Abstract

A riding lawn mower includes a seat, a chassis configured to support the seat, a cutting assembly mounted to the chassis, a walking assembly configured to drive the riding lawn mower to walk on a plane, and a steering wheel assembly. The steering wheel assembly includes a steering wheel operable by the user and a connecting rod configured to connect the steering wheel and the chassis. The steering wheel assembly further includes a pivot assembly that rotatably connects the connecting rod and the chassis, and the pivot assembly enables the steering wheel assembly to switch between a working position and a storage position. A distance between the steering wheel and the plane when the steering wheel assembly is in the storage position is smaller than a distance between the steering wheel and the plane when the steering wheel assembly is in the working position.

First claim

What is claimed is:

1 . A riding lawn mower, comprising:
a seat for a user to sit thereon; a chassis configured to support the seat; a cutting assembly mounted to the chassis, the cutting assembly comprising a cutting member for cutting grass; a walking assembly configured to drive the riding lawn mower to walk on a plane; and a steering wheel assembly comprising a steering wheel operable by the user, a connecting rod configured to connect the steering wheel and the chassis, and a pivot assembly that rotatably connects the connecting rod and the chassis and enables the steering wheel assembly to switch between a working position and a storage position; wherein a distance between the steering wheel and the plane when the steering wheel assembly is in the storage position is smaller than a distance between the steering wheel and the plane when the steering wheel assembly is in the working position, and wherein the pivot assembly is disposed under the seat so that the steering wheel is located towards a side of the seat when the steering wheel assembly is switched to the storage position.

2 . The riding lawn mower of claim 1 , wherein the connecting rod has a first end connected with the steering wheel and a second end connected with the chassis through the pivot assembly.

3 . The riding lawn mower of claim 1 , further comprising a left cover member and a right cover member, wherein the left cover member is located on a left side of the seat and the right cover member is located on a right side of the seat.

4 . The riding lawn mower of claim 3 , wherein the right cover member covers the pivot assembly.

5 . The riding lawn mower of claim 3 , wherein a height of the left cover member is lower than a height of the right cover member.

6 . The riding lawn mower of claim 1 , wherein, when the steering wheel assembly is in the working position, a difference of a perpendicular distance from a highest point of the steering wheel assembly to the plane and a perpendicular distance from a sitting surface of the seat to the plane is greater than or equal to 30 cm and less than or equal to 50 cm.

7 . The riding lawn mower of claim 1 , wherein, when the steering wheel assembly is in the working position, a perpendicular distance from a highest point of the steering wheel assembly to the plane is greater than or equal to 80 cm and less than or equal to 120 cm.

8 . The riding lawn mower of claim 1 , wherein, when the steering wheel assembly is in the working position, a distance between orthographic projections of the steering wheel assembly and a back of the seat on the plane is greater than or equal to 60 cm and less than or equal to 100 cm.

9 . The riding lawn mower of claim 1 , wherein the steering wheel assembly further comprises an adjustment device operable to adjust a height of the steering wheel.

10 . The riding lawn mower of claim 1 , wherein the steering wheel is configured to rotate about a first axis to control a steering direction of the riding lawn mower, the steering wheel has a first limit position when rotating clockwise about the first axis, and a second limit position when rotating counterclockwise about the first axis, and an angle that the steering wheel rotates from the first limit position to the second limit position is less than or equal to 380 degrees.

11 . The riding lawn mower of claim 10 , wherein the steering wheel further has an initial position, an angle that the steering wheel rotates from the initial position to the first limit position is less than or equal to 190 degrees, and an angle that the steering wheel rotates from the initial position to the second limit position is less than or equal to 190 degrees.

12 . The riding lawn mower of claim 1 , further comprising a display interface mounted on the steering wheel.

13 . The riding lawn mower of claim 1 , further comprising a paddle shifter mounted near the steering wheel.

14 . The riding lawn mower of claim 1 , further comprising a pedal assembly operable by the user to control a walking speed of the riding lawn mower, wherein the riding lawn mower has a central axis, the riding lawn mower is at least partially symmetrical about a central vertical plane passing through the central axis, the connecting rod has a first end connected with the steering wheel and a second end connected with the chassis, and the pedal assembly and the second end of the connecting rod are located on a same side of the central vertical plane.

15 . The riding lawn mower of claim 14 , further comprising a step bar mounted to the chassis, wherein the step bar is located on an opposite side of central vertical plane to the pedal assembly.

16 . A riding machine, comprising:
a seat for a user to sit thereon; a chassis configured to support the seat; a walking assembly configured to drive the riding machine to walk on a plane; and a steering wheel assembly comprising a steering wheel operable by the user, a connecting rod configured to connect the steering wheel and the chassis, and a pivot assembly that rotatably connects the connecting rod and the chassis and enables the steering wheel assembly to switch between a working position and a storage position; wherein a distance between the steering wheel and the plane when the steering wheel assembly is in the storage position is smaller than a distance between the steering wheel and the plane when the steering wheel assembly is in the working position, wherein the connecting rod is rotatably mounted on a right side or a left side of the seat through the pivot assembly so that at least a part of the connecting rod is located on the right side or the left side of the seat and is adjacent a bottom plate of the chassis.

17 . The riding machine of claim 16 , wherein the connecting rod has a first end connected with the steering wheel and a second end connected with the chassis, and the pivot assembly comprises a first part fixedly connected with the chassis and a second part fixedly connected with the second end of the connecting rod.

18 . The riding machine of claim 16 , wherein, in the storage position, the connecting rod is lied down on the chassis.

19 . A riding lawn mower, comprising:
a seat; a chassis supporting the seat; a cutting assembly mounted to the chassis, the cutting assembly comprising a cutting member for cutting grass; a drive assembly configured to drive the riding lawn mower to move on a plane; and a steering wheel assembly comprising a steering wheel, a connecting rod configured to operably couple the steering wheel and the chassis, and a pivot assembly that rotatably connects the connecting rod to the chassis, the pivot assembly being rotatable to enable the steering wheel assembly to switch between a working position and a storage position; and a pedal assembly mounted to the chassis and operable to control a drive speed of the riding lawn mower, wherein a distance between the steering wheel and the plane when the steering wheel assembly is in the storage position is smaller than a distance between the steering wheel and the plane when the steering wheel assembly is in the working position, and wherein the steering wheel is adjacent the pedal assembly when the steering wheel assembly is in the storage position.
