[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] Example 1
[0026] like Figs. 1 to 3 As shown, this embodiment provides a driving and steering device suitable for desert environments, including an outer frame structure and an inner frame structure. The inner frame structure is located inside the outer frame structure. The outer frame structure includes an outer frame lifting foot 1 and a sliding track 7. The two sliding tracks 7 are arranged opposite to each other, and an outer frame lifting foot 1 is provided at each end of each sliding track 7. The inner frame structure includes an inner frame lifting foot 3, an internal working frame 4, and a rotating disk 10. The internal working frame 4 can slide along the sliding track 7, and the internal working frame 4 and the rotating disk 10 can rotate relative to each other. The inner frame lifting foot 3 is arranged on the rotating disk 10. Both the outer frame lifting foot 1 and the inner frame lifting foot 3 can extend and retract.
[0027] Specifically, in this embodiment, a support structure 2 is provided between the lifting and stopping feet 1 on the same side of the outer frame. The two support structures 2 are arranged in parallel and perpendicular to the sliding rail 7. The support structure 2 and the sliding rail 7 form the outer frame. The outer frame is not limited to the existing frame form and can be replaced with a protective frame, vehicle body frame, etc., according to different needs. The fixed ends of the lifting and stopping feet 1 are used to connect with the sliding rail 7 and the support structure 2, respectively, and the telescopic ends of the lifting and stopping feet 1 face downward.
[0028] This embodiment also includes a sliding power unit 5, which can drive the inner frame structure to slide along the sliding track 7. The sliding power unit 5 is not limited to existing cylinder power, but can also adopt engine power, electric power, and new energy power, etc., which can achieve extension and retraction, and can be changed according to changes in the working environment and working method. The fixed end of the sliding power unit 5 is set on the inner working frame 4 or the sliding track 7, and the telescopic end of the sliding power unit 5 is set on the sliding track 7 or the inner working frame 4.
[0029] In this embodiment, the internal working frame 4 is slidably connected to the sliding track 7 via a slider 6. There are at least two inner frame lifting feet 3, evenly distributed along the rotating disk 10. The fixed end of the inner frame lifting feet 3 is used to connect to the rotating disk 10, and the telescopic end of the inner frame lifting feet 3 is positioned downwards.
[0030] This embodiment also includes a rotary power unit 8, which can drive the internal working frame 4 and the rotating disk 10 to rotate relative to each other. The rotary power unit 8 is a motor and is installed on the internal working frame 4. The power output end of the rotary power unit 8 is provided with a rotary gear 9, which meshes with the rotating disk 10.
[0031] In this embodiment, both the outer frame lifting foot 1 and the inner frame lifting foot 3 are retractable structures such as cylinders, hydraulic cylinders, or electric telescopic rods.
[0032] When the equipment enters the work site, such as Fig. 2 As shown, both the outer frame lifting foot 1 and the inner frame lifting foot 3 are in contact with the ground. The outer lifting foot slowly rises from the ground to a designated position, and the sliding power unit 5 drives the inner frame structure to slide along the sliding track 7 to the designated position. After stopping, the outer lifting foot slowly falls until it contacts the ground. At the same time, the inner frame lifting foot 3 starts to operate, slowly rising from the ground to a designated position, and the sliding power unit 5 drives the inner frame structure to slide along the sliding track 7 to the designated position. After stopping, the inner frame lifting foot 3 slowly falls until it contacts the ground. At this point, the driving operation cycle of a driving and steering device suitable for deserts is completed. Then, the above driving trajectory is repeated to make the device travel back and forth in complex sandy terrain. This embodiment adopts a "inchworm"-like biomimetic movement mode to adapt to the complex desert environment.
[0033] When the equipment is preparing to turn, such as Fig. 3 As shown, after the inner frame lifting foot 3 travels to the designated position, it slowly lowers until it contacts the ground. Then, the outer lifting foot slowly rises to the designated position. At this time, the rotation power unit 8 drives the outer frame structure to make a 90° turning motion. After turning to the designated position, the inner frame lifting foot 3 slowly rises, and the outer lifting foot slowly lowers until it contacts the ground. The sliding power unit 5 drives the inner frame structure to slide along the sliding track 7 to the designated position. Then, the inner frame lifting foot 3 slowly lowers until it contacts the ground, and the outer lifting foot rises to the designated position. At this time, the rotation power unit 8 drives the outer frame structure to make another 90° turning motion. At this time, the driving and turning cycle of a driving and turning device suitable for desert is completed.
[0034] This embodiment uses an outer frame lifting foot 1 and an inner frame lifting foot 3 to reduce the contact between the equipment and the ground. Different modifications or arrangements can also be made according to the terrain requirements.
[0035] The embodiment solves the problems of the existing desert driving steering device, such as not easy to enter complex sand land, difficult operation, and the like; the embodiment can cope with various complex geographical environments, is suitable for driving or steering in various complex sand lands, and further improves the device maneuverability level, and ensures the driving and steering efficiency of the device in the desert.
