Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a UAV take-off and landing platform which is easy to carry and store. Background Art

[0002] Unmanned aerial vehicle, referred to as UAV, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by an on-board computer. With the development of technology, UAVs are increasingly used in real life, such as aerial photography, high-altitude spraying of fields, and power inspections. The light and flexible characteristics of UAVs are used to replace manual labor to complete more complex tasks. Therefore, the development of UAVs has improved people's work efficiency and reduced the risk of people's work.

[0003] The drone generates upward lift by the high-speed rotation of the wings on the top of the drone, but the drone needs a certain amount of time to accumulate power for take-off. During this time, if the ground where the drone is located is uneven, the drone will fail to take off. Therefore, existing drone take-offs are usually equipped with a take-off and landing platform, through which the drone can take off smoothly and land safely. However, the existing drone take-off and landing platform has a wide table top and generally does not have a folding and storage function, which makes it inconvenient to carry. Therefore, a drone take-off and landing platform that is easy to carry and store is needed to solve the existing shortcomings. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the present invention provides a technical solution: a UAV take-off and landing platform that is easy to carry and store, comprising a folding main board 1, folding sub-boards 2 are arranged at both ends of the folding main board 1, accommodating grooves 3 are arranged at the four corners of the folding main board 1, and a storage groove 4 is arranged at a corner of one side of the folding sub-board 2, and the accommodating groove 3 and the storage groove 4 are on opposite sides of each other, and a connecting mechanism 5 is movably connected at the connection between the accommodating groove 3 and the storage groove 4, the bottom end of the folding sub-board 2 is fixedly connected to a fixing plate 6, the inner side of the fixing plate 6 is hinged with a supporting foot 7, and the inner side of the fixing plate 6 is provided with a limiting mechanism 8.

[0026] When in use, first use the limiting mechanism 8 to release the restriction on the supporting feet 7, then store the supporting feet 7 to the inner side of the folding sub-panel 2, and then fold the two folding sub-panels 2 to the back side of the folding main board 1 through the connecting mechanism 5. At this time, the supporting feet 7 are located on the opposite sides of the folding main board 1 and the folding sub-panel 2, thereby realizing the folding and storage function of the lifting and landing platform.

[0027] like Figure 1and Figure 3 As shown, the connecting mechanism 5 includes a roller 501, a protective block 502, a connecting block 503 and a connecting rod 504, the outer ends of the connecting rod 504 are fixedly connected with the connecting blocks 503, the outer sides of the connecting blocks 503 are fixedly connected with the rollers 501, the outer sides of the rollers 501 are fixedly connected with the protective blocks 502, the diameter of the protective blocks 502 is larger than the diameter of the rollers 501, the interiors of the accommodating grooves 3 and the receiving grooves 4 are fixedly connected with slideways 9, the rollers 501 are slidably connected to the inner sides of the slideways 9, and the slideways 9 are located on the opposite sides of the protective blocks 502 and the connecting block 503, the opposite sides of the bottom ends of the accommodating grooves 3 and the receiving grooves 4 are provided with notches 10, the width of the notches 10 is consistent with the width of the connecting rod 504, the interiors of the accommodating grooves 3 and the receiving grooves 4 are fixedly connected with the limiting path 11, and the limiting path 11 is located on the inner side of the slideway 9, and the width of the limiting path 11 is consistent with the height of the connecting rod 504.

[0028] When in use, the folding sub-plate 2 is folded to the same horizontal plane as the folding main plate 1, and then the folding main plate 1 and the folding sub-plate 2 are brought close to each other, so that the rollers 501 at both ends of the connecting rod 504 roll on their respective slideways 9, and the connecting rod 504 slides laterally inside the limiting path 11. When the folding main plate 1 and the folding sub-plate 2 are completely fitted together, under the action of the limiting path 11 and the slideway 9, the folding sub-plate 2 cannot bend. When folding the folding sub-plate 2, the folding sub-plate 2 is pulled away from the folding main plate 1, and the connecting rod 504 is rotated to ninety degrees with the folding main plate 1 and the folding sub-plate 2. At this time, the connecting rod 504 is engaged with the inside of the notch 10.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the limiting mechanism 8 includes a limiting rod 801, a stop block 802, a return spring 803 and a pull ring 804. The middle section of the limiting rod 801 is movably connected to the inside of the fixed plate 6. The outer wall of the limiting rod 801 is sleeved with a stop block 802, and the outer wall of the limiting rod 801 is sleeved with a return spring 803. The front end of the return spring 803 is fixedly connected to the rear end of the stop block 802, and the rear end of the return spring 803 is fixedly connected to the inner side of the fixed plate 6. The pull ring 804 is fixedly connected to the rear end surface of the limiting rod 801. One side of the supporting foot 7 is fixedly connected to the limiting block 12, and the limiting block 12 is on the same side as the limiting rod 801. A limiting hole 13 is opened on one side of the limiting block 12, and the diameter of the limiting hole 13 is consistent with the diameter of the limiting rod 801.

[0030] When using the lifting and lowering platform, flip the supporting foot 7 outward and pull the pull ring 804. When the supporting foot 7 rotates to a vertical position, release the pull ring 804. Under the action of the reset spring 803, the front end of the limiting rod 801 engages with the inside of the limiting hole 13, thereby increasing the stability of the supporting foot 7 and preventing the supporting foot 7 from being automatically retracted when the lifting and lowering platform shakes.

[0031] Working principle: When in use, first fold the folding sub-plate 2 to the same level as the folding main plate 1, then bring the folding main plate 1 and the folding sub-plate 2 closer to each other, so that the rollers 501 at both ends of the connecting rod 504 roll on their respective slideways 9, and the connecting rod 504 slides laterally inside the limiting track 11. When the folding main plate 1 and the folding sub-plate 2 are completely fitted together, the folding sub-plate 2 cannot bend under the action of the limiting track 11 and the slideway 9. When folding, the folding sub-plate 2 is pulled away from the folding main plate 1 and And rotate the connecting rod 504 until it is ninety degrees with the folding main board 1 and the folding sub-board 2. At this time, the connecting rod 504 is engaged with the inside of the notch 10. In addition, when using the supporting foot 7, flip the supporting foot 7 outward and pull the pull ring 804. When the supporting foot 7 is rotated to a vertical position, release the pull ring 804. Under the action of the reset spring 803, the front end of the limit rod 801 is engaged with the inside of the limit hole 13, thereby increasing the stability of the supporting foot 7 and preventing the supporting foot 7 from being automatically retracted when the lifting and lowering platform shakes.

[0032] Intermediate state: by moving the folding main plate and the folding sub-plate closer to each other so that their opposite sides are close to each other, the two slides are driven closer to each other. At this time, the protective blocks are moved to the ends of the slides respectively, which is equivalent to the connecting rod being engaged at the connection between the folding main plate and the folding sub-plate, so that the folding main plate and the folding sub-plate are both in a horizontal state and cannot be folded under the action of the connecting rod.

[0033] It should be noted that, in this article, the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
