The snap-fit ​​plate is a flexible bent plate that can contact or separate from the surface of the second connecting pipe. The snap-fit ​​plate can conform to the surface of the second connecting pipe to form an auxiliary fixation, limiting the lateral displacement of the landing plate relative to the supporting base plate when the UAV takes off or lands, or when the adjustment component adjusts the horizontal angle. This ensures the positional stability of the landing plate when carrying the UAV and avoids uneven stress on the UAV landing gear due to plate offset. At the same time, the flexible material can buffer minor collisions between the landing plate and the second connecting pipe, reduce component wear caused by hard friction, and extend the service life of the landing module.

[0014] According to one embodiment of the present invention, the first elastic member has a side plate on its side, and at least one end of the side plate is bent downwards. During the deformation of the first elastic member, the bent end of the side plate can contact or separate from the surface of the mounting base plate or the second substrate. The side plate is used to enhance the lateral structural stiffness of the first elastic member, prevent it from laterally shifting or bending under the impact of the UAV take-off and landing, ensure that the first elastic member always deforms in the vertical direction to accurately absorb the impact force, and avoid the take-off and landing plate tilting due to the first elastic member shifting, which would affect the safety of UAV take-off and landing; the downward bending of at least one end of the side plate allows the bent end to contact the surface of the mounting base plate or the second substrate when the first elastic member is impacted and deformed, forming a limiting structure for the deformation of the first elastic member, preventing the first elastic member from being over-compressed.

[0015] According to one embodiment of the present invention, a guardrail is provided on the edge of the vehicle body. This guardrail is used to physically prevent the drone from accidentally sliding out of the vehicle body's range during takeoff and landing or when the vehicle body is moving, thus preventing the drone from falling due to vibration, wind interference, or operational deviation.

[0016] According to one embodiment of the present invention, a limiting component is provided on one side of the vehicle body of the mounting slot. The limiting component has a vertically arranged support column, and a first groove is vertically opened on one side of the support column. The first groove contains a movable block that can move. The movable block is hinged to a first limiting rod, and a second limiting rod is hinged to the end of the first limiting rod. A pressure block is provided at the end of the second limiting rod. The vertically arranged support column is used to provide support for the entire limiting component, preventing the limiting component from tipping over due to force when fixing the drone. The first groove vertically opened on one side of the support column provides a directional displacement channel for the built-in movable block. The limiting height can be changed by adjusting the position of the movable block to adapt to drones of different body heights. The first limiting rod hinged to the movable block and the second limiting rod hinged to the end of the first limiting rod can flexibly adjust their angles through the double-hinged structure, so that the pressure block at the end of the second limiting rod can fit against the upper part of the drone, avoiding hard contact damage to the body. The pressure block is used to fix the drone and prevent the drone from shifting or slipping due to vehicle body movement or external wind force.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention, by setting adjustment components, achieves adjustment of the horizontal angle of the take-off and landing platform, offsetting the influence of road surface inclination and preventing the center of gravity from shifting due to platform tilt during drone take-off and landing, thus reducing the risk of tipping over and falling. Furthermore, this invention adopts a modular take-off and landing platform design, controlling the platform area by increasing or decreasing the number of interval array take-off and landing modules to adapt to the take-off and landing requirements of cargo drones ranging from small to large; simultaneously, the take-off and landing modules can be disassembled and assembled, enabling rapid replacement in case of individual module failure, reducing maintenance costs and time. Moreover, the solution of this invention has limiting components and optional buffer components, which can both secure the drone with pressure blocks and absorb contact impact forces, preventing damage to the fuselage and cargo.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1:

[0031] As shown in the attached figure Figure 1 - Appendix Figure 6As shown, a take-off and landing facility for unmanned aerial vehicle (UAV) logistics delivery based on road-air cooperation includes a vehicle body 10. A mounting slot 15 is provided on the vehicle body 10. An adjustment component 60 is built into the mounting slot 15. A take-off and landing platform 50 is located above the adjustment component 60. The adjustment component 60 can adjust the horizontal angle of the take-off and landing platform 50. There is a gap between the edge of the take-off and landing platform 50 and the mounting slot 15.

[0032] The vehicle body 10 of the present invention is a mobile carrier that can be moved to a temporary station according to delivery needs. Compared with the existing fixed take-off and landing facilities, the take-off and landing facilities of the present invention are more flexible. Furthermore, the mounting slot 15 provides installation space for the adjustment component 60. The adjustment component 60 is used to adjust the horizontal angle of the take-off and landing platform 50, which can offset the influence of the road surface tilt of the temporary station, prevent the center of gravity of the drone 40 from shifting due to the tilt of the platform when taking off and landing, reduce the risk of rollover and fall, and improve take-off and landing safety. The distance between the edge of the take-off and landing platform 50 and the mounting slot 15 can avoid structural interference between the take-off and landing platform 50 and the vehicle body 10 during the angle adjustment process.

[0033] The temporary sites referred to in this invention include, but are not limited to, suburban roads or open spaces. The road surfaces in these areas often have problems such as inclination and unevenness, which affect the safety and stability of take-off and landing. If a fixed or non-adjustable take-off and landing platform is used, the tilt of the road surface can easily cause the center of gravity of the UAV to shift during take-off and landing, increasing the risk of the UAV tipping over or crashing, and seriously affecting the safety and stability of take-off and landing.

[0034] The adjustment assembly 60 includes a first base plate 61 disposed on the bottom surface of the mounting groove 15. The first base plate 61 has at least three drive motors 62 with different placement positions. The output shafts of the drive motors 62 are horizontally arranged, and the ends of the output shafts are connected to a first swing arm 63 perpendicular to its axis. The ends of the first swing arm 63 are connected to a second swing arm 64. The bottom of the lifting platform 50 is connected to a second base plate 65. The bottom surface of the second base plate 65 has a mounting plate 66 disposed perpendicular to its surface. The second swing arm 64 is connected to the mounting plate 66.

[0035] The second substrate 65 is disposed above the first substrate 61 and the second swing arm 64. The drive motors 62 on the first substrate 61 are placed along its edges with a spacing angle of 90°. That is, the first substrate 61 can be a quadrilateral structure, with at least one drive motor 62 disposed on each side. Thus, the output shafts of adjacent drive motors 62 have an angle of 90°. In this structural configuration, the mounting plates 66 on the first substrate 61 form a quadrilateral structure. The second swing arm 64 is connected to each mounting plate 66. The horizontal angle of the second substrate 65 above can be controlled by controlling the drive motors 62, thereby controlling the horizontal angle of the lifting platform 50.

[0036] In the adjustment assembly 60, the first base plate 61 serves as the mounting reference to prevent displacement of the drive motor 62 during operation. The drive motor 62 is placed at 90° intervals along the edge of the first base plate 61, which allows force to be applied to the second base plate 65 from multiple directions, eliminating dead angles in level adjustment and offsetting the tilting effect of uneven road surfaces such as suburbs and open areas in road-air cooperative scenarios. Secondly, the drive motor 62, in conjunction with the first swing arm 63 and the second swing arm 64, controls the tilting amplitude of the second base plate 65, thereby adjusting the horizontal angle of the take-off and landing platform 50 and preventing the UAV 40 from shifting its center of gravity due to platform tilt. In addition, during the adjustment of the level of the second base plate 65, it helps to remove debris or water from the second base plate 65 and the take-off and landing platform 50 above it, reducing or eliminating the interference of debris or water on the take-off and landing of the UAV 40.

[0037] Each drive motor 62 is connected above a third base plate 67. The third base plate 67 and the mounting plate 66 are spaced apart. The third base plate 67 is used to provide overall support and fixation for the drive motors 62 that are distributed along the edge of the first base plate 61, suppressing displacement or axial offset of the drive motors 62 due to vibration during operation. At the same time, the spaced distance between the third base plate 67 and the mounting plate 66 provides sufficient space for the swing of the first swing arm 63 and the second swing arm 64, and avoids structural interference between the third base plate 67 and the mounting plate 66 when the adjustment assembly 60 is working.

[0038] The take-off and landing platform 50 includes take-off and landing modules arranged in an array at intervals. Each take-off and landing module has a take-off and landing plate 51. A support base plate 52 is slidably connected to the bottom of the take-off and landing plate 51 and is perpendicular to it. One end of the support base plate 52 is connected to a first connecting pipe 53 that is perpendicular to its surface, and the other end is connected to a second connecting pipe 57 that is perpendicular to its surface. A mounting base plate 56 is connected to the bottom of the support base plate 52 through a first elastic member 54. The take-off and landing platform 51 is slidably connected to the support base plate 52, which can work with the first elastic element 54 at the bottom of the support base plate 52 to form a buffer linkage, effectively absorbing the vertical impact force when the UAV 40 takes off and lands, reducing vibration damage to the fuselage and collision with cargo. The first connecting pipe 53 and the second connecting pipe 57 at both ends of the support base plate 52 can enhance the structural rigidity of the individual module, prevent the take-off and landing module from deforming under stress, and provide a stable reference for the splicing of the take-off and landing module array, preventing loosening and displacement at the splicing point. Furthermore, the mounting base plate 56 is detachably connected to the second base plate 65 of the adjustment component 60 through fasteners, which facilitates the quick assembly of the take-off and landing platform 50 and the adjustment component 60, and can also be disassembled and replaced individually in case of failure of a single module, without the need for overall disassembly, reducing maintenance costs and time.

[0039] The mounting base plate 56 is connected to the second base plate 65 of the adjustment assembly 60. By increasing or decreasing the number of take-off and landing modules, the overall area of ​​the take-off and landing platform 50 can be controlled, solving the adaptation limitations of traditional fixed-area platforms. The mounting base plate 56 is detachably connected to the bottom second base plate 65 via fasteners.

[0040] The second connecting pipe 57 between the take-off and landing modules in the array is coaxial. The second connecting pipe 57 of the take-off and landing modules at the beginning and end of the take-off and landing platform 50 is provided with a connector 59. The optical shaft with threads at both ends can be inserted into the second connecting pipe 57 between the take-off and landing modules. Then, the connector 59 is threaded to the beginning and end of the optical shaft and abuts against the second connecting pipe 57, so that the various take-off and landing modules of the take-off and landing platform 50 can form an assembly relationship.

[0041] The first connecting pipe 53 between the take-off and landing modules in the array is coaxial. The first connecting pipe 53 of the take-off and landing modules at the beginning and end of the take-off and landing platform 50 is provided with a connector 59. The optical shaft with threads at both ends can be inserted into the first connecting pipe 53 between the take-off and landing modules. Then, the connector 59 is threaded to the beginning and end of the optical shaft and abuts against the first connecting pipe 53, so that the various take-off and landing modules of the take-off and landing platform 50 can form an assembly relationship.

[0042] There is a gap between the landing plates 51 of adjacent landing modules. The landing plates 51 have an inner groove near the first connecting pipe 53 or the second connecting pipe 57 to increase the gap between the landing plates 51 of the two landing modules. This gap allows rainwater, pebbles, fallen leaves, and other debris to fall directly from the gap, preventing debris from accumulating on the surface of the landing plates 51 and affecting the stability of the UAV 40 during takeoff and landing. It also prevents debris from getting stuck in the sliding connection between the landing plates 51 and the supporting base plate 52, ensuring smooth sliding. Furthermore, the inner groove on the landing plates 51 near the first connecting pipe 53 or the second connecting pipe 57 further increases the gap between adjacent landing plates 51, improving debris removal and overall ventilation of the landing platform 50. This helps the UAV 40 dissipate heat quickly after takeoff and landing, reducing the impact of heat buildup on equipment performance. The increased gap also makes it easier for staff to observe the bottom structure of the landing plates 51, reducing the difficulty of maintenance and inspection.

[0043] A snap-fit ​​plate 58 is connected to the bottom surface of the end of the second connecting pipe 57 adjacent to the landing plate 51. The snap-fit ​​plate 58 is a flexible bent plate that can contact or separate from the surface of the second connecting pipe 57. The snap-fit ​​plate 58 can conform to the surface of the second connecting pipe 57 to form an auxiliary fixation, limiting the lateral displacement of the landing plate 51 relative to the supporting base plate 52 when the UAV 40 takes off or lands and impacts or when the adjustment component 60 adjusts the horizontal angle. This ensures the positional stability of the landing plate 51 when carrying the UAV 40 and avoids uneven stress on the UAV landing gear due to plate offset. At the same time, the flexible material can buffer the slight collision between the landing plate 51 and the second connecting pipe 57, reduce the wear of components caused by hard friction, and extend the service life of the landing module.

[0044] The first elastic member 54 has a side plate 55 on its side, with at least one end of the side plate 55 bent downwards. During the deformation of the first elastic member 54, the bent end of the side plate 55 can contact or separate from the surface of the mounting base plate 56 or the second base plate 65. The side plate 55 is used to enhance the lateral structural stiffness of the first elastic member 54, preventing it from shifting or bending laterally under the impact of the UAV 40 during takeoff and landing, ensuring that the first elastic member 54 always deforms in the vertical direction to accurately absorb the impact force, and avoiding the tilting of the takeoff and landing plate 51 due to the shift of the first elastic member 54, which would affect the takeoff and landing safety of the UAV 40. The downward bending of at least one end of the side plate 55 allows the bent end to contact the surface of the mounting base plate 56 or the second base plate 65 when the first elastic member 54 is deformed by impact, forming a limiting structure for the deformation of the first elastic member 54 and preventing the first elastic member 54 from being over-compressed.

[0045] The edge of the vehicle body 10 is equipped with a guard bar 14. This is used to physically prevent the drone 40 from accidentally sliding out of the vehicle body 10 during take-off and landing or when the vehicle body 10 is moving, thus preventing the drone 40 from falling due to vibration, wind interference, or operational deviation.

[0046] A limiting component 20 is provided on the vehicle body 10 on one side of the mounting slot 15. The limiting component 20 has a vertically arranged support column 21, and a first groove 22 is vertically opened on one side of the support column 21. A movable block capable of displacement is built into the first groove 22. The movable block is hinged to a first limiting rod 23. A second limiting rod 24 is hinged to the end of the first limiting rod 23. A pressure block 25 is provided at the end of the second limiting rod 24. The vertically arranged support column 21 provides support for the entire limiting assembly 20, preventing the limiting assembly 20 from tipping over due to force when fixing the drone. The first groove 22 vertically opened on one side of the support column 21 provides a directional displacement channel for the built-in moving block. The limiting height can be changed by adjusting the position of the moving block to adapt to drones with different body heights. The first limiting rod 23 hinged to the moving block and the second limiting rod 24 hinged to the end of the first limiting rod 23 can flexibly adjust the angle with the help of the double hinge structure, so that the pressure block 25 at the end of the second limiting rod 24 can fit against the upper part of the drone to avoid hard contact damage to the body. The pressure block 25 is used to fix the drone and prevent the drone from shifting or slipping due to the movement of the body 10 or external wind force.

[0047] The pressure block 25 can form a contact or separation relationship with the upper part of the drone 40 resting on the take-off and landing platform 50. The pressure block 25 can be an elastic element, a magnetic element, or a structural element with an adhesive function on its bottom surface. The first groove 22 is provided with a slot, and the moving block has a flexible locking block that cooperates with the slot, so that the position of the moving block relative to the first groove 22 can be controlled under the action of external force and kept in the target position.

[0048] In another embodiment, the movable block is the ball nut in the ball screw. The screw that mates with the ball nut is built into the first groove 22, and a power motor is provided at the end of the screw. The power motor is located at the upper or lower end of the support column 21. The power motor can control the rotation of the screw to drive the displacement of the ball nut, thereby driving the displacement of the first limit rod 23 and the second limit rod 24, so as to drive the pressure block 25 and the buffer assembly 30 to limit or cancel the limit operation of the UAV 40.

[0049] Example 2:

[0050] In this embodiment, see Appendix Figure 1 As shown, the vehicle body 10 has wheels for moving the vehicle body 10. At the front of the vehicle body 10 is a front end 11, on which a sensor 12 is provided for detecting road obstacles. The front end 11 is also provided with a light body 13 for sound and light alarms and displaying the location of the device.

[0051] The wheels on the vehicle body 10 provide a basis for its movement, and the front of the vehicle body 10, the front 11, provides a stable mounting carrier for the sensor 12 and the light body 13. The sensor 12 on the front 11 can detect obstacles in real time to prevent the vehicle body 10 from colliding with obstacles when it moves, thereby protecting the vehicle body 10 and key structures such as the adjustment component 60 in the mounting slot 15 and the take-off and landing platform 50 on top from impact damage. The light body 13 on the front 11 reminds the surrounding personnel and equipment to maintain a safe distance through audible and visual alarms, while clearly displaying the location of the facility, which makes it easier for the drone to accurately identify the take-off and landing area in low visibility environment and improve the accuracy of take-off and landing.

[0052] The front of the vehicle is equipped with a signal transceiver, a positioning sensor, a detachable power module, a control module, etc., to realize the movement control, position transmission and positioning of the entire equipment.

[0053] The rear of the vehicle body 10 has a tow hook, which is used to connect with an external trailer to increase the loading capacity during the drone logistics delivery process and meet functional requirements.

[0054] Example 3:

[0055] In this embodiment, a snap-fit ​​plate 58 is connected to the bottom surface of the end of the first connecting pipe 53 adjacent to the landing plate 51. The snap-fit ​​plate 58 is a flexible bent plate and can contact or separate from the surface of the first connecting pipe 53.

[0056] When the snap-fit ​​plate 58 contacts the surface of the first connecting tube 53, it can provide auxiliary fixation for the landing plate 51, which can limit the lateral displacement of the landing plate 51 relative to the supporting base plate 52 when the UAV 40 takes off or lands and impacts or when the adjustment component 60 adjusts the horizontal angle. This ensures the positional stability of the landing plate 51 when it carries the UAV 40 and avoids uneven stress on the landing gear of the UAV 40 due to plate offset. At the same time, the flexible material can buffer the slight collision between the landing plate 51 and the first connecting tube 53, reduce the wear of components caused by hard friction, and extend the service life of the landing module.

[0057] Example 4:

[0058] In this embodiment, the bottom surfaces of both ends of the landing plate 51 are connected to snap-fit ​​plates 58, which can contact or separate from the surfaces of the first connecting pipe 53 and the second connecting pipe 57.

[0059] The snap-fit ​​plates 58 connected to the bottom surfaces of both ends of the landing plate 51 form a bidirectional auxiliary fixation from both sides of the landing plate 51. This effectively limits the lateral displacement of the landing plate 51 relative to the supporting base plate 52 when the UAV 40 is impacted during take-off and landing or when the adjustment component 60 adjusts the horizontal angle. This ensures the positional stability of the landing plate 51 when it carries the UAV 40 and avoids uneven stress on the landing gear of the UAV 40 due to plate offset. At the same time, the flexible characteristics of the snap-fit ​​plates 58 can buffer the slight collisions between the landing plate 51 and the first connecting pipe 53 and the second connecting pipe 57, reduce the wear of components caused by hard friction, and extend the service life of the landing module.

[0060] Example 5:

[0061] In this embodiment, see Appendix Figure 1 Appendix Figure 7 and appendix Figure 8 As shown, a buffer assembly 30 is connected to the bottom of the pressure block 25, which is in contact with or separate from the upper end of the drone 40. The buffer assembly 30 includes a first buffer plate 31 and a second buffer plate 34 arranged at intervals. The first buffer plate 31 is connected to the pressure block 25, and the second buffer plate 34 is in contact with or separate from the upper part of the drone 40. Elastic strips 32 are provided on the opposite surfaces at the edges of the first buffer plate 31 and the second buffer plate 34. Springs 33 are threaded through the elastic strips 32 of the first buffer plate 31 and the second buffer plate 34. The axis of the springs 33 is parallel to the buffer strips 32 of the first buffer plate 31 and the second buffer plate 34. The body of the springs 33 passes through the buffer strips 32 of the upper and lower first buffer plates 31 and the second buffer plate 34 in sequence.

[0062] The first buffer plate 31 and the second buffer plate 34, which are spaced apart vertically, prevent the pressure block 25 from making direct hard contact with the drone 40. The elastic strips 32 on the opposite sides of the edges of the first buffer plate 31 and the second buffer plate 34, in conjunction with the springs 33 that pass through the elastic strips 32 and whose axes are parallel to the elastic strips 32, can deform when the second buffer plate 34 contacts the drone 40, absorbing the contact impact force when the pressure block 25 fixes the drone 40, reducing damage to the drone 40's fuselage and the cargo it carries. At the same time, the parallel cooperation between the spring 33 and the elastic strip 32 can maintain the structural stability of the buffer assembly 30, prevent the assembly from shifting during the buffering process, and ensure a uniform buffering effect. Furthermore, the buffer assembly 30 can be flexibly separated from the drone 40 along with the pressure block 25 without interfering with the drone 40's take-off and landing.
