It is typically equipped with various sensors and devices to acquire environmental information and transmit it to the operator or other systems for analysis and decision-making. Terrain-remote reconnaissance vehicles are usually equipped with a positioning system to facilitate the location and navigation of the reconnaissance vehicle. In my country, the BeiDou satellite system is commonly used for positioning.

[0003] However, existing remote-controlled terrain reconnaissance vehicles have the following problems in actual terrain reconnaissance: although they are adaptable to different terrains, their use in some special environments is limited, such as water areas and swamps, lacking good adaptive capabilities. Therefore, it is necessary to design corresponding technical solutions to address these problems. Summary of the Invention

The tire is divided into two groups and is respectively fitted into the front and rear of the loading hub. The closed cover plate is fixed to the front end of the loading hub with bolts. The pneumatic floating mechanism is installed in the drive shaft of the reconnaissance vehicle body and in the mounting groove. The drive blades are divided into several groups and evenly arranged in the mounting groove. The steering fine-tuning mechanism is divided into several groups and is distributed one-to-one with the several groups of drive blades. The loading hub includes an outer hub disc, an inner hub disc, and a sleeve. The outer hub disc and the inner hub disc are symmetrically arranged inside and outside and are connected by the sleeve. An annular groove is formed on the inner side of the inner hub disc. Several sets of air guide holes are evenly formed on the inner wall of the annular groove. Several sets of floating grooves are correspondingly formed on the inner walls of the outer hub disc and the inner hub disc. A reset pad is built into the upper end of the floating groove. The pneumatic floating mechanism includes an auxiliary pump body, an air guide pipe, an air flow ring, an air collection ring, and an annular expansion air cushion. The auxiliary pump body is mounted on the reconnaissance vehicle body and connected to the air flow ring through the air guide pipe. The air flow ring is movably fitted onto the drive shaft of the reconnaissance vehicle body and connected to the air collection ring on its inner side through an air pipe. An annular exhaust groove is provided on the inner side of the air collection ring. The annular exhaust groove is correspondingly set in the annular groove and the connection between the two is sealed. The annular expansion air cushion is fitted onto a sleeve and its inner side is connected to the air guide hole. The drive blade includes a floating block, a slider, an airbag column, and a blade body. The floating block is divided into two groups and slidably disposed in two symmetrical floating grooves. A sliding groove is opened in the middle of the floating block. The slider is slidably disposed in the sliding groove. The two ends of the airbag column are respectively disposed on the two groups of sliders. The blade body is fixed on the airbag column. The steering fine-tuning mechanism includes a micro motor, a rotating disk, a toggle block, and a stacked plate. The micro motor is installed at one end of the slide groove and its power output end is connected to the rotating disk. The toggle block is fixed to the edge of the rotating disk and contacts the slider. The stacked plate is installed at the other end of the slide groove.

[0006] In a preferred embodiment of the present invention, the tire is a tubeless tire and the surface is processed with anti-slip texture. The anti-slip texture is composed of several groups of rubber blocks with concave and convex shapes, and the surface of the rubber blocks has a wavy texture.

[0007] In a preferred embodiment of the present invention, the bottom of the annular expansion air cushion has an open structure and is connected to the air guide hole, and the edge of the annular expansion air cushion is sealed to the surface of the sleeve.

[0008] In a preferred embodiment of the present invention, the surface of the annular expansion air cushion is formed with a plurality of extrusion grooves, which are concentrically distributed and have an overall layered structure.

[0009] In a preferred embodiment of the present invention, both the reset pad and the laminated sheet are made of rubber material and the surface is processed into a laminated structure.

[0011] In a preferred embodiment of the present invention, the airbag column is a columnar airbag structure, the airbag column has an arc-shaped structure, and the curvature of the blade body is the same as the curvature of the airbag column.

[0012] As a preferred embodiment of the present invention, the specific operation is as follows: During remote operation, the terrain-controlled reconnaissance vehicle uses a Beidou locator for positioning. Under normal conditions, the vehicle can operate on various road surfaces. When it reaches water or swamp areas, the main pump inflates the airbag at the bottom of the vehicle, allowing it to remain suspended in the water. Once submerged, the auxiliary pump guides airflow through the air pipe into the airflow ring, and then through a pipe into the air collection ring. The air collection ring then directs the airflow into the annular expansion airbag, which gradually expands and pushes the drive blades outward along the floating groove. This allows the blades on the airbag to extend out of their mounting slots. In the water, the rotation of the loading hub and the drive blades allow the vehicle to move through the water. When fine-tuning the steering is required, a micro motor drives a rotating disk and a lever to adjust the angle of the drive blades, thus achieving steering.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention designs a terrain-remote reconnaissance vehicle adaptable to various terrain surveys. The terrain-remote reconnaissance vehicle includes a vehicle body, a vehicle floating component, hidden floating wheels, and a steering fine-tuning mechanism. Under normal conditions, the terrain-remote reconnaissance vehicle can operate normally on different road surfaces. When traveling to water or swamp areas, the vehicle floating component installed at the bottom of the vehicle can float and support the vehicle. In conjunction with the impeller mechanism installed inside the hidden floating wheels, normal operation in water and swamp areas can be achieved. In addition, the steering fine-tuning mechanism can adjust the angle of the impeller mechanism, enabling more precise control of the reconnaissance vehicle in water and swamp areas, greatly improving the adaptability and working range of the terrain-remote reconnaissance vehicle to different terrains.

[0014] 2. The terrain remote control reconnaissance vehicle designed in this invention can achieve high adaptability to different terrain areas and steering control capabilities, greatly improving the adaptability of the terrain remote control reconnaissance vehicle. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5This invention provides a technical solution: a terrain-controlled reconnaissance vehicle based on the BeiDou satellite system, comprising a reconnaissance vehicle body 1, a vehicle floating assembly, concealed floating wheels, and a steering fine-tuning mechanism. The front end of the reconnaissance vehicle body 1 is equipped with a BeiDou locator 2. The vehicle floating assembly is installed at the bottom of the reconnaissance vehicle body 1 and includes a main pump body 3, an air supply pipe 4, and an airbag cushion 5. The main pump body 3 is installed at the rear of the reconnaissance vehicle body 1 and connected to the airbag cushion 5 via the air supply pipe 4. The airbag cushion 5 is mounted on the bottom of the reconnaissance vehicle. Four sets of concealed floating wheels are evenly distributed below the reconnaissance vehicle body 1. The concealed floating wheels are installed on the reconnaissance vehicle body 1. At the end of the drive shaft of the vehicle body 1, the hidden floating wheel includes a loading hub 6, a tire 7, a closed cover plate 8, a pneumatic floating mechanism 9, and a drive blade 10. The middle area of ​​the loading hub 6 forms a mounting groove 11. The tire 7 is divided into two groups and is respectively fitted into the front and rear of the loading hub 6. The closed cover plate 8 is fixed to the front end of the loading hub 6 by bolts. The pneumatic floating mechanism 9 is installed in the drive shaft of the reconnaissance vehicle body 1 and in the mounting groove 11. The drive blade 10 is divided into several groups and evenly arranged in the mounting groove 11. The steering fine adjustment mechanism is divided into several groups and is distributed one-to-one with the several groups of drive blades 10. The loading hub 6 includes an outer hub disc 12, an inner hub disc 13, and a sleeve 14. The outer hub disc 12 and the inner hub disc 13 are symmetrically arranged inside and outside and are connected by the sleeve 14. An annular groove 15 is opened on the inner side of the inner hub disc 13. Several sets of air guide holes 16 are evenly opened on the inner wall of the annular groove 15. Several sets of floating grooves 17 are correspondingly arranged on the inner walls of the outer hub disc 12 and the inner hub disc 13. A reset pad 18 is built into the upper end of the floating groove 17. The pneumatic floating mechanism 9 includes an auxiliary pump body 19, an air guide pipe 20, an airflow ring 21, an air collection ring 22, and an annular expansion air cushion 23. The auxiliary pump body 19 is mounted on the reconnaissance vehicle body 1 and connected to the airflow ring 21 through the air guide pipe 20. The airflow ring 21 is movably fitted onto the drive shaft of the reconnaissance vehicle body 1 and its inner side is connected to the air collection ring 22 through an air pipe. An annular exhaust groove 24 is provided on the inner side of the air collection ring 22. The annular exhaust groove 24 is correspondingly arranged in the annular groove 15, and the connection between the two is sealed. The annular expansion air cushion 23 is fitted onto the sleeve 14 and its inner side is connected to the air guide pipe. With holes 16 connected, after the terrain remote reconnaissance vehicle is launched into the water, the auxiliary pump body 19 guides the airflow through the air guide pipe 20 into the airflow ring 21, and guides the gas in the airflow ring 21 into the gas collection ring 22 through the pipe. The gas collection ring 22 guides the airflow into the annular expansion air cushion 23. The annular expansion air cushion 23 gradually expands in the inflated state and pushes the drive blade 10 to move outward along the floating groove 17, so that the blade body 28 on the airbag column 27 can extend out of the mounting groove 11. In the water, the drive blade 10 rotates in the water by the rotation of the loading hub 6. The drive blade 10 includes a floating block 25, a slider 26, an airbag column 27, and a blade body 28. The floating block 25 is divided into two groups and slidably disposed in two symmetrical floating grooves 17. A sliding groove 29 is opened in the middle of the floating block 25, and the slider 26 is slidably disposed in the sliding groove 29. The two ends of the airbag column 27 are respectively disposed on the two groups of sliders 26. The blade body 28 is fixed on the airbag column 27. In water, the drive blade 10 rotates in the water by rotating the loading hub 6, thereby achieving the purpose of moving the terrain remote reconnaissance vehicle in water. The steering fine-tuning mechanism includes a micro motor 30, a rotating disk 31, a toggle block 32, and a stacked plate 33. The micro motor 30 is installed at one end of the slide groove 29 and its power output end is connected to the rotating disk 31. The toggle block 32 is fixed to the edge of the rotating disk 31 and contacts the slider 26. The stacked plate 33 is installed at the other end of the slide groove 29. When it is necessary to fine-tune the steering of the terrain remote reconnaissance vehicle, the micro motor 30 can drive the rotating disk 31 and the toggle block 32 to rotate and adjust, so that the toggle block 32 can act on the slider 26, and the drive blade 10 can be angled to achieve the purpose of steering.

[0019] Further improvements, such as Figure 3 As shown: Tire 7 is a tubeless tire with a surface textured to prevent slipping. The texture consists of several sets of convex and concave rubber blocks 34. The surface of the rubber blocks 34 has a wavy texture, which can achieve the purpose of preventing slipping.

[0020] Further improvements, such as Figure 5 As shown: The bottom of the annular expansion air cushion 23 has an open structure and is connected to the air guide hole 16. The edge of the annular expansion air cushion 23 is sealed to the surface of the sleeve 14. This design makes it easy to guide the airflow into the annular expansion air cushion 23 through the air guide hole 16.

[0021] Further improvements, such as Figure 5 As shown: The surface of the annular expansion air cushion 23 is formed with several sets of extrusion grooves 35. The several sets of extrusion grooves 35 are distributed concentrically and have an overall stacked structure. This design facilitates the adjustment of the volume of the annular expansion air cushion 23, thereby adjusting the position of the drive blade 10.

[0022] Further improvements, such as Figure 5 As shown: Both the reset pad 18 and the laminated sheet 33 are made of rubber and the surface is processed into a laminated structure, which can achieve the purpose of resetting the moving parts.

[0023] Further improvements, such as Figure 2 As shown: The height of the drive blade 10 is equal to half the depth of the mounting slot 11. When driving on the ground, the drive blade 10 can be kept in a retracted state, without affecting the normal operation of the vehicle.

[0024] Specifically, the airbag column 27 is a columnar airbag structure with an arc-shaped structure. The curvature of the blade body 28 is the same as that of the airbag column 27. This design facilitates the adjustment of the angle of the blade body 28, thereby achieving the purpose of fine-tuning the steering of the vehicle in water.

[0025] In use: The specific operation mode of this invention is as follows: During remote operation, the terrain-remote reconnaissance vehicle uses the Beidou locator 2 to locate itself. Under normal conditions, the vehicle can operate on various terrains. When it reaches water or swamp areas, the main pump 3 inflates the airbag 5 located at the bottom of the vehicle, allowing it to remain suspended after entering the water. Once submerged, the auxiliary pump 19 guides airflow through the air pipe 20 into the airflow ring 21, and then through a pipe into the air collection ring 22. The air collection ring 22 then directs the airflow into the annular expansion airbag 23. The annular expansion air cushion 23 gradually expands when inflated, pushing the drive blade 10 to move outward along the floating groove 17, so that the blade body 28 on the airbag column 27 can extend out of the mounting groove 11. In the water, the drive blade 10 rotates in the water by rotating the loading hub 6, thereby achieving the purpose of moving the terrain remote control reconnaissance vehicle in the water. When it is necessary to make fine adjustments to the steering of the terrain remote control reconnaissance vehicle, the micro motor 30 can drive the rotating disk 31 and the toggle block 32 to rotate and adjust, so that the toggle block 32 can act on the slider 26, so that the drive blade 10 can be adjusted in angle, thereby achieving the purpose of steering.
