[0027] In practice:

[0028] The vehicle body, power unit, and drive wheels can be mounted on the frame to achieve the basic functions of a lawnmower. The frame adopts a telescopic structure, with screw 20 and lead screw 10 fixedly connected. Two frame beams 30 are symmetrically connected in parallel to both sides of lead screw 10 and screw 20 via connecting beams. The specific scheme is as follows:

[0029] 1. Telescopic Frame Design: Utilizing a nested structure, the main frame is composed of square tubing, secured to different telescopic positions via bolts or clips. Deformation allows the chassis width to be adjusted, adapting to various complex terrains.

[0030] 2. Towing function reserved: A standard towing hook interface is set at the rear of the frame. It is made of high-strength steel and the hook can withstand a certain amount of tension. The interface is reinforced to ensure towing safety.

[0031] 3.

Simultaneously, an airflow guidance channel is designed to work in conjunction with the lawnmower's mowing device, allowing grass clippings to smoothly enter the grass collection box.

[0032] 4. Snowplow Function Reserved: The front of the vehicle frame has pre-installed mounting interfaces for the snowplow 110 and snow blower. These are mounted via a bracket, the angle and height of which can be adjusted as needed. The snowplow 110 uses an adjustable-angle connection.

[0033] 5. Snow blowing function reserved: The snow blower is connected to the frame via a quick-connect device, and the power source can be linked with the lawnmower's power system.

[0034] 6. Pre-installed soil turning function: An interface for installing a soil turner is provided at the rear of the vehicle frame. It uses a suspended connection and the turning depth can be adjusted hydraulically or mechanically. The soil turning device is connected to the power take-off shaft of the lawn vehicle for power transmission.

[0035] 7. Powertrain Adaptability Design: The frame utilizes a universal powertrain mounting platform, allowing for the installation of both gasoline-powered engines and electric drive systems. It is equipped with switchable power interfaces and control systems, enabling users to choose the power source according to their needs.

[0036] The multi-functional wheeled lawnmower frame in this application adopts a telescopic frame structure, combining frame beams, lead screws, connecting beams, and adjustment devices. By changing the relative position of the adjustment device on the lead screw, the width of the frame can be adjusted to adapt to different sites. Furthermore, multiple equipment interfaces are reserved on the frame, allowing for the installation of corresponding equipment at different interfaces. This enables the frame to serve multiple purposes, reduces equipment purchase costs, and meets the usage habits and environmental protection needs of different users.
