Description

Technical Field

[0001] This invention relates to the field of terrain surveying, and in particular to a vehicle for surveying complex terrain in the field. Background Technology

[0002] With the increasing demand for Earth science research, resource exploration and environmental monitoring, higher requirements have been placed on the exploration and sample collection work in complex terrain, especially in the field environment. Traditional terrain exploration vehicles are mostly designed for flat or relatively regular terrain, so they are difficult to meet the effective exploration and sampling tasks in complex terrain such as mountains, deserts and jungles.

[0003] In particular, when conducting surveys in jungles, the tall and dense vegetation in wild jungles often obstructs the path of the survey vehicle. Existing terrain survey vehicles, due to the height limitations of their fixed structures, have difficulty traversing dense vegetation areas, causing the vehicle to be unable to move forward smoothly and thus affecting the efficiency of terrain surveying. To solve the above problems, a field complex terrain survey vehicle is proposed.

[0004] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a field complex terrain exploration vehicle.

[0006] The present invention provides a field complex terrain exploration vehicle with the following technical solution:

[0007] A field complex terrain exploration vehicle includes a vehicle body and main wheels. Auxiliary frames and swing assemblies for driving the auxiliary frames are located on both sides of the front end of the vehicle body. Auxiliary wheels are located at the ends of the two auxiliary frames furthest from the vehicle body. Linkage frames are also rotatably mounted on both sides of the front end of the vehicle body, and a linkage wheel is rotatably mounted between the two linkage frames. When the swing assemblies drive the auxiliary frames to rotate, the linkage frames rotate synchronously with the auxiliary frames in opposite directions. A connecting rod is located on the side of each auxiliary frame furthest from the vehicle body, and the connecting rod rotates synchronously with the auxiliary frames. A protective plate is slidably mounted inside the vehicle body, and the protective plate unfolds or folds as the connecting rod rotates. An upper trailer plate and a lower trailer plate are provided inside the vehicle body, which can be synchronously raised and lowered relative to each other. A detection assembly is located on the upper trailer plate, and a sampling assembly is located on the lower trailer plate. When the protective plate is unfolded, the detection assembly is located below the protective plate.

[0008] Preferably, the swing assembly includes a connecting shaft, gear three, gear four, and motor one. The connecting shaft rotates within the vehicle body, and both ends of the connecting shaft are fixed to two auxiliary frames respectively. Gear three is fixed in the middle section of the connecting shaft. An installation groove for gear four to rotate is provided in the vehicle body. Motor one is fixed in the installation groove, and the rotor end of motor one is fixed to gear four. Gear four meshes with gear three.

[0009] Preferably, gear one is fixed at both ends of the connecting shaft, gear two is rotatable on both sides of the vehicle body, gear two is fixed to the linkage frame, gear two meshes with gear one, and sliding pins are provided on the side of the two linkage frames that are close to each other. Guide grooves for sliding pins are opened on both sides of the vehicle body, and the cross-section of the guide groove is concentric with the cross-section of gear two.

[0010] Preferably, the vehicle body has a sliding groove for the protective plate to slide, the connecting rods are provided with electric push rods on the side where they are close to each other, and the protective plate has insertion holes on both sides for inserting the telescopic ends of the power push rods.

[0011] Preferably, a through slot is provided in the vehicle body, a fixed frame is provided in the through slot, a gear five is rotatably provided in the fixed frame, a motor two is fixed in the fixed frame, the rotor end of the motor two is fixed to the gear five, a rack one and a rack two are slidably provided on both sides inside the fixed frame, the rack one and the rack two mesh with the gear five at the same time, the rack one is fixed to the upper trailer plate, the rack two is fixed to the lower trailer plate, there is always a gap between the rack two and the upper trailer plate, and there is always a gap between the rack one and the lower trailer plate.

[0012] Preferably, the detection component includes a viewfinder and a radar, both of which are mounted on the top of the upper slide plate.

[0013] Preferably, the sampling assembly includes a sampling cylinder, a rotating shaft, an auger blade, a drill bit, a third motor, and an output cylinder. The sampling cylinder is mounted on the lower slide plate, the rotating shaft rotates inside the sampling cylinder, the auger blade is fixed to the rotating shaft, the drill bit is fixed to the bottom end of the rotating shaft, the third motor is fixed to the top of the sampling cylinder, the rotor end of the third motor is fixed to the rotating shaft, and the output cylinder is fixed to one side of the sampling cylinder.

[0014] Preferably, a sampling port is provided on one side of the vehicle body for the output cylinder to pass through.

[0015] Preferably, when the upper and lower slide plates are fully retracted into the through slot, there is a gap between the top of the motor three and the gear five.

[0016] In summary, the present invention has the following beneficial technical effects:

[0017] 1. By setting auxiliary wheels and swing components on the vehicle body, as well as a linkage frame and linkage wheel, the swing components can drive the auxiliary wheels and linkage wheel to swing alternately in opposite directions. Compared with related technologies, this effectively improves the vehicle body's ability to pass through complex terrain. When facing obstacles of different heights and densities, the vehicle body's attitude can be flexibly adjusted, effectively overcoming the problem that traditional detection vehicles are difficult to pass through due to the height limitation of fixed structures. Especially in jungle environments, it can significantly reduce the obstruction of vegetation on the travel path, thereby improving detection efficiency.

[0018] 2. By sliding a protective plate inside the vehicle body and setting a connecting rod on the auxiliary frame, the connecting rod rotates synchronously with the auxiliary frame, and the protective plate unfolds or folds with the rotation of the connecting rod. Compared with related technologies, when crossing complex terrain, the unfolding of the protective plate can effectively protect the detection components, ensure the safety of the detection operation, reduce external interference, and thus help maintain the accuracy of the detection data.

[0019] 3. By installing an upper and lower trailer that can be raised and lowered synchronously inside the vehicle body, and each carrying a detection component and a sampling component, compared with related technologies, in complex terrain, especially in densely vegetated areas such as jungles, the height of the upper and lower trailers can be adjusted to ensure that the detection and sampling components are always in optimal working condition. This effectively reduces the operational difficulties caused by terrain limitations, thereby improving the efficiency and accuracy of detection and sampling. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0029] This invention discloses a field vehicle for surveying complex terrain. (Refer to...) Figure 1-7 A field complex terrain exploration vehicle includes a vehicle body 1 and main wheels 2. The number of main wheels 2 is even. Each main wheel 2 is equipped with an independent electric motor or hydraulic motor. Therefore, the power source of each main wheel 2 is independent and does not affect each other. Each main wheel 2 can also be angled, which is achieved through the steering mechanism in the suspension system. This part is a mature existing technology and will not be described in detail here.

[0030] It should be noted that vehicle 1 is also equipped with a communication system to report terrain information and any problems to the control center in real time; a navigation system, including GPS positioning, map data and route planning, to ensure that the exploration vehicle can reach the exploration target and return; communication equipment, including radio and satellite communication equipment, to ensure that the exploration vehicle can maintain contact with the control center; and a data recorder to record various data and information during the exploration process for retrieval and analysis when needed.

[0031] Reference Figure 1 , 2The front sides of the vehicle body 1 are provided with auxiliary frames 3 and swing components that drive the auxiliary frames 3 to rotate. The two auxiliary frames 3 are provided with auxiliary wheels 4 at the ends away from the vehicle body 1. The swing components include a connecting shaft 9, a gear 3 12, a gear 4 13, and a motor 14. The connecting shaft 9 rotates inside the vehicle body 1. The two ends of the connecting shaft 9 are fixed to the two auxiliary frames 3 respectively. The gear 3 12 is fixed in the middle section of the connecting shaft 9. The vehicle body 1 has a mounting groove 15 for the gear 4 13 to rotate. The motor 14 is fixed in the mounting groove 15. The rotor end of the motor 14 is fixed to the gear 4 13. The gear 4 13 meshes with the gear 3 12. When the motor 14 is started, the gear 4 13 drives the gear 3 12 and the connecting shaft 9 on it to rotate, thereby realizing the swing of the two auxiliary frames 3 and the auxiliary wheels 4 along the axis of the connecting shaft 9.

[0032] The front sides of the vehicle body 1 are also equipped with rotatable linkage frames 5, and rotatable linkage wheels 6 are provided between the two linkage frames 5. Gear 10 is fixed at both ends of the connecting shaft 9. Gear 21 is rotatable on both sides of the vehicle body 1. Gear 21 is fixed to the linkage frame 5 and meshes with gear 10. Sliding pins 7 are provided on the side of the two linkage frames 5 that are close to each other. Guide grooves 8 are provided on both sides of the vehicle body 1 for sliding pins 7. The cross section of the guide groove 8 is concentric with the cross section of gear 21. When the auxiliary frame 3 rotates, gear 10 drives gear 21 and its linkage frame 5 to rotate synchronously. At this time, the rotation direction of the linkage frame 5 is opposite to that of the auxiliary frame 3, thereby realizing the alternating swing of the auxiliary wheel 4 and the linkage wheel 6. This can not only effectively clear obstacles of different heights and densities, but also smoothly pass through complex terrains including steep peaks, rugged mountain roads, muddy mud, deserts and jungles, thereby effectively improving the ability of the vehicle body 1 to pass through complex terrains.

[0033] Reference Figure 3 Each of the two auxiliary frames 3 has a connecting rod 16 on the side away from the vehicle body 1. The connecting rod 16 rotates synchronously with the auxiliary frame 3. A protective plate 18 is slidably installed inside the vehicle body 1. A sliding groove 20 is opened inside the vehicle body 1 for the protective plate 18 to slide. Electric push rods 17 are provided on the side of the connecting rods 16 that are close to each other. Insertion holes 19 are opened on both sides of the protective plate 18 for inserting the telescopic ends of the electric push rods 17. When the electric push rods 17 are extended to be inserted into the insertion holes 19, the protective plate 18 can be unfolded with the rotation of the connecting rods 16. When the electric push rods 17 are retracted to cancel the insertion into the insertion holes 19, the protective plate 18 slides into the sliding groove 20 under the action of gravity.

[0034] Reference Figure 3-7The vehicle body 1 has a through slot 21, and a fixed frame 22 is provided in the through slot 21. A gear 23 is rotatably installed in the fixed frame 22. A motor 24 is fixed in the fixed frame 22. The rotor end of the motor 24 is fixed to the gear 23. A rack 1 25 and a rack 26 are slidably provided on both sides inside the fixed frame 22. The rack 1 25 and the rack 26 mesh with the gear 23 at the same time. The rack 1 25 is fixed to the upper carriage 27, and the rack 26 is fixed to the lower carriage 28. There is always a gap between the rack 26 and the upper carriage 27, and there is always a gap between the rack 1 25 and the lower carriage 28. When the motor 24 is started, the gear 5 23 rotates, which causes the rack 1 25 and its upper carriage 27 and the rack 26 and its upper and lower carriages 28 to move closer or further apart, thereby realizing the synchronous relative lifting and lowering of the upper carriage 27 and the lower carriage 28.

[0035] Reference Figure 4 The upper slide plate 27 is equipped with a detection component, which includes a viewfinder 36 and a radar 37. Both the viewfinder 36 and the radar 37 are mounted on the top of the upper slide plate 27. The connection method of the viewfinder 36 and the radar 37 is a mature and existing technology in the field, which will not be described in detail here.

[0036] It should be noted that the vehicle body 1 is also equipped with a gyroscope, accelerometer, magnetometer and distance sensor, which can be installed on the upper trailer 27 or on the top of the vehicle body 1 that can be covered by the protective plate 18, as needed, to obtain terrain and environmental information. When the protective plate 18 is unfolded, it can protect the detection components set on the top of the vehicle body 1, which helps to reduce external interference.

[0037] Reference Figure 4-7 A sampling assembly is provided on the lower slide plate 28. The sampling assembly includes a sampling cylinder 29, a rotating shaft 30, an auger blade 31, a drill bit 32, a motor 33, and an output cylinder 34. The sampling cylinder 29 is located on the lower slide plate 28. The rotating shaft 30 rotates inside the sampling cylinder 29. The auger blade 31 is fixed to the rotating shaft 30. The drill bit 32 is fixed to the bottom end of the rotating shaft 30. The motor 33 is fixed to the top of the sampling cylinder 29. The rotor end of the motor 33 is fixed to the rotating shaft 30. The output cylinder 34 is fixed. On one side of the sampling cylinder 29, a sampling port 35 is provided on the side of the vehicle body 1 for the output cylinder 34 to pass through. When the lower slide plate 28 descends to a suitable sampling height, the motor 33 is started to make the rotating shaft 30 and its auger blade 31 and drill bit 32 rotate. The drill bit 32 drills to loosen the ground sample. Under the conveying of the auger blade 31, the sample is conveyed into the output cylinder 34. The end of the output cylinder 34 can be equipped with a device for receiving the sample. The sample can be taken out through the sampling port 35.

[0038] It should be noted that when the upper slide plate 27 and the lower slide plate 28 are fully retracted into the through slot 21, there is a gap between the top of the motor 33 and the gear 5 23, which ensures the smooth lifting and lowering of the upper slide plate 27 and the lower slide plate 28. Due to the relative lifting and lowering of the upper slide plate 27 and the lower slide plate 28, in densely vegetated areas such as jungles, by adjusting the height of the upper slide plate 27 and the lower slide plate 28, it can be ensured that the detection components and sampling components are always in the best working condition, effectively reducing the operational difficulties caused by terrain limitations, and thus helping to improve the efficiency and accuracy of detection and sampling.
