Description

Technical Field

[0001] This utility model relates to the field of drone throwing equipment technology, specifically to a drone thrower for emergency rescue. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are vertical takeoff and landing unmanned aircraft that can be remotely controlled by radio or autonomously controlled from the ground. In the past decade or so, with the research progress in composite materials, power systems, sensors, and especially flight control technologies, unmanned helicopters have developed rapidly and are increasingly becoming the focus of attention.

[0003] In related technologies, in order to enable drones to carry items for emergency rescue work, quick-release modules and throwing devices are usually installed on the bottom of the drone's fuselage. Emergency items are then manually attached to the throwing device. For example, mechanical grippers, electric suction devices, or cylinders are installed on the bottom of emergency rescue drones to suspend emergency items for throwing operations.

[0004] However, existing throwing devices, such as cylinder-suspended throwing devices, will experience increased stress on the piston rod of the cylinder due to the load and gravity after prolonged suspension, which will reduce the lifespan of the throwing device. To solve the above problems, a drone throwing device for emergency rescue is proposed. Utility Model Content

[0005] In view of this, the present invention provides a drone launcher for emergency rescue. The present invention connects the launching device with the connecting component, so that the sliding block is inserted into the movable groove and the support block is inserted into the limiting groove. The limiting groove is rotated by the rotating shaft, which in turn causes the connecting plate connected to the limiting groove to rotate, so that the plug block and the receiving groove are aligned and the connecting plate is supported without the connection of the electric lifting rod, thereby reducing the stress on the motor and the electric lifting rod and improving the service life of its components.

[0006] To address the aforementioned technical problems, this utility model provides a drone thrower for emergency rescue, comprising a quick-release module at the bottom of the drone, a thrower frame at the bottom of the quick-release module, a support plate on the lower surface of the quick-release module, a thrower box in the middle of the support plate, a thrower device inside the thrower box, a connecting groove at the bottom of the thrower box, a limiting ring groove fixedly provided in the inner ring of the connecting groove, multiple receiving grooves opened in the limiting ring groove, and an opening on the adjacent side of each receiving groove.

All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1-5As shown: This embodiment provides a drone thrower for emergency rescue, including a quick-release module 100 located at the bottom of the drone. The quick-release module 100 connects a support plate 102 to the throwing device 200 and the drone. A throwing rack 101 is located at the bottom of the quick-release module 100, which is used to mount emergency supplies to be thrown. A support plate 102 is located on the lower surface of the quick-release module 100, which connects the quick-release module 100 to a throwing box 103. The throwing box 103 is located in the middle of the support plate 102. The throwing device 200 is installed inside the throwing box 103 to connect it to the drone. The throwing device 200 is used to launch the throwing frame 101. A connecting groove 300 is provided at the bottom of the throwing box 103. The connecting groove 300 connects the limiting ring groove 301 to the support plate 102. A limiting ring groove 301 is fixedly provided inside the connecting groove 300. The limiting ring groove 301 and the connecting groove 300 are heat-fused together. The limiting ring groove 301 is used to form a receiving groove 302, thereby supporting the insertion block 305. Multiple receiving grooves 302 are provided within the positioning annular groove 301. These grooves 302 receive the insertion block 305, thereby connecting the connecting groove 300 to the connecting plate 304. Each receiving groove 302 has an opening 303 on its adjacent side. The opening 303 is larger than the insertion block 305 and penetrates the bottom of the connecting groove 300, communicating with the positioning annular groove 301. The opening 303 allows the insertion block 305 to enter the connecting groove 305. A connecting plate 304 is fixedly mounted on the upper surface of the throwing frame 101. The connecting plate 304 and the throwing frame 101 can be heat-fused or connected via... The bolted connection is used for fixing. The connecting plate 304 is used to install the connecting component 400 and the fixed plug block 305. The connecting plate 304 is also used to connect the throwing frame 101 and the support plate 102. The connecting component 400 is provided on the upper surface of the connecting plate 304.

The plug block 305 is adapted to the receiving groove 302.

[0024] In use, the plug-in block 305 enters the connecting groove 300 through the opening 303. By activating the electric lifting rod 201 in the throwing device 200, the linkage plate 202 and the motor 203 move up and down, causing the rotating shaft 204 installed at the bottom of the motor 203 to insert into the limiting ring 401. Then, by inserting the sliding block 205 into the movable groove 403, the support block 206 is slidably inserted into the limiting groove 402. The rotating shaft 204 drives the limiting groove 402 to rotate, causing the connecting plate 304 connected to the limiting groove 402 to rotate, so that the plug-in block 305 corresponds to the receiving groove 302. Then, the electric lifting rod 201 descends, causing the connecting plate 304 to connect with the limiting ring groove 301. This allows the connecting plate 304 to be supported without the connection of the electric lifting rod 201, thereby reducing the stress on the motor 203 and the electric lifting rod 201 and improving the service life of its components.

[0031] The effect is as follows: the sliding block 205 is used to move within the movable groove 403, and the support block 206 is used to fill into the limiting groove 402, thereby connecting the connecting plate 304 with the rotating shaft 204, thus connecting the throwing frame 101 with the throwing device 200.

[0032] like Figure 2 , 3As shown in Figure 5: A movable opening 500 is provided at the front of the groove of the limiting groove 402. The movable opening 500 penetrates the ring wall of the limiting ring 401. The movable opening 500 is used for the baffle 501 to move back and forth.

[0036] Working principle: The plug-in block 305 enters the connecting groove 300 through the opening 303. Activating the electric lifting rod 201 within the throwing device 200 drives the linkage plate 202 and motor 203 to move up and down, causing the rotating shaft 204 mounted at the bottom of the motor 203 to insert into the limiting ring 401. Then, by inserting the sliding block 205 into the movable groove 403, the support block 206 is slidably inserted into the limiting groove 402. The electric push rod 502 drives the baffle 501 to seal and limit the support block 206 within the limiting groove 402. The rotating shaft 204 drives the limiting groove 402 to rotate, causing the connecting plate 304 connected to the limiting groove 402 to rotate, thus aligning the plug-in block 305 with the receiving groove 302. Finally, the electric lifting rod 201 descends, thereby... The connecting plate 304 is connected to the limiting ring groove 301, so that the connecting plate 304 can be supported without the connection of the electric lifting rod 201. This reduces the stress on the motor 203 and the electric lifting rod 201 and improves the service life of their components. When throwing is required, the electric lifting rod 201 rises, which pulls the connecting plate 304 up. Then, the motor 203 rotates in the opposite direction, which moves the plug block 305 towards the opening 303. After it moves into place, the baffle 501 is reset, and the electric lifting rod 201 descends, so that the opening 303 and the connecting plate 304 are horizontally limited by the limiting ring groove 301. Then, the motor 203 drives the rotating shaft 204 to rotate, which pulls the support block 206 out of the limiting groove 402. At this time, the throwing operation is completed.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
