Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and in particular relates to a unmanned aerial vehicle with an anti-collision function. Background Art

[0002] Unmanned aerial vehicle, referred to as "drone", is an unmanned aerial vehicle that is controlled by radio remote control equipment and its own program control device. When a forest fire occurs, drones are needed to take aerial photos of the fire scene to determine the scope of the fire.

[0003] When operating a drone, the drone often loses control and crashes into obstacles due to the operator's accidental touch or sudden wind. The blades of the drone are around the main body, and the blades will contact and collide with the obstacles before they do, making the blades easily damaged. Existing drones lack a mechanism to prevent the blades from collision. When the drone loses control, the blades cannot be protected. Therefore, a technical measure is proposed to solve the problem that existing drones lack a mechanism to prevent the blades from collision. When the drone loses control, the blades cannot be protected. Utility Model Content

When the drone is actually used, the anti-collision component 2 is first installed. When installing the anti-collision component 2, the position of the anti-collision component 2 is adjusted to match the position of the blade 4. Then, the drone body 1 is started to drive the blade 4 to rotate. The rotation of the blade 4 drives the drone body 1 to rise, and the drone rises to perform high-altitude reconnaissance of the fire area.

The center position of the lower surface of the pull plate 205 is connected to a connecting rod 214, and the lower end of the connecting rod 214 is connected to a lifting plate 217. The lifting plate 217 is slidably adapted to the horizontal plate 203. The lower surface of the lifting plate 217 is provided with multiple groups of evenly distributed teeth 215. The upper surface of the lifting plate 217 is installed with two groups of symmetrically distributed first springs 216. The upper end of the first spring 216 is fixedly installed above the inside of the horizontal plate 203, and the teeth 215 are snap-fitted with the slots 213. The upper end of the telescopic rod 209 is connected to a circular ring 211, and multiple groups of second springs 218 are installed inside the circular ring 211. The other end of the second spring 218 is connected to a shock-absorbing pad 212. The telescopic plate 206 is adjusted according to the size of the blade 4. The extended distance is reached, the pull plate 205 is pulled upward to drive the connecting rod 214 to move upward, the connecting rod 214 moves upward to drive the lifting plate 217 to move upward, the lifting plate 217 moves upward to compress the first spring 216, and the lifting plate 217 moves upward to drive the locking tooth 215 to disengage from the locking groove 213, thereby releasing the limit on the telescopic plate 206. At this time, the telescopic plate 206 is pulled outward, and the telescopic plate 206 moves outward to drive the bottom rod 207, the telescopic rod 209, the ring 211 and the shock-absorbing pad 212 to move outward. When the ring 211 does not hinder the blade 4, the pull plate 205 is released, and driven by the rebound of the first spring 216, the locking tooth 215 on the lower surface of the lifting plate 217 clamps the locking groove 213 to complete the limit on the telescopic plate 206, and then the telescopic plate 206 is adjusted according to the height of the blade 4. The height of the ring 211 and the shock-absorbing pad 212 is adjusted, and the limit of the telescopic rod 209 by the fastening bolt 208 is released, and then the telescopic rod 209 is moved up and down. When the height of the shock-absorbing pad 212 and the ring 211 is adapted to the blade 4, the telescopic rod 209 is fixed with the fastening bolt 208, and then the plug plate 202 is aligned with the socket 6 in the connecting plate 5 and inserted, and then the bolt is screwed into the threaded hole 204 to complete the installation of the anti-collision component 2. When the operator accidentally touches it or the wind blows suddenly, causing the drone to lose control and crash into an obstacle, the shock-absorbing pad 212 contacts the obstacle first, and the shock-absorbing pad 212 can absorb part of the impact force, reducing damage to the drone body. Then the shock-absorbing pad squeezes the second spring 218, and the second spring 218 further absorbs the impact force.

[0026] Working principle: When the drone is actually used, the anti-collision component 2 is first installed. The specific method is to adjust the extension distance of the telescopic plate 206 according to the size of the blade 4, pull the pull plate 205 upward to drive the connecting rod 214 to move upward, and the connecting rod 214 moves upward to drive the lifting plate 217 to move upward, and the lifting plate 217 moves upward to compress the first spring 216, and the lifting plate 217 moves upward to drive the locking tooth 215 to disengage from the slot 213, thereby releasing the limit on the telescopic plate 206. At this time, the telescopic plate 206 is pulled outward, and the telescopic plate 206 moves outward to drive the bottom rod 207, the telescopic rod 209, the ring 211 and the shock-absorbing pad 212 to move outward. When the ring 211 does not hinder the blade 4, release the pull plate 205. Driven by the rebound of the first spring 216, the locking tooth 215 on the lower surface of the lifting plate 217 clamps the slot 213 to complete the limit on the telescopic plate 206. Then, the height of the ring 211 and the shock-absorbing pad 212 is adjusted according to the height of the blade 4, the limit of the telescopic rod 209 by the fastening bolt 208 is released, and then the telescopic rod 209 is moved up and down. When the height of the shock-absorbing pad 212 and the ring 211 is adapted to the blade 4, the telescopic rod 209 is fixed with the fastening bolt 208, and then the plug plate 202 is aligned with the socket 6 in the connecting plate 5 and inserted, and then the bolt is screwed into the threaded hole 204 to complete the installation of the anti-collision component 2. Through the setting of the anti-collision component 2, the anti-collision component 2 is movably connected to the drone body 1, which is convenient for replacing the anti-collision component 2, and the anti-collision component 2 can flexibly adjust the height of the shock-absorbing pad 212 and the ring 211 according to the size and height of the blade 4, so that the ring 211 and the shock-absorbing pad 212 are always on the outside of the blade 4, thereby ensuring the anti-collision effect and the protection effect of the blade 4;

[0027] Then, the drone body 1 is started to drive the blades 4 to rotate. The rotation of the blades 4 drives the drone body 1 to rise. The drone rises to conduct high-altitude reconnaissance of the fire area. When the operator accidentally touches the drone or a sudden wind blows, causing the drone to lose control and crash into an obstacle, the shock-absorbing pad 212 contacts the obstacle first. The shock-absorbing pad 212 can absorb part of the impact force and reduce damage to the drone body. Then the shock-absorbing pad squeezes the second spring 218, and the second spring 218 further absorbs the impact force. Through the use of the shock-absorbing pad 212 and the second spring 218, the impact force is effectively absorbed to prevent damage to the drone body.
