[0034] In addition, the centering and positioning assembly 2 further includes: a first centering piece 25 and a plurality of second centering pieces 26, the first centering piece 25 and the plurality of second centering pieces 26 respectively correspond to the plurality of slide slots 211 one by one, and the first centering piece 25 and the second centering piece 26 are respectively movably arranged in the corresponding slide slots 211 to push the tripod 12 to move. In other words, the total number of the first centering piece 25 and the second centering piece 26 is the same as the total number of the plurality of slide slots 211, and the first centering piece 25 and the plurality of second centering pieces 26 can slide in the corresponding slide slots 211, so that the tripod 12 of the drone assembly 1 that has landed on the top plate 21 can be pushed toward the center position of the top plate 21 by the first centering piece 25 and the plurality of second centering pieces 26, that is, the tripod 12 is pushed onto the turntable 24, so that the centering of the drone assembly 1 can be achieved.

[0035] As an optional embodiment, the number of the second centering members 26 is at least two, and the first centering member 25 and the plurality of second centering members 26 are evenly distributed along the circumference of the turntable 24.

[0036] The centering and positioning component 2 also includes: multiple driving components 28, which correspond to the first centering component 25 and the second centering component 26 one by one, respectively, to drive the first centering component 25 and the second centering component 26 to move, and the driving component 28 includes: a first mounting seat 281 and a second mounting seat 282, the first mounting seat 281 and the second mounting seat 282 are both fixedly connected to the side of the top plate 21 facing the ground, that is, the side away from the drone component 1, a screw rod 283 is arranged between the first mounting seat 281 and the second mounting seat 282, wherein the screw rod 283 is arranged close to the corresponding slide groove 211, and the axial direction of the screw rod 283 is the same as the length direction of the corresponding slide groove 211, one end of the screw rod 283 passes through the first mounting seat 281 and is fixedly connected to the second driving component 284, and a nut seat 285 is arranged on the screw rod 283, and one end of the nut seat 285 is connected to the corresponding first centering component 25 or the second centering component 26 through the corresponding slide groove 211.

[0037] For example, the second driving member 284 cooperating with the first centering member 25 is started, and the second driving member 284 drives the corresponding screw rod 283 to rotate, and the rotation of the screw rod 283 drives the first centering member 25 to move along the length direction of the corresponding slide groove 211 through the nut seat 285, thereby pushing and releasing the tripod 12. In specific use, multiple driving components 28 can be started at the same time, so that the first centering member 25 and multiple second centering members 26 can push the tripod 12 at the same time, so that the movement of the tripod 12 can be more stable, and the stability of the movement of the drone component 1 is improved.

[0038] As an optional embodiment, an elastic limiting plate 27 is provided on both the first centering member 25 and the second centering member 26 to limit the side wall of the tripod 12 away from the top plate 21. The elastic limiting plate 27 is made of an elastic material, and the elastic limiting plate 27 mainly plays a limiting role. When the first centering member 25 and the second centering member 26 are driven by the corresponding nut seat 285 to contact the outer wall of the tripod 12, the elastic limiting plate 27 is located above the tripod 12 to limit the upper part of the tripod 12, reduce the movement of the tripod 12 in the vertical direction, and improve the stability of the tripod 12 when moving.

[0039] The above can realize the centering operation of the drone component 1. The following mainly introduces the positioning of the drone component 1 to facilitate the subsequent charging and take-off operations of the drone component 1.

[0040] A matching groove 251 is provided on the first centering piece 25, and the matching groove 251 is located on the side of the first centering piece 25 facing the tripod 12. The drone assembly 1 also includes an elastic piece 13 and a matching rod 14. An installation groove 121 is provided on the outer wall of the tripod 12. One end of the elastic piece 13 is connected to the bottom of the installation groove 121, and the other end of the elastic piece 13 is connected to the matching rod 14. The matching rod 14 matches with the matching groove 251 to position the drone assembly 1.

[0041] Specifically, the elastic member 13 can be a spring. In the initial state of the spring, part of the mating rod 14 is located in the mounting groove 121, and the remaining part is located outside the mounting groove 121. The part of the mating rod 14 located outside is an arc-shaped protruding outward. When the first centering member 25 contacts the tripod 12, the mating rod 14 is just engaged with the mating groove 251. In this way, while completing the centering operation of the drone component 1, the positioning of the drone component 1 is also completed, and there is no need to rotate the turntable 24.

[0042] It should be noted that a transmission plate 122 is provided on the inner wall of the tripod 12, a through hole 241 is provided on the turntable 24, a mounting frame 242 is provided on the side wall of the turntable 24 away from the tripod 12, a first driving member 243 is provided on the mounting frame 242, a driving end of the first driving member 243 is fixedly connected to a transmission rod 244, and the transmission rod 244 selectively cooperates with the transmission plate 122 through the through hole 241. The centering positioning assembly 2 also includes: a connecting frame 29 and a third driving member 201, the connecting frame 29 is provided on the top plate 21, the third driving member 201 is provided on the connecting frame 29, and the driving end of the third driving member 201 is fixedly connected to a rotating shaft 202, and the end of the rotating shaft 202 away from the third driving member 201 is fixedly connected to the turntable 24

[0043] Specifically, when the first centering member 25 contacts the tripod 12 and the mating rod 14 does not fit exactly with the mating groove 251, when the drone assembly 1 completes the centering operation and moves to the turntable 24, the first driving member 243 is started, and the first driving member 243 moves the transmission rod 244 from the through hole 241 to the top of the turntable 24, and then the third driving member 201 is started. The third driving member 201 drives the turntable 24 to rotate through the rotating shaft 202, and the rotation of the turntable 24 will drive the transmission rod 244 to rotate around the center of the turntable 24. During the rotation of the transmission rod 244, the transmission rod 244 will contact the transmission plate 122, thereby driving the tripod 12 to rotate together. During the rotation of the tripod 12, the matching rod 14 will rotate with the tripod 12. When the matching rod 14 encounters the first centering piece 25 and the second centering piece 26, the matching rod 14 will shrink into the installation groove 121 under the action of pressure until the matching rod 14 is stuck in the matching groove 251 under the action of the spring, and the third driving member 201 stops working, completing the positioning of the drone assembly 1.

[0044] As an optional embodiment, a pressure sensor is provided inside the matching groove 251 to sense the pressure from the matching rod 14, and a controller is provided on the top plate 21, and the controller can be electrically connected to the first driving member 243, the second driving member 284, the third driving member 201 and the pressure sensor at the same time, so as to control the start and stop of the first driving member 243, the second driving member 284 and the third driving member 201. And the controller can analyze and process the information collected by the pressure sensor, so as to control the start of the third driving member 201, so as to achieve the purpose of controlling the start and stop of the turntable 24. For example, when the pressure sensor senses the pressure of the matching rod 14, it can transmit a signal to the controller, so that the controller controls the third driving member 201 to stop rotating.

[0045] The first driving member 243 may be an electric cylinder, and the second driving member 284 and the third driving member 201 may be motors.

[0046] As an optional embodiment, the first centering member 25 and the second centering member 26 are both arc-shaped structures, and the central angle of the first centering member 25 and the second centering member 26 is a, 10°≤a≤20°. The design of the arc-shaped structure can make the first centering member 25 and the second centering member 26 more adaptable to the outer wall of the tripod 12, thereby increasing the contact area between the first centering member 25 and the second centering member 26 and the tripod 12, so that the movement of the tripod 12 can be more stable.

[0047] As an optional embodiment, both ends of the first centering member 25 and the second centering member 26 are arc-shaped structures protruding outward. The arc-shaped structure can play a better guiding role. When the matching rod 14 contacts the ends of the first centering member 25 and the second centering member 26 during the rotation process, the part of the matching rod 14 extending out of the installation slot 121 can be better retracted under the guidance of the arc-shaped structure, reducing the force on the matching rod 14 and making the matching rod 14 less susceptible to damage.

[0048] As an optional embodiment, one side wall of the transmission plate 122 facing the rotating disk 24 is an outwardly protruding arc structure. Similarly, the arc structure mainly plays a guiding role, mainly to reduce the interference between the transmission rod 244 and the transmission plate 122. When the transmission rod 244 just contacts the bottom of the transmission plate 122 during the rising process, the transmission plate 122 will also rotate relative to the center of the rotating disk 24 during the upward movement under the guidance of the arc structure, so that the bottom of the transmission plate 122 can be separated from the top of the transmission rod 244, so that the transmission rod 244 can drive the transmission plate 122 to rotate.

[0049] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time.
