Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle frames, and in particular relates to an anti-collision unmanned aerial vehicle frame. Background Art

[0002] Unmanned aerial vehicle, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by an on-board computer. UAVs can be divided into military and civilian use according to their application areas. In the military field, UAVs are divided into reconnaissance aircraft and target aircraft. In the civilian field, UAVs are currently used in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, wildlife observation and other fields, which has greatly expanded the use of UAVs themselves.

[0003] The prior art discloses an anti-collision UAV frame with patent announcement number CN213800204U. When in use, the above patent controls the rotation of the screw by a motor to drive the transmission block and the buffer frame to rotate until the buffer frame is parallel to the arm. The buffer frame is located on the outside of the UAV propeller to protect the propeller and prevent birds or other UAVs from colliding and causing damage. When the UAV lands, the motor rotates in the opposite direction to drive the buffer frame to rotate downward, so that the buffer frame contacts the ground first when the UAV lands, and acts as a landing gear to protect the UAV. However, the following deficiencies still exist in actual use: From a practical point of view, the anti-collision structure provided on the UAV frame can only protect the propeller of the UAV from being damaged when it collides with external objects, but cannot buffer the force of the collision. The protection of the UAV is still poor, and the anti-collision structure is mostly fixed. After multiple anti-collision, the anti-collision structure is easily damaged and difficult to replace, which affects the protection performance of the UAV frame.

[0004] Therefore, there is a need for an anti-collision UAV frame to solve the problems in the prior art that the force of the collision cannot be buffered, the protection of the UAV is still poor, and the anti-collision structure is difficult to replace when damaged. Utility Model Content

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a circular groove is symmetrically opened on one side of the vertical rod 503 away from the propeller 3, a T-shaped column 506 is slidably connected to the inside of the circular groove, and a first spring 505 is fixedly connected between the T-shaped column 506 and the circular groove.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the anti-collision plate 507 is fixedly connected to one end of the T-shaped column 506, and a rubber buffer layer 508 is installed on the other side of the anti-collision plate 507, and the anti-collision plate 507 and the rubber buffer layer 508 are arranged in sections;

[0027] By setting the rubber buffer layer 508, when the drone is hit, the collision acts first on the rubber buffer layer 508, and the rubber material undergoes elastic deformation, thereby alleviating part of the impact force and improving the buffering effect of the frame.

[0028] According to the above working process, it can be known that: through the protective mechanism 5, when subjected to external impact, the collision first acts on the rubber buffer layer 508, the rubber material undergoes elastic deformation, and partially reduces the impact force, and then transmits it to the first spring 505, the first spring 505 undergoes elastic deformation, and continues to absorb the impact force, thereby improving the buffering effect of the device and improving the protection of the frame to the propeller 3.

[0029] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the disassembly and assembly mechanism 6 is composed of a second spring 602, a positioning block 603, a push block 606, a baffle 607 and a third spring 608, and grooves 601 are symmetrically opened on the upper and lower sides of one end of the connecting rod 501, the positioning block 603 is slidably connected to the inside of the groove 601, and the second spring 602 is fixedly connected between the positioning block 603 and the bottom surface of the groove 601.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that a slide groove 604 is provided at one end of the bottom rod 502, and the slide groove 604 is adapted to the height of the connecting rod 501, and positioning grooves 605 are symmetrically provided on the upper and lower surfaces of the slide groove 604, and the shape of the positioning groove 605 is adapted to the positioning block 603;

[0031] The positioning block 603 is inserted into the positioning groove 605 to fix the connection between the connecting rod 501 and the bottom rod 502, thereby ensuring the stability of the connection.

[0032] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth to explain in detail that the push block 606 is slidably connected to the inside of the positioning groove 605, the baffle 607 is fixedly connected to the end of the push block 606 away from the slide groove 604, the third spring 608 is fixedly connected between the baffle 607 and the outer wall of the bottom rod 502, and the third spring 608 is sleeved on the outside of the push block 606;

[0033] By providing the third spring 608 , after the push block 606 pushes the positioning block 603 , the push block 606 is driven to return to its original position, so as to facilitate the next use.

[0034] This solution has the following working process: when the drone is in use, the collision first acts on the rubber buffer layer 508, the rubber material undergoes elastic deformation, and part of the impact force is mitigated, and then the T-shaped column 506 is driven to move through the anti-collision plate 507, so that the first spring 505 undergoes elastic deformation and continues to absorb the impact force, thereby improving the buffering effect of the device and the protection of the frame to the propeller 3; and when the protective mechanism 5 is damaged after being hit for a long time, the upper and lower baffles 607 are pressed to drive the push block 606 to move, and the positioning block 603 is pushed, so that the positioning block 603 is received in the groove 601. Internally, the connection between the connecting rod 501 and the bottom rod 502 is released to facilitate the disassembly of the bottom rod 502, and then the repaired or new bottom rod 502 is replaced. The end of the connecting rod 501 moves inside the slide groove 604, and the positioning block 603 is first squeezed into the interior of the groove 601 to facilitate the end of the connecting rod 501 to slide inside the slide groove 604 until the positioning block 603 moves to the position of the positioning groove 605. Under the elastic action of the second spring 602, the positioning block 603 is driven to be stuck into the interior of the positioning groove 605, fixing the connection between the connecting rod 501 and the bottom rod 502 to ensure the stability of the connection.

[0035] In summary: through the protection mechanism 5, when it is subjected to external impact, the collision acts first on the rubber buffer layer 508, the rubber material undergoes elastic deformation, and reduces part of the impact force, and then transmits it to the first spring 505. The first spring 505 undergoes elastic deformation and continues to absorb the impact force, thereby improving the buffering effect of the device and improving the protection of the frame to the propeller 3; through the disassembly and assembly mechanism 6, after the protection mechanism 5 is damaged by external impact, the protection mechanism 5 can be disassembled and a new protection mechanism 5 can be installed to continue to maintain the excellent protection performance of the frame.
