Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1: As Figures 1-5 ,include:

[0028] The drone body 100 has a load slot 200 on the inner wall of its abdomen, and a load docking port 210 is fixedly installed on the inner wall of the bottom end of the load slot 200.

[0029] The load assembly includes a housing 300, elastic connecting buckles 310 on the left and right outer walls of the housing 300, and the bottom end of the housing 300 is inserted into the inner wall of the load slot 200.

[0030] The specific usage scenario of this embodiment is as follows: When it is necessary to carry a payload component, the operator holds the payload component with the housing 300 and aligns the bottom end of the housing 300 with the payload slot 200 on the inner wall of the abdomen of the UAV body 100. Since the buckles 310 elastically connected to the outer walls on the left and right sides of the housing 300 have a certain elastic deformation capability, during the insertion process, the buckles 310 will shrink inward due to the pressure of the inner wall of the payload slot 200. When the bottom end of the housing 300 is fully inserted into the payload slot 200, the buckles 310 return to their original shape, thus achieving the initial fixation of the payload component. At this time, the payload docking port 210 on the inner wall of the bottom end of the payload slot 200 establishes a connection with the corresponding electrical connection part inside the housing 300, completing the electrical connection between the payload component and the UAV body 100, so that the payload component can work under the control of the UAV.

[0031] Example 2: Figure 1 and Figure 2 Support rods 110 are fixedly installed at the four corners of the bottom of the UAV body 100. Four sets of support rods 110 are symmetrically distributed. A bracket 120 is fixedly installed on the outer wall of the support rod 110. A leg 121 is fixedly installed on the inner wall of the bottom end of the bracket 120. An anti-slip pad is fixedly installed on the outer wall of the bottom end of the leg 121. A servo motor 130 is fixedly installed on the outer wall of the end of the support rod 110. A propeller 131 is fixedly installed on the outer wall of the output shaft of the servo motor 130.

[0032] The specific application scenario of this embodiment is as follows: The support rods 110 fixedly installed at the four corners of the bottom of the drone body 100 serve to support the entire drone. When the drone lands, the outriggers 121 contact the ground through the anti-slip pads to increase friction and ensure the stability of the drone on the ground. The servo motors 130 are fixedly installed on the outer wall of the end of the support rods 110. When the drone needs to fly, the servo motors 130 are powered on and run. Their output shaft drives the propellers 131 to rotate at high speed. According to the forward and reverse rotation control of the motor, the propellers 131 generate lift in different directions, thereby realizing the drone's flight attitudes such as ascent, descent, hovering, and movement in the air. During flight, the four symmetrically distributed support rods 110, servo motors 130, and propellers 131 work together to ensure the stability and balance of the drone's flight.

[0033] Example 3: Figures 3-5The load slot 200 has first screw holes 240 on its front and rear outer sides. A first magnetic plate 230 is fixedly installed on the bottom inner wall of the load slot 200. A second magnetic plate 370 is fixedly installed on the top outer wall of the housing 300. The second magnetic plate 370 and the first magnetic plate 230 are magnetically connected. A docking terminal 360 is fixedly installed on the top outer wall of the load slot 200. The docking terminal 360 is plugged into the load docking port 210 for power supply. The load slot 200 has screw holes 240 on its left and right inner walls. The outer wall of the housing 300 has a locking groove 220 and a buckle 310. The buckle 311 and the inner wall of the locking groove 220 are engaged and connected. The outer walls of both sides of the housing 300 are fixedly connected to the reinforcing plates 320. The inner wall of the reinforcing plates 320 has a second screw hole. The second screw hole and the first screw hole 240 are distributed in a one-to-one correspondence. The second screw hole and the first screw hole 240 are fixedly connected by bolts. The outer wall of the housing 300 is fixedly installed with a camera 330. The fill light 340 is fixedly installed above the camera 330.

[0034] The specific application scenario of this embodiment is as follows: When installing the payload assembly, the housing 300 is first aligned with the payload slot 200 and inserted. During this process, the first magnetic suction plate 230 on the bottom inner wall of the payload slot 200 and the second magnetic suction plate 370 on the top outer wall of the housing 300 attract each other, generating a certain pre-tightening force to assist in the positioning and installation of the payload assembly. At the same time, the locking blocks 311 on the buckle 310 are aligned with and engaged with the locking grooves 220 on the left and right inner walls of the payload slot 200, further enhancing the firmness of the connection between the payload assembly and the UAV body 100. After the housing 300 is installed in place, the payload slot 200... The docking terminal 360 on the top outer wall is accurately inserted into the load docking port 210 to provide power and ensure that the equipment in the load assembly (such as the camera 330, the fill light 340, etc.) can work normally. The second screw hole on the inner wall of the reinforcing plate 320 corresponds to the first screw hole 240 on the front and rear sides of the load slot 200. The connection is further strengthened by bolts, which improves the connection between the load assembly and the UAV body 100 and enhances the stability of the overall structure. During operation, the camera 330 is used to capture images, and the fill light 340 provides illumination in low light conditions to meet the shooting needs in different environments.

[0035] The working principle of this utility model is as follows: When used by those skilled in the art, the support rods 110 and outriggers 121 at the four corners of the bottom of the UAV body 100 provide support during landing. During flight, the servo motor 130 drives the propeller blades 131 to rotate and generate lift to achieve various flight attitudes. When installing the payload assembly, the operator aligns the bottom of the housing 300 with the payload slot 200 on the belly of the UAV and inserts it. During this process, the buckle 310 is compressed and contracted, and the first magnetic suction plate 230 and the second magnetic suction plate 370 attract each other to assist in positioning. After insertion, the locking block 311 engages with the locking groove 220, and the docking terminal 360 is plugged into the payload docking port 210 to provide power. The reinforcing plate 320 is further reinforced and connected to the payload slot 200 by bolts. After installation, the equipment inside the payload assembly, such as the camera 330 and the supplementary light 340, obtain power and control signals through electrical connection under the control of the UAV to meet the working needs of different environments.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
