[0026] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1As shown, a high-stability automatic throwing device for unmanned aerial vehicles with integrated release and throwing functions is provided. This throwing mechanism is suitable for explosion-proof bombs in the form of direct-pull safety or similar types of throwing objects. It is used for the remote intelligent release of riot-proof bombs, grenades and other projectiles with pull rings on unmanned aerial vehicles. The projectile body 1 includes a frame 2, and the frame 2 is used to fix the various components in the present technology, and the frame 2 is also provided with a connecting structure fixed to the aircraft.

[0028] The frame 2 is provided with an anti-riot bomb bay 3 and a support plate 4 for fixing the projectile 1. When the projectile 1 is fixed, the anti-riot bomb bay 3 and the support plate 4 are respectively fixed on both sides of the projectile 1. In this embodiment, the anti-riot bomb bay 3 and the support plate 4 are distributed up and down, and the anti-riot bomb bay 3 is a semi-open warehouse structure, with the opening downward and toward the support plate 4. In order to make the projectile 1 more firmly fixed, an elastic body can be set on the anti-riot bomb bay 3 or the support plate 4 to provide elastic support for the projectile 1 to avoid the projectile 1 falling off or exploding due to turbulence during flight.

[0029] The frame 2 is provided with a light sensor 5 for detecting the light blocking condition of the projectile 1. Specifically, a positioning hole is provided on the frame 2 between the anti-riot bomb bay 3 and the support plate 4, and the light sensor 5 passes through the positioning hole and is locked by a self-provided nut to achieve its fixation on the frame 2. This technology utilizes the light sensing function of the light sensor 5 component to detect the light blocking condition of the projectile 1 between the anti-riot bomb bay 3 and the support plate 4, and then determines whether there is a projectile 1 and whether the casting is successful; on the contrary, when there is a projectile, light cannot penetrate the projectile to irradiate the light sensor.

[0030] The anti-riot bomb bay 3 is rotatably connected to the frame 2, and the frame 2 is provided with a magnetic device 6 for preventing the anti-riot bomb bay 3 from rotating. The magnetic device 6 includes a first magnet and a second magnet, the first magnet is fixed on the frame 2, and the second magnet is fixed on the anti-riot bomb bay 3. The first magnet and the second magnet are arranged oppositely between the frame 2 and the anti-riot bomb bay 3, and the two magnets attract each other to achieve adsorption and locking of the anti-riot bomb bay 3 and the frame 2.

[0031] like Figure 2 As shown, the frame 2 is also provided with a slider 7 for controlling the translation of the support plate 4. Regardless of whether the slider 7 is located on the upper, lower, left, or right side of the support plate 4, as long as the slider 7 can drive the support plate 4 to move in the same direction, the technical solution falls within the protection scope of the present invention. Specifically, a matching protrusion 8 and groove 9 are provided between the slider 7 and the support plate 4. The present technology does not limit the specific positions of the protrusion 8 and the groove 9. As long as the slider 7 and the support plate 4 achieve synchronous movement through the concave-convex matching structure, it falls within the meaning of the technical features of the present invention.

[0032] The frame 2 is provided with a driving device for controlling the movement of the slider 7. Specifically, the driving device includes a servo 10, a driving gear 11 and a bar gear 12. Both sides of the servo 10 are fixed to the frame 2, or an auxiliary frame 2 can be added to fix the servo 10. The servo 10 drives the rotation stroke and rotation direction of the driving gear 11. The bar gear 12 is arranged on the slider 7. The driving gear 11 rotates to drive the bar gear 12 to move, so that the servo 10 controls the movement of the slider 7. The present technology is not limited to the combination of gears and racks, but also includes a screw structure. As long as the servo 10 drives the translation, it falls within the protection scope of the present technology.

[0033] The rotation center of the driving gear 11 is provided with an outward annular protrusion, and the outer side of the annular protrusion is sleeved with a bearing 13, which is fixed on the frame 2 and is used to balance the force on the driving gear 11, so that the rotation of the driving gear 11 is more stable, and at the same time, the force on the rotating shaft of the steering gear 10 is relieved, so that the operation of the steering gear 10 is more stable.

[0034] like Figure 3 As shown, the frame 2 is provided with a mother-and-child pin assembly 14, a first through hole 15 matched with the mother-and-child pin assembly 14, and a cavity structure 16 for the mother-and-child pin assembly 14 to move. The slider 7 is provided with an inclined surface 17 matched with the mother pin. The cavity structure 16 is provided with a second through hole 18 matched with the mother-and-child pin assembly 14 on the side facing the inclined surface 17. Pins are provided on both sides of the mother-and-child pin assembly 14, and the two pins are respectively matched with the first through hole 15 and the second through hole 18. When the slider 7 is in the translation process, one of the pins of the mother-and-child pin assembly 14 passes through the second through hole 18 and contacts the inclined surface 17. As the inclined surface 17 changes, the mother-and-child pin assembly 14 moves perpendicular to the translation direction of the slider 7 until the mother-and-child pin assembly 14 passes through the first through hole 15 or is separated from the first through hole 15.

[0035] The parent-child pin assembly 14 includes a large pin 19 and a small pin 20. One end of the large pin 19 is provided with a pin cavity for accommodating a partial structure of the small pin 20. A first spring 21 surrounding the partial structure of the small pin 20 is provided in the pin cavity. The small pin 20 is provided with a first annular protrusion 27 that presses against the first spring 21. The spring is between the first annular protrusion 27 and the wall of the pin cavity, so that there is an elastic restoring force between the large pin 19 and the small pin 20. The first spring 21 is used to reset the pin located above. In this embodiment, the small pin 20 is located above the large pin 19, and the first spring 21 is used to reset the small pin 20. On the contrary, if the large pin 19 is located above the small pin 20, the first spring 21 resets the large pin 19. It should be emphasized that the present technology also includes a technical solution in which the large pin 19 is on top and the small pin 20 is on the bottom. In order to ensure the stability of the parent-child pin assembly 14, a second spring 22 for resetting the large pin 19 and a second annular protrusion 28 for compressing the second spring 22 are provided on the outer side of the large pin shaft 19, so that elastic contact is formed between the large pin shaft 19 and the small pin shaft 20, and between the large pin shaft 19 and the cavity structure 16, thereby ensuring the stability of the parent-child pin assembly 14 as a safety function.

[0036] like Figure 4 As shown, a lock pin 23 for hanging the elastic body pull ring 26 is provided on one side of the slider 7 located on the support plate 4. A lever 24 is provided on the lock pin 23, and a third spring 25 is provided on the support plate 4 along the moving direction of the support plate 4. A cavity for accommodating the third spring 25 is provided on the support plate 4, and the lever 24 is inserted into the cavity and connected to the third spring 25. The third spring 25 presses against the lever 24 and is located on one side of the elastic body pull ring 26. When the slider 7 drives the lock pin 23 to translate and pull the pull ring outward, the third spring 25 can delay the timing of pulling the pull ring. After the slider 7 moves a certain distance, when the force pulling the pull ring is less than the elastic force of the third spring 25, the lock pin 23 is supported by the restoring force of the third spring 25 to accelerate the pulling of the pull ring, which increases the time for the subsequent steps, thereby increasing safety.

[0037] The specific working steps of this technology are divided into four stages, namely: installation of the projectile 1, release of the safety of the projectile 1, throwing of the projectile 1, and resetting of the transmission mechanism.

[0038] Installation of the projectile 1: The projectile 1 is placed upside down in the anti-riot bomb bay 3, and the anti-riot bomb bay 3 is rotated so that the anti-riot bomb bay 3 is adsorbed and locked on the frame 2, and the lower end surface of the projectile 1 is clamped on the column support plate 4 to ensure that the projectile 1 and the support plate 4 are tightly attached without gap. Then the safety pull ring of the projectile 1 is sleeved on the locking pin 23 of the slider 7. The locking pin 23 is provided with an arc-shaped step, and the safety pull ring can be embedded in the arc-shaped step to avoid the problem of falling off due to turbulence during flight. Under this working condition, the projectile 1 and the safety pull ring are installed and fixed.

[0039] Safety release and passive casting of projectile 1: The servo 10 rotates to drive the slider 7 to move backward, and the safety pull ring of the projectile 1 moves backward with the slider 7. The length of the groove 9 can be designed according to needs to determine the timing of driving the support plate 4 to move horizontally during the movement of the slider 7. This timing can be any time point during the movement of the slider 7. When the slider 7 starts to move backward, the support plate 4 is restricted and in a static state. At the same time, the projectile 1 and the support plate 4 are also in a static state after being pressed against each other. During the movement of the slider 7, the protrusion 8 between the slider 7 and the support plate 4 supports the groove 9 wall, so that the support plate 4 moves synchronously with the slider 7.

[0040] During the movement of the slider 7, the parent-child pin assembly 14 moves downward due to the change of the inclined surface 17 until the pin shaft is retracted from the first through hole 15, the steering gear 10 stops, and the slider 7 stops moving. At this time, the safety pull ring of the projectile 1 is completely separated from the projectile 1 as the slider 7 moves, completing the release of the safety of the projectile 1. At the same time, the support plate 4 is completely retracted, the support plate 4 is separated from the projectile 1, and the projectile 1 realizes free fall and is thrown downward, completing the throwing of the projectile 1.

[0041] On the contrary, the steering gear 10 controls the slider 7 to move in the opposite direction, and the inclined surface 17 gradually becomes thicker, driving the pin shaft of the parent-child pin assembly 14 to pass through the first through hole 15. The parent-child pin assembly 14 can limit the translation distance of the slider 7 to prevent the slider 7 from excessive movement.

[0042] Transmission mechanism reset: After the projectile 1 is thrown, the servo 10 starts to rotate in the opposite direction, and the slider 7 starts to slide in the opposite direction. The parent-child pin assembly 14 cooperates with the inclined surface 17 to gradually move upward. At the same time, the small pin shaft 20 moves upward under the action of the joint elastic force of the first spring 21 and the second spring 22. The small pin shaft 20 passes through the first through hole 15. At this time, the servo 10 stops rotating, the support plate 4 and the slider 7 are completely in the initial position, and the transmission mechanism is reset.

[0043] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
