[0003] Problems with existing technology:
[0004] Existing drone collision avoidance warning devices are mostly optical cameras, which are popular because they are inexpensive and not easily damaged. However, optical cameras often fail to detect transparent glass or wires and cannot provide warnings, which may lead to further incorrect operations by the operator, putting the drone in a dangerous situation. In severe cases, collisions may occur, causing damage to the drone or even causing it to crash. In addition, drones lack necessary protective devices in the event of a collision. Utility Model Content

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0024] like Figure 1 As shown, a drone collision avoidance warning device includes: a drone 1, a warning triggering component 3 is provided on the top of the drone 1, and a warning protection ring 2 is provided on the outer side of the drone 1. The warning protection ring 2 and the warning triggering component 3 are detachably installed.
[0025] The warning triggering component 3 is independently set and connected to the drone 1 by means of glue or other means. The warning triggering component 3 and the drone 1 are connected by a data cable to transmit some simple signals. The warning protection ring 2 can rotate under the control of the warning triggering component 3 to play a certain role in protecting the drone 1. At the same time, the warning protection ring 2 can promptly feed back to the warning triggering component 3 and send a collision signal when a collision occurs.
[0026] See attached document Figures 2-4 The warning triggering component 3 includes a rubber connecting pad 301, a rotating motor 303 fixedly connected to the top of the rubber connecting pad 301, a trigger 304 fixedly connected to the output end of the rotating motor 303, a movable cavity provided inside the trigger 304, and a movable connecting tube 305 provided inside the movable cavity; multiple connecting rods 201 fixedly connected to the top of the warning protection ring 2, multiple thickness grids 202 fixedly connected to the surface of the warning protection ring 2, the multiple thickness grids 202 arranged in a ring array along the warning protection ring 2, and a polygonal pin 203 fixedly connected to the middle position of the bottom of the multiple connecting rods 201; a polygonal insertion groove 308 is opened inside the movable connecting tube 305, the polygonal pin 203 is inserted into the polygonal insertion groove 308, a disassembly screw 310 is provided on one side of the polygonal insertion groove 308, the end of the disassembly screw 310 extends into the interior of the movable connecting tube 305 and is threadedly connected to the polygonal pin 203.
[0027] According to the above structure, the rubber connecting pad 301 is fixed to the top of the drone 1 with glue, and the rotating motor 303 is powered by the ring battery 302. When the drone 1 collides, the obstacle will first come into contact with the warning protection ring 2. Under the action of the reverse force, the warning protection ring 2 will be pushed by a force, which is transmitted to the movable connecting tube 305 through the polygonal pin 203. The thickness grid 202 is used to increase the protection range and adapt to the thickness of the drone 1. The setting of the limiting spring 306 can ensure the firmness of the polygonal pin 203 and facilitate the replacement of the warning protection ring 2.
[0028] See attached document Figures 4-5 A movable ball 309 is fixedly connected to the bottom of the movable connecting tube 305. The movable ball 309 is slidably disposed with the inner wall of the movable cavity. A trigger 304 is provided with multiple spring grooves corresponding to the position of the movable connecting tube 305. Limiting springs 306 are provided inside the spring grooves. The two ends of the multiple limiting springs 306 are fixedly connected to the inner wall of the corresponding spring groove and the movable connecting tube 305, respectively. Multiple electrical pieces 307 are fixedly installed at the end of the movable connecting tube 305 corresponding to the movable cavity. The electrical pieces 307 are arranged in a ring array. Both the movable connecting tube 305 and the electrical pieces 307 are connected to a low voltage circuit.
[0029] According to the above structure, when the pushing force is transmitted to the movable connecting tube 305, the movable connecting tube 305 will rotate around the movable ball 309 as the center. During its rotation, the elastic deformation of multiple limit springs 306 generates a force opposite to the pushing force on the movable connecting tube 305, thereby pushing the drone 1 away from the obstacle. Only the warning protection ring 2 contacts the obstacle, and the drone body will not contact it. When the collision force is too large, the rotation angle of the movable connecting tube 305 increases and it contacts the electric plate 307. At this time, an electrical signal is generated and transmitted to the drone 1. The built-in program of the drone 1 controls the drone 1 to move away from the obstacle. At the same time, the trigger 304 rotates under the drive of the rotating motor 303.
[0030] The warning protection ring 2 also rotates. The hardness of the corresponding thickness grid 202 of the warning protection ring 2 is relatively low. If a severe collision occurs, it will break into small segments. Under the influence of the rotation of the warning protection ring 2, the broken ends will tilt and pierce the obstacle, thus obtaining a tilted reverse thrust. Through force analysis, a force opposite to the inertial direction of the drone 1 and a force tangential to the rotation direction of the warning protection ring 2 can be obtained. The force opposite to the inertial direction cancels out the force generated by the inertia of the drone 1, quickly decelerates the drone 1, and reduces the collision damage to the drone 1. The force tangential to the rotation direction of the warning protection ring 2 changes the direction of movement of the drone. The force originally perpendicular to the obstacle changes a certain angle of movement, which can also reduce the impact of the collision on the drone 1.
[0031] The warning protection ring 2 is equipped with a traction rope inside to connect the broken parts and prevent them from flying everywhere; the electric plate 307 in the ring array can calculate and determine the direction of the obstacle on the drone 1 by the electrical signal sent through the contact with the movable connecting tube 305; the movable ball 309 is stuck inside the movable cavity and can only rotate but cannot move.
[0032] The working principle of this utility model is as follows: The rubber connecting pad 301 is fixed to the top of the drone 1. When the drone 1 collides, the obstacle will first contact the warning protection ring 2. Under the action of the reverse force, the warning protection ring 2 will be pushed. When the collision force is too large, the movable connecting tube 305 rotates at an increased angle and contacts the electric plate 307. At this time, an electrical signal is generated and transmitted to the drone 1. The drone 1 is controlled to move away from the obstacle by the built-in program. At the same time, the trigger 304 rotates under the drive of the rotating motor 303, and the warning protection ring 2 also rotates accordingly. The hardness of the warning protection ring 2 at the corresponding thickness grid 202 is relatively low. If... In the event of a severe collision, the drone will break into small segments. Under the influence of the rotation of the warning protection ring 2, the broken ends will tilt and pierce the obstacle, thus generating a tilted, reverse thrust. Through force analysis, a force opposite to the inertial direction of the drone 1 and a force tangential to the rotation direction of the warning protection ring 2 can be obtained. The force opposite to the inertial direction cancels out the force generated by the inertia of the drone 1, quickly decelerating the drone 1 and reducing the collision damage. The force tangential to the rotation direction of the warning protection ring 2 changes the drone's direction of motion. The force originally perpendicular to the obstacle changes by a certain angle, which can also reduce the impact of the collision on the drone 1.
[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
