Embodiment Construction

[0031] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0032] figure 1 A rear-propelled self-propelled working machine is shown, which may specifically be a lawnmower, a snowplow, or a trolley, or other working machines with self-propelled functions. As an optional implementation manner, a lawn mower is taken as an example for introduction below. Such as figure 1 As shown, the lawn mower 100 mainly includes a handle device 11 and a host 12 . Wherein, the main engine 12 includes a walking assembly 121 and a power mechanism (not shown in the figure). Specifically, the lawn mower 100 is a hand push lawn mower 100 . The handle device 11 is connected to the main unit 12 for a user to operate the lawn mower 100 at the rear side of the lawn mower 100 . It can be understood that other rear-propelled self-propelled working machines such as snowplows and trolleys may also include components such a...

Abstract

The invention discloses a backward walking type self-propelled working machine. The backward walking type self-propelled working machine comprises a walking assembly, a drive motor and a handle device, and further comprises a sensing module and a control module; the backward walking type self-propelled working machine has a low-speed driving mode and a self-adaptive mode; when thrust is smaller than a first preset value, the backward walking type self-propelled working machine is in the low-speed driving mode; when the thrust is larger than a second preset value, the backward walking type self-propelled working machine is also in the self-adaptive mode; when the backward walking type self-propelled working machine is in the low-speed driving mode, the control module controls the rotating speed of the drive motor to be smaller than or equal to a first preset rotating speed; and when the backward walking type self-propelled working machine is in the self-adaptive mode, the control modulecontrols the drive motor to change towards an expected rotating speed obtained according to the thrust, and the expected rotating speed is larger than the first preset rotating speed. The backward walking type self-propelled working machine is convenient to operate and high in reliability.

Description

technical field [0001] The invention relates to a garden tool, in particular to a rear-walking self-propelled working machine. Background technique [0002] Rear-propelled self-propelled working machine lawn mowers are generally the machines that users use to mow domestic lawns. When the user pushes the mower to mow the lawn on the grass for a long time, it will consume a lot of physical strength. In order to alleviate the operator's labor intensity when mowing, self-propelled lawnmowers have appeared on the market. In some existing lawn mowers with self-propelled function, the self-propelled function requires human control, and can only output a constant speed, and the user can only follow the lawn mower and perform mowing operations. In some advanced mowers, the self-propelled system is complicated to operate, the user's comfort is poor, and there are many disadvantages. The invention provides a rear-walking self-propelled working machine whose self-propelled speed can ...
