Referring to fig. 9 to 14, the switch assembly 20 includes a start switch 22, a control member 23 triggering the start switch 22, and first and second driving members 24 and 25 driving the control member 23 to move.

The start switch 22 is used to control the operation of the mower 100, and the start switch 22 may be a push trigger switch.

Referring to fig. 10, when the switch assembly 20 is in the initial state, the start switch 22, the control member 23, the first driving member 24 and the second driving member 25 do not interfere with each other.

Referring to fig. 13, when the first driving member 24 is driven, the first driving member 24 contacts and drives the control member 23 to move to the first position, and the start switch 22 is in the non-triggered state.

Here, "the first driving member 24 contacts and drives the control member 23 to move to the first position" means that the first driving member 24 gradually moves closer to the control member 23 when being driven, and when the first driving member 24 contacts the control member 23 and the first driving member 24 continues to move, the first driving member 24 drives the control member 23 to move, and the control member 23 moves from the initial position to the first position.

In addition, during the process that the first driving member 24 contacts and drives the control member 23 to move to the first position, the start switch 22 is changed from the initial state to the to-be-triggered state, where the "to-be-triggered state" means that the control member 23 has approached or has contacted the start switch 22, but the start switch 22 is still in the non-triggered state.

Referring to fig. 14, when the second driving member 25 is driven, the second driving member 25 contacts and drives the control member 23 to move from the first position to the second position, and the control member 23 triggers the start switch 22, i.e. the start switch 22 is changed from the to-be-triggered state to the triggered state.

Here, "the second driving member 25 contacts and drives the control member 23 to move from the first position to the second position" means that the second driving member 25 gradually moves closer to the control member 23 when being driven, and when the second driving member 25 contacts the control member 23 (at this time, the control member 23 is kept at the first position) and the second driving member 25 continues to move, the second driving member 25 drives the control member 23 to continue to move, and the control member 23 moves from the first position to the second position; the "trigger state" means that the control member 23 presses the start switch 22, and the start switch 22 is in an on state.

It can be seen that, in the switch assembly 20 of this embodiment, the control member 23 triggering the start switch 22 is controlled by the first driving member 24 and the second driving member 25 at the same time, the first driving member 24 drives the control member 23 to move so that the start switch 22 is in an un-triggered state, and the second driving member 25 drives the control member 23 to move so that the start switch 22 is in a triggered state, that is, the start switch 22 can be triggered only under the condition that the first driving member 24 and the second driving member 25 are sequentially driven, so that dual protection of the start switch 22 is realized, and the use safety of a user is improved. Further, after the start switch 22 is in the triggered state, the driving of the first driving member 24 can be canceled.

In an embodiment, with continued reference to fig. 9 to 14, the housing 21 of the switch assembly 20 has a receiving space S and a through hole S' communicating with the receiving space S, and the start switch 22, the control member 23 and the second driving member 25 are all located in the receiving space S.

Referring to fig. 10 to 12, the first driving member 24 is a button assembly 24, one end of the button assembly 24 passes through the through hole S' and is disposed adjacent to the control member 23, and the other end of the button assembly 24 is disposed at a side of the housing 21 away from the accommodating space S.

Specifically, referring to fig. 11, the housing 21 has a pi-shaped recess 214, and the button assembly 24 includes a pressing portion 241 and a pushing portion 242, wherein the pressing portion 241 and the pushing portion 242 are fixed to each other by a screw 243.

The switch assembly 20 further includes a first rotating shaft 26 and a second rotating shaft 27, the control member 23 is connected to the first rotating shaft 26, and the second driving member 25 is connected to the second rotating shaft 27.

Here, the control member 23 is a rocker 23, the second driving member 25 is a lever 25, the axial direction of the first shaft 26 and the axial direction of the second shaft 27 are parallel to each other, and the axial direction of the first shaft 26 is parallel to the reference plane M, and the movement direction of the driven button assembly 24 is perpendicular to the reference plane M, i.e., the movement direction of the button assembly 24 is perpendicular to the axial direction of the first shaft 26.

The first rotation shaft 26 and the second rotation shaft 27 may be disposed at equal heights, that is, the distances between the first rotation shaft 26, the second rotation shaft 27 and the reference plane M are equal.

In addition, the switch assembly 20 further includes a handle portion 28, the handle portion 28 being connected to and driving the lever 25.

Here, the handle portion 28 is a U-shaped handle, two ends of the handle portion 28 are movably connected to two ends of the housing 21, respectively, and the driven handle portion 28 is rotated toward or away from the grip portion 133.

Thus, when the operator operates the grip portion 133, the handle portion 28 can be operated at the same time, which is convenient and quick, and the distance between the grip portion 133 and the handle portion 28 is small, and the grip portion 133 and the handle portion 28 can be operated with the same hand.

It can be understood that the first rotating shaft 26 may be disposed at the housing 21, the rocker 23 may rotate about the first rotating shaft 26 as a central axis, the handle portion 28 is fixedly connected with the lever 25, the handle portion 28 may rotate relative to the housing 21, and the second rotating shaft 27 is a connection portion between the lever 25 and the handle portion 28.

In this embodiment, the rocker 23 includes a control end 231 and a first action end 232 located at two sides of the first rotating shaft 26, and one end of the lever 25 is connected to the handle 28, and the other end is a second action end 251.

Here, referring to fig. 12, the first acting end 232 includes a first hook portion 2321, the second acting end 251 includes a second hook portion 2511, the hook direction of the first hook portion 2321 faces downward, and the hook direction of the second hook portion 2511 faces upward.

When the first acting end 232 interacts with the second acting end 251, the first hook 2321 and the second hook 2511 are engaged with each other.

The second acting end 251 further includes a recess 2512, where the recess 2512 includes a bottom 2512a and two opposite side walls 2512b (only one side wall 2512b is illustrated here) connected to the bottom 2512a, the second hook portion 2511 is disposed at the bottom 2512a, and the second hook portion 2511 is clamped between the two side walls 2512 b.

That is, the second hooking portion 2511 may be formed by hollowing out a middle partial region of the shift lever 25.

Thus, when the second hook portion 2511 and the first hook portion 2321 are engaged with each other, the first hook portion 2321 is just limited between the two side walls 2512b, so as to prevent the rocker 23 from rocking in the axial direction of the first rotating shaft 26 when rotating.

It can be appreciated that the first acting end 232 may also include a groove, and the second hook 2511 is limited in the groove when the second hook 2511 and the first hook 2321 are engaged with each other.

In the present embodiment, during the process of changing the start switch 22 from the initial state to the triggered state, the rocker 23 rotates in the first direction a (counterclockwise direction) relative to the first rotating shaft 26, and the lever 25 rotates in the second direction B (clockwise direction) relative to the second rotating shaft 27, and the first direction a is opposite to the second direction B.

The switch assembly 20 further includes a first reset element (not shown) connected to the rocker 23 and a second reset element (not shown) connected to the lever 25, wherein the first reset element controls the rocker 23 to reset and the second reset element controls the lever 25 to reset during the resetting of the start switch 22 (i.e., during the process of the start switch 22 returning from the triggered state to the initial state).

Next, the operation flow of the switch assembly 20 of the present embodiment will be described in detail.

Referring to fig. 10, when the switch assembly 20 is in the initial state, the spring 29 is in the initial state, a gap is provided between the pressing portion 241 of the button assembly 24 and the housing 21, and the start switch 22, the rocker 23, the button assembly 24 and the lever 25 do not interfere with each other, and the first acting end 232 of the rocker 23 and the second acting end 251 of the lever 25 are disposed adjacent to each other.

Referring to fig. 13, when the button assembly 24 is driven, i.e. the pressing portion 241 of the button assembly 24 is pressed, the spring 29 is compressed, the pushing portion 242 of the button assembly 24 drives the rocker 23 to rotate to the first position along the first direction a relative to the first rotation axis 26, at this time, the first acting end 232 of the rocker 23 is located at the third position, the control end 231 of the rocker 23 gradually approaches the start switch 22, and the second acting end 251 of the lever 25 is located at the initial position.

Referring to fig. 14, when the lever 25 is driven to rotate the handle 28 toward the grip portion 133, the handle 28 drives the lever 25 to rotate along the second direction B relative to the second shaft 27, at this time, the first acting end 232 is kept at the third position, the second acting end 251 gradually approaches the first acting end 232 to rotate, and then the second acting end 251 drives the first acting end 232 to rotate from the third position to the fourth position, and the control end 231 applies a force to the start switch 22 to trigger the start switch 22.

It should be noted that, when the second acting end 251 contacts the first acting end 232, the acting force applied to the button assembly 24 may be removed, and the button assembly 24 is reset under the action of the spring 29, and at this time, the rocker 23 is continuously driven to rotate along the first direction a by the pushing action of the second acting end 251 to trigger the start switch 22.

When the force applied to the handle portion 28 is removed, the second reset element drives the shifter lever 25 to reset, and at the same time, the first reset element drives the rocker 23 to reset, so that the start switch 22 is restored to the off state.

Next, the operation principle of the switch assembly 20 is further explained with reference to fig. 15 to 17.

In the present embodiment, the driven rocker 23 rotates relative to the first rotation shaft 26 to form a first rotation region P1, and the driven lever 25 rotates relative to the second rotation shaft 27 to form a second rotation region P2, and an overlapping region P3 and a non-overlapping region P4 are disposed between the first rotation region P1 and the second rotation region P2.

It can be appreciated that when the first acting end 232 and the second acting end 251 are both located in the non-overlapping region P4, the first acting end 232 and the second acting end 251 do not interfere with each other when they rotate, and when the first acting end 232 and the second acting end 251 are both located in the overlapping region P3, the first acting end 232 and the second acting end 251 interfere with each other when they rotate.

Referring to fig. 15, when the switch assembly 20 is in the initial state, the first active end 232 and the second active end 251 are both located in the non-overlapping region P4.

Specifically, the first acting end 232 and the second acting end 251 are located on the same side of the overlapping region P3 and do not interfere with each other, where the first acting end 232 and the second acting end 251 are located in a non-overlapping region P4 below the overlapping region P3, that is, a lower non-overlapping region and an upper non-overlapping region near the upper and lower sides of the overlapping region P3, respectively, and the first acting end 232 and the second acting end 251 are both located in the lower non-overlapping region.

Referring to fig. 16, when the button assembly 24 is actuated, the first acting end 232 rotates from the non-overlapping region P4 to the overlapping region P3, and the second acting end 251 is located in the non-overlapping region P4.

Referring to fig. 17, when the lever 25 is driven, the second acting end 251 rotates from the non-overlapping region P4 to the overlapping region P3, and the second acting end 251 abuts against the first acting end 232.

It can be appreciated that referring to fig. 18, since the first and second active ends 232 and 251 are both located in the non-overlapping region P4 when the switch assembly 20 is in the initial state, the first and second active ends 232 and 251 do not interfere with each other when the non-overlapping region P4 rotates.

In this case, if the handle 28 is driven to rotate the lever 25 along the second direction B, the second acting end 251 enters the overlapping region P3 from the non-overlapping region P4, and the first acting end 232 is still located in the non-overlapping region P3, i.e. the position of the rocker 23 is unchanged, so that the start switch 22 cannot be triggered, and even if the button assembly 24 is driven again, only the first acting end 232 can be driven to enter the overlapping region P3 from the non-overlapping region P4, so that the start switch 22 cannot be triggered.

That is, in the event of false triggering (either the handle portion 28 is actuated, the button assembly 24 is actuated, or only the handle portion 28 is actuated), the second actuating end 251 is located above the first actuating end 232, and the rocker 23 cannot trigger the actuating switch 22.

In addition, in the case of false triggering, the rotation process of the deflector 25 is not blocked by the rocker 23, so that the damage risk of the deflector 25 and the rocker 23 can be effectively reduced.
