Description

Technical Field

[0001] This utility model relates to the field of land and air exploration equipment technology, specifically to an unmanned aerial vehicle for land and air exploration. Background Technology

[0002] In the field of modern detection technology, land-air detection equipment plays an important role in many scenarios such as emergency rescue, environmental monitoring, and geographic mapping because it has the dual functions of land detection and air detection. In order to achieve the integration of land-air detection functions, existing technologies usually directly integrate the functions of remote control vehicles and drones to build land-air detection equipment that can flexibly switch between land driving and air flight modes. This design greatly expands the application scope and environmental adaptability of detection equipment, and significantly improves detection efficiency and flexibility.

[0003] However, in practical applications, in land mode, to avoid the flying arm interfering with land travel, a set of motors is needed to drive the flying arm to retract. In flight mode, to reduce air resistance and ensure flight stability, another set of motors is needed to drive the walking arm to retract. This design, which uses two independent motors to control the retraction and extension of components, inevitably increases the overall weight of the equipment. The additional motors not only occupy internal space but also increase the load on the equipment, which in turn significantly increases the overall energy consumption of the equipment. This severely limits the equipment's endurance and working time, affects the equipment's continuous detection performance and user experience in complex environments, and fails to meet the growing demand for efficient and low-power detection. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an unmanned aerial vehicle for land and air exploration, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an unmanned aerial vehicle for land and air exploration, comprising a main body, a fixed bracket fixed at the middle position inside the main body, and a dual-axis drive motor installed inside the fixed bracket, a walking mechanism provided at the four corners of the bottom of the main body, and a flight mechanism provided at the top inside the main body;

[0006] The two sets of output ends of the dual-axis drive motor are fixed with first drive gears on the outside. The fixed bracket is rotatably connected to the two sides of the second drive gears that mesh with the first drive gears. The movable shafts of the first and second drive gears are fixed with walking arms. The four corners of the top of the main body are rotatably connected with transmission gears. The first and second drive gears are respectively meshed with first racks, and the ends of the first racks are fixed with second racks that mesh with the transmission gears. The rotating shafts of the four sets of transmission gears are all fixed with flying arms.

[0007] The walking mechanism also includes an electric wheel and a transmission rod. The electric wheel is installed at the end of the walking arm and plays the role of walking. The second drive gear and the fixed bracket are rotatably connected through the transmission rod.

[0008] The flight mechanism also includes a fixed frame, on both sides of which are rotatably connected to transmission gears via rotating shafts. The flight mechanism also includes a flight motor module, which is installed at the end of the flight arm and consists of a brushless motor and blades.

[0009] The main body has storage cavities that cooperate with the four sets of flight mechanisms, and the storage cavities serve to store the flight mechanisms.

[0010] By adopting the above technical solution, this land and air exploration unmanned aerial vehicle effectively solves the problems of large weight and high energy consumption caused by the traditional equipment using two independent motors through a single-motor driven gear and rack linkage structure. The dual-axis drive motor synchronously controls the extension and retraction of the walking arm and the flying arm through the first drive gear, and realizes the reverse linkage between the two through gear and rack transmission. The switching between land and flight modes can be completed without additional motors, reducing the number of motors and internal space occupation, reducing the overall weight and energy consumption of the equipment, and improving the endurance.

[0011] Furthermore, a fixed guide rod is fixed inside the main body, which passes through the two sets of second racks, and the fixed guide rod plays a guiding role when the two sets of second racks slide.

[0012] By adopting the above technical solution, the fixed guide rod passes through the second rack, ensuring its linear sliding and improving the stability of the transmission process.

[0013] In summary, the present invention has the following main advantages:

[0014] 1. This utility model, through a single-motor driven gear and rack linkage structure, effectively solves the problems of large weight and high energy consumption caused by the traditional equipment using two independent motors. The dual-axis drive motor synchronously controls the extension and retraction of the walking arm and the flying arm through the first drive gear, and realizes the reverse linkage between the two by using gear and rack transmission. The switching between land and flight modes can be completed without additional motors, reducing the number of motors and internal space occupation, reducing the overall weight and energy consumption of the equipment, and improving the endurance.

[0015] 2. In land mode, the flight arm is retracted into the internal storage cavity of the main body, avoiding interference with ground driving and improving passability. In flight mode, the retracted walking arm reduces air resistance and provides stable lift in conjunction with the unfolded flight arm, improving flight stability. The single-motor drive scheme simplifies the transmission structure, reduces the complexity of multi-motor collaborative work, reduces the risk of failure, and shortens the mode switching time. It is suitable for scenarios with high requirements for equipment response speed and continuous working capability, such as emergency rescue and environmental monitoring, thus expanding the application scope and environmental adaptability of the equipment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Example 1

[0026] like Figure 1-6As shown, this embodiment focuses on unmanned aerial vehicles for land and air exploration. Its structural design focuses on single-motor dual-mode drive and compact storage. It is mainly composed of a main body 1, a fixed bracket 2, a dual-axis drive motor 3, a walking mechanism 4, and a flight mechanism 5.

[0027] The main body 1 has a fixed bracket 2 inside for mounting a dual-axis drive motor 3. The top and bottom four corners are respectively set with a flight mechanism 5 and a walking mechanism 4, and the interior has a storage cavity 8 that matches the flight mechanism 5.

[0028] The dual-axis drive motor 3 is fixed to the fixed bracket 2, and the two sets of output ends are respectively connected to the first drive gear 401. Through the gear and rack transmission structure, the retraction and extension actions of the walking mechanism 4 and the flying mechanism 5 are synchronously controlled.

[0029] The first drive gear 401 meshes with the second drive gear 402. The second drive gear 402 is rotatably connected to the fixed bracket 2 through the transmission rod 405. The first drive gear 401 is fixed on the outside of the output shaft of the dual-shaft drive motor 3. The walking arm 403 is fixed on the outside of the gear movable shaft, and the electric wheel 404 is installed at the end.

[0030] In land mode, the walking arm 403 tilts downwards, and the electric wheel 404 touches the ground to drive the equipment. When not in use, the walking arm 403 can be flipped upwards and stored at the bottom of the main body 1.

[0031] The first drive gear 401 drives the second rack 7 through the first rack 6. The second rack 7 meshes with the transmission gear 504. The transmission gear 504 is connected to the flight arm 502 through the rotating shaft 503, and the flight motor module 505 is installed at the end.

[0032] In flight mode, the flight arm 502 extends from the storage cavity 8 to the outside of the main body 1, and the flight motor module 505 starts to provide lift. When not in operation, the flight arm 502 is stored inside the main body 1.

[0033] The dual-axis drive motor 3 drives the second drive gear 402 on one side through the first drive gear 401 to control the rotation of the walking arm 403, and on the other side through the first rack 6, the second rack 7, and the transmission gear 504 to control the unfolding of the flying arm 502, so that the two movements are synchronized and reversed.

[0034] The fixed guide rod 9 passes through the second rack 7 to ensure its linear sliding and improve the stability of the transmission process.

[0035] The working principle of this utility model is as follows: When in use, the main body 1 is equipped with a control module and a power supply module. The control module controls the overall equipment, and the power supply module supplies power to the overall equipment.

[0036] When walking in land mode, the four walking mechanisms 4 are located below the main body 1. Under the action of the four electric wheels 404, the whole device can walk on the ground. At this time, the four flying mechanisms 5 flip into the storage cavity 8 inside the main body 1, so as not to affect the overall walking effect, thereby improving the overall passability and applicability.

[0037] When it is necessary to switch to flight model flight, the dual-axis drive motor 3 starts and drives the two sets of first drive gears 401 to rotate. Since the middle part between the first drive gear 401 and the second drive gear 402 fits each other, the first drive gear 401 and the second drive gear 402, which rotate in both directions, drive the two sets of walking arms 403 to flip and lift, thereby causing the walking arms 403 to flip and lift to the bottom of the main body 1.

[0038] At the same time, when the first drive gear 401 and the second drive gear 402 rotate, they respectively mesh with the first rack 6 to move. The movement of the first rack 6 drives the second rack 7 to move. Since the second rack 7 meshes with the transmission gear 504, it drives the four sets of flight arms 502 to rotate along the rotating shaft 503. Thus, the four sets of flight arms 502 drive the flight motor module 505 to extend out of the storage cavity 8. Then the flight motor module 505 starts, and the main body 1 is driven to perform flight operation by rotating the blades.

[0039] In summary, by using a dual-axis drive motor 3 and a gear and rack transmission structure to replace the traditional two independent motors, the number of motors is reduced, the overall weight of the equipment and the internal space occupied are reduced, and a single motor realizes the retraction and extension control of the walking arm 403 and the flying arm 502, avoiding the energy loss of multiple motors working together, improving the equipment's endurance and working time. The flying arm 502 is stored in land mode and the walking arm 403 is stored in flight mode, which reduces interference with land driving and air flight, respectively, improves the stability and passability of the equipment in different modes, and expands the application scenarios.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
