Based on Example 2, this embodiment provides an auxiliary sliding component 9 for assisting the lateral telescopic component 5, the purpose of which is to assist the lateral telescopic component 5 to extend the load-carrying storage box 6 out of the hovering range of the drone. The specific structure of the auxiliary sliding component 9 in this embodiment will be described in detail below.

[0066] An auxiliary sliding assembly 9 installed on the lower support plate 3 is provided below the sliding vertical plate 8 .

[0070] In this embodiment, a limiting groove 95 is opened on one side of the third slider 92 and the slide groove 81, and the limiting groove 95 does not penetrate the third slider 92 and the slide groove 81, so that when the limiting column 94 enters the bottom of the limiting groove 95 on one side of the third slider 92 and the slide groove 81, the third slider 92 and the slide groove 81 can be blocked to prevent the third slider 92 and the slide groove 81 from sliding out of the third T-shaped slide rail 91 and the fourth T-shaped slide rail 93, and the position of the limiting column 94 on the third T-shaped slide rail 91 and the fourth T-shaped slide rail 93 is not limited and can be set according to actual needs.

[0071] Example 4

Based on Example 1, this embodiment provides a further scheme of an auxiliary counterweight assembly 7, the purpose of which is to assist the drone in balancing the hovering state of the drone when the lateral telescopic assembly 5 is telescoped. The specific structure of the auxiliary counterweight assembly 7 in this embodiment will be described in detail below.

[0073] The auxiliary counterweight assembly 7 includes two fifth T-shaped slide rails 71 and two fifth sliding blocks 72 , and a counterweight block 73 mounted on the fifth sliding blocks 72 .

[0074] Among them, two fifth T-shaped slide rails 71 are installed in parallel on the lower surface of the lower support plate 3, and two fifth sliders 72 are respectively slidably set on the two fifth T-shaped slide rails 71. At the same time, the sliding direction of the fifth slider on the fifth T-shaped slide rail 71 is parallel to and opposite to the contraction and extension direction of the shear frame 53. Therefore, the distance that the counterweight block 73 moves on the fifth T-shaped slide rail 71 driven by the fifth slider is combined with the position of the load storage box 6 driven by the auxiliary lateral telescopic component 5 to level the hovering state of the drone to prevent the hovering state of the drone from being unbalanced.

The lead screw 76 is installed in the middle part of the two fifth T-shaped slide rails 71 through two bearing seats 75. The output shaft of the second motor 74 can be directly connected to the end of the lead screw 76, or connected to the end of the lead screw 76 through a coupling. The second motor 74 is electrically connected to the drone body 11, thereby providing power support and control through the drone body 11, and then using the second motor 74 to drive the lead screw 76 to rotate, and the lead screw A lead screw nut 77 is provided on 76 through a threaded sleeve, and the lead screw nut 77 is connected to the lead screw 76 through a thread, so that when the lead screw 76 rotates, the lead screw nut 77 is driven to move on the lead screw 76, and the lead screw nut 77 is connected to the two fifth sliders 72 through connecting rods respectively, so that when the lead screw nut 77 moves on the lead screw 76, the two fifth sliders 72 are driven to move on the fifth T-shaped slide rail 71, and then the counterweight block 73 is driven to move, and the auxiliary lateral telescopic component 5 drives the load storage box 6 to move to the position, so as to level the hovering state of the drone and prevent the hovering state of the drone from being unbalanced.

[0076] The working principle of an aerial load-carrying and object-delivering device based on a drone in this scheme is as follows:

[0077] In practical application, the present invention refers to Figure 1-Figure 11 First, the device puts the items to be transported into the load storage box 6, and uses the drone body 1 to deliver the items to be transported to the air destination (such as the customer's window at home) and then hovers.

[0078] Then, the drone body 1 drives the electric push rod 514 to push the first connecting rod 513 to move downward, driving the two first sliders 512 to move downward on the two first T-shaped slide rails 511, thereby driving the shear frame 53 to extend, realizing the lateral displacement of the load storage box 6, and extending or retracting the load storage box 6 out of the hovering range of the drone.

[0079] At the same time, the drone body 1 drives the lead screw 76 to rotate through the second motor 74, so that the lead screw nut 77 moves on the lead screw 76, driving the counterweight blocks 73 on the two fifth sliders 72 to move on the fifth T-shaped slide rail 71, and cooperating with the auxiliary lateral telescopic component 5 to drive the load storage box 6 to move its position, so as to level the hovering state of the drone and prevent the hovering state of the drone from being unbalanced.

[0080] Finally, the customer opens the load storage box 6 with a preset password and takes out the transported items inside. After the customer takes out the transported items, the drone body 1 simultaneously controls the electric push rod 514 and the motor 74 to restore the load storage box 6 and the counterweight block 73 to their original positions and then return to the departure point.

[0081] Although the specific implementation of the invention is described in detail in conjunction with the drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
