Technical Field
[0001] This utility model relates to the field of drone throwing technology, specifically a drone-specific throwing structure. Background Technology
[0002] In recent years, with the rapid development of drone technology, drones have been widely used in many fields, such as patrol, security inspection, fire fighting, surveying and mapping, and search and rescue, bringing convenience and efficiency. In the field of high-altitude operations, drones can be flexibly applied to various occasions, especially in fire fighting, search and rescue and other situations where materials need to be vertically thrown, drones are often needed to throw materials at a fixed point.
[0003] Publication No. CN218777685U discloses a vertical throwing structure for drones. This patent indirectly drives the first connecting plate to rotate via a motor, which in turn drives the first connecting plate to rotate under the action of a second rotating seat. When the placing box rotates, the material inside is vertically thrown from the placing box to a predetermined location. This method of vertically throwing materials eliminates the need for hooks to suspend the material from the drone's clamping mechanism; the material is placed directly inside the placing box, thus reducing the possibility of hooks failing to detach in time, ensuring the throwing direction of the material, and reducing the possibility of the material being thrown off course. This also reduces the possibility of material being lost during vertical throwing. However, this patent still has the following problems in practical use: By rotating the placement box, materials can be vertically thrown from the box to a predetermined location. However, in actual use, the materials cannot be fixed in the placement box. When the box rotates downwards during the throwing process, the materials in the box will slide out under the force of gravity. The materials can be thrown before the box has rotated half a turn. Therefore, the throwing process cannot achieve the purpose of vertical throwing, and errors are prone to occur.
[0004] A dedicated throwing structure for UAVs is proposed to address the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide a dedicated throwing structure for drones to solve the problem mentioned in the background art. Currently, materials can be vertically thrown from the placement box to a predetermined location by rotating the placement box. However, in actual use, the materials cannot be fixed in the placement box. When the placement box rotates and the opening faces downwards during the throwing process, the materials in the placement box will slide off the placement box due to gravity. The materials can be thrown before the placement box has rotated half a revolution. Therefore, the throwing process cannot achieve the effect of vertical throwing and the throwing is prone to errors.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dedicated throwing structure for unmanned aerial vehicles (UAVs), comprising the UAV body; Also includes: The bottom of the drone body is equipped with a throwing component; The throwing assembly includes fixed plates symmetrically installed on the bottom of the UAV body, and a placement box is provided between the two fixed plates. Rotating rods are symmetrically installed on both sides of the placement box, and the rotating rods are rotatably connected to the fixed plates. One end of one rotating rod passes through one fixed plate and is fixedly installed with a rotating gear. Among them, a multi-stage electric push rod is fixedly installed on one side of the fixed plate above the rotating gear, and a movable frame is fixedly installed on the movable end of the multi-stage electric push rod. A rack is fixedly installed on one side of the movable frame, and the rack is meshed with the rotating gear. A support rod is fixedly installed on one side of the movable frame, and a positioning block is slidably connected to the lower outer side of the support rod. The positioning block is fixedly connected to the fixed plate on one side.
[0007] Preferably, the upper interior of the placement box is symmetrically provided with clamps, and movable rods are fixedly installed on the opposite sides of the two clamps. The movable rods are slidably connected to the placement box, and ball bearings are hinged to the end of the movable rods away from the clamps.
[0008] Preferably, sliding rods are symmetrically installed on both sides of the clamping plate on the movable rod, and the sliding rods are slidably connected to the placement box. A telescopic spring is sleeved on the outer side of the sliding rod, and the two ends of the telescopic spring are fixedly connected to the clamping plate and the placement box respectively.
[0009] Preferably, each of the two fixed plates is provided with a movable ring on the side near the placement box, and a semi-circular ring is fixedly installed on one side of the movable ring, with the ball bearing abutting against the semi-circular ring, and a slope is provided below one side of the semi-circular ring.
[0010] Preferably, movable rods are symmetrically installed on the opposite sides of the two movable rings, and the movable rods are slidably connected to the fixed plate. A connecting plate is fixedly installed on the end of the two movable rods away from the movable rings, and a fixed block is fixedly installed on one side of the connecting plate.
[0011] Preferably, the fixed block is internally rotatably connected to a threaded rod, one end of which is rotatably connected to a movable ring, and the other end of which is fixedly fitted with a knob. The threaded rod is also threadedly connected to the fixed plate.
[0012] Preferably, a screw is threaded to one side of the knob, and a number of positioning holes are equidistantly opened on one side of the fixing block, with one end of the screw inserted into the positioning hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This drone-specific throwing structure allows the material to be fixed in the placement box when throwing box-shaped materials. The material will not be easily thrown off during the rotation of the placement box. When the placement box rotates so that the opening faces downwards, the material can be automatically released for throwing. Vertical throwing is possible, improving the accuracy of the throwing. The specific details are as follows: 1. When throwing materials, the materials are placed in the placement box and clamped and fixed by two clamps. During the throwing process, the multi-stage electric push rod is activated via the control panel to move the movable frame downwards. During the downward movement of the movable frame, the meshing of the rack and pinion gear drives the rotating rod to rotate, causing the placement box to rotate. During the rotation of the placement box, the movable ring and the axis of the rotating rod are on the same horizontal plane, allowing the movable rod to rotate circumferentially. When the clamps are fixing the materials, the telescopic springs are in a stretched state. The rotation of the movable rod causes the ball bearings to rotate on the semi-circular ring. When the placement box rotates so that the opening is vertically downwards, the ball bearings rotate to the ramp, causing the telescopic springs to reset and drive the clamps to move. The two clamps can automatically feed the materials. When the material is released, it can be thrown vertically. When securing the material later, place the material into the box with the opening facing down and manually support it. This causes the box to rotate in the opposite direction. The ball bearings move to the ramp and push the movable rod, which moves the clamping plates and stretches the telescopic spring. This allows the two clamping plates to hold and secure the material. The box can then rotate back to its original position. This ensures that when throwing box-shaped materials into the box, the material is secured within the box and will not easily drop the material during rotation. When the box rotates so that the opening faces down, it can automatically release the material for throwing. Vertical throwing is possible, improving the accuracy of the throwing. 2. Before fixing the material, the screw can be rotated according to the size of the material to disengage it from the positioning hole. This causes the knob to lose its positioning position, allowing the screw to rotate and drive the threaded rod to rotate. After the threaded rod rotates, it can move through the threaded connection with the fixing plate, thus moving the movable ring and adjusting its position. After adjustment, the screw is reset and rotated so that one end of the screw is inserted into the adjacent positioning hole to prevent accidental rotation of the threaded rod. After the box is reset, the ball bearings abut against the semi-circular ring, allowing the movement position of the clamping plate to be adjusted. This facilitates fixing materials of different sizes and improves practicality. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-6This utility model provides a technical solution: a dedicated throwing structure for unmanned aerial vehicles (UAVs), including a UAV body 1, and a throwing assembly 2 disposed at the bottom of the UAV body 1. The throwing assembly 2 includes fixed plates 201 symmetrically installed at the bottom of the UAV body 1, and a placement box 203 is disposed between the two fixed plates 201.

The placement box 203 will not easily throw the material out during rotation. When the placement box 203 rotates so that the opening faces downward, the material can be automatically released and thrown. Vertical throwing is possible, improving the accuracy of throwing.

Movable rods 211 are fixedly installed on the opposite sides of each clamping plate 210, and the movable rods 211 are slidably connected to the placement box 203. A ball bearing 212 is hinged to the end of the movable rod 211 away from the clamping plate 210. Moving the movable rod 211 can move the clamping plates 210. Sliding rods 213 are symmetrically installed on both sides of the clamping plates 210 located on the movable rods 211, and the sliding rods 213 are slidably connected to the placement box 203. Furthermore, a telescopic spring 214 is fitted on the outer side of the sliding rod 213, and both ends of the telescopic spring 214 are fixedly connected to the clamping plate 210 and the placement box 203 respectively, so as to facilitate the reset after the clamping plate 210 moves. Each of the two fixed plates 201 is provided with a movable ring 215 on the side near the placement box 203, and a semi-circular ring 217 is fixedly installed on one side of the movable ring 215, with the ball bearing 212 abutting against the semi-circular ring 217. A ramp 218 is provided below one side of the semi-circular ring 217, so that... When the ball bearing 212 moves to the ramp 218, it allows the movable rod 211 to move.

One end of the threaded rod 221 is rotatably connected to the movable ring 215, and the other end of the threaded rod 221 is fixedly installed with a knob 222. The threaded rod 221 is threadedly connected to the fixed plate 201, which can adjust the position of the movable ring 215. A screw 223 is threadedly connected to one side of the knob 222. A number of positioning holes 224 are equidistantly opened on one side of the fixed block 220, and one end of the screw 223 is inserted into the positioning hole 224, which can position the threaded rod 221.
[0019] Working principle: Before using this drone-specific throwing structure, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 6As shown, when throwing materials, the materials are placed in the placement box 203 and clamped and fixed by two clamping plates 210. When throwing materials, the multi-stage electric push rod 205 is activated through the control panel to drive the movable frame 206 to move downward. During the downward movement of the movable frame 206, the meshing of the rack 207 and the rotating gear 204 can drive the rotating rod 202 to rotate, causing the placement box 203 to rotate. During the rotation of the placement box 203, the movable ring 215 and the axis of the rotating rod 202 are on the same horizontal plane, allowing the movable rod 211 to rotate circumferentially. When the clamping plates 210 fix the materials, the telescopic spring 214 is in a stretched state. The rotation of the movable rod 211 can cause the ball 212 to rotate on the semi-circular ring 217. When the placement box 203 rotates so that the opening is vertically downward, the ball 212 rotates to the ramp 218, causing the telescopic spring 214 to reset and drive the clamping plate 210 to move. The two clamping plates 210 can automatically release the material and throw it vertically. When fixing the material later, the material is placed in the placement box 203 with the opening facing down. The material is manually supported, causing the placement box 203 to rotate in the opposite direction. The ball bearing 212 moves to the ramp 218 and pushes the movable rod 211 to move, which can drive the clamping plates 210 to move and stretch the telescopic spring 214, so that the two clamping plates 210 can clamp and fix the material. Afterward, the placement box 203 can rotate and reset, so that when throwing the box-shaped material in the placement box 203, the material can be fixed in the placement box 203. The placement box 203 will not easily throw the material during rotation. When the placement box 203 rotates so that the opening faces down, it can automatically release the material and throw it vertically, improving the accuracy of throwing. Before fixing the material, the screw 223 can be rotated according to the size of the material, causing the screw 223 to disengage from the positioning hole 224. This causes the knob 222 to lose its positioning position, and the knob 222 can be rotated to drive the threaded rod 221 to rotate. After the threaded rod 221 rotates, it can be moved through the threaded connection with the fixing plate 201, which can drive the movable ring 215 to move. This allows the position of the movable ring 215 to be adjusted. After adjustment, the screw 223 is reset and rotated so that one end of the screw 223 is inserted into the adjacent positioning hole 224, preventing the threaded rod 221 from rotating accidentally. After the placement box 203 is reset, the ball 212 abuts against the semi-circular ring 217, allowing the movement position of the clamping plate 210 to be adjusted. This facilitates the fixing of materials of different sizes and improves practicality.
