Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a battery replacement platform for unmanned aerial vehicles. Background Art

[0002] In recent years, the application of drones and artificial intelligence technology in the construction industry has developed rapidly. Drones are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. It has many advantages, such as convenient application and strong timeliness. Drones can be used to take high-altitude photos of buildings to obtain the overall picture of the buildings and the surrounding environment. In the civilian field, drones are widely used in aerial photography, agricultural plant protection, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, etc.; in the military field, they can perform reconnaissance, intelligence collection, tracking, communication and other tasks, but the endurance of drones has become the biggest bottleneck hindering the development of drones. Although lithium-ion batteries are the best comprehensive batteries on the market, they still cannot fully meet the endurance requirements of drones. Therefore, the charging problem of drones must be considered during the use of drones.

[0003] For example, a take-off and landing platform for facilitating battery replacement of VR drones disclosed in a Chinese patent document (Announcement No.: CN221091290U) is provided. Although this patent sets two clamping plates and starts a motor to drive the two clamping plates to move toward each other, the drone between the two clamping plates is automatically clamped and the position is locked, thereby improving the stability of the drone when replacing the drone battery; correspondingly, the two clamping plates are driven by the motor to move in the opposite direction, so that when the drone needs to take off, the position lock of the drone can be released, thereby making the drone take-off faster and improving work efficiency. The drone motor is placed in the charging cavity through the power charging block, and the drone battery plug is plugged into the power charging block, thereby charging the replaced battery. By setting a supporting plate, after the battery is charged, the supporting plate moves to drive the drone battery plug to separate from the power charging block, and the upper part of the drone battery is exposed outside the charging compartment, which is convenient for taking it out and easy to use.

[0030] Working principle: Step 1, when the UAV lands above the platform body 1, the second servo motor 814 is started to drive the rotating shaft 815 to rotate clockwise, and the rotation of the rotating shaft 815 drives the driving gear 816 to rotate. The rotation of the driving gear 816 drives the protective plate 812 to move through the meshing rack 813, so that the protective plate 812 moves to the inside of the movable storage groove 810. At this time, the square opening 89 is in an open state, and the piston rod of the servo electric cylinder 2 is started to extend, thereby driving the placement table 4 to move upward through the lifting block 3, so that the placement table 4 moves to the bottom of the square opening 89 and then the movement of the piston rod of the servo electric cylinder 2 is stopped;

[0031] Step 2, take out the battery body 87 in the drone, place it on the placement table 4, and insert it into the drive block 88 for limiting, then start the piston rod of the servo electric cylinder 2 to retract, so that it drives the battery body 87 on the placement table 4 to move to the side of the charging chamber 86 where the battery body 87 is not placed, then start the first servo motor 6 to drive the screw rod 7 to rotate clockwise, the rotation of the screw rod 7 drives the moving block 81 to move through the limit of the stroke slot 5, the movement of the moving block 81 drives the plug block 83 to move through the extension plate 82, thereby driving the battery to be charged to move and insert it into the charging chamber 86 for charging, after the insertion is completed, the piston rod of the servo electric cylinder 2 retracts, so that it drives the plug block 83 to move downward and disengage from the drive block 88;

[0032] Step 3, when taking the battery, first start the first servo motor 6 to drive the screw rod 7 to rotate counterclockwise, thereby driving the insert block 83 to reset and move, then start the servo electric cylinder 2 piston rod to retract, drive the placement table 4 to move down to the bottom of the charging chamber 86 where the battery body 87 is stored, start the first servo motor 6 to drive the screw rod 7 to rotate clockwise, so that it drives the insert block 83 to move below the drive block 88, and then start the servo electric cylinder 2 piston rod to extend and insert it into the drive block 88 for limiting, and then start the first servo The servo motor 6 drives the screw rod 7 to rotate counterclockwise, so that the movement of the insertion block 83, through the cooperation of the driving block 88, pulls the battery body 87 out of the charging chamber 86 and moves it to the top of the placement table 4. Finally, the piston rod of the servo electric cylinder 2 is started to extend, so that it drives the placement table 4 to move up, making it convenient for the operator to take and replace the battery body 87.
