[0026] The utility model will be further described below in conjunction with the accompanying drawings.

[0027] The utility model provides a drone nest. When charging a drone, the drone nest does not need to center the drone, thus avoiding the possibility of the drone being damaged during the centering process.

[0028] Figure 1 It is a structural schematic diagram of a charging device for a drone nest in one embodiment of the utility model; Figure 2 yes Figure 1 The enlarged structural diagram of A in the figure. Figure 1-2 As shown, an embodiment of the present application provides a charging device 1000 for a wireless charging device of a drone nest, and the charging device 1000 includes a nest shell 100, a parking platform 200, a wireless charging component 300, and a driving device 400. The nest shell 100 is provided with a receiving chamber. The parking platform 200 is arranged in the receiving chamber. The parking platform 200 includes a first surface and a second surface arranged opposite to each other in the thickness direction, and the first surface is used to park the drone. The wireless charging component 300 is arranged on the side of the parking platform 200 away from the first surface. The driving device 400 is installed in the receiving chamber, and the driving device 400 is connected to the wireless charging component 300. The driving device 400 drives the wireless charging component 300 to move so that the wireless charging component 300 is aligned with the drone in the thickness direction.

[0029] It should be noted that, in this embodiment, the thickness direction of the parking platform 200 is perpendicular to the horizontal direction, the UAV is parked on the first surface, i.e., the top surface, of the parking platform 200, and the wireless charging component 300 is arranged on the side of the parking platform 200 away from the first surface, i.e., below the parking platform 200. The driving device 400 can drive the wireless charging component 300 below the parking platform 200 to move, so that the wireless charging component 300 is aligned with the UAV above the parking platform 200 up and down, so that the wireless charging component 300 can wirelessly charge the UAV.

[0030] The driving device 400 may be a robot that is drivingly connected to the wireless charging component 300 , or may be a plurality of rope-driven components that are spaced apart along the circumference of the wireless charging component 300 , as long as the wireless charging component 300 can be moved.

[0031] According to the charging device 1000 of the drone nest according to the embodiment of the present application, when charging the drone parked on the first surface of the parking platform 200, the driving component drives the wireless charging component 300 disposed on the side away from the first surface to move, so that the wireless charging component 300 and the drone parked on the first surface of the parking platform 200 are aligned in the thickness direction of the parking platform 200, and then the wireless charging component 300 charges the drone. This avoids the charging device 1000 of the drone nest from performing a centering process when charging the drone parked on the parking platform 200, thereby avoiding the possibility of the drone being damaged during the centering process.

[0032] Furthermore, the parking platform 200 can be made of an acrylic plate to reduce the obstruction of the signal when the wireless charging component 300 is charging the drone parked on the first surface of the parking platform 200, thereby improving the stability of the wireless charging component 300 charging the drone.

[0033] like Figure 1-2 As shown, in some embodiments, the driving device 400 includes at least three driving mechanisms 410, and the at least three driving mechanisms 410 are distributed along the circumference of the wireless charging component 300. Each driving mechanism 410 includes a driving motor 411, a driving roller 412, and a driving wire 413. The driving motor 411 is installed on the second surface or on the machine nest shell 100. The driving motor 411 is drivingly connected to the driving roller 412. One end of the driving wire 413 is wound around the driving roller 412 and the other end is connected to the wireless charging component 300.

[0034] It should be noted that the number of drive mechanisms 410 is at least three. The drive wires 413 of each drive mechanism 410 are circumferentially spaced apart along the wireless charging assembly 300 and connected thereto. At least three drive wires 413 are connected to the wireless charging assembly 300. The drive motor 411 drives the roller to rotate to wind and unwind the drive wire 413, thereby pulling the wireless charging assembly 300 to move freely. It can be understood that the more the number of drive mechanisms 410 circumferentially spaced apart along the wireless charging assembly 300, the more precise the control of the movement direction of the wireless drive device 400. However, due to cost issues and the limited space of the accommodation chamber of the drone nest housing 100, the number of drive mechanisms 410 is preferably four. The four drive mechanisms 410 are evenly distributed around the wireless charging assembly 300, which satisfies the ability of the wireless charging assembly 300 to move in multiple directions while reducing the manufacturing cost of the charging device 1000 of the drone nest and reducing the volume of the drone nest.

[0035] In this embodiment, since there are at least three

[0036] drive mechanisms 410 circumferentially spaced apart along the wireless charging assembly 300, the drive motor 411 of the drive mechanism 410 drives the drive roller 412 to rotate, and the drive wire 413 will be tightened or loosened accordingly, so as to push or pull the wireless charging assembly 300 to be able to move flexibly in multiple directions to achieve precise alignment of the drone, ensuring the efficiency and stability of the wireless charging process of the drone and improving the charging efficiency. At the same time, due to the simple structure of the drive mechanism 410, once a failure or damage occurs, it can be quickly replaced or repaired, which is convenient for daily maintenance and overhaul.

[0037] As Figure 2 shown, in some embodiments, each drive mechanism 410 further includes a fixing plate 414. One end of the fixing plate 414 in the length direction is fixedly arranged at the bottom of the drone nest housing 100, and the drive roller 412 is rotatably installed on the fixing plate 414, and the length direction is parallel to the thickness direction.

[0038] In this embodiment, by installing the drive roller 412 on the fixing plate 414, a stable support platform is provided for the drive roller 412, enhancing the stability when the drive motor 411 drives the drive roller 412 to rotate. On the other hand, by installing the drive roller 412 at different installation positions along the length direction of the fixing plate 414, the distance between the drive roller 412 and the second surface of the parking platform 200 is adjusted, and then the vertical distance between the wireless charging assembly 300 and the drone is adjusted to improve the charging efficiency of the wireless charging assembly 300.

[0039] As Figure 2As shown, in some embodiments, the driving mechanism 410 further includes a tensioning assembly 415. The tensioning assembly 415 includes at least two tensioning rollers 415a. The at least two tensioning rollers 415a are both axially rotatably mounted on the fixing plate 414. The driving wire 413 is wound around the at least two tensioning rollers 415a and connected to the wireless charging assembly 300, and the axial direction is orthogonal to the length direction and parallel to the thickness direction.

[0040] In this embodiment, the tension roller 415a can, on the one hand, apply a certain tension to the driving wire 413 to keep it in a taut state, so as to reduce the slack and shaking of the driving wire 413 during the movement, thereby ensuring that the driving wire 413 can move smoothly along a predetermined path. On the other hand, the driving wire 413 is connected to the wireless charging component 300 after being wound around at least two tension rollers 415a of the tensioning assembly 415, so that when the driving motor 411 drives the driving roller 412 to rotate to pull the driving wire 413, the tension roller 415a increases the friction force on the driving wire 413, so that each driving wire 413 is constrained by the tensioning assembly 415, thereby improving the stability of the movement of the wireless charging component 300.

[0041] like Figure 2 As shown, in some embodiments, the tensioning assembly 415 further includes a mounting plate 415b. The mounting plate 415b is fixedly mounted on the fixing plate 414, and at least two tensioning rollers 415a are both axially rotatably mounted on the mounting plate 415b.

[0042] In this embodiment, the mounting plate 415b provides a solid support platform for the tensioning assembly 415, so that the tensioning roller 415a can be more firmly mounted on the fixed plate 414, reducing looseness or deviation caused by vibration or impact, ensuring that the tensioning roller 415a can rotate smoothly and guide the driving wire 413, thereby improving the stability of the movement of the wireless charging assembly 300.

[0043] like Figure 2 As shown, in some embodiments, the driving mechanism 410 further includes a steering assembly 416, and the steering assembly 416 includes a pulley seat 416a and a fixed pulley 416b. The pulley seat 416a is rotatably mounted on the second surface, the fixed pulley 416b is rotatably mounted on the pulley seat 416a, and the driving line 413 is wound around the fixed pulley 416b and connected to the wireless charging assembly 300.

[0044] It should be noted that the steering components 416 of each driving mechanism 410 are distributed on the second surface of the parking platform 200 at intervals along the circumference of the wireless charging component 300 .

[0045] The steering assembly 416 is disposed on the second surface of the parking platform 200. After the driving wire 413 is connected to the wireless charging assembly 300, the wireless charging assembly 300 can be closer to the second surface of the parking platform 200, reducing the distance between the wireless charging assembly 300 and the drone and improving the charging efficiency.

[0046] In this embodiment, the driving wire 413 wound around the fixed pulley 416b can change the pulling direction through the fixed pulley 416b. Since the pulley seat 416a mounting the fixed pulley 416b is rotatably mounted on the second surface of the parking platform 200, the orientation of the fixed pulley 416b can be changed, making the movement of the driving wire 413 smoother, improving the movement stability of the wireless charging assembly 300, increasing the movable range of the wireless charging assembly 300, reducing the movement blind area of the wireless charging assembly 300 below the parking platform 200, and thus increasing the rechargeable range of the drone.

[0047] As Figure 2 shown, in some embodiments, the steering assembly 416 further includes a fixed seat 416c. The pulley seat 416a is fixedly mounted on the fixed seat 416c. A first connecting member is provided on the fixed seat 416c, and a second connecting member is provided on the second surface. The first connecting member and the second connecting member are rotatably connected.

[0048] In this embodiment, the fixed seat 416c provides a stable mounting platform for the pulley seat 416a. The pulley seat 416a will not shift or shake relative to the fixed seat 416c during rotation, ensuring the stability and reliability of the pulley seat 416a during rotation. When it is necessary to adjust the direction of the driving wire 413, the first connecting member and the second connecting member on the fixed seat 416c rotate relative to each other to drive the pulley seat 416a and the fixed pulley 416b fixedly connected to the fixed seat 416c to rotate, thereby driving the orientation of the driving wire 413 wound around the fixed pulley 416b to change, ensuring the stability and reliability of the driving wire 413 during the steering process.

[0049] As Figure 2 shown, in some embodiments, one of the first connecting member and the second connecting member is a rotating shaft, and the other is a bushing that is in clearance fit with the rotating shaft and rotatably connected.

[0050] In this embodiment, the bushing is sleeved on the rotating shaft and rotatably connected to the rotating shaft. The second surface of the parking platform 200 and the fixed seat 416c are rotatably connected through the rotating shaft and the bushing in rotational fit, reducing the friction and wear of the steering assembly 416 during rotation, reducing the maintenance difficulty, and at the same time improving the efficiency and reliability of the entire steering assembly 416.

[0051] Furthermore, balls are provided between the rotating shaft and the bushing to reduce the wear between the rotating shaft and the bushing.

[0052] As Figure 2 shown, in some embodiments, the pulley seat 416a includes a pair of first plate members L1 arranged in pairs and a pair of second plate members L2 arranged in pairs. The pair of first plate members L1 are spaced apart along the first direction X. The pair of second plate members L2 are spaced apart along the second direction Y, and the pair of second plate members L2 are respectively connected between the pair of first plate members L1. The first plate member L1 of the pair of first plate members L1 close to the second surface is provided with a first connecting member. The second surface is provided with a second connecting member. The first direction X, the second direction Y, and the thickness direction are orthogonal to each other in pairs.

[0053] In this embodiment, the pair of first plate members L1 and the pair of second plate members L2 arranged in pairs enclose a rectangular frame, so that the pulley seat 416a can bear greater loads and impacts, is more structurally durable, and at the same time reduces the failure rate caused by deformation or damage. The fixed pulley 416b is arranged between the second plate members L2 through a connecting shaft, providing stable support for the fixed pulley 416b and ensuring the stability and balance of the pulley seat 416a in all directions.

[0054] As Figure 2 shown, in some embodiments, the steering assembly 416 further includes a limiting tube 416d. The limiting tube 416d is axially penetrated and fixedly connected to the first plate member L1 away from the second surface. The drive line 413 passes through the limiting tube 416d and is wound around the fixed pulley 416b.

[0055] In this embodiment, the drive line 413 passes through the limiting tube 416d and then is wound around the fixed pulley 416b and connected to the wireless charging assembly 300. The limiting tube 416d can play a role in restraining and limiting the drive line 413, reducing the vibration and shaking of the drive line 413 during winding and movement. At the same time, the limiting tube 416d provides a protective channel for the drive line 413 to prevent it from rubbing or colliding with other components, so as to extend the service life of the drive line 413 and reduce the system failure caused by the damage of the drive line 413.

[0056] The embodiment of the present application further provides a drone nest, including the charging device 1000 in any of the foregoing embodiments of the present application, having all the beneficial effects of the charging device 1000 in any of the above embodiments, which will not be elaborated here one by one.

[0057] Although the present utility model has been described with reference to the preferred embodiments, various modifications can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
