Description

Technical Field

[0001] This invention relates to the field of drone technology, and more specifically to a detachable portable drone grenade release device and its method of use. Background Technology

[0002] Hand grenades are small, hand-thrown munitions used for both offense and defense, and are among the most widely used and consumed types of ammunition. They can kill personnel and damage tanks and armored vehicles. Unmanned aerial vehicles (UAVs) are increasingly prevalent in the military field, performing reconnaissance and strike missions. Their mobility, flexibility, and non-contact warfare advantages are one of the driving forces behind the emergence of new combat modes. Currently, various UAV-borne throwing devices exist, but most have simple structures and limited throwing motions.

[0003] The closest existing technical solution is CN107514933A, a UAV grenade launching device. This device is a single-compartment launcher, using a vertical pod as the grenade storage compartment. A spring is fixed to the bottom of the compartment to provide the power for grenade release and storage. The bottom uses a compartment door and a compartment door unlocking mechanism for unlocking. A pre-drilled slot for a pull ring is provided on the side of the compartment to work with the safety release mechanism to pull the grenade safety. This technical solution can only hold one grenade, which is slightly insufficient for battlefield strike capability. Using a spring as the storage and release force requires different spring preloads for different grenade models. The unlocking mechanism of the compartment door has specific release time requirements and requires a separate power source to unlock the compartment door. The grenade must be aligned with the pre-drilled slot for the pull ring to ensure the safety release mechanism works smoothly and the grenade pull ring is released successfully. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a detachable and portable drone grenade release device that requires only one servo motor to meet all power needs and can simultaneously mount and release two grenades in stages.

[0005] The present invention adopts the following technical solution.

[0006] On one hand, the present invention provides a detachable portable unmanned aerial vehicle (UAV) grenade release device, including a mounting bracket, a grenade storage compartment, a servo motor mounting bracket, a servo motor, a servo motor rocker arm, a rocker arm column, a grenade pull cord, and a grenade pull cord limiting bracket. The grenade storage compartment includes a first grenade storage compartment and a second grenade storage compartment; the rocker arm column includes a first rocker arm column and a second rocker arm column; the grenade pull cord includes a first grenade pull cord and a second grenade pull cord; the grenade pull cord limiting bracket includes a first grenade pull cord limiting bracket and a second grenade pull cord limiting bracket.

[0007] The grenade is placed inside the grenade magazine, and the pull ring on the grenade is placed along the fixing grooves on both sides of the grenade magazine;

[0008] The lower ends of the mounting bracket are provided with a first grenade securing compartment and a second grenade securing compartment. The grenade pull ring in the first grenade securing compartment is connected to one end of the first grenade pull rope, and the other end of the first grenade pull rope passes through the first grenade pull rope limiting frame and is connected to the first rocker arm column. The grenade pull ring in the second grenade securing compartment is connected to the second grenade pull rope, and the second grenade pull rope passes through the second grenade pull rope limiting frame and is connected to the second rocker arm column.

[0009] The rocker arm column is mounted on the servo rocker arm, the servo rocker arm is connected to the servo, and the servo is located inside the servo mounting bracket;

[0010] The entire device is fixed to the bottom of the drone via bolt holes on the bracket.

[0011] Furthermore, the servo mounting bracket is located in the middle of the bottom of the bracket and is used to limit and fix the servo.

[0012] Furthermore, the servo rocker arm is fixed to the servo and rotates with the servo output shaft.

[0013] Furthermore, the extended end of the servo rocker arm is provided with a first rocker arm column, and a second rocker arm column passes through the servo rocker arm and is screwed into the servo output shaft for fixation.

[0014] Furthermore, the initial position of the servo rocker arm is that the extended end is located in a horizontal position on the left side of the servo.

[0015] Furthermore, the servo motor drives the servo motor rocker arm to rotate counterclockwise.

[0016] Furthermore, the first grenade pull cord limiting clamp and the second grenade pull cord limiting clamp limit the first grenade pull cord and the second grenade pull cord.

[0017] Furthermore, the grenade magazine, grenade pull cord limit bracket, and servo motor mounting bracket are connected to the hanger via bolt holes on the top.

[0018] Furthermore, the grenade magazine is used to store grenades and to limit their movement.

[0019] On the other hand, this patent provides a method of using a detachable portable drone grenade release device, including:

[0020] S1: Place the grenade in the grenade magazine, and position the pull ring on the grenade along the specific fixing groove;

[0021] S2: Secure the grenade release device to the bottom of the drone using the bolt holes on the bracket;

[0022] S3: The battery powers the servo motor, the control board provides a signal to the servo motor, and the servo motor begins to rotate counterclockwise.

[0023] S4: The servo arm on the servo motor rotates 90 degrees counterclockwise from the horizontal position on the left. The first grenade pull cord pulls the grenade ring in the first grenade magazine, disengaging from the grenade. The grenade loses its vertical restraint and falls freely, completing the release of the first grenade. The servo arm continues to rotate counterclockwise from the vertical downward position. When it rotates to the horizontal position on the right, the first arm column begins to support the second grenade pull cord. The servo arm continues to rotate counterclockwise, causing the second grenade pull cord to bend and deform, thereby pulling the grenade ring in the second grenade magazine to disengage from the grenade. The grenade loses its vertical restraint and falls freely, completing the release of the second grenade.

[0024] The beneficial effects of this invention are compared with those of the prior art:

[0025] 1. It eliminates the reliance on springs, and there is no need to consider the spring models required for different grenades;

[0026] 2. The power module is simplified, requiring only one servo motor to meet all power needs;
