[0036] When inserting the battery, just push the battery directly into the battery shell 1. At this time, the battery pushes the slider 22 to slide to the side close to the locking rod 21, and the free end of the locking rod 21 slides and gets stuck in the guide groove 221. At this time, the locking hook 222 is engaged with the battery to fix the battery; when the battery needs to be taken out, the pressing needle 411 is inserted into the pressing hole 11. Due to the cooperation and extrusion of the pressing needle 411 and the inclined surface of the protrusion 223, the protrusion 223 slides to the side close to the locking rod 21, thereby driving the slider 22 to slide. The free end of the locking rod 21 slides in the guide groove 221 and releases the engaging state. The reset spring 23 drives the slider 22 to reset, and the slider 22 resets to push the battery out.

[0040] The inclined plate mechanism 5 includes a fixed shaft 51 and a slide plate 52. The fixed shaft 51 is fixedly installed in the parking area T. The slide plate 52 is rotatably installed on the fixed shaft 51. The slide plate 52 includes a dust shielding end 521 and a weighted end 522. The dust shielding end 521 is close to the entrance and exit K, and a dust shielding plate 521a is installed at the bottom. The weighted end 522 is far away from the entrance and exit K and is provided with a counterweight block.

[0041] The platform body 3 is provided with a slide 31 in the battery exchange area H. The slide 31 includes an inclined section 311 and a horizontal section 312. The inclined section 311 is close to the entrance and exit K, and the horizontal section 312 is at the same height as the bottom surface of the inner wall of the charging compartment 73 located at the bottom.

[0042] After the battery is pushed out, the battery is placed on the dust shielding end 521 of the slide plate 52 by the robotic arm. The dust shielding end 521 is deflected downward by the pressure of the battery, forming an inclined surface of the battery exchange area H, allowing the battery to slide into the battery exchange area H. Since the battery exchange area H is close to the entrance and exit K is an inclined section 311, the battery can slide a long distance inside the battery exchange area until it enters the horizontal section 312.

[0043] The driving mechanism 6 includes a motor 61, a one-way bearing 62, a first bevel gear 63 and a second bevel gear 64. The motor 61 is fixed inside the battery exchange area H.

One side of the rotating disk 72 is connected to the second bevel gear 64, and one side is equipped with a charging compartment 73, which corresponds to the second through slot 721. The first through slot 711 and the second through slot 721 are arranged to facilitate heat dissipation of the battery while cooperating with the ejection mechanism 10 to eject the battery.

[0045] The pushing mechanism 8 includes a driving wheel 81, a belt 82, a driven wheel 83 and a push plate 84. The driving wheel 81 is fixedly connected to the output shaft of the motor 61, and a belt 82 is sleeved on its outer side. The other side of the belt 82 is sleeved on the driven wheel 83. The height of the driven wheel 83 is higher than that of the driving wheel 81, so that the push plate 84 has a displacement in the up and down directions and will not hinder the sliding of the battery. The two sides of the push plate 84 are fixed to the belt 82 by fixing parts, and a groove 841 is provided on the side close to the charging compartment 73.

[0046] After the battery enters the battery exchange area H, the motor 61 starts, and the driving wheel 81 connected to the motor output shaft rotates, driving the driven wheel 83 to rotate, causing the belt 82 to rotate, and the push plate 84 connected to the belt 82 approaches the battery and pushes the battery into the charging compartment 73.

[0047] When the battery enters the charging compartment 73, the motor 61 reverses, causing the push plate 84 to move away from the battery and reset. At this time, due to the action of the one-way bearing 62, the output shaft of the motor 61 drives the first bevel gear 63 to rotate, and the two first bevel gears 63 drive the second bevel gear 64 to rotate 60°, thereby driving the turntable 72 to rotate 60°, and the charging compartment 73 located at the top rotates to the bottom.

[0048] The ejection mechanism 9 includes a telescopic rod 91 , one end of which is fixed, and the other end of which can pass through the first through slot 711 , the second through slot 721 and the charging compartment 73 .

[0049] When the position of the charging compartment 73 is changed, the fully charged battery is located at the bottom. The charged battery is rotated to the top, and the telescopic rod 91 is extended to pass through the first through slot 711, the second through slot 721 and the charging compartment 73, and the fully charged battery is pushed out, and the battery is put back on the drone by the robotic arm.

[0050] A maintenance mechanism 10 is also installed inside the charging mechanism 7. The maintenance mechanism 10 includes an airbag 101, an air pipe 102 and a nozzle 103. The airbag 101 is installed in the charging compartment 73. One end of the air pipe 102 is connected to the airbag 101, and the other end is connected to the nozzle 103. The nozzle 103 is installed on the platform body 3 and is located above the skateboard 52, and its jet outlet is inclined downward.

[0051] When the battery is pushed into the charging compartment 73 , the battery squeezes the airbag 101 , and the gas in the airbag 101 is transported to the nozzle 103 through the air pipe 102 , and is sprayed downward from the nozzle 103 to blow off the dust on the slide plate 52 .

[0052] In summary, when it is sensed that the drone has landed on the battery exchange platform, the clamping mechanism 4 is started, and the hydraulic cylinder 42 pushes the claw 41. The claws 41 approach each other and position the drone, and the pressing needle 411 extends into the pressing hole 11 to push the battery out; after the battery is pushed out, the battery is placed on the dust shielding end 521 of the slide plate 52 by the mechanical arm, and the dust shielding end 521 is deflected downward by the pressure of the battery, forming an inclined surface inclined to the battery exchange area H, so that the battery slides into the battery exchange area H. Since the battery exchange area H is close to the entrance and exit K at the inclined section 311, the battery can slide a long distance inside the battery exchange area until it enters the horizontal section 312; after the battery enters the battery exchange area H, the motor 61 is started, and the driving wheel 81 connected to the motor output shaft rotates, driving the driven wheel 83 to rotate, so that the belt 82 rotates, and the push plate 84 connected to the belt 82 approaches the battery and pushes the battery into the charging compartment 73; when the battery enters After the charging compartment 73 is rotated, the motor 61 reverses, so that the push plate 84 moves back to the direction away from the battery and resets. At this time, due to the action of the one-way bearing 62, the output shaft of the motor 61 drives the first bevel gear 63 to rotate, and the two first bevel gears 63 drive the second bevel gear 64 to rotate 60°, thereby driving the turntable 72 to rotate 60°, and the charging compartment 73 located at the top rotates to the bottom; when the position of the charging compartment 73 is changed, the fully charged battery is located at the bottom, and the battery to be charged rotates to the top. At this time, the telescopic rod 91 extends, passes through the first through groove 711, the second through groove 721 and the charging compartment 73, pushes out the fully charged battery, and the robot arm puts the battery back on the drone; when the battery is pushed into the charging compartment 73, the battery squeezes the airbag 101, and the gas in the airbag 101 is transported to the nozzle 103 by the air pipe 102, and is sprayed downward by the nozzle 103 to blow off the dust on the skateboard 52.
