DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 4 , a portable auxiliary take-off platform structure applicable to unmanned aerial vehicle (UAV) mapping provided by an embodiment of the present utility model. The portable auxiliary take-off platform structure applicable to UAV mapping includes a retractable cylinder 1, a fan-shaped assisting flight board 3, and an opening and closing assembly 4.

[0023] In an embodiment of the present utility model, please refer to Figures 1 to 4 , a coaxially arranged erection ring sleeve 2 is fixedly embedded at the top of the retractable cylinder 1, and a plurality of fan-shaped cavities 2a distributed in a ring shape and arranged radially are formed on the erection ring sleeve 2. A slidably connected fan-shaped assisting flight board 3 is installed in each of the fan-shaped cavities 2a, and the fan-shaped assisting flight boards 3 form a disc platform structure after being closed. An opening and closing assembly 4 for driving each fan-shaped assisting flight board 3 to slide in and out along the fan-shaped cavity 2a is installed on the retractable cylinder 1.

[0024] It should be noted that: by driving the fan-shaped assisting flight board 3 to slide out through the opening and closing assembly 4, the opening of the retractable cylinder 1 is exposed, facilitating the staff to take out the UAV from the retractable cylinder 1;

[0025] Subsequently, the opening and closing assembly 4 is used to drive the fan-shaped assisting flight board 3 to slide towards the center of the retractable cylinder 1 until a disc platform structure is formed after each fan-shaped assisting flight board 3 slides back. Then, the UAV is placed on the disc platform structure, and the UAV is started for take-off;

[0026] When the UAV returns to the disc platform structure after the mapping is completed, after the staff takes down the UAV, the opening and closing assembly 4 is used to drive the fan-shaped assisting flight board 3 to slide out so that the opening of the retractable cylinder 1 is exposed. Subsequently, after the UAV is placed in the retractable cylinder 1, the opening and closing assembly 4 is used to drive the fan-shaped assisting flight board 3 to close the retractable cylinder 1, thereby protecting the UAV in the retractable cylinder 1.

[0027] In an embodiment of the present utility model, please refer to Figures 1 to 4, a plurality of axially arranged mounting cavities 1a are formed in the outer cylinder wall of the winding and unwinding cylinder 1 in a circular distribution. The opening and closing assembly 4 includes a threaded rod 41 and a sliding rod 42. The threaded rod 41 is rotatably installed in any one of the mounting cavities 1a and is rotatably connected to the mounting cavity 1a, and the remaining mounting cavities 1a are fixedly installed with sliding rods 42. A threaded seat 43 is sleeved on the threaded rod 41 in a threaded connection. A sliding seat 44 is sleeved on each sliding rod 42 in a sliding connection. Opening and closing plates 45 are installed on both the threaded seat 43 and the sliding seat 44 in a rotational connection, and the other end of the opening and closing plate 45 is rotatably connected to the lower plate of the corresponding sector-shaped assisting flight plate 3. A servo motor 411 is embedded in the winding and unwinding cylinder 1, and the output end of the servo motor 411 is fixedly connected to one end of the threaded rod 41;

[0028] The opening and closing assembly 4 further includes a central coupling ring 46. The central coupling ring 46 is sleeved on the winding and unwinding cylinder 1 and is fixedly connected to the threaded seat 43 and the sliding seat 44 through brackets.

[0029] It should be noted that when the servo motor 411 is started to drive the threaded rod 41 to rotate, since the threaded seat 43 is fixedly connected to the sliding seats 44 on other sliding rods 42 through the central coupling ring 46, when the threaded seat 43 slides upward along the threaded rod 41, the opening and closing plates 45 on the threaded seat 43 and the sliding seats 44 can drive the connected sector-shaped assisting flight plates 3 to slide outward from the sector cavity 2a, so that the opening of the winding and unwinding cylinder 1 is exposed, facilitating the placement or removal of the drone;

[0030] When the servo motor 411 is started to drive the threaded rod 41 to reverse, when the threaded seat 43 slides downward along the threaded rod 41, the opening and closing plates 45 on the threaded seat 43 and the sliding seats 44 can drive the connected sector-shaped assisting flight plates 3 to slide inward from the sector cavity 2a, so that the sector-shaped assisting flight plates 3 form a disc platform structure, in order to close the opening of the winding and unwinding cylinder 1 or place the drone on the disc platform structure to prepare for takeoff;

[0031] Among them, when the sector-shaped assisting flight plates 3 form a disc platform structure, it is not necessary to completely close each sector-shaped assisting flight plate 3. The gap between the sector-shaped assisting flight plates 3 can be reasonably processed according to the size of the drone. The larger the distance between the relative sector-shaped assisting flight plates 3, the larger the area of the entire disc platform structure, thus facilitating the takeoff and parking of the drone more conveniently.

[0032] Furthermore, the radius of the sector-shaped assisting flight plate 3 is greater than the radius of the winding and unwinding cylinder 1, which is convenient for the disc platform area to be large enough for the drone to take off after the sector-shaped assisting flight plates 3 form a disc platform structure. The plate head of the opening and closing plate 45 connected to the sector-shaped assisting flight plate 3 is close to the outer edge of the sector-shaped assisting flight plate 3. Therefore, when the opening and closing assembly 4 drives the sector-shaped assisting flight plate 3 to slide back towards the center of the winding and unwinding cylinder 1, the opening and closing plate 45 will not have the risk of abutting against the erection ring sleeve 2.

[0033] In addition, a limiting strip 2a1 is fixedly installed on the inner top wall of the sector cavity 2a, and the limiting strip 2a1 is inserted into a sliding groove 3a opened at the top of the corresponding sector-assisted flying plate 3 and is slidably connected to the sliding groove 3a, thereby improving the stability of the sector-assisted flying plate 3 when sliding along the sector cavity 2a.

[0034] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
