A rack 34 is meshed at the upper end of the gear 37. One end of the rack 34 is fixedly connected to a limiting block 36, and the other end of the rack 34 is fixedly connected to a sliding plate 32. Two suction cups 24 are fixedly connected to the outer side of the sliding plate 32, and sliding rods 30 are fixedly connected to the two ends of the sliding plate 32. The suction cups 24 correspond to the outer side of the battery inside the UAV 10 and are adsorbed and connected thereto. A release mechanism is provided inside the battery box 17 and the battery replacement box 25, and the release mechanism is used to release the battery 31, and the release mechanism includes a lifting plate 35 and a clamping head 33. The four corners of the lower end of the lifting plate 35 are fixedly connected with a stabilizing rod 40, and a spring 38 is sleeved on the rod body of the stabilizing rod 40, and the lifting rod 27 is fixedly connected on both sides of the lifting plate 35. The middle part of the clamping head 33 is fixedly connected by a connecting rod, and a rebound spring is sleeved on the rod body of the connecting rod, and the clamping head 33 is installed in a receiving groove opened in the side wall of the battery box 17, and the outer end of the clamping head 33 corresponds to the upper end of the lifting rod 27 and is slidably connected thereto, and the limiting rings 28 are fixedly connected to both sides of the battery box 17, and the limiting rings 28 correspond to the lifting rod 27 and are movably sleeved therewith.

[0016] In this setting, the present invention meets the usage requirements in different scenarios by adopting both wireless charging and battery replacement. At the same time, by miniaturizing the hangar as much as possible, it is convenient to relocate the hangar and increase its portability. In addition, a closed battery replacement design is adopted to prevent rainwater from splashing onto the terminals of the battery 31 when replacing the battery on rainy days, causing the battery 31 to short-circuit and unable to be used normally.

[0017] like Figures 1 to 8 As shown, in a specific embodiment, a slide groove 26 and a slideway 29 are provided on the side wall of the battery swap box 25, the slide groove 26 corresponds to the lower end of the lifting rod 27 and is slidably connected thereto, the slideway 29 corresponds to the slide rod 30 and is slidably connected thereto, and a plate groove 39 is provided on the inner bottom of the battery swap box 25, the plate groove 39 corresponds to the lifting plate 35 and is movably connected thereto, and four through holes are provided inside the plate groove 39, which correspond to the stabilizing rod 40 and are movably connected thereto.

[0018] In this arrangement, the removed battery will fall into the battery replacement box 25 and the lifting plate 35 will be pressed downward by gravity. The lifting plate 35 will pull the lifting rod 27 downward, causing the upper end of the lifting rod 27 to disengage from the clamping head 33. The clamping head 33 rebounds due to the loss of pressing force, causing the inner end of the clamping head 33 to disengage from the lower end of the fully charged battery 31. The battery 31 falls and overlaps with the original battery to increase its height. Then the motor 41 is started to push the battery 31 into the battery compartment of the drone 10 through the rack 34. When the suction cup 24 retracts, the battery 31 will be hindered by the seesaw squeezed and pried up by the lifting plate 35, causing the battery 31 to disengage from the suction cup.

[0019] like Figures 1 to 8 As shown, in a specific embodiment, a baffle 13 is fixedly connected to the bottom of the battery swap box 25 near the motor 41, and a rack ring 42 is fixedly connected to the inner side of the side wall of the battery swap box 25, and the inner ring of the rack ring 42 corresponds to the rack 34 and is slidably connected thereto.

[0022] In this configuration, the electric push rod 20 is started to fix the drone 10 through the upper and lower clamps, and then the motor 41 is started to move the rack 34 to one side of the drone through the gear 37.

[0023] like Figures 1 to 8 As shown, in a specific embodiment, an inner end of the storage box 3 is fixedly connected to the side wall of the hangar body 1, and an outer end of the storage box 3 is fixedly connected to the control box 5, an electric push-pull rod 18 is installed at the inner end of the control box 5, the other end of the electric push-pull rod 18 is fixedly connected to the battery box 17, and a push handle 4 is fixedly connected to the upper end of the control box 5.

[0024] In this configuration, the landing platform 11 will be affected by the weight of the drone itself, causing it to descend. During the descent of the landing platform 11, the pull rope 6 will pull the transmission wheel 9 to rotate, and the transmission wheel 9 will drive the reversal cover 2 to flip over, causing it to close, so that the interior is in a relatively closed state. When the landing platform 11 descends to the bottom, the electric push-pull rod 18 extends to push the battery exchange mechanism out.

[0025] like Figures 1 to 8 As shown, in the specific implementation manner, universal wheels 8 are fixedly installed at the four corners of the lower end of the hangar body 1, and a sliding hole 12 is opened on the side wall of the hangar body 1, and a slider 7 is slidably sleeved inside the sliding hole 12, and a pull rope 6 is fixedly connected to the outer end of the slider 7, and a landing platform 11 is fixedly connected to the inner end of the slider 7, and the upper surface of the landing platform 11 corresponds to the UAV.

[0026] In this configuration, the landing platform 11 will be affected by the weight of the drone itself, causing it to descend. During the descent of the landing platform 11, the pull rope 6 will pull the transmission wheel 9 to rotate, and the transmission wheel 9 will drive the reversal cover 2 to flip over, causing it to close.

[0027] like Figures 1 to 8As shown, in a specific embodiment, a transmission wheel 9 is installed at the four corners of the upper end of the hangar body 1, and the internal groove of the transmission wheel 9 corresponds to the upper end of the pull rope 6 and is wound and fixed therewith, and a shaft rod 16 is fixedly connected to the inner side of the transmission wheel 9, and the rod body of the shaft rod 16 passes through the ear plate fixedly connected to the upper end of the hangar body 1 and is movably sleeved therewith, and a torsion spring 15 is sleeved and installed on the rod body of the shaft rod 16, one end of the torsion spring 15 is fixedly connected to the inner side of the transmission wheel 9, and the other end is fixedly connected to the ear plate, and the other end of the shaft rod 16 is fixedly connected to the flip cover 2, and an indicator light 14 is fixedly installed on the inner surface of the flip cover 2.

[0028] In this setting, when the device is in standby mode, the reversing cover 2 is in an open state, and the indicator light 14 flashes alternately to guide the drone 10 and indicate the landing position. When the drone 10 lands on the surface of the landing platform 11, the propeller stops rotating.

[0029] The implementation principle of a drone charging and swapping motor library in this embodiment is as follows: The present invention adopts two methods, wireless charging and battery replacement, to meet the use requirements in different scenarios.

In addition, a closed battery replacement design is adopted to prevent rainwater from splashing onto the terminals of the battery 31 during battery replacement in rainy days, causing the battery 31 to short-circuit and fail to be used normally. When the device is in standby mode, the reversing cover 2 is in the open state, and the indicator light 14 flashes alternately to guide the UAV 10 and indicate the landing position. When the UAV 10 lands on the surface of the landing platform 11, the propeller stops rotating. At this time, the landing platform 11 will be affected by the weight of the UAV itself, causing it to descend. During the descent of the landing platform 11, the transmission wheel 9 will be pulled to rotate by the pull rope 6, and the transmission wheel 9 will drive the reversing cover 2 to flip, causing it to close, so that the interior is in a relatively closed state. When the landing platform 11 descends to the bottom, the electric push-pull rod 18 extends to push the power exchange mechanism out. At this time, the electric push rod 20 starts to fix the UAV 10 through the upper and lower clamps, and then starts the motor 41, and moves the rack 34 to one side of the UAV through the gear 37, and the end of the rack 34 The suction cup 24 will contact and adsorb the outer surface of the battery that needs to be replaced in the drone 10, and the motor will reverse to take out the battery in the battery compartment, and separate the battery and the suction cup 24 through the baffle 13, and the taken out battery will fall into the battery replacement box 25, and the lifting plate 35 will be pressed downward by gravity, and the lifting plate 35 will pull the lifting rod 27 downward, causing the upper end of the lifting rod 27 to separate from the clamping head 33, and the clamping head 33 will rebound due to the loss of pressing force, causing the inner end of the clamping head 33 to separate from the lower end of the fully charged battery 31, and the battery 31 falls and overlaps with the original battery to increase its height, and then the motor 41 is started to push the battery 31 into the battery compartment of the drone 10 through the rack 34, and when the suction cup 24 retracts, the battery 31 will be hindered by the seesaw squeezed and pried up by the lifting plate 35, so that the battery 31 is separated from the suction cup.
