[0002] The high-precision topographic mapping UAV payload device is a modular device designed specifically for UAVs. It is used to carry the mapping module (i.e., the payload, which is a sensor or device that directly performs data acquisition, such as an optical camera, lidar, or RTK / PPK positioning system) and realize the acquisition and processing of topographic data. Its core function is to replace traditional manual mapping, improve efficiency and accuracy, and is widely used in land surveys, engineering construction and other fields. The mapping module needs to be connected to the UAV body through the payload device and relies on its power supply, communication and protection functions.

[0003] In existing technologies, when connecting a mapping module to the UAV body via a load device, a rigid connection is generally achieved through the engagement of threaded holes and bolts. However, since the position of the threaded holes is fixed, it only supports the installation of mapping modules of a single size and cannot be compatible with mapping modules of various specifications. Utility Model Content

[0006] The bottom of the UAV body is symmetrically provided with upright plates, and two upright plates are movably connected to symmetrically arranged load frames. The load frames have symmetrically opened long slots for threaded columns to pass through, and the long slots cooperate with the threaded columns and nuts to realize the installation between the mapping module and the load frame. An adjustment mechanism is provided between the two upright plates to pass through the load frame, and the adjustment mechanism is used to adjust the installation width. The adjustment mechanism includes a bidirectional lead screw connected to the upright plate through a bearing and a handle movably connected to one side of the bidirectional lead screw.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 and Figure 5 This utility model provides a technical solution: a high-precision terrain mapping UAV payload device, including a UAV body 1 and a mapping module 2. The UAV body 1 is set above the mapping module 2. Threaded posts 8 are symmetrically arranged at the top of the mapping module 2, and nuts 9 are threadedly connected to the surface of the threaded posts 8.

[0024] The bottom of the UAV body 1 is symmetrically provided with upright plates 4. The two upright plates 4 are movably connected to the symmetrically arranged load frame 3. The load frame 3 has symmetrically opened long slots 301 for threaded columns 8 to pass through. The long slots 301 cooperate with the threaded columns 8 and nuts 9 to realize the installation between the mapping module 2 and the load frame 3.

[0025] Specifically, since the threaded post 8 is slidably connected to the long slot 301, after the threaded post 8 at the top of the mapping module 2 passes through the long slot 301, the mapping module 2 can be moved back and forth to adjust it to the middle position at the bottom of the UAV body 1. At this time, the nut 9 is put on the outside of the threaded post 8 and tightened, thereby completing the installation of the mapping module 2. By adopting this operation, the installation of mapping modules 2 of different specifications can be adapted.

[0026] The UAV body 1 drives the surveying module 2 to move, so that the surveying module 2 can realize high-precision surveying of terrain data and improve efficiency. The surveying module 2 relies on the power supply, communication and protection functions of the UAV body 1.

[0027] exist Figure 2 and Figure 3 In the middle: elastic pads 7 are provided at both the upper and lower ends of the load frame 3. The elastic pads 7 are made of silicone.

[0028] Specifically, the elastic pad 7 can prevent hard contact between the surveying module 2, the nut 9 and the load frame 3, thus providing protection. At the same time, it can increase friction and improve installation stability.

[0029] exist Figures 1-5 In the middle: An adjustment mechanism 5 is provided between the two upright plates 4, which passes through the load frame 3. The adjustment mechanism 5 is used to adjust the installation width. The adjustment mechanism 5 includes a double-acting screw 501 connected to the upright plate 4 through a bearing and a guide rod 503 symmetrically welded between the two upright plates 4. The double-acting screw 501 is threadedly connected to the load frame 3. A handle 502 is movably connected to one side of the double-acting screw 501. The double-acting screw 501 is used to make the two load frames 3 move synchronously in opposite directions.

[0030] Specifically, since the load frame 3 is threadedly connected to the bidirectional lead screw 501 and slidably connected to the guide rod 503, the symmetrically arranged load frame 3 can be moved in the opposite direction in the horizontal direction by rotating the handle 502 and the bidirectional lead screw 501, thereby realizing the adjustment of the installation width to adapt to the installation of different specifications of surveying modules 2.

[0031] exist Figures 1-3 and Figure 5 In the middle: the guide rod 503 is slidably connected to the load frame 3, and the guide rod 503 is used to make the load frame 3 only perform linear motion.

[0032] Specifically, the guide rod 503 can be used to support and limit the load frame 3, so that the load frame 3 can only move in a straight line.

[0033] exist Figure 3 and Figure 4 In the middle: A positioning mechanism 6 is provided between the handle 502 and the double-acting lead screw 501. The positioning mechanism 6 is used to improve the stability after the installation width is adjusted. The positioning mechanism 6 includes a movable column 601 fixed on the side of the handle 502 and a movable groove 603 opened on one side of the double-acting lead screw 501. A return spring 602 is connected between the movable column 601 and the movable groove 603. The return spring 602 is used to make the movable column 601 automatically return to its original position. Positioning columns 604 are symmetrically arranged on the side of the handle 502. A positioning groove 605 is opened at equal angles on the side of a vertical plate 4 to form a locking structure with the positioning column 604. The positioning column 604 and the positioning groove 605 cooperate to lock the handle 502 and prevent the handle 502 from rotating.

[0034] Specifically, since the movable column 601 and the movable groove 603 are elastically connected by the return spring 602 and slidably connected by the limiting block 606 and the limiting groove 607, the return spring 602 can be stretched by pulling the handle 502 outward, which in turn separates the positioning column 604 from the positioning groove 605. At this time, the locking of the handle 502 can be released, allowing the handle 502 to rotate. After the load frame 3 is adjusted to the designated position, the handle 502 is released, and the handle 502 and the movable column 601 will automatically reset under the action of the return spring 602. At the same time, the positioning column 604 will engage with the positioning groove 605, thereby locking the handle 502 to prevent the handle 502 from rotating on its own.

[0035] exist Figure 4 In the middle: the inner surface of the movable groove 603 is symmetrically provided with limiting grooves 607, and the upper and lower ends of the movable column 601 are provided with limiting blocks 606 that form a sliding structure with the limiting grooves 607. The limiting grooves 607 and the limiting blocks 606 cooperate to make the bidirectional lead screw 501 rotate synchronously with the movable column 601.

[0036] Specifically, through the cooperation of the limiting groove 607 and the limiting block 606, the bidirectional lead screw 501 can rotate synchronously with the movable column 601.

[0037] In use, the return spring 602 can be stretched by pulling the handle 502 outward, which will simultaneously separate the positioning post 604 from the positioning groove 605. At this time, the lock on the handle 502 can be released. Then, the handle 502 and the two-way screw 501 can be rotated as needed, so that the symmetrically arranged load frame 3 can move in the opposite direction in the horizontal direction, thereby completing the adjustment of the installation width. After the handle 502 is released, it and the movable post 601 will automatically reset under the action of the return spring 602, and at the same time, the positioning post 604 will engage with the positioning groove 605, thereby locking the handle 502. At this time, the threaded post 8 at the top of the mapping module 2 is inserted through the long groove 301, and the mapping module 2 is adjusted to the middle position of the bottom of the UAV body 1 by moving the mapping module 2 back and forth. Then, the nut 9 is put on the outside of the threaded post 8 and tightened, thereby completing the installation of the mapping module 2.

[0038] Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source and controlled by a control box. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
