Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and more specifically, to a mortar shell delivery device and a bomb-delivering UAV. Background Art

[0002] The rotorcraft UAV weapon system is an important branch of modern UAV technology. It integrates the characteristics of rotorcraft UAV vertical take-off and landing, hovering flight and high-precision navigation, and combines advanced weapon mounting and control technology to form an unmanned combat system with efficient strike capability. The system has high maneuverability and flexibility, can perform multiple tasks in complex environments, and provides a new combat mode for modern warfare.

[0003] Currently disclosed UAV weapon systems, such as "Puffer," "Wing Loong," and "Rainbow," generally have problems such as large fuselage size, complex bomb-dropping device structure, complex bomb loading, and high cost. The large fuselage size problem leads to poor concealment of the UAV weapon system, making it easy for the enemy to discover and inconvenient to carry; the complex bomb-dropping device structure can easily cause the UAV weapon system to be prone to bomb jams, and the complex bomb loading operation results in long preparation time on the battlefield, which can easily lead to missed opportunities. Utility Model Content

[0004] The purpose of the utility model is to provide a mortar shell delivery device and a bomb delivery drone. The mortar shell delivery device has a simple structure and is convenient to load and deliver, which saves valuable time for on-site combat. At the same time, it also greatly improves the reliability of the bomb delivery drone and reduces the risk of bomb jamming.

[0005] In order to achieve these purposes and other advantages according to the present invention, there is provided

[0006] A mortar shell delivery device, characterized by comprising:

[0007] a bomb bay, the lower end of which is open;

[0008] a support plate hinged to the lower end of the bomb bay and provided with a guide groove, through which the mortar shell body passes and the tail rests on the support plate;

[0009] The bullet locking mechanism is arranged on the bullet throwing chamber. When the bullet locking mechanism is working, the support plate can be connected and fixed to the bullet throwing chamber.

[0010] The beneficial effects of the utility model are:

[0011] In the mortar shell delivery device of the present invention, before loading, the bullet locking mechanism is in a non-working state, and the radius of the part of the mortar shell body connected to the tail fin is relatively small. This part of the shell body is sent into the guide groove from the opening of the guide groove, and then the support plate is rotated to the horizontal position. The bullet locking mechanism starts to work and connects and fixes the support plate to the bomb bay. At this time, the tail fin of the mortar shell rests on the support plate, thereby being fixed in the bomb bay, and the loading is completed. During the rotation of the support plate, the mortar shell is supported and rotated synchronously with the support plate. During the later stage of bomb delivery, it is only necessary to control the bullet locking mechanism to stop working. At this time, the support plate loses the constraint of the bullet locking mechanism and, under the action of its own gravity and the gravity of the mortar shell, will rotate relative to the bomb bay, thereby opening the lower end opening of the bomb bay, and the ammunition will fall along the guide groove of the support plate and eventually separate from the support plate, finally completing the ammunition delivery.

[0012] To sum up, the mortar shell delivery device of the present application has a simple structure, and is easy to load and deliver. It can meet the delivery needs of 60-caliber mortar shells. Its size and weight are suitable for individual combat carrying, and it has good use value and application prospects.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows:

At this time, the support plate loses its constraint and will rotate along one end under the action of its own gravity and the gravity of the mortar shell, thereby opening the lower end opening of the ammunition chamber, and the ammunition will fall along the guide groove of the support plate and eventually separate from the support plate, finally completing the ammunition delivery.

[0016] Furthermore, in the mortar shell delivery device, at least two bullet-blocking plates are provided on the inner wall of the delivery chamber at intervals. When the tail fin of the mortar shell is placed on the support plate, the bullet-blocking plates extend into the tail fin and fit with its guide fin.

[0017] The beneficial effect of adopting the above further scheme is: in this further scheme, after the upper half of the mortar shell enters the bomb bay, the mortar shell is lowered downward, and the tail of the mortar shell is placed on the support plate. At this time, the bullet stopper is located inside the tail and fits with one of the guide wings. At this time, at least two baffles are set to fix the tail to prevent the tail from rotating.

[0020] A bullet-locking socket is provided at the upper end of the support plate and is provided with a socket;

[0021] A driving unit is provided on the bomb bay and connected to the bullet locking pin. The driving unit drives the bullet locking pin to extend into or move out of the socket.

[0022] The beneficial effect of adopting the above-mentioned further scheme is: in this further scheme, the driving unit drives the bullet locking pin to move along its length direction, so that the end of the bullet locking pin extends into the socket on the bullet locking socket, or moves out of the socket. When the bullet locking pin is inserted into the socket, the support plate can be fixed, so that the support plate is connected and fixed to the bomb bay.

[0023] Furthermore, in the mortar shell delivery device, the driving unit includes:

[0024] A bomb locking servo, which is connected to the bomb bay via a bracket;

[0025] A guide seat connected to the bomb bay, wherein the bullet locking pin slidably passes through the guide seat;

[0026] A crank slider structure, wherein the output shaft of the bullet locking servo is connected to the bullet locking pin through the crank slider structure.

[0027] The beneficial effect of adopting the above-mentioned further scheme is: in this further scheme, the sliding of the lock bullet pin is limited by the guide seat to ensure that the lock bullet pin can only move along its length direction. The lock bullet pin is connected to the crank slider structure, and the two form a crank slider structure. At this time, the lock bullet servo output rotates, driving the crank slider structure to rotate, thereby driving the lock bullet pin to slide back and forth in the guide seat through the crank slider structure, thereby realizing the lock bullet pin extending into the socket or moving out of the socket.

DETAILED DESCRIPTION

[0061] The present invention will be further described in detail below with reference to the embodiments so that those skilled in the art can implement the invention with reference to the description.

[0062] It should be noted that, in the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0063] like Figures 1-6 As shown, an embodiment of the present invention provides a mortar shell delivery device, comprising:

[0064] The bomb bay 1-1 is open at its lower end and has a bomb discharge port 1-2 on its side wall. The bomb bay 1-1 is made of aviation aluminum alloy to reduce the weight of the delivery device. Furthermore, the bomb bay 1-1 can be designed with weight-reducing holes and connection mounting holes to reduce its weight.

[0065] The support plate 1-3 is hinged at one end to the lower end of the bomb chamber 1-1 by a hinge, and a guide groove 1-4 is provided at the other end. Two reinforcing ribs can be added to the lower end of the support plate 1-3 to enhance the rigidity of the support plate 1-3. The shape of the guide groove 1-4 on the support plate 1-3 is adapted to the mortar shell 7 to ensure that the upper part of the mortar shell 7 can move within the guide groove 1-4, while the tail of the mortar shell 7 cannot pass downward from the guide groove 1-4.

[0066] a bullet locking mechanism 2, which is provided on the bomb chamber 1-1; the support plate 1-3 seals the lower opening of the bomb chamber 1-1 and is connected to the bomb chamber 1-1 via the bullet locking mechanism 2; and the guide groove 1-4 is connected to the bullet discharge port 1-2;

[0067] A limiting assembly is provided in the bomb bay 1 - 1 to limit the rotation of the tail fin of the mortar shell 7 .

[0068] In this embodiment, before the mortar shell delivery device is loaded, the support plate 1-3 seals the lower end opening of the ammunition chamber 1-1, and the bullet locking mechanism 2 locks the support plate 1-3 so that the support plate 1-3 is connected and fixed to the ammunition chamber 1-1. The mortar shell 7 is arranged vertically, and the upper half of the mortar shell 7 is pushed into the ammunition chamber 1-1 until the tail of the mortar shell 7 contacts the inner wall of the ammunition chamber 1-1. During this process, the tail of the mortar shell 7 enters the ammunition chamber 1-1 from the discharge port 1-2, and the part where the body of the mortar shell 7 is connected to the tail passes through the guide groove 1-4 on the support plate 1-3. Then the mortar shell 7 is moved downward, and the tail of the mortar shell 7 is placed on the support plate 1-3. The rotation of the tail is limited by the limit assembly to prevent the tail from rotating on the support plate 1-3 when the mortar shell delivery device is moved later, thereby ensuring the stability of the connection between the ammunition chamber 1-1 and the mortar shell 7. During the later stage of bombing, it is only necessary to control the bullet locking mechanism 2 to release the support plate 1-3. At this time, the support plate 1-3 loses its constraint and rotates along one end under the action of its own gravity and the gravity of the mortar shell 7, thereby opening the lower end opening of the bomb chamber 1-1. The ammunition will fall along the guide groove 1-4 of the support plate 1-3 and finally separate from the support plate 1-3, finally completing the ammunition delivery.

[0069] In summary, the mortar shell delivery device of the present application has a simple structure, and is easy to load and deliver. It can meet the delivery requirements of 60-caliber mortar shells 7. Its size and weight are suitable for single-soldier combat carrying, and it has good use value and application prospects.

The locking pin 2-1 is connected to the crank slider 2-5 structure, and the two form a crank slider 2-5 structure. At this time, the locking servo 2-3 outputs rotation, driving the crank slider 2-5 structure to rotate, thereby driving the locking pin 2-1 to slide back and forth in the guide seat 2-4 through the crank slider 2-5 structure, thereby realizing the locking pin 2-1 extending into the socket or moving out of the socket.
