[0030] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0031] Please refer to Figures 1-4 The embodiments of this application provide a driving device, including a base 100, a first mounting plate 200, a second mounting plate 300, a drive motor 400, a sprocket 500, and a chain 600. The first mounting plate 200, the second mounting plate 300, and the drive motor 400 are all disposed on the base 100. The sprocket 500 is rotatably disposed on the first mounting plate 200. The drive motor 400 is coaxially connected to the sprocket 500. The first mounting plate 200 and the second mounting plate 300 are respectively provided with a first track 210 and a second track 310, which are connected to each other. The chain 600 cooperates with the sprocket 500, and the chain 600 is at least partially disposed within the first track 210 and the second track 310.

[0032] Two sets of components are arranged opposite each other: a first mounting plate 200, a second mounting plate 300, a drive motor 400, a sprocket 500, and a chain 600. The drive motor 400 is coaxially connected to one of the sprockets 500. The two sprockets 500 are connected to each other through a drive shaft. The two chains 600 are respectively engaged with the two sprockets 500. The portion of the chain 600 located within the first track 210 extends along the first track 210, and the portion of the chain 600 located within the second track 310 extends along the second track 310.

[0033] By providing a first track 210 and a second track 310 on the first mounting plate 200 and the second mounting plate 300 respectively, and by placing at least a portion of the chain 600 within the first track 210 and the second track 310, the running trajectory of the chain 600 is limited, thereby improving the stability of the chain 600's operation.

[0034] In this embodiment, the first track 210 includes a first horizontal track 211, a first circular arc track 212 and a first inclined track 213 arranged in sequence. The first inclined track 213 is inclined relative to the first horizontal track 211. The end of the first horizontal track 211 away from the first circular arc track 212 has an opening 214 for the chain 600 to extend out.

[0035] The first horizontal track 211 extends horizontally, and the first inclined track 213 is inclined downward relative to the first horizontal track 211. The chain 600 can run within the first horizontal track 211, the first arc track 212, and the first inclined track 213. One end of the chain 600 extends from the opening 214 at the end of the first horizontal track 211 away from the first arc track 212 and is used to connect the mobile platform of the UAV platform.

[0036] In this embodiment, the first mounting plate 200 includes a base plate 220, a first plate 230, and a second plate 240. The sprocket 500, the first plate 230, and the second plate 240 are all disposed on the same side of the base plate 220. The first plate 230 is provided with a first horizontal section 231 and a first inclined section 232. The second plate 240 is provided with a second horizontal section 241, an arc section 242, and a second inclined section 243. A first horizontal track 211 is formed between the first horizontal section 231 and the second horizontal section 241. A first arc track 212 is formed between the sprocket 500 and the arc section 242. A first inclined track 213 is formed between the first inclined section 232 and the second inclined section 243.

[0037] Both the first plate 230 and the second plate 240 are provided with at least two positioning holes and screw holes.

[0038] For example, the first plate 230 has two positioning holes. By setting positioning pins in the two positioning holes, the first plate 230 is first positioned, and then screws are set in the screw holes to fix the first plate 230 to the substrate 220. Similarly, the second plate 240 has two positioning holes. By setting positioning pins in the two positioning holes, the second plate 240 is first positioned, and then screws are set in the screw holes to fix the second plate 240 to the substrate 220.

[0039] By providing at least two positioning holes on the first plate 230 or the second plate 240, the first plate 230 or the second plate 240 can be positioned first and then fixed with screws, eliminating the need for additional tooling for positioning and improving assembly efficiency.

[0040] In this embodiment, the second track 310 includes a second arc track 311 and two second horizontal tracks 312 arranged sequentially. The second arc track 311 is arranged between the two second horizontal tracks 312, and one of the second horizontal tracks 312 is connected to the first inclined track 213.

[0041] The chain 600 can run within the second circular track 311 and two second horizontal tracks 312 arranged vertically. The lower second horizontal track 312 is connected to the first inclined track 213, thereby enabling the chain 600 to run between the first inclined track 213 and the second horizontal track 312.

[0042] In this embodiment, the second mounting plate 300 includes three spaced strip plates 320 and an end plate 330. A second horizontal track 312 is formed between two adjacent strip plates 320, and a second arc track 311 is formed between the end plate 330 and the middle strip plate 320.

[0043] Three strip plates 320 are arranged vertically, and the three strip plates 320 and the end plate 330 are all fixed to the base 100; one end of the middle strip plate 320 has an arc surface, and the arc surface and the inner side of the end plate 330 form a second arc track 311.

[0044] The end plate 330 is C-shaped, and its two ends are connected to two strip plates 320 located on both sides. The end of the strip plate 320 away from the end plate 330 is connected to the first mounting plate 200.

[0045] The two ends of the end plate 330 are connected to the two strip plates 320 located above and below. The ends of the strip plates 320 located above and in the middle that are away from the end plate 330 are connected to the first plate 230. The first plate 230 is also provided with an extension track that communicates with the second horizontal track 312. The strip plate 320 located below is connected to the second plate 240.

[0046] In this embodiment, one of the end plate 330 and the strip plate 320 located on one side is provided with a protrusion 321 and the other is provided with a recess 322, with the protrusion 321 and the recess 322 being in contact with each other; and / or, one of the strip plate 320 and the first mounting plate 200 is provided with a protrusion 321 and the other is provided with a recess 322, with the protrusion 321 and the recess 322 being in contact with each other.

[0047] For example, the end plate 330 has a recessed portion 322, and the two strip plates 320 located above and below each have a protrusion 321. The protrusion 321 and the recessed portion 322 are connected to each other, which serves to position the end plate 330 and the two strip plates 320. The first plate 230 has two mating ends, which respectively connect to the two strip plates 320 located above and in the middle. One of the two strip plates 320 has a protrusion 321, and the other strip plate 320 has a recessed portion 322. Correspondingly, the two mating ends of the first plate 230 have a recessed portion 322 and a protrusion 321, which serve to position the strip plates 320 and the first plate 230. The second plate 240 has a mating end with a recessed portion 322, and the lower strip plate 320 has a protrusion 321, which serves to position the strip plate 320 and the second plate 240.

[0048] In this embodiment, the thickness of the second mounting plate 300 is 6.5mm to 7.5mm, and the spacing between two opposite assembly pieces in the chain 600 is 7.8mm to 8.1mm.

[0049] It should be noted that the spacing between two opposite assembly pieces in the chain 600 needs to be slightly greater than the thickness of the second mounting plate 300. The end plate 330 and the three strip plates 320 have the same thickness, which is 6.5mm to 7.5mm. By limiting the spacing between two opposite assembly pieces in the chain 600 to 7.8mm to 8.1mm, the chain 600 is less likely to experience significant wear with the strip plates 320 or end plates 330 during operation, and the chain 600 can also operate more stably.

[0050] For example, the thickness of the second mounting plate 300 is 6.5 mm, 7.0 mm, or 7.5 mm, and correspondingly, the spacing between two opposite mounting pieces in the chain 600 is 7.8 mm, 8.0 mm, or 8.1 mm.

[0051] It should be noted that the base plate 220 needs to support the basic installation of the sprocket 500, which requires high strength. Considering the lightweight nature of the parts and the ease of processing, the base plate 220 is made of aluminum alloy. The first plate 230 and the second plate 240 are made of polyoxymethylene C1 series modified materials. Polyoxymethylene C1 series modified materials have high strength, good oil resistance and wear resistance, thereby reducing maintenance frequency and ensuring the life of the parts. The end plate 330 and the three strip plates 320 are all made of polyethylene terephthalate. The processing difficulty of polyethylene terephthalate is lower than that of polyoxymethylene C1 series modified materials. At the same time, polyethylene terephthalate does not require oil resistance and has good wear resistance.

[0052] An embodiment of this application also provides an unmanned aerial vehicle (UAV) platform, including a platform base, a movable platform, and the aforementioned drive device. The movable platform is movably mounted on the platform base, and a chain 600 is connected to the movable platform to drive the movable platform to move on the platform base.

[0053] The chain 600 is connected to the movable platform by one end of the opening 214 at the end of the first horizontal track 211 away from the first arc track 212. This allows the movable platform to move on the platform base when the chain 600 is running. When the movable platform carries a drone, it can smoothly transport the drone to the charging position for charging.

[0054] By selecting the materials for the first mounting plate 200 and the second mounting plate 300 and by designing the structure rationally, the entire drive unit operates smoothly, with low noise and a long lifespan, reducing maintenance frequency and improving the reliability and stability of the UAV's automated charging, thereby enhancing the reliability, stability, and lifespan of the UAV platform.

[0055] In summary, the embodiments of this application provide a driving device and a drone platform. The driving device includes a base 100, a first mounting plate 200, a second mounting plate 300, a drive motor 400, a sprocket 500, and a chain 600. By providing a first track 210 and a second track 310 on the first mounting plate 200 and the second mounting plate 300 respectively, and by placing at least a portion of the chain 600 within the first track 210 and the second track 310, the running trajectory of the chain 600 is limited, thereby improving the stability of the chain 600's operation.

[0056] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
