Description

Technical Field

[0001] The present invention relates to the technical field of intelligent throwing, and in particular to a fully automatic multi-bullet throwing device. Background Art

[0002] With the development of multi-rotor UAV technology, multi-rotor UAVs have become more and more mature flight platforms, so the technology of UAV-mounted mortar ejectors has significant advantages in battlefield applications. Existing UAV-mounted remote ejection technologies can only mount small ejection objects, and there is no ejection structure for large projectiles such as mortar shells, let alone multi-projectile ejection technology. Summary of the invention

[0003] The embodiment of the present invention provides a fully automatic multi-projectile throwing device, so as to provide a throwing device capable of targeting large projectiles and realizing the throwing of multiple projectiles.

[0004] In order to achieve the above purpose, the embodiment of the present invention provides the following technical solutions:

[0005] A fully automatic multi-bullet throwing device comprises a frame, on which is provided a mounting device for mounting a projectile, a locking hook device for controlling the mounting device to be separated from the projectile, and a control device for controlling the start-up of the locking hook device; the mounting device is rotatably connected to the frame, one end of the mounting device is provided with a first locking hook that matches the locking hook device, and the other end of the mounting device is provided with a hanging plate for mounting the projectile; the middle part of the locking hook device is rotatably connected to the frame, one end of the locking hook device is provided with a second locking hook that matches the first locking hook, and the other end of the locking hook device is provided with a trigger head; the control device comprises a first servo, the first servo controls a first shifting block to perform a rotational motion, and when the first shifting block contacts the trigger head during the rotation process, the locking hook device is rotated and the second locking hook is separated from the first locking hook, and the mounting device is separated from the projectile.

[0006] Furthermore, the mounting device includes a linkage plate, one end of which is rotatably connected to the frame, the other end of which is provided with a first locking hook, and a hanging plate is provided at the bottom of the rotating side of the linkage plate.

[0007] Furthermore, the hanging plate is an L-shaped plate.

[0008] Furthermore, a rotating structure is provided on the side of the trigger head that contacts the first shift block.

[0009] Furthermore, a spring sensor is provided on one side of the trigger head of the locking hook device and on the side located in the rotation direction of the trigger head, and a sensor trigger head matching the spring sensor is provided on the frame.

[0010] Furthermore, the shifting end of the first shifting block is provided with an inclined surface or an arc surface.

[0011] Furthermore, a second steering gear is provided on the frame, and the second steering gear controls the second shift block to perform rotational movement. When the second shift block rotates and contacts the second locking hook, the second shift block locks the locking hook device.

[0012] Furthermore, a cartridge corresponding to the hanging device is provided at the bottom of the frame, a cartridge cover is provided at the bottom of the cartridge, one end of the cartridge cover is rotatably connected to the cartridge, and the other end of the cartridge cover is locked with the cartridge through a locking device.

[0013] Furthermore, a bump bead and a bump bead channel for the bump bead to move are provided in the bump bead locking mechanism, a bump bead spring for applying a pre-tightening force to the bump bead is provided in the bump bead channel, so that part of the structure of the bump bead is exposed through the bump bead channel, and an embedding groove for fitting with the bump bead is provided on the cylinder.

[0014] The embodiments of the present invention have the following advantages:

[0015] The first steering gear of the fully automatic multi-bullet throwing device of the present invention drives the first shift block to rotate and trigger the lock hook device to rotate, so that the second lock hook is separated from the first lock hook, and the locking and unbinding of the mounting device is realized, and the fixing of the hanging plate is released. By controlling the hanging plate to flip, the projectile body falls under the action of gravity, and the mounting or throwing of the projectile body is realized. In addition, because the first shift block performs a rotational motion, multiple trigger heads can be set on the rotation path of the first shift block, and a set of steering gears can be used to control the unlocking of multiple lock hook devices.

[0016] The fully automatic multi-bullet throwing device of the present invention is provided with a second steering gear, and the second steering gear controls the rotation of the second shift block. When the second shift block rotates to a specified angle, the second lock hook can be locked between the first lock hook and the second shift block, preventing the rotation movement of the lock hook device, thereby playing a safety role for the lock hook device. Since the second shift block performs rotational movement, the second lock hook can be arranged on the rotation path of the second shift block, and the number of the first shift block corresponds to the number of the second lock hooks, so that one safety structure can lock multiple lock hook devices at the same time.

[0025] 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.

[0026] like Figure 1-2As shown, a fully automatic multi-bomb throwing device includes a frame 1. At least one bomb throwing device can be set on the frame 1 of the present technology as needed. The frame 1 is used to connect various devices. The frame 1 is individually designed according to the connection method and space design of each device, so that a specific interactive relationship is formed between the various devices. In this embodiment, four bomb throwing devices are arranged on the frame 1, and each bomb throwing device includes a mounting device for mounting a bomb body, a locking hook device 5 for controlling the mounting device to be separated from the bomb body, and a control device for controlling the activation of the locking hook device 5.

[0027] The mounting device is rotatably connected to the frame 1, one end of the mounting device is provided with a first lock hook 2 that matches with the lock hook device 5, and the other end of the mounting device is provided with a hanging plate 3 for hanging the projectile. The angle between the first lock hook 2 and the hanging plate 3 is not limited to 180° in this technology, and any angle is acceptable. As long as the technical solution that can meet the requirement that the projectile is separated from the hanging plate 3 due to the rotation of the mounting device after the first lock hook 2 is unlocked falls within the meaning of this technical feature. The optimal technical solution is that the mounting device includes a linkage plate 4, one end of the linkage plate 4 is rotatably connected to the frame, the other end of the linkage plate 4 is provided with a first lock hook 2, and the bottom of the rotating side of the linkage plate 4 is provided with a hanging plate 3, and the linkage plate 4 is arranged horizontally. When the first lock hook 2 is unlocked, the linkage plate 4 rotates downward due to the gravity of the first lock hook 2. At this time, the force arm of the first lock hook 2 is the largest, and the rotation force of the linkage plate 4 is in the maximum state, and the rotation speed of the linkage plate 4 is the fastest, so that the hanging plate 3 can be separated from the projectile at the fastest speed. The hanging plate 3 is an L-shaped plate, one side of the hanging plate 3 is perpendicular to the linkage plate 4, and the other side of the hanging plate 3 is parallel to the linkage plate 4, so that the angles of the hanging plate 3 and the linkage plate 4 can be synchronized, which is convenient for disassembly, assembly and alignment.

[0028] The middle part of the locking hook device 5 is rotatably connected to the frame body 1, and one end of the locking hook device 5 is provided with a second locking hook 6 that cooperates with the first locking hook 2, and the other end of the locking hook device 5 is provided with a trigger head 7. When the trigger head 7 is pushed, the locking hook device 5 rotates along the pushing direction, and the second locking hook 6 will rotate in the opposite direction of the first locking hook 2, and finally the second locking hook 6 will be separated from the first locking hook 2.

[0029] A projectile sensor 8 is provided on one side of the trigger head 7 of the locking hook device 5 and on the side located in the rotation direction of the trigger head 7. The projectile sensor is used to feedback to the user whether there is a projectile in the cartridge. A sensor trigger head that cooperates with the projectile sensor 8 is provided on the frame.

[0030] The control device includes a first servo 9, which controls the first shift block 10 to rotate. When the first shift block 10 contacts the trigger head 7 during the rotation process, the lock hook device 5 rotates and the second lock hook 6 is separated from the first lock hook 2, and the mounting device is separated from the projectile. Since the first shift block 10 rotates, multiple trigger heads 7 can be set on the rotation path of the first shift block 10, so that one set of servos can control the unlocking of multiple lock hook devices 5. According to the existing process level, considering the weight of the entire device and the volume of the projectile, the best way is to evenly distribute 4 throwing devices.

[0031] Since the first shift block 10 hits the actuating head 7 during the rotation process, in order to ensure the linkage stability between the actuating head 7 and the first shift block 10 and to minimize the instantaneous friction between the two, a rotating structure such as a roller, a wheel, a bearing, etc. is provided on the side of the actuating head 7 that contacts the first shift block 10, and the actuating end of the first shift block 10 is provided with an inclined surface or an arc surface.

[0032] In order to prevent the lock hook device 5 from being unlocked due to turbulence during flight, a safety structure is added. In the present technology, the safety structure is that a second servo 11 is provided on the frame 1. The second servo 11 controls the second shift block 12 to rotate. When the second shift block 12 rotates and contacts the second lock hook 6, the second shift block 12 will support the second lock hook 6. The second lock hook 6 is clamped between the first lock hook 2 and the second shift block 12, so that the second shift block 12 locks the lock hook device 5. Since the second shift block 12 rotates, the second lock hook 6 can be set on the rotation path of the second shift block 12, and the number of the first shift block 10 corresponds to the number of the second lock hook 6, so that one safety structure can lock multiple lock hook devices 5 at the same time.

[0033] like Figure 3 As shown, a cartridge 13 corresponding to the hanging device is provided at the bottom of the frame 1, and a cartridge cover 14 is provided at the bottom of the cartridge 13. One end of the cartridge cover is rotatably connected to the cartridge 13, and the other end of the cartridge cover is locked with the cartridge 13 through a locking device. The locking device of the cartridge cover 14 in this embodiment is a ball locking device 15.

[0034] like Figure 4 As shown, a ball locking mechanism is provided with a ball 16 and a ball channel 17 for the ball to move, and a ball spring 18 is provided in the ball channel 17 for applying a pre-tightening force to the ball 16, so that part of the structure of the ball 16 is exposed from the ball channel 17, and a groove 19 for fitting with the ball is provided on the cylinder 13.

[0035] The working process of the throwing device described in this embodiment is as follows:

[0036] Loading: First open the barrel cover 14, put the mortar bullet head downward into the barrel 13, and push the tail of the bullet body upward in the barrel 13. During the rising process, the tail of the bullet body will contact the hanging plate 3, and then drive the hanging device to flip until the first locking hook 2 is mounted on the second locking hook 6. The installation and locking of the bullet body can be completed, and the bullet body is reliably mounted. After all the bullet bodies are installed, close all the barrel covers 14.

[0037] Safety locking: After the missile body is installed, the second steering gear 11 is started to rotate the second shift block 12 to a specified angle to support the second lock hook 6, thereby completing the safety locking. At this time, the missile body will not be accidentally released due to misoperation, etc., thereby ensuring the safety of personnel and avoiding harmful effects.

[0038] Safety release: During the flight, if the projectile needs to be thrown, the second steering gear 11 is started, and the second shifting block 12 rotates to disengage from the second locking hook 6, so that the safety can be released.

[0039] Projectile casting: After the safety is released, the first servo 9 is started, the first shift block 10 rotates, and the first shift block 10 squeezes the trigger head 7 on the rotation path, pushing the trigger head 7 to move outward, and the lock hook device 5 rotates, driving the second lock hook 6 to disengage from the first lock hook 2, thereby releasing the fixation of the mounting device. At this time, the hanging plate 3 is flipped under the gravity of the projectile, and finally the projectile is separated from the hanging plate 3 and presses down the cylinder cover 14, and the bumping ball squeezes the bumping ball spring to move into the bumping ball channel, and the bumping ball is separated from the embedded groove. The cylinder cover flips down and opens due to its own gravity, and the projectile falls, and the casting is completed.

[0040] 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.
