[0044] The blades 2 are multiple and fan-shaped, the multiple blades 2 are arranged around the tray 1, and each blade 2 is rotationally connected to the tray 1, and the rotation axis is referred to as an A rotation axis (the A rotation axis is at the edge of the tray), and each blade 2 is rotationally connected to the tray 1 through a corresponding first rotation shaft.

[0045] More specifically, one end of the first rotation shaft passes through a circle with the same radius, and the other end is located outside the circle, and the first rotation shaft is a tangent of the circle, and further, the circle is a virtual circle, and the end of the first rotation shaft divides the circle.

[0046] The support body 3 is arranged below the tray 1, and the vertical distance between the support body 3 and the tray 1 is adjustable and lockable, and the support body 3 comprises multiple adjusting rails 31, and the adjusting rails 31 are arranged around the support body 3; wherein the support body 3 comprises a circular plate body, and a plurality of connecting pieces 32 are arranged around the circular plate body, the connecting pieces 32 are scattered around the circular plate body, and the adjusting rails 31 are arranged below the connecting pieces 32.

[0047] Specifically, the adjusting track 31 is a strip-shaped annular channel, the guide rail 45 penetrates the adjusting track 31, and fasteners are arranged on both sides of the guide rail 45, so that the guide rail 45 does not deviate from the adjusting track 31 during movement.

[0048] In addition, the adjusting track 31 can also be a groove type track, and the guide rail 45 is embedded in the groove, and the guide rail 45 can move between both ends of the groove.

[0049] The adjusting members are multiple, each corresponding to the adjusting track 31, one end of each adjusting member is matched with the corresponding adjusting track 31, and the other end is rotationally connected with the corresponding blade 2, so as to adjust the stretching or folding of the blade 2.

[0050] Specifically, the adjusting member includes a first adjusting member 41, a second adjusting member 42, a third adjusting member 43, a fourth adjusting member 44, and a guide rail 45: the first adjusting member 41 is connected with the blade 2; the second adjusting member 42 is rotationally connected with one end of the first adjusting member 41 away from the blade 2, and the corresponding rotation axis is defined as B rotation axis (the B rotation axis is below the blade 2); the third adjusting member 43 is connected with the tray 1, the fourth adjusting member 44 includes a first element and a second element, the first element and the second element are connected and form an included angle, the position where the first element and the second element are connected is a connection, and the connection is rotationally connected with one end of the third adjusting member 43 away from the tray 1, and the corresponding rotation axis is defined as C rotation axis (the C rotation axis is below the tray 1); one end of the first element away from the connection is rotationally connected with one end of the second adjusting member 42 away from the first adjusting member 41, and the corresponding rotation axis is defined as D rotation axis (the D rotation axis is below the C rotation axis); the guide rail 45 is connected with one end of the fourth adjusting member 44 away from the second adjusting member 42 (that is, the guide rail 45 is arranged at one end of the first element away from the connection), the guide rail 45 is matched with the adjusting track 31, and the adjusting track 31 is perpendicular to the corresponding first rotation axis, that is, the design ensures that the running track of the guide rail is perpendicular to the first rotation axis.

[0051] More specifically, the cross section of the first adjusting member 41 can be triangular or rectangular, and the second adjusting member 42 is a rod-shaped body. The function of the first adjusting member is to ensure that the B rotation axis is below the blade 2. When the cross section of the first adjusting member 41 is triangular, the hypotenuse of the triangle is connected with the bottom surface of the blade 2, and the top position of the triangle is rotationally connected with the second adjusting member 42; if the second adjusting member 42 is a rectangular body, one face (referred to as A face) of the second adjusting member 42 is fixedly connected with the bottom surface of the blade, and the face opposite to the A face is rotationally connected with the second adjusting member 42, and the rotation axes of the first adjusting member 41 and the second adjusting member 42 are below the blade 2 and have a spacing from the bottom of the blade 2.

[0052] The fourth adjusting member 44 can be L-shaped or quasi-L-shaped, and the angle between the first and second members can be 90°, acute, or obtuse. As long as the fourth adjusting member 44 rotates on the third adjusting member 43, the blades 2 are in the extended state when the guide rail 45 is at one end of the adjustment track 31, and the blades 2 are in the retracted state when the guide rail 45 is at the other end of the adjustment track 31, the fourth adjusting member 44 can be L-shaped or quasi-L-shaped. The angle between the first and second members and the length of the second adjusting member 42 can be designed to match parameters.

[0053] A lifting mechanism 5 is provided on the base 0. This mechanism adjusts the distance between the tray 1 and the support 3 to enable the blades 2 to be deployed, partially retracted, and retracted. The lift adjusts the distance between the tray 1 and the support 3 and also locks the distance between them. The lifting mechanism 5 can be a screw lift or an electric lift.

[0054] When the lifting mechanism 5 is a screw lift, the lift includes a power component 51 and a screw. The power component 51 drives the screw to rotate. The support body 3 is provided with a threaded hole 33, through which the screw passes. The screw and the threaded hole 33 cooperate. The power component 51 can be a stepper motor. The delivery mechanism also includes a fixing member 6. One end of the fixing member 6 is connected to the base 0, and the other end is connected to the tray 1 to secure the tray 1 to the base 0.

[0055] When the lifting mechanism 5 is an electric lifting rod, the lifting mechanism 5 can lift the tray 1 or the support body 3. If the lifting mechanism 5 realizes the lifting and lowering of the support body 3, the delivery mechanism also includes a fixing member 6, the end of the fixing member 6 is connected to the base 0, and the other end is connected to the tray 1 to realize that the chassis is fixed on the base 0. The free end of the lifting rod is connected to the support body 3, and the support body 3 can move up and down under the drive of the lifting rod. If it is an electric lifting rod, a running space is reserved when the lifting rod descends to prevent the lifting rod from not being able to lift and lower normally. If necessary, a channel can be provided in the base 0; if the delivery mechanism adjusts the distance between the tray 1 and the support body 3 by lifting and lowering the tray 1, the delivery mechanism also includes a fixing member 6, the end of the fixing member 6 is connected to the base 0, and the other end is connected to the support body 3 to fix the support body 3 on the base 0. There is a through hole in the center of the support body 3, and the lifting rod moves freely in the through hole. The lifting rod is connected to the bottom of the tray 1, and the tray 1 can move up and down under the drive of the lifting rod. If necessary, a channel can be provided in the base 0 to reserve a running space when the lifting rod descends to prevent the lifting rod from not being able to lift and lower normally.

[0056] Specifically, the delivery mechanism has a first state and a second state. In the first state, the end of the adjusting member 4 (i.e., the guide rail 45) that is matched with the adjusting rail 31 is located at one end of the adjusting rail 31, and the blades 2 are unfolded to form a platform with the tray 1. In the second state, the end of the adjusting member 4 (i.e., the guide rail 45) that is matched with the adjusting rail 31 is located at the other end of the adjusting rail 31, and the blades 2 are folded to form a containing space with the tray 1. Between the first state and the second state, when the guide rail is located in the middle of the adjusting rail 31, the blades are half unfolded, and the blades and the tray can also form a containing space.

[0057] Specifically, when the blades 2 are completely unfolded, the blades form a ring-shaped plane, and the tray and each blade form a platform. Moreover, under the cooperation of the first rotating shaft corresponding to each blade, the blades 2 will not collide with each other during the folding process, and the blades are ensured to be smooth during the unfolding and folding processes.

[0058] The application also provides an embodiment in which the tray 1 is connected with a guide rod 9 below, the support body 3 is provided with a limiting hole 34, and the guide rod 9 penetrates through the limiting hole 34. During the up-and-down movement of the support body 3, the guide rod 9 also moves in the limiting hole 34 following the support body 3. The guide rod and the limiting hole prevent the support body from deviating during the operation process, improve the operation efficiency of the equipment, and also improve the service life of the equipment.

[0059] As shown in Figures 3-7 The delivery mechanism also includes a conveying mechanism 7, and the base 0 is connected with a conveying surface of the conveying mechanism 7.

[0060] Specifically, the conveying mechanism 7 can be an electric telescopic rod or an automatic bidirectional telescopic fork.

[0061] When the conveying structure is an electric telescopic rod, the base 0 is arranged on the top surface of the free end of the telescopic rod.

[0062] When the conveying mechanism 7 is a bidirectional telescopic fork, the base 0 is arranged on the conveying surface of the telescopic fork.

[0063] The bracket 8 supports the conveying mechanism 7, and the bracket 8 can be installed indoors. The bracket 8 has a rod body, which is connected with the bottom surface and the top of the indoor space or the wall surface. The rod body is used to firmly install the bracket 8 in the indoor space, so that the conveying mechanism 7 is stable during the conveying process.

[0064] The delivery mechanism includes a PLC control system, and the delivery mechanism is electrically controlled by the PLC control system. The PLC control system includes a communication module, which receives information of the unmanned aerial vehicle, transmits the received information to the PLC control system, and controls the operation of the delivery mechanism.

[0065] The working principle and use process of the present application are as follows:

[0066] The delivery mechanism can be used at the delivery end and the user end.

[0067] When the delivery end delivers, the blades of the delivery mechanism at the delivery end are unfolded, the goods are placed on the tray, and the signal is transmitted to the unmanned aerial vehicle, which takes away the goods. When the unmanned aerial vehicle reaches the user end, the unmanned aerial vehicle transmits the signal to the PLC control system of the delivery mechanism, the PLC control system receives the signal and controls the conveying mechanism 7 to transport the parts above the base of the delivery mechanism to the target position, and the following is the unfolding and folding process of the delivery mechanism:

[0068] The lifting mechanism 5 drives the support 3 to rise, and the support 3 moves towards the tray 1. In this movement process, the guide rail 45 moves in the adjusting rail 31, the fourth adjusting part 44 and the third adjusting part 43 rotate, the fourth adjusting part 44 pulls down the second adjusting part 42 away from one end of the adjusting rail 31, and as the second adjusting part 42 is pulled down, the second adjusting part 42 and the first adjusting part 41 rotate, so the blade 2 and the tray 1 also rotate, the blade 2 is unfolded and forms a platform with the tray 1; the unmanned aerial vehicle places the goods on the platform.

[0069] When the goods are placed on the platform, the lifting mechanism 5 drives the support 3 to descend, and the support 3 moves away from the tray 1. In this process, the guide rail 45 moves towards the other end of the adjusting rail 31 (that is, the running track of the guide rail is opposite to that when the blade is unfolded), the fourth adjusting part 44 and the third adjusting part 43 rotate, the fourth adjusting part 44 pushes up the second adjusting part 42 away from one end of the adjusting rail 31, and as the second adjusting part 42 is pushed up, the second adjusting part 42 and the first adjusting part 41 rotate, so the blade 2 and the tray 1 rotate, the blade 2 is folded and forms a containing space with the tray 1, at this time the goods are in the containing space formed by the blade 2 (if the unmanned aerial vehicle places the goods on the blade 2 and not on the tray 1, the goods are pushed onto the tray 1 during the folding process of the blade 2), and finally the conveying mechanism 7 transports the goods back to the initial position.

[0070] In addition, when the delivery mechanism transports goods, the blades can also be in a semi-folded state. When the blades are semi-folded, the containing space has a larger opening and a larger space than when they are fully folded.

[0071] In addition, the delivery mechanism can also be used for rescue. When an emergency occurs, personnel can stand on the tray, the blades are folded into a containing space, the conveying mechanism transports the personnel out of the dangerous area, the blades are unfolded after the personnel leave, and the process is continuously repeated.
