[0063] In this application, the terms "calculate", "judge", "control", "determine", "identify", etc. refer to the operations and processes of a computer system or similar electronic computing device (e.g., controller, processor, etc.).
[0064] The present application provides a power tool, which may be a lawn mower, a snow sweeper, a wheelbarrow or other self-propelled machine. Figures 1 to 6 , the power tool is a lawn mower 100. The lawn mower 100 includes a main unit 110, a handle assembly 120 and a passenger assembly 130. The main unit 110 includes a functional assembly, a main unit housing 111 and a travel assembly 112. The main unit housing 111 supports the functional assembly, and the travel assembly 112 is connected to the main unit housing 111. The handle assembly 120 is connected to the main unit 110, and the passenger assembly 130 is connected to the main unit 110. The passenger assembly 130 includes a passenger part 131 for supporting a user. When the whole machine is moving, the user can be located in the passenger part 131, and the lawn mower 100 drives the user forward without the user having to exert any effort.
[0065] In the case where the power tool is a lawn mower 100, the functional component is a blade component for mowing grass, and the blade component is driven by a driving motor to rotate to achieve a cutting function. The lawn mower 100 of the present application is an improvement on the existing push-type lawn mower. By adding a manned component 130, the user does not need to walk with the lawn mower 100, but stands or sits on the manned part 131, and the lawn mower 100 drives the user forward.
[0066] The manned assembly 130 can be connected to the rear of the host 110 to facilitate the user to hold the handle assembly 120. In some embodiments, the manned assembly 130 can also be connected to the left or right side of the host 110, and the handle assembly 120 can also be detachable.
[0067] In some embodiments, the manned portion 131 includes a seat, and the user can sit on the seat to increase comfort. In some embodiments, the manned portion 131 includes a pedal 1311, and the user can stand on the pedal 1311 to save space.
[0068] The power tool has a hand-push mode and a manned mode. When the power tool is in the hand-push mode, the manned component 130 is in a first state relative to the main unit 110, and when the power tool is in the manned mode, the manned component 130 is in a second state relative to the main unit 110. In the hand-push mode, the user can stand on the ground and hold the handle assembly 120 to follow the power tool to walk. At this time, the manned component 130 is in the first state relative to the main unit 110 and will not interfere with the user's walking. In the manned mode, the manned component 130 is in the second state relative to the main unit 110, and the user can be located in the manned part 131, and the power tool drives the user to walk, without the user having to exert any effort, saving time and effort. One difference between the hand-push mode and the manned mode is that in the hand-push mode, the user's feet need to touch the ground to walk, while in the manned mode, the user's feet do not need to touch the ground to walk.
[0069] In some embodiments, the manned portion 131 is foldable or rotatable to switch between a first state and a second state. As a feasible implementation, the manned portion 131 includes a pedal 1311, which is foldable or rotatable relative to the host 110. Specifically, one end of the pedal 1311 is rotatably connected to the host housing 111, and the pedal 1311 can switch between a horizontal state and a vertical state. The pedal 1311 and the host housing 111 can be rotatably connected via a hinge assembly. When the pedal 1311 is in a horizontal state, the manned assembly 130 is in a second state relative to the host 110, and the user can stand on the pedal 1311. When the pedal 1311 is in a vertical state, the manned assembly 130 is in a first state relative to the host 110, and the user can stand on the ground and walk with the power tool. Since the pedal 1311 is in a vertical state, space is saved.
[0070] In some embodiments, the passenger assembly 130 is detachable relative to the main unit 110. In the push mode, the passenger assembly 130 is disassembled. By disassembling the passenger assembly 130, space is saved and the passenger assembly 130 is convenient to store. In the passenger mode, the passenger assembly 130 is installed to the main unit 110. The passenger assembly 130 and the main unit 110 can be connected by components such as pins, hooks, and plugs that are easy to disassemble. In some embodiments, when the power tool is in the push mode, the passenger assembly 130 can also be installed to the main unit 110. In some embodiments, when the power tool is in the push mode, the user can also hold the handle assembly 120 or other handles for the user to hold by hand.
[0071] In some embodiments, the manned assembly 130 has no power itself, and the power for the lawn mower 100 to move comes from the walking assembly 112. The walking assembly 112 includes a walking wheel 1121 and a walking motor. When in use, the walking motor drives the walking wheel 1121 to move, thereby driving the entire machine to move.
[0072] When the power tool is a lawn mower 100, the running wheels 1121 of the lawn mower 100 include a front wheel and a rear wheel, and the front wheel is a universal wheel for easy steering. The running motor is used to drive the rear wheel to rotate.
[0073] The power tool further includes a control device, which is used to control the travel assembly 112. When the power tool is in a hand-push mode, the passenger assembly 130 is in a first state relative to the main body 110, and the control device receives a user's input to the handle assembly 120 to control the travel assembly 112. When the power tool is in a passenger mode, the passenger assembly 130 is in a second state relative to the main body 110, and the control device at least receives a user's input to the passenger assembly 130 to control the travel assembly 112.
[0074] In the push mode, the user can stand on the ground and walk with the power tool while holding the handle assembly 120. At this time, the manned assembly 130 is in the first state relative to the main body 110 and will not interfere with the user's walking. The control device receives the user's input to the handle assembly 120 to control the walking assembly 112. In the manned mode, the manned assembly 130 is in the second state relative to the main body 110. The user can be located in the manned part 131 and driven by the power tool to walk. The control device at least receives the user's input to the manned assembly 130 to control the walking assembly 112.
[0075] In the passenger mode, since the user is located in the passenger part 131, it is convenient to operate the passenger component 130. At this time, the user does not need to hold the handle component 120, so the control device at least receives the user's input to the passenger component 130 to control the walking component 112, which is convenient for user operation.
[0076] When the power tool is in the passenger mode, the control device is configured to receive user input to the handle assembly 120 to control the travel assembly 112. In the passenger mode, the user is located in the passenger portion 131 and can operate the passenger assembly 130 or the handle assembly 120, giving the user more options and improving the user experience.
[0077] In the hand-push mode, the control device is in the first control state when receiving the user's input to the handle assembly 120 to control the walking assembly 112. In the passenger mode, the control device is in the second control state when receiving at least the user's input to the passenger assembly 130 to control the walking assembly 112. The control device automatically identifies the passenger mode and the hand-push mode to switch between the first control state and the second control state. By automatically identifying the passenger mode and the hand-push mode, the control device can switch between the first control state and the second control state in a timely manner to meet the needs of the user.
[0078] In some embodiments, the control device includes a selection switch 150, and the user switches between the manned mode and the hand-push mode by operating the selection switch 150. The selection switch 150 has a pressed state and a lifted state. In the pressed state, the power tool is in the manned mode, and in the lifted state, the power tool is in the hand-push mode.
[0079] The control device is configured to control the walking assembly 112 to enter the forward mode, the backward mode or the steering mode. In some embodiments, the control device includes a mode button 140, and the walking assembly 112 is configured to switch between the forward mode, the backward mode and the steering mode by operating the mode button 140. The mode button 140 can be provided on both the handle assembly 120 and the manned assembly 130, so that the user can operate according to his own needs. In some embodiments, the control device includes a voice receiving module, and the voice receiving module receives the voice to control the walking assembly 112 to switch between the forward mode, the backward mode and the steering mode. The voice receiving module can be provided on both the handle assembly 120 and the manned assembly 130, so that the user can operate according to his own needs.
[0080] The control device is configured to adjust the speed of the walking component 112. In some embodiments, the speed of the walking component 112 can be adjusted by a speed adjustment button. In some embodiments, the speed of the walking component 112 can be adjusted by a voice receiving module.
[0081] In some embodiments, the manned component 130 includes a pedal 1311, and the pedal 1311 includes a pedal area. The pedal area is provided with a pressure sensor, and the power tool moves forward or backward according to the pressure value of the pressure sensor. As a feasible implementation, the pedal area is divided into a front pedal area and a rear pedal area. When the pressure value of the front pedal area is greater than a first set value and the pressure of the rear pedal area is less than a second set value, the power tool moves forward. When the pressure value of the front pedal area is less than the second set value and the pressure of the rear pedal area is greater than the first set value, the power tool moves backward. Among them, the first set value is greater than the second set value.
[0082] Furthermore, the power tool can adjust the speed according to the pressure value of the pressure sensor. As a feasible implementation, the pedaling area is divided into a front pedaling area and a rear pedaling area. When the pressure value of the front pedaling area is greater than a first set value and less than a third set value, the power tool moves forward at a first gear speed. When the pressure value of the front pedaling area is greater than the third set value, the power tool moves forward at a second gear speed.
[0083] In some embodiments, the pedal area includes at least a left pedal area and a right pedal area, and the power tool realizes steering according to the pressure difference between the left pedal area and the right pedal area. As a feasible implementation, the left pedal area is divided into a front pedal area and a rear pedal area, and the right pedal area is divided into a front pedal area and a rear pedal area. During the forward movement of the power tool, when the pressure value of the front pedal area of the left pedal area is greater than the pressure value of the front pedal area of the right pedal area, and the difference between the two is greater than or equal to a first set difference, the power tool turns left.
[0084] In some embodiments, the manned assembly 130 includes a clamping rod 1312, and a torque sensor is connected to the clamping rod 1312, and the power tool turns according to the torque of the torque sensor.

In the hand-push mode, the user can stand on the ground and hold the handle component 120 to walk with the snowplow 200. At this time, the manned component 130 is in the first state relative to the main unit 110 and will not interfere with the user's walking. In the manned mode, the manned component 130 is in the second state relative to the main unit 110, and the user can be located in the manned part 131, and the snowplow 200 drives the user to walk, without the user having to exert any effort, saving time and effort.
[0112] In some embodiments, the passenger assembly 130 is detachable relative to the main machine 110. When the snow blower 200 is in the push mode, the passenger assembly 130 is detached relative to the main machine 110. By detaching the passenger assembly 130, space is saved and the passenger assembly 130 is convenient to store. In the passenger mode, the passenger assembly 130 is installed to the main machine 110.

Since the pedal 1311 is in a vertical state, space is saved.
[0115] In some embodiments, the manned assembly 130 has no power itself, and the power for the snowplow 200 to move comes from the walking assembly 112. The walking assembly 112 includes a walking wheel 1121 and a walking motor. When in use, the walking motor drives the walking wheel 1121 to move, thereby driving the entire machine to move.

[0117] In the passenger mode, since the user is located in the passenger part 131, it is convenient to operate the passenger component 130. At this time, the user does not need to hold the handle component 120, so the control device at least receives the user's input to the passenger component 130 to control the walking component 112, which is convenient for user operation.
[0118] When the snowplow 200 is in the passenger mode, the control device is configured to receive user input to the handle assembly 120 to control the travel assembly 112.

In some embodiments, the control device includes a voice receiving module, and the voice receiving module receives the voice to control the walking assembly 112 to switch between the forward mode, the backward mode and the steering mode. The voice receiving module can be provided on both the handle assembly 120 and the manned assembly 130, so that the user can operate according to his own needs.
[0122] The control device is configured to adjust the speed of the walking component 112. In some embodiments, the speed of the walking component 112 can be adjusted by a speed adjustment button.

As a feasible implementation, the treading area is divided into a front treading area and a rear treading area, and when the pressure value of the front treading area is greater than a first set value and the pressure of the rear treading area is less than a second set value, the snowplow 200 moves forward. When the pressure value of the front treading area is less than the second set value and the pressure of the rear treading area is greater than the first set value, the snowplow 200 moves backward. Among them, the first set value is greater than the second set value.
[0124] Furthermore, the snowplow 200 can adjust the speed according to the pressure value of the pressure sensor. As a feasible implementation, the treading area is divided into a front treading area and a rear treading area. When the pressure value of the front treading area is greater than the first set value and less than the third set value, the snowplow 200 moves forward at the first gear speed. When the pressure value of the front treading area is greater than the third set value, the snowplow 200 moves forward at the second gear speed.
[0125] In some embodiments, the treading area includes at least a left treading area and a right treading area, and the snowplow 200 turns according to the pressure difference between the left treading area and the right treading area. As an achievable implementation, the left treading area is divided into a front treading area and a rear treading area, and the right treading area is divided into a front treading area and a rear treading area. During the forward movement of the snowplow 200, when the pressure value of the front treading area of the left treading area is greater than the pressure value of the front treading area of the right treading area, and the difference between the two is greater than or equal to a first set difference, the snowplow 200 turns left.
