Description

Technical Field

[0001] The utility model relates to the technical field of surveying instruments, and in particular to a foldable flying wing for a surveying instrument. Background Art

[0002] A drone mapping system combines drones with surveying and mapping technology to acquire geospatial data. It can quickly acquire terrain data over large areas, creating topographic maps and contour maps, providing fundamental data support for urban planning, land development, road construction, and other fields. Compared to traditional manual surveying methods, drone mapping can quickly cover large areas, significantly improving surveying and mapping efficiency. For example, when surveying in complex mountainous areas, drones can easily reach hard-to-reach areas and acquire large amounts of data in a short period of time.

[0003] Traditional surveying instruments often use drone wings with integrated, detachable two-wing structures. For example, the eight-rotor drone and its wing-arm knob-type detachable components disclosed in announcement number CN207045661U include a fuselage and eight evenly spaced wing arms, each with a motor and rotor mounted at its outer end. Removable landing gear is symmetrically distributed below the fuselage's outer sides, with knob-type detachable components located at the hinges of each wing arm. This drone features eight evenly spaced rotors, simplifying its structure while improving reliability. The wing-arm folding mechanism is a new quick-release mechanism for easy installation and removal. The first aid kit, landing gear, and battery are nested together, evenly distributing the overall mass, improving space utilization, and increasing overall stability. The landing gear can be quickly removed, simplifying maintenance.

[0004] However, the above-mentioned UAV flying wing still has the following problems: since the two wings of the UAV flying wing occupy a large space, it is not conducive to recycling in a limited space. The above-mentioned UAV flying wing is designed with a detachable form of quick-release parts, but the flying wing as a whole needs to be removed from the wing arm, and it needs to be repeatedly installed when needed, which is very inconvenient and affects the efficiency of use.

[0027] See also Figure 2 and Figure 4 The first wing arm structure 32 includes a first wing rod 321, one end of the first wing rod 321 is fixed with a first ring 322, and first locking holes 323 are opened on both sides of the top surface of the first ring 322 to facilitate the locking structure 35 to lock and fix the first wing arm structure 32.

[0028] See also Figure 2 and Figure 5 The second wing arm structure 33 includes a second wing rod 331, one end of the second wing rod 331 is fixed with a second ring 332, and second locking holes 333 are opened on both sides of the inner ring wall of the second ring 332 to facilitate the locking structure 35 to lock and fix the second wing arm structure 33.

[0029] It should be noted that the bottom surface of the first ring 322 and the top surface of the second ring 332 are provided with mutually matching beveled surfaces. When in flight, the first wing arm structure 32 and the second wing arm structure 33 are as follows. Figure 1 As shown, the bottom surface of the first ring 322 and the top oblique surface of the second ring 332 are completely fitted together, and the first ring 322 and the second ring 332 are combined into a cylindrical shape.

[0030] See also Figure 2 and Figure 6The locking structure 35 includes a telescopic rod 351, a pressure cover 352 is fixed to the top of the telescopic rod 351, and locking rods 353 adapted to the first locking hole 323 are fixed on both sides of the bottom surface of the pressure cover 352. A pressure plate 354 is fixed to the bottom end of the telescopic rod 351, and a conical pressure block 355 is fixed to the outside of the telescopic rod 351. In the initial state, the telescopic rod 351 tends to shrink downward under the elastic force of the second spring 36, that is, the conical pressure block 355 is in a low position.

[0031] See also Figure 2 and Figure 7 The outer side of the fixed column 31 is provided with a stop ring 311, and a guide strip 312 is provided above the stop ring 311 and is slidably connected to the second ring 332. The top of the fixed column 31 is provided with a rotating ring 313 rotatably connected to the first ring 322. The bottom inner side of the fixed column 31 is provided with a first chamber 314 for sliding the pressure plate 354.

When the telescopic rod 351 is pulled upward by the pressure cover 352 to cause the pressure plate 354 to compress the second spring 36 and move upward, the conical pressure block 355 moves upward synchronously to gradually reduce the pressure on the ball heads 317 on both sides, so that the two ball heads 317 can be disengaged from the two second locking holes 333 of the second ring 332 and shrink into the inner side of the limiting groove 316, thereby releasing the lock of the first wing-arm structure 32 and the second wing-arm structure 33.

[0032] Specifically, the first spring 34 is sleeved outside the fixing column 31 , one end of the first spring 34 abuts against the stop ring 311 , and the other end of the first spring 34 abuts against the second sleeve ring 332 .

[0033] Specifically, the second spring 36 is sleeved outside the telescopic rod 351 , one end of the second spring 36 abuts against the pressure plate 354 , and the other end of the second spring 36 abuts against the top wall of the first chamber 314 .

[0034] The working principle and use process of the utility model are as follows: in the initial state, the flying wing is as follows: Figure 1 As shown, when folding and recycling is required, the telescopic rod 351 can be pulled upward by the pressing cover 352, so that the pressure plate 354 compresses the second spring 36 and moves upward. During this process, the locking rod 353 on the bottom surface of the pressing cover 352 can be withdrawn from the two first locking holes 323 on the first collar 322, and the upward movement of the conical pressing block 355 gradually reduces the pressure on the ball heads 317 on both sides, so that the two ball heads 317 can be disengaged from the two second locking holes 333 of the second collar 332 and shrink into the inner side of the limiting groove 316, thereby releasing the lock of the first wing-arm structure 32 and the second wing-arm structure 33.

[0035] Then rotate the first wing arm structure 32, and the mutual compression of the bottom of the first ring 322 and the top oblique surface of the second ring 332 can make the second ring 332 compress the first spring 34 downward. After the first wing arm structure 32 is rotated to 180 degrees, the pressure cover 352 is released, and the locking rods 353 on both sides of the bottom surface of the pressure cover 352 can be automatically inserted into the two first locking holes 323 on the first ring 322 under the elastic force of the second spring 36, thereby locking the first wing arm structure 32. At this time, due to the top pressure of the bottom of the first ring 322 and the top oblique surface of the second ring 332, the second wing arm structure 33 also remains stable, realizing the rotational folding of the first wing arm structure 32 toward the second wing arm structure 33, thereby reducing the proportion of the overhanging space of the first wing arm structure 32 and the second wing arm structure 33, so as to facilitate the small space folding and recovery of the flying wing.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
