Description

Technical Field

[0001] This utility model relates to the field of drone protection technology, and more specifically, to a drone propeller protection device. Background Technology

[0002] Unmanned aerial vehicles (UAVs) can be categorized by their flight characteristics into fixed-wing, rotary-wing, and flapping-wing types. Among these, micro-rotor-wing UAVs are characterized by their small size, simple structure, and flexible control. They can take off and land vertically, hover freely, adapt to various natural environments, and possess autonomous flight and landing capabilities. Rotor-wing UAVs are products of microelectromechanical systems (MEMS) integration, and are distinguished by their ability to take off and land vertically, hover freely, control flexibly, and adapt to various environments.

[0003] Currently, during operation, the rotor blades of rotary-wing drones are exposed to the air. When the blades collide with external objects, they are easily damaged. Additionally, the blades can be damaged by falling debris from the air. Therefore, it is necessary to propose a drone blade protection device to solve these problems. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a drone propeller protection device, which aims to improve the problem that when drone propellers collide with external objects, they are easily damaged, and at the same time, the top of the propellers may also be damaged by falling debris from the air.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a drone propeller protection device, including a drone structure and a protection structure.

[0007] The drone structure includes a drone body and a propeller support arm. The propeller support arm is fixed to the drone body, and a propeller blade is installed on the top surface of the end of the propeller support arm. The protective structure includes a support plate, a support member, and a protective member. A fixing member is fixed on the support plate and installed on the propeller support arm. The support member is fixed to the end of the support plate and a protective buffer member is installed on the support member. The protective member includes a top cap and an annular plate. A stop bar is fixed between the top cap and the annular plate. The annular plate is installed on the support member through a connecting part.

[0008] In one embodiment of this utility model, the fixing member includes an elastic clamp and a fixing plate. The elastic clamp and the fixing plate are both fixed on both sides of the support plate. The fixing plate is located between the elastic clamps. The elastic clamp is snapped onto the blade support arm. A side block is fixed on one side of the fixing plate. A threaded post is passed through the internal threads of the side block and the fixing plate. One end of the threaded post is in close contact with the blade support arm, and the other end of the threaded post is keyed to a knob.

[0009] In one embodiment of this utility model, the fixing plate and the side block are provided with threaded holes that match the threaded post.

[0010] In one embodiment of the present invention, the support member includes a sleeve and an arc-shaped plate. The sleeve is fixed to the end of the support plate, and a support plate is fixed between the sleeve and the arc-shaped plate. An arc-shaped groove is provided on one side of the arc-shaped plate.

[0011] In one embodiment of the present invention, the protective buffer includes a protective rubber sleeve and a spring. The protective rubber sleeve is fixed to one side of the arc-shaped groove, and a first connecting post and a second connecting post are sleeved and fixed at both ends of the spring. The first connecting post is fixed to the protective rubber sleeve, and the second connecting post is fixed to the inner surface of the arc-shaped groove.

[0012] In one embodiment of this utility model, the stop bar is distributed circumferentially along the annular plate, and the stop bar is inclined to one side of the annular plate.

[0013] In one embodiment of the present invention, the connecting part includes a connecting block and a connecting plate. The connecting block is fixed to the other side of the arc-shaped plate, and the connecting plate is fixed to one side of the annular plate. A screw is movably inserted through the interior of the connecting plate, and the screw is threaded into the interior of the connecting block.

[0014] In one embodiment of this utility model, the connecting plate has a circular hole inside that matches the screw, and the connecting block has a threaded hole inside that matches the screw.

[0015] The beneficial effects of this utility model are as follows: The drone propeller protection device obtained through the above design allows for the following steps: During use, the elastic clamp is secured to the propeller support arm, so that the support plate and the sleeve adhere to the lower surface of the propeller support arm. Then, by rotating the threaded column with a knob, the end of the threaded column is pressed against the propeller support arm for further fixation. The protective component is then installed onto the arc-shaped plate using the connecting part, ensuring the propeller is positioned inside the protective structure. When the drone collides with external forces due to wind deviation, the elasticity of the protective sleeve and spring effectively buffers the impact. Furthermore, when there are falling rocks above, the baffle further prevents collisions with the propeller, thus providing excellent protection for the drone. This reduces direct horizontal and vertical collisions with the propeller during use, improving safety, reducing losses due to collisions, and making it more convenient to use.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0025] Please see Figures 1-6 This utility model provides a technical solution: a drone propeller protection device, including a drone structure 100 and a protection structure 200.

[0026] Please see Figure 1 The drone structure 100 includes a drone body 110 and a propeller support arm 120. The propeller support arm 120 is fixed to the drone body 110, and a propeller is installed on the top surface of the end of the propeller support arm 120.

[0027] Please see Figures 1-6 The protective structure 200 includes a support plate 210, a support member 230, and a protective member 250. A fixing member 220 is fixed on the support plate 210 and is installed on the blade support arm 120. The support member 230 is fixed to the end of the support plate 210 and a protective buffer member 240 is installed on the support member 230. The protective member 250 includes a top cap 251 and an annular plate 252. A stop bar 253 is fixed between the top cap 251 and the annular plate 252. The annular plate 252 is installed on the support member 230 through a connecting part 260.

[0028] The fastener 220 includes an elastic clamping plate 221 and a fixing plate 222. Both the elastic clamping plate 221 and the fixing plate 222 are fixed on both sides of the support plate 210. The fixing plate 222 is located between the elastic clamping plates 221. The elastic clamping plate 221 is snapped onto the blade support arm 120. A side block 223 is fixed on one side of the fixing plate 222. A threaded post 224 passes through the internal threads of the side block 223 and the fixing plate 222. One end of the threaded post 224 is tightly attached to the blade support arm 120, and the other end of the threaded post 224 is keyed to a knob 225. The fixing plate 222 and the side block 223 have threaded holes that match the threaded post 224. Here, the elastic clamping plate 221 is used to snap onto the blade support arm 120 for positioning, and then the threaded post 224 is rotated to further compress the blade support arm 120 with the end of the threaded post 224, which can improve the stability of the installation.

[0029] The support member 230 includes a sleeve 231 and an arc plate 233. The sleeve 231 is fixed to the end of the support plate 210. A support plate 232 is fixed between the sleeve 231 and the arc plate 233. An arc groove 234 is provided on one side of the arc plate 233. The protective buffer member 240 includes a protective rubber sleeve 241 and a spring 242. The protective rubber sleeve 241 is fixed to one side of the arc groove 234. The two ends of the spring 242 are sleeved and fixed with a first connecting post 243 and a second connecting post 244. The first connecting post 243 is fixed to the protective rubber sleeve 241, and the second connecting post 244 is fixed to the inner surface of the arc groove 234. Here, when the blade collides horizontally with the outside, the elasticity of the spring 242 and the protective rubber sleeve 241 can buffer the impact, which can effectively reduce the damage to the blade caused by the collision.

[0030] The stop bar 253 is circumferentially distributed along the annular plate 252. The stop bar 253 is inclined to one side of the annular plate 252. The inclined stop bar 253 can make the gravel slide off and at the same time prevent the gravel from falling and damaging the blade. The connecting part 260 includes a connecting block 261 and a connecting plate 262. The connecting block 261 is fixed to the other side of the arc plate 233, and the connecting plate 262 is fixed to one side of the annular plate 252. A screw 263 is movably inserted inside the connecting plate 262 and is threaded into the inside of the connecting block 261. The connecting plate 262 has a round hole that matches the screw 263, and the connecting block 261 has a threaded hole that matches the screw 263. The connecting part 260 can be used to easily install the protective part 250 on the arc plate 233, improving the flexibility of use.

[0031] Specifically, the working principle of this drone propeller protection device is as follows: During use, the elastic clamp 221 is clipped onto the propeller support arm 120, so that the support plate 210 and the drag sleeve 231 fit against the lower surface of the propeller support arm 120. Then, the threaded post 224 is rotated by the knob 225, causing the end of the threaded post 224 to press against the propeller support arm 120 for further fixation. At this point, the protective component 250 is installed onto the arc-shaped plate 233 using the connecting part 260, so that the propeller blades are positioned inside the protective structure 200. When the drone deviates due to wind and collides with external forces, the elasticity of the protective sleeve 241 and the spring 242 effectively buffers the collision. Simultaneously, when there are falling rocks above, the stop bar 253 further prevents collisions with the propeller blades, thus providing excellent protection for the drone. This reduces direct collisions with the propeller blades in both horizontal and vertical directions during use, improving safety, reducing losses due to collisions, and making it more convenient to use.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
