[0040] At present, a dropping device is arranged below an aircraft or other device to drop articles, such as can be used to air-drop supplies to areas where ground transportation is difficult to reach, but the dropping device currently available can only be used to air-drop general supplies, and the dropping device has a complex structure and a relatively high failure rate, and in some special fields, such as the military field or the criminal investigation field, the fire fighting field, it is necessary to use a UAV or other aircraft to perform a bomb-throwing task, the bomb in the throwing device cannot be shaken, the throwing device is quickly opened when the bomb is dropped, and finally the bomb falls to the designated place, so the bomb has a relatively high requirement for the dropping device.

[0041] However, in the prior art, in order to improve the reliability of the throwing device, most bomb clamping devices use high-power electrical appliances or hydraulic devices, but the use of high-power electrical appliances or hydraulic devices has a complex structure and a large weight, which is easy to cause the problem of mis-dropping of supplies.

[0046] The clamping assembly 20 includes a first clamping unit 210 and a second clamping unit 220, the first clamping unit 210 is arranged on the first end plate 120, and the second clamping unit 220 is arranged on the second end plate 130, so that the first clamping unit 210 and the second clamping unit 220 are distributed on the two ends of the bottom plate 110, wherein, as shown in Figure 1As shown, the first clamping unit 210 is connected to the first end plate 120, so that the clamping part of the first clamping unit 210 is exposed to the periphery of the first end plate 120, and the second clamping unit 220 is connected to the second end plate 130, so that the clamping part of the second clamping unit 220 is exposed to the periphery of the second end plate 130. The first clamping unit 210 and the second clamping unit 220 together clamp and release the thrown object, thereby achieving grabbing and throwing of the thrown object.

[0047] The driving assembly 30 includes a driving unit 310 and a fixing unit 320, both of which are arranged on the bottom plate 110, and the output shaft of the driving unit 310 is connected to the fixing unit 320.

[0060] Similarly, as shown in Figure 4 The second clamping unit 220 designed in the scheme includes a second clamping jaw 2210 and a second elastic member 2220; the second clamping jaw 2210 includes a third connecting part 22110 and a third arc-shaped clamping part 22120 connected with the third connecting part 22110, and a fourth connecting part 22130 and a fourth arc-shaped clamping part 22140 connected with the fourth connecting part 22130; the third connecting part 22110 has a third protrusion 22150, the fourth connecting part 22130 has a fourth protrusion 22160, the third protrusion 22150 and the fourth protrusion 22160 are opposite, a third connecting hole 22170 is formed on the third protrusion 22150, a fourth connecting hole 22180 is formed on the fourth protrusion 22160, a second bearing 22190 is arranged in the third connecting hole 22170 and the fourth connecting hole 22180, the third connecting part 22110 and the fourth connecting part 22130 are rotatably connected through the second bearing 22190, and the second elastic member 2220 is arranged between the third connecting part 22110 and the fourth connecting part 22130. The second clamping jaw 2210 is rotatably connected with the second end plate 130 through the third connecting part 22110 and the fourth connecting part 22130, and the two arc-shaped clamping parts of the second clamping jaw 2210 are used for clamping the thrown object.

[0061] Specifically, please continue to refer to Figure 1 and 4The first end plate 120 and the second end plate 130 are respectively provided with two clamping jaw connecting holes, the end portions of the first connecting portion 21110 and the second connecting portion 21130 and the third connecting portion 22110 and the fourth connecting portion 22130 are respectively provided with counterbore holes, and each counterbore hole is provided with a bearing. Thus, the first clamping jaw 2110 is rotatably fixed on the first end plate 120 by connecting the counterbore holes, the bearings and the clamping jaw connecting holes on the first end plate 120 of the first connecting portion 21110 and the second connecting portion 21130 through a screw rod. The second clamping jaw 2210 is rotatably fixed on the second end plate 130 by connecting the counterbore holes, the bearings and the clamping jaw connecting holes on the second end plate 130 of the third connecting portion 22110 and the fourth connecting portion 22130 through a screw rod.

[0062] The above designed throwing device is initially in a locked state, the transmission rod 3210 and the rudder arm 3120 are in a flat state, the both end heads of the sliding rod 3220 are extended and respectively inserted into the first connecting hole 21170 and the second connecting hole 21180 of the first clamping jaw 2110 through the first through hole 1210 on the first end plate 120 and inserted into the third connecting hole 22170 and the fourth connecting hole 22180 of the second clamping jaw 2210 through the second through hole 1310 on the second end plate 130, so as to fix the first clamping jaw 2110 and the second clamping jaw 2210.

[0063] When the throwing is needed, the rudder 3110 is rotated to drive the rudder arm 3120 to rotate, one end of the transmission rod 3210 is rotated with the rudder arm 3120, and the other end pulls the sliding rod 3220 to slide along the axis and retract. After the both ends of the sliding rod 3220 retract to the middle, they can no longer pass through the first connecting hole 21170 and the second connecting hole 21180 and the third connecting hole 22170 and the fourth connecting hole 22180. Under the action of the gravity of the thrown object, the first connecting portion 21110 and the second connecting portion 21130 of the first clamping jaw 2110 overcome the tension of the first elastic member 2120, so that the first elastic member 2120 is stretched, and the first connecting portion 21110 and the second connecting portion 21130 are rotated around the rotary connection of the top end and the first end plate 120, so as to open the first clamping jaw 2110 to release the thrown object. Similarly, the third connecting portion 22110 and the fourth connecting portion 22130 of the second clamping jaw 2210 overcome the tension of the second elastic member 2220, so that the second elastic member 2220 is stretched, and the third connecting portion 22110 and the fourth connecting portion 22130 are rotated around the rotary connection of the top end and the second end plate 130, so as to open the second clamping jaw 2210 to release the thrown object, thereby achieving the throwing of the thrown object.

[0064] In addition, the throwing device designed in the scheme is used for releasing the throwing object, and the first elastic member 2120 and the second elastic member 2220 are elastically recovered due to the gravity of the throwing object. Thus, the first elastic member 2120 drives the first connecting part 21110 and the second connecting part 21130 of the first clamping jaw 2110 to rotate and recover to the clamping state of the first clamping jaw 2110, and the second elastic member 2220 drives the third connecting part 22110 and the fourth connecting part 22130 to rotate and recover to the clamping state of the second clamping jaw 2210. In this case, the rudder 3110 is controlled to rotate, so that the sliding rod 3220 slides along the axis and extends, and then the first clamping jaw 2110 and the second clamping jaw 2210 are further fixed.

[0065] The first elastic member 2120 and the second elastic member 2220 described above can be a tension spring, and can also be other elastic members, such as a torsion spring and a spring sheet.

[0066] The throwing device designed above is used for linkage between the sliding rod and the first clamping unit and the second clamping unit. Since the extension and retraction of the two ends of the sliding rod are synchronous, the throwing and releasing of the first clamping unit and the second clamping unit are basically synchronous, so as to avoid the throwing object from being deviated due to the asynchronization of the two ends, thereby improving the throwing accuracy of the throwing object. In addition, the first clamping unit and the second clamping unit designed in the scheme can recover to the clamping state based on the elastic recovery of the first elastic member and the second elastic member and the sliding of the sliding rod after the throwing object is thrown, so as to ensure that the throwing device is in the closed state after the throwing is completed, thereby further improving the safety of the throwing device.

[0067] In the optional embodiment of the embodiment, please continue to refer to Figure 4 The fourth connecting part 22130 of the second clamping jaw 2210 is rotatably connected with the fourth arc-shaped clamping part 22140. In this case, the second clamping unit includes a plug 2230, the plug hole 2240 is arranged on the fourth connecting part 22130, and the plug 2230 is arranged in the plug hole 2240, so as to fix the rotation of the fourth connecting part 22130 and the fourth arc-shaped clamping part 22140.

[0068] The second clamping unit 220 of the above design, since the fourth connecting part 22130 is rotatably connected with the fourth arc-shaped clamping part 22140, in the case of installing the throwing object by using the second clamping unit 220, the plug 2230 can be removed, the fourth arc-shaped clamping part 22140 is rotated towards the direction away from the third arc-shaped clamping part 22120, so that the clamping range of the second clamping jaw 2210 is expanded, after the throwing object is placed in the clamping range of the second clamping jaw 2210, the third arc-shaped clamping part 22120 is rotated to reset, and the plug 2230 is inserted, so that the installation of the throwing object by the second clamping unit 220 is completed. It should be noted that the disassembly of the throwing object is achieved by inversely executing the above mode.

[0069] In the above embodiment, the fourth connecting part 22130 is rotatably connected with the fourth arc-shaped clamping part 22140, and the rotation of the fourth connecting part 22130 and the fourth arc-shaped clamping part 22140 is fixed by the cooperation of the plug 2230 and the plug hole 2240 on the fourth connecting part 22130, so that the designed second clamping unit 220 can expand the clamping range and improve the convenience of installing the throwing object. In addition, the disassembly of the throwing object can also be achieved by the above mode, so that the disassembly of the throwing object does not need to be driven by electricity, and the reliability and safety of the operation of the throwing device are further improved.

[0070] In the optional embodiment of the present embodiment, the first arc-shaped clamping part 21120, the second arc-shaped clamping part 21140, the third arc-shaped clamping part 22120 and the fourth arc-shaped clamping part 22140 can be provided with rubber pads, so that the first clamping unit 210 and the second clamping unit 220 better fit the throwing object, and the clamping firmness and stability of the clamping assembly 20 to the throwing object are further improved.

[0071] In the optional embodiment of the present embodiment, please continue to refer to Figure 3 The first end plate 120 can be provided with a first limiting part 1220, and the second end plate 130 can be provided with a second limiting part 1320. The first limiting part 1220 is arranged between the first connecting part 21110 and the second connecting part 21130 of the first clamping jaw 2110, and the second limiting part 1320 is arranged between the third connecting part 22110 and the fourth connecting part 22130 of the second clamping jaw 2210. In this way, the rotation amplitude of the first connecting part 21110 and the second connecting part 21130 is limited by the first limiting part 1220 of the first end plate 120, and the rotation amplitude of the third connecting part 22110 and the fourth connecting part 22130 is limited by the second limiting part 1320 of the second end plate 130, so as to avoid the risk of falling due to excessive rotation amplitude of the first clamping jaw 2110 and the second clamping jaw 2210, and further improve the stability and reliability of clamping.

[0072] In an optional implementation of this embodiment, the bracket assembly 10 designed in this scheme may also include a cover plate 160 (not shown in the figure), the cover plate 160 is arranged parallel to the base plate 110, and the cover plate 160 is connected to the first end plate 120, the second end plate 130, the first side plate 140 and the second side plate 150, thereby shielding the internal components and preventing the internal components from falling off.

[0073] Based on the above, please refer to Figure 5 The throwing device designed in this scheme can also include a first limiting seat 40 and a second limiting seat 50. The first limiting seat 40 is connected to the cover plate 160 and the first clamping unit 210, and is used to limit the axial movement of the first clamping unit 210; the second limiting seat 50 is connected to the cover plate 160 and the second clamping unit 220, and is used to limit the axial movement of the second clamping unit 220.

[0074] As a possible embodiment, the first limit seat 40 and the second limit seat 50 can be an L-shaped support rod, which has a U-shaped hole. The two screws can respectively pass through the first connecting part 21110 and the second connecting part 21130 of the first clamping unit 210 and connect with the U-shaped hole of the first limit seat 40, thereby limiting the axial movement of the first clamping unit 210. The principle of the second limit seat 50 is the same, and it will not be elaborated on.

[0075] In the above embodiment, this scheme limits the axial movement of the first clamping unit by the first limit seat, and limits the axial movement of the second clamping unit by the second limit seat, so that the first clamping unit and the second clamping unit do not shake in the axial direction, further improving the clamping firmness and stability of the clamping assembly.

[0076] The throwing device designed in this proposal allows loading and unloading of objects even during power outages, significantly improving operational safety. Its overall structure is simple and reliable, reducing the weight of the throwing device. The device is locked both before and after the launch, further enhancing safety. Furthermore, to further reduce the weight of the throwing device, the base, side panels, cover, and clamping components are all constructed from carbon fiber. This significantly reduces the weight of the throwing device while maintaining structural strength, thereby increasing the drone's flight range.

[0077] This application also provides a throwing drone, such as Figure 6 As shown, the throwing drone includes a drone 1 and the throwing device 2 described above. The throwing device 2 is arranged on the drone 1. In this way, a lightweight and simple throwing drone design can be realized through the cooperation between the drone and the throwing device, thereby achieving accurate material throwing.

[0078] The throwing unmanned plane of the design can load and unload the throwing object in the case of power failure, greatly improves the safety of operation, and has simple and reliable overall structure, reduces the weight of the throwing device, and the bomb-thrower is in the locked state before and after the bomb-throwing, further improving the safety. In addition, in order to further reduce the weight of the throwing device, the bottom plate, the side plate, the cover plate and the clamping assembly of the scheme can use carbon fiber plate material, which greatly reduces the weight of the throwing device under the premise of ensuring the structural strength, and further improves the endurance of the unmanned plane.
