Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a foldable drone obstacle avoidance and navigation bracket. Background Technology

[0002] Drones play a vital role in aerial photography, logistics delivery, agricultural plant protection, surveying, and other fields. However, in complex environments such as urban complexes, forests, and indoor spaces, drones are prone to collisions with various obstacles, potentially leading to damage or accidents, resulting in personal injury or property loss. Therefore, obstacle avoidance and navigation mechanisms are generally needed to help drones perceive their surroundings, detect the distance, position, and shape of obstacles, and thus achieve autonomous obstacle avoidance. Existing technology includes a drone obstacle avoidance device comprising an upper protective bracket, a lower protective bracket, an impact ball, a rangefinder, a rotating motor, blades, and a motor. A buffer rod is connected above the impact ball, and the upper protective bracket is connected above the lower protective bracket, with a nut attached to the upper end of the lower protective bracket. This drone obstacle avoidance device, with its impact ball, cylinder, and buffer rod, effectively prevents the drone from colliding with obstacles or falling directly from the air when the rangefinder malfunctions or the battery is low, thus protecting the drone.

[0003] In the above process, the upper and lower protective brackets are connected by nuts, which requires disassembly and assembly each time they are used. The process is cumbersome and inconvenient. Therefore, we propose a foldable drone obstacle avoidance and navigation bracket. Utility Model Content

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0029] like Figure 1 As shown, the present invention proposes a foldable drone obstacle avoidance and navigation bracket, including a drone body 1, with support arms 2 fixedly connected to the four corners of the body 1, and a rangefinder head 5 fixedly installed at the bottom of the body 1. The rangefinder head 5 is provided with a sensor module 6 at the bottom, which is used to perceive the surrounding environment information of the drone in real time. Blades 4 are rotatably installed at the top of the end of each support arm 2, and a drive device 3 for driving the blades 4 to rotate is fixedly installed at the end of each support arm 2.

[0030] like Figure 2 , Figure 3 As shown, the main body 1 has foldable support structures 7 on both sides. Both sides of the main body 1 have several sets of electromagnets 15 for connecting the support structures 7. The connection between the electromagnets 15 and the main body 1 is made of engineering plastic. The control circuit for controlling the electromagnets 15 is electrically connected to the control system of the drone. The support structure 7 includes two sets of rotatably connected rods 8 and anti-collision rods 11. Both sides of the main body 1 have screws threadedly connected to the center. The center of each rod 8 has a screw hole for the screw to pass through. One end of the screw is connected to a fixing nut 9. When the support structure 7 is not needed for obstacle avoidance, the support structure 7 can be removed from the main body 1 by unscrewing the fixing nut 9, making it convenient to store the drone.

[0031] The rod body 8 has magnetic chucks 14 fixedly installed on the back side of both ends for connecting with electromagnets 15. When the electromagnets 15 are energized, they generate magnetism and attract each other with the magnetic chucks 14, thus fixing the rod body 8. Both ends of the rod body 8 are rotatably connected to support rods 10. Anti-collision rods 11 are respectively hinged to the ends of support rods 10. The rod body 8 and support rods 10 are connected by a rotating structure 13. The rotating structure 13 includes U-shaped parts 131 fixedly installed at both ends of the rod body 8. Connecting parts 133 fixedly connected to support rods 10 are rotatably installed in U-shaped parts 131.

[0032] In addition, anti-collision balls 12 are fixedly installed at the ends of the anti-collision bars 11 away from the bar body 8. The anti-collision bars 11 are telescopic bars with built-in hydraulic dampers. The anti-collision bars 11 and the support bars 10 are fixedly connected by a pivot and bolts. When a collision occurs, the anti-collision balls 12 are used to buffer the impact and reduce the instantaneous impact force. The anti-collision bars 11 are used to further absorb and disperse the impact energy, slow down the collision speed of the drone, and reduce the degree of damage to the drone.

[0033] like Figure 4 As shown, a handle 132 for fixing a connector 133 is slidably mounted on one side of the U-shaped member 131. At least two sets of fixing rods 134 are fixedly mounted on the side of the handle 132 near the U-shaped member 131. The end of the fixing rod 134 away from the handle 132 extends through the U-shaped member 131 into the connector 133. Multiple sets of springs 135 are fixedly connected between the handle 132 and the U-shaped member 131. The springs 135 are respectively sleeved on the outside of the fixing rods 134. Multiple round holes are opened in the connector 133 for the fixing rods 134 to pass through. Move the handle 132 so that the fixed rod 134 located in the connector 133 disengages from the connector 133, allowing the connector 133 to rotate within the U-shaped member 131. When the connector 133, which is fixedly connected to the support rod 10, is rotated to an appropriate angle, release the handle 132 so that the handle 132 returns to its original position under the action of the spring 135, and the fixed rod 134 is inserted into the corresponding round hole, thereby realizing the adjustment of the angle of the support rod 10, and thus realizing the angle adjustment of the anti-collision bar 11 and the anti-collision ball 12.

[0034] During operation, when preparing to use the drone, the rod 8 is rotated around the screw as an axis, so that the magnetic suction cups 14 on the back of both ends of the rod 8 and the electromagnets 15 come closer to each other. Then, the electromagnets 15 are energized to generate magnetism, attracting each other to the magnetic suction cups 14, thus fixing the rod 8. When the drone completes its flight mission and the support structure 7 needs to be folded up, the reverse is done. In addition, when the support structure 7 is not needed for obstacle avoidance, the support structure 7 can be removed from the main body 1 by unscrewing the fixing nut 9, making it convenient to store the drone.

[0035] Pulling handle 132 causes the fixed rod 134, located within connector 133, to disengage from connector 133, allowing connector 133 to rotate within U-shaped member 131. When connector 133, fixedly connected to support rod 10, is rotated to an appropriate angle, handle 132 is released, causing handle 132 to reset under the action of spring 135. The fixed rod 134 then inserts into the corresponding circular hole, thus adjusting the angle of support rod 10 and consequently adjusting the angles of anti-collision bar 11 and anti-collision ball 12.

[0036] During the drone's flight, the rangefinder 5 begins to operate. The sensor module 6 at the bottom of the rangefinder 5 is used to perceive the drone's surrounding environment in real time, detecting the distance, position, and shape of obstacles. When the sensor module 6 detects an obstacle ahead, it transmits the information to the drone's control system. Based on the received information, the control system controls the drone to adjust its flight direction and altitude to avoid the obstacle. If the drone fails to avoid the obstacle during flight and a collision occurs, the anti-collision ball 12 first acts as a buffer upon contact with the obstacle, reducing the instantaneous impact force. Then, the hydraulic damper inside the anti-collision bar 11 begins to work, further absorbing and dispersing the impact energy, slowing down the drone's collision speed, and reducing the degree of damage to the drone. Since the anti-collision bar 11 and the support rod 10 are fixedly connected by a pivot and bolts, if the anti-collision bar 11 is damaged under a large impact force, it can be easily disassembled and replaced in a timely manner to ensure the normal use of the drone afterwards.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
