Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 8A novel driving and steering system comprises a supporting mechanism 1, wherein the supporting mechanism 1 comprises a fixing plate 11 symmetrically arranged in a square shape, wherein a fixing sleeve 12 is fixedly connected to the surface of each fixing plate 11, a supporting rod 13 is arranged between the two sleeves 12, and both ends of the supporting rod 13 are respectively slidably connected to the inner wall of the sleeve 12, and the lower surface of one of the supporting rods 13 is fixedly connected to the surface of one of the fixing plates 11, and a first hydraulic rod 14 is arranged on one side of each transverse supporting rod 13, and a second hydraulic rod 15 is arranged on one side of each longitudinal supporting rod 13, and both ends of the first hydraulic rod 14 and the second hydraulic rod 15 are respectively fixedly connected to the side surfaces of the two fixing plates 11 opposite to the two sides thereof, wherein the side surfaces of the two fixing plates 11 are respectively fixedly embedded with cameras 16, and the lower surface of one of the fixing plates 11 is fixedly connected with a controller, and a driving component 2 is arranged below the supporting mechanism 1;

[0030] In order to realize the driving and steering of the entire equipment by the driving component 2 to cross the obstacle, the driving component 2 is provided to include an electric telescopic rod 21 whose upper end is embedded in the body of the fixed plate 11, and an electromagnetic brake 22 is fixedly sleeved at the middle position of the outer surface of the electric telescopic rod 21. The upper end of the electromagnetic brake 22 is fixedly connected to the lower end of the rod body at the top of the electric telescopic rod 21, and the braking part of the electromagnetic brake 22 is provided with a silicone gasket. The braking part of the electromagnetic brake 22 is connected to the lower rod body of the electric telescopic rod 21. The outer surface is movably connected, and a placement cylinder 23 is arranged below the electric telescopic rod 21; a spring 24 is arranged inside the placement cylinder 23, and circular plates 25 are fixedly connected to the upper and lower ends of the spring 24, respectively. The side of the circular plate 25 located at the lower end of the spring 24 is fixedly connected to the inner wall of the placement cylinder 23, and the side of the circular plate 25 located at the upper end of the spring 24 is slidably connected to the inner wall of the placement cylinder 23. The upper surface of the circular plate 25 located at the upper end of the spring 24 is fixedly connected to the lower end of the electric telescopic rod 21, and a power mechanism 26 is arranged at the lower end of the placement cylinder 23;

[0031] Specifically, the electric telescopic rod 21 can realize flexible adjustment of the height of the equipment; when encountering obstacles of different heights, the height of the entire equipment can be adjusted by extending or contracting the electric telescopic rod 21, so as to better cross the obstacles. At the same time, the fast response characteristics of the electric telescopic rod 21 enable the equipment to complete the height adjustment in a short time, thereby improving the working efficiency of the equipment;

[0032] The setting of the electromagnetic brake 22 provides an important guarantee for the safe operation of the equipment; when the electric telescopic rod 21 is kept at a specific position, the electromagnetic brake 22 can brake quickly, and ensure the stability of the equipment by cooperating with the electric telescopic rod 21; the presence of the silicone gasket not only increases the friction during braking and improves the braking effect, but also reduces the wear of the electric telescopic rod 21 during braking and prolongs its service life;

[0033] The placement cylinder 23 plays a role of connection and support; on the one hand, it provides installation space for the components under the electric telescopic rod 21, making the structure of the entire driving component more compact; on the other hand, the placement cylinder 23 can accommodate buffer devices such as springs 24, which can absorb vibrations and impacts during the driving of the equipment and protect other parts of the equipment from damage; at the same time, the placement cylinder 23 is designed with high-strength materials to ensure that it remains stable when bearing the weight of the equipment and various external forces.

[0034] In this embodiment, the power mechanism 26 includes a first motor 261, which is located inside the placement cylinder 23. The output shaft of the first motor 261 is rotatably connected to the inner bottom wall of the placement cylinder 23 through a bearing. The output shaft of the first motor 261 passes through the inner bottom wall of the placement cylinder 23 and is fixedly connected to a first gear 262. The surface of the first gear 262 is meshed with a second gear 263. The center position of the second gear 263 is rotatably connected to the bottom of the placement cylinder 23 through a pin shaft fixedly connected to a bearing at one end. A limit plate 264 is provided below the second gear 263. The upper surface of the limit plate 264 is provided with a connecting rod 265. The upper end of each connecting rod 265 is fixedly connected to the bottom outer surface of the placement cylinder 23, and the lower end of the pin shaft extends to the bottom of the limit plate 264. A rotating plate 266 is provided below the rotating plate 266, the lower end of the pin is fixedly connected to the plate body of the rotating plate 266, an auxiliary connecting rod 267 is fixedly connected to the lower surface of the rotating plate 266, a fixing frame 268 is provided below the rotating plate 266, the lower end of the auxiliary connecting rod 267 is fixedly connected to the upper end of the fixing frame 268, a steering wheel 269 is provided at the lower end of the fixing frame 268, the steering wheel 269 is rotatably connected to the inner side surface of the fixing frame 268 through a connecting shaft, one end of the connecting shaft passes through the frame body of the fixing frame 268 and extends to the outside, one end of the connecting shaft is fixedly connected to a gear box 2612, one of the gears of the gear box 2612 is fixedly connected to a rotating column 2611, the upper end of the rotating column 2611 is fixedly connected to a second motor 2610, and the surface of the second motor 2610 is fixedly connected to the surface of the fixing frame 268;

[0035] Specifically, by setting the above structure, the entire device can achieve multi-angle steering, including special steering actions such as rotation on the spot, which is very useful in some scenarios that require precise alignment or complex operations in a small space; each power mechanism 26 can provide independent power for the corresponding steering wheel, so that the equipment has stronger power when facing different road conditions and loads; the independent power mechanism 26 makes maintenance and repair more convenient; each power mechanism 26 can be disassembled and repaired separately without large-scale disassembly of the entire system; this reduces maintenance costs and repair difficulties, and improves the maintainability of the equipment.

[0036] In this embodiment, the steering wheel 269 is a Mack master wheel, and the tire surface of the Mack master wheel is made of special anti-slip material silicone rubber and texture design; specifically, whether it is a dry cement ground, a wet stone road or a muddy dirt road, the Mack master wheel with silicone rubber and texture design can provide strong grip, which makes the device more stable during driving and less prone to slipping, especially when accelerating, decelerating and turning, which can ensure that the device runs according to the predetermined trajectory. At the same time, each steering wheel 269 has a separate drive motor. The separate drive motor enables the steering wheel 269 to achieve multi-angle steering, including movement in all directions of front, back, left and right. This multi-angle steering capability allows the device to more flexibly adjust its position and direction in different working scenarios. The design of the independent drive motor provides more powerful power output and improves the acceleration performance and climbing ability of the equipment.

[0037] In this embodiment, the telescopic speed of the electric telescopic rod 21 is adjustable; through the above settings, it is satisfied that under different terrain conditions, the equipment needs to adjust its height to better pass obstacles or adapt to terrain changes. When encountering a higher obstacle, the telescopic speed of the electric telescopic rod 21 can be reduced to ensure that the equipment is stably raised to a higher height and avoid instability or accidental collision caused by over-rapid telescopic movement. On a relatively flat terrain, the electric telescopic rod 21 can appropriately speed up the telescopic speed to improve the passing efficiency of the equipment.

[0038] In this embodiment, the material of the placement tube 23 is a high-strength, corrosion-resistant alloy material; by setting the above structure, the placement tube 23 is guaranteed to be used normally under long-term and high-frequency contact with the soil, reducing the number of equipment replacements to adapt to different agricultural environments.

[0039] In this embodiment, a lubricating layer is provided inside the fixed sleeve 12, and the lubricating layer reduces the friction resistance when the support rod 13 slides, thereby improving the operating efficiency and service life of the system.

[0040] In this embodiment, the controller includes a communication module and an autonomous learning module. The communication module uploads the learned data to the cloud for analysis and processing. The autonomous learning module includes a data acquisition unit, a model training unit, a model evaluation unit, a model storage unit and a fault self-diagnosis unit. The data acquisition unit is responsible for collecting data from various sensors and input devices, including data collected by the camera 16. The model training unit uses a machine learning algorithm to train the collected data and establish a control model. During the training process, the model training module continuously adjusts the parameters of the model to improve the accuracy and generalization ability of the model. The model evaluation unit evaluates the trained model to determine whether its performance meets the requirements. The model storage unit regularly updates and optimizes the model. The fault self-diagnosis unit issues an alarm for problems caused by the equipment and displays the cause of the fault to facilitate maintenance.

[0041] Reference Figure 1-Figure 8 , the operation method of a new driving and steering system is as follows:

[0042] Step 1: When the device encounters an obstacle while driving on a flat road, the camera 16 located in front transmits the captured image to the controller. The controller determines the size and height of the obstacle in front through an algorithm, and then controls the height of the electric telescopic rod 21. When it is determined that the device can cross the obstacle normally, the electromagnetic brake 22 starts to work synchronously, and the electromagnetic brake 22 fixes the telescopic rod body to keep the device at a safe height;

[0043] Step 2, at the same time, the first hydraulic rod 14 and the second hydraulic rod 15 coordinate and cooperate to adjust the length of the extension of the support rod 13 of the equipment. During the extension of the support rod 13, the controller controls the first motor 261 to work, and the first motor 261 drives the second gear 263 to rotate through the first gear 262, and the second gear 263 drives the fixed frame 268 to rotate. At this time, the steering wheel 269 rotates the deflection angle under the action of the second motor 2610, the rotating column 2611 and the gear box 2612. The multiple power mechanisms 26 of the entire equipment work synchronously, and the deflection angles of the steering wheels 269 on both sides are facing outward, and the deflection angles are in opposite directions to meet the safety width of the entire equipment;

[0044] Step three, when the equipment is turning, the rotating space does not have a large turning range. At this time, the first hydraulic rod 14 and the second hydraulic rod 15 coordinate and shorten appropriately. At the same time, the second motor 2610 and the first motor 261 of each independent power mechanism 26 rotate synchronously. The rotation angle and direction of the entire equipment change with the deflection and deflection angle of each power mechanism 26, and the in-situ rotation is completed at the maximum deflection angle.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
