Description

Technical Field

[0001] This utility model relates to the field of drone technology, specifically to a drone express cabinet and its drone positioning component. Background Technology

[0002] Unmanned aerial vehicle (UAV) express refers to the use of unmanned, low-altitude aircraft controlled by radio remote control equipment and onboard program control devices to carry packages and automatically deliver them to their destinations. Its main advantages are solving delivery problems in remote areas, improving delivery efficiency, and reducing labor costs.

[0003] Currently, self-service parcel lockers used for drones typically have a docking platform for drones to land. The docking platform is equipped with positioning components to locate the drone in a designated position, thus facilitating subsequent pickup, unloading, and takeoff. Since drones are currently positioned at the same predetermined location after landing using drone positioning components, pickup, unloading, and takeoff are all achieved at the same predetermined location. However, when the pickup / unloading location is different from the takeoff location, the current drone positioning components cannot simultaneously meet the positioning requirements for both locations.

[0040] Please see Figures 1 to 4 One embodiment of this utility model provides a drone positioning component for a drone delivery locker, comprising:

[0041] Shutdown platform 10;

[0042] The centering mechanism 20 includes two centering push rods 21 and a centering drive assembly 22. The two centering push rods 21 are arranged side by side on the parking platform 10. The centering drive assembly 22 is driven to the two centering push rods 21. The two centering push rods 21 are configured to move away from each other to an avoidance position or move closer to each other to a guide position under the drive of the centering drive assembly 22. When the two centering push rods 21 move closer to each other to the guide position, a guide channel 211 is formed between the two centering push rods 21. The guide channel 211 can stably guide the UAV to move.

[0043] The first positioning mechanism 30 includes a first positioning push rod 31 and a first positioning drive assembly 32. The first positioning push rod 31 is movably mounted on the parking platform 10. The first positioning drive assembly 32 is drivenly connected to the first positioning push rod 31. The first positioning push rod 31 is configured to move along the guide direction of the guide channel 211 to the unloading position 11 under the drive of the first positioning drive assembly 32.

[0044] The second positioning mechanism 40 includes a second positioning push rod 41 and a second positioning drive assembly 42. The second positioning push rod 41 is movably mounted on the parking platform 10. The second positioning drive assembly 42 is drivenly connected to the second positioning push rod 41. The second positioning push rod 41 is configured to move along the guide direction of the guide channel 211 to the takeoff position 12 under the drive of the second positioning drive assembly 42.

[0045] The unloading position 11 and the takeoff position 12 are arranged sequentially along the guide direction of the guide channel 211. The unloading position 11 and the takeoff position 12 are both located between the first positioning push rod 31 and the second positioning push rod 41, so as to avoid the first positioning push rod 31 colliding with the second positioning push rod 41 when the first positioning push rod 31 pushes the drone, and to avoid the second positioning push rod 41 colliding with the first positioning push rod 31 when the second positioning push rod 41 pushes the drone.

[0046] In one embodiment, due to the limited structural layout of the drone delivery locker, the clamping module of the drone delivery locker can only reach the vicinity of the side of the landing platform 10, while the drone needs to take off from the center of the landing platform 10 to ensure relatively stable airflow around the drone during takeoff. Therefore, the drone needs to be positioned at different locations. Before the drone lands on the landing platform 10, the centering push rod 21 is in a clearance position. Then, the two centering push rods 21 move closer to each other until the centering push rod 21 moves to the guide position. The first positioning push rod 31 pushes the drone along the guide channel 211, so that the drone is stably pushed to the unloading position 11 under the guidance of the guide channel 211. Subsequently, the clamping module inside the drone delivery locker unloads the package from the drone or places the package on the drone. Then, the second positioning push rod 41 pushes the drone along the guide channel 211, so that the drone is stably pushed to the takeoff position 12 under the guidance of the guide channel 211.

[0047] In some optional embodiments, the stopping platform 10 is provided with multiple first slide rails 13, and the two ends of the centering push rod 21 are respectively slidably engaged with two of the first slide rails 13, thereby improving the movement stability of the centering push rod 21. The stopping platform 10 may be provided with only two first slide rails 13, with one end of each of the two centering push rods 21 slidably engaged with one of the first slide rails 13, and the other end of each of the two centering push rods 21 slidably engaged with the other first slide rail 13. In this embodiment, the stopping platform 10 is provided with four centering push rods 21, with the two ends of one centering push rod 21 respectively slidably engaged with two of the first slide rails 13, and the two ends of the other centering push rod 21 respectively slidably engaged with the other two first slide rails 13, but this example is not limited to this one.

[0048] In some alternative embodiments, guide plates 212 are provided on the side of each of the two centering push rods 21 facing each other. The guide plates 212 extend along the guiding direction of the guide channel 211 and are used to guide the UAV to move along the guide channel 211, which helps to improve the movement stability of the UAV.

[0049] Please see Figure 5 The specific structure of the centering drive assembly 22 can be selected according to actual needs. For example, in some optional embodiments, the centering drive assembly 22 includes two first linear motors 221, which are mounted on the stopping platform 10 and connected to the corresponding centering push rods 21 for driving, thereby enabling each centering push rod 21 to be driven independently, which facilitates the control of the centering push rods 21. Of course, the centering drive assembly 22 can also adopt other suitable translation drive assemblies, such as a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, or a cylinder translation drive assembly, etc., without limitation to this example.

[0050] In some alternative implementations, a parking area 14 is pre-set on the parking platform 10, and the loading / unloading position 11 and the take-off position 12 are both located within the parking area 14;

[0051] The first positioning drive component 32 is disposed on one side of the parking area 14. A first shielding plate 15 is disposed between the first positioning drive component 32 and the parking area 14. The first shielding plate 15 helps to conceal the first positioning drive component 32, improving aesthetics. Especially when the parking platform 10 is placed on the drone delivery locker, it can work with the locker shell to conceal the first positioning drive component 32, preventing it from being exposed and improving aesthetics. In addition, the first shielding plate 15 also helps to stabilize the airflow on the parking platform 10 when the drone takes off, preventing irregular turbulence on the parking platform 10 caused by the irregular shell of the first positioning drive component 32 and other components, which would affect the drone's takeoff.

[0052] In some optional embodiments, the parking platform 10 has a pre-set parking area 14, and the unloading position 11 and the takeoff position 12 are both located within the parking area 14. The second positioning drive component 42 is disposed on one side of the parking area 14, and a second shield 16 is disposed between the second positioning drive component 42 and the parking area 14. The second shield 16 helps to conceal the second positioning drive component 42, improving aesthetics. Especially when the parking platform 10 is placed on a drone delivery locker, it can work with the locker shell to conceal the second positioning drive component 42, preventing it from being exposed and improving aesthetics. In addition, the second shield 16 also helps to stabilize the airflow on the parking platform 10 when the drone takes off, preventing irregular turbulence on the parking platform 10 caused by the irregular shell of the second positioning drive component 42 and other components, which would affect the takeoff of the drone.

[0053] It should be noted that the positions and dimensions of the parking area 14, the cargo handling position 11, and the takeoff position 12 relative to the parking platform 10 can be selected according to actual needs, and are not limited to those shown in the illustration. Furthermore, the parking area 14, cargo handling position 11, and takeoff position 12 refer to specific positions relative to the parking platform 10. For easy identification and differentiation, these can be indicated on the parking platform 10 using indicators, symbols, or signals.

[0054] In some optional embodiments, the parking platform 10 is provided with two second slide rails 17 extending along the guide direction of the guide channel 211. The two ends of the first positioning push rod 31 are respectively slidably engaged with the two second slide rails 17, and the two ends of the second positioning push rod 41 are respectively slidably engaged with the two second slide rails 17. The first positioning push rod and the second positioning push rod 41 share the second slide rails 17, which helps to simplify the structure. The second positioning push rod 41, the unloading position 11, the take-off position 12 and the first positioning push rod 31 are arranged sequentially along the guide direction of the guide channel 211, which can also avoid the first positioning push rod 31 and the second positioning push rod 41 colliding with each other.

[0055] In some optional embodiments, two second slide rails 17 are respectively disposed between the stopping area 14 and the first baffle 15 and between the stopping area 14 and the second baffle 16; wherein, the first positioning push rod 31 is provided with a first adapter 311, the first adapter 311 is arranged above the first baffle 15, the first positioning drive assembly 32 is driven connected to the first positioning push rod 31 through the first adapter 311, the second positioning push rod 41 is provided with a second adapter 411, the second adapter 411 is arranged above the second baffle 16, the second positioning drive assembly 42 is driven connected to the second positioning push rod 41 through the second adapter 411. The first adapter 311 can pass over the first baffle 15, facilitating the transmission between the first positioning drive assembly 32 and the first positioning push rod 31. The second adapter 411 can pass over the second baffle 16, facilitating the transmission between the second positioning drive assembly 42 and the second positioning push rod 41. Alternatively, in other embodiments, through slots can be provided on the first baffle 15 and the second baffle 16, with the first adapter 311 passing through the through slot on the first baffle 15 and then connecting to the first positioning drive assembly 32, and the second adapter 411 passing through the through slot on the second baffle 16 and then connecting to the second positioning drive assembly 42. This is not a limitation. The arrangement of the second slide rail 17 is not limited to between the stopping area 14 and the first baffle 15, or between the stopping area 14 and the second baffle 16; it can be arranged in other suitable locations.

[0056] The specific structures of the first positioning drive assembly 32 and the second positioning drive assembly 42 can be selected according to actual needs. For example, in some optional embodiments, the first positioning drive assembly 32 is a second linear motor mounted on the stopping platform 10, and the second linear motor is drivenly connected to the first positioning push rod 31; and / or, the second positioning drive assembly 42 is a third linear motor mounted on the stopping platform 10, and the third linear motor is drivenly connected to the second positioning push rod 41. Of course, the first positioning drive assembly 32 and the second positioning drive assembly 42 can also be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, or a cylinder translation drive assembly, etc., and are not limited to this example.
