Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and in particular relates to an automatic grenade throwing device carried by an unmanned aerial vehicle. Background Art

[0002] A hand grenade is a small hand-thrown ammunition that can be used for both offense and defense. It is also a widely used and large-volume ammunition. It can kill living targets and destroy tanks and armored vehicles. Drones are becoming more and more commonly used in the military field. They can perform tasks such as reconnaissance and strikes. Because of their mobility and flexibility and the advantage of non-contact combat, they are one of the driving forces for the birth of new combat modes. Therefore, combining drones with the classic weapon system of hand grenades not only retains the powerful killing effectiveness of grenades, but also gives them unprecedented remote control capabilities.

[0003] In the Chinese patent with publication number CN107514933B, a drone grenade throwing device is mentioned, which overcomes the limitation of manual throwing, expands the flexibility of use, improves safety, takes into account the safety issues in the grenade throwing process, and ensures the safety of the grenade throwing process through the cooperation of the safety release mechanism and the magazine door unlocking mechanism; however, the bomb placement tube in the bomb throwing device is directly installed on the drone's bracket. This rigid connection cannot effectively buffer or offset these unstable factors when the drone encounters airflow disturbances and self-swaying during flight. Therefore, the grenade is not only affected by the preset ejection force at the moment of ejection, but also additionally bears the dynamic influence from the shaking of the drone, which greatly challenges the stability of the grenade during the ejection process. The lack of stability directly leads to the difficulty in predicting the ejection trajectory of the grenade, thereby reducing its ejection accuracy, which may cause deviations when hitting the target, affecting the overall combat effect;

[0004] In addition, during the use of the grenade launching device, since the grenade placement tube is directly and fixedly installed on the drone's bracket, the angle of the grenade during the ejection process is fixed and difficult to adjust, which in turn limits the application scope of the grenade. It is difficult to flexibly adjust the ejection angle to meet combat needs in different terrain conditions and when facing a variety of targets, reducing its practicality. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] See also Figure 1 - Figure 4 As shown, a grenade automatic throwing device carried by a drone comprises:

[0032] Shock mount 1;

[0033] The shock absorbing mechanism 2 includes a shock absorbing box 21, a limiting rod 22, a shock absorbing spring 23, a shock absorbing plate 24 and a buffer mechanism 25. The shock absorbing box 21 is installed at the top of the shock absorbing frame 1. Four limiting rods 22 are provided, and the four limiting rods 22 are respectively installed at the four inner corners of the shock absorbing box 21. The shock absorbing spring 23 is sleeved on the outer surface of the limiting rod 22. The shock absorbing plate 24 is installed between the middle parts of the outer surfaces of the four limiting rods 22. Two buffer mechanisms 25 are provided, and the two buffer mechanisms 25 are respectively installed at the top and bottom of the shock absorbing plate 24;

[0034] The adjusting mechanism 4 is installed at the lower part of the outer wall of the shock absorbing frame 1, and the adjusting mechanism 4 can adjust the throwing angle of the grenade.

[0035] Depend on Figure 1 - Figure 3 It can be seen that a drone rack 3 is installed on the top of the shock absorbing mechanism 2, an automatic grenade throwing chamber 5 is installed on the inner side of the adjusting mechanism 4, and an electric chamber door 6 is installed on the bottom of the automatic grenade throwing chamber 5;

[0036] The buffer mechanism 25 includes a buffer 251, a buffer plate 252, an elastic sheet 253 and a magnetic block 254. Two buffer plates 252 are provided, and the opposite surfaces of the two buffer plates 252 are respectively installed on the top of the shock absorbing plate 24 and the box wall of the shock absorbing box 21. The buffer 251 is installed between the middle parts of the opposite surfaces of the two buffer plates 252. There are a plurality of elastic sheets 253 and a plurality of magnetic blocks 254, and the plurality of elastic sheets 253 are respectively installed on the four sides of the opposite surfaces of the two buffer plates 252, and the plurality of magnetic blocks 254 are respectively installed at the four corners of the opposite surfaces of the two buffer plates 252.

[0037] As can be seen from the above, first, the drone bracket 3 is installed on the drone, so that the entire throwing device can be carried by the drone. When the drone encounters airflow disturbance and self-swaying during flight, the shock-absorbing plate 24 drives the shock-absorbing frame 1 to move up and down on the limit rod 22, and then the elasticity of the shock-absorbing spring 23 can be used to dampen the vibration caused by the shaking. At the same time, the elastic deformation of the arc-shaped elastic sheet 253 and the repulsive force generated by the magnetic block 254 due to the same magnetic poles can be used to buffer and dampen the vibration of the grenade automatic throwing bin 5 again. Finally, the damping characteristics of the buffer 251 can suppress the repeated rebound of the shock-absorbing spring 23, which can effectively buffer or offset these unstable factors, thereby improving the stability of the grenade during the ejection process, making the ejection trajectory of the grenade predictable, and avoiding deviations when hitting the target, thereby ensuring the accuracy of the grenade ejection and improving the overall combat effect.

[0038] Specifically, refer to Figure 1 - Figure 3 As shown, the shock absorber frame 1 is configured as an H-shaped structure, and the top end of the shock absorber frame 1 passes through the bottom end of the shock absorber box 21 and is installed on the bottom end of the shock absorber plate 24; a plurality of elastic sheets 253 are configured as arc structures, and the opposite surfaces of two adjacent elastic sheets 253 contact each other, and the magnetic poles of the magnetic blocks 254 installed on the two buffer plates 252 are the same.

[0039] As can be seen from the above, the H-shaped shock absorbing frame 1 can enhance its structural strength, and the installation between the shock absorbing frame 1 and the shock absorbing plate 24 enables the shock absorbing frame 1 to perform shock absorbing operation as the shock absorbing plate 24 moves; the arc-shaped elastic sheet 253 can have a certain deformation buffering ability, and the same magnetic poles make the magnetic blocks 254 on the two buffer plates 252 generate repulsive forces against each other.

[0040] Embodiment 2:

[0041] refer to Figure 4 As shown, the adjustment mechanism 4 includes an adjustment frame 41, an adjustment shaft 42, an adjustment gear 43, a protective cover 44, an electric push rod 45 and an adjustment rack 46. The adjustment frame 41 is installed on the upper outer surface of the grenade automatic throwing chamber 5. Two adjustment shafts 42, adjustment gears 43, protective cover 44, electric push rod 45 and adjustment rack 46 can be provided. Two adjustment shafts 42 are respectively installed on both sides of the outer wall of the adjustment frame 41, two adjustment gears 43 are respectively installed on the outer surfaces of the two adjustment shafts 42, two protective covers 44 are respectively installed on the opposite sides of the two adjustment shafts 42, two electric push rods 45 are respectively installed on the top ends of the two protective covers 44, and two adjustment racks 46 are respectively installed on the output ends of the two electric push rods 45.

[0042] As can be seen from the above, when it is necessary to throw a grenade, the electric push rod 45 can be started, and the push-pull movement of the adjustment rack 46 can be achieved through the extension and retraction of the electric push rod 45. At this time, by adjusting the meshing transmission between the rack 46 and the adjustment gear 43, the adjustment shaft 42 drives the adjustment frame 41 to rotate, so that the adjustment frame 41 drives the automatic grenade throwing chamber 5 to rotate stably, and the angle of the grenade during the ejection process can be adjusted, thereby expanding the application range of the grenade. When the angle of the automatic grenade throwing chamber 5 is adjusted, the electric chamber door 6 can be opened, so that the automatic grenade throwing chamber 5 throws the grenade inside out, so that the throwing device can flexibly adjust the ejection angle to meet combat needs under different terrain conditions and facing diverse targets, and also improves the practical performance of the throwing device.

[0043] Preferably, reference Figure 4 As shown, the side of the adjustment frame 41 is set as a T-shaped structure, and the outer surface of the adjustment gear 43 is meshed with the outer surface of the adjustment rack 46; the distance between the top end of the electric push rod 45 and the bottom end of the shock absorber box 21 is greater than the height of the buffer 251, and the bottom end of the adjustment rack 46 passes through the lower wall of the protective cover 44.

[0044] As can be seen from the above, the contact area between the adjustment frame 41 and the automatic grenade throwing chamber 5 can be increased, so that the adjustment frame 41 and the automatic grenade throwing chamber 5 are firmly connected, and the adjustment gear 43 can be driven to rotate by the adjustment rack 46; the electric push rod 45 is placed within the buffering range of the buffer 251 and does not contact the shock absorber box 21, so as not to affect the buffering of the buffer 251, and the protective cover 44 can limit and protect the adjustment rack 46.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
