Embodiment Construction

[0030]The following describes the present invention in detail with reference to the drawings and specific embodiments.

[0031]figure 1 A rear-walking self-propelled working machine is shown, which can specifically be a lawn mower, a snowplow, a small cart or other working machines with self-propelled functions. As an optional implementation manner, a lawn mower is taken as an example for introduction. Such asfigure 1 As shown, the lawn mower 100 mainly includes a handle device 11 and a host 12. Among them, the host 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 host 12 for the user to operate the lawn mower 100 on the rear side of the lawn mower 100. It can be understood that other rear-walking self-propelled working machines such as snowplows, trolleys, etc. may also include components such as the handle device 11, the host 12, and the walking ...

Abstract

The invention discloses a backward walking type self-propelled working machine. The backward walking type self-propelled working machine comprises a main unit and a handle device, wherein the main unit comprises a walking assembly and a driving motor for driving the walking assembly; the handle device is connected to the main unit to allow a user to operate the backward walking type self-propelledworking machine on the rear side of the backward walking type self-propelled working machine; the handle device comprises an operating piece, a connecting rod, a pressure sensor and a pressing piece;the operating piece comprises a holding part for the user to hold; the connecting rod is connected to the main unit; the pressure sensor is arranged between the operating piece and the connecting rod; when the holding part is subjected to thrust, the pressing piece applies acting force in the preset linear direction to the sensor so as to drive the pressure sensor to deform; and the ratio of thecomponent force, in the preset linear direction, of the thrust borne by the holding part to the deformation quantity, in the preset linear direction, of the pressure sensor is larger than or equal to40 N / mm and smaller than or equal to 1200 N / mm. 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]The rear-walking self-propelled working machine lawn mower is generally a machine used by users to mow domestic lawns. When the user pushes the lawn mower to mow the lawn for a long time, it will consume a lot of physical energy. In order to reduce the labor intensity of the operator when cutting grass, lawn mowers that can walk on the market appear. In some existing lawn mowers with a self-propelled function, the self-propelled function requires manual control and can only output a constant speed, and the user can only follow the lawn mower and perform grass cutting operations. In some more advanced lawn mowers, the self-propelled system is complicated to operate, the user's comfort is poor, and there are many drawbacks. The invention provides a back-walking self-propelled working machine whose self-propelled speed can automatically a...
