Description

Technical Field

[0001] This utility model belongs to the technical field of bombing devices, specifically relating to a bombing device for unmanned aerial vehicles (UAVs). Background Technology

[0002] With the continuous development of drone technology, its application in military and civilian fields is becoming increasingly widespread, especially in areas involving material delivery and special mission execution, where it plays a crucial role. However, in the application scenario of drones dropping munitions, traditional throwing methods have many problems.

[0003] Currently, some drones use freefall to drop munitions, which results in poor accuracy. After leaving the drone, the munitions are easily affected by various external factors such as airflow and wind direction, causing them to miss their targets. For example, in military operations, this may prevent precise strikes against target areas; in civilian emergency rescue scenarios, such as delivering relief supplies to disaster areas, it may be impossible to accurately deliver supplies to designated locations, leading to resource waste and reduced rescue efficiency. Moreover, freefall does not provide a stable initial throwing force and guidance for the munitions, and the unstable attitude of the munitions during descent further affects the dropping effect.

[0004] Therefore, there is an urgent need for a device that can improve the accuracy of drone bombing to meet the requirements for accuracy in ammunition delivery under various environmental and mission conditions. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a drone bombing device, which aims to solve the problem of low accuracy when traditional drones drop munitions.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A bomb-dropping device for unmanned aerial vehicles (UAVs) includes a bomb-dropping tube, a bomb-pushing plate, and a throwing mechanism. The bomb-dropping tube has an open bottom structure. The bomb-pushing plate is slidably connected to the bomb-dropping tube, and a launching spring is provided between the bomb-pushing plate and the bomb-dropping tube. The throwing mechanism is installed on the bomb-dropping tube and is used to fix or release the ammunition inside the bomb-dropping tube. When released, the ammunition is pushed out of the bomb-dropping tube by the bomb-pushing plate.

[0008] The launching spring is a compression spring, tension spring, or coil spring.

[0009] The bomb-throwing tube is fixed with a guide post that is slidably connected to the bomb-throwing plate.

[0010] The throwing mechanism includes a release mechanism and a fixing mechanism; the release mechanism includes a drive motor and an eccentric hook, the housing of the drive motor is fixedly connected to the grenade launcher; the output shaft of the drive motor is fixedly connected to the eccentric hook; the eccentric hook is connected to the fixing mechanism and the grenade is fixed by the fixing mechanism.

[0011] The fixing mechanism includes a hook frame and a connecting rod assembly; the hook frame is slidably connected to the grenade launcher, and the hook frame is provided with a hanging rope connected to an eccentric hook; the hook frame fixes the ammunition through the connecting rod assembly.

[0012] The linkage assembly includes a drive linkage and a fixed linkage. The fixed linkage is hinged to the throwing tube, and the two ends of the drive linkage are respectively hinged to the hook frame and the fixed linkage. The fixed linkage contacts and fixes the ammunition.

[0013] The end of the fixed connecting rod is provided with an arc-shaped groove.

[0014] The hook frame is provided with a pushing protrusion that contacts the push plate. The push plate contacts the pushing protrusion and pushes the hook frame to move.

[0015] The bomb launcher is fixedly connected to a drone mounting bracket.

[0016] The bomb-throwing tube includes an upper base, a tube body, and a lower base that are fixedly connected in sequence; the bomb-throwing tube is equipped with a battery, which is electrically connected to a drive motor via a switch.

Detailed Implementation

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0030] like Figure 1-7 The aforementioned drone bombing device includes a bombing tube 1, a bomb-pushing plate 2, and a throwing mechanism 3. The bombing tube 1 has a bottom opening structure, through which ammunition 7 can be loaded into the bombing tube 1 and dropped through the bottom opening after being thrown. In use, the bombing tube 1 can be fixedly connected to the drone body by straps, bolts, or other means.

[0031] The push plate 2 is slidably connected to the grenade launcher 1. A launch spring 4 is provided between the push plate 2 and the grenade launcher 1. During the loading of the ammunition 7, the push plate 2 will be pushed to move and the launch spring 4 will generate elastic potential energy.

[0032] The throwing mechanism 3 is installed on the bomb disposal tube 1. The throwing mechanism 3 secures or releases the ammunition 7 inside the bomb disposal tube 1. Specifically, when the ammunition 7 is loaded into the bomb disposal tube 1, the throwing mechanism 3 secures it. When the drone carries the bomb disposal tube 1 to the desired bomb disposal location, the throwing mechanism 3 releases the ammunition 7, thus releasing it. Simultaneously, during release, the launching spring 4 releases its elastic potential energy, and the pushing plate 2 pushes the ammunition 7 out of the bomb disposal tube 1.

[0033] With the above structural design, ammunition 7 will fall along the grenade launcher 1 when thrown, and will be propelled by the launch spring 4. That is, the grenade launcher 1 guides the ammunition 7 during throwing, and the launch spring 4 provides the initial propulsion. Compared to free-fall throwing, this improves the accuracy of the grenade launch.

[0034] Furthermore, the launching spring 4 can be a compression spring, tension spring, or coil spring. Regardless of the type of spring used, it is sufficient as long as elastic potential energy can be generated during the upward movement of the push plate 2, and the release of this elastic potential energy can push the push plate 2 downward.

[0035] A coil spring is preferably used, with its inner end fixedly connected to the throwing tube and its outer end fixedly connected to the push plate 2. When the push plate 2 moves upward, it pulls the outer end of the coil spring, causing the coil spring to generate elastic potential energy.

[0036] Furthermore, the push plate 2 and the bomb-throwing tube 1 can be slidably connected in various ways. For example, a guide post 5 that is slidably connected to the push plate 2 can be fixed inside the bomb-throwing tube 1.

[0037] Furthermore, the throwing mechanism 3 includes a release mechanism 30 and a fixing mechanism 31. The release mechanism 30 includes a drive motor 300 and an eccentric hook 301. The housing of the drive motor 300 is fixedly connected to the grenade launcher 1. The output shaft of the drive motor 300 is fixedly connected to the eccentric hook 301, and the rotation of the output shaft of the drive motor 300 can drive the eccentric hook 301 to rotate accordingly. The eccentric hook 301 is connected to the fixing mechanism 31 and fixes the ammunition 7 through the fixing mechanism 31. When the hook part of the eccentric hook 301 rotates upward, the ammunition 7 is fixed through the fixing mechanism 31; when the hook part of the eccentric hook 301 rotates downward or to one side, the fixation of the ammunition 7 is released. The drive motor 300 can specifically be a geared motor.

[0038] Furthermore, the fixing mechanism 31 includes a hook frame 310 and a connecting rod assembly 311; the hook frame 310 is slidably connected to the grenade launcher 1, and the hook frame 310 is provided with a hanging rope 312 connected to the eccentric hook 301; the hook frame 310 fixes the ammunition 7 through the connecting rod assembly 311.

[0039] After ammunition 7 is loaded into the grenade launcher 1, the hook bracket 310 moves upward, causing the connecting rod assembly 311 to fix the ammunition 7. After fixing, the hanging rope 312 is connected to the eccentric hook 301, and the hook part of the eccentric hook 301 is rotated upward, thereby restricting the downward movement of the hook bracket 310. When it is necessary to release ammunition 7, the hook part of the eccentric hook 301 is rotated downward, and the eccentric hook 301 is no longer hooked on the hanging rope 312, allowing the hook bracket 310 to move downward. At this time, the elastic potential energy is released by the launching spring 4, and the grenade pusher 2 pushes the ammunition 7 out of the grenade launcher 1.

[0040] Furthermore, the linkage assembly 311 includes a drive linkage 3110 and a fixed linkage 3111. The fixed linkage 3111 is hinged to the throwing tube, and the two ends of the drive linkage 3110 are respectively hinged to the hook frame 310 and the fixed linkage 3111. The fixed linkage 3111 contacts and fixes the ammunition 7.

[0041] Before loading ammunition 7, the hook frame 310 must be pushed down. During the downward movement of the hook frame 310, the fixed link 3111 will move outward of the throwing tube via the drive link 3110, thereby preventing the fixed link 3111 from blocking ammunition 7 during loading and affecting the loading of ammunition 7.

[0042] During loading, ammunition 7 is pushed upwards through the opening at the bottom of the throwing tube. As ammunition 7 moves upwards, the push plate 2 also moves upwards, generating elastic potential energy in the spring. Once ammunition 7 is in place (its lower part is higher than the end of the fixed link 3111), the hook frame 310 moves upwards, ultimately hooking the rope 312 onto the eccentric hook 301. During the upward movement of the hook frame 310, the fixed link 3111 moves inwards towards the inside of the throwing tube via the drive link 3110. At this point, the fixed link 3111 is positioned below ammunition 7, thus limiting its downward movement and providing a fixing function.

[0043] Furthermore, in order to better fit the bottom of the ammunition 7, the end of the fixing link 3111 is provided with a corresponding arc-shaped groove 3112.

[0044] Furthermore, the hook frame 310 is provided with a pushing protrusion 3100 that contacts the push plate 2. The push plate 2 contacts the pushing protrusion 3100 and pushes the hook frame 310 to move. When the push plate 2 is pushed upward by the ammunition 7, the push plate 2 will approach the pushing protrusion 3100 and eventually contact it, thus pushing the hook frame 310 upward together. That is, by setting the pushing protrusion 3100, it can play a role in linkage with the push plate, eliminating the need to push the hook frame 310 upward separately.

[0045] Furthermore, for ease of connection, a drone connector 6 is fixedly connected to the bomb launcher 1.

[0046] Furthermore, the grenade launcher 1 consists of three parts: an upper base 10, a cylinder 11, and a lower base 12. The upper base 10, the cylinder 11, and the lower base 12 are connected and fixed in sequence to form a grenade launcher.

[0047] Specifically: the drive motor 300 can be powered by a battery installed on the UAV or by a battery installed on the throwing tube. The latter is preferred; the battery is electrically connected to the drive motor 300 via a switch. When loading ammunition 7, the drive motor 300 can be controlled by pressing the switch (button switch) to rotate the eccentric hook 301.

[0048] A photosensitive unit (photoresistor) can also be set up, which is electrically connected to the power control switch and the drive motor 300. After the throwing tube is installed, the photosensitive unit is positioned under the supplementary light. When the supplementary light is turned on by the remote control terminal, the photosensitive unit receives the light's activation signal and sends a start signal to the power control switch to activate the drive motor 300.

[0049] Specifically, the following can be adopted: Figure 8 The circuit design shown is as follows: An external power supply is connected to a TP4056 via a Type-C interface. After being regulated by the TP4056 chip, DC power is provided to the system. Two LEDs are brought out to detect the charging status. The outputs of the button control circuit and the photoresistor control circuit are both connected to a switching circuit. The output of the switching circuit is connected to the base of a transistor SB050 to control its on / off state. The collector of the transistor SB050 is connected to the positive terminal of the drive motor, and its emitter is grounded. When the transistor SB050 is turned on, the drive motor operates.

[0050] The above description only describes the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments.
