[0021] Referring to Figures 1 to 3According to the unmanned aerial vehicle landing platform, when the unmanned aerial vehicle needs to be landed and recovered, the driving device drives the lifting plate 21 to move downward, so that the plurality of supporting rods 22 move downward out of the plurality of avoiding gaps, at this time, the plurality of elastic strips 13 arranged in the left-right direction and spaced apart from each other form an elastic supporting surface, and when the unmanned aerial vehicle lands, the unmanned aerial vehicle can fall to the elastic supporting surface and be elastically supported by the plurality of elastic strips 13; when the unmanned aerial vehicle needs to be lifted, the driving device drives the lifting plate 21 to move upward, so that the plurality of supporting rods 22 pass through the plurality of avoiding gaps, at this time, the plurality of supporting rods 22 arranged in the left-right direction and spaced apart from each other form a rigid supporting surface, which can replace the elastic supporting surface to provide fixed support for the unmanned aerial vehicle, and after the unmanned aerial vehicle is stably supported, the stability during take-off of the unmanned aerial vehicle is ensured, so that the plurality of elastic strips 13 can be lifted to form the elastic supporting surface, elastic buffering and protection are provided for the unmanned aerial vehicle during recovery and landing of the unmanned aerial vehicle, and because the entire elastic supporting surface can provide elastic buffering, the accuracy required for positioning of the unmanned aerial vehicle is reduced, and the unmanned aerial vehicle landing platform is especially suitable for landing and recovery of the unmanned aerial vehicle when the unmanned aerial vehicle landing platform moves, in addition, the plurality of supporting rods can be lifted to form the fixed supporting surface, so that stable support can be provided for the unmanned aerial vehicle during take-off of the unmanned aerial vehicle.

[0022] In the unmanned aerial vehicle landing platform, when the unmanned aerial vehicle needs to be landed and recovered, the driving device drives the lifting plate 21 to move downward, so that the plurality of supporting rods 22 move downward out of the plurality of avoiding gaps, at this time, the plurality of elastic strips 13 arranged in the left-right direction and spaced apart from each other form an elastic supporting surface, and when the unmanned aerial vehicle lands, the unmanned aerial vehicle can fall to the elastic supporting surface and be elastically supported by the plurality of elastic strips 13; when the unmanned aerial vehicle needs to be lifted, the driving device drives the lifting plate 21 to move upward, so that the plurality of supporting rods 22 pass through the plurality of avoiding gaps, at this time, the plurality of supporting rods 22 arranged in the left-right direction and spaced apart from each other form a rigid supporting surface, which can replace the elastic supporting surface to provide fixed support for the unmanned aerial vehicle, and after the unmanned aerial vehicle is stably supported, the stability during take-off of the unmanned aerial vehicle is ensured, so that the plurality of elastic strips 13 can be lifted to form the elastic supporting surface, elastic buffering and protection are provided for the unmanned aerial vehicle during recovery and landing of the unmanned aerial vehicle, and because the entire elastic supporting surface can provide elastic buffering, the accuracy required for positioning of the unmanned aerial vehicle is reduced, and the unmanned aerial vehicle landing platform is especially suitable for landing and recovery of the unmanned aerial vehicle when the unmanned aerial vehicle landing platform moves, in addition, the plurality of supporting rods can be lifted to form the fixed supporting surface, so that stable support can be provided for the unmanned aerial vehicle during take-off of the unmanned aerial vehicle.

[0023] The application also comprises a protection mechanism, which comprises protection plates 3 arranged on the left and right sides of the bottom plate 11. When the lifting plate 21 moves upward, the two protection plates 3 can rotate upward in the direction of approaching each other. When the lifting plate 21 moves downward, the two protection plates 3 can rotate downward in the direction of moving away from each other. When the unmanned aerial vehicle needs to be recovered and landed, the lifting plate 21 moves downward, and the two protection plates 3 rotate downward in the direction of moving away from each other, at this time, the shielding of the two sides of the elastic support surface can be reduced, so that the unmanned aerial vehicle more smoothly enters the elastic support surface, and then the lifting plate 21 moves upward, and the two protection plates 3 rotate upward in the direction of approaching each other, providing shielding and protection on the left and right sides of the elastic support plate, and improving the anti-falling effect after the unmanned aerial vehicle is recovered.

[0024] The driving device can adopt an electric screw, a cylinder or a hydraulic cylinder, etc. to drive the lifting plate 21 linearly. In this embodiment, the driving device comprises a linear driving member 23 and a linkage assembly. The linkage assembly comprises a first linkage 241, a second linkage 242, a third linkage 243, a fourth linkage 244, an upper sliding block 245 and a lower sliding block 246. The upper sliding block 245 is slidably connected to the bottom side of the lifting plate 21 in the left-right direction. The lower sliding block 246 is slidably connected to the top side of the bottom plate 11 in the left-right direction. The linear driving member 23 is connected to the bottom plate 11. One end of the first linkage 241 is rotatably connected to the bottom side of the lifting plate 21. The other end of the first linkage 241 is rotatably connected to the lower sliding block 246. One end of the second linkage 242 is rotatably connected to the top side of the bottom plate 11. The other end of the second linkage 242 is rotatably connected to the upper sliding block 245. The middle part of the first linkage 241 is rotatably connected to the middle part of the second linkage 242. One end of the third linkage 243 is rotatably connected to the upper sliding block 245. The other end of the third linkage 243 is rotatably connected to the fourth linkage 244. One end of the fourth linkage 244 is rotatably connected to the lower sliding block 246. The linear driving member 23 is drivingly connected to any one of the lower sliding blocks 246. The linkage assembly is symmetrically arranged in the left-right direction. Two of the protective plates 3 are respectively connected to the fourth linkages 244. In actual application, the linear driving member 23 can adopt an electric screw, a cylinder or a hydraulic cylinder, etc. The first linkage 241, the second linkage 242, the third linkage 243 and the fourth linkage 244 form a four-link mechanism. The first linkage 241 forms an upper rotating fulcrum at the bottom side of the lifting plate 21. The second linkage 242 forms a lower rotating fulcrum at the top side of the bottom plate 11. When the linear driving member 23 drives any one of the lower sliding blocks 246 to slide, it drives the third linkage 243 and the fourth linkage 244 to unfold in the direction away from the upper rotating fulcrum and the lower rotating fulcrum, thereby driving the lifting plate 21 to descend. Meanwhile, the linkage assembly on the other side also unfolds in the direction away from the upper rotating fulcrum and the lower rotating fulcrum. Thus, the lifting plate 21 descends while driving the two protective plates 3 to rotate downward in the direction away from each other. Similarly, when the linear driving member 23 drives any one of the upper sliding blocks 245 to slide, it drives the third linkage 243 and the fourth linkage 244 to fold in the direction close to the upper rotating fulcrum and the lower rotating fulcrum, thereby driving the lifting plate 21 to ascend. Meanwhile, the linkage assembly on the other side also folds in the direction close to the upper rotating fulcrum and the lower rotating fulcrum. Thus, the lifting plate 21 ascends while driving the two protective plates 3 to rotate upward in the direction away from each other. The lifting plate 21 and the protective plates 3 share a driving force, which simplifies the overall structure and reduces the working energy consumption.

[0025] In order to improve the stability of the transmission, in the embodiment, the driving device is provided with at least two in the front-rear direction, and the transmission rod is connected between the two front-rear opposite lower sliding blocks 246. The linear driving part 23 is in transmission connection with the transmission rod, and the linear driving part 23 can drive the transmission rod to move left and right. When working, the linear driving part 23 drives the transmission rod to move left and right. At this time, the driving force of left and right movement is transmitted to the lower sliding blocks 246 in the plurality of driving devices through the transmission rod, and the driving force of rotation is provided to the plurality of positions of the guard plate 3 in the front-rear direction, and the driving force of up and down movement is provided to the plurality of positions of the lifting plate 21 in the front-rear direction, thereby improving the stability of the movement of the lifting plate 21 and the guard plate 3.

[0026] In some embodiments, the two guard plates 3 are respectively connected with the buffer pads 25 on the side close to each other. When the two guard plates 3 are rotated upward and close to each other to the end of the stroke, the two guard plates 3 can be located on the two supporting rods 22 on the left and right sides, and at this time, the buffer pads 25 can play the role of elastic buffering, reducing the impact force when the two guard plates 3 stop rotating.

[0027] The lifting plate 21 can be connected only by the first connecting rod 241 and the upper sliding block 245. The front and rear sides of the lifting plate 21 are respectively connected with the side sliding blocks, and the two side sliding blocks are respectively connected with the two fixed plates 12 in the up-down direction. The front and rear sides of the lifting plate 21 are respectively connected with the two fixed plates 12 through the two side sliding blocks, which can improve the stability of the movement of the lifting plate 21 and facilitate the accurate extension of the plurality of supporting rods 22 into the plurality of avoiding gaps.

[0028] The elastic strip 13 is easy to lose elasticity after long-term use. In order to facilitate the maintenance of the elastic strip 13, in the embodiment, the front and rear ends of the plurality of elastic strips 13 are respectively detachably connected to the two fixed plates 12. During maintenance, the corresponding elastic strip 13 can be installed and replaced according to the tightness of each elastic strip 13, and the operation is flexible and convenient.

[0029] As an embodiment in which the elastic strip 13 is detachably connected to the fixed plate 12, the front and rear ends of the elastic strip 13 are respectively connected with the connecting heads 14, and the two fixed plates 12 are respectively provided with the connecting holes at the positions opposite to the plurality of elastic strips 13. The plurality of connecting heads 14 are respectively connected with the plurality of connecting holes through threads. When it is necessary to install the elastic strip 13, the connecting heads 14 at the front and rear ends of the elastic strip 13 are connected with the connecting holes through threads, so that one end of the elastic strip 13 can be connected and fixed, and the installation of the elastic strip 13 is completed. During use, the degree of thread connection between the connecting head 14 and the connecting hole can be adjusted, so as to adjust the tension of the elastic strip 13, and the use is more convenient.

[0030] Further, the plurality of connecting heads 14 respectively pass through the connecting holes and are connected with nuts. When the connecting heads 14 are positioned by being screwed in the connecting holes, the nuts can be further screwed on the connecting heads 14, so that the nuts abut against the fixing plates 12, further limiting the positions of the connecting heads 14 in the connecting holes, and improving the reliability of the installation and positioning of the connecting heads 14 on the fixing plates 12.

[0031] As the second embodiment that the elastic strips 13 are detachably connected to the fixing plates 12, one end of the plurality of elastic strips 13 is connected to one of the fixing plates 12, and the other fixing plate 12 is slidingly connected with a counterweight plate in the up-down direction, and the other end of the plurality of elastic strips 13 passes through the other fixing plate 12 and is connected to the counterweight plate. At this time, one end of the elastic strip 13 is fixed to one fixing plate 12, and the other end is connected to the counterweight plate, and the elastic strip 13 is tensioned by the counterweight plate, so that even if the elastic strip 13 is loosened after long-term use, the counterweight plate gradually moves downward to tension the elastic strip 13, and the tensioned state of the elastic strip 13 is automatically maintained.

[0032] The above describes the preferred embodiments of the present application, but the present application is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
