[0030] 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.

[0031] like Figure 1-2 As shown, a high-stability remote automatic grenade throwing device is provided. This throwing mechanism is suitable for grenades with a pull-out safety or similar throwing objects. It is used for remote intelligent release and throwing of a pull-ring projectile body 2. This throwing device is a single-module throwing mechanism, and the quantity and arrangement can be designed according to customer needs. It includes a frame 1, and the frame 1 is used to connect the remaining modules to form a multi-module throwing mechanism. The frame 1 is also installed with a drone to realize the release function and the throwing function during the flight.

[0032] The frame is provided with a pull ring fixing body 4, a rotation driving device, a push rod device and a flip bomb compartment 17. The technical means and technical effects of the modules are described in detail below:

[0033] 1. Pull ring fixing body

[0034] The pull ring fixing body 4 is provided with a pull ring groove 5 for the elastic body pull ring 3 to be inserted, and the center of the pull ring groove 5 is preferably coaxial with the rotation center of the pull ring fixing body 4. A lock buckle for locking the pull ring is provided in the pull ring groove 5, and the lock buckle specifically includes a lock tongue 6 and a lock tongue spring 7. The lock tongue 6 is rotatably connected to the pull ring fixing body 4, and one end of the lock tongue 6 is a tongue, and the tongue is connected to the lock tongue spring 7. The lock tongue spring 7 is used to push up the tongue of the lock tongue 6. When the elastic body pull ring 3 passes through the tongue, the tongue is first pushed open by the elastic body pull ring 3, and then the tongue is pushed up due to the restoring force of the lock tongue spring 7 and restored to the initial position. At this time, the elastic body pull ring 3 is located on the other side of the tongue and is locked by the tongue. The other end of the lock tongue 6 is provided with a dial head, which is exposed to the outside and is used for manual dialing. After the lock tongue 6 rotates, the tongue is opened, and the elastic body pull ring 3 can be withdrawn at this time.

[0035] The pull ring groove 5 is surrounded by a circular multi-segment inclined surface 8 on one side facing the grenade body 2. The circular multi-segment inclined surface 8 surrounds the outer periphery of the pull ring groove 5, so that the circular multi-segment inclined surface 8 is in contact with the push rod device during the rotation of the pull ring fixing body 4. The circular multi-segment inclined surface 8 is composed of a plane 9 and an upper inclined surface 10. The arc proportions of each part of the circular multi-segment inclined surface 8 are designed according to the timing of rotating the body pull ring 3 to release the safety and the body 2 being thrown. Since the throwing steps of the grenade are to rotate the body pull ring 3 to release the safety first and then throw it, the order of each surface is plane 9, upper inclined surface 10, and the initial contact position of the push rod device is plane 9. In order to make the circular multi-segment inclined surface 8 and the push rod device more stable, an arc surface or multiple inclined surfaces can be set between the plane 9 and the upper inclined surface 10. Alternatively, the lower slope may be arranged in the order of plane 9, upper slope 10, lower slope, plane 9. A plane 9 or an arcuate transition may be arranged between the upper slope 10 and the lower slope, and an arcuate or multi-slope transition may be arranged between the plane 9 and the lower slope.

[0036] 2. Rotation drive device

[0037] like Figure 3 As shown, the rotation drive device controls the rotation of the pull ring fixing body 4. Specifically, the rotation drive device includes a steering gear 11, a steering gear connecting frame 12, a bearing 13, and a bearing frame 14. The bearing 13 is fixedly connected to the frame body 1 through the bearing frame 14, and the steering gear 11 is fixedly connected to the frame body 1 through the steering gear connecting frame 12. The steering gear connecting frame 12 is a disc-shaped structure, which is buckled on one side of the bearing frame 14, and plays a role of sealing and dust isolation, thereby improving the stability of power output.

[0038] 3. Push rod device

[0039] like Figure 4 As shown, the push rod device includes a first push rod 15 and a guide structure 16 for guiding the push rod to move toward the elastic body 2. One end of the first push rod 15 is pressed against the annular multi-stage inclined surface 8. When the pull ring fixing device rotates, the first push rod 15 pushes the elastic body 2 outward along the upper inclined surface 10, so that the elastic body 2 is separated from the elastic body pull ring 3. The guide structure 16 is fixedly connected to the frame body 1, and a guide hole for the first push rod 15 to pass through is provided on the guide structure 16. Both ends of the first push rod 15 are provided with limit blocks to prevent the first push rod 15 from being separated from the guide hole.

[0040] In order to better reset the first push rod 15, a reset spring is provided between the first push rod 15 and the guide structure 16, so that the first push rod 15 is in a tightened state in real time.

[0041] 4. Flip the bomb bay

[0042] The flip bomb bay 17 is rotatably connected to the frame, and the rotation direction of the flip bomb bay 17 is perpendicular to the rotation direction of the pull ring fixing body 4. When the missile body 2 is pushed by the push rod device and separated from the missile body pull ring 3, the flip bomb bay 17 will rotate along the pushing direction of the push rod device, and the hatch of the flip bomb bay 17 changes from upward to downward, so that the missile body 2 relies on its own gravity to separate from the flip bomb bay 17, and the bomb is dropped.

[0043] In order to facilitate manufacturing, the complex structure of the frame 1 is split into a plurality of assembleable parts, and a support seat 18 is provided between the flip bomb bay 17 and the frame 1, the support seat 18 is fixedly connected to the frame 1, and the support seat 18 is rotatably connected to the flip bomb bay 17. A first permanent magnet 19 is provided at the bottom of the support seat 18, and a second permanent magnet 20 is provided at the bottom of the flip bomb bay 17. When the flip bomb bay 17 and the support seat 18 are rotated and closed, the first permanent magnet 19 and the second permanent magnet 20 are in contact, so that the flip bomb bay 17 and the support seat 18 are adsorbed and locked when closed, and the flip bomb bay 17 is locked with the opening vertically downward to ensure the accuracy of bombing.

[0044] A second push rod 21 is provided on the support body 1 or the support seat 18 , and a through hole matching with the second push rod 21 is provided at the bottom of the flip bomb bay 17 . The second push rod 21 passes through the through hole during the rotation of the flip bomb bay 17 .

[0045] A micro switch 22 for observing the rotation of the flip bomb bay 17 is provided on one side of the flip bomb bay 17. When the flip bomb bay 17 rotates, the micro switch 22 sends a signal to the controller to remotely confirm the release of the missile body 2.

[0046] A limiting structure 23 for limiting the position of the flip bomb bay 17 is provided on the frame side of the flip bomb bay 17 . The limiting structure 23 is preferably an arc-shaped groove structure that matches the flip bomb bay 17 .

[0047] In specific implementation, the high-stability remote automatic grenade throwing device of the present technology is divided into four stages, including: installation of the grenade body 2, release of the safety, throwing of the grenade body 2, and reset of the mechanism.

[0048] Installation of the projectile 2: Initialize the throwing mechanism, manually rotate the flip bomb bay 17 to the initial position, and when the opening of the flip bomb bay 17 is at a position with an angle of about 45° to the horizontal, place the grenade in the flip bomb bay 17, and continue to rotate after the bottom of the grenade body 2 is tightly attached to the bottom of the flip bomb bay 17; in the subsequent rotation process, insert the projectile pull ring 3 into the pull ring groove 5 of the pull ring fixing body 4, and when the projectile pull ring 3 is inserted into the pull ring groove 5 and contacts the tongue, push it with a little force, and the projectile pull ring 3 will be put on the tongue. At this time, the cylindrical surface on the top of the projectile 2 is tightly attached to the top tightening surface of the first push rod 15, so that the projectile 2 and the projectile pull ring 3 are locked and fixed.

[0049] Safety release: The steering engine 11 is started, the pull ring fixing body 4 drives the projectile pull ring 3 to start rotating, and the projectile pull ring 3 drives the grenade safety pin to rotate accordingly. When the projectile pull ring 3 rotates to a certain angle, the hook of the grenade safety pin will be separated from the grenade grip, and the grenade safety is released. At the same time, during the rotation of the pull ring fixing body 4, the annular multi-segment inclined surface 8 contacted by the first push rod 15 enters the upper inclined surface 10 from the plane 9, and the first push rod 15 is gradually pushed toward the projectile 2 by the upper inclined surface 10. The first push rod 15 pushes the upper end of the projectile 2, so that the projectile 2 gradually separates from the projectile pull ring 3 while rotating with the flip bomb compartment 17, and finally completely separates from the projectile pull ring 3, realizing automatic safety release.

[0050] Throwing of the missile body 2: After the security is completely released, the flipping bomb bay 17 continues to rotate according to gravity and inertia, and turns 180 degrees, so that the opening of the flipping bomb bay 17 is in a vertical downward state. At this time, the bottom surface of the flipping bomb bay 17 is connected to the bottom of the frame 1 or the support seat 18, and is adsorbed by magnetic force. When the two magnets are rotated to be tightly attached, the second push rod 21 passes through the through hole at the bottom of the flipping bomb bay 17, and the missile body 2 is pushed out of the flipping bomb bay 17, so that the missile body 2 is automatically thrown downward vertically.

[0051] Mechanism reset: When the micro switch 22 detects that the flip bomb bay 17 rotates, the servo 11 rotates in the opposite direction or continues to rotate, causing the pull rod fixing body to rotate in the opposite direction or continue to rotate, causing the first push rod 15 to enter the lower inclined surface area and eventually return to the initial plane 9 position. The first push rod 15 also gradually resets under the action of the spring force, thereby completing the reset of the entire drive mechanism.

[0052] 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.
