Detailed implementation manners

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, as Figures 1 - 4 shown, a vehicle-mounted lifting platform for a mapping unmanned aerial vehicle includes an installation box 101. Two rotatable threaded rods 102 and two fixed sliding rods 103 are vertically arranged in the installation box 101. The two threaded rods 102 and the two sliding rods 103 are arranged in a rectangular distribution. The two sliding rods 103 are distributed at the diagonal positions of the rectangle. The threaded rod 102 penetrates through and is threadedly connected to the lifting plate 104. The lifting plate 104 is slidably connected to the sliding rod 103 through. The lower end of the threaded rod 102 is coaxially provided with a driven bevel gear 207. A driving mechanism for driving the driven bevel gear 207 to rotate is provided at the bottom of the installation box 101. The top of the installation box 101 is rotatably connected to a cover plate 301 through a hinge 302. A linkage assembly is provided between the cover plate 301 and the lifting plate 104. A connecting block 402 for connecting to the top of the vehicle is provided at the bottom of the installation box 101.

[0024] In this embodiment, the driving mechanism drives the driven bevel gear 207 to rotate. The driven bevel gear 207 drives the lifting plate 104 to slide up and down on the sliding rod 103. The lifting plate 104 drives the cover plate 301 to open and close through the linkage assembly. When the lifting plate 104 is in a non-use state, it is inside the installation box 101. The lifting plate 104 pulls the cover plate 301 through the linkage assembly, so that the cover plate 301 keeps covering the opening at the top of the installation box 101, preventing foreign objects from falling on the lifting plate 104. When the unmanned aerial vehicle needs to take off and land, the driving mechanism drives the lifting plate 104 to rise, so that the upper surface of the lifting plate 104 is higher than the upper surface of the lifting plate 104. At the same time, the lifting plate 104 drives the cover plate 301 to open through the linkage assembly, facilitating the takeoff and landing of the unmanned aerial vehicle.

[0025] In one embodiment, as Figure 2 and Figure 3As shown, the driving mechanism includes a driving motor 202 disposed on the inner bottom surface of the installation box 101. One end of a power output shaft 203 is connected to the power output end of the driving motor 202, and the other end of the power output shaft 203 is coaxially connected to a driving bevel gear 201. The driving bevel gear 201 drives a driven bevel gear 207 to rotate through a transmission structure. The driving motor 202 drives the driving bevel gear 201 to rotate through the power output shaft 203, and the driving bevel gear 201 drives the driven bevel gear 207 through the transmission structure.

[0026] In one embodiment, as Figure 2 and Figure 3 shown, the transmission structure includes two first transmission bevel gears 204 meshed with the driving bevel gear 201. One end of a transmission shaft 205 is coaxially connected to the first transmission bevel gear 204, and the other end of the transmission shaft 205 is coaxially connected to a second transmission bevel gear 206. The middle of the transmission shaft 205 rotatably penetrates through a bearing seat 208. The bearing seat 208 is disposed on the inner bottom surface of the installation box 101. The second transmission bevel gear 206 is meshed with the driven bevel gear 207. The driving bevel gear 201 drives the first transmission bevel gear 204 to rotate. The first transmission bevel gear 204 drives the transmission shaft 205 to rotate in the bearing seat 208. The transmission shaft 205 drives the second transmission bevel gear 206 to rotate. The second transmission bevel gear 206 drives the driven bevel gear 207 to rotate.

[0027] In one embodiment, as Figure 3 and Figure 4 shown, the linkage assembly includes an L-shaped lifting plate connecting seat 304 disposed in the middle of the right end of the lifting plate 104. One end of a connecting rod 306 is rotatably connected to the upper end of the lifting plate connecting seat 304, and the other end of the connecting rod 306 is rotatably connected to a cover plate connecting seat 305. The cover plate connecting seat 305 is disposed on the lower surface of the cover plate 301. When the lifting plate 104 ascends, the lifting plate connecting seat 304 pushes the cover plate 301 to rotate upward about the hinge 302 through the connecting rod 306.

[0028] In one embodiment, as Figure 1 shown, a stop strip 303 is disposed at the left end of the upper surface of the cover plate 301. The lower surface of the stop strip 303 contacts the upper surface of the top of the installation box 101. When the cover plate 301 covers the top opening of the installation box 101, the stop strip 303 on the cover plate 301 is placed on the installation box 101 to share part of the weight of the cover plate 301.

[0029] In one embodiment, as Figure 2 shown, the middle of the power output shaft 203 rotatably penetrates through the bearing seat 208. The bearing seat 208 is disposed on the inner bottom surface of the installation box 101 to improve the stability of the power output shaft 203 during rotation.

[0030] In one embodiment, asFigure 1 As shown, a flow deflector 401 is provided on the right side of the installation box 101 to reduce the wind resistance of the installation box 101.

[0031] In one embodiment, as Figure 2 shown, a rubber pad 105 is provided on the upper surface of the lifting plate 104, so that it is not easy for the drone to slide relative to the lifting plate 104, and it plays a buffering role when the drone lands.

[0032] The above embodiment discloses a vehicle-mounted lifting platform for a mapping drone. Among them, the drive motor 202 drives the drive bevel gear 201 to rotate through the power output shaft 203. The drive bevel gear 201 drives the first transmission bevel gear 204 to rotate. The first transmission bevel gear 204 drives the transmission shaft 205 to rotate in the bearing seat 208. The transmission shaft 205 drives the second transmission bevel gear 206 to rotate. The second transmission bevel gear 206 drives the driven bevel gear 207 to rotate. The driven bevel gear 207 drives the lifting plate 104 to slide up and down on the sliding rod 103. While the lifting plate 104 rises and falls, the lifting plate connecting seat 304 on the lifting plate 104 acts on the cover plate connecting seat 305 on the cover plate 301 through the connecting rod 306, driving the cover plate 301 to open and close, so as to realize that the cover plate 301 opens synchronously when the lifting plate 104 is in use, and the cover plate 301 closes synchronously when the lifting plate 104 is not in use.

[0033] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
