Detailed Implementation

[0044] 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.

[0045] An embodiment of the present invention, a tool-free unmanned aerial vehicle trailer, is as follows: Figure 1 As shown, it includes: a frame assembly 1, a handlebar assembly 2, and two telescopic assemblies 3. The bottom of the frame assembly 1 is provided with a roller assembly; the handlebar assembly 2 is located at the front end of the frame assembly 1; the fixed ends of the two telescopic assemblies 3 are rotatably connected to the frame assembly 1, and the frame assembly 1 is provided with a limiting assembly to restrict the rotation of the telescopic assemblies 3. The output end of the telescopic assemblies 3 is connected to a support assembly 4; wherein, the support assembly 4 is provided with a shock-absorbing structure, and the support assembly 4 is used to support the wing.

[0046] For example, in one specific embodiment, the telescopic component 3 includes: a sleeve 31, a telescopic tube 41, and a positioning pin, such as... Figure 1 and Figure 4 As shown, one end of the sleeve 31 is rotatably connected to the frame assembly 1 via a hinge 33, and a plurality of first positioning holes 32 are provided on the wall of the sleeve 31 along its length; as shown Figure 1 and Figure 5As shown, the telescopic tube 41 is slidably fitted inside the sleeve 31, and the support component 4 is disposed at the end of the telescopic tube 41 opposite to the sleeve 31. Multiple second positioning holes 46 are provided on the tube wall along the length of the telescopic tube 41. Positioning pins are used to connect the first positioning holes 32 of the sleeve 31 and the second positioning holes 46 of the telescopic tube 4. It should be noted that in this embodiment, the telescopic tube 41 is made of an aluminum alloy rectangular tube, and its external dimensions are the same as the internal dimensions of the sleeve 31. The telescopic tube 41 can slide inside the sleeve 31. Three equally spaced second positioning holes 46 are designed on the side of the telescopic tube 41. The size and distance of the lifting pin holes 46 are consistent with the three first positioning holes 32 of the sleeve 31. The height of the support component 4 can be adjusted by the cooperation of the positioning pins with different first positioning holes 32 and second positioning holes 46.

[0047] For example, such as Figure 2 and Figure 4 As shown, in one specific embodiment, the limiting component includes: a limiting lug 17 and a quick-release pin. The limiting lug 17 is disposed on the top of the frame assembly 1 on both sides of the sleeve 31, and a first limiting hole is provided on the limiting lug 17; a second limiting hole 34 is provided on the lower wall of the sleeve 31, and the quick-release pin is used to connect the first limiting hole of the limiting lug 17 and the second limiting hole 34 on the sleeve 31. It should be noted that, as Figure 2 As shown, two limiting lugs 17 are respectively installed on the top of the middle part of the frame 11 of the frame assembly 1. The limiting lugs 17 are L-shaped, and the lower end plate of the L-shaped part is fixedly connected to the frame 11. The upper and lower end plates of the L-shaped part are designed with first limiting holes. In use, the limiting lugs 17 and the sleeves 31 can be connected by passing a quick-release pin through the first limiting hole of the limiting lug 17 and the second limiting hole 34 on the sleeve 31, thereby fixing the sleeve 31 in a vertical position. At this time, the drone's wings can be placed on the support assembly 4. When the drone trailer is to be folded away, simply remove the quick-release pin, and the two sleeves 31 can be folded inward for storage, thereby reducing the space occupied.

[0048] For example, such as Figure 5As shown, in one specific embodiment, the support component 4 includes: a horizontal tube 42, a wing support body 43, and a nylon fastening strap 45. The horizontal tube 42 is horizontally disposed at the end of the telescopic tube 4; the wing support body 43 is disposed at the top of the horizontal tube 42, and the side of the wing support body 43 facing away from the horizontal tube 42 is fitted with the outer surface of the wing; the nylon fastening strap 45 is used to secure the wing placed on the wing support body 43; the support component 4 also includes: a foam pad 44, which is disposed on the side of the wing support body 43 that is fitted with the outer surface of the wing. In this embodiment, the horizontal tube 42 is made of aluminum alloy rectangular tube, and the wing support body 43 is made of plastic. The lower part of the wing support body 43 is connected to the top of the horizontal tube 42, and the top shape of the wing support body 43 is made according to the wing profile. Therefore, for different models of drones, only the wing support body 43 needs to be replaced, which improves the versatility and utilization of the drone trailer. Foam pads 44 are placed on the upper surface of the wing support 43 to provide cushioning and shock absorption. The ends of nylon fastening straps 45 are connected to the front and rear ends of the wing support 43 respectively. When the drone wing is placed on the wing support 43, the drone wing is fastened by the nylon fastening straps 45 to fix the drone and prevent it from falling off.

[0049] For example, such as Figure 2 As shown, in one specific embodiment, the frame assembly 1 includes a frame 11, a base plate 12, and a connecting beam. The frame 11 includes a tripod and a square frame, with one side of the tripod connected to the square frame. The base plate 12 is connected to the tripod and the square frame. One end of the connecting beam is connected to a corner of the tripod away from the square frame, and the handle assembly 2 is connected to the other end of the connecting beam. In this embodiment, the frame 11 is welded from aluminum alloy rectangular tubing, resulting in a lightweight and low-cost design. The base plate 12 is located below the frame 11, and the base plate 12 is connected to the frame 11 by riveting or welding. The base plate 12 and the frame 11 form a storage area for storing drone maintenance tools.

[0050] For example, such as Figure 6 and Figure 7 As shown, in one specific embodiment, the roller assembly includes: a front wheel assembly 5 and two rear wheel assemblies 6. The front wheel assembly 5 includes: a front wheel strut 51, one end of which is connected to a connecting beam of the frame assembly 1; and a horizontally arranged front wheel axle 52, the other end of which is connected to the front wheel strut 51. A front wheel 53 is rotatably connected to the front wheel axle 52 via a bearing, and the front wheel axle 52 is provided with a bearing retaining ring 54. A locking nut 55 is provided at the end of the front wheel axle 52. Figure 2In the enlarged view at point A, the connecting beam has a front wheel mounting pin hole 19 in the vertical direction. The front wheel mounting pin hole 19 is used to connect the front wheel strut 51 of the front wheel assembly 5. After the front wheel strut 51 passes through the front wheel mounting pin hole 19, it is limited by the front wheel strut pin hole 56 on the front wheel strut 51 and the front wheel quick-release pin. Figure 6 As shown, a shoulder 57 is provided in the middle of the front wheel strut 51. The shoulder 57 is used to limit the length of the front wheel strut 51 that passes through the front wheel mounting pin hole 19. A connecting lug is provided at the bottom of the front wheel strut 51, and a front wheel axle mounting hole 58 for mounting the front wheel axle 52 is provided on the connecting lug. The rear wheel assembly 6 includes: a rear wheel axle 16 horizontally provided at the bottom of the base plate 12, and a rear wheel 61 rotatably connected to the rear wheel axle 16. It should be noted that, as Figure 2 As shown, a first rear wheel mounting seat 13 and a second rear wheel mounting seat 14 are installed on both sides of the rear part of the base plate 12. A rear wheel axle sleeve 15 is fixedly connected inside the first rear wheel mounting seat 13 and the second rear wheel mounting seat 14. A rear wheel axle 16 is fixedly fitted inside the rear wheel axle sleeve 15. The rear wheel axle 16 is used to install the rear wheel 61. A rear wheel washer 63 is installed at the end of the rear wheel axle 16 that protrudes from the rear wheel 61. The rear wheel axle 16 is also provided with a rear wheel quick-release pin 62 to prevent the rear wheel washer 63 from dislodging. That is, the rear wheel quick-release pin 62 can be used to restrict the axial movement of the rear wheel 61 on the rear wheel axle 16.

[0051] For example, such as Figure 3 As shown, in one specific embodiment, the handle assembly 2 includes: a handle support tube 21, which is made of aluminum alloy rectangular tubing. One end of the handle support tube 21 is connected to a handle 22, and a rubber sleeve 23 is provided on the handle 22. The other end of the handle support tube 21 is connected to an adapter plate 24. The adapter plate 24 is connected to a connecting beam at the end opposite to the handle support tube 21. Meanwhile, as shown... Figure 2 In the enlarged view at point A, the side of the connecting beam is designed with two handle mounting pin holes 18. The handle mounting pin holes 18 are used to connect the adapter plate 24 of the handle assembly 2. The adapter plate 24 is provided with adapter plate pin holes 25. The adapter plate 24 and the connecting beam are connected by passing a pin through the adapter plate pin holes 25.

[0052] Working principle

[0053] When the drone is being supported, the sleeve 31 is rotated to make it vertical. At this time, the first limiting hole of the limiting lug 17 and the second limiting hole 34 on the sleeve 31 are connected by the quick-release pin to limit the sleeve 31 of the telescopic component 3. Then, by adjusting the length of the telescopic component 3, i.e., by removing the positioning pin, the length of the telescopic tube 41 inside the sleeve 31 is adjusted to adjust the height of the support component 4 so that the height of the support component 4 is adapted to the support of the drone wing. Then, the first positioning hole 32 of the sleeve 31 and the second positioning hole 46 of the telescopic tube 4 are connected by the positioning pin to lock the length of the telescopic component 3 in the vertical direction, and then the drone wing can be placed.

[0054] When the drone trailer is being retrieved, the front wheel assembly 1 can be disassembled by removing the quick-release pin connecting the front wheel strut 51 of the front wheel assembly 5 to the connecting beam 1; the handle assembly 1 can be disassembled by removing the quick-release pin connecting the handle assembly 2 to the connecting beam; the rear wheel assembly 6 can be disassembled by removing the quick-release pin connecting the rear wheel assembly 6 to the rear wheel axle 16; and the sleeve 31 can be folded inward by removing the quick-release pin connecting the sleeve 31 to the upper limit lug 17 of the frame 11. The entire retrieval operation is tool-free and very convenient and quick.
