[0050] See also Figures 1 to 6 The present application provides a snowplow 100, including a main body 110, a handle assembly 120 and a manned assembly 130. The main body 110 includes a snowplow assembly 113, a main body housing 111 and a walking assembly 112. The main body housing 111 supports the snowplow assembly 113, and the walking assembly 112 is connected to the main body housing 111. The handle assembly 120 is connected to the main body 110, and the manned assembly 130 is connected to the main body 110. The manned assembly 130 includes a manned portion 131 for supporting a user. When the snowplow 100 is moving, the user can be located in the manned portion 131, and the snowplow 100 drives the user forward without the user having to exert any effort.

[0051] The snowplow 100 of the present application is an improvement on the existing push-type snowplow. By adding a manned component 130, the user does not need to walk with the snowplow 100, but stands or sits on the manned part 131, and the snowplow 100 drives the user forward. The weight of the snowplow 100 is greater than or equal to 40kg and less than or equal to 100kg. In some embodiments, the weight of the snowplow 100 is greater than or equal to 45kg and less than or equal to 80kg. In some embodiments, the weight of the snowplow 100 is greater than or equal to 50kg and less than or equal to 70kg.

[0052] 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.

[0053] 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.

[0054] The snowplow 100 has a hand-push mode and a manned mode. When the snowplow 100 is in the hand-push mode, the manned component 130 is in a first state relative to the main body 110, and when the snowplow 100 is in the manned mode, the manned component 130 is in a second state relative to the main body 110. In the hand-push mode, the user can stand on the ground and hold the handle component 120 to follow the snowplow 100. At this time, the manned component 130 is in the first state relative to the main body 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 body 110, and the user can be located in the manned part 131, and the snowplow 100 drives the user to walk, without the user having to exert any effort, saving time and effort.

[0055] In some embodiments, the manned assembly 130 is detachable relative to the main machine 110. When the snow blower 100 is in the hand-push mode, the manned assembly 130 is detached relative to the main machine 110. By detaching the manned assembly 130, space is saved and it is convenient to store the manned assembly 130. In the manned mode, the manned assembly 130 is installed to the main machine 110. The manned assembly 130 and the main machine 110 can be connected by components such as pins, hooks, and plugs that are easy to disassemble.

[0056] When the snowplow 100 is in the hand-push mode, the manned assembly 130 is in the first position relative to the main body 110, and when the snowplow 100 is in the manned mode, the manned assembly 130 is in the second position relative to the main body 110. By switching the position of the manned assembly 130, in the hand-push mode, the manned assembly 130 will not interfere with the user, saving space.

[0057] In some embodiments, the manned component 130 is foldable or rotatable to switch between a first position and a second position. As a feasible embodiment, the manned part 131 includes a pedal 1311, and the pedal 1311 is foldable or rotatable relative to the main machine 110. Specifically, one end of the pedal 1311 is rotatably connected to the main machine housing 111, and the pedal 1311 can switch between a horizontal position and a vertical position. The pedal 1311 and the main machine housing 111 can be rotatably connected through a hinge assembly. When the pedal 1311 is in a horizontal position, the manned component 130 is in a second position relative to the main machine 110, and the user can stand on the pedal 1311. When the pedal 1311 is in a vertical position, the manned component 130 is in a first position relative to the main machine 110, and the user can stand on the ground and walk with the snowplow 100. Since the pedal 1311 is in a vertical state, space is saved.

[0058] In some embodiments, the manned assembly 130 has no power itself, and the power for the snowplow 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.

[0059] The snowplow 100 further includes a control device, which is used to control the travel assembly 112. In some embodiments, the control device receives user input to the handle assembly 120 to control the travel assembly 112. In other embodiments, when the snowplow 100 is in a hand-push mode, the control device receives user input to the handle assembly 120 to control the travel assembly 112, and when the snowplow 100 is in a passenger mode, the control device at least receives user input to the passenger assembly 130 to control the travel assembly 112.

[0060] 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.

[0061] When the snowplow 100 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.

[0062] 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.

[0063] 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 snowplow 100 is in the manned mode, and in the lifted state, the snowplow 100 is in the hand-push mode.

[0064] 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.

[0065] 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.

[0066] In some embodiments, the manned component 130 includes a pedal 1311, the pedal 1311 includes a treading area, and the treading area is provided with a pressure sensor, and the snowplow 100 moves forward or backward 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, 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 100 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 100 moves backward. Among them, the first set value is greater than the second set value.

[0067] Furthermore, the snowplow 100 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 100 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 100 moves forward at the second gear speed.

[0068] In some embodiments, the treading area includes at least a left treading area and a right treading area, and the snowplow 100 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 100, 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 100 turns left.

[0069] The pressure sensor and torque sensor are both electrically connected to the control device, and the control device controls the travel component 112 by receiving the pressure value and the torque value.

[0070] In some embodiments, the passenger assembly 130 includes passenger wheels 132 , which support the passenger unit 131 . When the whole machine moves, the passenger wheels 132 are driven to move, thereby driving the passenger unit 131 to move.

[0071] In some embodiments, the passenger assembly 130 has power, and the power for the snowplow 100 to move can come from the travel assembly 112 or from the passenger assembly 130. Specifically, the passenger assembly 130 includes passenger travel wheels 132 and a passenger travel motor. The passenger travel wheels 132 support the passenger part 131, and the passenger travel motor is connected to the passenger travel wheels 132 to drive the passenger travel wheels 132. The passenger travel motor drives the passenger travel wheels 132 to move, thereby driving the entire machine to move.

[0072] In some embodiments, the passenger walking motor is a hub motor.

[0073] In some embodiments, two passenger travel wheels 132 are provided, and the two passenger travel wheels 132 are spaced apart in the left-right direction, and a passenger travel motor is provided for each passenger travel wheel 132. The steering can be controlled according to the speed difference between the two passenger travel motors. As a feasible implementation, when the speed of the passenger travel motor on the left side is greater than the speed of the passenger travel motor on the right side, and the difference between the two is greater than or equal to the first speed value, the snowplow 100 turns right.

[0074] When the passenger travel motor is turned on to drive the passenger travel wheel 132 to travel, the travel motor of the travel assembly 112 is turned off to prevent interference. In some embodiments, the passenger travel motor and the travel motor of the travel assembly 112 can be turned on at the same time, and a differential clutch transmission is used between the two to prevent interference.

[0075] The host 110 further includes a battery pack, which is detachably connected to the host housing 111 to at least supply power to the walking component 112. The battery pack is detachable for easy charging. The battery pack can supply power to the walking motor of the walking component 112 to drive the walking wheels 1121 of the walking component 112 to walk.

[0076] In some embodiments, the battery pack is used to power the manned travel motor, and the manned travel motor and the travel assembly 112 share the battery pack to reduce the number of components.

[0077] Typically, the battery pack is disposed in the main housing 111. In the front-to-back direction, the distance between the battery pack and the passenger assembly 130 is greater than or equal to 750 mm and less than or equal to 950 mm. By setting an appropriate distance, the length of the connection between the battery pack and the passenger assembly 130 can be reduced to reduce power loss.

[0078] The host 110 includes a first electrical interface, and the manned component 130 includes a second electrical interface detachably connected to the first electrical interface. After the first electrical interface is connected to the second electrical interface, the battery pack can power the manned walking motor, and the battery pack can also power the pressure sensor on the manned component 130.

[0079] When the first electrical interface is connected to the second electrical interface, the snowplow 100 is in the manned mode. The control device can identify the hand-push mode and the manned mode by detecting the conduction state of the first electrical interface and the second electrical interface.

[0080] In other embodiments, the passenger assembly 130 includes a first power source independent of the battery pack, and the first power source is used to power the passenger travel motor. When the battery pack is used to power the travel assembly 112 and the power is exhausted, the first power source can be used to power the passenger travel motor to drive the whole machine to travel, thereby extending the battery life.

[0081] The manned component 130 includes a control component, which is configured to control the manned walking wheel 132 to move forward, backward or turn. In some embodiments, the control component includes an adjustment button, and by pressing the adjustment button, the manned walking wheel 132 is controlled to switch between the forward state, the backward state and the turning state. In some embodiments, the control component includes a voice receiving module, and the voice receiving module receives voice to control the manned walking wheel 132 to switch between the forward state, the backward state and the turning state. Among them, the adjustment button can be pressed by hand or by foot.
