Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV collision protection structure. Background Technology
[0002] A drone is an aircraft that does not require human piloting and completes flight missions through remote or autonomous control. It combines aviation technology, electronic communication, sensors, and artificial intelligence, and is widely used in military, civilian, and scientific research scenarios. It achieves ascent, descent, translation, and steering by adjusting the speed difference of multiple propellers (such as quadcopters and hexacopters), relying on the "reaction force" principle in aerodynamics.
[0003] The applicant discovered through a search that a Chinese patent discloses "A Collision Protection Device for Unmanned Aerial Vehicles" with publication number "CN211663434U". This device includes a drone body with four wings evenly distributed on the sidewall of the drone body. Each wing is equipped with a blade protection structure. A landing protection structure is installed at the lower end of the drone body. This utility model has a simple and reasonable structure. The protective cover protects the drone's rotor. The first spring, connecting rod, and connecting block provide a buffer when the protective cover collides with an object. The rotation of the rollers changes the impact direction of the drone body, preventing continuous impact on the same location of the protective cover and improving its service life. The landing protection structure provides a buffer when the drone lands, preventing excessive force during landing and damage to the drone body surface.
[0004] However, if traditional protective structures (such as integrated fuselage and fixed anti-collision frames) are damaged in a collision, they often need to be replaced as a whole or repaired with the help of professional tools or personnel. Users find it difficult to handle these issues themselves, resulting in high repair costs and long repair cycles. Utility Model Content
[0005] The purpose of this utility model is to provide a collision protection structure for drones, so as to solve the problem mentioned in the background art that if the traditional protection structure is damaged in a collision, it requires professional tools or personnel to repair it, which makes it difficult for users to handle it themselves.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision protection structure for unmanned aerial vehicles (UAVs), including a control component and a takeoff frame fixedly connected to the four sides of the top surface of the control component. A receiving block is fixedly connected to the top surface of the control component. Anti-collision structures are provided on the four sides of the top surface of the takeoff frame, which can protect the fan blades when the takeoff frame takes off and is easy to disassemble. A shock-absorbing structure is provided at the bottom of the takeoff frame away from the anti-collision structure, which can absorb shock when the takeoff frame lands and is also easy to disassemble.
[0007] Preferably, the anti-collision structure includes a protective ring, a mounting groove, and a protective net. Multiple protective rings are disposed on the top surface of the takeoff frame around the fan blade. Multiple mounting grooves are formed inside the protective rings. Multiple protective nets are fixedly connected to the interior of the multiple mounting grooves.
[0008] Preferably, the multiple protective nets are located at the top of the multiple fan blades.
[0009] Preferably, the anti-collision structure further includes mounting blocks and threaded blocks. The mounting blocks are fixedly connected to one side of the surface of the multiple protective rings, and the mounting blocks are located on the four sides of the top surface of the takeoff frame. The threaded blocks are threadedly connected to the interior of the mounting blocks.
[0010] Preferably, the bottom ends of the plurality of threaded blocks extend through to the top surface of the takeoff frame and are connected to the internal threads of the takeoff frame.
[0011] Preferably, the shock absorption structure includes fixed cavities and sliding plates, with multiple fixed cavities being opened inside the takeoff frame, and multiple sliding plates being slidably connected to the opposite surfaces on both sides of the inner wall of the fixed cavity.
[0012] Preferably, the shock absorption structure further includes sliding rods and springs. One side of each sliding rod is fixedly connected to the interior of the sliding plate, and one end of each sliding rod extends through the interior of the takeoff frame to the outside. Each spring is fixedly connected to the opposite side of the sliding plate and the fixed cavity.
[0013] Preferably, the shock-absorbing structure further includes plug-in blocks and shock-absorbing rubber blocks. The top ends of the multiple plug-in blocks extend through into the interior of the fixed cavity, and the interior of the multiple plug-in blocks is slidably connected to one end of multiple sliding rods. The multiple shock-absorbing rubber blocks are fixedly connected to the bottom surface of the multiple plug-in blocks.
[0014] The technical effects and advantages of this utility model are as follows: This utility model directly places the protective ring around the fan blade and positions the mounting block on the top surface of the takeoff frame. Then, the mounting block is stably installed on the top surface of the takeoff frame using threaded blocks, so that the protective ring fits around the fan blade. At the same time, the protective net isolates debris, and the rubber shock-absorbing block at the bottom absorbs shock during landing. It also has a disassembly function, allowing the device to be modularly designed, with the anti-collision structure and shock-absorbing structure separated into independent components. After a collision, only the damaged parts need to be replaced individually, without the need for returning to the factory or overall repair. This allows the device to be easily disassembled even by non-professionals, thereby improving the device's performance. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0021] Example 1
[0022] like Figures 1 to 4 As shown, a collision protection structure for a drone in the first aspect of this utility model includes a control component 1 and a takeoff frame 2 fixedly connected to the four sides of the top surface of the control component 1. A receiving block 3 is fixedly connected to the top surface of the control component 1. Anti-collision structures 4 are provided on the four sides of the top surface of the takeoff frame 2, which can protect the fan blades when the takeoff frame 2 takes off and is easy to disassemble. A shock-absorbing structure 5 is provided at the bottom of the takeoff frame 2 away from the anti-collision structure 4, which can absorb shock when the takeoff frame 2 lands and is also easy to disassemble.
[0023] The technical effects achieved by the above embodiments are as follows: This utility model directly places the protective ring 401 around the fan blade and positions the mounting block 404 on the top surface of the takeoff frame 2. Then, the mounting block 404 is stably installed on the top surface of the takeoff frame 2 by the threaded block 405, so that the protective ring 401 is fitted around the fan blade. At the same time, the protective net 403 isolates debris. During landing, the shock-absorbing rubber block 506 at the bottom is used for shock absorption. It also has a disassembly effect, so that the device can be modularly designed, and the anti-collision structure 4 and the shock-absorbing structure 5 can be separated into independent components. After a collision, only the damaged parts need to be replaced individually, without returning to the factory or overall repair. This allows the device to be flexibly disassembled even in front of non-professionals, thereby improving the device's performance.
[0024] Example 2
[0025] like Figure 1 and Figure 2 As shown, a drone collision protection structure includes all the contents of Embodiment 1. In addition, the anti-collision structure 4 includes a protective ring 401, a mounting groove 402, and a protective net 403. Multiple protective rings 401 are provided on the top surface of the takeoff frame 2 around the fan blades. Multiple mounting grooves 402 are opened inside the protective rings 401. Multiple protective nets 403 are fixedly connected to the inside of the multiple mounting grooves 402. Multiple protective nets 403 are located on the top of multiple fan blades. The anti-collision structure 4 also includes mounting blocks 404 and threaded blocks 405. Multiple mounting blocks 404 are fixedly connected to one side of the surface of multiple protective rings 401 and are located on the four sides of the top surface of the takeoff frame 2. Multiple threaded blocks 405 are threadedly connected to the inside of multiple mounting blocks 404. The bottom ends of multiple threaded blocks 405 extend through to the top surface of the takeoff frame 2 and are threaded inside the takeoff frame 2.
[0026] The technical effects achieved by the above embodiments are as follows: When using this utility model, the protective ring 401 is placed directly around the fan blade, and the mounting block 404 is located on the top surface of the takeoff frame 2. Then, the mounting block 404 is stably installed on the top surface of the takeoff frame 2 by the threaded block 405, so that the protective ring 401 is fitted around the fan blade, while the protective net 403 isolates debris. When disassembling, simply rotate the threaded block 405 again to disassemble the anti-collision structure 4.
[0027] Example 3
[0028] like Figure 1 , Figure 3 and Figure 4 As shown, a drone collision protection structure includes all the contents of Embodiment 2. In addition, the shock-absorbing structure 5 includes a fixed cavity 501 and a sliding plate 502. Multiple fixed cavities 501 are opened inside the takeoff frame 2. Multiple sliding plates 502 are slidably connected to the opposite sides of the inner wall of the fixed cavity 501. The shock-absorbing structure 5 also includes a sliding rod 503 and a spring 504. One side of the wall of multiple sliding rods 503 is fixedly connected to the inside of the sliding plate 502, and one end of each sliding rod 503 extends through the inside of the takeoff frame 2 to the outside. Multiple springs 504 are fixedly connected to the opposite sides of the multiple sliding plates 502 and the fixed cavity 501. The shock-absorbing structure 5 also includes a plug block 505 and a shock-absorbing rubber block 506. The top of multiple plug blocks 505 extends through the inside of the fixed cavity 501. At the same time, the inside of multiple plug blocks 505 is slidably connected to one end of multiple sliding rods 503. Multiple shock-absorbing rubber blocks 506 are fixedly connected to the bottom surface of multiple plug blocks 505.
[0029] The technical effect achieved by the above embodiment is as follows: When the device lands, the shock-absorbing rubber block 506 at the bottom can be used for shock absorption. When the shock-absorbing rubber block 506 needs to be replaced, simply pull the sliding rod 503 extending from one side, and the sliding rod 503 will drive the sliding plate 502 to move, thereby squeezing the spring 504, causing the other end of the sliding rod 503 to move out from the inside of the plug block 505, and the shock-absorbing structure 5 can be disassembled.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
