Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of drone-mounted grenade throwing technology, specifically a drone-mounted grenade throwing device. Background Technology
[0002] Drones can be used for reconnaissance and attack missions against enemy targets, such as carrying small bombs and grenades to precisely strike enemy equipment, personnel, and fortifications. Currently, there are many types of grenade throwing systems using mounting units, but most throwing mechanisms simply release the grenade by using its own weight to pull out the pull ring. However, not all grenade pull rings are pulled out directly; some grenades, for safety reasons, require twisting to pull out, making direct gravity release impossible. Current systems employ multi-motor combined drive structures, where the twisting and pulling of the pull ring and the grenade release are accomplished through the combined action of multiple motors. This structure is more complex, increasing the risk of mechanical failure and adding to the overall weight, significantly reducing the drone's maneuverability and range. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a grenade-loading device for drones. It can achieve the grenade twisting and releasing actions through a servo motor, and has a simple structure, lighter weight, and less loss of drone range.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A grenade-loading device for unmanned aerial vehicles (UAVs) includes a mounting shell, a mounting slot at the bottom of the mounting shell that conforms to the outline of the grenade, a connection structure at the top of the mounting shell for connecting with the UAV, a servo motor at one end of the mounting shell, a rotating pull ring mechanism at the bottom of the servo motor, and a release mechanism at the bottom of the mounting slot that conforms to the mounting slot. The servo motor is used to drive the rotating pull ring mechanism and the release mechanism in a coordinated manner.
[0006] Specifically, the rotating pull ring mechanism is coaxially arranged with the output shaft of the servo motor, and an opening is provided at the bottom of the rotating pull ring mechanism, which is adapted to the pull ring of the grenade.
[0007] Specifically, the release mechanism is a strap, one end of which is fixedly connected to one side of the mounting housing, and the other end of which has a buckle. The mounting housing has a slot adapted to the buckle and a slide rail that passes through the slot. The release mechanism also includes a linkage structure, which includes a swing link and a pin. The pin slides with the slide rail and engages with the buckle. The swing link engages with the pin and is linked to a rotating pull ring mechanism. When the rotating pull ring mechanism rotates, the swing link swings synchronously, causing the pin to be pulled outward and disengaged from the buckle.
[0008] Specifically, the end of the insertion pin has a mating groove, one end of the swing link is hinged to the mounting housing, and the other end of the swing link is slidably engaged with the mating groove.
[0009] Specifically, a drive disc is provided at the top of the rotating pull ring mechanism, and a linkage pin is vertically arranged on the drive disc. The inner side of the swing link is adapted to the linkage pin.
[0010] Specifically, the grenade is placed flat in the mounting slot, with the grenade's safety pin abutting against one side of the mounting slot, and the grenade's pull ring facing the direction of the pull ring mechanism.
[0011] Specifically, the connection structure is a sliding installation structure, and the mounting shell is detachably slidably installed with the slot on the UAV through the sliding installation structure.
[0012] Specifically, the sliding mounting structure is a slider with a top width greater than its bottom width.
[0013] Compared with the existing technology, the beneficial effects of this utility model are:
[0014] This invention solves the problem of releasing a twisted pin grenade, and has a simple and practical structure with stable operation.
[0015] This invention utilizes a structure linking a swing linkage and a rotating pull ring mechanism, achieving both the grenade twisting and release actions with a single servo motor. This reduces control complexity, simplifies the control and power structures, and contributes to weight reduction, allowing the drone to travel further, fly faster, and achieve better combat effectiveness. The linkage structure also offers a faster response time, reducing grenade release time. When the rotating pull ring mechanism rotates, the swing linkage swings synchronously, causing the pin to pull outwards and disengage from the latch. This linkage action quickly and effectively releases the grenade, ensuring structural stability and reducing the likelihood of malfunctions or jamming, making it more suitable for use in harsh environments.

[0023] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0024] like Figure 1-5 As shown, the UAV-mounted grenade throwing device of this utility model includes a mounting shell 1, which is mounted on the bottom of the UAV via a connecting structure 12. The UAV drives the device to perform the throwing action. The mounting shell 1 can have a built-in battery to power the servo motor, or it can be directly connected to the UAV via wiring and powered by the UAV's power supply. A controller can be mounted on the mounting shell 1 as a signal receiving unit and motion control unit to control the movement of the servo motor 2. Alternatively, it can be connected to the UAV via wiring, with the UAV's controller synchronizing signal transmission and motion control.
[0025] In this embodiment, the connecting structure 12 is a sliding installation structure, and the mounting housing 1 is detachably slidably installed with the slot on the UAV through the sliding installation structure. Specifically, the sliding installation structure is a slider with a top width greater than its bottom width, preferably a wedge-shaped slider or a T-shaped slider as the connecting component. The corresponding sliding groove assembly is fixed to the bottom of the UAV with bolts, and the installation and removal of the mounting unit can be quickly completed through sliding engagement, improving maintenance efficiency.
[0026] The bottom of the mounting housing 1 is provided with a mounting groove 11 corresponding to the outline of the grenade. The grenade is placed flat in the mounting groove 11, with the safety plate of the grenade abutting against one side of the mounting groove 11, and the pull ring of the grenade facing the direction of the rotating pull ring mechanism 3. When the grenade is released, it falls downwards under the action of gravity, ending the disintegration of the safety plate restricted by the mounting groove 11, and the grenade is fully triggered.
[0027] A servo motor 2 is installed at one end of the mounting housing 1, and a rotating pull ring mechanism 3 is installed at the bottom of the servo motor 2. A release mechanism 4 adapted to the mounting slot 11 is installed at the bottom of the mounting slot 11. The servo motor 2 is used to drive the rotating pull ring mechanism 3 and the release mechanism 4 to work together. When the servo motor 2 is remotely controlled, it operates the rotating pull ring mechanism 3 to swing at a certain angle, and at the same time, it activates the release mechanism 4 to release the grenade while completing the twisting and pulling of the pin, thus triggering the grenade.
[0028] Specifically, the rotating pull ring mechanism 3 is coaxially mounted with the output shaft of the servo motor 2. The bottom of the rotating pull ring mechanism 3 has an opening 31, which engages with the pull ring of the grenade. When placing the grenade, the pull ring is inserted into the opening 31 for fixation. The servo motor 2 then drives the rotating pull ring mechanism 3 to swing at a certain angle, causing the pull ring to disengage.
[0029] Specifically, the release mechanism 4 is a strap, which is a flexible strap. One end of the strap is fixedly connected to one side of the mounting housing 1, and the other end of the strap has a buckle 41. The mounting housing 1 has a slot 13 corresponding to the buckle 41, and a slide 14 that passes through the slot 13. The opening of the slide 14 is located on the front side where the servo 2 is located. A pin 52 is slidably fitted inside the slide 14. The pin 52 slides inside the slide 14 and can pass through the buckle 41 to fix the strap, so that the strap passes around the bottom of the grenade to fix the grenade. When the grenade needs to be released, the pin 52, under the action of the servo 2, slides outward through the drive of the linkage component until it disengages from the buckle 41. Under the action of gravity, the buckle 41, along with the strap, loosens its restraint on the grenade, and the grenade is released. The linkage structure 5 converts the drive of the servo motor 2 on the rotating pull ring mechanism 3 into the sliding of the plug pin 52. The linkage structure 5 also includes a swing link 51. The end of the plug pin 52 has a mating groove 53. One end of the swing link 51 is hinged to the mounting housing 1, and the other end of the swing link 51 is slidably engaged with the mating groove 53. A drive disk 32 is provided on the top of the rotating pull ring mechanism 3. A linkage pin is vertically provided on the drive disk 32. The inner side of the swing link 51 is in contact with the linkage pin. When the drive disk 32 rotates with the rotating pull ring mechanism 3, the linkage pin pushes the swing link 51 to swing outward. When the drive disk 32 is driven by the servo motor 2 to rotate at a certain angle with the rotating pull ring mechanism 3, the linkage pin pushes the swing link 51 to swing outward. At the same time, by utilizing the amplification effect of the swing link 51, the distal end of the swing link 51 drives the plug pin 52 to slide outward, thereby allowing the plug pin 52 to disengage from the buckle 41 and release the strap.
[0030] This invention utilizes a structure linking the swing linkage 51 with the rotating pull ring mechanism 3, achieving both the grenade twisting and release actions using only a single servo motor 2. This simplifies control complexity, streamlines the control and power structures, and reduces weight, allowing the UAV to travel further, fly faster, and achieve better combat effectiveness. The linkage structure also offers a faster response time, reducing grenade release time. When the rotating pull ring mechanism 3 rotates, the swing linkage 51 swings synchronously, causing the insertion pin 52 to pull outwards and disengage from the latch 41. This linkage action quickly and effectively releases the grenade, ensuring structural stability and reducing the likelihood of malfunctions or jamming, making it more suitable for use in harsh environments.
