Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) cargo carrying, in particular to an anti-dropping mechanism for a UAV hanging basket. Background Art

[0002] When a UAV is used for logistics distribution, it is crucial to ensure the connection stability and safety between the UAV and the cargo hanging basket during flight. In the existing UAV cargo-carrying system, the UAV and the cargo hanging basket are usually connected by means of connection methods such as suspension ropes and robotic arm grasping. Among them, the connection method of suspension ropes is simple and has a high connection strength, but it lacks convenience when loading and unloading goods. Although the connection method of robotic arm grasping can achieve flexible loading and unloading and transportation of goods, the coupling relationship between the robotic arm and the UAV is complex, which requires high stability and control accuracy of the UAV, and is prone to the problem of the hanging basket falling off due to the influence of the external environment. Therefore, designing an anti-dropping mechanism that can improve the connection stability and portability between the UAV and the hanging basket at the same time is a technical problem that enterprise R & D personnel urgently need to solve. Content of the Utility Model

[0003] In view of the above deficiencies in the prior art, the present application provides an anti-dropping mechanism for a UAV hanging basket.

[0004] The above-mentioned invention object of the present application is achieved through the following technical solutions:

[0005] A UAV main body, a guiding shaft is arranged at the bottom of the UAV main body, and a positioning rod is arranged outside the guiding shaft;

[0006] An installation sleeve for plugging and cooperating with the guiding shaft, one end of the installation sleeve is open and the other end is closed, the closed end of the installation sleeve is fixedly connected to the cargo hanging basket, a first sliding groove is opened at the end of the open end of the installation sleeve along its own length direction, a second sliding groove is communicated with the first sliding groove, both the first sliding groove and the second sliding groove are used for the positioning rod to pass through, the second sliding groove is also used for providing vertical support for the positioning rod, and a limiting groove is communicated with one side of the second sliding groove close to the open end of the installation sleeve.

[0007] By adopting the above technical solution, during installation, the UAV body drives the guiding shaft to move to the installation sleeve. While completing the insertion and fitting of the guiding shaft and the installation sleeve, the positioning rod is buckled into the first sliding groove, and then buckled to the limiting groove via the second sliding groove to complete the connection between the UAV and the cargo hanging basket. When it is necessary to disconnect, under the drive of the UAV, by rotating and moving, the positioning rod is disengaged from the first sliding groove, and then the disconnection of the cargo hanging basket can be completed, which can greatly improve the connection portability between the UAV and the cargo hanging basket. And during this process, the first sliding groove and the second sliding groove provide a through path for the positioning rod to move inside the outer wall of the installation sleeve, so that the positioning rod can slide to the limiting groove by rotating and moving under the drive of the UAV. After the positioning rod reaches the limiting groove, under the action of the self-weight of the cargo hanging basket, the limiting groove can continuously abut against the positioning rod, thereby improving the connection stability between the UAV and the cargo hanging basket.

[0008] In a preferred example of the present application, it can be further configured that: an elastic member is provided between the guiding shaft and the installation sleeve, and when the positioning rod is located in the limiting groove, the elastic member is used to apply a thrust along the length direction of the guiding shaft to the guiding shaft.

[0009] By adopting the above technical solution, when the positioning rod is located in the limiting groove, by providing an elastic member to apply a thrust along the length direction of the guiding shaft to the guiding shaft, the guiding shaft can drive the positioning rod to continuously abut upward against the inside of the limiting groove, further improving the connection stability between the UAV and the cargo hanging basket.

[0010] In a preferred example of the present application, it can be further configured that: the elastic member is a spring.

[0011] By adopting the above technical solution, when the guiding shaft is inserted and fitted with the installation sleeve, the spring abuts against the inner bottom of the installation sleeve, making the spring in a compressed state. After the positioning member is slid to the limiting groove, the spring can apply an elastic restoring force along the length direction of the guiding shaft to the installation sleeve, so that the positioning rod continuously abuts against the limiting groove under the push of the thrust, thereby realizing the improvement of the connection stability between the UAV and the cargo hanging basket.

[0012] In a preferred example of the present application, it can be further configured that: a guiding sleeve is extended at the open end of the installation sleeve, and the shape of the guiding sleeve is trumpet-shaped.

[0013] By adopting the above technical solution, by providing a guiding sleeve with a trumpet shape, it is convenient to position the guiding shaft inside the installation sleeve, thereby improving the connection efficiency between the UAV and the cargo hanging basket.

[0014] In a preferred example of the present application, it can be further configured that: the size of the limiting groove is adapted to the size of the positioning rod.

[0015] By adopting the above technical solution, the possibility of the positioning rod shaking when it is located inside the limiting groove can be reduced.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. During installation, the drone body drives the guiding shaft to move to the installation sleeve. While completing the insertion and cooperation of the guiding shaft and the installation sleeve, the positioning rod is buckled into the first sliding groove, and then buckled to the limiting groove via the second sliding groove to complete the connection between the drone and the cargo hanging basket. When it is necessary to disconnect, under the drive of the drone, by rotating and moving, after the positioning rod is disengaged from the first sliding groove, the disconnection of the cargo hanging basket can be completed, which can greatly improve the connection portability between the drone and the cargo hanging basket. And during this process, the first sliding groove and the second sliding groove provide a through path for the positioning rod to move inside the outer wall of the installation sleeve, so that the positioning rod can slide to the limiting groove by rotating and moving under the drive of the drone. After the positioning rod reaches the limiting groove, under the action of the self-weight of the cargo hanging basket, the limiting groove can continuously abut against the positioning rod, thereby improving the connection stability between the drone and the cargo hanging basket.

[0018] 2. When the guiding shaft is inserted and cooperated with the installation sleeve, the spring abuts against the inner bottom of the installation sleeve, so that the spring is in a compressed state. After the positioning member is slid to the limiting groove, the spring can apply an elastic restoring force along the length direction of the guiding shaft to the installation sleeve, so that the positioning rod continuously abuts against the limiting groove under the push of the thrust, thereby realizing the improvement of the connection stability between the drone and the cargo hanging basket.

[0019] 3. By providing a guiding sleeve with a horn-shaped shape, it is convenient to position the guiding shaft inside the installation sleeve, thereby improving the connection efficiency between the drone and the cargo hanging basket. Description of the Drawings

[0026] In addition, the term "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after, unless otherwise specified.

[0027] A drone hanging basket anti-detachment mechanism of the present application will be described below with reference to the accompanying drawings.

[0028] Refer to Figures 1 to 3 , wherein, as Figure 1 and Figure 2As shown in the figure, the anti-detachment mechanism of the drone hanging basket includes the drone main body 1. A guiding shaft 2 is arranged at the bottom of the drone main body 1. A positioning rod 3 is arranged outside the guiding shaft 2. And it includes an installation sleeve 4 for plugging and cooperating with the guiding shaft 2. One end of the installation sleeve 4 is open and the other end is closed. The closed end of the installation sleeve 4 is fixedly connected to the cargo hanging basket 5. A first sliding groove 6 is opened at the end of the open end of the installation sleeve 4 along its own length direction. A second sliding groove 7 is communicated with the first sliding groove 6. Both the first sliding groove 6 and the second sliding groove 7 are used for the positioning rod 3 to pass through. The second sliding groove 7 is also used to provide vertical support for the positioning rod 3. One side of the second sliding groove 7 close to the open end of the installation sleeve 4 is communicated with a limiting groove 8. During installation, the drone main body 1 drives the guiding shaft 2 to move to the installation sleeve 4. While completing the plugging and cooperation between the guiding shaft 2 and the installation sleeve 4, the positioning rod 3 is buckled into the first sliding groove 6, and then buckled to the limiting groove 8 via the second sliding groove 7 to complete the connection between the drone and the cargo hanging basket 5. When it is necessary to disconnect the connection, only under the drive of the drone, by rotating and moving, after the positioning rod 3 disengages from the first sliding groove 6, the disconnection of the cargo hanging basket 5 can be completed, which can greatly improve the connection portability between the drone and the cargo hanging basket 5. And in this process, the first sliding groove 6 and the second sliding groove 7 provide a through path for the positioning rod 3 to move inside the outer wall of the installation sleeve 4, so that the positioning rod 3 can slide to the limiting groove 8 by rotating and moving under the drive of the drone. After the positioning rod 3 reaches the limiting groove 8, under the action of the self-weight of the cargo hanging basket 5, the limiting groove 8 can continuously abut against the positioning rod 3, thereby improving the connection stability between the drone and the cargo hanging basket 5.

[0029] Further, as Figure 3 shown, an elastic member is arranged between the guiding shaft 2 and the installation sleeve 4. When the positioning rod 3 is located in the limiting groove 8, the elastic member is used to apply a thrust force along the length direction of the guiding shaft 2 to the guiding shaft 2. When the positioning rod 3 is located in the limiting groove 8, by setting the elastic member to provide a thrust force along the length direction of the guiding shaft 2 to the guiding shaft 2, the guiding shaft 2 can drive the positioning rod 3 to continuously abut against the inside of the limiting groove 8 upwards, further improving the connection stability between the drone and the cargo hanging basket 5.

[0030] Specifically, the elastic member is a spring 9. When the guiding shaft 2 and the installation sleeve 4 are plugged and cooperated, the spring 9 abuts against the inner bottom of the installation sleeve 4, so that the spring 9 is in a compressed state. After the positioning member slides to the limiting groove 8, the spring 9 can apply an elastic restoring force along the length direction of the guiding shaft 2 to the installation sleeve 4, so that the positioning rod 3 continuously abuts against the limiting groove 8 under the push of the thrust force, thereby realizing the improvement of the connection stability between the drone and the cargo hanging basket 5.

[0031] Further, as Figure 2 and Figure 3As shown in the figure, in order to improve the accuracy of the drone driving the guide shaft 2 to access the installation sleeve 4, a guide sleeve 10 is extended at the open end of the installation sleeve 4. The shape of the guide sleeve 10 is trumpet-shaped. By setting the guide sleeve 10 with a trumpet-shaped shape, it is convenient to position the guide shaft 2 inside the installation sleeve 4, thereby improving the connection efficiency between the drone and the cargo hanging basket 5.

[0032] In addition, in one embodiment, the size of the limit groove 8 is adapted to the size of the positioning rod 3, which can reduce the possibility of the positioning rod 3 shaking when it is located inside the limit groove 8.

[0033] The implementation principle of the anti-drop mechanism of the drone hanging basket in the embodiment of the present application is as follows: During installation, the drone body 1 drives the guide shaft 2 to move to the installation sleeve 4. While entering the installation sleeve 4 under the guiding action of the guide sleeve 10, the positioning rod 3 is buckled into the first sliding groove 6 and then buckled into the limit groove 8 via the second sliding groove 7. At this time, the spring 9 abuts against the inner bottom of the installation sleeve 4 and applies an elastic restoring force to the installation sleeve 4, so that the positioning rod 3 continuously abuts against the limit groove 8, completing the connection between the drone and the cargo hanging basket 5. When it is necessary to disconnect the connection, first place the cargo hanging basket 5 on the ground to obtain ground support, and then under the drive of the drone, make the positioning rod 3 disengage from the limit groove 8 along the length direction of the limit groove 8, and cooperate with the rotation and movement to make the positioning rod 3 disengage from the first sliding groove 6, and then the disconnection of the cargo hanging basket 5 can be completed.

[0034] It should be noted that multiple anti-drop mechanisms of the drone hanging basket of the present application can be provided between several drone bodies 1 and the cargo hanging basket 5 to meet the requirements when the load capacity is larger, that is, the guide shafts 2 at the bottoms of several drone bodies 1 can be respectively inserted and matched with several installation sleeves 4 provided on the cargo hanging basket 5 to complete the connection between several drones and the cargo hanging basket 5, so as to cope with the situation of larger load capacity.

[0035] The above specific implementation manners do not constitute a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
