Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicle protection, in particular to a flight protection structure for an unmanned aerial vehicle. Background Art
[0002] The UAV flight protection structure is a structure designed to ensure the safety and stability of the UAV during flight. Its main purpose is to reduce or avoid damage to the UAV when it encounters unexpected situations or emergencies, and to ensure the integrity and functionality of the UAV. The UAV is usually equipped with a shock absorption system to reduce the impact during flight or landing. These shock absorption structures can include shock absorbing springs, shock absorbing foot pads, etc., which can absorb and disperse the impact force and protect the key components of the UAV. Modern UAVs are usually equipped with intelligent obstacle avoidance systems that detect and avoid obstacles through sensors and algorithms. This system can significantly improve the flight safety of the UAV and reduce damage caused by collisions. In some extreme cases, the UAV may need to make an emergency landing. At this time, a UAV equipped with an automatic parachute or other emergency landing device can land more safely and reduce losses. The UAV flight protection structure is a comprehensive design that aims to protect the safety and stability of the UAV from multiple aspects. Through reasonable structural design and material selection, the durability and service life of the UAV can be effectively improved.

[0023] Embodiment 1: This embodiment is intended to promote the solution of the problem that in the prior art drone flight protection structure, when protecting the drone, a protective bracket is mostly used for protection. When encountering an uneven place, if the protective bracket is used for parking, it is very likely to cause the drone to overturn, which is likely to cause the drone to fall. Please refer to Figure 1-Figure 6 A flight protection structure for a drone includes a protective shell 110, a connecting plate 200 is fixedly installed at the bottom of the protective shell 110, a buffer plate 180 is fixedly connected to the bottom of the connecting plate 200, a connecting rod 170 is fixedly connected to the side of the protective shell 110, a mounting frame 160 is fixedly installed on the side of the connecting rod 170, a motor 140 is fixedly installed in the middle of the mounting frame 160, a wing 130 is rotatably installed at the end of the motor 140, a protective ring 120 is fixedly connected to the side of the mounting frame 160, a mounting groove 150 is opened in the middle of the buffer plate 180, a fixing rod 210 is fixedly installed at the bottom of the mounting groove 150 and the inner wall of the mounting groove 150, a connecting piece 220 is fixedly connected to the end of the fixing rod 210, and a fixing rod 230 is fixedly installed above the connecting piece 220;
[0024] The side of the mounting rod 230 is provided with a slide groove 240 and a moving groove 410. The slide groove 240 is provided on the side of the moving groove 410. The middle of the slide groove 240 is slidably connected with a slider 250. The middle of the slider 250 is fixedly provided with a rotating shaft 320. The side of the rotating shaft 320 is hinged with a rotating rod 330.
[0025] A sliding block 400 is slidably connected in the middle of the moving groove 410 , a fixed shaft 390 is fixedly installed in the middle of the sliding block 400 , a rotating rod 360 is hinged on the side of the fixed shaft 390 , and the rotating rod 330 is cross-connected with the rotating rod 360 through the installation shaft 350 .
[0026] A mounting groove 150 is provided in the middle of the buffer plate 180, a clamping block 480 is fixedly connected to the bottom of the connecting plate 200 above the mounting groove 150, a clamping block 460 is clamped and connected at the bottom of the clamping block 480, a clamping groove 470 is provided in the middle of the clamping block 460, the clamping groove 470 is clamped and connected to the clamping block 480, a fixing plate 450 is fixedly connected to the bottom of the clamping block 460, a moving rod 440 is fixedly connected to the bottom of the fixing plate 450, a reinforcement rod 430 is inserted into the side of the moving rod 440, a fixing block 420 is fixedly connected to the side of the reinforcement rod 430, and a mounting shaft 350 is fixedly installed in the middle of the fixing block 420.
[0027] When the drone is flying, the drone itself and the wing 130 can be protected by the setting of the protective shell 110 and the protective ring 120, and the drone itself and the wing 130 can be prevented from colliding with hard objects during flight as much as possible. When the drone needs to land, the spring 270, the rotating rod 330, the rotating rod 360, and the fiber column in the middle of the buffer plate 180 can be used to squeeze the spring 270 at the moment of landing to reduce the impact force of the drone during landing. When the drone lands, the weight of the drone itself will squeeze the block 480 through the connecting plate 200. During the pressurization process, the moving rod 440 will drive the reinforcement rod 430 to press down.
[0028] When the reinforcement rod 430 is pressed down, the rotating rod 330 and the rotating rod 360 are hinged to the installation shaft 350, which will push the rotating rod 330 and the rotating rod 360 to cross and press down. During the downward pressing process, the rotating rod 330 and the rotating rod 360 will squeeze the spring 270, thereby forming a buffer to reduce the damage to the drone caused by the impact force as much as possible.
[0029] In this embodiment: through the setting of the buffer plate 180, when the drone needs to be parked after the flight, the buffer plate 180 can be used to park when encountering an uneven road surface. When parking, the drone is buffered and protected during the parking process through the setting of the rotating rod 330, the rotating rod 360, the spring 270 and the limiting column 300, thereby reducing the impact force of the drone when it lands as much as possible, greatly improving the protection of the drone itself, and also improving the service life of the drone.
[0030] Embodiment 2: This embodiment is intended to promote the solution of the problem that in the prior art drone flight protection structure, most drones do not protect the wing 130 during flight. If the wing 130 accidentally hits a branch or other hard object, it is very likely to cause damage to the wing 130, resulting in the inability to continue to use the drone. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 6 A sliding groove 340 is provided in the middle of the rotating rod 330, and a connecting groove 370 is provided in the middle of the rotating rod 360. The sliding groove 340 and the connecting groove 370 are both slidably connected with the rotating shaft 310 in the middle. The rotating shaft 310 is fixedly installed on the side of the limiting column 300. A connecting column 260 is fixedly installed in the middle of the mounting rod 230. A limiting groove 280 is provided in the middle of the connecting column 260. A spring 270 is fixedly connected in the middle of the limiting groove 280. A contact plate 290 is connected to the end of the spring 270. The limiting column 300 is fixedly connected above the contact plate 290.
[0031] In this embodiment: by setting the protection ring 120, the wing 130 can be protected as much as possible by the protection ring 120 during the flight of the drone, and the wing 130 can be avoided from touching hard objects as much as possible, which greatly improves the safety of the drone during flight. By setting the protective shell 110, the drone itself can be protected during flight, further improving the safety of the drone itself. By protecting the drone, the service life of the drone is greatly increased.
