Abstract

A mower includes an electric motor, a main machine body, an electronic component, and an operating assembly. The main machine body extends in a forward-backward direction. The operating assembly includes a handle assembly and a first operating member. The handle assembly is rotatably connected to the main machine body and configured to be held to operate the mower to run. The first operating member is rotatably connected to the handle assembly to control a walking state of the mower. The first operating member is formed with a fitting surface fitting with the handle assembly. In response to the first operating member being operated to rotate and approach the handle assembly, the fitting surface is capable of substantially fitting flush with the handle assembly to form a unitary component that is capable of being held.

First claim

What is claimed is:

1. A mower, comprising:
an electric motor configured to drive a mowing element to rotate for mowing;
a main machine body configured for the electric motor to be mounted and configured to extend in a forward-backward direction;
an electronic component electrically connected to the electric motor and configured to control power output of the mower; and
an operating assembly operable for control of walking and the power output of the mower,
wherein the operating assembly comprises a handle assembly rotatably connected to the main machine body and configured to be held to operate the mower to run and a first operating member rotatably connected to the handle assembly to control a walking state of the mower formed with a fitting surface adapted to substantially fit flush with the handle assembly when the first operating member is operated to rotate and approach the handle assembly, and
wherein the first operating member comprises a contact portion having a bent region and a straight line region and an included angle is formed between an extension direction of the bent region and an extension direction of the straight line region.

2. The mower of claim 1 , wherein the fitting surface is disposed at the contact portion, the handle assembly comprises a hold portion, and in response to the fitting surface being in contact with the handle assembly, the fitting surface fits with the hold portion.

3. The mower of claim 1 , wherein the included angle is greater than or equal to 20° and less than or equal to 30°.

4. The mower of claim 1 , wherein the handle assembly comprises two connecting rods and a connection housing connecting the two connecting rods and the contact portion is provided with the fitting surface and two main body portions for connecting the contact portion to the connection housing.

5. The mower of claim 4 , wherein the operating assembly further comprises a speed regulator disposed between the two main body portions.

6. The mower of claim 5 , wherein a length L 3 of a portion of the speed regulator that can be operated is greater than or equal to 20 mm and less than or equal to 25 mm.

7. The mower of claim 2 , wherein the fitting surface is an arc surface that can substantially fit with an outer surface of the hold portion.

8. The mower of claim 7 , wherein the handle assembly comprises two connecting rods, the hold portion comprises an intermediate portion extending in a left-right direction, the intermediate portion is a cylinder, and a center line of the cylinder extends in the left-right direction, the hold portion further comprises a first connecting portion connected with the intermediate portion and one of the two connecting rods and a second connecting portion connected with an other one of the two connecting rods, the fitting surface comprises an intermediate fitting surface which is in contact with the hold portion, a first fitting surface and a second fitting surface arranged at both ends of the intermediate fitting surface, the first fitting surface is in contact with the first connecting portion, and the second fitting surface is which is in contact with the second connecting portion.

9. The mower of claim 8 , wherein a cross-sectional line of the intermediate fitting surface in a plane perpendicular to the center line is a circular arc.

10. The mower of claim 9 , wherein a center angle corresponding to the circular arc is greater than or equal to 30 degrees and less than or equal to 180 degrees.

11. The mower of claim 2 , wherein the fitting surface is arranged on a back side of the hold portion.

12. The mower of claim 1 , wherein the operating assembly further comprises a second operating member rotatably connected to the handle assembly and the second operating member is disposed on a front side of the first operating member.

13. The mower of claim 1 , wherein the main machine body is further formed with a support leg configured to support the mower and the support leg is disposed at a back side of the main machine body.

14. The mower of claim 1 , further comprising a walking assembly for the mower to walk wherein the walking assembly comprises a first walking wheel and a second walking wheel and the second walking wheel is disposed behind the first walking wheel.

15. The mower of claim 1 , wherein the main machine body is further formed with a support leg configured to support the mower and the support leg is disposed at a back side of the main machine body, the mower further comprising a walking assembly for the mower to walk wherein the walking assembly comprises a first walking wheel and a second walking wheel and the second walking wheel is disposed behind the first walking wheel, and
a backmost end of the support leg is substantially flush with a backmost end of the second walking wheel in a plane perpendicular to the forward-backward direction.

16. The mower of claim 1 , wherein the operating assembly is rotatably connected to the main machine body and the main machine body is further formed with a first limiting portion for limiting rotation of the operating assembly.

17. The mower of claim 1 , wherein the operating assembly further comprises a connection rod for connecting the handle assembly and the first operating member, the connection rod extends along a second linear direction parallel to an axis direction of the connection rod and is provided with a telescopic portion for adjusting a length of the connection rod the connection rod further comprises an adjusting member for adjusting a telescopic state, and the adjusting member is configured to rotate around a rotation axis perpendicular to the second linear direction.
