[0027] The following is a more detailed description of an automatic bomb-dropping device of the utility model in conjunction with a schematic diagram, in which a preferred embodiment of the utility model is shown. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0028] like Figure 1 and 2 As shown, an automatic bomb dropping device is fixed under a drone, comprising a main body 1, through holes 2 are arranged on the upper surfaces of the left and right sides of the main body 1, a placement groove 3 is recessed between the two through holes 2, and the left and right sides of the placement groove 3 are respectively connected to the two through holes 2. The placement groove 3 is used to place a clamping mechanism for clamping a projectile, a driving mechanism for driving the clamping mechanism to clamp the projectile, and an elastic mechanism for retracting the clamping mechanism.

[0029] The driving mechanism is arranged in the center of the placement slot 3, and includes a rotor 4 and a motor. The rotor 4 is an elliptical plate, the center of which is meshed and connected through a rotating shaft 5 and movably fixed to the bottom surface of the placement slot 3. The rotating shaft 4 is meshed and connected with the output shaft of the motor. When the motor is started, the output shaft rotates, driving the rotating shaft 4 to rotate, thereby causing the elliptical plate to rotate.

[0030] There are two clamping mechanisms, which are respectively arranged on the left and right sides of the elliptical plate, and are arranged between the two through holes 2 and the elliptical plate. The two clamping mechanisms have the same structural arrangement, including a clamping plate 8, an arc plate 6 and a guide plate 7. The clamping plate 8 is relatively close to the through hole 2, and the arc plate 6 is in abutment with the rotor 4. The clamping plate 8 is connected to the arc plate 6 through a guide rod 7. The end faces of the two side ends of the arc plate 6 and the clamping plate 8 that are away from each other are both arranged as arc surfaces, and the two arc surfaces are respectively matched with the side walls of the through hole 2 and the elliptical plate. When the elliptical plate rotates and the two ends of its long axis abut against the arc plate 6, the two clamping plates 8 extend into the interior of the two through holes 2 respectively to achieve clamping of the projectile.

[0031] The placement slot 3 has recessed receiving slots on the front and rear side walls of each clamping mechanism. The elastic component is arranged in the receiving slot and the placement slot 3, which includes a connecting member 9 and a spring. The bottom end of the connecting member 9 abuts against the left side (upper surface) of the arc plate 6, and a support plate 10 is integrally extended toward the receiving slot from the side surface close to one side of the receiving slot. The bottom surface (right side) of the support plate 10 abuts against the right side wall of the receiving slot, and a guide pin 11 is arranged on the left side (upper surface). Corresponding to the guide pin 11, a similar guide pin is integrally extended from the left side of the receiving slot. A spring is arranged between the two guide pins, and the two ends of the spring are arranged on the periphery of the two guide pins 11. Reference Figure 2 When the two ends of the long axis of the rotor 4 abut against the arc plate 6, the arc plate 6 is forced to move toward the through hole 2, and squeezes the spring of the elastic device, and clamps the projectile in the through hole 2. When the rotor 4 rotates again, the spring of the elastic device is less stressed and stretches, so that the clamping plate 8 and the arc plate 6 move toward the rotor 4, and the projectile is released, until the two ends of the short axis of the rotor 4 abut against the arc plate 6, refer to Figure 1 .

[0032] In order to accommodate elastic bodies of different diameters, a spring is also provided between the arc plate 6 and the clamping plate 8 .

[0033] The specific structure is as follows: a slide groove 12 is concavely formed on the side of the connecting plate 9 facing the arc plate 6, and corresponding to the slide groove 12, sliders 13 are integrally extended outwardly from the two sides of the bottom end of the clamping plate 8, and the sliders 13 are slidably arranged in cooperation with the slide groove 12. A guide hole is concavely formed on the end surface of the clamping plate 8 facing the arc plate 6, and one end of the guide rod 7 is inserted into the guide hole, and the other end is fixed to the side end surface of the arc plate 6. A spring is arranged on the outer periphery of the guide rod 7, one end of which abuts against the front side surface of the arc plate 6, and the other end abuts against the rear side surface of the clamping plate 8, and does not extend into the guide hole.

[0034] In order to ensure the stability of the connection between the clamping plate 8 and the arc plate 6, we set two guide rods 7 in each clamping structure, and the number of guide holes is two, and the two guide holes are equidistantly arranged on the side of the clamping plate 8.

[0035] refer to Figure 3 On the bottom surface of the main body, at the periphery of the through hole 2, a guide ring 15 is integrally extended downward to improve the accuracy of the direction in which the projectile falls.

[0036] In order to fix the motor, we set up a top cover 14, and a motor placement slot is provided inside the top cover 14. The motor is fixed inside the motor placement slot. The left and right sides of the motor placement slot are provided with bumps for limiting the vertical jump of the clamping mechanism. The top cover 14 is provided with threaded holes at the four corners, and the top cover 14 is detachably fixed to the top of the rotor 4 by bolts.

[0037] In the present utility model, the installation sequence of each mechanism is:

[0038] Step 1: Take out the main body 1 of the automatic bombing device.

[0039] Step 2: Place the connecting member 9 into the placement groove, and extend its supporting plate 10 into the receiving groove.

[0040] Step 3: Connect the arc plate 6 and the clamping plate 8 through the guide rod 7, and install a spring of appropriate length.

[0041] Step 4: Place the assembled clamping mechanism inside the receiving groove and place it in conjunction with the connecting piece 9.

[0042] Step 5: Install springs of appropriate length between multiple guide pins 11.

[0043] Step 6: The rotor 4 is meshed and connected with the rotating shaft 5 and movably fixed between the two arc-shaped plates 6 through the rotating shaft 5 , and the two ends of the short shaft of the rotor 4 are abutted against the side walls of the arc-shaped plates 6 .

[0044] Step 7: embed the motor into the top cover 14 and cover the top cover 14. After covering the top cover 14, the output shaft of the motor is meshed and connected with the rotating shaft 5, and the bolts of the top cover 14 are tightened to fix the top cover 14 and the main body 1.

[0045] A controller is also provided inside the top cover 14, and the controller is connected to the drone controller signal, and the controller is used to control the start and stop of the motor.
