Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1, fig. 1 is a schematic perspective view of a mounting and dismounting mechanism 100 according to an embodiment of the present invention. The loading and unloading mechanism 100 is used for loading and unloading the cargo compartment 200, and referring to fig. 4, a hanger 210 is provided on the cargo compartment 200, and the loading and unloading mechanism 100 can be hooked on the hanger 210. The hanger 210 extends vertically upward to facilitate automatic hooking of the hanger 210 by the handling mechanism 100.

As shown in fig. 1, the attachment/detachment mechanism 100 includes a base 110, a hook 120, and a driving member 130. The base 110 may be mounted on a drone, a cart, a crane, or the like. The unmanned aerial vehicle, the carrying trolley, and the crane are common carrying devices in the field of logistics, but the loading and unloading mechanism 100 may be mounted on other carrying devices.

The specific structure of the attachment/detachment mechanism 100 will be described below.

The hook 120 of the attachment/detachment mechanism 100 includes an attachment portion 121, a driving portion 122, and a hanging portion 123. The mounting portion 121 is rotatably coupled to the base 110 so that the entire hook 120 can be rotated with respect to the base 110, thereby implementing the loading and unloading mechanism 100 with the bin 200 or the bin 200. Wherein, when the loading and unloading mechanism 100 loads the cargo compartment 200, the hanging part 123 of the hook 120 hooks the hanging part 210 of the cargo compartment 200; when the loading/unloading mechanism 100 unloads the cargo compartment 200, the hanging portion 123 of the hook 120 is detached from the hanger 210. The driving member 130 connects the base 110 and the driving portion 122, and the hook 120 is driven to rotate relative to the base 110 by the driving member 130, so that the hanging member 210 of the cargo compartment 200 is separated from the hanging portion 123.

As shown in fig. 1, the hanging portion 123 has an inner hook surface 123A and an outer surface 123B connecting the inner hook surface 123A. Here, the positions of the inner hook surface 123A and the outer surface 123B are described in detail, and as shown in fig. 2, fig. 2 is a front view of the hook 120 in the attachment/detachment mechanism 100 shown in fig. 1, the outer surface 123B is located at the bottom of the hanging portion 123 shown in fig. 2, and the inner hook surface 123A is located on the left side of the hanging portion 123 shown in fig. 2.

Referring to fig. 1 and 2, the inner hook surface 123A includes a first surface 123A1 and a second surface 123A 2. The first surface 123a1 connects the outer surface 123B and the second surface 123a 2. The first surface 123a1 and the second surface 123a2 form a hooking groove 123A3 for hooking the hanger 210. When the hook groove 123A3 hooks the suspension member 210, the first surface 123a1 is inclined upward so that the suspension member 210 is positioned at the bottom of the hook groove 123A3 and the suspension member 210 is attached to the first surface 123a1 and the second surface 123a 2. The first surface 123a1 is inclined upwardly-specifically, as shown in fig. 2, the end of the first surface 123a1 that is connected to the outer surface 123B (i.e., at a in fig. 2) is at a higher level than the end of the first surface 123a1 that is connected to the second surface 123a2 (i.e., at B in fig. 2), so that the cargo compartment 200 will have a tendency to rotate about the first direction (in conjunction with fig. 3) relative to the base 110 under the force of gravity to hook up the hanger 210. That is, when the hook groove 123A3 hooks the hanger 210, the first surface 123a1 is disposed to be inclined upward from the bottom end of the hook groove 123 A3. Here, taking the view shown in fig. 1 and 2 as an example, the hook 120 rotates around the first direction relative to the base 110 and around the clockwise direction.

Fig. 3 is a schematic view illustrating a force analysis of the hook groove 123A3 by the hanger 210 when the hook groove 123A3 hooks the hanger 210, as shown in fig. 3. By designing the gravity center position of the hook 120, for example, taking the hook 120 in fig. 2 as an example, the gravity center position of the hook 120 is directly above and to the left of the hanging portion 123, when the hanger 210 pushes the hook 120 open, the hook 120 will rotate the rotating shaft 400 in the second direction (counterclockwise direction in the view angle of fig. 2) to move the hanging portion 123 to the right; when the hanger 210 moves above the first surface 123a1, the hook 120 rotates in the first direction (clockwise in the view of fig. 2) about the rotation shaft 400 by gravity, and thus the hanging portion 123 moves leftward to allow the hanger 210 to enter the hook groove 123 A3.

Specifically, in fig. 3, the force components of the weight G of cargo compartment 200 are F1 and F12, and the force component F1 acts on first surface 123a 1. When the hook groove 123A3 hooks the hanging member 210, the hanging member 210 generates a downward pressure F1 on the first surface 123a1 perpendicular to the first surface 123a1 under the gravity G of the cargo compartment 200. Referring to fig. 2, the rotation axis 400 is located at the left side of the hanging part 123, the center of gravity of the hook 120 is located at the right side of the rotation axis 400, and the hook 120 always rotates around the first direction relative to the base 110 to hook the hanging part 210 under the action of the gravity G of the cargo compartment 200, so that the cargo compartment 200 is not separated from the hook 120 even if the cargo compartment 200 shakes. Further, the component force F12 of the gravity G of the cargo compartment 200 moves the hanger 210 toward the lower right in fig. 3, that is, the hanger 210 moves toward the bottom of the hook groove 123A3, so that the hanger 210 does not come off the hook groove 123 A3. The above-described attaching and detaching mechanism 100 has an advantage of firmly hooking the cargo compartment 200 so that the hanger 210 is not easily detached from the hook groove 123a 3. When ordinary unmanned aerial vehicle carried warehouse 200, make the warehouse produce in the air easily and rock, make warehouse 200 break away from with unmanned aerial vehicle easily, and have the potential safety hazard. When the drone includes the above-described handling mechanism 100, the drone carries the cargo compartment 200, the hanger 210 of the cargo compartment 200 does not easily come off from the hook groove 123a3 of the handling mechanism 100.

When the loading and unloading mechanism 100 is installed on an unmanned aerial vehicle, a carrying trolley, a crane and other equipment, the automatic loading and unloading of the cargo compartment 200 can be realized.

For example, the base 110 of the attachment/detachment mechanism 100 may be mounted on the body 300 of the drone; the base 110 of the handling mechanism 100 may be mounted on a mobile arm of a carrying cart or crane, wherein the mobile arm may be vertically movable up and down.

When the body 300 of the unmanned aerial vehicle or the moving arm of the carrier or the moving arm of the crane descends vertically, the loading and unloading mechanism 100 descends therewith, and the automatic loading of the cargo compartment 200 can be completed at this time. The cargo compartment 200 may include two upwardly extending suspension members 210. referring to fig. 1 and 2, as the suspension members 210 abut the outer surface 123B of the hanging portion 123, the attachment mechanism 100 continues to descend and the suspension members 210 rise along the outer surface 123B of the hanging portion 123. At this time, under the abutting action of the hanger 210 against the outer surface 123B of the hanging portion 123, the hook 120 rotates around the base 110, i.e., rotates in the counterclockwise direction in the view of fig. 1 or 2, and the hanger 210 moves upward above the hanging portion 123. The loading and unloading mechanism 100 is then raised and the hanger 210 of the bin 200 fully enters the hook slot 123a3 of the hook 120.

When the automatic unloading of the cargo compartment 200 is required, the output shaft of the driving member 130 of the loading and unloading mechanism 100 rotates, and the driving portion 122 of the hook 120 is pulled by the first and second rotating arms 131 and 132, so that the mounting portion 121 of the hook 120 rotates about the base 110. At this time, the hanger 210 of the cargo compartment 200 is disengaged from the hook groove 123a 3. At this point, the automatic unloading of the cargo bin 200 is completed.

As shown in fig. 2, the outer surface 123B is a guide surface. During loading of the loading/unloading mechanism 100 in the cargo compartment 200, the hanger 210 of the cargo compartment 200 contacts the outer surface 123B as a guide surface. The hanger 210 moves vertically upward or the hook 120 moves vertically downward, and the relative movement of the hanger 210 and the outer surface 123B is specifically that the hanger 210 can slide along the outer surface 123B to push the hook 120 to rotate relative to the base 110 about the second direction, so that the hanger 210 can enter the hook groove 123a 3. Referring to fig. 3, the second direction is opposite to the first direction. That is, the loading and unloading mechanism 100 may not need the driving force of the driving member 130 during loading the cargo compartment 200, but may rely on the suspension member 210 to contact the outer surface 123B as a guide surface, thereby ejecting the hook 120. By designing the gravity center position of the hook 120, for example, taking the hook 120 in fig. 2 as an example, the gravity center position of the hook 120 is directly above and to the left of the hanging portion 123, when the hanging member 210 pushes the hook 120 open, the hook 120 will rotate around the second direction (counterclockwise direction in the view angle of fig. 2) to move the hanging portion 123 to the right; when the hanger 210 moves above the first surface 123a1, the hook 120 rotates about the first direction (clockwise in the view of fig. 2) by gravity, and thus the hanging portion 123 moves leftward to allow the hanger 210 to enter the hook groove 123 A3.

As shown in fig. 1, the driving member 130 may be a motor, and the output end of the driving member 130 is an output shaft of the motor. The output end of the driving member 130 is connected with a first rotating arm 131, the first rotating arm 131 is rotatably connected with a second rotating arm 132, and the second rotating arm 132 is rotatably connected with the driving portion 122 of the hook 120. When the loading and unloading mechanism 100 needs to unload the cargo compartment 200, the output shaft of the driving member 130 rotates to drive the first rotating arm 131 to rotate; the first rotating arm 131 drives the second rotating arm 132 to move, the second rotating arm 132 pulls the driving part 122 shown in fig. 1 to move leftward, and the mounting part 121 of the hook 120 rotates in the second direction around the rotating shaft 400 of the base 110, so that the hanging member 210 of the cargo compartment 200 is disengaged from the hook groove 123a3 of the hook 120, thereby completing the unloading process of the cargo compartment 200.

As shown in fig. 1, the attachment/detachment mechanism 100 further includes an elastic member 140. The elastic member 140 may be a torsion spring or a straight spring. The elastic member 140 has both ends connected to the hook 120 and the base 110, respectively, to cause the hook 120 to have a tendency to rotate about the first direction. Explaining the first direction, the driving portion 122 of the hook 120 is away from the driving member 130 when the hook 120 rotates in the first direction. Therefore, the elastic member 140 may press the hook 120, thereby preventing the hook 120 from freely shaking. Especially when the cargo compartment 200 is light, the elastic member 140 may restrict the hook 120 from shaking, and also further serve to stabilize the cargo compartment 200.

As shown in fig. 1, there are two hooks 120. The two hooks 120 are spaced apart. The two hooks 120 can be used to hook the same hanger 210 and can also limit the shaking of the cargo compartment 200 during the transportation of the cargo compartment 200.

As shown in fig. 4, fig. 4 is a schematic structural diagram of the unmanned aerial vehicle hoisting cargo compartment 200 in an embodiment of the present invention. The drone includes a body 300 and a loading and unloading mechanism 100. The body 300 has a first end 301 and a second end 302, the left end in fig. 4 is the first end 301, and the right end is the second end 302. At least two attachment/detachment mechanisms 100 are provided, and are provided at the first end 301 and the second end 302, respectively. The attachment/detachment mechanism 100 may be the attachment/detachment mechanism 100 in the above-described embodiment.

As shown in fig. 5, fig. 5 is a partial structural schematic view of the structure shown in fig. 4. The base 110 of the attachment/detachment mechanism 100 is attached to the body 300 of the unmanned aerial vehicle. Referring to fig. 1, the hook 120 of the attachment/detachment mechanism 100 attached to the first end 301 of the body 300 is located at the left end of the body 300, and the hook 120 of the attachment/detachment mechanism 100 attached to the second end 302 of the body 300 is located at the right end of the body 300. Referring to fig. 2, the hook grooves 123a3 of the hooks 120 are all facing the body 300. And the hook 120 can be supported on the body 300. Specifically, the portion where the first surface 123a1 and the outer surface 123B of the hook 120 meet (i.e., a portion in fig. 5) can be abutted against the body 300. Thus, when the hanger 210 is hung in the hook groove 123A3 (shown in fig. 1), the body 300 can restrict the hanger 210 from being detached from the hook groove 123 A3.

As shown in fig. 5, the outer surface 123B as the guide surface is a flat surface.

As shown in fig. 5, when the hanging member 210 is located in the hook groove 123a3 (shown in fig. 1), the surface of the body 300 abutting against the hanging portion 123a of the hook 120 is a third surface 310, and the third surface 310 is also a plane. The process of the hanger 210 entering the hook groove 123a3 (shown in fig. 1) from the outside of the hanging part 123 is as follows:

the hanging member 210 first ascends along the third surface 310 of the body 300 from the lower direction, and then the hanging member 210 abuts against the outer surface 123B of the hanging portion 123. As the outer surface 123B is inclined upward, the hanging member 210 slides upward along the outer surface 123B as the hanging member 210 continues to move upward, and the hanging member 210 can push the hanging portion 123 away from the body 300, i.e., the position a of the hanging portion 123 in fig. 5 is disengaged from the third surface 310 of the body 300, so that the hanging member 210 can move upward and enter the hook groove 123a3 (shown in fig. 1). When the hanging member 210 is hung on the attachment/detachment mechanism 100, the hanging member 210 tends to move toward the body 300 by the gravity of the cargo compartment 200. Therefore, when the attachment/detachment mechanism 100 is suspended from the hanger 210, the portion a of the suspension portion 123 can abut against the third surface 310 of the body 300. Therefore, when the attachment/detachment mechanism 100 hangs the hanger 210, the hanger 210 cannot be detached from the hook groove 123a 3.

Foretell unmanned aerial vehicle can realize the auto-control handling to warehouse 200.

As shown in fig. 5, the automatic loading of the cargo compartment 200 by the drone is performed as follows. The cargo compartment 200 may be placed on a cargo platform for positioning. Wherein the cargo compartment 200 may comprise two upwardly projecting suspension members 210. The drone can be automatically positioned to a specific location of the cargo compartment 200 by a positioning device. When the drone flies right above the cargo hold 200, the two attachment/detachment mechanisms 100 of the drone are respectively located right above the two hangers 210 of the cargo hold 200. The drone then starts to descend so that the two suspension members 210 of the bin 200 are at the ends of the body 300, and the drone continues to descend with the suspension members 210 abutting against the outer surface 123B of the suspension portion 123 of the handling mechanism 100. It should be noted that, when the hanging member 210 is not in contact with the hanging portion 123, the position a of the hook 120 is abutted against the third surface 310 of the body 300 under the action of the self-weight of the hook 120. When the hanging member 210 abuts against the outer surface 123B of the hanging portion 123, the unmanned aerial vehicle continues to descend, and the hanging member 210 rises along the outer surface 123B of the hanging portion 123 and the third surface 310 of the body 300. At this time, under the abutting action of the hanging part 210 and the outer surface 123B, the hook 120 rotates around the base 110, and the rotation direction is specifically the rotation direction of the hook 120 around the base 110 in the counterclockwise direction in fig. 5, so that the position a of the hanging part 123 of the hook 120 is far away from the body 300 of the unmanned aerial vehicle, thereby forming a gap between the hanging part 123 and the body 300 of the unmanned aerial vehicle, through which the hanging part 210 of the cargo compartment 200 passes, that is, a gap between the position a of the hanging part 123 and the third surface 310 of the body 300. After the hanging member 210 passes through the gap upward, the hanging portion 123 of the hook 120 again abuts against the third surface 310 of the main body 300 of the drone under the self-weight of the hook 120. The drone then starts to rise and the suspension 210 of the cargo compartment 200 enters completely into the hook slot 123a3 of the hook 120.

The steps for unmanned aerial vehicle to automatically unload cargo bay 200 are as follows. When the drone carries the cargo bay 200 directly above the destination location, the drone begins to descend. During the descending process of the unmanned aerial vehicle, the output shaft of the driving element 130 rotates, and the driving part 122 of the hook 120 is pulled through the first rotating arm 131 and the second rotating arm 132, so that the mounting part 121 of the hook 120 rotates around the base 110, and the hanging part 123 is far away from the third surface 310 of the machine body 300, i.e. a gap is formed between the position a of the hanging part 123 and the third surface 310 of the machine body 300. At this time, the hanger 210 of the bin 200 is disengaged downward from the gap, and the bin 200 is dropped to the destination position. To this end, the unmanned aerial vehicle has completed automatically unloading the cargo bay 200.
