Description

Technical Field

[0001] This utility model relates to the field of projectile technology, specifically a continuous projectile launcher for unmanned aerial vehicles (UAVs). Background Technology

[0002] A drone dropper is a device carried by a drone that uses precise control and throwing technology to deliver relief supplies, equipment, or materials to a target area. This device is mainly used in emergency rescue, disaster relief, fire fighting, counter-terrorism and stability maintenance, etc., to improve rescue efficiency and success rate.

[0003] Utility model patent CN221367472U discloses a drone thrower, including a throw box. Multiple evenly distributed connecting columns are connected to the upper surface of the throw box, and a mounting plate is connected to the top of each connecting column. This drone thrower features feeding turntables installed in fan-shaped boxes on both sides of the throw box. Each feeding turntable has a feeding slot, and a rotating shaft is connected to its upper surface. A gear mechanism is installed in a mechanism box on the upper surface of the throw box, and a small motor connected to the rotating shaft is installed on the upper surface of the mechanism box. A pushing mechanism is also installed on the inner end face of the throw box. The two feeding turntables rotate under the action of the gear mechanism to push and throw the material hanging component. The two feeding turntables rotate repeatedly, and in conjunction with the pushing mechanism, multiple throws and continuous throws can be performed.

[0004] In the aforementioned prior art, during the use of the thrower, because the thrown items vary in type and weight, the center of gravity of both the thrower and the attached drone shifts during the throwing process. This causes the drone to tilt, affecting flight stability. Furthermore, it is not convenient to cushion and protect falling items during the throwing process, easily leading to damage or loss of the thrown items. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous drone thrower, which solves the problem that the drone's center of gravity may shift and affect flight when items are attached and thrown, and also solves the problem that it is not convenient to cushion and protect falling items.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drone continuous launcher, comprising a top plate, a plurality of mounting seats fixedly connected to the outer side of the top plate, a fixing rod fixedly connected to the bottom of the top plate, a fixing seat fixedly connected to the bottom of the fixing rod, two symmetrically distributed connecting rods fixedly connected to the bottom of the fixing seat, a plurality of friction blocks fixedly connected to the outer side of the connecting rod, a plurality of storage boxes slidably sleeved on the outer side of the connecting rod, a cover plate provided on the top of the storage box, a support mechanism provided on the storage box, and a buffer mechanism provided on the storage box.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The support mechanism 8 includes a motor 81. The motor 81 is fixedly mounted on the top of the fixed base 4. The output end of the motor 81 is rotatably connected to the fixed base 4. A sealing ring 82 is rotatably sleeved on the outer side of the output end of the motor 81. The sealing ring 82 is fixedly connected to the fixed base 4. By designing the sealing ring 82, the connection between the output end of the motor 81 and the fixed base 4 can be sealed. A bevel gear 83 is fixedly connected to the lower end of the output end of the motor 81. A bevel gear 84 meshes with the outer side of the bevel gear 83. A positive and negative screw 85 is fixedly sleeved inside the bevel gear 84. A support base 86 is rotatably sleeved on the outer side of the positive and negative screw 85. 86 is fixedly connected to the fixed base 4. The outer side of the positive and negative screws 85 is connected by two symmetrically distributed connecting blocks 87 through threads. The connecting blocks 87 are slidably connected to the fixed base 4. The top of the connecting blocks 87 is fixedly connected to the guide block 88, which is slidably connected to the fixed base 4. By designing the guide block 88, the movement of the connecting blocks 87 can be guided. The bottom of the connecting blocks 87 is fixedly connected to the connecting rod 89. The outer side of the connecting rod 89 is fixedly connected to the support block 891, which is slidably connected to the connecting rod 5. The support block 891 contacts the storage box 7. By designing the support mechanism 8, the storage box 7 can be supported.

[0024] Please see Figure 1 , Figure 2 , Figure 4The buffer mechanism 9 includes a sliding sleeve 91. Multiple sliding sleeves 91 are slidably sleeved on the outer side of the storage box 7. A buffer pad 92 is fixedly connected to the bottom of the sliding sleeve 91. A guide rod 93 is fixedly connected to the inner side of the sliding sleeve 91. A spring 94 is provided on the outer side of the guide rod 93. One end of the spring 94 is fixedly connected to the sliding sleeve 91, and the other end of the spring 94 is fixedly connected to the storage box 7. By designing the spring 94, the force of the spring 94 can act on the sliding sleeve 91. The guide rod 93 is slidably connected to the storage box 7. A slider 95 is fixedly connected to the top of the guide rod 93. The slider 95 is slidably connected to the storage box 7. A ball bearing 96 is movably sleeved inside the slider 95.

[0025] The specific implementation process of this utility model is as follows: When in use, the storage box 7 can be used to store items and materials. The support block 891 can support the storage box 7. The storage box 7 adopts a stacking design, which can maintain the stability of the center of gravity of the thrower and avoid the problem of the thrower and drone tilting due to the instability of the center of gravity, which would affect the flight operation.

[0026] When it is necessary to throw the storage box 7, the motor 81 works, and the output end of the motor 81 drives the first bevel gear 83 to rotate. The first bevel gear 83 drives the second bevel gear 84 to rotate, and the second bevel gear 84 drives the positive and negative screws 85 to rotate, causing the connecting block 87 to make a threaded movement. The two connecting blocks 87 will move in opposite directions. The connecting block 87 drives the guide block 88 to slide along the fixed seat 4. At the same time, the connecting block 87 will drive the connecting rod 89 and the support block 891 to move, so that the support block 891 separates from the connecting rod 5. At this time, the storage box 7 will move down along the connecting rod 5 under the action of gravity, so that the storage box 7 can be thrown continuously. Under the action of the friction block 6, the sliding and falling speed of the storage box 7 along the connecting rod 5 can be reduced.

[0027] When the storage box 7 falls, the cushioning pad 92 will first contact the ground and absorb a certain amount of impact. At the same time, under the action of the impact, the storage box 7 will slide along the landing slide 91. The storage box 7 will move down along the slider 95 and the guide rod 93. The storage box 7 will press down the spring 94. Under the action of the spring 94, the impact force during the fall can be further buffered, and the damage caused by the impact can be further reduced.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
