[0020] like Figure 1-Figure 3 As shown, a drone delivery device according to an embodiment of the present invention includes: a box 1, a hook 2 and a controller 3.

[0021] The box body 1 is surrounded by a plurality of panels 10 to form a storage space for storing the drone to be launched.

[0022] In one embodiment, the plurality of panels 10 constituting the box body 1 include a top panel 100 and a plurality of side panels 102. Preferably, there are four side panels 102, and the four side panels 102 and the top panel 100 together form the box body 1 of a cubic structure.

[0023] Of course, the number of the side panels 102 may also be three, five, six, etc., and the present invention is not limited to the specific number of the side panels 102 .

[0024] In this embodiment, by not providing a bottom plate, on the one hand, the weight of the throwing device can be effectively reduced, and on the other hand, when throwing the drone, interference of the bottom plate to the drone can be avoided.

[0025] In one embodiment, the material of the plurality of panels 10 constituting the box body 1 is glass fiber, so as to reduce the weight of the box body 1 while ensuring the structural strength of the box body 1 .

[0026] In one embodiment, if Figure 1-Figure 3 As shown, the multiple panels 10 constituting the box body 1 are arranged as a hollow structure, so as to reduce the wind resistance of the box body 1 while reducing the weight of the box body 1, thereby avoiding the situation in which the throwing position cannot be controlled due to excessive wind resistance during the throwing process of the drone.

[0027] like Figure 1-Figure 3 As shown, a plurality of side panels 102 are respectively connected to the top panel 100 through hinges 12, so that one end of the side panel 102 can rotate around the top panel 100, so as to enable the side panel 102 to switch between an expanded state and a locked state.

[0028] Optionally, the hinge 12 is a hinge. Of course, the hinge 12 can also be made of other parts, as long as it can realize the hinge connection between the side plate 102 and the top plate 100, and the present invention is not limited to specific parts.

[0029] In one embodiment, a first elastic member (not shown in the figure) is provided on the hinge 12 connecting the side panel 102 and the top panel 100, and the first elastic member is respectively pressed between the top panel 100 and the side panel 102, so that the side panel 102 can automatically expand under the elastic force of the first elastic member.

[0030] Specifically, the first elastic member is a spring, which is passed through the hinge shaft of the hinge member 12 , and two ends of the spring abut against the top plate 100 and the side plate 102 respectively.

[0031] like Figure 1-Figure 3 As shown, the hook 2 passes through one of the multiple panels 10, and a part of the hook 2 is in the accommodation space of the box 1, and the other part is outside the box 1. The part of the hook 2 in the accommodation space of the box 1 is used to fix the drone to be thrown in the accommodation space, and the part of the hook 2 outside the box 1 is used to connect the transporter to achieve the connection between the throwing device and the transporter. Preferably, the hook 2 passes through the top plate 100 of the multiple panels 10.

[0032] like Figure 2 and Figure 3 As shown, the controller 3 is disposed on one of the multiple panels 10, and the controller 3 is used to control some of the multiple panels 10 to be in an unfolded state (such as Figure 3 to release the drone.

[0033] In one embodiment, the controller 3 is used to control the multiple side panels 102 to be in an unfolded state. A connecting structure 14 is provided between each two adjacent side panels 102 of the multiple side panels 102. When the connecting structure 14 is in a first state, the two adjacent side panels 102 are fixedly connected, and the multiple side panels 102 are in a locked state and are combined with the top panel 100 to form the box body 1; when the connecting structure 14 is in a second state, the connection between the adjacent side panels 102 is disconnected, and under the elastic force of the first elastic member, the multiple first side panels 102 are in an unfolded state (such as Figure 3 As shown in the figure), the drone is thrown.

[0034] The controller 3 is electrically connected to the plurality of connection structures 14 , and controls the connection structures 14 to switch between the first state and the second state through the controller 3 .

[0035] In one embodiment, if Figure 1As shown, the connection structure 14 includes a first connection member 140 and a second connection member 142 , wherein the first connection member 140 and the second connection member 142 are respectively arranged on two adjacent side panels 102 , and the controller 3 is electrically connected to the first connection member 140 and / or the second connection member 142 .

[0036] When the controller 3 controls the connection structure 14 to be in the first state, the first connection member 140 and the second connection member 142 are connected to each other, and at this time, each adjacent side panels 102 are in a locked state. When the controller 3 controls the connection structure 14 to be in the second state, the first connection member 140 and the second connection member 142 are disconnected, and at this time, the plurality of side panels 102 are in an unfolded state.

[0037] Optionally, the first connecting member 140 is a U-shaped opening structure 1400 formed on the side plate 102, and the second connecting member 142 includes a protrusion 1420 rotatably connected to the side plate 102 and a driving portion 1422, wherein the driving portion 1422 is connected to the protrusion 1420 so as to drive the protrusion 1420 to rotate through the driving portion 1422. The controller 3 is connected to the driving portion 1422 of the second connecting member 142 for controlling the action of the driving portion 1422.

[0038] When the controller 3 controls the driving unit 1422 to operate, the driving unit 1422 drives the protrusion 1420 to rotate, so that the protrusion 1420 extends into the opening of the U-shaped opening structure 1400, the connection structure 14 is in a connected state (i.e., a first state), and the adjacent side panels 102 are in a locked state. When the controller 3 controls the driving unit 1422 to operate, the driving unit 1422 drives the protrusion 1420 to rotate, so that the protrusion 1420 is separated from the opening of the U-shaped opening structure 1400, the connection mechanism is in a disconnected state (i.e., a second state), and the adjacent side panels 102 are in an unfolded state.

[0039] In one embodiment, if Figure 1 and Figure 3 As shown, among the multiple U-shaped opening structures 1400, the openings of some of the U-shaped opening structures 1400 are oriented toward the top plate 100, and the openings of other U-shaped opening structures 1400 are oriented away from the top plate 100. By limiting the opening directions of the multiple U-shaped opening structures 1400, the connection structure 14 can be effectively prevented from being disconnected by mistake.

[0040] Optionally, the driving part 1422 of the second connecting member 142 is a steering gear, and the controller 3 is a steering gear controller 3. Of course, the driving part 1422 can also be other components, such as a motor, etc. The present invention is not limited to specific components, as long as it can drive the protrusion 1420 to rotate.

[0041] According to another embodiment of the present invention, a UAV dropping system is provided, and the UAV dropping system includes: a transport aircraft, a UAV to be dropped, and the UAV dropping device described in any one of the above embodiments.

[0042] The transporter is used to transport the drone and the throwing device to a designated location, and the drone is placed in the accommodation space of the box 1 of the throwing device and fixed in the accommodation space by the hook 2 of the throwing device. When the transporter arrives at the designated location, the controller 3 of the throwing device controls the multiple side panels 102 to be in an unfolded state, and the unhooking device provided on the drone unhooks the drone from the throwing device, thereby realizing the throwing of the drone.

[0043] In one embodiment, the wings of the UAV are configured as a foldable structure. When the UAV is placed in the box 1 of the throwing device, the wings of the UAV are in a folded state. When the multiple side panels 102 of the throwing device are in an unfolded state, the wings of the UAV are transformed from a folded state to an unfolded state under the action of the second elastic member.

[0044] When the throwing device of the drone of the present invention is delivered to a designated location by a transport aircraft, the throwing of the drone can be achieved by controlling the unfolding of multiple side panels through a controller without requiring excessive operations, thereby effectively simplifying the throwing process of the drone. The throwing device has a simple structure and low production cost.
