Description

Technical Field

[0001] The present invention belongs to the technical field of weapon systems, and specifically relates to a small ammunition airdrop mechanism, and in particular to a mechanism suitable for small ammunition aerial gravity delivery. The structure realizes aerial gravity delivery of small ammunition on the basis of combining portability, reliability, and multi-platform adaptability. Background Art

[0002] Ammunition is the core part of the weapon system and is the ultimate means to complete the given combat mission by launching it to the target area with the help of weapons (or other delivery platforms).

[0003] Small ammunition is favored by the military of various countries in the world due to its small size, light weight, mobility and low cost. The main scenes of modern warfare are generally urban warfare, special operations and reverse slope warfare, which require taking into account the needs of ground weapon launch and aerial platform delivery at the same time. Therefore, whether it is possible to realize the air delivery of small ammunition on the basis of integrated design, so that the ammunition can be carried by the flying platform into the combat area and quickly perform combat missions after being dropped from the air has become a key factor in determining the combat effectiveness of small ammunition.

[0004] At present, conventional airdrop mechanisms require complex structures and electrical systems, are heavy, inconvenient to install, have poor platform compatibility, complex operation procedures, and long preparation time, which seriously restricts the combat effectiveness of small ammunition. Therefore, it is urgent to develop a small ammunition airdrop mechanism that is simple to operate, light in weight, and highly adaptable. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] The technical problem to be solved by the present invention is: how to provide a small ammunition airdrop mechanism which is simple to operate, light in weight, has reliable mechanism actuation, and can be applied to multiple platforms, so as to solve a series of problems of conventional airdrop mechanisms, such as long preparation time, large weight, complicated operation process, and inability to adapt to multiple platforms.

[0007] (II) Technical solution

[0008] In order to solve the above technical problems, the present invention provides a small ammunition airdrop mechanism, which comprises: a base plate (1), a ring seat (2), a ring (3), a rotating shaft (4), a latch (5), a latch support (6), a connecting rod (7), a steering gear (8), a rocker arm (9), and an adapter block (10);

[0009] The general assembly diagram of the airdrop mechanism (locked state) is as follows: Figure 1As shown, the base plate (1) and the flying platform are reliably fixed by bolts. According to the maximum working condition during use, the strength of the bolt connection is locally strengthened during design, which can better ensure the reliable fixation of the base and the flying platform. The two holding ring seats (2) are the main bearing bodies and are installed at both ends of the base plate (1) by bolts. The two sets of holding rings (3) adopt a split design and are installed on the holding ring seats (2) through the rotating shaft (4) through the mounting holes. The rotating shaft (4) and the holding ring (3) adopt a clearance fit to ensure that the holding ring (3) can rotate along the rotating shaft (4). The latch (5) is inserted into another positioning hole of the holding ring seat (2) and the holding ring (3) to lock the holding ring (3). To ensure that the latch (5) can be accurately positioned, the latch support (6) is installed on the bottom plate (1) by screws, and the latch (5) is rotated through the positioning hole thereon, so that the latch (5) can only move axially. The latch is a "U-shaped" structure, and the other end of the latch is connected to the connecting rod (7) by a hinge. The other end of the connecting rod (7) is connected to the rocker arm (9) fixed on the steering gear (8) by a hinge. At this time, the steering gear (8) is in a locked state and is installed on the bottom plate (1) by screws. At this point, the assembly of the entire airdrop mechanism is completed.

[0010] The two holding rings (3) are arranged in pairs and are used to fit tightly against the outer wall of the ammunition to limit the radial movement of the ammunition, while limiting the axial movement and rotation of the ammunition through friction.

[0011] In order to ensure that the holding ring (3) is reliably fixed, each holding ring (3) passes through a positioning hole in the holding ring seat (2) via a rotating shaft (4) and a latch (5). At the same time, in order to ensure the limiting accuracy of the latch (5), the latch (5) is guided by a latch support (6) before being inserted into the holding ring (3). In this way, each holding ring (3) is limited by two points, ensuring that the ammunition and the holding ring (3) cannot move relative to each other, thereby realizing the locking function of the ammunition on the throwing mechanism.

[0012] The adapter block (10) is arranged on the inner side of the holding ring (3) to adapt to different outer contours, and the friction coefficient can also be increased through the flexible adjustment pad.

[0013] Among them, Figure 2 The figure shows the schematic diagram of the airdrop mechanism mounting ammunition. When the flying platform arrives at the combat area and is ready to airdrop ammunition, the steering gear (8) rotates after receiving the control signal under the action of the control signal, driving the connecting rod (7) to move along the axial direction of the ammunition. The connecting rod (7) drives the pin (5) to be pulled out from the locking hole of the holding ring, releasing the holding ring limit, and the ammunition falls under the action of gravity, completing the airdrop (such as Figure 3 shown).

[0014] The ammunition throwing function of the airdrop mechanism is: driven by a steering gear (8), driving the rocker arm (9) to rotate, driving the two groups of connecting rods (7) to simultaneously pull the latch (5) out of the two groups of holding rings (3); wherein the rocker arm (9), the connecting rod (7) and the latch (5) are all connected by hinges; thus, the synchronization of the release of the two groups of holding rings (3) is ensured. At this time, after the latch (5) is pulled out, the holding ring (3) is only constrained by the rotating shaft (4), and under the action of gravity, the ammunition simultaneously opens the two groups of holding rings (3) along the rotating shaft (4) and is completely separated from the throwing mechanism, thereby realizing the throwing function of the ammunition.

[0015] The multi-platform adaptability of the airdrop mechanism is as follows: first, the main body of the mechanism connection and load-bearing is the bottom plate (1), and a plurality of mounting holes are reserved on the bottom plate (1), which is fastened with various flight platforms by bolts and nuts, and the mechanical connection is convenient;

[0016] Among them, the airdrop mechanism has no pyrotechnics and is electrically driven by a single servo, and has strong electrical adaptability.

[0017] The airdrop mechanism has a simple structure and is made of lightweight and high-strength composite materials and aluminum alloy materials. In short, the airdrop mechanism has strong multi-platform adaptability.

[0018] The bottom plate (1) is a main body for connecting the mechanism and bearing the load, and is formed by winding a Kevlar fiber composite material, which has high specific strength and light weight.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention ingeniously achieves the locking and ejection of ammunition by driving the double-link mechanism with a single servo, while also ensuring the consistency of the disengagement of the two sets of rings, greatly reducing the initial disturbance when the ammunition is dropped. The present invention has the advantages of light weight, simple structure, high separation reliability, and strong platform adaptability, and can reliably throw various types of ammunition.

[0023] Figure 3 It is a schematic diagram of the airdrop mechanism of the present invention dropping ammunition (after unlocking). DETAILED DESCRIPTION

[0024] In order to make the purpose, content, and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings and examples.

[0025] In order to solve the above technical problems, the present invention provides a small ammunition airdrop mechanism, which comprises: a base plate (1), a ring seat (2), a ring (3), a rotating shaft (4), a latch (5), a latch support (6), a connecting rod (7), a steering gear (8), a rocker arm (9), and an adapter block (10);

[0026] The general assembly diagram of the airdrop mechanism (locked state) is as follows: Figure 1 As shown, the base plate (1) and the flying platform are reliably fixed by bolts. According to the maximum working condition during use, the strength of the bolt connection is locally strengthened during design, which can better ensure the reliable fixation of the base and the flying platform. The two holding ring seats (2) are the main bearing bodies and are installed at both ends of the base plate (1) by bolts. The two sets of holding rings (3) adopt a split design and are installed on the holding ring seats (2) through the rotating shaft (4) through the mounting holes. The rotating shaft (4) and the holding ring (3) adopt a clearance fit to ensure that the holding ring (3) can rotate along the rotating shaft (4). The latch (5) is inserted into another positioning hole of the holding ring seat (2) and the holding ring (3) to lock the holding ring (3). To ensure that the latch (5) can be accurately positioned, the latch support (6) is installed on the bottom plate (1) by screws, and the latch (5) is rotated through the positioning hole thereon, so that the latch (5) can only move axially. The latch is a "U-shaped" structure, and the other end of the latch is connected to the connecting rod (7) by a hinge. The other end of the connecting rod (7) is connected to the rocker arm (9) fixed on the steering gear (8) by a hinge. At this time, the steering gear (8) is in a locked state and is installed on the bottom plate (1) by screws. At this point, the assembly of the entire airdrop mechanism is completed.

[0027] The two holding rings (3) are arranged in pairs and are used to fit tightly against the outer wall of the ammunition to limit the radial movement of the ammunition, while limiting the axial movement and rotation of the ammunition through friction.

[0028] In order to ensure that the holding ring (3) is reliably fixed, each holding ring (3) passes through a positioning hole in the holding ring seat (2) via a rotating shaft (4) and a latch (5). At the same time, in order to ensure the limiting accuracy of the latch (5), the latch (5) is guided by a latch support (6) before being inserted into the holding ring (3). In this way, each holding ring (3) is limited by two points, ensuring that the ammunition and the holding ring (3) cannot move relative to each other, thereby realizing the locking function of the ammunition on the throwing mechanism.

[0029] The adapter block (10) is arranged on the inner side of the holding ring (3) to adapt to different outer contours, and the friction coefficient can also be increased through the flexible adjustment pad.

[0030] Among them, Figure 2The figure shows the schematic diagram of the airdrop mechanism mounting ammunition. When the flying platform arrives at the combat area and is ready to airdrop ammunition, the steering gear (8) rotates after receiving the control signal under the action of the control signal, driving the connecting rod (7) to move along the axial direction of the ammunition. The connecting rod (7) drives the pin (5) to be pulled out from the locking hole of the holding ring, releasing the holding ring limit, and the ammunition falls under the action of gravity, completing the airdrop (such as Figure 3 shown).

[0031] The ammunition throwing function of the airdrop mechanism is: driven by a steering gear (8), driving the rocker arm (9) to rotate, driving the two groups of connecting rods (7) to simultaneously pull the latch (5) out of the two groups of holding rings (3); wherein the rocker arm (9), the connecting rod (7) and the latch (5) are all connected by hinges; thus, the synchronization of the release of the two groups of holding rings (3) is ensured. At this time, after the latch (5) is pulled out, the holding ring (3) is only constrained by the rotating shaft (4), and under the action of gravity, the ammunition simultaneously opens the two groups of holding rings (3) along the rotating shaft (4) and is completely separated from the throwing mechanism, thereby realizing the throwing function of the ammunition.

[0032] The multi-platform adaptability of the airdrop mechanism is as follows: first, the main body of the mechanism connection and load-bearing is the bottom plate (1), and a plurality of mounting holes are reserved on the bottom plate (1), which is fastened with various flight platforms by bolts and nuts, and the mechanical connection is convenient;

[0033] Among them, the airdrop mechanism has no pyrotechnics and is electrically driven by a single servo, and has strong electrical adaptability.

[0034] The airdrop mechanism has a simple structure and is made of lightweight and high-strength composite materials and aluminum alloy materials. In short, the airdrop mechanism has strong multi-platform adaptability.

[0035] The bottom plate (1) is a main body for connecting the mechanism and bearing the load, and is formed by winding a Kevlar fiber composite material, which has high specific strength and light weight.

[0036] Example 1

[0037] The airdrop mechanism of the present embodiment comprises: a base plate (1), an embracing ring seat (2), an embracing ring (3), a rotating shaft (4), a latch (5), a latch support (6), a connecting rod (7), a steering gear (8), a rocker arm (9), and an adapter block (10).

[0038] The general assembly diagram of the airdrop mechanism (locked state) is as follows: Figure 1As shown, the base plate (1) is the main body for connecting the mechanism and bearing the load, and is formed by winding a Kevlar fiber composite material, which has high specific strength and light weight. The base plate (1) and the flying platform are reliably fixed by bolts. According to the maximum working condition during use, the strength of the bolt connection is locally strengthened during the design, which can better ensure the reliable fixation of the base and the flying platform. The two holding ring seats (2) are the main bearing bodies and are installed at both ends of the base plate (1) by bolts. The two sets of holding rings (3) are designed in a split type and are installed on the holding ring seats (2) through the rotating shaft (4) through the mounting holes. The rotating shaft (4) and the holding ring (3) are clearance-matched to ensure that the holding ring (3) can rotate along the rotating shaft (4). Subsequently, the latch (5) is inserted into another positioning hole of the holding ring seat (2) and the holding ring (3) to lock the holding ring. To ensure that the latch (5) can be accurately positioned, the latch support (6) is installed on the bottom plate (1) by screws, and the latch (5) is rotated through the positioning hole thereon, so that the latch (5) can only move axially. The latch is a "U-shaped" structure, and its other end is connected to the connecting rod (7) by a hinge. The other end of the connecting rod (7) is connected to the rocker arm (9) fixed on the steering gear (8) (which is in a locked state at this time and is installed on the bottom plate (1) by screws) by a hinge. At this point, the entire airdrop mechanism is assembled.

[0039] like Figure 2 The figure shows the schematic diagram of the airdrop mechanism mounting ammunition. When the flying platform arrives at the combat area and is ready to airdrop ammunition, the steering gear (8) rotates after receiving the control signal under the action of the control signal, driving the connecting rod (7) to move along the axial direction of the ammunition. The connecting rod (7) drives the pin (5) to be pulled out from the locking hole of the holding ring, releasing the holding ring limit, and the ammunition falls under the action of gravity, completing the airdrop (such as Figure 3 shown).

[0040] The present invention has been successfully applied to a certain type of ammunition weapon system. After multiple tests carried out with the weapon system, it has been verified that the air-to-ground mechanism involved in the present invention can reliably lock and release ammunition, and the release process is safe and reliable, with low disturbance, strong and simple structure, and easy to operate.

[0041] Example 2

[0042] This embodiment provides a small ammunition airdrop mechanism, which abandons the conventional pyrotechnic or ejection-actuated throwing form, and realizes the gravity delivery of ammunition through a single servo driving double connecting rod mechanism. The airdrop mechanism is mainly composed of a bottom plate, a ring seat, a ring, a rotating shaft, a latch, a latch support, a connecting rod, a servo, a rocker arm, and an adapter block.

[0043] The bottom plate (1) is the main body for connecting the mechanism and bearing the load, and is formed by winding a Kevlar fiber composite material. The material has high specific strength and light weight, and the bottom plate (1) and the flight platform are reliably fixed by bolts.

[0044] The holding ring adopts a two-ear design and is made of aluminum alloy together with the adapter block. The adapter block contacts the outer wall of the ammunition and is fixed in the corresponding position of the ammunition. It is connected to the holding ring seat through the shaft hole. A limiting hole is designed on the holding ring. The positioning and coordination between the pin and the holding ring and the limiting hole of the holding ring seat can achieve the purpose of limiting and restraining the holding ring, so that the holding ring can provide sufficient fastening force to the ammunition when it bears the gravity of the ammunition.

[0045] The servo is installed through the training mechanism connecting rod. When the servo rotates after receiving the control signal, the rocker arm drives the connecting rod to move inward along the axis of the ammunition, driving the pin to be pulled out from the limit hole of the holding ring, releasing the limit of the holding ring, and the ammunition falls under the action of gravity.

[0046] In summary, the present invention belongs to the technical field of weapon systems, and specifically relates to a small ammunition airdrop mechanism, which is mainly used for the aerial delivery of small ammunition. It has a compact structure, light weight, and convenient operation. It can adapt to a variety of unmanned aerial vehicle platforms. The delivery process is fast and stable, and the aerial delivery of small ammunition is realized. The airdrop mechanism includes a base plate, a ring seat, a ring, a rotating shaft, a latch, a latch support, a connecting rod, a steering gear, a rocker arm, and an adapter block. In the airdrop state, the ammunition is clamped and fixed by the ring. As an aerial delivery system for ammunition, the airdrop mechanism is fixed to the flight platform through the base plate. After receiving the control signal, the steering gear rotates and drives the connecting rod to move, thereby releasing the movable limit of the ring, and the ammunition falls freely under the action of gravity. In this way, the airdrop process of the ammunition is completed. The outstanding advantages of the present invention are: solving the difficulties of conventional airdrop mechanisms such as heavy weight and inconvenient operation. The solution has the characteristics of high strength, compact structure, small size, light weight, and easy operation. It can respond quickly after receiving the control signal, and the release activity of the holding ring is synchronized and reliable. It can adapt to different flight platforms such as unmanned / manned aircraft, rotary-wing / fixed-wing aircraft, and has a large space for promotion and application.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
