Technical Field

[0001] This invention relates to the field of aircraft launch systems, and more particularly to a small-space airborne suspended launch mechanism. Background Technology

[0002] In the military field, advancements in modern air combat and aircraft performance have transformed modern warfare, making air superiority the primary objective for fighter jets. Airborne weapon launchers are crucial components for launching various missiles from fighter jets. As weapon sizes increase, the demands on launch mechanisms also rise, requiring lightweighting and miniaturization. Meanwhile, in the civilian sector, drones are playing an increasingly important role, with growing demand for their use in delivering various supplies.

[0015] In one technical solution of the present invention, the connecting rod is provided with a first hinge hole, which is disposed through the side of the connecting rod;

[0016] The rear end of the rocker arm is provided with a second hinge hole, which extends through the side of the rocker arm.

[0017] A hinge shaft is provided on the outer side of the movable slide rail. The hinge shaft is disposed in the first hinge hole and the second hinge hole and is fixed by a limiting fastener. A bearing is provided between the hinge shaft and the second hinge hole.

[0018] In one embodiment of the present invention, the movable slide rail includes:

[0019] The upper movable slide rail limiting block has a hinge shaft disposed on its outer side surface; the inner side surface of the upper movable slide rail limiting block is provided with a protruding upper limit protrusion, the bottom surface of which is horizontally disposed; the front end of which is provided with a front limiting protrusion.

[0020] The lower sliding rail limiting block has a lower limiting protrusion on its side. The top surface of the lower limiting protrusion is inclined and forms a second sliding groove with the upper limiting protrusion. The upper end of the lower sliding rail limiting block is hinged to the lower end of the upper sliding rail limiting block.

[0021] In one technical solution of the present invention, the upper end of the lower movable slide rail limiting block and the lower end of the upper movable slide rail limiting block are hinged by a hinge structure, the hinge structure comprising:

[0022] An upper hinge limiting block is spaced apart at the lower end of the upper movable slide rail limiting block; a hinge limiting groove is formed between two adjacent hinge limiting blocks; a first shaft hole is provided on the upper hinge limiting block, which extends through its front and rear ends;

[0026] In one embodiment of the present invention, the suspended support includes a suspension beam and two sliders disposed on the top surface of the suspension beam. The width of the two sliders is greater than the width of the suspension beam, and the sides of the sliders are inserted into the first and second slide grooves.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] This invention proposes a small-space airborne suspended object launching mechanism. It comprises a fixed slide rail, a movable slide rail, a suspended object support, a folding mechanism, and a locking mechanism. A slider on the suspended object support slides along a first groove on the fixed slide rail and a second groove on the movable slider. The folding mechanism includes a rocker arm, with its two ends hinged to the fuselage and the movable slide rail, respectively. Upon unlocking via the locking mechanism, the slider on the suspended object support slides along the first and second grooves under gravity, causing the rocker arm to unfold. Once the suspended object reaches a safe separation distance from the fuselage, the suspended object support detaches from the movable slider, enabling the release of the suspended object and ensuring the safety of both the aircraft and the suspended object. This invention can be used to reduce the spatial size of airborne launch devices, lessen restrictions on the payload, and allow a single aircraft to carry larger missiles or civilian supplies.

[0029] This invention has a simple structure and is easy to implement. The fixed slide rail, the moving slide rail and the suspended object bracket are locked by a locking mechanism to achieve fixed mounting of the suspended object. The locking mechanism is unlocked and the suspended object is released by unfolding the rocker arm. The rocker arm can be folded and set under the carrier, thereby reducing the space occupied by the small space airborne suspended object launching mechanism and making it easy to adapt to different carrier models.

[0030] In this invention, the suspension mechanism also includes a connecting rod, and the rocker arms can be several sets arranged along the connecting rod. By adjusting the length of the rocker arms on the connecting rod, the launch attitude angle when the suspended object separates can be adjusted, thereby enabling the suspended object to separate from the carrier aircraft at a specific attitude angle, which improves the flexibility and safety of the suspended object launch method.

[0031] In this invention, the locking mechanism includes an unlocking drive mechanism and a limit stop. The locking and unlocking methods of the suspended object bracket are simple and easy to operate, which improves the deployment efficiency of the airborne suspended object launching mechanism in a small space.

[0032] Based on function and operating conditions, this invention decomposes the slide rail structure in the fixed mounting state and the launch and release state into two different parts, each realizing its own function, simplifying the integration complexity; and through multiple sets of linkage structures, the separation launch attitude angle can be specified in advance, ensuring the reliability of separation launch and the safety of both the suspended object and the carrier aircraft.

[0051] The description of the embodiments in this specification should be taken in conjunction with the accompanying drawings, which should form part of the complete specification. In the drawings, the shape or thickness of the embodiments may be exaggerated and may be indicated in a simplified or convenient manner. Furthermore, parts of the various structures in the drawings will be described separately; it is worth noting that elements not shown in the figures or not described in words are in a form known to those skilled in the art.

[0052] The descriptions of the embodiments herein, including any references to directions and orientations, are for ease of description only and should not be construed as limiting the scope of the invention. The following description of preferred embodiments involves combinations of features, which may exist independently or in combination; the invention is not particularly limited to the preferred embodiments. The scope of the invention is defined by the claims.

[0053] like Figures 1 to 8 As shown, a small-space airborne suspended object launching mechanism of the present invention includes a fixed slide rail 1, a suspended object support 2, a folding mechanism, a movable slide rail 4 and a fixed slide rail 1, and a locking mechanism.

[0054] The upper end of the fixed slide rail 1 is fixed to the machine body, and a first slide groove 11 is provided on its side;

[0055] The hanging bracket 2 is set at the front end of the fixed slide rail 1. The hanging bracket 2 is provided with a slider 22, which is adapted to the first slide groove 11. The hanging bracket 2 is set in the first slide groove 11 through the slider 22 and connected to the fixed slide rail 1.

[0056] The folding mechanism includes a rocker arm 3, which is located on the front side of the suspension bracket 2 and its front end is hinged to the body.

[0057] The movable slide rail 4 is located at the front end of the suspended support 2, and its side is hinged to the rear end of the rocker arm 3. The movable slide rail 4 is provided with a second slide groove 41 that is adapted to the slider 22. The bottom surface of the slider 22, the top surface of the first slide groove 11, and the top surface of the second slide groove 41 are inclined downward from the rear to the front.

[0058] The locking mechanism is located at the front end of the suspension bracket 2 and is used to restrict the slider 22 from sliding forward along the first slide groove 11 and the second slide groove 41.

[0059] Because the bottom surface of the slider 22, the top surface of the first slide groove 11, and the top surface of the second slide groove 41 are inclined downwards from back to front, the slider 22 of the suspended object bracket 2 can slide forward along the first slide groove 11 into the second slide groove 41 after the locking mechanism is unlocked. Simultaneously, the rear end of the rocker arm 3 is connected to the side of the moving slide rail 4. Under the action of gravity, the suspended object bracket 2 and the moving slide rail 4 drive the rocker arm 3 to rotate away from the fuselage. The suspended object is released when the rocker arm 3 rotates to a safe distance from the fuselage, ensuring the safety of the suspended object and the carrier aircraft. When the suspended object bracket 2 is fixed to the carrier aircraft via the fixed slide rail 1, the rocker arm 3 is in a folded state, effectively reducing the installation space occupied by the suspended object launching mechanism and making it widely applicable to various carrier aircraft models.

[0060] According to one technical solution of the present invention, the locking mechanism includes an unlocking drive mechanism 6 and a limiting block 7. The top surface of the unlocking drive mechanism 6 is fixed to the body, and its front end is provided with an unlocking drive linkage 61; the limiting block 7 is connected to the unlocking drive linkage 61 and moves back and forth with the unlocking drive linkage 61; the rear end of the limiting block 7 is provided with a protruding front limiting block 71, which abuts against the front end surface of the hanging bracket 2.

[0061] The unlocking drive mechanism 6 is a pyrotechnic device or an electric device that can move mechanically under the energy or electrical energy generated by an explosion, pushing the unlocking drive linkage 61 to move forward, thereby driving the limit block 7 to move forward, so that the front limit block 71 is disengaged from the suspension bracket 2, making it convenient for the suspension bracket 2 to slide on the fixed slide rail 1 and the moving slide rail 2.

[0062] According to one technical solution of the present invention, the rocker arm 3 includes a plurality of rocker arms 3 arranged sequentially front to back, and the folding mechanism further includes a connecting rod 5. The plurality of rocker arms 3 are arranged along the length direction of the connecting rod 5 and are hinged to the connecting rod 5. The connecting rod 5 is provided with a rear rocker arm storage groove 51 for accommodating the rocker arm 3 arranged on the connecting rod 5 in the folded state.

[0063] By adjusting the length of the rocker arm 3 connected to the connecting rod 5, the launch attitude angle during the separation of the suspended object can be adjusted, thereby enabling the suspended object to separate from the carrier aircraft at a specific attitude angle, thus improving the flexibility of the suspended object launch method.

[0064] According to one technical solution of the present invention, the connecting rod 5 is provided with a first hinge hole 52, which is disposed through the side of the connecting rod 5; the rear end of the rocker arm 3 is provided with a second hinge hole 31, which is disposed through the side of the rocker arm 3; a hinge shaft 43 is provided on the outer surface of the movable slide rail 4, which is disposed in the first hinge hole 52 and the second hinge hole 31 and fixed by a limiting fastener; a bearing is provided between the hinge shaft 43 and the second hinge hole 31, which further improves the flexibility of the movable slide rail 4, the rocker arm 3 and the connecting rod 5 in rotation.

[0065] According to one technical solution of the present invention, the movable slide rail 4 includes an upper movable slide rail limiting block 42 and a lower movable slide rail limiting block 44. A hinge shaft 43 is disposed on the outer side of the upper movable slide rail limiting block 42; an upper limit protrusion is provided on the inner side of the upper movable slide rail limiting block 42, and the bottom surface of the upper limit protrusion is horizontally disposed; a front limit protrusion is provided at the front end of the upper limit protrusion; a lower limit protrusion is provided on the side of the lower movable slide rail limiting block 44, and the top surface of the lower limit protrusion is inclinedly disposed, forming a second sliding groove 41 with the upper limit protrusion; the upper end of the lower movable slide rail limiting block 44 is hinged to the lower end of the upper movable slide rail limiting block 42.

[0066] According to one technical solution of the present invention, the upper end of the lower moving slide rail limiting block 44 and the lower end of the upper moving slide rail limiting block 42 are hinged by a hinge structure, the hinge structure comprising:

[0067] The upper hinge limiting block is spaced apart at the lower end of the upper sliding rail limiting block 42; a hinge limiting groove is formed between two adjacent hinge limiting blocks; the upper hinge limiting block is provided with a first shaft hole that passes through its front and rear ends;

[0068] The lower hinge limiting block is spaced at the lower end of the lower sliding rail limiting block 44, and its width is adapted to the width of the hinge limiting groove; the lower hinge limiting block is provided with a second shaft hole that passes through its front and rear ends, and the first shaft hole and the second shaft hole are collinear.

[0069] The connecting shaft is located within the first shaft hole and the second shaft hole.

[0070] The hinge structure, along with the upper limit protrusion and the front limit protrusion, constitutes the suspension unlocking mechanism. The upper limit protrusion on the upper sliding rail limit block 42 guides the slider 22 smoothly into the second slide groove 41. The front limit protrusion limits the front end of the slider 22 as it slides into the second slide groove 41, preventing the slider from disengaging from the second slide groove before the rocker arm 3 is fully extended, thus preventing premature separation of the suspended object and affecting its launch angle. When the rocker arm 3 is fully extended, the upper sliding rail limit block 42 and the lower sliding rail limit block 44 are hinged together. Under gravity, the lower sliding rail limit block 44 rotates downwards, and the front limit protrusion loses its limiting effect on the slider 22. The slider 22 continues to slide forward, separating the suspension bracket 2 from the sliding rail 4, thus launching the suspended object.

[0071] According to one technical solution of the present invention, the fixed slide rail 1 includes two slide rail blocks arranged opposite to each other and a fixed slide rail crossbeam connecting the two slide rail blocks. The upper ends of the two slide rail blocks are provided with bolt holes for fixing to the machine body. The lower ends of the two slide rail blocks are provided with a first slide groove 11. The first slide groove 11 is provided on the opposite end faces of the two slide rail blocks. The rear end of the first slide groove 11 is provided with a rear limiting part.

[0072] According to one technical solution of the present invention, the suspension bracket 2 includes a suspension beam 21 and two sliders 22 disposed on the top surface of the suspension beam 21. The width of the two sliders 22 is greater than the width of the suspension beam 21. The sides of the sliders 22 are inserted into the first slide groove 11 and the second slide groove 41 to improve the flexibility of the sliders 22 sliding in the first slide groove 11 and the second slide groove 41.

[0073] The working process of this invention is as follows:

[0074] During normal flight with the load attached, the suspended object is fixed to the suspension support 2 and locked by the unlocking drive mechanism 6, thus achieving fixation with the fixed slide rail 1 and the moving slide rail 4, enabling a reliable connection with the carrier aircraft.

[0075] When the launch and separation are initiated, the unlocking drive mechanism 6 is unlocked, and the slider 22 of the suspension bracket 2 slides into the first groove 11 on the fixed slide rail 1 and the second groove 41 on the moving slide rail 4.

[0076] The movable slide rail 4 and the rocker arm 3 are connected by a bearing, allowing the movable slide rail 4 and the rocker arm 3 to rotate around the fixed end of the rocker arm 3, thus moving the suspended object away from the carrier.

[0077] Depending on the size of the suspended object, there can be multiple combinations of fixed slide rail 1, movable slide rail 4, and rocker arm 3. Each combination is interconnected by connecting rods 5, and the connection between the connecting rods 5 can be pre-set to a specific attitude angle. Under the constraint of the connecting rods 5, the movable slide rail 4 moves away from the carrier at a specific attitude angle, thus separating the suspended object from the carrier.

[0078] Once the distance between the suspended object and the carrier aircraft reaches a safe separation distance, the suspension unlocking mechanism of the moving slide rail 4 unlocks and releases the suspended object. The suspended object can then separate from the carrier aircraft at a specific attitude angle, completing the launch of the airborne suspended object.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.

[0080] Finally, it should be noted that the above description represents a preferred embodiment of the present invention. It should be pointed out that although preferred embodiments have been described, those skilled in the art, once they understand the basic inventive concept of the present invention, can make various improvements and modifications without departing from the principles described herein.
