Description

Technical Field

[0001] The utility model relates to a leveling mechanism, in particular to a lifting and lowering platform support leveling mechanism. Background Art

[0002] Drones have many application scenarios in both military and civilian fields. In order to prevent them from rolling and tilting during takeoff and landing and reduce the risk of accidents during takeoff and landing, drones need a flat ground.

[0003] The patent with application number CN202322260019.7 discloses a UAV landing platform, including a landing plate, a wing plate arranged on the side of the landing plate, the landing plate is connected to the telescopic rod through a connecting assembly, a liquid tube is arranged on the upper surface of the landing plate, the liquid tube includes a transparent shell, the side of the transparent shell is marked with horizontal scale lines, and the transparent shell is filled with liquid; the wing plate connected to the side of the landing plate can be used to extend the surface of the landing plate, and the telescopic rod is used to prop up the landing plate. The telescopic rod can be used to adjust the height of the landing plate so that the landing plate is higher than the ground to adapt to various take-off terrains. By adjusting the length of each telescopic rod, the horizontality of the landing plate can be adjusted.

[0004] There is a problem in the leveling process. The landing platform generally tilts in multiple directions, and the structure that directly connects the telescopic rod to the landing platform does not have rotational freedom during adjustment. Even if a simple hinged structure is added, it only has freedom in one direction, and there will still be jamming during jacking and leveling. Utility Model Content

[0005] Based on the disadvantages of the prior art that the connection structure between the telescopic rod for leveling and the lifting and lowering platform has little freedom and is easily stuck during adjustment, the utility model provides a lifting and lowering platform support and leveling mechanism.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] The landing platform supports a leveling mechanism, including a jacking mechanism and a landing platform that is leveled by jacking up a number of jacking mechanisms. The jacking mechanism includes a driving mechanism and a transmission mechanism arranged at the output end of the driving mechanism. The transmission mechanism includes a jack and a universal joint. One end of the universal joint is fixedly connected to the jack, and the other end of the universal joint is fixed to the landing platform.

[0008] Preferably, the universal joint includes a mounting seat body, two cross shafts and two transmission shaft forks, the middle part of the mounting seat body has an installation space and the cross bars of the two cross shafts are rotatably connected to the mounting space of the mounting seat body, and the longitudinal bars of the two cross shafts are rotatably connected to the two transmission shaft forks respectively.

[0009] Preferably, a connecting end of one of the transmission shaft forks is provided with a connecting hole, and the connecting end of the other transmission shaft fork is a solid structure.

[0010] Preferably, one end of the push rod extends into the connecting hole and has an interference fit with the wall of the connecting hole.

[0011] Preferably, a plurality of slots are provided at the bottom of the landing platform, and the connection ends with solid structures at the top of the universal joint are inserted into the slots and have an interference fit with the side walls of the slots.

[0013] Preferably, a telescopic rod is provided at the output end of the telescopic cylinder and the telescopic motor, a socket is provided at the top of the telescopic rod, and the bottom of the top rod is inserted into the socket and has an interference fit with the side wall of the socket.

[0014] Preferably, steps are provided at the four ends of the cross shaft, and two groups of opposite mounting holes are provided on the mounting seat body. The side walls of the mounting holes are provided with embedding grooves and limiting clamps are embedded in the embedding grooves. After the two ends of the cross shaft are inserted into a group of opposite mounting holes, the two ends are limited by the clamps. At the same time, after installation, the step surface of the step is spaced from the inner end of the mounting hole.

[0015] Preferably, the landing platform is a rectangular structure, and four leveling mechanisms are provided and distributed in a rectangular array at the bottom of the landing platform.

[0016] Preferably, the box body is further included, which includes a bottom shell and a flip cover hinged on the bottom shell, the flip cover can be buckled on the bottom shell, the bottom shell has a concave cavity, the leveling mechanism is arranged on the bottom surface of the bottom shell, and the landing platform is located at the top of the concave cavity of the bottom shell and there is a gap between it and the cavity wall of the concave cavity.

[0017] Compared with the prior art, the advantages of the utility model are as follows: the utility model adds a push rod at the output end of the jacking mechanism and adds a universal joint with a double cross axis at the top of the push rod. When performing jacking and leveling, the universal joint can provide multi-directional freedom, thereby ensuring that multiple jacking mechanisms will not be stuck during jacking, reducing the influence between each other, and making the entire leveling process smoother.
