Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a power supply component of an unmanned aerial vehicle. Background Art

[0002] Drones are now widely used in various fields because of their portability and ability to perform aerial photography, telemetry, transportation and other functions. In order to make drones easier to control, drones are generally lighter, but this also means that the battery power carried by drones is limited and they cannot be left empty for a long time, so the battery components need to be replaced frequently. In order to facilitate the replacement of drone battery components, battery components are usually installed by threading or snapping, but the snap-on structure requires a certain amount of slots to be left on the fuselage to facilitate the installation and removal of the battery components, but this affects the smoothness of the fuselage, increases the wind resistance of the flight, and has poor sealing, so it cannot be used on rainy days. Although the threaded structure can be tightly connected, multiple disassembly and assembly can cause damage to the threads, which will cause subsequent installation to become loose and cause poor power contact.

[0018] The mounting groove 5 is an L-shaped structure, with a mounting block 6 slidingly connected in the middle of the mounting groove 5. A friction plate is provided at the upper end of the mounting block 6. The mounting block 6 and the battery column 3 are fixedly connected. The mounting block 6 is installed along the mounting groove 5, and the battery column 3 is inserted into the battery mounting hole 2 and then moved vertically. When the mounting block 6 moves to the bottom of the mounting groove 5, the battery column 3 is rotated again. At this time, the mounting block reaches the horizontal part of the mounting groove 5. At this time, the lower end of the connector 12 is tightly attached to the top plate 8. Under the action of the reset spring 9, the friction plate at the upper end of the mounting block 6 and the inner wall at the upper end of the mounting groove 5 are tightly attached together, which can prevent the battery column 3 from moving and loosening after installation.

[0019] The limiting rod 11 and the plug interface 10 are both rectangular structures. The upper end opening of the plug interface 10 is an arc-shaped structure, which is convenient for the insertion of the limiting rod 11. Both ends of the limiting rod 11 pass through the plug interface 10. After the battery column 3 is installed, the limiting rod 11 is plugged into the plug interface 10, thereby limiting the connector 12. When the battery column 3 rotates, the connector 12 will not rotate.

[0020] The lower end of the battery column 3 abuts against the upper end of the blocking ring 7, the thickness of the left side of the blocking ring 7 is less than that of the right side, the sliding plate 15 is slidably connected to the right side of the blocking ring 7, the left inner wall of the sliding plate 15 is fixedly connected with an extrusion head 16, the corner of the extrusion head 16 is an arc-shaped structure, a connecting spring 17 is fixedly connected between the right end of the sliding plate 15 and the blocking ring 7, the extrusion piece 18 is a square structure, the right side of the extrusion piece 18 is a columnar structure, the sliding plate 15 passes through the middle of the extrusion piece 18, the extrusion piece 18 is an iron structure, and when the battery column 3 is installed, the extrusion piece 18 is facing the strong magnet block 14. The outer side wall of the sliding plate 15 is provided with a guide groove 19, and the side wall of the guide groove 19 is an inclined structure. The guide groove 19 is located at the extrusion piece 18. When the connector 12 is against the top plate 8, the strong magnet block 14 is facing the extrusion piece 18, thereby attracting the extrusion piece 18. When the extrusion piece 18 moves, it squeezes the guide groove 19, thereby pushing the sliding plate 15 to move. The extrusion head 16 at the front end of the sliding plate 15 squeezes the power connection piece 13, so that the power connection piece 13 is tightly against the connector 12 to avoid loosening, thereby ensuring the normal operation of the drone.

[0021] When the battery column 3 is installed, the mounting block 6 is installed along the mounting groove 5, and the mounting groove 5 is an L-shaped structure. When the mounting block 6 reaches the horizontal part of the mounting groove 5, the battery column 3 is rotated. At this time, the limit rod 11 is inserted into the plug interface 10 to limit the connector 12. The strong magnet block 14 at the side end of the connector 12 is facing the extrusion piece 18. The strong magnet block 14 attracts the extrusion piece 18 to move, and the extrusion piece 18 squeezes the guide groove 19, thereby driving the sliding plate 15 and the extrusion head 16 to squeeze the power connection piece 13, so that the power connection piece 13 is tightly against the connector 12.
