[0025] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0026] See Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a tracked lawnmower chassis structure, including a frame 100, a travel motor 200, and a travel track 300; guide wheels 110 and load-bearing wheels 120 are provided on both sides of the frame 100, the travel motor 200 is mounted on the frame 100, and a drive wheel 210 is provided on the travel motor 200; multiple load-bearing wheels 120 are located between two guide wheels 110, and the travel track 300 is wound around the drive wheel 210, guide wheels 110, and load-bearing wheels 120; the relationship between the distance L between two adjacent load-bearing wheels 120 and the pitch p of the travel track 300 is: L=p*n+p / 2, where n is the number of sections of the travel track 300.

[0027] Specifically, guide wheels 110 are provided at both ends of the front of multiple load-bearing wheels 120 to improve the stability of the entire track structure. Moreover, the relationship between the distance L between two adjacent load-bearing wheels 120 and the pitch p of the traveling track 300 is: L=p*n+p / 2, where n is the number of sections of the traveling track 300. With this setting, it is ensured that there is always one tooth of the traveling track 300 that can engage the load-bearing wheel 120, and dragging will not occur.

[0028] It should be noted that the tracked lawnmower chassis provided in this embodiment has a simple structure and can maintain stable operation under various working conditions, making it suitable for different working scenarios. Moreover, by setting the spacing of the load-bearing wheels 120, the walking track 300 can be fixed on the load-bearing wheels 120 during operation, reducing the impact of machining accuracy on transmission quality, preventing the track from dragging or skipping teeth in complex working environments, thus affecting work efficiency and improving vehicle passability and safety.

[0029] The diameter of the load-bearing wheel 120 is smaller than the diameter of the guide wheel 110. The diameter of the guide wheel 110 is smaller than the diameter of the drive wheel 210.

[0030] See Figure 1 , Figure 2 and Figure 3 As shown, in the optional embodiment, the tracked lawnmower chassis structure also includes a wheel frame 101, which is fixedly installed on the outside of the frame 100; the bottom of the wheel frame 101 is provided with both a guide wheel 110 and a load-bearing wheel 120, and the top of the wheel frame 101 is provided with a load-bearing wheel 120.

[0031] Specifically, the wheel frame 101 is fixedly installed on the frame 100. The bottom of the wheel frame 101 is provided with a guide wheel 110 and a load-bearing wheel 120, and the top is provided with a load-bearing wheel 120. This arrangement improves assembly efficiency and facilitates disassembly and maintenance later.

[0032] See Figure 1 , Figure 2 and Figure 3As shown, in the optional embodiment, the tracked lawnmower chassis structure also includes a tension wheel 130, which is mounted on the frame 100 via a tensioning rod; the tension wheel 130 is located behind the wheel frame 101 along the forward direction of the lawnmower.

[0033] Specifically, a tensioning wheel 130 is provided on the outer side of the frame 100. The tensioning wheel 130 ensures the tension of the track 300 and the meshing transmission between the track 300, the drive wheel 210, and the load-bearing wheel 120.

[0034] The track 300 is wrapped around the drive wheel 210, guide wheel 110, load-bearing wheel 120 and tension wheel 130 in a parallelogram shape. This arrangement ensures that the track 300 always has a tooth that can engage the load-bearing wheel 120, preventing dragging and making the operation more stable.

[0035] See Figure 1 , Figure 2 and Figure 3 As shown, in the optional embodiment, the tracked lawnmower chassis structure further includes a mowing platform 400 and a hydraulic push rod 500; a rotating shaft bracket 410 is provided on the mowing platform 400, and the rotating shaft bracket 410 is rotatably mounted on the frame 100 via a rotating shaft 420; a fixed partition 140 is provided on the frame 100, one end of the hydraulic push rod 500 is mounted on the fixed partition 140, and the other end is connected to the mowing platform 400; the fixed partition 140 is located behind the rotating shaft 420 along the forward direction of the lawnmower.

[0036] Specifically, a pivot bracket 410 is provided on the mowing platform 400. The pivot bracket 410 is rotatably mounted on the frame 100 via a pivot shaft 420. A hydraulic push rod 500 is also provided on the mowing platform 400. The end of the hydraulic push rod 500 away from the mowing platform 400 is mounted on a fixed partition 140 inside the frame 100. With this configuration, the pitch and swing angle of the mowing platform 400 can be adjusted by controlling the hydraulic push rod 500.

[0037] It should be noted that the fixed partition 140 along the forward direction of the lawnmower is located behind the rotating shaft 420. This arrangement lengthens the hydraulic push rod 500 and increases the driving arm of the lawnmower 400 swinging, thus making it easier to control the hydraulic push rod 500.

[0038] In addition, one end of the hydraulic push rod 500 is set on the top of the fixed partition 140, and the rotating shaft 420 is pivotally connected to the bottom of the frame 100. This arrangement can increase the lifting height of the mower 400, reduce the reaction force of the mower 400 on the vehicle body, prevent the mower 400 from lifting the vehicle body and causing the track 300 to slip due to reduced ground pressure, and at the same time reduce the consumption of battery power.

[0039] It should be noted that the mowing platform 400 is equipped with a mowing structure, which can be set up by those skilled in the art according to actual mowing needs, and will not be described in detail here.

[0040] See Figure 1 , Figure 2 and Figure 3 As shown, in the optional embodiment, the fixed partition 140 divides the interior of the frame 100 into a battery compartment 150 and a motor compartment 160. The drive motor 200 is located in the motor compartment 160, and the battery compartment 150 is equipped with a battery assembly 600.

[0041] Specifically, the entire frame 100 is used to house the walking motor 200 and the battery assembly 600, thereby increasing the battery capacity and extending the battery life of the tracked lawnmower chassis structure provided in this embodiment. It also increases the power of the walking motor 200, improves the output power, and thus improves the work efficiency. It is also more environmentally friendly with no exhaust emissions.

[0042] See Figure 1 , Figure 2 and Figure 3 As shown, in the optional scheme of this embodiment, there are two walking motors 200, and the two walking motors 200 drive the walking tracks 300 located on both sides of the frame 100 respectively; there is a clearance space 220 between the two walking motors 200 for the hydraulic push rod 500 to pass through.

[0043] Specifically, two walking motors 200 are installed inside the frame 100. The frame 100 has a working channel adapted to the walking motors 200, so that the drive wheel 210 at the output end of the walking motor 200 can pass through the working channel and be exposed on the outside of the frame 100, thereby enabling the walking tracks 300 on both sides of the frame 100 to be controlled independently.

[0044] It should be noted that there is a clearance space 220 between the two travel motors 200 for the hydraulic push rod 500 to pass through. With this arrangement, the hydraulic push rod 500 will not interfere with the travel motors 200 when it is working.

[0045] It should be noted that wireless remote control and other structures can be added to the frame 100 to enable remote control, intelligent navigation and unmanned operation, thereby reducing the waste of manpower and material resources.

[0046] See Figure 1 As shown, this embodiment provides a lawnmower, including a tracked lawnmower chassis structure.

[0047] Specifically, the lawnmower provided in this embodiment has the advantages of the aforementioned tracked lawnmower chassis structure compared to the prior art, which will not be elaborated here.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
