Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a UAV radar obstacle avoidance device. Background Technology

[0002] Unmanned aerial vehicle (UAV) obstacle avoidance devices typically refer to equipment that detects obstacles using sensors (such as radar and lidar) and combines data processing with the flight control system to achieve obstacle avoidance. They detect obstacles and calculate distances by emitting electromagnetic waves and receiving their reflected signals. Obstacle avoidance radar technology plays a crucial role in UAV obstacle avoidance, enabling UAVs to fly safely in complex environments. It mainly consists of a detection module, a data processing module, and a protection module.

[0003] In the current technology, the obstacle avoidance radar of drones is exposed on the outside of the body. During daily handling and transportation, there is a risk of hardware damage due to bumps and knocks. At present, the protective cover of the obstacle avoidance radar is mostly a fixed structure. Although it can provide basic protection, it will further increase air resistance. Moreover, the fixed protective cover is inconvenient to disassemble after being damaged by collision, making it difficult to replace quickly and delaying use. Utility Model Content

[0004] The purpose of this invention is to provide a drone radar obstacle avoidance device. By rotating the rotating shaft, the position of the protective cover can be changed so that it covers the outside of the radar for daily transportation and retrieval protection, or it can be stored in the groove to avoid increasing air resistance during flight. The overall structure is easy to disassemble and can be quickly replaced if damaged, so as not to delay daily work.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A drone radar obstacle avoidance device includes a radar fixedly installed on the top of the drone and a protective cover rotatably installed on the top of the drone. The protective cover is fixedly connected to a rotating shaft through symmetrically arranged rotating arms on the side walls, forming a rotating frame centered on the rotating shaft, covering the space outside the radar. The drone has a groove at the end opposite to the radar, and the protective cover has a fixing plate fixedly connected to the side wall opposite to the rotating arms.

[0007] When the protective cover is in the closed state, the fixing plate is screwed to the drone by bolts. When the protective cover is in the unfolded state, it rotates and embeds into the groove, and the fixing plate is screwed to the side wall of the groove by bolts. An elastic barrier mechanism is provided between the two rotating arms to fit and cover the opening area of ​​the protective cover.

[0008] The top of the drone is symmetrically fixedly connected with a C-slot plate, the rotating shaft is movably fitted with the C-slot plate, and baffles are fixedly connected to both ends of the rotating shaft to limit the axial displacement of the rotating shaft when it rotates.

[0009] A limit bolt is screwed to the top of the C-slot plate, and its end abuts against the side wall of the rotating shaft. A buffer pad is fixedly connected to the inner wall of the protective cover.

[0010] The elastic barrier mechanism includes a slide rod slidably mounted between the two rotating arms, and the slide rod is elastically connected to the rotating shaft through a spring post on the side wall.

[0011] The sliding rod is fixedly connected to a curtain on the side opposite to the spring column. The end of the curtain is fixedly connected to a screw rod via a connecting rod. An adjusting screw ring is screwed onto the outer wall of the end of the screw rod.

[0012] The top of the protective cover is fixedly connected to a C-slot retaining plate two. When the protective cover is in a closed state, the screw is movably engaged with the C-slot retaining plate two.

[0013] The bottom end of the protective cover is symmetrically provided with slot 1 and slot 2. When the protective cover is in the unfolded state, slot 1 and slot 2 are respectively engaged with the connecting rod and screw.

[0014] The technical advantages achieved by this utility model are as follows: the position of the protective cover can be changed by rotating the rotating shaft, so that it can cover the outside of the radar for daily transportation and access protection, or be put into the groove to avoid increasing air resistance during flight. Moreover, the overall structure is easy to disassemble and can be quickly replaced after damage, so as not to delay daily work. Attached Figure Description

[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 Figures 1-3 , Figure 6 As shown, a drone radar obstacle avoidance device includes a radar 101 fixedly installed on the top of the drone 1, and a protective cover 2 rotatably mounted on the top of the drone 1. The protective cover 2 is fixedly connected to a rotating shaft 206 via symmetrically arranged rotating arms 205 on its side walls, forming a rotating frame centered on the rotating shaft 206, covering the space outside the radar 101. C-slot plates 103 are symmetrically fixedly connected to the top of the drone 1. The rotating shaft 206 is movably engaged with the C-slot plates 103, and both ends of the rotating shaft 206 are fixedly connected to... A baffle 207 is provided to limit the axial displacement of the rotating shaft 206 when it rotates. A limit bolt 104 is screwed to the top of the C-groove plate 103, and its end abuts against the side wall of the rotating shaft 206. A buffer pad 204 is fixedly connected to the inner wall of the protective cover 2. A groove 102 is provided at the end of the UAV 1 opposite to the radar 101. A fixing plate 201 is fixedly connected to the side wall of the protective cover 2 opposite to the rotating arm 205. When the protective cover 2 is in the closed state, the fixing plate 201 is screwed to the UAV 1 by bolts 202.

[0025] According to the above structure, rotating the protective cover 2 around the rotating shaft 206 allows the protective cover 2 to cover the outside of the radar 101, preventing the radar 101 from being bumped. The buffer pad 204 fits snugly against the radar 101, buffering the impact force. After the bolt 202 passes through the fixing plate 201, it is rotated and screwed into the pre-set slot on the top of the UAV 1. One side of the protective cover 2 is fixed by the bolt 202, while the other side is fitted into the C-shaped slot of the C-slot clamping plate 103 via the rotating shaft 206, ensuring the position of the protective cover 2 is fixed. The baffle 207 is located at both ends of the rotating shaft 206 and... Located on the outside of the C-slot plate 103, if the rotating shaft 206 moves left or right, the baffle 207 will be blocked by the C-slot plate 103, restricting its movement. The rotation limit bolt 104 can have one end inserted into the C-shaped slot of the C-slot plate 103 to block the rotating shaft 206 and prevent it from detaching from the C-slot plate 103. Similarly, if the limit bolt 104 is removed from the C-slot plate 103 and the fixing plate 201 is not fixed, the protective cover 2, the rotating arm 205, the rotating shaft 206, etc. can be removed from the C-slot plate 103 together for replacement.

[0026] See attached document Figures 2-6 When the protective cover 2 is in the unfolded state, it rotates and embeds into the groove 102, and the fixing plate 201 is screwed to the side wall of the groove 102 by bolts 202. An elastic barrier mechanism is provided between the two rotating arms 205 to fit and cover the opening area of ​​the protective cover 2. The elastic barrier mechanism includes a slide rod 208 slidably installed between the two rotating arms 205, and the slide rod 208 is elastically connected to the rotating shaft 206 through a spring post 209 on the side wall. A curtain 210 is fixedly connected to the slide rod 208 on the side opposite to the spring post 209. The end of the curtain 210 is fixedly connected to a screw 212 via a connecting rod 211. An adjusting screw ring 213 is screwed onto the outer wall of the end of the screw 212. A C-groove retaining plate 203 is fixedly connected to the top of the protective cover 2. When the protective cover 2 is in the closed state, the screw 212 and the C-groove retaining plate 203 are movably engaged. A retaining groove 1 214 and a retaining groove 215 are symmetrically opened at one end of the bottom of the protective cover 2. When the protective cover 2 is in the unfolded state, the retaining groove 1 214 and the retaining groove 215 are movably engaged with the connecting rod 211 and the screw 212, respectively.

[0027] According to the above structure, when the UAV 1 needs to perform flight operations, the protective cover 2 is rotated to fit into the groove 102, and then bolted to the inner wall of the groove 102 by bolts 202 passing through the fixing plate 201. At this time, the opening area of ​​the protective cover 2 faces upward. To prevent dust and impurities from accumulating inside the protective cover 2 during flight operations, the curtain 210 is moved by pulling the connecting rod 211, and the sliding rod 208 slides axially along the rotating arm 205. The spring column 209 extends accordingly, and the screw 212 is inserted into the second slot 215. The adjusting screw ring 213 is located on one side of the second slot 215. Rotating the adjusting screw ring 213 moves the screw 212 for fine adjustment until the connecting rod 211 is embedded in the first slot 214. The position of the curtain 210 is fixed and covers the opening of the protective cover 2 for dust and dirt prevention. When the protective cover 2 rotates to cover the outside of the radar 101, the curtain 210 is engaged with the second slot 203 of the C slot through the screw 212. The adjusting screw ring 213 is located on one side of the second slot 203 of the C slot to prevent the curtain 210 from retracting and to temporarily fix it.

[0028] This utility model can change the position of the protective cover 2 by rotating the rotating shaft 206, so that it covers the outside of the radar 101 for daily transportation and access protection, or is put into the groove 102 to avoid increasing air resistance during flight. The overall structure is easy to disassemble and can be quickly replaced after damage, so as not to delay daily work.

[0029] The working principle of this utility model is as follows: The protective cover 2 is rotated around the rotating shaft 206, allowing it to cover the outside of the radar 101, preventing it from being bumped or knocked. The buffer pad 204 fits snugly against the radar 101, buffering the impact force. The bolt 202 passes through the fixing plate 201 and is then screwed into a pre-set slot on the top of the UAV 1. One side of the protective cover 2 is fixed by the bolt 202, while the other side is fitted into the C-shaped slot of the C-slot retaining plate 103 via the rotating shaft 206, ensuring the protective cover 2 is fixed in position. The baffle 20... 7 is located at both ends of the rotating shaft 206 and outside the C-slot retaining plate 103. If the rotating shaft 206 moves left or right, the baffle 207 will be blocked by the C-slot retaining plate 103, restricting its movement. The rotation limit bolt 104 can have one end inserted into the C-shaped slot of the C-slot retaining plate 103 to block the rotating shaft 206 and prevent it from detaching from the C-slot retaining plate 103. Similarly, if the limit bolt 104 is removed from the C-slot retaining plate 103 and the fixing plate 201 is not fixed, the protective cover 2, the rotating arm 205, and the rotating shaft 206 can be removed. 06 and other components are removed from slot C, plate 103 for replacement. When the UAV 1 needs to operate, the protective cover 2 is rotated to fit into the slot 102, and bolts 202 are passed through the fixing plate 201 and screwed into the inner wall of the slot 102. At this time, the opening area of ​​the protective cover 2 faces upward. To prevent dust and impurities from accumulating inside the protective cover 2 during operation, the curtain 210 is moved by pulling the connecting rod 211. The sliding rod 208 slides axially along the rotating arm 205, and the spring column 209 extends to insert the screw 212. The adjusting screw 213 is located on one side of the second slot 215. Rotating the adjusting screw 213 moves the screw 212 for fine adjustment until the connecting rod 211 is embedded in the first slot 214. The position of the curtain 210 is fixed and covers the opening of the protective cover 2 for dust and dirt prevention. When the protective cover 2 rotates to cover the outside of the radar 101, the curtain 210 is engaged with the second slot plate 203 of the C slot through the screw 212. The adjusting screw 213 is located on one side of the second slot plate 203 of the C slot to prevent the curtain 210 from retracting and to temporarily fix it.
