[0053] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0054] In the related art, with the increasing maturity of artificial intelligence technology and unmanned aerial vehicle technology, the active service riot grenade is combined with the aerial unmanned aerial vehicle, and the advantages of the aerial unmanned aerial vehicle such as rapid maneuvering and situation awareness are utilized, so that the maneuvering capability, projection range, projection accuracy and striking effectiveness of the active service riot grenade can be greatly improved. However, the existing automatic launching device has the problems of small amount of ammunition carried, low launching efficiency, and the like, which leads to the power of the ammunition carried by the unmanned aerial vehicle being weakened.

[0055] In order to solve the above technical problems, the embodiments of the present application are described below in combination with Figures 1 to 8 .

[0056] According to the embodiments of the present application, on one hand, as shown in Figures 1 to 3 , an automatic launching device is provided, which comprises a rack 1, a bomb carrying assembly 5, a bomb launching assembly 7 and a bomb pushing assembly 8.

[0057] Specifically, as shown in Figures 1 to 3 , the driving member 2 and the first guide rail 3 are fixedly arranged on the rack 1, wherein the bottom of the rack 1 is provided with a bomb launching opening 4, the grenade 6 is adapted to be launched outward from the bomb launching opening 4, and the bomb launching opening 4 is correspondingly arranged at the end of the first guide rail 3.

[0058] Specifically, as shown in Figures 1 to 4 , the bomb carrying assembly 5 is movably arranged on the first guide rail 3, the grenade 6 is adapted to be arranged on the bomb carrying assembly 5, and a plurality of grenades 6 are arranged at intervals along the length direction of the first guide rail 3. The bomb carrying assembly 5 comprises a second guide rail 501, the pull ring 601 of the grenade 6 is arranged on the second guide rail 501, and the pull ring 601 is adapted to move along the length direction of the second guide rail 501. The second guide rail 501 is arranged in parallel with the first guide rail 3, so that the pull ring 601 on the grenade 6 moves along the second guide rail 501 synchronously in the process of moving along the first guide rail 3.

[0059] Specifically, as shown in Figure 2 , the bomb launching assembly 7 is connected with the driving member 2, the driving member 2 is used to drive the bomb launching assembly 7 to apply a pushing force to the grenade 6 in the direction of the bomb launching opening 4, so that the grenade 6 completes the pull ring 601 and launching actions. Specifically, the direction of the pushing force can be perpendicular to the length direction of the second guide rail 501, so as to separate the grenade body and the pull ring 601 of the grenade 6 under the action of the pushing force.

[0060] Specifically, as shown in Figure 3 The driving member 2 is connected with the pusher assembly 8, and the driving member 2 is used to drive the pusher assembly 8 to push the carrier assembly 5 to move towards the direction of the launching port 4, so that the grenades 6 on the carrier assembly 5 are automatically supplemented to the launching port 4, and automatic feeding is realized.

[0061] Specifically, in order to reduce the weight of the automatic launching device, lightweight materials can be used, for example, carbon fiber plates or aluminum alloy materials are used.

[0062] The automatic launching device can install a plurality of grenades 6 on the carrier assembly 5 along the length direction of the first guide rail 3, and through the movement of the carrier assembly 5 in the length direction of the first guide rail 3, the grenades 6 on the carrier assembly 5 move towards the direction of the launching port 4, so as to improve the carrying capacity and automatic feeding of the automatic launching device. The pull ring 601 of the grenade 6 is movably arranged on the second guide rail 501, and the carrier assembly 5 moves along the first guide rail 3, and at the same time, the grenade 6 moves along the first guide rail 3, at this time, the pull ring 601 on the grenade 6 moves synchronously on the second guide rail 501 along with the grenade 6, until the grenade 6 moves to the launching port 4, the driving member 2 drives the launching assembly 7 to apply a pushing force to the grenade 6 towards the direction of the launching port 4, because the pull ring 601 of the grenade 6 is limited in the second guide rail 501, the launching assembly 7 separates the grenade body from the pull ring 601 in the process of pushing the grenade 6, and the action of the pull ring 601 is completed, when the pull ring 601 is separated from the grenade body, the grenade body falls from the launching port 4, and the launching action of the grenade 6 is completed. The driving member 2 drives the pusher assembly 8 to push the carrier assembly 5 to move towards the direction of the launching port 4, so that the grenades 6 on the carrier assembly 5 are automatically supplemented to the launching port 4, and automatic feeding is realized. The automatic launching device in the embodiment can realize automatic feeding of the grenades 6, automatic launching, automatic feeding, and further improve the launching efficiency of the automatic launching device.

[0063] The grenades 6 are loaded on the carrier assembly 5, and the carrier assembly 5 drives the grenades 6 to move along the first guide rail 3, that is, automatic feeding is realized, and the positioning of the grenades 6 is realized, because the pull ring 601 of the grenade 6 is limited by the second guide rail 501, the positioning of the grenade 6 is realized, and the phenomenon of rotation of the grenade 6 in the movement process is avoided.

[0064] Specifically, as shown in Figure 4As shown, the fixed part 10 can be arranged on the pull ring 601 of the grenade 6, and the fixed part 10 is clamped in the second guide rail 501, so that the fixed part 10 and the pull ring 601 can move together along the direction of the second guide rail 501. When the bomb throwing assembly 7 pushes the bomb body of the grenade 6, the pull ring 601 fixed with the fixed part 10 is also limited by the second guide rail 501, that is, when the bomb throwing assembly 7 pushes the bomb body of the grenade 6, the bomb body of the grenade 6 can be separated from the pull ring 601, and the action of the pull ring 601 of the grenade 6 is completed. Alternatively, a movable hook corresponding to the pull ring 601 is arranged in the second guide rail 501, which also has the function of limiting the pull ring 601, so that the pull ring 601 only moves along the second guide rail 501, so as to facilitate the subsequent separation of the pull ring 601 and the bomb body of the grenade 6. The embodiment of the present application does not specifically limit the cooperation between the pull ring 601 and the second guide rail 501.

[0065] Specifically, according to the structure of the automatic throwing device, the type of the driving part 2 is different. The driving part 2 can be a motor or a pneumatic cylinder. The type of the driving part 2 is not specifically limited in the embodiment of the present application.

[0066] In one embodiment, in combination with Figure 2 , Figure 3 and Figure 7 As shown, the bomb throwing assembly 7 includes a push block 701 and a guide part 702. The guide part 702 is arranged on the rack 1, and the push block 701 is movably arranged on the guide part 702 and guided in the moving direction by the guide part 702. The push block 701 has a bomb pushing state and a bomb loading state. From the bomb loading state to the bomb pushing state, the driving part 2 drives the push block 701 to move along the guide part 702 towards the grenade 6, so that the push block 701 applies a pushing force to the grenade 6 in the direction of the bomb throwing port 4, and then the bomb body of the grenade 6 is separated from the pull ring 601, and the bomb body of the grenade 6 is pushed to the bomb throwing port 4, and the throwing action of the grenade 6 is completed. From the bomb pushing state to the bomb loading state, the driving part 2 drives the push block 701 to move along the guide part 702 away from the grenade 6. At this time, the push block 701 can place the grenade 6 below, and the bomb throwing assembly 8 can push the grenade 6 on the bomb loading assembly 5 to the bottom of the push block 701. It can be understood that the bomb body of the grenade 6 is pushed by the driving part 2 driving the push block 701 to move downward along the guide part 702, so that the grenade 6 is thrown to the bomb throwing port 4, or the push block 701 is driven to move upward along the guide part 702, so that the grenade 6 on the bomb loading assembly 5 is automatically replenished to the bottom of the push block 701, in order to prepare for the next throwing of the grenade 6 and improve the throwing efficiency of the automatic throwing device. Moreover, the push block 701 and the guide part 702 have simple structure and convenient operation.

[0067] It should be noted that the structure of the push block 701 and the guide 702 is not specifically limited in the embodiments of the present application. For example, a guide groove is arranged on the push block 701, a guide rail is arranged on the guide 702 corresponding to the guide groove, and the guide groove is arranged in the guide rail. Alternatively, a guide rail is arranged on the push block 701, a guide groove is arranged on the guide 702 corresponding to the guide rail, and the guide groove is arranged in the guide rail.

[0068] In one embodiment, as shown in Figure 7 The bomb-throwing assembly 7 further includes a first connecting rod 703 and a second connecting rod 704. One end of the first connecting rod 703 is connected to the driving end of the driving member 2, the other end of the first connecting rod 703 is hingedly connected to one end of the second connecting rod 704, and the other end of the second connecting rod 704 is hingedly connected to the push block 701. The rotation of the driving member 2 drives the rotation of the first connecting rod 703, which in turn drives the swing of the second connecting rod 704 hingedly connected to the first connecting rod 703. During the swing of the second connecting rod 704, the other end of the second connecting rod 704 drives the push block 701 to move up and down along the guide 702. The driving of the first connecting rod 703 and the second connecting rod 704 by the driving member 2 drives the push block 701 to move up and down, reduces the pause gap of the push block 701 during reciprocating movement, improves the bomb-throwing efficiency of the push block 701, and further improves the throwing efficiency of the automatic throwing device.

[0069] In one embodiment, as shown in Figures 2 to 5 The bomb-carrying assembly 5 includes a bomb chain component 502, which includes a plurality of support rods 5021 and a connecting rod 5022. The plurality of support rods 5021 are arranged at intervals along the length direction of the first guide rail 3, and a placement groove suitable for placing a grenade 6 is formed between any two adjacent support rods 5021. The two ends of the connecting rod 5022 are hingedly connected to the end portions of any two adjacent support rods 5021. By arranging a plurality of support rods 5021 at intervals, a placement groove for placing a grenade 6 is formed between any two adjacent support rods 5021. By placing a grenade 6 in the placement groove, the grenade 6 is clamped in the placement groove under the action of its own gravity, thereby limiting the grenade 6, avoiding the movement or rotation of the grenade 6 on the bomb chain component 502, and ensuring that the grenades 6 can enter the bomb-throwing opening 4 one by one under the action of the movement of the bomb chain component 502.

[0070] The two adjacent support rods 5021 are connected by a connecting rod 5022, and the end of the connecting rod 5022 is hingedly arranged with the support rod 5021, that is, the link assembly 502 can be rolled into a roll to facilitate the carrying of the link assembly 502, and when the link assembly 502 enters the position of the launching port 4, the link assembly 502 at the launching port 4 extends out of the first guide rail 3, at this time, the link assembly 502 at the launching port 4 is not supported by the first guide rail 3, and under the influence of its own gravity, the link assembly 502 at the launching port 4 will appear to fall downward, and cannot provide support for the grenade 6 at the launching port 4, so as to ensure that the grenade 6 at the launching port 4 can be smoothly launched from the launching port 4.

[0071] Specifically, as shown in Figure 5 , the position where the support rod 5021 contacts the grenade 6 can be provided with a protruding support portion, so that the support rod 5021 provides better support effect for the grenade 6, and avoids rotation of the grenade 6 during movement.

[0072] Specifically, as shown in Figure 5 , the two ends of the support rod 5021 can also be provided with a roller, and the roller is arranged in the first guide rail 3. During movement of the link assembly 502 along the first guide rail 3, the roller rotates in the first guide rail 3, reduces the friction between the link assembly 502 and the first guide rail 3, so as to facilitate sliding of the link assembly 502 on the first guide rail 3, and improve the smoothness of feeding.

[0073] In one embodiment, the grenade feeding assembly 5 further comprises a connecting line, one end of the connecting line is connected with the link assembly 502, and the other end of the connecting line is connected with the rack 1. The link assembly 502 and the rack 1 are connected through the connecting line, so that the link assembly 502 and the rack 1 are always connected, avoiding falling of the link assembly 502, ensuring that the link assembly 502 can be reused, and reducing waste.

[0074] It should be noted that the type and connection method of the connecting line are not limited in detail in the embodiment. For example, the connecting line can be a steel wire, one end of which is tied to the link assembly 502, and the other end is tied to the rack 1. Or a through hole is arranged on the link assembly 502, and the steel wire is fixed at one end of the through hole and the link assembly 502, and the other end is fixed with the rack 1. The connecting line can also be other metal connecting lines.

[0075] In one embodiment, in combination with Figure 2 , Figure 3 and Figure 6As shown, the bullet pushing assembly 8 comprises a third guide rail 801 and a bullet pushing trolley 802, the third guide rail 801 is fixedly arranged on the frame 1, the third guide rail 801 is arranged along the length direction of the first guide rail 3, the bullet pushing trolley 802 is movably arranged on the third guide rail 801, the bullet pushing trolley 802 is rotatably arranged with a bullet pushing member 8021, the bullet pushing trolley 802 is connected with the driving member 2, the driving member 2 drives the bullet pushing trolley 802 to move along the third guide rail 801, and the bullet pushing trolley 802 has a first state and a second state.

[0076] From the first state to the second state, the driving member 2 drives the bullet pushing trolley 802 to move along the third guide rail 801 towards the direction away from the bullet throwing port 4, in the process of moving of the bullet pushing trolley 802, the bullet pushing member 8021 rotates to the upper side of the grenade 6, so that the bullet pushing member 8021 passes the grenade 6 in the process of moving of the bullet pushing trolley 802. In this process, the bullet pushing trolley 802 moves towards the direction away from the bullet throwing port 4, and the bullet loading assembly 5 does not move.

[0077] From the second state to the first state, the bullet pushing member 8021 is located between the adjacent two grenades 6, the driving member 2 drives the bullet pushing trolley 802 to move along the third guide rail 801 towards the direction of the bullet throwing port 4, and the bullet pushing member 8021 pushes the grenade 6. In this process, the bullet pushing trolley 802 moves towards the direction close to the bullet throwing port 4, and since the bullet pushing member 8021 is located between the adjacent two grenades 6, the bullet pushing member 8021 moves together with the bullet pushing trolley 802 in the process of moving of the bullet pushing trolley 802, and the bullet pushing member 8021 drives the grenade 6 to move towards the bullet throwing port, so as to realize automatic feeding.

[0078] Through the bullet pushing trolley 802 driving the bullet pushing member 8021 to move along the third guide rail 801, in the process from the first state to the second state, the bullet pushing trolley 802 moves towards the direction away from the bullet throwing port 4, and the bullet loading assembly 5 does not move, at this time, it is in the preparation feeding link, in the process from the second state to the first state, the bullet pushing trolley 802 moves towards the direction close to the bullet throwing port 4, and drives the grenade 6 and the chain component 502 to move towards the direction of the bullet throwing port 4, so as to realize automatic feeding, and the feeding efficiency is high.

[0079] In one embodiment, as shown, Figure 6 The bullet pushing trolley 802 is provided with a rotating shaft 8022, one end of the bullet pushing member 8021 is rotatably arranged on the rotating shaft 8022, the side wall of the bullet pushing trolley 802 is provided with a limiting member 8023, and the end of the bullet pushing member 8021 close to the rotating shaft 8022 is provided with a protruding portion 80211 corresponding to the limiting member 8023.

[0080] From the first state to the second state, the protruding part 80211 is away from the limiting part 8023, and the pusher 8021 is arranged in parallel with the moving plane of the pusher trolley 802. In the process of moving from the first state to the second state, the pusher 8021 first contacts the grenade 6 on the grenade component 502, the grenade 6 applies an upward thrust to the pusher 8021, so that the pusher 8021 rotates upward relative to the grenade 6, and then the plane where the pusher 8021 is located is parallel to the moving plane of the pusher trolley 802. At this time, in the process of moving the pusher trolley towards the direction away from the launching port 4, the pusher 8021 cannot push the grenade 6.

[0081] From the second state to the first state, the protruding part 80211 abuts against the limiting part 8023, and the pusher 8021 is arranged obliquely with the moving plane of the pusher trolley 802. In the process of moving from the first state to the second state, in the second state, the pusher 8021 is located between the two grenades 6, the pusher 8021 is affected by its own gravity, and the pusher 8021 rotates downward, so that the pusher 8021 enters the gap between the two grenades 6. When the pusher trolley 802 moves towards the launching port 4, the pusher 8021 moves together with the pusher trolley 802, and the pusher 8021 applies a thrust to the grenade 6 towards the launching port 4, and the protruding part 80211 abuts against the limiting part 8023, so that the pusher 8021 cannot rotate, that is, the pusher 8021 pushes the grenade 6 to move towards the launching port 4, and completes the automatic feeding.

[0082] Through the cooperation of the protruding part 80211 and the limiting part 8023, in the process of moving the pusher trolley 802 from the second state to the first state, the pusher can push the grenade 6 towards the launching port 4, and automatic feeding is realized, and the structure is ingenious.

[0083] In one embodiment, as shown in Figure 8 The pusher assembly 8 further includes a first movable pulley 803, a first fixed pulley 804, a second fixed pulley 805, a third fixed pulley 806 and a first driving belt 807. The first fixed pulley 804, the second fixed pulley 805 and the third fixed pulley 806 are arranged on the rack 1, the first movable pulley 803 is fixedly arranged on the push block 701, and the first movable pulley 803 is arranged between the first fixed pulley 804 and the second fixed pulley 805. In the process of moving the push block 701 up and down, the first movable pulley 803 can move up and down together.

[0084] One end of the first driving belt 807 is fixedly arranged on the first fixed pulley 804, and the other end is fixedly arranged on the pusher trolley 802. The first driving belt 807 respectively contacts the top of the first fixed pulley 804, the second fixed pulley 805 and the third fixed pulley 806, and the bottom of the first movable pulley 803.

[0085] By setting the first movable pulley 803 on the push block 701, the push block 701 is moved from the upper ejection state to the push ejection state, that is, the push block 701 is moved downward to the ejection opening 4, the pull ring 601 and the ejection action are completed, and the push block 701 is moved downward while driving the first movable pulley 803 to move downward, at this time, the first movable pulley 803 presses the first driving belt 807 between the first fixed pulley 804 and the second fixed pulley 805, so that the first driving belt 807 pulls the push ejection trolley 802 into the second state, and prepares for ejection. While the push block 701 pushes the grenade 6, the push block 701 drives the push ejection trolley 802 into the second state, thereby improving the ejection efficiency of the automatic ejection device.

[0086] Specifically, a tensioning pulley can be arranged between the second fixed pulley 805 and the third fixed pulley 806 to tension the first driving belt 807.

[0087] In one embodiment, as shown in Figure 8 The push ejection assembly 8 further comprises a second movable pulley 808, a fourth fixed pulley 809, a fifth fixed pulley 810 and a second driving belt 811, the fourth fixed pulley 809 and the fifth fixed pulley 810 are arranged on the rack 1, the second movable pulley 808 is fixedly arranged on the push block 701, and the second movable pulley 808 is arranged between the fourth fixed pulley 809 and the fifth fixed pulley 810.

[0088] One end of the second driving belt 811 is fixedly arranged on the fourth fixed pulley 809, and the other end is fixedly arranged on the push ejection trolley 802, the second driving belt 811 is in contact with the bottom of the fourth fixed pulley 809 and the fifth fixed pulley 810 respectively, and the second driving belt 811 is in contact with the top of the second movable pulley 808.

[0089] By setting the second movable pulley 808 on the push block 701, the push block 701 is moved from the push ejection state to the upper ejection state, that is, the push block 701 is moved upward away from the ejection opening 4, and the push block 701 is moved upward while driving the second movable pulley 808 to move upward, at this time, the second movable pulley 808 pulls the second driving belt 811 between the fourth fixed pulley 809 and the fifth fixed pulley 810, so that the second driving belt 811 pulls the push ejection trolley 802 into the first state, the push ejection piece 8021 drives the grenade 6 to move toward the push ejection opening, and the automatic ejection is realized. While the push block 701 is moved upward, the push block 701 drives the push ejection trolley 802 into the first state, thereby improving the ejection efficiency of the automatic ejection device.

[0090] The working principle of the automatic ejection device in the embodiment of the application is described as follows:

[0091] 1) The grenade 6 is loaded into the automatic ejection device:

[0092] First, place one end of the ammunition belt component 502 on the first guide rail 3, then place the grenade 6 on the placement slot between two adjacent support rods 5021, and restrict the pull ring 601 of the grenade 6 on the second guide rail 501. Then, in the same manner, install subsequent grenades 6 on the ammunition belt component 502 and the second guide rail 501.

[0093] 2) Driven by drive component 2, the first link 703 and the second link 704 move the push block 701 up and down:

[0094] like Figure 7 As shown, the rotation of the drive component 2 drives the first link 703 to rotate, and the rotation of the first link 703 in turn drives the second link 704, which is hinged to the first link 703, to swing. During the swing of the second link 704, the other end of the second link 704 drives the push block 701 to move up and down along the guide component 702, thereby realizing the switching of the push block 701 between the spring-up state and the spring-pushing state.

[0095] 3) Push block 701 moves from the loading state to the pushing state, simultaneously driving the pushing trolley 802 from the first state to the second state:

[0096] From the loading state to the throwing state, the drive unit 2 drives the push block 701 to move along the guide member 702 toward the grenade 6, so that the push block 701 applies a pushing force to the grenade 6 toward the throwing port 4, thereby separating the grenade body from the pull ring 601 and pushing the grenade body toward the throwing port 4, completing the throwing action of the grenade 6. As the push block 701 moves downward, it also drives the first movable pulley 803 to move downward. At this time, the first movable pulley 803 presses down on the first drive belt 807 between the first fixed pulley 804 and the second fixed pulley 805, so that the first drive belt 807 pulls the throwing trolley 802 into the second state, ready to feed the grenade.

[0097] 4) Push block 701 moves from the pusher state to the loading state, simultaneously driving pusher trolley 802 from the second state to the first state:

[0098] From the grenades-pushing state to the grenade-loading state, the pusher block 701 moves along the guide 702 away from the grenade 6. At this time, the grenade 6 can be placed below the pusher block 701, and the grenade-pushing assembly 8 can push the grenade 6 on the grenade-carrying assembly 5 to below the pusher block 701. The pusher block 701 moves upward away from the grenade-throwing port 4. As the pusher block 701 moves upward, it also drives the second movable pulley 808 to move upward. At this time, the second movable pulley 808 pulls the second drive belt 811 between the fourth fixed pulley 809 and the fifth fixed pulley 810, so that the second drive belt 811 pulls the grenade-pushing trolley 802 into the first state. The grenade-pushing component 8021 drives the grenade 6 towards the grenade-pushing port to realize automatic grenade feeding.

[0099] According to the embodiment of the present application, in another aspect, there is also provided a UAV, a UAV body and an automatic launching device. The rack 1 is provided with a connecting piece 9, which is detachably connected with the UAV body.

[0100] The UAV, by installing the automatic launching device on the UAV body through the connecting piece 9, can improve the mobility, projection range, launching precision and striking efficiency of the active service riot grenade 6 by taking advantage of the rapid maneuvering, situation awareness and other advantages of the aerial UAV.

[0101] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
