However, current multi-functional lawnmowers have independently configured power drive components for both the mowing and additional functional structures, as well as a separate power source for the machine's walking mechanism. This parallel arrangement of multiple power systems results in a large number of parts, increasing manufacturing costs and adding to the burden of movement and operation. Summary of the Invention

[0022] This invention proposes a lawnmower.

[0023] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the lawnmower includes: Frame 100; The traveling unit 200 is mounted on the frame 100 and is used to drive the frame 100 to move. A lawn mowing assembly 300 is mounted on the frame 100; Functional components are located on the frame 100; The power unit 500 is located on the frame 100 and is driven to connect with both the mowing unit 300 and the functional unit to drive the mowing unit 300 and the functional unit to start and stop.

[0024] In the technical solution of this invention, by integrating a mowing component 300 and a functional component onto the frame 100, the device possesses mowing and other functions such as snow throwing or rotary tillage. Furthermore, by providing a walking unit 200 at the bottom of the frame 100, the device can be moved to different locations to perform mowing and other operations. Simultaneously, the device also includes a power component 500 that simultaneously drives both the mowing component 300 and the functional component, eliminating the need for separate power drive structures for each component. This reduces the number of power components in the entire machine, simplifies the overall structure, lowers manufacturing costs, and reduces the overall weight, thereby reducing the burden of movement and operation.

[0025] Specifically, the frame 100, serving as the load-bearing structure of this multi-functional lawnmower, can be made of high-strength steel. This ensures the overall structural strength while reducing its own weight and minimizing unnecessary power consumption. Alternatively, the frame 100 can be made of aluminum alloy, further reducing the overall weight and improving the lawnmower's mobility. Aluminum alloy also possesses excellent corrosion resistance, enabling it to withstand humid and dusty outdoor working environments and extending the equipment's lifespan.

[0026] The walking unit 200 can be configured as a wheeled walking structure or a tracked walking structure, without limitation. In this embodiment, the walking unit 200 is configured as a tracked walking structure, which has better traction and can operate stably on uneven terrain. The tracked walking structure includes a track frame 250, a drive wheel 220, a guide wheel 230, a track support roller 240, a track body 210, and a tension adjustment assembly; the drive wheel 220 and the guide wheel 230 are rotatably mounted at the front and rear ends of the track frame 250, respectively, and the track support roller 240 is fixedly mounted on the upper part of the track frame 250 and rolls in connection with the inner wall of the track within the track body 210; the track body 210 surrounds and covers the outside of the drive wheel 220, the guide wheel 230, and the track support roller 240, and moves along the track. The drive motor is fixed to the frame 100 and is connected to the drive wheel 220 for transmission, thereby driving the drive wheel 220 to rotate. The rotation of the drive wheel 220 drives the entire tracked walking structure to rotate through the track body 210, thereby driving the whole machine to move. The tension adjustment component is set between the track frame 250 and the guide wheel 230, which can adjust the tension of the track body 210 to avoid the track body 210 from slipping or derailing, and ensure the stable operation of the walking unit 200.

[0027] The mowing assembly 300 is used to perform mowing operations at the location where the machine has moved. The mowing assembly 300 can be mounted protruding from the front of the frame 100 or at the bottom front side of the frame 100. It should be avoided being mounted at the rear of the frame 100, especially not in the same direction as the side track bodies 210. This prevents incomplete mowing and uneven stubble height when the frame 100 moves and crushes the weeds before mowing. By mounting the mowing assembly 300 at the front of the frame 100, it passes over the weeds before the tracks, cutting them first and improving the efficiency of the mowing operation.

[0028] Please refer to Figure 3 and Figure 4 In an embodiment of the present invention, the power assembly 500 includes: Drive component 510 is mounted on frame 100; The drive pulley 520 is rotatably mounted on the frame 100, and the drive unit 510 is driven to drive the drive pulley 520 to rotate. The first transmission structure 530 is a transmission connection between the drive pulley 520 and the functional components; The mowing assembly 300 is mounted on the drive pulley 520 and rotates synchronously with the drive pulley 520.

[0029] Specifically, the drive unit 510 is mounted on the frame 100 and can be a motor or a combination of a motor and a reducer. The output end of the drive unit 510 is connected to a drive rod 511, which passes downward through the frame 100 and is coaxially connected to the drive pulley 520. The drive rod 511 and the drive pulley 520 can be connected by a key, which is not limited here. The mowing assembly 300 is directly mounted on the drive pulley 520 and rotates synchronously with it. The drive pulley 520 is driven by the functional component through the first transmission structure 530. In this way, the rotation of the drive pulley 520 can simultaneously output power to the mowing assembly 300 and the functional component. One power source drives the operation of two sets of working structures at the same time, thereby saving the redundant structure of setting separate power sources for each, and further reducing the overall size and load of the machine.

[0030] Please refer to Figure 3 and Figure 4 In an embodiment of the present invention, the lawn mowing assembly 300 includes: The cutter head 310 is coaxially connected to the drive pulley 520 and rotates synchronously. The cutter 320 is mounted on the cutter head 310, and the rotation of the cutter head 310 is used to rotate the cutter 320.

[0031] Specifically, the cutter head 310 is generally designed as a disc-shaped structure, coaxially fixed to the lower end face of the drive pulley 520 by fastening bolts, making installation and disassembly more convenient. Alternatively, a slot can be cut into the cutter head 310, and the cutter head 310 can be keyed to the drive pulley 520. Directly mounting the cutter head 310 onto the drive pulley 520, with the cutter head 310 and the drive pulley 520 coaxial, can also ensure dynamic balance during rotation, thereby reducing power loss. The cutting blades 320 are located on the outer periphery of the cutter head 310 and extend radially. A single cutting blade 320 can be provided, or multiple cutting blades can be spaced apart along the circumference of the cutter head 310. When the cutter head 310 rotates with the drive pulley 520, the cutter head 310 drives the cutting blades 320 to perform a circular rotational motion. This can also be achieved through other means. Figure 3 As shown, the cutter 320 is mounted on a mounting bracket, which is snapped into the cutter head 310. At least two sets of latches are provided on the side of the cutter head 310 away from the drive pulley 520, engaging with the mounting bracket. This allows the mounting bracket to be mounted on the cutter head 310, thus rotating synchronously with both the cutter head 310 and the drive pulley 520. After repeated use, when the cutter 320 wears out, the mounting bracket can be directly removed from the cutter head 310 to replace it with a new cutter 320 and mounting bracket. The snap-fit ​​method makes assembly and disassembly more convenient. The cutter 320 cuts weeds by rotating. By directly mounting the cutter head 310 onto the drive pulley 520, the transmission structure is simplified, power transmission loss is reduced, and the rotation of the cutter 320 is more stable, ensuring better cutting results.

[0032] In one embodiment, the cutter 320 can be hinged to the cutter head 310 via a pin, allowing the cutter 320 to swing up and down slightly during rotation. It is understood that when the lawnmower encounters an obstacle, the swinging of the cutter 320 can buffer the impact of the obstacle, prevent the cutter 320 from breaking, and improve the durability of the lawnmower assembly 300.

[0033] Please refer to Figure 3 and Figure 4 In an embodiment of the present invention, the first transmission structure 530 includes a first synchronous pulley 531 and a first synchronous belt 532. The first synchronous belt 532 is wound around the drive pulley 520 and the first synchronous pulley 531, and the functional component is connected to the first synchronous pulley 531 in a transmission connection.

[0034] Specifically, the outer side of the drive pulley 520 is provided with synchronous tooth grooves for the first synchronous belt 532 to mesh and drive. The first synchronous belt 532 is wound around the outside of the drive pulley 520 and the first synchronous pulley 531 when it is tensioned. When the drive pulley 520 is driven to rotate by the drive member 510, the first synchronous pulley 531 can be driven to rotate synchronously by the meshing of the synchronous teeth and the synchronous belt, thereby transmitting power to the functional component connected to the first synchronous pulley 531. That is, the lawn mowing component 300 and the functional component can be driven simultaneously by one power component 500.

[0035] Please refer to Figure 3 and Figure 4 In an embodiment of the present invention, the lawnmower further includes a power generation component 600, which includes: A generator 610 is mounted on the vehicle frame 100 and has a power input terminal. The second transmission structure 620 is connected to the drive pulley 520 and the power input end, and transmits the rotational power of the drive pulley 520 to the generator 610 to drive the generator 610 to generate electricity.

[0036] Specifically, the generator 610 is mounted above the frame 100. The drive pulley 520 transmits power to the power input end of the generator 610 through the second transmission structure 620, enabling the generator 610 to generate electricity. The electrical energy generated by the generator 610 can be stored in a battery and used to power the motors of the subsequent power assembly 500 or the walking unit 200. Alternatively, it can directly power the walking unit 200 and the power assembly 500 without the need for external power cables or additional engines, further simplifying the structure. This application improves power utilization and reduces power waste by simultaneously driving the mowing assembly 300, the functional components, and the generator 610 through the drive pulley 520.

[0037] Please refer to Figure 3 and Figure 4In an embodiment of the present invention, the power input end is configured as a rotor, and the second transmission structure 620 includes a second synchronous pulley 621 and a second synchronous belt 622. The second synchronous pulley 621 is coaxially connected to the rotor, and the second synchronous belt 622 is wound around the drive pulley 520 and the second synchronous pulley 621 so as to drive the rotor to rotate and generate electrical energy through the rotation of the second synchronous pulley 621.

[0038] Specifically, when the drive pulley 520 rotates, it drives the second synchronous pulley 621 to rotate via the second synchronous belt 622. The second synchronous pulley 621 then drives the rotor of the generator 610 to rotate coaxially, causing the rotor to cut magnetic field lines and generate electrical energy. Similar to the first transmission structure 530, the surface of the drive pulley 520 is also provided with synchronous tooth grooves that mesh with the second synchronous belt 622. Stable power transmission is achieved through meshing, avoiding slippage and ensuring stable rotor rotation.

[0039] In order to make more rational use of the space of the frame 100 and improve the space utilization rate, the first synchronous belt 532 and the second synchronous belt 622 extend in opposite directions, and the first synchronous belt 532 and the second synchronous belt 622 are axially spaced at the drive pulley 520.

[0040] Please refer to Figure 2 In an embodiment of the present invention, the lawnmower further includes a lifting assembly, which includes: Mounting plate 700, lawn mowing component 300, functional component and power component 500 are all mounted on mounting plate 700; The lifting power component 710 is located on the frame 100 and is driven to connect with the mounting plate 700 to drive the mounting plate 700 to lift.

[0041] Specifically, the lifting power component 710 can be configured as an electric push rod, or as an electric cylinder or a pneumatic cylinder. The fixed end of the lifting power component 710 is hinged to the frame 100, and the output end is hinged to the mounting plate 700. The lifting and lowering of the mounting plate 700 is achieved by extending and retracting the output end of the lifting power component 710. The mounting plate 700 is horizontally positioned, and the mowing assembly 300, functional components, generator 610, and power component 500 are all mounted on the mounting plate 700. The lifting and lowering of the mounting plate 700 can drive the mowing assembly 300 and functional components to rise and fall together. By adjusting the height of the mowing assembly 300, it can adapt to different stubble height requirements and adjust the mowing height. Simultaneously, when the mower moves, the mounting plate 700 can be raised to increase its height above the ground, avoiding wear caused by friction with the ground and collisions with protruding obstacles on the ground, thus extending its service life.

[0042] Please refer to Figure 1 and Figure 2In an embodiment of the present invention, the functional component is one of the following: snow removal component 400, rotary tillage structure, and roller brush sweeping structure. When the functional component is configured as snow removal component 400, snow removal component 400 includes: Snowplow 410 is located at the front end of the vehicle frame 100; The auger structure 420 is rotatably mounted on the snowplow frame 410, and the auger structure 420 rotates about the first axis; The reversing transmission structure connects the auger structure 420 and the first synchronous pulley 531 to drive the auger structure 420 to rotate.

[0043] Specifically, the snowplow frame 410 is located at the front end of the vehicle frame 100. The snowplow frame 410 is fixed to the front end of the vehicle frame 100 by bolts or a quick-release buckle structure, enabling quick disassembly and replacement to accommodate functional components with different functions. The auger structure 420 is arranged horizontally and rotates on the snowplow frame 410 around the first axis. The rotation of the auger structure 420 allows for the collection, transport, and throwing of snow. A reversing transmission structure connects the auger structure 420 and the first synchronous pulley 531. This can be a bevel gear set structure, converting the rotation direction output by the first synchronous pulley 531 to match the rotation direction of the auger structure 420, ensuring smooth power transmission and integrating snow removal and mowing operations. In this embodiment, the rotation axis of the first synchronous pulley 531 is vertical and perpendicular to the first axis. By changing the direction of power transmission through the reversing transmission structure, the auger structure 420 can be stably driven to rotate around the first axis.

[0044] Please refer to Figure 1 and Figure 2 In an embodiment of the present invention, the reversing transmission structure includes a right-angle reduction gearbox 430 and a transmission rod 440 extending along a second direction. The input end of the right-angle reduction gearbox 430 is coaxially connected to the first synchronous pulley 531, and the output end of the right-angle reduction gearbox 430 is connected to the transmission rod 440. A worm gear 451 is provided at one end of the transmission rod 440 away from the right-angle reduction gearbox 430. The auger structure 420 is provided with a worm wheel 450. The worm gear 451 meshes with the worm wheel 450. The first synchronous pulley 531 rotates to drive the auger structure 420 to rotate through the right-angle reduction gearbox 430, the transmission rod 440, the worm gear 451, and the worm wheel 450.

[0045] If a functional component needs to be replaced, the end of the transmission rod 440 connected to the right-angle reducer 430 can be disassembled to replace it with another functional component, which can then be assembled onto the output end of the right-angle reducer. If the functional component to be replaced also requires the extension of the transmission rod 440 to transmit power, like the snow removal component 400, the end of the transmission rod 440 connected to the right-angle reducer 430 can be retained, while the end of the transmission rod 440 connected to the worm gear 451 can be removed. There are no restrictions here, and the structure can be adjusted according to actual needs.

[0046] Specifically, the second direction is perpendicular to the first axis in a top-view angle. Power is transmitted sequentially from the first synchronous pulley 531 to the right-angle reduction gearbox 430, transmission rod 440, and worm gear 451. Then, through the meshing transmission of the worm gear 451 and worm wheel 450, the auger structure 420 is driven to rotate stably around the first axis. By adjusting the direction of power transmission through the multi-stage reversing transmission of the right-angle reduction gearbox 430 and the worm wheel 450 and worm gear 451, not only can speed up and increase torque, ensuring that the auger structure 420 has sufficient power to rotate and gather snow, but it will also prevent it from stopping or jamming due to excessive snow resistance, ensuring a stable output of snow gathering and transportation. Combined with the reverse self-locking feature of the worm wheel 450 and worm gear 451, when the auger structure 420 encounters large resistance and cannot rotate, it will not cause reverse impact and damage to the transmission structure of the power component 500, thus extending its service life.

[0047] Please refer to Figure 1 and Figure 2 In an embodiment of the present invention, the auger structure 420 includes a first auger part 422 and a second auger part 423, the first auger part 422 and the second auger part 423 are respectively located at both ends of the worm gear 450, and the spiral directions of the first auger part 422 and the second auger part 423 are opposite.

[0048] Specifically, the auger structure 420 includes a connecting shaft 421 and a first auger section 422 and a second auger section 423 disposed on the connecting shaft 421. The worm gear 450 is coaxially disposed on the connecting shaft 421 and is located in the middle of the first auger section 422 and the second auger section 423. When the worm gear 450 is driven to rotate by the worm 451, it will simultaneously drive the connecting shaft 421 to rotate. The rotation of the connecting shaft 421 drives the first auger section 422 and the second auger section 423 to rotate synchronously. Since the two spiral directions are opposite, the snow can be gathered and transported to the snow outlet in the middle during the rotation process, avoiding the accumulation of snow at both ends of the auger structure 420 and improving the efficiency of snow removal operations. In this embodiment, a snow tube 470 and an impeller 460 are also provided on the snow removal frame 410. The impeller 460 is arranged at the snow outlet position in the middle of the auger structure 420 and can be installed on the transmission rod 440. As the transmission rod 440 rotates about the second direction as the axis, the auger structure 420 pushes the accumulated snow to the impeller 460 area. The high-speed rotation of the impeller 460 generates centrifugal force and throws the snow out, which is then directionally thrown by the snow tube 470, thereby realizing continuous snow throwing operation. Setting the first auger part 422 and the second auger part 423 as a symmetrical structure can also ensure the dynamic balance of the auger structure 420 during rotation, reduce vibration during rotation, and improve operational stability.

[0049] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
