[0002] With the development of drone technology, the application of drones has extended to all walks of life, especially high-altitude firefighting and battlefields. Drones have the advantages of high flexibility, ease of use, low cost, and applicability to high-risk environments. Currently, most of the devices used are clamp-type missile installation devices. The mechanical arms that clamp the missiles are large in size and heavy in weight. The corresponding mechanical arm locking and releasing mechanisms are complex and have a large loading volume. However, the use of drones for bombing requires a high load capacity of the drone. The bombing device needs to be as light as possible and have a heavy load, so a lightweight bombing device is needed. Summary of the invention

[0021] The present invention provides a lightweight bomb pod solution, which realizes the bomb delivery by pushing the linear push rod to control the opening and closing of the hook and the block. When the hook and the block are opened, the compression spring can provide thrust to push the bomb out, so that the bomb and the pod are separated smoothly. At the same time, the tension spring pulls the linear push rod to prevent the linear push rod from suddenly extending due to inertia during flight, causing the hook and the block to separate, thus playing a protective role. The present invention has a compact and reliable structure, is easy to use, is light in weight, and has a low manufacturing cost.

[0022] In embodiment 1 of the present invention, Figure 1-8 As shown: A novel bomb pod includes a locking and releasing mechanism, wherein the locking and releasing mechanism includes an operating part and a driving part for driving the operating part to open and close, wherein the operating part includes:

[0023] An L-shaped hook 15, wherein the L-shaped hook 15 includes a mounting slope 151 at an end thereof;

[0024] H-shaped stopper 6, the H-shaped stopper 6 comprises an outer stopper long arm 61 and an inner stopper short arm 62;

[0025] Accommodation space 20 , the outer block long arm 61 , the inner block short arm 62 and the installation inclined surface 151 can enclose an accommodation space 20 that can accommodate the lifting ring 191 .

[0026] In this embodiment:

[0027] The embracing release device contacts the side of the projectile, and its multiple embracing clamping arms contact the lateral position of the projectile, which has a horizontal component force. Therefore, the clamping force required to be provided by the clamping arm is greater than the gravity of the projectile, and requires a larger volume or a larger output power structure support. After being held by F1 and F2, F1 and F2 exert a certain component force in the horizontal direction after being decomposed, which increases the additional output of the system.

[0028] In this embodiment, the locking and releasing mechanism plays the role of limiting the movement of the projectile 19 and releasing the projectile 19. The hook wrapped around the projectile 19 absorbs vibration when the projectile 19 vibrates in the horizontal direction, thereby protecting the projectile 19. The projectile 19 is fixedly connected to the lifting hook 191. When in use, the projectile 19 is suspended below the accommodation space 20 by the lifting hook 191; when the projectile is kept suspended, it is only subjected to a pulling force F pull from directly above the projectile and its own gravity G. Under this structure, a preload force can be applied to the projectile to assist in the release of the projectile to improve the release efficiency of the projectile. F pull is directly provided by the pod through the lifting ring, which greatly reduces the load requirement of the pod for early projectile mounting and release.

[0029] The H-shaped stopper serves to block the hook and limit the movement of the projectile 19. The bottom of the H-shaped stopper 6 is designed to be concave to form an H-shaped structure, which can form a receiving space 20 together with the mounting slope 151 to wrap the lifting hook 191 of the projectile 19, absorb vibration when the projectile 19 vibrates in the horizontal and vertical directions, and protect the hook 15 and other important parts.

[0030] The installation slope 151 provides a larger release angle when releasing the lifting hook 191, and utilizes the gravity of the projectile and the thrust provided by other mechanisms to provide a downward component force, thereby releasing the projectile faster.

[0031] The structure of the H-shaped stopper 6, the L-shaped hook 15 and the accommodating space is compact, the force point of the hoisting bomb is more accurate, and a certain buffer is provided by the H-shaped stopper 6, thereby improving the loading safety.

[0032] In Example 2 of the present invention, Figure 1-5 As shown, the difference from the above embodiment is that: the driving part includes: a connecting rod 7, a linear push rod 13, a first pin shaft 90, a second pin shaft 91, and a third pin shaft 92; the L-shaped hook 15 includes a vertical arm 152 and a horizontal arm 153 fixedly connected to the vertical arm 152;

[0033] The upper surface of the end of the cross arm 153 has a mounting slope 151;

[0034] The top of the vertical arm 152 with an opening is hinged to the connecting rod 7 through the first pin 90, and the middle of the vertical arm 152 with a through slot is hinged to the fixed part through the third pin 92; the third pin 92 is hinged to the protrusion of the support plate 2 in the fixed part;

[0035] The connecting rod 7 is connected to the linear push rod 13 through the second pin 91;

[0036] The linear push rod 13 drives the connecting rod 7 to move horizontally, and the connecting rod 7 drives the vertical arm 152 to rotate around the third pin shaft 92, thereby driving the horizontal arm 153 and the mounting inclined surface 151 to move.

[0037] In these embodiments:

[0038] The vertical arm 152 of the hook 15 is connected to the connecting rod through the first pin shaft 90, and the horizontal arm 153 of the hook 15 is connected to the fixing part through the third pin shaft 92 to fix the hook, so that when the connecting rod 7 moves horizontally to the left, the vertical arm 152 rotates counterclockwise around the third pin shaft 92, and the horizontal arm 153 and the mounting inclined surface 151 move counterclockwise away from the lifting ring 191. The third pin shaft 92 is hinged to the protrusion of the support plate 2 of the fixing part; it can quickly release the elastic body.

[0039] In Example 3 of the present invention, Figure 1-5 As shown, the difference from the above embodiment is that: the driving part further includes: a fourth pin shaft 93, a fifth pin shaft 94, and the H-shaped stopper 6 further includes a driving stopper arm 63 which is fixedly connected to the outer stopper long arm 61 and the inner stopper short arm 62;

[0040] The upper end portion of the driving barrier arm 63 with an opening is hinged to the fixing portion through the fifth pin 94; the connecting plate 5 of the fixing portion is hinged to the fifth pin 94 of the driving portion;

[0041] The middle portion of the driving stop arm 63 with the through slot is hinged to the connecting rod 7 via the fourth pin shaft 93 .

[0042] In Example 4 of the present invention, Figure 1-5 As shown, the difference from the above embodiment is that:

[0043] The locking and releasing mechanism further includes: a guide rail 10, a pin sleeve 11, a tension spring 12, a linear push rod 13, and a motor bracket 14;

[0044] A connecting rod 7 is provided through the guide rail 10;

[0045] The pin sleeve 11 is sleeved on the second pin 91;

[0046] The first end of the tension spring 12 is fixedly connected to the pin sleeve 11, and the second end of the tension spring 12 is fixedly connected to the motor bracket 14;

[0047] The motor bracket 14 is fixedly connected to the linear push rod 13 , and the linear push rod 13 reciprocates along the motor bracket 14 under the drive of the tension spring 12 and the motor.

[0048] In embodiments 3 and 4:

[0049] The driving arm 63 on the upper side of the block 6 is connected to the fixed part through the fifth pin 94, and the connecting plate 5 of the fixed part is hinged to the fifth pin 94 of the driving part; the middle of the driving arm 63 is connected to the connecting rod 7 through the fourth pin 93. When the connecting rod 7 moves horizontally to the left, it drives the block 6 to rotate clockwise around the pin 92, and the hook is separated from the block.

[0050] The linear push rod 13 is connected to the connecting rod 7 through the second pin shaft 91. The output shaft of the linear push rod 13 moves horizontally to the left, driving the connecting rod 13 to move to the left together. The connecting rod 7 moves to the left to make the hook 15 rotate counterclockwise and the block 6 rotate clockwise, and the hook 15 is loosened from the block 6. The cooperation between the two can release the lifting ring 191 on the elastic body more quickly.

[0051] The pin sleeve 11 serves to fix the tension spring 12. Multiple tension springs and multiple pin sleeves 11 can be set according to the situation. For example, a pin sleeve 11 is set at the head and tail of a tension spring 12 to fix the tension spring 12. The tension spring 12 is connected to the linear push rod 13 through the second pin shaft 91, providing a continuous pre-tightening tension to the push rod shaft of the linear push rod 13, so that the push rod shaft will not move due to unstable flight or vibration of the aircraft when power is not supplied, causing the hook 15 to detach from the projectile 19 and fall, thereby causing harm.

[0052] In Example 5 of the present invention, Figure 1-5 As shown, the difference from the above embodiment is that: the bomb pod also includes a pre-tightening mechanism, and the pre-tightening mechanism includes: a compression component and a pressure transmission unit;

[0053] The compression component includes a compression spring 16, and the pressure transmission unit includes: a preload ring 17 and a preload rod 18;

[0054] The first end of the pre-tightening rod 18 is fixedly connected to the pre-tightening ring 17;

[0055] The first end of the compression spring 16 is fixedly connected to the second end of the preload rod 18, and the second end of the compression spring 16 is fixedly connected to the fixed part. The preload rod 18 can reciprocate with the first end of the compression spring 16; the second end of the compression spring 16 is fixedly connected to the compression spring cover 3 of the fixed part.

[0056] In Example 6 of the present invention, Figure 1-5 As shown, the difference from the above embodiment is that the pre-tightening ring 17 includes a curved surface that can contact the elastic body 19.

[0057] In embodiments 5 and 6:

[0058] The preload mechanism provides the missile body with a preload force of at least three times the weight of the missile, to ensure that the aircraft can still successfully drop the bomb in a flight state with a 2 times gravity acceleration. The fixed part mainly protects the internal mechanical structure and electronic components and provides support for the mechanical structure and electronic components.

[0059] The inner depression of the compression spring cover 3 is connected to the compression spring 16. The outer ring of the compression spring cover 3 has a flange connected to the support plate through bolts.

[0060] The compression spring 15 provides a preload force of at least three times the weight of the projectile to the projectile body 19. Two groups of compression springs 15 can provide a more uniform preload force, and can also provide a greater preload force, such as four or five times the weight of the projectile body 19. The compression spring adopts a rectangular helical compression spring, which has a compact structure and can provide a greater preload pressure. The compression spring 15 provides a preload force to ensure that the aircraft can still successfully drop bombs in a flight state subjected to 2 times the gravity acceleration.

[0061] In Example 7 of the present invention, Figure 1-5 As shown, the difference from the above embodiment is that: the connecting rod 7 includes a frame and a connecting rod member;

[0062] The first end of the frame is fixedly connected to the linear push rod 13;

[0063] The second end of the frame is fixedly connected to the connecting rod; the connecting rod and the L-shaped hook 15 and the H-shaped stopper 6 are hinged;

[0064] The frame contains a compression spring cover 3 fixedly connected to the compression spring 16 ; the connecting rod 7 can move relative to the compression spring cover 3 .

[0065] In this embodiment:

[0066] When the projectile is kept hoisted, the compression spring 16 is always in a compressed state, and the preload rod 18 and the preload ring 17 continuously apply downward pressure to the projectile, and the projectile is subjected to its own gravity and preload pressure, so that the projectile and the pod are separated smoothly. The interior of the connecting rod 7 is hollowed out to form a frame, which reduces the weight and allows design space for the compression spring 16 and the compression spring cover 3.

[0067] In Example 8 of the present invention, Figure 1-5 As shown, the difference from the above embodiment is that: the fixing part further includes: a housing 1, a T-shaped support plate 4, and a connecting plate 5;

[0068] The housing 1 is fixedly connected to the support plate 2 via the T-shaped support plate 4, and the connecting plate 5 is fixedly connected to the housing 1;

[0069] The support plate 2 is provided with at least two circular holes and one waist-shaped hole; a compression spring 16 passes through the circular hole;

[0070] An H-shaped stopper 6 and an L-shaped hook 15 pass through the waist-shaped hole.

[0071] In Example 9 of the present invention, Figure 1-3 As shown, the difference from the above embodiment is that: the connecting plate 5 is hinged to the fifth pin 94 of the driving part; the third pin 92 is hinged to the protrusion of the support plate 2; and the second end of the compression spring 16 is fixedly connected to the compression spring cover 3.

[0072] In embodiments 8 and 9:

[0073] The shell 1 mainly protects the internal mechanical components and electronic components. The head of the shell 1 is designed to be conical, which can reduce the impact of air resistance on the rack.

[0074] The support plate 2 has two large round holes and a waist-shaped hole, wherein the two large round holes are used to allow the compression spring to pass through, and the waist-shaped hole is used to pass the block and the hook. There are reinforcing ribs on both sides of the support plate to increase the rigidity of the support plate and reduce stress deformation.

[0075] In Embodiment 10 of the present invention, Figure 1-6 As shown, the difference from the above embodiment is that: the bomb pod includes at least one control circuit and a power supply, and the power supply is electrically connected to the motor through the control circuit. The motor drives the linear push rod 13.

[0076] In this embodiment:

[0077] The control circuit may be a microcircuit including a single chip microcomputer and an electric control switch, which can realize a controllable connection between a power source and a motor, thereby realizing circuit on and off, and further enabling the motor to drive the linear actuator.

[0078] The technical effects of this utility model are multifaceted.

[0079] In order to overcome the shortcomings of the existing technology, the present invention proposes a new type of bombing pod, which is mainly used for drone bombing. It includes a shell, a preload ring, a preload rod, a compression spring, a block, a hook, a connecting rod, a linear push rod, a tension spring, a compression spring cover, a connecting plate, a support plate, a T-shaped support, a guide rail, a motor bracket and the like.

[0080] The present invention provides a lightweight bomb-dropping pod, in which the hook, block, connecting rod, support plate and connecting plate are all designed to reduce weight, so that the overall weight of the pod is greatly reduced, which is very friendly to the load requirements of the unmanned aerial vehicle. The synchronous opening and closing of the hook and the block are controlled simultaneously by a linear push rod. The compression spring can provide thrust to push the bomb out, so that the bomb and the pod are separated smoothly. The tension spring provides a continuous pre-tightening tension to the push rod shaft, so that the push rod shaft will not move due to unstable flight or vibration of the aircraft when the linear push rod is not powered, causing the hook to detach from the bomb body and fall, thereby causing harm.

[0081] This pod has a lightweight design. The pod's hook, connecting rod, support plate, T-shaped support, and connecting plate together form the pod's skeleton, which is used to bear the gravity of the missile instead of applying the gravity of the missile to the outer shell, so that the outer shell only serves as a protective shell, greatly reducing the weight of the outer shell, and the overall weight of the pod is greatly reduced, which is very friendly to the load requirements of the drone.
