[0014] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] An embodiment of this utility model provides a tandem drone transport trailer, such as... Figure 1-3 As shown, the system includes: a main frame assembly, with a tow rod 2 rotatably connected via a connector assembly 1; rollers are located at the bottom of the main frame assembly; a first fixing assembly 3 and two second fixing assemblies 4 are respectively fitted onto the front and rear wheels of the UAV on the main frame assembly; the main frame assembly includes a frame 5, with a triangular connecting frame 6 connected to the frame 5; the first fixing assembly 3 is located on the connecting frame 6, and the second fixing assemblies 4 are located on the frame 5; the connecting frame 6 is connected to the connector assembly 1; the tow rod 2 is connected to a tow head 8 via a coupling 7; the tow head 8 has a positioning hole 9, and a positioning pin 10 is installed in the positioning hole 9; a through hole 11 is provided on the side wall of the frame 5 away from the connecting frame 6, which is fitted onto the tow head 8; three rollers are included, one of which is connected below the connector assembly 1, and the other two rollers are respectively connected to both sides of the frame 5 via positioning frames 16. The positioning pin 10 can be a quick-release pin. The first fixed component 3 includes a sliding rail 31, one end of which is fixed to the connecting frame 6 and the other end is fixed to the frame 5. The front wheel can move along the sliding rail 31. A first wide band 32 is connected to the sliding rail 31. A gap is formed between the end of the sliding rail 31 and the frame 5.

[0017] In this embodiment, a main frame assembly is formed by a frame 5 and a triangular connecting frame 6. A first fixing component 3 for fixing the front wheel of the drone is set on the connecting frame 6, and two second fixing components 4 for fixing the rear wheel of the drone are set on the frame 5. The structure is simple, lightweight and reliable, and can be used as a temporary storage and parking device for drones. A sliding track 31 is set on the main frame assembly, which not only positions the front wheel of the drone, but also facilitates the movement of the drone without the need for external force to carry it, saving time and effort. Multiple transfer trailers can be connected in series by the cooperation of the towing head 8 in two adjacent transfer trailers and the through hole 11 on the frame 5 (as a towing port), thereby improving the transfer efficiency of drones.

[0018] For example, the first wide strap 32 is vertically mounted on the sliding rail 31, with one end fixed to the sliding rail 31 and the other end movably connected to the sliding rail 31 via a connector. In use, the first wide strap 32 secures the front wheel of the drone. The first wide strap 32 is an adjustable-length webbing. The connector can be a conventional snap-fit ​​joint, including quick-locking and anti-loosening mechanisms, or other structures, as long as a connection is achieved; details are omitted here. Additionally, the end of the sliding rail 31 is connected to the frame 5 via two baffles 33. The two baffles 33 are V-shaped, forming a gap between them, allowing the towing head 8 of another transport trailer to penetrate into this gap and be positioned by a positioning pin 10 to prevent it from falling off during transport. To increase the stability of the connecting frame 6, a structural support reinforcement 13 is connected at the centerline of the connecting frame 6, and the sliding rail 31 is fixed above the structural support reinforcement 13. The coupling 7 includes a first rotating shaft and a second rotating shaft arranged perpendicularly to each other, used to achieve multi-degree-of-freedom steering of the rear vehicle relative to the front vehicle.

[0019] Furthermore, the method for connecting multiple transfer trailers in series is as follows: for two transfer trailers connected in series, the transfer trailer located in front is designated as the first transfer trailer, and the other is designated as the second transfer trailer; the towing head 8 of the second transfer trailer is inserted into the gap along the through hole 11 of the first transfer trailer, and the positioning hole 9 is located in the gap, and the positioning pin 10 is inserted into the positioning hole 9 to realize the series connection.

[0020] Furthermore, such as Figure 4 As shown, the second fixing component 4 includes a rear wheel mounting plate 41 and a second wide strap 42. The rear wheel mounting plate 41 is fixed to the frame 5, and a wheel stop mechanism 43 is provided on the rear wheel mounting plate 41. One end of the second wide strap 42 is fixed to the rear wheel mounting plate 41, and the other end is movably connected to the wheel stop mechanism 43 through a connector. The wheel stop mechanism 43 has an arc surface adapted to the wheel, which forms a space with the wide strap for positioning the wheel. The second wide strap 42 is an adjustable-length webbing. The connector can be a conventional snap-fit ​​joint, including a quick-lock and anti-loosening mechanism, or other structures, as long as a connection can be achieved; details will not be elaborated here. The second fixing component 4 prevents the rear wheel of the drone from moving on the frame 5, ensuring the safe transport of the drone.

[0021] In an exemplary embodiment, the main frame assembly further includes a first connecting rod 14, which is vertically connected to the connecting frame 6 away from the frame 5. A second connecting rod 15 is vertically connected to the first connecting rod 14 and is rotatably connected to the joint assembly 1. The horizontal plane of the second connecting rod 15 is higher than the horizontal plane of the connecting frame 6. The positioning frame 16 includes a connecting plate 161, one side of which is connected to the frame 5, forming an obtuse angle with the frame 5. A cover plate 162 is connected to the other side, which is parallel to the frame 5. Rollers are connected below the cover plate 162. The front end of the sliding track 31 abuts against the first connecting rod 14.

[0022] In this embodiment, one roller is fixed by the connector assembly 1, and the other two rollers are fixed by the positioning frame 16, ensuring that the three rollers are on the same horizontal plane and enabling the movement of the transport trailer; the front end of the sliding track 31 abuts against the first connecting rod 14, which can further limit the front wheel of the drone and prevent the drone from moving towards the traction rod 2.

[0023] In another exemplary embodiment, three ramp plates 17 are movably connected to the side of frame 5 away from connecting frame 6. The three ramp plates 17 respectively engage with two rear wheel mounting plates 41 and sliding rails 31. During drone transport, the front and rear of the drone move onto frame 5 via the three ramp plates 17. The width of the ramp plates 17 is the same as the width of frame 5. After use, as... Figure 5 As shown, the slope plate 17 can be placed in the hollow position of the frame 5, that is, between the sliding track 31 and the two rear wheel mounting plates 41, which makes it easy to store and saves space.

[0024] The connector assembly 1 includes a base plate 101, a U-shaped connector 102, and two clamping plates 103. A rotating shaft 104 is rotatably connected to the upper surface of the base plate 101, and rollers are rotatably connected to its lower surface via two connecting plates 161. The rotating shaft 104 passes through both side walls of the U-shaped connector 102. The two clamping plates 103 are located between the side walls of the U-shaped connector 102, clamping the rotating shaft 104 and securing it with bolts passing through both clamping plates 103 and the rotating shaft 104. The closed end of the U-shaped connector 102 is connected to the main frame assembly (second connecting rod 15). The two clamping plates 103 are connected to the traction rod 2 via quick-release pins. Specifically, the quick-release pins pass through both clamping plates 103 and the traction rod 2, providing a detachable connection. In use, the rotating shaft 104 allows for flexible control of the direction of the main frame assembly during transport, preventing damage caused by a rigid connection between the traction rod 2 and the second connecting rod 15.

[0025] The implementation method of this utility model of a tandem drone transport trailer is as follows: S100, the preparation steps for unfolding the transfer trailer include: S101, assemble and connect the traction rod 2 to the main frame assembly.
