[0030] Reference Figure 1 - Figure 5 This utility model provides an automatic charging device for drones used in drone nests, including a mounting base 1, a power supply module 2, and a charging telescopic module 3. The charging telescopic module 3 includes a sliding seat 30, a buffer structure 31, a charging connector 32, and a connecting seat 33. The sliding seat 30 is slidably mounted on the mounting base 1 along a first horizontal direction and is slidably connected to a guide rail fixed on the mounting base 1. The connecting seat 33 is fixed to the front end of the sliding seat 30. A T-shaped groove 330 penetrating the front end of the connecting seat 33 is formed on its upper surface along the first horizontal direction. The direction perpendicular to the first horizontal direction is designated as a second horizontal direction. One end of the buffer structure 31 is connected to the mounting base 1, and the other end is connected to the sliding seat 30. The buffer structure 31 buffers the sliding of the sliding seat 30 in the first horizontal direction, allowing the movable seat 321 to move elastically in the first horizontal direction.

[0031] The charging connector 32 includes a movable base 321 and a charging terminal 322. The T-shaped groove 330 includes a mounting groove 3301 and a clearance groove 3303. One end of the movable base 321 is placed in the mounting groove 3301, and the other end extends out from the clearance groove 3303 along a first horizontal direction. The movable base 321 is movable in both a vertical and a second horizontal direction. The charging terminal 322 is fixed to the movable base 321. One end of the charging terminal 322 passes through the front end face of the movable base 321 along the first horizontal direction, and the other end passes through the rear end of the movable base 321 and is electrically connected to the power supply module 2 mounted on the mounting base 1. A wire-passing groove 3304 communicating with the mounting groove 3301 is provided on the rear end face of the movable base 321. The charging terminal 322 passes through the wire-passing groove 3304 along the first horizontal direction, exits the movable base 321, and is electrically connected to the power supply module 2.

[0032] In addition, a cover plate 34 is provided on the upper surface of the connecting seat 33. The cover plate 34 is fixed to the connecting seat 33 by screws. A first elastic element, which is a spring, is connected between the movable seat 321 and the cover plate 34. The two side walls of the movable seat 321 in the second horizontal direction are set as first connecting walls 3210, and the two side walls of the mounting groove 3301 in the second horizontal direction are set as second connecting walls 3302. A second elastic element, which is a spring, is connected between each first connecting wall 3210 and each second connecting wall 3302. The front end of the movable seat 321 is also provided with guide parts 35 on both sides in the second horizontal direction. These guide parts 35 are used to guide the battery assembly on the UAV into the space between the two guide parts 35. During the process of the guide parts 35 guiding the battery assembly of the UAV into the space between the two guide parts 35, the force exerted by the battery assembly on the guide parts 35 forces the movable seat 321 to automatically compensate for the deviation of the charging terminal 322 and the charging port on the battery assembly of the second elastic element in the vertical and second horizontal directions.

[0033] Of course, the central axis of the charging port on the drone in the first horizontal direction is theoretically coaxial with the central axis of the end of the charging terminal 322 used to insert the charging port of the drone in the first horizontal direction.

[0034] In summary, it can be understood that when the automatic charging device for drone nests of this utility model is in use, the power supply module 2 supplies power to the charging terminal 322 of the charging connector 32. Since one end of the movable seat 321 is placed inside the T-shaped groove 330 of the connecting seat 33, and the other end extends out of the T-shaped groove 330 of the connecting seat 33 along the first horizontal direction, and the movable seat 321 can move in the vertical and second horizontal directions, the first elastic element (not shown) connecting the movable seat 321 and the cover plate 34, and the second elastic element (not shown) connecting each first connecting wall 3210 on the movable seat 321 and each second connecting wall 3302 in the mounting groove 3301, allow the movable seat 321 to move elastically in the vertical and second horizontal directions. Furthermore, since the movable seat 321 is fixed on the sliding seat 30, the sliding seat... The sliding of the drone in the first horizontal direction is buffered by the buffer structure 31, thus allowing the movable seat 321 to move elastically in the vertical, first horizontal, and second horizontal directions. When the drone enters the space between the two guide sections 35 at the front end of the movable seat 321 along the first direction, the buffer structure 31 is elastically compressed. The force exerted by the drone on the guide section 35 forces the movable seat 321 to automatically compensate for the deviation between the charging terminal 322 and the drone's charging port in the vertical and second horizontal directions. This allows the charging terminal 322 on the charging connector 32 to automatically align with the drone's charging port. Simultaneously, under the elastic force of the buffer structure 31, the movable seat 321 slides forward along the first horizontal direction, allowing the charging terminal 322 on the movable seat 321 to accurately insert into the drone's charging port for charging. Therefore, the automatic drone charging device for drone nests of this invention can automatically compensate for the deviation between the charging terminal 322 and the drone's charging port in the vertical and second horizontal directions, thereby enabling the charging terminal 322 to accurately insert into the drone's charging port and greatly improving the drone's charging efficiency.

[0035] In one embodiment, the guide portion 35 includes a guide body 351, which is integrally connected to the movable seat 321. One end face of the guide body 351 facing away from the sliding seat 30 is configured as an inclined guide surface 352. The two inclined guide surfaces 352 form a V-shape, which facilitates guiding the battery assembly on the drone into the space between the two guide bodies 351. Since the movable seat 321 can move elastically in both the first and second horizontal directions, when the two side walls of the battery assembly on the drone contact the two inclined guide surfaces 352 in the second horizontal direction, as the drone continues to move backward in the first direction, the two inclined guide surfaces 352 can automatically compensate for the deviation between the charging terminal 322 on the movable seat 321 and the charging port of the drone in the second horizontal direction.

[0036] Furthermore, the opposing sides of the two guide bodies 351 are designated as working surfaces 3511. Two fixing strips 5 are provided on the working surfaces 3511 of the guide bodies 351. The fixing strips 5 extend along the first horizontal direction, and the two fixing strips 5 on the guide bodies 351 are arranged vertically at intervals. The gap between the two fixing strips on the guide bodies 351 forms a guide groove 353. The port of the guide groove 353 facing away from the sliding seat 30 is designated as a guide opening 354. The guide opening 354 has an eight-shaped structure, which facilitates the sliding part on the UAV's battery assembly to enter the guide groove 353. Of course, the sliding parts on the opposite side walls of the UAV's battery assembly in the second horizontal direction are respectively adapted to the two guide grooves 353. When the sliding part on the UAV's battery assembly contacts the guide opening 354, since the movable seat 321 can move elastically in the vertical direction, as the UAV continues to move backward in the first direction, the guide opening 354 can automatically compensate for the vertical deviation between the charging terminal 322 on the movable seat 321 and the UAV's charging port.

[0037] It should be noted that the driving force for the drone's movement along the first direction comes from the driving force on the drone's nest used to drive the landing pad to extend and retract along the horizontal first direction, which will not be explained here. Since the drone is docked on the landing pad, the movement of the landing pad along the horizontal first direction is the movement of the drone in the horizontal first direction.

[0038] In one embodiment, the buffer structure 31 includes a first spring 311 and a second spring 312. One end of the first spring 311 is fixedly connected to the mounting base 1, and the other end is fixedly connected to the sliding seat 30. The first spring 311 extends along a first horizontal direction. One end of the second spring 312 is fixedly connected to the mounting base 1, and the other end is fixedly connected to the sliding seat 30. The second spring 312 and the first spring 311 are symmetrical about the central axis of the sliding seat 30 in the first horizontal direction. This buffer structure 31 is beneficial for buffering the sliding of the sliding seat 30 in the first horizontal direction.

[0039] In one embodiment, a proximity switch 4 electrically connected to the power supply module 2 is also provided on the sliding seat 30. The proximity switch 4 is used to identify whether there is a drone charging with the charging terminal 322, which is beneficial to know in real time whether there is a drone charging.

[0040] In one embodiment, the opposing side walls of the clearance groove 3303 in the second horizontal direction are set as arc-shaped walls 3306, and the movable seat 321 has waist-shaped grooves 3211 on its opposing side walls in the second horizontal direction. The waist-shaped grooves 3211 extend along the second horizontal direction, and the distance between the upper surface of the movable seat 321 and the cover plate 34 forms the space for the movable seat 321 to move vertically. The distance between the end face of the waist-shaped groove 3211 in the second horizontal direction and the arc-shaped wall 3306 forms the space for the movable seat 321 to move horizontally in the second horizontal direction. Specifically, one end of the movable seat 321 is placed inside the mounting groove 3301. The height of the upper surface of the movable seat 321 is less than the depth of the T-shaped groove 330. The rear end face of the movable seat 321 in the first horizontal direction slides and fits against the rear end face inside the mounting groove 3301. The wall surface of the waist-shaped groove 3211 on the movable seat 321 in the first horizontal direction slides and fits against the movable seat 321. A gap is reserved between the wall surface of the waist-shaped groove 3211 in the second horizontal direction and the arc-shaped wall surface. This allows the movable seat 321 to move in both the vertical and second horizontal directions. The first elastic element connecting the movable seat 321 and the cover plate 34 is mainly used for the reset of the movable seat 321 in the vertical direction. Similarly, the second elastic element is mainly used for the reset of the movable seat 321 in the second horizontal direction.

[0041] In one embodiment, the first elastic element is a first return spring. Two sets of first return springs are provided, symmetrical about the central axis of the movable seat 321 in the horizontal first direction. This facilitates the vertical reset of the movable seat 321. To facilitate the installation of the first elastic element, multiple first spring mounting holes 3212 are provided on the upper surface of the movable seat 321. Each first spring mounting hole 3212 corresponds to a first return spring. A vertically extending first spring guide post 3213 is provided within the first spring mounting hole 3212. One end of the first return spring is fitted onto the first spring guide post 3213, and the other end abuts against the bottom wall of the cover plate 34.

[0042] Similarly, the second elastic element is a second return spring. A second spring mounting hole 3214 is provided on the first connecting wall 3210. A second spring guide post 3215 coaxial with the second spring mounting hole 3214 is provided in the second spring mounting hole 3214. A third spring guide post 3305 is provided on the second connecting wall 3302. Each third spring guide post 3305 is coaxial with each second spring guide post 3215 and corresponds to it one by one. One end of each second return spring is sleeved on each third spring guide post 3305, and the other end of each second return spring is sleeved on each second spring guide post 3215. This facilitates the installation of the second elastic element.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
