[0028] like Figures 1 to 3As shown, a tracked walking device includes a drive unit 10, a wheel set 20, and a track 30, wherein the track is fitted over the wheel set; wherein,

[0029] like Figure 2 As shown, the driving component 10 includes a first driving component 11, a second driving component 12 connected to the end of the first driving component 11, and a third driving component 13 connected to the end of the first driving component 11; as Figure 3 As shown, the wheel set 20 includes a first wheel set 21 connected to the first drive component 11, a second wheel set 22 connected to the second drive component 12, and a third wheel set 23; the track 30 is sleeved on the outside of the first wheel set 21, the second wheel set 22, and the third wheel set 23.

[0030] like Figure 3 As shown, the first drive component 11 is a tensioning cylinder, the second drive component 12 is a support cylinder, the third drive component 13 is a contouring cylinder, the first wheel set 21 is a tensioning wheel set, the second wheel set 22 is a support wheel set, and the third wheel set 23 is a drive wheel set.

[0031] In this embodiment, as Figure 3 and Figure 4 As shown, the supporting cylinder is placed inside a load-bearing housing 40. A first connecting shaft 41 and a second connecting shaft 42 are inserted into the load-bearing housing 40. The first connecting shaft 41 is movably connected to the head end of a drive housing 50, and the second connecting shaft 42 is movably connected to the vehicle body.

[0032] In this embodiment, as Figure 4 and Figure 5 As shown, the end of the drive housing 50 is connected to the axle of the drive wheel assembly, as... Figure 6 As shown, a power output shaft 51 is inserted into the drive housing 50, a first gear 52 is provided on the power output shaft 51, and a third gear 53 is provided on the axle of the drive wheel assembly. The first gear 52 and the third gear 53 are connected by a second gear 54.

[0033] In this embodiment, the power output shaft 51 and the second gear 54 are placed inside the drive housing 50, and both ends of the power output shaft 51 and the second gear 54 are mounted on the side wall of the drive housing 50.

[0034] In this embodiment, as Figure 7As shown, a first rotating frame 43 is rotatably connected to the axle of the tensioning wheel assembly. The top of the first rotating frame 43 is connected to the head end of the tensioning cylinder. A second rotating frame 44 is connected to the bottom of the first rotating frame 43. A third rotating frame 45 is connected to the end of the second rotating frame 44. The upper middle position of the third rotating frame 45 is connected to the end of the support cylinder. The support wheel assembly is also connected to the connecting frame 70.

[0035] In this embodiment, Figure 3 As shown, one end of the load-bearing box 40 is connected to the first end of the second rotating frame 44 through the bottom of the tensioning wheel axle.

[0036] In this embodiment, Figure 3 As shown, an angle sensor 60 is also connected between the load-bearing box 40 and the second drive component 12. The angle sensor 60 is used to detect the rotation angle value of the load-bearing box 40 and the drive box 50 during the vehicle's uphill process. When the rotation angle is too large, an alarm message can be issued by the alarm device on the vehicle to remind the driver.

[0037] In this embodiment, as Figure 7 As shown, the support roller assembly has two sets, each movably connected to the third rotating frame 45 via a connecting frame 70. The connecting frame 70 is equipped with a scraper blade 221 for cleaning mud from the support roller assembly. By installing the scraper blade, mud can be scraped from the support roller assembly regardless of the amount or consistency of the mud adhering to the rollers. The scraper blade of this invention has a simple structure and is easy to install and clean; this invention can reduce power loss in the walking mechanism.

[0038] In this embodiment, the tensioning cylinder presses the tensioning wheel against the track 30 to prevent the track from loosening or veering during travel.

[0039] In this embodiment, the load-bearing housing 40 connects the vehicle body to the track 30 and also connects other components, serving as a load-bearing connection. The extension and retraction of the contouring cylinder in this embodiment drives the drive housing 50 to rotate relative to the first connecting shaft 41, mimicking the shape of the ground during climbing and preventing the track from directly touching the ground due to gravity. The support roller assembly can stabilize the ground pressure value, and the extension and retraction of the support cylinder causes the third rotating frame 45 to rotate, thus achieving a contouring effect. The drive housing 50 connects to the vehicle body and is the power source during vehicle movement; the friction between the drive wheels and the track causes the track to move.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
